Description

Technical Field

[0001] This utility model relates to the field of zipper technology, and in particular to a stop structure, an automatic opening structure, and a zipper. Background Technology

[0002] Conventional clothing and bags typically use zippers, buttons, or clasps to close the openings. However, these openings often have limited size, requiring the user to use both hands to widen them. This is inconvenient when retrieving or placing larger items, especially for the elderly or in emergencies. Furthermore, some garments, such as outdoor clothing, have fabric edges that tend to stick together due to the material's properties, resulting in poor breathability of the opening. To increase the opening's width, existing zippers incorporate a widening device. Existing technology discloses an automatic widening device and zipper that allows the zipper opening to be significantly enlarged.

[0003] However, the automatic opening device in the aforementioned zipper uses a cloth strip to cover the stop to prevent the opening component from being exposed, which affects the zipper's appearance. Furthermore, the cloth strip is prone to curling and instability during use, making it easy for the opening component to be exposed. Therefore, a stop structure, an automatic opening structure, and a zipper are proposed to address these problems. Utility Model Content

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0040] like Figure 1 As shown, to achieve the above objectives, this utility model provides a stop structure, including: a stop member 100 disposed on a fabric tape 400. When the zipper is placed vertically, the stop member 100 is specifically located at the upper and lower ends of the fabric tape 400. An installation channel 110 is provided inside the stop member 100. The installation channel 110 is integrally formed in the stop member 100. The installation channel 110 includes a bending portion 111 and guide portions 112 disposed at both ends of the bending portion 111. The bending portion 111 is used to embed the embedded section 210 of the supporting component 200, and the guide portion 112 is used to embed the supporting section 220 of the supporting component 200. By embedding the embedded section 210 of the supporting component 200 and the partial supporting sections 220 at both ends of the embedded section 210 in the installation channel 110, the supporting component 200 is stably limited, so that the supporting component 200 can maintain a certain shape for a long time, thereby playing a stable supporting role.

[0041] It should be noted that by embedding the embedded section 210 of the stretching component 200 into the bend of the installation channel 110, the protection and concealment of the stop component 100 are better than using a cloth strip to cover the stop component 100, effectively improving the overall aesthetics of the zipper; moreover, there is no risk of lifting, making the concealment effect of the stretching component 200 more stable, and it will not cause bumps or obstacles when the user pulls the zipper or touches the zippered clothing, thus providing better protection for the zipper and the user.

[0042] like Figure 2 As shown, in the second embodiment of this utility model, the installation channel 110 is U-shaped, and both guide portions 112 extend to the end face of the stop member 100 facing the chain tooth 500, so that the part of the supporting section 220 of the spreading member 200 extending out of the guide portion 112 can be inserted into the chain tooth 500. At this time, the chain tooth 500 is preferably a spiral chain tooth 500, and the part of the supporting section 220 of the spreading member 200 extending out of the guide portion 112 is inserted into the hollow in the middle of the chain tooth 500, and the part of the supporting section 220 of the spreading member 200 extending out of the guide portion 112 bends outward in its natural state. When the zipper is closed, at least one of the two support sections 220 extends out of the guide portion 112 and remains on the zipper tooth 500 in a state of bearing the squeezing force along the width direction of the zipper. When the zipper is opened, at least one of the two support sections 220 extends out of the guide portion 112 and, under its own elasticity, drives one of the fabric strips 400 away from the other fabric strip 400, so that the zipper opens to a preset size opening.

