Description

Technical Field

[0001] The present invention relates to the technical field of zippers, and in particular to a stopping component and a zipper. Background Art

[0002] A zipper usually includes two tapes, teeth arranged on opposite sides of the two tapes, and a slider for engaging and separating the teeth on both sides. Upper and lower stops are respectively arranged at both ends of the zipper to prevent the slider from detaching from the zipper. The lower stop has the function of preventing the slider from escaping from the zipper. However, in conventional zippers, since the teeth need to engage with each other, there is usually a space between the two tapes for the teeth to engage with each other, resulting in a gap between the left and right tapes at the upper and lower ends of the zipper. When the zipper is sewn onto clothing, the existence of the gap will cause problems with appearance and sealing.

[0003] Therefore, how to reduce the gap between the two cloth belts installed at the bottom stop is a technical problem that those skilled in the art need to solve at present. Summary of the invention

[0004] The object of the present invention is to provide a stopper component capable of reducing the gap between two cloth tapes on which the bottom stop is installed. Another object of the present invention is to provide a zipper including the stopper component.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A stopping component, comprising:

[0007] A main body is installed at the end of a tooth chain on a pair of cloth belts. The main body includes a receiving groove for compressing the cloth belt arranged on both sides thereof, and a movement between the two receiving grooves. The two receiving grooves are respectively provided with a first guide channel and a second guide channel on the side close to each other. The first guide channel and the second guide channel are respectively provided with a first entrance channel and a second entrance channel for the ribs at the edge of the cloth belt to enter at one end close to the tooth chain, and a first exit channel and a second exit channel are respectively provided at the other end. The first guide channel and the second guide channel are used to guide the two ribs to approach each other; the spacing between the first entrance channel and the second entrance channel is greater than the spacing between the first exit channel and the second exit channel.

[0008] Preferably, the two accommodating grooves and the first guide channel and the second guide channel are symmetrically arranged on both sides of the movement, and the first guide channel and the second guide channel are close to each other toward the corresponding first outlet channel and second outlet channel.

[0009] Preferably, the second guide channel is parallel to the extending direction of the tooth chain, and the direction in which the first guide channel extends toward the end of the first outlet channel is close to the second guide channel.

[0010] Preferably, the first guide channel and the second guide channel respectively include transition channels located between the first inlet channel and the first outlet channel and between the second inlet channel and the second outlet channel, and the two transition channels respectively connect the first inlet channel and the first outlet channel and the second inlet channel and the second outlet channel.

[0011] Preferably, the transition channel is an arc-shaped structure or a linear structure as a whole.

[0012] Preferably, the main body is formed by integral injection molding or by metal riveting.

[0013] A zipper, comprising the above-mentioned stopper component, further comprising:

[0014] A pair of cloth straps;

[0015] Tooth chains are respectively arranged on opposite sides of the fabric belt;

[0016] A puller used to move forward or backward along a toothed chain to engage or disengage the toothed chain.

[0017] With respect to the above-mentioned background technology, a stopping component provided by the present invention includes a main body and a tooth chain end portion installed on a pair of cloth belts. The main body includes a receiving groove for compressing the cloth belt arranged on both sides thereof, and a movement between the two receiving grooves. A first guide channel and a second guide channel are respectively arranged on the side where the two receiving grooves are close to each other. The first guide channel and the second guide channel are respectively arranged at one end close to the tooth chain for the belt ribs at the edge of the cloth belt to enter, and a first exit channel and a second exit channel are respectively arranged at the other end. The first guide channel and the second guide channel are used to guide the two belt ribs to approach each other; the spacing between the first entrance channel and the second entrance channel is greater than the spacing between the first exit channel and the second exit channel.

