Technical Field

The present invention relates to a slider.

Background

A conventional slide fastener generally includes a pair of fastener chains including a fastener tape and fastener elements, and a slider mounted on the fastener chains to open or close the fastener elements by sliding, and a pull tab may be further provided on the slider as required, so that a user may drive the slider to slide on the fastener chains by pulling the pull tab. When a garment manufacturer applies a zipper to a fabric (e.g., a jacket), the garment manufacturer often places a unique decorative pattern (e.g., logo) on the zipper tab to improve the brand recognition of the fabric being sold. Of course, manufacturers of slide fasteners also place their own trademark marks and the like on the tabs.

However, in the related art of slide fasteners, there are also slide fasteners that do not use a pull tab (i.e., a pull-tab-less type slide fastener). The pull-tab-less type slide fastener includes a pair of fastener stringers and a slider but does not have a pull tab. In the case of using no pull tab, it is difficult for a zipper manufacturer to design a decorative pattern required by a clothing manufacturer in the pull-tab-free type zipper in accordance with the requirements of the clothing manufacturer. In contrast, patent documents 1 and 2 in the related art documents propose a technique of providing a decorative material (an adhesive material or a colored paint) as a decorative layer on the surface of the slider. In addition, since the finger recess can be provided on the surface of the slider without using the pull tab, the user can press the finger recess with a finger and slide the slider with respect to the fastener chain. In contrast, patent document 3 in the related art document proposes to provide a finger recess on the surface of the slider.

Disclosure of Invention

Problems to be solved by the invention

As is clear from the above, when a decorative pattern is provided on a zipper of the pull-tab-less type, a decorative material (an adhesive material or a colored paint) is usually provided as a decorative layer on the surface of a slider (for example, patent documents 1 and 2). In order to form the decorative layer smoothly on the surface of the slider, a recessed portion is usually provided on the surface of the slider, and the decorative layer is fixed to the surface of the slider by filling the recessed portion. However, the recess is limited by the dimensions of the slider (e.g. the thickness of the slider), in particular by the thickness of the upper plate of the slider, and is usually only slightly recessed inwardly. Therefore, the decorative layer filled into the concave part has low bonding property with the concave part, so that the decorative layer is easy to fall off from the concave part. Further, in the case of a technique in which a finger recess is provided on the surface of the slider (for example, patent document 3), the above-described problem of the finger recess being limited by the size of the slider (for example, the thickness of the slider) causes limitation in the design and operation of the finger recess.

Means for solving the problems

The invention provides a slider, which is a slider for a slide fastener and comprises a slider main body and a decoration part. The slider body includes an upper plate, a lower plate, a connecting post connected between the upper plate and the lower plate, and a protrusion protruding from the upper plate. The decoration component is injection-molded around the protruding part and has a decoration surface.

In an embodiment of the present invention, the protrusion includes a first portion protruding from the upper plate and a second portion extending outward from the first portion, a length of the second portion is greater than a length of the first portion, and/or a width of the second portion is greater than a width of the first portion, so that the protrusion assumes an umbrella shape, and the decorative member is injection-molded on the protrusion from an upper side of the protrusion toward the upper plate and is located on the upper plate.

In an embodiment of the present invention, the length of the protrusion is smaller than the length of the upper plate, or the width of the protrusion is smaller than the width of the upper plate.

In an embodiment of the present invention, a thickness of the decoration member is smaller than a thickness of the slider body.

In an embodiment of the invention, the slider body further comprises a fin protruding from the upper plate on opposite sides of the protrusion.

In an embodiment of the present invention, the fin portion protrudes from a middle of the upper plate in a length direction in a manner of covering the groove.

In an embodiment of the present invention, the decorative member is injection molded from a rubber material.

ADVANTAGEOUS EFFECTS OF INVENTION

In view of the above, in the slider of the present invention, the decoration member is injection molded on the slider body, particularly, the decoration member is injection molded on the protrusion portion protruding from the upper plate of the slider body, and the decoration surface provided by the decoration member can be decorated as required (for example, a decoration layer having a specific pattern or a finger recess portion is provided). Compared with the prior art that the decorative layer or the finger recess is formed on the surface of the slider, the decorative part is further formed on the protruding part protruding outwards from the upper plate of the slider body, so that the stability of the slider body can be improved, the slider body can be prevented from falling off, the slider body can be set into a specific shape according to requirements, and a required decorative pattern or the finger recess is formed on the decorative surface of the slider body. Thus, the slider of the present invention can diversify the design and has good stability.

