Definitions

  • the present invention relates to a lock, in particular for the door of a motor vehicle, of the type comprising an unlocking control device and a locking device, at least one of which is part of a closed hydraulic circuit.
  • the invention aims to provide a lock allowing, in a simple and economical way, the liquid to expand freely under the effect of significant temperature variations, without interfering with the operation of the device in question.
  • the invention relates to a lock of the aforementioned type, characterized in that the hydraulic circuit is provided with an expansion tank with which is associated a check valve adapted to not allow the return of the liquid in the tank only at very low flow rates.
  • the lock according to the invention When the lock according to the invention is intended to equip an automobile door, it comprises an interior unlocking control device and an exterior unlocking control device.
  • an interior unlocking control device When the lock according to the invention is intended to equip an automobile door, it comprises an interior unlocking control device and an exterior unlocking control device.
  • Standardization can be pushed to a high degree when the locking device comprises a single block provided with several distributors and with a network of conduits for the connection of a liquid reservoir, of a desired number of emitting pumps and at least one cylinder for unlocking the lock.
  • Fig. 1 shows a car door 1 in the thickness of which is mounted a lock 2 with fully hydraulic control.
  • the unlocking member 3 of this lock is attacked by the rod 4 of a jack 5 connected to a hydraulic circuit 6 which contains a liquid such as a mixture of water and antifreeze.
  • a hydraulic circuit 6 which contains a liquid such as a mixture of water and antifreeze.
  • two pumps are connected 7, 8 actuated respectively by an exterior button 9 and by an interior unlocking control button 10, as well as a locking device shown diagrammatically by a block 11 to which two pumps 12, 13 are connected, actuated respectively by an exterior key 14 and by an interior frieze zipper 15, as shown in phantom.
  • the entire circuit 6 is a closed circuit comprising a liquid reservoir 16 forming an expansion tank and is housed in the door 1.
  • the pumps 7, 8, 12 and 13 can for example be of the piston-cylinder type, of the type with rolling membrane or of the bellows type. In what follows, we will assume that they are of the cylinder-piston type.
  • Fig.2 shows a simple example of the circuit.6 ensuring only the unlocking and the condemnation of the external unlocking control.
  • the block 11 comprises a two-position two-way distributor 17 and a check valve 18, the inlet of which is connected to the reservoir 16 and the outlet of which is connected by a conduit 19 to the outlet of the distributor 17.
  • the inlet of this distributor is connected to the outlet of the pump 7, and; its movement is controlled either by the pump 12 of the key 14, or by the pump 13 of the pull tab 15 connected to the distributor in parallel.
  • two pipes are connected, one of which leads to the outlet of the pump 8 and the other 21 to the inlet of the jack 5.
  • the distributor 17 is replaced by a distributor 22 with two positions and three ways, one of which outlet is connected directly to the reservoir 16 and the other to the conduit 19.
  • the actuation of the button 9 sends liquid either in the conduit 19 (unlocked lock), or in the reservoir 16 (lock condemned).
  • the vessel 16 comprises a base 23 having the shape of a disc provided on its upper face with elastic peripheral lugs 24, on its lower face with a connection tube 25, and in the center of an orifice 26 counter-bored upwards.
  • a reservoir 27 in the shape of an inverted cup with a pierced bottom snaps into the tabs 24 by pressing on the base 23 a plate 28, which has a small hole.
  • central 29 counter-bored downwards, and a membrane 30. The central part of the latter is cut into three quarters of a circle to define a swinging tongue 31.
  • the reservoir 27 communicates with the atmosphere.
  • Figs. 7 to 10 show four types of distributors that can be used in the circuits of Figs. 2 and 3.
  • the distributor 17 of FIG. 7 corresponds to the locking condemnation of FIG. 2, while the other three are used for locking by disengaging in FIG. 3:
  • the distributor 22 of FIG. 8 is of the simple sliding drawer type 34, that 22A of FIG. 9 with sliding drawer 35 actuating two tilting valves 36 returned to the closed position by springs 37, and that 22B. of Fig. 9 of the three-way rotary drawer or plug 38 type.
  • each distributor 22 can be carried out by one of the actuating devices shown diagrammatically in FIGS. 11 to 13.
  • Fig. 11 two identical pumps 39 and 40 are actuated in opposite directions and in synchronism by a common lever 41 and are respectively connected to the two ends of the body of the distributor 22, so that when one pump delivers liquid, the other sucks it up an equal amount. Note that the expansion / contraction of the liquid acts in a balanced manner on the pumps 39 and 40 and therefore does not risk inadvertently actuating the dispenser.
  • a single pump 42 is connected to one end of the body of the distributor 22, the other end of which communicates by a conduit 43 of this body with the outlet of the distributor which is connected to the vessel 16.
  • the pump 42 discharges liquid into the first end of the dispenser or draws liquid into this end according to its direction of movement.
