Description

The invention relates to a rotary tongue for locking an opening part of a vehicle, in particular for a door of a vehicle. The invention also relates to said lock of the opening part.

Classic locks contain a housing, pad, and metal lining that define a locking compartment for locking elements such as a pivot tab and pivot dog. The lining allows you to close the housing and secure the lock on the frame of the vehicle. The tongue is designed to interact with the bracket mounted on the end of the door. The dog interacts with the tongue to fix and hold it in a position corresponding to the locking position of the lock.

Car designers require the design and manufacture of locks for opening parts in series that have identical specifications, in particular, for attachment points on the vehicle body and / or for the "point S" position (the point of intersection between the axis of the staple thread and the central plane of the tongue in the locking position of the lock) , but some of them have different specifications for the thickness of the swivel tab depending on the model of the vehicle on which the lock should be installed.

In this case, it is necessary to review the design and manufacture of locks with a tongue of smaller thickness. In particular, it is necessary to provide a new platform, a new lining and a new axis of the tongue. This design and subsequent manufacturing are relatively complex and time consuming and therefore expensive.

The objective of the invention is to eliminate the disadvantages inherent in the known technical solutions, by creating partially standard locks for several models of cars with the same position of point S, which are simple to manufacture and can reduce costs.

The problem is solved in the rotary tongue for the lock of the opening part of the vehicle, designed to interact with the bracket of the specified vehicle, while the specified rotary tab contains a metal body and has a through cylindrical hole designed to interact with the corresponding guide bearing surface of the specified lock for rotation around the axis rotation between the open position and the closed position of the lock, in which it interacts with the bracket, According to the invention, said metal body comprises compensatory thickenings protruding around said through cylindrical hole on both sides of the ends of the through cylindrical hole.

Compensation thickenings interact through the thickness of the plastic element, made by additional molding, with the corresponding guide bearing surface for guiding and centering the rotation of the tongue with good resistance to force, temperature, wear and fixing. Thus, compensatory thickenings allow you to locally expand the surface of the through cylindrical hole of the rotary tongue, interacting with the guide bearing surface, on both sides of the Central plane of the rotary tongue.

Thus, the point S remains identical for the pivoting reeds having different thicknesses. In particular, the central plane of the pivot tab remains centered with respect to the guide of the abutment surface and, therefore, to the pivot dog. In the same way, the axis of the staple thread is correctly positioned relative to the pivot tab.

Thanks to the guiding thickenings, the pivot tab can go into the compartment fixing the pivot tab of a larger thickness, without making changes to it and preserving point S. Thus, for the same body, the same lining and with the same axis reeds can use reeds of different sizes. Due to this, standardization of locks is achieved, while most of the components, with the exception of the tongue, are common to different models of vehicles. Therefore, the same assembly lines can be used.

In addition, it is possible to perform rotary tabs of smaller thickness at lower cost, using traditional cutting methods, more economical than manufacturing methods using precision cutting.

According to one or more of the hallmarks of the pivot tab, considered individually or in combination:

- these compensatory thickenings are evenly distributed in the angular direction around the specified through cylindrical holes, which allows for good retention and good positioning of the rotary tab in the corresponding guide bearing surface,

- these compensatory thickenings protrude from the rotary tongue, alternating on both sides of the indicated ends,

- the specified swivel tab contains three compensatory thickenings evenly distributed in the angular direction around the specified through cylindrical hole on both sides of these ends,

- these compensatory thickenings are performed by stamping a metal body with the formation of additional reinforcement from the side of the rotary tongue, the opposite side containing the compensatory thickening,

- the specified metal body contains made by additional molding a coating of plastic material, in particular, to reduce knocking and friction between parts that come into contact with the rotary tongue,

- compensatory thickenings are leveled due to additional casting to eliminate the discontinuity of the support of compensatory thickenings of the rotary tongue,

- performed by additional molding, the coating contains ribs on opposite sides of the indicated tongue, while the ribs allow you to compensate for the runout of the rotary tongue in the housing,

- the end of the rotary tab, designed to abut the damper of the specified lock when it is outside the closed position, contains at least one protrusion extending along the end of the tongue, to increase the contact section of the tab in the abutment position in the damper and, therefore, to improve damping distribution,

- the specified protrusion is performed by deformation of the metal body; however, the method of deformation of the material is more economical than the method of manufacture by precision cutting.

