Description

  The present invention relates to a string fastener slider for opening and closing left and right element rows in which elements are fixed to a flexible core string at a predetermined pitch.

  In a conventional string fastener slider, a handle is generally used to improve a design composed of shape, pattern, color, or a combination thereof. For example, as an example of a conventional string fastener slider, a handle holding portion is fixed on the slider, and a decorative handle with a star pattern is rotatably attached to the handle holding portion. Exists (Patent Document 1). By the way, in this background art column, not only a plurality of components including the slider and the handle locking portion but also a single component of the slider is generically referred to as a slider body.

  In addition, the slider body disclosed as a drawing in Patent Document 1 includes an upper wing plate and a lower wing plate that are opposed to each other with a space in the vertical direction, and an upper wing plate and a lower wing plate from the left and right outer edges of the upper wing plate and the lower wing plate. And a flange projecting in the direction of narrowing the vertical interval. Although not shown in the figure, a guide column is interposed between the upper and lower blades and in the center in the left-right direction. This guide column branches the space in the slider body into a Y-shaped guide path, and the left and right elements. The elements in the row can be engaged and separated.

JP-A-2-159221

  By the way, in the conventional string fastener slider described above, the upper and lower blades are joined only in the range where the guide pillars exist, that is, in the left and right width central portions. That is, the upper and lower blades are not joined at the left and right width outer edges (in a range where the flange exists), and a gap is formed between the upper and lower flanges.

  Then, when external force is applied to the left and right width outer edges of the slider body (upper and lower wing plates), the external force is concentrated at the location where the upper and lower wing plates and the guide column are joined. In some cases, the guide column is deformed or broken. There is also a risk. In order to ensure the mechanical strength against such an external force, the left and right widths of the upper and lower blades cannot be made wide (long), in other words, it is desirable that the width be as narrow (short) as possible. Therefore, the shape of the upper and lower blades (slider body) is constrained by the shape of the inner path formed in the slider body (Y shape), and the shape is designed so that the left and right outer sides of the guide path can be partitioned by flanges. It is generally done. More specifically, the left and right lateral width of each flange is designed as a uniform width along the Y-shaped left and right outer shape of the guide path. Therefore, the outer shapes of the existing slider bodies are all uniform, making it difficult to redesign the slider body.

  The present invention was created in consideration of the above circumstances, and its purpose is to renew the design of the slider body.

  The present invention is predicated on a string fastener slider including a slider body in which a Y-shaped guide path for guiding the left and right element rows of the string fastener is formed. And the upper and lower wing plates facing each other in a vertically separated state, the guide column for joining the upper wing plate and the lower wing plate up and down on the inner sides of the left and right widths, the upper wing plate and the lower wing plate And left and right flanges on the left and right outer sides of the guide path. Each flange has a wide portion and a narrow portion with respect to the left and right widths.

The left and right flanges may be present only on a part of the entire length of the guide path on both the left and right sides of the guide path. To improve the mechanical strength at the left and right edges of the slider, the following may be used. good.
That is, the left and right flanges are continuous over the entire length of the guide path on both the left and right outer sides of the guide path.

Further, the left and right widths of each flange are not limited, but the following may be applied to give a new design to the slider body.
That is, the left and right widths of each flange are equal to or larger than the left and right widths of the corresponding one of the left and right element rows.

In order to give a new design to the slider body, the following may be performed.
That is, the left and right flanges have a left-right asymmetric shape centered on the guide path.

Furthermore, the slider should just have a slider main body at least. Therefore, the slider may have a slider body as a single component. However, in order to give a new design to the slider rather than the slider when the slider body is configured as a single component, the following may be used.
That is, the slider includes a slider body and a decorative body that is detachably connected to the slider body.

Furthermore, in order to give a new design to the slider, the following may be performed.
That is, the decorative body protrudes to the left and right of the upper wing plate in a state of being connected to the slider body.

  According to the present invention, the upper and lower blades that are separated from each other in the vertical direction are joined to the upper and lower sides of the guide path by the flanges on the upper and lower sides. Needless to say, the mechanical strength of the slider body is improved as compared with the conventional one, that is, the case where the left and right width side edges of the upper and lower blades are not joined by the flange. Therefore, it is also possible to increase the width of the slider body on the left and right compared to the conventional one, and by using this, each flange has a wide part and a narrow part on each side. Can be given.

