Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bookcase mounting structure for a bookcase which is preferably used for a steel bookcase or the like.

[0002]

2. Description of the Related Art In a book shelf made of steel or the like, it is widely practiced to suspend and attach a book support, which is used for the lower shelf, to the lower surface of the shelf.

As a conventional attachment structure for a book support, as shown in FIG. 7, an outer wall 11a, a bottom wall 11b and an inner wall 11 extending along the longitudinal direction at both widthwise edges of the shelf board 1.
A groove 11 surrounded by c is formed, and this groove 11 is formed on the inner wall 1
1c is opened to the book support mounting space A side through an opening 12 formed in a gap between the shelf board 1 and the book support 2 used for using the lower shelf board 1 is hung in the groove 11. I am trying to install it. Book support 2
Is a support surface S on which a book is attached, as shown in FIG.
U-shaped main body 21 that forms the
A first arm portion 22 and a second arm portion 23 that are located inside and project from the upper end of the main body portion 21 in a direction away from each other, and from the tips of the respective arm portions 22 and 23 are further orthogonal to the support surface S. The first engaging portion 24 and the second engaging portion 25 are substantially U-shaped and project in the direction.

The work of mounting the book support 2 is shown in FIG.
First, the first engaging portion 24 is first inserted into the groove 11 of the shelf board 1 through the corresponding opening portion 12, and thereafter, as shown by an imaginary line in FIG. 21 is contracted in a direction in which upper ends approach each other, and the second engaging portion 2
5 is inserted into the groove 11 of the shelf board 1 through the corresponding opening 12, and in that state, the main body portion 21 is elastically returned in the expanding direction so that both engaging portions 24 and 25 are in the corresponding groove 11. Are engaged with each other.

[0005]

However, such a mounting structure has a problem that the book support 2 is apt to rattle.

That is, when the book support 2 is fixed to the shelf board 1, when the main body 21 of the book support 2 is elastically returned in the expanding direction, both engaging portions 24 and 25 are fixed to the outer wall 11a of the corresponding groove 11. It is done only by being pressed closely. The height d2 of the second engaging portion 25 of the book support 2 is smaller than the height of the opening 12 because the second engaging portion 25 of the book support 2 needs to be inserted into the groove 11 through the opening 12 after the first engaging portion 24 is attached. Since it has to be set and is necessarily smaller than the height D of the groove, there is room for the second engaging portion 25 to move in the groove 11 in the vertical direction. This problem is improved by reducing the inner wall 11c of the groove 11 so that the height of the opening 12 approaches the height D of the groove, but the inner wall 11c prevents the second engaging portion 25 from slipping out of the groove 11. Fixing of the book support 2 becomes unstable because no work is performed. Also, in order to reduce the rattling, the first engaging portion 2 of the book support 2 is
It is necessary to make the height d1 of 4 and the height D of the groove correspond to each other, but the height d1 of the first engaging portion 24 is the same as that of the opening 12
Since the height is larger than the height, the charging work is complicated, and it is not realistic to make the dimensional relationship strict because the manufacturing cost increases. A spring member or the like is fixed to both the engaging portions 24 and 25 and elastically biased so as to engage with the groove 11 more firmly. Will be increased.

The present invention has been made in view of the above problems, and provides a book support mounting structure for a bookshelf capable of greatly reducing the rattling of the book support with a simple structure. It is an object.

[0008]

In order to achieve the above object, the present invention employs the following configuration.

That is, in the book support mounting structure according to the present invention, when the book support provided for the use of the lower shelf is hung and mounted on the lower surface of the shelf,

While opening to the book support mounting space side through the book support, a main body portion forming a support surface for attaching a book,
The first and second arm portions projecting from the upper end of the main body portion in a direction away from each other in the plane that is the same as or substantially parallel to the support surface, and the tip ends of the first and second arm portions are further described above. It comprises a first engaging portion and a second engaging portion projecting in a direction orthogonal to the support surface, and the first engaging portion of the book support is inserted into the groove of the shelf through the corresponding opening. After that, the main body portion is contracted in a direction in which the upper ends approach each other, and the second engaging portion is inserted into the groove of the shelf plate through the corresponding opening portion to elastically return the main body portion in the expanding direction. ,
In a book shelf mounting structure for a book shelf configured to engage the first and second engaging portions of the book support in the groove of the shelf board, the book support is attached to the shelf board in the book support. Part of the second arm portion is in contact with the lower surface of the shelf plate, and the lower end of the second engaging portion is in contact with the bottom wall of the groove, respectively.

At the same time, when the book support is attached to the shelf board, a part of the first arm portion of the book support is on the lower surface of the shelf board and the lower end of the first engaging portion is the groove. It may be configured to contact the bottom wall of each.

As a concrete embodiment of the present invention, there is one in which the entire book support is composed of a single elastic filament.

[0012]

With the book support mounting structure having such a structure, when the book support is mounted on the shelf board, a part of the second arm portion is located on the lower surface of the shelf board and the lower end of the second engaging portion is formed. By contacting the bottom wall with the bottom wall respectively, the rattling of the book support in the support surface direction (especially in the vertical direction) and the groove direction is greatly prevented to prevent the second engaging portion from moving in the vertical direction. Can be reduced. Further, if the first arm portion and the first engaging portion are also configured in the same manner, not only can the rattling be reduced more reliably, but also the height of the first engaging portion can be reduced. Since it is not necessary to correspond to the height of the first engaging portion, the height of the first engaging portion can be made smaller than that of the opening portion to facilitate the mounting work. Furthermore, since the engaging portion can be securely fixed even if the processing accuracy is low, and only the modification of the shape to the conventional configuration is required for implementing the present invention, the increase of the members and the manufacturing process / manufacturing cost. Can be manufactured without increasing

If the entire book support is made of a single elastic filament, the contact between the arms and the lower surface of the shelf and between the engaging portions and the bottom wall is ensured by utilizing the elastic biasing force. Therefore, not only can the rattling be reduced more reliably, but also bending can be performed, which facilitates the manufacture.
