Description

Technical field

The invention relates to the field of construction, and in particular to doors, in particular burglar-resistant doors for locking rooms and protecting them from unauthorized entry.

State of the art

Currently, there are various doors designed to lock rooms and protect them from unauthorized entry.

However, the increase in burglar resistance of burglar-resistant doors known in the prior art is achieved mainly due to improvements in the door lock and / or increase in their number.

For example, Chinese patent CN 202520186 discloses a burglar-resistant door comprising a door leaf pivotally mounted on a door frame and twenty door locks located close to each other.

Burglar resistance of the specified door is ensured by the user selecting several locks and then locking these locks in such a way that information about how many locks and which ones are used is available only to the door user and is not known to the potential cracker.

The disadvantage of this burglar-resistant door is the location of the locks in one door and, thus, providing easy access to them and cutting them out of the door leaf by known methods for unauthorized access to the premises by an attacker.

RU 2350727 describes a system for preventing unauthorized entry into a room, comprising door locking devices and at least one locking device that cannot be detected externally, for example, remotely-mounted, mounted to partially open the door and prevent it from being opened further. The system prevents an intruder from entering the room after breaking in visible locking devices before the arrival of security or forces him to stop further attempts to enter the room.

The system according to patent RU 2350727 provides for the implementation of a lock that is not detectable from the outside, however, one of the locking devices is located in the door leaf so that it is accessible and manipulated. In addition, the disadvantage of the known system is that when an attacker tries to penetrate into the room, the external lock will be damaged in any case, which creates the need for a subsequent replacement of the lock or the entire door leaf after an attempted break-in.

The closest analogue of the invention is a burglar-resistant door, disclosed in Chinese patent CN 201236605 and containing a first door leaf that is external and containing at least one keyhole, a second door leaf that is internal and opposite the first door leaf and that opens in relation to to it in the opposite direction, at least one mortise locking device containing a keyhole and at least one bolt, made with the possibility of inter actions with a corresponding response device, and a door frame to which the first and second door leafs are each attached by at least two hinges. The inner door leaf is bulletproof, and the outer door leaf is burglar resistant. Both door leafs are equipped with locks made by tamper-resistant drilling method.

Despite the fact that the presence of a second internal door makes it difficult to break in and increases the exposure time for the door to enter the room and that locks are provided in this door that are protected from drilling, locks made in the external door may be subject to cutting by an intruder.

In addition, the second inner door according to patent CN 201236605 is bulletproof, which increases the cost of manufacturing such a door and is not necessary when installing the door to close residential and industrial premises.

Thus, most of the known burglar-resistant doors have the disadvantage that the lock is usually located on the outer surface or inside the outer or only door leaf, and thus it is freely available for manipulating the lock for breaking the door.

A lock located in an external or single door leaf and cut out of it, ceases to fulfill the function of locking the door and prevent opening the door.

Therefore, despite the large number of devices and methods of protection against burglary, there is a need to increase the reliability of the door in relation to burglary by manipulating the lock, in particular by cutting it out of the door leaf.

Disclosure of invention

The present invention is the creation of a reliable door that is resistant to burglary by manipulating the lock, in particular by cutting it out of the door leaf.

The objective of the invention is solved due to the fact that in the door containing the first door leaf containing at least one hole for the key, the second door leaf located opposite the first door leaf and opening with respect to it, at least one mortise lock a device comprising a keyhole and at least one crossbar configured to interact with a corresponding response device, and a door frame to which the first and second two are attached each leaf through at least two hinges, the specified at least one mortise locking device is located in the second door leaf so that the corresponding key can be inserted into the keyhole through the key hole located in the first door leaf, and the response device is located in the second a door leaf, the door further comprising at least one connecting plate fixed to the first door leaf and having at least one opening for pins, the second door skin has an opening for the plate, and when closing the two door leafs possible to insert the plate into the opening for the plate and the possibility of passage of said bolt through said at least one opening for the bolt in the response device ensuring locking plate hole plate.

Thanks to the creation of the proposed burglar-resistant door, a technical result is provided in the form of increasing the door's resistance to burglary due to the latent location of at least one locking device in relation to the external sheet (the sheet with the key hole), since the locking device is not freely accessible and cannot be opened, drilled or cut by an attacker. Thus, the claimed door is reliable and resistant to burglary.

In a preferred embodiment of the invention, the first and second door leafs are made of metal.

In yet another preferred embodiment of the invention, the first and second door leaves are hollow.

