Description

Pull tab for slide fastener

Technical Field

The present invention relates to a slider for a slide fastener.

Background

Generally, a zipper provided to a garment or a bag includes: a plurality of fastener elements arranged in a row of 2, which are engaged with each other; and a slider that engages or disengages the pair of element rows while sliding along the element rows on the element. A rod-shaped pull tab is attached to the slider.

Since the pull tab is a relatively small-sized member, it has been proposed to attach a slightly larger operating member to the pull tab in order to improve operability. For example, patent document 1 discloses an extension attached to a slider of a slider that moves up and down along an engagement member in a slide fastener. Further, patent document 2 discloses a pull-cord slider that is attached to a slider in a slide fastener for making the slider easier to handle.

The tab extender of patent document 1 includes a handle and a strap. The handle comprises: the front panel, the back panel of the back side of this front panel, the left and right both sides board of connecting this front panel and back panel, further open-ended top and bottom, and the locating part of inside connection front panel and back panel. The band forms a loop and is arranged in a configuration to receive the stop member therein. Therefore, the handle is not entirely hollow, but a stopper such as a cylinder is disposed at a substantially central portion to connect the front plate and the back plate.

In such a tab-extension, the size of the loop can be freely changed by moving the handle up and down. By enlarging the ring, a person who has not been able to move his or her fingers well, even if his or her hands are not flexible, can easily move the slider up and down by inserting his or her fingers into the ring. In addition, even when the handle is lowered downward and moved toward the end of the belt, the handle can be prevented from falling off the belt by the stopper. However, by disposing the stopper inside the handle, the thickness of the handle is inevitably increased, giving the user a bulky impression.

The string pull tab of patent document 2 has the following structures (i) to (iii).

(I) A pull cord that passes through a through portion provided on a slider side of the slide fastener;

(ii) An end cap having engagement portions on the inner side, the engagement portions being opposed to both ends of the string passing through the through portions, the engagement portions being engaged with the both ends, the two ends being accommodated inside and mounted to the string;

(iii) And 1 or more bridge members including a through hole for passing one side of the string passing between the slider and the end cap and a through hole for passing the other side of the string passing between the slider and the end cap, and formed of rubber or plastic having rubber-like elasticity.

In the string pulling-on tab of patent document 2, by disposing 1 or 2 or more bridge members between the end cap and the slider, it is possible to grasp the string pulling-on tab more easily. However, since the user holds the bridge member to pull the tab, it is difficult to move the tab in a situation where the user is not flexible in his/her hand or is difficult to hold with a glove.

Fig. 5 is an enlarged view of the lower portion of fig. 4. Fig. 6 is a cross-sectional view taken along line VI-VI of fig. 1.

In the present embodiment, the "vertical direction" corresponds to the vertical direction in fig. 1 to 6, and is the longitudinal direction of the slide fastener tab 1. The "upper side" corresponds to the upper side in fig. 1 to 6, and is the side near the slider to which the slide fastener tab 1 is attached. The "lower side" corresponds to the lower side in fig. 1 to 6, and is the side away from the slider to which the slide fastener tab 1 is attached. The "thickness direction" corresponds to the left-right direction in fig. 2 and 4 to 6, and means the thickness direction of the slide fastener tab 1. The "front-back direction" refers to the front-back direction of the tape 20 constituting the slide fastener tab 1. The "left-right direction" corresponds to the left-right direction in fig. 1 and 3, and is a direction orthogonal to the "up-down direction" and the "thickness direction", and is also referred to as the width direction of the slide fastener tab 1 or the tape 20.

As shown in fig. 1 to 6, a slide fastener tab 1 according to the present embodiment includes: a slider mounting portion 10 mounted on a slider not shown; a tape 20 folded in two, and having both end portions 21, 21 of the tape 20 fixed to the slider attachment portion 10 to form a loop portion 23; and a case 30, which is a moving part, mounted to the belt 20 so as to be movable up and down.

