SU1194289A3 - Double-blocked automobile ignition lock - Google Patents

Abstract

Double-action lock for the ignition starting switches and steering systems of motor vehicles, which lock is provided with a special disc (5), on which rests a locking bolt (11) which interacts with the locking bar (6) of the steering lock. When the key is inserted, the disc (5) is displaced into a central position, so that the locking bolt (11) is displaced, causing the head part of the bolt (11) and the locking bar (6) to be aligned with one another, and so that raising of the locking bar (6) causes it to be stopped in the unlocking position. <IMAGE>

Description

 eleven

The invention relates to an ignition lock which, during movement, ensures the release of double locking of an erase lock mounted with an automobile ignition switch.

The purpose of the invention is to improve the reliability of the lock.

FIG. 1 shows the lock in section, a general view; in fig. 2 is a section AtA in FIG. t; in fig. 3 - faktat. the castle; in fig. 4 - the same, option. - .....; / Lock. Ignition. Includes In, an ignition switch containing 1 molded case 1 switching unit 2 with. contact pairs (not shown) for all necessary contacts, and the lock itself .-. . . . .

A rotor 4 mounted in the stator 3 is connected with the switching unit. The latter contains a locking section, having seven locking plates (not shown) - interacting with a symmetric key (not shown), and a control ring 5.

The lock contains locking means, including: e clamp 6, spring-loaded spring 7 from one end and interacting with control ring 5, locking plate 8 embedded in the lock rotor and coaxially mounted with radial / displacement and interacting with spring-loaded lock 6 when HELP POSITION 9.

The locking means has an additional locking assembly containing a plate spring 10 fixed on the fixture and interacting with the stopper 9,

The free end of the retainer 6 is provided in the form of a fork. In this case, the retainer has a groove 11 of conical shape made at its free end and communicating with the groove 12 of the fork. A hole 13 is made in the stator, a stopper 9 is installed in the stator aperture 13 with the possibility of longitudinal movement and placement in the slot 11 of the lock 6..

A return spring 14 is installed in the recess of the control head 5, and a pin 15 is installed in the radial opening of the control ring 5 to prevent restarting. A tilted guide ring 16 of the control ring 5 provides for movement.

Latch 6 lock in the direction of opening (release {).

The lock works as follows. FIG. 1 lock is represented in the stop position. After insertion

the key locking plate 8 moves to the central position and moves the stopper 9 in the radial direction, due to this the head part of the stopper is leveled with the lock 6

lock and prepare. lock (unlocking).

When turning the lock, the control ring 5 unlocks the latch 6,

5, the lockable position of the control lock is unlocked the most, and in the upper position it is locked by means of the stopper 9. Double locking is provided in the state

The Q movement in that the lock is turned off is prevented by both the control guide 16 and the lock.

The locking is carried out in such a way that the head of the stopper 9 for

5, the upward-locking jj is displaced in the radial direction and after the subsequent release of the leaf spring 10 enters inside the opening 11 of the conical shape.

The additional blocking unit may include a folding bar 17 mounted on the latch 6 for contact with the stopper 9 and the plastic / hemp strip 10, while the free end of the latch is made with a bevel 18,

 In this case, the locking is performed by the fact that the flap 17 mounted on the upwardly moving latch 6 is deflected before heading the stopper 9 and with further lifting is locked. Under the action of the plate spring 10. Due to the release on the latch 6 of the bevel 18 the flap 17 self blocking.

The lock can only be locked when the rotor is turned in. The position of the stop and key is pulled out. .

Application lock proposed

constructs prevents

restarting a running car engine. The rotor and the locking section are small in size, as a result of which an electrical switch unit of appropriate dimensions can be integrated into the ignition lock 55, which does not require an increase in the previously known dimensions.
