Slides and zippers

The present invention relates to a slider formed by assembling and fixing an assembly member to a main member, and more particularly to assembling and fixing the assembly member by inserting the fastener element row of the zipper into the inside of the main member. A slider mounted to the element row while being assembled and a zipper containing the slider.

In the past, the zipper was attached to the opening of an article such as a garment or a bag (a zipper-attached product), and the left and right sprocket rows were engaged by sliding the slider disposed on the zipper along the sprocket row. And separating, thereby opening and closing the opening of the article.

Generally, the slider for the zipper includes a slider body that connects the upper blade and the lower blade with a guide post, and a slider that is rotatably held by the slider body, and is lower than the slider body. A substantially Y-shaped sprocket guide path for guiding the left and right element rows is formed between the plates.

In such a slider for slide fasteners, it is known to form a single slider body by combining two slider members (for example, a first slider member and a second slider member) which are respectively formed. A slider (sometimes referred to as a split slider) is disclosed in, for example, the specification of International Publication No. 2014/006773 (Patent Document 1), in which the size between the upper and lower flaps (the first flap and the second flap) is not easy. A split type slider that produces a deviation.

The split type slide described in Patent Document 1 is formed as a so-called reverse-load type slide fastener in which a fastener element row is disposed on the lower surface (back surface) side of the fastener stringer. Moreover, as shown in FIGS. 14 and 15, the slider 120 includes a slider body 130 and is rotatably held by the slider body 130. A pull tab (not shown).

The slider body 130 includes: an upper blade 131; a lower blade 132; a guide post (not shown) that connects the inlet-side end portions of the upper and lower blades 131 and 132; and a tab mounting post 133 that is disposed on the slider The upper flange side of the flap 131 is vertically disposed on the left and right side edge portions of the upper blade 131, and the lower flange portion 135 is erected along the left and right side edge portions of the lower blade 132.

At the front end of the slider main body 130, the left and right introduction ports are provided with the guide post interposed therebetween, and the engagement opening is provided at the rear end of the slider main body 130. Further, the upper blade 131, the lower blade 132, the pair of right and left upper flange portions 134, and the pair of right and left lower flange portions 135 are formed so as to substantially connect the left and right introduction ports to the meshing port. The sprocket guiding path of the word shape.

The inner wall surface (the sprocket guiding surface) of the sprocket guiding path of the slider main body 130 is composed of the inner surface of the upper blade 131, the inner surface of the lower blade 132, the inner surface of the upper flange portion 134, and the lower flange portion. The inner surface of 135 is formed. Further, a link insertion gap through which the fastener stringer is inserted is formed between the upper flange portion 134 and the lower flange portion 135 at the left and right side edge portions of the slider body 130.

In this case, the height of the lower flange portion 135 from the lower blade 132 is set to be larger than the height of the upper flange portion 134 from the upper blade 131, and the lower flange portion 135 restricts the sprocket guiding path. The position of the inner chain of teeth is held in the element guide path.

On the other hand, the upper flange portion 134 is not in contact with the element row, but by providing the upper flange portion 134, the interval between the link insertion gaps formed between the upper and lower flange portions 134, 135 is reduced to a chain. The tooth row does not exit from the element guide path via the link insertion gap. Further, on the inner surface (the sprocket guide surface) of the lower blade 132, the spacer 136 for guiding the fastener element of the slide fastener is swelled so as to extend from the guide post toward the engagement opening side.

The flap 131 of the patent document 1 is formed of a single member. On the other hand, the lower blade 132 includes: a first lower wing dividing portion 137 having a sprocket guiding surface; and a second lower wing dividing portion The portion 138 is attached to the lower surface of the first lower wing dividing portion 137, and forms a lower blade 132 together with the first lower wing dividing portion 137.

As shown in FIG. 15, the slider main body 130 of the patent document 1 includes a main member (first slider member) 140 and an assembly member (second slider member) 150 assembled to the main member 140. The assembly member 150 is assembled and fixed to the main member 140 to form one slider body 130.

