Abstract
The invention relates to a rim brake for a bicycle or the like and in which the brake lining can be moved via a pivotally mounted actuating member and a support member which carries the brake lining and is movable at right angles to the rim. The actuating member is rotatable about an axis which may coincide with the axis of displacement of the support member and is connected to the support member via a threaded control such that rotation of the actuating member in one direction imparts axial movement of the support member in a direction to apply the brake lining to the rim.
Claims9
A brake for use with a wheel rim of a wheeled cycle, said brake comprising a pair of housings;
- means for mounting said housings on opposite sides of and adjacent said rim;
- a support slideably but non-rotatably mounted in each of said housings for sliding movements along an axis of displacement in directions toward and away from said rim;
- a brake lining carried by each of said supports in a position to engage said rim;
- a threaded spindle connected to each of said supports for sliding movements therewith;
- a threaded bush mounted in each of said housings for rotation about said axis and in threaded engagement with the associated spindle;
- actuating means coupled to each of said bushes for rotating the latter simultaneously;
- and means reacting between each of said housings and the associated actuating means for preventing movement of the latter longitudinally of said axis, whereby rotation of said bushes effects sliding movements of said supports along said axis.