[0043] like Figure 3 As shown, in the third embodiment of this utility model, the installation channel 110 is V-shaped, and both guide portions 112 extend to the end face of the stop member 100 facing the chain tooth 500. Similarly, the part of the supporting section 220 of the spreading member 200 extending out of the guide portion 112 can be inserted into the chain tooth 500. At this time, the chain tooth 500 is preferably a spiral chain tooth 500, and the part of the supporting section 220 of the spreading member 200 extending out of the guide portion 112 is inserted into the hollow in the middle of the chain tooth 500. The part of the supporting section 220 of the spreading member 200 extending out of the guide portion 112 bends outward in its natural state or is consistent with the extension direction of the guide portion 112. When the zipper is closed, at least one of the two support sections 220 extends out of the guide portion 112 and remains on the zipper tooth 500 in a state of bearing the squeezing force along the width direction of the zipper. When the zipper is opened, at least one of the two support sections 220 extends out of the guide portion 112 and, under its own elasticity, drives one of the fabric strips 400 away from the other fabric strip 400, so that the zipper opens to a preset size opening.

[0044] like Figure 4As shown, in the fourth embodiment of this utility model, the mounting channel 110 is generally V-shaped, and both guide portions 112 extend to the two sides of the stop member 100 along the width direction of the fabric tape 400. At this time, the portion of the supporting section 220 of the spreading member 200 extending out of the guide portion 112 is sewn to the fabric tape 400 or integrally formed on the fabric tape 400. The chain tooth 500 can be a spiral chain tooth 500 or a solid chain tooth 500. The portion of the supporting section 220 of the spreading member 200 extending out of the guide portion 112 is bent outward in its natural state or is consistent with the extension direction of the guide portion 112. When the zipper is closed, at least one portion of the two supporting sections 220 extending out of the guide portion 112 is held on the fabric tape 400 in a state of bearing the squeezing force along the width direction of the zipper. When the zipper is opened, at least one portion of the two supporting sections 220 extending out of the guide portion 112 drives one of the fabric tapes 400 away from the other fabric tape 400 under its own elasticity, so that the zipper opens to a preset size opening.

[0045] like Figure 5 As shown, in some specific embodiments, the bending portion 111 is cylindrical in shape. In this case, the embedded section 210 of the expanding component 200 is set as a spiral shape. Specifically, the embedded section 210 is a spring shape with a certain bending angle. The spiral embedded section 210, through its multi-turn deformation structure, can provide a more flexible and greater elastic stroke, improving the smoothness and cushioning effect of the overall opening and closing action of the expanding component 200. Moreover, it has better fatigue resistance and will not be easily damaged during long-term repeated bending, effectively extending the service life of the automatic expanding structure. Of course, on the basis of ensuring that the embedded section 210 has sufficient elastic stroke, the embedded section 210 can also be a simple bending shape. A simple bending shape makes the processing and manufacturing of the embedded section 210 easier.

[0046] It should be noted that by setting the installation channel 110 as a U-shape or V-shape, a stable limit can be formed on the embedded section 210 and the supporting section 220 of the opening component 200, effectively preventing the opening component 200 from shifting, loosening, or falling off during long-term use. This ensures that the supporting section 220 can always maintain a stable and durable opening effect, effectively improving the structural stability of the opening component 200. Furthermore, regardless of whether the installation channel 110 is set as a U-shape or a V-shape, the lowest point of the installation channel 110 maintains a certain distance from the lower end face of the stop member 100, preventing the installation channel 110 from penetrating the entire stop member 100. This makes the installation of the opening component 200 more concealed and reduces its impact on the zipper's appearance.

[0047] like Figure 6As shown, in the sixth embodiment of this utility model, the blocking structure includes: a stop 100 disposed on the fabric tape 400. When the zipper is placed vertically, the stop 100 is specifically located at the upper and lower ends of the fabric tape 400. An installation channel 110 is provided inside the stop 100. The installation channel 110 is integrally formed in the stop 100. The installation channel 110 includes a bending portion 111 and a guide portion 112 disposed at one end of the bending portion 111. The bending portion 111 is used to embed the embedded section 210 of the supporting component 200, and the guide portion 112 is used to embed the partial supporting section 220 of the supporting component 200. By embedding the embedded section 210 and the partial supporting section 220 at one end of the embedded section 210 of the supporting component 200 in the installation channel 110, the supporting component 200 is stably limited, so that the supporting component 200 can maintain a certain shape for a long time, thereby playing a stable supporting role.