Detailed Description

Fig. 1 is a front explanatory view of a slider of an embodiment of the present invention. Fig. 2 is an exploded view of the slider of fig. 1. Fig. 3 is a side explanatory view of the slider of fig. 1. FIG. 4 is an exploded view of the pull head of FIG. 3. Referring to fig. 1 to 4, in the present embodiment, the slider 100 includes a slider main body 110 and an ornamental member 120. The slider body 110 includes an upper plate 112, a lower plate 114, a connecting post 116 connected between the upper plate 112 and the lower plate 114, and a protrusion 118 protruding from the upper plate 112. The decorative member 120 is injection-molded around the protrusion 118 and has a decorative surface 122. The slider 100 is adapted for a slide fastener (not shown). In particular, the slider of the present invention can be a slider suitable as a lower slider of a pair of sliders used in a double-end slide fastener.

Specifically, in the present embodiment, the slider 100 is generally composed of the slider body 110 and the decoration member 120, but not limited thereto. The length/width hereinafter refers to a size (corresponding to a reference numeral in the drawing) from one end of the portion to the other end on the opposite side in the length direction/width direction of the virtual plane on which the slider 100 is located, but is not limited thereto and may be adjusted as needed. In the slider body 110, the upper plate 112 and the lower plate 114 are substantially plate-shaped and disposed in parallel to each other, and for example, the length of the upper plate 112 is equal to the length of the lower plate 114 (for example, the length L1 in fig. 2), and the width of the upper plate 112 is equal to the width of the lower plate 114 (for example, the width W1 in fig. 4), but the invention is not limited thereto. In other embodiments, not shown, the upper plate 112 and the lower plate 114 may have different shapes. The connecting column 116 has a cylindrical shape and is connected between the upper plate 112 and the lower plate 114. Preferably, the dimension of the connecting column 116 (e.g., length L2 of fig. 2/width W2 of fig. 4) is smaller than the dimension of the upper plate 112 or the dimension of the lower plate 114 (e.g., length L1 of fig. 2/width W1 of fig. 4), such that a space S exists between the upper plate 112 and the lower plate 114, but not limited thereto. When the slider 100 is applied to a fastener chain (not shown) to constitute a slide fastener, the slider body 110 can be mounted on elements (not shown) of the fastener chain such that the elements penetrate into a space S between the upper plate 112 and the lower plate 114. In this manner, the slider 100 can open or close the fastener elements by sliding the slider body 110 over the fastener stringer.

Further, in the present embodiment, the slider body 110 includes a projection 118 projecting from the upper plate 112. More specifically, the protrusion 118 includes a first portion 118a protruding from the upper plate 112 and a second portion 118b extending outwardly from the first portion 118 a. Preferably, the dimension of the second portion 118b (e.g., length L3 of fig. 2/width W3 of fig. 4) is greater than the dimension of the first portion 118a (e.g., length L4 of fig. 2/width W4 of fig. 4), e.g., the first portion 118a is cylindrical, and the second portion 118b is plate-shaped, with channels 118c formed between the second portion 118b, the upper plate 112, and the sides of the first portion 118 a. As such, rather than the protrusion 118 exhibiting a uniform length or a uniform width, the dimension of the upper side (i.e., the second portion 118b) (e.g., the length L3 of fig. 2/the width W3 of fig. 4) is greater than the dimension of the lower side (i.e., the first portion 118a) (e.g., the length L4 of fig. 2/the width W4 of fig. 4), such that the protrusion 118 exhibits an umbrella, or mushroom, shape. As such, the above design facilitates the placement of the decorative member 120 (see the following description).

Specifically, the decorative member 120 is injection-molded around the protrusion 118 from a rubber material (for example, but not limited to, natural rubber, synthetic rubber, urethane rubber, fluorine rubber, various elastomers, and silicon) and has a decorative surface 122. More specifically, the decorative member 120 is injection-molded on the upper plate 112 from the upper side of the protrusion 118 (i.e., the second portion 118b) toward the upper plate 112 from the protrusion 118. Preferably, the decorative member 120 covers the entire protrusion 118, i.e., the decorative member 120 contacts the first portion 118a, the second portion 118b, and the groove 118c, and further contacts the upper plate 112. In other words, since the protrusion 118 of the present embodiment is umbrella-shaped (or mushroom-shaped), that is, the size of the second portion 118b (e.g., the length L3 of fig. 2/the width W3 of fig. 4) is greater than the size of the first portion 118a (e.g., the length L4 of fig. 2/the width W4 of fig. 4), and the groove 118c is formed between the second portion 118b, the upper plate 112, and the side edge of the first portion 118a, when the decorative member 120 is injection-molded around the protrusion 118, the decorative member 120 covers the first portion 118a and the second portion 118b of the protrusion 118 to be filled in the groove 118c, and preferably further contacts the surface of the top surface of the upper plate 112 facing the groove 118 c. In this way, the decorative member 120 can interfere with the protrusion 118 having an umbrella (or mushroom) shape, and can be stably formed on the protrusion 118. That is, the protrusion 118 facilitates the provision of the decorative member 120. However, in other embodiments (not shown), the protrusion may be in other embodiments (for example, a convex pillar with a uniform length or a uniform width is adopted), and the invention is not limited thereto. The provision of the decorative member 120 can be facilitated as long as the slider body 110 has the projection 118 projecting from the upper plate 112.

