Description

Slider and slide fastener

The present invention relates to a slider formed by assembling and fixing an assembling member to a main member, and in particular, assembling and fixing an assembling member in a state where an element row of a slide fastener is inserted inside the main member. The present invention relates to a slider that can be attached to an element row at the same time as assembly and a slide fastener having the slider.

Conventionally, a slide fastener is used by being attached to an opening of an article (a fastener-attached product) such as clothing or a bag, and by sliding a slider arranged on the slide fastener along an element row, Can be engaged / separated to open / close the opening of the article.

In general, a slider used in a slide fastener has a slider body in which an upper blade and a lower blade are connected by a guide column, and a handle that is rotatably held with respect to the slider body. Between the upper and lower blades, a substantially Y-shaped element guide path for guiding the left and right element rows is formed.

Among such slide fastener sliders, a split type in which one slider body is formed by mutually connecting two slider members (for example, a first slider member and a second slider member) separately formed. A slider (sometimes called a divided slider) is known. For example, International Publication No. 2014/006773 pamphlet (Patent Document 1) discloses a dimension between upper and lower blades (first blade and second blade). There is disclosed a division type slider that is less likely to vary.

The split type slider described in Patent Document 1 is formed for a so-called reverse use type slide fastener in which an element row is arranged on the lower surface (back surface) side of the fastener tape. As shown in FIGS. 14 and 15, the slider 120 includes a slider body 130 and a handle (not shown) that is rotatably held by the slider body 130.

The slider body 130 includes an upper wing plate 131, a lower wing plate 132, guide pillars (not shown) that connect the upper and

lower wing plates

131 and 132, and a handle disposed on the upper surface side of the upper wing plate 131. The mounting post 133 includes an upper flange portion 134 that is suspended from the left and right edge portions of the upper wing plate 131, and a lower flange portion 135 that is erected along the left and right edge portions of the lower wing plate 132.

Left and right shoulder openings are provided at the front end portion of the slider body 130 with a guide column interposed therebetween, and a rear opening is provided at the rear end portion of the slider body 130. Also, a substantially Y-shaped element that connects the left and right shoulder openings and the rear opening so as to be surrounded by the upper wing board 131, the lower wing board 132, the pair of left and right upper flange parts 134, and the pair of left and right lower flange parts 135. A guideway is formed.

The inner wall surface (element guide surface) of the element guide path of the slider body 130 is formed by the inner surface of the upper wing plate 131, the inner surface of the lower wing plate 132, the inner surface of the upper flange portion 134, and the inner surface of the lower flange portion 135. . Further, a tape insertion gap for inserting a fastener tape of a slide fastener 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 dimension of the lower flange portion 135 from the lower wing plate 132 is set to be larger than the height dimension of the upper flange portion 134 from the upper wing plate 131, and the lower flange portion 135 serves as the element guide path. The position of the element row inside is restricted, and the element row is held in the element guide path.

On the other hand, although the upper flange portion 134 does not contact the element row, by providing the upper flange portion 134, the interval between the tape insertion gaps formed between the upper and

lower flange portions

134 and 135 is reduced. It is narrowed to a size that does not pull out from the element guide path. Further, on the inner surface (element guide surface) of the lower wing plate 132, a partition portion 136 for guiding the fastener element of the slide fastener is raised and arranged so as to extend from the guide column toward the rear opening side. Yes.

The upper blade 131 of Patent Document 1 is formed of a single member. On the other hand, the lower wing plate 132 is attached to the first lower wing division portion 137 having an element guide surface and the lower surface of the first lower wing division portion 137, and the lower wing plate 132 is moved together with the first lower wing division portion 137. And a second lower blade split portion 138 to be formed.

Such a slider body 130 of 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, as shown in FIG. The slider body 130 is formed by assembling and fixing the assembly member 150 to the main member 140.

In this case, the main member 140 of the slider body 130 includes the entire upper blade 131, the first lower blade split portion 137 of the lower blade 132, a guide column, and a pull attachment column 133, and the injection The entire main member 140 is integrally formed by molding or die casting.

The first lower blade split portion 137 includes a first base portion 137a that forms an element guide surface, and a concave first fitting portion (insertion recess portion) that is formed on the shoulder-side end of the first base portion 137a. And a second fitting portion (protruding portion) 137b disposed on the left and right side edge portions of the first base portion 137a, and a positioning portion 137c protruding downward from the lower surface of the first base portion 137a.

The assembly member 150 of the slider body 130 includes a second lower blade split portion 138 that fits into the first lower blade split portion 137 of the main member 140, and a lower flange that is integrally formed with the second lower blade split portion 138. The entire assembly member 150 is integrally formed by injection molding or die casting.

The second lower blade split portion 138 is disposed on the second base portion 138a assembled substantially parallel to the first base portion 137a of the first lower blade split portion 137 and the left and right side line portions of the second base portion 138a. Left and right base portions 138b that serve as the base of the flange portion 135, an extension portion 138c that extends forward from the second base portion 138a and is elastically deformable in the vertical direction, and a hook-like shape that is disposed at the distal end portion of the extension portion 138c The first fitting portion (groove portion) 138d and the concave groove-like second fitting portion (concave groove portion) 138e disposed on the inner wall portion of the base portion 138b.

