Description

Technical Field

[0001] This invention relates to the field of zipper technology, and more particularly to a concealed zipper pull and zipper with a detachable and replaceable zipper tab. Background Technology

[0002] Invisible zippers are an important component of garment accessories. A typical open zipper consists of teeth, fabric tape, top stop, bottom stop, zipper pull base, and pull tab. Currently, invisible zippers are widely used in various garment categories and styles. The zipper pull is the component on the zipper that facilitates the opening and closing of the teeth, while the pull tab on the zipper pull provides a convenient grip for easy movement and serves an aesthetic purpose. During daily use, the pull tab, especially the connecting part, is prone to damage and paint chipping, affecting its appearance. Therefore, it is necessary to allow for DIY zipper pull replacement and to meet the market demand for personalized zipper tab replacements.

[0003] Existing zipper pull and tab assembly methods are complex and require specialized tools. Without violent damage, clothing consumers cannot manually disassemble the zipper pull cap and hook to replace the zipper pull. Currently, zipper pulls with replaceable tabs are achieved by adding a torsion spring to the zipper pull cap and creating an opening at the cap's crossbar to allow for the replacement of the tab and zipper pull assembly. This method results in complex assembly and product structure, leading to low production efficiency and capacity.

[0004] For those skilled in the art, how to achieve detachable and replaceable pull tabs is a technical problem that needs to be solved. Summary of the Invention

[0005] The core of this invention lies in providing a removable and replaceable concealed pull tab. The connecting channel on the hook allows the pull tab to be pulled normally while also raising the limiting tip for pull tab replacement. The specific solution is as follows:

[0006] A removable, replaceable pull tab concealed zipper head, including a zipper head base, a hook, and a connecting pin;

[0007] The hook is provided with a connecting channel, a locking hook and a limiting tip; the connecting pin passes through the connecting channel to slide the hook to the pull head base.

[0008] The connecting channel has an angle along its length extension direction. The first end of the connecting channel is the replacement end, and the last end is the assembly end. When the connecting pin is located at the assembly end of the connecting channel, the hook and the zipper base form a closed loop to install the zipper pull. When the hook is not pulled by the zipper pull, the limiting tip can abut against the teeth of the zipper to prevent the zipper base from moving in the direction of tooth separation. When the zipper pull causes the limiting tip to rise so that the locking hook hooks onto the zipper base, the limiting tip separates from the teeth to allow the zipper base to move in the direction of tooth separation.

[0009] When the connecting pin is located at the replacement end of the connecting channel, the locking hook separates from the pull head base to release the obstruction, and the pull tab can drive the limiting tip to rise, so as to realize the replacement of the pull tab.

[0010] Optionally, the locking hook is disposed at the head end of the hook, and the limiting tip is disposed at the tail end of the hook;

[0011] The pull head base has a front locking block at the head end for engaging with the locking hook for locking.

[0012] Optionally, the pull head base is provided with a retaining wall for limiting the hook from both sides, and the connecting pin is installed on the retaining wall.

[0013] Optionally, the tail end of the baffle protrudes towards the hook and is provided with a protrusion, the protrusion and the inner edge of the limiting tip forming a closed loop for installing the pull tab.

[0014] Optionally, a blocking hook is provided on the inner edge of the limiting tip, and the inner edge of the blocking hook and the upper base plate of the pull head base form a closed loop for installing the pull tab.

[0015] Optionally, the width of the baffle wall gradually decreases from the beginning to the end.

[0016] Optionally, the inner edges of the beginning and end of the connecting channel are respectively set to arc shape.

[0017] Optionally, the bend angle of the connecting channel is set to 60°-150°.

[0018] Optionally, the baffle wall is provided with an avoidance groove, which is used to ensure that both ends of the connecting pin are flush with the outer surface of the baffle wall when the connecting pin is installed.

[0019] The present invention also provides a zipper including a concealed zipper pull with a detachable and replaceable zipper tab as described in any of the preceding claims.

[0020] This invention provides a removable, replaceable pull tab concealed zipper pull. A connecting pin passes through a connecting channel to slidably connect a hook to the zipper pull base. The connecting channel has an angle along its length. When the connecting pin is at the assembly end of the connecting channel, the hook and the zipper pull base form a closed loop to install the pull tab, ensuring the pull tab cannot be separated. When the hook is not pulled by the pull tab, the limiting tip can abut against the zipper teeth to prevent the zipper pull base from moving in the direction of tooth separation. When the pull tab causes the limiting tip to rise, allowing the locking hook to engage with the zipper pull base, the limiting tip separates from the teeth, allowing the zipper pull base to move in the direction of tooth separation. When the connecting pin is at the replacement end of the connecting channel, the locking hook separates from the zipper pull base, releasing the obstruction, and the pull tab can cause the limiting tip to rise, thus enabling the pull tab to be replaced.

