Definitions

  • the present invention relates to an electric security lock more especially for doors of motor vehicles or the like which has been studied with a view to obtaining a product of very low weight in order to be able to be easily mounted on modern motor vehicles while obtaining however a lock which exactly meets the safety standards and which can be remote controlled so that all the doors as well as the engine cover, the cap of the fuel tank cap as well as the top of the trunk are unlocked by a single operation.
  • the electric security lock is used for unlocking a door, in particular for motor vehicles, in order to allow its opening; this is why all the usual control levers have been removed and simply replaced by an electronic device which only works when it is programmed for unlocking.
  • this embodiment provides a certain number of complements.
  • This electric security lock allows the locking of rear doors when transporting children and also meets American anti-rape security standards to protect the passenger or passengers of the vehicle if it is parked.
  • the present invention provides an electric lock whose main characteristic is the electric unlocking of the lock, so the opening by rotation of the door is done by a simple movement, and it is the pressure of the seals surrounding the door which pushes the latter so that it opens.
  • the plate is shown on which is fixed on one side the housing 1 which contains in its right part an electric micro-motor 2 whose shaft 3 carries a pinion 4 which meshes with a toothing 5 carried by a cup 6 secured to a shaft 7, the central part of which is provided with an endless screw 8.
  • the shaft 7 rests in bearings 9, 10 of the housing 1.
  • the latter is fixed by screws 11 on the plate 1a.
  • a casing 12 of substantially rectangular shape see FIGS. 4 and 5 which contains, on the one hand, a ratchet 13, and on the other hand, a bolt 14 which will be described further.
  • the worm 8 placed in the housing 1 meshes with a cam 15 also placed in the housing 1, a cam which has a shoulder 16 coming to bear on the inner face 1b (see fig. 3) of the housing and, also, an extension circular 17 centered on a boss 18 on the front face of the housing 1.
  • the circular extension 17 externally carries a toothing 19 which permanently meshes with the worm 8 of the shaft 7.
  • the cam 15 cooperates by its step 1 5a with a pin or thrust pin 20 which, through a curved window 21 pierced in the housing 1, and in the inner wall of the casing 12, is in connection with the ratchet 13.
  • this ratchet 13 can rotate under the action of the pin 20 around the axis 13a of which it is integral and which is mounted in the walls of the casing 12.
  • the pointed front end 13b of the ratchet 13 is intended to cooperate with the teeth 14a of the latch 14 which is also mounted in rotation on an axis 23 integral with the walls of the casing 12.
  • the bolt 14 includes a cutout 24 of substantially circular shape and into which the bar 25 which constitutes the keeper of the lock, keep keeper fixed on the frame or frame of the door.
  • the supply of the motor 2 causes the rotation of the worm 8, the rotation of the cam 15 and therefore the rotation of the pin 20 which unlocks the ratchet 13 of the teeth 14a of the bolt 14 thereby releasing it which can easily pivot in the direction of arrow F4 (fig. 4).
  • the door can therefore open since the keeper 25 is released.
  • this lock is controlled either by the switches mentioned above in FIG. 7, or using the key specific to the car in a known manner and which acts on the switches 43, 44.
  • this lock is very much lighter in its electrical construction than locks whose control functions are carried out either by an electro-mechanical element or by a pneumatic cylinder.
  • the lock 80 consists of a housing 86 containing an electric motor 87 supplied from cables 88-89.
  • the shaft 87a of the motor 87 rotates a pinion 90 guided during its rotation by a bore 91 hollowed out in the front part of the housing 86.
  • the pinion 90 cooperates with a reduction gear 92 constituted by a first pinion 93 meshing with a double toothed crown 94 held by a fixed crown 95 and with a pinion 96, which makes it possible to obtain a reduction in the speed of rotation of the motor 87.
  • the pinion 96 has, on its front face, the shape of a cam 96a which, when it rotates in the direction of the arrow F40 (fig. 12) has the effect of driving in rotation, in the direction arrow F41 a finger 99 whose displacement is possible in a curved window 100 open in the plate 101 closing the housing 86.
  • the pin or finger 99 is integral (see fig. 8) with the ratchet 113 placed inside the casing 112 mounted on the other side of the plate 101.
  • 11 3a designates the end tooth of the ratchet 113 which is mounted on an axis 114 around which is placed a pressure spring 115 tending, by means of its free ends, to push the pin or finger 99 in the direction of the arrow F42 (fig. 8).
  • a pressure spring 120 permanently tends to rotate the bolt 116 in the direction of arrow F43 (fig.8).
  • the hook 97 has on a part of its periphery two guides 97a-97b on which are mounted flexible cables 125 allowing in the event of non-supply of electric current, and by pulling these cables 125 in the direction of the arrow F45 (fig. 12) to unlock the ratchet 113 of the bolt 116 to release the latter.
  • 98 is the axis on which the ratchet 97 turns.
  • the bolt 116 is pivoted completely in the direction of the arrow F43 (fig. 8) and thus, by bringing the door closer to the frame 84, one can easily make the strike 82 enter the bolt 116 which causes the pivoting of this bolt 116 in the opposite direction to arrow F43.
  • the ratchet 113 first enters the tooth 118 and then into the tooth 119 of the latch 116. The door is thus locked since the keeper 82 is trapped inside the latch 116, itself locked by the ratchet 113, which is itself blocked by means of the pin or finger 119 and the spring 115 (movement in the direction of arrow F42 of the ratchet 113).
  • the supply circuits of the various motors 87 are then closed for each by a contact switch 140 (see fig. 11) controlled by a second cam 96b of the pinion 96.
  • each motor drives, via the pinion 90, the reduction gear 92 which rotates the cam 96 in a turn so that the pin or finger 99 is raised in the opposite direction to the arrow F42 (see fig. 8 ) thus causing the unlocking of the ratchet 113.
  • Each bolt 116 being free, each pressure spring 120 causes the rotation, in the direction of arrow F43, of the bolts 116 which release each keeper 82. Under the pressure of the seals the doors and covers can then rotate towards the opening.
  • the locks according to the invention are intended for unlocking, that is to say unlocking, to allow the opening of a door or a cover using the pressure of seals on doors and covers to separate the elements of the lock from the strike concerned.
  • the motor control by electronic control allows the external control and the internal control, the "child” safety preventing the untimely unlocking of the doors as well as the locking of the doors and covers known as "anti-rape safety" provided for by the regulations of certain foreign countries.
  • FIG. 13 an electrical diagram in which for a passenger vehicle four motors 87A, 87B, 87C, 87D have been indicated, the supply of which is made from a battery 130 by means of a conductor 131 leading to an electronic circuit or microprocessor 132 and from there to circuits 133, 134, 135, 136.
  • the doors cannot be opened from inside the vehicle if they have not been unlocked before from the outside (theft protection).
  • 87 designates a control lamp or lem.