The slider mounting portion 10 includes: a slider fixing portion 11 disposed above and fixed to the slider; and a belt fixing portion 13 disposed below and fixed to both end portions 21, 21 of the belt 20. The slider mounting portion 10 is formed of, for example, metal, resin, or the like, and the material thereof is not particularly limited. The slider fixing portion 11 and the strap fixing portion 13 are integrally formed.

As shown in fig. 1 and 3, the slider fixing portion 11 is substantially annular in front view, and a slider, not shown, can be fixed to the central hole 11a of the slider fixing portion 11. The slide fastener forming the slider includes, for example: a plurality of fastener elements arranged in a row of 2, which are engaged with each other; and a slider that engages or disengages the pair of element rows while sliding along the element rows on the elements. The slider mounting portion 10 may be fixed to an existing slider attached to a slider, or the slider mounting portion 10 may be fixed to a body of a slider to which an existing slider has not been attached.

As shown in fig. 2, 4 and 6, the strap fixing portion 13 has a substantially inverted U-shape having an opening at the lower side in a side view. The tape fixing portion 13 has openings on both left and right sides (both sides in the depth direction of the paper in fig. 2, 4, and 6) in addition to the lower side. Through these openings, both end portions 21, 21 of the strap 20 are inserted and fixed inside the strap fixing portion 13.

The strap fixing portion 13 includes: the base 15, the upper part of which is connected to the slider fixing portion 11 at the center in the thickness direction (left-right direction in fig. 2, 4, and 6), is inclined downward from the center toward both sides in the thickness direction; and a pair of leg portions 17, 17 extending downward from both ends in the thickness direction of the base portion 15.

The pair of leg portions 17, 17 face each other with a space therebetween in the thickness direction (left-right direction in fig. 2, 4, and 6), and a space for accommodating both end portions 21, 21 of the belt 20 is formed between the pair of leg portions 17, 17. The pair of leg portions 17, 17 has a plurality of protruding portions 17a, 17a formed on inner surfaces facing each other so as to protrude toward the other leg portion 17. The plurality of protruding portions 17a, 17a in the example of the figure are formed at two positions, i.e., the tip end portion (lower end portion) of the leg portion 17 and the intermediate portion in the up-down direction of the leg portion 17, but the number, shape, and the like of the protruding portions 17a are not particularly limited. The plurality of protruding portions 17a are engaged with protruding portions 21a provided at both end portions 21, 21 of the belt 20 as described later, thereby fixing the belt fixing portion 13 and the belt 20.

Fig. 7 is a perspective view of the belt. Fig. 8 is a side view of the belt. As shown in fig. 7 and 8, the band 20 is an elongated member formed of a resilient member so as to be bendable. The material of the belt 20 is not particularly limited as long as it has elastic force, and a resin material, a rubber material, or the like can be used, and specifically, a thermoplastic resin such as Hytrel (registered trademark) can be used.

The belt 20 includes: a1 st band portion 40 having one end 41 in the longitudinal direction fixed to the slider mounting portion 10; a 2 nd band portion 50 having one end 51 in the longitudinal direction fixed to the slider mounting portion 10; a connecting portion 60 connecting the other end portion 43 of the 1 st belt portion 40 and the other end portion 53 of the 2 nd belt portion 50; and a protruding portion 70 formed on the connecting portion 60 and protruding toward at least one of the front side and the back side of the belt 20. The 1 st band portion 40, the 2 nd band portion 50, the coupling portion 60, and the convex portion 70 are integrally formed. The upper side in fig. 7 and 8 is the back side of the belt 20, and the lower side in fig. 7 and 8 is the front side of the belt 20.

The 1 st belt portion 40 and the 2 nd belt portion 50 of the illustrated example are mirror-symmetrically shaped with respect to the connecting portion 60 connecting them. However, the 1 st belt portion 40 and the 2 nd belt portion 50 may not be mirror-symmetrical shapes.

