Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a cloth tape,
The female and male snap fasteners made of synthetic resin, which are composed of female and male fitting parts arranged on the front side of the tape and fastening parts arranged on the back side and integrated with the fitting part, are placed at appropriate intervals. For tape-like snaps attached every other time.

[0002]

FIG. 17 shows a conventional tape-shaped snap 1.
A and 1B are shown. This kind of tape-shaped snap 1A, 1B
Is cut to an arbitrary length at the position of the tape 2, and FIG.
8, male and female tape-shaped snaps 1A, 1B
Sewn along the seams of the clothes so that they face each other,
Although it is used as a snap fastener, in the conventional tape-shaped snaps 1A and 1B, both the male and female fitting portions 3a and 3b and the fastening portions 4a and 4b arranged on both surfaces of the cloth tape 2 are provided. Was formed in a circular shape, and had the following disadvantages.

That is, when taking off clothes, the snap fastener is removed by holding the seam of the clothes, and as shown in FIG. 19, when the fitting of the female and male snap fasteners is released, the tape 2 is attached to the fastening portion. The tape 2 is bent in the width direction with the fulcrum 4a, 4b as a fulcrum, and the ends of the fastening portions 4a, 4b strongly press the back surface of the tape 2.

At this time, since the outer shapes of the fastening portions 4a and 4b are circular, the ends of the fastening portions 4a and 4b are positioned with respect to the warp (longitudinal fiber) a of the tape as shown in FIG. Thus, the warp a is in contact at one point so that the warp a becomes tangential, and the force concentrates on one point of the tape 2.

[0005] For this reason, the woven fibers are woven so that the warp a is pushed and bent at the ends (one point) of the fastening portions 4a and 4b from the state shown by the imaginary line to the state shown by the solid line in FIG. When the tape 2 is loosened and this is repeated frequently, a wavy wrinkle is formed at one end in the width direction of the tape 2, and the appearance becomes very irregular.

[0006]

DISCLOSURE OF THE INVENTION In view of the above situation, the present invention provides a method for disengaging female and male snap fasteners.
It is an object of the present invention to provide a tape-shaped snap which prevents a force from acting intensively on one point of the tape, thereby suppressing the looseness of the woven fibers of the tape and the wavy wrinkles of the tape due to the loosening.

[0007]

The technical means taken by the present invention to solve the above-mentioned problems are as follows.
That is, the present invention provides a female tape comprising a female and male fitting portion disposed on a front surface side of a cloth tape and a fastening portion disposed on the rear surface side and integrated with the fitting portion. In a female or male tape-shaped snap having male and female synthetic resin snap fasteners attached at appropriate intervals, the outer shape of the fitting portion is formed in a circular shape, and the outer shape of the fastening portion is parallel to the longitudinal direction of the tape. It is characterized in that it is formed in a shape having two opposing sides.

According to the above construction, when the female and male snap fasteners are disengaged from each other, the tape bends in the width direction with the fastening portion as a fulcrum, and the end of the fastening portion is strongly pressed against the back surface of the tape. Even so, since the outer shape of the fastening portion has a shape having two opposing sides parallel to the longitudinal direction of the tape, the end of the fastening portion comes into line contact with the side parallel to the longitudinal direction of the tape. The force applied to the tape by the ends of the fastening portions is dispersed.

Therefore, even if the snap fastener is repeatedly inserted and removed, the looseness of the woven fibers of the tape and the wavy wrinkles of the tape due to the loosening can be suppressed.

The above-mentioned effects are more remarkable as the length of the side parallel to the longitudinal direction of the tape is longer. Therefore, if the fastening portions have substantially the same dimensions, the outer shape of the fastening portion is hexagonal rather than octagonal. , Squares are more effective than hexagons. However,
If the outer shape of the fastening portion is too square, the tactile sensation when wearing clothes may be deteriorated. Therefore, as in the invention according to claim 2, the outer shape of the fastening portion is parallel to the longitudinal direction of the tape. It is practically preferable to form a hexagon having two opposite sides and a rounded corner.

[0011] When the fitting portion and the fastening portion on both sides of the tape are integrated, as in the invention according to claim 3,
A plurality of needle-like projections protruding from the back surface of the fitting portion are inserted from the top of the tape into through holes formed in the fastening portion, and the protruding tip is deformed by expanding (flanging) into one piece. And a form in which the fitting portion and the fastening portion are integrally formed by sandwiching the tape between the molding dies as in the invention according to claim 4. The present invention is also applicable to the format.

[0012]

Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1, 1A indicates a male tape-shaped snap, and 1B indicates a female tape-shaped snap. These tape-shaped snaps 1A and 1B are cut to an arbitrary length at the position of the tape 2, and sewn to face each other along the seam of the clothes as shown in FIG. 18, and used as snap fasteners. Is done.

