Description

[Detailed Description of the Invention] <<Industrial Application Field>> The present invention relates to a belt-shaped locking tool equipped with a locking hook.

<<Prior Art>> An example of such a conventional locking device is shown in FIGS. 5 and 6. In the figure, the locking tool 1
is constructed by sewing both ends of a longer webbing 3 to both ends of the rubber belt 2, leaving the middle part slack, attaching a hook 4 to one end, and forming a mounting hole 5 in the other end. be done. The locking tool 1 configured in this way is used to temporarily connect two members, and is fixed to one of the members to be locked with a bolt or the like through the mounting hole 5, and A locking device for locking the hook 4 is attached to the other member to be locked. When joining the two members, there will be variations in the distance between the hook 4 and this locked tool, so this variation is absorbed by stretching the rubber belt 2, and both members are pressed into contact to prevent vibration. It is held in Note that excessive elongation of the rubber belt 2 is prevented by the webbing 3.

<<Problems to be solved by the invention>> However, although such a fastener 1 can absorb variations between the two members by elongating the rubber belt 2, the webbing 3 is normally in a slack state. There was a problem with the appearance that it looked bad. Furthermore, in the manufacturing process of the locking tool 1, both ends of the webbing 3 had to be sewn together, which increased the number of man-hours.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide an improved locking device that can improve the appearance and simplify manufacturing steps.

<Means for solving the problem> The locking device according to this invention folds back an elastic belt and a non-elastic belt with the non-elastic belt on the outside, and connects the outer non-elastic belt and the inner elastic belt at the folded part. It is characterized in that both ends of the elastic belt are joined with a predetermined gap between them, and a locking hook is inserted into the inside of the folded elastic belt.

<<Operation>> This locking tool is fixed to one member with a bolt or the like through a mounting hole formed at its base end,
A locking tool is attached to the other member to be locked, and the two members are coupled by locking a hook provided on the locking tool to the locking tool.

<<Example>> FIG. 1 shows an example of this invention. This locking device 10 is composed of a webbing 11 which is an inelastic belt, a rubber belt 12 which is an elastic belt, and a retaining ring 13 which is a hook.

This locking tool 10 is made as follows.
First, the rubber belt 12 is folded into a bag with its center part turned back, and the webbing 11, which is longer than the rubber belt 12, is stacked on the outside of the rubber belt 12, and one end portions 11a and 12a of each are aligned and folded into a bag. Then, as shown in FIG. 2, the other end 11b of the webbing 11 is folded over the other end 12b of the rubber belt 12 so that a predetermined interval d is left between each folding position of the webbing 11 and the rubber belt 12. Then, both ends of the webbing 11 and the rubber belt 12 are overlapped and sewn together using a sewing machine or the like.
An attachment hole 14 is formed in the sutured portion. At this time, in order to make the stitching state stronger, the other end 11b of the webbing 11 is attached to the other end 11b of the rubber belt 12.
2b, both ends of the webbing 11 and the rubber belt 12 may simply be aligned and sewn together. Next, the D-shaped retaining ring 13 is inserted inside the rubber belt 12 so as to enclose the rubber belt 12 and the webbing 11.

The locking tool 10 formed in this way is the third
As shown in the figure, this locking tool 10 is fixed to one member _S1 to be locked by a bolt B through its mounting hole 14. Then, the other member S ₂ to be locked
A locked tool F that engages with the retaining ring 13 of the locking tool 10 is fixed to the locking tool 10, and the engagement between the retaining ring 13 and the locked tool F causes both members S ₁ and S ₂ to be connected to each other. Join. If there is variation in the positional distance between the retaining ring 13 and the locked tool F, this variation is absorbed by stretching the rubber belt 12, and excessive stretching of the rubber belt 12 is prevented by the webbing 11. Therefore, the distance d provided between the webbing 11 and the rubber belt 12 at their folded positions is determined by how much the rubber belt 12 is stretched.

In this way, the locking tool 10 has a structure in which only the rubber belt 12 expands and contracts inside the double-folded webbing 11, so the length of the webbing 11 does not change.

FIG. 4 shows an example in which the locking device 10 according to this invention is applied to a locking device for a folding seat of a one-box car. The folding seat 15 constituting the third seat is constructed so that not only a seat back 16 can be folded onto the upper surface of the seat cushion 17, but also rear legs 18 can be folded onto the lower surface of the seat cushion 17. The front legs 19 are hinged to the floor 20 via brackets 21. When the seat bag 16 and rear legs 18 are folded into the seat cushion 17 and the seat cushion is tilted forward, the seat 15 is folded behind the second seat 22 as shown. The locking device 10 is fixed to the side of the seat back of the second seat 22, and the folding seat 15
A hook-shaped hook F serving as a locking device is attached to the side of the seat bag 16, and this state is maintained by locking the retaining ring 13 of the locking device 10 to the hook F.

Although webbing is used as the non-elastic belt in this embodiment, non-elastic materials such as leather, metal, hard rubber, synthetic resin, etc. can also be used. Further, although a D-ring shaped retaining ring is used for the hook, the retaining ring is not limited to the D-shaped retaining ring, but may be O-shaped, and even a normal hook-shaped hook can be attached to obtain the same effect.

<<Effects of the invention>> As described above, the fastening device according to this invention overlaps an inelastic belt and an elastic belt, folds them into a bag with the inelastic belt facing outward, and overlaps and joins both ends of each. At the same time, a locking hook is attached to an elastic belt, and the structure is such that the elastic belt expands and contracts inside the folded inelastic belt, so that the outer inelastic belt always stays on the inside of the folded inelastic belt. Maintains a certain shape and improves appearance. Furthermore, since only one joint is required in manufacturing, the number of man-hours can be reduced.
