Description

The invention relates to a bed, which is in particular a hospital or a nursing bed.

Care beds and hospital beds with height-adjustable underframes and adjustable mattress overlays are available for elderly and dependent persons as well as ill patients. These beds provide the maximum comfort for the persons or patients as well as the hospital or nursing staff.

However, depending on the degree of immobility of the person using such a bed, it can be cumbersome to get out of bed without help. Because the person must first move to a position in which she sits with the buttocks and possibly the thighs on the side edge of the bed to then get up.

To facilitate getting up from a bed it is off JP-A-2000042053 and US-A-2004/0226093 known to laterally displace the back portion and the seat portion of the mattress overlay relative to the lower leg portion of the mattress overlay, over either one of the two side portions of the bed frame. In the laterally moved-out state of the back part and the seat part of the mattress support device, it is necessary to support the seat surface part or a lateral support of the underframe or bed frame in order to prevent the risk of lateral tilting of the bed.

Out WO-A-2008/087288 . WO-A-2008/090278 and WO-A-2008/087289 It is also known, the lower leg portion of the mattress support device of a bed opposite the back and seat parts of the mattress support device to move laterally beyond the bed frame. Furthermore, it is from the aforementioned writings as well as from DE-A-288 612 and US-A-4,805,246 Known to pivot the lower leg portion of the mattress support device of a bed laterally about a vertical axis relative to the remaining part of the bed or the lower leg part in two parts, both parts are arranged on both sides of the central longitudinal axis of the bed and each articulated about a vertical axis with the remaining part (headboard side Area) of the bed are connected.

Further, it is for example EP-B-0 744 934 known to pivot the lower leg portion of the mattress pad of a hospital or nursing bed down to, as in the aforementioned known beds described above, to be able to get over the foot of the bed out.

Modern hospital or nursing beds have a particular height-adjustable base on which the bed frame is supported and which usually has four legs, which rest on the ground. The headboard-side legs form the headboard-side end of the undercarriage, while the Fußteilseitigen legs define the Fußteilseitigen end of the base frame. These lying in the longitudinal extent of the bed ends of the base must not exceed a certain maximum distance from the headboard or footboard of the bed frame for safety reasons; otherwise there would be a risk that the bed could tip over onto the head or foot part when subjected to vertical loads. The lower leg part of the mattress support device of such beds usually has such a large extent between the foot part of the bed frame and the seat surface part of the mattress support device that the connection plane between the lower leg part and the seat surface part is arranged above the underframe between the two ends. Lower leg parts with such an extension in the longitudinal direction of the bed are comfortable, namely in adults regardless of the size of the person the whole Support lower leg from the knee joint through the lower leg part.

If you move laterally in the previously described known hospital or nursing bed, the lower leg part or pivot in any other way from the rest of the bed, remove or the like, would be to the person lying in bed, the raising from the bed over To facilitate the foot, would be Fußteilseitige areas of the undercarriage still in the way.

Finally it is over JP 03 063329 U . EP-A-0 178 951 and WO-A-2005/027813 known in a bed having a foot, which does not rise up above the lying surface, ie, for example, no upstanding plate or the like. Frame or frames, to move the mattress support device relative to the bed placed over the foot until the lower leg portion of the mattress support device protrudes over the foot and facing down. In this position, the backrest can be raised and tilted the seat part forward, which is the situation like a chair with stand-up help.

Out EP-A-2 181 684 and WO-A-2010/060717 various variations of a bed are known in which the foot can be removed from the remaining part of the bed to get out of the bed with wegbetewet foot of this comfortable or to be able to sit on the bed.