One end 41 of the 1 st belt portion 40 and one end 51 of the 2 nd belt portion 50 are both end portions 21, 21 of the belt 20. A plurality of protruding portions 41a, 51a protruding toward the front surface side are provided on the front surface (the lower surface in fig. 7 and 8) of the first end portion 41 of the 1 st belt portion 40 and the first end portion 51 of the 2 nd belt portion 50, respectively. The plurality of protruding portions 41a, 51a in the example of the drawing are formed at two positions, i.e., the distal end portion of the one end portion 41, 51 and the intermediate portion of the one end portion 41, 51, but the number, shape, etc. of the protruding portions 41a, 51a are not particularly limited. The protruding portions 41a, 51a can also be referred to as protruding portions 21a, 21a of the both end portions 21 of the belt 20. As shown in fig. 2,4 and 6, the protruding portions 41a and 51a (protruding portions 21a and 21 a) are engaged with the protruding portion 17a of the slider mounting portion 10. On the other hand, the rear surfaces of the one end 41 of the 1 st belt portion 40 and the one end 51 of the 2 nd belt portion 50 are not formed with protruding portions, and are formed in a substantially planar shape, and can be overlapped with each other as shown in fig. 2,4 and 6.

As described above, the connecting portion 60 is a portion connecting the 1 st belt portion 40 and the 2 nd belt portion 50, and is located at the substantially central portion in the longitudinal direction of the belt 20. In this specification, the connecting portion 60 is not a point at which the 1 st belt portion 40 and the 2 nd belt portion 50 are connected, but a portion having a certain distance in the longitudinal direction of the belt 20. The 1 st convex portion 71 and the 2 nd convex portion 73 constituting the convex portion 70 are provided so as to be separated from each other at the coupling portion 60 having a certain distance in the longitudinal direction.

As shown in fig. 2, 4 to 6, the belt 20 is folded in half at the center in the longitudinal direction. That is, the belt 20 is folded back at a portion between the 1 st convex portion 71 and the 2 nd convex portion 73 separated from each other in the connecting portion 60. The folded portion of the connecting portion 60 is referred to as a folded portion 61. The 1 st projection 71 and the 2 nd projection 73 are separated from the folded portion 61 by equal distances on both sides in the longitudinal direction.

The convex portion 70 of the present embodiment includes a 1 st convex portion 71 and a 2 nd convex portion 73 separated from each other in the longitudinal direction of the belt 20. The 1 st protruding portion 71 is formed at the other end 43 of the 1 st band portion 40 constituting the coupling portion 60, and protrudes to at least one of the front side and the back side of the 1 st band portion 40. The 2 nd protrusion 73 is formed at the other end 53 of the 2 nd band 50 constituting the coupling portion 60, and protrudes to at least one of the front side and the back side of the 2 nd band 50.

In the present embodiment, the 1 st convex portion 71 includes a 1 st front convex portion 71a and a 1 st back convex portion 71b protruding to the front side and the back side of the 1 st belt portion 40, and the 2 nd convex portion 73 includes a 2 nd front convex portion 73a and a 2 nd back convex portion 73b protruding to the front side and the back side of the 2 nd belt portion 50. As shown in fig. 2,4 to 6, the 1 st front side convex portion 71a and the 2 nd front side convex portion 73a are formed on the outer peripheral side of the annular portion 23 when the belt 20 is folded in half at the folded portion 61, and the 1 st back side convex portion 71b and the 2 nd back side convex portion 73b are formed on the inner peripheral side of the annular portion 23 when the belt 20 is folded in half.

The length of the 1 st back-side convex portion 71b is substantially equal to the length of the 1 st front-side convex portion 71a in the longitudinal direction and the width direction of the belt 20, and the length of the 2 nd back-side convex portion 73b is substantially equal to the length of the 2 nd front-side convex portion 73 a. On the other hand, as shown in fig. 5, in the front-back direction of the belt 20, the height H2 of the 1 st back-side convex portion 71b is smaller than the height H1 of the 1 st front-side convex portion 71a (H2 < H1), and the height H4 of the 2 nd back-side convex portion 73b is smaller than the height H3 of the 2 nd front-side convex portion 73a (H4 < H3).

