Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a saddle for a long-distance vehicle, in which a cushion is placed on the upper surface of the saddle top in alignment with the buttocks.

Bicycle saddles used for long-distance cycling, bike riding, and motocross have a raised cushion on both sides of the tail edge to relieve pain and fatigue in the buttocks, and a groove in the center along the length of the cushion. It is designed to relieve pain in the coccyx of the buttocks.

In this saddle, both sides of the cushion material are raised and there is a groove in the longitudinal direction of the center, so in order to cover the saddle top and form a saddle, it is not possible to simply pull the periphery of the saddle top to the back side of the base and tighten it, as in the past. It is difficult to tension the saddle top because it is not possible to align the saddle top along the ridges and grooves of the material. Conventionally, therefore, adhesive is applied to the surface of the cushion placed on the base and the edge of the back side of the base, and the saddle top is manually pressed and adhered along the cushion surface.

The present invention provides a method for manufacturing a saddle that can be fixed to a saddle base by wrapping the saddle top along the ridges and grooves of the cushion material using the conventional saddle top tensioning method by introducing a simple skin pressing method. be.

The present invention will be specifically explained below based on the drawings.

First, as shown in FIG. 1, a cushion material 2 made of a foam sheet such as urethane or sponge is placed on a saddle base 1 whose surface is coated with adhesive.

The cushion material 2 has a tip 20 as shown in FIG.
The rear part is narrow, and the rear part is expanded on both sides, and the surface of the expanded rear part has a bulge 21 to provide thick cushioning, and a groove 22 is recessed in the center in the longitudinal direction.

An adhesive (for example, toluene bond, manufactured by Sharp Chemical Co., Ltd., trade name SR14 or 310K) is applied to the bottom and both side surfaces of the groove 22 and dried.

A cushion is provided on the cushion material 2, which has a curved surface that follows the unevenness of the cushion material 2 and the peripheral side surface of the saddle base 1, as shown in FIG. Cover with a wood cover.

Furthermore, move the saddle top 4 onto the cushion cover 3.
cover.

As shown in FIG. 4, adhesive is applied to the back surface of the saddle top 4 at a position facing the groove 22 of the cushion material 2, and is dried.

As is well known, a tightening wire 41 is sewn to the bag portion 40 at the periphery of the saddle top 4, and both ends of the wire 41 are exposed to the outside.

Thereafter, as shown in Fig. 7, the saddle base 1 is covered with the cushion material 2, the cushion cover 3, and the saddle top 4, then turned over and placed in the mold 6, and the presser mold 7 is applied to the back of the base 1 to compress it. The cushion material on the saddle base 1 and the cushion cover are compressed and deformed. At this time, the circumference of the saddle top 4 expands outward due to the shrinkage of the cushion material 2, creating a margin, so the tightening wire 41 enclosed in the bag 40 around the periphery of the saddle top 4 is squeezed to move the saddle top along the unevenness of the cushion material 2. At the same time, the wire 41 is fixed to the back side of the base 1 from above the saddle top 4 by wrapping the peripheral edge around the inside of the saddle base 1 and using a stopper 11 such as a claw or rivet placed inside the saddle base 1. let

Both ends of the tightening wire 41 are pulled together and tied together.

Finally, the center of the rear part of the saddle top 4 floating above the groove 22 is pressed down with the press die 5 as shown in FIG. By heating and applying adhesive strength, the rear center of the saddle top 4 is inserted into the cutout hole 3 of the cushion cover 3.
0 and adhered to the inner surface of the groove 22 of the cushion material 2 to form a groove 43 in the saddle top 4.

Further, the saddle cover 3 is provided to provide cushioning properties to the side surfaces of the saddle base, and is not essential to the implementation of the present invention.

As described above, the present invention forms the groove 22 having an adhesive layer at the center of the rear part, covers the saddle top with the cushion material on the saddle base 1, and tightens the wire 41 fitted around the periphery of the saddle top to attach the saddle top to the cushion material. In this state, the rear center of the saddle top is pressed and the back side of the saddle top is pushed into the groove 22 of the cushion material to bond it, so no skill is required to closely fit the saddle top along the unevenness of the cushion material. This eliminates the trouble of applying adhesive to the entire back surface of the saddle top 4 and manually pasting the saddle top to the saddle base as in the past, and greatly improves production efficiency.
