Description

[Detailed explanation of the idea] This invention relates to chain bands.

Conventionally, constructing a chain band requires many members and processes, and when it is made into a product, it is often extremely difficult for general consumers to adjust its length.

In view of such conventional drawbacks, this proposal proposes a bridge member,
It is an object of the present invention to provide a chain band which is composed of a slide member and a connecting member, and which improves productivity and allows a piece member to be easily attached and detached by sliding the slide member.

Next, this invention will be explained with reference to the drawings. That is, the present invention has a piece 6 provided with thin claws 2, 3, 4, and 5 facing each other inwardly at the four corners of the I-shaped plate 1, and a notch 9 provided in one direction of one end 8 of the square tube 7, and ,
A connecting member 1 having a hole 10 in the same direction as the notch 9
1, and a protrusion 14 on the bottom plate 13 of the concave groove plate 12,
It consists of a slide member 16 with a protruding plate 15 at one end of the bottom plate 13, and the slide member 16 is fitted into the connecting member 11 so that the protrusion 14 matches the hole 10, and the adjacent pieces 6 are inserted in parallel. thin nails 2, 3,
4 and 5 loosely fit into the openings 17 and 18 at both ends of the connecting member 11, and the protruding plate 1 of the slide member 16.
5 is a chain band that appears in the notch 9 and bites into the thin claws 3 and 5. Although the I-shaped plate 1 is thick, the thin claws 2, 3, 4, and 5 that are integral with it are formed thin by cutting the front and back surfaces thereof. This is to make the thickness of the piece 6 and the connecting member 11 constant. Moreover, if the piece 6 is formed to be slightly curved, the adhesion when worn will be improved. The connecting member 11 is connected to both sides 20 of the flat plate 19, as shown in FIG. 2B.
A half hole 22 of the hole 10 is provided at 21, and an L-shaped notch 23 is provided at one end symmetrically, and the broken line portion 2
By bending 4 and 25 inwardly, the connecting member 11 shown in FIG. 4A can be formed. Moreover, this connecting member 11 has a hole 10 in the square pipe.
Alternatively, it can also be obtained by machining the notch 9. When the projection 14 of the slide member 16 is circular, it is convenient to form the hole 10 in a gourd shape. This slide member 16 is fitted into the connecting member 11, and the slide member 1
The protrusion 14 of 6 matches the hole 10 of the connecting member 11. In this case, in the gourd-shaped hole 10, the expanded portion 26 is located at a position farther from the notch 9.
If the projections 14 are aligned with the projections 14, the projection plates 15 will not appear in the openings 18 formed by the notches 9 [FIG. 4A], so as shown in FIG. Insert the thin claws 2 and 4 of the piece 6 into one opening 17.
At the same time, the thin claws 3 and 5 relative to the thin claws 2 and 4 can be loosely fitted into the other opening 18 of the notch 9. Then, when the protrusion 14 is moved to the expansion part 27 located near the notch 9, the slide member 16 slides at the same time, and the protrusion plate 1
5 appears in the notch 9 [Fig. 4B], and this is the 5th
As shown in Figure B, it bites into the thin claws 3, 5 and restrains the thin claws 3, 5. In other words, the protruding plate 15 functions as a cover for the opening 18 formed by the notch 9, and serves to attach and detach pieces 6 adjacent in parallel. Therefore, as shown in FIG. 5B, when the protruding plate 15 closes the opening 18, the respective thin claws 2, 4,
3 and 5 are loosely fitted into the respective openings 17 and 18 and cannot be removed. Moreover, since the connecting member 11 is interposed between the pieces 6 with play, it has excellent flexibility even when a large number of pieces 6 are connected as shown in FIG. 6, and has excellent adhesion during use. . The gourd-shaped ends of the hole 10 restrict the movement range of the protrusion 14, and function as a stopper when the protrusion 14 abuts against it. As shown in FIG. 3C, the slide member 16 has a protrusion 14 driven in a predetermined position in advance.
In addition, both side portions 28 and 29 are bent in a U-shape along the broken line portion 30 in a direction opposite to the protrusion 14. As shown in FIG. 3D, the rod plate 31 is welded to the bottom plate 13 and protrudes in the opposite direction to the protrusion plate 15, and then this protrusion is bent to form a spring body 32 as shown in FIG. 3E. This is shown in Figure 4A,
When the slide member 11 is loosely fitted into the connecting member 11 as shown in B, the spring body 32 always presses the slide member 16 against the inner surface of the connecting member 11 so that the bottom plate 13 comes into surface contact with the slide member 11. This is effective in preventing the member 16 from falling off. From the above explanation, if the protrusion 14 is moved to the expanded portion 26 of the hole 10, the notch 9 will open and the thin claws 3 and 5 will be unrestrained, and therefore the thin claws are loosely inserted into the opening 17. 2 and 4 can also be freely removed to separate the piece 6.

According to the present invention, it is extremely easy to connect and disconnect the pieces 6 only by moving the projections 14, and since the chain band itself consists of only three members, it is highly productive and can be provided at low cost.
