Description: AN ANTITHEFT PEDAL-LOCKING DEVICE FOR VEHICLES This invention relates to an antitheft pedal-locking device for vehicles, which is particularly suitable for automatic transmission vehicles. More particularly, this invention relates to a de¬ vice of the type mentioned above which allows the oper¬ ation of at least one pedal to be safely locked, The study and the realization carried out in the recent years of mechanical type antitheft devices for motor vehicles have resulted in the commercial avail¬ ability of different types of antitheft devices, which are affected however by a number of drawbacks of a general type or more specifically as regards their employment in automatic transmission motor vehicles. More particularly, reference is made herein to a first kind of realization, which provides the mechanical locking of pedals, particularly the brake and the clutch pedals, said realization consisting of two independent or articulated shoes, which lock said pedals by means of a safety lock that is usually arranged near said shoes. The major problem stemming from such kind of device is that connected with the fact that the driver has to reach out quite uncomfortably his hands for the pedal area in order to operate the locking device. More recently, some devices have been suggested which are made of a long rod consisting of an anti-pick¬ ing material and which is provided at both ends with two shaped members that couple respectively with a pedal and with the steering wheel of the vehicle. The coupling with the steering wheel is obviously locked by means of a safety lock that prevents the same from being disengaged. This device, which owing to its characteristics can be indifferently employed on traditional transmission cars as well as on automatic transmission vehicles is affected in the main by two drawbacks. The first one is that in connection with its longi- tudinal size, and as a consequence with the cumberso e- ness of such device when it is not employed, while the second drawback, which is perhaps the most relevant, is that in connection with the poor safety against theft. Indeed, it is sufficient to cut the rim of the wheel by means of a saw or the like, as said rim is usually not a valid obstacle for thieves, and then to disengage the antitheft device by merely pulling apart the two ends of the rim so cut. The Applicant himself has invented and realized an antitheft device which is the object of the Italian patent No. 1,149,007, which obviates all drawbacks mentioned above as it is so realized as to allow the pedals to be locked by the driver in the driving position and without interacting with the steering wheel. However, such device is not fit for automatic trans¬ mission cars because of its structural characteristics, and it provides anyway the locking of two pedals which are not spaced too much from one another. Indeed, it is well known that cars with automatic transmission lack the clutch pedal, and in addition the brake and the gas pedals are spaced from one another much more than said pedals are in the case of tra¬ ditional vehicles. In the light of what has been mentioned above, the Applicant has intended to realize an extremely simple antitheft device which can be employed indifferently both on traditional and on automatic transmission cars, said device providing the locking of at least one pedal (the brake pedal in the case of automatic transmission cars, and the clutch pedal in the case of traditional transmission cars) and, possibly, the impediment of the motion of a second pedal (the gas pedal in the case of automatic transmission cars, and the brake pedal in the case of traditional transmission cars). Accordingly, it is a specific object of the present invention an antitheft pedal-locking device for motor vehicles, said device comprising a first support that extends upwards, and is provided with a safety-lock and, at the point corresponding to its lower end, with a shaped member projecting laterally so as to create a seat for locking a pedal of the motor vehicle; a second support on which said first support slides between a locking position and an unlocking position, said support being provided with a projecting member of such shape and sizes as to realize, together with said shaped member, when the first support is in the locking position, the lower locking of the locking seat of the pedal; and a base member to which the lower end of the second support is coupled for realizing the support of the device on the floor of the vehicle. Said second support can be so realized as to have at the point corresponding to the projecting member, at a position below the locking position of the first support, i.e. at the lowest position that it can reach in its sliding along the second support, a change in its angular position. The coupling between the base member and said second support can be realized through a sleeve, which is arranged on said base member, the lower end of said second support sliding inside said sleeve, said sliding being realized through mechanical means, as for instance through a screw-nut screw coupling, which is obtained inside said second support, so that the possibility is realized of adjusting by acting from the outside part by means of a socket head screw, or by a screw driver or the like, the height os said projecting member, and hence of the whole locking device, with respect. to the floor of the vehicle. Two projecting parts which are arranged laterally on the respective angles are provided inside the locking seat, on the inner upper wall created by the shaped member of the first support, and on the inner lower wall created by the projecting member of the second support. Again according to the present invention, a third support can be provided on said base member, said support being laterally spaced and in the parallel position, and bearing a member capable of obstructing the motion of a second pedal. The coupling between said third support and said ob¬ struction member can be of the fixed or of the oscillat- ing type so that there is the possibility of rising the - obstruction member when the device is not employed, so as to limit the space occupied by the device itself. In that case also, the coupling between the base and said third support can be realized by means of a further sleeve which is fastened to said base, inside which sleeve said third support is caused to slide through mechanical means, such as for instance