Patent ID: 7600621

Claim:
A reinforced safety device for collecting electrical energy at ground level for a land-borne ground level electrical feed vehicle by a sliding contact with at least one polar part, the safety device comprising: a collection blade ( 10 ) having a vehicle support holder ( 11 ) on an upper part of the collection blade ( 10 ); the blade ( 10 ) being configured to be raised by a raising device and to be connected to a feed circuit of the vehicle, the blade ( 10 ) being electrically insulated from ground and any lane structures, a part of the blade ( 10 ) being configured to spread apart two profile holding fixtures ( 23 , 24 ), which are placed side-by-side facing each other opposite to one another, the two profile holding fixtures ( 23 , 24 ) run either on the ground or in the ground along a lane, and are supported by a profile carrier support ( 21 ) having a bottom that is approximately flat and two lateral walls to form a collection assembly ( 9 ), the blade ( 10 ) has at least one surface ( 17 , 18 ) that is maintained in direct sliding electrical contact along one of conductors or conducting parts ( 19 , 20 ) which are supported by said profile holding fixtures ( 23 , 24 ), each of the profile holding fixtures ( 23 , 24 ) is provided with at least one elastic restoring return ( 25 ) to urge a respective one of the profile holding fixtures ( 23 , 24 ) towards the other one of the profile holding fixtures ( 23 , 24 ) by elastic compression engendering locally an elastic restoring force to urge the profile holding fixtures ( 23 , 24 ) together after lateral compression.
