Description

[Detailed description of the invention] "Industrial application field" This invention is a joining device for an assembled case in which each outer circumferential surface of a rectangular parallelepiped case is formed separately and these parts are joined so that they can be separated from each other. It is related to.

``Prior Art'' Conventionally, the technique of assembling a cage by joining grid-like mesh surfaces in a hexahedral shape has been widely used. engage with the same part, wrap a binding band around the same part,
Alternatively, a method is adopted in which a connecting plate is provided at the joint and the plates are screwed together using screws.

``Problems to be Solved by the Invention'' By the way, when assembling a casing by the above-mentioned means, for example, the engagement means or the binding band wrapping means may not be sufficient to secure the joints, causing the assembled casing to wobble or twist. Further, the screwing means has an unreasonable point that the assembly work is troublesome because it takes time and effort to screw and tighten the screws and nuts.

Therefore, it is an object of the present invention to eliminate the above-mentioned unreasonableness and to construct a sturdy assembled case that does not wobble or twist without requiring much effort in assembly work.

"Means for Solving the Problems" In order to achieve the above object, in an assembled case whose outer circumferential surface is made of a lattice surface, a matte-like shape is placed on the outer side of each joint edge of the four peripheral surfaces at the upper end. A joint protrusion having an engaging recess formed therein is attached, and a joint protrusion is attached to the inner side of the upper end of the joint, which is separately formed so that the two joint protrusions are overlapped with each other and fitted on the outside thereof. A downward locking piece that locks in the engagement recess is provided, and a tongue piece that is inserted and engaged between the two joint edges is provided extending inward from the lower end of the joint, and the joint is overlapped. It is constructed so that both protruding pieces are crimped and fixed by being fitted externally to both protruding pieces, and the four joint parts (four corners) on the four surrounding surfaces are joined and fixed by the above-mentioned crimping means. The assembled casing is constructed by fitting a bottom plate into the inner bottom portions of the four peripheral surfaces and engaging and fixing the lower edges of each surface.

"Operation" The joining protrusions attached to the outer same position of each joint edge on the four peripheral surfaces of the casing are overlapped, and a joining tool is attached to the outside thereof, and the engagement of the locking piece with the recess at the upper end of both protrusions and the lower end. When the tongue pieces are inserted and engaged between both joint edges in the above, both the joint protrusions are crimped and fixed by the joint tool, and the joint tool locks the joint protrusion pieces at the upper end and connects both the joint protrusions at the lower end. It engages between the joint edges and covers the outer peripheral surfaces of both protrusions and presses them, maintaining the crimped state between them and preventing them from coming off. As a result, the four corners are securely crimped and fixed to form a sturdy housing without wobbling or twisting.

"Embodiment" The assembled casing in the embodiment of the present invention will be explained with reference to the attached drawings.As shown in FIG.

The lower end horizontal wire 3c is inserted inward and provided internally as a joint edge with the bottom surface portion 5, and the upper side of the parallel vertical wire near the bent portion is connected with a horizontal wire 3d, and both ends of the horizontal wire 3d are projected. The protruding portion is formed into a U-shaped curved portion 3d' and protrudes from the front and back.

The right side part 4 is formed in a symmetrical shape with the left side part 3, and includes parallel vertical wire rods 4a..., upper end horizontal wire rods 4, etc.
b, a lower end horizontal wire 4c and a horizontal wire 4d having curved portions 4d' projecting from both ends.

The bottom part 5 has several longitudinal horizontal wire rods 5 arranged in parallel.
The equally spaced parts between both ends of a... and the two intermediate locations are connected by short vertical wire rods 5b..., and hook portions 5b' are curved at both front and rear ends of the intermediate vertical wire rod 5b. Both ends of each horizontal wire are bent upward into an inverted U-shape on the front and back sides to form hooks 5a' for the horizontal wires 3d and 4d on both side surfaces, and both ends of the horizontal wire at the center are bent upward into an inverted U-shape on the front and back sides. It is bent to form a placement piece 5a'' on the joint edge 4c of the bottom surface portion.

Then, a joint protrusion 6 having the same shape and having an engagement recess 6a at the upper end is attached outwardly at the same position on the outer side of the upper end of each joint edge of the four peripheral surfaces of the front, rear, left and right sides to form a joint. The overlapping state of the protrusions is shown in the circle at the left end A in FIG.

Also, as shown in the enlarged perspective view in Figure 4,
A separately formed box-shaped connector 7 is provided so as to fit onto the overlapping portion of both the protrusions 6, 6, and an upper end engagement recess for the protrusions 6, 6 is provided inside the upper end of the connector 7. At the same time, a downward hooking piece 7a that locks on the joint 6a is extended, and both joint edges 2 are extended inward from the lower end of the joint.
A tongue piece 7b is inserted into the gap between the tongues 3a and 3a and is locked to both joint edges.A tongue piece 7b is extended and the neck of the tongue piece is cut out to form a locking recess 7c. Then, as shown in the sectional view of FIG. 2, the hooking piece 7a of this connector 7 is inserted and locked into the engaging recess 6a of both protruding pieces, and then the lower part of the connector is pressed and the inner tongue piece is inserted and locked. 7b inwardly and insert it between both joint edges 2e and 3a to lock the locking recess 7.
