Definitions

• the object of the present invention falls within the sector of locksmithing and more specifically mechanical-motorised locks.
• the invention relates to a three-point lock with deadbolts and self-locking on the deadbolts.
• a countless number of motorised lock models are known in the state of the art, said models comprising a load shaft and closing hooks, where the opening process is motorised or carried out manually by a key, and the closing process is carried out by loading the load shaft. At the moment when said load shaft is loaded, the closing hooks are triggered and, therefore, a greater closing force is applied to the elements that position the door (or window).
• the invention relates to a self-locking mechanical-motorised three-point lock.
• the lock of the present invention does not have any load shafts for performing the closing operation.
• the configuration of the lock allows for smooth and frictionless closing by means of an electrical command sent to the motor of the lock. Once closing has been performed, the deadbolts (hooks) that perform this action are self-locked, i.e., it is impossible to fold them manually or with external tools. They would only open mechanically, by key, or electrically.
• the lock comprises a central assembly and upper and lower assemblies wherein each of the assemblies has a deadbolt (hook or closing point).
• deadbolts are linked to a mechanical central transmission and to upper and lower satellite transmissions.
• the mechanical central transmission and the satellite transmissions are linked to each other via an upper espagnolette bolt and a lower espagnolette bolt, which allow the transmission of movements to synchronise the opening/closing movements of the three locking points (deadbolt, upper deadbolt and lower deadbolt).
• the lock incorporates a coil which, if energised, inhibits manual opening by the key-cylinder. This increases security against attacks on the cylinder by bumping, impressioning, breaking, etc. In these cases, the cylinder of the lock can be rotated, but the lock does not respond as long as the inhibition is active.
• the lock has also been fitted with guards for the espagnolette bolts to prevent their tampering and thus also prevent the lock from being opened by an attack on the espagnolette bolts.
• the lock can also have two central steel guards, which prevent tampering of the internal elements by attempts to drill holes in the lock body.
• said system has a coil that attracts an inhibiting lever, which in turn is connected to a mechanical central transmission for manual opening by key. Once the coil is activated, it attracts the inhibiting lever that connects the mechanical central transmission and a cylinder slider, thus being in idle rotation and thus preventing opening by key.
• the inhibiting system comprises a sliding lever, connected to the mechanical central transmission by an inhibiting lever, and it comprises an inhibiting coil that causes the inhibiting lever to release from the cylinder slider.
• Self-locking is achieved by positioning, in each assembly, a self-locking shaft, which is connected to the mechanical central transmission and to the corresponding satellite transmissions, within a slotted hole comprised in the locking deadbolts and said slotted hole has a section arranged at an obtuse angle with respect to the longitudinal direction of movement with respect to the longitudinal movement of the transmissions (mechanical central transmission and upper and lower satellite transmissions) which prevents the corresponding deadbolt from rotating. This angle is preferably 108°.
• the lock also comprises a motor, connected to a bit, which drives a die with two bearings configured to slide along a flute of the bit.
• the motor is also connected to the mechanical central transmission.
• the lock also comprises a positioning rod which, via a spring, positions the deadbolt of the mechanical central transmission in the open or closed lock position.
• the lock comprises a cylinder sliding with the ability to move in two directions, thus allowing the lock to be opened or closed.
• the inhibiting coil is electrically activated, so that it attracts the inhibiting lever disengaging it from the cylinder slider, which in turn is connected to the central transmission and makes it impossible for the lock to open mechanically by key.
• the lock can be opened electrically under these conditions.
• opening by key can be inhibited if the inhibiting coil is energised, so that said coil attracts the inhibiting lever which is connected to the cylinder slider, leaving it free and non-actuated, so that the lock cannot be opened by key.
• the lock comprises an electronic circuit configured to receive electrical signals which activate the motor, which in turn is configured to move the deadbolts.
• the electronic circuit is always powered with 12V DC voltage.
