Definitions
- Anti-theft device for two wheels and more particularly for motorcycles.
- the present invention relates to an antitheft device for two wheels and more particularly for motorcycles.
- Another anti-theft device is called a disk block and, as its name suggests, it locks the disc of the two-wheeled vehicle. It can be attached to the front or rear wheel of the bike. This device has the advantage of its compactness but on the other hand it can not be attached to an anchor point which does not exclude theft by driving of the motorcycle. In addition, it is very discreet and is unfortunately often forgotten by the owner of the vehicle. This oversight usually causes a lot of damage (warping, destruction of brake caliper) because the wheel can make a full turn before it locks. Moreover, it does not offer a sufficiently effective and satisfactory resistance and security. Indeed, it only takes 15 seconds to 1 minute 30 to the specialists to neutralize it, a time much too short for deter thieves. It is obvious that the number of thefts decreases with the time of resistance of the antitheft to the kidnappers.
- the transmission chain is an essential element of a two-wheeled vehicle such as a motorcycle. Also the inventors are interested in this element especially in the design of their antitheft device. Indeed, no antitheft on the market blocks the chain of transmission.
- This clamp therefore comprises two clamping jaws articulated in the manner of a pair of scissors and extended beyond the axis of articulation by two branches. These two flat branches, in the closed position of the clamp, extend against one another and in the open position move away from each other to spread the clamping jaws, in the manner of a pair of scissors substantially in the form of X.
- each branch has a matched light so that in the closed position of the clamp, we can engage the rod of a padlock through the branches and thus block the articulation of the antitheft device.
- a clamp has a major drawback in that such a device can easily be removed by simply cutting the padlock. It is therefore easy to understand that such a lock has not been successful.
- the present invention therefore has the main purpose of providing a simple antitheft device to use and high reliability.
- the present invention relates to an antitheft device for a two-wheeled vehicle, in particular a motorcycle, consisting of a clamp comprising two clamping jaws articulated between an opening position of the clamp and a closing position of said clamp, said two clamping jaws being arranged for, in the closed position of the clamp, defining a space in which is a housing section of the transmission chain of the vehicle and the ring bearing, said space being shaped so that, in the closed position, said clamp is retained on the transmission chain by said transmission chain, locking means of the antitheft device in place on a vehicle being further provided, characterized in that the clamp has in addition to the two clamping jaws, two branches extending beyond the axis of articulation of the clamp and defining, in the closed position of the clamp, a space between them in which the locking means are arranged to be lockably / releasably housed, to block the articulation of the clamp and prevent opening thereof, when the antitheft device is in place on a vehicle.
- the antitheft device according to the invention is of simple use since it is sufficient to open the clamp to place it on a section of the transmission chain of a motorcycle and a section of the crown, then closing said clamp to hold it in place on said chain and said ring, the locking means blocking the opening of said clamp.
- the space defined between the clamping jaws of the clamp has a first portion in which is housed a section of the transmission chain and a smaller dimension portion being housed under the transmission chain at the crown.
- the inner face of each clamping jaw has a groove which, when the jaws are facing one another, defines the first part of the space in which is accommodable the transmission chain while the end of the clamping jaws defines the second part of said space, this end forming therefore a return which, when the clamp is mounted on the transmission chain and the crown, is housed under said transmission chain at the crown.
- the locking means of the device according to the invention are arranged to be housed in a lockable / unlockable manner between the two branches of the clamp.
- the locking means consist in particular of a bar that can be placed between the two branches of the clamp opposite the gap between the clamping jaws, in which a section of the transmission chain is housed and a part of the crown, above the pivot axis and parallel to the latter.
- the locking means that can be accommodated in the space between the branches of the clamp comprise locking / locking members cooperating with complementary members formed on the clamp so that when they are accommodated in said space between the two branches of the clamp, these locking / locking members are not or hardly accessible and thus, the forcing or the fracture of the locking means of the clamp are extremely difficult or even impossible.
- Said bar preferably has a stepped lower face, the end of the bar engaging first between the branches of the clamp being recessed relative to said clamp, leaving a space, while the other end of the bar rests against the clamp, the bar, carrying at its end, a lock and in the extension of said lock, as locking / locking member, a locking rod for locking said bar on the clamp, by cooperation of a rib, as a complementary member, extending transversely between the arms of the clamp and at least one lug formed on the locking rod. Under the effect of the actuation of the lock, the rod is rotated which causes the positioning of the pin of the rod projecting behind said rib of the clamp.
- one of the clamping jaws has a radially projecting portion provided with a pin intended to project inwardly of the clamp, substantially perpendicular to the axis of pivoting of said clamp and suitable for lodging in a light of the crown carrying the transmission chain.
- the clamp is held in the closed position by an elastic return means such as a spring, so that it is sufficient to exert pressure on the branches of the clamp to bring them together so as to spread the clamping jaws , releasing this pressure bringing the clamping jaws facing each other in the closed position under the effect of the elastic return means while the branches depart again.
- an elastic return means such as a spring
- said antitheft device is equipped with a system for alerting persons that a motorcycle theft is occurring.
- This system can be, for example, an electronic warning system, an at least auditory and / or visual alarm inserted in the device and which is deactivated when the device is unlocked appropriately.
- a system for alerting persons that a motorcycle theft is occurring can be, for example, an electronic warning system, an at least auditory and / or visual alarm inserted in the device and which is deactivated when the device is unlocked appropriately.
