Description

Technical Field

[0001] The present invention relates to the technology in the field of fasteners, and particularly to a tab pull for a fastener.

Background Art

[0002] A general fastener usually consists of a fastener chain composed of a pair of fastener stringers including a strip-shaped fastener tape and a plurality of element columns arranged on the fastener tape, and a slider for a fastener attached to the fastener stringer and slid to open and close the element columns. Further, a tab pull for a fastener can be installed on the slider for a fastener as needed.

[0003] In the prior art, a tab pull for a fastener usually includes a slider connection part for attaching to the slider for a fastener and a knob part for a user to pinch with a finger to operate the tab pull for a fastener. Among these, a string can be used as the slider connection part of the tab pull for a fastener, and a knob part formed of a resin material is installed at the end of the string by injection molding. Thereby, the tab pull for a fastener is attached to the slider for a fastener by passing the string through the handle attachment part of the slider for a fastener, and the slide of the slider for a fastener can be driven by the knob part at the end of the string.

[0004] However, such a tab pull for a fastener needs to be manufactured using different materials (i.e., the string as the slider connection part, the resin material for forming the knob part, etc.), which leads to an increase in the required processes and manufacturing costs. Also, when improving the structure of the tab pull for a fastener to reduce the manufacturing process, it is necessary to further consider the structural strength and operability of the improved tab pull for a fastener.

[0006] The present invention is a pull tab for a fastener suitable for attachment to a slider for a fastener, comprising a knob portion formed in a sheet shape, a slider connection portion extending outward from the front end of the knob portion and suitable for passing through a pull tab attachment portion of the slider for the fastener, a fitting portion located on one side surface in the width direction of the knob portion, and a fitting portion extending outward from an end portion of the slider connection portion, wherein the fitting portion fits into the fitting portion along the side surface of the knob portion to close the slider connection portion and form an annular shape.

[0007] In an embodiment of the present invention, the fitting portion includes an extending recess extending along the side surface of the knob portion and a fitting recess located at the end of the extending recess, and the fitting portion includes an extending rod portion extending from the end of the slider connection portion along the side surface of the knob portion and a fitting protrusion located at the end of the extending rod portion. The extending rod portion fits into the extending recess along the side surface of the knob portion, and the fitting protrusion fits into the fitting recess to fit the fitting portion into the fitting portion.

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

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

[0010] In an embodiment of the present invention, the fitted portion further includes a rotation recess located at the end of the fitting recess, the fitting portion further includes a bending protrusion located at the end of the fitting protrusion, the extending direction of the rotation recess intersects the extending direction of the fitting recess to form a hook shape at the end of the fitted portion, the extending direction of the bending protrusion intersects the extending direction of the fitting protrusion to form a hook shape at the end of the fitting portion, and the bending protrusion is fitted into the rotation recess to fit the fitting portion to the fitted portion.

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

Best Mode for Carrying Out the Invention

[0018] In order to make the above features and advantages of the present invention clearer and easier to understand, embodiments will be given below and described in detail with reference to the drawings.

[0019] Here, exemplary embodiments of the present invention will be referred to in detail, and examples of the exemplary embodiments are shown in the drawings. Among them, FIG. 1 is a perspective explanatory view of the handle for a fastener in a closed state according to an embodiment of the present invention, FIG. 2 is a front explanatory view of the handle for a fastener shown in FIG. 1 in a closed state, FIG. 3 is a top explanatory view of the handle for a fastener shown in FIG. 1 in a closed state, FIG. 4 is a front explanatory view of the handle for a fastener shown in FIG. 1 in an open state, FIG. 5 is a perspective explanatory view of the process in which the handle for a fastener shown in FIG. 1 is attached to the slider for a fastener, FIG. 6 is a perspective explanatory view after the handle for a fastener shown in FIG. 5 is attached to the slider for a fastener, and FIG. 7 is a perspective explanatory view after the handle for a fastener according to a modification of the present invention is attached to the slider for a fastener. Hereinafter, with reference to FIGS. 1 to 7, the specific structure of the handle 100 for a fastener and its modification in an embodiment of the present invention, and the attachment means and the like when applied to the slider 50 for a fastener will be described. However, the present invention is not limited thereto and can be adjusted as needed.

