Description

[Detailed description of the invention] The present invention relates to a protector made of metal materials such as springs, and in particular, when a spring used in a vehicle seat etc. is connected to another spring or a fixed object, the squeak noise generated from the joint is solved. This invention relates to a spring protector that can prevent noise such as noise.

In a conventional vehicle seat, as shown in FIGS. 1 to 3, a wire spring 1 and a frame 2 are elastically connected by springs 3 and 4 to form a skeleton thereof.

That is, the spring 3 whose one end is fixed to the wire spring 1 and the spring 4 at the center of the seat are connected to the plate member 5 fixed to the frame 2.
It is locked by a locking part 6 stamped out above at the top, and is pressed from above, and is fixed by deformation of the locking part 6 as shown in FIG.

No matter how many layers are added to this sheet, a squeak will occur between the springs 3 and 4, or between the spring 3 and the wire spring 1, or between the locking part 6.

In order to prevent this noise from occurring, the surfaces of the springs 3 and 4 are coated with polyethylene, nylon, or the like.

However, if the contact parts between the springs 3 and 4 or between the springs 3 and 4 and the member that fixes them wear out and the coating peels off, the metal part will be exposed and the squeak will occur again. there were.

The present invention was made to eliminate the above-mentioned drawbacks of the prior art, and its purpose is to provide a protector for springs, etc., which is easy to assemble and which can prevent squeaks at the spring engagement part. The protector is integrally molded from synthetic resin, and has a first protector part that is approximately U-shaped and has a semicircular cross section, and a second protector part that has the same shape as the first protector part. a protector portion, a hinge portion that connects the first protector portion and the second protector portion to each other at their respective U-shaped curved portions, and the first protector that is bent and fitted together at the hinge portion. and a second protector part, and a U-shaped pipe-shaped part formed by the two combined protector parts is provided with a desired metal material such as a spring. The reason is that it is made to be inserted and held.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of the present invention will be explained in more detail with reference to the drawings.

In FIG. 5, the protector 10 is an integrally molded product of synthetic resin, and includes a first protector part 12 having a U-shape and a substantially semicircular cross-section, and a second protector part 13 having a similar shape. In these U-shaped curved parts,
The hinge portion 14 is symmetrically integrated with the hinge portion 14, which is protruded at a predetermined distance.

Engagement pawls 12a (locking means) are formed on the outside of the tip of the first protector section 12, and engagement claws 12a (locking means) are formed on the outside of the tip of the second protector section 12, which can be engaged with the engagement pawls 12a. Engagement holes 13a (locking means) are respectively formed.

Further, the hinge portion 14 is provided with a groove 14a to form a particularly thin portion, making it easy to bend.

With the structure described above, one side of the protector 10 of this embodiment, for example, the groove of the first protector part 12, is applied to the U-shaped part of the spring S called a zigzag spring or S-shaped spring, and the hinge part 14 to cover the groove of the second protector part 13 and insert the engaging claws 12a into the engaging holes 13a, both protector parts 12 and 13 are formed in a pipe shape around the spring S. , the protector 10 will sandwich the spring S.

Thereafter, as shown in FIG. 8, the spring S is fixed to the fixing member 17 from above the protector 10 using the locking part 16 formed by punching out a plate or the like.
The U-shaped part of is fixed with its entire circumference wrapped.

When a load is applied to the seat in this state, there is no friction between metals such as the spring S and the fixing member 17, and since the protector 10 is interposed on all friction surfaces, squeaks and other noises can be avoided. There is no possibility of abnormal noise occurring.

In the above explanation, an example was shown in which two springs are fixed to a fixing member as shown in FIG. It is also possible to fix the two springs to a fixed member so that they do not squeak.

Further, as shown in FIG. 5, the engaging claw 12a and the engaging hole 1
3a are provided on the outside of the tips of both protector parts 12 and 13, but it is also possible to provide them on the inside of the tips of both protector parts 12 and 13.

Furthermore, although the engaging claws 12a1 and the engaging hole portions 13a are provided as means for locking the protectors 12 and 13, other locking means such as a simple concave-convex fitting portion may also be used.

Further, in the above embodiment, a protector for a spring was described, but it may be made of a metal material other than a spring.

As described above, it goes without saying that the invention can be implemented with various modifications and improvements based on the knowledge of those skilled in the art without departing from the spirit of the invention.

As detailed above, in the protector according to the present invention,
Both protector parts and the hinge part are formed by integral molding of synthetic resin, and the U-shaped pipe-shaped part formed by both protector parts is designed to insert and hold springs, etc., so this protector No tools are required to assemble it to a spring, etc., and it can be bent and assembled with one touch, making it especially easy to assemble, and when a load is applied to the seat part. In addition, the generation of abnormal noises such as squeaks at the locking parts of springs, etc. is completely prevented, there is no risk of the squeaks occurring again due to friction, and it also works well as a stopper for removing springs, etc. Therefore, there is no need to apply a resin coating to the surface of the spring or the like as in the conventional method, and therefore, the problem of peeling off of the coating due to wear can be easily solved, and other excellent effects can be achieved.
