Description

Slider

The invention relates to a slider.

The common zipper usually includes a pair of zipper chains composed of a zipper tape and a fastener element, and a slider installed on the zipper chain to open or close the fastener element by sliding, and a slider can also be provided on the slider according to requirements. Therefore, the user can drive the slider to slide on the zipper chain by pulling the pull tab. When a clothing manufacturer applies a zipper to a fabric (such as a coat), the clothing manufacturer usually sets its unique decorative pattern (such as a trademark pattern) on the pull tab, which can improve the brand recognition of the fabric sold. Of course, the manufacturer of the zipper also sets its own trademark design on the pull tab.

However, in the prior art of zippers, there are also zippers that do not use pull tabs (ie, no pull tab type zippers). The zipperless zipper includes a pair of zipper chains and sliders but does not have a zipper. Without the use of pull tabs, it is more difficult for the manufacturer of the zipper to design the decorative patterns required by the apparel manufacturer in the non-tab type zipper according to the needs of the apparel manufacturers. In this regard, Patent Documents 1 and 2 in the prior art documents propose a technical solution of providing a decorative material (such as a viscous material or colored paint) on the surface of the slider as a decorative layer. In addition, without using the slider, a finger grip can be provided on the surface of the slider, so that the user can push the finger grip with the finger to drive the slider to slide relative to the zipper chain. In response to this, Patent Document 3 in the prior art literature proposes a technical solution of providing a finger grip on the surface of the slider. [Prior Art Literature] [Patent Literature]

[Patent Literature 1] China Patent Publication No. CN107440261A [Patent Literature 2] Japanese Utility Model Publication No. JPS61-204506 [Patent Literature 3] China Design Bulletin No. CN304403830S

[Problems to be Solved by the Invention] As can be seen from the above, when a decorative pattern is provided on the slider-less zipper, usually a decorative material (such as a viscous material or colored paint) is provided as a decorative layer on the surface of the slider ( Such as Patent Documents 1 and 2). At this time, in order to enable the decorative layer to be smoothly formed on the surface of the slider, a recessed portion is usually provided on the surface of the slider, so that the decorative material can be fixed to the surface of the slider by filling the recessed portion. However, the recessed portion is limited by the size of the slider (for example, the thickness of the slider), especially the thickness of the upper plate of the slider, and is usually only slightly recessed inward. In this way, the bonding between the decorative layer formed by the recessed portion and the recessed portion is not high, so that the decorative layer is easily detached from the recessed portion. Furthermore, in the technical solution of providing a finger grip on the surface of the slider (as in Patent Document 3), the finger grip also has the above-mentioned problem of being limited to the size of the slider (such as the thickness of the slider), which makes the finger grip The design and operation of the Department are limited.

[Technical Means for Solving the Problems] The present invention provides a slider, which is a slider for a slide fastener, and includes a slider body and a decorative 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 decorative member is injection molded around the protrusion and has a decorative surface.

In an embodiment of the 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 invention, the thickness of the decorative component is smaller than the thickness of the slider body.

In an embodiment of the invention, the slider body further includes a fin portion, protruding from the upper plate, and located on opposite sides of the protruding portion.

In an embodiment of the present invention, the fin portion protrudes from the middle in the longitudinal direction of the upper plate so as to shield the groove.

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

[Effect of the Invention] Based on the above, in the slider of the present invention, the decorative member is injection-molded on the slider body, in particular, the decorative member is injection-molded on the protruding portion protruding from the upper plate of the slider body, and the decorative member The decorative surface provided can be decorated according to requirements (for example, a decorative layer or a finger grip with a specific pattern). Compared with the conventional technique of forming a decorative layer or a finger grip on the surface of the slider, the present invention further forms a decorative component on a protrusion that protrudes outward from the upper plate of the slider body to increase its stability In order to prevent it from falling off, it can be set into a specific shape according to requirements, and then a desired decorative pattern or finger grip portion is formed on its decorative surface.

In this embodiment, the slider 100 includes a slider body 110 and a decorative component 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 suitable for a zipper (not shown). In particular, the slider of the present invention may be a slider suitable as a lower slider in a pair of sliders used for a double-end zipper.

