Mercury inertial transducer and light-emitting indicator for motor vehicles
First Claim
1. A mercury inertial transducer comprising:
- a casing which defines a substantially L-shaped cavity with a substantially horizontal lower arm and a substantially vertical ascending arm, with reference to its position of use;
a volume of mercury which, in a rest condition, occupies the lower arm and essentially does not occupy the ascending arm;
an input electrode which penetrates the lower arm from the outside and is permanently immersed in the mercury, andoutput electrode means which penetrate the ascending arm from the outside and can be reached by the mercury when the mercury rises in the ascending arm due to an inertial force directed along the lower arm and towards the ascending arm,wherein the output electrode means are constituted by a series of separate output electrodes which are spaced along the ascending arm and can be reached in succession by the mercury andwherein said transducer includes a support which can be fixed to a movable object, such as a motor vehicle, and on which the transducer is mounted so as to enable the adjustment of the inclination of its lower arm to the horizontal and of its ascending arm to the vertical.

Abstract
A mercury inertial transducer includes a casing which defines an essentially L-shaped cavity having a substantially horizontal lower arm and a substantially vertical ascending arm; a volume of mercury which, in the rest condition, occupies the lower arm and essentially does not occupy the ascending arm; an input electrode which penetrates the lower arm from the outside and is permanently immersed in the mercury, and a series of separate output electrodes which are spaced along the ascending arm and can be reached in succession by the mercury when it rises in the ascending arm due to an inertial force directed along the lower arm towards the ascending arm. The transducer may be incorporated in a unit including a support which can be fixed to a movable object, such as a motor vehicle, and on which the transducer is mounted so that the inclination of its lower arm to the horizontal and of its ascending arm to the vertical can be adjusted. The transducer may also be incorporated in a deceleration and stopping indicator including an elongate hollow body provided with means for fixing to the bodywork of a motor vehicle and carrying an array of electrical light units spaced along its length. These light units are aligned transverse the vehicle and face rearwardly with respect to the direction of travel. The inertial transducer is mounted in the hollow body and its output electrodes are each connected to at least one of the light units.

11. A light-emitting deceleration and stopping indicator for motor vehicles, comprising an elongate hollow body provided with means for fixing to a relatively high rear part of the bodywork of the vehicle, the hollow body carrying an array of electric light units which are spaced along its length, are aligned transversely of the vehicle and face rearwardly with respect to its direction of travel when the indicator is installed, and are intended to be connected electrically to the electrical system of the vehicle through the switch of the normal brake lights associated with the brake pedal, as well as through electrical distribution means which are sensitive to the degree of braking and cause lighting of an increasing number of light units as the degree of braking increases, a mercury inertial transducer comprising:
-
a casing which defines a substantially L-shaped cavity with a substantially horizontal lower arm and a substantially vertical ascending arm, with reference to its position of use; a volume of mercury which, in A rest condition, occupies the lower arm and essentially does not occupy the ascending arm; an input electrode which penetrates the lower arm from the outside and is permanently immersed in the mercury, and output electrode means which penetrate the ascending arm from the outside and can be reached by the mercury when the mercury rises in the ascending arm due to an inertial force directed along the lower arm and towards the ascending arm, wherein the output electrode means are constituted by a series of separate output electrodes which are spaced along the ascending arm and can be reached in succession by the mercury, wherein said inertial transducer is mounted in the hollow body and is arranged, when the indicator is installed, with its lower arm substantially horizontal and its ascending arm in front with respect to the direction of travel, and wherein the output electrodes of the transducer are each connected to at least one of the light units and wherein the transcducer is supported in the hollow body by fixing means which enable the inclination of the lower arm of the transducer to the horizontal and the inclination of its ascending arm to the vertical to be adjusted. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
