Description

Light sliding zipper and products using the same

technical field

The present application relates to the field of clothing accessories, in particular to a light sliding zipper and a product using the same.

Background technique

The zipper is relatively common in daily life, and generally includes an axially extending left zipper tape, a right zipper tape and an axially sliding slider. The chain elements engage or disengage from each other. Most of the existing fastener elements are integrally formed rigid structures, such as cold-extruded metal fastener elements or injection-molded resin fastener elements. The slider presses the left fastener element of the left zipper tape and the right fastener element on the right fastener tape to make them fit together in a concave and convex manner. Due to the influence of the relative fitting dimensional accuracy, the left fastener element and the right fastener element require a relatively large pressing force to be able to engage together. In addition, the slider will also generate a certain frictional force with the fastener elements or the cloth tape during the sliding process. The existence of the above factors will affect the lightness and smoothness of the zipper, which will affect the quality and effect of the product to a certain extent. In order to improve the smoothness of the zipper, many solutions have been proposed at present, such as the elastic meshing zipper in the Chinese invention patent CN201410348920.2 which improves the structure of the fastener element, and the hook-shaped dislocation tooth in the Chinese invention patent CN200410030762.2. An injection-molded zipper, or a slider that reduces friction with the fastener elements in the Chinese utility model patent CN201620244875.0 which is improved in terms of slider structure. However, among the above-mentioned solutions, the problem of the resistance caused by the mutual extrusion between the fastener element and the slider and thus affecting the smoothness is still not well resolved.

The inventor of the present invention found that Chinese invention patent CN201410658506.1 proposes a safety sliding chain that can well solve the above problems, including an upper chain body and a lower chain body. The upper chain body includes a plurality of clamping rings arranged on the base cloth, the clamping rings include two arc-shaped clamping arms connected as a whole, and the ends of the clamping arms are spherical. The lower chain body includes an elongated chute and a base cloth connecting seat arranged at the lower end of the chute, the chute is an inverted trapezoidal chute, and four edges of the chute are provided with protruding ribs, The protruding rib at the top of the chute extends out of the outer end of the chute and is provided with a limiting platform. The height of the protruding rib at the top of the chute is greater than the height of the protruding rib on the other three edges. Connected with the base cloth, the upper chain body is clamped on the rib of the chute through the clamping ring so as to be connected with the lower chain body. This solution completely omits the setting of the slider, so that the extrusion friction of the slider to the sprocket can be completely avoided. However, the safety slide chain is not suitable for controlling the opening or closing of the opening portion of the woven fabric, and does not have the function of a conventional zipper substantially.
