BACKGROUND OF THE INVENTION

A locking mechanism [1] is known, which is housed in a housing mounted under an outer shield on the outside of a door to a standard buried lock, whose locking tongue is actuated by turning a handle or a ball. This mechanism controls the transmission of download movement to the tongue from the outside. The mechanism consists of two engagement elements rotating relative to each other, the first being individually connected to a square that passes through the lock and is connected to the inner handle, and the second engagement element is connected to a second square, which in turn is connected to the outer handle. The mechanism is engaged by actuating an electric motor that causes a worm to rotate, which in turn controls the radial movement of a pull pin located in an opening in one element by means of a pushing swing arm, to be inserted into a slot in the other element, wherein the two engagement elements become interconnected and rotate together to allow the locking tongue to be moved to its opening position.

In the radial engagement scheme selected in this decision, a radially engaging pin determines the need for the mandatory inclusion of additional details, such as a second engagement element, a second square, a swinging arm, and others mounted between the outer handle and the square transmitting the withdrawal movement to the locking mechanism. language that complicates and makes the mechanism more expensive.

The technical nature of the utility model

The object of the utility model is to create a coupling mechanism with a simplified construction and a minimum number of parts to be placed under the shields, which are mounted on a lock with a locking tongue actuated by turning handles or balls, when the mechanism is not actuated, the outer handle rotates freely without rotating the square that activates the locking tongue, and when actuated, the mechanism allows rotating the square and transmitting a pull movement to the locking tongue, as in both cases the locking tongue can be removed by means of an internal handle.

The problem is solved by a coupling mechanism coupled to door locks with a locking tongue actuated by handles or balls mounted on signage, the mechanism being placed in a box with a lid built into the outer shield and including a square passing through the locks, one end of which is permanently attached to the inner handle, as is the electric motor whose axle the worm is connected to.

According to a useful model, the mechanism further includes a profile shaped slider whose rear is permanently engaged in a profile opening of a guide sleeve secured to the cover by a spring ring, wherein the slider is coaxially disposed on the outer handle in which a profile engagement engagement is formed. with the slider, and the guide sleeve is fixed to the other end of the square so that its axis of rotation coincides with the axis of rotation of the square and the inner handle, whereby one end of the spring is engaged in the worm, and with the possibility of rotation about an axis, the other end of which extends the slider through a channel made therein, in which a section with a possibility of free rotation in the profile opening of the outer handle is formed at the front of the slider, with the slider being able to free axial movement in the profile openings of the guide sleeve and outer handle.

According to the utility model, the end of the spring that encloses the slider is shaped like a ball with the possibility of limiting the axial travel of the slider.
