Definitions
- the present invention relates to a bed comprising a relatively rigid bedstead bottom and at least one resil- ient layer arranged thereon.
- the invention relates to an adjustable bed of the type where the bedstead bottom in the longitudinal direction of the bed is divided into at least two segments which are articulated to one another, and with adjusting means for adjusting the angle between the segments.
- adjustable beds of the type where the bedstead bottom in the longitudinal direction of the bed is divided into two or more segments which are articulated to one another, where the angle between the segments can be adjusted as desired by the user.
- the bed can be easily adapted for different purposes, such as sitting in when reading, working, eating etc., lying on when sleeping or resting, placing one's legs or head high in connection with certain disorders and illnesses, etc.
- EP 0604240 These known beds comprise four segments which can be arranged at various angles relative to one another by means of adjusting means.
- one problem with these prior-art constructions is that the construction which allows adjustability makes it more difficult to insert other types of comfort, such as massage devices.
- one problem is that there is often A conflict in making a bed comfortable in both the outer posi- tions, i.e. in a sitting position and in a lying down position. Since the lying down position has to be given priority, this means that the bed does not become as comfortable to sit in as furniture directly adapted for this position.
- An object of the present invention is thus to provide a bed which wholly or at least partly solves the above-mentioned problems of prior-art technique and, thus, provides a more comfortable and/or less complicated bed construction.
- a bed which comprises a relatively rigid bedstead bottom and at least one resilient layer arranged thereon and at least one part which is movable relative to the bedstead bottom for local variation of the hardness and/or the height of the resilient layer, which movable part is articulated to the bedstead bottom and is lockable in different positions which are raised relative to the hinge.
- This construction provides a bed where the hardness of the bed can be locally increased, which is useful especially to provide an improved curve support.
- the movable part obtains support and stability from the bedstead bottom, which renders it possible to make the construction simple and inexpensive at the same time as it is rugged and durable.
- This is especially suitable for adjustable beds, where a simple and light construction is particularly preferred.
- the bed comprises a displacement means for automatic displacement of the movable part between different raised positions, which displacement means preferably acts against that side of the movable part which is opposite to the resil- ient layer. Owing to the stable construction of the movable part, both the displacement means and the connection between the same and the movable part can be made easily and inexpensively since relatively low loads are provided.
- the movable part has a surface which is convex towards the resilient layer and, above all, that the convex surface has a bend which increases in a direction away from the articulated connection between the movable part and the bedstead bottom. This causes a relatively even increase of the load even when the movable part is in a raised position.
- it comprises a bed having a relatively rigid bedstead bottom and at least one resilient layer arranged thereon, and at least one massage device comprising a vibration unit which via a vibration retarding connection is connected to the bedstead bottom on that part of the same which is opposite to the resilient layer, and vibration transmitting means connecting the vibration unit to the part of the resilient layer that is opposite to the bedstead bottom.
- the vibration retarding connection preferably comprises distance elements of vibration absorbing material, preferably of rubber material .
- the vibration transmitting means preferably comprise a relatively inelastic and preferably bendable connecting means, such as straps.
- two or more massage devices which preferably are adapted to produce vibra- tions with different frequencies, and further preferably are separated from one another, and preferably separated in the longitudinal direction of the bed.
- interference between the vibrations which are transmitted from the massage devices results in massaging vibrations being obtained also between the massage devices, which makes the massaging effect more efficient .
- a bed is especially preferred having a combination of the above-mentioned aspects of the invention.
- the two above-mentioned aspects of the invention are each separately, or in combination, particularly suited for beds of the type where the bedstead bottom in the longitudinal direction of the bed is divided into at least two segments which are articulated to one another, and adjusting means for adjusting the angle between the segments.
- the two above-mentioned aspects of the invention are each separately, or in combination, especially suited for beds where the resilient layer com- prises at least one layer of elastic springs.
