Definitions
- the present invention relates to a lock, more precisely to a door lock with hook- shaped latches showing improved security characteristics.
- Locks offering high security characteristics that is to say, locks with hook-shaped dual latches engaging in suitable slots within the door frame are well-known in the circles of security lock manufacturers. Those are especially advantageous in that when fully locked, they simply provide multiple axes locking so as to withstand both vertical and horizontal forces produced in association with and during burglary attempts.
- the disclosure herein differs from the available prior art in that it features a special arrangement designed to prevent burglary attempts specifically aiming at rendering hook-shaped latches non-functional by damaging their rotation mechanisms. Although locks with those types of latches are substantially advantageous over a regular linear latch lock, they still incorporate certain vulnerabilities.
- the lock case side walls and several individual components of lock hardware are typically secured to each other within the case in several points.
- the pins on the rotation axes of the hook latches are also secured to the sheet material side wall. This becomes a serious drawback especially in the event of a burglary attempt as exemplified earlier.
- the linear tension produced by the perpetual screw along the transversal axis of the door in the direction of the door frame especially requires the hook latches to resist against the outward force induced on the hook ends.
- Break of the hook-shaped latches can be prevented and remedied by way of appropriate material selection.
- the break away force will then exert on the axles and on the guided hook latch actuation pins.
- the hook latches Upon breaking off of the pivoting pins, whose primary function is not retaining the integrity of the system and resisting against outside forces but to constitute the rotation center thereof, the hook latches will first loose contact with the case side sheet and by a certain damage on the guided actuation pins, the latches will practically be free and not anymore secured to the lock case.
- the present invention solves the specific problem identified above by making use of the lock panel, which is already made of a strong material and which is suitable for resisting against forces that are to cause movement of the latches outside their predetermined outermost limit positions.
- Primary object of the present invention is to provide a high security door lock with hook-shaped latches the outward movement of which is kept within a predetermined range and can not be removed from the lock case.
- the present invention proposes a security lock comprising a regular sliding bolt along with a set of separate hook-shaped latches in the form of curvilinear projections operating jointly in the manner to interlock with suitable latch slots on the door frame.
- said curvilinear latches are additionally provided with a plurality of pins vertically projecting from the lateral surface thereof in the manner to face either of the case side sheets.
- Fig. 1a demonstrates a transversal perspective side view of the lock case according to the present invention.
- Fig. 1 b demonstrates the door frame side lock panel according to the present invention.
- Fig. 2 demonstrates a longitudinal perspective side view of the lock case according to the present invention. -A-
- Fig. 3 demonstrates another transversal perspective side view of the lock case according to the present invention.
- Fig. 4 demonstrates the hook-shaped latches according to the present invention.
- Fig. 5 demonstrates the lock case side sheet according to the present invention.
- the lock assembly in Fig. 1 a comprises a plurality of latches (12, 13 and 14) movable relative to said assembly (1 1 ) in the manner to engage in suitable slots (15, 16) on the lock panel (18), an actuator mechanism for switching said plurality of latches between a locking and an unlocking positions and last but not least a transmission mechanism transferring motion to said plurality of latches (13, 14).
- a set of separate hook-shaped latches (13, 14) in the form of curvilinear projections operating reciprocally in an integral manner are employed so as to interlock with a suitable latch slot (19) laid on the frame side lock panel (20).
- Said curvilinear latches (13, 14) are designed to be operated jointly and to be rotating by way of axles (21 ) connected thereto.
- the hook-shaped latches (13, 14) are conventionally designed to have a curvilinear side on the outer portion of the head part, the latter extending inward in the form of a right-angled corner and forming therein a space between two blocks. One of those blocks is actually the head portion, which engages into the slot (19) on the lock panel (20).
- the linearly sliding bolt (12) is conventionally controlled by a handle hub in the form of a spring loaded structure actuated by the handle rotating a mechanism transferring motion to the spring loaded structure.
- the actuator mechanism of the linear bolt (12) and the transmission mechanism thereof, are widely practiced in the art and need not be further mentioned herein.
