Abstract
A portable tire changing stand that includes a frame, a rear support leg and a horizontal front leg that attaches to the lower end of the frame and is removable. A removable center shaft perpendicular to the frame is attached to the central part of the frame. For accurate centering of the rim, a stepped bushing is arranged on the center shaft. Plastic support surfaces are attached to the frame above and below the center shaft. A tire lever is attached to the socket and a tire bead is pushed off the rim with the plate attached to the lever. The position of the plate can be adjusted by changing the distance between the bracket and the center shaft. A socket is attached to the ratchet mechanism and the lever attached to it gives the mounting head movement around the center shaft.
Claims7
A portable tire changing stand comprising:
- a frame;
- a rear support leg;
- a horizontal front leg removably attached to a lower end of the frame, the frame being located at an angle of 30-90 degrees to a bottom surface of the tire changing stand configured to rest on a supporting surface during use;
- a center shaft arranged substantially perpendicular to the frame and being removably attached to a center of the frame;
- plastic support surfaces provided for a rim of a tire, the plastic support surfaces being attached to the frame above and below the center shaft;
- a bracket attached to the upper end of the frame;
- a first socket attached to the bracket;
- a rod removably attached to the frame near a lower plastic support surface to prevent rotation of the rim, the rear support leg being rotatably connected to the frame;
- a ratchet mechanism attached to the center shaft;
- a tire mounting head;
- and a second socket attached to the ratchet mechanism;
- a lever adapted to be removably inserted into the first socket and the second socket alternatively;
- and a plate attached to the lever, the plate adapted to be put into contact with a side surface of the tire, wherein after inserting the lever in the second socket, applying a downward pressure on the lever will provide movement to the tire mounting head around the center shaft, and the ratchet mechanism enables the lever to be freely returned to an initial position relative to the tire mounting head, whereby the movement is repeatable.
