Description

  The present invention relates to a slider for a slide fastener capable of reducing sound generated by contact between a slider body and a puller.

  Conventionally, a slide fastener is attached to the opening to easily open and close the opening of clothes, bags and the like. In general, a slide fastener has a plurality of fastener elements arranged in a row on opposite element mounting edges of left and right fastener tapes to form a pair of left and right fastener stringers, and a number of fasteners arranged on the obtained left and right fastener stringers The slider is inserted into the left and right element rows made up of elements.

  The slider includes a slider body that is inserted into the element row and a handle attached to the slider body. The slider fuselage is often made of metal, and generally, the upper and lower blades, the connecting pillar that connects the upper and lower blades at the slider front end, and the left and right side edges of the upper and / or lower blades. It has left and right flanges formed, and a handle attachment column erected on the upper blade surface (upper surface) along the slider front-rear direction (slider sliding direction).

  Left and right shoulders divided by connecting columns are formed on the front end side of the slider body, and a rear opening is formed on the rear end of the slider body. Further, a Y-shaped element guide passage that communicates the left and right shoulder openings and the rear opening is disposed between the upper and lower blades. The pull has a connecting portion for connecting one end to a pull attachment column provided on the slider body, and a knob portion disposed on the other end of the connecting portion.

  An example of a slide fastener having such a configuration is described in European Patent No. 761117 (Patent Document 1). As shown in FIG. 14, the slide fastener 71 described in Patent Document 1 is configured by inserting a slider 74 through an element row 73 of a pair of left and right fastener stringers 72. The slider 74 in Patent Document 1 includes a slider body 75 and a handle 76. The slider body 75 includes an upper wing plate, a lower wing plate, a connecting column, left and right flanges, and an inverted U-shaped pulling attachment column 75a. have.

  The handle 76 has a connecting body 77 and a knob 78, and the connecting body 77 has a first mounting portion 77a formed of a hole formed at one end thereof and an annular portion disposed at the other end. And a second mounting portion 77b made of a rim. In this case, for example, the connecting body 77 is hooked by inserting the first mounting portion 77a into the inverted U-shaped pulling attachment column 75a previously arranged in a cantilever state on the slider body 75, and then the connecting body 77 is attached to the pulling handle. The pull handle attachment column 75a is plastically deformed so as not to be detached from the column 75a, and is attached to the slider body 75.

  On the other hand, as shown in FIG. 15, the knob 78 has a first main body (front half) 78a, a second main body (back half) 78b, and the first and second main bodies 78a and 78b. And a neck portion 78c to be connected. A plurality of loops 78d constituting a surface fastener are formed on the first surface (inner surface) of the first main body portion 78a of the knob 78, and the first surface (inner surface) of the second main body portion 78b. Are formed with a plurality of hooks 78e constituting a hook-and-loop fastener.

  A knob 78 having a plurality of loops 78d and hooks 78e is formed after the first main body 78a or the second main body 78e is inserted into the second attachment portion (rim) 77b of the connecting body 77. The main body portion 78a and the second main body portion 78b are overlapped with each other, and the hook 78e of the second main body portion 78b is engaged with the loop 78d of the first main body portion 78a, thereby being attached to the connecting body 77.

  The slide fastener 71 of Patent Document 1 as described above can be manufactured at a lower cost than, for example, a slide fastener that uses a rivet to attach the knob 78. Moreover, the knob | pick part 78 can be easily formed in a desired shape, for example by cutting out a hook-and-loop fastener to a predetermined shape. For this reason, the knob | pick part 78 can arrange abundant variations, and also, various patterns, logos, etc. are provided on the surface and back surface (the 2nd surface of a 1st main part and a 2nd main part) of the pick part 78. It has an advantage that it can be easily attached by printing or the like.

  By the way, slide fasteners are generally used for openings such as clothes and bags, but in recent years, they have also been widely used for seat covers for seats installed in automobiles and the like. For example, Japanese Patent No. 3380150 (Patent Document 2) discloses a seat in which a slide fastener is used for a skin (seat cover) of a seat back.

