Definitions

  • this known slide-fastener also possesses other significant advantages, such for example as that the metallic slider hooks are protected from weather influences, and in view also of other advantages, especially where the slide-fastener is used on suitcases, bags, and the likethe protection of the slide fastener elements from the effects of external impacts and other sources of injury owing to the double screening of the slide fastener elements-it is reasonable to expect that such slide-fasteners will be used in large numbers and be frequently manipulated.
  • This fact prompted the inventor of the said known slide-fastener to devote special attention to ensuring that the aforesaid slide-fasteners are able to stand up to the most diversified stresses and can be operated easily and without hitch even by the most clumsy of persons.
  • the inventive design of the slide-fastener is also fully reliable in service in the sense that the slider does notas occurs in ordinary slide-fastenerschafe through the woven supporting tape outside of the slidefastener elements.
  • the inventive design avoids any contact between the parts of the slider on the one hand and the supporting tape, or the material attached to the latter, on the other. This is above all due to the fact that the central abutment of the slider is positioned at an adequate distance from the supporting tapes, i. e., from the material of the garment, etc., in every position of engagement.
  • the central abutment is isolated and in the slide-fasteners for practical use manufactured according to the invention is located at a distance of about two or more millimetres fromthe selvedges of the material).
  • the interlocking of the slide-fastener elements has been improved by an elongated rectangular shape being chosen for the engaging projections and recesses proper, the plane of the rectangle being perpendicular to the plane of the supporting tapers, i. e., of the material. This shape reliably prevents the unhooking or tilting of the slide-fastener elements.
  • Figure 1 is a sectional view through a slide-fastener according to the invention, in the closed condition, with pieces of material attached by stitching;
  • Figure 2 is a sectional view through the slider
  • Figure 3 is a plan view of the slider
  • Figure 4 shows a slide fastener in accordance with the invention, in the semi-closed condition.
  • Figure 1 shows the inwardly directed projection of the hook-shaped supporting element.
  • the projection 1 places itself in the hollow or throat 3 located between the thickening 4 and the supporting tape 5.
  • the projection 1 acts as an additional clamping device and ensures that the heaviest stresses which are likely to occur during the manipulation of the slide-fastener, and in particular such stresses as are provoked by guide-shoulders or guidecheeks-to be discussed hereunderof the central abutment of the slider, are accommodated with certainty.
  • Figure 1 Another essential detail illustrated by Figure 1 is the elongated rectangular form 6 of the projections and recesses of the slide-fastener elements.
  • the longitudinal axis I of the said engaging projections and recesses is perpendicular to the plane of the supporting tapes, i. e., to the pieces of material sewn thereto.
  • the aforementioned guide-shoulders or guide-cheeks are indicated by the numeral 7 in Figures 2 and 3. They are provided at a suitable level on the central abutment 8 of the slider for engaging the top surfaces of the inner ends 2 of the fastener elements to guide them into or out of engagement in proper relation when the slider is moved longitudinally of the fastener tapes 5.
  • the guide-shoulders or guide-cheeks provided on the so-called closing triangle 9 converge, as is clearly shown in Figure 3, towards the tip of the triangle and at the same time progressively diminish in crosssection; they practically merge into the tip.
  • the cross-sectional shape of the said guide-cheeks is preferably convex or rounded, as shown in Figure 2.
  • the said guide-cheeks act similarly to threading tongues, since they contact the fastener elements and ensure that the entering and emerging slidefastener elements engage and disengage at the desired point.
  • the invcntors numerous experiments have revealed that the manipulation of a slide-fastener equipped with such a slider takes place without hindrance of any kind from the material of cloth, and practically without effort.
  • slide-fastener In the closed condition the slide-fastener is, as is shown in Figure 4, completely invisible to the external observer.
  • the pieces of material attached to the slide-fastener close up against one another as though they were attached to one another by a real seam. It is obvious that it is now not necessary, as it formerly was, to select, for the assembly of the slide-fastener, slide-fastener elements of as. inconspicuous a size as possible. It is now possible to use more amply dimensioned slide-fasteners, without this fact being observable from the exterior. It is, therefore, no longer necessary to keep in stock slide-fasteners of the most varied colours.
  • a slider including a body member having a triangular central guide abutment projecting upwardly therefrom having a pair of side walls converging in one direction longitudinally of the body member substantially to a first point for guiding the inner ends of the fasteners into and out of interlocking engagement, a pair of outer flanks extending upwardly from said body for engaging and guiding the outer ends of said fasteners and causing the inner end
  • a slide fastener constructed in accordance with claim 1, wherein said guide shoulders have their outer projecting edges arcuately rounded.
  • a slide fastener constructed in accordance with claim 1 wherein said outer ends of said fasteners are arcuate about a center line extending generally parallel to the longitudinal axis of the series of fasteners and wherein said outer flanks are substantially cylindrical longitudinally of the slider for snugly cooperating with the arcuate outer ends of the fasteners, and wherein said flanks are outwardly flared at the ends of the slider.
  • a slider including a body member having a triangular central guide abutment projecting upwardly therefrom having a pair of side walls converging in one direction longitudinally of the body member substantially to a first point for guiding the inner ends of the fasteners into and out of interlocking engagement, a pair of outer flanks extending upwardly from said body for engaging and guiding the outer ends of said fasteners and causing the inner end of said fasteners
