Definitions
- the present invention relates to a safety lock with front coupling for sliding doors.
- Sliding doors are widely used for aesthetic or dimensional requirements: the door panel slides (within a rail or by resting on low-friction means), passing from a first configuration, in which it clears completely the opening in the wall, to a second configuration, in which it occupies said opening, resting with its front against the jamb.
- locks which have a front hook that is suitable to engage in an appropriately provided selvage located in a corresponding position on the jamb.
- the lock acts as a bolt.
- the aim of the present invention is to obviate the above-mentioned drawbacks and meet the cited requirements, i.e., by providing a safety lock with front coupling for sliding doors that can act both as a latch and as a bolt and prevents the rotation of the hook when said rotation is not imposed by the rotation of the key in the cylinder.
- an object of the present invention is to provide a safety lock that is simple, relatively easy to provide in practice, safe in use, effective in operation, and has a relatively low cost.
- the present front-coupling safety lock for sliding doors of the type that comprises a hook element that is pivoted inside a casing of said lock and is suitable to rotate about said pivot until it protrudes partially from said casing, engaging within a respective selvage mounted on the jamb, characterized in that said hook is constituted by an angular lever that is pivoted to the casing at one of its ends, with a tab that protrudes laterally to the side of said pivoting point to which the end of a frame is pivoted, said frame being suitable to perform an axial translational motion by way of the action of a key-operated cylinder, said frame being associated with a lever provided with an end tooth that is suitable to engage, by way of the action of an elastic means, in respective seats provided on said frame; a rocker being mounted so that it can rotate about its own central portion proximate to said angular lever on the portion that lies opposite the portion provided with the protruding tab, said rocker having an end
- the reference numeral 1 generally designates a safety lock with front coupling for sliding doors.
- a pivot 3 Inside a casing 2 there is, in a substantially central portion, a pivot 3 on which a hook-like angular lever 4 is mounted so that it can rotate.
- the casing 2 has a front opening 5, through which a triangular head 6 of the lever 4 can protrude from the casing 2.
- the angular lever 4 is constituted by a plurality of superimposed laminas, which are mutually joined by means of transverse elements (screws or pins) or by respective welding spots. Proximate to the pivoting point, the lever 4 has a lateral tab 7 on which the upper end of a frame 8 is pivoted.
- the frame 8 is constituted by two elongated lateral laminas 9, which are identical and mutually parallel, face each other, and are joined by means of transverse metallic flaps 10.
- the two laminas 9 have respective facing holes 11, which are designed to accommodate the pivoting element 12; in a lower region, the frame 8 is mounted on a pin 13 that protrudes from the frame 2 by means of slots 14.
- a lever 15 with an end tooth 16 is also rotatably mounted on the pin 13 and is interposed between the laminas 9.
- the frame 8 substantially has, between two successive flaps 10, seats 10a and 10b that are designed to accommodate the end tooth 16 of the lever 15, which is forced into said seats by way of the action of a spring 17, which is also mounted at the pin 13.
- a hole 18 is provided at the front portion of the casing 2, below the opening 5 for the exit of the hook-shaped lever 4, and a pin 19 is accommodated therein so that it can slide longitudinally.
- An axially-acting spring 20b acts on the opposite end 20a of the rocker 20 and keeps the end 20a spaced from the casing 2 and rested in a recess 23 of the lever 4.
- a spring 22 acts on the hook-shaped lever 4, forcing it to exit from the casing 2, and its arm 22a rests on the casing 2.
- the protrusion of the comer 20a from the recess 22 due to the counterclockwise rotation of the rocker 20 can be produced by the full-length retraction of the pin 19 into the casing 2, with consequent resting against the lower portion of the rocker 20, overcoming the action of the spring 20b.
- a key-operated cylinder 24 is inserted transversely at the lower portion of the casing 2.
- the bit of the cylinder 24, during the rotation imparted by the key, interferes with the lever 15, turning it clockwise about the pivot 13 and thus disengaging the tooth 16 from the seat 10a (or 10b) comprised between the flaps 10.
- the cylinder 24 is kept in position by means of a screw 25 that passes through the front surface of the casing 2.
- the lock 1 is mounted in a sliding door so that the pin 19 and the head 6 of the hook-shaped lever 4 protrude frontally with respect to said door.
- Closure of the door by means of the lock 1 is achieved by placing the door 1 adjacent to the jamb and turning the key in the closure direction, forcing a movement that is the opposite of the one described previously, thus making the head 6 protrude and locking it in this position by engaging the tooth 16 in the lower seat 10a of the frame 8.
- the lock 1 can also be left so that the head 6 protrudes from the casing 2 when the door is open.
- the pin 16 lies outside the casing 2 and therefore the end 20a of the rocker 20 is forced by the spring 20b into the recess 23 of the lever 4.
- the lever 4 is therefore locked in this position by the rocker 20, while the tooth 16 rests against the rear face of one of the metallic flaps 10 (the one comprised between the seat 10a and the seat 10b).
- the arrangement of the door adjacent to the jamb entails a retracting rotation of the lever 4, with consequent partial penetration of the head 6 into the casing 2, until the entire head 6 has fully moved beyond the edge of the selvage, entering it fully.
- the pin 19 rests against the jamb, retracting into the casing 2 and releasing the lever 4, which rotates further outward, entailing an upward translational motion of the frame 8 with consequent engagement of the tooth 16 in the seat 10a in the locking position.
- the lock 1 can act both as a simple latch and as a bolt, directly providing separate functions that are currently provided by means of different locks.

Description
Claims (10)
- A front-coupling safety lock for sliding doors, of the type that comprises a hook element (4) that is pivoted inside a casing (2) of said lock (1) and is suitable to rotate about said pivot (3) until it protrudes partially from said casing (2), engaging within a respective selvage mounted on the jamb, characterized in that said hook (4) is constituted by an angular lever (4) that is pivoted to the casing (2) at one of its ends, with a tab (7) that protrudes laterally to the side of said pivoting point to which the end of a frame (8) is pivoted, said frame being suitable to perform an axial translational motion by way of the action of a key-operated cylinder (24), said frame (8) being associated with a lever (15) provided with an end tooth (16) that is suitable to engage, by way of the action of an elastic means (17), in respective seats (10a, 10b) provided on said frame (8); a rocker (20) being mounted so that it can rotate about its own central portion proximate to said angular lever (4) on the portion that lies opposite the portion provided with the protruding tab (7), said rocker (20) having an end (20a) that is suitable to engage in a recess (23) of said angular lever (4) and an opposite end that faces a pin (19) that can slide axially within a hole (18) provided in the casing (2) and normally protrudes therefrom.