[0020] Referring to FIGS. 1 to 6, in the present embodiment, the fastener pull tab 100 is suitable for attachment to the fastener slider 50 and includes a knob portion 110, a slider connection portion 120, a fitted portion 130, and a fitting portion 140. The knob portion 110 is formed in a sheet shape and is operated by the user to pinch it with a finger to operate the fastener pull tab 100. The slider connection portion 120 extends outward from the front end E1 of the knob portion 110 and is suitable for passing through the pull tab attachment portion 52 of the fastener slider 50 (see FIGS. 5 and 6). The fitted portion 130 is located on one side surface 112 in the width direction W of the knob portion 110. The fitting portion 140 extends outward from the end portion 120a of the slider connection portion 120, and the fitting portion 140 fits into the fitted portion 130 along the side surface 112 of the knob portion 110 to close the slider connection portion 120 to form an annular shape.

[0021] Specifically, in the present embodiment, the knob portion 110 has, for example, a substantially elongated structure extending in the front-rear direction (i.e., the length direction L), but can be provided in a desired shape as needed, and its dimensions (length, width, thickness) can be adjusted as needed, and the present invention is not limited thereto. Correspondingly, the slider connection portion 120 is an elongated strip-shaped structure extending outward from the front end E1 of the knob portion 110, whereby it can pass through the attachment hole 52a on the pull tab attachment portion 52 of the fastener slider 50. Preferably, the dimension of the slider connection portion 120 in the width direction W is smaller than the dimension of the knob portion 110 in the width direction W. That is, with respect to the knob portion 110 formed in a sheet shape, the slider connection portion 120 is formed in a strip shape. In this way, the slider connection portion 120 can be bent without requiring an excessively long length, and can be easily wound around the side surface 112 of the knob portion 110 after passing through the pull tab attachment portion 52 of the fastener slider 50 to form an annular shape. However, as long as the slider connection portion 120 can pass through the pull tab attachment portion 52 for attachment, its dimensions (length, width, thickness) can be adjusted as needed, and the present invention is not limited thereto.

[0022] In addition, in the present embodiment, the engaged portion 130 and the engaging portion 140 are respectively installed on the knob portion 110 and the slider connection portion 120. Among these, the engaged portion 130 is, for example, a concave structure formed on the side surface 112 of the knob portion 110, and the engaging portion 140 is, for example, a convex structure formed on the end portion 120a of the slider connection portion 120 opposite to the knob portion 110. That is, one end of the slider connection portion 120 is connected to the front end E1 of the knob portion 110, and the engaging portion 140 is formed at the other end of the slider connection portion 120. Thereby, the slider connection portion 120 is connected to the side surface 112 of the knob portion 110 through the engagement of the engaging portion 140 and the engaged portion 130, and the slider connection portion 120 can be closed to form an annular shape. In this way, when the engaging portion 140 moves to the engaged portion 130 in the direction approaching the knob portion 110 (see FIGS. 1 and 2), the fastener handle 100 is in a closed state (the slider connection portion 120 is closed to form an annular shape), and when the engaging portion 140 moves from the engaged portion 130 in the direction away from the knob portion 110 (see FIG. 4), the fastener handle 100 is in an open state.

[0023] As can be understood from this, when the fastener handle 100 is in the open state, as shown in FIGS. 4 and 5, the fitting portion 140 formed at the end portion 120a of the slider connection portion 120 is separated from the fitted portion 130. Thereby, the fastener handle 100 can pass through the mounting hole 52a of the handle mounting portion 52 of the fastener slider 50 together with the fitting portion 140 by the end portion 120a of the slider connection portion 120. After the slider connection portion 120 passes through the handle mounting portion 52, as shown in FIG. 6, the fitting portion 140 formed at the end portion 120a of the slider connection portion 120 is fitted to the fitted portion 130, and the slider connection portion 120 can be closed to form an annular shape. In this way, the fastener handle 100 can be manufactured using the same material and can be attached and fixed by the combination of its own structure (i.e., the fitted portion 130 and the fitting portion 140), and thereby can be easily attached to the fastener slider 50 by opening and closing. In particular, the fitting portion 140 is fitted to the fitted portion 130 along the side surface 112 of the knob portion 110, and a good connection effect can be provided between the fitting portion 140 and the fitted portion 130, so that the fastener handle 100 in the closed state is not easily loosened during use. Therefore, the fastener handle 100 can reduce the manufacturing process and reduce the manufacturing cost, and has sufficient structural strength and good operability.