When assembling such a split type slider body 130, first, the second fitting portion 138e (concave groove portion) of the assembly member 150 is rearwardly connected to the second fitting portion (projection portion) 137b of the main member 140. It is inserted from the mouth side, and the assembly member 150 is further slid relative to the shoulder side of the main member 140. Accordingly, the second fitting portion 138e of the assembly member 150 is fitted to the second fitting portion 137b of the main member 140. Thereafter, by strongly pressing the assembly member 150 forward with respect to the main member 140, the hook-shaped first fitting portion 138d of the assembly member 150 is fitted to the first fitting portion of the main member 140. . As a result, the assembly member 150 is fixedly fixed to the main member 140, so that the slider body 130 as shown in FIG. 14 is formed.

Thus, according to the slider 120 of Patent Document 1 including the slider body 130 assembled using the main member 140 and the assembly member 150, for example, with respect to a fastener chain in which a part of the left and right element rows is separated, It is possible to easily attach the slider body 130 at the same time as assembling.

That is, first, the element row is positioned with respect to the main member 140 while inserting the separated left and right element rows between the first lower blade split portion 137 and the upper blade plate 131 of the main member 140.

Next, the assembly member 150 is fitted and assembled to the main member 140 in which the element row is inserted as described above. Thus, since the slider body 130 is assembled and the slider body 130 is attached to the element row of the fastener chain, a slide fastener is formed.

Therefore, by using the split type slider 120 as in Patent Document 1, for example, after attaching a fastener chain to a fastener-attached product such as a bag, or at the front end and the rear end of the fastener chain Even after the insertion tool is attached, the slide fastener can be formed by attaching the slider 120 to the element row of the fastener chain.

Further, in a slide fastener that is already attached to a fastener attaching member such as a bag, when a part of the slider 120 (for example, the pulling attachment column 133) is damaged, the damaged slider 120 is removed from the slide fastener. After being removed from the element row, the slider 120 of Patent Document 1 can be attached to the element row of the slide fastener. Thereby, since it becomes possible to repair a slide fastener easily, without replacing | exchanging all the slide fasteners, a big merit can be acquired economically and environmentally.

In addition, in the slider 120 of Patent Document 1, the entire main member 140 is integrally formed as described above. For this reason, the interval between the upper wing plate 131 and the lower wing plate 132 (that is, the interval between the inner surface of the upper wing plate 131 and the inner surface of the lower wing plate 132) is formed by molding. Can have.

Therefore, the slider body 130 is not affected by the assembly accuracy when the slider body 130 is assembled, and it is difficult for the slider body 130 to be assembled to have a variation (error) in the interval between the upper and

lower blades

131 and 132. The size and shape of the element guide path at 130 can be stabilized.

As a result, since the posture and movement of the fastener element in the element guide path when the slider 120 slides can be stabilized, it is possible to stably ensure good slidability and operability of the slider 120.

International Publication No. 2014/006773 Pamphlet

In the slide fastener including the split type slider 120 as shown in FIG. 14 and FIG. 15, for example, when the left and right fastener tapes are pulled outward, the element elements in the left and right element rows are engaged with each other. A lateral pulling force is applied that pulls the rows outward in the tape width direction. Further, the slider 120 is subjected to stress that causes the element rows in the element guide path to contact the left and right lower flange portions 135 and presses the left and right lower flange portions 135 to the outside via the element rows.

Here, for example, in the case of a normal slider that is not a divided type, the left and right lower flange portions of the slider body are integrated with the lower wing plate, and the inner surface of the lower wing plate corresponding to the size of the fastener element ( It protrudes from the element guide surface.

On the other hand, in the split type slider 120 of Patent Document 1, the lower wing plate 132 is formed of an upper first lower wing split portion 137 and a lower second lower wing split portion 138, which has a large height. It has a size. Further, since the left and right lower flange portions 135 are provided to protrude upward from the lower second lower blade split portion 138 beyond the first lower blade split portion 137, the lower flange portion 135 itself The height dimension (that is, the height dimension from the second lower blade split portion 138 of the lower flange portion 135) is the height dimension of the lower flange portion in the normal slider (that is, the height from the lower blade plate of the lower flange portion). Larger than the size).

In the case of the split-type slider 120 having the long lower flange portion 135 having a large height as described above, the position where the lower flange portion 135 receives stress from the element row (the position of the force point), compared to the normal slider described above, The distance between the lower flange portion 135 and the position (fulcrum position) where the lower flange portion 135 is connected and integrated with the lower blade plate 132 (second lower blade split portion 138) is increased.

For this reason, for example, when a lateral pulling force is applied to the slide fastener and the left and right lower flange portions 135 are subjected to stress that is pressed outward via the element rows, the left and right lower flange portions 135 are applied according to the lever principle. However, the strength of the slider 120 with respect to the lateral pulling force tends to decrease.

Further, when the split type slider 120 in Patent Document 1 is attached to the element row of the fastener chain, the element row is inserted between the first lower blade split portion 137 and the upper blade plate 131 of the main member 140 as described above. After positioning, the assembling member 150 is fitted to the first lower blade split portion 137 of the main member 140 and assembled.

In this case, for example, when the fastener chain is attached to a fastener attaching member such as a bag, when the main member 140 is attached to the element row of the fastener chain, the first lower blade split portion 137 of the main member 140 is It is placed on the back side of the tape and hidden.

For this reason, when the worker performs the assembly work of the assembly member 150 with respect to the main member 140, both the first lower blade split portion 137 and the assembly member 150 of the main member 140 cannot be directly visually observed. However, the assembly work time may be longer than necessary.

