Pivoting device
A pivoting device for pivoting of segments ( 4 ) which are pivotable relative to one another of a bearing construction ( 2 ), providing a bearing surface ( 3 ) for a mattress, a cushioning element or the like, of an item of furniture for sitting and/or lying on, in particular a bed. In order to produce a pivoting device which requires a comparatively small installation space while also having safe operation, the invention proposes a pivoting device which includes an electromotive drive device ( 13 ) which is arranged on the end face between two neighboring segments ( 4 ).
1. A bed, such as for a hospital or nursing home, comprising:
a bearing construction configured to provide a bearing surface for a mattress, the bearing construction formed by segments that are pivotable relative to each other; and
a pivoting device arranged between, and connected to, a first segment and a second segment of the bearing construction to pivot the first segment relative to the second segment, the pivoting device includes:
a drive device including a motor and a transmission;
a shaft flanged to the transmission, the shaft including a first semi-shaft and a second semi-shaft that are both within a common housing; and
a supporting element that includes a first portion and a second portion, each of which are formed by the housing.
2. The bed of claim 1 , wherein the first and the second semi-shafts each include a fixing flange operable to connect the first segment to the pivoting device.
3. The bed of claim 1 , wherein the first portion and the second portion of the supporting element each include a neck flange operable to connect the second segment to the pivoting device.
4. The bed of claim 1 , wherein the first segment and the second segment each include hollow frame parts.
5. The bed of claim 2 , wherein the fixing flanges are web-shaped holders inserted in and fixed to hollow parts of a frame of the first segment to secure the first segment to the pivoting device.
6. The bed of claim 3 , wherein the neck flanges are web-shaped holders inserted in and fixed to hollow parts of a frame of the second segment to secure the second segment to the pivoting device.
7. The bed of claim 1 , wherein at least one of the first segment and the second segment are moveable on the pivoting device in a direction transverse to a longitudinal axis of the first semi-shaft and the second semi-shaft.
8. The bed of claim 1 , wherein the drive device includes a drive housing that accommodates the motor and the transmission.
9. A bed, such as for a hospital or nursing home, comprising:
a first segment including:
a first mattress bearing surface; and
a first frame defining a first hollow receptacle;
a second segment including:
a second mattress bearing surface; and
a second frame defining a second hollow receptacle;
a pivoting device arranged between the first segment and the second segment, the pivoting device including:
a drive device including a motor and a gear transmission;
a shaft rotatable by the motor and transmission the shaft including a first semi-shaft and a second semi-shaft;
a first fixing flange extending from the shaft and secured within the first hollow receptacle to secure the first segment to the pivoting device; and
a fixed bearer element housing both the first semi-shaft and the second semi-shaft, the fixed bearer element including a first neck flange extending therefrom, the first neck flange secured within the second hollow receptacle to secure the second segment to the pivoting device;
wherein activation of the drive device pivots the first segment relative to the second segment.
10. The bed of claim 9 , wherein the first frame surrounds the first mattress bearing surface and the second frame surrounds the second mattress bearing surface.
11. The bed of claim 9 , wherein the drive device is mounted to the fixed bearer element.
12. The bed of claim 9 , wherein the first fixing flange extends from an end of the first semi-shaft, and a second fixing flange extends from an end of the second semi-shaft.
13. The bed of claim 9 , wherein the first neck flange extends from a first end of the fixed bearer element and a second neck flange extends from a second end of the fixed bearer element.
14. The bed of claim 9 , wherein the first neck flange is fixed.
15. The bed of claim 9 , wherein the first segment is slidably movable along the first fixing flange.
16. A bed, such as for a hospital or nursing home, comprising:
a pivoting device including:
a drive device including a motor and a transmission;
a fixed bearing element;
a first neck flange and a second neck flange at opposite ends of the fixed bearing element;
a first semi-shaft and a second semi-shaft both housed within the fixed bearing element and extending from opposite sides of the drive device; and
a first fixing flange at an end of the first semi-shaft and a second fixing flange at an end of the second semi-shaft;
a first segment including a mattress bearing surface and a pair of hollow receptacles, one hollow receptacle is in cooperation with the first fixing flange and the other hollow receptacle is in cooperation with the second fixing flange; and
a second segment including a mattress bearing surface and a pair of hollow receptacles, one hollow receptacle is in cooperation with the first neck flange and the other hollow receptacle is in cooperation with the second neck flange;
wherein activation of the motor rotates the first and the second semi-shafts, and the first and the second fixing flanges, to pivot the first segment relative to the second segment; and
wherein the first neck flange and the second neck flange remain stationary during activation of the motor and rotation of the first and the second semi-shafts.
17. The bed of claim 16 , wherein the fixed bearing element includes a housing, the first and the second semi-shafts are rotatably mounted within the housing.
18. The bed of claim 17 , wherein the first neck flange and the second neck flange are both integral with the housing.
19. The bed of claim 17 , wherein the drive device is mounted to the housing.
20. The bed of claim 16 , wherein the first segment is slidably movable along the first and the second fixing flanges.
