CROSS-REFERENCE TO RELATED APPLICATION

This application claims the priority benefit of China application serial no. 202311821982.6, filed on Dec. 26, 2023. The entirety of the above-mentioned patent application is hereby incorporated by reference herein and made a part of this specification.

BACKGROUND
Technical Field

The disclosure relates to the technology of the fastener field, and in particular relates to a tab pull for a fastener.

Description of Related Art

A conventional fastener usually includes a fastener chain comprising a pair of fastener stringers, each fastener stringer consisting of a strip of fastener tape and multiple element columns arranged thereon. The fastener also includes a slider installed on a fastener stringer to open or close the element columns by sliding. In addition, a tab pull may also be disposed on the slider according to requirements.

In the prior art, a slider for a fastener usually includes a slider connection portion for installation on a slider, and a gripping portion for the user to grasp with fingers to operate the slider. The tab pull may employ a cord as the slider connection portion. A gripping portion formed of resin material may be injection molded at the extreme end of the cord, thereby the cord may be passed through the tab pull installation portion of the slider to install the tab pull on the slider, and the slider may be driven to slide through the gripping portion at the extreme end of the cord.

However, such a tab pull needs to be manufactured using different materials (i.e., the cord used as the slider connection portion, the resin material used to form the gripping portion, etc.), resulting in an increase in required processes and manufacturing costs. In addition, if the structure of the tab pull is improved in order to reduce the manufacturing processes, the structural strength and operability of the improved tab pull need to be taken into consideration.

FIG. 7 is a three-dimensional schematic diagram of a tab pull installed on a slider according to a variation of the disclosure. The specific structure of the tab pull 100 and its modifications in one embodiment of the disclosure, as well as the installation means when the tab pull 100 is applied to the slider 50, etc., will be described below with reference to FIG. 1 to FIG. 7. However, the disclosure is not limited thereto, and the disclosure may be adjusted according to requirements.

Referring to FIG. 1 to FIG. 6, in this embodiment, the tab pull 100 is adapted to be installed on the slider 50, and includes a gripping portion 110, a slider connection portion 120, an engaged portion 130, and an engagement portion 140. The gripping portion 110 is configured in a sheet shape for the user to grasp with fingers to operate the tab pull 100. The slider connection portion 120 extends outward from the front end E1 of the gripping portion 110 and is adapted to pass through the tab pull installation portion 52 of the slider 50 (as shown in FIG. 5 and FIG. 6). The engaged portion 130 is located at one of the side surfaces 112 of the gripping portion 110 in the width direction W. The engagement portion 140 extends outward from the end portion 120a of the slider connection portion 120, and the engagement portion 140 is fitted into the engaged portion 130 along the side surface 112 of the gripping portion 110, so that the slider connection portion 120 is closed to form an annular shape.

Specifically, in this embodiment, the gripping portion 110 is, for example, a substantially elongated strip-shaped structure extending in the front-rear direction (i.e., the length direction L). However, the gripping portion 110 may also be arranged into a desired shape according to requirements, and its dimensions (length, width, thickness) may be adjusted according to requirements, and the disclosure is not limited thereto. Correspondingly, the slider connection portion 120 is a thin and elongated strip-shaped structure extending outward from the front end E1 of the gripping portion 110, thereby passing through the installation hole 52a on the tab pull installation portion 52 of the slider 50. Preferably, the dimension of the slider connection portion 120 in the width direction W is less than the dimension of the gripping portion 110 in the width direction W. That is, in comparison to the sheet shaped gripping portion 110, the slider connection portion 120 is configured in an elongated strip shape. In this way, the slider connection portion 120 may be bent without requiring excessive length, and easily form a ring shape by passing through the tab pull installation portion 52 of the slider 50 and looping back to the side surface 112 of the gripping portion 110. However, as long as the slider connection portion 120 may be installed by passing through the tab pull installation portion 52, its dimensions (length, width, thickness) may be adjusted according to requirements, and the disclosure is not limited thereto.

