## Title
Anti-theft pedal locking device for motor vehicles

## Abstract

A portable anti-theft brake pedal locking device for a motor vehicle, comprising a horizontal barrier member, upwardly extending, u-shaped rod shackle engaging members, and a manner of locking the device against removal from beneath existing brake/clutch pedal(s). The manner of locking may be either by a lock integral to the anti-theft device, in the form of a pivoting catching lock member, or by a lock independent of the anti-theft device, such as by a padlock. This portable anti-theft device in its preferred embodiment may be double-locked through use of the lock integral to the anti-theft device, and also secondarily by use of the independent locking padlock. Through the placement of this device beneath the under edge of a brake pedal shaft, the under edge of a clutch pedal shaft when present, against the vehicle floorboard, and locking the device to the brake pedal shaft, a resulting disabling of the operation of such pedals is accomplished by preventing the pedals being depressed. This anti-theft device is a significant improvement over prior art in being universal as to application, simple in its operation, compact and thus easily stored.

BACKGROUND OF INVENTION
1. Field of Invention
This invention relates to a portable, anti-theft brake pedal locking device for motor vehicles, a device that encompasses an additional barrier to clutch operation when a clutch is present, this device being suitable for manual as well as automatic transmission systems. Specifically, the invention incorporates a system that prevents the brake/clutch pedal(s) from being depressed.
2. Prior Art
Patents have been issued on anti-theft devices since the inception of the motor vehicle for transportation. Some of these inventions have been less than credible. More usually, the inventions have been impractical, could be defeated without great effort, and in some cases hazardous when put into use. In all cases portable anti-theft devices should be: maximally secure; user friendly; light in weight; easily stored; universal as to employment; designed to be efficiently manufactured; reasonable in cost; and visible. Prior art anti-theft inventive solutions have failed in one or more parts to equal the foregoing condition.
Inventions incorporating steering wheel and steering wheel to brake/clutch pedal(s) locking have been patented. Such devices are not secure due to the fact that they are easily defeated by the simple act of cutting the wheel rim. (By reason of safety, a steering wheel rim should not be fabricated of hardened metal, in that malleability of its fabrication offers some protection to the driver in case of impact.) Usually, these devices are also complicated to install and difficult to be stored.
U.S. Pat. No. 4,856,308, Aug. 15, 1989, Johnson, discloses an elongated body member incorporating hooking means, lockable to a steering wheel, preventing its easily being turned.
U.S. Pat. No. 5,704,233, Jan. 6, 1998, Farshad, discloses a rod member, extending from a brake pedal catch member to a steering wheel catch member, lockable and thereby preventing operation of either steering wheel or brake pedal.
U.S. Pat. No. 6,653,133, Aug. 5, 1997, Passantino, discloses a connection between a steering wheel and brake pedal of a most complex character.
Other anti-theft devices are either wholly or in part permanently installed on the vehicle. Damage to the vehicle can be incurred through such installations; these installations are always expensive; hazards to the occupants are at times introduced; inconvenience in almost every case is increased; and the disabling of such devices is sometimes accomplished by the removal of a single connector. These devices are also not compatible to many vehicles.
U.S. Pat. No. 5,263,345, Nov. 23, 1993, Zagorac, discloses a cable extending between a lockable safety-brake lever, connected to a floor member beneath the operator pedals, activated by the engagement of the safety-brake lever.
U.S. Pat. No. 5,040,387, Aug. 20, 1991, Knott, Jr., discloses an assembly between a lockable means and an engaging cable, extending to an apparatus that extends upwardly through the floorboard under a brake pedal, designed to clasp the pedal in a depressed position when the system is activated.
U.S. Pat. No. 4,934,492, Jun. 19, 1990, Hayes-Sheen, discloses a hydraulic brake locking system, activated by turning off the ignition switch, and maintaining the brake in a locked position until the system is deactivated.
Electronic anti-theft systems suffer from being expensive installations; from being readily defeated by any knowledgeable person; by being an insecure means of protection when a vehicle is parked or stored at some remote location. Backpackers, hunters, fishermen, bird watchers and skiers, who will often park a vehicle at the end of some roadway, gain little protection from such electronic means. By the time such persons return to their vehicles ample time has expired to fully disable even electronic locator systems.
BRIEF SUMMARY OF THE INVENTION
In summation, any vehicle anti-theft device functions in only a deterrence capacity. Every device may eventually be defeated. Of the eight categorized features listed above, it is believed the vehicle anti-theft device herein being submitted for patenting is more fully in compliance then other prior art. It should be readily recognized that the present design is compact enough to to be easily stored within the passenger compartment of any vehicle. Its simplicity of design permits use of this anti-theft device in most vehicles. The double-locking features of the preferred embodiment of this device offers considerable deterrence against theft. In all cases, the clustering of locking members about the brake pedal shaft renders difficult access for purposes of cutting or prying against said shaft. Manufacture of the present design presents no difficulty to those persons versed in the art of mass production. Visibility may be easily assured, by the location of decals or other identifiers about noticeable locations of the vehicle.
It is accordingly an outstanding objective of the invention to provide an improved design for a vehicle anti-theft device, one that may be easily placed beneath the brake/clutch pedal(s) of a vehicle, locked in place, thereby disabling the operation of such pedal(s), and thus preventing the theft of the motor vehicle.
Another objective is to provide a vehicle anti-theft device that may be easily stored within the passenger compartment of a motor vehicle. In the instance of this present invention, a device compact enough to be stored under a seat, or in a dashboard compartment of the vehicle, the stated requirement is satisfied.
Still the further objective is the provision of a vehicle-anti-theft device of the foregoing character, that may be easily manufactured, and thus economical in cost to the end-user.