Specifically, in the present embodiment, the slider 100 is generally composed of the slider body 110 and the decoration member 120, but it is not limited thereto. The following length/width refers to the size from one end of the part to the other end on the opposite side in the length direction/width direction of the virtual plane where the slider 100 is located (corresponding to the mark in the drawing) , But not limited to this, it can be adjusted according to demand. In the slider body 110, the upper plate 112 and the lower plate 114 are generally plate-shaped and are arranged parallel to and face each other. As an example, the length of the upper plate 112 is equal to the length of the lower plate 114 (such as the length L1 in FIG. 2) ), and the width of the upper plate 112 is equal to the width of the lower plate 114 (such as the width W1 of FIG. 4 ), but it is not limited thereto. In other embodiments not shown, the upper plate 112 and the lower plate 114 may also have different shapes. The connecting post 116 has a column shape and is connected between the upper plate 112 and the lower plate 114. Preferably, the size of the connecting post 116 (such as the length L2 of FIG. 2/the width W2 of FIG. 4) is smaller than the size of the upper plate 112 or the size of the lower plate 114 (such as the length L1/width W1 of FIG. 4), There is a space S between the upper plate 112 and the lower plate 114, but this is not a limitation. When the slider 100 is applied to a zipper chain (not shown) to form a zipper, the slider body 110 can be installed on an element (not shown) of the zipper chain so that the element penetrates between the upper plate 112 and the lower plate 114 Within the space S. In this way, the slider 100 can be opened or closed by sliding the slider body 110 on the zipper chain.

Furthermore, in this embodiment, the slider body 110 includes a protrusion 118 protruding from the upper plate 112. Furthermore, the protrusion 118 includes a first portion 118a protruding from the upper plate 112 and a second portion 118b extending outward from the first portion 118a. Preferably, the size of the second portion 118b (such as the length L3 of FIG. 2/the width W3 of FIG. 4) is larger than the size of the first portion 118a (such as the length L4 of FIG. 2/the width W4 of FIG. 4), for example, the first portion 118a presents The second portion 118b has a plate shape, and a groove 118c is formed between the second portion 118b, the upper plate 112, and the side of the first portion 118a. As such, the protrusion 118 does not present a uniform length or width, but the size of the upper side (ie, the second portion 118b) (such as the length L3 of FIG. 2/the width W3 of FIG. 4) is greater than the size of the lower side (ie, the first portion 118a) (Length L4 of FIG. 2 / width W4 of FIG. 4 ), so that the protrusion 118 takes the shape of an umbrella, or a mushroom. In this way, the above-mentioned design contributes to the arrangement of the decorative component 120 (as described later).

In detail, the decorative member 120 is injection molded from a rubber material (for example, natural rubber, synthetic rubber, urethane rubber, fluororubber, various elastomers, silicon, but not limited thereto) around the protrusion 118 and has a decorative surface 122. More specifically, the decoration member 120 is injection-molded from the upper side of the protrusion 118 (ie, the second portion 118 b) toward the upper plate 112, and is located on the upper plate 112. Preferably, the decoration member 120 covers the entire protrusion 118, that is, the decoration 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 this embodiment is umbrella-shaped (or mushroom-shaped), that is, the size of the second portion 118b (such as the length L3 of FIG. 2/the width W3 of FIG. 4) is larger than the size of the first portion 118a (as shown in FIG. 2 length L4 / width W4 of FIG. 4), and a groove 118c is formed between the second portion 118b, the upper plate 112 and the side of the first portion 118a, so when the decorative member 120 is injection molded around the protrusion 118 The decoration member 120 covers the first portion 118a and the second portion 118b of the protrusion 118 and fills the groove 118c, and preferably further contacts the surface of the upper plate 112 facing the groove 118c. In this way, the decorative member 120 can interfere with the protrusion 118 having an umbrella-shaped design (or mushroom shape), and can be stably formed on the protrusion 118. That is, the protrusion 118 contributes to the installation of the decorative member 120. However, in other embodiments not shown, the protruding portion may be other embodiments (such as using a convex column with a uniform length or a uniform width), and the present invention is not limited thereto. As long as the slider body 110 has a protruding portion protruding from the upper plate 112, it can contribute to the installation of the decorative member 120.

