Description

Technical Field

[0001] The present invention relates to the manufacturing technology of travel bags, and more particularly to fasteners for travel bags.

Background Art

[0002] A fastener is a fastening member that joins or separates objects by engaging teeth arranged like teeth, and has high convenience in opening and closing, as well as high safety, reliability, and durability. In addition, since the fastener can join or separate objects according to the usage situation and maintain the fastening effect in a stable state at the same time, it is widely used in clothing, bags, tents, etc.

[0003] Specifically, fasteners are applied to various fields such as people's daily lives, aerospace, military equipment, and medical equipment. In the fashion-related industry, fasteners are often used not only for openings such as trousers, skirts, and jackets, but also for opening and closing parts of various types of bags. In the outdoor supplies-related industry, fasteners are used for fastening tent members.

[0004] In conventional fasteners for travel bags, since the cloth part of the fastener has no elasticity, when the slider passes through the bent or non-linear part of the travel bag, the cloth part of the fastener is excessively pulled, which hinders the sliding of the slider and often causes the engaging teeth to deviate. Therefore, there is room for improvement.

[0005] In other words, when the slider passes through the bent or non-linear part of the travel bag, the inelastic cloth part of the fastener is excessively pulled, which hinders the sliding of the slider and easily causes the deviation of the engaging teeth. This is the problem of conventional fasteners for travel bags, that is, the problem to be solved by the present invention.

Summary of the Invention

Problems to be Solved by the Invention

[0006] In view of the above-mentioned drawbacks, the main object of the present invention is to provide a fastener for travel bags that can generate relatively good elasticity, slide smoothly, and is less likely to cause the deviation of the service teeth.

Means for Solving the Problems

[0007] To solve the above-mentioned problems, the fastener for travel bags includes a first shell, a second shell, and an elastic fastener. The first shell and the second shell are combined. The elastic fastener has two or more opposing tape bodies and service teeth. Each tape body is separately connected to the first shell and the second shell, and has one or more horizontal weft units and a plurality of vertical warp threads. The weft unit has elastic weft threads. The elastic weft threads are bent along the length direction of the warp threads and are alternately woven with the tip and end portions of the warp threads. The service teeth are arranged on the elastic weft threads.

[0008] Specifically, since the weft unit is made of an elastic material, it not only brings good elasticity to the entire fastener, but also effectively responds to the opening, closing, and compression of the travel bag, that is, the flexibility during use can be improved. Since the elastic weft threads and the warp threads are alternately woven, the wear resistance and sealing performance of the fastener can be improved, the fastener can be prevented from being damaged due to frequent use, and the sealing performance of the shell can be ensured. That is, with the above-mentioned design, not only can the fastener be pulled more smoothly to open and close, but also the opening and closing operation can be maintained in a stable state for travel bags with relatively heavy loads or irregular shapes.

[0009] In a relatively preferred case, the weft unit of the elastic fastener further has one or more inelastic wefts. The inelastic weft is disposed between the elastic weft and the teeth, bends along the length direction of the warp, and is alternately woven with the tip and end of the warp, and at the same time alternately connects the bent portions of the elastic weft and the teeth. That is, the bent portions of the inelastic weft alternately connect the U-turn portions and the teeth of the elastic weft to form a tight structure. The elastic weft generates the required elasticity, enabling the fastener to accommodate objects of various sizes. The inelastic weft increases the rigidity of the fastener, ensures elasticity, suppresses excessive bending and unstable situations, and can improve the convenience during use. The design of alternately connecting the inelastic weft and the teeth more tightly binds the space between the teeth and the weft, improves the durability of the fastener and the smoothness during opening and closing, and can prevent the deviation or damage of the teeth during use.

