Description

The utility model relates to construction, namely, locking devices for window frames, balcony and terrace doors and is designed to prevent unauthorized entry into the room through windows, windows, balcony and terrace doors that open inside.

The following structures of locking devices are known from the prior art.

So, from the description of the patent of the Russian Federation No. 2344262 (published on January 20, 2009), a window protection device with at least one opening sash against unauthorized entry is known that contains a grating with a hinged section and with a locking mechanism designed to be fixed from the outside of the window so that the hinged section of the grill was located opposite the opening sash of the window. The locking mechanism is made in the form of eyes located parallel to the plane of the grating, one of which is fixed to the swinging section of the grate, and designed to accommodate a curved bucket-shaped rod in the holes of the eyes, so that the curved part covers the upper part of the eyes. The rod is made with a handle.

It is also known a device for protection against burglary, which contains at least on the peripheral surface of the cutout of adjacent runs in the stepped profile groove of the pusher fittings, the hardware consists of a covering guide of the pusher. The pusher moves along the bottom, the device also contains a locking element, moved by the pusher of the pusher accessories, installed and released from the locking mesh by the elements of the locking mesh, while the meshing elements are located on the covering guide of the other pusher accessories and have a locking device, the locking device blocks the movement of the pusher closed fixed leaf due to the interaction of the safety part located on this pusher with the locking m element placed on the pusher of other accessories of the pusher, and the safety part in the closed position is completely blocked by the locking engagement (RF patent No. 2314399, published 01.10.2008).

Also known is a device for protection against opening windows by children and unauthorized entry. Contains a base and a latch made with the possibility of rotation about the axis of symmetry of the base. A lock is also integrated in the device (German patent No. 29804813, published May 28, 1998).

All of the above devices, in contrast to the claimed locking device, are locks and require the installation of the counterpart and the internal lock in the handle.

The closest analogue to the patented solution is "Turntable" (RF patent No. 112246, published January 10, 2012), which is a latch that is movably fixed to the base, while the latch is rotatable.

The known device is designed to prevent accidental opening of a door or gate from any external factors, for example, wind or animal actions, however, it will not be able to protect it from breaking by force acting on the door / window from the outside, since it contains only one latch and is made of insufficiently strong polymer material.

The technical problem to which the claimed utility model is aimed is to create a durable and reliable locking device that protects against force breaking outside, does not require the installation of an additional counterpart and internal lock in the handle, and which can be installed on single frames, and can also be installed on windows and doors from any material (plastic, wood).

The technical result of the claimed technical solution is to increase the reliability of the locking device and resistance to burglary during power opening from the outside due to double emphasis during power opening from the outside and the material used.

The claimed technical result is achieved due to the design of the locking device, which is a steel structure consisting of two L-shaped clamps, movably mounted on one base, while the clamps are made with the possibility of rotation towards each other.

Thus, due to the use of two L-shaped clamps made of durable material (steel), a double stop is created when power is opened from the outside, and the reliability of the locking device is ensured.

Further, the solution is illustrated by reference to the figures, which show the following:

FIG. 1 is a front view of a locking device.

FIG. 2 is a side elevational view of the locking device.

FIG. 3 is a top view of the locking device.

FIG. 4 is a front view of the latch.

FIG. 5 is a general view of the latch on the side.

FIG. 6 is a general view of the latch from above.

FIG. 7 is a general view of the base from above.

FIG. 8 is a side elevational view of the base.

Steel latches (4) are movably attached to the steel base (1) of the device using self-tapping screws (4) with washers (3) made of polyethylene terephthalate, which provide sliding when the latches are rotated relative to the common base, and countersunk heads closed with decorative caps (5).

The device operates as follows. Using two self-tapping screws (4) and holes made in the base (1), the device is attached from the inside of the room to the frame of the window frame next to the opening leaf opening inward, or to the door jamb next to the door leaf opening inward.

In the idle state, the clamp handles (2) are parallel to the surface of the opening window sash and do not interfere with the opening of the window sash.

To prevent opening from the outside of the window, the clamp handles (2) are brought into a perpendicular position relative to the surface of the opening window sash by turning them towards each other, so that the clamp handles (2) cover part of the sash, thereby locking the sash and preventing opening from the outside. To make it inoperative, the latches (2) rotate in opposite directions.

Depending on the size of the frame and the desire of the consumer, 1-2 or more locking devices for one openable sash are installed. Installation of four locking devices: two at the top and bottom of the leaf edges - creates resistance to breaking up to 1.8 tons.

This design is not a lock, does not require the installation of an additional counterpart and an internal lock in the handle, can be installed on single frames, and can also be installed on windows and doors made of any material (plastic, wood).

The presented design is a mechanical locking device that creates resistance to breaking due to the material (steel) and two parallel L-shaped clamps (2). The device does not weigh down and does not increase the price of the entire window frame. It can be installed anywhere and in the required quantity. It is an inexpensive and affordable mechanical protective tool, unlike window locks.

The device can be used on all types of frames (plastic, wooden), to protect against the penetration of all types of premises (residential, industrial, warehouse, etc.)

Claims (2)

1. The locking device to prevent unauthorized entry into the room, characterized in that it is a steel structure consisting of two L-shaped latches, movably mounted on one base, while the latches are made with the possibility of rotation towards each other. 2. The locking device according to claim 1, characterized in that the latches are movably attached to the base of the device using self-tapping screws with countersunk heads and washers.