Fig. 9 is a perspective view of the case. Fig. 10 is a top view of the case as viewed from the up-down direction. As shown in fig. 9 and 10, the case 30 has a substantially rectangular parallelepiped shape as a whole. The case 30 is formed of, for example, a metal material, a resin material, or the like, but the material thereof is not particularly limited. The case 30 has a through hole 31 at the center thereof, and the through hole 31 has a substantially rectangular cross section and penetrates the case 30 in the vertical direction. Therefore, the case 30 has 4 surfaces around the through hole 31. That is, the case 30 includes: a left-right direction first surface 32 and a left-right direction second surface 33 arranged so as to be separated from each other in the left-right direction, and a thickness direction first surface 34 and a thickness direction second surface 35 arranged so as to be separated from each other in the thickness direction.

The 1 st belt portion 40 and the 2 nd belt portion 50 of the folded-in-half belt 20 are inserted into the through hole 31 in a state of being overlapped in the front-back direction (the paper depth direction in fig. 1 and 3, and the left-right direction in fig. 2, 4 to 6) of the belt 20. Therefore, the through-hole 31 needs to be sized so that the 1 st band 40 and the 2 nd band 50 can be inserted therein. Accordingly, as shown in fig. 1 and 3, the width of the through hole 31 in the lateral direction is set to be larger than the width of the belt 20 (the 1 st belt portion 40 and the 2 nd belt portion 50) in the lateral direction. As shown in fig. 5, the height H1 of the through hole 31 in the front-back direction of the tape 20 is set to be larger than the total height h5+h6 of the height H5 of the 1 st tape portion 40 and the height H6 of the 2 nd tape portion 50 (H1 > h5+h6).

In this way, in the state where the 1 st band portion 40 and the 2 nd band portion 50 are inserted into the through hole 31, the one end portions 41 and 51 provided with the protruding portions 41a and 51a are positioned above the through hole 31, and the connecting portion 60 provided with the 1 st protruding portion 71 and the 2 nd protruding portion 73 is positioned below the through hole 31.

The first end 41 of the 1 st belt 40 and the second end 51 of the 2 nd belt 50 above the through hole 31 are in a state where the planar portions of the back surfaces of the first and second ends 41, 51 overlap each other, and are inserted into the accommodation space between the pair of legs 17, 17 of the belt fixing portion 13. Insertion into the storage space is performed through an opening in the left-right direction (left-right direction in fig. 1 and 3, and paper depth direction in fig. 2,4 to 6) of the tape fixing portion 13. After the one end portions 41, 51 are inserted into the accommodation space, the pair of leg portions 17, 17 are pressed in a direction approaching each other. Thus, the plurality of protruding portions 17a, 17a of the pair of leg portions 17, 17 engage with the protruding portions 41a, 51a provided at the one end portions 41, 51, and the strap fixing portion 13 and the strap 20 are fixed.

As shown in fig. 5, the total height h1+h2+h3+h3+h4 of the height H5 of the 1 st belt portion 40, the height h1+h2 of the 1 st convex portion 71, the height H6 of the 2 nd belt portion 50, and the height h3+h4+h5+h6 of the 2 nd convex portion 73 is greater than the height H1 of the through hole 31 of the case 30 in the front-back direction of the belt 20 (h1+h2+h3+h4+h5+h6 > H1). By setting the height of each portion in this manner, the case 30 can be prevented from falling down as will be described later.

In the slide fastener tab 1 configured as described above, the size of the loop portion 23 of the tape 20 is changed by moving the case 30 up and down, and the slide fastener tab can be used according to the needs of the user.