those disclosed above, so that the height of said obstructing member can be adjusted at will. The obstructing member can be made up of a single member that is arranged on the back of the pedal, or such member can be made up of two substantially parallel members that are arranged respectively in front of the pedal and on the back of the same. The shaped member of said first support can be bev¬ elled at the points corresponding to a top edge of said seat in correspondence to the locking seat of the pedal, In order to adapt said seat to any kind of pedal. This invention will be disclosed in the following according to its preferred embodiments with particular reference to the figures of the enclosed drawings, wherein : Figure 1 is a perspective view of a first kind of embodiment of the device according to the present inven¬ tion; 5 Figure 2 is a vertical cross-sectional view of a detail of the device shown in Figure 1; Figure 3 is a perspective view of a second kind of embodiment of the device according to the present inven¬ tion; and 10 Figure 4 is a front view of a third kind of embodi¬ ment of the device according to the present invention. The device illustrated in Figure 1 and in Figure 2 comprises a supporting member 1 whose upper end is pro¬ vided with a safety lock 2 and whose lower end is pro- 15 vided with a shaped member 3 for locking the pedal 4. Said supporting member 1 is slidably assembled on a second supporting member 5 which is provided with a projecting side member 6. The position of said side projecting member 6 on 20 said supporting member 5 is such that it coincides with the open position of the shaped member 3 when the supporting member 1 is in its lowest sliding position along the supporting member 5, so that a complete lock¬ ing of said pedal 4 is obtained. 25 The supporting member 5 is coupled at the end which is opposite to the coupling end with the supporting mem¬ ber 1, to the sleeve 7 of a supporting base 8 of the device on the floor of the vehicle. Obviously the shape of said supporting base can be modified according to the J specific requirements. The coupling between the supporting member 5 and the sleeve 7 of the base member 8 is obtained through the interposition of a coupling by means of the screw 9 and the coupled nut screw 10 so that the distance of the O member 6 from the floor of the vehicle can be adjusted by means of a socket head screw or the like, according to the kind of the motor car and to the position of the pedal. The slope of the supporting member 5 is changed (see Figure 2) at the point corresponding to the member 6, such change in the slope allowing the device according to present invention to be positioned in a better way. The two strikers 18 and 19 which are provided respectively on the shaped member 3 and on the project¬ ing member 6 allow the device according to the present invention to be adapted to any kind of pedal 15. As illustrated in the following, the supporting mem¬ ber 5 can also be realized without any change in its slope. A device like that disclosed and illustrated in Fig- ures 1 and 2 can be indifferently employed both on motor vehicles with the traditional speed gear or transmissio " by locking the clutch pedal, and on automatic trans¬ mission vehicles, by locking the brake pedal. For employing the device of this invention, it is sufficient to arrange the supporting member 1 in the un¬ locking position, i.e. in the position of maximum slid¬ ing extent upwards with respect to the supporting member 5 (the position of the member 3 which is shown in dashed lines in Figure 1), then to arrange the device in the position with the member 6 below the bar of the pedal 4 and then to cause the supporting member 1 to slide by pushing it along the supporting member 5 till the mem¬ bers 3 and 6 cause the locking of said pedal 4 to be realized. The shaped member 3 can be provided with a bevelled part at the point corresponding to an upper edge, in the inner part of the housing that is formed by said member, so that also pedals whose bars do not adapt perfectly to the housing so formed can be locked. For the unlocking operation, it is sufficient to act on the key of the safety lock 2 and then to pull the supporting member 1 upwards. The device illustrated in Figure 3, whose members that correspond to those of the device shown in Figure 1 are pointed out by the same reference numerals, has a straight line support 5. A second sleeve 11 is provided on the base member 8, in which sleeve a supporting member 12 is slidably arranged. A member 14 for obstructing said pedal 15 is coupled to said supporting member 12 so that the obstruction member can oscillate about the pivot 13. The member 14 can be folded upwards when the device is not in use, so that the space occupied by the device itself can be reduced. The position of the member 14 can also be adjusted by causing the supporting member 12 to slide along the sleeve 11 by means of a mechanical device (not shown) which is similar to that disclosed above. In order to use this device, it is sufficient to in¬ sert laterally the device itself, after taking the supporting member 1 into the unlocking position, so that the member 14 is taken below the pedal 15, while the member 6 is taken below the pedal 4, and then to cause the supporting member 1 to slide along the supporting member 5 till locking is obtained. This kind of device, just like that shown in Figure 4, can be advantageously employed on motor cars having automatic transmission to lock the brake pedal (pedal 4) and obstruct the gas pedal (pedal 15), or on traditional transmission vehicles to lock the clutch pedal (pedal 4) and to obstruct the brake pedal (pedal 15). The member 14 can also be so shaped as to act as an obstruction to the motion of the pedal 15 both in front of it and on the back of the same. The device shown in Figure 4 has the same features as that shown in Figure 3, except as regards the coupling between the member 14 and the supporting member - a - 12 which in that case is of the rigid type. Figure 4 shows the screw 16-nut screw 17 coupling for adjusting the position of the member 14. This invention has been disclosed with specific ref¬ erence to some preferred embodiments of the same, but it is to be understood that modifications and/or changes can be introduced by those who are skilled in the art without departing from the spirit and scope of the in¬ vention for which a priority right is claimed.