Furthermore, in this embodiment, the engaged portion 130 and the engagement portion 140 are respectively arranged at the gripping portion 110 and the slider connection portion 120. The engaged portion 130 is, for example, a recessed structure formed on the side surface 112 of the gripping portion 110, and the engagement portion 140 is, for example, a protruding structure formed on the end portion 120a of the slider connection portion 120 opposite to the gripping portion 110. That is, one end of the slider connection portion 120 is connected to the front end E1 of the gripping portion 110, and the other end of the slider connection portion 120 is formed with an engagement portion 140. Thereby the slider connection portion 120 may be connected to the side surface 112 of the gripping portion 110 through the engagement of the engagement portion 140 and the engaged portion 130, so that the slider connection portion 120 may be closed to form an annular shape. In this way, when the engagement portion 140 moves into the engaged portion 130 in a direction approaching the gripping portion 110 (as shown in FIG. 1 and FIG. 2), the tab pull 100 is in a closed state (the slider connection portion 120 is closed to form an annular shape), and when the engagement portion 140 moves out of the engaged portion 130 in a direction away from the gripping portion 110 (as shown in FIG. 4), the tab pull 100 is in an open state.

It may be seen from this that when the tab pull 100 is in the open state, as shown in FIG. 4 and FIG. 5, the engagement portion 140 formed by the end portion 120a of the slider connection portion 120 is separated from the engaged portion 130, thereby the end portion 120a of the slider connection portion 120 of the tab pull 100 may pass through the installation hole 52a of the tab pull installation portion 52 of the slider 50 together with the engagement portion 140. After the slider connection portion 120 passes through the tab pull installation portion 52, as shown in FIG. 6, the engagement portion 140 formed by the end portion 120a of the slider connection portion 120 may be fitted into the engaged portion 130, so that the slider connection portion 120 may be closed to form an annular shape. In this way, the tab pull 100 may be made of the same material, and may be installed and secured by engaging the structures thereon (i.e., the engaged portion 130 and the engagement portion 140), thereby the tab pull 100 may be easily installed on the slider 50 by means of opening or closing. In particular, the engagement portion 140 is fitted into the engaged portion 130 along the side surface 112 of the gripping portion 110, so that the engagement portion 140 and the engaged portion 130 may achieve a good connection, thereby the tab pull 100 in the closed state is less likely to become loose or detached during use. Accordingly, the tab pull 100 may reduce the manufacturing processes and reduce manufacturing costs, and has sufficient structural strength and good operability.

As an example, in this embodiment, as shown in FIG. 1 to FIG. 4, the engaged portion 130 includes an extending recessed portion 132 extending along the side surface 112 of the gripping portion 110, and an engagement recessed portion 134 located at an extreme end of the extending recessed portion 132. Correspondingly, the engagement portion 140 includes an extension rod portion 142 extending from the end portion 120a of the slider connection portion 120 along the side surface 112 of the gripping portion 110, and an engagement protrusion 144 located at the extreme end of the extension rod portion 142. The extension rod portion 142 is fitted into the extending recessed portion 132 along the side surface 112 of the gripping portion 110, and the engagement protrusion 144 is fitted into the engagement recessed portion 134, so that the engagement portion 140 is fitted into the engaged portion 130. Preferably, the extending recessed portion 132 extends along the side surface 112 of the gripping portion 110 from the front end E1 of the gripping portion 110 to the rear end E2 of the gripping portion 110, and the engagement recessed portion 134 is located at the rear end E2 of the gripping portion 110. That is, the extending recessed portion 132 is, for example, an elongated strip-shaped groove formed on the side surface 112 of the gripping portion 110 and connected to the front end E1 and the rear end E2, and the engagement recessed portion 134 is a transverse notch at the extreme end of the elongated strip-shaped groove. In contrast, the extension rod portion 142 is also configured as an elongated rod portion extending from the front end E1 to the rear end E2 corresponding to the length of the extending recessed portion 132, and the engagement protrusion 144 is a transverse protrusion at the extreme end of the elongated rod portion. Furthermore, the extending direction of the extending recessed portion 132 (substantially corresponding to the length direction L of the side surface 112 of the gripping portion 110) intersects the extending direction of the engagement recessed portion 134 (substantially corresponding to the width direction W) to form a substantially L-shape, and the extending direction of the extension rod portion 142 intersects the extending direction of the engagement protrusion 144 to form a substantially L-shape.

