An exemplary power driven vehicle has a take-apart frame comprising a front frame and a rear frame that are detachably and pivotally connected together. The front frame includes means for receiving at least one steerable wheel and a steering mechanism and means for receiving a seat, and the rear frame includes means for receiving at least two drive wheels. The vehicle also has at least one steerable wheel, a steering mechanism, and a seat connected to said front frame. At least two drive wheels are pivotally connected to said rear frame via a single axle. An electric motor is mounted on the rear frame and adapted to drive at least one of the drive wheels. A shroud partially covers the front frame and is fixedly connected thereto. At least one battery box is detachably mounted on the shroud and is in electrical communication with the electric motor. A locking and unlocking means of the vehicle is adapted to prevent, or alternatively allow, the disconnection of the rear frame from the front frame. The locking and unlocking means comprises a locking lever pivotally connected to the front frame. At least one groove or recess in the locking means engages the rear frame when the vehicle is in its normal position, thus preventing the rear frame from pivoting relative to the front frame. In an unlocking position the rear frame is allowed to pivot relative to the front frame, thereby allowing the rear from to be disconnected from the front frame. |

1. A power driven vehicle used by at least partially disabled persons for mobility, the vehicle comprising:
a frame having a front frame and a rear frame that are detachably and pivotally connected together, said front frame comprising means for receiving at least one steerable wheel and a steering mechanism and means for receiving a seat, and said rear frame comprising means for receiving at least two drive wheels, at least one steerable wheel, a steering mechanism and a seat connected to said front frame, at least two drive wheels pivotally connected to said rear frame via a single axle, an electric motor mounted on said rear frame and adapted to drive at least one of said drive wheels, a shroud covering at least partially said front frame and fixedly connected thereto, at least one battery box detachably mounted on said shroud and in electrical communication with said electric motor, locking and unlocking means adapted to prevent, or conversely permit, the disconnection of said rear frame from said front frame, wherein said locking and unlocking means comprises a locking lever pivotally connected to said front frame moveable between a locking position, in which at least one groove or one recess provided in said lever defines an abutment against which abuts said rear frame when the vehicle is in its normal position of use, thus preventing said rear frame from pivoting relative to said front frame, and an unlocking position, in which said rear frame can pivot relative to said front frame, thus permitting the disconnection of said rear frame from said front frame, and wherein said locking lever is configured so as to move from its locking position to its unlocking position when said battery box is detached from said shroud. |
