Abstract

Clamp elements (4) are formed from a shape memory material. The material is made to memorize a shape at its transformation temperature as a shape where a gap between opening end portions (4a, 4a) is narrowed. After an airtight waterproof slide fastener (1) is closed at a temperature other than the transformation temperature, external environment of the airtight waterproof slide fastener (1) is set to the transformation temperature of the shape memory material. As a result, the opening end portions (4a, 4a) are shifted in the directions of the arrows so that the shape of the clamp elements (4) is returned to the shape at the transformation temperature. This causes the clamp elements (4) to deform in the direction to press a pressure contact face (14) between waterproof tapes (2), enhancing airtight waterproof property as a function of the airtight waterproof slide fastener (1).

The flexible covering layers 56 of the edge contact areas 57 are brought into close contact with each other by the pressing operation of the watertight zippers 50 at the three engagement positions, and a watertight state is ensured.

In the seal fastener structure disclosed in Japanese Patent Application Laid-Open No. Hei 6-181805, as shown in FIG. 23, a band-shaped occlusal ridge 6 2 having a bulging engagement portion 61 at the tip is provided. Are formed along one edge of the sheet body 60. In addition, a band-shaped occlusal groove 63 engaging with the occlusal ridge 62 is formed of a rubber-like elastic body and is formed along the edge of the other sheet member. The occlusal ridge portion 62 and the occlusal groove 63 form a band-shaped occlusal portion 64, forming a seal fastener structure. The occlusal ridges 62 are embedded with an inserted insert 65 made of a linear spring material and having a corrugated plane, and the occlusal ridges 62 are given rigidity in the occlusal direction. Further, a sandwiching insert 66 made of a linear spring material and having substantially no cross-section is buried in the outer peripheral portion of the occlusal groove 63, and the opening end of the occlusal portion 64 is embedded. A spring clamping force is applied between them.

In the above-mentioned slide fastener type of the airtight waterproof zipper of the prior art, the waterproof tape 41 and the watertight zipper support tapes 51 and 52 are brought into close contact with each other due to the pressing operation when the engaging teeth are engaged, so that the airtight waterproof state is achieved. Is secured. In the case of the rail fastener type, the occlusal ridges 6 2 are formed by the holding force of the pinch inserts 6 and the elastic force of the rubbery elastic body constituting the occlusal grooves 63. The seal fastener is kept watertight or airtight by holding the bulging engagement portion 61.

In other words, in these airtight waterproof fasteners, the pressing force and the holding force for maintaining the airtight and waterproof state are performed only by the pressing force generated by the engagement of the engagement teeth and the holding force at the bite portion. Other additional pressing force and holding force are not acting. For this reason, in order to obtain the desired pressing force and holding force, it is necessary to strongly engage or hold the engaging teeth and the occlusal part by sliding the slider, and the sliding resistance of the slider is large. Therefore, a strong pulling force is required to slide the slider.

An object of the present invention is to provide an airtight and waterproof fastener capable of reducing the pulling force of a slider and reliably ensuring a pressing force and a holding force for maintaining a watertight or airtight state by a new means. It is an object. Disclosure of the invention

In order to achieve the above object, a first basic configuration of the present invention is a hermetic waterproof zipper, wherein the hermetic waterproof zipper is provided with an assisting means for urging in a direction to increase hermetic waterproofness. Sex fasteners.

As the fastener in the present invention, a slide fastener, a rail fastener, or the like that can be opened and closed by a slider can be used. Examples of the slide fastener include a type in which a service tooth is provided between a fastener tape and a waterproof tape, a type in which a fastener tape and a waterproof tape are joined and a service tooth is provided on the fastener tape side, and a fastener tape. And the waterproof tape are bonded to each other so that the teeth are arranged on both sides of the tape. The present invention can be applied to a slide fastener known as an airtight waterproof fastener. It is. In addition, a well-known rail The present invention can be applied to snares.

By using the pressing force or the holding force assisted by the subsidy means, the pressing force or the holding force by the working teeth and the occlusal part itself can be reduced, and the pulling force of the slider can be reduced accordingly. become able to. Alternatively, the pressing force and the holding force for maintaining the watertight or airtight state of the airtight waterproof fastener can be further increased by the pressing force or the holding force assisted by the subsidizing means. In this case, by pulling the slider with a pulling force equivalent to the pulling force applied to the conventional slider, the airtight and waterproof state of the airtight and waterproof fastener of the present invention can be greatly improved.

The subsidizing means can be constituted by using a shape element for the clamp element for fixing the working teeth to the tape, the working teeth or the female member of the rail fastener. Moreover, by setting the use temperature of the airtight waterproof fastener to a temperature range including the transformation temperature of the shape memory material, the shape memory material can be deformed in a direction in which the pressure contact surfaces of the tapes are further brought into close contact with each other, With the aid, the pressing force or holding force of the airtight waterproof fastener can be increased. Unless otherwise specified, the tape is used in the present specification as including a fastener tape, a waterproof tape, and the like.

In addition, the temperature at which the airtight waterproof fastener is opened and closed is made different from the operating temperature of the airtight waterproof fastener that maintains the watertight and airtight state, that is, the temperature range including the transformation temperature of the shape memory material. However, the pulling force for pulling the slider that opens and closes the airtight waterproof fastener can be reduced.

That is, at the temperature at which the airtight waterproof fastener is opened and closed, the shape memory material is easily deformed by external stress, so the sliding resistance of the slider It becomes possible to reduce the pulling force of pulling the slider by deforming to a shape that reduces the force. Conversely, at the operating temperature of the airtight waterproof fastener that maintains the watertight and airtight state, it can be returned to a shape that increases the pressing force or holding force of the airtight waterproof fastener.

