Definitions

  • the present invention relates to a door lock with mechanical locking means, which opens by simply introducing the corresponding key without the need for turning said key and by turning an externally actuated doorknob. Closure of the lock is achieved by simply turning said doorknob without the need to use the key.
  • Opening and closing requires only a half turn (180°) of the doorknob, making the operation of the lock a very quick process.
  • the actuating key incorporates a teethed or crenellated profile on one of its edges, which acts on the locking means of the lock by turning said key.
  • the present invention relates to a lock that allows a quick and easy operation of the lock in such way that it requires only the introduction of the key and the operation of a doorknob to open it, without the need to turn said key in its place.
  • Closing takes place by operating the doorknob without introducing the key.
  • the operation is very quick, due to the fact that the doorknob only needs a half turn (180°) in any direction for opening or for closing.
  • the present invention provides a door lock comprising a frame which is incorporated into the lock housing and which can slide horizontally in the interior of the latter, said frame having one or more latches securely connected to it that can protrude outside of the lock and act as closing elements when they are introduced into the door jamb as the frame is moved to that side, while they are housed in the interior of the lock housing when the frame is moved in the opposite direction, enabling in this way the opening of the door.
  • the frame is linked to two external manually operated doorknobs, one at each side of the door, in such way that a simple 180° turn of one of the doorknobs moves the frame to one side or the other.
  • the invention provides a system of wards which are actuated with the corresponding key, particularly so that it is only necessary to insert the key without having to turn it afterwards to open the door.
  • the wards are laid out in the lock housing transversally in relation to the movement of the frame and can perform small movements in vertical direction.
  • the wards comprise a series of superposed metal plates including a central window for inserting the key and external extensions or collars of different length on each ward, said plates holding respective springs which push the wards through to their location of maximum vertical displacement so as to be positioned in the path of a number of interior protrusions of the frame so that, upon movement of the frame, these protrusions will impact against the ward collars in order to prevent unlocking the lock without prior introduction of the key.
  • the collars of each of the wards are of different length, matching crenellated cut-outs provided on the key profile, so that the introduction of the adequate key causes each of the wards to butt, by means of its respective window, at the corresponding cut-out on the key, limiting the movement of the ward towards the exterior through the corresponding spring, and, in this way, aligning all of the wards' collars in a position that will not interfere with the path of the interior protrusions of the frame and therefore enabling the lock's movement by operating one of the external doorknobs.
  • the present invention provides a lock that enables the opening of the door in a quick and easy way as it only requires to insert the key and to operate the doorknob without the need to turn the key.
  • this invention provides a reduced wear on the key and on the wards by eliminating the need to turn the key for unlocking the lock.
  • the protrusions on the frame are chamfered on one side so that, when closing the lock and sliding the frame, they butt at the ward assembly forcing them to retract, acting against the force exerted by the compression springs, so that the lock can be closed by operating the external doorknob without the need to insert the key.
  • the manually operated doorknobs are mounted at the ends of a shaft mounted transversally on the lock housing and onto which a freewheel is located that is connected from its periphery to a rod which is movably connected to the sliding frame in such way that a simple 180° turn will move the frame in order to open or close the lock.
  • Another objective of the present invention is to provide a system of wards that acts upon the key simultaneously from the top and the bottom sides, thus permitting a greater number of different combinations and therefore of different keys.
  • a wards assembly comprising two types of wards in an alternative arrangement, each ward being inverted in relation to the two neighbouring wards and, in particular, if one group of wards is facing up, the wards in the other group will be facing down.
  • the compression springs are disposed between the ward of one group and the subsequent ward of the other group so that both wards are displaced vertically in opposing directions, each invading the respective paths of the internal protrusions of the frame.
  • the key presents an upper crenellated profile and a lower crenellated profile, in correspondence with the two groups of wards, as one of them will operate by coupling to the key from its upper, while the other will do it from its lower part, thus providing a larger number of different combinations for the lock.