  In addition, if the slider has a left and right flange that is continuous over the entire length of the guide path on both the left and right sides of the guide path, the mechanical strength at the left and right edges of the slider is further improved. It is possible to further expand and add a new design to the slider body.

  Furthermore, if the slider has a left and right width of each flange that is equal to or larger than the left and right width of the corresponding element in the left and right element rows, the slider body has a wider left and right width compared to the conventional one, giving the slider body a new design. Can be granted.

  Further, if the left and right flanges are asymmetrical with respect to the guide path, a new design can be imparted to the slider body.

  If the slider has a decorative body detachably connected to the slider body, the combination of the slider body design and the decorative body design becomes the slider design, giving the slider a new design. be able to.

  Furthermore, if the slider has a decorative body that protrudes to the left and right of the upper wing plate in a state of being connected to the slider body, a new design can be imparted to the slider by a decorative body that is wider to the left and right than the slider body. . Moreover, since the slider can be operated using the decorative body, the operability is also improved.

  FIG. 2 shows a string fastener 1 as an example to which the string fastener slider 4 of the first embodiment of the present invention is applied. The string fastener 1 includes a single fastener chain 2, a slider 4 according to the first embodiment for opening and closing two opposing element rows 2A of the fastener chain 2, and a stopper 3 for preventing the slider 4 from coming off. Is provided. Hereinafter, the direction in which the two element rows 2A are opposed to each other will be described as the left-right direction, the longitudinal direction of the element row 2A is the front-rear direction, and the direction orthogonal to the left-right direction and the front-back direction is the upper-lower direction.

  The fastener chain 2 has an element 22 and a flexible core string 21, and a number of elements 22 are fixed to the core string 21 at a constant pitch. Then, the element rows 2A formed in a single row are formed by the elements 22 arranged at a constant pitch, and this single row of the element rows 2A bends the core string 21 in a loop shape in the middle portion in the longitudinal direction. Thus, two element rows 2A are opposed to each other in almost half of the entire length in the longitudinal direction.

  The element 22 includes a fixing portion 22a attached to the core string 21 extending in the front-rear direction, and a meshing head 22b that protrudes laterally from the fixing portion 22a. The meshing head portion 22b has a shape in which the fixed portion 22a side is constricted back and forth and the tip side is enormous in the front and rear directions. Incidentally, in the illustrated example, the fixing portion 22a is attached to the core cord 21 in a state where the core cord 21 penetrates the inside of the fixing portion 22a.

  The stopper 3 has a cap shape, and is fixed to the fastener chain 2 by fitting both end portions of the fastener chain 2 formed into two meshed element rows 2A and 2A together into the cap shape. . Note that the stopper 3 and the element 22 may be formed of either synthetic resin or metal.

  As shown in FIGS. 1 and 2, the slider 4 of the first embodiment includes a slider body 5 that opens and closes two element rows 2 </ b> A and 2 </ b> A as a single component. The slider body 5 is a guide column that joins the upper and lower wing plates 51 and 52, which are opposed to each other in a state of being vertically separated, and the upper and lower wing plates 51 and 52 at the front part of the center of the left and right widths. 53, and left and right flanges 54, 54 that join the upper and lower blades 51, 52 over the entire length in the front-rear direction at the left and right width outer portions.

  The inner space formed between the upper and lower blades 51 and 52 is divided into left and right by the guide pillar 53 at the front part thereof, and the right and left outer sides are separated from the outside by the left and right flanges 54 and 54. The guide path 55 is Y-shaped. Therefore, the guide path 55 is opened only in the front-rear direction. Further, by moving the slider body 5 back and forth, the left and right elements 22 and 22 are engaged or separated in the guide path 55.

  The slider body 5 has a rectangular box shape because the upper and lower blades 51 and 52 are rectangular. In addition, since the upper and lower blades 51 and 52 arranged above and below the Y-shaped guide path 55 are symmetrically projected in the left and right directions, the left and right sandwiched between the upper and lower blades 51 and 52 are left and right. The flanges 54 and 54 are symmetrical. Further, the shape of the upper and lower blades 51 and 52 with respect to the guide path 55 is a shape that does not follow the left and right outer shapes of the guide path 55, that is, a rectangular shape in the illustrated example, so that the left and right flanges 54 and 54 have their left and right widths. (Thickness here) is non-uniform in the front-rear direction and has a relatively wide part (thick part) and a narrow part (thin part) with respect to the left and right widths. Yes. The front and rear end portions of each flange 54 are chamfered and rounded, but such a chamfered portion does not correspond to a narrow portion with respect to the left and right widths of each flange 54. Incidentally, if the upper and lower blades 51 and 52 are formed in a shape along the left and right outer shapes of the guide path 55, the flanges 54 are uniform with respect to the left and right widths.

