LOCKING MECHANISM FOR SLIDING DOORS AND WINDOWS

Abstract

A locking mechanism for sliding doors and windows includes a lock with a lock cylinder having a key hole for the key. The lock includes a tab and a cylinder pin. The locking mechanism further includes a toggle box, a track, a stopper, a chamber and an operating latch, a blocking toggle, an operating handle and left and right side faces. The key includes a key shaft, key head, a bore, an inlet and key teeth. The abutment of the cylinder pin on the stopper promotes the blocking in the locking mechanism which presents reduced dimensions for application in modern design frame structures.

Claims

2. The locking mechanism for sliding doors and windows according to claim 1, wherein the width of said locking mechanism is approximately 14 mm.

3. The locking mechanism for sliding doors and windows according to claim 1, wherein the diameter of said lock is approximately 6 mm.

DETAILED DESCRIPTION

[0055] It will now be made a detailed description of a preferred embodiment of the locking mechanism 18 for sliding doors and windows according to the present invention.

[0056] The locking mechanism 18 for sliding doors and windows of the present invention has the advantage of allowing the blocking and the unblocking without restrictions nor limitations when inserted into frame structures, in particular structures of sliding windows or doors, it being able to be mounted in very small spaces without implications for the good working and/or performance of said sliding doors or windows, it being simpler and of smaller dimensions, easier to fabricate and having a cost more reduced with respect to existing locking mechanisms for that purpose.

[0057] Such as represented in FIG. 1, the upper portion of the blocking toggle 8, of substantially rectangular shape and left and right smooth side faces 17, 17, includes an operating handle 11 and the lower part of the blocking toggle includes a toggle box 10, an operating latch 9, a second chamber 12 and a track 5. A user fits the key 1 in the key hole 14, such as represented in FIG. 1, and rotates the same into 90 in the counter-clockwise direction. This action causes the displacement of the cylinder pin 7 from the stopper 20 in the track 5 to a position where it is aligned with the tab 19 and enables the movement of the toggle 10.

[0058] Such as represented in FIG. 2, a user can again displace the toggle 10 to the position shown in FIG. 1. Then the user can engage the key 1 in the key hole 14 and rotate the same into 90 in the clockwise direction. This action causes the displacement of the cylinder pin 7 inside the track 5 to a position in which said cylinder pin 7 is arranged into 90 with respect to the tab 19 and abutted on stopper 20, it being thus prevented the movement of the toggle 10.

[0059] Particularly with respect to the cylinder pin and to the track on which it is displaced, they can take on other configurations within the scope of the invention, always in order to enable the blocking and unblocking of locking mechanisms inserted into frames that may enable an efficient working within the mentioned purposes.

[0060] The above described embodiment is illustrative and it is not limitative. Many variations are possible to the locking mechanism for sliding doors and windows shown in the drawings, which are within the scope of this invention such as defined in the claims.