[0048] In some specific embodiments, the mounting channel 110 is generally J-shaped. In this case, the mounting channel 110 is a single-sided channel, and the embedded section 210 is a curved hook shape, serving as a support point for the channel of the supporting component 200, effectively ensuring the overall connection stability of the supporting component 200. Simultaneously, setting the supporting component 200 to a J-shape adapted to the mounting channel 110 facilitates integrated molding through processes such as wire bending, making it easier to process and reducing processing costs. Optionally, the guide portion 112 extends to the end face of the stop member 100 facing the chain tooth 500, allowing the portion of the supporting section 220 of the supporting component 200 extending out of the guide portion 112 to be inserted into the chain tooth 500. In this case, the chain tooth 500 is preferably a spiral chain tooth 500, and the portion of the supporting section 220 of the supporting component 200 extending out of the guide portion 112 is inserted into the hollow center of the chain tooth 500, and the portion of the supporting section 220 extending out of the guide portion 112 bends outward in its natural state. When the zipper is closed, the portion of the support section 220 extending out of the guide section 112 remains on the zipper teeth 500 in a state of bearing the squeezing force along the width direction of the zipper. When the zipper is opened, the portion of the support section 220 extending out of the guide section 112, under its own elasticity, drives one of the fabric tapes 400 away from the other fabric tape 400, so that the zipper opens to the preset size opening.

[0049] like Figure 7As shown, in the seventh embodiment of this utility model, in some specific embodiments, the guide portion 112 extends to one side of the stop member 100 along the width direction of the fabric tape 400. At this time, the portion of the supporting section 220 of the spreading member 200 extending out of the guide portion 112 is sewn to the fabric tape 400 or integrally formed on the fabric tape 400. The chain tooth 500 can be a spiral chain tooth 500 or a solid chain tooth 500. The portion of the supporting section 220 of the spreading member 200 extending out of the guide portion 112 is bent outward in its natural state or consistent with the extension direction of the guide portion 112. When the zipper is closed, the portion of the supporting section 220 extending out of the guide portion 112 is held on the fabric tape 400 in a state of bearing the squeezing force along the width direction of the zipper. When the zipper is opened, the portion of the supporting section 220 extending out of the guide portion 112, under its own elasticity, drives one of the fabric tapes 400 away from the other fabric tape 400, so that the zipper opens to a preset size opening.

[0050] like Figure 8 As shown, in the eighth embodiment of this utility model, the mounting channel 110 is generally arc-shaped, and the guide portion 112 extends to one side of the stop member 100 along the width direction of the fabric tape 400. At this time, the opening member 200 is generally V-shaped on one side and is embedded in the mounting channel 110. The bending portion 111 acts as a support point for the opening member 200, allowing the opening member 200 to open on one side, forming a separating force that opens to that side. At this time, the part of the opening member 200 extending from the guide portion 112 is sewn to the fabric tape 400 or integrally formed on the fabric tape 400. The part of the opening member 200 extending from the guide portion 112 bends outward in its natural state or is consistent with the extension direction of the guide portion 112, so as to ensure that when the zipper is opened, the part of the opening member 220 extending from the guide portion 112 drives one of the fabric tapes 400 away from the other fabric tape 400 under its own elasticity, so that the zipper opens to a preset size opening.

[0051] It should be noted that, depending on the actual needs, there are several ways to mold the stop 100. One method is to first position the expansion component 200, and then use an injection molding machine to injection mold it into the embedded section 210 of the expansion component 200, thus achieving the installation of the expansion component 200 on the stop 100. Another method is to use a metal stop 100, first creating a molding channel on the metal stop 100, placing the expansion component 200 within the installation channel 110, and then clamping the metal stop 100 onto the zipper tape 400.

