Definitions
- Anti-theft device for blocking the handbrake of a motor vehicle
- the present invention relates to an anti-theft device for blocking the handbrake of a vehicle comprising a case in which is housed the end of the brake comprising the handbrake release button, and a key push barrel comprising a blocking element which, when the barrel is actuated by the key, prevents the release button from being pressed.
- WO-A-84/00020 describes a device which is fixed on the handbrake and which comprises a locking system by rings whose opening is done by turning the rings so as to display a determined number.
- Such a sophisticated device is expensive, can be breached - quickly by testing different combinations of numbers and runs the well-known risk of forgetting the combination of numbers if the owner of the vehicle has not taken care to keep it on him.
- DE-A-3,816,606 describes a device actuable by key which fits on the handbrake and prevents access to the push button when the device is locked. This device, unlike the previous one, is not attached to the hand brake, and therefore has the drawback of being able to be lost easily.
- Patent DE-C-817.559 describes an anti-theft device actuated by a key and which is an integral part of the handbrake, the locking system being produced by a blocking element coming into a housing of the brake case at hand when the key is pressed. Unless to completely redo the handbrake, such a device is, of course, not adaptable to existing vehicles.
- the object of the invention is therefore to produce an anti-theft device by blocking the hand brake which is inexpensive, and which can nevertheless be mounted without calling on a specialist.
- Another object of the invention is to provide an anti-theft device by blocking the hand brake which can be adapted to all existing vehicles.
- the object of the invention is therefore an anti-theft device for blocking the handbrake of a vehicle of the type which includes the handbrake and a barrel actuated by a key, in which the device is a separate assembly from the brake. hand and can be adapted to any existing model, the case being made integral with the hand brake by a fixing means of the bonding type and turning screws so that the device can be installed easily without calling on a specialist.
- Another object of the invention is an anti-theft device as defined above in which the axis of the barrel is parallel to the axis of the handbrake but moved relative thereto, the depression of the barrel in the unlocked position causing depression of the handbrake of the push button by means of a latch, the ⁇ offset 1'axe of the barrel relative to 1'axe handbrake avoiding to reach the button and proceed to the release of hand brake by drilling the barrel.
- Yet another object of the invention is an anti-theft device of the barrel type in which the axis of the barrel is perpendicular to the axis of the handbrake and the pushbutton of the handbrake has a groove located at the right of the blocking element actuated by the barrel when the handbrake is locked, so as to that the actuation of the key causes the entry of the blocking element in the groove and thus prevents
- This embodiment makes it possible to adapt the anti-theft device to a hand brake that does not have sufficient clearance to be able to maneuver it with a device having a barrel whose axis is the same or parallel to the axis of the brake. hand.
- the inside of the anti-theft device case has a shape allowing it to be adapted either to hand brakes of circular section, or to hand brakes of rectangular section, that is to say to all the types currently existing on the market.
- the device of the invention in addition to being able to be easily adapted to existing hand brakes without calling on a specialist, constitutes a safety element preventing the vehicle from being able to move unexpectedly when children being in the vehicle stop, try to manipulate the handbrake.
- FIG. 1 represents a first embodiment of the anti-theft device of the present invention
- FIGS. 2a and 2b are sectional views of the device shown in Figure 1
- Figure 3 shows a variant of the embodiment of Figure 1 using a self-locking lock
- Figure 4 is a sectional view of the device according to the embodiment illustrated in Figure 3
- Figure 5 shows a second embodiment of the anti-theft device of the invention in which the axis of the barrel is moved relative to the axis of the handbrake
- Figures 6 and 7 show a third embodiment of the anti-theft device of the invention in which the axis of the barrel is perpendicular to the axis of the handbrake
- Figure 6 being a sectional view and Figure 7 a view overall
- FIG. 8 shows the section of the device according to the invention making it possible to adapt it to any type of hand brake
- FIG. 9 shows a fourth embodiment of the anti-theft device of the invention.
- the anti-theft device comprises a key barrel 10 with its spring 12, arranged in a barrel body or case (14).
