Abstract
A bead depressor for use upon fitting or removal of a tire whereby a tire bead is held in a well base of a wheel comprises a plurality of depressor elements connected together by a cable, and a clamping bar which can be arrested in a centering bore in the wheel. The first depressor element which in use is fixed on the rim flange of the wheel is connected to the clamping bar by a holding rod member and an additional elastic clamping element is operative between the clamping bar and the first depressor element to urge the latter substantially radially against the rim flange and to tilt the clamping bar to arrest it in the centering bore in the wheel.
Claims24
A bead depressor for mounting or removing a tire with respect to a wheel, comprising:
- a plurality of depressor elements including a first depressor element;
- a cable coupling said plurality of depressor elements together;
- a clamping bar adapted to be disposed and operable in a centering bore in said wheel with a portion of said clamping bar projecting from said wheel;
- a holding member operationally coupling said first depressor element to said clamping bar;
- and
- a clamping element operatively disposed between said first depressor element and said portion of said clamping bar,
- wherein when said clamping bar is disposed in said centering bore, said clamping element is operable to urge said first depressor element substantially in a radial direction against a rim flange of said wheel to engage said first depressor element on the rim flange.