The present invention has been made in view of the above-described conventional problems. A specific object of the present invention is to make it difficult for variations in the dimension between the first blade plate and the second blade plate in the slider body, and a slide fastener. Provided is a split type slider that can improve the strength of the slider with respect to the lateral pulling force when formed, and can be easily performed while visually observing the assembling operation of the assembling member with respect to the main member. In addition, another object of the present invention is to provide a slide fastener using the slider.

In order to achieve the above object, a slider for a slide fastener provided by the present invention has, as a basic configuration, a first blade plate, a second blade plate disposed to face the first blade plate, A slider body including at least a guide column connecting between one end portions of the first blade plate and the second blade plate and a pair of left and right first flange portions disposed on left and right side edge portions of the first blade plate; A guide surface of an element guide path that communicates the left and right shoulder openings disposed at the one end portion of the slider body and the rear opening disposed at the other end portion; and an inner surface of the first blade, the second A slider for a slide fastener formed by an inner surface of a vane plate and inner surfaces of a pair of left and right first flange portions, wherein the slider body is formed independently of the main member and the main member and the main body Assembled to the member An assembly member to be fixed, and the main member includes the first blade plate, a base portion including a part of the inner surface of the second blade plate, the guide pillar, and a pair of left and right first members. 1 flange part is integrally formed, and the assembly member has a remaining part of the inner surface of the second blade, and has an outer part that forms the second blade together with the base part. Is the most important feature.

In the slider according to the present invention, it is preferable that the outer portion has an accommodating space portion that accommodates a part of the base portion. The base portion is disposed at a center portion in the width direction of the second blade plate, and includes a base body portion forming the inner surface of the second blade plate, and left and right sides extending from the base body portion in the slider width direction. It is preferable that at least the left and right engaging piece portions of the base portion are fitted and accommodated in the accommodation space portion.

In this case, it is preferable that the outer portion includes a base insertion gap that allows the base body portion of the base portion to be inserted and forms a space continuous with the accommodation space portion. In addition, the outer portion extends from the left and right side edge portions of the outer wall portion toward the first blade plate, and the right and left side surfaces of the second blade plate. Left and right side wall portions, and left and right side wall portions extending in the slider width direction, and left and right inner wall portions forming the inner surface of the second vane plate, and the accommodating space portion includes the outer wall portion, It is preferable to be formed surrounded by the side wall portion and the inner wall portion.

Further, the base insertion gap is formed between the left and right inner wall portions, and the inner surface of the second blade plate formed by the main member, and the inner surface of the second blade plate formed by the assembly member. Are preferably coplanar. Furthermore, it is preferable that the width dimension of the base main body part in the base part is set to be equal to or larger than the width dimension of the guide column.

Furthermore, in the slider according to the present invention, one of the base portion and the outer portion has an engaging projection portion, and the other has an engaged hole portion or an engaged recessed portion for engaging the engaging projection portion. And at least one of the base portion and the outer portion is formed to be elastically deformable, and the outer portion is engaged with the base portion using the elastic deformation. It is preferable that it is fixed to the base portion so as to be immovable and separable.
In the present invention, the outer portion may be fixed to the base portion by adhesion or welding.

Furthermore, in the slider according to the present invention, the slider has a handle attached to be rotatable with respect to the slider body, and the slider body includes at least one of the main member and the assembly member. On the other hand, it is preferable to have a pull attachment portion for attaching the pull handle.
In the slider of the present invention, it is preferable that a pair of left and right second flange portions having the same height as the first flange portion is disposed on the left and right side edge portions of the second blade.

In the slide fastener provided by the present invention, the slider having the above-described configuration is mainly formed by being attached to an element row formed on the opposite side edges of the fastener tape in the left and right fastener stringers. It is a characteristic.

Further, in the slide fastener of the present invention, the element row is arranged from the outside between the left and right side edge portions of the base portion and the left and right first flange portions of the main member from the first blade plate and the base portion. A gap that can be inserted through the main body of the slider body and the left and right edges of the slider body fixed by assembling and fixing the assembly member to the main body is large. It is preferable that a tape insertion gap is provided.

As described above, the slide fastener slider according to the present invention is arranged on the first blade (for example, the lower blade), the second blade (for example, the upper blade), the guide column, and the first blade. And a split-type slider body having a pair of left and right first flange portions that are in contact with the element row of the slide fastener, and the slider body is formed independently of the main member and the main member. And an assembly member that is assembled and fixed to the main member.

The main member has a form in which a first blade, a base portion having a part of the inner surface of the second blade, a guide column, and a pair of left and right first flange portions are integrally formed. The assembly member includes a remaining portion of the inner surface of the second blade, and has an outer portion that forms the second blade together with the base portion.

In the slider body of the present invention formed from such a main member and an assembly member, the base portion of the main member is formed with a part of the inner surface of the second blade, and the assembly member The form which forms a 2nd blade with the outer shell part of this is provided. For this reason, when attaching a main member to the element row | line | column of a fastener chain, an element row | line | column can be easily inserted between the 1st blade board and base part of a main member. After that, by assembling the assembly member to the main member to form the slider body, the element row is stably held in the element guide path of the slider body, and the element row is, for example, on the left and right side edges of the slider body. It is possible to prevent the outer portion from slipping out through the formed tape insertion gap. 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 of the main member and the assembly member, the first blade plate and the base portion of the second blade plate in the main member are connected and integrated through the guide column. The distance (dimension) between the first blade and the second blade is less affected by the assembly accuracy when the assembly member is assembled to the main member, and the first and second blades are assembled for each slider to be assembled. It is possible to make it difficult for the gap between the plates to vary (error). Accordingly, the posture and movement of the fastener element in the element guide path when the slider slides are stabilized, and good slidability and operability of the slider can be stably secured.

