Abstract

The essence of the invention is including in the body of the lock such mechanisms which with their dynamic provide for several functions of the lock: automatic locking when closing the door, panic function (complete unlocking of the lock by exerting pressure on the doorknob from the inside), electromagnetic function (unlocking the lock with the doorknobs with previous use of a coded electromagnetic key or code), locking of the lock in several positions (from one to four) and providing the door onto which such a lock is mounted to be open in both directions just by exerting pressure on the doorknobs. The lock unlocks by turning the key of the auxiliary cylinder lock for 90 degrees, or by turning for 45 degrees of the related doorknobs.

Description

Multifunctional automatic mechanical and electrical-mechanical lock for door

1. Technical field on which the invention is relating to

The door lock is relating to the field of mechanical engineering, and is used in the construction field. It is used for protection of property of any kind. According to the International Patent Classification (IPC) the invention's class is identified, classified, and determined with the symbol E05, wherein locks, keys and alike are disposed.

2. Technical problem

The people, from earliest until present times had and have the need to secure specific areas from entering by uninvited persons, with the objective to protect private or state property, or to feel secure in those areas. For this purpose, people have developed various locking systems, so called locks.

3. Description of the present state of the art

Mechanical systems for locking - locks, exist in different shapes, forms and sizes. Some locks are used for locking with blocking in one position, some in two, and some in more positions. There are locks with their own key and locks using an auxiliary cylinder lock with their own key. The locks using auxiliary locks and which are only solving the problem of locking, i.e. blocking with the movement of specific metal bars and rods, are called locks for doors. The proposed lock is a specific construction of a lock for door, which solves the problem of multiple securing and uses an auxiliary cylinder lock for solving the combinations and the key.

4. Description of the technical problem The proposed multifunctional automatic mechanical and electrical/mechanical lock for door is designed within standard dimensions. The mechanisms in the lock are created in such a way that their dynamics provide for significant protection, which takes place in parallel with rationalization of parts and springs , as well as rationalization of manipulative moves for locking and unlocking. Namely, locking is completely unnecessary with this lock, while the unlocking from the outside and inside is done directly through the cylinder lock or directly through the doorknobs, depending on the type of the lock. Therefore, the lock is named automatic. The lock is unlocked only with the key of the cylinder lock, or with the doorknobs, if an electronic coded key is used, while the locking is done automatically with pushing (from the inside) or pulling (from the outside) of the door. While entering or exiting the premises, the latch is positioned in a such a way that while it goes out of the lock, and while it goes into the opening of the door frame, it releases a helical spring and the central gearbox pulls out the deadbolt for horizontal locking. The mechanisms in the lock are created in such a way that behind the inner part of the latch at the same moment an inner safety device is located which does not permit the latch to move back. Practically, when one wants to enter the premises secured with this lock, the key of the cylinder lock pulls the deadbolt for horizontal locking, and after that with the same movement (not more than 90 degrees), it pulls the latch as well. In such a way, the lock is completely unlocked. When the key of the cylinder lock is released from the pressure the latch goes backwards, i.e. exits from the body of the lock, while the deadbolt for horizontal locking remains inside. When the cylinder lock key is removed from the cylinder by turning it in the opposite direction for 90 degrees, and when the person enters the premises, the lock is locked by pushing the door. To leave the premises the person needs to turn the key set on the inside of the cylinder lock for 90 degrees and the lock with be unlocked. When the person goes outside, one needs only to pull the door in order to lock the lock. So, the operation of locking from the outside and inside is avoided, and the unlocking is done by turning the key of the cylinder lock for 90 degrees.

Unlocking is possible also by pressing the doorknob (panic function). This is possible by putting a stationary (Φ) spring on the lever follower, which when turned it presses down the inner safety device, while the latter moves the central gearbox, which then moves the other mechanisms in the same way as when unlocking with a key.

In addition to this lock, a specific mechanism for upper and lower locking is proposed, which consists of fixed plates for doors, boxes, bolts-plates, which are planted on Φ cylinder sticks, onto which initially helical springs are mounted. The bolt-plates, through inclined channels and through also inclined channels but in the opposite direction on the boxes in which they are placed, are pulled from the Φ3 connectors, connected to their carriers placed in the body of the lock and are pulled into the boxes by retracting the springs with the unlocking of the automatic locks, locking in four positions. The bolt-plates under the force of the retracted helical springs, with the help of the helical spring of the inner safety device in the lock through the central gearbox, the carriers and the connectors, automatically go out of the boxes with locking, i.e. with closing of the door.

