Abstract A traction device for lifting and towing a trailer or the like comprises a frame, a pair of wheels mounted on the frame and a ball-shaped coupling member mounted on the frame. The ball-shaped coupling member is adapted to engage and disengage complementary socket coupling means carried by a trailer. A manually engageable handle is mounted on and extends rearwardly from the frame. The handle is adapted to move the frame about the axle of the wheels to move the coupling ball from a first lowered position in which the ball-shaped coupling means may engage a trailer coupling means and a second position disposed above the axis of rotation of the axle for guidably supporting the trailer. The ball-shaped coupling means projects outwardly from the frame and handle means in a radial direction with respect to the axle a distance sufficient to provide a substantial clearance between the frame, handle means and coupling means which is to be engaged so as to permit the ball coupling to be located in the first lowered position with the frame and handle means spaced from the coupling means of a trailer. A major portion of the manually engageable handle means has an axis which extends substantially less than 90* relative to the axis passing through the axle and through the centre of the ball coupling whereby the handle may be located in a lowered locked position with the ball coupling located at the opposite side of the axle.

A knock-down traction device for lifting and towing a trailer or the like comprising, a frame member in the form of a narrow strip of material formed to an arch-shaped configuration and having axially aligned passage means at opposite ends thereof, axle means releasably extending through said axially aLigned passages of said frame and projecting outwardly therefrom, wheel means releasably mounted on each outwardly projecting end of said axle means, a tubular handle member one end mounted at the apex of said arch-shaped frame member and projecting rearwardly therefrom, a ball-shaped coupling releasably mounted at the apex of said arch-shaped frame, said ball-shaped coupling releasably securing said handle means with respect to said frame, said handle means having a first portion projecting rearwardly from said frame substantially at right angles to a first plane extending through said axle and centrally of the width of said arch-shaped frame member and a second portion projecting rearwardly from said first portion at an angle less than 90* with respect to said first plane in a second plane which projects substantially radially with respect to the axis of said axle means, said handle being movable in an arc between a first position in which said ball-shaped coupling is disposed at ground level on one side of a second plane which extends vertically through the center of the axle to engage a coupling element of a trailer and a second position on the other side of said second plane wherein said second portion of said handle is disposed at ground level, said ball-shaped coupling member being adapted to support a trailer in a stable elevated station when said handle is in said second position.