[0052] It should be further noted that the installation channel 110 can be located on either the lower stop or the upper stop. When the installation channel 110 is located on the upper stop, the embedded section 210 of the spreading component 200 is embedded in the upper stop, and the two ends of the supporting section 220 away from the embedded section 210 are located on the lower stop, the fabric tape, or the chain teeth. The principle of setting the installation channel 110 on the lower stop is similar to that of setting the installation channel 110 on the upper stop; its purpose is to stably limit the position of the spreading component 200, so that the spreading component 200 maintains a certain shape for a long time, thereby achieving a stable spreading effect.

[0053] In some embodiments of this utility model, the blocking structure includes: a stop 100 disposed on the fabric belt 400. When the zipper is placed vertically, the stop 100 is specifically located at the upper and lower ends of the fabric belt 400. One or more installation channels are provided in the stop 100. The installation channels are used to embed part of the opening component to stably limit the opening component 200, so that the opening component 200 can maintain a certain shape for a long time, thereby playing a stable opening role.

[0054] like Figure 9 As shown, in the ninth embodiment of this utility model, an installation channel 110 is provided inside the stop member 100. The installation channel 110 is strip-shaped and extends to both sides of the stop member 100 along the width direction of the fabric tape 400. The portion of the spreading member 200 extending out of the installation channel 110 is sewn to the fabric tape 400 or integrally formed on the fabric tape 400. The portion of the spreading member 200 extending out of the guide portion 112 bends outward in its natural state or remains aligned with the extension direction of the installation channel 110. When the zipper is closed, the portion of the spreading member 200 extending out of the installation channel 110 remains on the fabric tape 400 to withstand the squeezing force along the width direction of the zipper. When the zipper is opened, the portion of the spreading member 200 extending out of the installation channel 110, under its own elasticity, drives one fabric tape 400 away from the other fabric tape 400, causing the zipper to open to a preset size opening.

[0055] like Figure 10As shown, in the tenth embodiment of this utility model, two mounting channels 110 are provided inside the stop member 100. Both mounting channels 110 are strip-shaped and combined to form a V-shape. The mounting channels 110 extend to both sides of the stop member 100 along the width direction of the fabric tape 400, and the two mounting channels 110 are not connected to each other. At this time, the portions of the two spreading members extending out of the mounting channels 110 are sewn to the fabric tape 400 or integrally formed on the fabric tape 400, and the portions of the spreading members 200 extending out of the guide portion 112 are bent outward in their natural state or are consistent with the extension direction of the mounting channels 110. When the zipper is closed, at least one of the spreading members 200 extends out of the mounting channel 110 and remains on the fabric tape 400 to withstand the squeezing force along the width direction of the zipper. When the zipper is opened, at least one of the spreading members 200 extends out of the mounting channel 110 and, under its own elasticity, drives one of the fabric tapes 400 away from the other fabric tape 400, so that the zipper opens to a preset size opening.

[0056] like Figure 11 As shown, in the eleventh embodiment of this utility model, an installation channel 110 is provided inside the stop member 100. The installation channel 110 is strip-shaped and extends to the end face of the stop member 100 facing the chain tooth 500. The portion of the expanding member 200 extending out of the installation channel 110 is sewn to the fabric tape 400, integrally formed into the fabric tape 400, or inserted into the chain tooth 500. The portion of the expanding member 200 extending out of the guide portion 112 bends outward in its natural state or remains aligned with the extending direction of the installation channel 110. When the zipper is closed, the portion of the expanding member 200 extending out of the installation channel 110 remains on the fabric tape 400 to withstand the squeezing force along the width direction of the zipper. When the zipper is opened, the portion of the expanding member 200 extending out of the installation channel 110, under its own elasticity, drives one of the fabric tapes 400 away from the other fabric tape 400, causing the zipper to open to a preset size opening.

