Definitions

• the invention concerns a removable antitheft device for vehicles steered with a handle-bar, as set forth in the main claim.
• the invention consists of a removable antitheft device which, when fitted to a vehicle such as a bicycle, motorscooter, motorcycle or any vehicle steered with a handle-bar, and after actuation of one of the control levers positioned on the handle-bar of the vehicle, clamps that control lever in the actuation position and prevents its release.
• the antitheft device is employed to clamp directly at least one wheel of the vehicle.
• These means can be incorporated in the vehicle itself or else can be external independent elements such as chains with a lock or steel bows to clamp the wheels and/or to secure the vehicle to an external body.
• the means incorporated in the vehicle generally do not act on the wheels and are therefore unable to prevent the vehicle being lifted and removed, whereas the use of external means, which are often bulky and heavy, is conditioned by the availability of means to which the vehicle can be secured and by the resistance of the means to stresses.
• antitheft means are often well known to any ill-intentioned person interested in removing the vehicle, for such a person can readily acquire the techniques and means suitable for neutralising such antitheft means.
• This invention concerns a removable antitheft device for vehicles steered by a handle-bar, the device being simple and economical and being able to clamp a movable part of the vehicle, in particular, one of the control levers positioned on the handle-bar.
• this antitheft device has a conformation and a possible colouring which are visible, and this fact has or may have a dissuasive effect on the ill-intentioned person.
• the removable antitheft device comprises a body consisting of a first part and a second part hinged on each other to form a gripper, each of which parts includes a semi -circular hollow, and a C-shaped element or bow.
• a gripper each of which parts includes a semi -circular hollow, and a C-shaped element or bow.
• the two parts of the body are solidly associated, by means of their semi-circular hollowed portions, with a hand grip of the handle-bar of the vehicle and, by means of the bow, clamp the corresponding control lever, whether that lever controls the brake or the clutch.
• the first part of the body comprises a hollow, within which a first arm of the bow can slide axially to an end-of- run position, and reversible closure means able to clamp that first arm in a closure position; the second part of the body includes an open space cooperating with the second arm of the bow.
• the first arm of the bow is inserted into the hollow made in the first part of the body towards the travel of minimum extent, while the second arm of the bow is inserted into an open space of the second part of the body and possibly into a second hollow provided in the protrusion belonging to the first part of the body, thus connecting rigidly together the first and second parts of the body and thereby fixing the antitheft device to the hand grip or to a stationary part of the vehicle; at the same time the traversing of the bow clamps in the actuation position a control lever or else a movable part of the vehicle.
• the actuation of the bow into the position for clamping the control lever takes place by hand after the two parts of the body have been associated in their closed position on the hand grip of the handle-bar.
• the actuation of the bow into the clamping position is functionally and kinematically associated with closure of the two parts of the body on the hand grip of the handle-bar.
• the removable antitheft device is employed to clamp directly one of the wheels of the vehicle by means of the bow, the body being secured to the fork or to another element of the frame of the vehicle.

• Fig.l shows a side view of a removable antitheft device in the closed position, the device comprising a body 3 and a C- shaped element or bow 13 which can be moved in relation to the body 3.
• the body 3 and bow 13 are advantageously made of a metal.
• Fig.4 shows a partial three-dimensional view of a handle- bar of a vehicle in which the antitheft device of Fig.l is applied to a control lever 1, which is preferably, but not necessarily, one of the levers controlling the brakes.
• the control lever 1, a hand grip 2, the body 3 and reversible closure means 5 able to fix the body 3 to the hand grip 2 in correspondence with the control lever 1, which is clamped at the same time between the body 3 and the bow 13.
• the hand grip 2 is preferably, but not necessarily, that of the accelerator; if the vehicle is equipped with clutch means, the control lever 1 which is clamped may be that of the braking equipment or that of the clutch.
• Fig.5 shows a three-dimensional view of the antitheft device of Fig.4 in the open position, wherein the hand grip 2 and the control lever 1 have been shown with lines of dashes for greater clarity of the representation.
• the body 3 comprises a first part 11 and a second part 12, which are hinged to each other to form a gripper, the second part 12 being able to be moved about a pivot 14 solidly fixed to the first part 11.
• the first and second parts 11, 12 of the body 3 contain respective semi-circular hollows 17 and 18, which enable the antitheft device to be secured to the hand grip 2 of the vehicle; these two parts 11, 12 of the body 3 are rigidly connected together by the bow 13 even if they are not perfectly in contact with each other, thus making it possible to use an antitheft device according to the invention even if the hand grips of that vehicle have a diameter which does not coincide exactly than that of the semi-circular hollows 17 and 18 contained in the two parts 11, 12 of the body 3.
• At least one of the semi-circular hollows 17, 18 cooperates with a resiliently deformable element 23, which adapts itself to the hand grip 2 when the two parts 11, 12 are closed together during the step of clamping the hand grip 2.
• the resiliently deformable element 23 is solidly associated with the second part 12 of the body 3, defines the semi-circular hollow 18 thereof and cooperates with an inner spring 24.
