Definitions

  • This invention relates to sliders for use in coupling and uncoupling separable fastener stringers. More particularly, the invention deals with devices of this kind employing a spring actuated locking finger adapted to be normally held in engagement with the scoops of at least one Stringer of the fastener to retain the slider against accidental opening movement. Further, the in.
  • Fig. 1 is a side view of a part of a fastener with my improved lock slider thereon, part of the construction -being broken away and in section.
  • Fig. 2 is a section on the line 2-2 of Fig. 1 showing part of the slider in elevation and diagrammatically illustrating one scoop on one Stringer tov indicate the locking engagement.
  • Fig. 3 is a section on the line 3 3 of Fig. 2 i
  • Fig. 4 is a partial section on the line 4-4 of Fig. 2, omitting part of the showing in Fig. 2.
  • Fig. 1 I have shown at I and Il a portion i of two stringers, upon the beaded edges I2 and i3 of which are arranged longitudinally spaced scoops I4.
  • the scoops I4 are of the coreless type and comprise scoop bodies of V-shaped cross-sectional form to provide longitudinal channels l5 at the upper surfaces thereof and longitudinal ridges I6 at the lower surfaces thereof, as indicated in Fig. 2 of the drawing. 'This formation of the scoops retains the scoops against transverse separation; whereas the scoops have upper and lower transverse projections I1 at the outer ends thereof, inwardly of which are upper and lower recesses I3, note Fig. 1, to couple the scoops against lateral or pull-apart separation.
  • the slider is in the form of a more or less conventional body defined by upper and lower walls 20 and 2l joined at one end by a connecting web 22.
  • have inturned side flanges, as indicated at 23 in Fig. 3 of the drawing.
  • the outer surface of the top wall 20 oi.' the slider has, at the end portions thereof. substantially U- shaped recesses 24 and 25, to receive the outwardly flanged ends 26 and 21 of a pull support-4 ing bar 28arranged centrally and longitudinally of the slider.
  • the bar 2B has a channel portion 29, the side walls of which are recessed, as seen at 30, to receive the cross-head end 3l of a pull, the recesses 30 being sufficiently long to permit substantial longitudinal movement of the pull with respect to the bar 28.
  • the flanged end 21 of the bar 23 ha's, on its inner surface, an enlargement 32, in which is formed a recess 33 for the reception of a coil spring 34.
  • the spring is adapted to bear on the end 35 of alock finger 36 directly above an aperture 31 formed in the finger.
  • the upper surface of the wall 20 has a projecting knob-33 arranged in the aperture 31 to key the end of the finger in position on the wall 2li.
  • the enlarged portion 32 also has a downwardly extending projection 39 which rests upon the end portion 35 of the finger to aid in supporting the finger in engagement with the wall 20 and, further, to form what might be termed a pivot on which the finger can swing in movement into operative and inoperative positions.
  • the central portion of the nger 36 has angularly disposed portions forming two camming surfaces 40 and 4I adapted to be engaged by the cross-head 3
  • the offset end 42 passes downwardly through an aperture 43 in the top wall of the slider, as clearly seen in Fig. 3 of the drawing, so that the end 42 can normally extend into the channel of the slider to engage the scoops disposed therein.
  • the inturned flanges '44 bordering the recesses 24 and 25, in the manner illustrated in the drawing, are formed after the bar 28 is arranged in position in said recesses.
  • this is accomplished by simply forming a straight walled recess and then turning the flanges 4I inwardly in the manner which is clearly illustrated in Fig. 4 of the drawing to engage the flange portions 26 and 2l of the bar 28.
  • the pull supporting bar is not formed as an integral part therewith, but rather as a separate member attached to one wall of the slider in the manner described.
  • This type oi' construction also facilitates assemblage of the pull with the slider, as compared with devices where the bar constitutes an integral part of the slider wall.
  • spring means on the slider for yieldably supporting said element intermediate the ends thereof in a scoop-engaging position, means .in the housing for pivotally supporting the thinned end of the element, and manually operated means on the slider for moving said element out of scoop-engaging position.
  • an improved lock slider comprising a lock element supported on the slider, a housing for said lock element, said element having a curved scoop-engaging end adapted to enter the channel of a scoop to retain the slider against movement in one direction along said stringers, means on the slider for keying the element thereto intermediate the ends of the element, spring means on the slider for yieldably supporting said element at said keying point in a scoop-engaging position, means in the housing i'or pivotally supporting the other end of the element, and manually operated means on the slider' for moving said element out of scoop-engaging position.
