Description

Application area

The invention relates to window fittings, in particular to devices for blocking the possibility of opening a window sash while maintaining its inclination in the airing position of the room, and is intended to be protected against opening by children, for their safety, and also against penetration from the outside (IPC index (2016.01) Е05В 1 / 00).

State of the art

Child safety in the operation of windows of a modern design is an important public problem. The use of mosquito nets in order to protect the child is completely unacceptable, since the fasteners and the net itself are not designed for the weight of the child. The use of window handles with a locking mechanism is only possible for protection against children in the closed position, which makes it impossible to protect the child while ventilating the room. Therefore, there is a public need to create reliable locks-locks for windows that will ensure the safety of children and the preservation of the possibility of airing the room.

The closest analogue in technical essence is the safety latch [TR, 2014-G-90367, E05B1 / 00 of 01/21/2015], which includes a movable lever, the cylindrical part of which enters the hole in the housing, and a cover. Locking the position of the lever is provided by a latch with a spring and a push-button mechanism. Additional protection against children opening the window is provided by a locking mechanism, including a cylindrical element of complex design, a spring and a key.

The disadvantage of the closest analogue is the complex design and insufficient reliability of operation, due to the presence of a separate button mechanism, which often interlocks when interacting with the latch, which makes operation not convenient enough. In addition, it is impossible to use the described safety latch with various types and designs of windows, due to the unintended adjustment of the gap between the window sash and the movable lever.

Technical challenge

The basis of the invention is the following technical task: simplifying the design of the lock-lock for windows, increasing the reliability and ease of operation, ensuring versatility when used with various types and designs of windows, while maintaining high efficiency of protection against children opening from the inside and entering the room from the outside, and also the possibility of translating and operating the window in the ventilation position of the room.

Disclosure of invention

The solution to the technical problem is provided by the fact that the lock-lock for windows contains a movable lever, consisting of a locking part and a cylindrical part on which grooves are radially placed. The cylindrical part of the movable lever enters the lever hole of the housing and is fixed in it with a washer, which is installed in a circular groove. The push-button hole with the neck of the housing includes a locking mechanism, including: a control button on which a travel stop is made, a circular groove for fixing in the housing with a locking ring and a transverse groove for fixing with the boss of the lower insert. The lower insert enters the control button and contains grooves for installing the key, as well as a figured protrusion for interacting with the latch. The latch is mounted on the lodgements of the cover and has an inclined cutout for interacting with the figured protrusion of the lower insert. A vertical spring for preloading the locking mechanism is installed between the lug protrusion and the lower insert, and a horizontal retainer spring is installed on the lid protrusion, to automatically fix the position of the movable lever. When changing the position of the movable lever, its grooves engage with a rectangular cutout of the latch. The lock-lock is fixed on the window frame using fasteners included in the mounting holes of the housing and the cover and are closed with cylindrical caps with an upper base truncated at an angle. A blind hole is made at the end of the locking part of the movable arm for mounting pads with a hole in the center for sequentially fixing several substrates, which can be of different thicknesses.

It is possible to use a cylinder mechanism with a movable button function as a locking mechanism, which includes a figured protrusion for interacting with an inclined cutout of the lock and two pairs of protrusions, the first pair of protrusions limits the axial movement of the cylinder mechanism when pressed in case the lock is released, and the second pair protrusions provides blocking the movement of the cylinder mechanism, when it is rotated 90 degrees, and entering the gap between the protrusions of the protrusion of the housing, which de AET impossible to unlock the latch by axial movement of the cylinder mechanism, a cylinder mechanism is formed inside a shaped cutout for the secret key with which the rotation cylinder mechanism occurs.

