Description

Field of technology

The invention relates to construction, in particular to window fittings, namely devices that block the possibility of opening a window sash while maintaining its tilt and the position of ventilation of the room and is intended to protect children from opening the window and for their safety, as well as to protect the room from penetration from the outside (MIK index (2020.03) E05С 17/50).

State of the art

The problem of ensuring child safety in the case of using plastic windows is quite acute. The main risks for a child associated with using a window are the risk of falling out of the window or injury from a suddenly opened window that was closed by a draft. Trying to protect a child by using mosquito nets is absolutely unacceptable, since the net is not designed to support the weight of a child. The use of conventional window locks does not provide complete safety when ventilating the room.

Only a comprehensive implementation of protection can ensure the proper degree of security, because concentrating on some risks, it is easy to lose sight of others. Considering the above, there is a need to create reliable window locks that will ensure the safety of children and maintain the possibility of ventilating the room.

A tilt-and-turn window with an opening limiter is known, including a fixed frame with or without imposts, with one or more rotary, tilt-and-turn sashes installed in the frame, and an opening limiter, in which the opening limiter consists of a rod and a strip mounted on the frame (impost). , in the longitudinal slot of which one end of the rod is hinged with the possibility of movement along it, the other end of which is equipped with a lock and is hinged with the possibility of detachable connection at the end of the sash (Patent No. RU148714, Publ. 12/10/2014).

However, the known solution is mounted with one part on the frame and the other on the sash, which leads to damage to part of the window. In addition, the opening limiter will not be in demand in the future, due to the fact that children grow up and the relevance of this invention disappears. An unpleasant aspect after using this device will be unsightly holes in the mounting points in the frame, which greatly worsen the appearance of the window.

A device for windows, which consists of a housing (6), a movable lever (1), a locking mechanism (10), a latch (20) with springs and a cover (23), characterized in that the movable lever (1), which consists of a locking part (2) and the cylindrical part (3), on which the grooves (4) are radially placed, while the cylindrical part (3) fits into the lever hole (5) of the body (6) and is fixed in it using a washer (7), installed In the circular groove (8) of the cylindrical part (3) of the movable lever (1), and in the button hole with the neck (9) of the body (6) there is a locking mechanism (10), including a control button (11), on which a travel limiter is made ( 12), a circular groove (13) for fixation in the body (6) with a locking ring (14) and a transverse groove (15) for fixation with the boss (16) of the lower insert (17), which fits into the control button (11), lower insert (17) contains grooves (18) for installing the key (19), a shaped protrusion (20) for interacting with the latch (21), the latch (21) is installed on the supports (22) of the cover (23) and has an inclined cutout (24) for interaction with the shaped protrusion (20) of the lower insert (17), the vertical spring (25) of the lower insert (17) for prestressing the locking mechanism (10) is installed between the protrusion of the cover (26) and the lower insert (17), and the horizontal spring (27) The latch (21) is installed on the protrusion (28) of the cover (23), to automatically fix the position of the movable lever (1), the grooves (4) of which engage with the rectangular cutout (29) of the latch (21), the lock-lock is fixed on the frame windows using fasteners that fit into the mounting holes (30) of the body (6) and the cover (23) and are closed with caps (31) of a cylindrical shape with an upper base truncated at an angle, at the end of the locking part (2) of the movable lever (1) there is a blind hole (32) for installing pads (33) with a hole (34) in the center for sequential fixation of several pads, which can have different thicknesses. A device for windows according to claim 1, characterized in that a cylinder mechanism (35) with a movable button function can be used as a locking mechanism (10), including a shaped protrusion (36) for interacting with an inclined cutout of the latch (24), two pairs of protrusions, the first pair of protrusions (37) limits the axial movement of the cylinder mechanism (35) when pressed in case of unlocking the latch, and the second pair of protrusions (38) ensures blocking of the movement of the cylinder mechanism when it is rotated 90 degrees and enters the gap between the protrusions ( 38) protrusion of the body (39), which makes it impossible to unlock the latch by axial movement of the cylinder mechanism (35), and inside the cylinder mechanism (35) there is a shaped cutout (40) for the secret key (41), with the help of which the cylinder mechanism rotates ( Patent No. RU 2 695 142 C1, Published 07/22/2019).

However, the device is complex in design both for installation and use. In addition, the opening limiter will not be in demand in the future, due to the fact that children grow up and the relevance of this invention disappears. After you stop using the device, holes will remain on the window, spoiling the appearance of the window. The design of the device involves the use of a key, which in practice is often lost, which makes it impossible to open the window.

Disclosure of the invention.

The invention is based on the following technical objectives:

- increasing the degree of protection for children from opening the window by completely blocking the movement of the fittings mechanism to the position at which the window opens;

- simplification of installation of the blocker on the window, fastening it directly to the fittings;

- increasing the reliability and ease of use, while maintaining the aesthetic appearance of the window.

The technical result consists in simplifying the fastening method and ease of use, while maintaining the reliability of the design and visual features of the window.

The declared technical result is achieved by the fact that the locking mechanism of the child lock for windows, when moving the mechanism handle to the “locked” position, completely blocks the movement of the fittings to the open position.

Implementation of the invention.

A children's window lock contains a rectangular-shaped body (1) with rounded edges, in which there is a release for the lock (3) installed in the form of a curved rectangular plate with rounded edges, having a curved tongue (5) at the end. Also, the housing (1) has a hole into which a fastening sleeve (4) is installed, rigidly fixed on the back side of the housing (1) by flaring the protruding material. Before installing the mounting sleeve (4), a movable lever (2) is installed on it, which rotates around the mounting sleeve (4).

A child lock for windows is installed in window fittings that work with a modified opening sequence: when the handle is turned 90 degrees, the sash tilts back, and does not open as in the classic window fittings operation scheme. The child lock for windows is positioned with the legs (6) in the groove on the fittings designed for movement of the lock (7) and is fixed to the window with a fastener through the mounting hole (8) in the fittings and the fastening sleeve (4). The ease of installation of the child window lock is ensured by the fact that it is installed in an existing mounting hole (8) in the window fittings.

The child window lock works as follows:

In the working position, the movable lever (2) is directed towards the lock (7). In this position, the protrusion (9) on the movable lever (2) presses the front part of the latch (3) and the tongue (5) is lowered into the groove on the fittings, blocking the movement of the mechanism to the position in which the window opens.

To disable the locking, the movable lever (2) must be turned in the opposite direction. When turning, the lever (2) presses the back of the latch (3) and the tongue (5) comes out of the groove in the window fittings and the fitting mechanism is unlocked.
