Description of the Invention: [Technical Field] The present invention relates to a slider cover for covering at least portions of a slider body of a slider. [Prior Art] The slider is usually composed of a slider body and a pull tab. Many slider bodies are made of metal and are therefore often overheated or too cold, and particularly in hot or cold climates' may cause discomfort when in contact with the user's skin. At extreme temperatures, metal slides can even cause frostbite or minor burns. A slider cover made of a thermally insulating material, such as plastic, helps protect the user's skin from damage from certain parts of the slider when the slider is in certain positions. However, conventional slider covers have several limitations. For example, conventional slider covers do not cover the top and/or front of the slider body, and when the top and/or front of the slider body is in contact with the user's skin When exposed, it may still cause discomfort. SUMMARY OF THE INVENTION The present invention discloses a slider assembly that is configured to cover and/or prevent contact between a user's lower jaw and a front portion of the slider body. In some versions, the slider is always The invention comprises: (1) a slider body comprising an upper wing and a lower wing, wherein the upper wing and the lower wing are spaced apart from each other and joined by a connecting neck, wherein the lower wing comprises a leading edge, the leading edge a front portion of the slider body; and (2) a slider cover including a body and a leading edge, wherein the slider cover is positioned relative to the lower wing of the slider body such that the body of the slider cover covers 163314 .doc 201242537 At least part of the underside of the lower wing, the leading edge of the lower wing. In some versions into. And the front edge of the slider cover extends forwardly beyond, and the slider cover is made of a thermally insulating material. The applicant does not wish to be bound by the foregoing or any other understanding of the manner in which the invention or any prior art works. [Embodiment] The complete license disclosure is set forth in more detail in the remainder of the specification, including the best mode of practicing the scope of the appended claims, and is generally known to those skilled in the art. The present specification refers to the following drawings in which the same reference numerals are used in the different figures to illustrate the same or similar components. The present invention discloses an improved slider cover for use with a slider body of a slider. Circles 1 through 25 show the slider cover 1 〇, and Figs. 26 through 41 show the slider cover 110. The slider cover 10 or 110 is positioned relative to the slider body (such as the slider body 20 shown in FIGS. 9-13 or the slider body 2〇 shown in FIGS. 16-20) to cover the slider body At least a portion and protecting the user from contact with the slider body. The slider assembly 8 relates to a slider cover 1 定位 positioned relative to the slider body, and the slider assembly 108 relates to a slider cover 110 positioned relative to the slider body. The curtain is well known. The sliding fastener includes a left and right chain a cloth and sprocket attached to opposite side edge portions of the key cloth. The slider cooperates with the sprocket (such as the sprocket 52 shown in Figures 5-8) located on the chain cloth (such as the chain cloth 5 shown in Figures 5-8) to open and close the zipper. The slider typically includes a slider body (such as slider body 20) and a pull tab (not shown) that is attached to the slider body in a known manner as I63314.doc 201242537. When the tab is moved in one direction, a generally Y-shaped channel (such as guide channel 42) between the upper wing of the body (such as the upper wing 3()) and the lower wing (such as the lower wing 32) will be chained. The opposite rows of the cloth are reviled. When the tab moves in the opposite direction, the generally Y-shaped channel separates the rows of opposed sprocket. When the slider assembly 8 is at one of its longitudinal ends of the sliding fastener, the slider assembly 8 is typically in contact with the skin of the user (such as as shown in Figures 14-15). Contact) location. In particular, the front portion 28 and/or the top portion 2 of the slider assembly 8 are positioned relative to the user's lower jaw. The slider assembly 8 includes a slider body 20 and a slider cover 10 as shown, for example, in Figs. 16 to 25. When positioned as shown in Figures 14 through 15, the slider body 20 will be in direct contact with the lower jaw if there is no slider cover 10'. As shown in FIGS. 9 to 13, the slider body 2 has a top portion, a bottom portion 24, a front portion 28, a rear portion 26, and left and right side surfaces 51. The front side of the slider body 2 意 means the upper side with respect to the plane of the paper of Fig. 11. The rear side of the slider