BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bed side frame structure capable of simplifying the manufacturing process and reducing the weight.

[0002]

2. Description of the Related Art Conventionally, a frame such as a bed has been formed by pressing a steel material. Then, as shown in FIG. 3, for example, a floor receiving bracket 2, a starting receiving bracket 3, headboard and footboard mounting brackets 4, 5, a link receiver 6, and a curtain plate that are separately formed on the longitudinal frame 1. The metal fitting 7, the side rail receiver 8, etc. are connected by welding to be assembled.

[0003]

Therefore, in such a manufacturing process, there are many welding points and the number of steps until completion is large. In addition, since steel is used, the weight becomes heavy, and the carry-in and mobility deteriorate, and it is particularly unsuitable for home beds. There are issues such as. The present invention has been made to solve such problems, and the frame is integrally formed by extrusion molding.
An object of the present invention is to provide a bed side frame structure capable of simplifying the manufacturing process and reducing the weight thereof.

[0004]

In order to solve the above-mentioned problems, the present invention is an integrally molded side frame such as a hollow bed, which has a curtain plate portion on one side in the longitudinal direction. , And a locking groove portion for locking a receiver that supports the component parts of the bed along the longitudinal direction on the other surface side in the longitudinal direction. The receiving member has a locking hook portion that can be fitted into the locking groove portion from the end of the side frame. Furthermore, the side frame described above is divided into a plurality of parts, and has a joint member for connecting these side frames.
It is also possible to have a locking projection that corresponds to the shape of the locking groove, and to fix it by fitting it into the locking projection of the joint member so that the end faces of both side frames that are to be connected face each other. Is.

[0005]

[Operation] An attachment hole for a side fence or the like is formed in the integrally formed side frame. Then, the receiving tool is inserted along the locking groove portion and fixed at a predetermined position to complete the process. Therefore, the welding process becomes unnecessary and the process can be shortened.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A bed side frame structure according to the present invention will be described below with reference to the accompanying drawings. FIG. 1 shows a side frame 10 of the bed. The side frame 10 is made of a light metal such as aluminum by an extrusion molding process,
It is a hollow body with multiple spaces inside, and has both the required strength and light weight. Such side frame 10
Is the curtain plate portion 1 on one side of the side frame 10 in the longitudinal direction.
1 and has a locking groove portion 12 on the other surface side in the longitudinal direction for locking the receiver that supports the components of the bed along the longitudinal direction.

A decorative sheet made of vinyl chloride having a pattern such as wood grain can be attached to the curtain plate portion 11 on one side in the longitudinal direction of the side frame 10. On the other hand, the locking groove portion 12 on the other surface side in the longitudinal direction of the side frame 10 is formed on both the upper surface and the lower surface along the longitudinal direction. The locking groove portion 12 includes the side frame 1
From the 0 end, the metal fittings 13 for various components of the bed,
14 and 15 are inserted into the locking groove portion 12 via the locking hook portions 13a, 14a, 15a having a U-shaped cross section corresponding to the locking groove portion 12, and along the locking groove portion 12 up to a predetermined position. It is a structure that is moved by shifting and fixed with screws or the like. It is also possible to screw the link receiver 16 that receives the link below the floor to the inner end surface of the side frame 10. Further, the curtain plate portion 1 of the side frame 10
A mounting hole 17 such as a side fence is formed in the upper end surface on the inner side of 1.

Next, the manufacturing process of the side frame 10 as described above will be described. The side frame 10 is formed by extrusion molding, and then mounting holes 17 for side fences and the like are formed. Then, the receiving metal fittings 13 to 15 of various components of the bed are inserted into the locking groove portion 12 via the locking hook portions 13a, 14a, and 15a, and moved along the locking groove portion 12 to a predetermined position. And fix it with screws. The link receiver 16 is screwed to the inner end surface of the side frame 10. Since the process is completed in this way, the conventional welding process is unnecessary and the process can be shortened. Further, since the side frame 10 is a hollow body made of a light metal such as aluminum, the side frame 10 can provide necessary strength and can be reduced in weight.

The bed side frame structure according to the present invention can be implemented by the following embodiments. That is, as shown in FIG. 2, the side frame 20 in this case is divided into a plurality of parts, and the joint member 21
Due to this, the structure is such that they are connected. The joint member 21 has a locking projection 22 corresponding to the shape of the locking groove 12.
The end surface of the side frame 20 to be connected is fitted into the locking projection 22 of the joint member 21 and screwed.

Even in such a structure, the welding process is not necessary, so that the process can be shortened.

As described above, according to the present invention, steps such as welding are unnecessary and the manufacturing process can be simplified, so that mass production is possible and manufacturing cost is also advantageous. Further, it is possible to reduce the weight because steel is not used as in the past.
