Abstract

[PROBLEMS] To fix a plurality of sheets in a straight line without puncturing them and maintain waterproofness to some extent, and the binding line of the sheets can be deformed into a curve, can cope with irregular contents, and can be used repeatedly Provide economical and ecological seat fasteners.
SOLUTION: It is composed of three parts: a male type 1 that locks a plurality of sheets 4 in a stacked manner, a female type intermediate sleeve 2 that fits into the male type, and an outer sleeve 3 mounted on the intermediate sleeve. Of the locking means, the male mold is made by resin extrusion molding, and has a tunnel-like hole 6 in the longitudinal direction, and the curved shape can be maintained in the longitudinal direction by passing a wire through the hole.

Description

The present invention provides a novel fastening device for connecting sheet-shaped materials such as fabric, film, paper, and nonwoven fabric in a linear form.

In order to connect two sheets linearly, the respective materials must be connected by means such as sewing, high frequency, and rivets. For example, when one sheet is used as a bicycle cover, the four corners of the sheet are left over, and the sheet falls due to fluttering or shifting.
In addition, as a conventional main connection method, a method of tying two sheets with a string or mooring using a binding tool has been used. In any case, however, holes with eyelets were required in advance as in conventional curing sheets. For this reason, rainwater entered easily from the joint.

The two sheets can be linearly connected without making a cut or a hole in the sheet, and the waterproofness of the connecting portion can be maintained.
Furthermore, when a single sheet is covered as a cover on a three-dimensional object such as a bicycle or farm equipment, the sheet can be brought into close contact without being restricted by the content shape even if the contents change variously. When not in use, it can be returned to the sheet state when not in use and can be stored compactly.

When the sheet 4 is sandwiched between the projection 7 of the male extrusion molding resin 1 of the present invention and the middle sleeve 2 and the outer sleeve 3 is pushed in from above, the middle sleeve 2 moves to lock the male projection 7 across the sheet 4. . Further, the claw 10 of the outer sleeve slides and overlaps the peak position 9 of the middle sleeve from above, and the locking force is remarkably increased. When disconnecting, the outer sleeve 3 is pulled out, and the claw 10 of the outer sleeve moves through the crest 9 of the middle sleeve 3 to release the lock, so that the middle sleeve is opened and the folded claw 8 at the tip can easily come out of the projection 7.
The lock is easily released by one action of pulling out the sleeve 3.
If an aluminum wire is set in the aluminum wire tunnel 6 provided in advance in the extrusion mold, the shape retaining property is taken into consideration and the straightness can be fixed to an arbitrary curved shape.

The case where a vaporizable rust preventive sheet is used will be specifically described.
For example, in Hokkaido in winter, there is a period when bicycles are not used for a long time.
During this period, the bicycle rusts and the service life is significantly shortened.
Before the winter season, cover the surplus parts of the four corners or three places that are covered with a rust-proof sheet that covers the entire bicycle.
When the degree of bending of the inventive device is too large, it is possible to obtain straightness by adding hardness by passing an aluminum wire through a tunnel hole provided in a male shape in advance. On the other hand, the bottom of the rust-proof sheet hung on the bicycle can be adhered to the floor by bending the tip inward so that rust-proof gas does not escape out of the seat using a bend of aluminum wire.

It is a perspective view before locking the fastening tool comprised from three parts. It is a side view before locking the fastening tool comprised from three parts. It is A-A 'sectional drawing just before the locking of the fastening tool comprised from three parts. It is A-A 'sectional drawing at the time of completion of locking of the fastening tool comprised from three parts. The expansion perspective view of a middle sleeve.

The present invention is mainly composed of three parts, and is based on a fitting system in which a female part is fitted into a male base line and a plurality of sheets are bundled.
Not only can this fitting method be done with a simple movement of less labor and movement of the sleeve, but in order to obtain a reliable and strong holding force, a force that increases the locking pressure by creating a double connection of the female side is created. .

1. Male mold 2 of extrusion molding resin, middle sleeve 3, outer sleeve 4, sheet 5 to be used, convex stopper 6 for outer sleeve stop position, wire tunnel 7, male protrusion 8, middle sleeve end folding stopper 9, Middle sleeve switch purpose fold 10, outer stopper slide blade 11, middle sleeve notch guiding outer sleeve