  • a lock in accordance with the invention comprises a rectangular frame (2) that is housed inside the lock housing and is capable of sliding horizontally along the interior of the latter.
  • the frame is produced preferably out of thin plate material and with a width equal to the depth of the lock housing (1) that surrounds the remaining mechanisms such as the driving and blocking system for the wards, as explained later.
  • a number of latches (3) are securely attached to the frame (2) so that they can emerge relative to the door edge acting as closing elements when the frame (2) is horizontally moved to that side, as demonstrated in figures 1 and 2, wherein said latches are introduced into the door jamb.
  • the horizontal movement of said frame (2) is realised by way of a freewheel (20) and a connecting rod (21) provided in its interior, one of its ends tilting around a frame stud (27), while the other end of the connecting rod (21) tilts around a stud provided on the periphery of the freewheel (26).
  • the freewheel (20) comprises two discs (22, 22') securely mounted in parallel on a central point (25) of the freewheel (20), which is traversed by a shaft (23) that protrudes through the lock housing (1) out to the exterior perpendicularly to the longest side faces of the latter.
  • the shaft (23) incorporates on both ends a doorknob (24), as shown in figure 7A, which can be turned manually by an angle of up to 180°, rotating the freewheel (20) and sliding the connecting rod (21) which, at the same time, drives the frame (2) in either direction.
  • the connecting rod (21) is provided with a jog (28) at the point of coincidence with the central point (25) of the freewheel (20) in order to enable the latter to turn in either direction by up to 180°.
  • the frame is provided with a system of wards which are mounted on a ward carrier support (5) which basically comprises two parallel plates (6-6'), as illustrated in the perspective view of figure 5A, which are respectively flush with the two horizontal sides of the frame (2) and one of them being fastened to the bottom of the lock housing (1).
  • a ward carrier support (5) which basically comprises two parallel plates (6-6'), as illustrated in the perspective view of figure 5A, which are respectively flush with the two horizontal sides of the frame (2) and one of them being fastened to the bottom of the lock housing (1).
  • the wards (4) are brackets mounted superposed on top of each other, as described in figure 6, which comprise a central part (12) in which a rectangular window (7) has been provided to accept the key and which is slightly shifted longitudinally in relation to the centre of the ward body with the purpose detailed later.
  • the wards are provided with long neck-like longitudinal extensions defining a head part (8) and a tail part (9) which are fitted between the protruding guides (11-11') provided on the ward carrier (5) to limit the vertical movement of the wards, that is, transversally to the movement of the frame (2), as the central parts of the wards, being wider than the head part (8) and the tail part (9), butt at the protruding guides (11-11') as they move upwards and downwards.
  • the two horizontal sides of the frame (2) are provided with internal protruding stops (13-13') which prevent the horizontal movement of the frame (2) if the corresponding key (10) has not been previously inserted, by each butting at the edge or profile of the neck of the head part (8) or the neck of the tail part (9) of one or more wards (4).
  • the sides of the frame (2) are resting on the two plates (6-6') of the ward carrier (5), one on the top part and the other on the bottom part, acting as supporting guide for the frame.
  • the protruding stops (13-13') on the frame have the same width as the space existing between the two plates (6-6') of the ward carrier (5), preventing the sides of the frame from sliding sideways.
  • the movement of the frame (2) results in the protruding stops (13-13') sweeping over two spaces separated by a distance equal to the length of the wards which, themselves, are all of the same length from head to tail, although their heads and tails are of different lengths between different wards.
  • the assembly of wards comprises two types of wards, depending on their position and the mounting order, wherein each group is inverted in relation to the other group, or, in other words, the wards of one group are turned upside-down in relation to the other group, being the assembly of wards formed by an alternating sequence of wards of one and the other group, as illustrated in figure 7B.
