Abstract
Description
- The present invention relates to a slide fastener, and more particularly, to a box pin, a box body and an insert pin of the slide fastener.
- It is known that in a conventional slide fastener, a plurality of fastener elements are arranged along opposing flat element attachment edges of a pair of waterproof fastener tapes each having a waterproof layer which covers the surface of a strip-like core material, a box pin and an insert pin are integrally fixed in an opposing manner to both the front and back surfaces of flat one end of the pair of fastener tapes, the flat one end in which the fastener elements are not present, the slide fastener has a slider through which the fastener elements pass, and an insert pin-fixing member which extends from a portion of the side surface of the insert pin at a side of a tape end to both the front and back surfaces of the fastener tape and is integrally fixed(e.g., refer to Patent Document 1).
- Patent Document 1: Japanese Patent Application Publication No.
2007-097840A - In the slide fastener described in foregoing Patent Document 1, injection molding is performed in order to form the box pin, the box body and the insert pin on the fastener tapes. The fastener tape is pressed by using a tape-pressing member in order to fix the position of the fastener tape during the injection molding. However, since a waterproof layer made of synthetic resin is provided on the surface of the fastener tape and the tape-pressing member for pressing the edges of the fastener tapes in which the box pin, the box body and the insert pin are to be formed is pin-shaped, the pressing force is weak. Thus, the position of the fastener tape may be moved due to the pressure during the injection molding.
- Accordingly, the present invention has been made keeping in mind the above problems, and an object of the present invention is to provide a slide fastener in which the position of a fastener tape can be reliably fixed during injection molding.
- The object of the present invention is achieved by the following configurations.
- (1) A slide fastener including a pair of fastener tapes each having a waterproof layer, a pair of fastener element rows each having a plurality of fastener elements which are respectively arranged along opposing side edges of the pair of fastener tapes, an upper opening slider configured to disengage engagement of the pair of fastener element rows from above, a box pin attached to both front and back surfaces of one end of one of the fastener tapes, the one end where the fastener elements are not present, and an insert pin attached to both front and back surfaces of one end of the other one of the fastener tapes, the one end where the fastener elements are not present, wherein at least one recess which is elongated in a longitudinal direction of the pair of fastener tapes is formed on each of both front and back surfaces of the box pin and both the front and back surfaces of the insert pin.
- (2) The slide fastener according to (1), wherein the at least one recess includes a plurality of recesses, and wherein at least one through-hole is formed on each of the fastener tapes at a position between the plurality of recesses.
- (3) The slide fastener according to (1), further including the upper opening slider configured to disengage the engagement of the pair of fastener element rows from above, and a lower opening slider configured to disengage the engagement of the pair of fastener element rows from below, wherein the recess which is formed on the box pin is configured such that a width dimension thereof increases with distance from the fastener elements in the longitudinal direction of the fastener tapes.
- (4) The slide fastener according to (1), wherein the at least one recess which is formed on the insert pin includes a plurality of recesses, and wherein the front surface of the insert pin is formed with a step at a position between the plurality of recesses.
- According to the slide fastener of the present invention, at least one recess which is elongated in a longitudinal direction of the fastener tapes is formed on each of both the front and back surfaces of the box pin and both the front and back surfaces of the insert pin. Thus, it is possible to form the recesses during the injection molding while increasing the pressing area of the tape-pressing member for pressing the fastener tapes to be greater than the pressing area of a conventional pin-shaped tape-pressing member. Consequently, it is possible to reliably fix the position of the fastener tapes during the injection molding. With this configuration, since the position of the fastener tape during the injection molding is stabilized, it is possible to remarkably increase the attachment strength of the box pin and the insert pin to the fastener tapes. In addition, since the pressing area of the tape-pressing member is large, it is possible to reduce the amount of resin to be used, thereby reducing manufacturing cost.