• the lock does not work until it faces the central striker which, in a preferred embodiment, comprises a magnet.
• the magnet excites a reed in the electronic circuit, at which point the lock is actuated and the deadbolts rotate to the closed lock position.
• a signal is given to electrically open the lock.
• the lock comprises two 12V DC power supply wires and a third wire which, when set to negative, sends the electrical opening signal. If this third wire is left in a negative state continuously (as if it were a switch) after giving the opening signal, the lock remains open continuously as long as this state is maintained. When the negative signal is eliminated, the lock, when facing the striker and detecting the magnet, locks the door again. This is the swing or free passage function.
• the electronic circuit can also receive a constant voltage so that the lock is permanently activated in order to leave the door in a swing state, with free access by simply pushing it.
• the lock can also comprise a magnet, positioned in the corresponding striker (element in which the deadbolts are housed when they are in the closed position).
• the lock can comprise a circuit that detects, by means of the magnet, that the window/door is in a position ready for closing, and it can electrically activate said closing.
• the lock is preferably made entirely of stainless steel (except for the rivets).
• the three deadbolts are automatically released and held in the open position by the positioning rod of the central transmission.
• the three deadbolts are held in the closed position, also by the positioning rod of the central transmission, and are self-locked by the self-locking shaft which rotates through the 108o slotted hole.
• the lock can be opened remotely, it can be used on swing doors/windows and it can comprise open/closed status signalling.
• Figure 1 shows a plan view of the self-locking mechanical-motorised three-point lock installed on a front (2).
• the lock is shown in the closed position, with the deadbolts (4, 4.1, 4.2) (locking points) in the closed position, housed in receiver holes in a striker (32).
• the lock can comprise a housing base (19), which is a body inside of which the mechanical and electrical elements corresponding to a central assembly (1) (central locking point) are housed.
• the lock comprises an upper assembly (1.1) and a lower assembly (1.2) which, in an exemplary embodiment, are housed in secondary closing housing bases (19.1, 19.2).
• the lock described is a high security lock.
• the central, upper and lower assemblies (1, 1.1, 1.2) are linked to each other by upper (3.1) and lower (3.2) espagnolette bolts.
• the central assembly (1) comprises a mechanical central transmission (16) and an electrical central transmission
• the upper and lower assemblies (1.1, 1.2) comprise upper and lower satellite transmissions (7.1, 7.2) connected via the corresponding upper and lower espagnolette bolts (3.1, 3.2) to the mechanical central transmission (16).
• both the mechanical central transmission (16) and the satellite transmissions (7.1, 7.2) are preferably plates which can comprise a plurality of projections, inlets, holes and/or a combination thereof.
• both the central deadbolt (4) and the upper and lower deadbolts (4.1, 4.2) are "parrot beak" deadbolts.
• they consist of a plurality of steel sheets joined together.
• FIG. 2 shows a detail of the central assembly (1).
• the central deadbolt (4) is connected to a mechanical central transmission (16) plate, in a manner that swivels around a deadbolt rotation shaft (5).
• the central deadbolt (4) further comprises a self-locking slotted hole (18) inside of which a self-locking shaft (15) is moved, which is connected to the mechanical central transmission (16) plate.
• the self-locking slotted hole (18) has a configuration with a first section arranged at a certain inclination with respect to the longitudinal direction of displacement of the mechanical central transmission (16) plate and with a second section arranged in said longitudinal direction of displacement of the mechanical central transmission (16) plate.
• the first section of the self-locking slotted hole (18) is inclined at an obtuse angle with respect to the longitudinal direction of movement of the central transmission (16) plate. This inclination is preferably 108°.
• the three deadbolts (4, 4.1, 4.2) of the lock comprise self-locking slotted holes (18). Furthermore, the upper and lower satellite transmissions (7.1, 7.2), as well as the mechanical central transmission (16), have locking shafts (15) which act as the locking shaft (15) of the mechanical central transmission (16) described above. Thus, the three locking points are self-locking.