The object of the invention is therefore to provide a bed, in particular hospital or nursing bed, which can be moved in a simple manner in a position in which the raising from the bed and settling in the bed over the foot is easily possible ,

In this bed is provided according to the invention,

• the foot-end-side part and the head-end-side part of the mattress support device can be coupled mechanically by at least one divisible connecting element,
• in that the connecting element has a head end-side first connecting element part, which is arranged on the head-end-side part of the mattress-covering device, and a foot-end-side second connecting-element part, which is arranged on the foot-end-side part of the mattress-covering device,
• in that both connecting element parts have receptacles for a connecting bolt for the mechanical coupling of both connecting element parts, and
• the connecting bolt is movable out of and into the receptacle of at least one of the two connecting element parts.

In the bed according to the invention resting on the preferably height-adjustable base frame bed frame is made in two parts and accordingly divided into a foot-side part and a head-end part or separated. This separation is given in the side parts of the bed frame. Also, the mattress support device is separable into a foot-side part and a head-end part. The mattress support device can be either mechanically connect or disconnect. According to the invention, at least one connecting element which has two connecting element parts is used for this purpose. These two connecting element parts are arranged on the head-end-side part as well as the foot-end-side part of the mattress support device and fastened there in particular as separate parts or as integral parts. The two connecting element parts can be with the help of a connecting bolt, which in aligned with each other the two connecting element parts can dive, mechanically couple with each other. The connecting bolt is thus herausfuhrbar from the recordings or inserted into the recordings.

This configuration of the mechanical coupling of the two parts of the mattress support device can be moved away from each other by a relative movement in the longitudinal extension of the bed or to move toward each other, ultimately to move the foot of the bed away from the rest of the bed. Thus, no lateral shifting or otherwise moving the foot end of the bed (e.g., pivoting about a horizontal or vertical axis) is required. The separability of the connecting element is expediently only possible when the bed frame and bed frame are in their second relative displacement position in which the subdivision level of the mattress support device is in the area between the foot end side of the base frame and the foot end of the bed frame. Then namely the exposed at the foot of the bed removed edge or the then exposed edge of the Kopfendeseitigen part of the mattress support device flush with the foot of the base or projects slightly or even to a greater extent beyond the foot of the base frame. Even a slight Zuruckversetzung this edge or this edge with respect to the foot of the base frame is still tolerable, so that the second relative displacement position can be arranged correspondingly shifted.

The solution according to the invention is characterized by a simple handling, in that the foot end of the bed (in the second relative displacement position of the underframe and bed frame) can simply be removed from the bed or docked in the longitudinal displacement direction.

To stabilize the mechanical coupling of the two parts of the mattress support device, it is expedient if the foot-side part and the head-end-side part of the mattress support device by at least two optionally separable connecting elements according to the invention are mechanically coupled.

It should also be noted that the two connecting element parts of each connecting element in the mechanically coupled state can be rigidly connected or hinged together. If the mattress support device is to be separable in an area in which two of its support parts are connected to one another in an articulated manner, then the connection element separable according to the invention is to be articulated. A separation of the mattress support device within one of its support parts, however, may require a separable connection element which is rigid in the connected state.

In a further advantageous embodiment of the invention it is provided that one of the two connecting element parts of the at least one connecting element has two spaced-apart side projections with mutually aligned receptacles for the connecting bolt and the other connecting element part has a central projection for insertion between the two side projections of a connecting element part and that the central Projection has in its introduced between the two side projections state with the receptacles of the side projections aligned receptacle. Such connecting elements are also known as so-called three-part connecting elements (or "bands"), wherein the two side projections of one connecting element two parts and the central projection of the other connecting element part can be referred to as the third part. Such fasteners are known in particular for hinges.

In order to simplify the coupling of the connecting element parts, it is expedient if either at least one of the two side projections has an internal inclined surface as an import aid or the central projection at least one outer inclined surface as an import aid. With "inboard slanted surface" is an inclined surface on one side of the side projection meant, which opposes the other side projection. The term "outer inclined surface" refers to a side which, in the inserted state of the central projection, faces a side projection of the other connecting element part.