  • the actuating rod 44 of this pump comprises a device 45 defining two stable positions, constituted for example by a ball loaded by a spring and cooperating with two recesses spaced from the rod 44.
  • the force of the device 45 is chosen so as to counter the effects of liquid expansion / contraction.
  • Such a device can also advantageously also equip the lever 41 of FIG. 11.
  • FIG. 13 The preferred arrangement of FIG. 13 is similar to that of FIG. 12 with the exception of the device 45A for holding in position.
  • This device indeed comprises an extension 46 of the drawer 34 with two peripheral V-shaped grooves 47 which is received in a cavity 48 extending the main bore 49 of the dispenser.
  • the end of the cavity 48 is closed with a seal by a plug 50 on the inner face of which protrude a central stop 51 for the extension 46 and, on either side of the latter.
  • two leaf springs 51a the curved end of which can engage in one or other of the grooves 47 to axially retain the drawer 34.
  • the pump 42 is moreover connected by a throttled bypass duct 52 to the vessel 16, to prevent the expansion or contraction of the liquid trapped between this pump and the associated end of the distributor inadvertently causing the latter to be actuated .
  • the conduit 52 also ensures equalization of the pressures in the circuit after a short time, on the order of a few seconds. This allows to use to actuate the pump 42 an elastic return button in the neutral position. It is then possible to connect several pumps such as 42 in parallel, and it is ensured, with correct sizing, that the actuation of these pumps will not cause the position of the other pumps to change.
  • Fig.14 is a diagram of a front door lock control of a motor vehicle.
  • the block 11 comprises a conduit 53 which connects one end of the distributor 22 to the conduits 20 and 21.
  • the actuation of the interior button 10 brings the distributor into the unlocked position.
  • buttons 9 and 10 with an elastic return spring, so that these buttons provide unlocking pulses by simple pressing.
  • this elastic return of the buttons 9 and 10 can be ensured by the pressure of the circuit 6, without any spring being necessary. In this case, the slow return of the button 10 does not risk bringing the distributor 22 into the locked position. Otherwise, little used in automobiles, of a button 10 with positive feedback, the dimensioning of the hydraulic members would easily make it possible to avoid the return of the distributor 22.
  • another distributor 54 of the same type is interposed between the locking pins 12 and 13 and the end of the distributor 22 opposite the conduit 53.
  • the input of the latter is connected to pumps 12 and 13, mounted in parallel; one of its outputs is connected to the distributor 22, and its other output to the vessel 16.
  • One end of the distributor 54 is connected by a conduit 55 to a pump 56 sensitive to the locked or unlocked state of the lock 2, for example sensitive to the position of the locking member of this lock.
  • the pump 56 brings the distributor 54 into its position for prohibiting locking, in which its inlet communicates with its second outlet and, from there, with the vessel 16.
  • the actuation of the key 14 or the pull tab 15 is then inoperative vis-à-vis the main distributor 22, and the latter therefore remains in the unlocked position. This avoids closing a door that has already been locked and therefore forgetting the key inside the vehicle.
  • the full locking of the lock 2 causes the return of the dispenser 54 to its locking enabling position illustrated in Fi g. 14.
  • Fig. 15 shows a rear door lock control of a motor vehicle.
  • the block 11 comprises as in FIG. 14 the conduit 53 ensuring unlocking by actuation of the interior button 10.
  • a distributor 57 similar to the distributor 22 is mounted in the conduit 20. The inlet of this distributor 57 and one of its outputs are connected to the conduit 20, and its other outlet is connected to the vessel 16, symmetrically with respect to the distributor 22.
  • One end of the distributor 57 is connected by a conduit 58 to a pump 59 with manual actuation, called “child safety", installed for example in the edge from the door.
  • the actuation of the pump 59 thus makes it possible to condemn the lock only vis-à-vis the interior button 10, while the condemnation vis-à-vis the exterior button, 9 is still effected by a key (pump 12) or an interior frieze puller (pump 13).
  • the distributor 22 can also be controlled by an electrically actuated pump 60, as shown in broken lines in FIG. 15.
  • This pump 60 can in particular be common to all the locks of the vehicle and belong to an electric control device for central locking of these locks.
  • Fig. 16 shows a "universal" control for a motor vehicle lock grouping together all the locking functions provided by the circuits of FIGS. 14 and 15 as well as an additional function of "locking without key with the door open".
  • the distributor 54 of FIG. 14 is replaced by a more complex two-position and five-way distributor 61, and an additional three-way distributor 62 is interposed in the conduit 19 between the distributor 22 and the pump 7.
  • the distributor 61 In its stable position shown in FIG. 16, the distributor 61 has a passage 63 which connects all of the pumps 12, 13 and 60, mounted in parallel, to the distributor 22, a passage 64 which connects the vessel 16 to one end of the distributor 62 by a conduit 65, and a blocked outlet 66 connected to an intermediate point of the conduit 65 by means of a check valve 67 directed towards this conduit.