In this case, the main member 140 of the slider body 130 includes the entirety of the upper blade 131, the first lower wing dividing portion 137 of the lower blade 132, the guide post, and the tab mounting post 133, and is formed by injection molding or The entire main member 140 is integrally formed by die casting or the like.

Further, the first lower wing dividing portion 137 includes a first base portion 137a that forms a sprocket guiding surface, and a first embedded portion (embedded concave portion) (not shown) formed at the inlet side end of the first base portion 137a. The second embedded portion (the ridge portion) 137b is disposed on the left and right side edge portions of the first base portion 137a, and the positioning portion 137c protrudes downward from the lower surface of the first base portion 137a.

The assembly member 150 of the slider body 130 includes a second lower wing dividing portion 138 that is fitted to the first lower wing dividing portion 137 of the main member 140, and a lower flange portion 135 that is integrally formed on the second lower wing. The dividing portion 138; and the entire assembly member 150 is integrally formed by injection molding, die casting, or the like.

Further, the second lower wing dividing unit 138 includes a second base portion 138a that is assembled substantially in parallel with respect to the first base portion 137a of the first lower wing dividing portion 137, and a left and right base portion 138b that is disposed at the second base portion. The left and right side edge portions of 138a are the basis of the lower flange portion 135; the extending portion 138c extends forward from the second base portion 138a and is elastically deformable in the vertical direction; the hook-shaped first fitting portion (hook portion) 138d is disposed at an end portion of the extending portion 138c and a groove-shaped second fitting portion (groove portion) 138e disposed at an inner wall portion of the base portion 138b.

In the case of assembling the split type slider main body 130, first, the second fitting portion 138e (groove portion) of the assembly member 150 is fitted from the engagement opening side to the second embedded portion of the main member 140 ( The rib portion 137b further causes the assembly member 150 to face the introduction port side of the main member 140 Sliding relatively. Thereby, the second fitting portion 138e of the assembly member 150 is fitted to the second fitted portion 137b of the main member 140. Thereafter, the assembly member 150 is strongly pressed forward with respect to the main member 140, whereby the hook-shaped first fitting portion 138d of the assembly member 150 is fitted to the first embedded portion of the main member 140. . Thereby, the assembly member 150 is fixed to the main member 140 without being moved, and therefore, the slider main body 130 as shown in FIG. 14 is formed.

According to the slider 120 of Patent Document 1 having the slider main body 130 assembled using the main member 140 and the assembly member 150, it is possible to easily mount the slider main body 130 to, for example, partially separate the left and right element rows. Zip chain.

That is, first, the element row of the left and right separated states is inserted between the first lower wing dividing portion 137 of the main member 140 and the upper blade 131, and the element row is positioned with respect to the main member 140.

Next, the assembly member 150 is fitted and assembled as described above to the main member 140 into which the element rows are inserted. Thereby, the slider main body 130 is attached to the element row of the fastener chain while assembling the slider main body 130, and thus the zipper is formed.

Therefore, by using the split type slider 120 as in Patent Document 1, even after the zipper chain is attached to, for example, a zipper such as a bag, or the stopper or the detachable insert is attached to the end of the zipper chain, After the rear end portion, the slider 120 can also be attached to the chain row of the fastener chain to form a zipper.

Further, when a part of the slider 120 (for example, the tab mounting post 133) is broken in the zipper attached to the zipper-mounted member such as a bag, the sprocket of the slider 120 which is broken by the zipper may be used. After the discharge, the slider 120 of Patent Document 1 is attached to the fastener element row of the zipper. Thereby, the zipper can be easily repaired without changing the entire zipper, and therefore, a large advantage can be obtained economically or environmentally.

Further, in the slider 120 of Patent Document 1, the entirety of the main member 140 is integrally formed as described above. Therefore, the interval between the upper wing plate 131 and the lower wing plate 132 (i.e., the distance between the inner surface of the upper wing plate 131 and the inner surface of the lower wing plate 132) is formed by forming, and therefore, It can be stably sized.