In order to move the connecting bolt or - in the case of the presence of several connecting bolts - all connecting bolts comfortably, it is advantageous if the connecting bolt of the at least one connecting element or in the case of the arrangement of a plurality of connecting elements whose connecting bolt is arranged on a linkage /, wherein the Linkage manually or automatically between a locking position in which each connecting bolt locks the two connecting element parts of the respective connecting element, and a release position is movable in which each connecting pin releases the two connecting element parts of the respective connecting element.

As described above, it is provided according to the invention that the bed frame is divided. As long as the bed frame and the base frame are not in the second relative displacement position, both parts of the bed frame are supported by the base frame. In the second relative shift position, the foot end of the bed, that is, the foot end side part of the bed frame and the foot end side part of the mattress support device, which in turn is supported on the foot end side part of the bed frame, rests on feet on the ground on which the underframe is also positioned. In this regard, it is useful if the Fußendeseitige part of the bed frame is supported on at least three feet. The three feet are not arranged along a common straight line, but form, for example, the corners of a triangle. Conveniently, the support of the Fußendeseitigen part of the bed frame over four feet, which ensures the stability of the resting of the foot end of the bed on the ground. For this reason, the two bed frame parts also need in the second relative displacement position not mechanically coupled with each other. However, this can be provided if desired.

The starting point of the invention is therefore a bed with a bed frame, which has two side parts on the lateral sides, a head end possibly with a head part and possibly a foot part with a foot end. Supported on the bed frame is a mattress support device which is formed in three or four parts and adjustable. The mattress support device has at least one adjustable back part and an adjustable lower leg part and between them a fixed or movable or partially movable seat part. According to an advantageous development of the invention, the seat part can have two parts, namely a thigh part and a seat or seat part. The thigh part is suitably adjustable and hinged to the seat part.

The bed frame is supported by a subframe, which is delimited in the longitudinal extent of the bed by a foot-side and a head-side end. In general, the base rests on head and foot support means on the ground. The subframe can be moved, i. be equipped with roles, but this is not mandatory. Furthermore, the base can be conveniently adjustable in height.

In a normal nursing bed, neither the bed frame nor the mattress support is divided such that a part of the bed frame can be moved away from the remaining bed frame part or part of the mattress cover from the remaining part of the mattress cover. However, this is now possible according to the invention by both the mattress support device and the bed frame along each of a subdivision levels in each case in a Fußendeseitigen part and in a Kopfendeseitigen part are separable or separated. The two subdivision levels, to the two sides of the head and Fußendeseitigen parts (hereinafter also referred to with head or Fußteilseitigem part) are arranged, can collapse or run parallel with a small distance.

Furthermore, according to the invention, the above-mentioned Relativverschiebungsmöglichkeit between bed frame and base is provided. When the hospital bed is used as a normal bed, the bed frame and underframe are in a first relative shift position. In this first relative displacement position is the subdivision level of the mattress support device (and usually the subdivision level of the bed frame, which in the invention thus be spaced apart or may coincide) in the area between the foot and headboard side ends of the underframe, order now wegbewegten Fußendeside It is provided in accordance with the invention to move the bed frame and underframe relative to each other to the second displacement position in which the subdivision plane of the mattress overlay device (and optionally also the subdivision plane of the bed frame) can be easily disembarked from bed or seated ) is outside the area occupied by the base. In this case, the position of the seat surface part is such that now no areas of the foot part side end of the bed are now up to get out of the bed Base frame are more in the space below the lower leg part facing the front edge of the seat part, which requires the bed leaving or sitting in the bed person.

In other words, in the second relative shift position, the subdivision plane of the mattress support device is substantially aligned with the foot part end of the undercarriage. In this case, "substantially in alignment" means that the subdivision plane is directly above the footpart end of the undercarriage or slightly before it or slightly located behind this. When placed in front of the Fußteilseitigen end of the base frame, the subdivision level of the mattress support device between the Fußteilseitigen end of the base frame and the foot part of the bed frame, while the subdivision level of the mattress support device in the position behind the Fußteilseitigen end of the underframe between this Fußteilseitigen end and the headboard end of the Underframe is located.

