Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a frame member connector for a display case used when assembling a display case used in department stores, supermarkets, and other retail stores.

[0002]

[Prior Art]

 Conventionally, a display case used in a retail store or the like is constructed by connecting frame members made of light metal, synthetic resin, or the like, having an irregular cross section, with a connecting tool, and further connecting a wall such as a glass plate between the frame members. The mainstream is that the body is attached and assembled. Of the upper and lower frames, the left and right frame member connectors located at the contact points of the front or rear ends of the left and right lateral frames and the ends of the front frame or the rear frame are usually connected from the connector base. The one with connecting shafts protruding from three sides is used.

[0003]

[Problems to be solved by the device]

 In the above-mentioned conventional art, when the display case is, for example, a rectangular parallelepiped, the four frame member connectors located in the upper corners of the display case are frame member connectors that face each other on the left and right of the upper edge of the case. Are usually symmetric to each other, but they are constructed so that they cannot be turned over and used on either side. That is, they are only symmetrical when fixed to the right or left corners, respectively.

Therefore, they have to be separately manufactured and prepared, and such an increase in the number of parts increases the equipment cost because the number of types of molds increases, and the products are manufactured according to the production plan. When they are ordered, they have to adopt a high-mix low-volume production system, which lowers the yield and increases the manufacturing cost.

On the other hand, when packaging and storing the finished product, it is necessary to divide the product into many types, which causes a problem that the inventory space increases and the storage cost increases. The present invention has been made for the purpose of solving the above-mentioned drawbacks of the conventional technology and providing a frame member connecting device for a display case, which requires a small number of parts.

[0006]

[Means for solving the problem]

 The invention according to claim 1 is a frame member connector for a display case, which is used for connecting frame members to each other when assembling the display case by framing the frame member, and comprising: It is composed of a connector base located at a corner and a connecting shaft projecting from the connector base in the direction of the frame member, and the connector base has an attachment groove to which the wall of the display case can be attached. It is characterized in that the respective portions of the attachment groove and the connecting shaft that are provided are in plane symmetry with respect to a plane that passes through the inner and outer corners of the connector base body and bisects the same. The gist is the "frame member connector for the display case".

According to a second aspect of the present invention, "a plane where each part of the attachment groove and the two connecting shafts passes through the inner and outer corner portions of the connector base body and bisects the same is defined as a symmetry plane. The other connecting shaft is detachable so as to be in a plane-symmetrical relationship with each other at any corresponding position on the left and right with the plane of symmetry as a boundary. The frame material connector of the display case according to claim 1 "is a gist thereof.

That is, the invention as set forth in claim 1 is for connecting a connector base, which is a main part of the frame connector, and a wall of a case such as a glass plate which is provided on the connector base. With respect to the attachment groove and the connecting shaft that also projects from the connector base in three directions, the plane that passes through the inner and outer corners of the connector base and bisects the connector base is a plane of symmetry. If it is formed so that it is turned upside down on the basis of the plane of symmetry at the time of use, it can be used for either the upper corner or the lower corner of the display case. It becomes a frame material connecting tool.

According to the second aspect of the invention, one connecting shaft (usually the connecting shaft for connecting the front frame) is a connecting shaft that is asymmetric with respect to the plane of symmetry. Also, if it can be replaced so that it has a symmetrical relationship with the previous position when turned upside down, this single connecting shaft also has a symmetrical relationship from the beginning. It was set up like this. In any case, the aim is to reduce the number of parts as much as possible in this way.

In the invention according to claim 1 or 2, the inner and outer corners of the connector base refer to a corner that enters the inside of the case and an outer corner that opposes this corner. Further, these corner portions are not necessarily limited to those having an angular shape, and may be, for example, a curved surface or a flat surface having a curvature of a chamfered degree.

In the invention according to claim 1 or 2, there are innumerable planes that pass through the inner and outer corners of the connector base, but in the present invention, this plane divides the connector base into two equal parts. It is limited, so that this plane can be a plane of symmetry.

[0012]

[Action]

 The invention according to claim 1 comprises a connector base located at a corner portion of the display case and a connecting shaft projecting from the connector base in the direction of the frame member. An attachment groove to which the wall of the display case can be attached is provided, and each portion of the attachment groove and the connecting shaft has a plane that passes through the inner and outer corners of the connector base and bisects the same. Since the connecting base and the connecting shaft are turned upside down on the basis of the plane of symmetry, only the front and back are reversed. The member connector can be used for both the left and right corners or the lower corner.

According to a second aspect of the present invention, in the first aspect of the present invention, the attachment groove and the two connecting shafts are symmetrical with respect to a plane that passes through inner and outer corner portions of the connector base and bisects the same. Since the surface has a face-to-face relationship, if the inside is turned upside down as in the case of the device according to claim 1, only the front and back are reversed.

Further, since the remaining connecting shafts are detachable so as to be in a plane-symmetrical relationship with respect to any corresponding position on the left and right with the plane of symmetry as a boundary, they are attached to the connector base. Although it is asymmetric with respect to the plane of symmetry in the worn state, it is turned upside down and used in an asymmetric position when used as one corner of the case and when used as the other corner. It is possible to remove the connecting shaft from the base position and replace it with another position that is a face symmetry with respect to the base position, and in the end, the same action as the above two connecting shafts will be exhibited.