  As shown in FIG. 16, the seat 81 described in Patent Document 2 includes two members, a seat cushion 82 and a seat back 83. Each of the members 82 and 83 includes a seat frame (not shown), a pad having a predetermined shape (not shown) fixed to the seat frame, and skins 86 and 87 covering the pads. The pad is formed of polyurethane or the like and has a cushioning property.

  In Patent Document 2, a cutout 88 is formed on the skin 87 of the seat back 83 upward from the lower end edge of the seat rear surface, and the skin rear surface portion 87a is separated into right and left via the cutout 88. It is formed as follows. The seat back 83 is sewn with a slide fastener 89 along a notch 88 formed in the skin rear surface portion 87a. By sliding the slider 92 of the slide fastener 89 downward, the right and left The notch 88 is closed by meshing the element 91.

  One end of the slide fastener 89 extends longer than the lower end edge 87b of the epidermis rear surface portion 87a, and one of the left and right fastener stringers extends from the epidermis end edge 87b. It is folded back to the back side of the skin 87 and sewn to the skin 87 in a state of being hidden from view from the outside.

  In such a seat 81 of Patent Document 2, the cover 87 is put on the pad of the seat back 83 in a state where the slide fastener 89 is opened and the skin rear surface 87a is separated into the left and right, and then the slider 92 is slid. By closing the slide fastener 89, it is possible to cover the pad 87 with a good appearance.

  In particular, in the seat 81 of Patent Document 2, one fastener stringer of the slide fastener 89 is sewn in a state in which a portion extending below the epidermal subcutaneous edge 87b is concealed on the back surface side of the epidermis. For this reason, when the slide fastener 89 is closed, the extended portion of the other fastener stringer is also folded back and concealed on the back side of the skin. Thereby, when the slide fastener 89 is in the closed state, the end portion on the extending portion side of the slide fastener 89 is held at a predetermined position on the skin back surface side.

Accordingly, the skin 87 covered with the pad of the seat 81 is pulled out from the back surface side of the skin fastener 89 even if, for example, a passenger's finger seated on the seat 81 is accidentally hooked on the slide fastener 89. hard. For this reason, the closed state of the slide fastener 89 can be stably maintained.
European Patent No. 761117 Japanese Patent No. 3380150

  In the conventional slide fastener such as Patent Document 1, the slider knob is configured with a belt-like body such as a woven fabric provided with a hook-and-loop fastener so that the handle can be easily picked, and the front and back surfaces of the knob are The slider is disposed so as to be transverse to the sliding direction of the slider. In addition, the slider connecting portion is rotated along the sliding direction of the slider around the first mounting portion on the slider body side so that the user can pick the knob and smoothly slide the slider along the element row. The slider body is movably supported. Further, the connecting portion is generally formed of a metal member that is hardly broken or the like in order to securely connect the slider body and the handle for a long period of time.

  As described above, in the conventional slide fastener, the slider handle is attached in consideration of the operability of the slider, but when the slider is not operated, the metallic slider body and the connecting portion of the handle are in contact with each other. There was a problem that an unpleasant metallic sound was generated. In addition, when the slide fastener is used for a seat cover of a car seat as in Patent Document 2, for example, the slider body and the puller frequently come into contact with each other due to vibrations when the car travels, and the slider also hangs. As a result, there is also a problem that a contact sound is generated because the slider body and the handle come into contact with other members such as a seat frame.

  In addition, the slider body and the handle are brought into contact with each other and the contact noise due to the contact with other members is generated to some extent by, for example, forming the connecting part of the slider body and the handle with a synthetic resin molded product. Although it can be reduced, in order to further improve the quality of the slide fastener, it has been desired to prevent contact noise more effectively.

  In addition, not only the slide fastener used for the seat cover of the seat as described above but also the contact sound is important to prevent the generation of the contact sound on the slider body and the handle without reducing the operability of the slider. There has also been a demand for slide fasteners used in baby clothes, infant clothes, nursing clothes and the like.