Therefore, it is possible to make the interval between the upper and lower flaps 131 and 132 less likely to cause a deviation (error) in each of the slider bodies 130 to be assembled without being affected by the assembly accuracy when assembling the slider main body 130, and to make the slider main body 130 The size or shape of the sprocket guiding path is stable.

As a result, the posture or the movement of the fastener elements in the fastener guide path when the slider 120 is slid can be stabilized, so that the slidability or operability of the slider 120 can be stably ensured.

Patent Document 1: International Publication No. 2014/006773

In the slide fastener having the slide type 120 of the split type as shown in FIGS. 14 and 15, when the left and right fastener tapes are pulled outward, for example, the fastener elements are applied to the meshing portions of the left and right fastener rows. The transverse pulling force is pulled toward the outer side of the chain width direction. Further, in the slider 120, the element rows in the element guide path contact the left and right lower flange portions 135, and the stress that presses the left and right lower flange portions 135 outward is applied via the element rows.

Here, in the case of, for example, a conventional sliding member which is not a split type, the left and right lower flange portions of the slider main body are integrated with the lower flap, and correspond to the size of the fastener element from the lower flap. The inner surface (the sprocket guide surface) is provided to protrude.

On the other hand, in the split type slider 120 of Patent Document 1, the lower blade 132 is formed by the upper first lower wing dividing portion 137 and the lower second lower wing dividing portion 138, and has a larger height dimension. . Further, since the left and right lower flange portions 135 are provided so as to protrude upward from the lower lower wing dividing portion 137 from the lower side, the height of the lower flange portion 135 itself (ie, the lower portion) The height dimension of the flange portion 135 from the second lower wing dividing portion 138 is higher than the height of the lower flange portion of the conventional slider (ie, the lower flange portion is from the lower wing panel) The height dimension is large.

In the case of the split type 120 including the flange portion 135 having a large height and a long lower length, the lower flange portion 135 is subjected to stress from the element row of the row as compared with the above-described conventional slider. The position (the position of the force point) and the position at which the lower flange portion 135 is coupled to the lower blade 132 (the second lower blade dividing portion 138) and integrated (the position of the fulcrum) are far apart.

Therefore, when the lateral tension is applied to the zipper, for example, when the flange portion 135 is pressed against the outer side via the element row, there is a tendency that the left and right lower flange portions 135 are easily used according to the principle of the lever. The plastic deformation is performed in such a manner as to bend outward, and the strength of the slider 120 with respect to the lateral tensile force is lowered.

Further, when the split type slider 120 of Patent Document 1 is attached to the element row of the fastener chain, as described above, the following operation is performed: the element row is inserted into the first lower wing of the main member 140. After the portion 137 is positioned between the upper blade 131 and the upper blade 131, the assembly member 150 is fitted to the first lower blade dividing portion 137 of the main member 140 to be assembled.

In this case, for example, when the zipper chain is attached to a zipper-attached member such as a bag, when the main member 140 is attached to the sprocket row of the zipper chain, the first lower wing dividing portion 137 of the main member 140 is disposed on the zipper chain. The back of the cloth is hidden on the back side.

Therefore, when the operator performs the assembly work of the assembly member 150 with respect to the main member 140, the first lower wing division portion 137 and the assembly member 150 of the main member 140 cannot be directly visually observed. Therefore, it is difficult to perform work and assembly work time. Excessively longer.

As described above, the slide fastener for a slide fastener of the present invention includes a first flap (for example, a lower flap), a second flap (for example, an upper flap), a guide post, and a chain for the zipper disposed on the first flap. A split type slider body in which a pair of left and right first flange portions are in contact with each other, and the slider main system is formed of a main member and an assembly member which is formed separately from the main member and assembled and fixed to the main member.

