The disclosure of PCT International Application No. PCT/JP2019/004350 filed on Feb. 7, 2019, including specification, drawings and claims is incorporated herein by reference in its entirety.
The present invention relates to a concealed-slide-fastener slider in which a body of the slider is concealed on a back surface side in a thickness direction of a fabric, and a pull of the slider appears on a front surface side in the thickness direction of the fabric.
A slide fastener slider is provided with an automatic stop function. There are two types of slide fastener sliders which have the automatic stop function.
One type of the sliders is commonly referred to as an automatic slider. This is because contact and separation of a lock member with respect to a pair of element rows are switched depending on whether or not a pulling operation is performed on a pull. By this switching, movement of a body in a front-rear direction is restricted or the restriction is thus released. More specifically, the automatic slider has two functions. A first function is that the lock member automatically contacts the pair of element rows by releasing hands from the pull. As a result, a front-rear position of the slider is locked, and the slider is difficult to be moved. A second function is that the lock member is separated from the pair of element rows by pulling the pull. As a result, the locking is released, and the slider is easily moved.
A second type of the slide fastener sliders having the automatic stop function is commonly referred to as a semi-automatic slider. This is because the contact and separation of the lock member with respect to the pair of element rows are switched depending on postures of the pull with respect to the body. More specifically, a function of the semi-automatic slider is that the front-rear position of the slider is locked when the pull is in a lying posture with respect to the body, and the locking is released when the pull is in an upright posture with respect to the body, regardless of the pulling operation performed on the pull.
Patent Literature 1 discloses an automatic slider. Since a pair of tape grooves is provided on an upper surface of a body, this slider is a concealed-slide-fastener slider. More details are as follows.
The automatic slider includes: a body; a lock member that is capable of locking a front-rear position of the body and is fixed to front and rear sides of an upper portion of the body; and a pull that is attached by the body and the lock member and is capable of rotating in a front-rear direction and swinging in a left-right direction.
The upper portion of the body includes: left and right flanges; an upper wing plate disposed between the left and right flanges; and a pair of tape grooves formed between the upper wing plate and the left and right flanges. Tapes are passed through the pair of tape grooves. The tapes are bent so as to face lower and upper surfaces of the flanges, and fabrics are fixed to portions facing the upper surface. A pair of fabrics covers left and right side portions of an upper surface of the body. Therefore, the automatic slider of Patent Literature 1 is a concealed-slide-fastener slider.
The body cooperates with the lock member to form a pull attachment portion. A hole, through which a pull connecting ring passes, is provided on an inner side of the pull attachment portion. A lower surface of the hole is lower than the upper surfaces of the flanges. The fabrics are disposed above the flanges via the tapes. When the slider is moved by pulling the pull, the connecting ring is pulled up and suspended above the upper surfaces of the flanges, so that the pair of fabrics is not damaged by the pull (connecting ring).
Patent Literatures 2 and 3 disclose a semi-automatic slider. Since no tape groove is provided on left and right side surfaces of a body, this slider is not a concealed-slide-fastener slider. More details are as follows.
The semi-automatic slider includes: a body; a pull that is capable of rotating about a shaft in a front-rear direction; and a lock member that is fixed to a front portion of an upper portion of the body and is displaced in an up-down direction by a cam portion of the shaft. The body includes tape grooves provided between left and right edge portions of an upper wing plate and a lower wing plate facing each other in the up-down direction, that is, on left and right side surfaces. A pair of tapes are passed through the tape grooves, and a pair of fabrics are fixed to the pair of tapes on left and right sides outer than the tape grooves. As a result, since an entire upper surface of the body is exposed between the pair of fabrics, and the upper surface of the body is not completely concealed by the fabrics, the semi-automatic slider disclosed in Patent Literatures 2 and 3 is not a concealed-slide-fastener slider.

