Abstract

PROBLEM TO BE SOLVED: To enable holding of the locked state of a board by a gravity alone by arranging a retaining part to be caught in a retaining hole of a bed frame at a lower part of a hook to set the center of gravity at a position where the retaining part is caught in the retaining hole by the gravity. SOLUTION: A pair of right and left mounting holes 3 are bored in a front frame material 5 of a bed frame S vertically piercing it and a retaining hole 4 is provided near one mounting hole 3. A pair of support posts 1 to be inserted through the mounting holes 3 is mounted on the right and left of a lower part on the side of the internal surface of a board B and a hook 2 is arranged near the one support post 1 to be mated with the retaining hole 4. When lower parts of the support posts 1 are mounted into the mounting holes 3, a lower end rim 22 of the hook 2 contacts a rim 41 of the retaining hole 4. But the lower end rim 22 is formed into an arc and hence, turns in the direction of a retaining part 20 separates with respect to the support posts 1. When the lower ends of mounting pieces 10 integrated with the support posts 1 hit the top surface of the bed frame S, the retaining part 20 is returned to the original position by the gravity of the hook 2 to be positioned and held in the bed frame S.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a headboard and footboard mounting structure for a medical bed.

[0002]

2. Description of the Related Art A conventional medical bed installed in a hospital or the like has a headboard attached to the user's head and a footboard attached to the side of the user in an upright position, similarly to a bed installed in a general home. , The appearance quality of the bed is improved.

In the case of a medical bed, for example, when the condition of the observer deteriorates, it is necessary to quickly remove the headboard and footboard and move the bed in which the observer is supine to an operating room or the like. .

[0004]

However, the conventional bed has a drawback that the headboard and the like cannot be easily and quickly removed from the bed frame because the headboard and the footboard are locked to the bed frame.

Accordingly, an object of the present invention is to make it possible to easily and quickly remove a headboard or the like from a bed frame in an emergency.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a pair of right and left mounting holes vertically penetrating right and left of an end portion and a locking hole formed near one of the mounting holes. And a stand-up board having a pair of left and right support columns inserted into the mounting holes and hooks locked in the locking holes and pivotally pivoted on the upper portion. The hook has an operation portion at an upper portion, and has a hook-shaped locking portion which is hooked on a hole edge of the locking hole at a lower portion, and at a position where the locking portion is hooked on an edge of the locking hole by gravity. The center of gravity is set.

A hook for locking a board such as a head board to a bed frame is locked by a locking hole formed in the bed frame by its gravity, so that only the operation portion is pushed against the gravity to be operated. The hook escapes from the locking hole and is unlocked.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, an embodiment of the present invention will be described.
This will be described with reference to the drawings. In the figure, (S) shows a bed frame, (B) shows a board (headboard), respectively, and the bed frame (S) has a hollow metal front frame member (5) and a side frame member (6) ( 6) and the like are combined in a frame shape, a bottom (not shown) is mounted on the head frame (S), and a mattress is laid on the bottom to form a bed.

As shown in FIG. 3, a pair of left and right mounting holes (3) (3 ') are vertically penetrated in the front frame member (5) of the bed frame (S) at intervals. The hole is opened. In the vicinity of the one mounting hole (3), a locking hole (4) formed of an elongated slit is provided.

On the other hand, a pair of left and right support columns (1) and (1 ') to be inserted into the mounting holes (3) and (3'), and one of the support columns ( A hook (2) which is disposed near 1) and engages with the locking hole (4) is attached.

As shown in FIG. 1, the upper part of the support column (1)
The U-shaped attachment piece (10) fixed to the inner surface of the board (B) by welding or the like is vertically welded to the distal end opening of the U-shaped attachment piece (10), and the lower part can be inserted into the attachment hole (3). Have been.

As shown in FIGS. 1 and 2, the hook (2) includes an L-shaped bracket (25) fastened to the mounting piece (10) by bolts (27) (27), and the bracket (25). (25) is interposed between a fixed piece (26) fixed to the base side of the bracket (25) with a gap from the tip of the bracket (25), and the upper part is pivotally mounted on a pin (24) so as to be swingable. I have.

The hook (2) is connected to a bracket (25).
An operating portion (23) projecting outside from a gap between the locking piece (26) and the fixing piece (26) is integrally provided at an upper portion, and a hook-shaped locking portion hooked on a hole edge (41) of the locking hole at a lower portion. (20) is provided.

The hook-shaped engaging portion (20) has a lower edge (22) formed in an arc shape and an upper edge (21) connected to the lower edge (22) formed in a horizontal shape. As shown in FIG. 2, the upper end edge (21) is swingably pivoted by the pin (24) so as to be located on the inner wall surface of the bed frame (S).

That is, when the hook (2) is pivotably pivoted by the pin (24), the hook (2) is inserted into the locking hole (4) by the gravity of the hook (2). The center of gravity is set so that the upper edge (21) in 20) corresponds to the inner wall surface of the bed frame (S).

Therefore, when the board (B) is mounted on the bed frame (S), when the lower portion of the support column (1) is inserted into the mounting hole (3) of the bed frame (S), the hook (2) is locked. The lower edge (22) of the portion (20) abuts the hole edge (41) of the locking hole (4).
Since the lower edge (22) of the support pillar (2) is formed in an arc shape, the hook (2) descends together with the support pillar (1) while supporting the support pillar (1).
, The locking portion (20) rotates in a direction in which it separates.

The mounting piece (1) integrated with the support column (1)
When the support pillar (1) is inserted through the upper and lower mounting holes (3) and (3), the lower end of the hook (2) is engaged with the hook (2) as shown in FIG. Part (2
0) returns to the original state due to the gravity of the hook (2), and the lower edge (22) and the upper edge (21) of the locking portion (20) are located in the bed frame (S). Therefore, hook (2)
The board (B) is locked to the bed frame (S) because the upper edge (21) of the board is located inside the bed frame (S), thereby preventing the board (B) from being removed from the bed frame (S). Can be.

When the operating portion (23) of the hook (2) is pressed against the hook (2) against the gravitational force of the hook (2) in the locked state of the board (B) shown in FIG. Since the hook (2) rotates about the pin (24) as the center of rotation, the locking portion (20) rotates to the left in FIG. 2, and the upper edge (21) is inserted into the locking hole (4). It will be the corresponding position.

Then, when the board (B) is lifted upward, the hook (2) is moved from the locking hole (4) of the bed frame (S) to the left and right support columns (1) and (1 ') through the mounting hole (3). ) (3 '), and the board (B) is removed from the bed frame (S).

The board (B) shown is a head board, but the foot board has a similar mounting structure.

[0021]

According to the present invention, the locked state (attached state) of the board to the head frame only by the gravity of the hooks.
By rotating the hook against the gravity of the hook, the locked state by the hook can be released and the board can be removed from the bed frame.

Accordingly, there is no need to use a lock spring or the like for holding the hook in a locked state.
It can provide a simple structure that is hard to break down, and can easily and quickly remove the board from the bed frame in an emergency.
