Description

We are using locks more and more

  electrical and in particular these electrical locks

  triques are used on land vehicles such as passenger cars which are fitted with engine hood locks, trunk hood locks,

  electrically operated door rags

  which obeys an electronic device allowing the total or partial condemnation of these locks either during the period when the vehicle is stopped (parked vehicle) or temporarily (safety lock for children or for imposed standards (anti-violence device)) . These locks must be fitted

  in the event of a power failure of devices allows

  try to open the doors manually from inside the vehicle or using a manual key allowing

unlocking locks.

  In addition, the use of electric locks

  triques which very often include in addition to the normal source of energy (electric battery of the vehicle) an additional source of emergency energy constituted by a battery normally rechargeable by the alternator of the vehicle but for a psychological purpose in order to show the passenger that even if these two sources of energy fail for any reason there is no

  of danger, a safety device is provided

  additional installed on the locks.

  The present invention therefore relates to a second

  security which is constituted by a bolt either maneuver-

  ble by hand using a key when you are out of the car or that is activated automatically in the event of a complete failure of the two other sources which is particularly important in an accident from the road, allowing you to open from the inside

  doors and hoods.

  In accordance with the invention, a box fixed by suitable means to the sheet metal of the body of the vehicle in question, this shoemaker internally contains, in a cell, a micro-contact subjected to the central servo-control of the vehicle locks and connected by

  through the cable to a source of electrical energy

  that allowing the drive of a motor whose shaft carries a latch normally held horizontally by a spring, motor and battery being placed inside a recess of a hollow bar on which rests a unlocking bar comprising a notch intended to receive the upper end of the latch, then the

  bar has, at its front part, a cable tie assu-

  rant the junction of the sheathed cable for the manual control of unlocking the locks, the bar and the superimposed bar sliding in the chamber of the bootmaker being held in place laterally by a

  plate fixed on the inside of the case.

  According to another characteristic, the outer end of the bar has a junction point which can be actuated directly or indirectly by a key

in and out of the vehicle.

  Various other features of the invention

  moreover emerge from the detailed description which

  follows. An embodiment of the object of the invention is shown, by way of nonlimiting example, at

attached drawing.

  -Fig. 1 is a top view of the control

manual security.

  Fig. 2 is a side elevation of the com-

internal side.

  Fig. 3 is a section along line III-III

of fig. 2.

  Fig. 4 is an elevation view, internal side

  closed, control, according to the invention.

  As can be seen in the drawings, this control consists of a housing 1 of substantially shaped

  rectangular parallelepiped normally produced by

plastic lage.

  This housing 1 is fixed by screws 2 on the interior

  sheet metal laughter 3 constituting, for example, an element of the bodywork located in the frame of the door covers and other movable elements locked by a

electric lock.

  The housing 1 has a cell 4 at its upper part of which is placed a microswitch 5 which is connected via the cables 6 to the circuit

  general power supply for controlling electric locks

  triques. Under the cell 4 is provided a chamber 7 which contains a bar 8 of rectangular section placed at the top of the chamber 7 and which is connected by a junction point 9 to a linkage 10 allowing in certain cases, the sliding of this bar 8 in

  the direction of arrow F1 (see fig. 1 and 2).

  The bar 8 has, in its central zone, a notch 11 into which may penetrate in certain cases, the upper end 12a of a latch 12 articulated on a shaft 13 secured to an electric motor 14, this assembly being placed in a recess 15a of a second bar 15 of rectangular section disposed under the

bar 8.

  This second bar 15 is housed under the bar 8

in chamber 7 of housing 1.

  Behind the motor 14 is placed a battery 16 which is connected to the motor 14 via the cable 6a to

  through the micro-contact 5. The cable 6 allows the supply

  tation from the alternator of battery 16 recharged-

  corn. When the current voltage drops in abnormal section

  badly the printed circuit which maintained in tension this battery and of this fact the latch 12. subjects before the complete cut of current the micromotor 14 to the food by the rechargeable battery 16 and of this fact allows the

  movement of the latch 12 which then takes position

  tion in the opening or notch 11 made in the unlocking bar 8. In this case, there is the possibility of driving this bar 8 when there is a junction on the opening control constituted by the bar 15. In addition, and as can be seen in FIG. 3, the latch 12 is normally in the horizontal position drawn in phantom (fig. 3) under the action of a small spring centered on the shaft 13 and which maintains the

  latch 12 in a substantially horizontal position.

  Finally, the bar 15 is connected by the inter-

  middle of a cable clamp 17 to a cable 18 placed in a sheath 19. The cable and the sheath 18-19 are of the Bowden type commonly used in industry and for

vehicles.

  Finally, the above-described device is closed on its internal side by a plate 20 fixed by

screw 21.

  Junction point 9 (see fig. 4) can

  also be connected by a connecting rod 23 to a shaft 24 turn-

  in a bearing 25 integral with the plate 20 so

  to operate the junction point 9 using a key 26.

  This key is safety, it can be the one used

  for starting the vehicle or any other.

  The bars 8 and 15 are generally molded plastic parts while the latch 12 is

made of metal.

  In the case where the central lock control

  electric vehicle finds that the main race

  of energy and the secondary source of energy are down either because these sources no longer contain energy or because the connections are broken for example following an accident, the micro-contact 5 immediately connects the battery 16 to the motor 14 which is driven on a quarter turn which makes it pivot in the direction of the arrow F2 (see fig. 3), the latch 12 which penetrates, against the action of the aforementioned spring which keeps it normally horizontal, in the notch 11 of the bar 8

  thus making the bar 8 and the bar 15 integral.

  Thus, if, using a manual element such as a key or a handle, the junction point 9 is pulled in the direction of the arrow F1, the rod 15 is driven and, with it, the cable 18 thus making it possible to unlock

  manually all the locks of the vehicle in question.

  Doors, hoods and the like open

at once.

  Although all of the above description has been made

  from vehicles fitted with electric locks, this manual safety control device can also be used in the event that the locks are actuated

  by a source other than electric current for example-

  ple pneumatic control; indeed, orders

  tires are always controlled by an electric central

  which allows the micro-

  contact 5 supplying motor 14 from battery 16

manual safety control.
