Description

Technical Field

[0001] The utility model relates to the technical field of zippers, in particular to a zipper slider and a zipper. Background Art

[0002] When existing zippers are used on clothing, the zipper is usually required to be firmly closed. However, in emergency situations, such as when the clothing needs to be opened to treat a wound or other situations where the zipper needs to be opened quickly, conventional zippers require the slider to be pulled onto the square latch at the lower end of the zipper, and then the latch is removed from the square and the slider to fully open the zipper. The operation is relatively complicated, time-consuming and labor-intensive, and inconvenient to open.

[0003] In the prior art, the upper wing plate or the lower wing plate of the slider is flexible, which realizes the rapid conversion from the closed state to the open state in the quick-open zipper. At the same time, by applying a lateral pulling force, the upper wing plate or the lower wing plate of the slider is bent, thereby expanding the width of the cloth tape insertion channel, so that it can bite into the cloth tape insertion channel. The deflection of the upper and lower wing plates is too large relative to the overall deflection range of the slider. When this deflection occurs a certain number of times, the upper and lower wing plates may have irreversible deformation, thereby changing the shape and size of the inner cavity of the slider, affecting the movement, engagement and separation of the teeth in the slider.

[0004] Therefore, how to prevent the lateral pulling force from causing irreversible deformation of the upper wing plate or the lower wing plate of the slider so that the zipper can be used normally is a technical problem that technicians in this field currently need to solve.

[0017] Preferably, the width of the second fabric seam is greater than the width of the first fabric seam.

[0018] A zipper includes any one of the sliders described above, and also includes a first zipper tape, a second zipper tape, and teeth installed on the first zipper tape and the second zipper tape, wherein a guide portion is provided at one end of the teeth close to the fragile portion in the second direction, and the thickness of the guide portion gradually decreases toward the fragile portion.

[0039] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0040] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0041] In the description of the present invention, it should be understood that the terms "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the position or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as a limitation of the present invention.

[0042] The purpose of the utility model is to provide a zipper slider and a zipper, which can prevent the lateral pulling force from causing irreversible deformation of the upper wing plate 110 or the lower wing plate 120 of the slider 100, so that the zipper can be used normally.

[0043] It should be noted that, in this embodiment, the X direction in the drawings is defined as the first direction, the Y direction is defined as the second direction, and the first direction and the second direction are set at an angle.

[0044] See also Figures 1 to 5 To achieve the above-mentioned purpose, the utility model provides a zipper slider 100, including an upper wing plate 110 and a lower wing plate 120 correspondingly arranged in a first direction, and a connecting column 130 connected to the upper wing plate 110 and the lower wing plate 120 to form an inner cavity 140, the connecting column 130 is located at the front end of the inner cavity 140 to guide the teeth 200 to move along the front end of the inner cavity 140 to the rear end of the inner cavity 140 and then engage, and the side edge portions of one side of the upper wing plate 110 and the lower wing plate 120 in the second direction are provided with flanges 111 extending toward each other, and a first cloth seam 160 for the first zipper tape 310 to pass through is formed on the end edge side of the flange 111.

[0045] On the other side of the upper wing plate 110 and the lower wing plate 120 in the second direction, at least one of the side edges of the upper wing plate 110 and the lower wing plate 120 is provided with a flange 111 extending toward each other, and a second fabric seam 150 for passing the second zipper tape 320 is formed on the end edge side of the flange 111.

[0046] Specifically, there may be one flange 111 forming the second fabric seam 150, and it is disposed on the side facing the upper wing plate 110 or the lower wing plate 120; there may be two flanges 111 forming the second fabric seam 150, which are respectively located on the side facing the upper wing plate 110 and the lower wing plate 120, and at least one of the two flanges 111 may be smaller in width in the first direction than the flange 111 forming the first fabric seam 160, so that the width of the second fabric seam 150 can be greater than the width of the first fabric seam 160.

[0047] It should be noted that a pair of flanges 111 arranged in the upper and lower wing plates 110 and 120 form a first fabric seam 160 for the first zipper tape 310 to pass through, and the other side of the upper and lower wing plates 110 and 120 forms a second fabric seam 150 for the second zipper tape 320 to pass through through the flanges 111. The flanges 111 are used to limit the teeth 200, prevent the teeth 200 from escaping from the inner cavity 140 along the first fabric seam 160 or the second fabric seam 150, and ensure that the teeth 200 can effectively mesh with each other.

[0048] At least one flange 111 forming the second fabric seam 150 is provided with a fragile portion 112 with deformation capability, and the first direction and the second direction are arranged at an angle, preferably, the first direction and the second direction are perpendicular to each other.

[0049] By providing at least one fragile portion 112 with deformation ability in the flange 111 where the second cloth seam 150 is formed between the upper wing plate 110 and the lower wing plate 120, when the slider 100 or the tooth 200 is subjected to a pulling force in the second direction, only the fragile portion 112 is deformed outwardly to allow the tooth 200 to separate from the inner cavity 140 along the second direction, thereby reducing the flexure range of the slider 100 and reducing the influence of the position where the slider 100 is deformed on the normal use of the zipper, thereby preventing the lateral pulling force from causing irreversible deformation of the upper wing plate 110 or the lower wing plate 120 of the slider 100, so that the zipper can be used normally.

