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.
Claims3
A locking mechanism for sliding doors and windows comprising:
- a lock with a lock cylinder having a key hole for the key, including a tab and a cylinder pin integrated in said lock, a toggle box, a track, a stopper, a second chamber, an operating latch, a blocking toggle, an operating handle, left and right side faces, a first chamber, a body portion, a third chamber, a fourth chamber and screws, and a key which includes a key shaft, key head, a bore, an inlet and key teeth, wherein,
- the lock is inserted in the blocking toggle proximate to the left side face of said blocking toggle;
- the operating latch is configured to be displaced together with the blocking toggle;
- the blocking toggle is configured with respect to the toggle box that longitudinal movement of the blocking toggle is effected by the displacement of said operating handle;
- the body portion is attached to the blocking toggle by the screws;
- the third chamber and the fourth chamber in the toggle box are configured to allow movement of said body portion and a body portion adjacent part in the blocking toggle;
- the left and right side faces of the blocking toggle are substantially smooth;
- wherein
- the lock comprises a tab;
- the operating handle of said blocking toggle is configured to be extended outwardly in a straight line in proximate to said right side face of the blocking toggle;
- the tab of the lock is partially housed in a first chamber in the blocking toggle and partially housed in a second chamber in the toggle box;
- the tab is configured to be prevented from displacing in said first chamber;
- the tab is configured to be displaced in said second chamber;
- the first chamber, the second chamber and the track present different heights, widths, lengths and shaping and are superimposed;
- the cylinder pin is configured to be displaced in the track in the toggle box, when said cylinder pin is aligned with said tab in the unblocking position of said locking mechanism;
- and
- the cylinder pin is configured to be abutted against a stopper in the toggle box which is aligned with said track, when the tab is perpendicular with respect to the cylinder pin in the blocking position of said locking mechanism.
