Description

Technical Field

[0001] This invention relates to the field of zippers, and more specifically to a zipper pull and a zipper for use in concealed zippers. Background Technology

[0002] Zippers are common products in daily life, mainly used in clothing, bags, tents, car seat covers, and other industries. There are many types of zippers, including the concealed zipper. When used on car seat covers, the concealed zipper teeth create a seamless and aesthetically pleasing look. The concealed zipper pull, mounted on the fabric strip, plays a crucial role in the operation of the concealed zipper, allowing the zipper to be opened or closed by pulling it.

[0003] Currently, the zipper pulls on car seat covers typically lack pull tabs and self-locking functions. This is because adding self-locking and pull tabs would cause the top of the zipper pull to protrude significantly, potentially scratching the skin and being unsightly. Generally, a pull ring is placed at the front of the zipper pull, and a special hook is used to engage the ring to pull the zipper pull and close the zipper. Once closed, the pull ring is hidden within the zipper tape. Because the zipper pulls usually lack self-locking and a small portion of the zipper tape protrudes from the top, wiping the car seat covers can cause the zipper pull to move when this exposed portion is touched, thus opening the zipper. Since car owners typically lack the special hook, they cannot close the zipper themselves and must take it to a repair shop, which is extremely inconvenient. Summary of the Invention

[0004] The purpose of this invention is to overcome the above-mentioned technical problems and provide a zipper pull and zipper for invisible zippers.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a zipper head for an invisible zipper, comprising a zipper head body and a zipper head upper plate. The front end of the zipper head body is provided with a pull ring. The zipper head body is provided with a chain groove. A connecting post is provided in the chain groove. The zipper head upper plate is provided with a connecting seat. The connecting seat is provided with a connecting groove. The connecting post is installed in the connecting groove. A first limiting device is provided between the connecting post and the zipper head upper plate or between the connecting seat and the bottom of the chain groove. The blocking device includes a clearance space. The clearance space is used to allow the zipper head upper plate to move towards the tail end of the zipper head body. The top of the chain groove is provided with an inner flange. The sidewall of the inner flange and the sidewall of the zipper head upper plate form a tape passage. The sidewall of the connecting seat and the sidewall of the chain groove form a tooth passage. When the zipper head upper plate moves towards the tail end of the zipper head body, the width of the tape passage and the tooth passage both decrease to clamp the zipper tape and the tooth respectively.

[0006] Furthermore, the first limiting device includes a first limiting protrusion and a first limiting groove. The first limiting protrusion is disposed on both sides of the connecting post, and the first limiting groove is disposed on both side walls of the connecting groove. After the connecting post is installed in the connecting groove, the first limiting protrusion is installed in the first limiting groove.

[0007] Furthermore, the blocking device also includes a locking block and a locking groove. The locking block is disposed on the top of the connecting column, and the locking groove is disposed on the upper plate of the pull head. After the connecting column is installed in the connecting groove, the locking block is locked into the locking groove.

[0008] Furthermore, the locking block is provided with an auxiliary inclined surface.

[0009] Furthermore, the blocking device also includes a blocking nose, one end of which is fixedly mounted on the upper plate of the pull head, and the other end of which bends downward and extends to the front of the connecting post.

The blocking groove is located at the front end of the connecting column.

[0011] Furthermore, it also includes a second limiting device, which is disposed between the tail end of the connecting column and the side wall of the connecting groove.

[0012] Furthermore, the second limiting device includes a second limiting protrusion and a second limiting groove. The second limiting protrusion is disposed at the tail end of the connecting column, and the second limiting groove is disposed on the side wall of the connecting groove, wherein the second limiting protrusion is inserted into the second limiting groove.

[0013] The present invention also provides a zipper, including a zipper tape and zipper teeth, the zipper teeth being disposed on the zipper tape, and further including the aforementioned slider for an invisible zipper, the zipper teeth being disposed on the zipper tooth passage, and the zipper tape being disposed on the tape passage.

[0014] As can be seen from the above description of the present invention, compared with the prior art, the zipper head and zipper for concealed zippers provided by the present invention have the following advantages: The zipper head for concealed zippers includes a zipper head body and a zipper head upper plate. The zipper head body is provided with a chain groove, and a connecting post is provided in the chain groove. The zipper head upper plate is provided with a connecting seat, and the connecting seat is provided with a connecting groove. The connecting post is installed in the connecting groove, thereby connecting the zipper head upper plate and the zipper head body together. A first limiting device is provided between the connecting post and the connecting groove. A blocking device is provided between the connecting post and the zipper head upper plate or between the connecting seat and the bottom of the chain groove. The connecting seat is installed in the connecting groove by the cooperation of the first limiting device and the blocking device. On the connecting post, to prevent the connecting post from disengaging from the connecting groove, specifically, the blocking device includes a clearance space. The clearance space is used to allow the top plate of the zipper head to move a certain distance towards the tail end of the zipper head body. The top of the chain groove is provided with an inner flange. The side wall of the inner flange and the side wall of the top plate of the zipper head form a tape passage. The side wall of the connecting seat and the side wall of the chain groove form a tooth passage. When the top plate of the zipper head moves towards the tail end of the zipper head body, the width of the tape passage and the tooth passage both decrease to clamp the zipper tape and the tooth respectively, thereby preventing the zipper head used for the concealed zipper from continuing to open the zipper, playing a self-locking role and preventing the zipper from being pulled open.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0025] The present invention provides a zipper pull and zipper for invisible zippers, which can be used on items that are not frequently opened, such as car seat covers, mattress covers, and stuffed animals.