- FIG. 1 is a partly cross-sectional perspective view of a bed according to one embodiment of the invention, the adjusting means not being shown,
- Fig. 2 is a partly exploded cross-sectional side view of the bed in Fig. 1 in a first, lowered position
- Fig. 3 is a partly exploded cross-sectional side view of the bed in Fig. 1 in a second raised position
- Fig. 4 is a cross-sectional perspective side view of a curve support according to one embodiment of the invention shown in a lowered position
- Fig. 5 is a cross-sectional perspective side view of the curve support in Fig. 4 shown in a raised position
- Fig. 6 is a cross-sectional perspective side view of a massage device according to one embodiment of the invention.
- a bed according to a preferred embodiment of the invention as shown in Figs 1-3 comprises a bed frame 1 which supports a bedstead bottom 2. At least one resil- ient layer 3, preferably an elastic spring layer, is arranged on the bedstead bottom.
- Bed constructions without a separate bed frame, where the bedstead bottom is self- supporting, are, however, also possible.
- the aspects of the invention are especially suited for adjustable beds, but are also usable in a large number of other conventional bed types.
- the bedstead bottom is as shown in Figs 1-3 divided into segments, preferably four segments, in the longitudinal direction of the bed: one headboard segment 21, a base segment 22, an upper footboard segment 23 and a lower footboard segment 24. These segments are adjustable in such a manner that the headboard can be raised rela- tive to the base segment as a back-rest, and so that the lower footboard segment can be raised.
- an adjusting means 4 for adjusting the inclination between the headboard segment and the base segment comprises a pivot pin 41 ex- tending in the transverse direction of the bed.
- the pivot pin is affected directly, or preferably via one or more link arms, by a piston assembly 42.
- Other ways of auto- matically or manually rotating the pivot pin 41 are also possible .
- the pivot pin further comprises rigid protruding arms 43 which abut against a sliding surface 44 of the headboard.
- the arms 48 thus press the headboard segment 21 upwards.
- rolls 45 or the like can be arranged at the end of the arms which abut against the bedstead bottom in order to thus further reduce the friction.
- an adjusting means 5 for the upper and lower footboard segments comprises a pivot pin 51 extending in the transverse direction of the bed.
- the pivot pin is affected directly, or preferably via one or more link arms, by a piston assembly 52.
- Other ways of automatically or manually rotating the pivot pin 51 are also possible.
- the pivot pin comprises rigid protruding arms 53 which abut against a sliding surface 54 of the upper footboard segment.
- rolls 55 or the like can also be arranged at the end of the arms which abut against the bedstead bottom in order to thereby reduce the friction further.
- link arms 56 are arranged between the bed frame and the lower footboard segment below the pivot pin. By rotating the pivot pin 51, the arms 53 thus turn the upper footboard segment 23 upwards, whereby the lower footboard segment 24 is raised.
- adjusting means are possible as is known within the field of the invention.
- other drive means instead of piston assemblies can be used;
- other transmitting means instead of the link arms and the like that have been described above can be used, etc.
- the adjustable bed as described above can also be equipped with means for displacing the bedstead bottom 2 relative to the bed frame 1 when raising the headboard segment 21, so that the distance in the longitudinal direction of the bed between the headboard segment 21 and the headboard of the end of the bedstead during raising remains constant or at least is not changed to any appreciable extent.
- This can be provided by the adjusting means and the bedstead bottom together being displaceably connected to the bed frame.
- the bedstead bottom and the adjusting means can be arranged on two bars 81 extending adjacent to the bed frame and essentially parallel to the longitudinal direc- tion of the bed. These bars are in a slidable manner connected to and supported by the bed frame 1 via attachments 82 in the bed frame.
- roller bearings 83 or the like can be arranged between the attachments 82 and the bars 81.
- that part of the bed which is displaceably arranged relative to the bed frame is advantageously connected to the headboard of the bed frame via a link arm system 84, which preferably is connected to the pivot pin 41. Consequently, the displaceable part of the bed is automatically pulled towards the headboard of the bed when the head end is raised.
- the bed is advantageously equipped with covering means 12 which are arranged between the bed frame and at least one of the movable segments.
- the covering means are intended to cover the gap which is formed between the segment of the bedstead bottom and the bed frame when the segments are in the raised position.