[0018] Specifically, a toothed chain is installed on one side opposite to the other of the two cloth belts, and a stopping component is installed at the end position of the two toothed chains, which is also the position between the two cloth belts. The stopping component is used to limit the pull head from exceeding the travel range of the toothed chain; and the stopping component includes a main body, and two accommodating grooves are arranged inside the main body, and the innermost sides of the two accommodating grooves are respectively provided with a first guide channel and a second guide channel; the two accommodating grooves can press the cloth belts on both sides, and a belt rib is arranged at the edge of the cloth belt, so that the belt rib can pass through the first guide channel and the second guide channel respectively; that is to say, the left cloth belt is pressed tightly on the main In the receiving groove on the left side of the body, the ribs of the left cloth tape enter through the first entrance channel and extend from the first exit channel, while the right cloth tape is pressed tightly in the receiving groove on the right side. Similarly, the ribs of the right cloth tape enter from the second entrance channel and extend from the second exit channel, thereby completing the installation of the stopper component; but it should be noted that the first guide channel and the second guide channel have the function of guiding the ribs to approach each other during the process from the entrance to the exit. In other words, after the ribs of the two cloth tapes are guided by the first guide channel and the second guide channel, when they extend from the exit, the gap between the two ribs will be greatly reduced. With this arrangement, the gap between the two cloth tapes caused by the tooth chain can be minimized by the stopper component, thereby increasing the overall aesthetics of the zipper using the stopper component.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0035] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by terms such as “upper”, “lower”, “front”, “backward”, “left” and “right” are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the positions or elements referred to must have a specific direction, be constructed and operate in a specific direction. Therefore, they should not be understood as limitations of the present invention.

[0036] The object of the present invention is to provide a stopping component capable of reducing the gap between two cloth belts installed with a lower stop.

[0037] To achieve the above object, the present invention provides the following technical solutions:

[0038] See also Figures 1 to 3 The present embodiment provides a stopping component, including a main body 1, and an end portion of a toothed chain 02 installed on a pair of cloth tapes 01. The main body 1 includes a receiving groove 11 for pressing the cloth tape 01 arranged on both sides thereof, and a movement 12 between the two receiving grooves 11. The two receiving grooves 11 are respectively provided with a first guide channel 13 and a second guide channel 14 on the side close to each other. The first guide channel 13 and the second guide channel 14 are respectively provided with a first entrance channel 131 and a second entrance channel 141 at one end close to the toothed chain 02 for the ribs 03 at the edge of the cloth tape 01 to enter, and a first exit channel 132 and a second exit channel 142 at the other end. The first guide channel 13 and the second guide channel 14 are respectively provided with a first exit channel 132 and a second exit channel 142. The first guide channel 13 and the second guide channel 14 are used to guide the two ribs 03 to approach each other; the spacing between the first entrance channel 131 and the second entrance channel 141 is greater than the spacing between the first exit channel 132 and the second exit channel 142.

[0039] Specifically, a toothed chain 02 is installed on the opposite side of the two cloth tapes 01, and a stopping component is installed at the end position of the two toothed chains 02, which is also the position between the two cloth tapes 01. The stopping component is used to limit the slider 04 from exceeding the travel range of the toothed chain 02; and the stopping component includes a main body 1, and two accommodating grooves 11 are arranged inside the main body 1, and the innermost sides of the two accommodating grooves 11 are respectively provided with a first guide channel 13 and a second guide channel 14; the two accommodating grooves 11 can press the cloth tapes 01 on both sides, and a rib 03 is arranged at the edge of the cloth tape 01, so that the rib 03 can pass through the first guide channel 13 and the second guide channel 14 respectively.

[0040] That is, the left side cloth belt 01 is pressed tightly in the receiving groove 11 on the left side of the main body 1, and the ribs 03 of the left side cloth belt 01 enter through the first entrance channel 131 and extend from the first exit channel 132, while the right side cloth belt 01 is pressed tightly in the right side receiving groove 11. Similarly, the ribs 03 of the right side cloth belt 01 enter through the second entrance channel 141 and extend from the second exit channel 142, thereby completing the installation of the stopper. However, it should be noted that the first guide channel 13 and the second guide channel 14 have the function of guiding the ribs 03 to approach each other during the process from the entrance to the exit, and in this embodiment, the spacing between the first entrance channel 131 and the second entrance channel 141 is greater than the spacing between the first exit channel 132 and the second exit channel 142. In other words, after the ribs 03 of the two cloth belts 01 are guided through the paths of the first guide channel 13 and the second guide channel 14, when they extend from the exit, the gap between the two ribs 03 will be greatly reduced.

