Fig. 1 is a perspective view of a llock slider made according to'my invention;
Fig. 2 is a longitudinal sectional view through the slider shown in Fig. 1 and illustrating its locking action. l
The invention relates to lock sliders for separable fasteners of the type commonly referred to as zippers, and with such fasteners employing a lock slider it has been common to place the locking element near or at the pivot end of the v pull used to operate the slider or to engage the links of the fastener by some kind of. a lock element disposed within the boundaries of the slider. According to my invention, however, I utilize the end of the pull as a locking member, as will be explained more fully.
In the accompanying drawing, represents a channeled slider body having spaced top and bottom walls 6 and l, joined at the wide end of the slider by a connecting web 8 forming the usual diverging channels at the wide or upper end of the slider, which merge into a single channel at its narrow or lower end. The top and bottom walls l and I have inturned ilanges 9 at their side edges which engage the links I0 of the fastener stringers in coupling said strlngers together 'in the usual manner. AThe coupled or engaged links are illustrated at the contracted end portion of the slider as seen in Fig. 2 of the drawlng. Extending centrally and longitudinally of the top wall and on its upper surface is an elongated lug Il on which is slidably and plvotally supported a nger piece .or pull I2. The lug II has anelongated slot I3 therein which extends from an end wall Il thereof to'the narrow or lowerend of the slider, at which end the slot is open. as plainly shown in the drawing. The lug II has a chamber I Ia therein, in the side walls of whichy are formed elongated apertures I5, the edges of which form elongated bearings which extend lengthwise of the slider and slidably and pivotallv engage the pivot I6 of the.
pull. In 'the Villustrated embodiment, this `pivot may be in the form of a crosshead at the end ofthe pull. The pull which is preferably made of resilient material such as metal is bent intermediate its ends. as shown at Il and thus provided with an arm I2 and an arm or wedge portion I2a, and
the free end of the pull is provided with a loclr-K V ing member, here shown as' a ball I8. the parts be- 'ing so arranged that this ball I8 is adapted to extend beyond the lower end of the slider and approximately into alignment with the channel at that end.
The function of ythe device is to lock the slide against movement in one direction (to the left as shown in Fig. 2) in the following manner:
The ball I8 and the body of the slide are grasped between the :fingers and the portion I2a of the shank of the pull is forced or jammed in the chamber IIa between the wall or stop I4 and the top wall 6 of the slide. This forces and holds the -ball I8 against the links I0 and, in turn, jams the links I0 against the edge I9 of the lower wall 1 of theslide and out of their normal alignment with the channel between the top and bottorn walls B and l. Downward movement of the slide (movement to the left as shown in Fig. 2) is then prevented by engagement of the edge IS with the links I8. f.
To release the slide from the locked position, the pull is moved out of the jammed position shown in Fig. 2 by moving it to the left o1.I the position shown in full lines in Fig. 2. fI'he sfide can 'then be freely moved along the links. In
moving the slide to the left of the position shown in Fig. 2, the ball is normally held by the fingers with the cross head I6 engaging the end I5a of the slot I5. In moving the slide to the right of the position shown in Fig. 2 the pull may convenlently occupy the position shown in dot and dashlinesinFig. 2. i Normally the pull is moved to therisht (which may be an upward movement) as far as it will gov and in contact with a conventional stop. It is then locked in position in the manner set .forth and movement in the opposite direction is pre- 40 vented. l Preferably, the pull lis arranged as shown and described in a manner such that the locking vmem-- ber will 'operate in alignment with the single channel at the lower or narrow end'of the slider. but, if desired for any reason, the invention could be adapted to have the locking member operate in either one of the other channels. Ordinarily, however, the arrangement shown is preferable While I have shown the invention as embodied in a specific form, rais to be understood that various changes in details may be made `without'. departing from the scope of the invention as defined by the appended claims.
I claim:
'1. A slider for separable fasteners of the class described# comprisingqabody having diverg channels at its upper end merging into. single channel at its lower end, a pull having a pivot at one end thereof, elongated bearings extending lengthwise 'of the slider and slidably and pivotal-f ly engaging said pivot, a locking member on the other end of said pull and adapted to extend beyond said lower end of the slider into locking position in line with saidv single channel, and a. stop on the slider and a cam on the pull arranged to engage each other to cam said pull downwardly to bring said locking member into said locking position.
2.

3. A slider for separable fasteners of the class described, comprising a body having diverging channels at its upper end merging into a single channel at its lower end, a pull having a pivot at one end thereof,velongated bearings extending lengthwise of the slider. and slidably and pivotally engaging said pivot,` a locking member on the other end of said pull and adapted to extend be- `yond one end of the slider into locking position in line with one of said channels, and a stop on the slider and a cam on-the pull arranged to engage each other to cam said pull downwardly to bring said locking member into said locking position,
' said pull being freely movable on said bearings to operate the slider.
4. The combination with a slider for separable fastener stringers adapted to couple and uncouple the links of the stringers, o f a pull having a free end, means pivotally Iand slidably mounting the pull on the slider, the free end of the pull having a ball thereonpositioned beyond the boundaries of the slider, and means for moving the ball into engagement with coupled links of the strlngers rbeyondonenctfofthe vsiii-ler tle'clropening. Y
movement of the slider on saidstringers.
5.