[0050] In this embodiment, the fragile portion 112 is configured such that when the fragile portion 112 is subjected to tension in the second direction, the fragile portion 112 deforms toward the side away from the inner cavity 140 so that the width of the second fabric seam 150 in the first direction is greater than the thickness of the tooth 200 in the first direction.

[0051] The flange 111 forming the second fabric seam 150 is provided with a fragile portion 112 that will deform when subjected to a certain transverse tension. Therefore, when the zipper is closed and subjected to a certain transverse tension, the teeth 200 in the inner cavity 140 will abut against the flange 111 and exert a force toward the outside of the inner cavity 140 on the flange 111, and the flange 111 with the fragile portion 112 will deform outwards (such as Figure 4 The dotted line is a schematic diagram of the position of the flange 111 after deformation), thereby expanding the width of the second fabric seam 150 in the first direction until the width of the second fabric seam 150 in the first direction is greater than the thickness of the tooth 200 in the first direction, and the tooth 200 can be separated from the inner cavity 140 of the slider 100 from the fabric seam, and the deformed part of the slider 100 is only set in the flange 111, so that fewer structural parts are required and the affected position is smaller, and the impact of subsequent deformation on the normal use of the slider 100 and the zipper function can also be smaller.

[0052] It can be understood that the thickness of the end of the flange 111 with the fragile portion 112 away from the cloth seam in the second direction is greater than the thickness of the end close to the cloth seam in the second direction. Part of the flange 111 becomes thinner to form a fragile portion 112 that is easy to deform. When the flange 111 is subjected to force, the fragile portion 112 deforms first and then drives the flange 111 with the fragile portion 112 to deform and expand as a whole. The structure is simple and easy to form. The fragile portion 112 can also be formed at any position of the flange 111 in the first direction. It is only necessary to allow the flange 111 to have a position that is easy to deform to drive the flange 111 to deform as a whole.

[0053] The upper wing plate 110 and the lower wing plate 120 are configured such that when the fragile portion 112 is subjected to a tensile force in the second direction, the upper wing plate 110 and the lower wing plate 120 are not deformed or are substantially not deformed.

[0054] Although when the fragile portion 112 is subjected to the pulling force in the second direction, the fragile portion 112 is deformed toward the side away from the inner cavity 140, so that the chain tooth row on this side can be squeezed out of the second cloth seam 150, the upper wing plate 110 and the lower wing plate 120 are not deformed or are basically not deformed. The extrusion of the chain tooth row is mainly caused by the deformation of the fragile portion 112, rather than the deformation of the upper wing plate 110 and the lower wing plate 120. The upper wing plate 110 and the lower wing plate 120 usually do not deform, but at the same time, the upper wing plate 110 and the lower wing plate 120 are not deformed. 0 and the lower wing plate 120 may be subjected to partial squeezing force, but the squeezing force will not cause significant changes in the appearance of the upper wing plate 110 and the lower wing plate 120, which is essentially different from the flange 111 driving the upper wing plate 110 and the lower wing plate 120 to deform so as to change the width of the first cloth seam 160 and / or the second cloth seam 150. Therefore, when the fragile portion 112 is subjected to a pulling force in the second direction, the fragile portion 112 is deformed toward the side away from the inner cavity 140 to satisfy the disengagement of the chain tooth row.

[0055] The flange 111 includes an abutment surface located in the inner cavity 140, and the abutment surface is an inclined surface, an arc surface, or a vertical surface, etc. Figure 4 As shown, the fragile portion 112 of this embodiment is arranged at one end of the flange 111 close to the second fabric seam 150, and the thickness of the fragile portion 112 gradually decreases toward the second fabric seam 150. This structure is only processed at the end of the flange 111, and the processing operation during the production process can be more convenient.

[0056] Among them, the fragile portion 112 occupies all or part of the corresponding flange 111, and the fragile portion 112 can be a structure with two side surfaces in the second direction inclined toward the middle and gradually decreasing thickness, so that the fragile portion 112 is more evenly stressed; the side of the fragile portion 112 away from the inner cavity 140 can also adopt a vertical plane, and the side of the fragile portion 112 located on the inner cavity 140 is a structure with a thickness gradually decreasing that gradually inclines toward the above-mentioned vertical plane, so that the flange 111 is smoother, and when the appearance of the slider 100 is observed from the outside, the fragile portion 112 will not affect the appearance of the slider 100.

[0057] In this embodiment, the thickness of the fragile portion 112 in the first direction is 0.1-0.5 times the thickness of the corresponding flange 111 in the first direction. Within this range, the deformation of the fragile portion 112 is relatively easy to drive the flange 111 to expand outward as a whole, and the flange 111 as a whole will not be too fragile to be damaged; the width of the second fabric seam 150 in the first direction is 0.2-0.9 times the width of the tooth 200 in the first direction. Within this range, the fragile portion 112 and the flange 111 will not affect the normal opening and closing of the zipper, and the tooth 200 is not easy to fall out of the second fabric seam 150. When the zipper is subjected to a large lateral tension, the tooth 200 can also effectively fall out of the second fabric seam 150.