The implementation of the invention

Figure 1 shows a preferred embodiment of a burglar-resistant door (1) comprising a door frame (2), a first door leaf (9) and a second door leaf (8) (not shown).

The second door leaf (8) is located opposite the first door leaf (9) and opens in relation to it in the opposite direction, as shown by dashed and solid lines in figure 2.

In the first door leaf (9), two holes (3, 4) are made for the lock keys of two mortise locks (10, 11) (not shown) embedded in the second door leaf (8), and the hole (5) for the key lock for the overhead a lock (12) (not shown) attached to the first door leaf (9) from the inside, that is, from the side of the second door leaf (8). A door handle (6) is attached to the door leaf (9). Door leaves (8, 9) are mounted on at least two hinges (not shown) each.

Despite the fact that, in FIG. 1, the openings (3, 4, 5) for the lock keys are shown to have a substantially circular cross-section, these openings can be made with various other cross-sectional variations without limitation.

According to the proposed invention, the hinges can be any kind of hinges used in the art for attaching door leafs to the door frame, for example, they can be made in the form of screw-in hinges, patch (corner) hinges, cut-in hinges and in the form of combined hinges. In a preferred embodiment of the invention, the hinges are made in the form of loops on ball bearings.

Figure 2 shows a top view in section along the line aa of the burglar-proof door (1) shown in figure 1.

Burglar-resistant door (1) is installed in the doorway on the door frame (2). Burglar-resistant door (1) contains the first door leaf (9) and the second door leaf (8), into which two mortise locks (10, 11) are cut, each of which contains a keyhole (19, 22), a bolt mechanism with a crossbar (19 , 20) of the lock, respectively, and the corresponding lock response devices in the form of blind holes (24, 25). If necessary, each crossbar mechanism or both crossbar mechanisms may contain more than one crossbar.

In this embodiment, the mortise locks (10, 11) are embedded in the second door leaf from the side of the first door leaf, however, in other embodiments, another design is possible. For example, mortise locks (10, 11) can be cut into the second door leaf from the side of the protected room.

The one door lock (12) is attached to the first door leaf (9), containing a keyhole (23), two rods (17, 18) and two gate valves (15, 16), and two connecting plates (13, 14), which provide a detachable the connection of the first door leaf (9) with the second door leaf (8). The implementation of this detachable connection using the connecting plates is described in detail below.

A door handle (6, 7) is attached to each door leaf.

The specified padlock (12) is configured to block access to the mortise locks (10, 11) by moving the rods (17, 18), which in turn move the valves (15, 16) so that they block the holes (3, 4) for lock keys or, conversely, are diverted from the holes (3, 4) for lock keys with providing access through them to the keyholes (21, 22) of mortise locks (10, 11).

The connecting plates (13, 14) are welded to the first door leaf (9) and contain one through hole for the crossbar (not shown). In other embodiments, the connecting plates may be attached to the first door leaf (9) by any other known method, for example, using fixing angles. The second door leaf contains two slit openings for the plates, the shape of which corresponds to the shape of the connecting plates, so that when the first and second door panels are brought together, these plates (13, 14) enter the slot openings for the plates in the second door leaf so that the crossbars ( 19, 20) locks could pass through the bolt holes made in each plate into the corresponding blind holes (24, 25) made in the second door leaf, thus blocking the plates in the slotted holes of the second door canvas (8).

In a preferred embodiment, the connecting plates have one hole for the bolt, however, if necessary, any number of holes for the bolt in each of the plates can be made depending on the number of bolts in the corresponding bolt mechanism.

The present invention is also not limited to this method of releasably connecting the first (9) and second (8) door leafs. For example, although in FIG. 2 blind holes (24, 25) and slot holes are located between the door frame and the mortise locks (10, 11), and the crossbars (19, 20) come out of the mortise locks in the direction of the door frame (2), the blind holes (24, 25) and slot holes can be located on either side of the mortise lock (10, 11), crossbars (19, 20) can exit mortise locks in any direction corresponding to the location of the slot holes, and connecting plates (13, 14 ) can be attached to the first door leaf (9) in any suitable order This plug connection is in place.

Figure 2 shows two door handles (6, 7) located on the first door leaf (9) and on the second door leaf (8), respectively. The location of these handles in the specified door leaf is not limited to the option shown in figure 2, and it can be selected depending on the preferences or requirements of the user or manufacturer.

