Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
182 words
Electric safety locks, more specially designed for motor vehicle doors, in which each of the vehicle doors including the motor bonnet, the petrol tank cap and the luggage boot of the vehicle are equipped with a set consisting of a case (1) in which an electric micro-motor (2) is mounted, and wherein a shaft (3) of the motor drives a pinion (4) cooperating with a reducer which permanently engages with a toothed cam (15) having a protruding part (15a) which cooperates with a pushing finger (20) which passes through the case (1) and an anterior wall of a casing (12) so as to control rotation of a ratchet (13) having an end tooth (13b) which engages into teeth of a rotating bolt which is mounted in the casing (12) and comprises a cut opening (24) which receives a bar (25) which forms a lock-staple (25) and that supplying of the motor is monitored by a printed circuit which enables, by using switches (40, 41, 42, 43, 44) the door to be open or temporarily closed for protection of occupants of the vehicle.
Claim 2
Dependent Claim
182 words

Claim 3
Dependent Claim
32 words
Electric safety lock according to claim 1, wherein the cam (15) cooperates with a deformable finger (46) of a limit micro-switch for stopping or beginning a supply operation of the micro-motor (2).
Claim 4
Dependent Claim
27 words
Electric safety lock according to claim 1, wherein the case (12) comprises in its inner side an opening (27) for introducing the bar (25) functioning a staple.
Claim 5
Dependent Claim
18 words
Electric safety lock according to claim 1, wherein the opening (21) receiving the pushing finger (20) is curved.
Claim 6
Dependent Claim
97 words
Electric lock more specially for vehicle doors according to claim 1, wherein the motor (87) drives through said pinion (90) the reducer (92) causing rotation of a second pinion (96) during a complete rotation so that the toothed cam (96a) operatively connected to said second pinion causes the pushing finger (99) to move which controls the rotation of the ratchet (113), a tooth (113a) of which, when disengaging the teeth (118, 119) of the rotating bolt, disengages by intermediary of a resilient element (120) the lock staple (82) rigidly fastened to a frame of the corresponding door.
Claim 7
Dependent Claim
44 words
Electric lock according to claim 5, wherein the ratchet (113) is permanently submitted to action of a compression spring (115) which holds the tooth (113a) of the ratchet (113) in the teeth (118, 119) of the rotating bolt (116) while the door is closed.
Claim 8
Dependent Claim
46 words
Electric lock according to claim 5, wherein the bolt (116) is submitted to action of a compression spring (120) which is coaxially mounted on a pin (117) of the rotating bolt (116) and tends to cause said rotating bolt (116) to turn in direction of opening.
Claim 9
Dependent Claim
55 words
Electric lock according to claim 5, wherein an idle hook (97) mounted on a pin (98) of the casing is controlled by hand through a cable (125) so that the pushing finger (99) is allowed to turn whereby the ratchet (113) raises and the bolt (116) is unblocked in order to open the corresponding door.
Claim 10
Dependent Claim
37 words
Electric lock according to claim 1, wherein the reducer comprises a disc shaped part (6) fixed at the end of a shaft (7) supported by bearings (9, 10) and comprising in its center an endless screw (8).
