Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a knock-down type shelving device.

(Prior Art) Conventionally, the following types of shelf devices are known as this type. That is, it has a pair of left and right side plates arranged at a predetermined interval, and a plurality of shelf plates that can be cut at predetermined length positions and are secured to the inner surfaces of these side plates via joints. It is known that shelf devices are assembled by cutting shelf boards depending on the installation location.

(Assembling method of conventional device) A conventional shelf device was assembled as follows. That is, the shelf board is cut to a length corresponding to the installation location, and then joint tools are fixed to the left and right ends of the shelf board so that the front and back positions thereof are accurately determined,
After that, the shelf board is fixed to the side board by fitting screws through the screw insertion holes of the joint tool into the screw holes formed at the predetermined heights of the screw holes formed on the front and rear sides of the side board at a predetermined interval above and below, through the screw insertion holes of the joint tool. That's what I was doing.

(Disadvantages of the Prior Art) The conventional shelf device has the following disadvantages. In other words, unless the screw insertion hole of the joint tool matches the screw hole of the side plate, the shelf board cannot be installed, so it is essential to accurately determine the position of the joint tool with respect to the shelf board, as described above. . To explain in more detail, if the length of the shelf does not change, it is sufficient to clearly indicate the mounting position of the joint on both ends of the shelf, but this is not possible with knock-down type shelving devices. , I had to position each shelf board after cutting it. Therefore, there was a drawback that assembly work required time and effort.

(Purpose of the invention) This invention was made in order to eliminate the above-mentioned drawbacks, and the purpose of this invention is to provide a knock-down type shelf device that does not require positioning of joint tools after cutting the shelf board. be.

(Example) This invention will be described below based on an example shown in the drawings.

As shown in FIGS. 1 and 2, the shelf device main body 1 includes a pair of left and right side plates 2 arranged at a predetermined interval.
Screw holes 3 are formed at predetermined intervals vertically on the front and rear sides of the inner surface of these side plates 2, and screw holes 3 at predetermined length positions among these screw holes 3 are provided with screw holes as will be described later. The joint tools 4 attached to the shelf board 8 are screwed to each other, and these joint tools 4 are constructed as follows. That is, the joint tool 4 having an inverted L-shaped cross section has a vertical mounting edge 5 to the side plate 2 and a horizontal shelf receiving edge 6 that continues to this mounting edge 5, and the mounting edge 5 has a screw. An insertion hole 11 is formed, and an upward positioning convex portion 7 is formed on the shelf receiving edge 6.

As shown in FIG. 3, the shelf board 8 is divided into an uncut base 8A and a cut-and-removable part 8B that continues on one side of the base 8A, and is separated from the front and back of the lower surfaces of the base 8A and the cut-and-removable part 8B. A series of positioning grooves 9 are formed in the left and right portions.
As will be described later, the cut-and-removable part 8B
After the joint tool 4 is cut at a predetermined length position, the positioning protrusion 7 of the joint tool 4 is fitted into the positioning groove 9 and fixed with a screw 10. Note that the positioning groove 9 does not need to be formed on the entire front and rear sides of the lower surface of the base 8A;
It is sufficient that they are formed at least at the left and right ends of the front and rear portions of the lower surface of the base 8A, respectively, and the lengths of the base 8A and the cut-removable portion 8B of the shelf board 8 are arbitrarily determined. Furthermore, it goes without saying that the means for attaching the joint tool 4 to the side plate 2 and shelf board 8 is not limited to screws.

(Assembling method of example) The assembly method of the embodiment will be explained below.

First, the removable portion 8B of the shelf board 8 is cut at predetermined left and right positions, and the shelf board 8 is made to have a left and right length depending on the assembly location. Even if the shelf board 8 is cut in this way, the positioning grooves 9 will be located on the left and right sides of the shelf board 8, so the positioning protrusion 7 of the joint tool 4 can be fitted into these positioning grooves 9. Therefore, fit the positioning protrusion 7 of the joint tool 4 into the positioning groove 9 on the left and right ends, and then tighten the screw 10.
Stop by. After that, the joint tool 4 fixed on the shelf board 8 may be fixed on the side plate 2 in which the screw hole 3 is pre-drilled.

(Effects of the invention) As described above, according to this invention, the cutting and removable part 8B of the shelf board 8 that can be cut at a predetermined length position is provided with A long positioning groove 9 is formed, and the shelf board 8
Since it is not necessary to determine the attachment position of the joint tool 4 after cutting, the labor required for assembly work can be saved.
