Description

Technical field

The invention relates to a mechanical locking device for blocking parts of a motor vehicle, comprising a housing in which a lock cylinder is provided, on which a disc is mounted on the pivot end of which a first pin protrudes from the surface. the shifting mechanism mandrel, the second locking mandrel being mechanically coupled to the disc.

BACKGROUND OF THE INVENTION

A number of known devices are used to secure motor vehicles against theft, the common aim of which is to block one of the vehicle assemblies and thereby prevent unauthorized use of the vehicle. Regardless of the rapid development of electronic systems, mechanical security devices are still in use.

A common feature of the most widespread group of mechanical locking devices is that by extending the locking mandrel, they block the movement of the selected component or motor vehicle assembly. The best known are the gearshift locks which lock the control lever in one position by turning the key of the lock cylinder. Obviously, instead of the shifting mechanism, it is possible to lock other vehicle assemblies, such as the clutch control arm, the injection device control, the fuel supply to the engine, the bonnet, and the like.

There are also known devices in which a number of locking pins can be pulled out simultaneously by turning the key of the lock cylinder, thereby blocking several parts or assemblies of the vehicle at the same time, for example the shift mechanism together with the bonnet of the vehicle's engine compartment.

From utility model no. 14483, an additional gear lever locking device is known, comprising a housing bracket having a flat slot guide on the upper side in which a slider and a pivotable locking pawl are slidably mounted, the slider being mechanically coupled to the lock pawl. A lock insert is provided on the upper side of the bracket, on whose pivot end a disc with an eccentric bearing pin is fixed, which engages a groove in the slider.

Utility model no. 8886, which discloses a device for locking a motor vehicle control mechanism, comprising a housing in which a lock cylinder is arranged on which a rotating end is mounted with a disc from which a projecting pin protrudes on which a pivot is mounted .

The aim of the technical solution is to modify the known device as easily as possible to allow simultaneous operation of two locking pins.

The essence of the technical solution

This object is achieved by a mechanical locking device for blocking motor vehicle components, comprising a housing in which a lock cylinder is arranged, on the pivoting end of which a disc is mounted, from which a first pin protrudes, on which the first pin is pivotably mounted. A second locking mandrel is mechanically coupled to the disc, according to a technical solution, characterized in that a second pin protrudes from the disc surface, on which the second pin is pivotably mounted, mechanically interconnected with the second locking mandrel.

The design according to the invention makes it possible to modify the known mechanical locking device at a minimum cost so that it is possible to simultaneously operate two locking pins.

According to a preferred embodiment, the first pivot is mechanically connected to the locking mandrel of the shifting mechanism by means of a flexible shaft.

According to a further preferred embodiment, the second bolt is mechanically connected to the second locking mandrel by means of a bowden cable comprising a stainless steel cable slidably mounted in a steel spiral.

According to further preferred embodiments, the second locking mandrel in the extended state may extend into the locking eye fixedly coupled to the vehicle hood, or may block the clutch control arm or the injection device control or fuel supply.

BRIEF DESCRIPTION OF THE DRAWINGS

A mechanical locking device for blocking components of a motor vehicle according to the invention will be described in more detail by way of example of a specific embodiment, shown in section in FIG. First

EXAMPLES

A mechanical locking device for blocking motor vehicle components according to the embodiment of FIG. 1 comprises a metal sleeve 10 in which a lock cylinder 11 is arranged. On the rotatable end of the lock cylinder 11, a disc 8 is fastened, from which the surface protrudes a first pin 7 and spaced therefrom at the opposite end of the disc 8 a second pin 20.

A first pin 6 is pivotably mounted on the first pin 7, which is connected to the locking mandrel 14 of a not shown shifting mechanism by means of a flexible shaft 18. The flexible shaft 18 is housed in a guide formed by a shaped metal tube 12.

On the second pin 20, a pivotably mounted second bolt 5, mechanically coupled to the second locking mandrel 19 by means of a bowden cable comprising a stainless steel cable 1, is displaceably mounted in a steel spiral 2. located in the holder 4 of the bowden housing 3.

The bowden cable 1 is attached to the second locking mandrel 19, which is slidably mounted in a guide 16 mounted in the holder 15 in the region of the front edge of the bonnet of the motor vehicle. In order to ensure smooth operation, the second locking mandrel 19 is pushed out of the guide 16 by a compression spring 17. A locking eye 13 is secured to the underside of the front edge of the hood of the motor vehicle, through which the second locking mandrel 19 can extend.

· 4-5

The sleeve 10 of the lock insert 11 is closed on the opposite side to the lock insert 11 by a bottom 9.

After insertion of the key into the lock cylinder 11, it is possible to turn the lock cylinder 11, which carries the disc 8 therewith. Together with the disc 8, the first pin 7 and the second pin 20 are rotated simultaneously. the locking shank 14 of the shifting mechanism and the second locking shank 19 are simultaneously extended through the flexible shaft 18. Thus, both the shifting mechanism (not shown) and the hood locking eye 13 are locked.

By rotating the lock cylinder 11 in the opposite direction, the two locking pins 14, 19 are retracted into the initial position and the respective components are unlocked.

It will be appreciated by those skilled in the art that the second locking mandrel 19 can, in the extended state, block other vehicle components or assemblies, such as the clutch control arm, the injection device control, the fuel supply and the like, instead of the vehicle hood.