• at least one of the semi-circular hollows 17, 18 instead of the resiliently deformable element 23 or in cooperation therewith, at least one of the semi-circular hollows 17, 18 cooperates with a removable insert 30 which has the function of reducing the thickness; this fact enables the antitheft device to be used in cooperation with hand grips 2 of a modest diameter.
• a first arm 15 of the bow 13 slides in a first hollow 8 provided in the first part 11 of the body 3.
• the first arm 15 is advantageously, but not necessarily, longer than a second arm 16 of the bow 13.
• the second arm 16 of the bow 13 is inserted into an empty space 7 provided in the second part 12 of the body 3 and into a second hollow 9 provided in a protrusion 10 associated with the first part 11 of the body 3.
• the protrusion 10 does not include the second hollow 9, and the second arm 16, in the closed condition, cooperates only with the empty space 7.
• the empty space 7 provided in the second part 12 of the body 3 is preferably, but not necessarily, an open space conformed as an overturned " ⁇ " and closed at its upper end by a plate 29.
• the space 7 consists of a hole provided frontally in the second part 12 of the body 3.
• actuation means of a manual type which comprise a pair of knobs 21 or equivalent means, which are fixed to the first arm 15, able to move in the first hollow 8, of the bow 13 and which emerge from the body 3 through a pair of third slots 20.
• the bow 13 is operated by hand, thus eliminating the knobs 21 and the corresponding slots 20.
• the means operating the bow 13 comprise a carriage means analogous to that used to cock fire arms.
• the first arm 15 of the bow 13 includes at its front end an extension 4 bearing a plurality of teeth or equivalent means, which are able to be momentarily gripped by clamping means associated with the reversible closure means 5.
• This plurality of teeth makes possible the definition of a plurality of intermediate positions of the bow 13 between an open position of greatest extent and a closure position of minimum extent, depending on the extent of the travel of the control lever 1.
• the clamping means comprise a catch 19 and can be disengaged from the teeth by a key or another functionally equivalent means.
• Figs .6 to 8 show a particular embodiment of the invention in which the axial traversing of the bow 13 from the release position to the clamping position and viceversa is associated kinematically with the closure/opening of the two parts 11, 12 of the body 3.
• the rotation of the second part 12 about the pivot 14 entails the traversing of the bow 13.
• the bow 13 is associated by a kinematic chain with the second part 12 of the body 3, this kinematic chain comprising in this example a slotted link 25 which acts on the first arm 15 of the bow 13.
• the first arm 15 of the bow 13 includes a pin 21 cooperating with a first slot 22 provided in the first part 11 of the body 3 and with a second slot 28 associated with the second part 12 of the body 3.
• the first part 11 includes in cooperation with the bow 13 an abutment element 26 with which the control lever 1 cooperates during the step of closure of the antitheft device according to the invention. So as to adapt the dimensions of the containing and clamping seating defined by the bow 13 and by the body 3 in the closure position, the abutment element 26 can be moved parallel to the first and second arms 15, 16 of the bow 13 and cooperates with a screw adjustment means 27 associated with the first part 11 of the body 3.
• This screw adjustment means 27 is associated with the semi-circular hollow 17 in the first part 11 and is accessible only when the antitheft device according to the invention is not associated with the hand grip 2 of the handle-bar .
• the catch 19 of the clamping means associated with the reversible closure means 5 cooperates with teeth located in a coordinated pos ition on an extension 104 solidly connected to the second part 12 of the body 3.
• a covering element 6 is associated with the bow 13 and is advantageously ⁇ -shaped and has an elongate shape and an inner profile complementary to that of the outer edge of the control lever 1.
• This covering element 6 prevents an ill-intentioned person from breaking the control lever 1 at the bow 13 and from withdrawing the bow 13 from the remaining stub of the control lever 1, thus neutralising at least partly the antitheft device.
• the bow 13 is released from the body 3; the first and second parts 11, 12 of the body 3 are disengaged from each other and are brought to the open position.
• the control lever 1 is then inserted into the bow 13 and the semi-circular hollow 17 of the first part 11 of the body 3 is rested on the hand grip 2, and the second part 12 of the body 3 is then rotated until the semi-circular hollow 18 in the second part 12 is rested on the hand grip 2.
• the bow 13 is now traversed automatically or is traversed by manual actuation means 21 into the first hollow 8 in the first part 11 of the body 3 and is clamped by the reversible closure means 5, thus clamping the control lever 1 in the actuation position and connecting together the first and second parts 11, 12 of the body 3 so as to fix the latter to the hand grip 2.
• the control lever 1 is preferably actuated before the bow 13 enters the body 3.
• the removal of the bow 13 from the first part 11 of the body 3 can be assisted by resilient means, which are not shown in the figures but are associated with the first hollow 8 of the first part 11 of the body 3 and may cooperate axially with the first arm 15 of the bow 13.
• the antitheft device is employed to clamp one of the wheels of a vehicle by fixing the body 3 to the fork or to another element forming the frame of the vehicle and by clamping the wheel by means of the bow 13.
• the antitheft device is associated with known electrical means employed to prevent theft of a motor vehicle by equipping the device itself with an electrical sensor able to reveal any tampering.
• this electrical sensor could consist of a microswitch actuated by the extension 4, 104 when it cooperates with the clamping means associated with the reversible closure means 5.