Furthermore, in the slider body according to the present invention, as described above, the first blade is formed of a single member that is not divided, and the first flange portion is integrally formed on the left and right side edges of the first blade. Is formed. For this reason, in the present invention, unlike the case where, for example, the second lower wing split portion 138 that divides the lower wing plate 132 is provided with a long lower flange portion 135 as in the above-described Patent Document 1, the first flange portion is provided. It is possible to shorten the height dimension of the device itself in accordance with the size of the fastener element or the like (in other words, approximately the same size as that of a normal general slider body which is not a divided type).

Accordingly, when a slide fastener is formed using the slider of the present invention, even if a lateral pulling force is applied to the slide fastener, the position of the force point at which the first flange portion receives stress from the element row, and the first flange The position of the fulcrum where the part is connected and integrated with the first blade is not separated as in the case of the above-mentioned Patent Document 1, and the distance between the two is shortened in the same manner as a general slider body. can do. Accordingly, in the present invention, even if the slider body is formed in a divided type, the left and right first flange portions are less likely to be plastically deformed so that the slider strength against lateral pulling force is reduced. The problem in Patent Document 1 can be solved.

In addition, when the slider of the present invention is used for, for example, a so-called reverse use type slide fastener, when the main member is attached to the element row of the fastener chain in a state where the fastener chain is attached to a fastener attaching member such as a bag. In addition, the base portion of the second blade plate (in this case, the upper blade plate) in the main member is disposed at a position where it can be seen on the tape surface side of the fastener tape.

For this reason, when attaching the slider to the element row of the fastener chain, the operator attaches the assembly member to the base portion while observing both the base portion and the assembly member of the second blade plate of the main member. Since the slider body can be formed, the assembly work of the slider body can be easily performed in a short time.

In such a slider of the present invention, the outer portion of the assembly member has an accommodating space for accommodating a part of the base portion. Thereby, an assembly member can be easily assembled and fixed to a base part.

In particular, in the present invention, the base portion of the main member is disposed at the center in the width direction of the second blade, and extends in the slider width direction from the base body that forms the inner surface of the second blade. Left and right locking piece portions, and at least the left and right locking piece portions of the base portion are fitted and accommodated in the accommodation space portion of the assembly member. Further, the outer portion of the assembly member includes a base insertion gap that allows the base body portion of the base portion to be inserted and forms a space continuous with the accommodation space portion.

As a result, the assembly member can be easily moved to the base portion without shifting the position of the assembly member with respect to the main member by sliding the assembly member in the slider length direction with respect to the base portion of the main member. It can be assembled and fixed stably. Further, even if the slider is slid along the element row of the slide fastener, the assembly member is hardly detached from the main member, and the fixed state of the assembly member with respect to the main member can be stably maintained.

In this case, the outer shell portion of the assembly member extends from the left and right side edges of the outer wall portion toward the first blade plate, and the outer blade portion is disposed on the surface of the second blade plate facing the vertical direction. Left and right side wall portions that form the left and right side surfaces of the plate, and left and right inner wall portions that extend from the left and right side wall portions in the slider width direction and form the inner surface of the second vane plate are provided. Further, the housing space portion of the outer portion is formed so as to be surrounded by the outer wall portion, the side wall portion, and the inner wall portion.

As a result, the housing space for accommodating a part of the base body portion of the base portion and the left and right locking pieces is stably formed in the outer portion of the assembly member. It is firmly assembled and fixed. For this reason, even if the slider is slid, it is possible to make it difficult to remove the assembly member from the main member.

In the present invention, the base insertion gap of the assembly member is formed between the left and right inner walls of the assembly member, the inner surface of the second blade formed by the main member, and the first member formed by the assembly member. The inner surface of the two blades is formed on the same surface. Thus, when the slider obtained by assembling the assembly member to the main member is slid along the element row of the slide fastener, the element row is prevented from being caught on the inner surface of the second blade, and the slider The sliding operation can be performed smoothly.

In such a slider of the present invention, the width of the base main body in the base of the main member is set to the same size as the width of the guide column, so that the strength of the base can be appropriately secured. Moreover, when attaching a main member to the element row | line | column of a fastener chain, an element row | line | column can be easily inserted between the 1st blade board and base part of a main member. Further, in the present invention, the width dimension of the base main body portion in the base portion of the main member can be set larger than the width dimension of the guide column, and thereby the strength of the base portion can be further increased.

In the slider of the present invention, one of the base portion and the outer portion has an engaging protrusion, and the other of the base portion and the outer portion has an engaged hole portion or an engaged concave portion for engaging the engaging protrusion portion. Have. Further, at least one of the base portion and the outer portion is formed so as to be elastically deformable. As a result, when the assembly member is assembled to the main member, the outer portion can be engaged with the base portion by utilizing the elastic deformation described above, thereby making the assembly member immovable with respect to the main member and It can be fixed separably.

In the present invention, the outer portion of the assembly member may be fixed to the base portion of the main member by adhesion or welding. Thereby, the assembly member can be more firmly fixed to the main member.