According to the claimed invention, door leafs (8, 9) of a burglar-resistant door (1) are made of metal, for example steel, aluminum, or metal in combination with wood, or composite material, as well as any other suitable material or combination thereof.

Door leaflets (8, 9) can be hollow or filled with material, for example composite material, or they can be filled with any other materials used in the art for door leafs.

The burglar-resistant door (1) according to a preferred embodiment is locked using the indicated locks (10, 11, 12) by sequentially inserting the corresponding lock keys into the holes (3, 4, 5) for the lock keys and opening the locks (10, 11, 12) through actions carried out using the appropriate keys, which will be described below.

On figa shows a schematic top view in section along the line aa of a burglar-resistant door in accordance with another embodiment of the present invention.

According to the shown embodiment of the invention, the mortise lock (10) is embedded in the second door leaf (8) from the side of the protected room. Thus, it is completely hidden in the second door leaf (8), when viewed in the direction from the first door leaf (9) to the second door leaf (8) and, therefore, is more protected from possible manipulation by an attacker.

In this embodiment, an additional hole (26) for the key is provided in the second door leaf (8) to provide access through it to the keyhole (21) of the mortise lock (10).

FIG. 3 and FIG. 3 a show schematic side views of a burglar-proof door (1) shown in FIG. 2, comprising a mortise lock (10) having a keyhole (21); the corresponding hole (3) for the mortise lock key (10); an overhead lock (12) comprising a keyhole (23), a shaft (17) and a valve (15); the corresponding hole (5) for the lock key of the padlock (12) and the connecting plate (13).

Figure 3 shows a schematic view of a burglar-proof door (1) in the open position, and in Fig. 3a, in the locked position.

As shown in FIG. 3, when the burglar-proof door (1) is in the open position, the valve (15) is moved to a position that does not block the keyhole (3). Despite the fact that in Fig. 3, the shutter (15) occupies a position above the opening (3), the present invention is not limited to this option, and the shutter (15) can occupy a position both above and below the opening in any direction relative to the burglar-proof door (1 ), for example in the longitudinal (A), transverse (B) or in any other direction.

As shown in Fig. 3a, when the burglar-proof door (1) is in the locked position, the valve (15) is moved to the position blocking the key opening (3).

In a preferred embodiment of the invention, the rod (17) or the rod (18) shown in FIG. 2 moves in the direction (A), however, in other embodiments of the invention, the movement of the said rods (17, 18) can be carried out in any other directions, for example in direction (B).

FIG. 4 is a schematic side view of an example of a mortise lock (10) of a burglar-resistant door (1) shown in FIGS. 1-3 in accordance with the present invention, comprising a crossbar (19). It should be noted that a schematic view of a mortise lock (11) with a bolt (20), although not shown separately, is similar to that shown in Fig. 4. Mortise locks (10, 11) can be any known mortise locks containing a crossbar.

The method for opening a burglar-resistant door (1) according to a preferred embodiment of the invention is described in detail below with reference to the accompanying drawings.

In order to translate the burglar-proof door (1) according to the present invention into the open position, it is necessary to insert the corresponding key (not shown) into the keyhole (23) of the padlock (12) shown in Figs. 2-4 through the corresponding hole (5) and rotate it in the lock (12) accordingly to actuate the rod (17, 18). The rod (17, 18) moves in one of the above directions to move the valve (15, 16). After unlocking the padlock (12) and moving the valve (15, 16), so that access to the mortise lock (10, 11) is provided, the user inserts a corresponding key (not shown) in the hole (3, 4) to unlock the mortise the lock (10, 11) by turning the key accordingly in the corresponding keyhole (21, 22) of the lock (10, 11).

In this case, the crossbar (19, 20) of the mortise lock (11, 12) goes out of interaction with a blind hole (24, 25) located in the second door leaf so that the crossbar (19, 20) comes out of the through hole of the connecting plate (13 , 14), and it can be removed from the hole for the plate (not shown) to disconnect the first door leaf (9) from the second door leaf (8).

Thus, access to the room, the doorway of which is closed by a burglar-proof door (1) according to the present invention, can be made after unlocking all the locks contained in the specified door (1), and then by sequentially opening the first (9) and second (8) door leafs in opposite directions, shown in figure 2 by dashed and solid lines.

It should be noted that the described device is only one of the preferred embodiments of the invention. For a person skilled in the art it is obvious that changes and modifications can be made to the present invention without deviating from the scope of the invention defined by the claims described below.