In addition, in this embodiment, the size of the protrusion 118 (such as the length L3 or L4 of FIG. 2 / the width W3 or W4 of FIG. 4) is smaller than the size of the upper plate 112 (such as the length L1 of FIG. 2 / the width W1 of FIG. 4) ). In the case where the decorative member 120 is injection-molded on the protrusion 118, the decorative member 120 contacts the surface of the upper plate 112 facing the groove 118c, and the size of the decorative member 120 (such as the length L5 of FIG. 2/the width W5 of FIG. 4) is smaller than or It is equal to the size of the upper plate 112 (length L1 in FIG. 2 / width W1 in FIG. 4). In this way, the decoration member 120 and the slider body 110 have similar outer contours. Preferably, the decoration member 120 covers the entire 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 a beautiful appearance. However, in other embodiments not shown, the decorative component 120 can cover only a part of the protrusion 118 (ie, the size of the decorative component 120 (eg, length/width) is smaller than the size of the protrusion 118 (eg, length/width)) or It extends to the outside of the protrusion 118 (that is, the size (such as length/width) of the decorative member 120 is larger than the size (such as length/width) of the protrusion 118 ), or further covers the side of the upper plate 112.

In addition, in this embodiment, the thickness d1 of the decoration member 120 is greater than the thickness d2 of the protrusion 118, but smaller than the thickness d3 of the connecting post 116 (ie, the distance between the upper plate 112 and the lower plate 114/the height of the space S), Or less than the overall thickness of the slider body 110 (ie, the sum of the thicknesses d2 and d3). However, in other embodiments not shown, the thickness d1 of the decoration component 120 may be adjusted to be smaller than the thickness d2 of the protrusion 118 (for example, the decoration component 120 only covers the second portion 118b without filling the groove 118c), or The thickness d1 of the decoration member 120 is adjusted to be greater than the thickness d3 of the connecting post 116 (ie, the distance between the upper plate 112 and the lower plate 114/the height of the space S) or even greater than the overall thickness of the slider body 110 (ie, the thickness d2 and d3 sum). Alternatively, the thickness d1 of the decorative member 120 may be adjusted to a non-uniform thickness, or the decorative member 120 may have a specific shape. As long as the design of the decorative component 120 does not interfere with the sliding of the slider body 110 on the zipper chain, the present invention does not limit the specific shape of the decorative component 120, which can be adjusted according to requirements.

Furthermore, the decorative component 120 has a decorative surface 122 which refers to the outer surface of the decorative component 120 opposite to the slider body 110. When the slider 100 is applied to a zipper chain (not shown) to form a zipper, when the slider body 110 is mounted on the fastener element (not shown) of the zipper chain, the decorative surface 122 of the decorative member 120 is exposed to the zipper It can be used for decorative purposes. The decorative purpose is, for example, to provide a specific pattern (such as a trademark pattern) on the decorative surface 122, or to provide a finger grip when the slider 100 is without a pull tab. In this way, with the arrangement of the decoration member 120, decoration or finger grips can be formed on the decoration surface 122 according to requirements. The decorative component 120 is not simply a decorative layer formed on the slider body 110, but is further formed on a protrusion 118 protruding outward from the upper plate 112 of the slider body 110, especially having an umbrella-shaped design (or mushroom The shape of the protrusion 118 can be stably formed thereon. In addition, the decorative component 120 may have a specific shape according to needs, so the finger grip portion (eg, having a specific shape or size (eg, length/width)) corresponding to the desired portion can be set accordingly. In this way, the slider 100 of this embodiment can diversify the design and have good stability compared to the conventional technology.