[Patent Literature 2] Japanese Patent No. 6125013
[Patent Literature 3] WO2016/092637
The concealed-slide-fastener slider of the present invention includes a body, a pull, and a lock member. The body guides a pair of tapes that face each other in a left-right direction and a pair of element rows. The pair of element rows is fixed to lower sides of a pair of tape folded portions folded toward lower sides of side edge portions, which face each other, of the pair of tapes. The body includes: a lower wing plate; an upper wing plate that faces a front portion of the lower wing plate; a guide column that joins the upper wing plate and the lower wing plate; a pair of side plates protruding upward from left and right end portions of the lower wing plate; a pair of flanges extending inwardly in the left and right direction from upper end portions of the pair of side plates; and a raised portion raised upward from the upper wing plate.
The pull restricts movement of the body in a front-rear direction by a rearward lying posture with respect to the body and releases the restriction of the movement of the body in the front-rear direction by an upright posture. The pull includes: a shaft, which includes a cam portion engaged with the lock member.
The lock member locks a front-rear position of the body by contacting the pair of element rows, and cooperates with the body to maintain the rearward lying posture and the upright posture of the pull.
The body cooperates with the lock member to form a pull attachment portion. The pull attachment portion includes: a shaft hole that supports the shaft and penetrates in the left-right direction. A lower surface of the shaft hole includes an upper surface of the raised portion and is disposed at a higher position than upper surfaces of the pair of flanges.
A pair of fabric accommodating space portions is formed between the pull in the rearward lying posture and the pair of flanges in an upper-lower direction. The pair of fabric accommodating space portions accommodate a pair of fabrics fixed to upper sides of the pair of tapes and are partitioned by the raised portion in the left-right direction.
It is desirable that upper ranges on the upper surfaces of the pair of flanges are as follows.
That is, only the pair of fabric accommodating space portions are provided in the upper ranges on the upper surfaces of the pair of flanges and are disposed at lower positions than the pull.
It is desirable that the body is as follows.
That is, the body includes: a pair of branch paths of a tape groove between the pair of flanges and the upper wing plate. Only the pair of fabric accommodating space portions is provided in upper ranges on the pair of branch paths is are disposed at a lower position than the pull.
It is desirable that the body, the lock member, and the pull attachment portion are as follows.
That is, the body includes: a front attachment column and a rear attachment column protruding upwardly from the raised portion with an interval therebetween in the front-rear direction. The lock member is bridged between the front attachment column and the rear attachment column. The pull attachment portion is formed by cooperation of the lock member, the front attachment column, the rear attachment column and the raised portion.
More specifically, in addition to the shaft, the pull includes: a pair of rod portions that extend radially about the shaft from two end portions of the shaft; and a grip portion that joins the pair of rod portions on an opposite side of the shaft. Although it does not matter whether the pull includes a protruding portion protruding from the pair of rod portions to an opposite side of the grip with respect to the shaft, it is desirable to minimize inclination of the pull in the left-right direction in the rearward lying posture as follows.
That is, the pull includes: a pair of protruding portions protruding from the pair of rod portions to an opposite side of the grip portion with respect to the shaft. The pair of protruding portions sandwiches the front attachment column when the pull is in the rearward lying posture, and collides with the front attachment column when the pull is inclined in the left-right direction.
Although it does not matter whether the pull can be maintained in a forward lying posture, it is desirable to minimize damage dealt by the pull to the fabric as follows.
That is, the raised portion includes: a step portion that protrudes in a step shape toward the front attachment column in front of the shaft hole. The step portion collides with the pull in a forward lying posture to determine the forward lying posture of the pull.
It does not matter whether the cam portion and the shaft hole are in surface contact with each other when the pull is in the rearward lying posture. However, it is not desirable to maintain the rearward lying posture of the pull by portions other than the cam portion and the shaft hole, since a size of the slider will be increased. Therefore, it is desirable to reduce the size of the slider and minimize portions appearing on a front side with respect to the pair of fabrics as follows.
That is, the cam portion and the shaft hole each include a planar portion. The planar portions are in surface contact when the pull is in the rearward lying posture.
Although the pull may include a portion positioned below the lower surface of the shaft hole when the pull is in the rearward lying posture, it is desirable to maximize dimensions of the pair of fabric accommodating space portions in the up-down direction as follows.
That is, the pull is disposed at a higher position than the lower surface of the shaft hole when the pull is in the rearward lying posture.