- a certain sound level about 110 dB
- a visual alarm such as flashing lights
- Figure 1 is a front perspective view of an embodiment of an antitheft device according to the invention.
- Figure 2 is a side view of the device of Figure 1;
- Figure 3 is a view of the other side of the device of Figure 1;
- Figure 4 is a top view of the device of Figure 1;
- Figure 5 is a top view of the clamp of the device of Figure 1;
- Figure 6 is a view from below of the locking means of the device of Figure 1;
- Figure 7 is a top view of the device of Figure 1 at the time of assembly of the locking means on the clamp;
- Figure 8 is a front perspective view of the clamp of the device according to Figure 1 in the open position
- Figure 9 is a front perspective view of the device of Figure 1 mounted on a transmission chain and a motorcycle crown.
- the antitheft device consists of a clamp A having two clamping jaws 1, 2 and two branches 10, 20, pivoting about an axis 3 and articulated by a return spring 4. Said clamping jaws 1, 2 can thus pivot and open, in the manner of a hair clip, releasing a space 5 in which can accommodate a section of the transmission chain 6 and a portion of the ring 13 carrying said chain 6 while that the branches 10, 20 come closer to each other.
- These two jaws 1, 2 are thus arranged to form in the closed position of the clamp A, the space 5 to accommodate between them a section of the transmission chain 6 and a portion of the crown 13 as can be seen at Figure 9.
- the space 5 is further shaped to accommodate a section of the transmission chain 6 and a portion of the ring 13 but also so that said clamp A is retained on the transmission chain 6 by said transmission chain 6.
- this space 5 has a first portion 5a in which is housed a section of the transmission chain 6 and a portion 5b of smaller dimension housed under the transmission chain 6 at the crown 13.
- each clamping jaw 1, 2 preferably has a groove 7 which, when the jaws 1, 2 are facing one another, define the first part 5a of the space in which is the transmission chain 6 while the end 8 of the clamping jaws 1, 2 defines the second part 5b of the space 5.
- This end 8 therefore forms a return which, when the clamp A is mounted on a section of the transmission chain 6 and the ring 13, is housed under said transmission chain 6 preventing the withdrawal of the clamp A.
- the axis of pivoting 3 or articulation of the clamp A is a conventional axis consisting of a forged steel rod passing through orifices provided in each of the branches 10, 20.
- the pivoting of the branches by bringing the ends together opposite to the clamping jaws 1, 2 causes an opening of the clamp A and a spacing of the clamping jaws 1, 2.
- the opening of the jaws 1, 2 then allows the placement of the anti-theft device on the transmission chain 6 or withdrawal thereof .
- the clamp A is designed forged steel, a material that offers good hardness and good strength while minimizing the weight.
- the main objectives of the present invention are the reliability and the inviolability of this lock.
- one of the clamping jaws 1, 2 has a radially projecting portion 8a provided with a pin 9 intended to come into protrusion inwardly of the clamp A, substantially perpendicular to the pivot axis
- This pin 9 is intended to be housed in one of the lights 11 of the ring 13 carrying the transmission chain 6.
- the antitheft device can not progress to the maximum than the length of the light 11 because the pin 9 abuts against one of the ends of said light 11.
- Said anti-theft device also comprises locking means B consisting in particular of a bar 14 which is placed in the space 50 between the two branches 10, 20 of the clamp A opposite space 5, above the pivot axis 3 and parallel to the latter.
- This bar 14 is arranged to engage between the branches 10, 20 of the clamp A and so that once engaged on said clamp A, the upper part of said bar 14 is in alignment with the ends of the branches 10, 20 of the clamp A as can be seen in FIG.
- the bar 14 when said bar 14 is in place in the lock, it prevents the opening of the jaws 1, 2 by pivoting about the axis 3 described above.
- the bar 14 further comprises locking / locking members of said bar on the clamp thus allowing the locking of the clamp A.
- the lower portion of said bar 14 is stepped, that is to say that the end 14a of the bar 14 engaging first between the legs 10, 20 of the clamp A is set back relative to the clamp A while the other end 14b of the bar 14 rests against the clamp A.
- This bar 14 also carries at one of its ends 14b, a lock 15 housed back from the surface of the bar 14 to provide maximum safety especially in terms of drilling, sawing and cutting.
- the locking means B further comprise housed in the bar 14 and in the extension of the lock 15, a locking rod 16 for locking said bar 14 on the clamp A.
- This locking rod 16 is a metal rod containing the minus a lug 17 protruding. Said locking rod is rotated at the same time as the rotation of the key in the lock 15.
- this locking rod 16 is an unmachined cylinder housed in part 14b (hidden stem) and then machined with at least one plate in part 14a.
- the cylinder in this portion 14a is therefore in the form of a half-cylinder forming a lug 17 and provided with a notch 16a.
- the lock 15 when inserting the bar 14 on the clamp A between the branches 10, 20, the lock 15 must be in the open or unlocked position so that the pin 17 is erased in the bar 14 so as to pass over the rib 18 has between the branches 10, 20 of the clamp A. Then the bar 14 by its projecting lower part abuts against said rib 18. The bar 14 is then in place on the clamp and the lock is actuated 15 so that the lug 17 of the locking rod 16 is projecting behind said rib 18, preventing any removal of the bar 14, thereby locking the establishment of the antitheft device.
- the lock used has a mechanism known to those skilled in the art. It is for example blocked by pins and has drive members of the cylinder forming the locking rod 16. -
