Abstract
Abstract A fixed support is formed with a toothed, concave surface releasably engaging a cooperating convex portion of an angularly adjustable member. The convex surface is dimpled and a resilient coupling urges the convex surface to the concave surface for locking engagement. The angular relationship is changed by temporarily separating the toothed surface from the dimpled surface, changing the angle of the member and then releasing the member to return it to a locked position. The bracket assembly is particularly useful for mounting rear-view mirrors and the like.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
156 words
An angularly adjustable coupling, comprising a. a relatively fixed first member, b. a relatively movable second member, and c. resilient means urging said members into releasable engagement with one another including a relatively movable sleeve telescoped over said first and second members and a coil spring mounted within said sleeve and engaging one of said members and said sleeve, said sleeve engaging the other of said members, d. one of said members being formed with a convex portion and the other being formed with a cooperating seat portion releasably engageable with said convex portion, e. one of said seat portion and said convex portion being formed with at least a plurality of protuberances and the other being formed with spaced indents to releasably receive said protuberances, f. said members being free for temporary separation by pulling said members apart against the force of said resilient means whereby the angular relation of said member may be altered.
Claim 2
Dependent Claim
156 words
An angularly adjustable coupling, comprising a. a relatively fixed first member, b. a relatively movable second member, and c. resilient means urging said members into releasable engagement with one another including a relatively movable sleeve telescoped over said first and second members and a coil spring mounted within said sleeve and engaging one of said members and said sleeve, said sleeve engaging the other of said members, d. one of said members being formed with a convex portion and the other being formed with a cooperating seat portion releasably engageable with said convex portion, e. one of said seat portion and said convex portion being formed with at least a plurality of protuberances and the other being formed with spaced indents to releasably receive said protuberances, f. said members being free for temporary separation by pulling said members apart against the force of said resilient means whereby the angular relation of said member may be altered.