For example, as shown in fig. 1 and 2, the annular portion 23 of the strap 20 is enlarged in a state in which the case 30 is moved to the upward slider attachment portion 10 side, and thus the inside of the annular portion 23 can be hooked by a finger. Therefore, even a user with inflexible hands or a user wearing gloves or the like can easily pull the pull tab.

Even when the case 30 is moved further upward based on the state shown in fig. 1 and 2, the case 30 does not fall upward due to interference with the tape fixing portion 13 of the slider mounting portion 10.

In fig. 1 and 2, when the case 30 is not pulled downward and is in a no-load state, the case 30 does not naturally move downward. This is because the annular portion 23 of the belt 20 expands in diameter in the thickness direction (left-right direction in fig. 2 and 4 to 6) with its own elastic force downward, and therefore the downward movement of the case 30 is restricted at the portion where the lower end of the through hole 31 contacts the annular portion 23.

When the user holds the case 30 and moves it downward toward the connecting portion 60 on the opposite side of the slider attachment portion 10 based on the state shown in fig. 1 and 2, the annular portion 23 of the strap 20 is elastically reduced in diameter and deformed into the through hole 31 of the case 30 as shown in fig. 3 to 6. As a result, the 1 st belt portion 40 and the 2 nd belt portion 50 constituting the annular portion 23 of the belt 20 move closer to each other, and the annular portion 23 becomes thinner in the thickness direction (left-right direction in fig. 4 to 6) and becomes longer in the up-down direction. This can lengthen the grippable portion of the strap 20. In this case, the zipper pull 1 can be pulled by grasping the tape 20 or the case 30.

In the state shown in fig. 3 to 6, the belt 20 is folded back at the folding portion 61, but since the 1 st convex portion 71 and the 2 nd convex portion 73 are separated from the folding portion 61 by the same distance on both sides in the longitudinal direction, the 1 st convex portion 71 and the 2 nd convex portion 73 are brought close to or in contact with each other. Fig. 5 shows an example in which the 1 st back-side convex portion 71b of the 1 st convex portion 71 and the 2 nd back-side convex portion 73b of the 2 nd convex portion 73 face each other with a slight gap therebetween, and when the case 30 is moved to the lowermost position (the connection portion 60 side), the 1 st back-side convex portion 71b and the 2 nd back-side convex portion 73b may face each other with a gap therebetween or may come into contact with each other.

In this way, since the 1 st convex portion 71 and the 2 nd convex portion 73 are separated from each other in the longitudinal direction of the belt 20, the connecting portion 60 of the belt 20 is easily elastically deformed. Therefore, when the case 30 is moved to the connecting portion 60 side opposite to the slider attaching portion 10, the connecting portion 60 is easily elastically deformed and folded, so that the annular portion 23 of the strap 20 can be thinned to be close to a plate shape. Therefore, the pull tab 1 for slide fastener, which is thin and excellent in appearance, can be realized without giving a large impression of a volume as in the pull tab extension described in patent document 1.

In the tape front-back direction, the height H2 of the 1 st back-side projection 71b is smaller than the height H1 of the 1 st front-side projection 71a (H2 < H1), and the height H4 of the 2 nd back-side projection 73b is smaller than the height H3 of the 2 nd front-side projection 73a (H4 < H3). Therefore, when the case 30 is moved to the maximum extent toward the connecting portion 60 on the opposite side from the slider mounting portion 10, the range of the folded portion 61 of the strap 20 between the 1 st convex portion 71 and the 2 nd convex portion 73 can be narrowed, and thus the plate shape can be approximated, and an elongated impression can be given.

When the case 30 is moved toward the coupling portion 60 on the opposite side of the slider mounting portion 10, the coupling portion 60 is elastically deformed and folded, and the 1 st back-side convex portion 71b of the 1 st convex portion 71 and the 2 nd back-side convex portion 73b of the 2 nd convex portion are brought into contact with each other or face each other with a slight gap therebetween. Therefore, the 1 st projection 71 and the 2 nd projection 73 prevent the tape 20 from entering the through hole 31 of the case 30, and therefore the case 30 can be prevented from falling down.

