Vehicle wheel rim straightener and method of use thereof
DCFirst Claim
1. A device for straightening out a vehicle wheel rim, comprising:
- a presser;
opposing pressure members on opposite ends of said presser;
a power device for powering said presser to move said opposing pressure members outwardly away from each other;
a first semi-spherical contact member on a first of said pressure members;
a second semi-spherical contact member on a second of said pressure members;
said first and second semi-spherical contact members having outwardly facing spherical surfaces;
wherein said first and second semi-spherical contact members are fittable within a vehicle wheel rim for straightening a bent portion of the rim;
a securing device for securing said presser to a wheel rim, said securing device including a member that extends over said presser and a member that engages an opposite side of said wheel rim through a center hole in said wheel rim; and
wherein the presser is a ram and the power device is a hydraulic pump.

Abstract
A device for straightening out a vehicle wheel rim includes a ram and a hydraulic pump for manually operating the ram. Opposing pressure members are on located at opposite ends of the ram, and two semi-spherical contact members are contacted by the pressure members. In use, the semi-spherical contact members are fittable within a vehicle wheel rim for straightening a bent portion of the rim. The method is preferably performed with heating of the rim. Accordingly, the present invention provides a number of advantages which were not before possible with existing methods, including that the device can be completely portable, that the device does not require electricity nor other power source to operate, that it takes little training or expertise to operate, that it is relatively inexpensive to manufacture, and that it takes much less time than the currently used methods.

8. A method for straightening out a vehicle wheel rim, comprising the steps of:
-
a) providing a device comprising;
a presser having opposing pressure members;
a power device for moving said opposing pressure members of said presser outwardly away from each other;
a pair of first and second contact members which are removably replaceable on a first of said pressure members and a second of said pressure members, respectively;
said first and second contact members having outwardly facing contact surfaces;
wherein said step of providing further comprises the step of providing the presser as a ram and the power device as a hydraulic pump;b) placing the pressure members inside a vehicle wheel rim such that said pressure members face a discontinuity in the rim; c) securing said presser to the wheel rim with a securing device including a member that extends over said presser and a member that engages an opposite side of said wheel rim through a center hole in said vehicle wheel rim; d) operating said device to press against the discontinuity to reshape the rim. - View Dependent Claims (9, 10, 11)
