Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for mounting a shelf on a bookshelf. 2. Description of the Related Art A pair of front and rear columns which are fixed to each other are provided with through-holes, and the through-holes and the through-holes provided on a shelf board engaged between the columns are aligned with each other. There is a structure in which a nut is screwed and fastened to the tip of a bolt penetrated through the above to attach both ends of the shelf plate to the support. [0003] The above-mentioned conventional structure has been put to practical use as being applied to a so-called assembling type bookshelf. However, since both materials are tightened by bolts and nuts using the through holes, not only is there a limitation on the material of using steel materials, but the screwing between the bolts and nuts is loosened or they are rusted with each other. Inconvenience may occur. The present invention has been made in order to avoid such disadvantages of the prior art as much as possible and to provide a shelf plate attaching apparatus suitable for use in an assembling type bookshelf. [0005] A receiving piece is formed by projecting a fitting pin on the back surface of a base piece and a receiving piece on the front surface, respectively.
The receiving piece is inserted into a receiving hole provided on a facing surface of a pair of front and rear columns in a fixed relationship with each other, and the receiving piece projects from the facing surface of the pillar. And a hook having an L-shaped cross-section, which is provided at the end of the shelf plate, comprising a horizontal piece and a vertical piece, and the side edge of the hook piece is brought into contact with the surface of the base piece of the receiving piece. It is configured to oppose the position. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 shows an embodiment of an apparatus for mounting a shelf board on a book shelf according to the present invention. FIG.
4 is a longitudinal sectional view of FIG. 1, FIG. 3 is an exploded perspective view of main members, and FIG.
FIG. 2 is a schematic front view of a bookshelf. In the embodiment, a receiving piece A is assembled to a pair of front and rear columns 1 and 1a which are fixed to each other, and both ends of a shelf plate 3 are hooked on receiving pieces 2 of the receiving piece A. And shelf 3
Are detachably attached to the columns 1, 1a. The receiving piece A has a pair of upper and lower fitting pins 5, 5 on the back surface of the base piece 4, and a synthetic resin body (a metal body) having the receiving pieces 2 protruding on both sides of the front surface. Is not included). The receiving piece A of the embodiment has a pair of fitting pins 5, 5.
5, which are inserted into a pair (a set) of receiving holes 6, 6 provided in the columns 1, 1a so that the base piece 4, that is, the receiving piece A does not rotate on the horizontal axis. Therefore, there is no inconvenience even if only a single insertion pin 5 is used.
In addition, when the cross-section is square (the receiving hole 6 is also square in cross-section), even in the case of the single insertion pin 5, it is almost the same as that of the pair of insertion pins 5 and 5 as in the embodiment. Can prevent rotation. When the present invention is applied using a single fitting pin 5 (when the section is circular), the height of the vertical piece 7a on the tip side of the hooking piece 7 provided at both ends of the shelf 3 If the width is increased, the rotation of the insertion pin 5 due to the load applied to the shelf 3 can be prevented. The receiving piece A of the embodiment is provided with a pair of receiving pieces 2, 2 on the surface of a base piece 4. The receiving piece A, as shown in FIGS. Because the connection can be sequentially performed in the horizontal direction, it is a matter of course that there is no problem in applying the present invention even when a single shelf board is mounted in the horizontal direction. The pair of receiving pieces 2 and 2 of the embodiment have their lower ends integrated with each other via an intermediate piece 8 because the presence of the intermediate piece 8 increases the load resistance. When the function is omitted, the receiving piece 2 should be arranged at the center position of the base piece 1 in the left-right direction. The pillars 1 and 1a of the embodiment are made of a square tubular steel material, and the opposing surfaces 1 'and 1' of the pillars 1 and 1a.
Since the receiving hole 6 provided in a may have a structure in which the insertion pin 5 is inserted and the receiving piece A is supported in that state (from the viewpoint of assembling work), it is inconvenient to use wood. In addition, the number of the receiving holes 6 is, of course, one set corresponding to the number of the insertion pins 5 provided in the receiving piece A. Then, by appropriately providing the receiving holes 6 along the longitudinal (longitudinal) direction of the columns 1 and 1a, it is possible to obtain a bookshelf in which the number of positions of the shelf 3 can be freely selected. The shelf plate 3 is constructed by assembling both ends of a steel plate-made shelf main body 3A with end members 7A made of a steel plate provided with the above-mentioned hook pieces 7. The shelf main body 3A is made of wood. The end member 7A may be made of a steel material, or the two members 3A, 7A
May be integrated. In the case of the embodiment, the connecting piece 7 'connected to the hooking piece 7 of the end member 7A is fastened to the shelf body 3A with fastening screws 16, and the hooking pieces 7 are attached to both ends of the shelf body 3A. The hanging piece 7 is formed by suspending the vertical piece 7a at the tip of a horizontal (upper) piece 7b, and is provided immediately below the horizontal piece 7b, that is, between the vertical piece 7a and the shelf main body 3A. The space between them is a catching groove 9 for the receiving piece 2 at the lower end opening. Although the hooking pieces 7 are provided over the entire length of the width of the shelf 3, there is no inconvenience if the intermediate portion is omitted and provided only on both sides of the shelf 3. Further, the lower end edges 7'a of both sides of the vertical piece 7a of the hooking piece 7 are formed in an arc shape.
This is because the vertical piece 7a is easily inserted between the receiving pieces 2 and 2. Thus, the bookshelf of the embodiment is composed of the upper plate 18a,
A lower plate 18b and a pair of left and right supporting columns 1,1, 1a,
1a and the front and rear struts 1 and 1a at the intermediate portion are fastened to each other, and the front and rear struts 1 and 1a are fixedly connected to each other, and the shelf plate 3 is attached thereto. The receiving pins 2 of the receiving holes 6 and 6 provided in 1 'and 1'a are inserted and the receiving pieces 2 are projected from the opposing surfaces 1' and 1'a.
A hook 7 (a lateral piece 7b) provided at an end of the shelf 3 is hung on the receiving piece 2, and a side edge 17 of the hook 7 is received by the receiving piece A.
The device of the embodiment is obtained by arranging the base piece 4 so as to face the position in contact with the surface 4 ′ of the base piece 4. When the side edge 17 of the hooking piece 7 and the surface 4 'of the base piece 4 are arranged to be in contact with each other, the shelf 3
1a, so that there is no backlash because of the backing material, which increases the strength of assembling the bookshelf. However, the side edge 17 and the surface 4 'may be separated from each other. It is sufficient that the side edge 17 is in contact with the base piece 4 so that the receiving piece A can be prevented from being separated from the columns 1 and 1a. According to the present invention, which has the above-described configuration,
It is possible to provide a device which is suitable for use in an assembling type bookshelf and which can smoothly perform an attaching operation without a shelf board falling off from a support.
