  • a slider retaining lever 15 Accommodated within the cavity. 14 is a slider retaining lever 15 having a wedge-shaped head portion 16 adapted to be thrusted into and out of an opening Po formed in the pull tab P of the slider S.
  • lever 15 is further provided with a shoulder portion 17 having an inclined surface 17' disposed in abutting relation to the lower end of the pull tab P.
  • the lever 15 is pivotally supported on a pin 18 extending between and secured to side walls 19, 20 of the frame member 11.
  • the lever 15 is provided with a cross-sectionally rhombic neck portion 21 having a ridge 22 defining on opposite sides thereof symmetric cam faces 23, 24.
  • the ball members 26 are normally pressed against the respective cam faces 23, 24 of the neck 21 by means of leaf springs 27 secured by screws 28 to the frame 1 1.
  • the slider holder 10 in its in operative position appears as shown in FIG. 2, wherein the pair of ball members 26 are pressed against the first or forward cam faces 23 by the action of the leaf spring 27 so that the lever 15 is urged rearwa'rdly into substantially upright, retracted position, with a tapered tip end 16' of the head 16 disposed clear of the slit 13 and with part of the inclined surface 17' of the shoulder 17 ex tended across the slit 13.
  • the slider S is mounted on the slider rest 12 of the holder 10 with the pull tab P inserted dependently within the slit 13 as shown in FIGS. 2 and 4.
  • the slider body is slightly raised above the slider rest 12, and the pull tab P has its tip end barely in contact with the inclined surface 17 of the shoulder 17 of the lever 15.
  • the slider S is now depressed by finger pressure just hard enough to let the pull tab P toss the shoulder 17 down, thus to move the lever 15 slightly counterclockwise and thrust the tapered end 16' of the head 16 into the opening P0 of the tab P.
  • the rhombic neck 21 advances between and pushes apart the 0pposed balls 26 against tension in the springs 27, and as the balls 26 ride over the ridges 22 of the rhombic head 21, they will roll swiftly downthe rearward cam faces 24 under the influence of inwardly directed tension in the leaf springs 27.
  • the aforesaid finger pressure with which to press the slider S downwardly is required only to an extent suflicient to cause the balls 26 to ride over the ridges 22 of advancing rhombic neck 21, whereupon the balls 26 roll down the rearward cam faces 24 of the rhombic neck 21 under the influence of tension in the springs 27, causing the lever 15 to rotate counter-clockwise as indicated by the the slider S is locked position thereon.
  • the downwardly biased tip 16' of the lever 15 urges .the pull tab P further downwardly until the locking member inthe slider is retracted clear of the fastener element guide channels formed in the slider body, as shown in FIG. 4.
  • the slider S seated on the rest 12 of the holder 10 is held advantageously immovable simply pulled upwardly so that the pull tab P moves the lever 15 clockwise into retracted position, releasing the locking head 16 from the opening P of the tab P.
  • lever 15 may be retained securely in this retracted position by the action of the ball members 26 which have now been brought into contact with and compressed against the forward cam faces 23 underthe influence of return tension of the leaf springs 27.
  • leaf springs 27 may be substituted by a coil spring, and such spring member and ball member may be provided only on one side of the lever 15.
  • EMBODIMENT n Referring to FIGS. 6.thro ugh 8, there is shown a modifiedstructure of the slider holder 10 according to theinvention, wherein the slider holder 10 has, similar to the first embodiment, aslider rest 12 on top of a supporting frame 11. A slit 13 is likewise formed longitudinally through the interior of the supporting frame 11 for thrusting therethrough the pull tab P of the slider when it is placed on the slider rest 12 in the manner already discussed.
  • the supporting frame 11 is provided with a cavity 14 for accommodating therein a springactuated lever member 15 having wedge-shaped upper and lower projections 16 and 17.
  • the lever 15 is pivotally supported on a pin member 18 extending between and secured to the inner side walls 19, 20 of the supporting frame -11
  • a tension spring 29 is employed as a means for resiliently retaining the lever 15 in either a forward or a rearward set position.
  • the tension spring 29 spans between an upper pin 30 adjacent to the upper end of the lever means 15 and a lower-pin 31 extending from the frame member 11 beneath the lower end of the lever '15. It is preferred 'to locate the three pin members 18, 30 and 31 in such geometric relation that the lever 15 assumes its neutral position when these pins are held in vertical alignment with one another.
  • any appreciable forward orrearward biasing movement from the said neutral position may bring the lever 15 into its forward or rearward set position under the influence of tension in the spring 29.
  • the lever 15 is held in its rearward set position with its upper end portion resting against the end wall of the supporting frame 11, as shown in FIG. 7.
  • FIG. 9 shows another modification of the invention wherein the lever 15 is provided at its lower-end with cam surfaces 32 and 33 on opposite sides of a ridge 34. Disposed in abutting relation to the lower end of the lever 15 is a pusher rod member 35 which is urged upwardly by a compression spring 36 accommodated in the bottom wall of the supporting frame member 11.
  • the upper end of the pusher member 35 is normally abutted against the rear cam surface 33 so as to hold the lever 15 in its rearward set position, with the locking projection 16 retracted from the slit l3, and
  • This flexing movement of the I lever 15 causes the pusher member 35, which has "been engaged with the rear cam surface 33, to ride over the ridge 34 and come into engagement with the forward cam surface 32.
  • the sliders may be swiftly set into position for threading through a fastener chain F by the-action of the spring-actuated pusher member 35 sliding down the forward cam surface 32 without the. aid of additional finger pressure.