Through the above arrangement, in this embodiment, the extending recessed portion 132 of the engaged portion 130 is formed on the side surface 112 of the gripping portion 110 across the front end E1 and the rear end E2 in the front-rear direction (i.e., the length direction L) and further opens outwardly at the front end E1, the side surface 112, and the rear end E2. Thereby the extension rod portion 142 of the engagement portion 140 crosses the front end E1 and the rear end E2 in the front-rear direction (i.e., the length direction L) and is fitted into the engaged portion 130 formed on the side surface 112 of the gripping portion 110 in the extending recessed portion 132, thereby increasing the contact area between the engagement portion 140 and the engaged portion 130 that are fitted to each other, so that the structural strength of the tab pull 100 is improved. In particular, when the engagement portion 140 moves into the engaged portion 130 in a direction approaching the side surface 112, the extension rod portion 142 may enter the extending recessed portion 132 from the opening of the front end E1 of the extending recessed portion 132, and the engagement protrusion 144 may enter the engagement recessed portion 134 from the opening of the rear end E2 of the extending recessed portion 132 (i.e., the extreme end of the extending recessed portion 132), thereby the engagement portion 140 may be easily fitted to the engaged portion 130. Furthermore, the engagement protrusion 144 of the engagement portion 140 is fitted into the engagement recessed portion 134 of the engaged portion 130 along the width direction W, thereby the engagement protrusion 144 may interfere with the inner wall surface of the engagement recessed portion 134 in the front-rear direction (i.e., the length direction L). Thereby, when the tab pull 100 is installed on the tab pull installation portion 52 of the slider 50, even if a user grasps the gripping portion 110 of the tab pull 100 with fingers and operates the tab pull 100 in the front-rear direction (i.e., the length direction L), the engagement portion 140 is not easily detached from the engaged portion 130. Accordingly, the tab pull 100 in the closed state is less likely to become loose or detached during use, and has sufficient structural strength and good operability.

Furthermore, in this embodiment, the engaged portion 130 further includes a rotating recessed portion 136 located at the extreme end of the engagement recessed portion 134, and the engagement portion 140 further includes a bent protruding portion 146 located at the extreme end of the engagement protrusion 144. The extension direction of the rotating recessed portion 136 (substantially corresponding to the length direction L) intersects the extending direction of the engagement recessed portion 134 (substantially corresponding to the width direction W) so that the extreme end of the engaged portion 130 forms a hook shape. Correspondingly, the extending direction of the bent protruding portion 146 intersects the extending direction of the engagement protrusion 144 so that the end of the engagement portion 140 forms a hook shape. In this way, when the extension rod portion 142 is fitted into the extending recessed portion 132 along the side surface 112 of the gripping portion 110 and the engagement protrusion 144 is fitted into the engagement recessed portion 134, the bent protruding portion 146 is fitted into the rotating recessed portion 136 so that the engagement portion 140 is fitted into the engaged portion 130. Preferably, the rotating recessed portion 136 rotates and extends from the rear end E2 of the gripping portion 110 toward the front end E1, and the bent protruding portion 146 bends and extends from the extreme end of the engagement protrusion 144 toward the front end E1. In this way, when the extension rod portion 142 moves in a direction approaching the side surface 112 of the gripping portion 110, the bent protruding portion 146 is inserted into the rotating recessed portion 136 from the rear end E2 toward the front end E1 through the protruding wall 138 between the extending recessed portion 132 and the rotating recessed portion 136 (i.e., the inner wall of the engagement recessed portion 134), and the engagement protrusion 144 and the extension rod portion 142 are fitted into the engagement recessed portion 134 and the extending recessed portion 132 in sequence, so that the engagement portion 140 is fitted into the engaged portion 130.