The slider disclosed in Patent Literatures 2 and 3 is a semi-automatic slider, and is not used for a concealed-slide-fastener. The slider disclosed in Patent Literature 1, as described above, is an automatic slider, not a semi-automatic slider. Therefore, the present inventor started development of a concealed-slide-fastener slider that maintains the function of the semi-automatic slider (the function of locking the front-rear position of the slider when the pull is in the lying posture with respect to the body, and releasing the locking when the pull is in an upright posture with respect to the body, regardless of the pulling operation performed on the pull).
A case in which a slider is formed simply by combining the body and the lock member of the slider disclosed in Patent Literature 1 and the pull of the slider disclosed in Patent Literature 2 is considered. As a result, although the slider in this case becomes a concealed-slide-fastener slider, the pair of fabrics is easily damaged since the pull is always in contact with the pair of fabrics. That is, in the slider of Patent Literature 1, the lower surface of the hole of the pull attachment portion is lower than the upper surfaces of the flanges. As a result, since the lock member acts to press the lower surface of the shaft against the lower surface of the hole of the pull attachment portion, the pull including the shaft comes close to the pair of flanges and contacts the pair of fabrics.
A concealed-slide-fastener slider of the present invention is made in consideration of the above circumstance, and an object thereof is to minimize damage dealt to the pair of fabrics while maintaining the function of the semi-automatic slider.
As shown in
The pair of fastener stringers 2, 2 includes: a pair of tapes 4, 4 that face each other; and a pair of element rows 5, 5, separately fixed to side edge portions, which face each other, of the pair of tapes 4, 4. In an illustrated example, the element row 5 is formed by bending a monofilament into a coil shape, and elements of one winding of the coil are continuous in a large number.
The concealed-slide-fastener 1 shown in
On the front side of the pair of tape main bodies 4a, 4a, a pair of fabrics 6, 6, which are attachment targets of the concealed-slide-fastener 1, is fixed by sewing threads (not shown) with side edge portions thereof, which face each other, folded toward the back side. More specifically, the pair of fabrics 6, 6 includes: a pair of fabric main bodies 6a, 6a which face each other on the front side; and a pair of fabric folded portions 6b, 6b, which are continuous with side edge portions, which face each other, of the pair of fabric main bodies 6a, 6a and are folded toward the back side.
Hereinafter, directions are defined using three linear directions orthogonal to each other.
A first linear direction is a direction in which the pair of fastener stringers 2, 2 faces each other, in other words, a direction in which the pair of element rows 5, 5 faces each other, and is referred to as a left-right direction. The fastener stringer 2 (tape 4) has a strip shape which is folded so that front and back sides thereof overlap with each other, and a strip width direction thereof is the left-right direction. The left-right direction refers to a left-right direction of
A second linear direction is a longitudinal direction of the pair of fastener stringers 2, 2, in other words, an extension direction of the fastener stringer 2, and is referred to as a front-rear direction.
A front direction is a direction in which the slider 3 is moved when the pair of fastener stringers 2, 2 is closed (when the pair of element rows 5, 5 is engaged with each other). The front direction is a direction facing the back of a direction orthogonal to a paper surface of
A rear direction is a direction in which the slider 3 is moved when the pair of fastener stringers 2 is opened (when the pair of element rows 5, 5 are separated). The rear direction is a direction facing the front of the direction orthogonal to the paper surface of
A third linear direction is a thickness direction of the fastener stringer 2, in other words, a thickness direction of the tape 4, and is referred to as an up-down direction. An upward direction refers to an upward direction of
The slider 3 according to a first embodiment of the present invention is as shown in
The pull 9 includes: a shaft 91; a pair of rod portions 92, 92 that face each other in an extension direction of the shaft 91 and extend from two end portions of the shaft 91 in a radial direction of the shaft 91; a grip portion 93 that joins the pair of rod portions 92, 92 on an opposite side of the shaft 91 and is gripped during operation; and a pair of protruding portions 94, 94 protruding from the pair of rod portions 92, 92 to an opposite side of the grip portion 93 with respect to the shaft 91. As shown in
As shown in
As shown in
The shaft 91 is a rotation center of the pull 9, and extends in the left-right direction. An intermediate portion of the shaft 91 in a longitudinal direction thereof (the left-right direction) serves as a cam portion 91a that engages with the lock member 8. Portions of the shaft 91, located on left and right sides with respect to the cam portion 91a, serve as a pair of shaft main body portions 91b, 91b, which are supported by a shaft hole 32 of a pull attachment portion 31 described below when the pull 9 is rotated. The cam portion 91a has an outer periphery which is not constant with respect to a center line of the shaft 91. As shown in
As shown in
The body 7 is a space portion, which includes: an element path 7a, whose front and rear surfaces are penetrated in the front-rear direction, the pair of element rows 5, 5 passing through the element path 7a; and a tape groove 7b, whose upper surface is penetrated in the front-rear direction so as to communicate with the element path 7a, the pair of tapes 4, 4 passing through the tape groove 7b.
