Definitions
- the present invention generally relates to slide fasteners. More particularly, the present invention relates to fastener elements. Stringers made with the fastener elements of this disclosure can be used for either hidden slide fasteners or slide fasteners where the elements remain visible from the outside.
- a slide fastener includes a flattened pair of tapes.
- the fastener tapes each generally have an inwardly facing edge on which cords are formed, and fastener elements (or teeth) are attached to the cords and the inner edge of the fastener tape. The elements are forced together when their edges are drawn together by the action of the slider on each element.
- a tape to which elements are attached in this manner is known as a stringer.
- Two stringers when joined together are known as a chain.
- Slide fasteners generally include a chain and at least one slider, and often have a top stop, a bottom stop, or both attached to the chain. When the slide fastener is opened and closed, the user typically holds a puller linked to the slider and pulls the slider forward or backward. This causes the slide fastener to close or open depending on the direction of travel of the slider.
- the present invention relates to a fastener element that shares several features in common with conventional fastener elements used in concealed slide fasteners.
- the front or back of the chain of slide fasteners can be exposed.
- the elements are discretely attached to the stringer, i.e. individual elements made of metal or plastic, are for example crimped (common in the case of metal) or alternatively injection molded (plastic).
- crimped common in the case of metal
- plastic plastic
- the slide fastener when the slide fastener includes a continuous element, i.e., when the element of stringer sewn to the edge of the tape includes a coil or spiral, the element may be fully attached to either the outwardly or inwardly facing side of the tape. may be placed in Even in this situation it is possible to see them when the elements are placed on the inward facing side of the slide fastener. By folding the tape over successive elements and sewing in place, more complete concealment of the elements is possible. Concealed slide fasteners of this type are well known in the art. It is possible to use techniques similar to stringer tape turns with elements that are discretely attached to the tape. Generally, the elements of this type of slide fastener are not exposed, i.e.

- the engagement projections and engagement recesses are configured to mate with engagement recesses and engagement projections, respectively, provided on two respective fastener elements fitted on the opposing stringers.
- the slider moves smoothly in one direction, but less smoothly in the opposite direction.
- the present invention provides a slide fastener element that forms a high quality slide fastener along which a slider can move smoothly in either direction both when closing the slide fastener and when opening it. for the purpose.
- Another object of the present invention is to form a slide fastener with a striking metal element that has a shiny metallic appearance.

- the root forms a major arcuate groove (ie, a groove shaped as an arc having a size greater than or equal to 180 degrees) for receiving and retaining a length of cord and an edge of the fastener tape.
- the joint has two opposing faces along its length.
- Each face of the coupling portion has a longitudinally projecting engaging projection and an engaging recess longitudinally recessed with respect to the associated face such that when the slide fastener is closed, the fastener element on the opposing stringer is configured to receive the engagement projection of the
- the root portion of the fastener element in its undeformed state prior to attachment to the tape, is substantially straight and has not yet formed said arcuate groove.

- the pitch between two fastener elements on the same stringer is reduced relative to the prior art, thereby making the gap between two consecutive elements shorter, in other words, the The top elements are closer together. Due to the fact that the elements are more tightly fitted, the visible surfaces of the elements of the slide fastener have a more uniform, shiny metallic appearance. This aesthetic effect can be desirable when the slide fastener is not used as a concealed slide fastener.

- the tip 18 of the distal end 17 of the root 14 can extend laterally closer to the distal edge 28 of the joint 13 .
- tip 18 may lie in a longitudinal plane D extending across engagement recess 26 .
- This arrangement results in a narrowing of the gap G between the longitudinal planes in which the opposing tips 18 of the two rows of elements lie.
- a narrow gap G advantageously limits rotational movement between the left and right stringers, thereby preventing undue separation of the two stringers in the engaged state of the slide fastener.
- plane D lies between longitudinal planes E and F that bound recess 26 laterally between connecting wall 32 and ridge 53 of engaging projection 25 .
