Description

[Detailed Description of the Invention] This invention relates to a bed device in which casters are attached to the four corners of the bed body.

In general, a bed device comprises a rectangular bed body by connecting a board body to both ends of a pair of side plates spaced apart from each other in parallel, and a mattress mounted on the bed body and placed on a floor plate. Further, casters are attached to the four corners of the bed body so that the bed body can be easily moved.

Conventionally, in the bed device having the above structure, casters have been attached and fixed to the four corners of the bed body after the bed body is assembled. That is, after the side plates and the board body are connected by a connector, the casters are attached to the side plate or the board body at the corner of the bed body. Therefore, the work of connecting the side plate and the board body and the work of attaching the casters must be performed separately, resulting in poor workability. Further, since screws are required to attach the caster to the corner of the bed body, the cost also increases.

This idea was made based on the above circumstances, and its purpose was to be able to simultaneously perform the work of connecting the side plate and the board body and the work of installing the casters, and to avoid the need for special screws to install the casters. The objective is to provide a bed device that does not

An embodiment of this invention will be described below with reference to the drawings. The bed device shown in Fig. 1 is a bed main body 1.
It is equipped with The bed main body 1 is formed into a rectangular shape and includes a pair of side plates 2 that are spaced apart from each other in parallel and face each other, and a head board 4 and a foot board 5 as board bodies connected to both ends of the side plates 2 by connectors 3, respectively. There is. A floor plate (not shown) is installed on the bed body 1, and a mattress 6a is placed on this floor plate.

As shown in Figures 3 and 4, the connector 3 is made by bending a plate into an L-shape, with a large number of through holes 6 bored on one side and holes opening downward on the other side. Two engagement grooves 7 are formed in the vertical direction. One side of the connector 3 is fixedly attached to the inner surface of the end of the side plate 2 by a screw 8 passed through a through hole 6. Also,
On the other side of the connector 3 are each board 4, 5 and caster 9.
is installed and fixed. In other words, two through holes 10 are formed in the lower part of both widthwise ends of each of the board bodies 4 and 5 in the vertical direction. Also, caster 9
is a support portion 12 that rotatably holds the roller 11;
and a mounting part 13 to which this support part 12 is attached, and this mounting part 13 has the above-mentioned boards 4,
Two through holes 14 are bored corresponding to the five through holes 10. A screw 15 is passed through the through hole 10 of each board 4, 5 from the outside, and the end of the screw 15 protruding toward the inside is engaged with the engagement groove 7 formed on the other side of the connector 3. At the same time, the nut 16 is passed through a through hole 14 formed in the mounting portion 13 of the caster 9, and a nut 16 is screwed to the end protruding from the through hole 14.

According to the bed device configured in this way, when one side of the connector 3 is connected to the side plate 2 and the other side is connected to each board 4, 5, the caster 9 can be attached and fixed at the same time. That is, the work of connecting the side plate 2 and the boards 4, 5 using the connector 3 and the work of attaching the caster 9 can be performed simultaneously.
Moreover, since the caster 9 can be attached using the screws 15 that connect the connector 3 and each board 4, 5, no special screws are required for attaching the caster 9.

In the embodiment described above, two engaging grooves are formed in the vertical direction on the other side of the connector, and the screws are engaged therein, but the engaging grooves may be replaced by through holes. Further, although the caster is attached to the side of the connector on the side where the board is attached, it may be attached to the side on the side where the side plate is attached.

As mentioned above, this idea is to fix one side of the L-shaped connector to the side plate with screws, form an engagement groove on the other side, and use this engagement groove to attach the mounting part of the caster to the board body. It was made to engage with the screw of. Therefore, the work of connecting the side plates and the board body using the connectors and the work of attaching the casters to the four corners of the bed body can be performed at the same time, so that the efficiency and ease of the assembly work can be improved. Also,
Since the casters can be attached using the screws that connect the connector and the board body or the side plates, there is no need for special screws to attach the casters, which has advantages such as being economical.