In particular, in the front-back direction of the belt 20, the total height h1+h2+h3+h4 of the height H5 of the 1 st belt portion 40, the height h1+h2 of the 1 st protruding portion 71, the height H6 of the 2 nd belt portion 50, and the height h3+h4 of the 2 nd protruding portion 73 is set to be larger than the height H1 of the through hole 31 of the case 30 (h1+h2+h3+h4+h5+h6 > H1), and therefore the case 30 can be more reliably prevented from falling downward.

Fig. 5 shows an example in which a vertical gap S exists between the case 30 and the 1 st front side convex portion 71a of the 1 st convex portion 71 and the 2 nd front side convex portion 73a of the 2 nd convex portion 73. Even when the case 30 is moved to the lowest position (the connecting portion 60 side), the elastic force, the shape, and the like of the belt 20 are preferably adjusted to form the vertical gap S as described above. By inserting the user' S nail into the vertical gap S, the case 30 can be moved upward toward the slider attachment portion 10 without depending on the visual sense.

Although not shown, it is preferable that the total height h1+h2+h3+h3+h4 of the height H5 of the 1 st belt portion 40, the height h1+h2 of the 1 st convex portion 71, the height H6 of the 2 nd belt portion 50, and the height h3+h4 of the 2 nd convex portion 73 be equal to the height H2 of the case 30 in the front-back direction of the belt 20 (h1+h2+h3+h4+h5+h6=h2). Thus, the height of the portion of the belt 20 where the 1 st convex portion 71 and the 2 nd convex portion 73 are provided is equal to the height of the case 30, and thus an elongated impression can be given.

(Embodiment 2)

Next, a slide fastener tab 1 according to embodiment 2 will be described. The slide fastener tab 1 of the present embodiment is different from embodiment 1 only in the structure of the convex portion 70, but the other structures are substantially the same as those of embodiment 1, and the same reference numerals are given to the same parts in the drawings, and the description thereof is omitted or simplified.

Fig. 11 is a front view of the slide fastener tab according to embodiment 2, showing a state in which the case is moved to the uppermost position. Fig. 12 is a side view of the slide fastener tab according to embodiment 2, showing a state in which the case is moved to the uppermost position. Fig. 13 is a front view of a slide fastener tab according to embodiment 2, showing a state in which a case is moved to the lowest position. Fig. 14 is a side view of the slide fastener tab according to embodiment 2, showing a state in which the case is moved to the lowest position. Fig. 15 is an enlarged view of the lower portion of fig. 14. Fig. 16 is a cross-sectional view taken along line XVI-XVI of fig. 11. Fig. 17 is an enlarged view of the lower portion of fig. 16. Fig. 18 is a perspective view of the belt.

As shown in fig. 11 to 18, the belt 20 of the present embodiment has a convex portion 70 as in embodiment 1, and the convex portion 70 is formed in the connecting portion 60 so as to protrude toward at least one of the front side and the back side of the belt 20. On the other hand, the convex portion 70 of the present embodiment is different from embodiment 1 in that it does not include the 1 st convex portion 71 and the 2 nd convex portion 73, but has one back-side convex portion 70b.

In embodiment 1, the 1 st convex portion 71 and the 2 nd convex portion 73 are disposed so as to be separated from the folded portion 61 of the coupling portion 60, and thus are configured so as to be easily elastically deformed when the case 30 is moved downward, so that the belt 20 is easily folded at the folded portion 61. In contrast, in the present embodiment, by providing the protrusion 70 (the back-side protrusion 70 b) in the folded portion 61, the belt 20 is not greatly bent in the folded portion 61 when the case 30 is moved downward, and the connecting portion 60 including the folded portion 61 is kept at a height at which it is impossible to enter the through hole 31.