The slider of the present invention has a handle that is pivotably attached to the slider body, and the slider body has a handle attachment portion for attaching the handle to at least one of the main member and the assembly member. Have. With such a slider of the present invention, the slider can be easily and smoothly slid along the element row of the slide fastener by pulling while pulling the handle with a finger. In the present invention, the slider can be formed without providing a handle.

In the present invention, it is possible to provide a pair of left and right second flange portions having a height dimension smaller than that of the first flange portion on the left and right side edge portions of the second blade plate. For example, it can be suitably used for a slide fastener in which a coiled or zigzag element array is formed on one tape surface of the fastener tape. Furthermore, a pair of left and right second flange portions having the same height as the first flange portion can be provided on the left and right side edge portions of the second blade. Such a slider is suitably used for, for example, a slide fastener to which a plurality of injection-molded fastener elements or metal fastener elements are attached over both the front and back tape surfaces of the fastener tape.

In the present invention, there is provided a slide fastener in which the slider having the above-described configuration is attached to an element row formed on the opposite side edge portion of the fastener tape in the left and right fastener stringers.

In the case of the slide fastener of the present invention using the above-mentioned slider, for example, after attaching the fastener chain to a fastener-attached product such as a bag, or at the front end portion and the rear end portion of the fastener chain, a stopper or a release fitting insert is provided. Even after attachment, a slide fastener can be easily formed by attaching a slider to the element row of the fastener chain. Furthermore, for example, when the slider of the slide fastener is broken, the function of the slide fastener can be recovered by attaching the slider to the fastener chain from which the broken slider is removed from the element row.

In the slide fastener of the present invention, the element row can be inserted between the first blade and the base portion from the outside between the left and right side edge portions of the base portion and the left and right first flange portions of the main member.

In addition, as shown in FIG. 5, the slider body 10 according to the first embodiment includes two members, a main member (first slider member) 20 and an assembly member (second slider member) 30 that can be assembled to each other. The slider body 10 is formed by assembling and fixing the assembly member 30 to the main member 20.

Further, the assembly member 30 is assembled and fixed in a state where the element row 8 of the slide fastener 6 is inserted into the main member 20, so that the slider body 10 is simultaneously formed with the element row of the slide fastener 6. 8 can be attached.

The main member 20 of the first embodiment is integrally formed as a whole by die-casting a metal material. The main member 20 includes a base portion 21 that forms a part of the upper wing plate 11 in the slider body 10, the entire lower wing plate 12, guide pillars 13, and left and right lower flange portions 16. The main member 20 can be integrally formed as a whole by injection molding a thermoplastic resin material.

Here, the base part 21 forms the upper blade 11 together with the outer part 31 by assembling an outer part 31 described later of the assembly member 30. In this case, the inner surface of the upper blade 11 is formed by both the base portion 21 of the main member 20 and the outer portion 31 of the assembly member 30, and the position of the boundary portion between the main member 20 and the assembly member 30 is The inner surface of the upper blade 11 is set to be separated.

In particular, of the inner surface (element guide surface) of the upper wing plate 11, the inner surface at the rear end portion of the upper wing plate 11, the inner surface of the base portion 21 in the main member 20, and the outer portion 31 (described later) in the assembly member 30. The inner surface of the inner wall portion 35) of the outer shell portion 31 is formed on the same flat surface, and the rear end portion of the upper blade 11 has a flat inner surface. On the other hand, on the inner surface of the intermediate portion between the guide column 13 and the rear end portion of the upper blade plate 11, the inner surface of the base portion 21 of the main member 20 is lower than the inner surface of the outer shell portion 31 of the assembly member 30. It is arranged to protrude toward the plate 12 side. In this way, by projecting a predetermined portion of the base portion 21 of the main member 20 from the outer portion 31, the above-described upper partition portion 11a of the upper blade 11 is formed.

The base portion 21 of the main member 20 is connected to the upper end portion of the guide column 13 and is located at the rear end position (lower side) of the upper wing plate 11 from the center position in the front-rear direction of the guide column 13 toward the rear. It extends to the same position as the rear end position of the blade 12).

The base portion 21 is disposed at the center portion in the width direction and has a base body portion 22 having a certain height, and left and right locking pieces 23 extending from the upper end portion of the base body portion 22 to the left and right. And an engaging protrusion 24 projecting from the upper surface of the base body portion 22 and a recessed portion 25 recessed from the upper surface of the rear end portion of the base body portion 22.

The base body 22 of the first embodiment is arranged at the center in the width direction of the upper blade 11 and has a constant width dimension over the entire length. The base main body portion 22 forms the above-described upper middle partition portion 11a of the upper wing plate 11, and forms the inner surface of the central region in the width direction on the rear side of the guide pillar 13 among the inner surfaces of the upper wing plate 11. .

In this case, the width dimension of the base main body portion 22 is set to be equal to or larger than the maximum value of the width dimension of the guide column 13. Actually, the width dimension of the base main body portion 22 in the first embodiment is set to the same size as the maximum width dimension of the guide pillar 13. By forming the base body portion 22 with a width dimension equal to or greater than the maximum width dimension of the guide column 13, the strength of the base portion 21 can be stably secured.

In addition, since the base body 22 is formed with a width dimension that is equal to or greater than the maximum width dimension of the guide column 13, the boundary position between the inner surface of the upper blade 11 of the main member 20 and the assembly member 30 is Since it is possible to avoid meshing and a portion for releasing the meshing, the slider can be slid stably.