- the barrel body (14) is placed in the front part of a cylinder 16 and is fixed to said cylinder 16 by two opposite pins 18 and 20 so as to prevent any movement: of the barrel body 14 in the cylinder 16.
- the key (not shown) has a position that does not vary over time, either in the locked position or in the unlocked position.
- a closing latch 22 is fixed to the barrel 10 by a welded screw 24 so as to avoid any loosening.
- the latch 22 is movable relative to the barrel body.
- the rear part 26 of the cylinder forming the body of the device comprises a groove or housing 28 in which the latch is received when the key has been turned to the locking position.
- the cylinder has a groove 30 at its part opposite to the housing 28, this groove extending over a certain length unlike the housing 28 provided only for the passage of the protruding part 22-1 of the latch 22. This is clearly visible in FIGS. 2a and 2b which respectively represent sections AA and BB of the device of FIG. 1.
- FIG. 2a and 2b respectively represent sections AA and BB of the device of FIG. 1.
- Figure 2a shows, in turn, the groove or obviously of the cylinder part 26, in which is the protrusion 22-1 of the latch 22 when the device is unlocked.
- the hand brake 32 terminated at its end by the release button 34 and its return spring 36, is fitted into the rear part 26 of the cylinder forming the body of the device according to the invention.
- the rear part 26 can be fixed to the handbrake by a weld bead 38 or preferably glued and fixed permanently with the aid of a turning screw as will be seen later.
- a groove 40 is used to attach (using a collar) the original handbrake lining.
- the driver of the vehicle wishes to release the handbrake, he actuates the barrel 10 with his key and thus allows the rotation of the latch 22, and releases the protuberance 22-1 from its housing 28. In the unlocked position, the protuberance 22-1 is then placed in the groove 30. The depression of the barrel 10 is therefore possible since the latch 22 can move in the groove 30. The depression of the barrel 10 causes the depression of the release button 34 and therefore the release of the hand brake.
- the two parts 16 and 26 of the cylinder of the device are initially distinct so as to be able to mount the body of the barrel 14 provided with its latch 22 in its place. Once this assembly has been carried out, the assembly of the two cylinder parts is made by a weld bead on the entire circumference of their junction 42.
- FIG. 3 A variant of the embodiment of FIG. 1 using a self-locking lock is illustrated in FIG. 3.
- the barrel 10 is terminated by a part 13 of smaller diameter, comprising an edge 13-1 of shape rectangular.
- the end of the body of the barrel 14 has a circular opening having a groove 14-1 as can be seen in Figure 4 showing the section of the device according to the section AA of Figure 3.
- the edge 13-1 is in the high position as illustrated in figure 3.
- the part 13 of the barrel turns 180 ° and the edge 13-1 is in low position opposite of the groove 14-1.
- the barrel can then be depressed and cause the release of the release button 34 so as to release the handbrake.
- the anti-theft device illustrated in FIGS. 1 and 3 is effective against theft of the vehicle with which it equips the handbrake, it is still possible, coming from an experienced thief, to pierce the barrel of the device to reach the button. release and release the handbrake.
- the axis of the barrel 42 is offset relative to the axis of the handbrake.
- the closing latch 22 In the locked position, the closing latch 22 has its protuberance 22-1 in the housing 28 formed in the body 36 of the device (which is no longer a cylinder as in Figure 1).
- the latch protrusion 22-1 In the unlocked position, the latch protrusion 22-1 is in the low position as illustrated in the figure, and is therefore no longer blocked.
- the depression of the barrel 10 then causes the displacement of the latch 22 which comes to bear on the release button 34 of the handbrake and the depression of the release button 44 enabling the handbrake to be released.
- the assembly of the device of Figure 5 on a hand brake is done without problem, in the same simple way as the assembly of the device of Figure 1, by gluing and screw turning, without requiring a specialist.
- the release button is assembled on the handbrake body by a threaded rod 48 shown in dotted lines in FIG. 6.