That is, as shown in fig. 17, when the case 30 is moved to the coupling portion 60 side opposite to the slider mounting portion 10, the coupling portion 60 is elastically deformed and folded, but the bending of the coupling portion 60 is limited because the back-side convex portion 70b is provided in the folded portion 61. Thus, the height H7 of the connecting portion 60 can be maintained at a level equal to or higher than the height H1 of the through hole 31 (h7+_h1) in the front-back direction (left-right direction in fig. 17) of the belt 20. This prevents the case 30 from falling downward from the connecting portion 60.

Further, the convex portion 70 may have only the back convex portion 70b protruding to the back side, may have only the front convex portion protruding to the front side, or may have both the back convex portion and the front convex portion, as long as the function of restricting the bending at the folded portion 61 is provided. However, the provision of the backside convex portion as the inner side of the bend can more effectively restrict the bending of the folded portion 61 than the provision of the front side convex portion as the outer side of the bend.

The present invention is not limited to the configuration described in the above embodiment, and can be appropriately modified within a range not departing from the gist of the present invention.

For example, a recess (not shown) that can be fitted to the protrusion 70 of the belt 20 may be provided in the lower portion of the case 30 on the side of the connecting portion 60. In this way, the protruding portion 70 and the recessed portion can be fitted to restrict the movement of the case 30 toward the connecting portion 60, and therefore the case 30 can be more reliably prevented from falling down.

As described above, the following matters are disclosed in the present specification.

(1) A pull-tab for a slide fastener, the pull-tab 1 for a slide fastener comprising:

a slider mounting portion 10 mounted to the slider;

A tape 20 folded in two, and having both end portions fixed to the slider mounting portion 10 to form a loop portion; and

A moving part 30 which is mounted on the belt 20 in a manner capable of moving up and down,

The band 20 includes:

A1 st band portion 40 having one end 41 fixed to the slider mounting portion 10;

a2 nd band portion 50 having one end 51 fixed to the slider mounting portion 10;

a connecting portion 60 that connects the other end portion 43 of the 1 st belt portion 40 and the other end portion 53 of the 2 nd belt portion 50; and

A convex portion 70 formed on the connecting portion 60 and protruding toward at least one of the front side and the back side of the belt 20,

The moving portion 30 has a through hole 31 penetrating the moving portion 30, and is movable up and down on the belt 20 in a state where the 1 st belt portion 40 and the 2 nd belt portion 50 are inserted into the through hole 31.

According to this configuration, since the moving portion 30 is provided so as to be movable up and down on the belt 20 in a state in which the 1 st belt portion 40 and the 2 nd belt portion 50 are inserted into the through hole 31, the size of the annular portion of the belt 20 is changed by moving the moving portion 30, and the belt can be used according to the user's need.

For example, the ring-shaped portion of the strap 20 is maximized in a state where the moving portion 30 is moved toward the slider attaching portion 10 side, and thus the ring-shaped portion can be hooked by a finger. Therefore, even a user with inflexible hands or a user wearing gloves or the like can easily pull the pull tab 1.

Conversely, in a state in which the moving portion 30 is moved toward the connecting portion 60 side opposite to the slider attaching portion 10, the loop portion of the strap 20 becomes smaller, and the portion of the strap 20 that can be gripped can be made longer. In this case, the pull tab 1 can be pulled by holding the strap 20 or the moving portion 30.

Further, a convex portion 70 is formed in the coupling portion 60 on the opposite side of the slider mounting portion 10 in the strap 20.

Therefore, for example, if the portion of the belt 20 where the protruding portion 70 is formed is set to a height at which the through hole 31 of the moving portion 30 cannot be entered, the moving portion 30 can be prevented from falling off from the coupling portion 60 side.

Further, for example, by providing the protruding portion 70 to limit the elastic deformation amount of the coupling portion 60 including the folded portion of the belt 20, the coupling portion 60 is not greatly bent, and the coupling portion 60 maintains a height at which it is impossible to enter the through hole 31 of the moving portion 30. In this case, the moving portion 30 can be prevented from falling off from the coupling portion 60 side.