  • a check valve 67 directed towards this conduit.
  • only one passage 68 remains open connecting the pumps 12, 13 and 60 to the outlet 66.
  • the inlet and a first outlet of the distributor 62 are connected to the duct 19, while its second outlet is connected by a duct 69 at the locking end of the distributor 22.
  • a spring 71 permanently biases the distributor 62 towards its illustrated position, in which its inlet communicates with its first outlet.
  • the distributor 61 When the lock 2 is completely locked, the distributor 61 is in its locking authorization position illustrated in FIG. 16: the conduit 65 is connected to the vessel 16, which allows the distributor 62, under the effect of the spring 71, to make the pump 7 communicate directly with the inlet of the distributor 22.
  • the passage 63 allows the pumps 12, 13 and 60 to carry out the locking-unlocking of the lock with respect to the external button 9.
  • FIG. 17 schematically shows a practical embodiment of the circuit of FIG. 16.
  • Block 11 is embodied by a parallelepipedic block in which all the conduits of FIG. 16, four bores receive the four drawers of the distributors 22, 57, 61 and 62, the retaining devices 45A, of the type illustrated in FIG. 13, of the first three and the spring 71 of the fourth, and two cavities for housing the check valves 18 (produced as in FIG. 4 to allow expansion of the liquid) and 67.
  • the vessel 16, the exterior 7 and interior 8 pumps and the jack 5 are connected to the orifices of the corresponding conduits.
  • the corresponding pumps among the pumps 12, 13, 56, 59 and 60, to the orifices of the corresponding conduits, the other orifices being closed at tight seal by plugs (not shown) and the unused distributors being blocked in their direct passage position, which is automatically the case for the distributor 62 and can be obtained for the other three by a simple extension of their stop 51 .
  • a front door control such as that of FIG. 14 or a rear door control such as that of FIG. 15. Since, moreover, the entire control has an indifferent orientation, it can be mounted either in a left door or in a right door. The degree of standardization is therefore very high.
  • Fig. 18 schematically shows a different arrangement of the same block 11.
  • a network of conduits is hollowed out in the upper face of a lower plate 72, and these conduits open only on the lower face of this plate by means of vertical conduits not visible on the drawing.
  • the block also comprises an intermediate plate 73, which also has in its lower face a network of conduits as well as a recess for housing the valve 67.
  • In the upper face of the plate 73 and in the lower face of an upper plate 74 are hollowed out half-cavities whose union defines the bores of the four distributors 22, 57, 61 and 62 as well as a cavity for the valve 18.
  • the block 11 is completed by a gasket 75 interposed with a gasket between the lower 72 and intermediate 73 plates.
  • This gasket is pierced by a series of orifices 76 establishing the desired communications between the conduits of the plate 72 and those of the plate 73. It is therefore sufficient to change the seal 75 to pass, for example, from the command in FIG. 14 to that of FIG. 15, without any plug being necessary for the orifices of the unused conduits.
  • the closure provided by the seal 75 also makes it possible to remove the drawer of unused distributors.
  • Fig. 19 shows a lock 2 in which a pump 56 for indicating the unlocked door is incorporated.
  • the rod 4 which penetrates into a cylindrical socket 79 adjoining the housing 80 of the lock, is hinged on the locking member 3 of the strike 77 hooking hole (not shown).
  • This rod is supported at its end on a rolling membrane 81 whose periphery is clamped between an end shoulder of the sleeve 79 and a closure member 82.
  • the latter is provided with a tube 83 for connecting a flexible tube83 a leading to block 11.
  • the elements 4, 79, 81 and 82 constitute the unlocking cylinder 5.
  • the periphery of the fork 77 constitutes a cam on which rests a finger 83 guided in the housing 80 and biased by a spring 84.
  • On the base of the finger 83 is articulated one end of a lever 85 which oscillates by an intermediate point on an axis 86 of the housing 80 parallel to the axis of rotation 87 of the fork 77.
  • the other end of the lever 85 is simply supported on a closed end of a bellows 88, the other end, open, is fixed to the housing 80 around an orifice 89 thereof.
  • a flexible tube 90 is connected to the orifice 89 and to the block 11, so that the elements 83 to 86 and 8S constitute the pump 56.
  • the finger 23 can of course also be connected to an alarm, for example a light, of an improperly closed door.
  • Fig. 20 shows an example of hydraulic actuation devices.
  • the two locking pumps 12 and 13 are bellows connected respectively to the cylinder of the key 14 and to the pull tab 15, since they do not have to withstand significant pressures, being only intended to move the drawers of the locking distributors.
  • the unlocking pump 7 is of the rolling membrane type, clearly more robust, because this pump must transmit to the jack 5 the force necessary for the movement of the locking member 3 of the lock.
