Description
Technical Field
The present invention relates to a slide fastener generally applied to a vacant site of a braid for controlling opening or closing of the vacant site. The invention relates to a zipper with a light sliding effect.
Background
Slide fasteners are common in everyday life and generally comprise an axially extending left zipper strip, a right zipper strip and an axially sliding slider by means of which sliding the elements on the left and right zipper strips can be mutually engaged or disengaged. The existing fastener elements are generally integrally formed rigid structures, such as cold extrusion formed metal fastener elements or injection molded resin fastener elements, and the left fastener elements of the left fastener tape and the right fastener elements of the right fastener tape are all extruded by the pull head to be matched with each other in a concave-convex manner to be meshed together in the process of pulling and combining the left fastener tape and the right fastener tape. The left element and the right element require relatively large pressing forces to be able to mesh together due to the influence of the associated dimensional accuracy of fit. And the pull head can generate certain friction force with the zipper teeth or the cloth belt in the sliding process. The existence of the factors can influence the closing smoothness of the zipper, and the quality and effect of the product are influenced to a certain extent. In order to improve the light sliding property of the slide fastener, there are proposed some solutions, such as an elastic engagement slide fastener in chinese patent No. CN201410348920.2 improved in terms of element structure, a hook-shaped dislocation tooth injection slide fastener in chinese patent No. CN200410030762.2, or a slider for reducing friction with the element in chinese patent No. CN201620244875.0 improved in terms of slider structure. However, in many of the above solutions, the problem that the sliding property is affected by the resistance generated by the mutual extrusion between the fastener element and the slider cannot be solved well. The inventor found that a safety slide chain capable of solving the above problems well is provided in chinese patent No. CN201410658506.1, which includes a top chain body and a bottom chain body. The upper chain body comprises a plurality of clamping rings arranged on the base cloth, the clamping rings comprise two arc-shaped clamping arms which are connected into a whole, and the end parts of the clamping arms are spherical. The lower chain body comprises a strip-shaped chute and a base cloth connecting seat arranged at the lower end of the chute, the chute is an inverted trapezoid chute, protruding ribs are arranged on four edges of the chute, protruding ribs at the top end of the chute extend out of the outer end of the chute and are provided with limiting tables, the protruding height of each protruding rib at the top end of the chute is larger than that of protruding ribs at the other three edges, the base cloth connecting seat is connected with the base cloth, and the upper chain body is clamped on the protruding ribs of the chute through clamping rings so as to be connected with the lower chain body. The scheme omits the setting of the pull head completely, so that the extrusion friction of the pull head to the sprocket can be avoided completely. The safety slide chain is not suitable for controlling the opening or closing of the vacant part of the braid, and does not substantially have the function of a conventional slide fastener.