The element path 7a includes: a pair of branch paths 7c, 7c branched toward left and right at a front portion of the body 7; and a merged path 7d in which the pair of branch paths 7c, 7c merge with each other at a rear portion of the body 7.
As shown in
Relationships between the body 7 and the element row 5 are as follows. As shown in
In a plan view, as shown in
The upper wing plate 72 extends in the front-rear direction. As shown in
As shown in
As shown in
As shown in
When the pull 9 is in the forward lying posture, the front attachment column 77, instead of the raised portion 76, is sandwiched by a gap between the pair of rod portions 92, 92 of the pull 9. Therefore, even when the pull 9 in the forward lying posture is inclined in the left-right direction, the pair of rod portions 92, 92 collides with the front attachment column 77 and stops the inclination. As shown in
The pull 9 which is laid forward is placed on the step portion 76a. A front portion of the step portion 76a is the highest as compared with the front attachment column 77. A forward limit position of the rotation range of the pull 9 is determined by contact between the front portion of the step portion 76a and the pull 9 which is laid forward, and the pull 9 is thus in the forward lying posture.
As shown in
The rear attachment column 78 includes a rear accommodating groove 78a that accommodates a rear portion of the lock member 8 at a width central portion of an upper surface thereof. The rear attachment column 78 includes: a rear bottom portion 78b, which forms a bottom surface of the rear accommodating groove 78a; a pair of rear side wall portions 78c, 78c, which form left and right side surfaces of the rear accommodating groove 78a and protrude upward from left and right sides toward the rear bottom portion 78b; and a pair of rear protruding portions 78d, 78d, which protrude inward in the left and right direction so as to approach the pair of rear side wall portions 78c, 78c from upper ends.
The raised portion 76, the front attachment column 77, and the rear attachment column 78 cooperate with each other to form an opening portion (reference numeral omitted) which penetrates in the left-right direction and opens upward. As shown in
The pull attachment portion 31 has an annular shape in a side view, and includes the shaft hole 32 that supports the shaft 91 of the pull 9 inside the annular shape. The shaft hole 32 penetrates in the left-right direction.
As shown in
The lower surface of the shaft hole 32 (the upper surface of the raised portion 76) is a surface on which the shaft 91 (planar portion 91d of the cam portion 91a) of the pull 9 is placed. The planar portion 91d (the lower end 91B of the shaft 91) of the cam portion 91a of the pull 9 overlaps the upper surface (upper end 76T) of the raised portion 76 and is placed thereon when the pull 9 is in the rearward lying posture. An lower end of the pull 9 in the rearward lying posture is the shaft 91. Therefore, the pull 9 in the rearward lying posture is disposed at the higher position than the lower surface of the shaft hole 32. The grip portion 93 of the pull 9 in the rearward lying posture is positioned above a lower surface of the shaft 91 in consideration of operability. Therefore, a lower end 93B of the grip portion 93 is positioned above the planar portion 91d of the cam portion 91a of the pull 9 when the pull 9 is in the rearward lying posture. A virtual line, which is horizontal with the lower end 91B of the planar portion 91d of the cam portion 91a of the pull 9 and is positioned above the lower end 91B of the planar portion 91d of the cam portion 91a of the pull 9, is defined by the lower end 93B of the grip portion 93 when the pull 9 is in the rearward lying posture. A fabric accommodating space portion 33 described below is formed between the virtual line and the upper surfaces of the flanges 75, 75.