[0024] As an example, in the present embodiment, as shown in FIGS. 1 to 4, the fitting portion 130 includes an extending recess 132 that extends along the side surface 112 of the knob portion 110, and a fitting recess 134 that is located at the end of the extending recess 132. Correspondingly, the fitting portion 140 includes an extending rod portion 142 that extends from the end portion 120a of the slider connection portion 120 along the side surface 112 of the knob portion 110, and a fitting protrusion 144 that is located at the end of the extending rod portion 142. Among these, the extending rod portion 142 fits into the extending recess 132 along the side surface 112 of the knob portion 110, and the fitting protrusion 144 fits into the fitting recess 134, fitting the fitting portion 140 to the fitting portion 130. Preferably, the extending recess 132 extends from the front end E1 to the rear end E2 of the knob portion 110 along the side surface 112 of the knob portion 110, and the fitting recess 134 is located at the rear end E2 of the knob portion 110. That is, the extending recess 132 is, for example, a long groove formed on the side surface 112 of the knob portion 110 and communicating with the front end E1 and the rear end E2, and the fitting recess 134 is a lateral notch at the end of the long groove. Correspondingly, the extending rod portion 142 is also installed as a long rod portion that extends from the front end E1 to the rear end E2 corresponding to the length of the extending recess 132, and the fitting protrusion 144 is a lateral protrusion at the end of the long rod portion. Further, the extending direction of the extending recess 132 (substantially corresponding to the length direction L of the side surface 112 of the knob portion 110) intersects with the extending direction of the fitting 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 fitting protrusion 144 to form a substantially L shape.

[0025] With the above arrangement, in the present embodiment, the extension recess 132 of the fitted portion 130 is formed on the side surface 112 of the knob portion 110 straddling the front end E1 and the rear end E2 in the front-rear direction (i.e., the length direction L), and is further open to the outside at the front end E1, the side surface 112, and the rear end E2. Thereby, the extension rod portion 142 of the fitting portion 140 fits into the extension recess 132 of the fitted portion 130 formed on the side surface 112 of the knob portion 110 straddling the front end E1 and the rear end E2 in the front-rear direction (i.e., the length direction L). Thereby, the contact area between the fitting portion 140 and the fitted portion 130 that fit into each other increases, improving the structural strength of the fastener handle 100. In particular, in the process of the fitting portion 140 moving toward the fitted portion 130 in the direction approaching the side surface 112, the extension rod portion 142 can enter the extension recess 132 from the open portion at the front end E1 of the extension recess 132, and the fitting protrusion 144 can enter the fitting recess 134 from the open portion (i.e., the end of the extension recess 132) at the rear end E2 of the extension recess 132. Thereby, the fitting portion 140 can be easily fitted to the fitted portion 130. Further, the fitting protrusion 144 of the fitting portion 140 is fitted into the fitting recess 134 of the fitted portion 130 along the width direction W. Thereby, the fitting protrusion 144 can interfere with the inner wall surface of the fitting recess 134 in the front-rear direction (i.e., the length direction L). Therefore, when the fastener handle 100 is attached to the handle attachment portion 52 of the fastener slider 50, even if the user pinches the knob portion 110 of the fastener handle 100 with a finger and operates the fastener handle 100 in the front-rear direction (i.e., the length direction L), the fitting portion 140 does not easily come off from the fitted portion 130. Therefore, the fastener handle 100 in the closed state does not easily loosen during use and has sufficient structural strength and good operability.