[0057] like Figure 12As shown, in the twelfth embodiment of this utility model, two mounting channels 110 are provided inside the stop member 100. Both mounting channels 110 are strip-shaped and combined to form a V-shape. The two mounting channels 110 extend to the end face of the stop member 100 facing the chain tooth 500, and the two mounting channels 110 are not connected to each other. The portions of the two spreading members extending out of the mounting channels 110 are sewn to the fabric tape 400, integrally formed in the fabric tape 400, or inserted into the chain tooth 500. The portions of the spreading members 200 extending out of the guide portion 112 are bent outward in their natural state or are consistent with the extension direction of the mounting channels 110. When the zipper is closed, at least one portion of the two spreading members 200 extending out of the mounting channel 110 is held on the fabric tape 400 to withstand the squeezing force along the width direction of the zipper. When the zipper is opened, at least one portion of the two spreading members 200 extending out of the mounting channel 110, under its own elasticity, drives one of the fabric tapes 400 away from the other fabric tape 400, so that the zipper opens to a preset size opening.

[0058] like Figure 13 As shown, in addition to the above-mentioned blocking structure, this utility model also provides an automatic opening structure including the blocking structure disclosed in some of the above embodiments, further including: an opening component 200, the opening component 200 including: an embedded section 210 and a supporting section 220 disposed at both ends of the embedded section 210, the embedded section 210 being embedded in the bending portion 111, a portion of the supporting section 220 being embedded in the guide portion 112, and the other portion of the supporting section 220 extending out of the mounting channel 110 and disposed on the fabric tape 400 and / or the chain teeth 500; when the zipper is closed, at least one of the two supporting sections 220 extends out of the guide portion 112 and remains on the fabric tape 400 and / or the chain teeth 500 in a state of bearing the squeezing force along the width direction of the zipper; when the zipper is opened, at least one of the two supporting sections 220, under its own elasticity, drives one of the fabric tapes 400 away from the other fabric tape 400, so that the zipper opens to a preset size opening. By setting an installation channel 110 in the stop member 100, and embedding the embedded section 210 of the support member 200 and the partial support sections 220 at both ends of the embedded section 210 through the installation channel 110, the support member 200 is stably limited, so that the support member 200 can maintain a certain shape for a long time, thereby playing a stable supporting role.

[0059] like Figure 1 , Figure 15 and Figure 16As shown, the opening component 200 is shaped like a U, a V, or an O. The V-shaped opening component 200 is designed to fit a V-shaped mounting channel 110, and the U-shaped opening component 200 is designed to fit a U-shaped mounting channel 110. In this case, the opening component 200 provides efficient elastic opening force in a relatively simple form. The zipper does not need to overcome the force generated by the elastic deformation of the supporting section 220 during its reciprocating movement along the fabric tape 400, improving the smoothness of the zipper's reciprocating movement along the fabric tape 400 and ensuring the stability of the zipper when opening and closing. Similarly, the O-shaped opening component 200 is designed to fit an arc-shaped mounting channel 110. In this case, the opening component 200 can achieve a larger opening stroke. The shape of the opening component 200 can be selected according to actual needs, thus providing users with multiple options for different usage scenarios.

[0060] In some specific embodiments, the expansion component 200 is a strip-shaped elastomer, which includes elastic metal wire or shape memory metal wire. The expansion component 200 adopts a strip-shaped elastomer structure, preferably using elastic metal wire or shape memory metal wire. Both elastic metal wire and shape memory metal wire possess good elastic deformation capabilities, such as high-carbon steel or stainless steel wire, ensuring that the expansion component 200 has extremely high yield strength and fatigue resistance. This allows it to maintain a stable and strong expansion force during long-term opening and closing cycles of the zipper, resulting in better durability and reliability.

[0061] It should be noted that the length of the supporting section 220 of the stretching component 200 is at least 1 / 3 of the zipper length, so that the stretching section 220 provides a more uniform stretching effect on the zipper, avoids deformation due to insufficient support in some areas, and effectively improves the structural stability and shape retention of the zipper during use.