[0041] In one embodiment, the first guide channel 13 is inclined from the left side of the main body 1 toward the movement 12 in the middle of the main body 1, and the second guide channel 14 is inclined from the right side of the main body 1 toward the movement 12 in the middle of the main body 1, so that the second guide channel 14 guides the end of the cloth belt 01 entering the main body 1 to bend, so that the end of the cloth belt 01 can be close to the other side of the cloth belt 01, and finally the ribs 03 will return from the first outlet channel 132 and the second outlet channel 142, so that the end of the cloth belt 01 located outside the blocking component is maintained in a certain direction range, and the gap between the two cloth belts 01 is stabilized. The first guide channel 13 and the second guide channel 14 can both effectively limit the movement of the cloth belt 01 while guiding the extension trajectory of the ribs 03 at the side edge of the end of the cloth belt 01, so that the cloth belt 01 can stably maintain a specific movement trajectory. That is to say, by changing the positions of the first inlet channel 131 and the second inlet channel 141, the first outlet channel 132 and the second outlet channel 142, the starting point and the end point of the rib 03 at the side edge of the cloth tape 01 on the main body 1 are determined, so that the position and the bending angle of the cloth tape 01 can be determined within a certain range, and the angle of the cloth tape 01 after extending out of the main body 1 is controlled by the direction of the first outlet channel 132 and the second outlet channel 142 so that the cloth tape 01 can approach the cloth tape 01 on the other side at the expected inclination angle.

[0042] With such arrangement, the gap between the two fabric tapes 01 caused by the tooth chain 02 can be minimized by the stopping component, thereby increasing the overall aesthetics of the zipper using the stopping component.

[0043] Moreover, in the present application, the stopper can be located at the upper end of the cloth tape 01 or at the lower end of the cloth tape 01, i.e., the upper stop or lower stop of the zipper. When the stopper is a lower stop, a fitting portion is provided on the upper surface of the main body 1 of the stopper, which fits with the shape of the lowest teeth of the cloth tape 01 on the same side, and the guide channel on this side can also be adapted to extend to the fitting portion. While the fitting portion reduces the gap between the stopper and the teeth, the entrance channel of the guide channel is opened on the upper surface of the fitting portion, which can also ensure that part of the side edge of the cloth tape 01 can still effectively enter the main body 1, and the fitting portion will not interfere with the interaction between the cloth tape 01 and the main body 1. When the stopper is an upper stop, the principle is similar, except that the position of the fitting portion changes up and down.

[0044] Furthermore, as the bending of the adjacent sides of the cloth belt 01 changes, the edges of the two cloth belts 01 on the side away from each other are simultaneously contracted and bent inward, that is, when the end of the cloth belt 01 is not in a bent state, the cloth belt 01 itself is an ordinary cloth belt 01 with a vertical head. The cloth belt 01 can be produced according to a conventional production method, and there is no need to specially produce the cloth belt 01 with a bent end. It is only necessary to keep the end of the cloth belt 01 in a bent state when installing the stopping component, thereby saving production costs and efficiency.

[0045] Preferably, the two accommodating grooves 11 and the first guide channel 13 and the second guide channel 14 are symmetrically arranged on both sides of the movement 12, and the first guide channel 13 and the second guide channel 14 are close to each other toward the corresponding first outlet channel 132 and the second outlet channel 142.

[0046] Specifically, the two receiving grooves 11 are symmetrically arranged with respect to the movement 12, and the first guide channel 13 and the second guide channel 14 are also symmetrical with respect to the movement 12; that is, the first inlet channel 131 and the second inlet channel 141, the first outlet channel 132 and the second outlet channel 142 are also symmetrical with respect to the movement 12; but it should be noted that the distance between the first inlet channel 131 and the second inlet channel 141 is greater than the distance between the first outlet channel 132 and the second outlet channel 142; the distance between the first inlet channel 131 and the second inlet channel 141 needs to meet the space for the toothed chain 02 to mesh, but the distance between the first outlet channel 132 and the second outlet channel 142 needs to be reduced to guide the gap between the two protruding ribs 03. Among them, the distance between the first outlet channel 132 and the second outlet channel 142 can be adjusted according to actual conditions, but the two are preferably arranged to fit each other.