[0010] In a relatively preferred case, the teeth of the elastic fastener and the inelastic weft are interconnected by a sewing machine. Connecting the teeth and the inelastic weft with a sewing machine can effectively increase the stability of the teeth and reduce the risk of the teeth deviating during sliding. That is, the connection method by the sewing machine effectively improves the tensile strength of the entire structure, can withstand a greater tension, and can maintain stability under high-pressure or high-load situations.

[0011] In a relatively preferred case, the inelastic weft of the elastic fastener passes alternately through a plurality of warps to form a left non-elastic U-turn portion on the left side and a right non-elastic U-turn portion on the right side. The left non-elastic U-turn portion and the right non-elastic U-turn portion are alternately woven. The teeth are sewn into the right non-elastic U-turn portion by a sewing machine. Summarizing the above content, the U-turn structure of the inelastic weft can strengthen the tensile strength of the fastener, and sewing the teeth into the right non-elastic U-turn portion by a sewing machine can improve the stability and durability of the teeth.

[0012] In a relatively preferred case, the elastic fastener has a non-elastic side protection member between the elastic weft yarn and the engaging teeth. One side of the non-elastic side protection member is connected to the engaging teeth, and the other side is connected to the elastic weft yarn. Specifically, by connecting one side to the engaging teeth and the other side to the elastic weft yarn, the side protection member forms a good bridge. The non-elastic side protection member can effectively stabilize the connection state between the elastic weft yarn and the engaging teeth, thereby suppressing the situation where the fastener deforms or loosens during use. The non-elastic side protection member strongly supports between the elastic weft yarn and the engaging teeth to tightly connect and stabilize the elastic weft yarn and the engaging teeth.

[0013] In a relatively preferred case, the elastic weft yarn of the elastic fastener has a spandex yarn and a double-twisted polyester yarn wound around the outer peripheral wall of the spandex yarn. The double-twisted polyester yarn wound around the spandex yarn can strengthen the structure of the elastic weft yarn, and improve the durability and wear resistance of the entire fastener. Also, the double-twisted polyester yarn wound around the spandex yarn can increase the structural strength of the elastic weft yarn and maintain the elasticity of the spandex yarn in a stable state, thereby avoiding excessive elasticity or insufficient elasticity. By using the double-twisted polyester yarn, the entire elastic weft yarn becomes smoother and stronger, and the jamming of the fastener during opening and closing can be reduced.

[0014] In a relatively preferred case, the plurality of warp yarns of the elastic fastener are arranged side by side from left to right. The elastic weft yarn alternately passes through the tip and end of the plurality of warp yarns from left to right and twists to form a right elastic U-turn portion. Subsequently, the elastic weft yarn alternately passes through the tip and end of the plurality of warp yarns from right to left and twists to form a left elastic U-turn portion. Subsequently, the elastic weft yarn again alternately passes through the tip and end of the plurality of warp yarns from left to right and twists to form a right elastic U-turn portion. By repeating the above steps until the end, the finishing knot is knitted. That is, since the elastic weft yarn twists alternately, the tension distribution of the fastener becomes uniform in the weaving process, and damage and instability caused by excessive stretching or deformation in a part can be effectively avoided.

[0015] In a relatively preferable case, the engaging teeth of the elastic fastener are composed of a root portion and a tooth portion. The root portion is connected to the tape body. The tooth portions are arranged to mesh with each other to provide the opening and closing function of the fastener.

[0016] In a relatively preferable case, the elastic fastener further has a slider. The slider is arranged between two opposing tape bodies and meshes the engaging teeth to provide the opening and closing function of the fastener.

[0017] To sum up the above, since the elastic weft yarn provides good elasticity to the tape body, the fastener can not only maintain the stability of the overall shape and structure even when pulled or compressed, but also will not be excessively deformed and broken. When pulling and opening / closing the fastener, the elasticity of the fastener for travel bag can make the fastener open and close more smoothly. At the same time, when the slider bends or passes through a non-linear part, the sliding of the slider can be prevented from being obstructed, and the deviation of the engaging teeth can be suppressed. In addition, since the elastic weft yarn and the warp yarn are woven alternately, the structure of the tape body is tight and strong.