The cam portion 91a includes another planar portion 91e in front of the planar portion 91d when the pull 9 is in the rearward lying posture. The planar portion 91e is a plane orthogonal to the front-rear direction, and stabilizes the upright posture of the pull 9 as shown in
In this way, when the pull 9 is in the upright posture and the rearward lying posture, since the shaft hole 32 and the cam portion 91a are in surface contact with each other, the postures are stabilized, and the stabilized postures are maintained by the locking member 8.
As shown in
As shown in
Only the pair of fabric accommodating space portions 33, 33 is provided in upper ranges 75R, 75R on the upper surfaces of the pair of flanges 75, 75 and is disposed at the lower position than the pull 9. The upper ranges 75R, 75R are defined by peripheries of the upper surfaces of the pair of flanges 75, 75. In other words, the upper ranges 75R, 75R only include the pair of fabric accommodating space portions 33, 33 between the upper end 75T of the pair of flanges 75, 75 and the lower end 9B of the pull 9. Therefore, the only tangible object present in the upper ranges 75R, 75R on the upper surfaces of the pair of flanges 75, 75 is the pull 9. For this reason, when the slider 3 is not attached to the fastener stringer 2, the pull 9 and the upper surfaces of the flanges 75, 75 face each other in the upper ranges 75R, 75R when the pull 9 is laid rearward. The raised portion 76 does not exist in the upper ranges 75R, 75R on the upper surfaces of the pair of flanges 75, 75.
As shown in
Since the tape main body 4a is disposed above the flange 75, not only the fabric 6 but also the tape main body 4a is accommodated in the fabric accommodating space portion 33. More specifically, the fabric accommodating space portion 33 accommodates the fabric 6 whose facing side edge portion is folded toward a back side so as to be two-fold, and the tape main body 4a positioned on the upper surface side of the flange 75.
An up-down interval between the pair of fabric accommodating space portions 33, 33 equals to an up-down interval between the pull 9 and the pair of flanges 75, 75, and a minimum distance thereof is preferably set to 2 mm or more. As shown in
In order to maximize the fabric accommodating space portion 33, as shown in
In order to maximize the fabric accommodating space portion 33, as shown in
As described above, the lock member 8 locks the front-rear position of the body 7 with respect to the pair of element rows 5, 5 through contacting the pair of element rows 5, 5, and on the contrary releases the locking of the front-rear position of the body 7 with respect to the pair of element rows 5, 5 through being separated from the pair of element rows 5, 5. The lock member 8 is formed by bending a metal plate into a predetermined shape, which is a so-called plate spring. As shown in
The joining plate 83 has a shape that bulges forward, more specifically, is curved in an arc shape.
The upper plate 81 has a shape whose middle portion in the front-rear direction is positioned above a virtual straight line connecting two ends of the upper plate 81 in the front-rear direction. The upper plate 81 is a curved plate when viewed from a side surface. More specifically, when the upper plate 81 is viewed from a side surface, a front portion and a rear portion of an entire length in the front-rear direction thereof are straight line portions, and the middle portion in the front-rear direction is a smoothly continuous curved portion curved with respect to the front and rear straight portions. The rear straight portion is positioned below a virtual straight line extending rearward from the front straight portion. A tangential direction with respect to front and rear ends of the curved portion coincides with an extending direction of the front and rear straight line portions.
A front portion of the upper plate 81 is accommodated in the front accommodating groove 77a. Left and right sides and a lower side thereof are supported by the pair of front side wall portions 77c, 77c. An upper side thereof is pressed by the pair of front protruding portions 77d, 77d. In order to support the lower side of the upper plate 81, lower portions of the pair of front side wall portions 77c, 77c are formed to be a pair of shelf portions 77e, 77e protruding to approach left and right inner sides with respect to upper portions of the pair of front side wall portions 77c, 77c. The upper plate 81 is placed on the pair of shelf portions 77e, 77e.
