DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lock mechanism for a side fence such as a bed suitable for a patient suffering from dementia.

[0002]

2. Description of the Related Art At present, Japan is entering an unprecedented aging society, and the number of elderly patients hospitalized for a long time is increasing. Many elderly people suffer from dementia, which is a great burden for nursing care. Therefore, in hospitals, countermeasures have been taken in terms of facilities and equipment in order to reduce the burden on caregivers and the like.

[0003]

For example, a patient with dementia may get out of bed at night and wander. That is, in a bed provided with a normal plug-in side fence, the side fence can be easily removed, and not all the side surfaces of the bed are covered, and the patient cannot escape from the bed. The present invention has been proposed in view of such a background, and a side fence is configured so that even if a patient with dementia tries to get off the bed and wander, the side fence is not easily got off, and the side fence is locked. It is an object of the present invention to provide a lock mechanism for a side fence such as a bed, wherein the mechanism cannot be easily operated by a patient.

[0004]

According to the present invention, there is provided a bed or the like having a plug-in side fence, wherein the plug-in side fence is inserted into an accessory mounting hole on a side frame. And a fence mounted on the base for forming a stopper hole in the side frame where a plug-in side fence is to be mounted. A lock operation lever, which is provided with a stopper piece for temporarily locking, is rotatably provided on the base. In the above-described configuration, the fence portion of the plug-in side fence includes a peripheral pipe,
And a board made of a soft member.

[0005]

[Action] When a plug-in side fence is attached to the accessory mounting hole on the side frame via a plug-in pipe, the stopper piece of the lock operation lever at the base of the plug-in side fence is inserted into the hole for stopper on the side frame. The locking operation lever is locked by the spontaneous locking, and the plug-in side fence is fixed and supported in the accessory mounting hole without being pulled out. To release the lock state of the lock operation lever, the lock operation lever is operated by operating the lock operation lever against the stopper piece resiliently engaging the stopper hole on the side frame. The piece can be disengaged from the stopper hole and the plug-in side fence can be removed. Therefore, since the operation of removing the plug-in side fence is difficult for a demented person, the demented person cannot easily get out of the bed and is kept in the bed,
The wandering of the demented person is prevented beforehand.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a lock mechanism for a side fence of a bed or the like according to the present invention will be described below with reference to the accompanying drawings by taking an embodiment. In the bed 1 shown in FIG. 1, the bed 1 is provided with a full-type plug-in side fence 2, and the plug-in side fence 2 is provided with both side frames 3.
A configuration in which a pair of each is connected to each other to cover substantially the entire side surface of the bed, and the plug-in side fence 2, the headboard 4 having the same height, and the footboard 5 are provided at both ends of the bed 1 on the longitudinal side. And

As shown in FIG. 2, the insertable side fence 2 has a base 8 holding a pair of insertion pipes 7a and 7b for inserting into accessory attachment holes 6 on the side frame 3, and is attached to the base 8. And the fence 9 formed. In the base portion 8, a lock operation lever 11, which is always urged to rotate, is provided at a central position between the insertion pipes 7 a, 7 b so as to be engaged with a stopper hole 10 provided in the side frame 3. This lock operation lever 1
1 is rotatably mounted by a bolt 14 via a coil-shaped spring member 13 between both side portions of a rectangular notch concave portion 12 formed at a lower central portion of the base 8 as shown in FIG. ing. The lock operation lever 11 has a stopper piece 15 projecting from a lower end thereof, and is locked in a stopper hole 10 in the side frame 3 by a resilient force of a spring member 13. Further, a gap G is formed between the upper part of the notch recess 12 in the base 8 and the lock operation lever 11 so that a finger of an operator who performs the retraction operation of the lock operation lever 11 can be inserted. (See FIG. 4).

In the plug-in side fence 2 as described above,
As shown in FIG. 2, the fence portion 9 is configured by a square loop-shaped peripheral pipe 16 and a board 17 made of a soft member, and the board 17 is formed on the peripheral pipe 16 by an inner side formed by the peripheral pipe 16. Is mounted so as to cover the central portion of the space portion, and a gap 18 is provided near both ends on the longitudinal side of the peripheral pipe 16.
Is formed. Further, the board 17 may be formed of a soft cushion member on the side facing the floor 19 of the bed 1.

Further, in the bed 1 as described above,
The head board 4 and the foot board 5 are constituted by peripheral pipes 4a, 5a and boards 4b, 5b of soft members, respectively. Also, the peripheral pipes 4a, 5a and the board 4 on the top side of the head board 4 and the foot board 5
b, 5b, there is a gap 20, and the headboard 4
In addition, a grip 21 covered with a cushion member is provided at both ends on the top side of the footboard 5 so as to make it easier to grasp. The height of the headboard 4 and the footboard 5 and the height of the plug-in side fence 2 are set higher than the height of a normal bed so that the patient does not straddle.

The lock mechanism of the side fence of a bed or the like according to the present invention is configured as described above. Next, the operation thereof will be described. Insert the side fence 2 into the accessory mounting hole 6 on the side frame 3 and insert the pipe 7
a, 7b, the stopper piece 15 of the lock operation lever 11 of the base 8 of the plug-in side fence 2
The spring member 13 is pressed into the stopper hole 10 provided between the accessory attachment holes 6 on the side frame 3 against the urging force of the spring member 13, and the stopper piece 15 is pressed by the spring member 13.
Is locked in the stopper hole 10 (see FIG. 4), the lock operation lever 11 is in a locked state, and the plug-in side fence 2 can be fixedly supported without falling off.

On the other hand, the plug-in side fence 2 is unnecessary for nursing care and medical treatment, so it is removed. That is, the nurse inserts a finger from the gap G between the upper part of the notch recess 12 in the base 8 and the lock operation lever 11, and pulls the lock operation lever 11 toward the front side against the urging force of the spring member 13. Operate as follows. Then, the lock operation lever 1
1 The stopper piece 15 protruding from the lower end is
Since it is separated from 0, the restriction of the plug-in side fence 2 is released, and the plug-in side fence 2 can be easily pulled out from the accessory mounting hole 6. Lock operation lever 1 as described above
1 is arranged in the center of the lower portion of the base 8 of the plug-in side fence 2, so that it is difficult for a patient on the floor 19 of the bed 1 to reach. In addition, the operation of removing the plug-in side fence 2 as described above can be performed. Since it is difficult for a demented person, the demented person cannot easily get out of the bed 1 and stays in the bed 1 to prevent the demented person from wandering.

Since the plug-in side fence 2, the headboard 4 and the footboard 5 are higher than the normal height, that is, the height is set so that the patient cannot step up their feet. So easily the demented person cannot get out of bed 1 and wandering is prevented beforehand.

[0013]

As described above, according to the present invention, a demented person can be kept in a bed by applying a tall insertion side fence, a headboard and a footboard to the bed. In addition, wandering can be prevented beforehand even if the eyes of the monitoring are not perfect. Further, since the operation of the lock mechanism is difficult for a demented person, the plug-in side fence is not easily pulled out by mischief, and the demented person can be further kept in the bed.