• the movement of the mechanical central transmission (16) plate is guided by the displacement of a first drive shaft (8) which is moved guided in a transmission slotted hole (13) and by the movement of a second drive shaft linked to a positioning rod (9) which also form part of the mechanical central transmission (16).
• the upper and lower satellite transmissions (7.1, 7.2) comprise corresponding first upper and lower drive shafts (8.1, 8.2) which are moved guided in transmission slotted holes (13.1, 13.2) and by the movement of second drive shafts linked to upper and lower positioning rods (9.1, 9.2) which are part of the upper and lower satellite transmissions (7.1, 7.2), respectively.
• the positioning rod (9) is crossed upwards so when attempting to lift the deadbolt (4) with any type of tool (e.g., a screwdriver or a lever), the positioning rod (9) prevents said displacement from being carried out.
• any type of tool e.g., a screwdriver or a lever
• Figures 3A-B show detail views of the upper assembly (4.1) and the lower assembly (4.2), respectively.
• the deadbolts (4, 4.1, 4.2) swivel about the corresponding rotation shafts (5, 5.1) until they leave the corresponding recesses of the striker (32), thus moving the deadbolts from the closed position to the open position (positions that correspond to the closed position and the open position of the lock).
• the self-locking slotted hole (18) rotates, so that the self-locking shaft (15) goes from being housed in the second section to being housed in the first section of said self-locking slotted hole (18), the deadbolt (4) being locked in said position.
• a second drive shaft (17) which is connected to the mechanical central transmission (16) plate (there is also a second upper drive shaft and a lower drive shaft (17.1, 17.2) in the corresponding upper and lower satellite transmission (7.1, 7.2) plates), this movement moves the positioning rod (9) to one side or the other, rotating about a rod rotation shaft (6) (in the upper and lower assemblies (1.1, 1.2) they have been referred to as upper and lower positioning rod (9.1, 9.2) and upper and lower rod rotation shaft (6.1, 6.2), respectively).
• a spring (10) arranged over the positioning rod (9) assists in the correct positioning and prevents the corresponding deadbolt (4) from being moved out of its position (both in the open position and in the closed position) (the same applies to the upper and lower assemblies (1.1, 1.2) with an upper spring (10.1) and a lower spring (10.2) and the corresponding upper and lower positioning rods (9.1, 9.2)).
• the positioning rod (9) leaves the satellite transmission (7) and the central transmission (16) positioned through the spring (10) when the "parrot beak” deadbolt (4) is inserted into the upper and lower secondary housing base (39). Moreover, when the "parrot beak” deadbolt (4) is in the closed position, the satellite transmission (7) is moved in the other direction and the deadbolt (4) is left secured via the self-locking shaft (15) and the positioning rod (9) so that the deadbolt (4) cannot be moved in the opening direction by means of external tools. This effect can also be applied to the mechanical central transmission (16).
• the positioning rod (9) pivots on the rod rotation shaft (6), which in turn is connected to the mechanical central transmission (16) (in an exemplary embodiment, it is securely connected, by means of a rivet, to the housing base (19)).
• a second drive shaft (17) is also connected to the mechanical central transmission (16) and linked to the positioning rod (9) that comprises a positioning slotted hole (21) such that, when the mechanical central transmission (16) is moved, it causes the second drive shaft (17) to move and said second drive shaft causes the positioning rod (9) to move.
• a spring (10) is arranged around the positioning rod (9) and exerts pressure on the second drive shaft (17) such that, both when the lock is open and when the lock is closed, the spring (10) secures the position of the positioning rod (9), assisting in the self-locking of the deadbolt (4).
• the self-locking assembly works in combination with the positioning rod (9). If the lock would not have the positioning rod (9), the deadbolt (4) could be lifted using external tools such as a screwdriver or lever.