In addition, although the intensity | strength of the base part 21 can be raised by enlarging the width dimension of the base main-body part 22, when the width dimension of the base main-body part 22 is enlarged too much, the lower wall of the assembly member 30 mentioned later Since the width dimension of the part 35 becomes small, there is a possibility that the strength of the outer shell part 31 in the assembly member 30 and the assembly strength of the assembly member 30 with respect to the main member 20 are lowered. Therefore, the width dimension of the base body portion 22 is set to 120% or less of the maximum width dimension of the guide column 13, particularly the same as the maximum width dimension of the guide column 13 as described above. It is preferred that

Furthermore, by setting the width dimension of the base body portion 22 as described above, it becomes easy to ensure a wide space (shortest distance) between the base portion 21 and the lower flange portion 16. For example, the slider body 10 is assembled. At the same time, when attaching to the element row 8, the element row 8 is easily inserted from the outside of the main member 20 between the base portion 21 and the lower blade 12 through the base portion 21 and the lower flange portion 16. be able to.

The left and right locking piece portions 23 in the base portion 21 are arranged in parallel to the lower blade 12 with a certain height from the upper end portion of the base main body portion 22 toward the left and right outer sides. In this case, the left locking piece portion 23 and the right locking piece portion 23 are formed symmetrically with the base body portion 22 interposed therebetween. Further, the upper surfaces of the left and right locking piece portions 23 form a single plane with the upper surface of the base main body portion 22.

In the first embodiment, the width dimension between the left edge (tip edge) of the left locking piece 23 and the right edge (tip edge) of the right locking piece 23 is the same as that of the left and right lower flange portions 16. It is larger than the width dimension between the inner surfaces and smaller than the width dimension between the outer surfaces of the left and right lower flange portions 16 (see FIG. 6).

By setting the size of the left and right locking pieces 23 as described above, the strength of the locking pieces 23 and the strength of the outer shell 31 described later of the mounting member 30 can be appropriately secured, and the mounting is performed. The member 30 can be easily assembled to the base portion 21 of the main member 20.

In these left and right locking piece portions 23, the outer peripheral edge portion excluding the rear end edge portion has a curved shape such that the upper ridge line portion and the lower ridge line portion are chamfered. In addition, the outer corners at the front end portions of the left and right locking pieces 23 have a circular arc shape in plan view as if chamfered.

Thus, when the left and right locking pieces 23 are provided with a rounded shape that has been chamfered as described above, the left and right locking pieces 23 are locked when the assembly member 30 is assembled to the main member 20. The piece portion 23 can be easily inserted into a storage space portion 37 described later of the outer shell portion 31 of the assembly member 30.

The engaging protrusion 24 in the base portion 21 protrudes from the upper surface of the central portion in the width direction of the base main body portion 22 and has a substantially rectangular shape in plan view. The engagement protrusions 24 are perpendicular to the upper surface of the base body 22 and are directed rearwardly toward the rear, left and right side surfaces disposed on the left and right sides in the width direction, and forward from the upper end of the rear end surface. And an inclined surface inclined downward. Further, the engagement protrusion 24 has a shape that gradually decreases the height dimension from the rear end face toward the front.

In the first embodiment, the position at which the engagement protrusion 24 is provided is not particularly limited. For example, the engagement protrusion 24 can be provided on the upper surface of the left and right locking pieces 23 instead of the upper surface of the base body 22. . For example, in order to make it easy to assemble and fix the assembly member 30 to the main member 20, the engagement protrusion 24 is formed at the center in the width direction on the upper surface of the base body 22 and the length of the base body 22. It is preferable to be provided at a position behind the center of the direction.

The recessed portion 25 of the base portion 21 is disposed in a region on the rear side of the engaging protrusion 24 at the center portion in the width direction of the base body portion 22, and forward from the position of the rear edge of the base body portion 22. The base body 22 is recessed so as to be recessed from the upper surface.

By providing the recessed portion 25, after the assembly member 30 is assembled and fixed to the main member 20 to form the slider body 10, the assembly member 30 is detached from the main member 20 and the slider body 10 is disassembled. In this case, it is possible to disengage the assembly member 30 from the main member 20 by inserting a rod-shaped member (not shown) into the recessed portion 25 and pressing the assembly member 30 with the rod-shaped member to cause elastic deformation. Become.

In the main member 20 of the first embodiment, the distance between the side edge portions of the left and right locking piece portions 23 in the base portion 21 and the left and right lower flange portions 16 (in other words, the side edge portion of the locking piece portion 23). The shortest distance connecting the upper flange portion 16 and the lower flange portion 16) is set larger than the vertical dimension of the element row 8 of the slide fastener 6. In this way, by setting the distance between the side edge portions of the left and right locking piece portions 23 and the left and right lower flange portions 16 to an interval at which the element row 8 can be inserted, the outer side of the main member 20 is set. Therefore, it can be inserted between the base portion 21 and the lower blade 12 through the side edge portion of the locking piece portion 23 and the lower flange portion 16.

The entire assembly member 30 in the first embodiment is integrally formed by injection molding a thermoplastic resin material. The assembly member 30 includes an outer shell portion 31 that forms a remaining portion of the slider body 10 excluding the base portion 21 of the upper blade 11, a pull attachment portion 14, and left and right upper flange portions 15.