The upper side of the upper plate 81 is not only pressed by the pair of front protruding portions 77d, 77d, but also by the pair of front side wall portions 77c, 77c. Therefore, as shown in
The lower plate 82 also has a shape whose middle portion in the front-rear direction is positioned above a virtual straight line connecting two ends of the lower plate 82 in the front-rear direction. The lower plate 82 is a bent plate when viewed from a side surface. More specifically, when the lower plate 82 is viewed from a side surface, a front portion and a rear portion in the front-rear direction thereof are straight line portions, and the front straight line portion and the rear straight line portion are continuous in a bent state. The front straight line portion of the lower plate 82 extends downward toward the front. The rear straight line portion of the lower plate 82 extends downward toward the rear. The lower plate 82 is placed on the cam portion 91a of the shaft 91 of the pull 9, and presses the cam portion 91a from above by a restoring force thereof.
When the pull 9 is in the rearward lying posture, the lower plate 82 presses the cam recessed portion 91c, which is an upper surface of the shaft 91, from above, thereby stabilizing the shaft 91 and the rearward lying posture of the pull 9. When a posture of the pull 9 is between the rearward lying posture and the upright posture, the lower plate 82 presses the cam portion 91a from above by the restoring force and presses the pull 9 into the rearward lying posture. When the pull 9 is in the upright posture and the forward lying posture, the lower plate 82 also presses the cam portion 91a from above by the restoring force and stabilizes the postures.
A tip portion (lower portion) of the pawl plate 85 enters the element path 7a of the body 7. For this reason, the rear attachment column 78, the raised portion 76, and the upper wing plate 72 are formed with pawl hole 7h communicating with the rear accommodating groove 78a and the element path 7a (the merged path 7d) and penetrating in the up-down direction. The pawl plate 85 is accommodated in the pawl hole 7h.
Depending on engagement between the lower plate 82 of the lock member 8 and the cam portion 91a of the shaft 91, an entering amount (length) of the tip portion of the pawl plate 85 entering the element path 7a is changed.
As shown in
As shown in
As shown in
The insertion plate 84 is accommodated in the rear accommodating groove 78a behind the pawl hole 7h.
The slider 3 of the first embodiment described above has the following effects.
The slider 3 restricts or releases the restriction of the movement of the body 7 in the front-rear direction by the upright posture and the rearward lying posture of the pull 9 with respect to the body 7. As shown in
In the slider 3, the pair of fabric accommodating space portions 33, 33 is formed while the lower surface of the shaft hole 32 is positioned above the upper surfaces of the pair of flanges 75, 75 by the raised portions 76, so that the pull 9 is difficult to contact the pair of fabrics 6, 6, and the damage dealt to the pair of fabrics 6, 6 can be reduced as compared with a slider in which the lower surface of the shaft hole is positioned below the upper surfaces of the pair of flanges. The pull 9 does not contact the pair of the fabrics 6, 6, thus the restriction of the movement of the slider 3 in the front-rear direction is prevented from being released. If the pull 9 contacts the pair of fabrics 6, 6, the pull 9 is close to the upright posture, the tip portion of the pawl plate 85 does not protrude into the element path 7a, and the restriction of the movement of the slider 3 in the front-rear direction is released.
In the slider 3, only the pair of fabric accommodating space portions 33, 33 is provided in the upper ranges 75R, 75R on the upper surfaces of the pair of flanges 75, 75 is disposed at the lower position than the pull 9, so that the pull 9 is difficult to contact the pair of fabrics 6, 6, and the damage dealt to the pair of fabrics 6, 6 can be reduced as compared with a slider in which the raised portion 76 protrudes to the upper ranges 75R, 75R on the upper surfaces of the pair of flanges 75, 75, for example. More specifically, in the slider 3, only the pair of fabric accommodating space portions 33, 33 is provided in the upper ranges on the pair of branch paths 7e, 7e is disposed at the lower position than the pull 9, so that the pull 9 is difficult to contact the pair of fabrics 6, 6, and the damage dealt to the pair of fabrics 6, 6 can be reduced as compared with a slider in which the raised portion 76 protrudes to the upper ranges 7R, 7R on the pair of branch paths 7e, 7e, for example.
