Description

The invention relates to a lock for an opening part of a vehicle.

Such a lock, described in document EP 1030014, will hold the bracket holding tongue, which is acted upon by a return spring mounted on the pivot axis of the tongue, with one end of this spring resting on the supporting surface of the tongue and the other end of the spring entering the fixed part of the lock. This torsion or compression spring provides an automatic return of the tongue to the fully open position, and it closes with overcoming the force of this spring due to the pushing force of the bracket on one of the lever arms, for example, when the opening part is slammed shut.

In the process of manufacturing the lock, the part, which includes the spring, must be stored in a warehouse and installed during the manufacture of the lock, which leads to increased costs for logistics and manufacturing.

In addition, the installation of this spring is relatively difficult, and during installation, the spring can be forgotten.

Finally, this spring-return design is characterized by relatively high energy upon impact, resulting in a relatively loud knock.

The objective of the invention is to eliminate the above drawbacks by creating a lock for a vehicle, ensuring the return of the tongue and its retention in the open position without the use of special installable parts and with a decrease in the volume of knocking.

In this regard, the object of the invention is a lock for the opening part of the vehicle, comprising a bracket retaining tongue in the housing that is rotatable about an axis and on which a return element to a fully open position acts, wherein said tongue and said bracket are arranged in such a way that the bracket pulls on the shoulder of the lever of the tongue to the intermediate opening position during opening, according to the invention, said element for returning to the fully open position is made as another element containing the protrusion, made in such a way that the support force on this protrusion is displaced relative to the indicated rotary axis of the tongue and leads to the return of the tongue to a fully open position, while the specified intermediate opening position corresponds to the transition through the specified protrusion until the moment when the protrusion can create the moment the tongue turns into its fully open position.

The invention may additionally contain one or more of the following distinctive features, taken separately or in combination:

- the return element is located on a part of the housing and interacts with the element made on the tongue;

- the return element is made in part of the housing by molding and interacts with the element made on the tongue;

- the interacting element is made on the tongue by means of an additional

casting;

- the interacting element is made integral with the tongue;

- the return element also interacts with the buffer of the tongue located on the part of the housing;

- the return element is made on the tongue by means of additional casting.

various embodiments of the invention.

As shown in figure 1, the lock for the opening part of the vehicle in accordance with the invention contains in the housing a tab 1 holding the bracket 2, made with the possibility of rotation around axis 3, while the tongue acts element 4 return to the fully open position.

In the closing position, the tongue is locked by the dog 5, abutting against the shoulder of the lever or tooth 1A of the tongue.

As is known, during opening after the release of the dog 5, the tongue 1 and the bracket 2 are arranged and made in such a way that the bracket 2 pulls the second shoulder 1B of the tongue and rotates this tongue to the intermediate opening position corresponding to the loss of contact with the bracket and shown in FIG. 2 during opening.

Next, the return element 4 moves the tab 1 and then holds it in the fully open position shown in FIG.

According to a non-limiting embodiment of the invention, this return element 4 is an elastic element integrated in a part 6 of the housing of plastic material near the tongue, and interacts with the interacting element 1C made on the tongue.

In another embodiment, the return element can be made in the form of any elastic element embedded in the fixed element of the lock near the tongue.

Preferably, the return member 4 is formed in the housing part 6 by casting.

Preferably, the interacting element 1C is made on the tongue by means of additional casting.

In particular, as shown in figure 4, the return element 4 is an elastic plate containing a protrusion 4A and made in the cavity of the housing part 6, located in a plane parallel to the front surface of the tongue 1. Preferably, this protrusion has a rounded shape in the form of a semicircle on the plate four.

The interacting element 1C is located on the tongue and is made, although this option is not limiting, in the form of a pin extending in a plane perpendicular to the front surface of the tongue 1. This interacting element is located on the front surface of the second shoulder 1B of the tongue lever and extends between the wall of the cavity part 6 body and plate 4 from the side of the protrusion 4A. The protrusion 4A is directed towards the rotary axis 3 of the tongue 1 and is designed so that the support force of the interacting element 1C on this protrusion is displaced below the rotary axis 3 of the tongue in the intermediate opening position shown in FIG. 2 to create a moment of rotation in the fully open position, shown in figure 3.

In this position, the plate 4, previously prestressed during the previous movement of the interacting element, acts on this protrusion by the force pushing the second lever arm 1B, turning the tab to the fully open position shown in FIG. 3, in which the interacting element 1C is held in the lower part of the plate 4 in the fully open position due to the fact that the interacting element 1C remains under the action of pressure from the plate 4 in the fully open position.

Further closure of the lock occurs classically due to the pushing force of the bracket on the first shoulder 1A of the tongue lever and the lifting of the interacting element 1C above the protrusion 4A towards the upper part of the plate 4, as shown in figure 1.

In the first embodiment of the invention, shown in Fig. 5, the interacting element 1C made on the tongue 1 is located on the front surface of the first shoulder 1A of the tongue lever, while the elastic plate 4 is made in the corresponding cavity of the housing part 6 located in a plane parallel to the front surface tongue 1.

In the second embodiment of the invention, shown in Fig.6, the interacting element 1C is made on the toe of the tongue 1 opposite the shoulders 1A and 1B of the lever, while the elastic plate 4 is made in the corresponding cavity of the housing part 6 located in a plane parallel to the frontal surface of the tongue 1.

In the third embodiment of the invention shown in FIG. 7, the lock also comprises a tongue buffer 7. In this case, we are talking about the usual elastically deformable element used to dampen the movements of the tongue 1. In the framework of the invention, the elastic plate 4 is placed opposite the buffer of the tongue. Thus, the interacting element 1C in the form of a toe, located on the back of the tongue 1, pushes the plate 4, which, in turn, compresses the buffer 7 of the tongue. In addition, by placing the recess 8 on the buffer of the tongue, you can better control the force. As soon as the toe of the tongue 1 passes through the protrusion 4A of the plate 4, the buffer 1 of the tongue restores energy by repelling the plate 4 and creates a turning moment on the tongue 1. Thus, the buffer 7 of the tongue ensures the stability of the function in time, and at any temperature.
