Description

  The present invention relates to a hook made of synthetic resin used in clothes and the like.

  A hook and a hook attached to an opening and closing part such as clothes is a well-known member composed of a hook (male part) and an eye (female part), and is usually formed of metal. In order to attach the metal part to the fabric, it is necessary to attach the metal part to the fabric, which increases the cost and sometimes unwinds the thread during use. Also, such metal hooks could hurt other clothes during washing.

  In order to avoid this, hooks made of synthetic resin have come to be used in brassieres or the like (see Japanese Patent Application Laid-Open No. 2004-176220).

  However, as far as the applicant knows, no hook made of synthetic resin has appeared as a hook for use in a portion where abdominal pressure is strongly applied, such as trousers and a skirt. The reason is probably that sufficient strength cannot be secured.

  An object of the present invention is to solve this problem and to provide a hook made of synthetic resin that can be used even in a portion where a strong pressure is applied.

The present invention that solves the above-mentioned object is a hook that is formed by bonding a synthetic resin hook and a synthetic resin eye to separate fabrics, and the hooks pass through the weave and stitches of the fabric. A front side and a back side integrally formed of a synthetic resin; and a front side and an extension extending from the base in a state of being lifted from the fabric , and the eye has a texture or stitch of the fabric. and the front side of the pocket which is integrally formed by synthetic resin to pass, have a support part of the rear surface side, the bottom of said pocket, characterized in that it is closed (claim 1)

  Preferably, a first engaging portion 23 for fixing the position is formed on the inner surface of the extension portion 22 of the hook, and the first engaging portion engages with the inner surface of the pocket front plate of the eye. Two engaging portions are formed (claim 2).

  Preferably, the cloth is a tape, and a plurality of the hooks and the eyes are formed at regular intervals.

  When the hook and the eye are bonded to the tape, the hook is bonded to the tape so that the extension portion is oriented in the longitudinal direction of the tape, and the pocket opening is oriented in the longitudinal direction of the tape. It is usual to bond the eye to the tape.

  Alternatively, the hook is bonded to the tape so that the extension is in the width direction of the tape, and the eye is bonded to the tape so that the pocket opening is in the longitudinal direction of the tape. (Claim 5).

  The hook of the present invention can also be used as a waist size extension tool for clothes formed by bonding a pair of synthetic resin hooks and synthetic resin eyes to the same fabric. In this extension tool, the hook includes a base portion on the front side and the back side integrally formed of a synthetic resin that passes through the fabric, and an extension portion that extends from the base portion in a state of being lifted from the fabric on the front side. The eye has a front pocket integrally formed of a synthetic resin that passes through the fabric and a back support portion, and the front surfaces of the hook and the eye are respectively on the front and back of the fabric. It is attached so that it may be located (Claim 6). The dough is preferably an elastic body (claim 7).

  Since the hook of the present invention is molded from a synthetic resin, it does not need to be attached with a thread as compared with a metal one, and can be designed to be thin or thick.

  Furthermore, since the eye and the hook are firmly bonded to the fabric, it has been found that the eye and the hook can be sufficiently used for a portion where abdominal pressure is strongly applied, such as an opening / closing portion of a trouser or a skirt. According to the measurement, a durability performance of 10 kg in the direction parallel to the fabric and 5 kg in the vertical direction was shown.

  By providing the first and second engaging portions according to claim 2, the portion is snap-fitted with a click and the position is temporarily fixed. This temporary fixation is such that it can be easily released by pulling with a finger.

  When a plurality of eyes and hooks are arranged on the tape as described in claim 3, a large number of items can be formed at a time. Moreover, even if it does not cut out one pair at a time, when using it for a belt, a curtain, etc., it can also be used with a tape form.

  Manufacture is easy when the hook and the eye are arranged as described in claim 4. If hooks and eyes are arranged as described in claim 4, post-processing is facilitated depending on the product.

  According to claim 6, there is provided one use of the hook and hook of the present invention. That is, it can also be used as a waist size extension tool for clothes formed by bonding a pair of synthetic resin hooks and synthetic resin eyes to the same fabric.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  As shown in FIGS. 1 and 2, the key hook 1 of this embodiment is formed of a synthetic resin as a pair of hooks (male parts) 2 and eyes (female parts) 3, and is joined to the fabrics 4 and 5. . As shown in FIG. 2, the usage method is the same as that of the prior art. Hereinafter, each component will be described in detail.

  3 to 6 show an embodiment of the hook 2. 3A is a front view, and FIG. 3B is a rear view. A plurality of tapes 4 are molded at the same interval by injection molding of a synthetic resin.

  The tape 4 fabric needs to be a fabric that allows the molten resin to pass through without being melted, and may be a woven fabric or a knitted fabric. For example, a polyester fabric may be employed. As the synthetic resin, a thermoplastic resin such as a polyacetal molten resin can be used. It is preferable to have a heat resistance of about 120 ° C.

  The hook 2 has the same contour on the front side and the back side of the tape, and both include a base portion 21 extending in the tape width direction and a tapered extension portion 22 extending in the vertical direction from the base portion. As shown in FIGS. 4 and 6, the extension 22 is lifted from the tape on the front side, and the extension 22 is inserted into the eye 3 during use. The back side is completely attached to the fabric. Since the purpose of the back side is to support the front side, the shape and size are not limited as long as it is possible.