Further, in the present embodiment, the size of the protrusion 118 (e.g., length L3 or L4 of fig. 2/width W3 or W4 of fig. 4) is smaller than the size of the upper plate 112 (e.g., length L1 of fig. 2/width W1 of fig. 4). In the case where the decorative member 120 is injection-molded to the protrusion 118, the decorative member 120 contacts the surface of the top surface of the upper plate 112 facing the groove 118c, and the dimension of the decorative member 120 (e.g., the length L5 of fig. 2/the width W5 of fig. 4) is smaller than or equal to the dimension of the upper plate 112 (e.g., the length L1 of fig. 2/the width W1 of fig. 4). As such, the decorative member 120 has a similar outer profile as the slider body 110, and it is preferable that the decorative member 120 covers the entire surface of the top surface of the upper plate 112 facing the groove 118c to reduce the exposed portion of the surface of the upper plate 112, so that the slider 100 has an aesthetically excellent appearance. However, in other embodiments, not shown, the decorative member 120 can cover only a part of the protrusion 118 (i.e., the size (e.g., length/width) of the decorative member 120 is smaller than the size (e.g., length/width) of the protrusion 118) or extend to the outside of the protrusion 118 (i.e., the size (e.g., length/width) of the decorative member 120 is larger than the size (e.g., length/width) of the protrusion 118), or further cover the side edge of the upper plate 112.

In addition, in the present embodiment, the thickness d1 of the decorative member 120 is greater than the thickness d2 of the protrusion 118, but less than the thickness d3 of the attachment post 116 (i.e., the height of the distance/space S between the upper plate 112 and the lower plate 114), or less than the overall thickness of the slider body 110 (i.e., the sum of the thicknesses d2 and d 3). However, in other embodiments not shown, the thickness d1 of the decorative member 120 may be adjusted to be smaller than the thickness d2 of the protrusion 118 (e.g., the decorative member 120 only covers the second portion 118b and does not fill the groove 118 c), or the thickness d1 of the decorative member 120 may be adjusted to be larger than the thickness d3 of the attachment post 116 (i.e., the height of the distance/space S between the upper plate 112 and the lower plate 114) and even larger than the entire thickness of the slider body 110 (i.e., the sum of the thicknesses d2 and d 3). Alternatively, the thickness d1 of the decorative member 120 may be adjusted to be a non-uniform thickness or to have a specific shape for the decorative member 120. The present invention does not limit the specific shape of the decoration member 120 as long as the design of the decoration member 120 does not interfere with the sliding of the slider body 110 on the fastener chain, which can be adjusted as required.

Further, the decoration member 120 has a decoration surface 122, and the decoration surface 122 refers to an outer surface of the decoration member 120 opposite to the slider body 110. When the slider 100 is applied to a fastener chain (not shown) to form a slide fastener, in a case where the slider body 110 is mounted on an element (not shown) of the fastener chain, the decorative surface 122 of the decorative member 120 is exposed to the outside of the slide fastener, thereby providing a decorative purpose. The decoration application is, for example, to provide a specific pattern (for example, a trademark mark) on the decoration surface 122, or to provide a finger recess or the like when the slider 100 is a tab-less slider. As such, by the arrangement of the decoration member 120, a decoration or finger recess may be formed on the decoration surface 122 according to the requirement. The decorative member 120 is not simply a decorative layer formed on the slider body 110, but is formed on a projection 118 projecting outward from the upper plate 112 of the slider body 110, and particularly, the projection 118 having an umbrella-like design (or mushroom-like design) can be stably formed thereon. Also, the decorative member 120 may have a specific shape according to the requirement, so that a corresponding required finger recess (e.g., having a specific shape or size (e.g., length/width)) can be provided accordingly. As such, the slider 100 of the present embodiment can diversify the design and have good stability as compared with the related art.

