Description

Technical Field

[0001] The present invention relates to a technology in the field of zippers, and particularly to a tab pull for a zipper. Background Art

[0002] A common zipper generally includes a fastener chain composed of a pair of fastener stringers each consisting of a strip-shaped fastener tape and a plurality of element columns arranged on the fastener tape, and a slider for the zipper installed on the fastener stringer to open or close the element columns by sliding, and a tab pull for the zipper can also be provided on the slider according to requirements.

[0003] In the prior art, a tab pull for a zipper generally includes a slider connection portion for being installed on the slider for the zipper, and a pinching portion for a user to pinch with fingers to operate the tab pull for the zipper. Among them, a cord can be used as the slider connection portion of the tab pull for the zipper, and a pinching portion formed of a resin material is provided at the end of the cord by injection molding, so that the cord can be used to install the tab pull for the zipper on the slider for the zipper through the tab pull installation portion of the slider for the zipper, and the slider for the zipper is driven to slide through the pinching portion at the end of the cord.

[0004] However, such a tab pull for a zipper needs to be made of different materials (i.e., the cord serving as the slider connection portion, the resin material for forming the pinching portion, etc.), resulting in an increase in the required processes and manufacturing costs. In addition, if the structure of the tab pull for the zipper is improved to reduce the manufacturing processes, it is also necessary to consider the structural strength and operability of the improved tab pull for the zipper. Summary of the Invention

[0005] The present invention provides a tab pull for a zipper, which can reduce the manufacturing processes to lower the manufacturing cost, and has sufficient structural strength and good operability.

[0006] The present invention provides a tab pull for a zipper, which is suitable for being installed on a slider for a zipper, and includes: a pinching portion configured as a sheet; a slider connection portion extending outward from the front end of the pinching portion and adapted to pass through the tab pull installation portion of the slider for the zipper; a fitting portion located on one side surface of the pinching portion in the width direction; and a fitting portion extending outward from the end of the slider connection portion, and the fitting portion is fitted into the fitting portion along the side surface of the pinching portion to close the slider connection portion to form a ring.

[0007] In an embodiment of the present invention, the part to be fitted includes an extending recess extending along the side surface of the pinching part, and a fitting recess located at the end of the extending recess. The fitting part includes an extending rod part extending along the side surface of the pinching part from the end of the slider connecting part, and a fitting protrusion located at the end of the extending rod part. Wherein the extending rod part is fitted into the extending recess along the side surface of the pinching part, and the fitting protrusion is fitted into the fitting recess, so that the fitting part is fitted to the part to be fitted.

[0008] In an embodiment of the present invention, the extending recess extends along the side surface of the pinching part from the front end of the pinching part to the rear end of the pinching part, and the fitting recess is located at the rear end of the pinching part.

[0009] In an embodiment of the present invention, the extending direction of the extending recess intersects with the extending direction of the fitting recess, and the extending direction of the extending rod part intersects with the extending direction of the fitting protrusion.

[0010] In an embodiment of the present invention, the part to be fitted further includes a rotating recess located at the end of the fitting recess, and the fitting part further includes a bent convex part located at the end of the fitting protrusion. Wherein the extending direction of the rotating recess intersects with the extending direction of the fitting recess to form a hook shape at the end of the part to be fitted, the extending direction of the bent convex part intersects with the extending direction of the fitting protrusion to form a hook shape at the end of the fitting part, and the bent convex part is fitted into the rotating recess, so that the fitting part is fitted to the part to be fitted.

[0011] In an embodiment of the present invention, the slider connecting part extends from the first side in the width direction to the second side opposite to the first side at the front end of the pinching part, and the part to be fitted is located on the side surface of the pinching part corresponding to the second side.

[0012] In an embodiment of the present invention, a recess is formed on the outer surface of the pinching part near the first side, and in the perspective view from the front of the pinching part, the recess does not overlap with the area corresponding to the part to be fitted on the pinching part.

