Description

LOCKING DEVICE

FIELD OF TECHNOLOGY RELATED TO

INVENTION

The invention relates to the field of devices that complicate or prevent the unauthorized opening of shutters equipped with locking elements (windows, doors, cabinets, safes or first-aid kits), for example, by children or pets.

BACKGROUND

Known lock elements intended for fastening to swing leaves of windows and / or doors, mainly to protect against unauthorized opening by children, animals, legally incapable persons or legally incapable persons, when opening the shutters without permission is undesirable (for example, doors and hatches in public transport, clinics, public places). Such locking elements usually consist of a housing with fastening elements to the sash, a counterpart which is mounted in the window or door span area, a two-position clutch element (bolt, hook, curly plate), which is adapted to engage with the counterpart in the closed position and trip in position

“Open” and an access control element connected to the clutch element. The access control element is any known mechanism that provides the translation of the clutch element from the "closed" to the "open" position using a key. Preferably, when the access control element is designed so that it cannot be moved from the "closed" position to the "open" position with bare hands and / or without a key. If the access control element contains a secret mechanism, it can be a key with a unique pattern of grooves / grooves / recesses corresponding to a unique secret mechanism. However, it is possible that the access control elements are designed to open with a screwdriver, coin, a metal polyhedron, a magnetic key, applying an electrical voltage to the contacts, dialing a code, etc. In this case, a key is understood to mean any element that the user (unlike other persons) knows that it can be used to activate an access control element, or (unlike other persons) has a key and / or special skills necessary to activate an access control element with its help. One of the known locking elements of this type is the Baby Safe Lock, shown in action in the video review.

https://www.voutube.com/watch?v=tBTgNuJn9as.

A disadvantage of the known locks that impede the achievement of the following technical result is that the access control elements are subject to damage. For example, children can spoil the secret mechanism in the larva with chewing gum, stylus, small debris, as well as glue, scissors, a screwdriver, etc. At the same time, the child’s spoiling of the secret mechanism may not be outwardly visible, and the user may not be aware that the lock does not function to open, which is especially dangerous in emergency situations (fire) when the lock is in the “closed” position and blocks the possibility of opening the window / doors, even if the user has the key.

Another disadvantage is low security, since in the case of

critical situation (smoke, fire) to open the sash, you must find the key, which may be lost or may be in another, unsafe room.

In accordance with the present invention, it is proposed to provide locking of a casement window, cabinets, cabinets, first-aid kits, etc., as well as doors from unauthorized opening by children or animals, using a device that does not require a key.

Opening is ensured by mechanical action on the lid, followed by rotation. Moreover, only rotation of the cover is not enough to translate the proposed device into the "open" position. This requires action going contrary to the usual and, as a rule, already developed in the child's skill in unscrewing, for example, covers. Similar solutions are known in the field of packaging (see, for example, the following patent documents for covers: US3435975, DE2927399A1, EP0026284A1, FR2403274A1, US12481931, US20020027120A1, US20030121877A1, US20050161425A1, US20060057257A1011011016011016011016

In particular, packages are known having a threaded neck and a cap, in which there is a sleeve between the cap and the thread that is screwed onto the thread. In this case, in the normal state, the cover is essentially free or with insignificant resistance (the moment of rotation transmitted from the cover to the sleeve below the sleeve's breaking limit) rotates relative to the sleeve, and the clutch between the cover and the sleeve sufficient to move the sleeve and unscrew is provided only under additional conditions, for example, when pressing on the upper and / or lateral end face of the cover.

However, to block (lock) the shutters of windows, doors, cabinets, cabinets, safes or first-aid kits and protect them from unauthorized opening, for example, by children or pets, such solutions were not used in locking devices.

SUMMARY OF THE INVENTION

Unless the context otherwise indicates, the terms and expressions used in this text should be given the following meaning: “Axis” (and the corresponding derivatives of this term) is a line that, in the closed position of the leaf, at least at the initial moment, coincides with the direction of movement of the leaf zone located in the immediate vicinity of the lock element when it is opened. For hinged and hinged flaps, the “axis” and “axial direction” are essentially perpendicular to the span plane, for sliding flaps it coincides with the direction of sliding.

"Transverse direction" is a direction substantially perpendicular to the axial direction.

By “pushing” is meant the application of force to the cap along the axis to bring it into translational motion to the sleeve. When pressed, the spring elements between the cover and the sleeve are compressed.

By "squeezing" is meant the application of force to the cover in the direction from the side to the axis so that the cover is deformed and its side parts bend in the direction of the axis.

Other terms and expressions should be interpreted in accordance with their usual meaning with due regard to the context and visual aids, avoiding the contradiction of the concept of the present invention, its specific examples, and common sense.

An object of the present invention is to provide a device for protecting a locking element having a combination of the following advantages:

1) the ability to open without a key;

2) preventing or at least reducing the likelihood of opening at least one leaf by a child or animal;

4) the absence in the device of unprotected elements that are easily spoiled by the child;

5) the possibility of external masking of the blocking device from the child’s extra attention;

The technical result provided by using the invention consists of:

1) to expand the arsenal of tools that impede or at least reducing the likelihood of the sash opening by the child, and without requiring the use of a key.

DETAILED DESCRIPTION OF THE INVENTION

As shown in FIG. 1-5, as well as in FIG. 7, 8 or 9, the locking device of the sash, contains:

case equipped with fasteners,

locking elements including a locking element and a response element, made in such a way that when the said locking element is in the "open" position, the locking element moves freely relative to the said response element when the said sash is opened, and in the "closed" position the response element prevents the movement of the locking element relative to the said response element when opening the said leaf, the sleeve mounted on the said housing with the possibility of rotation, and kinematically connected with the said locking element with the possibility of converting the rotational movement so as to translate the said locking element from the "open" position to " closed "and vice versa

a cover mounted on said sleeve and configured to prevent access to the surface of said sleeve.

Said cover of the locking device is rotatably mounted on said sleeve so that, in the absence of pressing and / or squeezing, said cover is able to freely rotate in the “open” direction relative to said sleeve, which remains stationary, while said sleeve and cover are provided with clutch elements configured to block said rotation by pressing and / or squeezing, so that said cover and sleeve are able to rotate simultaneously with each other in the “open” direction. In FIG. 7, 8 and 9 show variants of the device in which the clutch means are triggered when pressed, when squeezed and while pressed and

squeezing, respectively.

The device is attached to the opening and frame, as shown in FIG. 1 and 2 by means of fasteners.

To open the sash with the embodiment of the device shown in FIG. 7, the user must first press on the cover, compressing the spring elements, and only if the pressure is sufficient, the protrusions and grooves of the cover and sleeve enter each other, allowing the transmission of torque from the cover to the sleeve, after which the user can unscrew cover from the housing together with the sleeve, open the access control and use the key. If an unauthorized user tries to unscrew the cover without pressing it, it will freely rotate relative to the sleeve without separation from the case, thus an unauthorized user will not be able to open access control means.

Similar actions need to be taken with the device options depicted in FIG. 8 and 9: in the case of the device of Fig. 8, instead of pressure, it is necessary to compress the cover for the clutch elements to act, and in the case of the device 9, simultaneously press the cover and squeeze (deform) to activate the clutch elements.

The design of the device provides effective protection against children and at the same time does not require the use of a key, which is why it is safer in comparison with known devices.
