Definitions

  • the present invention relates to slidersfor sliding clasp fasteners of the kind comprising opposed ⁇ shields for guiding two fastener stringers through the slider, the said shields being joined so as to allow spreading apart of the shields at any position of the slider on the stringers at which the slider may have jammed whereby to overcome the jamming.
  • AIt is still another object of the invention to provide a slider of the kind described, which comprises only three components which allow the slider to be easily assembled.
  • Fig. 1 illustrates a perspective view of a slider of the invention in position on two stringers of a sliding clasp fastener
  • Fig. 2 similarly illustrates the slider With the slider shields spread apart, the slider being detached from the fastener stringers;
  • Fig. 3 shows an exploded perspective View of the slider
  • Fig. -4 shows a side view of the slider
  • Fig. 5 shows a similar side view of the slider with the slider shields spread apart
  • Fig. 6 shows a plan view of the slider
  • Fig. 7 shows a plan view of -one of the slider shields.
  • the slider illustrated in the drawings Vcomprises two opposed slider shields -1 ⁇ and 12, and an operating tab 22.
  • the shields 1 and 12 will hereinafter be termed the lower and the upper shield respectively.
  • the lower shield 1 comprises a base 2, side walls 3, and a wedge-shaped projection 4.
  • the projection 4 forms part of a riser element generally denoted by reference numeral 5 and provided with two transverse bearing grooves 6 and 7 (see Fig. 3.), with a rib 7a providing a wedge 8 an'd'with faces 9 parallel with the base 2, the faces 9 extending from the bearing groove 6 towards the lgroove 7 4vand terminating in a vertical wall 10 (see also Figs. ⁇ 4, 5 "and 46) approximately underneath the lbearing groove 6.
  • the upper shield 12 comprises a base 13 and side walls 14 adapted to overlie the side walls 3 of the lower shield 1.
  • the base 2 of the lower shield 1, its side walls 3, the base 13 of the upper shield 12, its side walls 14 and the wedge-shapedA projection 4 are arranged to form, in known manner, diverging channels for the passage of interlocking members of two stringers 41 in connec- 2,855,651 Patented Oct. 14, 1958 ICC tion with which the slider is used.
  • the base 13 of the vupper shield 12 has a wide perforation 16 merging at ⁇ shoulders 19 into a narrow slot 15 open at 115 at the end of the upper shield overlying the wedge 8.
  • the upper shield 12 is forked, the limbs 17 of the fork being capable of being elastically forced apart from each-other in the general plane of the upper shield 12.
  • the slot 15 narrows still Afurther at so as to provide two Aopposed lateral projections 18. Between the opposed walls of the slot 15 are integral aligned hinge pins 20 which meet, or nearly meet, each other.
  • the tab 22 for operating the slider is a forking the portions 23 of which are bridged by a pivot pin 24, which may be formed in one piece with 'the forking.
  • the operating tab 22 as a whole may be formed by casting, moulding or stamping.
  • the portions 23 are formed with peripheral cam faces 25 substantially concentric with the axis of the pivot pin 24 and extending through approximately and terminating in a radial or nearly radial shoulder 26 forming a recess 27 with the surface 28 of the operating tab 22.
  • the operating tab has a locking finger 29 arranged for extending through the perforation 16 in the upper shield 1'2 and engaging ⁇ be tween adjacent interlocking members 40 for locking the slider in a desired position on the stringers 41.
  • the hinge pins 20 of the upper shield 12 are located in the bearing groove 6, the upper shield 12 resting with the limbs 17 in surface engagement with the faces 9, and with the lateral projections 18 in contact with the wedge 8.
  • One of each side wall of the bearing groove 6 is peened or turned over to retain the hinge pins 20 in the said bearing groove and to complete the bearing for the said hinge pins.
  • the pivot pin 24 of the operating tab 22 is then located in the bearing groove 7 and one or each side wall of the bearing groove 7 is also peened or turned over to retain the pivot pin 24 inthe said bearing groove and to complete the bearing.
  • Figs. l and 4 show the slider closed for normal use with the operating tab 22 in the position shown in Fig. l or shown in full lines in Fig. 4; the concentric faces 25 are in contact with, or in close proximity to, the adjacent part of the outer face of the upper shield v12, the said part acting as a stop face so that the shields 1 and 12 cannot hinge open about the hinge pins 20.
  • This stop action persists while for opening or closing the sliding clasp fastener the operating tab 22 is being turned through almost the Whole of its 180 movement until it reaches the position indicated in broken lines at 221 in Figs. 4 and 5 when the shoulders 26 terminating the concentric faces 25 pass beyond the shoulders 19 of the perforation 16 in the base 13 of the upper shield 12 and overlie the perforation 16.
  • the projections 18 rst move along the straight upright sidewalls of the rib 7a and subsequently along the wedge 8. As soon as the projections 18 have left the said side walls, the closing of the slider is completed with a snap action due to the elasticity of the limbs 17 forcing the upper shield 12 into its position for normal use.
