Description

  In the present invention, an article shelf device that forms an outer frame by connecting an upper member and a lower member arranged above and below by a side member is connected to each other by a connecting bracket in a state in which the outer surfaces are in contact with each other. It is related with the connection structure of the goods shelf apparatus to perform.

  When an article shelf device such as a book shelf is installed, adjacent devices are connected to each other in order to improve installation stability, for example. As a structure for connecting the article shelf devices to each other, the connecting brackets are arranged over the outer side panels arranged in parallel to each other, and bolts are screwed to the respective outer side panels via the connecting brackets. In general, shelves are connected to each other. However, in this connection structure, the heads of the connection brackets and bolts are exposed to the outside, so that it is not necessarily preferable in view of the appearance quality.

  Considering these points, conventionally, a joint is formed between the upper panel that covers the upper surface of the article shelf device and the outer panel that covers the outer surface, and a slit is formed in the joint, and the connecting bracket is connected to the slit. There is provided a connection structure in which the connection bracket is attached to the lower surface of the upper panel with bolts in a state in which is inserted. According to this connection structure, since the slit for penetrating the connection bracket is provided in the joint, the slit does not stand out even when the article shelf device is installed alone. On the other hand, when connecting an article shelf device, a connection bracket penetrates into the slit and is not exposed to the outside. As a result, adjacent article shelf devices can be connected to each other without deteriorating the appearance quality (see, for example, Patent Document 1).

  In this case, simply attaching the connecting bracket penetrating from the slit of the joint to the lower surface of the upper panel with a bolt results in a state in which the tip of the connecting bracket and the head of the bolt protrude into the housing space of the article shelf device. When the article is taken in and out of the space, there is a possibility that the article may be damaged by interfering with the protruding connection bracket and the head of the bolt. For this reason, Patent Document 1 also provides a structure in which a recess is formed in a portion where the connection bracket is disposed at the edge of the top panel.

  According to such a connection structure, the head of the connection bracket and the bolt to which the connection bracket is screwed is accommodated in the recess, and there is no possibility that the connection bracket or the head of the bolt interferes when the article is taken in or out of the accommodation space. The situation that damages the article can be prevented.

Since the holes 34 are configured, it is possible to secure a desired fastening strength by sufficiently securing the screwing region of the mounting bolt 16 without increasing the plate thickness of the connecting bracket 30. However, the present invention is not limited to this, and the female screw hole 34 may be directly formed in the connection bracket 30.

  Further, in the above-described embodiment, when the upper surface of the mounting piece 33 is brought into contact with the lower surface of the first beam portion 122A2 in the rear lower horizontal frame member 122A, the upper surface of the base 31 is brought into contact with the lower surface of the frame main body 122A1. Since the connecting bracket 30 is configured so as to cause the height to protrude downward from the frame main body 122A1, the upper surface of the base 31 need not necessarily be in contact with the lower surface of the frame main body 122A1. Absent.

  Furthermore, in the above-described embodiment, the first beam portion 122A2 is provided over the entire length of the rear lower horizontal frame member 122A. However, the lower surface panel 121 can be placed and the connection bracket 30 can be mounted. If the mounting bolt 16 can be screwed into the female screw hole 34, the first beam portion 122A2 is not necessarily provided over the entire length of the rear lower horizontal frame member 122A.

  In the above-described embodiment, the rear lower horizontal frame member 122A is made of a metal material containing at least aluminum, and the frame main body 122A1 and the first beam portion 122A2 are integrally formed by an extrusion molding method. Although it can be easily formed without requiring work, the forming method is not necessarily limited to extrusion molding using a metal material containing aluminum.

  Furthermore, in the above-described embodiment, a distance corresponding to the plate thickness of the lower panel 121 is secured between the upper surface of the first beam portion 122A2 and the upper surface of the frame main body 122A1, and thus the upper surface of the frame main body 122A1 Although it can connect flatly without producing a level | step difference between the upper surfaces of the lower surface panel 121, this invention is not limited to this.
