REVERSIBLE AUTOMATIC LOCK SLIDER Filed Aug. 5, 1960 3 Sheets-Sheet 3 United States Patent 3,03%,227 REVERSIBLE AUTGMATKC LGCK SLIDER Milton L. Godfrey and .Iarnes L. Vodeniehar, Meadville,
Pa., assignors to Talon, Ina, a corporation of Pennsylvania Filed Aug. 5, 1%0, Ser. No. 47,860 13 (Iiairns. (Cl. 24-40514) This invention relates to slide fasteners and, particularly, to an improved reversible or double-acting automatic lock slider therefor.
In most lock sliders, the pull or means for operating the lock and for manipulating the slider are disposed on one side thereof and, consequently, accessible from that side of the slider only, which makes such sliders limited in their application. It has been proposed heretofore, to provide a lock-actuating means or pull on each side of the slider so that the slider and locking means may be operated from either side of the fastener so as to provide a reversible or double-acting lock slider.
While various types of reversible or double-acting autom'atic lock sliders, i.e., a slider having a pull or actuating means arranged on either side of the slider so that the fastener can be operated from both sides, have been heretofore suggested and used, they have been in most cases neither satisfactory nor practical. In some oases, such sliders were bulky and fragile, and consisted of a multiplicity of parts which were relatively difficult to fabricate and assemble. In other cases, while such sliders would operate satisfactorily from one side of the slider, the locking means would stick or bind and not operate properly when manipulated by means from the opposite side thereof.
According to the present invention, there is provided a reversible or double-acting automatic lock slider which is strong, rugged and compact in its construction, with the parts thereof being so constructed and arranged that they can be conveniently fabricated and assembled.
It is one of the objects of the present invention to provide an improved lock slider for slide fasteners which can be easily manipulated and unlocked manually from either side thereof so as to provide a reversible or double-acting look slider.
It is another object of the invention to provide an improved automatic lock slider of the reversible or doubleacting type which consists of a minimum number of relatively inexpensive parts which can be easily and quickly assembled.
It is a further object of this invention to provide an improved reversible or double-acting lock slider which is v more positive in its action than other such sliders heretofore suggested and used, whereby the locking means can be effectively unlocked from either side of the slider and, at the same time, will be effectively locked automatically at any point along the fastener.
Various other objects and advantages of this invention will be more apparent in the course of the following specification and will be particularly pointed out in the appended claims.
In the accompanying drawings, there is shown for the purpose of illustration, an embodiment which our invention may assume in practice.
In these drawings:
FIG. 1 is a fragmentary plan view of a slide fastener with which the improved slider of the present invention is incorporated,
FIG. 2 is a plan view of one side of the slider body,
FIG. 3 is a plan view of the opposite side thereof,
FIG. 4 is an end view of the same,
FIG. 5 is a side elevational view of the completely assembled slider in accordance with the present invention, showing the locking member in its locked position,

FIG. 7 is a sectional view taken on line 7-7 of FIG. 6,
FIG. 8 is a side elevational view of the improved slider of the present invention, similar to FIG. 5, showing the locking member in its unlocked position,
FIG. 9 is a top end view of our improved slider,
FIG. 10 is a sectional view taken on line 10-10 of FIG. 8, and
FIG. 11 is a perspective view of the locking member.
Referring more particularly to the drawings, there is shown in FIG. 1, a conventional type slide fastener comprising a series of spaced-apart interlocking fastener elements 2 attached to the opposed beaded edges of a pair of stringer tapes 3. There is mounted on the fastener elements 2, the slider, generally designated at 4, of the present invention for longitudinal movement therealong for engaging and disengaging the fastener elements in a manner well known to those skilled in the art. This slider consists generally of a body member having spaced-apart upper and lower wings 5 and 6, respectively, connected at one end thereof by a neck portion 7 so as to provide substantially a Y-shaped channel 8 within the slider body.
According to the present invention, there is arranged in the outer side of the upper wing 5 centrally thereof, as more clearly shown in FIGS. 2 and 4, a longitudinally extending lug-like portion 9 having a transversely extending opening 10 therein which communicates preferably with an angularly arranged slot 12' in the upper wall of the lugs.
There is provided a cap-like locking member 13 having side walls 14 and an upper end wall 15. Each of the side walls 14 is cut out at the lower edge thereof, as at 16, so as to provide a cam-like lower edge 17 for a purpose hereinafter to be described. On one of the side walls 14, adjacent the lower end thereof, there is arranged a locking prong 18-.
This locking member 13 is disposed over and around the lug-like portion & of the slider body and the side walls 14 are indented, as at 19, so as to provide inwardly extending projecting portions which are disposed in recesses or indentations 24} in either side of the lug-like portion whereby the locking member is pivotally attached thereto. In such position the locking prong 18 extends into and through a rectangular-shaped aperture 18a in the slider wing 5 and into the slider channel 8, as shown more clearly in FIGS. 5, 6, and 7 of the drawings. There is arranged in under the locking member 13* and between the same and the upper surface of the wing 5 on the upper side of the lug-like portion 9, preferably a coil spring 21 for biasing the locking member toward its locked position. There is provided a pull or manipulating member 22 having a transversely extending trunnion portion 23 which is disposed in and extends through the opening 10 in the lug-like portion 9 and is disposed in the recesses 16 in the side walls 14 of the locking'member.