  • the two plates (6-6') forming part of the ward carrier (5) are provided with a groove (14) that will be opposed to the windows (7) of the wards (4) through which the key is inserted from the exterior of the lock, therefore providing a shape and dimensions adequate for the profile of the key.
  • the wards (4) incorporate a lateral extension or arm (19) at the upper end of the body (12) and close to the head (8), while, at the opposed end, close to the tail, they are provided with a leg (17) with a function explained later.
  • the exterior of the ward carrier support (5) is provided with two levers (16-16') mounted over and under the freewheel (20), respectively, comprising at least one elastic element pulling said levers (16-16') towards each other and leaving each of the free ends of the levers (16-16') resting on the respective arms (19) of each group of wards, that is, the free end of the upper lever (16) pushes against the arms (19) of one group of wards, while the lower lever (16') pushes against the arms (19) of the other group of wards, in this way setting the wards in motion until their bodies (12) butt at the protruding guides (11-11'), leaving the tail ends (9) of all the wards in their most exterior position in relation to the ward carrier (5), while the head parts (8) are left retracted.
  • the windows (7) of all the wards (4) coincide, thus permitting the introduction of the corresponding key.
  • the elastic element can be a tension spring (31), mounted so that it connects the ends of the two levers (16-16'), or, alternatively, two independent springs or metal clamps, mounted on the shafts (30-30') of each of the levers (16-16'), respectively.
  • the levers (16-16') are movably joined from one of their ends to respective bolts (30') fastened to the bottom of the lock housing (1), enabling the tilting motion of said levers.
  • Each of the levers (16-16') includes in its central part a wheel (32-32') whose radius matches two circular cut-outs (29-29') provided on the freewheel (20) into which they will be firmly housed in the open and closed positions, while the operation of the doorknobs (24) results in the tilting of the levers (16-16') in opposite directions, separating their free ends, acting against the opposing force of the tension spring (31) in such way that during the rotation of the doorknobs (24) from 0° to 180° the wheels turn over the exterior surface of the freewheel (20), while the free ends of the levers (16-16') remain separated from the arms (19) of the wards (4) and, therefore, do not exert any force on them.
  • a tension spring (18) is mounted on the side legs (17) of each ward (4), which tries to move its respective ward in opposite direction to the driving force of the corresponding lever (16) or (16'), so that when these cease acting on the wards due to the movement of one of the doorknobs (24), the head parts (8) of all the wards (4) remain in their position of maximum movement upwards or downwards, depending on the group they belong to, and finding themselves positioned in the path of the protrusions (13-13') of the frame (2), preventing its horizontal movement and, therefore, the unlocking of the lock.
  • the other end of the spring (18) is attached to the leg (17) of the next ward belonging to the other group, so that each spring (18) will cause the simultaneous movement of the wards belonging to different groups. This position is shown in figure 2A.
  • each ward needs to be moved along a different distance, so that the ends of their heads and tails end up at the same level as the paths of the protrusions (13-13'), allowing the movement of the frame (2).
  • the key (10) is required, which is also an object of this invention.
  • the key (10) has a profile (15) such as those shown in detail (d) of figure 7B, preferably cross shaped, wherein the horizontal part is free of any vertical protrusions to provide a tight fit within the slot (14) created by the plates (6-6') of the ward carrier support (5), through which the key (10) is introduced from the exterior of the lock housing (1) and which presents a silhouette that matches its profile (15).
  • Said key (10) includes two wings (33-33'), one directed upwards and the other downwards, which are cut so as to form teeth (34) with different individual depths, depending on the distance required by the corresponding ward (4) when moved by the spring (18) to position it outside of the path of the protrusion (13) or (13').
  • the wards (4) will move, actuated by the spring (18), and butt at the corresponding teeth (34) of the key, said teeth limiting the movement of the wards (4) so that their head parts (8) and tail parts (9) will remain retracted and outside of the reach of the protrusions (13-13'), thus allowing the movement of the frame (2).