Through the above arrangement, in this embodiment, the bent protruding portion 146 of the engagement portion 140 is further fitted into the rotating recessed portion 136 formed in the engaged portion 130 of the gripping portion 110 along the front-rear direction (i.e., the length direction L), thereby increasing the contact area between the engagement portion 140 and the engaged portion 130 that are fitted to each other and creating interference, so that the structural strength of the tab pull 100 is improved. Furthermore, when the tab pull 100 is in a closed state, the engagement portion 140 forms a barb-like shape and may hook the protruding wall 138 (i.e., the inner wall of the engagement recessed portion 134) between the extending recessed portion 132 and the rotating recessed portion 136 with the notch (i.e., the inner wall of the engagement protrusion 144) between the extension rod portion 142 and the bent protruding portion 146. Thereby, when the tab pull 100 is installed on the tab pull installation portion 52 of the slider 50, even if a user grasps the gripping portion 110 of the tab pull 100 with fingers and operates the tab pull 100 in the front-rear direction (i.e., the length direction L), the engagement portion 140 is not easily detached from the engaged portion 130. Accordingly, the tab pull 100 in the closed state is less likely to become loose or detached during use, and has sufficient structural strength and good operability. However, as long as the engagement portion 140 may be fitted into the engaged portion 130 along the side surface 112 of the gripping portion 110, the disclosure does not limit the specific structures of the engaged portion 130 and the engagement portion 140, which may be adjusted according to requirements.

In addition, in this embodiment, as shown in FIG. 1 to FIG. 6, 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 gripping portion 110, and the engaged portion 130 is located on the side surface 112 corresponding to the second side S2 of the gripping portion 110. That is, one end of the slider connection portion 120 is connected to a portion of the front end E1 of the gripping portion 110 close to the first side S1. The other end of the slider connection portion 120 is fitted to the engaged portion 130 along the side surface 112 through the engagement portion 140 formed at the end portion 120a of the slider connection portion 120 to connect to the side surface 112 of the second side S2 of the gripping portion 110, so that the slider connection portion 120 is closed to form an annular shape. With the above arrangement, the slider connection portion 120 that is closed to form an annular shape crosses the first side S1 and the second side S2 along the width direction W at the front end E1 of the gripping portion 110, thereby improving the connection and structural strength of the closed and annular-shaped slider connection portion 120. Accordingly, the tab pull 100 in the closed state has sufficient structural strength. However, as long as the slider connection portion 120 may be installed on the tab pull installation portion 52 of the slider 50 and may be closed by fitting the engagement portion 140 into the engaged portion 130, thereby forming an annular shape, the disclosure does not limit the specific structure and relative position of the slider connection portion 120, which may be adjusted according to requirements.

Furthermore, in this embodiment, as shown in FIG. 1 to FIG. 6, the gripping portion 110, the slider connection portion 120, and the engagement portion 140 are made of soft material, and the gripping portion 110, the slider connection portion 120, the engagement portion 140, and the engaged portion 130 are different portions of a single component formed integrally. As an example, a resin material that may deform through compression (has flexibility or elasticity) may be used. In this way, the tab pull 100 may be made of the same material to reduce the manufacturing processes and reduce the manufacturing costs (e.g., manufacturing is done through one injection molding process), and the engagement portion 140 may be easily fitted into the engaged portion 130 due to its material characteristics (capable of deformation by compression). Preferably, the shape and dimensions of the engagement portion 140 correspond to the shape and dimension of the engaged portion 130 (e.g., the dimensions of the engagement portion 140 is greater than or equal to the dimensions of the engaged portion 130), so that the engagement portion 140 fits into the engaged portion 130 to form a tight fit. That is, the engagement portion 140 that is slightly larger or approximately the same dimension is squeezed and fitted into the engaged portion 130 based on its material characteristics, so that the outer surface of the engagement portion 140 is in close contact with the inner surface of the engaged portion 130. In this way, the engagement effect between the engagement portion 140 and the engaged portion 130 may be improved.

