Description

Application area

The invention relates to window or door hardware, is intended to limit the free opening of a window / door to a safe distance determined by the length of the cable, while maintaining the tilt of the window sash in the airing position of the room and providing effective protection against opening the window / door by children for their safety, as well as from penetration into the room from the outside (IPC index (2016.01) Е05В 63/00; Е05В 65/00; Е05В 13/00).

State of the art

Limiters for opening windows and doors with a cable or other types of connecting parts between fasteners on the sash and frame are known in the market and have established themselves as an effective device to protect the premises from outside penetration. Less common are devices with a locking mechanism to protect children from opening windows from the inside, for their safety. The designs of such devices do not provide adequate reliability and ease of use. Therefore, there is a public need for the development of a simple, reliable and easy-to-operate cable lock.

The closest analogue in technical essence is a cable limiter for locking windows and doors [WO / 2014/108680, E05B65 / 00; E05B13 / 00; E05B17 / 36, dated July 17, 2014], which consists of two parts, the first of which contains a housing with a locking mechanism and a hole for the rod and is mounted on the window sash, and the second part contains a fastener, cable and rod for fixing on the frame window. The locking mechanism includes a cylindrical part, a latch and a spring, which ensure the fixation of the rod in the opening by turning the key.

The disadvantages of the closest analogue are its complex design and insufficiently convenient and reliable operation, due to the presence of a large number of assembly units and the lack of the ability to change the position of the stem without the mandatory use of a key.

Technical challenge

The basis of the invention is the following technical task: simplifying the design of the lock-limiter opening with a cable, improving reliability and ease of use, while maintaining high efficiency of protection against children opening from the inside and entering the room from the outside, as well as the possibility of transferring and operating the window in the airing position of the room.

Disclosure of invention

The solution to the technical problem lies in the fact that the lock-limiter for opening with a cable contains the main unit with a locking mechanism, which is mounted at the bottom of the movable window sash, as well as an additional unit in the form of a metal holder with a fixed end of a steel multi-core cable in a plastic casing, which is mounted on the window frame. In this case, a rod containing a tip with a cable holder and a cylindrical surface with a circular groove enters the rod hole of the main unit body. The push-button hole with the neck of the main unit body includes a locking mechanism, including a control button on which a travel stop is made, a circular groove for fixing in the case with a locking ring and a transverse groove for fixing with the boss of the lower insert. The bottom insert enters the control button and contains grooves for the key to enter, a curly 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 stem position. In this case, the radial recess of the retainer enters the circular groove of the rod and fixes it. The main unit with a locking mechanism is mounted using fasteners included in the mounting holes of the housing and the cover and closed with cylindrical caps with a truncated upper base at an angle. The additional unit is attached to the window frame using fasteners that fit into the mounting holes and are closed with cylindrical caps with an upper base truncated at an angle.

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

The implementation of the invention

The lock-limiter for opening with a cable contains the main unit (1) with a locking mechanism (2), which is attached to the bottom of the movable window sash (not shown in the drawings), as well as an additional unit (3) in the form of a metal holder (4) with a fixed the end of a steel multi-core cable (5) in a plastic casing mounted on a window frame (not shown in the drawings). At the same time, a rod (8), which contains a tip (9) with a cable holder (5), a cylindrical surface (10) with a circular groove (11), enters the rod hole (6) of the body (7) of the main unit (1). The push-button hole with the neck (12) of the body (7) of the main unit (1) includes a locking mechanism (2), which includes a control button (13), on which a travel stop (14), a circular groove (15) for fixing in the body (7) a retaining ring (16) and a transverse groove (17) for fixing with the boss (18) of the lower insert (19). The lower insert (19) enters the control button (13) and contains grooves (20) for the key to enter (21), a figured protrusion (22) for interacting with the lock (23). The latch (23) is mounted on the lodgements (24) of the cover (25) and has an inclined cutout (26) for interacting with the figured protrusion (22) of the lower insert (19). A vertical spring (27) for preloading the locking mechanism (2) is installed between the protrusion (28) of the cover (25) and the lower insert (19), and a horizontal spring (29) of the lock (23) is installed on the protrusion (30) of the cover (25) to automatically lock the position of the stem. In this case, the radial recess (31) of the retainer (23) enters the circular groove (11) of the rod (8) and fixes it. The main unit (1) with the locking mechanism (2) is mounted using fasteners (not shown in the drawings) included in the mounting holes (32) of the body (7) of the main unit (1) and the cover (26) and are closed with caps (33) cylindrical with a truncated at an angle upper base. The additional unit is attached to the window frame (not shown in the drawing) using fasteners (not shown in the drawing), which enter the mounting holes (34), are closed by caps (33) of a cylindrical shape with an upper base truncated at an angle.

It is possible to use as a locking mechanism (2) a cylinder mechanism (35) with the function of a movable button, including a figured protrusion (36) for interacting with an inclined cutout (26) of the clamp (23) and two pairs of protrusions, the first pair of protrusions (37) limits the axial movement of the cylinder mechanism (35) when it is pressed in case the lock (23) is unlocked, and the second pair of protrusions (38) locks the movement of the cylinder mechanism (35) when it is rotated 90 degrees, and enters the gap between the protrusions ( 38) UPA of the housing (39), which makes it impossible to unlock the latch (23) by axial movement of the cylinder mechanism (35), and inside the cylinder mechanism (35), a curved cutout (40) for the secret key (41) is made, with the help of which the cylinder mechanism rotates .

The lock-limiter opening with a cable works as follows.

When the rod is installed in the rod hole, the clamp moves longitudinally until it is ready for automatic operation. Upon further entry of the rod, in the rod hole, the radial recess of the latch enters the annular groove of the rod and the latch automatically locks.

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 stem. In this case, the rod must be pulled out of the rod hole to remove the restriction in order to open the window. Next, the button is released and under the action of a vertical spring takes its initial position, and the latch under the action of a horizontal spring takes its extreme position. The described technical solution for the interaction of the locking mechanism and the latch provides reliable and convenient operation, with the possibility of changing the position of the stem without the mandatory use of a key.

For additional protection against opening the window for children, 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 rod 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 stem, 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 a 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 the case of unlocking the latch, and the second pair of protrusions blocks the movement of the cylinder mechanism when it is rotated 90 degrees and the gap between the second pair of protrusions of the protrusion of the housing makes it impossible to unlock retainer by axial movement of the cylinder mechanism. The rotation of the cylinder mechanism occurs using a secret key.

The main unit is mounted using fasteners, which enter the mounting holes of the main unit body and cover and are closed with cylindrical caps with an upper base truncated at an angle. The additional unit is attached to the window frame using fasteners included in the mounting holes and are also closed with cylindrical caps with an upper base truncated at an angle. The installation of caps in the form of cylinders with an upper base truncated at an angle ensures an aesthetic function.
