The attachment 101 is provided with two upper and lower hooks 101a for bolts 102 screwed to the inner surface of the headboard RH or the like. The hook 101a of the bolt 102 is formed in a hook shape protruding downward. In this connection tool, the component plate S is laterally moved so that the upper and lower two bolts 102 provided on the head board RH or the like are received below the hook portion 101a. Then, by moving the component plate material S downward so as to drop it, the bolt 10
2 is inserted into the inside of the hook portion 101a, hooked, the component plate S is combined with the headboard RH, and the bolt 102 is further tightened to make a final fastening with the component plate. Headboard RH
And so on. According to the connecting tool shown in FIG. 13, such a connecting operation is typically performed such that the bolts 102 are introduced inside the hook-shaped hooking portions 101 a as described above. It is easy to perform because it can be done by moving it to the side and then dropping it, and the bolts can also be used to release the connection between the component plate S and the headboard RH, etc., which is required when moving the bed. After the component 102 was loosened, the component plate S was lifted upward so as to allow the bolt 102 to come out of the hook portion 101a, and then moved to the side, thereby being easily achieved.

[0004]

However, FIG.
In the connecting tool shown in FIG. 3, two upper and lower bolts 102, 102 screwed to the side of the head board RH or the like.
If there is an error in the interval between the bolts 1
In some cases, it may not be possible to allow the shaft portion 02 to properly enter the inside of the hook portion 101a positioned below the attachment portion 101 of the coupling tool. In addition, structurally, the connector of the component plate S located on the left side of the bed and the connector of the component plate S located on the right side have to be configured and prepared as symmetrical shapes.

However, the metal fittings disclosed in the publication are provided with notches continuously engaging with the head above and below the large-diameter hole into which the head of the mounting screw provided on the side of the headboard or the like enters. Both the coupling operation and the disconnection operation require moving the side of the component plate in the longitudinal direction of the component plate, and the disconnection operation requires otherwise completely removing the mounting screw, It is difficult to easily perform such a connection operation. Further, when an error occurs in the interval between the two mounting screws provided vertically on the side of the headboard or the like, it is difficult to provide a margin corresponding to the error. That is, in the case of the metal fittings disclosed in the publication, the large-diameter hole is enlarged in order to absorb such an error. However, if the large-diameter hole is simply enlarged, the lower mounting screw is removed. It cannot be sufficiently ensured that the shaft of the lower mounting screw is properly inserted into the notch that is continuous with the large-diameter hole to be inserted.

Accordingly, the present invention solves the disadvantages of the prior art, and more particularly, it relates to a plate member at the bottom of the bed provided on both the left and right sides of the bed along the length direction of the bed and the width direction of the bed.
