Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a connector for a chevron-shaped reinforcing frame material for reinforcing a box made of a material with poor rigidity such as a paper material or a thin plate material. This invention relates to an intermediate connector for connecting a new reinforcing frame to a longitudinally intermediate portion of a frame member.

(Prior art) As a conventional technology, there is a connector for a corner (Utility Application No. 140894/1989) previously filed by the present applicant.
It was hot.

To explain this with reference to FIG. 7, A is a corner connector, which has standing walls 1 and 2 that stand up in the vertical direction and are bent in an L-shape when viewed from above, and walls 1 and 2 that extend in the horizontal direction and have an L-shape when viewed from above. The bottom wall 3 bends to
4, connecting the outer bent edges 3a, 4a of the bottom walls 3, 4 to the lower parts 1a, 2a of the upright walls 1, 2, and communicating with each other in the left upright wall 1 and bottom wall 3. A left hollow part 5 having an L-shape in left side view with an open left end is formed, and a right hollow part with an L-shape in right side view which communicates with each other in the right standing wall 2 and bottom wall 4 and has an open right end. 6, and each standing wall 1, 2
An upright hollow part 7, which communicates with each other and has an open upper surface and has an L-shape in plan view, is formed in the bent part of the pipe.

(Problems to be Solved by the Invention) In the conventional device described above, eight corner connectors A of the same type are prepared, and these are arranged, for example, at each corner of the box, and each hollow part 5, 6, 7 By fitting the ends of the reinforcing frame members bent into chevron shapes, that is, the horizontal frames 30, 30 and the corner frame 35, to the respective corners, it is possible to quickly and easily frame these into a rectangular parallelepiped shape. This has the effect of increasing the bending rigidity of the connecting portion of the reinforcing frame material.

However, when the reinforcing frame materials are long, when they are framed into a rectangular parallelepiped shape using only the corner connectors A, it is not possible to prevent the bending rigidity of the reinforcing frame materials from decreasing. It is necessary to separately install a reinforcing frame material across the longitudinal middle part of the reinforcing material.

An object of the present invention is to obtain an intermediate connector for a chevron-shaped reinforcing frame material that can quickly and easily cross over a new reinforcing frame material to the longitudinal intermediate portion of the reinforcing frame material in such a case. .

(Means for Solving the Problems) In order to solve the above problems, the present invention is constructed as follows.

That is, a hollow mountain-shaped horizontal frame fitting body is provided which is bent in an L-shape when viewed from the side and extends laterally, and both ends are open, and the front part of the upright part forming the facing wall on the bent side of the horizontal frame fitting body is provided. A hollow mountain-shaped vertical frame fitting body bent in an L-shape in plan view and a hollow mountain-shaped cross frame fitting body bent in an L-shape in front view are provided on the wall and the bottom upper wall. The frame fitting body has one side facing the front wall of the upright portion and the other side extending forward and having at least its upper end opened, and the cross frame fitting body has one side facing the bottom top wall and the other side extending forward. The other side of the vertical frame fitting body is faced to the other side and the front end thereof is open.

(Function) Since the present invention is configured as described above, when the first reinforcing frame member formed in a chevron shape is fitted to the horizontal frame fitting body, the first reinforcing frame member is It passes through the inside of the horizontal frame fitting body, and a predetermined intermediate position thereof is located in the horizontal frame fitting body.

Furthermore, when a second reinforcing frame member formed in a chevron shape is fitted to the vertical frame fitting body, the second reinforcing frame member stands up in a direction perpendicular to the first reinforcing frame member, and , one side (rear side) of the fitting end faces the upright side of the first reinforcing frame material, and the fitting end (lower end)
will face the bottom side of the first reinforcing frame member.

Furthermore, when a third reinforcing frame member formed in a chevron shape is fitted to the cross frame fitting body, the third reinforcing frame member extends perpendicularly in the horizontal direction to the first reinforcing frame member. At the same time, the fitting end is located on one side (bottom surface).
faces the bottom side of the first reinforcing frame material, the other side (upright side) faces the other side (front side) of the second reinforcing frame material,
Further, the fitting end (side end) thereof faces one side (rear side) of the second reinforcing frame member.