[0013] In an embodiment of the present invention, the pinching part, the slider connecting part, and the fitting part are made of a soft material.

[0014] In an embodiment of the present invention, the shape and size of the fitting part correspond to the shape and size of the part to be fitted, so that the fitting part is fitted to the part to be fitted to form a tight fit.

[0015] In an embodiment of the present invention, the pinching portion, the slider connecting portion, the engaging portion, and the engaged portion are different parts of a single integrally formed member.

[0016] Based on the above, in the slider for a zipper of the present invention, the slider connecting portion extends outward from the front end of the pinching portion, the engaged portion is on one side surface of the pinching portion in the width direction, the engaging portion extends outward from the end of the slider connecting portion, wherein the slider connecting portion is adapted to pass through the slider mounting portion of the slider for a zipper, and the engaging portion is fitted into the engaged portion along the side surface of the pinching portion, so that the slider connecting portion is closed to form a ring. In this way, the slider for a zipper can be made of the same material, and can be installed and fixed by the cooperation of its own structure (i.e., the engaged portion and the engaging portion), and thus can be easily installed on the slider by opening or closing. In particular, the engaging portion is fitted into the engaged portion along the side surface of the pinching portion, which can make the engaging portion and the engaged portion have a good connection effect, so that the slider for a zipper in the closed state is not easily loosened during use.

[0052] Reference will now be made in detail to exemplary embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Among them, Figure 1 is a perspective view of a slider for a zipper in a closed state according to an embodiment of the present invention, Figure 2 is Figure 1 a front view of the slider for a zipper shown in Figure 3 in a closed state, Figure 1 a top view of the slider for a zipper shown in Figure 4 in a closed state, Figure 1 a side view of the slider for a zipper shown in Figure 5 in an open state, Figure 1 is a perspective view of the process of installing the slider for a zipper shown in Figure 6 on a slider for a zipper, Figure 5 a perspective view of the slider for a zipper shown in Figure 7 after being installed on a slider for a zipper. The following will be described in conjunction with Figures 1 to 7 the specific structures of the slider 100 for a zipper and its variations in an embodiment of the present invention, as well as the installation means when it is applied to the slider 50 for a zipper, etc. However, the present invention is not limited thereto and can be adjusted according to requirements.

[0053] Please refer to Figures 1 to 6 , in this embodiment, the slider 100 for a zipper is adapted to be installed on the slider 50 for a zipper, and includes a pinch portion 110, a slider connection portion 120, an engaged portion 130, and an engaging portion 140. The pinch portion 110 is configured as a sheet for a user to pinch with fingers to operate the slider 100 for a zipper. The slider connection portion 120 extends outward from the front end E1 of the pinch portion 110 and is adapted to pass through the slider mounting portion 52 of the slider 50 for a zipper (as shown in Figure 5 and Figure 6 ). The engaged portion 130 is located on one side surface 112 of the pinch portion 110 in the width direction W. The engaging portion 140 extends outward from the end portion 120a of the slider connection portion 120, and the engaging portion 140 is engaged along the side surface 112 of the pinch portion 110 into the engaged portion 130, so that the slider connection portion 120 is closed to form a ring.

[0054] Specifically, in the present embodiment, the pinching portion 110 is, for example, a substantially long strip-shaped structure extending in the front-rear direction (i.e., the length direction L), but it can also be set to the required shape according to requirements, and its dimensions (length, width, thickness) can be adjusted according to requirements, and the present invention is not limited thereto. Correspondingly, the slider connecting portion 120 is an elongated strip-shaped structure extending outward from the front end E1 of the pinching portion 110, so that it can pass through the mounting hole 52a on the tab mounting portion 52 of the slider 50 for the zipper. Preferably, the dimension of the slider connecting portion 120 in the width direction W is smaller than the dimension of the pinching portion 110 in the width direction W. That is, relative to the pinching portion 110 configured as a sheet, the slider connecting portion 120 is configured as a long strip. In this way, the slider connecting portion 120 can be bent without a too long length, and can easily wrap around the side surface 112 of the pinching portion 110 after passing through the tab mounting portion 52 of the slider 50 for the zipper to form a loop. However, as long as the slider connecting portion 120 can be installed through the tab mounting portion 52, its dimensions (length, width, thickness) can be adjusted according to requirements, and the present invention is not limited thereto.