As the shape memory material, 开 shape memory alloy, shape memory polymer, etc. can be used.After deforming the shape memory material, the shape memory material returns to the original memorized shape by warming to the transformation temperature or higher. Properties can be used. In addition, by using a bidirectional shape memory material, two types of shapes, that is, when heated and when cooled, can be stored. By raising or lowering the temperature, the temperature can be returned to the transformation temperature, and the changed shape can be returned to the shape memorized by the transformation temperature. By using this property for IJ, it is possible to increase or decrease the pressing force or holding force of the airtight waterproof fastener.

Furthermore, the shape memory material may be deformed at a temperature equal to or higher than the transformation temperature of the shape memory material, and the super elastic property of the shape memory material immediately returning to the original shape by removing the deformed force may be used. it can.

That is, a female member of a clamp element, a working tooth, or a rail fastener is formed of a shape memory material, and at a transformation temperature of the shape memory material, the shape of the direction in which the press-contact portions of the tapes in the airtight waterproof fastener are further brought into close contact with each other. Store it in the shape storage material. The temperature at which the airtight waterproof fastener is opened and closed is set to a temperature equal to or higher than the normal temperature of the shape memory material. Thus, after the airtight waterproof fastener is closed, the above-described superelastic property can be utilized, and the shape of the shape memory material is returned in a direction in which the press-contact portions of the tapes are further adhered to each other. As a result, the pressing force or the holding force of the airtight waterproof fastener can be increased.

As a modification of the subsidy means, a tape containing a magnetic material can be used as the tape provided on the airtight waterproof fastener. Contains magnetic material The tape can be made of a material containing magnetic rubber, magnetic resin, magnetic powder, or the like. Further, by making the portion where the tapes are pressed against each other thicker than other portions of the tape, the magnetic attraction force at the portions where the tapes are pressed against each other can be increased.

Further, a magnetic material can be attached to at least one of the surfaces of the airtight waterproof zipper where the tapes are pressed against each other. A magnetic material or a magnetic substance can be attached to the other surface. As the magnetic material, a sheet-like flat magnet, a permanent magnet, a magnetic wire, or the like may be attached to the surface where the tapes are pressed against each other by an appropriate attaching means such as adhesion or welding, or the tape may be attached to the surface of the tape. The tape may be built in the pressure contact surface, or the tape itself may be formed using a flexible and waterproof material containing magnetic rubber, magnetic resin, or magnetic powder. .

In addition, a magnetic neo may be attached to one of the pressure contact surfaces of the tape, and a magnetic material attracted by the magnetic material may be attached to the other pressure contact surface. As the magnetic material, a metal plate, a metal powder, a metal net, a metal wire, or the like that is magnetically attracted can be used.

As another modification of the subsidizing means, a micro suction cup can be formed on one of the surfaces of the tapes provided on the airtight waterproof zipper where the tapes are pressed against each other. The micro suction cup may be constituted by a micro suction cup layer having a myriad of fine concave depressions, and the micro suction cup layer may be attached to one of the surfaces where the tapes are pressed against each other using a known attachment means. At this time, it is necessary to make the pressure contact surface of the other tape facing the micro sucker a smooth surface in order to extract the suction force of the mouth suction cup.

Micro suction cups can be shelled and peeled on any smooth surface, and can be shelled from low to high temperatures. Also, despite the surface being soft, there should be no wrapping around the Γ: be able to. For this reason, it becomes possible to impart watertightness to airtightness on the surface of the airtight waterproof fastener where the tapes are pressed against each other.

As another modified example of the subsidizing means, an adhesive material can be formed on at least one of the surfaces of the airtight and waterproof fasteners where the tapes are pressed against each other. As the adhesive, it is desirable to use an adhesive that does not reduce the adhesive strength due to a liquid or gas using an airtight waterproof fastener. In addition, it is desirable to use an adhesive that does not reduce the adhesive strength even if the adhesion and peeling are repeated, and that the adhesive surface of the other tape to be bonded with the adhesive is repeatedly bonded and peeled. It is desirable to form it on a smooth surface or a concave-convex surface having fine projections so that it can be performed.

Further, as another example of the subsidy means, an electromagnetic coil can be inserted in the male and female members of the rail fastener. By magnetizing or non-magnetizing the electromagnetic coil, the holding force between the male and female members of the rail fastener can be increased or decreased.

Electricity to excite the electromagnetic coil? The switch for connecting and disconnecting the power source and the power source can be provided on the rail fastener or on the adherend to which the rail fastener is to be attached. When the adherend can be installed such as a tank, tent, air dome, etc., an external power supply can be connected to the electromagnetic coil. In addition, if the adherend is used as a dive or the like, an external power source can be separately held.

As another modified example of the subscribing means, an electromagnetic coil may be wired in one of the male and female members of the rail fastener, and a magnetic material or a magnetic material may be provided in the other of the male and female members. In this case, since the electromagnetic coil can be arranged on one of the male and female members, the magnetic circuit configuration including the electromagnetic coil can be configured on only one side of the rail fastener, thereby simplifying the magnetic circuit. That it can.

The magnetic material to be disposed inside the other female or male member without the electromagnetic coil is a waterproof tape or fastener tape using a flexible and waterproof material containing magnetic rubber, magnetic resin, or magnetic powder. Etc. can also be formed. The magnetic material can also be formed by attaching a magnet, a magnetic wire, or the like to the contact surface between the male member and the female member, or by incorporating the magnet member in the contact surface.

Further, the magnetic material that is magnetically attracted by the electromagnetic coil can be formed of a metal plate, metal powder, a metal net, a metal wire, or the like, and the magnetic material is provided on the contact surface between the male member and the female member. It can be mounted or built into the abutment surface. Brief Description of Drawings
