Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a joint structure for assembly members used when assembling assembly members in sectional panels, frames, furniture, etc.

(Prior Art) Bolts and nuts have conventionally been most widely used when assembling components for assembling panels, display frames, or assembling furniture such as steel desks. Then, after aligning the abutting walls of both assembly members and aligning the holes provided in both abutting walls to form a penetration part that penetrates both abutting walls, a bolt is inserted into this penetration part. The assembly is carried out by screwing a nut onto the bolt and fastening both abutting walls.

(Problem to be solved by the invention) However, in the above conventional example, tools such as spanners and drivers are required to tighten the bolt and nut, and when tightening using these tools, the bolt or nut is moved around the axis. There is a problem in that the fastening operation requires a lot of time and effort because the turning operation has to be performed many times. Similarly, it takes time and effort to disassemble the assembled components.

Furthermore, since the fastening operation is performed by the above-mentioned rotational operation for each fastening point, there is also a problem that the fastening force varies depending on the fastening point.

SUMMARY OF THE INVENTION In view of the above problems, it is an object of the present invention to provide a joint structure for assembly members that can be easily fastened without using tools and that can easily equalize the fastening force.

(Means for Solving the Problems) The present invention provides holes that match each other in each of the abutting walls of assembly members that are combined with each other, and these holes form a through portion that penetrates both the abutting walls. The tip of the joint body, which has a flange at the base end and a hook portion whose tip bends toward the base end, is inserted into the penetration part, and the joint body is A pin is disposed such that the collar abuts around one end of the penetrating portion and the hook portion of the jigo point body projects outward from the other end of the penetrating portion, and the pin engages and is pivotally supported by the hook portion. The pin of a joint lever, which has cams on both sides of the pin, is latched onto the hook portion and pivoted, and by rotating the joint lever, the cam of the joint lever is pressed against the periphery of the other end of the penetrating portion. Accordingly, both abutting walls are fastened between the collar and the cam, thereby jointing both assembly members.

(Function) According to the above configuration, the pin of the joint lever is engaged and pivoted in the hook portion of the joint body, and both abutment walls are fastened between the collar and the cam by rotating the lever. be able to. When the joint lever is rotated, the tip of the hook portion is bent toward the proximal end, so that there is no risk that the pin will come out of the hook portion, and the fastening can be performed reliably.

Thereby, both assembly members can be assembled with a simple operation similar to a one-touch operation without using any tools.

Furthermore, since the fastening force is determined by the amount of rotation of the Jigointreba, it can be easily controlled, and the fastening force can be easily made uniform, so both assembly members can be assembled with uniform fastening force at each fastening location. Further, when disassembling the assembled assembly members, the same simple operation can be performed.

Note that if the above-mentioned fastening is performed with the bushing material inserted between the flange of the joint body and the hook part, the pressure acting on the abutting wall of both assembly members fastened between the flange and the cam will be reduced. It is possible to avoid damage or deformation of assembly members due to absorption of pressure, and it is also possible to smoothly rotate the joint lever 10 times during tightening or disassembly.

(Embodiment) The illustrated embodiment relates to an assembly type panel for a display, in which a panel plate 2 can be attached and detached from the front of the frame member 1 by means of permanent magnets 11 placed at appropriate positions on the frame member (&Il standing member) 1. It is designed to be installed.

Each of the side frame portions (abutting walls) 3 of the adjacent frame members l includes:
Holes 4a and 4b that match each other are provided to form a through portion 4 that penetrates both side frame portions 3.

A joint main body 7 shown in FIGS. 2 to 4 is inserted into this penetrating portion 4. As shown in FIG. This join l/wooden body 7 has a hook 15 at the base end and a hook 6 at the tip. The retaining groove 6a of the hook portion 6 has a predetermined dimension P such that the tip of the hook is directed toward the proximal end.
(Fig. 3) By bending, it is shaped to be eccentric to the right side in the figure. The collar 5 is formed in a size that comes into contact with the periphery 3a of one end of the penetrating portion 4,
In the case shown in the figure, a rubber packing (cushion material) 12 is interposed between the ff5 and the periphery 3a, and the cushioning action of the rubber packing is used to further ensure the fastening action between the joint body 7 and the giraffe lever 10 described below. I consider it a thing. Further, the hook portion 6 is formed so as to slightly protrude outward from the other end of the penetrating portion 4 when the joint main body 7 is inserted into the penetrating portion 4.

The joint lever 1 is attached to the hook part 6 of the joint body 7.
0 is entered. The joint lever 10 includes a pin 8 that engages with and pivots in the engagement groove 6a of the hook portion 6, and also includes a cam 9 that abuts against the periphery 3b of the other end of the through portion 4.

In this embodiment, as shown in FIG. 2, the cam 9 is formed of a pair of left and right eccentric disks that are eccentric with respect to the pin 8. 13 is a hole into which a rod or the like is inserted when the joint lever 10 is rotated. As shown in FIG. 3, after the pin 8 is engaged with the engagement groove 6a of the hook portion 6,
When the joint lever 10 is rotated upward by 90 degrees, the cam 9 presses against the periphery 3b of the other end of the through portion 4, and the both side frame portions 3 are pressed against the flange 5 and the cam 9, as shown in FIG. can be concluded between.

At this time, the elastic compression of both side frame portions 3 and the rubber packing 1
Due to the elastic compression of 2, the fastened state is maintained, and the joint lever 10 is also maintained in the posture shown in FIG.

The present invention can be constructed in various embodiments other than those shown in the above embodiments.

For example, as shown in FIG. 5, a shelf post 13 is interposed between the frame parts 3 on both sides, and the frame parts 3 on both sides are fastened using the jig-into main body 7 and the jigo-into lever 10. It is also possible.

Furthermore, the shape of the hook portion 6 of the joint body 7 and the shape of the cam 9 of the joint lever 10 are not limited to those shown in the above embodiments, but may be appropriately set according to the thickness dimensions of both abutting walls of the assembly members. Of course, it is possible to do so.

(Effects of the Invention) Since the present invention has the above-mentioned precepts, the following effects can be achieved.

■ Joint work between adjacent assembly members can be performed with a simple one-touch operation. In addition, disassembly of adjacent assembly parts can be performed with the same simple operation. Therefore, as shown in the above-mentioned embodiments, when the joint structure of the present invention is applied to an assembly type panel for a display, etc., which requires assembly and disassembly work within a short period of time, the effect is remarkable.

(2) Since the tightening force on both abutting walls of adjacent assembly members can be easily controlled, the assembly members can be joined with uniform tightening force.
