PURPOSE:To enable getting out of snow road or muddy road by fixing telescopable foot members to the left and right at the rear section of car and moving the car forward while telescoping said members alternatively. CONSTITUTION:Telescopable feet 1 are fixed to the left and right at the rear section of car. Said feet 1 are constructed of parallel links where the shorter link 41 is secured to a lateral shaft 5 to be rotated through a hydraulic cylinder 8. While a stepboard 15 is fixed through an auxiliary link 16 to the end section of link. The parallel link is made telescopable through a gear 18 by means of a motor. In order to get out of snow road, the foot section 1 at one side is extended by means of a motor to press the stepboard against the ground then the lateral shaft 5 is rotated through hydraulic cylinder 8 thus to push the car forward. Thereafter, another foot section 1 is functioned similarly to push the car further forward. Said function is performed alternatively to get out of snow road. |
