Definitions

  • the slider for example for overcoming jamming when-the slider may: have jammed on the stringers;
  • the riser element 5 has a pivot hole 8 and a bore 24 at right-angles thereto, both parallel to the base of the shield 1, and the bore 24 extending in the longitudinal direction of the shield 1.
  • the bore 24 is blind at one end adjacent the wedge-shaped portion 6 and open at its other end adjacent the tail portion 10 of the riser element 5.
  • the side walls 3 and 33 of the shield I extend from the narrow end of the shield to about half way along the shield.
  • the riser element 5 is unitary with the base and extends generally in the longitudinal direction of the base from the wide end of the shield 1, towards about the centre thereof.
  • the retaining plate 7 is parallel to the base and spaced therefrom substantially by the width of the interlocking mem'bers 21(that is to say, the dimension of the said members perpendicular to the plane of-the tapes 29, 30), the retaining plate 7 extending laterally from and beyond the wedge-shaped portion 6 of the riser element 5.
  • the slider .shield 2 has a narrow end and a wide end, and is provided with a longitudinal substantially central aperture 12 bordered towards the narrow end by an edge 23.
  • An additional aperture 16 is formed by an extension of one corner of aperture 12 towards one side and towards the narrow end of the shield 2. .At its wide end, the shield 2 is provided, adjacent the aperture 12,
  • Fig. 1 is a p-erspective vie'w'of a portion of a sliding clasp fastener comprising a slider of the invention
  • Fig. 2' is a view similar to Fig. l, but showing the slider shields spread apart, and one of the. fastener stringers retained by the -slider while the other stringer is removed from the slider;
  • Fig. 3 is an exploded perspective view of Fig. 4 is a side view of'the assembled slider, partly'in section, and to a larger 'scale than Figs. 1 to 3, showing the slider in its closed'position;
  • f I 1 -Fig. 5 is aside view similar to t-hatof Fig.4, and to the same scale, but with the slider shields spread apart;
  • Pig. 6 is a sectional'inverted view along the line VI-Vl: ofFig. 4;and
  • FIG. 7 is a sectional view Fig. 4.'-
  • the sliding clasp fastener shown in Figs. prises two stringers generally indicated by reference numerals 22 and 28.
  • the stringers 22 and 28 respectively comprise c-arrier' tapes 29 and 30, provided with interlocking members 21.
  • the fastener is opened and closed in known manner by a slider generally in'dicate'd platf0mi35,and a retaining plate 7. 5
  • the pull member 17 has pivot pins 19, an abutment portion 18, and a locking projection 20.
  • the spring 11 is a helical compression spring.
  • the spring 11 is introduced into the 'bore 24 so that the greater part of the spring 11 is housedin the said bore 24.
  • the shield 2 is placed over, the. riser element f the shield 1 so that the spring llvicontacts the spring abutment face 13 of the shield.
  • the shield 2 isdisplaceable relatively to. the other, shield l andthe; riser element 5" against' the action 613; the spring 11, this displacement being possible without” the shield 2 being moved out of its'positionjof parallel relationship with the shield 1.
  • the shield 2 is no longer constrained to remain parallel to the shield 1, and can be spread apart from the shield 1 by turning'the shield2relatively to the shield 1 about the fulcrum portion 25, which 'although displaced in the longitudinal direction.
  • the shield 2 Since the shield 2 is no longer constrained by the overhanging portion 9 of the riser element 5 the shield 2 is caused to pivot about the fulcrum portion 25, which rests on the platform 35, so that the narrow end of the shield 2 recedes from the narrow end of the shield 1, the spreading being permitted by a clearance between the bevelled face 26 of the shield 2 and the platform 35 of the riser element 5.
  • the amount of spreading is limited by the outer face of the shield 2 abutting against the pull member 17.
  • the position of the slider when its shields 1 and 2 are fully spread is shown in Figs. 2 and 5.
  • the retaining plate, 7 prevents the stringer 22 (see Figs. 1 and 2) from being removed from the slider. This prevention is achieved by arranging the retaining plate 7 so that it extends towards the narrow end of the shield 1 past'the diverging end of the sidewall 33 of the slider shield 1. slidably move' in the channel formed by the shield 1, side wall 33, and the retainingplate7, but cannot be separated from thetslider.
  • a slider for a sliding clasp fastener comprising two "opposed slider shields for guiding two fastener stringersfthrough the slider, a riser element provided in fixed position on one of said slider shields and extending through. an aperturein the other slider shield, a support on said riser element, the said support carrying said other slider shield displaceably in substantially parallel relationship to said one slider shield, a portion on said riser element, the said portion normally overhanging an edge of said other slider shield bordering the said aperture, an abutment on said 'other slider shield, spring means acting between the saidabutmen't and' the said' riser element, the said spring means urging the said edge into a position underneath the said overhanging portion, and fulcrum means on the said other shield,
  • the arrangement being such the spreading of the slider shields relatively to each other is effected by first displacing the said other shield along said support to clear the said overhanging portion so that the said other .shield is no longerconstrained to remain in the same and having an abutment surface arranged for co-opera-- tion with a surface of said-abutmentof said other shield,
  • the arrangement being such that, on pressing the said surfaces together by turning the pull member, a camming.