[0047] Preferably, the second guide channel 14 is parallel to the extension direction of the toothed chain 02 , and the direction in which the first guide channel 13 extends toward the end of the first outlet channel 132 is close to the second guide channel 14 .

[0048] There are usually two channels for the stopper to cooperate with the ribs 03 of the cloth belt 01 and they are arranged on the left and right sides of the main body 1 to cooperate with the left and right cloth belts 01 , wherein the number of the bent guide channels can be one or two.

[0049] In one embodiment, specifically Figure 4 As shown, there is only one bent limiting channel, and the other guiding channel in the main body 1 cooperating with the cloth belt 01 is a conventional vertical channel. Specifically, the curved left side is the first guiding channel 13, and the vertical right side is the second guiding channel 14. The second guiding channel 14 is only used to ensure that the blocking component can be effectively connected to the cloth belt 01. At this time, the bending angle of the first guiding channel 13 to the cloth belt 01 needs to be larger, that is, the bending angle of the transition channel 15 in the first guiding channel 13 is larger, and the gap between the cloth belts 01 is closer to the cloth belt 01 on the other side; such an arrangement can also reduce the gap between the two cloth belts 01.

[0050] Preferably, the first guide channel 13 and the second guide channel 14 respectively include a transition channel 15 located between the first inlet channel 131 and the first outlet channel 132, and between the second inlet channel 141 and the second outlet channel 142, and the two transition channels 15 respectively connect the first inlet channel 131 and the first outlet channel 132, and the second inlet channel 141 and the second outlet channel 142.

[0051] That is, the first guide channel 13 and the second guide channel 14 further include a transition channel 15, which is specifically an inclined section channel connecting the first inlet channel 131 and the first outlet channel 132, the second inlet channel 141 and the second outlet channel 142. Figure 2 and Figure 3 As shown, the lower end of the transition channel 15 is closer to the middle of the movement 12 than the upper end.

[0052] In one embodiment, the first entrance channel 131 and the second entrance channel 141 are both vertically arranged, that is, the axes of the two are parallel to the extension direction of the tooth chain 02. Such an arrangement can facilitate the insertion of the ribs 03 of the cloth belt 01 into the first entrance channel 131 and the second entrance channel 141; and the setting of the transition channel 15 can make the cloth belt 01 transition to the exit more smoothly after bending, so that the bending of the end of the cloth belt 01 is more natural and not prone to excessive twisting.

[0053] Preferably, the transition channel 15 is an arc-shaped structure or a linear structure as a whole.

[0054] Furthermore, the overall shape of the transition channel 15 may also be an arc, that is, the first inlet channel 131 and the first outlet channel 132 are smoothly connected, which is conducive to the insertion of the rib 03; the transition channel 15 may also select a straight line or a broken line structure according to actual conditions, which is not limited in this article.

[0055] In one embodiment, the axes of the first inlet channel 131 and the first outlet channel 1132 coincide with each other, and the axes of the second inlet channel 141 and the second outlet channel 142 coincide with each other.

[0056] That is to say, the first guide channel 13 and the second guide channel 14 are both straight inclined channels, that is, the axes of the first inlet channel 131 and the first outlet channel 132 coincide with each other, and the axes of the second inlet channel 141 and the second outlet channel 142 coincide with each other. Figure 5 As shown, in this way, the ribs 03 of the tape 01 will directly pass through the first guide channel 13 and the second guide channel 14 .

[0057] In general, the two guide channels can be symmetrically arranged on the left and right sides of the main body 1, and can also be appropriately offset or changed in direction, angle, length, width, diameter, etc. as needed.

[0058] In one embodiment, the main body 1 as a whole can be a U-shaped structure.

