Description

Mechanical lock for blocking motor vehicle components

Technical field

The invention relates to a mechanical lock for blocking parts of a motor vehicle, comprising a housing in which a lock cylinder is arranged, on the pivoting end of which a disc is mounted, with a pin protruding from its surface. wherein a second locking mandrel is 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 assembly of the motor vehicle. Known are locks of the shift mechanism that lock the control lever in one position by turning the key in the lock cylinder. Obviously, instead of the shift 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, etc.

Devices are also known in which, by turning the key in the lock cylinder, several locking pins can be pulled out simultaneously, 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. On the upper side of the bracket there is a lock insert, on the pivot end of which 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

Said object is achieved by a mechanical lock 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, with a pin protruding from its surface, mechanically interconnected with a locking spindle of the shift mechanism. wherein a second locking mandrel is mechanically coupled to the disc, according to a technical solution, characterized in that on the one hand the first bowden cable leading to the shift mechanism locking mandrel and the second bowden cable leading to the second locking mandrel are attached to the common pin.

The construction 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 control two locking pins.

According to 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 lock 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.

1. FIG. 2 is a detail of the lock cylinder and the attachment of the bowden cables.

EXAMPLES

A mechanical lock 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 rotating end of the lock cylinder U is fixed a disc 8, from which a protruding pin 7 protrudes, on which a pin 5 is pivotably mounted. to the locking mandrel 14 of the shift mechanism 4 and secondly to the second bowden cable 2 leading to the second locking mandrel 19.

The locking mandrel 14 of the shift mechanism 4 is slidably mounted in a guide 18 mounted in the holder 3 and, in the extended state, can pass through the locking eye 6 arranged on the shaft of the shift mechanism 4. To ensure smooth operation, the locking mandrel 14 is forced out of the guide 18 by a compression spring 17.

The second locking mandrel 19 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. To ensure smooth operation, the second locking mandrel 19 is also pushed out of the guide 16 by means of a compression spring 17. On the underside of the front edge of the bonnet of the motor vehicle there is a locking eye 13 through which the second locking mandrel 19 can extend.

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

After inserting the key into the lock cylinder 11, it is possible to turn the lock cylinder 11, which carries with it the disc 8, the pin 7 and the pin 5. When the disc 8 is rotated, the pin 5 extends the steel cables 1, 2. Thus, the shift mechanism 4 and the bonnet lock eye 13 are simultaneously 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.

4-Γ

It will be appreciated by those skilled in the art that the second locking mandrel 19 may, 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.