body 2 意 means the lower side with respect to the plane of the paper of Fig. 11. The left side of the slider body 20 means the left side with respect to the plane of the paper of Fig. 11. The right side of the slider body 20 means the right side with respect to the plane of the paper of Fig. i i . The upper side of the slider body 20 means the proximal side of the plane of the paper relative to the figure. The lower side of the slider body 20 means the far side with respect to the plane of the paper. Hereinafter, the front, rear, left side, right side, upper side, and lower side are defined according to the plane of the paper of Fig. 11 unless otherwise defined. The slider body 20 includes an upper wing 30 and a lower wing 32 that are spaced apart from one another and joined at the front portion 28 by a connecting neck 46 (sometimes referred to as a diamond) to form a generally Y-shaped Guide channel 42. The upper wing 30 and the lower wing 32 are tapered to gradually reduce the width dimension in the left and right direction toward the rear portion 26 toward 163314.doc 201242537. The column extends from the top 22 of the upper wing 30 of the slider body 20, and a tab can be pivotally received around the column 34. From top to bottom view (i.e., in a top plan view of the slider body 20), the slider body 2 can have a conventional configuration such that the upper and lower wings have substantially similar shapes and sizes (see Figure 16). Up to FIG. 20), or as shown in FIGS. 9-13 and 21-25, the slider body can have a lower wing 32 and an enlarged flange 48. The enlarged flange 48 can be a separate piece that is attached to the bottom 24 of the lower wing 32 (as shown in Figures 11-13) or can be integrally formed as part of the lower wing 32. 1 to 8 and Figs. 14 to 25 show the slider cover 1''. The slider cover 1 is comprised of a body 11 which may be formed from any suitable thermally insulating material such as plastic (such as nylon, polyester, polypropylene, polyacetal, etc.), rubber, leather or other suitable relatively soft material. material. In some versions, the slider cover 1 is formed of a polyoxyl or polyurethane material. If formed of polyfluorene, the poly-stone material may have a hardness of between about 25 and about 1 Torr according to ASTM D2240 Type A scale (sh〇re dur) 〇meter hardness)' and the thermal conductivity between about ο.? and about 3 watts/meter. absolute temperature (W/(m*K)). If formed from a polyurethane, the polyurethane material according to ASTM D2240 Type A hardness tester may have a Shore hardness of between about 20 and about 95, and between about 〇. Thermal conductivity between 037 and about 0. 332 watts/meter. Absolute temperature (W/(m*K). Further, according to ASTM D2240 Type D hardness tester, the polyurethane material may have between about 30 Shore hardness between about 90 and 90. As mentioned above, the slider cover is configured to cooperate with the slider body 2 to make the slider cover 10 and the lower wing of 163314.doc -6· 201242537 32. In particular, the slider cover 1 is clamped relative to the slider body 20 such that contact between the user's skin and the slider body is limited by the slider cover 10. In some versions, the slider cover 1 〇 preventing contact with the connecting neck 46 of the slider body. For example, as shown in FIGS. i to 8 and FIGS. 14 to 25, the body of the slider cover 1 covers the entire surface of the bottom portion 24 of the lower wing 32. The cover of the body 11 to the bottom 24 of the lower wing 32 is not limited to the example shown in the figures. For example, the body 丨丨 can cover the bottom portion 24 of the lower wing 32 in the slider At least a portion of the front portion 28 of the front portion 28. That is, the bottom cymbal 24 of the lower wing 32 may not be covered at the side of the rear portion 26 of the slider body 2〇. The slider cover j 〇 the leading edge 14 extends forward beyond The leading edge 44 of the lower wing 32. The leading edge 44 is along the edge of the front portion 28 of the slider body 20. At the center 53 of the leading edge 44 in the left and right direction of the slider body 2, the slider cover 1 〇 extends forward Beyond the leading edge 44 dimension Y (see Figures 16 and 18). In this manner, the slider cover 1 〇 the leading edge 14 protrudes 'to limit the user's connection with the slider body 46 and/or the slider body Contact between the top portions 22. Relative to the front portion of the slider assembly, the amount of slider cover 延伸0 extending beyond the slider body is greater than the amount of other portions of the slider assembly extending beyond the slider body. For example, As shown in Fig. 18, the lateral edges 16 of the slider cover 1 extend left and right beyond the lateral edges 45 of the lower wings 32. The lateral edges 45 are along the edges of the left and right side faces 51 of the slider body 2's. Between point a 1 and point B1, the slider cover 