Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a board locking mechanism for a bed, in which a head side or leg side board of the bed can be detached and prevented from being accidentally detached.

[0002]

2. Description of the Related Art Conventionally, many beds have an integral structure in which a steel material, a steel plate or the like is processed into a pipe frame shape and the surface is coated, and it has been difficult to carry it into a patient's room. Recently, the demand for beds for home use has increased due to an increase in the aging population, and a structure having a structure that can be easily carried into a house or a room is desired. So, to make it easier to carry the bed, for example,
The plywood and the synthetic resin boards provided on the bed head side and the leg side, which are configured to be attachable / detachable by a pin member and a hook-shaped mounting metal fitting, are commercialized on the end face on the longitudinal side of the main frame.

[0003]

However, with the above-mentioned structure, when the board is inadvertently taken, the board is simply locked by the hook-shaped mounting metal fittings, so that the board is easily disengaged. It will be a little loose,
For example, there are cases where it is not possible to use the board to place small items, medical equipment, etc. at ease. The present invention has been proposed from such a background, and provides a board locking mechanism in a bed that has a structure that is as simple as possible, that does not accidentally come off, and that can be held without rattling. The purpose is to

[0004]

In order to solve the above-mentioned problems, the present invention provides a head-side or leg-side board of a bed for attaching the board to a longitudinal side end portion of a main frame of the bed. While the board receiver is provided in a protruding manner, an engaging metal fitting for engaging with the board receiver is provided on the board side, and the board receiver is projected from the longitudinal end surface of the main frame and a pair of pin members are projected. The locking fitting has a pair of hook-shaped members adapted to be locked to the pin member of the board receiver,
The present invention is characterized in that a rotatable stop lever for restraining the pin member in a state of being locked to the hook-shaped member and for releasing the pin member in a detachable manner is provided. In the above-mentioned configuration, the stop lever is rotatably provided on the locking metal fitting so as to open or block the opening surface for introducing the pin member in the hook-shaped member.

[0005]

[Operation] For the board receiver on the long side of the main frame,
When mounting the board, move the stop lever to open the open surface of the hook-shaped member in the board-side locking metal fitting, and engage the hook-shaped member with the pin member of the board receiver at the longitudinal end of the main frame. Then, the stop lever is displaced to close the opening surface of the hook-shaped member, and the attachment is completed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a board locking mechanism in a bed according to the present invention will be described below with reference to the accompanying drawings with reference to an embodiment. A bed 1 is shown in FIG.
Is configured to be detachably attached. That is, the board receiving member 4 for mounting the board 3 is projected from both ends of the main frame 2 of the bed 1 on the longitudinal side, and the board receiving member 4 is locked on the board 3 side. The metal fitting 5 is provided.

The board receiving member 4 is a main frame 2
The frame surface is projected in the longitudinal direction from both longitudinal end portions, and the pair of pin members 6 are vertically arranged in a protruding manner.

The locking fittings 5 are attached to the lower part of the board 3 in the vicinity of both ends on the width side, and the pair of hook-shaped members 7 and 8 are adapted to be locked to the pin members 6 of the board receiving member 4. And a rotatable stop lever 9 for restraining the pin member 6 in a state of being locked to the upper hook-shaped member 7 and for releasing the pin member 6 in a detachable manner. The hook-shaped members 7 and 8 of the locking metal fitting 5 have their tips directed downward when they are attached to the board 3, and the pin member 6 of the board receiver 4 is inserted from the bottom to the inner recesses of the hook-shaped members 7 and 8. An opening is formed so as to be inserted into and locked by the locking portion 10 formed in a shape.

The stop lever 9 is rotatably axially fixed to a portion of the locking fitting 5 corresponding to the root of the lower hook-shaped member 8, and the locking portion 1 of the upper hook-shaped member 7 is locked.
It extends so as to block the open passage leading to zero. The tip of the stop lever 9 is sharpened so that it can be easily rotated, and is curved so as to be directed to the outside of the tip of the hook-shaped member 7. Also, such stop lever 9
Is urged by a coil spring 11 formed so that both ends thereof are widened so as to take a position on the side that cuts off the side that opens the opening passage that leads to the locking portion 10 of the hook member 7 on the upper side. ing. That is, one end of the coil spring 11 is fitted and fixed in the mounting hole 12 of the locking fitting 5, and the other end of the coil spring 11 is attached to the stop lever 9 and the stop lever 9 respectively.
Is attached so as to press and urge the hook-shaped member 7 in the direction in which it is displaced inward and outward. Further, as shown in FIG. 2, the locking fitting 5 is provided with a guide hole 13 for restricting the rotation range of the stop lever 9, and a restriction pin 14 projecting from the stop lever 9 is fitted and locked. I am letting you.

The board locking mechanism in the bed according to the present invention is as described above. Next, the procedure for mounting the board 3 will be described. When the board 3 is attached to the board receivers 4 at both ends of the main frame 2 on the longitudinal side, the stop lever 9 is used as an assisting force by the coil spring 11.
The upper hook-shaped member 7 is moved so as to open the opening passage to the locking portion 10. Then, the tip of the stop lever 9 is brought into the inside of the opening passage reaching the locking portion 10 of the upper hook-shaped member 7, and in this state, the hook-shaped members 7 and 8 of the locking metal fitting 5 are lengthened to the main frame 2. It is locked to the pin members 6 of the board receivers 4 at both ends of the side (see FIGS. 3 and 4). Then, use the stop lever 9 as the coil spring 1
It is possible to displace the opening 3 of the upper hook-like member 7 by displacing it with the urging force of the auxiliary member 1 as an assist, so that the board 3 can be mounted so as not to fall off the pin member 6 of the board receiver 4 (FIG. 5, (See FIG. 6). Since the weight of the board 3 is applied to the engaging portions of the hooking members 7 and 8 of the locking metal fitting 5 and the pin member 6 of the board receiving member 4, the board 3 is There is no rattling.

[0011]

As described above, according to the present invention, the board mounting structure can be made simple and can be mounted by a simple operation so that the board does not come off accidentally and the board is placed on the bed. It can now be held so that it does not rattle the body.