The implementation of the invention

The lock-lock for windows contains a movable lever (1), consisting of a locking part (2) and a cylindrical part (3), on which grooves (4) are radially placed. The cylindrical part (3) of the movable lever (1) enters the lever hole (5) of the housing (6) and is fixed in it with the washer (7), which is installed in a circular groove (8). The push-button hole with the neck (9) of the housing (6) includes a locking mechanism (10), including a control button (11), on which are made: a travel stop (12), a circular groove (13) for fixing in the housing (6) with a locking ring (14) and a transverse groove (15) for fixing the lower insert (17) with the boss (16). The lower insert (17) enters the control button (11) and contains grooves (18) for installing the key (19), a figured protrusion (20) for interacting with the lock (21). The latch (21) is mounted on the lodgements (22) of the cover (23) and has an inclined cut-out (24) for interacting with the figured protrusion (20) of the lower insert (17), and a vertical spring (25) for preloading the locking mechanism (10) is installed between the protrusion of the cover (26) and the lower insert (17). The horizontal spring (27) of the latch (21) is mounted on the protrusion (28) of the cover (23), to automatically fix the position of the movable lever (1). When changing the position of the movable lever (1), its grooves (4) engage with a rectangular cut-out (29) of the lock (21). The lock-lock is fixed on the window frame (not shown in the drawings) with the help of fasteners included in the mounting holes (30) of the housing (6) and cover (23) and are closed by 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 arm (1), a blind hole (32) is made for mounting pads (33) with a hole (34) in the center for sequentially fixing several substrates that may have different thicknesses.

It is possible to use as a locking mechanism (10) a cylinder mechanism (35) with the function of a movable button, which includes a figured protrusion (36) for interacting with an inclined cutout of the lock (24) and two pairs of protrusions, the first pair of protrusions (37) limits the axial the movement of the cylinder mechanism (35) when pressed in the case of unlocking the latch (21), and the second pair of protrusions (38) blocks the movement of the cylinder mechanism (35), when it is rotated 90 degrees, and entering the gap between the protrusions (3 8) the protrusion of the housing (39), which makes it impossible to unlock the latch by axial movement of the cylinder mechanism (35), and inside the cylinder mechanism (35), a shaped cutout (40) for the secret key (41) is made, with the help of which the cylinder mechanism rotates.

Lock-lock for windows works as follows.

In the closed position, the locking part of the movable arm is perpendicular to the housing and is fixed by a latch, in the rectangular cutout of which there are grooves and the main surface of the cylindrical part of the movable arm. When the control button of the locking mechanism is pressed, the vertical spring is compressed and the lower insert is axially moved, which interacts with the inclined cutout of the latch through the curved protrusion and forces the latter to shift, compressing the horizontal spring and releasing the movable lever. The movable lever is moved to the open position, that is, the locking part occupies a position parallel to the housing, and the button is released and, under the action of a vertical spring, takes its initial position, while the latch under the action of a horizontal spring occupies a position for automatically locking the movable lever when it is moved to the closed position. The described technical solution for the interaction of the locking mechanism and the latch provides reliable and convenient operation, and also simplifies the design by eliminating the intermediate push-button mechanism, which is the cause of frequent jamming.

For additional protection against children opening the window, for the sake of their safety, the use of a key is provided, which ensures the locking of the locking mechanism and, as a result, the movable lever in the closed position. To do this, the key passes through the through hole of the control button and engages through the grooves with the bottom insert. Under the action of the key (turn right or left 180 °), a horizontal spring is compressed, the curved protrusion of the lower insert disengages from the button, and the lower insert rotates 180 °. In this position of the lower insert, pressing the button does not unlock the movable lever, since the curved protrusion of the lower insert does not interact with the inclined cutout of the latch and does not cause the latter to shift when the button is pressed.

When using the cylinder mechanism as the locking mechanism, the operation of the lock-lock mechanism is similar, but has the following features. The first pair of protrusions of the cylinder mechanism limits its axial movement when it is pressed in case the lock is released, and the second pair of protrusions blocks the movement of the cylinder mechanism when it is rotated 90 degrees and the gap between the protrusions of the protrusion of the housing is blocked, which makes it impossible to unlock the lock by axial movement of the cylinder mechanism. The rotation of the cylinder mechanism occurs using a secret key.

The lock-lock for windows is mounted on the window frame using fasteners included in the mounting holes of the case and cover. To provide an aesthetic function, caps are provided in the form of cylinders with an angle-truncated base. To ensure the use of the claimed device with various types and designs of windows, it is possible to install linings with a hole in the center for sequential fixing of several substrates, which may have different thicknesses. This eliminates runout and damage to the surface of the casement windows and increases the reliability of the device.
