Abstract
Description
Technical Field
[0001] This application claims the priority of a Chinese patent application filed with the China National Intellectual Property Administration on July 19, 2022, with the application number 202221868841.0 and the utility model name "Pressureless Slider and Fastener", and all of its content is incorporated herein by reference.
[0002] This application relates to the technical field of fasteners, and particularly to pressureless sliders and fasteners.
Background Art
[0003] As an important component of clothing accessories, fasteners are widely applied to daily necessities such as clothes, backpacks, and tents.
[0004] As is well known, in a fastener, through properly arranged elements, the functions of closing or separating are achieved by the action of a slider. Generally, a fastener includes components such as tapes, elements, sliders, upper stops, and lower stops. A normal fastener has tapes on both sides, and each tape is provided with a row of elements. The two rows of elements are arranged in a staggered pattern to achieve a fixing effect. When the slider slides, the elements on both sides engage with or disengage from each other.
[0005] In the prior art, sliders are generally made of alloy materials. When used on backless clothes, since the fastener often comes into contact with the skin, a foreign body sensation may occur, which may also cause pain or coldness, resulting in a poor wearing experience. In view of this, in order to avoid contact with the skin during wearing, how to redesigned the slider is a technical problem that those skilled in the art must consider.

Mode for Carrying Out the Invention
[0021] Hereinafter, in combination with the drawings of the embodiments of the present invention, the technical solutions of the embodiments of the present invention will be clearly and completely described. The described embodiments are only some, rather than all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained on the premise that those skilled in the art do not make inventive labor belong to the protection scope of the present invention.
[0022] In order for those skilled in the art to better understand the solutions of the present invention, the present invention will be further described in detail below in combination with the drawings and specific embodiments.
[0023] Regarding the pressureless slider 1 provided by an embodiment of the present application, referring to FIGS. 1 to 8, the pressureless slider 1 includes a core 11, a base 12, two side baffles 15 and two side bottom plates 16.
[0024] The pressureless slider 1 opens and closes with respect to the element 2 to realize the opening and closing of the fastener. The element 2 is sewn to the tape 4, and a cylindrical cord 3 is provided. The end of the tape 4 approaching the element 2 has a tape bending portion 41, and the tape bending portion 41 is bent in the direction toward the element 2.
[0025] The two side baffles 15 are respectively located on both sides of the core 11. Together with the core 11, they form the side walls of the passage for introducing the element 2. The base 12 is provided on the bottom end face of the core 11, and both sides thereof extend along the directions toward different side baffles 15 respectively. The two side bottom plates 16 are respectively provided on the bottom end faces of different side baffles 15 and extend along the direction toward the base 12. The two side bottom plates 16 are in close contact with the tape 4 and have a step with the base 12. There is a gap between the base 12 and the tape 4. The two side bottom plates 16 and both sides of the base 12 form the bottom end of the passage.
[0026] By setting the pitch between the base 12 and the side bottom plate 16 to 0.05 - 0.2 mm, the best use effect can be achieved. Setting the pitch between the base 12 and the side bottom plate 16 to 0.1 mm is the most ideal. Thereby, the pressureless feeling can be maximally improved and normal use can be ensured, and when in use, it can avoid biting the fabric.
[0027] When in use, the pressureless slider 1 is surrounded by the tapes 4 on both sides of the element 2. The two side bottom plates 16 are blocked by the tapes 4, and only the core 11 is exposed. Since the base 12 of the core 11 is lower than the two side bottom plates 16, the exposed base 12 is also lower than the tapes 4 on both sides. Thereby, the only exposed core 11 does not contact the skin, achieving the effects of no pressureless feeling and no pain.
[0028] As a preferred arrangement, the base 12 and the two side bottom plates 16 are arranged in parallel. When in use, the side bottom plates 16 are in close contact with the tape 4, and a certain pitch is maintained between the base 12 and the tape 4 to further ensure that they do not contact the skin, thereby improving the use effect. The two side bottom plates 16 may further be provided on the same surface. When the two side bottom plates 16 are in close contact with the tape 4, the flatness of the tape 4 is ensured to avoid wrinkles on the tape 4.
[0029] Continuing to refer to FIG. 1, upper plates 14 are further provided on both sides of the core 11. The two upper plates 14 are respectively connected to different side baffles 15, and the upper plates 14 form the tips of the passages. As can be seen from this, a semi-closed passage for the element 2 to pass through is formed by being surrounded by the core 11, the base 12, the upper plates 14, the side baffles 15 and the side bottom plates 16.
[0030] Both sides of the base 12 and the edges of the two side bottom plates 16 are installed in an arc shape, so as to avoid the element 2 being caught when in use, reduce stress concentration, and extend the service life of the pressureless slider 1.
[0031] In some embodiments, the core 11, the base 12, the two side baffles 15 and the two side bottom plates 16 are integrally formed and arranged. For example, they are manufactured to be integrally injection molded, thereby improving the structural strength of the pressureless slider 1 and ensuring reliable use.
[0032] The end of the core 11 extends from the outer edge of the upper plate 14 to the side away from the base 12 of the upper plate 14. The end of the core 11 may be regarded as wrapping both sides of the upper plate 14, effectively improving the connection strength between the core 11 and the upper plate 14, and ensuring the reliable use of the entire pressureless slider 1.
[0033] A handle 17 is rotatably provided on the upper plate 14. The handle 17 is located on the side of the upper plate 14 away from the base 12. By pulling the handle 17, the entire pressureless slider 1 moves relative to the element 2 to realize the opening and closing actions on the element 2.
[0034] The fastener provided by this application and including a pressureless slider includes the pressureless slider described in the above specific embodiments. For other parts of the fastener, reference may be made to the prior art, and this is not elaborated in this specification.
[0035] Here, in this specification, relational terms such as first and second are merely used to distinguish one entity from several other entities, and it is not necessarily required or implied that there is such an actual relationship or order between these entities.