[0062] like Figure 14As shown, in addition to the above-mentioned blocking structure, this utility model also provides an automatic opening structure including the blocking structure disclosed in some of the above embodiments. The automatic opening structure further includes an opening component 200, which includes: an embedded section 210 and a supporting section 220 disposed at one end of the embedded section 210. The embedded section 210 is embedded in the bending portion 111, a portion of the supporting section 220 is embedded in the guide portion 112, and the other portion of the supporting section 220 extends out of the mounting channel 110 and is disposed on the fabric tape 400 and / or the chain teeth 500. When the zipper is closed, the supporting section 220 is held on the fabric tape 400 and / or the chain teeth 500 in a state of bearing the squeezing force along the width direction of the zipper. When the zipper is opened, the supporting section 220, under its own elasticity, drives one of the fabric tapes 400 away from the other fabric tape 400, so that the zipper opens to a preset size opening. By embedding the embedded section 210 of the expansion component 200 and the partial supporting section 220 at one end of the embedded section 210 in the installation channel 110, the expansion component 200 is stably limited, so that the expansion component 200 can maintain a certain shape for a long time, thereby playing a stable expansion role.

[0063] In addition to the aforementioned blocking structure, this utility model also provides an automatic opening structure including the blocking structure disclosed in some of the above embodiments. The automatic opening structure further includes an opening component 200. A portion of the opening component 200 is embedded in the mounting channel 110, and another portion extends out of the mounting channel 110 and is disposed on the fabric tape 400 and / or zipper teeth 500. When the zipper is closed, at least one portion of the opening component 200 extending out of the mounting channel 110 is held on the fabric tape 400 and / or zipper teeth 500 to withstand the squeezing force along the width direction of the zipper. When the zipper is opened, at least one portion of the mounting channel 110 extending out of the guide portion 112, under its own elasticity, drives one of the fabric tapes 400 away from the other fabric tape 400, causing the zipper to open to a preset size. By embedding a portion of the opening component 200 in the mounting channel 110 to stably limit the opening component 200, the opening component 200 can maintain a certain shape for a long time, thereby achieving a stable opening effect.

[0064] like Figure 17As shown, in addition to the aforementioned automatic opening structure, this utility model also provides a zipper including the stop structure disclosed in the above embodiments, further comprising: two parallel fabric strips 400, with chain teeth 500 provided on the edges of adjacent sides of the two fabric strips 400, and a zipper head 300 for engaging and disengaging the chain teeth 500 on both sides to achieve zipper opening and closing. The chain teeth 500 are one of the following: metal chain teeth, injection-molded block chain teeth, and spiral chain teeth. When the chain teeth 500 are metal chain teeth, the opening component 200 is connected to the fabric strips 400, and the metal chain teeth clamp the opening component 200 during zipper assembly. When the chain teeth 500 are injection-molded block chain teeth, the opening component 200 is connected to the fabric strips 400, and the injection-molded block chain teeth are directly formed onto the fabric strips 400 during zipper assembly. When the chain teeth 500 are spiral chain teeth, there is a portion of space within them to accommodate the engaging section 220 of the opening component 200, making zipper assembly more convenient. The structure of the other parts of the zipper is described in reference to existing technology and will not be repeated here.

[0065] In summary, by embedding the recessed section 210 of the expansion component 200 and the partial supporting sections 220 at both ends of the recessed section 210 in the installation channel 110, the expansion component 200 is stably limited, allowing it to maintain a certain shape for a long time, thus achieving a stable expansion effect. Moreover, compared to covering the stop component 100 with a cloth strip, this method provides better protection and concealment for the stop component 100, effectively improving the overall aesthetics of the zipper and eliminating the risk of lifting. The concealment effect of the expansion component 200 is also more stable.