FIG. 1 to FIG. 12 . - As shown in
FIG. 1 andFIG. 2 , theslide fastener 10 of this embodiment includes a pair of left andright fastener tapes 20, a pair of left and rightfastener element rows 30, anupper opening slider 40A, alower opening slider 40B, abox pin 50, aninsert pin 60 andtop end stops 70. Each of the pair of left andright fastener tapes 20 haswaterproof layers 21 on front and back surfaces of a woven or knitted tape material. Thewaterproof layers 21 are made of a synthetic resin thermoplastic elastomer (e.g. polyester elastomer, polyurethane elastomer, or the like). Each of the pair of left and rightfastener element rows 30 has a plurality offastener elements 31 which are respectively arranged along opposingtape side edges 20a of the pair of left andright fastener tapes 20. Each of the upper andlower opening sliders 40A, 40Bpasses the pair of left and rightfastener element rows 30 therethrough, and engage and disengage the pair of left and rightfastener element rows 30 with and from each other. Thebox pin 50 is attached to both the front and back surfaces of the lower end (one end) of the right (one)fastener tape 20, where thefastener elements 31 are not present. Theinsert pin 60 is attached to both the front and back surfaces of the lower end (one end) of the left (the other)fastener tape 20, where thefastener elements 31 are not present. Thetop end stops 70 are respectively attached to upper ends of the pair of left andright fastener tapes 20, where thefastener elements 31 are not present. - The
waterproof layer 21 is a layer that does not allow fluid such as water to pass through. Here, the fluid is not limited to water but may be any types of liquid (fluid), for example, oil or gas. In addition, the tape material may be non-woven fabric rather than the woven or knitted material. In addition, thetop end stops 70 may be provided on the pair of left andright fastener tapes 20, or notop end stops 70 may be provided. In this case, when attaching theslide fastener 10 to an object such as a garment, theslide fastener 10 is attached such that theupper opening slider 40A is not dislodged. - Each of the pair of left and right
fastener element rows 30 is composed of a plurality offastener elements 31. Eachfastener element 31 is formed on thetape side edge 20a of thefastener tape 20 by injection molding using synthetic resin, such as polyamide, polyacetal, polypropylene, polybutyleneterephthalate, or the like. - The
upper opening slider 40A and thelower opening slider 40B are sliders with automatic stop function, and are provided such that rear mouth sides thereof face each other. When theupper opening slider 40A is moved upwards (in a direction away from thelower opening slider 40B) by pulling a pull-tab 41, the left and rightfastener element rows 30 which are in the disengaged state are engaged with each other. When theupper opening slider 40A is moved downwards (in a direction approaching thelower opening slider 40B), the left and rightfastener element rows 30 which are in the engaged state are disengaged from each other. In addition, when thelower opening slider 40B is moved upwards (in a direction approaching theupper opening slider 40A) by pulling the pull-tab 41, the left and rightfastener element rows 30 which are in the engaged state are disengaged from each other. When thelower opening slider 40B is moved downwards (in a direction away from theupper opening slider 40A), the pair of left and rightfastener element rows 30 which are in the disengaged state are engaged with each other. - Each of the
box pin 50 and theinsert pin 60 is formed on the respective lower ends of the tape side edges 20a of thefastener tapes 20, as shown inFIG. 2 to FIG. 7 , by injecting molding using synthetic resin, such as polyamide, polyacetal, polypropylene, polybutyleneterephthalate, or the like. - The
box pin 50 is a member that is substantially rectangular column-shaped. Thebox pin 50 is configured such that at the lower end thereof the width dimension thereof increases with distance from thefastener elements 31 in the longitudinal direction of the fastener tapes 20 (in the downward direction). In addition, astopper 51 is formed on a side surface of the upper end of thebox pin 50, the side surface that faces theinsert pin 60. Thestopper 51 is configured to be engaged with anengagement recess 62 of theinsert pin 60, which will be described later, and as shown inFIG. 8 , determines an inserting position of theinsert pin 60 into thelower opening slider 40B. - The