Further, the main member has a configuration in which the first flap, the base portion including one of the inner surfaces of the second flap, the guide post, and the pair of left and right first flange portions are integrally formed. The assembly member includes an outer portion including a remaining portion of the inner surface of the second flap and forming a second flap together with the base portion.

In the slider body of the present invention formed by using the main member and the assembly member as described above, the base portion of the main member is formed to include a part of the inner surface of the second flap, and is assembled The outer edge of the member forms a second wing together. Therefore, when the main member is attached to the element row of the fastener chain, the element row can be easily inserted between the first flap of the main member and the base portion. Further, thereafter, the slider body is formed by assembling the assembly member to the main member, and the element row is stably held in the element guide path of the slider body, thereby preventing the element row from being formed, for example, on the slider The chain insertion gaps of the left and right side edges of the main body are withdrawn to the outside. Thereby, the slider body can be easily and stably attached to the element row of the fastener chain.

Further, in the slider body of the present invention formed by the main member and the assembly member, the first flap of the main member and the base portion of the second flap are connected and connected via the guide post, so that the first flap The interval (dimension) between the second and second flaps is not easily affected by the assembly accuracy when assembling the assembled member to the main member, and the interval between the first and second flaps is less likely to occur in each of the assembled sliders. Deviation (error). Thereby, the posture or the movement of the fastener elements in the fastener guiding path during the sliding of the slider is stabilized, and the good sliding property or operability of the slider can be stably ensured.

Further, in the slider body of the present invention, as described above, the first flap is not divided. A single member is formed, and a first flange portion is integrally formed on the right and left side edge portions of the first flap. Therefore, in the present invention, as in the case of the above-described Patent Document 1, the second lower flange portion 135 in which the lower blade 132 is divided is provided with the lower flange portion 135, and the first flange can be used. The height dimension of the portion itself is shortened in accordance with the size of the fastener element, etc. (in other words, it can be set to be substantially the same size as the general slider body which is not a split type).

Therefore, when the slide fastener is formed by using the slider of the present invention, even if a lateral tensile force is applied to the slide fastener, the first flange portion receives the position of the stress point from the element row and the first flange portion and the first wing. The position of the fulcrum in which the plates are joined and integrated is not as far apart as in the case of Patent Document 1, and the distance between the two can be made shorter as in the case of the usual general slider body. Therefore, in the present invention, even if the slider main body is formed in a split type, the first flange portions on the left and right sides are less likely to be plastically deformed as being bent outward, so that the above patent for reducing the strength of the slider relative to the lateral tensile force can be solved. The problem in Document 1.

Further, when the slider of the present invention is used in, for example, a so-called reverse-load type zipper, when the zipper chain is attached to a zipper-mounted member such as a bag, the main member is attached to the sprocket chain of the zipper chain, and the main member is The base portion of the second flap (in this case, the upper flap) is disposed at a position seen on the front side of the fastener fabric of the fastener chain.

Therefore, when the slider is attached to the element row of the fastener chain, the operator can carefully assemble the assembly member to the base portion while carefully observing both the base portion and the assembly member of the second wing in the main member. Since the slider main body is formed, the assembly work of the slider main body can be easily performed in a short time.

In the slider of the present invention as described above, the outer peripheral portion of the assembly member includes a housing space portion that accommodates a portion of the base portion. Thereby, the assembly member can be easily assembled and fixed to the base portion.

In particular, in the present invention, the base portion of the main member includes a base body portion that is disposed at a central portion in the width direction of the second flap and that forms an inner surface of the second flap; The card stopper portion extends from the base body portion in the width direction of the slider, and at least the right and left locking portions of the base portion are fitted into and housed in the housing space portion of the assembly member. Further, the outer peripheral portion of the assembly member includes a pedestal insertion gap in which the base body portion of the base portion is inserted and a space continuous with the accommodating space portion is formed.