- such covering means can advantageously be ar- ranged in the footboard and/or headboard of the bed as in the preferred embodiment.
- the covering means comprise textile material which is extensible and has a tensioning function which automatically tightens slackening parts of the material . This can be provided, for ex- ample, by the material in one end being wound on a spring-loaded roll 13, where the spring acts to wind the material on the roll . Covering means as mentioned above reduce the risk of injury caused by squeezing and the like. Besides, the bed becomes more aesthetically attractive.
- the bed according to the invention also comprises at least one part 6 which is movable relative to the bedstead bottom for local variation of the hardness and/or the height of the resil- ient layer 3 by varying the distance between the bedstead bottom 2 and the resilient layer.
- the movable part 6 is articulated to the bedstead bottom via a pivot pin 61, such as one or more hinges.
- the pivot pin 61 is arranged in the transverse direction of the bed.
- a movable part can be arranged in a position corresponding to the curve portion of the person lying down and, thus, function as a curve support. This is particularly important when the bed is used to sit in.
- portions with the pur- pose of varying hardness and height can, however, be arranged also at other locations in the bed.
- the movable part is lockable in different positions which are raised relative to the hinge.
- This is preferably provided by displacement means 62 for automatic displacement of the movable part between different raised positions, which displacement means also retains the movable part in the position taken.
- the displacement means can advantageously be a piston assembly, but other variants, such as an electric motor or the like, are also possible.
- the displacement means 62 acts against that side of the movable part which is located opposite to the resilient layer, and also advantageously articulated to the movable part via a pivot hinge 63.
- the movable part is advantageously formed with a convex surface 64 facing the resilient layer in order to allow easy and at the same time comfortable raising of the resilient layer.
- the convex surface 64 is suitably bent in the longitudinal direction of the bed, and perpendicular to the pivot pin of the movable part.
- it is preferred for the convex surface to have a bend which increases in a direction away from the articulated connection between the movable part and the bedstead bottom, so that those parts which during pivoting of the movable part are moved the most have the largest radius of curvature.
- the movable part can be made of a plate of, for example, sheet metal or a hard plastic material .
- Fig. 6 shows that the bed according to the invention further comprises a massage device 7 having a vibration unit 71.
- the vibration unit can be an electric motor that drives an unbalanced rotating body, and can further advantageously be encapsulated in a casing.
- other vibration units can also be used and are already known within the field of the invention.
- the vibration unit 71 is connected to the bedstead bottom 2 via a vibration retarding connection.
- This connection can, for example, comprise distance elements 72 of rubber or some other vibration absorbing material.
- the vibration unit is fixedly arranged on a plate 73 which, in its turn, via the distance elements 72 is attached to the bedstead bottom 2.
- the vibration unit is further directly or indirectly connected to vibration transmitting means 74 which transmit vibrations from the vibration unit to that part of the resilient layer 3 which is opposite to the bedstead bottom.
- the vibration unit is preferably arranged at the opposite side of the bedstead bottom, the vibration transmitting means being extended through openings 75 in the bedstead bottom or extended past the same in some other suitable manner.
- the vibration transmitting means can be a relatively inelastic and preferably bendable connecting means, such as a strap 74 of a relatively inelastic material.
- the massage device preferably comprises at least two such transmitting means.
- the straps are thus at one end attached to the vibration unit 71 or to the supporting plate 73, and extend through the openings 75 in the bedstead bottom. At the other end, they are attached at one or more points in the resilient layer, preferably at a height corresponding to at least half of the resilient layer, and most preferably in the surface layer of the same.
- the vibration transmitting means can advantageously be pretensioned or comprise tightening means with the purpose of avoiding slacking when the resilient layer is compressed when in use.
- the massage device as described above can advantageously be arranged in the middle of the bed, for example adjacent to the base segment 22 of the bedstead bottom.
- massage devices in other positions of the bed, and it is especially preferred to use at least two massage devices. Consequently, by being adapted, for instance, to produce vibrations at different frequencies, the massage devices can give a massage effect not only in their direct positions but also therebetween due to the interference phenomenon.
