Brake shoe with spring brake member

A brake assembly for locking a slidable sash window within a track of a frame, the track having a pair of spaced apart, opposed sidewalls, the assembly comprising:

• a slider body adapted for slidable motion within the track, the slider body having a central opening extending from a front face to a rear face of the slider body and having a side opening adjacent to the central opening;
• a brake member comprising a spring having an end portion having a first segment and a second segment, the first segment curving inwardly and the second segment curving outwardly and having a curved braking surface thereon, the brake member mounted within the slider body such that the end portion is adapted for reciprocal lateral movement through the side opening;
• a cam positioned in the central opening;
• wherein the slider body is adapted to receive the brake member and the cam is adapted to be rotatable in the central opening for laterally biasing the end portion for said movement through the side opening wherein the curved braking surface is adapted to frictionally engage one of the opposed side walls.

• a brake member comprising a spring having a pair of distal ends, at each distal end having a tip and a convex braking surface adjacent the tip at each, the brake member mounted within the slider body such that each convex braking surface is adapted for reciprocal lateral movement through a respective one of said side openings;
• a cam positioned in the central opening;
• wherein the slider body receives and retains the brake member and the cam is rotatable in the central opening for biasing the convex braking surfaces into frictional engagement with the opposed side walls.

• a slider body adapted for slidable motion within the track, the slider body having a central opening extending from a front face to a rear face of the slider body and having a pair of side openings adjacent to the central opening;
• a brake member comprising a spring having a base portion and two end portions, each end portion having a first segment curving inwardly and a second segment curving outwardly and having a convex outer surface, each end portion having a braking surface located on the convex outer surface of the second segment with each braking surface having a plurality of serrations thereon extending from the second segment, the brake member mounted within the slider body such that one of the respective braking surfaces is adapted for reciprocal lateral movement through a respective side opening;
• a cam positioned in the central opening;
• wherein the slider body receives and retains the brake member and the cam is rotatable in the central opening for laterally biasing the one of the braking surfaces for movement through said respective side opening wherein the one of the braking surfaces is adapted to fictionally engage a respective one of the opposed side walls.