In addition, as an example, when soft materials such as resin materials are used to manufacture the gripping portion 110, the slider connection portion 120, the engagement portion 140, etc., as shown in FIG. 1 to FIG. 4, a recessed portion 114 is formed on a portion of the outer surface of the gripping portion 110 close to the first side S1. When viewed from the front of the gripping portion 110 (i.e., the viewing angle of FIG. 2 and FIG. 4), the recessed portion 114 does not overlap with the region corresponding to the engaged portion 130 on the gripping portion 110. With the above arrangement, as shown in FIG. 3, a recessed portion 114 is formed at the first side S1 of the gripping portion 110 and the engaged portion 130 is formed at the second side S2. The thickness (i.e., the distance d1 in the thickness direction T between the outer surfaces on opposite sides of the recessed portion 114) of the region corresponding to the recessed portion 114 on the first side S1 of the gripping portion 110 is substantially similar to the thickness (i.e., the distance d2 in the thickness direction T between the outer surfaces on opposite sides of the gripping portion 110 minus the distance d3 in the thickness direction T between the inner wall surfaces of opposite sides of the engaged portion 130) of the region corresponding to the engaged portion 130 on the second side S2. In this way, during the process of manufacturing the tab pull 100 by injection molding of a resin material, it is possible to prevent surface dents on the gripping portion 110 caused by the difference in the speed of thermal expansion and contraction caused by the difference in thickness on the opposite sides. Consequently, the gripping portion 110 of the tab pull 100 has an aesthetically pleasing appearance.

However, in the modified example of FIG. 7, the tab pull 100A has a similar structural arrangement to the aforementioned tab pull 100. The main difference is that the outer surface of the gripping portion 110A does not feature the recessed portion 114 that is formed on the outer surface of the aforementioned gripping portion 110. For the description of the rest of the specific structures of the slider connection portion 120, the engaged portion 130, and the engagement portion 140, reference may be made to the foregoing content and will not be repeated herein. It may be seen from this that although this embodiment proposes the formation of a recessed portion 114 on the outer surface of the gripping portion 110 to prevent surface indentations on the gripping portion 110 when manufacturing a tab pull 100 by injection molding using resin material, in cases where resin material is used, it is also possible to omit the formation of the recessed portion 114 on the outer surface of the gripping portion 110. Alternatively, the tab pull 100 may be manufactured using materials other than resin materials and/or using a process other than injection molding. The disclosure does not limit whether the recessed portion 114 is arranged, as well as the material and manufacturing process of the tab pull 100, which may be adjusted according to requirements.

To sum up, in the tab pull of a fastener of the disclosure, the slider connection portion extends outward from the front end of the gripping portion, the engaged portion is located on one side surface of the gripping portion in the width direction, and the engagement portion extends outward from the end portion of the slider connection portion. The slider connection portion is adapted to pass through the tab pull installation portion of the slider, and the engagement portion is fitted into the engaged portion along the side surface of the gripping portion, so that the slider connection portion is closed to form an annular shape. In this way, the tab pull may be made of the same material, and may be installed and secured by engaging the structures thereon (i.e., the engaged portion and the engagement portion), thereby the tab pull may be easily installed on the slider by means of opening or closing. In particular, the engagement portion is fitted into the engaged portion along the side surface of the gripping portion, so that the engagement portion and the engaged portion may achieve a good connection, thereby the tab pull in the closed state is less likely to become loose or detached during use. Preferably, the extending recessed portion of the engaged portion extends from the front end of the gripping portion to the rear end of the gripping portion along the side surface of the gripping portion, and the engagement recessed portion of the engaged portion is located at the rear end of the extending recessed portion, thereby increasing the contact area between the engagement portion and the engaged portion that are fitted to each, so that the structural strength of the tab pull is improved. Accordingly, the tab pull for the fastener of the disclosure may reduce the manufacturing processes and reduce manufacturing costs, and has sufficient structural strength and good operability.

Finally, it should be noted that the foregoing embodiments are only used to illustrate the technical solutions of the disclosure, but not to limit the disclosure; although the disclosure has been described in detail with reference to the foregoing embodiments, persons of ordinary skill in the art should understand that the technical solutions described in the foregoing embodiments may still be modified, or parts or all of the technical features thereof may be equivalently replaced; however, these modifications or substitutions do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the disclosure.