5 is a schematic perspective view of the slider body of FIG. 1. 6 is a schematic plan view of the slider body of FIG. 5. Please refer to FIGS. 5 and 6. In this embodiment, the slider body 110 further includes a fin portion 119 protruding from the upper plate 112 and located on opposite sides of the protrusion 118. More specifically, the fins 119 are distributed on the opposite sides of the protrusion 118 in the form of a pair of ribs, and the fins 119 cover the groove 118c (as shown in FIGS. 4 and 5) from the upper plate 112. Protruding in the middle of the length direction. The way of shielding the groove 118c refers to setting the height of the fin 119 above the height of the groove 118c (ie, the thickness of the first portion 118a), so that the groove 118c is shielded by the fin 119 in the plane where the fin 119 is located (as shown in FIG. 4 and Figure 5). In addition, 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 portion 119 may also be regarded as the first portion of the protruding portion 118. In this case, the length of the second portion 118b is larger than the length of the fin portion 119 as the first portion and becomes umbrella-shaped. In addition, if the fin portion 119 is not required, it may not need to be provided in particular. However, the additional effect can be expected as described below.

In detail, when the slider body 110 is manufactured by a mold (not shown), the detached portion of the mold corresponds to the middle position of the upper plate 112, and after the mold is detached, it usually corresponds to the mold on the upper plate 112 The burrs are generated at the part of the detachment. In a technique that does not use the fin portion 119, the burr is usually generated in the groove 118c at a position corresponding to the middle position. In the case where a groove 118c having a complicated shape is formed by using a protrusion 118 of a specific shape, it is important for the burrs generated in the groove 118c (abbreviated as internal burrs) to be a cumbersome removal step such as putting a grinding tool inside the product . In contrast, in this embodiment, the fin 119 is formed in the middle position in a manner of shielding the groove 118c, that is, the fin 119 corresponds to the detached portion of the mold, so that the burrs generated at the detached portion of the mold exist in the fin 119. The outline does not exist in the groove 118c. The burrs on the contour can be removed by relatively simple methods such as rubbing against each other. In this way, in this embodiment, by providing the fins 119, it is possible to avoid the generation of internal burrs in the groove 118c, and it is possible to omit the cumbersome removal step of the internal burrs. That is, even if a complex-structured mold is used to manufacture the slider body 110 having a complicated shape (eg, the protrusion 118 of a specific shape is used to make the groove 118c have a complicated shape), since there is no internal burr in the groove 118c, there is no need to align the groove 118c uses cumbersome removal steps. In this way, 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 portion 119 is substantially parallel to the top surface of the upper plate 112, and the side surface of the fin portion 119 is substantially aligned with the side surface of the upper plate 112, so the fin portions 119 have each other The vertical top surface and side surface, and accordingly the cross section of the fin portion 119 is substantially rectangular. However, in other embodiments not shown, the cross section of the fin 119 may also be trapezoidal (that is, the side of the fin 119 is not aligned with the side of the upper plate 112 and is relative to the side of the upper plate 112 Present oblique), or adopt other designs. The shape of the fin 119 can be adjusted according to needs. In addition, the decoration member 120 injected 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 (as shown in FIG. 4 is the fin 119 Is smaller than the height of the protrusion 118), but the size (such as length/width) of the fin 119 can also be adjusted according to requirements. The shape and size of the fin 119 are not limited as long as the fin 119 is provided in the middle of the upper plate 112 in the form of a shielding groove 118c to avoid the generation of internal burrs in the groove 118c.

In summary, the slider of the present invention has injection molding parts formed on the slider body, and in particular, the injection molding parts are formed on the protrusions protruding from the upper plate of the slider body, and the decorative surface can be decorated according to requirements ( For example, specific patterns or finger grips). Compared with the conventional technique of forming a decorative layer or a finger grip on the surface of the slider, the present invention further forms a decorative member on a protruding portion that protrudes outward from the upper plate of the slider body, and can be stably formed on It can prevent it from falling off, and can have a specific shape according to needs, and form a desired decorative pattern or finger grip on its decorative surface. In addition, in order to improve the occurrence of internal burrs when the slider body is formed by a mold, the present invention provides fins corresponding to the middle position of the upper plate on the slider body, so that the burrs are formed on the fins rather than in the grooves To omit the cumbersome removal steps for trenches with complex shapes. In this way, the slider of the present invention can diversify the design and have good stability, and can reduce the manufacturing cost.