[0035] The image includes:

[0036] Pull head base 1, front locking block 11, baffle 12, protrusion 121, avoidance groove 122, hook 2, connecting channel 21, locking hook 22, limit tip 23, blocking hook 231, connecting pin 3, pull tab 4. Detailed Implementation

[0037] This invention provides a removable and replaceable concealed pull tab. The connecting channel on the hook can both keep the pull tab moving normally and raise the limiting tip to replace the pull tab.

[0038] To enable those skilled in the art to better understand the technical solution of the present invention, the following will provide a detailed description of the removable and replaceable pull tab concealed zipper pull of the present invention in conjunction with the accompanying drawings and specific embodiments.

[0039] Combination Figure 1 , Figure 2 As shown, this invention provides a removable, replaceable concealed zipper pull, including a zipper pull base 1, a hook 2, and a connecting pin 3, etc.; combined with Figure 3 , Figure 4 , Figure 5 As shown, the hook 2 is provided with a connecting channel 21, a locking hook 22 and a limiting tip 23; the locking hook 22 is located at the head end of the hook 2, the limiting tip 23 is located at the tail end of the hook 2, and the connecting channel 21 is located in the middle part of the hook 2.

[0040] The connecting pin 3 passes through the connecting channel 21 to slidably connect the hook 2 to the slider base 1. The connecting pin 3 is fixed relative to the slider base 1 or can rotate about its axis. The connecting pin 3 can slide along the length of the connecting channel 21 and can rotate relative to the connecting channel 21. The movement path of the connecting pin 3 along the connecting channel 21 is as follows: Figure 4 , Figure 5 The dotted line shown.

[0041] The connecting channel 21 has a bend in its length extension direction, and the connecting pin 3's movement path along the connecting channel 21 approximates the bend. The head end of the connecting channel 21 ( Figure 4 The left end is the replacement end, and the tail end is... Figure 4 The right end is the assembly end.

[0042] Combination Figure 8 , Figure 9 As shown, when the connecting pin 3 is located at the assembly end of the connecting channel 21, the hook 2 and the pull head base 1 form a closed loop to install the pull tab 4. At this time, the pull tab 4 remains in normal use and cannot detach from the closed loop space formed by the hook 2 and the pull head base 1. Figure 8As shown, when the hook 2 is not pulled by the pull tab 4, the limiting tip 23 can abut against the top of the zipper teeth to prevent the zipper head base 1 from moving in the direction of tooth separation, thus preventing the zipper head from slipping. At this time, the locking hook 22 is not in contact with the zipper head base 1. Figure 9 As shown, when the pull tab 4 drives the limiting tip 23 to rise so that the locking hook 22 hooks onto the pull head base 1, the limiting tip 23 rises slightly upward and separates from the teeth so that the pull head base 1 can move in the direction of the teeth separation to unlock; at this time, the locking hook 22 contacts the pull head base 1 and limits the maximum height of the upward rise of the limiting tip 23.

[0043] Combination Figure 12 , Figure 13 As shown, when the connecting pin 3 is at the replacement end of the connecting channel 21, the hook 2 moves from... Figure 8 The state shown moves a distance to the right. At this time, the locking hook 22 and the pull head base 1 separate laterally to release the obstruction. When the pull tab 4 drives the limit tip 23 to rise, a gap is formed between the limit tip 23 and the pull head base 1 to realize the replacement of the pull tab 4. Figure 13 The upward movement of the limit tip 23 shown is greater than Figure 9 The extent to which the limiting tip 23 rises upwards is shown. Figure 9 The limiting tip 23 still forms a closed loop with the pull head base 1, blocking the pull tab 4. Figure 13 The limiting tip 23 is separated from the pull head base 1, allowing the pull tab 4 to be freely replaced. After replacement, the hook 2 is moved back to the assembly position of the connecting pin 3, and it can be used normally.

[0044] The present invention uses the connecting channel 21, locking hook 22, and limiting tip 23 provided on the hook 2 to cooperate with the pull head base 1 and connecting pin 3, so as to ensure that the hook 2 can play the role of locking the pull head, and can also easily and quickly replace the pull tab 4.

[0045] Combination Figure 4 As shown, the left end is the head end, and the right end is the tail end. The locking hook 22 is located at the head end of the hook 2, and the limiting tip 23 is located at the tail end of the hook 2. The locking hook 22 is a downward-bending hook structure located at the head end of the hook 2. The limiting tip 23 is a downward-bending hook structure located at the tail end of the hook 2. The size of the limiting tip 23 is larger than the size of the locking hook 22, and the downward extension of the limiting tip 23 is greater than the downward extension of the locking hook 22.

[0046] Combination Figure 6 , Figure 7 As shown, the zipper base 1 has a front locking block 11 at the head end for locking in conjunction with the locking hook 22. The front locking block 11 is a wall structure that is perpendicular to the upper surface of the zipper base 1 and extends upward. The locking hook 22 can be engaged with the upper edge of the front locking block 11.

[0047] Combination Figure 6 , Figure 7 As shown, the pull head base 1 is provided with baffles 12 for limiting the hooks 2 from both sides. The connecting pin 3 is installed on the baffles 12. The baffles 12 are provided with through holes for the connecting pin 3 to pass through, so that the connecting pin 3 can be fixed or rotated to the baffles 12. The front locking block 11 can be fixed relative to the two baffles 12 and is located between the two baffles 12.