• the lock can comprise a cylinder (14), that can be actuated with a key, and having a high cylinder cam (11) as shown, for example, in figure 2 .
• said cylinder (14) acts through the cam (11) by moving the cylinder slider (12) so that the mechanical central transmission (16), when being moved in one direction or the other, causes the self-locking shafts (15) to move in the corresponding self-locking slotted holes (18).
• this movement is transmitted to the upper assembly (1.1) and to the lower assembly (1.2) through the upper and lower espagnolette bolts (3.1, 3.2), causing the deadbolts (4, 4.1, 4.2) to swivel.
• the cylinder slider (12) comprises a window on which the cylinder cam (11) acts, moving said slider.
• Figure 4B shows a detailed view of a section of the die (26) showing the bit (28) and the balls (31). This section is determined by the plane BB marked in figure 4A .
• the balls (31) are bearing balls which, when sliding along the bit (28) in one direction or the other (depending on whether the lock is opened with a key or electrically), cause the die (26) to move the plate of the mechanical central transmission (16) and said mechanical central transmission, in turn, moves the upper and lower espagnolette bolts (3.1, 3.2), which causes the plate of the upper and lower satellite transmissions (7.1, 7.2) to move so that the lock is closed or opened either electrically or mechanically.
• Figure 4C shows a perspective view of the die (26) and the bit (28), showing how they are linked, and how the bit (28) passes through the die (26).
• the lock can comprise an inhibiting assembly.
• Said assembly includes an inhibiting coil (29) which, when it receives a certain voltage, attracts an inhibiting lever (30), releasing the cylinder slider (12) and thus allowing it to move.
• an inhibiting coil (29) which, when it receives a certain voltage, attracts an inhibiting lever (30), releasing the cylinder slider (12) and thus allowing it to move.
• the voltage determined in order for the inhibiting assembly to work is 12V DC.
• This voltage can come from any power supply and with any control system, such as, for example, push buttons, proximity readers, etc.
• the lock comprises an inhibiting assembly
• said assembly has an inhibiting lever (30) which is able to rotate about an inhibiting lever rotation shaft (36) which is connected to the mechanical central transmission (16). It also has an inhibiting lever spring (37) that keeps the inhibiting lever (30) connected to the cylinder slider (12).
• the cylinder cam (11) acts on the cylinder slider (12) which, via the inhibiting lever (30), moves the mechanical central transmission (16) which, with its displacement, causes the upper and lower espagnolette bolts (3.1, 3.2) to move and the deadbolts (4, 4.1, 4.2) to rotate.
• the inhibiting system is optional, i.e., inhibition is not necessary for lock operation. It is included in the embodiments of the lock where the user wishes to inhibit opening with the key, (the key is allowed to rotate but the deadbolts are not).
• the lock can comprise an inhibiting lever (30), but in this case it is always arranged inside the cylinder slider (12) so that the lock always opens mechanically with a key, and of course it always opens electrically.
• the lock does not need to have the inhibiting coil (29).
• the lock would work like any other lock, mechanically with just a key. In this case, it is always necessary to use a key to open or close the lock in order to open it mechanically.
• the lock does comprise an inhibiting system
• said coil attracts the inhibiting lever (30) and disengages it from the cylinder slider (12) whereby, when mechanically rotated with a key (inserting the key into the cylinder (14)), the cam (11) moves the cylinder slider (12) to either side, freely, and without rotating the deadbolts (4, 4.1, 4.2), i.e., without closing or opening the lock.
• the cam (11) moves the cylinder slider (12) to either side, freely, and without rotating the deadbolts (4, 4.1, 4.2), i.e., without closing or opening the lock.
• no voltage has been applied to the coil
• a cylinder cam (11) when a cylinder cam (11) is rotated (by rotating a key in said cylinder (14)), it moves the cylinder slider (12) which is connected to an inhibiting lever (30) and which causes the mechanical central transmission (16) to move.
