Description
Technical Field
The present invention relates to a lower stopper for a slide fastener and a slide fastener.
Background
Conventionally, as a lower stopper for a slide fastener, a lower stopper having a width equal to a fastener element width is known, in which movement of a slider is restrained by a restraining surface facing the slider without inserting the entire lower stopper into the slider.
For example, patent document 1 discloses a lower stopper having an upper ridge portion and a lower ridge portion that are raised so that the lower stopper thickness increases toward the stopper surface on the upper surface and the lower surface of the lower stopper. The lower stopper disclosed in patent document 1 has an upper ridge portion and a lower ridge portion, and the thickness of the upper portion and the thickness of the lower portion are made the same, whereby the stopper can be prevented from being entirely thick while securing a stopper force for stopping movement of the slider.

Fig. 4 is a right side view showing a state in which the slider 4 is in contact with the lower stopper 6 in the slide fastener 1 according to the embodiment of the present invention.
As shown in fig. 1, 3 and 4, the slider 4 includes: a main body 40 through which a pair of left and right fastener element rows 3L, 3R are inserted; a pull-tab mounting portion 41 provided on the upper surface of the main body 40; and a pull tab 42 (not shown in fig. 2 (a), (b), 3 and 4) swingably attached to the pull tab attaching portion 41. The slider 4 is formed of, for example, a synthetic resin material, a metal material, or the like.
As shown in fig. 3 and 4, the main body 40 includes: upper wing plate 400; a lower blade 401 disposed opposite to the upper blade 400 in the up-down direction; a connecting column 402 connecting the upper blade 400 and the lower blade 401; upper flange portions 403 provided to stand downward from left and right peripheral edge portions of the upper blade 400; and a lower flange 404 provided to stand upward from the left and right peripheral edge portions of the lower blade 401.

The slider 4 further includes a Y-shaped element passage 43 in a space between the upper blade 400 and the lower blade 401, and the Y-shaped element passage 43 is defined by a connecting post 402, an upper flange 403, and a lower flange 404. That is, the front end side of the slider 4 is divided into a left side and a right side by the connecting post 402 between the upper flange 403 and the lower flange 404, so that a pair of left and right front side open portions 44L, 44R are formed, and a rear side opening 45 is formed between the upper flange 403 and the lower flange 404 on the rear end side of the slider 4, so that a Y-shaped fastener passage 43 is defined as a space for communicating between the pair of left and right front side opening portions 44L, 44R and the rear side opening 45.
The slider 4 moves in the forward direction along the pair of left and right fastener element rows 3L, 3R, thereby causing the fastener element rows 3L, 3R in the separated state to enter the fastener element passage 43 from the pair of left and right front side opening portions 44L, 44R, and causing the fastener element rows 3L, 3R in the separated state to mesh.
On the other hand, the slider 4 moves in the rear direction along the pair of left and right fastener element rows 3L, 3R, thereby causing the engaged fastener element rows 3L, 3R to enter from the rear opening 45 and causing the engaged fastener element rows 3L, 3R to separate. The slider 4 is further moved in the rear direction from the state immediately before the slider is brought into contact with the lower stopper 6 as shown in fig. 2 (a), and is brought into contact with the lower stopper 6 as shown in fig. 2 (b), 3 and 4.

The upper stops 5L, 5R are formed of, for example, a synthetic resin material.
When the slider 4 moves in the forward direction and reaches the distal ends 31L, 31R side of the element rows 3L, 3R, the upper stops 5L, 5R come into contact with the body 40 of the slider 4, thereby preventing the slider 4 from coming off the element rows 3L, 3R.
Fig. 5 shows a bottom stop 6 according to an embodiment of the present invention, (a) is a perspective view showing the bottom stop 6 in a state where the fastener tapes 2L, 2R are sandwiched, and (b) is a perspective view showing the bottom stop 6 of a single body. Fig. 6 shows a lower stopper 6 according to an embodiment of the present invention, in which (a) is a front view, (b) is a left side view, (c) is a right side view, (d) is a top view, and (e) is a bottom view.
As shown in fig. 5 (a), the lower stopper 6 is fixed to the edge portions 20L, 20R of the fastener tapes 2L, 2R in a state of crossing the fastener tapes 2L, 2R by sandwiching the core wires 21L, 21R located on the rear ends 32L, 32R side of the fastener element rows 3L, 3R, thereby connecting the pair of right and left fastener element rows 3L, 3R. The lower stopper 6 is formed of, for example, a synthetic resin material, and has an overall width in the left-right direction equal to the width of the left and right fastener elements, that is, equal to the interval between the left end portion of the left fastener element 30L and the right end portion of the right fastener element 30R.
As shown in fig. 5 and 6, the lower stopper 6 includes, on the rear ends 32L, 32R side of the pair of right and left fastener element rows 3L, 3R: a base 60 that sandwiches core wires 21L, 21R formed at the edges 20L, 20R of the pair of right and left fastener tapes 2L, 2R; a protruding portion 61 disposed on the front side of the base 60; and an inclined portion 62 disposed between the front side of the base portion 60 of the portion where the protruding portion 61 is not disposed and the protruding portion 61.
As shown in fig. 2 (b), 3 and 4, when the slider 4 moves in the backward direction and reaches the rear ends 32L and 32R side of the element rows 3L and 3R, the base 60 abuts against the body 40 of the slider 4, thereby preventing the slider 4 from falling off from the element rows 3L and 3R. At this time, the protruding portion 61 and the inclined portion 62 are not in contact with the body 40 of the slider 4, but are accommodated in the rear opening 45, and the rear opening 45 is a space surrounded by the upper blade 400 and the lower blade 401 arranged in the up-down direction, and the upper flange 403 and the lower flange 404 arranged in the left-right direction.

