Description

The utility model relates to the field of construction, and specifically to doors, in particular to the device of a burglar-proof door for locking premises and protecting them from unauthorized entry.

State of the art

The present utility model is an improvement in the design of a burglar-resistant door disclosed in the invention under patent RU 2542560 C1. The burglar-resistant door according to the patent RU 2542560 C1 contains the first and second door leaves located opposite each other and opening in opposite directions and the door frame to which the first and second door leaves are attached by means of hinges, while the first door leaf contains at least one hole for the key key and a connecting plate with an opening for a crossbar, and the second door leaf, contains at least one mortise locking device with a keyhole and a deadbolt and a counter device and an opening for the connecting plate, so that when both door leaves are closed, it is possible to insert the plate into a hole for the plate and the possibility of the passage of the bolt through the hole for the bolt into the counter device, ensuring that the plate is locked into the hole for the plate. The task solved by the invention according to the patent RU 2542560 C1 is to create a reliable door, resistant to burglary by manipulating the lock, in particular by cutting it out of the door leaf.

One of the disadvantages of the burglar-resistant door device according to the patent RU 2542560 C1 is the complexity of its design, due to a large number of different reciprocating and moving elements, which reduces its reliability, and also increases the material consumption, labor intensity of manufacture, and, accordingly, the cost of the final product.

Another disadvantage of the burglar-proof door device according to the patent RU 2542560 C1 is the relatively large distance between the first and second door leaves, which is necessary to accommodate elements protruding beyond the facing planes of the first and second door leaves, such as door handles and (or) elements and mechanisms of locking devices, which in turn negatively affects the overall dimensions of the burglar-resistant door.

Another disadvantage of the burglar-resistant door device according to the patent RU 2542560 C1 is the need to make keys of non-standard length, which is due to the fact that the locking devices and locks are located in the door leaf, closed by another door leaf, while for the above reason, there is a significant distance. This drawback creates inconveniences both in connection with the transportation and storage of keys of non-standard length, as well as in connection with their manufacture.

Goals and objectives of the utility model

The purpose of the utility model is to improve the structure of a burglar-resistant door while maintaining the qualities of burglary resistance.

The objectives of this utility model are:

- reducing the number of structural elements of a burglar-resistant door, increasing reliability, reducing material consumption and labor intensity of its manufacture.

- reducing the inter-door space of the burglar-resistant door, and increasing the compactness of its design.

The indicated technical problems were solved by the following technical means:

- coupling of the first and second door leaves together is carried out by the proposed single coupling device containing two mating parts, simultaneously providing a compact and rigid coupling of the door leaves;

- individual valves designed to block access to the keyholes of each of the locks of the locking mechanism are combined into one valve with one drive.

- on the sides of the door leaves facing each other, niches for door handles are made, having an arrangement and dimensions corresponding to the location of the dimensions of the door handles of the opposite door leaf.

Disclosure of the essence of the utility model

A burglar-resistant door contains an outer door leaf and an inner door leaf, located opposite each other and fixed by means of hinges on the door frame with the possibility of opening in opposite directions, a coupling device for connecting the outer and inner door leaves together and a mortise locking device, while the mortise locking the device is located in the inner door leaf so that the corresponding key can be inserted into the keyhole through the key hole located in the outer door leaf.

According to the present utility model, the term "external door leaf" means a door leaf located outside the protected area.

According to the present utility model, the term "inner door leaf" means a door leaf located inside the protected area.

The burglar-resistant door hitch contains positive and negative counterparts of the box-like structure, located on the facing sides of the outer and inner door leaves and made with the possibility of alignment when the outer and inner door leaves are closed, while the positive and negative counterparts contain coaxial holes for crossbars.

The locking device contains at least one mortise lock having at least one crossbar, while the mortise lock or locks are located opposite the negative part of the coupling device, with the possibility of pushing the crossbar or crossbars into the positive and negative parts aligned relative to each other through the corresponding coaxial holes for the crossbars ...

Taking into account the preservation of the burglar-resistant qualities of the burglar-resistant door, namely, by hiding the locking mechanism behind the outer door leaf, the negative part of the locking-coupling mechanism and the locking mechanism are located in the inner door leaf of the burglar-resistant door.

The total number of mortise locks of the locking mechanism in excess of one can be selected arbitrarily, taking into account the provision of the required level of burglar-resistant door resistance.

The number, shape and position of holes for crossbars, coaxially located in the positive and negative parts of the mortise locking device is determined by the configuration of the mortise locking device.

The positive and negative counterparts of the coupling device can be a continuation of the structure of the outer and inner door leaves, or they can be made by separate elements rigidly fixed to the outer and inner door leaves, taking into account the provision of the necessary strength and rigidity of the burglar-resistant door structure.

In this case, the surfaces and (or) the perimeters of the positive and (or) negative parts of the coupling device may have a damping coating, finish, or other similar means, for example, rubber gaskets, seals or restraints, shock absorbers, etc.

The ratio of the positive and negative counterparts of the coupling device is chosen so that these parts, taking into account the provision of free alignment of the counterparts when opening and closing the door leaves, are as co-operative as possible, to ensure that their relative displacement is limited, and, accordingly, the rigidity of both door leaves operating in the closed position as a single structure.

The area, depth, shape and position of the positive and negative mating parts of the coupling device relative to the outer and inner door leaves can be chosen arbitrarily, taking into account the provision of the required strength and rigidity of the burglar-resistant door structure, as well as other requirements.

The hinges of the inner and outer door leaves can be located both on one side of the door frame, providing a burglar-resistant door with a "book", or on opposite sides of the door frame. The location of the hinges affects the location of door handles and corresponding niches for handles, as well as additional locks and mechanisms, which in turn is not fundamental from the point of view of the essence of the utility model.

The external and (or) internal door leafs of a burglar-resistant door may contain additional locking devices, locks, latches, chains, latches, as well as means that ensure the convenience of using the door, for example, door peepholes.

To reduce the distance between the outer and inner door leaves in their closed position, as well as to align the positive and negative parts of the coupling device, niches for door handles are made on the facing sides of the outer and inner door leaves. In this case, the location, shape and dimensions of the niche for the door handle on each door leaf correspond to the location, shape and size of the door handle of the adjacent door leaf.

In order to block access to the keyholes of the mortise locking device, as well as to the common interdoor space of the outer and inner door leaves, the corresponding openings for key access made on the outer door leaf are made with the possibility of closing by means of a latch with a drive device. In this case, the gate valve with a drive device is placed inside the outer door leaf. A remotely controlled electro-mechanical drive or a mechanical drive containing a mortise lock kinematically connected to the valve can be used as a drive device. Depending on the device of the drive device, the bolt can move flat-parallel relative to the plane of the door leaf, or by rotation on the fastening axis. The dimensions and position of the latch for blocking access to the keyholes of the mortise locking device are determined by the location of the corresponding holes on the outer door leaf.