Also, the following detailed description and the embodiments presented by the present invention are only examples for explaining the present invention, and it should be understandable to those with common sense in the field related to the present invention that the claims of the present invention cannot be limited.

BEST MODE FOR CARRYING OUT THE INVENTION

[0020] Hereinafter, a fastener for a travel bag according to the present invention will be described with reference to the drawings. Note that the technical features of the present invention are not limited to the description of the following embodiments. In the specification, explanations and terms related to technology should be understandable to those with common sense in the field related to the present invention.

[0021] In this specification, "connection" includes a broad meaning. For example, in addition to fixed connection, detachable connection, and integral connection, it also includes mechanically or electrically connecting, directly connecting, or indirectly connecting through an intermediate medium. For those skilled in the art, the specific meaning of the above terms disclosed according to the embodiments of the present invention can be understood according to specific situations.

[0022] In this specification, unless otherwise specified and limited, the first feature being "above" or "below" the second feature means that the first feature and the second feature are in contact with each other or the first feature and the second feature are indirectly in contact with each other through an intermediate medium. Further, the first feature being "above", "upward", and "uppermost" of the second feature may mean that the first feature is directly above or obliquely above the second feature. Or it may simply mean that the first feature is at a higher level than the second feature. The first feature being "below", "directly below", or "right below" the second feature may mean that the first feature is directly below or obliquely below the second feature. Or it may simply mean that the first feature is at a lower level than the second feature.

[0023] In this specification, terms such as "one embodiment", "some embodiments", "example", "specific example", or "some examples" mean that the specific features, structures, materials, or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described can be combined in any suitable way in any one or more embodiments or examples. Furthermore, those skilled in the art related to the technology of the present invention can combine or associate different embodiments or examples described in this specification, and the features of different embodiments or examples without contradiction to each other.

[0024] (First Embodiment) As shown in FIG. 1, the fastener for travel bag according to the first embodiment of the present invention includes a first shell 1 and a second shell 2 that are connected facing each other, and an elastic fastener 3 that is separately connected to the first shell 1 and the second shell 2 and meshes with each other.

[0025] As shown in FIG. 1, the first shell 1 and the second shell 2 are combined to form a travel bag.

[0026] As shown in FIG. 2, the elastic fastener 3 has two or more opposing tape bodies 30, engaging teeth 40, and a slider 70. Each tape body 30 has one or more horizontal weft units 31 and a plurality of vertical warp threads 32. The weft unit 31 has elastic weft threads 311. The elastic weft threads 311 are bent along the length direction of the warp threads 32 and are alternately woven with the tip and end portions of the warp threads 32. The engaging teeth 40 are arranged on the elastic weft threads 311. The slider 70 is used for opening and closing the fastener. Specifically, since the elastic weft threads 311 provide good elasticity to the tape body 30, the fastener can not only maintain the stability of the overall shape and structure even when pulled or compressed, but also will not be excessively deformed and damaged. When the fastener is pulled to open and close, the elasticity of the elastic fastener 3 allows the fastener to be opened and closed more smoothly. At the same time, when the slider 70 bends or passes through a non-linear part, it is possible to suppress the situation where the cloth part of the fastener is excessively pulled, interfering with the sliding of the slider 70 and causing the engaging teeth to deviate. Also, since the elastic weft threads 311 and the warp threads 32 are alternately woven, the structure of the tape body 30 is tight and strong.

[0027] The elastic weft threads 311 of the elastic fastener 3 have spandex threads and double-twisted polyester threads wound around the outer peripheral wall of the spandex threads.