[0026] More specifically, in the present embodiment, the fitting portion 130 further includes a rotation recess 136 located at the end of the fitting recess 134, and the fitting portion 140 further includes a bending protrusion 146 located at the end of the fitting protrusion 144. Among these, the extending direction of the rotation recess 136 (substantially corresponding to the length direction L) intersects the extending direction of the fitting recess 134 (substantially corresponding to the width direction W) to form a hook shape at the end of the fitting portion 130. Correspondingly, the extending direction of the bending protrusion 146 intersects the extending direction of the fitting protrusion 144 to form a hook shape at the end of the fitting portion 140. Thus, when the extending rod portion 142 is fitted into the extending recess 132 along the side surface 112 of the knob portion 110 and the fitting protrusion 144 is fitted into the fitting recess 134, the bending protrusion 146 is fitted into the rotation recess 136 to fit the fitting portion 140 to the fitting portion 130. Preferably, the rotation recess 136 rotates and extends from the rear end E2 to the front end E1 of the knob portion 110, and the bending protrusion 146 bends and extends from the end of the fitting protrusion 144 to the front end E1. Thus, when the extending rod portion 142 moves in a direction approaching the side surface 112 of the knob portion 110, the bending protrusion 146 passes through the protruding wall 138 (i.e., the inner wall of the fitting recess 134) between the extending recess 132 and the rotation recess 136 and is inserted into the rotation recess 136 from the rear end E2 to the front end E1, and the fitting protrusion 144 and the extending rod portion 142 are sequentially fitted into the fitting recess 134 and the extending recess 132 to fit the fitting portion 140 to the fitting portion 130.

[0027] With the above installation, in this embodiment, the bending convex portion 146 of the fitting portion 140 is further fitted into the rotation concave portion 136 of the fitted portion 130 formed on the knob portion 110 along the front-rear direction (i.e., the length direction L). Thereby, 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 fastener handle 100. Further, when the fastener handle 100 is in the closed state, the fitting portion 140 forms an inverted hook shape and can hook onto the protruding wall 138 (i.e., the inner wall of the fitting recess 134) between the extension recess 132 and the rotation recess 136 by the notch (i.e., the inner wall of the fitting protrusion 144) between the extension rod portion 142 and the bending convex portion 146. Therefore, when the fastener handle 100 is attached to the handle attachment portion 52 of the fastener slider 50, even if the user pinches the knob portion 110 of the fastener handle 100 with a finger and operates the fastener handle 100 in the front-rear direction (i.e., the length direction L), the fitting portion 140 does not easily come off from the fitted portion 130. Thus, the fastener handle 100 in the closed state does not easily loosen 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 knob portion 110, the present invention does not limit the specific structures of the fitted portion 130 and the fitting portion 140 and can be adjusted as needed.

[0028] Also, in the present embodiment, as shown in FIGS. 1 to 6, slider connection portion 120 extends from first side S1 in the width direction W toward second side S2 opposite to first side S1 at front end E1 of knob portion 110, and engaged portion 130 is located on side surface 112 corresponding to second side S2 of knob portion 110. That is, one end of slider connection portion 120 is connected to a portion near first side S1 of front end E1 of knob portion 110, and the other end of slider connection portion 120 is connected to side surface 112 of second side S2 of knob portion 110 by fitting fitting portion 140 formed at end portion 120a of slider connection portion 120 to engaged portion 130 along side surface 112, thereby closing slider connection portion 120 to form a ring shape. By the above installation, slider connection portion 120 that closes to form a ring shape straddles first side S1 and second side S2 along width direction W at front end E1 of knob portion 110, thereby improving the connection effect and structural strength of slider connection portion 120 that closes to form a ring shape. Therefore, fastener handle 100 in the closed state has sufficient structural strength. However, as long as slider connection portion 120 can be attached to handle attachment portion 52 of fastener slider 50 and can be closed to form a ring shape by the fitting of fitting portion 140 and engaged portion 130, the present invention does not limit the specific structure and relative position of slider connection portion 120 and can be adjusted as needed.

[0029] Furthermore, in the present embodiment, as shown in FIGS. 1 to 6, the knob portion 110, the slider connection portion 120, and the fitting portion 140 are formed of a soft material, and the knob portion 110, the slider connection portion 120, the fitting portion 140, and the fitted portion 130 are different parts of a single member formed integrally. As an example, a resin material that can be deformed by compression (flexible or elastic) can be selected for manufacturing. In this way, the fastener handle 100 can be manufactured using the same material, reducing the manufacturing process and thus reducing the manufacturing cost (for example, completing the manufacturing in a single injection molding process), and the fitting portion 140 can be easily fitted to the fitted portion 130 due to its material properties (deformable by compression). Preferably, the shape and dimensions of the fitting portion 140 correspond to the shape and dimensions of the fitted portion 130 (for example, the dimensions of the fitting portion 140 are equal to or greater than the dimensions of the fitted portion 130), and the fitting portion 140 is fitted to the fitted portion 130 to form a tight fit. That is, the fitting portion 140 with slightly larger or substantially equal dimensions is fitted to the fitted portion 130 by extrusion based on its material properties, and the outer surface of the fitting portion 140 is closely abutted 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.