The outer shell portion 31 of the assembly member 30 includes a front wall portion 32 that forms the front end surface of the outer shell portion 31, an upper wall portion (outer wall portion) 33 that forms the upper surface of the upper blade 11, and the left and right sides of the upper wall portion 33. Left and right side wall portions 34 extending downward from the side edge portions, and left and right lower wall portions (inner wall portions) 35 extending inward in the width direction from the lower ends of the left and right side wall portions 34 are provided.

In this case, the front end portion of the upper wall portion 33, the front end portions of the left and right side wall portions 34, and the front end portions of the left and right lower wall portions 35 are connected and integrated with the front wall portion 32. Further, the handle attachment portion 14 is integrally provided on the upper wall portion 33 of the outer shell portion 31, and the left and right upper flange portions 15 are integrally provided on the lower ends of the left and right side wall portions 34.

Further, the outer shell portion 31 is formed so as to be surrounded by a base insertion gap 36 formed between the left and right lower wall portions 35, the upper wall portion 33, the left and right side wall portions 34, and the left and right lower wall portions 35. A housing space 37. The base insertion gap 36 and the accommodation space portion 37 open at the rear end of the outer portion 31 and are formed along the front-rear direction from the rear end of the outer portion 31 to the front wall portion 32. Further, the base insertion gap 36 and the accommodation space portion 37 form a continuous space that is not separated from each other.

The base body 22 of the main member 20 is inserted into the base insertion gap 36 of the outer shell 31 (the gap between the left and right lower wall portions 35) when the assembly member 30 is assembled to the main member 20. In the housing space 37 of the outer shell 31, the upper end portion of the base main body portion 22 and the left and right locking piece portions 23 in the main member 20 are fitted and housed.

Accordingly, the base insertion gap 36 of the outer portion 31 has a size that allows the base main body portion 22 of the main member 20 to be inserted without a gap, and the accommodation space portion 37 of the outer portion 31 has a base main body portion. It has a shape and size that allows the upper end portion of 22 and the left and right locking piece portions 23 to be fitted without gaps.

The inner surface (lower surface) of the upper wall portion 33 of the outer shell portion 31 is formed as a flat surface so that the upper surface of the base main body portion 22 and the upper surfaces of the left and right locking piece portions 23 of the main member 20 can be slidably contacted. . The inner surfaces (upper surfaces) of the left and right lower wall portions 35 are provided at the rear end portion of the lower wall portion 35, and include inclined surfaces 35a that are inclined downward toward the rear. The inner surfaces (upper surfaces) of the left and right lower wall portions 35 are arranged in front of the inclined surface 35a and have parallel surfaces 35b parallel to the inner surface of the upper wall portion 33 (see FIG. 7). As described above, the inclined surface 35 a is provided on the inner surface (upper surface) of the rear end portion of the lower wall portion 35, so that the left and right locking piece portions 23 in the base portion 21 are inserted into the accommodation space portion 37 of the outer shell portion 31. It can be made easy.

In addition, an engaged hole 38 that engages and engages an engaging protrusion 24 provided on the base 21 of the main member 20 on the upper wall 33 of the outer shell 31 in the first embodiment, and an engaged A slit 39 is formed from the hole 38 to the rear edge of the upper wall 33.

The engaged hole portion 38 of the outer shell portion 31 penetrates the upper wall portion 33 in the vertical direction and has a shape and a size capable of fitting the engaging protrusion portion 24. In the first embodiment, instead of providing the above-described engaged hole 38 in the outer shell 31, the inner wall of the upper wall 33 is engaged without penetrating the upper wall 33 in the vertical direction. It is also possible to provide an engaged recess into which the protrusion 24 can be fitted.

The width dimension of the slit part 39 in the outer shell part 31 is set smaller than the width dimension of the engaged hole part 38. The slit portion 39 of the outer shell portion 31 is formed by gradually increasing the slit width from the engaged hole portion 38 toward the rear. By providing the slit portion 39, the rear end portion of the upper wall portion 33 is divided into left and right portions so that the rear end portion is easily elastically deformed in the vertical direction.

When assembling the slider body 10 of the first embodiment using the main member 20 and the assembly member 30 as described above, the assembly member 30 is moved from the front side of the main member 20 to the base portion 21 of the main member 20. The assembly member 30 is assembled and fixed to the base portion 21 by sliding backward.

More specifically, first, the assembly member 30 is disposed in front of the main member 20, and the position of the outer portion 31 of the assembly member 30 is matched with the position of the base portion 21 of the main member 20. Subsequently, the base member 20 is inserted into the base insertion gap 36 and the accommodation space 37 provided in the outer portion 31 of the assembly member 30 while the assembly member 30 is slid relatively backward with respect to the main member 20. The part 21 is inserted. At this time, since the inclined surface 35 a is provided on the inner surface of the rear end portion of the lower wall portion 35 in the outer shell portion 31, the left and right locking pieces 23 of the base portion 21 can be easily placed in the housing space portion 37 of the outer shell portion 31. Can be inserted.

Subsequently, by sliding the assembly member 30 further rearward, the rear end portion sandwiching the slit portion 39 of the upper wall portion 33 in the outer shell portion 31 of the assembly member 30 is engaged with the main member 20. It is lifted little by little by the inclined surface of the protrusion 24 and gradually elastically deforms. At this time, the rear end portion of the upper wall portion 33 in the outer shell portion 31 can be easily elastically deformed by the formation of the slit portion 39 and can get over the engaging projection portion 24. In addition, the slit part 39 does not need to be formed, and in this case, the engaging projection part 24 can be guided to the engaged hole part 38 by elastically deforming the outer shell part 31 itself.