[0055] Furthermore, in the present embodiment, the engaged portion 130 and the engaging portion 140 are respectively provided on the pinching portion 110 and the slider connecting portion 120. Among them, the engaged portion 130 is, for example, a recessed structure formed on the side surface 112 of the pinching portion 110, and the engaging portion 140 is, for example, a protruding structure formed on the end portion 120a of the slider connecting portion 120 opposite to the pinching portion 110. That is to say, one end of the slider connecting portion 120 is connected to the front end E1 of the pinching portion 110, and the engaging portion 140 is formed at the other end of the slider connecting portion 120, so that the slider connecting portion 120 can be connected to the side surface 112 of the pinching portion 110 through the engagement of the engaging portion 140 and the engaged portion 130, and the slider connecting portion 120 is closed to form a loop. In this way, when the engaging portion 140 moves into the engaged portion 130 in the direction approaching the pinching portion 110 (as Figure 1 shown), the zipper tab 100 is in the closed state (the slider connecting portion 120 is closed to form a loop), and when the engaging portion 140 moves out of the engaged portion 130 in the direction away from the pinching portion 110 (as Figure 2 shown), the zipper tab 100 is in the open state. Figure 4 shown), the zipper tab 100 is in the open state.

[0056] It can be seen from this that when the zipper tab 100 is in the open state, as Figure 4 shown and Figure 5As shown, since the fitting portion 140 formed by the end portion 120a of the slider connecting portion 120 is separated from the fitted portion 130, the slider tab 100 for the zipper can pass through the mounting hole 52a of the tab mounting portion 52 of the slider 50 for the zipper with the end portion 120a of the slider connecting portion 120 together with the fitting portion 140. After the slider connecting portion 120 passes through the tab mounting portion 52, as Figure 6 shown, the fitting portion 140 formed by the end portion 120a of the slider connecting portion 120 can be fitted to the fitted portion 130 to close the slider connecting portion 120 to form a ring. In this way, the slider tab 100 for the zipper can be made of the same material, and can be installed and fixed by the cooperation of its own structure (that is, the fitted portion 130 and the fitting portion 140), so that it can be easily installed on the slider 50 for the zipper by opening or closing. In particular, the fitting portion 140 is fitted to the fitted portion 130 along the side surface 112 of the pinching portion 110, so that the fitting portion 140 and the fitted portion 130 can have a good connection effect, and the slider tab 100 for the zipper in the closed state is not easily loosened during use. Accordingly, the slider tab 100 for the zipper can reduce the manufacturing process to reduce the manufacturing cost, and has sufficient structural strength and good operability.

[0057] As an example, in the present embodiment, as Figures 1 to 4As shown, the engaged portion 130 includes an extending recess 132 extending along the side surface 112 of the pinching portion 110 and an engaging recess 134 located at the end of the extending recess 132. Correspondingly, the engaging portion 140 includes an extending rod portion 142 extending along the side surface 112 of the pinching portion 110 from the end portion 120a of the slider connecting portion 120 and an engaging protrusion 144 located at the end of the extending rod portion 142. Among them, the extending rod portion 142 is engaged into the extending recess 132 along the side surface 112 of the pinching portion 110, and the engaging protrusion 144 is engaged into the engaging recess 134, so that the engaging portion 140 is engaged with the engaged portion 130. Preferably, the extending recess 132 extends from the front end E1 of the pinching portion 110 to the rear end E2 of the pinching portion 110 along the side surface 112 of the pinching portion 110, and the engaging recess 134 is located at the rear end E2 of the pinching portion 110. That is, the extending recess 132 is, for example, a long groove formed in the side surface 112 of the pinching portion 110 and communicating with the front end E1 and the rear end E2, and the engaging recess 134 is a transverse notch at the end of the long groove. In contrast, the extending rod portion 142 is also provided as a long rod portion extending from the front end E1 to the rear end E2 corresponding to the length of the extending recess 132, and the engaging protrusion 144 is a transverse protrusion at the end of the long rod portion. Moreover, the extending direction of the extending recess 132 (substantially corresponding to the length direction L of the side surface 112 of the pinching portion 110) intersects with the extending direction of the engaging recess 134 (substantially corresponding to the width direction W) to form a substantially L shape, and the extending direction of the extending rod portion 142 intersects with the extending direction of the engaging protrusion 144 to form a substantially L shape.