insert pin 60 is a member that is substantially rectangular column-shaped. Theinsert pin 60 has anengagement section 61 on a side surface of the upper end thereof, the side surface that faces thebox pin 50. As shown inFIG. 8 , theengagement section 61 is configured to be engaged with thelowermost fastener element 31 of thefastener element row 30 at a side of thebox pin 50. In addition, theengagement recess 62 configured to be engaged with thestopper 51 of thebox pin 50 is formed on a side surface of theinsert pin 60 below theengagement section 61. In addition, as shown inFIG. 7 andFIG. 8 , astep 63 is formed on the front surface of theinsert pin 60 at substantially the central section thereof. Astop claw 44 of thelower opening slider 40B is configured to be engaged with thestep 63. As shown inFIG. 7 , the thickness of the lower side of thestep 63 in the front-back direction is smaller than that of the upper side of thestep 63. In addition, as shown inFIG. 2 to FIG. 4 , an insert pin-fixingmember 64 is formed on a side surface of the lower end of theinsert pin 60, the side surface that is directed away from thebox pin 50. The insert pin-fixingmember 64 extends outwardly in the width direction (in a direction away from the box pin 50) from the side surface of theinsert pin 60, and is formed on both the front and back sides of thefastener tape 20. In addition, the thickness of the insert pin-fixingmember 64 is set to be smaller than that of theinsert pin 60. - In the above-described embodiment, the
insert pin 60 is a member that is to be inserted from the left side of a guide post of theupper opening slider 40A, and thebox pin 50 is a member that holds theupper opening slider 40A and thelower opening slider 40B. Therefore, theinsert pin 60 and thebox pin 50 are accommodated inside theupper opening slider 40A and thelower opening slider 40B, and the dimension thereof in the front-back direction is formed to be greater than that of thefastener tape 20. Thus, theinsert pin 60 and thebox pin 50 abuts flanges of the slider when theinsert pin 60 and thebox pin 50 are accommodated inside the slider and this prevents theinsert pin 60 and thebox pin 50 from escaping in the width direction. - Here, describing the
slide fastener 10, in a state where theupper opening slider 40A and thelower opening slider 40B are moved to the lower end (to the box pin 50), theinsert pin 60 is inserted into theupper opening slider 40A until theinsert pin 60 is engaged with thestopper 51 of thebox pin 50. Afterwards, theupper opening slider 40A is moved upwards, so that the left and rightfastener element rows 30 are engaged with each other, thereby closing theslide fastener 10. When thelower opening slider 40B is moved upwards in this state, the left and rightfastener element rows 30 are separated from a side of thebox pin 50 and theinsert pin 60. - In this embodiment, as shown in
FIG. 2 to FIG. 7 , both the front and back surfaces of thebox pin 50 are formed withrecesses recess fastener tape 20 from the front or back surface of thebox pin 50. Both the front and back surfaces of theinsert pin 60 is formed withrecesses recess 11 reaches thefastener tape 20 from the front or back surface of theinsert pin 60. Therecesses members 81 of amold 80 shown inFIG. 9 andFIG. 10 (a mold at a side of theinsert pin 60 is not shown) press thefastener tapes 20 when forming thebox pin 50 and theinsert pin 60 by the injection molding. Consequently, therecesses reference numeral 82 inFIG. 9 andFIG. 10 denotes a cavity with which molten resin is filled in order to form thebox pin 50 by injection molding.Reference numeral 83 denotes an element-accommodating space in which thefastener elements 31 are to be accommodated during the injection molding. Since the tape-pressingmembers 81 press thefastener tapes 20 along thetape side edges 20a, the tape side edges 20a are not waved in the front-back direction. - In addition, the
recess 11 of thebox pin 50 at a side of thefastener element row 30 and therecesses 11 of theinsert pin 60 are formed into an elongated circular shape along the longitudinal direction of thefastener tapes 20. Therecess 12 of thebox pin 50 at a lower side (below the above recess 11) have a substantially trapezoidal shape along the longitudinal direction such that the width dimension thereof increases with distance from thefastener elements 31 in the longitudinal direction of the fastener tapes 20 (in the downward direction). In addition, as shown inFIG. 3 andFIG. 4 , two trapezoidal-shapedrecesses 13 and three circular-shapedrecesses 14 are formed on each of both the front and back surfaces of the insert pin-fixingmember 64. In addition, as shown inFIG. 1 , anrecess 15 which is formed into elongated circular shape along the longitudinal direction of the fastener tapes is formed on each of both the front and back surfaces of the top end stops 70. - In addition, as shown in