There are various ways to move the Fußteilseitige parts of mattress support device and bed frame together so relative to the rest of the bed that the exit from the bed on the (now standing in the way) foot of the bed is possible. In order to rise from the bed, the back and seat portions may be placed in a chair-like position, whereby the seat portion may be tilted slightly upwardly to further assist in erecting to support the lower legs in the popliteal region. In addition, can be inclined by tilting the bed frame forward as a further stand-up of the thus forming chair or chair. Such stand-up aids are basically known from chairs or armchairs ago. What is new, however, is the integration of these stand-up aids in a conventional bed. The Fußendeseitigen parts of mattress support device and bed frame according to the invention (after unlocking the at least one connecting element) can move away from each other easily (in the longitudinal direction of the bed).

It is useful if the Fußendeseitige part of the bed frame has its own support to the ground on which rests the entire bed has. Such debris can be legs with casters that facilitate movement of the foot-end portions of the mattress overlay and bed frame over the ground. The support of the Fußendeseitigen part of the bed frame acts in a height-adjustable base frame in particular when the

Underframe is located at its minimum height. The support of the Fußendeseitigen part of the bed frame relative to the ground is particularly useful when taking the second relative displacement position of the bed frame and base. If the bed or if the bed frame and the base occupy a different relative displacement position, so the support elements or the support can also be repealed, which can be done for example by folding or removing the support.

For safety reasons, it is expedient if the bed according to the invention can only be raised when equipped with a height-adjustable underframe when the bed frame and underframe occupy the first relative displacement position. Then namely the bed frame is supported with maximum stability on the ground, since the base is arranged substantially centrally under the bed frame. In other words, the height adjustability of the underframe is released only in the first relative shift position of bed frame and base. In other words, the longitudinal displaceability of the bed frame and underframe can then be realized only when the underframe is essentially at a minimum height. This statement is also intended to cover the case that the base can be slightly raised in the second relative position of displacement of the bed (and thus completely removed foot-side parts of mattress support device and bed frame), in such a way that the seat part on one of chairs and armchairs ago known "comfortable" height to get up from the bed and settling on the bed.

Due to the division of the bed frame whose side parts are each formed in two parts and divided into a fußteilseitigen and a headboard side section. For stiffening these side parts of the bed frame in any other than the second relative displacement position of the bed is advantageously a stiffening element which extends on both sides of the subdivision level of the bed frame and in the two sections of the respective side part submerged when the bed frame and subframe occupy a position other than the second relative position. The stiffening elements can be manually operated and thus manually movable. Alternatively, the stiffening elements may also automatically disengage from the two footboard side portions of the side panels of the bed frame when the bed frame and underframe occupy their second relative translational position. For this purpose, the stiffening elements are arranged fixed relative to the base frame (or to the bed frame), which depends on whether the base frame can be actively moved relative to the bed frame or the bed frame relative to the base frame.

Conveniently, the stiffening elements are each formed as a bolt, wherein a receiving channel for receiving the bolt is arranged at both portions of each side part of the headboard side bed frame part respectively a guide channel for guiding the relevant bolt on the fußteilseitigen portion of the side part and wherein the bolts during the relative displacement of the bed frame and Underframe are arranged in the guide and receiving channels and are in the second relative displacement position outside the receiving channels,

So that the Fußendeseitige bed frame part can not be moved unintentionally relative to its Kopfendeseitigen section when bed frame and base are in their second relative displacement position, it is expedient to provide a locking element which is in particular manually operated and unlock to move the Fußendeseitige bed frame part can .

The connection between the (respectively) head and Fußendeseitigen parts of the mattress support device and optionally the bed frame is advantageously carried by joints, the joint axes expediently but not necessarily substantially parallel to the subdivision planes and parallel to the ground (ie, usually horizontal).

The axis of the joint between the two parts of the mattress support device expediently extends above the side parts of the bed frame.

