3 Claims. (Cl. 29266) ABSTRACT OF THE DISCLOSURE The invention provides a device for urging a slidable pane to a position against a fixed pane and against a window jamb remote from the fixed pane and for locking the slidable pane in that position. The device comprises a base for attachment to a window frame, a striker bar mounted on the base for both pivotal and sliding movement, and a handle connected pivotally to the base and to the striker and actuable to effect movement of the striker relative to the base. The arrangement of the pivotal connections is such that when the window is locked is cannot be opened without manipulating the handle.
This invention relates to a lock for sashless sliding glass windows comprising a frame and at least two overlapping glass panes, at least one of the panes being slidably mounted and having a side edge adapted, in the closed position of the window, to abut a jamb of the frame.
It is an object of the present invention to provide a lock adapted to be mounted on the frame and, when actuated, to urge the overlapping panes together and preferably, at the same time, to urge the sliding pane towards the jamb to effect sealing engagement therebetween.
Accordingly, the lock of the present invention comprises a base adapted for attachment to the frame of a sashless window adjacent a sliding window pane, a striker bar for engaging and looking said pane against sliding movement, a handle, first pivot means pivotally interconnecting said handle and said base, second pivot means pivotally interconnecting said handle and said striker bar to allow pivotal movement therebetween, and third pivot means pivotally interconnecting said striker bar and said base to allow pivoted movement of the striker bar toward and away from the sliding pane, said first, second and third pivot means being mutually spaced whereby manipulation of said handle effects pivotal movement of said striker bar and the arrangement being such that, in the locking position, the striker bar cannot be moved away from the pane by pressure on the pane but only by manipulation of the handle.
A preferred embodiment of the present invention comprises a base plate adapted to be mounted on the frame of a sashless window adjacent to a sliding glass pane, a striker bar mounted on the base plate and means provided to engage the striker bar with the sliding glass pane whereby the sliding glass pane may be urged against the fixed pane and sealingly engaged with a jamb of the frame in closed position, the said means including a pin and slot connecting said base plate and said striker bar to permit both pivotal movement of the striker bar towards and away from the slidable pane and slidable movement of the striker bar substantially parallel to the slidable pane, an operating handle, first pivot means mounting said handle on said base plate and second pivot means connecting said handle and said striker bar and laterally spaced from said first pivot means, whereby, upon pivotal movement of said handle toward the slidable pane, said striker bar engages said sliding pane and urges said pane both outwardly and laterally.
The invention, both as to its structure and mode of operation, will be better understood by reference to the following disclosure and the accompanying drawings of a preferred embodiment. In the drawings:
FIGURE 1 is a fragmentary prespective view of the lock of the present invention shown in locked position in engagement with a sliding glass pane;
FIGURE 2 is a plan view of the lock of the present invention showing the striker bar in initial contact with the sliding glass pane; and
FIGURE 3 is a plan view of the lock of the present invention showing the striker bar in full engagement with the sliding glass pane, the pane being sealingly engaged with the jamb of the window frame.
Referring in detail to the drawing, specifically to FIG URE 1, the lock 1 is shown in locked engagement with a glass pane 3 which is slidably mounted in groove 4 of a sashless window frame. The groove is formed longitudinally in sill 2 of the frame and, as shown in FIG- URES 2 and 3, groove 4 extends laterally into a jamb 5 at 9.
As illustrated, lock 1 is comprised of a base plate 6, a striker bar 11 and a handle 16. Plate 6 has a guide pin 12 rigidly mounted thereon. The striker bar 11 has a main straight portion with a curved end designed to contact pane 3 and also has a guide slot 13 adapted to fit over pin 12 of base plate 6. Handle 16 is pivotally connected to bridge member 17 of plate 6 by means of upwardly directed pivot pin 18 disposed thereon and engaging in a corresponding hole in the bridge member. Handle 16 further includes a downwardly directed pin 14, eccentrically positioned with respect to pivot pin 18 and adapted to fit snugly into a corresponding circular hole in striker bar 11 to pivotally connect the handle with the striker bar. Striker bar 11 is further provided with a resilient pad or member 20 having a friction surface 21 and positioned on the curved end adjacent pane 3.
The base plate 6 is constructed with laterally extending flanges 10a and 10b, the flanges being provided with slots 8a and 8b for receiving screws 7, whereby the lock may be slidably adjusted on sill 2 relative to glass pane 3.
The lock 1 is shown in the open position by means of the dotted lines in FIGURE 3. It will be noted that, in this open position, pin 14 is located on the opposite side of pivot pin 18 from pane 3 and that striker bar 11 is displaced towards the left, away from jamb 5. It will also be noted that with the lock in open position, slot 13 is angulated with respect to the planar surface of pane 3.
To lock the sliding pane 3 in sealing engagement with the fixed pane 22 and jamb 5 of the frame, the pane 3 is initially pushed by hand laterally to the right until it enters groove 9, as shown in FIGURE 2. Handle 16 is then swung in clockwise direction from the dotted position shown in FIGURE 3 so that pin 14 swings the striker bar 11 about pin 12, driving the bar towards pane 3. Resilient pad 20 contacts pane 3 and urges the pane outwardly across groove 4, bringing pane 3 into flush contact with the opposite side of groove 4 and the fixed pane 22 as illustrated in FIGURE 1. At this point slot 13 is parallel to the planar surface of pane 3. Pin 14 is positioned to the left of pivot 18.
Upon further rotation of handle 16 in the clockwise direction, pin 14, as well as further urging bar 11 against pane 3, pushes striker bar 11 laterally to the right, thereby urging pane 3 against jamb '5, so that upon full rotation of handle 16 to the position shown in solid lines in FIGURE 3, pane :3 is sealingly engaged with jamb 5 as illustrated.
What I claim as my invention is:
1. A lock for sliding glass windows having a frame and at least two overlapping window panes, at least one of said panes being slidably mounted, said lock comprising a base plate adapted to be mounted on said frame adjacent the slidably mounted pane, a striker bar mounted on said base plate and means provided to engage said striker bar with said slidably mounted pane whereby said pane may be urged against a fixed. pane and sealingly engaged with a jamb of said frame in a closed position, said means including a pin and slot connecting said base plate and said striker bar to permit both pivotal movement of the striker bar towards and away from the slidably mounted pane and slidable movement of the striker bar substantially parallel to the slidably mounted pane, an operating handle, first pivot means pivotally interconnecting said handle and said' base plate and second pivot means connecting said handle and said striker bar and laterally spaced from said first pivot means, whereby, upon pivotal movement of said handle toward the slidably mounted pane, said striker bar engages said slidably mounted pane and urges said pane both outwardly and laterally, said second pivot means, when said lock is. in an unlocked position, being located on the opposite side of said first pivot means from said slidably mounted pane and, when said lock is in a locked position, being located intermediate said first pivot means and said slidably mounted pane with said slot extending substantially parallel to the slidably mounted pane.
2. A lock as claimed in claim 1 wherein the pin is mounted on said base plate and the slot is disposed longitudinally in said striker bar and said second pivot means comprises a pin mounted on said handle eccentric to said first pivot means and" engaging in a circular hole provided in said striker bar.
3. A lockas claimed in claim 1 wherein said striker bar is provided with a friction surface.