As a positional relationship in the front-rear direction between the upper substrate facing surface 607 and the lower substrate facing surface 608, the lower substrate facing surface 608 is disposed in the front direction than the upper substrate facing surface 607. When the dimension of the lower stopper 6 in the front-rear direction is set to a length D2 and the distance D3 is set to the distance between the upper substrate facing surface 607 and the lower substrate facing surface 608 in the front-rear direction, the lower substrate facing surface 608 is disposed in the front direction of the upper substrate facing surface 607 so that the ratio of the distance D3 to the length D2 (= (D3/D2) ×100) is, for example, 1 to 20%, and more preferably 1.7 to 8.7%.
The protruding portion 61 is disposed between the upper base portion facing surface 607 and the lower base portion facing surface 608, and includes an upper protruding portion 610 constituting an upper side of the protruding portion 61, and a lower protruding portion 611 constituting a lower side of the protruding portion 61.

The projection 61 includes a projection upper surface 614 which is an upper surface of the upper projection 610, and a projection lower surface 615 which is a lower surface of the lower projection 611.
When the dimension of the rear opening 45 of the slider 4 in the up-down direction is set to the length D1, the thickness T3 of the protruding portion 61 is determined such that the ratio (= (T3/D1) ×100) of the thickness T3 of the protruding portion 61 in the up-down direction with respect to the length D1 is, for example, 60% to 99%. The larger the ratio of the thickness T3 of the protruding portion 61 to the length D1 (= (T3/D1) ×100), the smaller the gap when the protruding portion 61 is accommodated in the rear-side opening 45, that is, the smaller the interval between the protruding portion upper surface 614 and the upper blade lower surface 407 and the interval between the protruding portion lower surface 615 and the lower blade upper surface 408 becomes, so that the rattling when the slider 4 is brought into contact with the lower stopper 6 can be reduced.
The inclined portion 62 is disposed between the upper base portion facing surface 607 and the lower base portion facing surface 608, and includes an upper inclined portion 620 that forms an upper side of the inclined portion 62, and a lower inclined portion 621 that forms a lower side of the inclined portion 62.

