ABSTRACT:
FIELD OF THE INVENTION
This invention relates to anti-theft brake or clutch pedal locking devices for vehicles which are particularly suitable for both automatic and standard transmission vehicles. More particularly, this invention relates to devices which prevent the brake or clutch pedal from being depressed, thereby rendering a vehicle inoperable.
BACKGROUND OF THE INVENTION
Automotive theft is a major worldwide problem. The U.S. Federal Bureau of Investigation has reported that a car is stolen every 20 seconds.
The proliferation of mechanical type anti-theft devices for motor vehicles have resulted in the commercial availability of different types of anti-theft devices. One type of prior art system mechanically locks the brake and accelerator by means of two independent or articulated shoes which lock the pedals. The major problem stemming from the use of such devices is that the driver has to reach out for the pedal area or actually get down on his or her knees in order to operate the locking device, and the varying distance between the brake and accelerator which can prevent the device from being installed.
More recently, some devices have been suggested which are constructed from a long rod consisting of an anti-picking 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 locked using a safety lock that prevents the same from being disengaged. This device, which owing to its characteristics, can be employed on traditional transmission cars as well as on automatic transmission vehicles, is affected in the main by two drawbacks.
First, the connection, due it longitudinal size and cumbersomeness is difficult to store when the device is not being utilized. Secondly, devices of this nature actually have a poor record against theft. Indeed, it is relatively easy to cut the rim of the steering wheel by means of a saw or the like. The rim of the steering wheel is usually not a viable obstacle for thieves, and the anti-theft device by can be disengaged merely pulling apart the two ends of the rim. Such devices are also not usually adaptable for automatic transmission vehicles because of their structural characteristics.
In UK patent application No. 2,091,656, an anti-theft pedal-locking device for vehicles is described comprising a first supporting member extending upwards and provided with a safety lock and with a laterally projecting member and a second supporting member, upon which the first supporting member slides. A projecting member cooperates with the corresponding member of the first supporting member so as to lock a pedal of the vehicle when the latter member is in its lower position, while the lower end of the second supporting member may carry a base member to rest on the floor of the vehicle.
A number of United States Patents have also issued on brake locking mechanisms. U.S. Pat. No. 4,040,675 discloses a vehicle anti-theft device which maintains the braking function of the braking fluid by preventing reverse flow thereof from the wheel cylinder back to the master cylinder until an authorized procedure permits said backflow.
U.S. Pat. No. 4,493,198 discloses an anti-theft lock for a pedal operated apparatus. The invention incorporates first and second stop bodies which are arranged to clamp around the lever of a pedal. When the stop bodies are locked in place, the pedal cannot be operated unless the apparatus is restrained.
U.S. Pat. No. 4,934,492 discloses an automatic brake-locking mechanism which locks the brake of a vehicle having a hydraulic brake system. The system incorporates a safety switch provided to operate in conjunction with the ignition switch so that the safety switch and the ignition both must be operated to an “on” position to release the auxiliary brake device to allow normal operation of the vehicle.
U.S. Pat. No. 5,040,387 similarly discloses a vehicle brake lock assembly which engages a brake pedal and which includes a U-shaped end portion which engages the brake pedal telescopically to lock the brake pedal in position.
U.S. Pat. No. 5,345,796 discloses a vehicle brake-pedal locking device which mechanically maintains the vehicle brake pedal in a depressed position to prevent the vehicle from being driven. The device includes a horizontally and vertically pivoting brake-pedal swing arm interfacing structure.
Finally, U.S. Pat. No. 5,653,133 discloses an anti-theft device for vehicles having a steering wheel and a brake. The device comprises a brake guard moveably mounted to a fixed portion of the brake, a lower elongated member which hooks to the brake guard, an upper elongated member which is locked to the lower elongated member, a wide bar spaced a distance adaptable to be placed around the steering wheel and a locking bar and a claw member. When the device is secured with two padlocks, movement of the steering wheel and the brake pedal is prevented.
All of the above devices are so called active devices which must be actively placed on a vehicle. Passive alarms have also recently gained popularity, but these devices are expensive and frequently activate when a vehicle is accidentally struck. In addition to above discussed devices and technologies, the prior art also includes complex tracking devices which send out signals to police if a vehicle is reported stolen. The search may take up to 24 hours or longer with no guarantee of recovery. Installation of these systems is expensive and require a monthly monitoring fee. Automotive alarms are similarly expensive and may be deactivated by car thieves.
While the prior art is replete with mechanisms and inventions for locking the brake pedals of a vehicle, there is no simple and easy system devised for swiftly securing the brake or clutch pedal in a non-depressible state without the driver or operator having to get down on his or her knees or crouch down. Such a system would be to disable a vehicle, because many automobiles built since 1990 cannot start or cannot be placed into gear without the brake or clutch pedal being depressed.
The present invention is thus directed to a brake pedal or clutch pedal locking mechanism which does not require the driver or vehicle operator to get down on his knees or to move beneath the vehicle and which prevents the brake pedal or clutch pedal from being depressed. These and other objects of the present invention will be described with reference to the following summary and detailed description.
SUMMARY OF THE INVENTION
In one aspect, the invention is a device to lock a brake or clutch pedal of a vehicle so as to deter theft of the vehicle. The device comprises: a base for placement on the floor of the vehicle beneath the pedal of the vehicle and a pedal shaft supporting the pedal; a generally U-shaped housing having a second leg attached to the base member, a first leg shorter than the second leg, and a cross member connecting the first and second legs to define an opening between the first leg and the base and a slot between the first and second legs, the opening and slot being sufficiently large to receive the pedal shaft and permit travel of the pedal shaft through the slot; a locking pin selectively movable on the U-shaped housing between a raised position sufficiently close to a lower side of the pedal shaft to prevent the pedal shaft from being depressed sufficiently to enable the vehicle to be started and a retracted position to permit travel of the pedal shaft through the slot and opening; and a lock coupled to the U-shaped housing and operably connected to the locking pin to fix the locking pin in at least the raised position, the lock having an upper face with a key opening, the upper face facing substantially oppositely away from the base.
In another aspect the invention is a device to lock a brake or clutch pedal of a vehicle so as to deter theft of the vehicle, the device comprising: a base for placement on the floor of the vehicle beneath the pedal of the vehicle and a pedal shaft supporting the pedal; a general