(2) In the pull-tab 1 for a slide fastener described in (1), the convex portion 70 includes a1 st convex portion 71 and a2 nd convex portion 73 separated from each other,

The 1 st convex portion 71 is formed at the other end portion 43 of the 1 st belt portion 40, protrudes toward at least one of the front side and the back side of the 1 st belt portion 40,

The 2 nd protrusion 73 is formed at the other end 53 of the 2 nd band 50 and protrudes to at least one of the front side and the back side of the 2 nd band 50.

According to this structure, since the 1 st convex portion 71 and the 2 nd convex portion 73 are away from each other, the connecting portion 60 of the belt 20 is easily elastically deformed (easily bent). Therefore, when the moving portion 30 is moved to the connecting portion 60 side opposite to the slider attaching portion 10, the connecting portion 60 is easily elastically deformed and folded, and therefore the annular portion of the strap 20 can be made thin and close to a plate shape. Therefore, the pull tab 1 having a thin and excellent appearance can be realized without giving a large impression of volume as in patent document 1.

(3) In the slide fastener tab 1 described in (2), the 1 st convex portion 71 includes a1 st front convex portion 71a protruding toward the front side of the 1 st tape portion 40 and a1 st back convex portion 71b protruding toward the back side of the 1 st tape portion 40,

The 2 nd protrusion 73 includes a 2 nd front protrusion 73a protruding toward the front side of the 2 nd band 50 and a 2 nd back protrusion 73b protruding toward the back side of the 2 nd band 50.

According to this configuration, when the moving portion 30 is moved to the coupling portion 60 on the opposite side of the slider mounting portion 10 to the maximum, the coupling portion 60 is elastically deformed and folded, and the 1 st back-side convex portion 71b of the 1 st convex portion 71 and the 2 nd back-side convex portion 73b of the 2 nd convex portion 73 are brought into contact with each other or face each other with a slight gap therebetween.

Therefore, the 1 st projection 71 and the 2 nd projection 73 prevent the belt 20 from entering the through hole 31 of the moving portion 30, and therefore the moving portion 30 can be prevented from coming off.

(4) In the slide fastener tab 1 described in (3), the height H2 of the 1 st back-side convex portion 71b is smaller than the height H1 of the 1 st front-side convex portion 71a in the tape front-back direction, and the height H4 of the 2 nd back-side convex portion 73b is smaller than the height H3 of the 2 nd front-side convex portion 73 a.

According to this configuration, when the moving portion 30 is moved to the connecting portion 60 on the opposite side of the slider mounting portion 10 to the maximum, the range of the folded portion of the strap 20 between the 1 st convex portion 71 and the 2 nd convex portion 73 can be narrowed, so that the strap can be made closer to a plate shape, and an elongated impression can be given.

(5) In the slide fastener tab 1 according to any one of (2) to (4), the total height h1+h2+h3+h4+h5+h6 of the 1 st band portion 40, the 1 st protrusion 71, the 2 nd band portion 50, and the 2 nd protrusion 73 in the back-and-forth direction of the band is larger than the height H1 of the through hole 31 of the movable portion 30.

According to this configuration, the 1 st projection 71 and the 2 nd projection 73 can more reliably prevent the belt 20 from entering the through hole 31 of the moving portion 30, and therefore can more reliably prevent the moving portion 30 from coming off.

(6) In the slide fastener tab 1 described in (1), the connecting portion 60 has a folded portion 61, and the folded portion 61 is a portion folded back when the tape 20 is folded back,

The folded portion 61 is provided with the convex portion 70 protruding toward at least one of the front side and the back side of the belt 20.

According to this structure, since the folded portion 61 is thickened by the provision of the convex portion 70, the amount of elastic deformation thereof is reduced, and bending becomes difficult. Thus, the connecting portion 60 having the folded portion 61 can maintain a height at which the through hole 31 of the moving portion 30 cannot be accessed. In this case, the moving portion 30 can be prevented from falling off from the coupling portion 60 side.
