UNITED STATES PATENT OFFICE.-
RALPH BINNS, OF PITTSBURGH, PENNSYLVANIA, AND WILLIAM A. DE HART, IF TEANECK, NEW JERSEY, ASSIGNORS TO EDWARD H. BINNS AND RALPH H. BINNS, BOTH 0F PITTSBURGH, PENNSYLVANIA.
FLEXIBLE CLOSURE.
Application filed February 28, 1925. Serial No. 12,449.
The present invention relates to improvements in pull members and locking devices for cam sliders of the type employed w1th flexible strips or stringers of spaced interlocking fastening devices. The present invention may be considered as an improvement upon the device covered by the application of Ralph H. Binns, filed February 18th, 1925, Serial No. 10,074.
The pull memberof the present application utllizes the leverage control of the operating slider set forth in said .Binns application, but extends the application of th1s principle to a more effective angular control of the slider in both its locking and unlocking movements. This is accomplished by mounting the pull pin approxi` `mately centrally of the slider body and arranging a reversible pull member kin the 20 form of a blade of spring metal capable of movement from a central position beneath -said pull pin to extend either above or below the slider body. The opposite ends of the pull member are so designed that 25 a slight-outward stress upon the outwardly presented end of the pull member in addition to the pull in the desired direction will bring into action a fulcrumheel for controlling the angular position of the slider upon the interlocking fastening devices. This improved flexible closure mai also include a modification of the slider loc in the form of a frictional drag or brake under the control of manually o erated means such as the lpull member. n improved form of stop upon the stringers is alsoprovided for limiting the locking movement of the slider upon the fastening dev1ces.
In order that the invention may be full understood it will first be described wit reference to the accompanying drawings and afterwards more particularly pointed out in the annexed claims.
In said drawings:
Fig. 1 is a front elevation of a portion of `a flexible closure embodyingthe present invention;
Fig. 2 is a side elevation of the same;
Fig. 3 is a similar view, partly in section, showin the pull member extended below the sli er;
Fig. 4 is a similar view showing the pull member extended above the slider;
Fig. 5 is a rear view of the slider;
Fig. 6 is a transverse sectional view taken on the line 6-6 of Fig. l;
Fig. 7 is a view similar to Fig. 6 showing the locking drag or brake raised away from the locking devices; and
Fig. 8 is a detail perspective view of the slider limiting stop.
In the type of flexible closure to which the present invention relates, two flexible strips or stringers 1, 2 are formed at their inner edges with beads or thickened portions 3 upon which are securedinterlocking fastening devices.
Each interlocking fastening device is preferably formed with a U-shaped yoke 10 embracing and compressed upon the beaded or thickened edge 3 of a flexible Stringer, a narrow ncck 12, a forked hook 13, and the opposite riding lugs or shoulders The specific form and operation of the fastening devices of the preferred construction will be more fully understood by reference to the applicationl of Binns, Binns and De Hart, filed July 5th, 1924, Serial No. 724,355.
The operating cam slider is preferably constructed, as set forth in the above named a plication, of a back-plate and a forep ate 21 mounted in spaced relation upon a inder post (not shown), to provide a fastener receiving channel. The inner faces of the back-plate and fore-plate are provided with controlling grooves 25 separated by a central guide rib or surface 26. The riding lugs 15 of the fasteningl devices operate in the controlling grooves 25.
The fore-plate 21 of the slider body is K provided approximately midway between its upper and lower ends with the outwardly presented ears or lugs carrying a transverse pivot and pull pin 35.
At the upper end of at least one series of interlocking members, is provided a stop lug A27 formed on the yoke 28and having its two arms integrally connected with the arms of a yoke 10a through the web portions 29. The yoke 10a is part of a specially formed fastening member having a narrow neck 12, a forked hook 13a and the riding lugs or shoulders 15a. The connections 29 between the yokes 28 and 10a (which are clamped upon the beaded edge of a Stringer) mutually and effectively brace th'e top fastening member and stop lug to lessen the liability of misplacement from rstrains.
It will be understood that in the closing operation of the slider upon the fastening devices, one of the ears 30 will come into engagement with stop lug 27 and limit the movement of the slider. The stop lug 27 is so mounted that it will pass outside of and along one edge of the slider in this closing movement.
The U-shaped drag or brake member is freely pivoted upon the pin 35 and shaped to fit over the lower end of slider fore-plate 21. The portions of the drafr or brake 40, which are presented toward5 the exposed faces of the interlocking fastening devices, are suitably shaped to frictionally engage the fastening devices for securing the slider in the desired position thereon. As shown this member 4() is formed with a central braking surface 41 designed to engage the edges of adjacent int'erlocked fastening devices, and side braking surfaces 41a to engage the locking devices adjacent riding lugs or shoulders 15.
is a blade-like pull member movably mounted upon the slider beneath the pivot and pull pin 35. This pull member 50 is made of spring metal and is formed with a slight arch or bow shape to cause it to effectively though yieldingly engage the pin 35. Pull member 50 has a central transverse bend or recess 51 which snugly engages pin 35 in its central locked posit-ion as shown in Figs. 1 and 2. The' opposite ends of pull member 50 l are slightly rolled or coiled to form finger pieces 52 and 53, which also act as fulcrum heels for engaging the face of top plate 21 and giving a leverage control of the angularl position of the slider when it is moved upon the fastening devices.
'Ihe devices are shown in normal locked position in Figs. 1, 2 and 6 of the drawings, 1n which position the pull member 50 is sprung beneath the pin 35 with its upper end frictionally engaging the upper central portion of the fore-plate of the slider and its lower end resting upon the drag or brake 40 and holding it in locked engagement with the interlocked fastening devices. In this position stop lug 27 is in engagement with ear 30 of the slider. The slider is held against movement in either direction. To
open the closure the pull member 5() is shift ed into the position shown in Fig. 3 of the drawings to project below the slider and release the drag or brake 40. In this position by slight outward pressure in the direction of arrow w, combined with a downward pull in the direction of arrow y, the filcrum heel 52 will afford suiicient leverage control of the angular position of the slider to prevent digging in at the downward or leading end, and cause the slider to move fieely upon the fastening devices to move them into unlocked position.
lVhen it is desired to fasten the closure, the pull member 50 is moved into the position shown in Fig. 4 in which outward pressure in the direction indicated by arrow combined with the pull in the direction of ari-ow y causes the slider to move freely over the fastening devices to interlock them without any tendency to bind or catch upon them.
