Definitions

• the purpose of the device according to the invention is to protect any vehicle against theft by means of electrical and mechanical protection.
• the mechanical protection then supplements the electrical protection because this latter can possibly be neutralized by an informed person.
• This protection is ensured by non-return valves mounted in series in the braking circuit. During the ⁇ on- authorized use of the vehicle, even if the electrical circuit is restored, at the first request of the brakes the vehicle will remain permanently blocked on site; only the rotation of the control key can release the brake lock.
• control parts - are linked by threads without effective tightening thereof.
• This device comprises, in a manner known per se: a cylinder lock ensuring the movement of at least one valve of a hydraulic and / or pneumatic circuit for finger ⁇ swimming the vehicles after implementation of the device, associated or no to a double electric contactor •• open-closed ⁇ ensuring protection on the derr.arreur and ignition control circuit as well as putting an alarm on standby.
• the valve control system consists of a drawer in which said valves are incorporated and a groove for circulation of the fluid bringing the inlet and outlet of the device into relation, thereby avoiding inadvertent blockages caused by insufficient rotation of the key # because the ball is no longer in front of its seat.
• valves consist of a ball disposed in a radial housing of the drawer pushed by a spring contained in said housing to come to bear on its seat, attached or not integral with the inlet duct of the block containing the drawer; sealing is ensured by seals arranged on each side of the valve-groove assembly mounted in the block, or mounted on the drawer.
• the drawer is provided with i ⁇ dexing means in a working position (anti-theft function), and in one or more rest position (road position) thus avoiding any risk of untimely blocking caused by vibrations or rotation insufficient key.
• housings receiving the ball spring assemblies are connected to the circulation groove by leakage conduits.
• the drawer is rotary and is connected by means of coupling in rotation to the barrel of the lock and the circulation groove is constituted by a groove arranged in the transverse plane of the valve.
• the drawer is linear, its movement is effected by means of two inclined planes kept in contact by a spring, or by means of a screw-nut system from a lock arranged axially.
• This translational control is effected by cam or excen ⁇ stick with the lock arranged perpendicular to the axis of the drawer.
• the valves are radially mounted and open into a circulation groove which connects the entry and exit of the anti-theft device in the road position.
• the ball comes to its seat, which causes the brakes to lock when the first action is taken on the pedal.
• Position indexing is also provided (ball and bowl for example). In all cases, the electrical part can only operate if the ball is no longer in its seat thanks to two sliding pushers resting in their respective bowls, or other similar systems.
• a stroke limiter is also provided in order to avoid turning the barrel indefinitely and to position the key in the road and flight positions.
• the lock will be locked axially and in rotation by a ring and a pin embedded in the block containing the drawer, or by other locking means.
• One piece is in movement with the barrel of the lock. All the connections are made directly on the bfoc of the device.
• a safety binding avoiding deactivation of the input circuits to the marten cylinder and the output mechanism circuits towards the brakes is carried out using connectors provided with an operating head cassa ⁇ te ⁇ >) security by rupture beyond a defined effort thus making the whole unassemblable.
• a grounded electrical wire is fixed which supplies the electrical contactor-controlling the ignition and the auxiliary alarm.
• This device is intended for the control of a certain number of organs with the corresponding number of valves.
• the inlet and outlet holes can be asymmetrical for a more reduced construction of the device.
• the device can be provided with outputs and inputs parallel to the axis of the drawer, the electrical contactor is then perpendicular to the axis of the drawer.
• This invention can equip all vehicles, it works equally well on hydraulic brakes, on the clutch or parking brakes of heavy goods vehicles. The main characteristics and obvious advantages of this device will emerge from the description which follows; the accompanying drawings are given as an indication but in no way limita ⁇ tive as to the final embodiment.
• Figure 1 shows the block diagram of the assembly connected to the braking circuit, g
• the block (1) is connected on the one hand with the master cylinder (28) connected to the pedal (29) by the lines
• the device is actuated by a key (13) in a barrel (14).
• Figure 2 is an exploded perspective view of the lock according to a first embodiment.
• 1Q Figure 3 is a sectional view of the block (1) at the entrance (22) where the seat
• FIG. 4 represents a plan view of the rotary drawer (2) comprising a groove (19) for coupling for controlling the arotatio ⁇ of the titrator (2).
• Three grooves (34) are used to house the seals (1o).
• Two circulation grooves (21) are used for the free circulation of the brake fluid when the ball (8) is no longer on its seat (?).
• Indexing cups (20) are also machined in the drawer (2) where a ball pushed by a spring (assembly 16) maintains the chosen position.
• Figure 5 is a sectional view along AA of Figure 4 of the drawer (2) where the housing (35) of the spring (9) and the ball (8) is in communication with the circulation groove (21) 0 ar conduits (2 i ).
• Figure 6 is a sectional view BB of Figure 4 of the drawer (2) which are shown the indexing cups (20).
• FIG. 7 shows the drawer (2) in the block (1) in the road position, position where the ball (8) no longer rests on its seat.
• FIG. 8 represents a plan view of the linear drawer (36) in the block (37). In this figure are shown the valves (46), the grooves (38) for circulation on the generatrices of the drawer (36), the grooves which receive the seals and the position indexings (39).
• the rotational stop of the drawer (36) is effected by means of a groove (40) in the drawer and guide means such as screw-key, stud screw, pin (50) in the figure.
• the inclined plane (41) is used for the translational control of the drawer (36) thanks to the inclined plane (42) 0 fixed on the barrel (43) of the lock (44).
• a spring (45) ensures the contact of the two inclined planes (41) and (42) and the return to the position of the drawer (36).
• FIG. 9 represents a view in 1/2 plane and in 1/2 section, a brittle fitting (27) where the groove (49) is a breaking groove so that this fitting once assembled and locked, the broken hexagon is removable only very difficult.
• FIG. 10 represents another embodiment of the --calich- * connection, in 1/2 view and in 1/2 section where the initiation of rupture is effected by calibrated holes (47) perpendicular to the axis of rotation of the fitting.
• FIG. 1 when the key (13) is in position (I), the electric contactor can allow the vehicle to start (as well as the alarm cut-off), the braking circuit is normal, i.e. the ebb and flow of brake fluid is allowed.
• the various circuits are sealed by O-rings compatible with the brake fluid.
• a cylindrical pusherM sliding axially commanding the opening or closing of the electrical contactor (25) during the rotation of the key (13) in position I or II by means of cups (48).
• a cylindrical pin (3) Fixed on the barrel (14) of the lock (5), a cylindrical pin (3) is provided with a part (18) intended to couple with the complementary part (19) machined in the rotary drawer (2).
• a pin (15) serves as a stop on the part (18) of the post, it is elf who can " define the position of the barrel of the lock to remove the key. Inserted in the block (î) a pin (15) limit the rotation of the barrel abutting on the tenon (3).
• braking is done by compressed air, which a distributor controls via the brake pedal.
• compressed air is sent to the parking brake, which is released.
• the truck can roll.
• the device must prevent air from reaching the parking brake air bottles. So just reverse the inputs with the outputs of the device.
