SLIDE FASTENER

摘要

(Object) To provide a slide fastener with a novel function enabling the slide fastener to be used in a way of dividing one space into four spaces orthogonal to one another, by creating a fastener element having a specific shape based on a novel idea. (Solution) The slide fastener comprises elements, which are arranged in a line along each of oppositely-positioned edges of opening/closing ends of horizontal fastener tapes, and a slider, the slide fastener including a horizontal functional section for dividing one space into two spaces and a vertical functional section for dividing each of the two spaces, divided by the horizontal functional section, into two spaces with one operation by sliding the slider along the elements, wherein the horizontal functional section includes element heads which are meshed with and unmeshed from each other with the sliding of the slider along the elements, and horizontal fastener tapes which are opened and closed in a horizontal direction corresponding to meshing and unmeshing of the element heads, and wherein the vertical functional section is extended upwards and downwards in a vertical direction perpendicularly to the horizontal functional section and includes upper element legs which are formed by extending portions of the elements upwards in the vertical direction and by bending the extended upper portions into a hook-like shape, upper holding portions formed by distal ends of the upper element legs coming close to and moving away from each other in conjunction with the meshing and the unmeshing of the element heads, an upper vertical fastener tape which is engageable in the upper holding portions for selective opening/closing in the vertical direction on an upper side, lower element legs which are formed by extending portions of the elements downwards in the vertical direction and by bending the extended lower portions into a hook-like shape, lower holding portions formed by distal ends of the lower element legs coming close to and moving away from each other in conjunction with the meshing and the unmeshing of the element heads, and a lower vertical fastener tape which is engageable in the lower holding portions for selective opening/closing in the vertical direction on a lower side.