Then, when the rear end portion of the upper wall portion 33 in the outer shell 31 completely gets over the engagement protrusion 24, the rear end portion is elastically restored, and at the same time, the engagement protrusion 24 of the main member 20 is It fits in the to-be-engaged hole 38 of 31. As a result, the assembly member 30 is assembled to the main member 20 by engagement (snap engagement) and fixed immovably. Therefore, the slider body 10 of the first embodiment including the main member 20 and the assembly member 30 is provided. It is formed.

Here, fixing fixedly is easy even if a weak external force is applied so that the assembly member 30 does not move relative to the main member 20 (for example, does not rattle or swing). Means that it can be firmly attached with a fixing strength that does not separate.

It should be noted that the slider body 10 of the first embodiment assembled in this manner using snap engagement can be separated again into the main member 20 and the assembly member 30. For example, the tip of a thin rod-shaped member is inserted into a recessed portion 25 provided at the rear end of the base portion 21, and the rear portion of the upper wall 33 in the outer shell 31 of the assembly member 30 is further inserted at the tip of the rod-shaped member. The assembly member 30 is slid forward relative to the main member 20 while elastically deforming by pressing the end upward.

As a result, the engaging protrusion 24 of the main member 20 is extracted from the engaged hole 38 of the outer shell 31, and the rear end of the upper wall 33 in the outer shell 31 gets over the engaging protrusion 24. The main member 20 and the assembly member 30 can be disengaged. Then, the base portion 21 of the main member 20 is moved from the base insertion gap 36 and the accommodation space portion 37 provided in the outer portion 31 of the assembly member 30 by relatively sliding the assembly member 30 forward. Since it can be removed, the main member 20 and the assembly member 30 can be easily separated.

As described above, the slider body 10 of the first embodiment assembled using the main member 20 and the assembly member 30 is easily attached to a fastener chain in which a part of the left and right element rows 8 is separated, for example. Is possible.

Specifically, first, in the portion where the left and right element rows 8 in the fastener chain are separated, the left and right element rows 8 are connected to the left and right locking pieces 23 of the base portion 21 and the lower flange portion 16 of the main member 20. It inserts between the base part 21 and the lower blade 12 through the gap | interval between. Further, the main member 20 and the element row 8 are relatively positioned.

The assembled slider body 90 of the third embodiment can be separated again into the main member 100 and the assembly member 110, as in the case of the first embodiment.

As described above, the slider body 90 of the third embodiment assembled using the main member 100 and the assembly member 110 can be easily and efficiently formed into, for example, a fastener chain in which parts of the left and right element rows are separated. Can be attached. Further, by using the slider 3 of the third embodiment, for example, when a part of the slider 3 is damaged in the slide fastener 6b attached to a fastener-attached product such as a bag, the damaged slider 3 is damaged. Since the slider 3 according to the third embodiment can be replaced and the slide fastener 6b can be repaired easily.

Further, the slider body 90 in the third embodiment can smoothly engage and separate the left and right element rows as well as the slider body 10 in the above-described first embodiment, and also has good slidability of the slider 3. And the effect of ensuring operability can be obtained.

Further, even when a lateral pulling force is applied to the slide fastener 6b having the slider 3 of the third embodiment, the left and right lower flange portions 96 in the slider body 90 of the third embodiment have the slider body 10 in the first embodiment described above. As in the case of the above, the position of the force point at which the lower flange portion 96 receives stress from the element row and the position of the fulcrum where the lower flange portion 96 is connected to the lower blade 92 are not separated. The strength against the lateral pulling force can be increased.

In addition, in the third embodiment, when a lateral pulling force is applied to the slide fastener 6b, both the upper flange portion 95 and the lower flange portion 96 of the slider body 90 are subjected to stress by contacting the element row. For this reason, the magnitude of the stress applied to each of the upper flange portion 95 and the lower flange portion 96 can be reduced as compared with the case where the stress is received only by the lower flange portion 16 as in the first embodiment, for example. it can. Therefore, in the slider body 90 of the third embodiment, the left and right upper flange portions 95 and the left and right lower flange portions 96 are effectively prevented from being plastically deformed so as to be bent outward by a lateral pulling force. Can be made more difficult to break.

In the third embodiment, as in the first and second embodiments described above, the slider body 90 slides the assembly member 110 backward from the front side of the main member 100 to the main member 100. For example, the slider body may be formed so as to be assembled to the main member 100 by sliding the assembling member 110 forward from the rear side of the main member 100.

Further, the fixing means for assembling and fixing the assembly member 110 to the main member 100 is not limited to the snap engagement described above. For example, as described in the second embodiment with reference to the modification example, the assembly is performed. An adhesion means for adhering the outer shell portion 111 of the attachment member 110 to the base portion 101 of the main member 100 via an adhesive, or a welding means for welding the outer shell portion 111 of the attachment member 110 to the base portion 101 of the main member 100, It can be employed alone or in combination with snap engagement.

It is also possible to fix the assembly member 110 to the main member 100 by using such adhesion means and welding means. In particular, when only the adhering means or the welding means is employed, both the outer portion 111 of the assembly member 110 and the base portion 101 of the main member 100 are formed without providing the engaging protrusion and the engaged hole portion. It becomes possible.