As already briefly mentioned above, the lower leg part of the mattress support device is pivotally connected to the seat part. If the seat part itself is in two parts and has a thigh part and a seat or seat part, the articulated connection between the lower leg part and the thigh part takes place. The lower leg part rests on the Fußteilseitigen part of the bed frame and is taken when moving the Fußteilseitigen part of the bed frame of this. The lower leg part can be lifted up with entrainment of the thigh part or the seat part and supported in a raised position on so-called support plate. The support plates are expediently designed as a support stand scissors having two transverse to the side parts of the bed frame, intersecting struts, which are slidably and rotatably connected at their ends with the fußteilseitige parts of mattress support device and bed frame and selectively lockable in one of several intersecting inclinations , The transversely mounted Stützstellerschere gives the fußteilseitigen parts of the bed frame and mattress support device a shear-resistant and shear strength connection. Examples of backing plates that can be used for the bed according to the invention are in DE-A-16 54 383 and DE-A-15 54 117 described.

As also already mentioned above, the bed frame can be displaceably mounted on the underframe for transferring the bed from the first relative shift position to the second relative shift position or else the lower frame can be displaceably mounted on the bed frame. In the second case, the base is expediently made variable in length, so it is based on a parallel to the ground (horizontal) plane telescopic. The headboard-side end of the underframe is expediently connected to displacements relative to the bed frame with this, whereas its footboard end is longitudinally slidably coupled to the bed frame. Starting from the first relative displacement position, the underframe is then contracted or contracted, so that, finally, in the second relative displacement position, the footpart end of the underframe substantially aligns with the subdivision plane of the mattress support device (in the stated sense or above).

The Abrückbarkeit invention of the Fußteilseitigen section (hereinafter called foot) of the bed described above is not readily feasible insofar as both the bed frame and the mattress support device must be divided accordingly. As regards the mattress support device, its relative displaceability between the lower leg part and the thigh part (i.e., the seat part) which may be combined with the seat surface part lends itself to this. These two parts are usually hinged together, the thigh part is particularly motorized pivot, with the result that the articulated lower leg part "dragged" is. The lower leg part is thus raised at pivoting of the thigh part in the region of the joint to the lower leg part.

In a variant of the invention, this articulated connection is now deliberately notched or otherwise released in order to move the foot end of the bed away from the remaining part of the bed (in its direction of longitudinal extension). During the subsequent shifting back of the foot end of the (possibly articulated) connection is restored, which improves the ease of use.

The advantage of the construction according to the invention, in which it is generally provided that the foot of the bed frame can be at least partially moved away, is the fact that the person lying in bed can now stand up much easier. Because after taken away foot takes the person lying in bed with appropriate Hochverschwenkung the backrest portion of the mattress support automatically a seated position.

Representations of a bed in plan view with alternatively separable fastener arrangement.

In the FIGS. 1 to 16 schematically a hospital or nursing bed 10 is shown, which can optionally be used as a chair or chair, wherein the pivotable back part of the mattress support device forms the back of the chair.

The bed 10 has a base 12 which is height adjustable. The base 12 is provided with four legs 14,16 (usually with lockable rollers), which are telescopically or otherwise adjustable in height and at their upper ends by connecting elements 18th (see also the FIGS. 5 and 6 ) are interconnected. The headboard-side legs 16 form the headboard-side end 17 of the undercarriage 12, while the Fußteilseitigen legs 14 define the Fußteilseitige end 15 of the undercarriage 12.

On the height-adjustable base 12, a bed frame 20 is mounted horizontally displaceable. The bed frame 20 comprises at the head end 21 of the bed 10, a head part 22 and at the foot end 23 of the bed 10, a foot part 24, the head part 22 and the foot part 24 are interconnected by two side parts 26. The two side parts 26 are slidably mounted on the upper end of the undercarriage 12. For an automatic displacement of the bed frame 20 relative to the base 12, a motor 28 is used; but the shift can also be done purely manually (ie without motor).