10 extends forward beyond the specific point on the leading edge 44 of the slider body 20 by a greater amount than the slider The lateral edge 16 of the 10 extends left and right beyond the lateral edge 45 of the slider body 2', wherein the point A1 is located on one of the left and right directions of the slider body 20 at the front portion 28 of the slider body 2〇, Point b丨 passes through the connection 163314.doc 201242537 with respect to point a1. The interface 46 is located on the opposite side of the slider body in the left-right direction at the front portion 28 of the π-piece body 2. The slider cover 10 can be in any suitable manner. The slider body 2 is snapped. The slider cover 1 includes an optional recess 12 (Fig. 2) that is shaped and sized to receive the lower wing 32 of the slider body 20. The slider cover 10 can then be adhered to the lower wing 32 of the slider body 20 using any suitable glue or adhesive. The adhesion between the slider cover 1 〇 and the slider body 20 is not limited to the case of using glue or an adhesive. For example, a configuration in which the slider cover and the slider body are Snapped to each other can be used. Figures 16 to 20 show that the slider cover 1 〇 is adhered to the slider body 20 having a conventional configuration, wherein when viewed from above (i.e., in a top plan view of the slider body 20), the upper wing 3〇 is substantially the same shape and/or size as the lower wing 32, and wherein the bottom portion 24 of the lower wing 32 is received in the recess 12 of the slider cover 1〇. In other versions, the recess 12 is not required because the slider cover j is attached to the slider body 2 by injection molding. For example, the slider body 20 has a lower wing 32 and an enlarged flange 48 (FIG. 11) projecting from the periphery of the lower wing 32. The slider body 2 can include a plurality of peripherals 49 along the enlarged flange. Holes 4 are arranged at predetermined intervals. The hole 4 穿 penetrates the enlarged edge 48 in the up and down direction. The slider cover 1 is coupled to the lower wing 32 via an enlarged flange 48 using injection molding. In detail, the slider body 2 〇 lower wing 32 is introduced into the mold for forming the slider cover 10 to cause the liquid/melting material for forming the slider cover to flow into the hole 40, thereby After the material cools and solidifies, a stronger engagement is formed between the slider cover 10 and the slider body 20. Figure 24 is a cross-sectional view showing how the slider cover 10 is attached to the lower wing 32 by injection molding through the hole 4 163314.doc 201242537. Alternatively, the slider cover 10 can be coupled to the slider body 20 by a fitting method such as use with attaching a retractable cover to a mobile phone or an MP3 player. The slider cover 110 is illustrated in Figures 26 through 41. The slider cover 11 is similar to the slider cover 10 except that the slider cover 11 includes a protrusion U6 that extends substantially upward from the slider body 111. As shown, the projections 116 extend generally perpendicularly from the slider cover body lu, but the projections 116 can extend at other suitable angles. For example, as shown in Fig. 32, when the projection 116 is positioned relative to the slider body 2, the projection 116 covers the attachment neck 46 and thus prevents contact between the user's skin and the connecting neck. The protrusion 116 includes a dimension Z (Fig. 28) which is substantially equal to or larger than the size of the connecting neck 46 (Fig. 9) above and below the slider body 2〇. The 突起β projection 116 only needs to cover the side of the lower neck 32 of the connecting neck 46. At least one part of the office is. That is, the size ζ of the protrusion 116 may be smaller than the dimension X of the connecting neck 46. When the slider cover 110 is positioned relative to the slider body 20, a space is defined between the rear surface of the projection 116 and the front surface of the joint neck 46 in the front and rear direction of the slider body 2''. With this space, when the slider cover is attached to the slider body, the protrusion and the slider body do not interfere with each other. Therefore, the slider cover can be easily attached to the slider body. When the user's skin comes into contact with the projection 116, it is also possible to obtain a space for the projection 116 to be elastically deformed toward the connecting neck 46. Slider - The cover U〇 can be made of the same material as the slider cover 10. Similar to the slider cover 1 , the slider cover 110 can be attached to the conventional slider body or the slider body having the lower and enlarged flanges 48 using any suitable method. Numerous modifications of the invention can be made in the compositions, applications and manufacturing processes of the present invention, as well as in other aspects, without departing from the scope and spirit of the invention.
