Electromechanical ^. ¹ remote control mechanism for locking and unlocking, ·. Locks

The invention relates to an electromechanical remote control mechanism for locking and unlocking locks on doors, trunk lids or bonnets of vehicles.

Known electromagnetic systems for remote control of the Locking or unlocking of locks for doors, trunk lids or hoods of vehicles require due to the devices required to move: the devices they control Force and the required path relatively heavy and space-consuming electromagnets, in many cases in pairs must be provided so that both locking and unlocking is possible.

The invention is based on the object of an improved and to provide simplified electromechanical remote control mechanism of the type mentioned, which has only one Electromagnets required for locking and unlocking and continue to have a reduced manufacturing price and has a lower need for trees.

This object is achieved by the invention specified in claim 1.

Further advantageous designs and developments of the invention emerge from the subclaims.

Due to the design of the remote control mechanism according to the invention, only one electromagnet is required, which both for locking as well as for unlocking and which additionally requires a reduced space requirement and a reduced Has weight.

The invention is explained in more detail below with the aid of an exemplary embodiment shown in the drawing.

In the drawing show:

1 shows a perspective view of an embodiment of the remote control mechanism for locking and unlocking a lock of a vehicle, the housing being shown partially broken away

Fig. 2 is a rear perspective view of the upper part a mechanism of Figure 1;

Fig. 3 is a sectional view of the main pivot axis and the elements driven by it on the upper part of the remote control mechanism according to FIGS. 1 and 2;

Fig. 4 is an electrical circuit diagram of the supply and control circuits a3 remote control mechanism for locking and unlocking locks.

In the Pigg. 1 to 4 is an electromagnetic remote operating mechanism shown for locking and unlocking in particular for automobile locks, the one electromagnet 1 includes with a dipping grain. The upper part of the Tauchkeras cooperates with a rocker arm 2 on which in the middle a pawl 3 is articulated, which in The drive force is transmitted to a gearwheel 4 in a tangential direction can, while an auxiliary holding pawl 5 Any danger of a Return of the gear 4 during the return movement of the pawl 3 avoids under the action of a spring which is attached on the one hand to the pawl 3 and on the other hand to the housing 1st and those shown along the lines with dotted lines Direction 6 is effective.

The rocker arm 2 has an auxiliary arm firmly connected to it, the lower part of which, in the form of a fork, actuates and moves the upper part of the switching arm (swing arm) of a miniature switch 7 which is arranged in the housing 10.

On the other hand, the gear 4 is rigidly connected to the upper axis of rotation 8, on which the actuating crank arm continues 9 and adjacent electrical contact disks 11, 12 and 13 are distributed * each with corresponding Grinders or brushes 14, 15 and 16 can come into contact, it should be noted that "each of the grinders 14 and 15 only over half a turn and with an angular offset of 180 ° with the corresponding disks 11 and can come into contact while the grinder 16 is constantly in contact with the central circular disk .13.

Having thus described the remote control mechanism with reference to Fig. 4, it will be readily understood that, for example the actuation of the locking of one or more

Locks a vehicle by simply turning the switch can be done to the right »In this position of the switch, the grain from the vehicle's battery flows through« meftde electric current the grinder 14 and the protruding the part of the corresponding half disk 11 and then over the adjacent disk 13 and the associated grinder 16 through the miniature switch forming a chopper? and the wick * development of the electromagnet 1, the excitation of which is the attraction of the Immersion core3 causes.

This first tightening of the plunger causes the rocker arm to tilt 2 öm counterclockwise Lnn (with reference to Fig. 1), whereby the port scarf th around a fence of the ratchet wheel 4 in Clockwise with the help of the pawl 3 and also the lower « breaking of the excitation circuit via switch 7 is effected, which causes a tilting and thus a return to the rest position of the plunger core of the electromagnet 1 is connected. At the same time, the electromagnet is energized again Via the small switch and thus a repetition of the successive ones Advancing movements of the ratchet wheel 4 by one tooth to over half a turn. After this half turn if the grinder 14 leaves the disc 11 and the current of excitation * circle is interrupted, at which point the one to be actuated Söhloß is locked.

In this position, the reverse movement for unlocking is now possible, due to the fact that at the point in time at which the grinder 14 has left the disk 11, the protruding part of the half-disk 12 came into contact with the grinder 15 is.

If now the switch is gfebraent in the reverse position * i.e. üaöh is turned to the left, it can be seen from Fi ^ * 4,

that the current is now through the grinder 15 and the half-disk 12, over the adjacent disc 13 and the associated Grinder 16 flows to the chopper 7 to finally re-energize the electromagnet 1, which in turn causes the rotation of the ratchet wheel 4 is caused., in one process, which is identical to that described above and

over a new turn of the bellows, after this half turn the wiper 15 leaves the disk 12 and the excitation current circuit is interrupted in the unlocked position.

Each of these successive half turns corresponds in the same way to a half turn of the actuating crank arm 9 «the one with the usual drive lever of every lock connected,. so that finally the simultaneous locking or unlocking any number of such locks is enabled.

In this regard it should be noted that as a first approximation for a distance of 15 mm required for locking or unlocking and a useful stroke of the core of the electromagnet of 4 mm, the 18 shark for half a [turning of the crank arm 9 is repeated, practically a useful stroke of the electromagnet is achieved compared to the direct actuation such facilities is five times enlarged, whereby the use of a factor of downsized electromagnet is made possible.

Furthermore, the efficiency is increased by the fact that the useful stroke of the plunger is effective only during the fraction is used, which corresponds to the maximum tightening force.

Finally, it can be seen that the invention does not apply the exclusive combination of the expressly described devices and methods as well as the only mentioned
