[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 facing an unprecedented aging society, and the number of elderly people who are hospitalized for a long time is increasing. Many elderly people suffer from dementia, which is a great burden for nursing care. Therefore, in hospitals, in order to reduce the burden on caregivers and the like, measures have been taken in terms of equipment and facilities.

[0003]

For example, a patient with dementia may get out of bed at night and wander around. That is, in a bed having a usual plug-in side fence, the side fence can be easily removed, and moreover, the entire side surface of the bed is not covered, and it is impossible to prevent the patient from getting out of the bed. The present invention has been proposed from such a background, and even if a patient with dementia gets out of bed and tries to wander, the side fence is configured so as not to easily get out of bed, and the side fence is locked. An object of the present invention is to provide a lock mechanism for a side fence such as a bed that prevents the mechanism from being easily operated by a patient.

[0004]

In order to solve the above-mentioned problems, the present invention relates to a bed or the like provided with an insertable side fence, which is inserted into an accessory mounting hole on a side frame. Has a base part that holds an insertion pipe for holding and a fence part that is attached to the base part.While forming a stopper hole at the place where the insertion side fence of the side frame is to be attached, the stopper hole is elastic. The lock operation lever is provided on the base so as to be rotatable, and the lock operation lever is provided with a stopper piece to be locked. In the above configuration, the fence portion of the pluggable side fence is a peripheral pipe,
It is characterized in that it is constituted by a board of a flexible member.

[0005]

[Operation] When the pluggable side fence is attached to the accessory mounting hole on the side frame through the plug pipe, the stopper piece of the lock operation lever at the base of the pluggable side fence is inserted into the stopper hole on the side frame. The lock operation lever is locked by being spontaneously locked, and the insertable side fence is fixedly supported in the accessory mounting hole without coming off. To release the locked state of the lock operating lever, the lock operating lever is operated against elastically locking the stopper piece in the stopper hole on the side frame. The strip can be removed from the stopper hole and the bayonet side fence removed. Therefore, since it is difficult for a demented person to remove the plug-in side fence, the demented person cannot easily get out of the bed and is locked in the bed.
The wandering of demented persons is prevented in advance.