In the bed frame 20 a (four-part) mattress support device 30 is arranged, which has a pivotable back part 32, a fixed seat part 34, a pivotable thigh part 36 and a movably arranged lower leg part 38, wherein alternatively the thigh part and the seat part also to a common, adjustable seat part may be summarized, as is the case with three-piece mattress support devices. The lower leg part 38 is pivotally connected to the upper leg part 36 and is moved along pivoting of the thigh part 36 (see the arrow 40), wherein it is raised at its (connecting) end facing the thigh part 36 and thus inclined. The pivotability of the back part 32 is in Fig. 1 indicated by the arrow 42.

A special feature of the bed according to the FIGS. 1 to 16 is in the division of the bed frame 20 and the mattress support device 30 in the area in the FIGS. 9 and 10 vertical subdivision levels 44 and 45 can be seen. On both sides of the subdivision plane 44 is now per side part 26 of the bed frame 20, a headboard side portion 26a and a fußteilseitiger portion 26b. The two resulting bed frame parts, namely the Headboard-side bed frame part 20a and the foot part side bed frame part 20b are in the longitudinal extension of the bed 10 away from each other and to each other to move. Also, the mattress overlay device 30 is divided by the partition plane 45 into a head part side part 30a and a bottom part side part 30b. In this embodiment, the headboard side portion 30a of the mattress overlay apparatus 30 includes the back portion 32, the seat portion 34, and the thigh portion 36, while the footboard side portion 30b of the mattress overlay apparatus includes the lower leg portion 38. The division can also be made differently. It should be noted that the two subdivision planes 44 and 45 may be offset or coincident with each other.

The aforementioned removability of the footboard side bed frame part 20b makes it possible to use the bed 10 like a chair to get out of the bed 10 and sit down on the bed 10, respectively. In normal use, the bed 10, as in Fig. 1 If one were to move in this state of the bed frame 20, the Fußteilseitigen part 20b of the bed frame 20, so would areas of the base frame 12, namely the Fußteilseitigen legs 14, obstructive. Therefore, the bed frame 20 can be compared with the base frame 12 (with reference to the illustration in FIG Fig. 1 ) are moved horizontally until the dividing plane 44 is outside the area occupied by the undercarriage 12 (see Fig. 2 ).

The position and setting of the bed 10 to use the same as a chair or chair as a stand-up is in the FIGS. 13 to 15 shown. It can be seen that the mattress lying on the mattress support device 46 is made in two parts and includes a headboard-side portion 48 and a Fußteilseitigen section 50. The Fußteilseitige section 50 rests on the lower leg portion 38 of the mattress support device 30, while the headboard-side portion 48 of the mattress 46 rests on the back part 32, the seat part 34 and the thigh part 36 of the mattress support device 30 and by Einfasselemente 47 against slipping to the foot end 23rd of the bed 10 is secured. The lower leg part 38 is provided with two safety side parts 52, which in the FIGS. 1 and 2 are shown in the erected position in which they protrude laterally of the mattress 46 over the top thereof. Furthermore, in Fig. 14 two armrest parts 54 and 55 are shown, which in this embodiment is fixed to the bed frame 20, namely at its side part portion 26a (for example, by plugging or the like removable attachment). The armrest part 54 can be different than in this case Fig. 14 shown extending substantially straight up, while the armrest part 55 extends from the Bettrahmenseitenteil initially over the mattress 46 (or slightly angled up) to about the center of the seat and from there further upwards. The back part 32 of the mattress support device 30 has two safety side parts 56. As based on Fig. 15 can be seen, now when getting up from the bed 10, the armrests 54 and 55 as the armrests of a chair can be used to support when putting on and off.

In the FIGS. 1 to 12 It can also be seen that the removable foot end 23 of the bed 10 is supported by legs 58 with rollers 60. This is not mandatory according to the invention, but facilitates the Abrückbarkeit the foot end 23 relative to the rest of the head end 21 of the bed comprehensive bed frame 20. The legs 58 may be designed to be folded or removable. They support the foot end 23 automatically when it is not connected to the rest of the bed 10 (see, eg FIGS. 13 and 14 ).

