Abstract
A trailer including: i) a draw bar; ii) a trailer frame supporting a trailer bed; iii) an arm including a first pivot mount; iv) an axle pivotally connected to the arm at the first pivot mount; v) an actuating mechanism actuatable to exert a force on the arm relative to the trailer frame. The axle includes at least one associated wheel and the wheel has a plane of rotation in which the wheel rotates when traveling in a forward direction, and the actuating mechanism is located substantially in the plane of rotation. The trailer bed may be raised or lowered by exerting a force on the arm relative to the trailer frame.
Claims47
A trailer comprising:
- i) a draw bar;
- ii) a trailer frame supporting a trailer bed;
- iii) an arm including a first pivot mount;
- iv) an axle pivotally connected to the arm at the first pivot mount;
- v) an actuator actuatable to exert a force on the arm relative to the trailer frame;
- wherein the axle includes at least one associated wheel and the wheel has a plane of rotation in which the wheel rotates when traveling in a forward direction, and the actuator is located substantially in the plane of rotation;
- whereby the trailer bed may be raised or lowered by exerting a force on the arm relative to the trailer frame;
- wherein the trailer frame includes a second pivot mount, the arm being pivotally movable relative to the trailer frame about the second pivot mount;
- and
- wherein the trailer frame includes a third pivot mount located higher than and rearward of the second pivot mount, the actuator pivotally mounted to the third pivot mount and actuatable to exert a force on the arm resulting in rotation of the arm about the second pivot mount.
A trailer comprising:
- a draw bar;
- a trailer frame;
- a wheel carrying structure pivotally connected to the trailer frame and carrying at least one wheel;
- and
- an actuator actuatable to exert an at least approximately vertical force on the wheel carrying structure, at a location fore or aft of the pivotal connection between the wheel carrying structure and the trailer frame, to move the trailer frame between a lowered position, in which the trailer frame is in proximity to the ground to be loaded therefrom, and a raised position for towing;
- wherein the wheel has a plane of rotation in which the wheel rotates when traveling in a forward direction, and the actuator is located substantially in the plane of rotation.
A trailer comprising:
- a draw bar;
- a trailer frame;
- a wheel carrying structure carrying at least one wheel;
- and
- an airbag pivotally mounted to the trailer frame actuatable to exert a force on the wheel carrying structure to raise or lower the trailer frame.
A trailer comprising:
- a draw bar;
- a trailer frame;
- and
- at each side of the trailer
- a wheel carrying structure carrying at least one wheel;
- and
- a pneumatic actuator to exert a force on the wheel carrying structure to raise or lower the trailer frame;
- wherein each pneumatic actuator is isolated for stability of the trailer while towing.
