"Multi-Position Bed"
This invention relates to a multi-position bed such as is used in hospitals and for persons who by reason of physical disability or age are unable to turn or move themselves in bed. Moving such persons manually at frequent intervals is a time consuming and physically tiring activity for the nurse and hence multi position beds have been produced which have the facility for turning a patient and also for tilting in various directions.
An object of the present invention is to provide a multi position bed which has many different functions but is compact and simple to operate.
According to the invention a multi-position bed comprises a base frame carrying a mattress p~latform whic~ -is pivote~ at ~its ends;~ on-pivot brackets carried on a -base frame, for lateral tilting, the platform comprisinga centre section and two side sections, the side sections being connected at their ends by links to end pivot frames on the centre section and being connected at intermediate points through pairs of links to a pivot bracket whereby lateral tilting of the centre section in either direction causes a side section to tilt in the other direction to produce a turning effect on a patient.
Preferably the side sections and centre sections have interengaging features along their adjacent edges which only engage when the centre section is in its non (later-ally) tilted position, but automatically disengage when lateral tilting of the centre section takes place.
Preferably the pairs of links are easily disconnectable and one link of each pair may then be used as a strut to rigidify the connection between each side section and the centr!e section so that when the centre section is laterally tilted it carries with it both of the side sections so that all three sections remain planar and tilt together.
' Preferably the lateral tilting movement of the centre section is produced by a screw and nut mechanism.
The screw may be driven by an electric motor carried on the underside of the centre section and the n-lt may be mounted on one of the pivot brackets.
From another aspect a multi position bed comprises a base frame on which is pivoted a matt~ss platfo~for later~
tilting movement, the mattress platfonm c~rising a c~ss section and two side sections, the centre section being pivoted on pivot brackets below the mattress platfom and the side sections being connected to the pivotbracket by links, the arrange-ment being such that with the links in place when the centre section is pivoted laterally in either direction the side section separates and pivots in the other direc-tion so as to produce a turning movement of the patient, the links being disconnectable and the side and centre sections being capable of being rigidified so that when the centre section is tilted the bed frame as a whole tilts laterally without any separation of the side sections.
Preferably at one end of the bed the centre and side sections both have pivoted end portions which may be raised together to provide an uplifting backrest.
The side sections and centre sections are preferably separately pivoted but so arranged that~when the centre section is lifted~laterally projecting lifting plates onthe centre section will engage corresponding laterally projecting lifting plates on the side sections so that all three sections lift together, When the bed is used in its turning mode the side sections separate from the centre section because the lifting plates are not attached to each other.
Preferably the pivot brackets on which the centre section is pivoted are themselves carried by lifting arms at each end of the bed, the arms being pivoted onthematt~ss ~Z471~
~.
platfonn. These arms may be operated by screw jacks in turn operated by electric motors so that the ~attress platform may be raised and lowered bodily or maybe tilted longitudinally at will.
Preferably the lifting arms axe operable by nut and screw mechanisms, there being two such mechanisms each operated by an electric motor so as to provide independent movement of the arms to enable the bed to be tilted.
The movement of these arms may be assisted by gas struts so as to relieve the load on the motors and the gas struts may be located longitudinally on or beneath the base frame.
The base frame may be carried on caster wheels in conventional manner and the caster wheels may have braking facilities.
The centre sectlon of the mattress platfonT may have a hlnged flap, for toilet purposes, and the flap may have combined hinges and catches at each side so that removal of the catches at one side enables the flap to be pivoted about its other side and vice versa. This enables the flap to be opened from either side of the bed at will.

