Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a stopper mechanism in a lumbar movable care bed.

(Prior Art and Problems) For example, for a sick person who has been bedridden for a long time, such as a bedridden elderly person, a caregiver may put on and take off a nightgown, change a diaper, or turn someone over to relieve pressure sores. They have to perform various nursing care tasks, such as removing moisture from futons. In such nursing care work, turning the sick person over in bed is extremely hard work, difficult for one caregiver to do alone, and it is also painful for the sick person. Such turning over can be easily performed by moving the patient's hips in the opposite direction to the direction in which the patient is turning over. Therefore, in recent years, a nursing care bed with a movable lumbar region has been proposed in which the lumbar floor plate is supported on a floor plate support frame so as to be movable in the width direction of the bed frame.

However, such conventional nursing care beds do not have an appropriate stopper mechanism for making the lumbar floor plate movable as necessary and fixing it at a predetermined position.

The present invention has been made in view of these points, and an object of the present invention is to provide a suitable stopper mechanism that is easy to operate.

(Means for Solving the Problems) The structure of the present invention for solving the above problems will be explained with reference to drawings corresponding to embodiments.The stopper mechanism in the lumbar movable care bed of the present invention is as follows. In the lumbar movable care bed in which the lumbar floor plate 1b is supported on the floor plate support frame 3 so as to be movable in the width direction of the bed frame 2, a stopper guide 4 is provided in the width direction of the floor plate support frame 3, Stopper holes 5a, 5b, 5c, . A stopper pin 7 supported so as to protrude in the direction of the stopper guide 4 is provided, and an actuation piece 9 is provided protruding from an actuation rod 8 rotatably supported under the waist floor plate 1b. The stopper pin 7 is made to retreat from the stopper guide 4 against the bias of the spring 6, and the operating levers 10a and 10b for rotating the operating rod 8 are provided on the operating rod 8 by interlocking arms. 11a, 11b and interlocking links 12a, 12b, the waist floor plate 1
It is provided on the lower side of both ends of b.

(Operation) Next, the operation of the present invention will be explained with reference to the drawings corresponding to the embodiments.

In the above configuration, the operating levers 10a, 10
When the operation b. is not performed, the stopper pin 7 protrudes in the direction of the stopper guide 4 due to the bias of the spring 6, and therefore corresponds to one of the stopper holes 5a, 5b, and 5c of the stopper guide 4. If so, the stopper pin 7 is fitted into one of these as shown in FIGS. 2 and 5, and the waist floor plate 1b cannot be moved in the width direction of the floor plate support frame 3. There is.

At this time, when the operating lever 10a is rotated to pull the interlocking link 12a to the right in FIG. 5 and the operating rod 8 is rotated clockwise via the interlocking arm 11a, the operating piece 9 is also rotated in the same direction. Move and stopper pin 7
are moved backward against the bias of the spring 6 and removed from the stopper holes 5a, 5b, 5c, . . . , so that the waist floor plate 1b becomes movable. In this state, when you release your hand from the operating lever 10a and move the lumbar floor plate 1b, the stopper pin 7 automatically closes the stopper holes 5a, 5b, 5c, . . . under the bias of the spring 6 at a predetermined movement position. ...and becomes fixed. To release the stopper, rotate the other operating lever 10b and pull the interlocking link 12b to the left as shown in FIG.
This can also be done by rotating the actuating rod 8 clockwise via 1b in the same manner as described above. In this way, the stopper can be released by operating either of the operating levers 10a, 10b provided on the lower side of both ends of the lumbar floorboard 1b, so the caregiver can adjust the bed depending on the direction in which the patient is to be turned over. The stopper can be released from either side.

(Example) Next, embodiments of the present invention will be described with reference to the drawings.

In FIGS. 1 and 2, reference numerals 1a and 1c indicate a back floor plate and a foot floor plate, respectively, which are adjacent to the lumbar floor plate 1, and these floor plates 1a, 1b, and 1c and the floor plate support frame 3 are moved by an appropriate elevating mechanism. It can be a mechanism for raising and lowering and raising and lowering. The floor plate support frame 3 is provided with a pair of guide rails 13a, 13b in the width direction of the bed frame 2, with opening sides facing each other. , 13b, vertical support rollers 14a, 1, respectively.
4b are provided, and these support rollers 14
By attaching the guide rails 13a and 14b to the guide rails 13a and 13b, the lumbar floor plate 1b is attached to the bed frame 2.
It is supported so that it can move freely in the width direction. Further, the stopper pin 7 is held in a holder 16 provided on the support frame 15 so as to be freely advanced and retracted.
A compression coil spring 6 is installed between the holder 16 and the distal end side flange 17, and the through hole 18 of the actuating piece 9 is fitted into the stopper pin 7 on the outside of the holder 16.

(Effects of the invention) As described above, the present invention provides a movable lumbar nursing care bed in which the release operation of the stopper that disables the movement of the lumbar floor plate can be performed by either one of the operating levers provided on the lower side of both ends of the lumbar floor plate. Since the stopper can be released by operating the stopper, the caregiver can release the stopper from either side of the bed depending on the direction in which the patient is being turned over.