The problem is also solved in the lock for the opening part of the vehicle, comprising a housing, a platform and a metal lining defining a fixing compartment for engaging a pivot tab for engaging with a bracket, said pivot tab having a through cylindrical hole interacting with a corresponding guide bearing surface housing for rotation around the axis of rotation between the open position and the closed position of the lock in which it interacts exists with the bracket according to the invention, said lock comprises a rotary latch described above.

Other advantages and features will be more apparent from the description of the invention with reference to the accompanying drawings.

In all the drawings, identical elements are denoted by the same digital position. To simplify the drawings, they show only the elements necessary for understanding the invention.

As shown in figures 1 and 2, the lock 1 for the opening part of the vehicle, such as a door, contains a housing 2, for example, of plastic material and a lining 3, for example, of metal, covering the housing 2 and limiting the fixing compartment 4 (see partial sectional view in FIGS. 3 and 4). Lining 3 is designed for mounting on the opening part of the vehicle. The locking compartment 4 is designed to accommodate, in particular, the swivel tongue 5 and the swivel dog 6.

The lock 1 may additionally contain a metal pad 9, partially covering the casing 2, coming into contact with the lining 3 so that the casing is not subjected to stresses and deformation during the fastening of the lock on the opening part.

The rotary tab 5 is configured to rotate around the axis of rotation of the axis 7 of the tongue between the open position (not shown) and the closed position (Figs. 1 and 2) of the lock, in which it interacts with the bracket 21 mounted on the body 20 of the vehicle at the end opening parts.

For this, the rotary tab 5 has the shape of a fork, while the bracket 21 is designed to pass through the opening of the lock 1 into the cutout 8 of the rotary tab 5.

The pivot tab 5 is held in a closed position by the pivoting dog 6 cooperating with the corresponding recess of the pivot tab 5.

As shown in FIG. 3, the pivot tab 5 is a metal body 14, which may at least partially comprise a coating 15 made of plastic material made by additional molding, in particular, to reduce knocking and friction between parts coming into contact with swivel tongue 5.

Outside the closed position of the rotary tab 5, its end 10 abuts against the damper 11 of the lock 1 (figa, 5b). The damper 11, made of, for example, rubber, allows you to cushion and stop the pivot tab 5 at the end of the closing stroke in addition to the door hinge when it is not enough to prevent an impact between the opening part and the body, for example, in case of too much energy of the opening part being slammed or in the case of a door hinge with too little compression resistance.

The pivoting tongue 5 comprises a through cylindrical hole 12 cooperating with the corresponding guide bearing surface 13 of the lock 1 for rotation about the axis of rotation I between the open position and the closed position of the lock 1. In the embodiment shown in FIGS. 3 and 4, the guide bearing surface 13 is formed the cylindrical section of the axis 7 of the tongue of the lock 1.

As is more clearly shown in FIGS. 6a, 6b, 7a, 7b, 7c and 7d, where, in particular, a pivoting tongue 5 without an additional cast element is shown, the metal body 14 comprises compensating thickenings 16a, 16b, 16c, 16d, 16e, 16f protruding around a through cylindrical hole 12 from two sides of its ends.

Compensatory thickenings 16a-16f interact with the corresponding guide bearing surface 13 to direct and center the rotation of the tongue 5 with good resistance to force, temperature, wear and fixation.

In this embodiment, the compensation bumps 16a-16f protrude alternately on each of the two flat sides 5a, 5b of the pivot tab 5.