When the bolt-plates are extracted from the boxes, i.e. when the automatic lock locking in four positions is locked, the bolt-plates cannot go backwards if pressure is exerted on them, because on each end of the channels of the boxes there are widened parts on the boxes, and inside them the ends of the connectors Φ3 enter, and they cannot move along the channels. Because of that, the bolt-plates cannot be pulled into the boxes, nor can the lock be unlocked when pressure is exerted on them in horizontal direction. This lock is proposed in four versions and several sub-versions, depending on the use of the premises which is secured. For this purpose, inside the body - box of the lock other parts are added - carriers of connectors for two horizontally placed bolt-plates, above the lock, and below the lock of the door, an electromagnet, safety device of the lever follower, as well as drivers of the safety device of the lever follower and the Φ spring for pulling the blocking device of the inner safety device. The sub-versions of the locks are produced by turning the carrier of the blocking device for 90 degrees with a screwdriver and of the driver of the safety device of the lever follower. By turning the carrier of the blocking device for 90 degrees, because of the eccentric relation of the carrier of the safety device with the driver of the Φ spring, the driver changes the orientation of the Φ spring, and it loses its function for unblocking of the inner safety device, i.e. the lock remains unlocked even when the latch is moved backwards, i.e. when it goes out of the front plate of the lock.

By turning the driver of the safety device of the lever follower for 90 degrees with a screwdriver, because of its special function the safety device of the lever follower is moved up, so the driver is unblocked and by pressing the doorknob which is put in the square opening of the lever follower, the lock is unlocked.

The safety device of the lever follower is moved up and unblocks the lever follower, and when the electromagnet is charged with electricity, the lock will be unlocked with the doorknobs. That is how the lock obtains its electromagnetic function. With this automatic, mechanic and electro mechanic lock all usual standard cylinder locks can be used. The dimensions are such, that the lock can be used with most common wooden doors. The production technology of the said lock is very simple. A number of lock parts are made with cutting, bending and punching. Other parts are made with the so-called sinter technology and another part with rotational automatic machines. All lock parts are made of steel, while the friction and use of springs are minimal, so the lifetime of the lock in the construction industry will be increased for several times.

To secure the locks from breaking, security door plates (covers) are used.

The basic versions of the locks are the following: 1. Automatic mechanical lock for door, which locks in two positions (picture 11 ) with subversions: a) Panic function - with the doorknob from the inside the lock is completely unlocked, while the outside doorknob is blocked (picture 2); b) The two doorknobs are in function, i.e. the door can be made open in the two directions, which is done with an intervention on the lock when the door is open (picture

3).

2. Automatic mechanical lock for door, which locks into four positions (picture 4) with sub-versions: a) Panic function - with the doorknob from the inside the lock is completely unlocked, while the outside doorknob is blocked (picture 5); b) The same lock, transformed into a lock which locks in one position, which is done with an intervention on the lock when the door is open (picture 6). c) The two doorknobs are in function, i.e. the door can be made open in the two directions, which is done with an intervention on the lock when the door is open (picture

7).

3. Automatic electro mechanical lock for door, which locks into two positions (picture 8) with sub-versions: a) The two doorknobs are in function, i.e. the door can be made open in the two directions (picture 9).

4. Automatic electro mechanical lock for door, which locks into four positions (picture 10) with sub-versions: a) The same lock, transformed into an automatic electro mechanical lock for door which locks in one position (picture 11). b) The two doorknobs are in function, i.e. the door can be made open in the two directions

(picture 12).

The most complex version of the lock (version 4) is done by adding parts to the simplest version (version 1 ) Picture 13 shows the lock completely unlocked with a key.

Picture 14 shows the lock completely unlocked with a doorknob. Picture 15 shows the lock ready for locking. Picture 16 shows the lock completely locked. Pictures 17, 18 and 19, show the most functional parts of the proposed lock: central gearbox, blocking device of the inner safety device and the inner safety device. Picture 20 shows the set for upper and lower locking - unlocked position. Picture 21 shows the set for upper and lower locking - locked position. The body of the lock consists of: box (1), front plate (5), cover (3), cylindrical distance keepers (16). The body includes the following basic parts: deadbolt for horizontal locking (7), latch (4), central gearbox (13), lever follower (17) of the latch (4), inner safety device (35), blocking device (36), helical spring (37), carrier of the blocking device (31), rods (25 and 26), helical spring (11) for the latch (4) and the Φ spring (12) for the blocking device (36). These parts provide for the automatic function of the lock as follows: when the central gearbox (13) rotates with the help of the lever follower of the cylinder lock positioned in the opening (74), pulling out the holder (15) in the direction of unlocking, it moves first the deadbolt for horizontal locking (7) and the inner safety device (35), and after that, through the rod (26), with the other rod (25) pulls the latch (4) into the body of the lock by retracting the helical spring (11). At the same time the rod (25) moves the blocking device (36) and sets its upper bent part above the upper part of the inner safety device (35). When the central gearbox (13) is released from the pressure of the lever follower of the cylinder lock, the helical spring (37) moves upwards the inner safety device (35) which is held by the bent part of the blocking device (36). The helical spring (11 ) moves back the latch (4) and sets its front part extracted from the body of the lock. As the latch moves backwards (4) the rod (25) is also moved, connected at an angle with the other rod (26). Further to that, and because of the specific construction of rod (25), the Φ spring (12) which is connected to the latch (4), and which lies on the upper part of rod (25) does not touch the blocking device (36) and the inner safety device (35) remains blocked, while the lock is unlocked, and ready to be locked. When the door is locked, the latch (4) in contact with the door frame, because of the specific construction (on one side it is KOS), glides along the edge of the frame and enters into the body of the lock, and in one moment goes out of the body of the lock, and enters the opening made for it in the door frame. During the exiting of the latch (4) from the body of the lock, the Φ spring (12) touches the blocking device (36) and it pulls it along the carrier (21). This happens because now the Φ spring (12) does not lean on the upper part of the rod (25) and its orientation is not changed. Now the helical spring (37) moves the inner safety device (35) upwards, which then moves the central gearbox, which moves the deadbolt for horizontal locking (7) which with one part goes out of the body of the lock. At the same time, one KRAK of the central gearbox (13) goes under the deadbolt for horizontal locking (7) and it secures it. The inner safety device (35) moving upwards under the pressure of the helical spring (37) with its upper part sets itself behind the back part of the latch (4) and it secures it. In such a way, the lock automatically locks in two points, with the deadbolt for horizontal locking (7) and the latch (4).

