DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD OF THE INVENTION
The object of the present invention is a locking device for the automatic transmission gearshift lever of automobile vehicles.
BACKGROUND OF THE INVENTION
Known in the art are many embodiments of locking devices which have the purpose, under certain circumstances, such as when the vehicle is parked, of acting upon the gearshift lever to render it impossible to drive the vehicle. Such locking devices are generally actuated by the user once the vehicle has been parked, and require that the user proceed deliberately to unlock them to make it possible to drive the vehicle.
The known embodiments of locking device such as those described present, totally or partially, the following disadvantages: that is, the gearshift lever can be locked in a position other than the parking position, which can mean that when the user unlocks the device, starting of the vehicle engine is implemented with the gearbox set up in driving conditions, thus causing a situation which is at the very least difficult; actuated only in those cases when the user deems it appropriate; this leads to situations where it is possible to make undue use of the vehicle in all cases in which the device is not operative; nuisance, while it also lends the vehicle a finish which, on a certain type of vehicles, is scarcely acceptable; disadvantage due to it being the usual practice to centralize vehicle systems such as door locking, steering lock, etc., in a single key, which is also the ignition key.
EXPLANATION OF THE INVENTION
An automatic transmission gear lever locking device of original structure and operation is made known hereby in order to provide a new embodiment of locking device which provides a solution to all the above-mentioned problems. The locking device of the invention presents the main advantages detailed below: starter switch on the vehicle dashboard; ignition key, thereby immobilizing the gearshift lever and avoiding manual actuation of the device; withdraw the ignition key the driver of the vehicle must move the gearshift lever to the parking position, this advantage providing a special solution to those disadvantages deriving from the operation of known embodiments of locking devices which operate independently of the position of the gearshift lever; from the exterior, which largely prevents it being manipulated in an undue or unauthorized manner, so that in a complementary manner it exercises the function of an effective anti-theft device.
The locking device of the invention comprises a reset device and a securing mechanism linked by a control cable made up of a sheathed steel cable, in which: dashboard through a contact stem with two working positions provided by coupling of the ignition key with the switch, a first position or parking position in which the ignition key is not coupled with the switch, and a second position or drive position in which the ignition key is coupled with the switch; stem and a thrust spring, in which the main body houses the contact stem and the retaining stem, both of which can slide in both directions, with the retaining stem being provided with means of coupling with the contact stem and, being linked by one of its ends to the corresponding end of the steel cable of the control cable, the thrust spring acts permanently upon the retaining stem, pushing it towards the interior of the main body and tending to situate it in its most advanced position, or locking position, all this in such a way that, with the contact stem in the parking position and the retaining stem in the locking position, both stems can be coupled to prevent sliding of the retaining stem and; lever and to the lever support and linked at the other end of the steel cable of the control cable, implementing coupling of the traction body with the support in such a way that the traction body can rotate in both directions around a pivot pin, the traction body being coupled with the lever in such a way that the position of the traction body corresponds with that of the lever, the locking position bei