[0058] With the above settings, in this embodiment, the extended recess 132 of the engaged portion 130 is formed on the side surface 112 of the pinching portion 110 so as to span the front end E1 and the rear end E2 in the front-rear direction (i.e., the length direction L), and further opens outward at the front end E1, the side surface 112, and the rear end E2. Thus, the extended rod portion 142 of the engaging portion 140 is engaged in the extended recess 132 of the engaged portion 130 formed on the side surface 112 of the pinching portion 110 so as to span the front end E1 and the rear end E2 in the front-rear direction (i.e., the length direction L), thereby increasing the contact area between the engaging portion 140 and the engaged portion 130 that are engaged with each other, and improving the structural strength of the slider tab 100 for a zipper. In particular, during the process in which the engaging portion 140 moves into the engaged portion 130 in a direction approaching the side surface 112, the extended rod portion 142 can enter the extended recess 132 from the opening at the front end E1 of the extended recess 132, and the engaging protrusion 144 can enter the engaging recess 134 from the opening at the rear end E2 of the extended recess 132 (i.e., the end of the extended recess 132), so that the engaging portion 140 can be easily engaged with the engaged portion 130. Furthermore, the engaging protrusion 144 of the engaging portion 140 is engaged with the engaging recess 134 of the engaged portion 130 along the width direction W, so that the engaging protrusion 144 can interfere with the inner wall surface of the engaging recess 134 in the front-rear direction (i.e., the length direction L). Thus, when the slider tab 100 for a zipper is mounted on the tab mounting portion 52 of the slider 50 for a zipper, even if the user pinches the pinching portion 110 of the slider tab 100 for a zipper and operates the slider tab 100 for a zipper in the front-rear direction (i.e., the length direction L), the engaging portion 140 is not easily detached from the engaged portion 130. Accordingly, the slider tab 100 in the closed state is not easily loosened during use, and has sufficient structural strength and good operability.

[0059] Furthermore, in the present embodiment, the fitting part 130 further includes a rotary recess 136 located at the end of the fitting recess 134, and the fitting part 140 further includes a bent convex part 146 located at the end of the fitting protrusion 144. Among them, the extending direction of the rotary recess 136 (substantially corresponding to the length direction L) intersects with the extending direction of the fitting recess 134 (substantially corresponding to the width direction W), so that the end of the fitting part 130 forms a hook shape. Correspondingly, the extending direction of the bent convex part 146 intersects with the extending direction of the fitting protrusion 144, so that the end of the fitting part 140 forms a hook shape. Thus, when the extending rod part 142 is fitted into the extending recess 132 along the side surface 112 of the pinching part 110 and the fitting protrusion 144 is fitted into the fitting recess 134, the bent convex part 146 is fitted into the rotary recess 136, so that the fitting part 140 is fitted into the fitting part 130. Preferably, the rotary recess 136 extends in a rotary manner from the rear end E2 to the front end E1 of the pinching part 110, and the bent convex part 146 extends in a bent manner from the end of the fitting protrusion 144 to the front end E1. Thus, when the extending rod part 142 moves in a direction approaching the side surface 112 of the pinching part 110, the bent convex part 146 is inserted into the rotary recess 136 from the rear end E2 to the front end E1 through the protruding wall 138 (i.e., the inner wall of the fitting recess 134) between the extending recess 132 and the rotary recess 136, and the fitting protrusion 144 and the extending rod part 142 are sequentially fitted into the fitting recess 134 and the extending recess 132, so that the fitting part 140 is fitted into the fitting part 130.