According to the slide fastener 1 including the lower stopper 6 according to the embodiment of the present invention, the thickness T2 in the up-down direction of the lower base 601 disposed on the lower surface 22D side of the pair of right and left fastener tapes 2L, 2R is set to be thicker than the thickness T1 in the up-down direction of the upper base 600 disposed on the upper surface 22U side of the pair of right and left fastener tapes 2L, 2R, so that the thickness of the entire base 60 can be increased without raising the upper base 600 higher than the upper surface 22U of the fastener tapes 2L, 2R, and therefore the lower stopper tear strength can be improved without deteriorating the usability and sewing work efficiency of the slide fastener 1.
Further, according to the slide fastener 1 including the lower stopper 6 according to the embodiment of the present invention, since the lower base portion facing surface 608 on the side facing the slider 4 in the lower base portion 601 is disposed in the front direction than the upper base portion facing surface 607 on the side facing the slider 4 in the upper base portion 600, when the slider 4 moves in the rear direction and contacts the base portion 60 by applying the operation force in the rear direction as in the case of operating the tab 42 in the rear direction to the tab 42, the lower base portion facing surface 608 contacts the lower wing plate facing surface 406 before the upper wing plate facing surface 405 contacts. When a large rearward operating force is applied to the tab 42, the slider 4 rotates in a direction in which the upper blade 400 approaches the upper substrate facing surface 607 with the portion where the lower blade facing surface 406 and the lower substrate facing surface 608 come into contact as a rotation axis, and the upper substrate facing surface 607 comes into contact with the upper blade facing surface 405. At this time, even when the interval between the projection upper surface 614 and the upper blade lower surface 407 is narrow, the projection upper surface 614 can be brought into contact with the upper blade lower surface 407.
In this way, in the state where the slider 4 is in contact with the base 60, the operation force applied to the rear direction of the tab 42 acts on the lower stopper 6 via the slider 4, and the operation force applied to the rear direction of the tab 42 acts not in the extending direction of the core wires 21L, 21R (the direction of the force F1 shown in fig. 3) but in the direction inclined to the lower base 601 side (the direction of the force F2 shown in fig. 3) with respect to the extending direction of the core wires 21L, 21R, so that the force acting in the extending direction of the core wires 21L, 21R can be reduced, and the downward displacement of the portion of the lower stopper 6 sandwiching the core wires 21L, 21R can be suppressed. Further, since the force applied to the tab 42 in the rear direction acts on the lower base 601 side having a thicker thickness in the up-down direction than the upper base 660 as in the force F2 shown in fig. 3 when the force acts on the lower stopper 6 through the slider 4, the strength against breakage such as tearing of the lower stopper 6 in the left-right direction due to the rear direction operation force can be enhanced.
Further, according to the slide fastener 1 including the lower stopper 6 according to the embodiment of the present invention, the protruding portion 61 protrudes toward the rear end 32L side of the left fastener element row 3L of the edge portion 20L of the fastener tape 2L provided on the left side in a state where the core thread 21L of the edge portion 20L of the fastener tape 2L formed on the left side is held, and therefore the area of the portion of the lower stopper 6 where the core thread 21L is held is increased by an amount corresponding to the protruding portion 61 protruding toward the rear end 32L side of the left fastener element row 3L, so that the strength when the lower stopper 6 holds the core thread 21L of the fastener tape 2L can be improved.
Further, according to the slide fastener 1 including the lower stopper 6 according to the embodiment of the present invention, since the inclined portion 62 is inclined from the portion where the protrusion 61 clamps the core thread 21L of the edge portion 20L of the fastener tape 2L formed on the left side toward the portion where the core thread 21R of the edge portion 20R of the fastener tape 2R formed on the right side is clamped by the base 60, the inclined portion 62 is disposed at the portion surrounded by the base 60, the protrusion 61, and the rear end 32R of the fastener element row 3R on the right side, the gap (the space S shown in fig. 2 (a)) generated between the inclined portion 62 and the rear end 32R of the fastener element row 3R on the right side can be reduced. Further, since the inclined portion 62 is disposed at a portion to which such a force as to tear the lower stopper 6 in the lateral direction is applied when the fastener tapes 2L, 2R are pulled in the lateral direction, the lower stopper tearing strength can be improved.
(other embodiments)
In the above-described embodiment, as shown in fig. 6, the thickness T2 of the lower base 601 in the up-down direction is uniformly thicker than the thickness T1 of the upper base 600 in the up-down direction throughout the front-back direction, but the thickness of the lower base 601 in the up-down direction may be changed in the front-back direction, or the thickness of the upper base 600 in the up-down direction may be changed in the front-back direction. At this time, the lower base 601 of the portion to which such force as to tear the lower stopper 6 in the left-right direction is applied when the left and right fastener tapes 2L, 2R are stretched in the left-right direction may be thicker in the up-down direction than the other portions.
In the above-described embodiment, as shown in fig. 3, the lower base portion facing surface 608 is disposed in the front direction than the upper base portion facing surface 607 as a front-rear direction arrangement relationship between the upper base portion facing surface 607 and the lower base portion facing surface 608 of the lower stopper 6, and the lower wing plate facing surface 406 is disposed at the same level as the upper wing plate facing surface 405 in the front-rear direction arrangement relationship between the upper wing plate facing surface 405 and the lower wing plate facing surface 406 of the slider 4, but the lower base portion facing surface 608 is not limited to the above-described arrangement relationship as long as the slider 4 moves in the rear direction and contacts the base portion 60 before the upper base portion facing surface 607 contacts the upper wing plate facing surface 405. For example, in the case where the lower blade facing surface 406 is disposed in the front direction of the upper blade facing surface 405, the lower substrate facing surface 608 may be disposed at the same level as the upper substrate facing surface 607 in the front-rear direction.
Although the embodiments of the present invention have been described above, the present invention is not limited to the above embodiments, and can be appropriately modified within the scope not departing from the technical spirit of the present invention.