As shown in Figures 1 to 5 of the drawings the bed comprises a base frame 1 supported on casters and having a pair of pivoted angled lifting arms 2. One of the pair of lifting arms is pivoted in turn to an interlink 3 pivoted to a pivot bracket 4. The other lifting arm 2 is pivoted directly to a pivot 5.
The pivot brackets 4 and 5 (best seen in Figures 3 and 4) act as the pivot supports for the centre section 6 of amattress platform which is (as seen best in Figure 1) also comprises two side sections 7. The side sections 7 are not hinged directly to the centre section but simply have interengaging features in the form of side frame registers 11 which may be in the form of pins and slots which simply act to steady and hold the centre and side sections engaged in the position shown in Figure 3. It should be noted that when the bed is used as a turning bed the interengaging features 11 disengage as shown in Figure 4.
The side sections 7 are carried by pairs of links 8 and 9 which join the pivot brackets 4 and 5 to the side sections 7 at points underneath the side sections and roughly midway across the side sections (see Figures 1 and 3).
These side sections are also connected by side frame pivot arms 13 to an end pivot frame 12, at each end of the bed, the pivot frame 12 being rigidly connected to the centre bed section 6. The movement of the bottom links 8 is restricted, in a downward direction, by bottom link stops 1Ø
In Figures 11 and 12 the turning movement of the bed i.e. the movement which enables the patient to be turned when on the bed, can be seen more explicitly.
In Figure.11 ~s shown an electric turning drive motor 16 which drives a -turning actuator screw 25 engaged with a turning trunion nut 26 pivoted on the pivot bracket 4.
Operation of the motor in one direction will cause thé centre section 6 to turn about its pivot producing lateral tilting action of the centre section and this ~2~78~5 will cause the side section 7 to move from the position shown in the Figure 11 to that shown in Figure 12. It will be seen that the interengaging features have been separated and the side section is now tilted at an angle opposite to that at which the centre section is retained in this position by the links 8 and 9 and by the links 12 and 13.
Operations of the motor 16 in the opposite direction will cause tilting of the frame 6 in the opposite direction and will cause the other side section to separate from the centre section thus producing a turning effect on the patient in the opposite direction.
Reverting to Figures 4 and 5, if a pure tilting movement of the mattress platform as a whole is required then each link 8 may be removed and each link 9 may be connected as shown in Figure 5 by means of a pin to a bracket 9A. This rigidifies the connection between the side sections 7 and the centre section 6 so that when the motor 16 is operated the matress platform comprising centre section 6 and two side sections 7 will tilt naturally as a whole.
The raising and lowering of the mattress platform and longitudinal tilting of the mattress platform is effected by the lifting arms 2 as shown in enlarged detail in Figures 6 and 7. Each link 2 is rigidly connected to an arm 2A pivoted at 2B. Each link 2 is moved by an electric motor 14 driving a lifting drive actuator screw 17. The action is assisted by a pair of gas struts 18 which relieve the stress in the motors and screws.
If both motors are operated simultaneously to turn the lifting arms in opposite directions the matress platform will be bodily raised or lowered.
If the motors 14 are operated so as to turn the arms 2 in the same direction the mattress platform will longitudinally tilt in one direction or the other.
Alternatively if one of the motors 14 is operated so as to turn one of the arms 2 whilst the other arm 2 remains stationery, the mattress platform will longitudinally tilt in one direction or the other.
As shown in Figures 8, 9 and 10 there is provision for raising a backrest. The backrest consists of the end portions 7A of the two side sections and the end portions 6A of the centre section of the mattress platform, all of these end portions being pivoted on pivot line 30. The centre section 6A can be raised to the position shown in Figure 9 by means of a backrest drive motor 15 supported in a drive bracket 22 attached to the underside of the mattress platform. The drive motor 15, through a backrest actuator screw ~9 and trunion nut 21, operates a pair of lifting links 20 which lift the centre section 6A to the position shown in Figure 9 or any intermediate position.
As the centre section lifts it carries with it the two side sections. This is achieved by a pair of plates 23 and 24 which are arranged as shown in Figure 10 so that the lower plate 23 on the centre sections 6A
engages beneath the upper plate 24 on the section 7A.
This method of ensuring that the three sections are raised and lowered together does not interfere with the turning action of the bed when the side sections and centre sections of the bed separate.
Turning now to Figures 13 and 14, a hinge flap 27 is provided in the centre of the centre section 6 of the mattress platform. At each side of the flap 27 are pairs of quick release hinge/loca-ting pins. If the pins 28 on one side of the flap are released the other pins 28 on the other side of the flap act as a hinge and the flap can be lowered. With this facility the flap can be lowered from either side of the bed. A flap of this kind is used for toilet purposes etc. The movement of the flap is limited by a stop cable 29 as shown in Figure 14.

One of the pair of lifting arms is pivoted in turn to an interlink 3 pivoted to a pivot bracket 4. The other lifting arm 2 is pivoted directly to a pivot 5.
The pivot brackets 4 and 5 (best seen in Figures 3 and 4) act as the pivot supports for the centre section 6 of amattress platform which is (as seen best in Figure 1) also comprises two side sections 7. The side sections 7 are not hinged directly to the centre section but simply have interengaging features in the form of side frame registers 11 which may be in the form of pins and slots which simply act to steady and hold the centre and side sections engaged in the position shown in Figure 3.

The side sections 7 are carried by pairs of links 8 and 9 which join the pivot brackets 4 and 5 to the side sections 7 at points underneath the side sections and roughly midway across the side sections (see Figures 1 and 3).
These side sections are also connected by side frame pivot arms 13 to an end pivot frame 12, at each end of the bed, the pivot frame 12 being rigidly connected to the centre bed section 6. The movement of the bottom links 8 is restricted, in a downward direction, by bottom link stops 1Ø
In Figures 11 and 12 the turning movement of the bed i.e. the movement which enables the patient to be turned when on the bed, can be seen more explicitly.
In Figure.11 ~s shown an electric turning drive motor 16 which drives a -turning actuator screw 25 engaged with a turning trunion nut 26 pivoted on the pivot bracket 4.
Operation of the motor in one direction will cause thé centre section 6 to turn about its pivot producing lateral tilting action of the centre section and this ~2~78~5 will cause the side section 7 to move from the position shown in the Figure 11 to that shown in Figure 12.

The backrest consists of the end portions 7A of the two side sections and the end portions 6A of the centre section of the mattress platform, all of these end portions being pivoted on pivot line 30. The centre section 6A can be raised to the position shown in Figure 9 by means of a backrest drive motor 15 supported in a drive bracket 22 attached to the underside of the mattress platform.