  Since the slider 4 of the first embodiment described above is configured with the slider body 5 as a single component, the shape of the slider body 5 forms the skeleton of the design of the slider 4. Since the left and right flanges 54 and 54 join the upper and lower blades 51 and 52, the mechanical strength of the slider body 5 is improved.

  As shown in FIG. 3, the slider 4 according to the second embodiment of the present invention is configured with the slider body 5 as a single component as in the first embodiment. However, the slider main body 5 here is substantially different in shape of the upper and lower blades 51 and 52 and the left and right flanges 54 and 54 from the upper and lower blades 51 and 52 and the left and right flanges 54 and 54 in the first embodiment. . The upper and lower blades 51, 52 and the left and right flanges 54, 54 have a shape that protrudes greatly in the left-right direction and the front-rear direction with respect to the guide path 55, and the overall shape of the slider body 5 is a symmetrical ribbon tie shape. (The shape including the knot of the ribbon and both ends of the ribbon extending from the knot). Incidentally, the width of the upper and lower blades 51, 52 projecting left and right with respect to the guide path 55 and the left and right widths of the flanges 54, 54 are more detailed than the corresponding left and right widths of the left and right element rows 2A. Is larger than the left and right widths of the two meshed element rows 2A, 2A. Also, the fact that each flange 54 has a relatively wide portion and a narrow portion with respect to the left and right widths is the same as that of the first embodiment.

  Thus, by making the upper and lower blades 51 and 52 and the left and right flanges 54 and 54 project in the front-rear and right-and-left directions with respect to the guide path 55, the portion for gripping the slider body 5 becomes larger. It becomes easy to operate.

  As shown in FIG. 4, the slider 4 of the third embodiment of the present invention is configured with the slider body 5 as a single component as in the first embodiment. However, the shape of the upper and lower blades 51 and 52 and the left and right flanges 54 and 54 of the slider body 5 here is greatly different from that of the upper and lower blades 51 and 52 and the left and right flanges 54 and 54 in the first embodiment. The upper and lower blades 51 and 52 have a heart shape. In addition, the guide path 55 is formed such that the heart-shaped recess 51a and the V-shaped sharpened portion 51b on the opposite side are inclined to the left and right with respect to the front-rear direction (the longitudinal direction of the two element rows 2A and 2A). Is formed in the slider body 5. Accordingly, the upper and lower blades 51 and 52 and the left and right flanges 54 and 54 are asymmetric in the left-right direction. Incidentally, the fact that each flange 54 has a relatively wide portion and a narrow portion with respect to the left and right widths is the same as that of the first embodiment.

  The slider 4 of 4th Embodiment of this invention is comprised from the several component of the slider main body 5 and the decoration body 6 connected to the slider main body 5 so that attachment or detachment is possible, as shown in FIGS.

  The slider body 5 has a rectangular box shape similar to that of the first embodiment as a basic configuration. On the other hand, the decorative body 6 has a ribbon knot shape as the decorative body main body 61, and the knot portion of the ribbon knot has the same shape as the slider main body 5.

  The slider body 5 and the decorative body 6 are provided with a connecting portion 7 for detachably connecting the both. The connecting portion 7 includes a connecting concave portion 71 and a connecting convex portion 72 that can be fitted and released by a snap type, and the connecting concave portion 71 and the connecting convex portion 72 are provided separately in the slider body 5 and the decorative body 6. . In the illustrated example, the slider main body 5 is provided with a connecting concave portion 71, and the decorative body 6 is provided with a connecting convex portion 72.

  More specifically, the slider main body 5 is provided with a recessed recess 71a in a step shape in the left and right side surfaces (the left and right outer surfaces of the left and right flanges 54, 54) and in the middle part in the front-rear direction. . For this reason, having the relatively wide part and the narrow part regarding the left and right width of each flange 54 is the same as those of the first embodiment. In other words, the left and right side surfaces of the slider body 5 are stopper portions 71b that protrude in the left-right direction from the rectangular peripheral edge portions, and the locking recesses 71a are formed inside the stopper portions 71b. Accordingly, locking recesses 71a are provided on the left and right sides of the slider body 5, and the connecting recesses 71 are formed by these two locking recesses 71a and 71a.