FIG. 3 to FIG. 7 , in theright fastener tape 20, fixing through-holes 22 are formed at positions above therecess 11 of thebox pin 50, between therecesses recess 12. With this configuration, thebox pin 50 on the front surface of thefastener tape 20 and thebox pin 50 on the back surface of thefastener tape 20 are connected in the front-back direction via connectingsections 22a which are formed in three fixing through-holes 22. In the meantime, the fixing through-holes 22 penetrate through thefastener tape 20 in the front-back direction. - In addition, in the
left fastener tape 20, the fixing through-holes 22 are formed at positions above therecess 11, between therecesses recess 11 of theinsert pin 60. With this configuration, theinsert pin 60 on the front surface of thefastener tape 20 and theinsert pin 60 on the back surface of thefastener tape 20 are connected in the front-back direction via connectingsections 22a which are formed in three fixing through-holes 22. In addition, a fixing through-hole 23 which is the same as the fixing through-holes 22 is also formed at a position betweenupper recesses member 64. - In addition, fixing through-
holes 24 are formed at forming positions ofrespective fastener elements 31 on the pair of left andright fastener tapes 20. With this configuration, thefastener elements 31 on the front surface of thefastener tape 20 and thefastener elements 31 on the back surface of thefastener tape 20 are connected in the front-back direction via connectingsections 24a which are formed in the fixing through-holes 24. - As described above, according to the
slide fastener 10 of this embodiment, therecesses fastener tapes 20 are formed on both the front and back surfaces of thebox pin 50 and both the front and back surfaces of theinsert pin 60. Thus, it is possible to form therecesses members 81 for pressing thefastener tapes 20 to be greater than the pressing area of a conventional pin-shaped tape-pressing member. It is therefore possible to reliably fix the position of thefastener tapes 20 in the width direction and in the front-back direction during the injection molding. With this configuration, since the position of thefastener tapes 20 during the injection molding is stabilized when forming thebox pin 50 and theinsert pin 60 on thefastener tapes 20 having thewaterproof layer 21, it is therefore possible to remarkably increase the attachment strength of thebox pin 50 and theinsert pin 60 to thefastener tapes 20. In addition, since the pressing area of the tape-pressingmembers 81 is large, it is possible to reduce the amount of resin to be used, thereby reducing manufacturing cost. Furthermore, the longitudinal dimension of each of therecesses - In addition, according to the
slide fastener 10 of this embodiment, the fixing through-holes 22 are formed on thefastener tapes 20 at positions between therecesses 11, 12 (11, 11), and thebox pin 50 and theinsert pin 60 are connected in the front-back direction via the fixing through-holes 22 in a state where thefastener tapes 20 are reliably pressed. Thus, it is possible to further increase the attachment strength of thebox pin 50 and theinsert pin 60 to thefastener tapes 20. - In addition, according to the
slide fastener 10 of this embodiment, therecess 12 which is formed on thebox pin 50 is configured such that the width dimension thereof increases with distance from thefastener elements 31 in the longitudinal direction of thefastener tapes 20. Thus, it is therefore possible to further increase the pressing area of the tape-pressingmembers 81 at the lower end side of thefastener tape 20, thereby further reliably fixing the position of thefastener tape 20 during the injection molding. In addition, it is possible to further decrease the amount of resin to be used, thereby further reducing the manufacturing cost. - In addition, in order to maintain the strength of the
box pin 50 and theinsert pin 60, it is preferable to form therecesses 11 of theinsert pin 60 so as to be positioned below theengagement section 61, as shown inFIG. 8 . Consequently, in a state where theengagement section 61 is engaged with thelowermost fastener element 31 at a side of thebox pin 50, the strength can sufficiently stand against lateral pulling force. Further, thelower recess 11 of therecesses 11 of theinsert pin 60 is positioned at a left side relative to an abutting position between thestep 63 and thestop claw 44 in a state where thelower opening slider 40B abuts against thestep 63. This consequently prevents thestop claw 44 of thelower opening slider 40B from being clogged in therecess 11. In addition, therecesses 11 of thebox pin 50 are formed so as to be positioned below the surface in which thestopper 51 is engaged with theengagement recess 62 of theinsert pin 60. Thus, the attachment strength can be maintained. - In addition, according to the
