Abstract
Description
Title of the invention: Multi-use electric urban transport vehicle and stair lift.
[0001] The present invention relates to an urban transport vehicle with a front axle of three wheels on each side fixed to a triangle connected to a shaft driven by an electric motor ensuring rotation allowing climbing stairs and a rear axle of a central wheel equipped with an electric motor ensuring mobility.
[0002] This vehicle equipped with a frame fixed vertically to the platform carrying a shopping bag and a battery will allow you to move around in an urban environment and by folding the driving part will allow you to move around in shopping centers and shops and climb stairs.
[0003] The vehicle according to the invention is constituted, as shown in [Fig.l], and in [Fig.2], of a platform (6) fixed at the front to a tube (14) through which passes a shaft passing through an electric motor (4) secured to two triangles (9) on each of which are fixed three wheels (1). Two wheels on each side are held in the high position by a plate (13) sliding in a rail (12) actuated by a handle (11) and inserted between the upper wheels. This plate is raised to climb the stairs. A frame of metal tubes (15) welded vertically to the platform (6) supports a metal box (3), two batteries (2) and two handles (16). At the rear of the platform (6) is fixed a fork (10) equipped with a wheel (5) provided with an electric motor and a disc brake. A set of two casters (8) can be unfolded to provide stability when the drive part is raised at the hinge (17).A disc (7) fixed on a tube sliding in a rail moved by a handle (18) which allows the front wheels to be braked by pressure on the tire.