[0059] Specific as Figure 6 As shown; the main body 1 also includes a core 12, which is located between the two guide channels and the receiving groove 11, and is used to separate the two guide channels and the cloth tapes 01 of the receiving groove 11, so that the two cloth tapes 01 will not interfere with each other in the main body 1 and affect the effect of reducing the gap between the cloth tapes 01. The shape of the core 12 is also adapted to the shape of the guide channels on both sides, and the width gradually decreases from the upper surface to the lower surface of the main body 1.

[0060] In addition, in this embodiment, the transition channel 15 in the middle of the first guide channel 13 and the second guide channel 14 can be an arc-shaped structure or a linear structure.

[0061] Of course, the overall shape of the main body 1 can be adjusted according to actual conditions, and this article does not make any specific restrictions here.

[0062] Optionally, the first outlet channel 132 and the second outlet channel 142 are axially parallel to the extension direction of the toothed chain 02 .

[0063] That is to say, as an option, the first outlet channel 132 and the second outlet channel 142 can be placed close to each other while the axes are parallel to each other. This arrangement can ensure that the extended ribs 03 can remain parallel to each other. Figure 3 , Fig. 9 and Fig.10 As shown; such an arrangement can ensure the overall aesthetics of the zipper.

[0064] Optionally, the axes of the first outlet channel 132 and the second outlet channel 142 intersect each other in a direction away from the toothed chain 02 .

[0065] Specifically, as an option, the axes of the first outlet channel 132 and the second outlet channel 142 are close to each other in the downward direction, that is, the two are crossed together downward, so that the cloth belt 01 passing through the blocking component will overlap. Figure 7 shown.

[0066] Optionally, the axes of the first outlet channel 132 and the second outlet channel 142 move away from each other in a direction away from the toothed chain 02 .

[0067] As an option, the axes of the first outlet channel 132 and the second outlet channel 142 are away from each other in the downward direction, that is, they gradually diverge downward, so that the cloth belt 01 passing through the stopper component will be bifurcated. Figure 8 shown.

[0068] In general, the inclination angle of the first outlet channel 132 and the second outlet channel 142 relative to the length direction of the cloth tape 01 is preferably between -15 degrees and 15 degrees, that is, the extension directions of the outlet channel axes of the second guide parts of the left and right guide channels can be gradually away from each other, parallel or crossed. Figure 8 As shown, in the gradually moving away state, the lower belt head forks to the left and right, the upper gap of the belt head gap is smaller, and the lower gap is larger. After the zipper is sewn onto the clothing, the gap of the exposed part of the end of the tape 01 is still small. Figure 3 , Fig. 9 and Fig.10 As shown, in the parallel state, the lower cloth belt 01 is parallel to the left and right, and the gap size is the distance between the two guide channel exits. The closer the distance, the smaller the gap. Figure 7 As shown, in the crossed state, the two lower tape heads will cross each other, and the left and right tapes 01 will overlap with each other, with basically no gap or only a small gap at the contact outlet. In this embodiment, the outlet channels of the two guide channels are preferably parallel, and the side edges of the left and right tapes 01 are in contact with each other, so as to achieve no gap between the ends of the zipper tapes 01.

[0069] Preferably, the main body is formed by integral injection molding or by metal riveting.

[0070] In addition, in this embodiment, the stopper is an integral structure, and its material can be an injection molding material or a metal material. When the stopper is an injection molding material, the stopper is formed on the cloth belt 01 by injection molding, and the stopper after injection molding and cooling restricts the bending and approaching state of the ribs 03 of the cloth belt 01, maintaining a gapless or gap-reduced state, making the processing more convenient and more efficient. When the stopper is a metal material, the stopper is first formed, and then the stopper bites the cloth belt 01, so that the cloth belt 01 maintains a state of extending along the guide channel in the metal stopper, achieving a gapless or gap-reduced state of the cloth belt 01, making the processing more flexible, and the stopper is also easy to replace and repair.

[0071] This article also provides a zipper, including the stopping component mentioned above, and also includes: a pair of cloth tapes 01, a tooth chain 02 respectively arranged on the opposite side of the cloth tapes 01, and a slider 04 used to move forward or backward along the tooth chain 02 to engage or separate the tooth chain 02; and the zipper has all the beneficial effects of the stopping component described above.