The FIGS. 5 to 14 illustrate in detail how the connection or separation of both sides of the subdivision levels 44 and 45 are located parts of the bed 10 is realized. According to the invention, the thigh part 36 of the mattress support device and its lower leg part 38 are connected to one another in this embodiment by at least one, in this embodiment, two separable joints. For this purpose, each joint has a connecting part 62 which has two connecting element parts 64, 66. The first connector part 64 is disposed on the femoral portion 36 in this embodiment, while the second connector portion 66 is attached to the lower leg portion 38. The first connecting element part 64 has a central projection 68 with a passage opening or receptacle 70 extending transversely to the longitudinal extent of the bed. Each second connecting element part 66 has two side projections 71, between which there is a free space 72 into which the central projection 68 of the first connecting element part 64 can dip. The two side protrusions 71 are also provided with through holes 74 which are aligned with the receiving opening 70 of the central protrusion 68 of the first connecting member part 64 when the central protrusion 68 is located between the side protrusions 71. By the mutually aligned receptacles 70 and 74 of the two connecting element parts 64,66 can be a connecting pin 75 introduce, so that the two connecting element parts are hinged together. The connecting pin 75 can be moved axially, ie along the axis 76, so that the two connecting element parts 64, 66 are either connected to one another via the connecting pin 75 or are separated from one another.

It can be seen in the figures that the connecting bolts 75 of the two connecting elements 62 can be unlocked and locked together. For this purpose, both connecting pins 75 are located on a linkage 77, which has an actuating rod 78 with actuating button 79. This actuating rod 78 is guided displaceably on a guide 73, as shown in particular with reference to the Fig. 8 can be seen.

As based on the FIGS. 5 to 14 Further, the central projection 68 of each first connector element portion 64 has external slant side insertion surfaces 69 which facilitate insertion of the central projection 68 between the side projections 71 of the second connector element 66. Alternatively, at least one of the two could Side projections 71 have an inner sloping side surface. This would also act like an introduction aid.

In the FIGS. 1 to 12 It can also be seen that the lower leg part 38 can be supported at its end facing the foot part 24 of the bed 10 via a sliding or roller element 80 on the sections 26b of the side parts 26 of the bed frame part 20b. In this case, this support takes place on the inner sides of the portions 26b of the bed frame 20. As a result, the lower leg portion 38 is guided on the bed frame 20, in particular when the foot end 23 is moved laterally. Then namely the lower leg part 38 is automatically taken. Lower leg part 38 and the bed frame part 20b of the foot end 23 of the bed 10 can thus always move together laterally, even if the force required for the displacement is exerted only on one of these two parts. A scissors-type high-rise construction 82 (scissors support in the FIGS. 5 to 7 indicated) is arranged transversely to the longitudinal extent of the bed 10 between the bed frame part 20b and mattress support device part 30b. This horseshoe construction 82 ensures a shear-resistant connection of lower leg part 38 with the foot part side bed frame part 20b.

When booting the bed frame 20 by the height-adjustable frame 12 should be prevented that the foot end 23, when it is no longer supported on the roller 60, can unintentionally fold down. This can be realized by a bolt 84 provided as a stiffening element 86. In each side part 26 of the bed frame 20, such a bolt 84 may be arranged, which is received by both side portions 26 a and 26 b, when the bed is not in its displaced position according to Fig. 2 , eg in the shift position according to Fig. 1 (see also the detail drawings according to FIGS. 9 and 10 ). These stiffening elements 86 reinforce the connection between the two sections 26a and 26b of each side part 26 of the bed frame. They are connected to the base 12 and lie in guide channels 88 of the headboard side sections 26a of the side parts 26. In the normal sliding position of the bed (see FIGS. 1 and 9 ), they are immersed in receiving channels 90 of the foot portion side portions 26b of the bed frame side members 26, while being moved out of the receiving channels 90 in the position of the bed for laterally displacing the foot end 23.