[0030] Also, as an example, when a soft material such as a resin material is selected to manufacture the knob portion 110, the slider connection portion 120, the fitting portion 140, etc., as shown in FIGS. 1 to 4, a recessed portion 114 is formed at a site close to the first side S1 of the outer surface of the knob portion 110, and in the viewing angle when viewed from the front of the knob portion 110 (i.e., the viewing angles of FIGS. 2 and 4), the recessed portion 114 does not overlap with the region corresponding to the fitted portion 130 of the knob portion 110. With the above arrangement, as shown in FIG. 3, a recessed portion 114 is formed on the first side S1 of the knob portion 110, and a fitted portion 130 is formed on the second side S2. The thickness of the region corresponding to the recessed portion 114 on the first side S1 of the knob portion 110 (i.e., the distance d1 in the thickness direction T between the outer surfaces on both opposite sides of the recessed portion 114) is substantially equal to the thickness of the region corresponding to the fitted portion 130 on the second side S2 (i.e., obtained by subtracting the distance d3 in the thickness direction T between the inner walls on both opposite sides of the fitted portion 130 from the distance d2 in the thickness direction T between the outer surfaces on both opposite sides of the knob portion 110). Thus, in the process of manufacturing the fastener handle 100 by injection molding of the resin material, it is possible to avoid the surface recesses generated by the difference in the rates of thermal expansion and thermal contraction due to the difference in the thicknesses on both opposite sides of the knob portion 110, whereby the knob portion 110 of the fastener handle 100 has a beautiful appearance.

[0031] However, in the modification shown in FIG. 7, the fastener pull tab 100A has a structure arrangement similar to that of the aforementioned fastener pull tab 100, and the main difference is that the recessed portion 114 formed on the outer surface of the aforementioned knob portion 110 is not formed on the outer surface of the knob portion 110A. For the specific structures of the remaining slider connection portion 120, the fitted portion 130, and the fitting portion 140, reference may be made to the foregoing content, and detailed description will not be repeated here. As can be understood from this, in the present embodiment, in the method of manufacturing the fastener pull tab 100 by injection molding of a resin material, it is proposed to form the recessed portion 114 on the outer surface of the knob portion 110 to avoid the outer surface of the knob portion 110 from being recessed. However, when using a resin material, it is not necessary to form the recessed portion 114 on the outer surface of the knob portion 110. Alternatively, the fastener pull tab 100 may be manufactured using a material other than the resin material and / or a process other than injection molding. The present invention does not limit the presence or absence of the installation of the recessed portion 114, nor the type of material and manufacturing process of the fastener pull tab 100, and can be adjusted as needed.

[0032] In summary, in the puller for the fastener of the present invention, the slider connection part extends outward from the front end of the knob part, the part to be fitted is located on one side surface in the width direction of the knob part, and the fitting part extends outward from the end of the slider connection part. Among them, the slider connection part is suitable for passing through the handle attachment part of the fastener slider, and the fitting part fits into the part to be fitted along the side surface of the knob part to close the slider connection part to form an annular shape. In this way, the puller for the fastener can be manufactured using the same material, and can be attached and fixed by the combination of its own structure (i.e., the part to be fitted and the fitting part), so that it can be easily attached to the slider by opening and closing. In particular, the fitting part fits into the part to be fitted along the side surface of the knob part, and can provide a good connection effect between the fitting part and the part to be fitted, so that the puller for the fastener in the closed state is not easily loosened during use. Preferably, the extending recess of the part to be fitted extends from the front end to the rear end of the knob part along the side surface of the knob part, and the fitting recess of the part to be fitted is located at the rear end of the extending recess, thereby increasing the contact area between the fitting part and the part to be fitted that fit into each other, and improving the structural strength of the puller for the fastener. Therefore, the puller for the fastener of the present invention can reduce the manufacturing process and reduce the manufacturing cost, and has sufficient structural strength and good operability.

[0033] Finally, it should be noted that the above embodiments are only used for the description of the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can naturally understand that the technical solutions described in the above embodiments can still be modified, or equivalent replacements can be made for some or all of the technical features. However, these modifications or replacements do not deviate from the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