  Further, when the slide fastener 89 is used for the skin (seat cover) 87 of the automobile seat 81 as in Patent Document 2, the slide fastener 89 is closed and the slider 92 is concealed on the back side of the skin. For example, when the concealed portion of the slide fastener 89 (the portion extending from the subepidermal edge 87 b) is short, the slider 89 pulls around the slider body, and a part of the puller 87 is covered by the skin 87. Sometimes protrudes from the lower end edge 87b. Thus, when the handle of the slider 89 is exposed, it does not look good, and the slider is likely to be caught by another member, and the slider may be erroneously operated.

  The present invention has been made in view of the above-described conventional problems. A specific object of the present invention is to reduce the contact sound generated from the slider body and the handle without affecting the operability. The object is to provide a slider for a slide fastener that can prevent noise even when used for a seat cover or the like. Furthermore, when the slide fastener is used for a seat cover or the like of a seat, it is provided on the back side of the seat cover. An object of the present invention is to provide a slide fastener slider that can be surely concealed.

  In order to achieve the above object, the slider for a slide fastener provided by the present invention has, as a basic structure, an upper wing plate and a lower wing plate connected to each other at the front end portion on the shoulder opening side by a guide column, and is connected to the rear end. A slider for a slide fastener comprising a slider body having a mouth, and is bridged between left and right leg portions erected from the upper wing plate and spaced from each other in a transverse direction of the slider body and upper end portions of the left and right leg portions. And a bridge-shaped pull attachment column formed integrally with the slider body, and a pull handle having one end attached to the bridge and extending from the bridge. Is the main feature.

  In the slide fastener slider according to the present invention, the slider body is preferably made of a synthetic resin.

  Moreover, it is preferable that the slider of this invention has a rotation suppression means which suppresses that the column attachment part of the handle attached to the bridge part rotates around the bridge part. In this case, it is preferable that the rotation inhibiting means is constituted by a tongue piece protruding from the bridging portion. Or the said rotation suppression means may be comprised by adhering the said handle to the said bridge | crosslinking part.

Furthermore, in the slider of the present invention, it is preferable that the handle is configured to be elastically bendable. Alternatively, the handle may be made of a hard synthetic resin.
In addition, the pull is formed by an elongated thin piece including first and second pull main parts disposed in the longitudinal direction of the slider, and a folded part connecting the first and second pull main parts. In the first and second pulling main parts, engaging elements of hook and loop fasteners that can be engaged with and disengaged from each other are disposed on at least a part of the first surfaces that face each other when the pulling part is turned back by the turning part. It is preferable.

  In this case, the first pulling main part is formed longer than the second pulling main part, and the second pulling main part is engaged with the second pulling main part and the second pulling main part. It is preferable that a male engaging element of a hook-and-loop fastener is arranged in the region of the first surface of the first pulling main body portion other than the portion where the pulling main body portion overlaps. In particular, it is preferable that the puller is attached so that the first surface of the first puller main part faces downward when the handle is extended from the bridging portion to the shoulder side of the slider body.

  The slider for a slide fastener according to the present invention has a slider body, a gate-shaped pulling attachment column integrally formed on the upper wing plate of the slider body in a symmetrical manner, and one end of a bridge portion of the pulling attachment column. And a pull handle, the left and right legs standing upright from the upper wing plate spaced apart in the transverse direction of the slider body, and the upper ends of the left and right legs. And a cross-linked part cross-linked between the two.

  In the case of the slider of the present invention having such a configuration, the handle is extended in the longitudinal direction of the slider from the bridge portion by the gate-shaped pulling attachment column arranged in the left-right direction, and the front and back surfaces of the pulling handle are in the sliding direction of the slider. It is arrange | positioned so that it may become sideways with respect to it. Accordingly, the slider handle is easy to pick and the slider can be easily operated, so that the operability is excellent.