  On the other hand, the decorative body 6 includes a connecting convex portion 72 on the back side of the decorative body main body 61. The connecting convex portion 72 is a back surface of the decorative body main body portion 61 and the left and right arm portions 72a and 72a projecting along the left and right outer surfaces of the flanges 54 and 54 from the left and right outer sides of the knot portion of the ribbon, It is comprised from the right and left latching convex parts 72b and 72b which protrude toward the left-right direction inner side from the front part of the arm parts 72a and 72a. Therefore, the front portions of the left and right engaging projections 72b and 72b are in a state of facing the inner side in the left-right direction. Thus, the connection convex part 72 is comprised from two latching convex parts 72b and 72b, and two arm part 72a and 72a for joining these latching convex parts 72b and 72b to the decoration body main-body part 61. FIG. ing.

  The slider body 5 includes a chamfered portion 71c chamfered so as to bulge a middle portion in the front-rear direction at a portion where the upper surface of the upper blade 51 and the left and right side surfaces of the left and right flanges 54, 54 are continuous. The chamfered portion 71c makes it easy to guide the connecting convex portion 72 (the pair of locking convex portions 72b and 72b) of the decorative body 6 to the connecting concave portion 71 (the pair of locking concave portions 71a and 71a).

  The slider 4 of the fourth embodiment described above attaches and detaches the slider body 5 and the decorative body 6 as follows. First, when the user aligns the left and right engaging projections 72b and 72b with the left and right chamfered portions 71c and 71c from the upper wing plate 51 side of the slider body 5, and pushes the decorative body 6 toward the slider body 5, the left and right While the arm portions 72a and 72a use their own elasticity to widen the space between the tips, the locking projection 72b slides on the surface of the chamfered portion 71c, and finally the locking projection 72b It fits into the locking recess 71a. When the decorative body 6 is connected to the slider main body 5 in this way, the locking convex portion 72b (the connecting convex portion 72) is positioned at the middle portion of the left and right widths of the decorative body 6. It protrudes to the left and right. Moreover, the slider main body 5 and the decorative body 6 are positioned by the fitting of the locking projection 72b and the locking recess 71a. When the user pulls the decorative body 6 upward away from the slider body 5 while pressing the slider body 5, the locking projection 72 b escapes from the locking recess 71 a. In such a manner, the decorative body 6 and the slider body 5 are detachable.

  As shown in FIGS. 8 and 9, the slider 4 of the fifth embodiment of the present invention is composed of a plurality of components including a slider body 5 and a decorative body 6, as in the fourth embodiment.

A locking recess 71a that surrounds the entire circumference of the slider body 5 is formed by the portions 71b, 71b and the four surfaces of the upper and lower blades 51, 52 and the left and right flanges 54, 54. Therefore, having the relatively wide part and the narrow part with respect to the left and right width of each flange 54 is the same as those of the first embodiment.

  The connection convex part 72 is formed on the back surface of the decorative body 6 in a state of penetrating in the front-rear direction a rectangular locking convex part 72b fitted into the locking concave part 71a. That is, in this embodiment, the connection convex part 72 is comprised only by the latching convex part 72b. It is desirable that the decorative body 6 including the connecting convex portions is formed of, for example, an elastomer such as synthetic rubber or silicon as a raw material, and imparts elasticity to the connecting convex portions 72. If the decorative body 6 including the connection convex portion 72 is formed of a synthetic resin having such elasticity, even if the slider body 5 including the connection concave portion 71 is formed of a hard resin, the connection protrusion 72 can be easily attached to and detached from the connecting recess 71.

  The slider 4 of the fifth embodiment is also in a state where the slider body 5 and the decorative body 6 are positioned when the slider body 5 and the decorative body 6 are connected by fitting the connecting concave portion 71 and the connecting convex portion 72. .

  As shown in FIG. 10, the slider 4 according to the sixth embodiment of the present invention is composed of a plurality of components including a slider body 5 and a decorative body 6 as in the fourth embodiment. The decorative body main body 61 of the decorative body 6 is different from the decorative body main body 61 used in the slider 4 of the fifth embodiment.