As more clearly shown in FIGS. 3 and 4 of the drawings, on the opposite side of the slider body centrally thereof, there is provided a longitudinally extending luglike portion 24, similar to the lug-like portion 9, which also has a transversely extending opening 25 therein which communicates preferably with an angularly arranged slot 26 in the upper wall thereof and so as to a provide an'upper wall 30 There is provided a cap-like member 27 having side Walls 28 and an upper end wall 29. Each of the side walls is cut out at the lower edge thereof, as more clearly shown in FIGS. 5 and 6 so as to provide lower cam edges 31. This cap-like member 27 is disposed over and around the lug-like portion 24 and the side walls '28 are indented, as at 33, so as to provide inwardly extending projecting portions which are disposed in recesses or indentations 34 in either side of the lug-like portion 24 whereby this cap-like member likewise is pivotally attached thereto. The lower end of each of the side walls 28 preferably have hook-like projections 35 having cam surfaces 32 on the upper edge thereof which projections extend into slots 36 in the wing 6 to either side of the luglike portion 24, as more clearly shown in FIGS. 5, 6, and 7 of the drawings for the purpose of positioning and guiding the cap-like member 27 in its movement.
There is provided another pull or manipulating member 37 having a transversely extending trunnion portion 38 which is disposed in and extends through the opening 25 in the lug-like portion 24 and is disposed in the recesses 30 in the side walls of the cap-like member 27.
As more clearly shown in FIGS. 5, 6, 8, and 9, there is arranged in a vertically extending slot 50 in the upper end of the slider body adjacent the neck portion 7 thereof, a relatively thin link-like or interconnecting member 40 having transversely extending opposed arm- like portions 41 and 42 arranged at each end thereof, so as to provide substantially a T-shaped end portion at each end.
The arm-like or substantially T-shaped portion 41 on one end of this member 40 is disposed under the end of the locking member 13 directly next to the end wall 15 thereof with the arm-like portions 41 pivotally positioned in recesses 43 in the opposed side walls 14 of the locking member. The arm-like or substantially T-shaped portion 42 on the other end of this link-like member 40 is disposed under the end of the cap-like member 27 on the opposite side of the slider body directly next to the end wall 29 thereof with the arm-like portions 42 pivotally disposed in recesses 44 in the opposed side walls 28 of this cap-like member. It will be seen that it is the purpose of this link-like member 40 to interconnect the locking member 13 with the cap-like member 27 so that they will be actuated one by the other in a manner and for a purpose hereinafter to be described.
Having described the construction of the improved automatic lock slider of the present invention, it functions in the following manner.
It will be understood that the locking member 13 and the cap-like member 27 assume normally the positions shown in FIGS. and 6 of the drawings with the locking prong 18 positioned between any two of thefastener elements 2 disposed in the slider channel 8 so as to prevent unintentional movement of the slider along the fastener in a manner well known to those skilled in the art.
When it is desired to open or close the fastener either one of the pull members 22 or 37 are grasped to actuate and move the slider along the fastener elements. That is to say, the slider may be actuated to engage and disengage the fastener elements from either side of the fastener. If the pull member 22 is grasped, which is ordinarily on the outer side of the fastener, the trunnion portion 23 thereof contacts the cam-like edge 17 of the locking member 13, as shown in FIG. 8, thereby moving this locking member about its pivotal connection 19 so that the locking prong 18 carried thereby moves to its retracted portion and out of engagement with the fastener elements in the slider channel. It will be seen that this movement of the locking member 13 is against the action of the coil spring 21 thereby loading the same.
If it is desired to operate the slider from the other or inside of the slider to open the fastener, the pull member 37 is grasped and the trunnion portion 38 thereof contacts the cam edges 32 and the inner wall 30 of the opening in the lug 24, thereby moving the cap-like member 27 about its pivotal connection 33 with the lug 24 as clearly shown in FIG. 8. That is to say, the trunnion portion 38 of the pull member 37 in cooperation with the upper wall 30 of the opening 25 in the lug 24 and the cam surfaces 32 moves the locking member 27 about its pivotal connection at 33 by a wedging action. It will be seen that in such movement of the cap-like member 27 the locking member 13 will also be moved about its pivotal connection 19, due to the action of the interconnecting link-like member 40, thereby moving the locking prong 18 from between the fastener elements in the slider channel and permitting the slider to be moved along the fastener elements. It will be understood that when the pull 37 is grasped to move the slider toward its closed position the locking member 13 together with the locking prong 18 carried thereby automatically moves out of engagement with the fastener elements and thereover by a ratcheting action. When both of the pull members 22 and 37 are released it will be understood that the locking member 13 and the cap-like member 27 will again assume the positions shown in FIGS. 5 and 6.
As a result of our invention it will be seen that there is provided a so-called reversible automatic slider i.c., one that can be actuated from either side of the fastener, consisting of a minimum number of parts which can be easily fabricated and assembled.
While we have shown and described an embodiment which our invention may assume in practice, it will be understood that this embodiment is merely for the purpose of illustration and description, and that other forms may be devised within the scope of our invention as defined in the appended claims.