[0058] Among them, the fragile part 112 can be set separately from the slider 100 and connected together through post-assembly methods such as clamping and riveting, which makes production, assembly and use more flexible. The fragile part 112 can also be integrally formed with the slider 100 through mold casting, injection molding, die casting and other methods, which makes molding faster.

[0059] See also Figures 8 to 10 In this embodiment, a portion of the flange 111 is provided with a plurality of through holes 114 penetrating the flange 111. The through holes 114 are provided to reduce the strength of the portion of the flange 111, making it easier to deform. The portion where the through holes 114 are provided is the fragile portion 112. The fragile portion 112 can also form a special hole pattern, such as a honeycomb hole 115 structure or an elongated hole 116 structure, to achieve visual and strength changes. Compared with the thickness change of the fragile portion 112, the through holes 114 can achieve a deformation effect while the weight of the slider 100 can also be lighter, thereby achieving lightweighting of the slider 100.

[0060] See also Figure 10 to Figure 11In this embodiment, a plurality of grooves are provided at some positions of the flange 111. The grooves are provided to reduce the strength of some positions of the flange 111, making it easier to deform. The position where the grooves are provided is the fragile portion 112. The grooves can be provided on both the inner and outer sides of the flange 111. The fragile portion 112 can also form a special groove shape, such as a honeycomb groove structure or an elongated groove 117 structure, to achieve visual and strength changes. Compared with the through hole 114 design, the groove design can achieve a certain strength of the flange 111 while achieving a deformation effect.

[0061] See also Fig.12 , at least part of the flange 111 can be made of a material that is easier to deform, such as an elastic material, a flexible material, etc. The elastic member 118 made of a material that is easier to deform in the flange 111 is the fragile portion 112. The fragile portion 112 can be formed on the slider 100 that is not easily deformed by direct injection molding, or it can be formed first and then assembled on the slider 100 by means of clamping, riveting, etc. Compared with the other embodiments mentioned above, the fragile portion 112 is made of other materials to allow the manufacturer to have more freedom in choice, such as choosing different color materials to produce different visual effects, and choosing some more wear-resistant or softer deformable materials, which can reduce the damage of the flange 111 to the teeth 200 during normal use of the zipper.

[0062] See also Figure 1 A zipper includes the above-mentioned slider 100, and also includes a first zipper tape 310, a second zipper tape 320, and a tooth 200 installed on the first zipper tape 310 and the second zipper tape 320, and the tooth 200 is provided with a guide portion 210 at one end close to the fragile portion 112 in the second direction, and the thickness of the guide portion 210 gradually decreases in the direction close to the fragile portion 112.

[0063] The guide portion 210 includes a first end that is smaller and a second end that is larger in the second direction, and the first end is close to the fragile portion 112 .

[0064] The zipper includes a first zipper tape 310 and a second zipper tape 320 arranged on the left and right, teeth 200 arranged correspondingly on the first zipper tape 310 and the second zipper tape 320, a slider 100 used to close the zipper, and stoppers 330 arranged at both ends of the tape to prevent the slider 100 from falling out.

[0065] See also Figure 6 and Figure 7The tooth 200 is provided with a guide portion 210 whose thickness gradually decreases from the tooth body to the tooth foot at least on one side close to the fragile portion 112. By the gradual thickness design of the guide portion 210, when the tooth 200 and the flange 111 are pressed together, the guide portion 210 can more effectively guide the flange 111 provided with the fragile portion 112 to expand outward, so that the tooth 200 can be separated from the inner cavity 140 of the slider 100. In this embodiment, the guide portion 210 and the fragile portion 112 can be provided with a mutually matching The guiding structure, for example, the guiding portion 210 is provided with a first convex curved slope 211, and the fragile portion 112 is provided with a second concave curved slope 113, and the first curved slope 211 and the second curved slope 113 are located on the side facing the guiding portion 210 and the fragile portion 112, so that the abutment cooperation between the first curved slope 211 and the second curved slope 113 can more effectively guide the tooth 200 to disengage from the inner cavity 140, so that the tooth 200 can quickly detach from the slider 100.

[0066] The first arcuate slope 211 can be arranged on both sides of the guide portion 210 in the first direction, or on one side of the guide portion 210 in the first direction, and the fragile portion 112 is correspondingly arranged so that the first arcuate slope 211 and the second arcuate slope 113 can cooperate with each other. When only one fragile portion 112 is arranged on the two flanges 111 corresponding to the guide portion 210, in order to maintain the normal movement, engagement and separation of the teeth 200 in the inner cavity 140, the deformation of the slider 100 is limited to one side, thereby reducing the deformation range of the slider 100.

[0067] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0068] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0069] This article uses specific examples to illustrate the principles and implementation methods of the utility model. The above examples are only used to help understand the method and core ideas of the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the utility model.