[0060] With the above settings, in this embodiment, the bent convex portion 146 of the fitting portion 140 is further fitted in the rotation concave portion 136 of the fitted portion 130 formed in the pinching portion 110 along the front-rear direction (i.e., the length direction L), so that the contact area between the fitting portion 140 and the fitted portion 130 that are fitted to each other increases and interference is formed, improving the structural strength of the slider tab 100 for a zipper. Furthermore, when the slider tab 100 for a zipper is in the closed state, the fitting portion 140 forms a barb shape and can hook the protrusion wall 138 (i.e., the inner wall of the fitting recess 134) between the extension recess 132 and the rotation concave portion 136 with the notch (i.e., the inner wall of the fitting protrusion 144) between the extension rod portion 142 and the bent convex portion 146. Thus, when the slider tab 100 for a zipper is installed on the tab mounting portion 52 of the slider 50 for a zipper, even if the user pinches the pinching portion 110 of the slider tab 100 for a zipper and operates the slider tab 100 for a zipper in the front-rear direction (i.e., the length direction L), the fitting portion 140 is not easily detached from the fitted portion 130. Accordingly, the slider tab 100 for a zipper in the closed state is not easily loosened during use and has sufficient structural strength and good operability. However, as long as the fitting portion 140 can be fitted to the fitted portion 130 along the side surface 112 of the pinching portion 110, the present invention does not limit the specific structures of the fitted portion 130 and the fitting portion 140, which can be adjusted according to requirements.

[0061] In addition, in this embodiment, as Figures 1 to 6 shown, the slider connection portion 120 extends from the first side S1 in the width direction W to the second side S2 opposite to the first side S1 at the front end E1 of the pinching portion 110, and the fitted portion 130 is located on the side surface 112 of the pinching portion 110 corresponding to the second side S2. That is to say, one end of the slider connection portion 120 is connected to the portion of the front end E1 of the pinching portion 110 close to the first side S1, and the other end of the slider connection portion 120 is connected to the side surface 112 of the second side S2 of the pinching portion 110 by fitting the fitting portion 140 formed at the end portion 120a of the slider connection portion 120 along the side surface 112 to the fitted portion 130, so that the slider connection portion 120 is closed to form a ring shape. With the above settings, the slider connection portion 120 that is closed to form a ring shape straddles the first side S1 and the second side S2 along the width direction W at the front end E1 of the pinching portion 110, thereby being able to improve the connection effect and structural strength of the slider connection portion 120 that is closed to form a ring shape. Accordingly, the slider tab 100 for a zipper in the closed state has sufficient structural strength. However, as long as the slider connection portion 120 can be installed on the tab mounting portion 52 of the slider 50 for a zipper and is closed to form a ring shape by the fitting of the fitting portion 140 and the fitted portion 130, the present invention does not limit the specific structure and relative position of the slider connection portion 120, which can be adjusted according to requirements.

[0062] Furthermore, in this embodiment, asFigures 1 to 6 As shown, the pinching portion 110, the slider connecting portion 120, and the fitting portion 140 are made of a soft material, and the pinching portion 110, the slider connecting portion 120, the fitting portion 140, and the fitted portion 130 are different parts of an integrally formed single member. As an example, a resin material that can be compressed and deformed (flexible or elastic) can be selected for manufacturing. In this way, the slider tab 100 for the zipper can be made of the same material to reduce the manufacturing process and lower the manufacturing cost (for example, completed through one injection molding process), and the fitting portion 140 can be easily fitted into the fitted portion 130 due to its material properties (capable of being compressed and deformed). Preferably, the shape and size of the fitting portion 140 correspond to the shape and size of the fitted portion 130 (for example, the size of the fitting portion 140 is greater than or equal to the size of the fitted portion 130), so that the fitting portion 140 is fitted into the fitted portion 130 to form a tight fit. That is, the fitting portion 140 with a slightly larger or approximately equal size is squeezed and fitted into the fitted portion 130 based on its material properties, so that the outer surface of the fitting portion 140 closely abuts against the inner surface of the fitted portion 130. In this way, the fitting effect between the fitting portion 140 and the fitted portion 130 can be improved.