- the behavior of the bolt (12) with regard to the handle hub is apparent to the person skilled in the art.
- curvilinear latches (13, 14) rotation of the axles (21 ) so as to effect movement of the same is realized by an actuation mechanism started by insertion of a key into the keyhole (22) in the manner to advance a rotatable element (not shown), the latter commanding an arm suitable for engaging in a groove (22) to advance said actuation mechanism for curvilinear latches (13, 14).
- the function of a lock cylinder is apparent to the person in the art.
- the actuator means for the latches (13, 14) is typically comprised of a linearly guided unidirectionally sliding plate (25) with two gripping arms (29) extending to the latches' (13, 14) rotation center (21 ).
- the curvilinear lock bolts (13, 14) are designed to provide a single-turn 90-degree displacement ensuring engagement position into the panel slot (19) in one turn.
- Turning of an appropriate key in the keyhole (22) causes the axles (21 ) and a couple of redirection pins (23) that are guided within the latches (13, 14), to rotate said latches (13, 14) accordingly.
- Each of said pins (23) is driven back and forth between two edges of a guiding channel (24, Fig. 2), depending on the engaging and disengaging positions of said latches (13, 14). Synchronous movement of said redirection pin (23) together with said axle (21 ) leads to a full step 90-degree slip of the curvilinear latches (13, 14) in a reciprocal manner.
- each gripping arm (29) extending to each latch (13, 14) comprises an open end recess in order for laterally receiving said axles (21 ), whose bottom surfaces are secured to a suitable slot on at least one of the lock case sidewalls (28).
- the axles (21 ) are fully encircled with the exception of the recess's open end, which is preferable to limit movement thereof.
- each gripping arm (29) reciprocally advances to slip said redirection pins (23) to the channel (24) limits and further advancing of the gripping arms (29) causes the redirection pins (23) to carry said latches (13.14) around each rotation centers (21 ) to the full-locked position.
- the present invention features a set of special arrangements to keep the redirection pins (23) and the axles (21 ) away from the induced force components.
- said curvilinear latches (13, 14) are additionally provided with a plurality of pins (26) vertically projecting from the lateral surfaces of their body portions that remain within the lock case in locked position.
- the reinforcement pins (26) are the first barriers to contact the lock panel (20) in any attempt to slip said latches outwardly, that is, in the direction of the door frame. Since they are longitudinally embedded in the latch (13, 14) body in a secure manner with the head portions slightly running over the latch (13, 14) surfaces in a manner to form a sufficient contact surface with the lock panel (20) portion outside the latching slot (19), letting the latter stop the entire latch (13, 14) body moving and resisting against outward forces otherwise exerted on the redirection pins (23) and the axles (21 ).
- the reinforcement pins (26) are located substantially close to the lock panel (20) considering the locked position layout of the latches (13, 14). In other words, the distance of the reinforcement pins (26) to the lock panel (20) is smaller than the radius of the reinforcement pin (26) itself. More precisely, the smallest distance between a point of the reinforcement pins (26) and the lock panel (20) is smaller than the radius of the reinforcement pin (26) itself.
- reinforcement pins may also be installed on the far end of the latch (13, 14) to the lock panel (20).
- Such a pin (27) is shown in Fig. 4.
- Such pins (27) projecting symmetrically from both surfaces of a curvilinear latch (13, 14) will further delay removal of latch (13, 14).
- the present invention proposes a locking assembly (1 1 ) comprising a plurality of regular and curvilinear latches (12, 13 and 14) movable relative to said assembly (11 ) in the manner to engage in suitable slots (15, 16) on the lock panel (18), actuator mechanisms for actuating said regular and curvilinear latches (12, 13 and 14) and transmission mechanisms transferring motion to said plurality of latches (13, 14), said curvilinear latches (13, 14) being provided with at least one reinforcement pin (26) projecting from the lateral surfaces of the latch (13, 14) body portions that remain within the lock case in locked position.