In the slider 3, the cam portion 91a and the shaft hole 32 each include the planar portions 91d, 32a which are in surface contact with each other when the pull 9 is in the rearward lying posture, so that the size of the slider 3 can be reduced, and portions appearing on the front side with respect to the pair of fabrics 6, 6 can be minimized as compared with a slider in which portions for maintaining the rearward lying posture of the pull are provided in portions other than the cam portion 91a and the shaft hole 32, for example.
In the slider 3, the pull 9 in the rearward lying posture is disposed at the higher position than the lower surface of the shaft hole 32, so that dimensions of the pair of fabric accommodating space portions 33, 33 in the up-down direction can be maximized, and the pull 9 is difficult to contact the pair of fabrics 6, 6, as a result the damage dealt to the pair of fabrics 6, 6 can be further reduced as compared with a slider in which the pull (more specifically the lower surface of the pull) in the rearward lying posture includes a portion positioned below the lower surface of the shaft hole 32. Since the pair of fabric accommodating space portions 33, 33 are widened by the pair of first inclined surfaces 95, 95, the damage dealt to the pair of fabrics 6, 6 can be further reduced.
In the slider 3, when the pull 9 is in the rearward lying posture, the front attachment column 77 is sandwiched by the gap between the pair of protruding portions 94, 94, so that one of the protruding portions 94 collides with the front attachment column 77 when the pull 9 is inclined in the left-right direction, as a result the inclination of the pull 9 in the left-right direction can be minimized, and the rearward lying posture of the pull 9 is stabilized.
As shown in
In the slider 3, when the pull 9 is in the forward lying posture, the pull 9 is placed on the step portion 76a, so that the forward lying posture of the pull 9 is stabilized, and the pair of fabric accommodating space portions 33, 33 can be maintained, so that the damage dealt to the pair of fabrics 6, 6 can be reduced. Since the pair of fabric accommodating space portions 33, 33 are widened by the pair of second inclined surfaces 96, 96, the damage dealt to the pair of fabrics 6, 6 can be further reduced.
In the slider 3, when the pull 9 is in the forward lying posture, a front end portion of the pull 9 is positioned above the lower end of the shaft 91, so that the front end portion of the pull 9 is higher than the pair of fabric accommodating space portions 33, 33, and the pull 9 is easily operated.
Further, in the slider 3, when the pull 9 is in the forward lying posture, the front attachment column 77 is sandwiched by the gap between the pair of rod portions 92, 92 of the pull 9, so that the pair of rod portions 92, 92 collides with the front attachment column 77 when the pull 9 is inclined in the left-right direction, as a result the inclination of the pull 9 in the left-right direction can be minimized, and the forward lying posture of the pull 9 is stabilized.
The present invention is not limited to the above-described embodiment, and modifications can be made without departing from the scope thereof. For example, although in the slider 3 in the above embodiment, the front portion and the rear portion of the lock member 8 are both fixed to the body 7, and the pull 9 is supported only by the pull attachment portion 31, the present invention is not limited thereto, and, for example, the front portion of the lock member may be fixed to the body while the rear portion may be held to be displaceable in the up-down direction, and the pull may be supported by a pair of reinforcement portions, formed on left and right sides with respect to the pull attachment portion, and the pull attachment portion. In this case, the lock member is not bent in a manner that an upper portion and a lower portion thereof face each other, but is bent in the up-down direction from the front portion to the rear portion of the body. In this case, the pull attachment portion is formed by the raised portion and the lock member. In this case, each of the reinforcement portions includes a pair of column portions that is located on a left or right side with respect to the pull attachment portion and protrude upward from the upper wing plate with an interval therebetween. Before attaching the pull to the body, an interval is separated between upper portions of the pair of column portions by a distance larger than a diameter of the shaft, so that the shaft can be dropped and inserted from above the pair of column portions. After the shaft is inserted into the pair of column portions, the upper portions of the pair of column portions are plastically deformed so as to approach each other, so that the interval between the upper portions of the pair of column portions becomes smaller than the diameter of the shaft, thereby preventing the shaft from moving upward with respect to the pair of column portions.