Thereby, by sliding the assembly member with respect to the base portion of the main member in the longitudinal direction of the slider, the assembly member can be assembled and fixed to the base easily and stably without being displaced at the position of the assembly member with respect to the main member. Seat. Further, even if the slider is slid along the fastener element row of the slide fastener, the assembly member is less likely to fall off from the autonomous member, and the fixed state of the assembly member with respect to the main member can be stably maintained.

In this case, the outer peripheral portion of the assembly member includes an outer wall portion that is disposed on a surface of the second flap that faces in the vertical direction, and left and right side wall portions that face the first flap from the left and right side edges of the outer wall portion. The left and right side surfaces of the second wing are extended and formed, and the left and right inner wall portions extend from the left and right side wall portions in the width direction of the slider to form an inner surface of the second wing. Further, the accommodating space portion of the outer portion is formed by being surrounded by the outer wall portion, the side wall portion, and the inner wall portion.

As a result, the accommodating space portion that accommodates one of the base body portion of the base portion and the right and left locking portions is stably formed in the outer portion of the assembly member. Therefore, the assembly member is firmly assembled and fixed to the base portion. Therefore, even if the slider is slid, the assembled member can be made less likely to fall off from the autonomous member.

Further, in the invention, the pedestal insertion gap of the assembly member is formed between the left and right inner wall portions of the assembly member, and the inner surface of the second wing formed by the main member and the second wing formed by the assembly member The inner surfaces are formed in the same plane. Thereby, it is possible to prevent the slider obtained by assembling the assembly member to the main member from sliding along the element row of the slide fastener, and the fastener element is caught on the inner surface of the second flap to smoothly slide the slider.

In the slider of the present invention as described above, the width dimension of the base body portion in the base portion of the main member is set to be the same as the width dimension of the guide post, whereby The ground ensures the strength of the base portion.

Here, the term "fixed" means that the assembly member 30 is fixed relative to the main member 20 in an inactive manner (for example, without shaking or shaking) so as not to be easily separated even if a weak external force is applied. The strength is securely installed.

Further, the slider body 10 of the first embodiment assembled by the snap fit in this manner can be separated again from the main member 20 and the assembly member 30. For example, the front end portion of the thinner rod-shaped member is inserted into the recessed portion 25 provided at the end portion of the base portion 21, and further, the front end portion of the assembly member 30 is used in the outer peripheral portion 31 of the assembly member 30 by the front end portion of the rod-shaped member. The rear end portion of the upper wall portion 33 is pressed upward to elastically deform, and the assembly member 30 is slid relatively forward with respect to the main member 20.

Thereby, the engaging projection 24 of the main member 20 is withdrawn from the engaged hole portion 38 of the outer portion 31, and further, the rear end portion of the outer wall portion 33 passes over the engaging projection portion 24, because Thereby, the engagement of the main member 20 and the assembly member 30 can be released. Further, by sliding the assembly member 30 further forward, the base portion 21 of the main member 20 can be detached from the susceptor insertion gap 36 and the accommodating space portion 37 provided in the outer portion 31 of the assembly member 30. Therefore, the main member 20 can be easily separated from the assembly member 30.

The slider main body 10 of the first embodiment, which is assembled using the main member 20 and the assembly member 30 as described above, can be easily attached to, for example, a zipper chain in which one of the left and right element rows 8 is partially separated.

Specifically, first, the left and right element rows 8 are separated from the left and right locking pieces 23 and the lower convex portion of the base portion 21 in the main member 20 in a portion where the left and right element rows 8 are separated in the fastener chain. A gap between the rim portions 16 is inserted between the base portion 21 and the lower blade 12. Further, the relative positioning of the main member 20 and the element row 8 is performed.

At this time, the left and right side edge regions of the inner surface (the element guide surface) of the upper blade 11 and the left and right upper flange portions 15 are provided in the assembly member 30, and therefore, the base portion 21 in the main member 20 A gap of a sufficient size to allow the element rows 8 to be inserted is formed between the left and right locking pieces 23 and the lower flange portion 16.
