UNITED STATES PATENTS 10 Claims, 6 Drawing Figures 2,024,588 12/1935 Lesser ..70/371 X LOCK MEANS FOR RELATIVELY SLIDABLE CLOSURES The invention relates to the novel structure of lock means for sliding doors or windows. Such closure ele ments are conventionally mounted at least in pairs within a jamb on trackways in such a manner that their related edges overlap when in closed position and which may be moved relative to each other into open position.

Most sliding closures comprise at least two panels, each consisting of relatively narrow frame members, generally extruded from relatively soft aluminum, which carry a large pane of glass. One or more of the panels may be stationary, and the movable panel may slide either outside or inside of the stationary panel.

Heretofore, it has been extremely difficult to provide fool-proof means to lock such closures in closed position. Hasp locks, bolts and rigid movable bars extending between a door frame and jamb have conventionally been used to lock such closures, but have been found easy to jimmy by slightly lifting the door relative to the track or by pulling the mounting members from the relatively soft aluminum extrusions, or to interfere with door operation, or to be unsightly, or not adaptable to some makes or styles of doors because of structural variations.

In the present disclosure there is provided a lock element that is removably mounted on one of the pairs of closures in such a manner as to be abutted by the related closure. Key actuated means is carried by the element to secure it mounted.

It is therefore an object of the invention to provide lock means of the character referred to.

Another object of the invention is to provide a novelly constructed lock bar for a slidable closure.

Another object is to provide a lock element with key actuated means to engage in a slidable closure.

Another object is to provide a lock structure of the character referred to which is not expensive or difficult to manufacture, which may be applied to a slidable closure readily, which is adequately versatile to lock all conventional sliding glass doors, and which is very efficient in use.

Other objects and advantages of the invention will become apparent with reference to the following description and accompanying drawings.

In the drawings:

FIG. 1 is a fragmentary inside elevational view of a closure installation, showing the lock element in place.

FIG. 2 is a vertical sectional view taken substantially on line 2 2 of FIG. 1.

FIG. 3 is a horizontal plan view of the lock element, as viewed along line 3 3 of FIG. 2.

FIG. 4 is a detail sectional view of the key-actuated lock, viewed along line 4 4 of FIG. 3.

FIG. 5 is a fragmentary detail sectional view similar to FIG. 2, showing a modified embodiment of the invention including an interconnected bracket for selfstorage of the lock element when in operative position.

FIG. 6 is a fragmentary detail elevational view of the modified embodiment shown in FIG. 5, except the lock element is shown in solid lines when in stored position and in dotted lines as the lock element is moved from operative to stored position.

Referring to the accompanying drawings which show an exemplary embodiment of the invention, the present lock means'is designed primarily for use in association with horizontally disposed sliding doors or windows, 11 and 12. As shown, these closures may each comprise a glass panel 13 surrounded by a metallic frame 14, frequently fabricated from extruded aluminum. The closures are mounted side by side in a jamb or casement frame 15, which includes a sill 15a, having suitably formed

horizontal tracks

16 and 17 along which the closures slide. Either

closure

11 or 12 may be moved relative to the other closure into an open position, and when in their closed positions, their complemental

vertical margins

18 and 19 overlap.

In order to lock the closures against relative sliding movement while they are in their closed positions, there is provided a removable lock element, generally indicated at 21, which is best shown in FIG. 3. This lock element comprises an elongated body 22, preferably of square bar stock, having at one end a flange 23, which is perpendicular to one face thereof. Flange 23 carries on its outside face a stud 24, and a similar but heavier stud 25 projects from the back surface of the body at some distance from the flange 23. Adjacent to the other end of said body is a barrel type key-actuated lock 26.

As best shown in FIG. 4, the lock 26 comprises a sleeve 27 that is secured in an aperture 28 in the body 22, as by means of a set screw 29. A lock barrel 31 is rotatable in sleeve 27, it normally being held against rotation by conventional key-actuated tumblers (not shown). The rear face of sleeve 27 is formed with a non-axially aligned circular projection 32 which is apertured to receive therethrough, for rotation, a stem 33 carried by the lock barrel 31. Mounted firmly on the stem is a locking eccentric 34 which is so arranged that when in non-locking position it aligns with the projec' tion 32.

In use, the lock element is laid against the inside face of the outside closure 11, with its flanged end in substantial abutment with the edge of the inside closure 12. To insure proper positioning and attachment of the lock element, the edge of closure 12 has a hole 35 to receive the stud 24 and the inside face of the outside closure 11 has a pair of holes 36 and 37 to receive, respectively, the stud 25 and the circular projection 32 andlocking eccentric 34, the latter at the time of insertion into the closure hole being in its non-locking position. When a key, inserted in the barrel 31, is rotated one-half revolution, the eccentric 34 is carried into locking position behind the wall 14a of frame 14.

Compensation for variances in the thickness of the wall 14a is afforded by re-adjustment of the position of sleeve 27 upon manipulation of the holding set screw .It will be observed that when the lock element is securely positioned as above described and locked, there is provided a positive abutment lying in the path of each closure member so as to prevent their sliding past one another.

When the lock element is not in use, it may be stored in a bracket 38 attached to the inner closure 12, as shown. If desired (holes not shown), this bracket may comprise a saddle having therein holes of the same size and shape and spaced apart in the same manner as

closure holes

35, 36 and 37, respectively, to accommodate stud 25, circular projection 32 and locking eccentric 34, respectively, so that the lock element may be removably secured in the bracket by a half revolution of the key, thus moving the eccentric into locking position, as described.

Referring to the modified embodiment shown in FIGS. 5 and 6, the lock element 21a is substantially similar to lock device 21, except the rear edge of the flange 23a is chamfered and a hinge pin assembly 39 is provided for connecting the lock element to a modified storage bracket 48. This modified storage bracket includes a saddle 40, an angular strap 41, and a guide 42 and stop member 43.

In use, the modified lock element is unlocked from the closure, slid away from the closure on hinge pin assembly 39 along guide 42 until stop 43 is reached, then pivotally swung upwardly and moved toward the closure and nested in the saddle 40 for storage. To reinstall the lock element on the closure, the storage procedure is reversed.

While I have described preferred embodiments of my invention, the device described and illustrated is not intended to be restrictive, as many changes in the structure can be easily accomplished without departing from the spirit or scope of my invention. Accordingly, I do not desire to be limited to the exact disclosure described.