- the conventional release button is replaced by a button comprising a groove 52.
- the anti-theft device illustrated in section in FIG. 6 consists of a cylinder fitting onto the handbrake as in the previous embodiments, provided with a part 56 perpendicular to the of the handbrake.
- the part 56 comprises a barrel 58 actuated by a key.
- the barrel has at its end, a bolt 60 which, when the barrel is pressed in the closed position by operating the key, enters the groove 52 of the release button 50. In this position, it is therefore impossible to cause the depression button 50 to enable the handbrake to be released.
- Figure 7 shows the anti-theft device according to the embodiment of Figure 6 when mounted on the handbrake. It can be seen that even if there is little space between the end of the release button 50 and the linings or the gear lever, the anti-theft device does not provide any additional space hindering the operation of the handbrake.
- the barrel 58 and its key being placed upwards, it is extremely easy to carry out the manipulation of the handbrake. Mounting the anti-theft device on the vehicle's handbrake is very easy without the need for a specialist.
- the body or cylinder 54 of the device is fitted onto the hand brake 62 after the latter and the interior of the cylinder have been covered with glue. This adhesive must be very strong in order to resist any attempt to separate the anti-theft device from the handbrake.
- the hand brakes mounted on commercial motor cars are of two types, once the lining, generally made of plastic, has been removed.
- the handbrake body In a first type, the handbrake body has a circular section with a diameter of 20.2 mm.
- the handbrake body In the second type, the handbrake body has a rectangular section, the largest dimension of which is 21 mm.
- the anti-theft device makes it possible to be adapted to one or the other of the two types of hand brakes mentioned above.
- Figure 8 which shows the section of an anti-theft device
- the section of the body of the device in which fits the hand brake is in the form of a circle 66 having two flat parts 68 diametrically opposite.
- the circle 66 has a diameter slightly greater than the diameter of the hand brakes of the first type (20.2 mm) so that the device can easily adapt to the hand brake.
- the two flat parts 68 are spaced a length slightly greater than 21 mm so as to be able to adapt the anti-theft device also on hand brakes of the second type and whose section 70 is rectangular.
- the two flat parts 68 are equivalent to two notches for receiving the rectangular hand brake.
- the anti-theft device is mounted on a hand brake of rectangular section, as is the case illustrated in FIG. 8, it is necessary to provide two shims in the form of portions of a circle which are placed between the hand brake 70 in the form rectangular and the inner walls of the cylindrical body of the device in the form of an arc of a circle 66.
- the two shims are fixed in their respective locations by gluing and also by screw-cutting.
- a buttonhole-shaped recess 72 must be provided in the block so as to be able to easily place the turning screw which comes to bite on the handbrake 70.
- the device is in two parts.
- a first part 74 which is fixed on the hand brake in the same way as in the previous embodiments, has the shape of a cylinder which fits at the end of the hand brake so as to allow it to protrude, after fixing with the handbrake, only the release button 76.
- This part 74 the diameter of which is greater at the end where the button 76 is located, comprises a barrel 78 identical to the barrel 58 of the device of FIG. 6, it is ie comprising a bolt 80 projected downwards when the barrel 78 is actuated by a key.
- the second part 82 has an opening of slightly larger shape than the bolt 80 and placed in line with the bolt when the second part 82 is inserted in the first part 74.
- the actuation of the key and therefore of the barrel 78 therefore has the effect to introduce the bolt 80 into the opening of the second nested part and to prohibit access to the release button 76 of the handbrake, thus preventing the unlocking of the latter.
- the anti-theft device according to the invention can be made of metal such as steel, brass, aluminum., With a covering of plastic material or all of plastic material such as a hard polyamide resin.
- the external shape of the device can be arbitrary, but it is preferable for it to be in the form of a handle adapted to the hand such as the shape of the embodiment illustrated in FIG. 5.
- the main advantage of the device of the invention is that it is simple and inexpensive, is easy to assemble, by gluing and turning screws without requiring a modification of the handbrake, therefore without having to call in a specialist.