[0026] Reference Figures 1-9 As shown, the present invention provides a zipper pull for an invisible zipper, comprising a zipper pull body 1 and a zipper pull top plate 2. The front end of the zipper pull body 1 is provided with a pull ring 11, which is used to hook the zipper pull when the zipper is closed. The zipper pull body 1 is provided with a chain groove 12, and a connecting post 121 is provided in the chain groove 12. The zipper pull top plate 2 is provided with a connecting seat 21, and a connecting groove 211 is provided on the connecting seat 21. The connecting post 121 is installed in the connecting groove 211, thereby connecting the zipper pull top plate 2 and the zipper pull body 1 together. A first limiting device 3 is provided between the connecting post 121 and the connecting groove 211. A blocking device 4 is provided between the connecting post 121 and the zipper pull top plate 2 or between the connecting seat 21 and the bottom of the chain groove 12. The connecting seat 21 is installed on the connecting post 121 by the cooperation of the first limiting device 3 and the blocking device 4, preventing the connecting post 121 from detaching from the connecting groove 211.

[0027] Specifically, the blocking device 4 includes a clearance space 41, which allows the top plate 2 of the zipper pull to move towards the tail end of the zipper pull body 1. The top of the chain groove 12 has an inner flange 122, and the sidewall of the inner flange 122 and the sidewall of the top plate 2 of the zipper pull form a fabric tape passage 5 for the zipper tape to pass through. The sidewall of the connecting seat 21 and the sidewall of the chain groove 12 form a chain tooth passage 6 for the chain teeth to pass through. When the top plate 2 of the zipper pull moves towards the tail end of the zipper pull body 1, the widths of the fabric tape passage 5 and the chain tooth passage 6 both decrease to clamp the zipper tape and chain teeth respectively, thus preventing the zipper pull for the concealed zipper from opening the zipper, achieving a self-locking effect and preventing the zipper from being pulled open.

[0028] The first limiting device 3 includes a first limiting protrusion 31 and a first limiting groove 32. The first limiting protrusion 31 is disposed on both sides of the connecting post 121, and the first limiting groove 32 is disposed on both side walls of the connecting groove 211. After the connecting post 121 is installed in the connecting groove 211, the first limiting protrusion 31 is installed in the first limiting groove 32, thereby preventing the connecting post 121 from detaching from the connecting groove 211 in the vertical direction, and restricting the connecting seat 21 to move only towards the tail end of the pull head body 1, and not towards the front end of the pull head body 1.

[0029] A second limiting device 7 is provided between the tail end of the connecting post 121 and the side wall of the connecting groove 211. The second limiting device 7 is used to further prevent the connecting post 121 from detaching from the connecting groove 211 in the vertical direction, and to restrict the connecting seat 21 to move only towards the tail end of the slider body 1, and not towards the front end of the slider body 1. The second limiting device 7 includes a second limiting protrusion 71 and a second limiting groove 72. The second limiting protrusion 71 is disposed at the tail end of the connecting post 121, and the second limiting groove 72 is disposed on the side wall of the connecting groove 211, wherein the second limiting protrusion 71 is inserted into the second limiting groove 72.

[0030] In one embodiment, refer to Figures 1-5 As shown, the blocking device 4 also includes a locking block 42 and a locking groove 43. The locking block 42 is disposed on the top of the connecting post 121, and the locking groove 43 is disposed on the upper plate 2 of the zipper pull. After the connecting post 121 is installed in the connecting groove 211, the locking block 42 is engaged in the locking groove 43. Specifically, the locking block 42 is provided with an auxiliary inclined surface 421, which is used to assist the locking block 42 in entering the locking groove 43. The clearance space 41 is the space between the front end of the locking block 42 and the front side wall of the locking groove 43, that is, the length of the locking block 42 is less than the length of the locking groove 43. So when the upper plate 2 of the zipper pull is subjected to force, it can move towards the tail end of the zipper pull body 1. At this time, the width of the fabric tape passage 5 and the chain tooth passage 6 gradually decreases until the zipper tape and chain teeth are clamped, so that the zipper pull cannot open the zipper, thus playing a self-locking role.

[0031] In another embodiment, refer to Figure 6 , Figure 7As shown, the blocking device 4 also includes a blocking nose 44, one end of which is fixedly mounted on the upper plate 2 of the pull head, and the other end of which bends downward and extends to the front of the connecting post 121. The clearance space 41 is the space between the end of the blocking nose 44 and the front sidewall of the connecting post 121.

[0032] In another embodiment, refer to Figure 8 , Figure 9 As shown, the blocking device 4 further includes a blocking block 45 and a blocking groove 46. The blocking block 45 is disposed on the bottom of the connecting seat 21, and the blocking groove 46 is disposed on the bottom of the chain groove 12. The blocking groove 46 is located at the front end of the connecting post 121. The clearance space 41 is the space between the side wall of the blocking block 45 and the rear side wall of the blocking groove 46.

[0033] The present invention also provides a zipper, including a zipper tape and zipper teeth, the zipper teeth being disposed on the zipper tape, and further including the aforementioned zipper pull for an invisible zipper, the zipper teeth being disposed on the zipper tooth passage 6, and the zipper tape being disposed on the tape passage 5.

[0034] The above are merely some specific embodiments of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantial modifications made to the present invention using this concept shall be considered as infringing upon the protection scope of the present invention.