slide fastener 10 of this embodiment, a plurality ofrecesses insert pin 60 and thestep 63 is formed at a position between therecesses insert pin 60. It is therefore possible to form thestep 63 at a suitable position of theinsert pin 60 on which therecesses - As a modified embodiment of this embodiment, as shown in
FIG. 11 andFIG. 12 , thewaterproof layer 21 may be provided only on the front surface of thefastener tapes 20. - In sequence, a second embodiment of the slide fastener according to the present invention is described with reference to
FIG. 13 and FIG. 14 . In the meantime, as for the same or equivalent portions as the first embodiment, the same reference numerals will be used in the drawings and descriptions of some features will be omitted or simplified. - As shown in
FIG. 13 and FIG. 14 , thefastener 10 of this embodiment uses anopening unit 90 in place of an inverse opening unit which includes thebox pin 50, theinsert pin 60 and thelower opening slider 40B in the first embodiment. Therefore, although not shown, theslide fastener 10 of this embodiment has only theupper opening slider 40A. - The
opening unit 90 includes thebox pin 50, abox body 55 and theinsert pin 60. Thebox pin 50 and thebox body 55 are formed on the lower end of thetape side edge 20a of theright fastener tape 20. Theinsert pin 60 is formed on the lower end of thetape side edge 20a of theleft fastener tape 20, and can be inserted into thebox body 55. - The
box body 55 is integrally molded on the lower section of thebox pin 50, and an insert pin-receivingspace 56 is formed in the left half section of thebox body 55. The insert pin-receivingspace 56 is opened in the up-down direction such that theinsert pin 60 is inserted thereinto. In addition, aslit 57a is formed on asidewall section 57 at a side of theinsert pin 60, the sidewall section defining the insert pin-receivingspace 56, such that the insert pin-fixingmember 64 of theinsert pin 60 is to be inserted thereinto. In addition, rectangular-shapedrecesses 16 are formed on both the front and back surfaces of the right half section of thebox body 55, along the longitudinal direction of thefastener tapes 20. Eachrecess 16 has a depth such that therecess 16 reaches thefastener tape 20. Although thebox pin 50 and thebox body 55 are integrally molded in this embodiment, this is not limited. Thebox pin 50 and thebox body 55 may be molded as separate pieces, and thebox body 55 may be engaged with and fixed to the lower section of thebox pin 50. - As described above, according to the
slide fastener 10 of this embodiment, therecesses fastener tapes 20 are formed on both the front and back surfaces of thebox pin 50, thebox body 55 and theinsert pin 60. Thus, it is possible to form therecesses fastener tapes 20 to be greater than the pressing area of a conventional pin-shaped tape-pressing member. Consequently, it is possible to reliably fix the position of thefastener tapes 20 in the width direction and in the front-back direction during the injection molding. With this configuration, since the position of thefastener tapes 20 during the injection molding is stabilized when forming thebox pin 50 and theinsert pin 60 on thefastener tapes 20 having thewaterproof layer 21, it is therefore possible to remarkably increase the attachment strength of thebox pin 50, thebox body 55 and theinsert pin 60 to thefastener tapes 20. In addition, since the pressing area of the tape-pressing members is large, it is possible to reduce the amount of resin to be used, thereby reducing manufacturing cost.
The other configurations, operations and advantageous effects are the same as those of the above-described first embodiment. - In the meantime, the present invention is not limited to those that were illustrated in the foregoing embodiments but can be suitably changed without departing from the concept of the invention.
In an example, the fastener element row can be prepared by other methods than the injection molding. Specifically, coil-type fastener elements which are formed by molding a mono-filament into the shape of a coil may be arranged on thetape side edge 20a. -