[0028] The plurality of warp threads 32 of the elastic fastener 3 are arranged side by side from left to right. The elastic weft threads 311 alternately pass through the tip and end portions of the plurality of warp threads 32 from left to right, bend and wind around to form a right elastic U-turn portion 315. Subsequently, the elastic weft threads 311 alternately pass through the tip and end portions of the plurality of warp threads 32 from right to left, bend and wind around to form a left elastic U-turn portion 316. Subsequently, the elastic weft threads 311 again alternately pass through the tip and end portions of the plurality of warp threads 32 from left to right to form a right elastic U-turn portion 315. Repeating the above steps until the end will knit the finishing knot. That is, since the elastic weft threads 311 alternately bend and wind around, the connection between the elastic weft threads 311 and the warp threads 32 is maintained in a stable state, providing relatively good elasticity in the horizontal direction to the fabric.

[0029] The engaging teeth 40 are composed of a root portion 41 and a tooth portion 42. The root portion 41 is connected to the tape body 30. The tooth portions 42 are arranged to mesh with each other.

[0030] The slider 70 is arranged between two opposing tape bodies 30 and meshes with the engaging teeth 40 of the tape bodies 30.

[0031] (Second Embodiment) FIG. 3 is a schematic diagram showing a fastener for a travel bag according to the second embodiment of the present invention. The differences from the above-described embodiment are as follows.

[0032] In the second embodiment, the weft unit 31 of the elastic fastener 3 further has one or more non-elastic wefts 312. The non-elastic wefts 312 are arranged between the elastic wefts 311 and the engaging teeth 40, bend along the length direction of the warp 32, and are alternately woven with the tip and end portions of the warp 32, and at the same time, alternately connect the bent portions of the elastic weft 322 and the engaging teeth 40. Specifically, the non-elastic wefts 312 alternately connect the engaging teeth 40 and the elastic wefts 311, and at the same time firmly fix the engaging teeth, reducing the risk that the engaging teeth 40 loosen or deviate under external force, enhancing the reliability and service life of the fastener, and ensuring that the tooth portions of the engaging teeth 40 are aligned. When the slider 70 passes through a bent or non-linear portion, the elastic weft 311 can be prevented from being obstructed by the slider 70. In the second embodiment, the engaging teeth 40 and the non-elastic wefts 312 are interconnected by a sewing machine. The non-elastic wefts 312 alternately pass through a plurality of warps 32 to form a left non-elastic U-turn portion 313 on the left side and a right non-elastic U-turn portion 314 on the right side. The left non-elastic U-turn portion 313 and the right non-elastic U-turn portion 314 are alternately woven. Since the engaging teeth 40 are sewn into the right non-elastic U-turn portion 314 by a sewing machine, the stability and durability of the elastic fastener 3 can be improved. Also, the method of sewing the engaging teeth 40 into the right non-elastic U-turn portion 314 by a sewing machine can firmly fix the engaging teeth 40 to the tape body 30 and prevent them from deviating from the tape body 30.

[0033] (Third Embodiment) FIG. 4 is a schematic diagram showing a fastener for a travel bag according to the third embodiment of the present invention. The differences from the above-described embodiments are as follows.

[0034] In the third embodiment, the elastic fastener 3 has a non-elastic side protection member 50 between the elastic weft yarn 311 and the duty teeth 40. One side of the non-elastic side protection member 50 is connected to the duty teeth 40, and the other side is connected to the elastic weft yarn 311. Specifically, the non-elastic side protection member 50 is a non-elastic member that covers the side. The duty teeth 40 are arranged so as to fit into the side far from the elastic weft yarn 311 of the non-elastic side protection member 50. The elastic weft yarn 311 and the non-elastic side protection member 50 are connected to each other by a sewing machine. The non-elastic side protection member 50 supports the duty teeth 40, increases the connection strength between the duty teeth 40 and the tape body 30, and at the same time suppresses the duty teeth 40 from loosening or deviating under an external force, and can improve the stability of the entire fastener.

[0035] As described above, the present invention is not limited to the above-described embodiments, and can be implemented in various forms without departing from the spirit of the invention.