Fig. 5 is a perspective explanatory view of the slider body of fig. 1. Fig. 6 is a top explanatory view of the slider body of fig. 5. Referring to fig. 5 and 6, in this embodiment, the slider body 110 further includes wings 119 projecting from the upper plate 112 and located on opposite sides of the projection 118. Further, the fin 119 is provided as a pair of ribs on opposite sides of the protrusion 118, and the fin 119 protrudes from the middle of the upper plate 112 in the longitudinal direction so as to cover the groove 118c (see fig. 4 and 5). The method of shielding the groove 118c is to set the height of the fin 119 to be equal to or greater than the height of the groove 118c (i.e., the thickness of the first portion 118a) so that the groove 118c is shielded by the fin 119 in the plane of the fin 119 (see fig. 4 and 5). The middle is not limited to the middle, but refers to a position closer to the middle than the opposite ends of the upper plate 112 in the longitudinal direction, but the present invention does not limit the position of the fin 119. In addition, the fin 119 may be regarded as a first portion of the protrusion 118, and in this case, the length of the second portion 118b is longer than the length of the fin 119 as the first portion, and becomes umbrella-shaped. Further, the fin 119 need not be provided, but additional provision can provide further effects as described below.

In detail, when the slider body 110 is manufactured with a mold (not shown), a release portion of the mold corresponds to a middle position of the upper plate 112, and after the mold is released, burrs are generally generated on the upper plate 112 corresponding to the release portion of the mold. In techniques that do not employ the fins 119, the flash is typically generated within the trench 118c at a location corresponding to the middle. When the groove 118c having a complicated shape is formed by using the protrusion 118 having a specific shape, a complicated removal step such as putting a polishing tool into the product is important for burrs (simply referred to as internal burrs) in the groove 118 c. In contrast, the method of masking the groove 118c in this embodiment forms the fin 119 at an intermediate position, i.e., the fin 119 corresponds to the released portion of the mold, and the flash generated at the released portion of the mold is present on the profile of the fin 119 and not within the groove 118 c. Burrs on the profile can be removed by relatively simple methods, such as rubbing against each other. Thus, in the present embodiment, the fin 119 is provided to prevent the formation of internal burrs in the groove 118c, thereby eliminating the cumbersome removal of the internal burrs. That is, even if the slider body 110 having a complicated shape is manufactured using a mold having a complicated structure (for example, the groove 118c has a complicated shape by using the protrusion 118 having a specific shape), since there is no internal burr in the groove 118c, it is not necessary to perform a troublesome removing step for the groove 118 c. Thus, the manufacturing cost of the slider body 110 can be greatly reduced.

In addition, as shown in fig. 4, the top surface of the fin 119 is substantially parallel to the top surface of the upper plate 112, and the side surface of the fin 119 is substantially aligned with the side surface of the upper plate 112, so that the fin 119 has a top surface and a side surface perpendicular to each other, and thus the cross section of the fin 119 is substantially rectangular. However, in other embodiments, not shown, the cross-section of the fin 119 may be trapezoidal (i.e. the side of the fin 119 is not aligned with the side of the upper plate 112 and is inclined with respect to the side of the upper plate 112), or other designs may be used. The shape of the fin 119 can be adjusted as desired. In addition, the decorative member 120 injection-molded around the protrusion 118 also covers the fin 119, so the height of the fin 119 is preferably less than or equal to the height of the protrusion 118 (for example, as shown in fig. 4, the height of the fin 119 is less than the height of the protrusion 118), but the size (for example, length/width) of the fin 119 may be adjusted according to the requirement. The shape and size of the fin 119 are not limited by the present invention as long as the fin 119 is disposed at the middle position of the upper plate 112 in a manner of shielding the groove 118c so as to prevent internal burrs from being generated in the groove 118 c.

As described above, the slider according to the present invention is formed by injection molding the decorative member on the slider body, and particularly, the decorative member is injection molded on the protruding portion protruding from the upper plate of the slider body, and the decorative surface can be decorated (for example, a specific pattern or a finger recess) as required. Compared with the prior art that the decorative layer or the finger recess is formed on the surface of the slider, the decorative part is further formed on the protruding part protruding outwards from the upper plate of the slider body, so that the decorative part can be stably formed on the protruding part to prevent the decorative part from falling off, and the decorative part can have a specific shape according to requirements and form a required pattern or the finger recess on the decorative surface. In addition, in order to improve the situation that the inner burr is generated when the slider body is formed by the mold, the invention provides the wing part corresponding to the middle position of the upper plate on the slider body, so that the burr is formed on the wing part instead of in the groove, thereby omitting the complicated removing step for the groove with the complex shape. Thus, the slider of the present invention can diversify the design and has good stability, and can reduce the manufacturing cost.