The following parts of which the proposed lock consists of are parts which provide for locking in two additional positions of the door (above and below the lock). These are the following parts: in the body of the lock: upper carrier (23) and lower carrier (24), and outside of the lock - connector Φ3 (50), fixed plate for door (42), box (2), cylinder sticks (40), helical spring (10), and bolt-plate (46). The fixed plate for door (42), the box (2) and the cylinder stick (40) are static system. The connectors Φ3 (50) are bent for 90 degrees on both ends. One end goes into an inclined channel of the box (2), in the also inclined, but in the opposite direction channel of the bolt-plate (46), while the upper and lower carriers are planted, thru their openings (24 and 23) on the other ends of the lock, and above the lock.

By turning the central gearbox (13) in the unlocking direction of the lock, one of its legs moves downwards the upper carrier (23), while the other leg goes upwards, moving the lower carrier (24). The upper and lower carriers (23 and 24) move the connectors Φ3 (50), while they force the bolt-plates to go into the box (2), which in turn retract the (10).

By unblocking the inner safety device (35) the helical springs (10), with the help of the helical spring (37) push the bolt-plates (46) and extract them with one part out of the box (2). On each end of the inclined channels of the box (2) widenings are made, into which the bent ends of the connectors Φ3 (50) sit, and do not allow the bolt-plates (46) to retract into the box (2), by exerting pressure horizontally. In such a way the bolt-plates (46) are secured, and the lock locks into two more positions, i.e. locks in four positions.

The last parts which make the multifunctional mechanical and electro mechanical lock for door are the parts which allow for the electromechanical function and the sub-versions. These are: electromagnet (31 ), safety device (20), driver (67), static Φ spring (33) and driver (58) for the Φ spring (12).

When the lock includes an electrical magnet (31 ), it does not need a key for unlocking. Then the lock is unlocked with the doorknobs, after the lever follower is unblocked (17). In order to turn the lever follower (17) a coded electrical magnetic key is needed, or a code to give a signal, to close the electric circuit of the electrical magnet (31). Then, the electrical magnet (31) attracts the safety device (20) which moves and releases the lever follower (17) so that it can be turned. Bu turning the lever follower (17) the Φ static spring (33) which is fixed onto it moves downwards the inner safety device (35), which through the central gearbox (13) moves all other mechanisms. When the pressure on the doorknobs which turn the gearbox (13) stops, the doorknobs under the pressure of their spring, and the helical spring (11) return into their previous condition, returning the lever follower (17) and the latch (4), while the inner safety device (35) remains blocked from the blocking device (36). In such a way the lock unlocks and is ready for automatic locking when the door is closed.

In the same manner as above, the lock unlocks with the doorknob under panic function mode. In such a way, the electrical magnet (31) is missing, as well as the safety device (20) and the driver (67), while the outside doorknob is blocked. hen with a screwdriver, when the door is open, the carrier (21) is turned off the bJocking device (36) for 90 degrees clockwise, because of the eccentric relation between the earner (21 ) and driver (58) of the Φ spring (12), the driver (58) is moved upwards and it moves the Φ spring (12) also upwards, i.e. it changes its orientation, so that when the latch (4) is returned backwards, i.e. with the front part extracts from the body of the lock, the Φ spring (12) does not pull the blocking device (36), and the lock remains functioning only with the latch (4). In such a way, the proposed sub-versions b), from version 2 and a) from version 4 are realized. In order the lock to be unlocked completely from the outside and inside with pressure on the doorknobs, i.e. the door to be open in both directions (irrespective whether it is mechanical or electrical mechanical) the safety device (20) and the driver (67) are included. Namely, by turning the driver (67) for 90 degrees with a screwdriver when the door is open, the safety device (20) is moved upwards and the lever follower (17) is unblocked. With the doorknobs, the lock is unlocked. In such a way, the proposed sub-versions b) from version 1, c), from version 2, a) from version 3, and b) from version 4, are realized.