The following is again with reference to the FIGS. 1 to 12 will be discussed in more detail on the operation and operability of the bed 10.

Basically, the Relativverschiebbarkeit of base frame 12 and bed frame 20 is only possible when the height-adjustable base frame 12 is in its minimum height position, as in Fig. 1 is shown. The reaching of this position is detected by one or more detectors (for example, limit switches, not shown). In this situation, the foot end 23 of the bed 10 is supported by the legs 58 and rollers 60. The bed, as in the FIGS. 3 and 4 shown, optionally in the shock position (Trendelenburg position) according to Fig. 3 or in the anti Trendelenburg position ( Fig. 4 ) are transferred.

Now, if the bed 10 to be prepared in the position for exit from the bed at the foot end, so first the mattress support device 30 can be transferred to the appropriate position by the back part 32 is raised and possibly the thigh part 36 slightly inclined, as shown in the FIGS. 13 to 16 is shown.

To move the foot end 23 in the direction of longitudinal extent of the bed 10, the bed frame 20 must first be moved relative to the underframe 12 in the longitudinal extension of the bed 10, starting from the normal position according to FIG Fig. 1 the position according to Fig. 2 is reached. This position is detected by a detector 94. In this position (second longitudinal displacement position), the stiffening members 86 provide the foot portion side portions 26b of the side parts 26 of the bed frame 20 free, as also by a comparison of FIGS. 9 and 10 can be seen. The FIGS. 5 to 8 show the top views of the bed 10 in the normal position (first longitudinal displacement position according to FIG Fig. 5 ) and the second longitudinal displacement position according to Fig. 7 , In Fig. 7 is indicated by the arrow 96 that now the unlocking of the connecting elements 62 can be made by pulling on the operating knob 79. The resulting displacement of the linkage 77 and the associated unlocking of the connecting elements 62 is in Fig. 7 indicated. Based on the situation according to Fig. 7 can now the foot end 23 in the longitudinal direction of the bed 10 (see the arrow 97) are moved away. Thus, the situation then follows according to Fig. 8 (see also the FIGS. 13 to 15 ).

The position of the foot end 23 in the state connected to the rest of the bed according to Fig. 5 is detected by a detector 98. Once this detector does not indicate the receipt of the connection position of the foot 23 with the bed 10, the adjustment of the base 12 is only possible up to a slightly above the minimum height height (a few centimeters), namely the bed converted into a chair or chair to be able to lift to a comfortable seat height. The further height adjustment of the undercarriage 12 is prevented, since otherwise the foot 23 would no longer be supported by its legs 58 and thus tilt the raised bed at vertical loads on the foot 23 and in the worst case, the foot 23 of the bed could break off. In that regard, therefore, upon detection of the second longitudinal displacement position according to Fig. 2 limited by the detector 94, the height adjustment of the undercarriage 12 to the just described slight adjustment.

Further, in the chair position of the bed 10 according to FIGS FIGS. 13 to 16 still an inclination of the headboard side bed frame part 20a possible (see Fig. 16 ), which serves to further facilitate getting up.

In the FIGS. 17 to 19 is schematically shown in plan view a second embodiment of the invention separable fasteners. As far as the individual components of these fasteners construction or functionally identical to the individual components of the connecting elements 62 of the bed according to the FIGS. 1 to 16 are, they are in the FIGS. 17 to 19 with the same reference numerals as in the FIGS. 1 to 16 characterized.

The main difference between the two fastener embodiments of FIGS. 1 to 16 on the one hand and the FIGS. 17 to 19 on the other hand, is that in the FIGS. 17 to 19 both connecting element parts 64,66 are formed as single projections or -Bläläge, which are laterally adjacent to each other when the connecting pins 75 are inserted through the then aligned receptacles 70 and 74. Otherwise, the locking and unlocking function (with optionally incorporated detection by the detector 98) is identical to that previously in connection with the FIGS. 1 to 16 Said.