And a projection 9 having an undercut 8 formed on the outer periphery. Then, the fitting portion 3a and the fastening portion 4a connect the four needle-like projections 5 projecting from the back surface of the fitting portion 3a to the through holes 6 formed in the fastening portion 4a from above the tape 2. It is integrated by inserting and penetrating and projecting its tip to expand and deform (flange).

The projecting portion 9 may be, for example, a solid column, a solid column having a diametral slit, a cylindrical column having a slit formed in the diametrical direction, or a cylindrical column having only the upper surface opened. Although various specific structures can be adopted, in this embodiment, as shown in FIG. 6, it is formed in a cylindrical shape having a hollow structure and only the lower surface is opened. Therefore, although the appearance is the same as the columnar shape of the solid structure, the amount of the synthetic resin to be used is small and it is economical, and the projections 9 have substantially uniform wall pressure. Irregular deformation due to sink of the synthetic resin at the time of cooling can be prevented, and the spring property is also improved. The fastening portion 4a is a hexagon having four through holes 6 formed at positions corresponding to the four needle-like projections 5 protruding from the back surface of the fitting portion 3a (a hexagon having a rounded corner portion). )
, But the outer shape is hexagonal and four needle-like projections 5
As long as four through holes 6 are formed at positions corresponding to the above, a ring shape with a hole at the center may be used.

The female tape-shaped snap 1B is shown in FIGS.
As shown in FIG. 13, a female fitting part 3b arranged on the front side of the long cloth tape 2 and a female fitting part 3b arranged on the back side of the long cloth tape 2 are integrated with the fitting part 3b. Fastening part 4b
Female fitting snap fasteners are attached at appropriate intervals. The outer shape of the fitting portion 3b is formed in a circular shape, and the outer shape of the fastening portion 4b is parallel to the longitudinal direction of the tape 2. It is formed in a hexagon having two opposing sides X and X and having a rounded corner.

The female fitting portion 3b has a concave portion 11 into which the projection 9 of the male fitting portion 3a fits in the center of a circular substrate portion 10 having four needle-like projections 5 projecting from the back surface. Formed
On the inner surface of the opening end of the concave portion 11, a bulging portion 12 which engages with the undercut portion 8 is formed. The fitting portion 3b and the fastening portion 4b are provided on the back surface of the fitting portion 3b.
The needle-like projections 5 are inserted from above the tape 2 into the through holes 6 formed in the fastening portions 4b, and the protruding tips are integrated by expanding and deforming (flanging) by hitting.

The bulging portion 12 formed on the inner surface of the opening end of the concave portion 11 may be continuous in a circular shape. However, in this embodiment, as shown in FIG. A plurality (six in the illustrated example) is defined by a portion 13 where the protrusion 12 does not exist, and the inner surface of the opening end of the concave portion 11 has a hexagonal shape or a shape similar thereto when viewed in plan. An annular groove 14 is formed on the outer periphery of the recess 11. This is because the bulging portion 12 has a radial depression 1.
3 is formed, and the annular groove 14 is formed on the outer periphery of the concave portion 11, whereby the elastic deformation in the radial direction is easily performed, and the spring property is improved.

The concave portion 11 may be a concave portion having a bottom, but in this embodiment, as shown in FIG. 12, the concave portion 11 has no bottom plate and penetrates vertically. this is,

Will be distributed. Therefore, the warp (longitudinal fiber) warp a of the tape is fixed to the fastening portions 4a, 4a.
As a result, the fibers are not pushed and bent at the end of b, and even if the snap fasteners are repeatedly engaged and disengaged, loosening of the woven fibers of the tape and wavy wrinkles of the tape can be suppressed.

Further, since the outer shape of the fastening portions 4a, 4b is a hexagon having two opposing sides X, X parallel to the longitudinal direction of the tapes 2, 2, the tape-like snaps 1A, 1B are connected to the joints of clothes. When sewn the tapes 2, 2 and 3, even if the longitudinal direction of the tapes 2 and 2 is sewn upside down, the above-mentioned effects can be obtained. Therefore, when sewing the tape-shaped snaps 1A and 1B, there is no need to worry about the upper and lower portions of the tapes 2 and 2, and the sewing operation is easy.

In the above example, the outer shape of the fastening portions 4a, 4b is formed in a hexagon having two opposing sides X, X parallel to the longitudinal direction of the tape 2 and having rounded corners. However, if it is a square having two opposing sides X, X parallel to the longitudinal direction of the tape 2, it may be a square or an octagon. In the above example, the four needle-like projections 5 protruding from the back surfaces of the fitting portions 3a and 3b are inserted from above the tape 2 into the through holes 6 formed in the fastening portions 4a and 4b. The fitting portions 3a, 3b are integrated with the fastening portions 4a, 4b by expanding and deforming (flanging) the protruding tip by hitting. However, as shown in FIG. 3 with tape in