[0063] In addition, as an example, when a soft material such as a resin material is selected to manufacture the pinching portion 110, the slider connecting portion 120, and the fitting portion 140, etc., as Figures 1 to 4 shown, a recessed portion 114 is formed at a position on the outer surface of the pinching portion 110 close to the first side S1, and in the perspective of viewing from the front of the pinching portion 110 (that is, Figure 2 the Figure 4 perspective), the recessed portion 114 does not overlap with the area corresponding to the fitted portion 130 on the pinching portion 110. Through the above setting, as Figure 3 shown, the first side S1 of the pinching portion 110 is formed with a recessed portion 114 and the second side S2 is formed with a fitted portion 130. The thickness of the area on the first side S1 of the pinching portion 110 corresponding to the recessed portion 114 (that is, the distance d1 between the outer surfaces on the opposite sides of the recessed portion 114 in the thickness direction T) is approximately similar to the thickness of the area on the second side S2 corresponding to the fitted portion 130 (that is, the distance d2 between the outer surfaces on the opposite sides of the pinching portion 110 in the thickness direction T minus the distance d3 between the inner wall surfaces on the opposite sides of the fitted portion 130 in the thickness direction T). In this way, during the process of manufacturing the slider tab 100 for the zipper by injection molding with a resin material, it is possible to avoid surface indentations caused by different rates of thermal expansion and contraction due to the thickness difference on the opposite sides of the pinching portion 110, so that the pinching portion 110 of the slider tab 100 for the zipper has an aesthetically pleasing appearance.

[0064] However, in Figure 7In a modified example, the slider tab 100A for a zipper has a similar structural arrangement to the aforementioned slider tab 100 for a zipper. The main difference is that a recessed portion 114 formed on the outer surface of the aforementioned pinching portion 110 is not formed on the outer surface of the pinching portion 110A. For the specific structures of the slider connection portion 120, the engaged portion 130, and the engaging portion 140, reference may be made to the foregoing content, and no further elaboration will be provided here. It can be seen from this that although this embodiment proposes to form the recessed portion 114 on the outer surface of the pinching portion 110 in the method of injection molding the slider tab 100 for a zipper using a resin material to avoid surface dents on the pinching portion 110, in the case of using a resin material, the recessed portion 114 may not be formed on the outer surface of the pinching portion 110. Alternatively, the slider tab 100 for a zipper may also be made of a material other than a resin material and / or by a process other than injection molding. The present invention does not limit the setting of the recessed portion 114, nor the material of the slider tab 100 for a zipper and the type of manufacturing process, which can be adjusted according to requirements.

[0065] In summary, in the slider tab for a zipper of the present invention, the slider connection portion extends outward from the front end of the pinching portion, the engaged portion is located on one side surface of the pinching portion in the width direction, and the engaging portion extends outward from the end of the slider connection portion. Among them, the slider connection portion is adapted to pass through the tab mounting portion of the slider for a zipper, and the engaging portion is fitted into the engaged portion along the side surface of the pinching portion, so that the slider connection portion is closed to form a ring. In this way, the slider tab for a zipper can be made of the same material, and can be installed and fixed by the mutual cooperation of its own structure (that is, the engaged portion and the engaging portion), so that it can be easily installed on the slider by opening or closing. In particular, the engaging portion is fitted into the engaged portion along the side surface of the pinching portion, which can make the engaging portion and the engaged portion have a good connection effect, so that the slider tab for a zipper in the closed state is not easily loosened during use.