  The decorative body main body 61 here has a rectangular shape in which the left and right widths are wider than the front and rear widths, and the front and rear widths are approximately the same as the front and rear widths of the slider body 5. The dimensions are longer to the left and right than the slider body 5. Further, the upper surface of the decorative body main body 61 is provided with a combination of patterns and characters, and is arranged with a first pattern 61a surrounding the peripheral edge of the rectangle and an inner side with respect to the first pattern 61a. A rectangular second pattern 61b and a character 61c notated as a logo arranged inside the second pattern 61b are formed so as to protrude.

  As shown in FIGS. 11 to 13, the slider 4 according to the seventh embodiment of the present invention is composed of a plurality of components including a slider body 5 and a puller 8 that is pivotably connected to the slider body 5. The handle 8 has a decorative function. This will be described in detail below.

  Each flange 54 is bent along the left and right outer shapes of the guide path 55 having a Y-shape on the left and right inner surfaces, and the left and right outer surfaces are diagonally straight from the rear to the front. The left and right widths gradually widen from the rear to the front. Accordingly, each flange 54 has a relatively wide portion and a narrow portion with respect to the left and right widths, in common with those of the first embodiment.

  The pull handle 8 includes a pull handle main body 81 for picking with a finger and an annular portion 82 for connection to the slider main body 5, and the annular portion 82 is continuous with the pull handle main body 81. In the illustrated example, the handle main body has a pattern and a shape imitating one leaf, and is formed longer than the left and right and front and rear widths of the slider body 5.

  A puller attachment portion 56 that connects the annular portion 82 is formed on the surface of the upper blade 51. The pull attachment part 56 is composed of two parts, that is, an attachment part main body 56a and an attachment part sub-body 56b. The sub-subbody 5b is provided in a state of being divided in the front-rear direction. In the illustrated example, the handle attachment portion 56 is a surface of the upper wing plate 51 and is continuous to the front side (above the guide column 53), and a surface of the upper wing plate 51 and is continuous to the rear side. It is comprised from the attaching part subbody 56b to do.

  The attachment portion main body 56a mainly includes a curved body 56a1 that is curved in a concave shape toward the surface of the upper blade 51. The curved body 56a1 has a front end portion extending in the vertical direction and a lower end portion of the front end portion continuing to the upper wing plate 51, thereby being cantilevered by the upper wing plate 51. Further, before connecting the attachment portion main body 56a and the attachment portion sub-body 56b, the intermediate portion of the curved body 56a1 is inclined so as to gradually rise while extending from the front to the rear. Incidentally, the rear end portion of the curved body 56a1 extends in the vertical direction so as to descend toward the surface side of the upper blade 51.

  On the other hand, the attachment portion sub-body 56b is U-shaped in plan view and protrudes upward from the surface of the upper blade 51. That is, the attachment portion sub-body 56b is composed of a middle piece 56b1 and two side pieces 56b2 and 56b2 bent from the left and right sides of the middle piece 56b1. However, the upward protrusion of the middle piece 56b1 protrudes only below the rear end portion of the attachment portion main body 56a before the connection, and is between the rear end portion of the attachment portion main body 56a and the attachment portion sub-body 56b. Has a gap for allowing the annular portion 82 to pass therethrough. In addition, the upper end portion of the middle piece 56b1 has an engaged convex portion 56b3 protruding rearward. Incidentally, an engaging convex portion 56a2 that meshes with the engaged convex portion 56b3 on the lower side is provided so as to protrude forward from the lower end portion of the rear end portion of the curved body 56a1, and includes the engaging convex portion 56a2. The slider body 5 is preferably molded from a synthetic resin.

  When the slider body 5 and the handle 8 are connected to each other, the annular portion 82 is passed through the curved body 56a1, and then the rear end portion of the attachment portion main body 56a is attached to the attachment portion sub body 56b using the elasticity of the synthetic resin. And the engaging convex portion 56a2 is engaged with the lower side of the engaged convex portion 56b3. As a result, the annular portion 82 is attached to the handle attachment portion 56, and the handle 8 is rotatably connected to the slider body 4.

  Incidentally, in the various embodiments described above, the slider body 5 and the decorative body 6 may be integrally formed of any one of metal and synthetic resin. For example, in the case of a synthetic resin, engineering plastics or general-purpose plastics may be used. To make it more environmentally friendly, it is desirable to use general-purpose plastic.

  The present invention is not limited to the above embodiment. For example, in the case of the slider 4 as in the first to third embodiments in which the slider body 5 is a single component, the outer surface of the slider body 5 may be provided with a pattern or a color.
