A universal elevating leg rest assembly for a wheelchair. The leg rest assembly includes an upper hanger plate mounted on a front tube member of the wheelchair. A lower hanger plate is mounted on the front tube member in a vertically-aligned, spaced-apart relationship with the upper hanger plate. A universal bracket assembly is pivotally mounted to the upper and lower hanger plates and allows the elevating leg rest assembly to be positioned on either the left or right side of the wheelchair. A latch mechanism allows the universal bracket assembly to be locked in place or unlocked, swung-away and detached from the wheelchair, if desired. A calf clamp assembly is hingedly connected to the universal bracket assembly. A release mechanism including an arcuate-shaped cam surface frictionally engages an arcuate-shaped cam surface of the calf clamp assembly to lock the leg rest assembly at a selected vertical position. Depressing the release knob causes the cam surfaces to no longer frictionally engage each other and unlocks the leg rest assembly from the selected vertical position.