  Further, for the purpose described later, a streak 23 (FIGS. 5 and 6) extending linearly in the tape width direction is formed on the inner surface of the extended portion 22 that floats on the front side.

  When the hook 2 is molded, the dough tape 4 through which molten resin passes and penetrates by molding pressure is disposed between upper and lower molds (not shown) in which a hook molding space is formed. Next, the dough tape 4 of the recessed portion 24 located inside the engagement protrusion of the hook 2 is sandwiched and fixed by the upper and lower molds. Thereafter, the synthetic resin is injected into the molding space, and the front surface side and the back surface side of the hook formed on both surfaces of the fabric tape are integrated with the synthetic resin that passes through the fabric tape.

  7 to 10 show an embodiment of eye 3. FIG. 3A is a front view, and FIG. 3B is a rear view. A plurality of tapes 5 are molded at the same interval by injection molding of synthetic resin.

  The tape 5 fabric needs to be a fabric that allows the molten resin to pass through without being melted, and may be a woven fabric or a knitted fabric. For example, a polyester fabric may be employed. As the synthetic resin, a thermoplastic resin such as a polyacetal molten resin can be used. It is preferable to have a heat resistance of about 120 ° C.

The eye 3 has an irregular contour on the front side and the back side of the tape 5. The left and right end portions 31 are slightly raised on the front side, and a pocket 33 is formed by the raised front plate 32 and the open space inside the upper portion. Pocket bottom that have been closed. As shown in FIGS. 8 and 10, a hook is inserted into this pocket during use. The back side is a square plate with a rounded corner, and is a support portion 36 that adheres to the fabric 5 entirely. The purpose of the back side support portion 36 is to support the front side, so that the shape and size are not limited as long as it is possible.

  Further, a streak-like groove 34 extending linearly in the width direction of the tape is formed on the inner surface of the front plate 32 that is lifted on the front side. When the hook 2 is inserted into the eye 3, the hook-like projection 23 (FIG. 10) and the eye-like groove 34 of the eye are snapped into a “click”, and the engagement is temporarily fixed and stabilized at that position. .

  When the eye 3 is molded, the fabric tape through which the molten resin passes and penetrates by molding pressure is disposed between upper and lower molds (not shown) in which an eye molding space is formed. Next, the dough tape in the recessed portion 35 located inside the engagement protrusion of the eye 3 is sandwiched and fixed by the upper and lower molds. Thereafter, the synthetic resin is injected into the molding space, and the front surface side and the back surface side of the eye formed on both surfaces of the fabric tape are integrated with the synthetic resin that passes through the fabric tape.

  The method of using the hook 1 is as described with reference to FIGS. When using a pair of hooks and eyes from the tape in the state of FIGS. 3 and 7, they are cut out and used.

  It can also be used as a belt or curtain whose length can be adjusted using a single hook and a plurality of eyes.

  When a pair of tape-like hooks 2A and eyes 3A are cut out and post-processed, it is preferable to form the hooks and eyes in the directions shown in FIGS. That is, the hook 2A is bonded to the tape so that the extension 22A faces the tape width direction, and the eye 3A is bonded to the tape so that the upper opening of the pocket 33A faces the longitudinal direction of the tape. However, since the molded product must be pulled out in the width direction, it is more difficult to arrange the mold and take out the molded product.

  13 to 15 show a third embodiment of the present invention. In this embodiment, as shown in FIG. 13, the hook 2 </ b> B and the eye 3 </ b> B are attached to a piece of tape 6 facing each other at a slight distance. The hook 2B and the eye 3B are the same as those in the first and second embodiments. Therefore, in the accompanying drawings, the same reference numerals as those in the first and second embodiments are given “B” to omit detailed description of each component.

  The hooks 2 </ b> B and the eyes 3 </ b> B are attached in such a relationship that the front sides of both are positioned on the front and back of the tape 6. That is, as shown in FIGS. 13 and 14, the front side of the hook 2 </ b> B is attached to the front surface of the tape 6, and the front side of the eye 3 </ b> B is attached to the back surface of the tape 6.

  In order to manufacture a single piece of tape 6 in which such male and female members coexist, it is economical to cut the tape 6 along the alternate long and short dash line after it is manufactured as a long one as shown in FIG. .

  The single piece of tape 6 in which the male and female members coexist can be used for various purposes. For example, the tape 6 can be used as a waist size extending tool 1B for clothes as shown in FIG.

  For example, when the waistline temporarily increases during a meal, after a meal, or during exercise, the original waist size of trousers or skirt may not be able to cope. In such a case, the waist size of the garment can be effectively increased by using the extension tool 1B.

  In order to attach the extension tool 1B to the trousers, it is only necessary to engage the eye 3B of the extension tool 1B with the original hook 7 as shown in FIG. Although the original hook 7 can no longer be used to connect the opening, the hook 2B of the extension 1B plays the role and can be connected to the original eye 8. Since the extension tool 1B is interposed between the original hook 7 and the eye 8, the waist size of the pants is extended by the extension tool.

  Preferably, when the tape constituting the extension tool 1B is an elastic body, for example, a rubber band, the tape itself can be extended, and a double extension effect can be obtained.