  Moreover, the slider of the present invention has one end of the handle attached directly to the handle attachment column without using a conventional metal connecting member. For this reason, even if the handle is in contact with the slider body or in contact with another member, the generation of contact sound can be effectively prevented. In particular, in the present invention, if the slider body is made of a synthetic resin, or the handle is made of a strap, the generation of sound due to contact between the slider body and the handle can be more reliably prevented, and the slider body Even if it contacts with another member, generation | occurrence | production of a contact sound can be prevented effectively.

  In addition, the slider of the present invention includes a rotation restraining means for restraining the column attachment portion of the handle attached to the bridge portion from rotating around the bridge portion. Thereby, the direction of the handle when the slider is not operated can be restricted to a certain direction. For this reason, it is possible to prevent the puller from wobbling and effectively prevent the puller itself from coming into contact with the slider body or other members.

  Furthermore, by restricting the direction of the handle to a certain direction, for example, when the slide fastener is used as a seat cover of a seat, the direction of the handle when the slide fastener is closed can be determined in a predetermined direction. Become. Thereby, when the slider is concealed on the back side of the seat cover, even if the slider receives vibrations of the automobile, the handle does not jump out from the back side of the seat cover, and the handle can be reliably concealed. For this reason, the closed state of the slide fastener can be stably maintained.

  In this case, the rotation restraining means can be easily configured by a tongue piece projecting from the bridging portion, or can be easily constructed by fixing the handle to the bridging portion. For example, when a tongue piece is formed as a rotation restraining means, the slider piece is not operated by projecting the tongue piece in a predetermined direction from the bridging portion, for example, toward the shoulder opening side or the rear opening side in parallel with the upper blade. The direction of the handle at the time can be easily directed to the predetermined direction.

  In the slider of the present invention, the handle is configured to be elastically bendable. As a result, when the slider is slid along the element row, the direction of the handle can be easily turned in the direction in which the slider slides, so that the operation of the slider can be performed smoothly. Further, when the slider has the rotation restraining means, it is possible to reliably turn the puller in a predetermined direction regulated by the rotation restraining means when the handle is released from the finger. . Further, the handle may be made of a hard synthetic resin. Accordingly, it is possible to configure the handle so that it can be easily gripped, and the slider can be easily slid.

  In the present invention, the slider handle is formed of an elongated thin piece having first and second handle main parts arranged in the longitudinal direction of the slider and a folded part connecting them. And the 1st and 2nd pull main part has the engaging element of the hook_and_loop | surface fastener which can mutually engage / disengage to at least one part of each 1st surface. Thereby, the handle can be produced at a low cost and can be easily attached to the handle attachment column of the handle.

  In this case, the first pulling main part of the present invention is formed to be longer than the second pulling main part, and when the first pulling main part and the second pulling main part are engaged with each other A male engaging element of a hook-and-loop fastener is arranged in a region of the first surface of the first pulling main part other than the portion where the second pulling main part overlaps. Thereby, for example, when a slide fastener is used for the seat cover of the seat, when the slider is concealed on the back surface side of the seat cover, the male engagement element arranged on the first surface of the first pulling main portion is formed on the back surface of the seat cover. The slider can be fixed and fixed at a predetermined position. Therefore, since the slider can be prevented from wobbling, the slider can be prevented from coming into contact with the seat frame or the like of the seat, and the generation of the contact sound can be more reliably prevented. Further, even if the slider receives vibrations of the automobile, the element row is not freely slid, and the closed state of the slide fastener can be maintained more stably.

  In particular, in this case, when the handle is extended from the bridge portion of the handle attachment column to the shoulder opening side of the slider body, the first surface of the first handle main body is attached so that it faces downward (upper blade plate side). It is preferable that As a result, when the slider is concealed on the back side of the seat cover, the male engaging element of the first pulling main body can be easily engaged with the back side of the seat cover, and the slider is more securely fixed at a predetermined position. can do.
