Description
REF 2425/92 ANTITHEFT GEAR LEVER LOCK FOR CARS ANTITHEFT GEAR LEVER LOCK FOR CARS The present invention relates to an antitheft gear lever lock for cars in the form of a bracket locking the gear lever to the floor of the car.
Antitheft devices for cars locking mechanically the gear lever are known. They essentially consist of a padlock closure mechanism with a body which is irgidly connected to one end of a bracket, the other end of which is bolted to the floor of the car, and with a bend supported by such body which can be snap-locked to and unlocked from the latter and in the operating position is caused to embrace the gear lever in order to lock it in the reverse gear position in case of cars with manually operated gear shift and in the park position in case of cars with automatic gearshift.
However, such antitheft devices have some drawbacks. One drawback relates to the locking bracket of the padlock closure mechanism. Such drawback consists in that the brackets used hitherto are not made of a material which is plastic enough to be easily bent by a fitter so that there is no chance to adapt the brackets to any car model and then a particular bracket must be used every time. A second drawback relates to the body including the padlock closure mechanism which is supported by the bracket when the gear lever lock has to be brought to the rest position. Presently, the body is provided at the upper side with a groove and two tabs standing from said body and parallel to and urged away from each other by a spring. A bend is slidingly inserted into such groove so as to engage said tabs in order to overcome the force of the spring and to reach its rest position. The described operation is very hard to be carried out by the driver.
As far as the first drawback is concerned it was surprisingly found that the manganese steel under solubilized state having a Brinell hardness of 2 approximately 220 kg/mm has in combination hardness and plasticity such as to provide a bracket which is hard enough to withstand to cutting nippers, saw, picklock or the like burglary tool, and at the same time plastic enough to be easily bent and adapted to any car.
In order to overcome the second drawback, the padlock closure mechanism is provided at the upper side with a mount having two openings adapted to receive the two parallel ends of the locking bend introduced by the driver from above with a suitable angle of inclination. The openings are adjacent to the spring-loaded tabs, the plane of such openings being parallel to the axis of the spring loading the tabs. The bend is introduced in a slanting attitude until its parallel arms abut the spring-loaded tabs from above. The rest position of the bend is then reached by an easy rotation of the same about an axis parallel to that of the spring, thus urging the tabs against the action of such spring, the edge of said openings acting as a bearing in such rotation.
Therefore, an object of the present invention is an anti theft gear lever lock for cars which is characterized in combination by: a bracket forged by manganese steel under solubilized state and having a Brinell hardness of 2 approximately 220 kg/mm , said bracket being sized and formed as well as provided with a set of holes in one end part . such as to allow it to be applied to any car by a fitter through an appropriate, easy bending of the bracket which is then bolted to the floor of the car through the most suitable holes; a padlock closure mechanism supported by said bracket and adapted to lock the gear lever by a bend embracing and retaining said lever in the operative position and being able to reach its rest position by an easy rotation movement. The bracket is further characterized in that its part not provided with the set of holes, i.e. that part standing up from the floor, is subjected to a hardening by surface nitrocarburizing .
The present invention will be better understood with reference to the accompanying drawings which show by way of a non-limitative example a preferred embodiment thereof. In the drawings: Figs. 1a and 1b show a front and a side views of the bracket .
Fig. 2 is a perspective view of the gear lever lock of this invention under operative conditions; Figs 3a and 3b are two perspective views of the same gear lever lock under rest conditions with the locking bend in a first inclinated position and in the final position.
Fig. 4a and 4b show two embodiments of the gear lever lock mechanism; and Fig. 5 shows the bend of the gear lever lock.
As shown in Figs. 1a and 1b bracket 1 has an end section 2 provided with fixing holes 3 for its bolting to the floor of the car, a head member 4 provided with holes 5 for the connection to the antitheft padlock closure mechanism, and an intermediate member 6, at the end of which the bracket can be bent to be fitted to the car. Both head and intermediate members are subjected to hardening by nitrocarburizing .
As shown in Figs. 1b, 4a and 4b, bracket 1, which has been bent at 8' , 8" before the nitrocarburizing in order to be adapted to the gear lever, is bent at 8 when being assembled, i.e. before the connection to the floor 10 of the car by means of anti-burglary bolts 12 screwed through holes 3 so that head 4 of the bracket is brought near gear lever 14 to support the padlock mechanism 16. The padlock mechanism 16 comprises an essentially rectangular box-like body 18 housing in a cavity the padlock (not shown) aligned with the through-holes 24. The diameter of said through-holes corresponds to that of the ends 25 of the arms 26 of the bend 28 locking the gear lever in the operative position, as shown in Figs. 2, 4a and 4b. The bend 28 has two parallel arms 26 with ends 25 having less diameter and provided with notches 27 to be engaged by the padlock.
In order to arrange the bend in its rest position, the box-like body is provided at its upper side with a mount 30 having two openings- 32 adapted to receive from the above the ends 25 of the arms 26 with an angle of inclination. Two tabs 34 standing from the upper side of said body are arranged parallel to and urged away from each other by a spring having an axis lying parallel to the plane of the two openings 32. The openings 32 have such a diameter as to be able to receive only the ends 25 of the arms 26. In this position the arms 26 abut against the openings 32 and the tabs 34 (fig. 3a). Once inserted the ends 25 into the openings 32 the driver rotates the bend 28 downward against the spring-loaded tabs 34 until the horizontal rest position of the bend is reached (Fig. 3b).
The present invention has been described and illustrated with reference to a preferred embodiment thereof, however, it is obvious that changes and/or modifications can be made by those skilled in the art without departing from the scope of the appended claims.
