Detailed Implementation
[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0032] The core of this invention is to provide a closed-end zipper that can solve the problem of zipper breakage through self-adjustment.
[0033] Another core aspect of this invention is to provide an outdoor product that includes the aforementioned zipper.
[0034] Please refer to the attached document. Figure 1 To be continued Figure 6 The closed zipper provided in this application includes: a first toothed strip 1, a second toothed strip 2, wherein the teeth of the second toothed strip 2 are separable from or interlock with the teeth of the first toothed strip 1; a lower stop shell 4 provided with a groove at the first end of the first toothed strip 1 and the second toothed strip 2; and a sliding device 3 movably disposed in the groove and sleeved at the first end of the first toothed strip 1 and the second toothed strip 2.
[0035] Specifically, the first ends of the first toothed rack 1 and the second toothed rack 2 interlock with each other, and the sliding device 3 is sleeved on the first ends of the first toothed rack 1 and the second toothed rack 2. A part of the sliding device 3 is set inside the groove of the lower stop housing 4. When the first toothed rack 1 and the second toothed rack 2 experience a chain breakage, the sliding device 3 drives the first toothed rack 1 and the second toothed rack 2 to bring the broken chain into the lower stop housing 4. The compression in the groove of the lower stop housing 4 causes the broken chain to re-interlock. After the chain breakage problem is solved, pulling the first toothed rack 1 and the second toothed rack 2 to reset them will restore normal use.
[0036] Based on the above embodiment, a zipper head 5 is fitted on the first toothed strip 1 and the second toothed strip 2. The first toothed strip 1 and the second toothed strip 2 engage with each other through the zipper head 5 to realize the opening and closing of the zipper.
[0037] Specifically, the first toothed strip 1 and the second toothed strip 2 are separated or engaged by pulling the zipper head 5. The range of motion of the zipper head 5 is between the second end of the zipper and the lower stop shell 4.
[0038] In some embodiments, the lower stop housing 4 is provided with an elastic member 6, one end of which is connected to the sliding device 3, and the other end of which is fixed to the bottom of the groove inside the lower stop housing 4.
[0039] Specifically, an elastic element 6 is provided in the groove of the lower stop housing 4. One end of the elastic element 6 is fixed to the bottom of the groove, and the other end of the elastic element 6 is fixed to the bottom of the sliding device 3 located in the groove. The sliding device 3 drives the first toothed rack 1 and the second toothed rack 2 to move into the groove of the lower stop housing 4, applying pressure to the elastic element 6. This causes the exposed chain of the first toothed rack 1 and the second toothed rack 2 to be squeezed by the lower stop housing 4, thereby causing the exposed chain to re-engage and resume normal use. Then, the sliding device 3 is released, and the elastic element 6 pushes the sliding device 3 out of the groove, causing the sliding device 3 to return to its original position. There is no need to manually pull the sliding device 3 to reset, making it more convenient to use.
[0040] Optionally, the elastic element 6 can be a spring.
[0041] In some embodiments, sliding guide rails 7 are provided on both sides of the groove of the lower stop housing 4, and sliding protrusions 8 are provided on both sides of the sliding device 3. The sliding protrusions 8 are embedded in the sliding guide rails 7 so that the sliding device 3 can reciprocate along the sliding guide rails 7.
[0042] Specifically, a straight sliding guide rail 7 is provided on both sides of the groove inside the lower stop housing 4, and sliding protrusions 8 are provided on both sides of the sliding device 3. The sliding protrusions 8 are embedded in the sliding guide rail 7. When using the sliding device 3 to solve the chain breakage problem, the sliding device 3 is pushed to move along the sliding guide rail 7 to the bottom of the groove of the lower stop housing 4, so that the first toothed rack 1 and the second toothed rack 2 can move in a straight line. The straight movement of the first toothed rack 1 and the second toothed rack 2 can ensure that the first toothed rack 1 and the second toothed rack 2 are aligned, so that when the chain breakage part of the first toothed rack 1 and the second toothed rack 2 enters the groove of the lower stop housing 4, it can be accurately positioned, avoiding the failure of repair or secondary wear of the toothed racks due to misalignment of the teeth of the first toothed rack 1 and the second toothed rack 2.
[0043] Based on the above embodiment, the sliding guide rail 7 is provided with a detachable locking block near the port of the lower stop housing 4 to limit the sliding device 3.
[0044] Specifically, the sliding guide rail 7 extends from the port of the groove in the lower stop housing 4 to the bottom of the groove. Therefore, a detachable locking block is provided at the port of the sliding guide rail 7 to prevent the sliding guide rail 7 from derailing due to excessive force during use. The locking block can be glued or melted by heating. During the assembly process, the sliding device 3 is first fitted onto the first toothed rack 1 and the second toothed rack 2. Then, the sliding protrusion 8 of the sliding device 3 is embedded into the sliding guide rail 7. Finally, the locking block is fixed to the end of the sliding guide rail 7. When the sliding device 3 is damaged, especially when the sliding protrusion 8 is broken, the locking block can be disassembled for easy maintenance.
[0045] In some embodiments, a sheet 9 is provided at the port of the recess of the lower stop housing 4, and the sheet 9 is a plastic part.
[0046] Specifically, a plastic sheet 9 can be placed in the groove of the lower stop shell 4. The sheet 9 serves as a guide. In addition, since the closed zipper is generally fixed to the fabric, the plastic sheet 9 can harden the fabric, making it easier for the zipper to close.
[0047] Optionally, sheet 9 can be an alloy part with a certain hardness.
[0048] In some embodiments, the sheet 9 is provided with a through hole for fixing the sheet 9 to outdoor products.
[0049] Specifically, perforations are made in the sheet 9 so that the sheet 9 can be fixed to outdoor products by sewing or riveting, preventing the sheet 9 from falling off.
[0050] In some embodiments, the sliding device 3 is a U-shaped housing, and a snap-fit device is provided at the port of the sliding device 3. The sliding device 3 is snapped into the first end of the first toothed rack 1 and the second toothed rack 2 in the biting state by the snap-fit device.
[0051] Specifically, a snap-fit device is provided at the port of the sliding device 3 of the U-shaped shell, which enables the sliding device 3 to snap into the first end when the first toothed bar 1 and the second toothed bar 2 are engaged. The snap-fit device is detachable. When the sliding device 3 is worn due to prolonged use, it can be disassembled and replaced without replacing the entire zipper, thus saving costs.
[0052] Based on the above embodiment, the first toothed rack 1 is connected to the first fabric surface 10, the second toothed rack 2 is connected to the second fabric surface 11, and the first fabric surface 10 and the second fabric surface 11 are fixedly connected by the lower stop shell 4.
[0053] Specifically, the first toothed strip 1 and the second toothed strip 2 are connected to two pieces of fabric respectively, and the two pieces of fabric are fixed by the lower stop shell 4, so that the zipper can open and close the box or backpack by pulling the zipper head 5.
[0054] In addition to the closed zipper mentioned above, the present invention also provides an outdoor product that includes the closed zipper disclosed in the above embodiments. For the structure of other parts of the outdoor product, please refer to the prior art, which will not be repeated here.
