ABSTRACT:
TECHNICAL FIELD
The present invention relates to an anti-theft device for scooters, motorvehicles, snowmobiles, outboard motors, helicopters and other vehicles provided with a fuel control twist grip, which affects the fuel control twist grip, or the twist grip otherwise known as the accelerator twist grip.
BACKGROUND ART
Up to now, the fuel control twist grip of a scooter or similar vehicle has always been manufactured in a single piece, covered, on the outside, with a rubber or similar grip, for secure gripping on the part of the driver, and connected, in the part facing the handlebar, with flexible transmission means connected to the carburettor and supported in the handlebar by a tubular support element at the end of which the fuel control twist grip is usually located.
All anti-theft devices up to now designed for and applied to scooters or motorvehicles in general, have been designed to control the possibility of manoeuvring and turning the handlebar around the steering axis or on the electrical power supply to the motor. These types of anti-theft device have proved to be quite inefficient, since they can easily be overcome.
Another type of anti-theft device in use is that which uses mechanical means for blocking the wheel(s), or again the handlebar, in the form of chains or rigid shackle-type locks which are fitted with suitable safety locks. This type of anti-theft device has demonstrated greater resistance to braking or cutting, but still relies on a lock which can be broken and is awkward and inconvenient to carry around and to apply.
Still another type of anti-theft device disclosed in the French patent FR-A-1 132 662 and in the French patent application FR-A-2 598 995 comprises a lock co-axially disposed inside the fuel control twist grip and capable of blocking the rotation of the twist grip by making the twist grip coupled to the handlebar of the motorvehicle. However, also this type of anti-theft device relies on the lock which can be broken.
DISCLOSURE OF THE INVENTION
The main aim of the present invention is to manufacture an anti-theft device which involves the removal of an essential element required for starting up and running the motorvehicle, not easily replaced with other means, which is easy and quick to remove and re-fit and, therefore, to use.
The innovative idea on which the present invention is based, therefore, is to manufacture a fuel control twist grip for a scooter or similar motorvehicle in two separate parts to create an anti-theft device which affects the fuel control twist grip which involves its physical release and removal from the handlebar of the motorvehicle.
The innovative idea also includes the creation of a system for closing and therefore blocking access to the flexible transmission elements of the fuel control in the body of the handlebar.
Another aim of the present invention is to create an anti-theft mechanism, of the type indicated above, with which it is also possible to block the brake lever, for the cases in which it is present, said brake lever being functionally associated to the handlebar on the same side as the said fuel control twist grip, to provide further protection against theft.
The invention, which is characterised by the claims which follow, solves the problem of providing an anti-theft device for scooters, or other motorvehicles, which affects the fuel control twist grip, which, from a general point of view, is characterised in that the said twist grip is manufactured in two co-axial consecutive parts which can be rigidly coupled together, of which the first part is a removable tubular element (preferably covered on the outside with an integral grip) and the second part is a non-removable tubular element, present in the handlebar and held by the flexible transmission means of the fuel supply control; this involves engagement means between the said removable tubular element and the said non-removable tubular element and a closing locking block for the non-removable tubular element when the said removable tubular element is disengaged and removed.
Advantageously, the said non-removable tubular element is fitted with a through hole for a connecting arm of a mechanism that blocks the brake lever, which is found on the same side as the said twist grip, in the braking position.
From the conceptual point of view, the anti-theft device described above is manufactured by cutting the conventional fuel control twist grip in two pieces, without in any other way modifying the flexible transmission of the control itself, or any other type of acceleration control for a motorvehicle. Therefore, the anti-theft device described by this invention may be supplied in a kit for modifying scooters which have already been manufactured or can be fitted to new scooters.