[0048] Combination Figure 6 , Figure 7 As shown, the tail end of the baffle 12 protrudes towards the hook 2 with a protrusion 121. The protrusion 121 is an upwardly protruding bump structure. The protrusion 121 and the inner edge of the limiting tip 23 form a closed loop for mounting the pull tab 4. The structure in which the inner edge of the protrusion 121 and the inner edge of the limiting tip 23 form a closed loop is as follows: Figure 8 , Figure 9 As shown, in normal use, when the limiting tip 23 is raised upward to release the locking stop with the tooth, the limiting tip 23 will not completely disengage from the protrusion 121 in the vertical direction, thus playing the role of the limiting pull tab 4.

[0049] Combination Figure 5 As shown, in another embodiment, a blocking hook 231 is provided on the inner edge of the limiting tip 23. The inner edge of the blocking hook 231 and the upper base plate of the pull head base 1 form a closed loop for installing the pull tab 4. The blocking hook 231 mainly cooperates with the pull tab 4 to bear the pulling force. At this time, the protrusion 121 can be omitted or a protrusion 121 with a low protrusion amplitude can be provided on the pull head base 1.

[0050] Furthermore, combining Figure 6 , Figure 7 As shown, the width of the baffle 12 gradually decreases from the beginning to the end, thus guiding the chain teeth on the fabric belt.

[0051] Combination Figure 3 , Figure 4 , Figure 5 As shown, the inner edges of the beginning and end of the connecting channel 21 are respectively set as arcs, thus matching the outer surface of the connecting pin 3, allowing the connecting pin 3 to rotate relative to it. When the limiting tip 23 is lifted upward, the hook 2 can rotate relative to the connecting pin 3. Figure 4 As shown, the radius of the arc at the right end of the connecting channel 21 can be slightly larger than the radius of the arc at the left end, ensuring that the limit tip 23 can be flexibly raised during normal use.

[0052] Specifically, the bend angle of the connecting channel 21 is set to 60°-150°, with a bend in the middle. When the hook 2 is pulled laterally by the pull tab 4, it is blocked by the inner surface of the inclined surface of the connecting channel 21, ensuring that the connecting pin 3 will not move freely within the connecting channel 21, thus preventing the hook 2 from being accidentally unlocked. Unlocking can only be done by following the... Figure 10 , Figure 11 , Figure 12 You can only unlock it by moving in the direction indicated by the arrow.

[0053] like Figure 12 , Figure 13 Move the hook position in the direction of arrow ① until the connecting pin 3 is at the left end of the connecting channel 21. The hook 2 is in an unlocked state, disengaged from the pull head base 1, to replace the pull tab 4. Arrow ④ indicates that the hook 2 can be opened towards the limiting tip 23 at the rear of the movement, forming a larger open space, allowing the pull tab 4 to be removed from the hook position for replacement. The replacement method is shown in arrows ② and ③.

[0054] Combination Figure 2 , Figure 6 As shown, the baffle 12 is provided with an avoidance groove 122. The avoidance groove 122 is used to make the two ends of the connecting pin 3 flush with the outer surface of the baffle 12 when it is installed. The two ends of the connecting pin 3 adopt a riveting structure to prevent the two ends of the connecting pin 3 from protruding from the outer surface of the baffle 12, so that the outer surface is flat.

[0055] The present invention also provides a zipper with a concealed zipper pull including any of the above-mentioned detachable and replaceable zipper tabs, which can achieve the above-mentioned technical effects.

[0056] The small protruding hook at the front end of hook 2 forms a locking hook 22, which mainly hooks onto the front baffle 12 of the zipper base, fixing the position of hook 2 and preventing it from detaching from the zipper base 1 when the zipper 4 is lifted. The back of hook 2 has a gentle curve and an extended slope, making the curve of the rear limiting tip 23 of hook 3 gentler and the slope longer, thereby increasing the open space of hook 2 and making it easier to open.

[0057] The inner edge of the limiting tip 23 has a gentle slope, which facilitates the replacement of the pull tab 4 and reduces wear on the surface of the pull tab 4. This, combined with the inner edge of the limiting tip 23, increases the clearance space at the rear end of the pull head.

[0058] The hollow design of the connecting channel 21 is the movement space of the connecting pin 3 inside the hook 2. The turning angle is relatively large. The connecting channel 21 is equipped with two inclined sliding tracks that can be connected to the connecting pin 3.

[0059] When connecting pin 3 is located Figure 4 The right end is the locking position of hook 2 during normal use. When connecting pin 3 is in the position... Figure 4The left end is the locking position after the hook 2 slides over when the pull tab 4 needs to be replaced. The connecting channel 21 is the main position where the connecting pin 3 contacts the hook 2 during use. It has an undulating zigzag shape. By lifting the hook at a specific angle, the pull tab can be replaced.

[0060] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