• the inhibiting lever (30) is connected to the mechanical central transmission (16) via an inhibiting lever rotation shaft (36) about which said
• the inhibiting lever is a floating joint which is connected via the inhibiting lever rotation shaft (36) to the mechanical central transmission (16).
• the inhibiting lever spring (37) connects said inhibiting lever (30) to the cylinder slider (12).
• the inhibiting lever spring (37) causes the inhibiting lever (30) to come in contact with the cylinder slider (12) again so that, when the lock is actuated with a key in the cylinder (14), it causes the deadbolts (4, 4.1, 4.2) to rotate, causing the lock to open or close.
• the inhibiting lever (30) is connected to the cylinder slider (12) via a spring (37) of the inhibiting assembly which is tensioned over an inhibiting assembly spring stop (38) to allow, if the inhibiting coil is not energised with the necessary voltage, the displacements of the mechanical central transmission (16), and therefore of all the assemblies (1, 1.1, 1.2), of the lock to open or close it mechanically, when the cam (11) of the cylinder (14) acts on the cylinder slider (12).
• the central assembly (4) comprises a microswitch (27) (shown, for example, in figure 4C ), which is fixed and attached to the circuit (34), which is actuated by the die (26) when it is moved by the action of the bit (28) and the balls (31).
• the microswitch (27) is preferably a switched microswitch (C-NO-NC) which is part of the circuit (34).
• C-NO-NC switched microswitch
• the electronic circuit (34) includes two 12V DC power supply wires, an opening and/or swing signal wire, and three wires connected to the microswitch (27).
• the lock can also comprise a magnet (33) installed on the striker (32).
• the magnet (33) detects said position (closed door or window) so that, when an external voltage is applied through a connector (35) of the electronic circuit (34) wherein said electronic circuit (34) is connected to the motor (20), the motor (20) rotates the bit (28), moving the die (26).
• the die (26) sliding through the balls (31) along the flute of the bit (28), moves the mechanical central transmission (16), causing opening or closing by swivelling the central deadbolt (4) in one direction or the other.
• the open or closed position of the central deadbolt (4) is recognised by the microswitch (27) which is actuated by the die (26) when it is moved along the bit (28).
• the lock also allows the door to work in swing state.
• the deadbolts (4, 4.1, 4.2) are permanently housed inside the housing base (19) and the secondary housing bases (39) in order to open the door/window by simply pushing it.
• the deadbolts (4, 4.1, 4.2) instead of sending an electrical signal through the connector (35) to the circuit (34) to activate the motor (20), the deadbolts (4, 4.1, 4.2) are kept in the open position, i.e., housed in the housing base (19) and secondary housing bases (39).
• the lock comprises an upper espagnolette bolt cover (23) arranged over the upper espagnolette bolt (3.1), a lower espagnolette bolt cover (24) arranged over the lower espagnolette bolt (3.2), a metal electronic box (25) arranged over the electronic circuit (34) and/or a central steel guard (22) arranged over the mechanical central transmission (16).
• the lock has a central steel guard (22)
• said guard protects the lock from external attacks such as drilling or similar.
• the self-locking assembly of the central deadbolt (4) (and of the upper (4.1) and lower (4.2) deadbolts) prevents unwanted activation of the lock, thus preventing unauthorised opening of the door.
• the locking system incorporates the positioning rod (9) as shown, for example, in figure 2 . When the deadbolt (4) is in the closed position, the positioning rod (9) does not allow it to return through the self-locking slotted hole (18).
• the self-locking system does not prevent the door from opening when the lock is activated by any of the previously described methods, i.e., by a key actuating the cylinder (14), or electrically through the electronic circuit (34), since in these cases the door is opened by moving the mechanical central transmission (16) using the methods described above.
• Figures 6A-B show the lock, in the open and closed position.
• Figure 6A shows the deadbolts (4, 4.1, 4.2) in the open position, and figure 6B shows them in the closed position (housed in holes in the striker (32)).