In addition, they are uniformly distributed in the angular direction around the through cylindrical hole 12, which allows for good retention and good direction of the pivot tab 5 in the corresponding guide bearing surface 13.

In particular, the first flat side 5a of the pivot tab 5 contains, for example, three first compensating pockets 16a, 16c, 16d evenly distributed around the first end of the through cylindrical hole 12. The opposite flat side 5b of the pivot tab 5 also contains three second compensatory pockets 16b, 16e , 16f uniformly distributed around the opposite end of the through cylindrical hole 12. The first 16a, 16c, 16d and second 16b, 16e, 16f compensatory thickenings are offset in the angular direction and alternately protrude on from sides 5a, 5b.

As shown in FIG. 3, the thickness e1 of the pivot tab 5 without the pivot bearing area and without the additional cast member is, for example, about 3.5 mm. Compensation thickenings 16a-16f allow locally to expand the surface of the through cylindrical hole 12 of the rotary tongue 5, interacting with the guide bearing surface 13, for example, approximately 0.75 cm on both sides of the Central plane M of the rotary tongue 5.

Thus, the point S formed by the intersection point between the axis of the staple thread G and the central plane M of the pivot tab 5 in the locking position of the lock 1 (see FIG. 2) is identical for pivot tabs having different thicknesses.

In particular, the central plane M of the pivot tab 5 remains centered relative to the guide bearing surface and, therefore, relative to the pivot dog 6. Similarly, the axis of the thread of the bracket G is well positioned relative to the pivot tab 5.

Thanks to the guide thickenings, the pivot tab 5 can enter the fixation compartment of the pivot tab of a larger thickness without making changes to it and keeping point S. Thus, for the same housing, the same lining and for the same pivot axis different sizes of tongues can be used. Due to this, standardization of locks is achieved, while most of the components, with the exception of the tongue, are common to different models of vehicles. Therefore, the same assembly lines can be used.

In addition, it is possible to perform rotary tabs of smaller thickness at lower cost, using traditional cutting methods, more economical than manufacturing methods using precision cutting.

Compensatory thickenings 16a-16f can be performed by stamping the metal body 14 of the rotary tongue 5 with the formation of additional reinforcement 17a-17f in the side of the rotary tongue, the opposite side, from which the compensatory thickening 16a-16f protrudes.

Compensation thickenings 16a-16f can be leveled due to the element made by additional casting (see figa, 5b). Additional casting makes it possible to equalize the thickness of the compensatory thickenings to eliminate the discontinuity of the support of the compensatory thickenings of the rotary tongue, while the mechanical strength properties provide the compensatory thickenings located below.

The additional casting coating 15 may also comprise ribs 18 on opposite sides of the tongue 5 (Fig. 8). The ribs allow you to compensate for the runout of the rotary tab 5 in the housing 2.

The thickness e3 of the additionally cast coating with the rib is, for example, about 0.8 mm.

The contact areas of the rotary tongue 5, subjected to the action of forces or intended to come into contact with the damper 11, may remain without additional cast coating.

In addition, the end 10 of the pivot tab 5, intended to abut against the damper 11, comprises at least one protrusion 19 located perpendicular to the plane defined by the flat side 5a of the pivot tab 5 (Figs. 7a, 7b).

The thickness e1 of the end 10 of the pivot tab 5 of the order of 3.5 mm is increased by the height of the protrusion 19, for example, about 1 mm, which gives the end 10 of the pivot tab 5 a thickness e3 of about 4.5 mm.

Thus, the protrusion 19 allows you to expand the end 10 of the rotary tab 5 to increase the contact section of the tab resting against the damper 11, and to improve the distribution of damping and, therefore, increase the efficiency of damping.

The protrusion 19 is obtained, for example, by deformation of the material of the metal body 14 of the rotary tab 5. The method of deformation of the material is more economical than the method of manufacture by precision cutting.

Thus, the locks are partially standardized for several car models with identical attachment points and the position of the S point, while they are easy to manufacture and have a lower cost.
