Abstract
Abstract The invention relates to a combination door stop and catch in the form of a molded unit adapted for mounting to the wall surface behind a door in its open position, and adapted, not only to function as a stop for the door before the knob of the door can engage such wall, but to perform the additional function of a catch, to preclude self closing of the door. The catch offers limited though essential restraint for this purpose, but enables automatic release of the door in response to application of force to the door in the direction of closing.

Claim 1
Independent Claim
209 words
A combined door stop and catch comprising a flexible bracket arm having means at one end for use in affixing said arm to a wall with said arm extending substantially normal to such wall, said arm, at its opposite end having a downwardly extending tongue, said tongue having a substantially arcuate downwardly tapering frontal surface and a steeper rearward camming surface, said arm at an intermediate location thereon, having a depending stop spaced from said tongue by a distance sufficient to receive the edge of a door with which the combined door catch and stop is to be used and spaced from said mounting means a distance slightly in excess of the length of a door knob on such door, whereby when affixed to a wall in the path of an opening door and at a location in line with an edge of such door, said door, in engaging the downwardly tapered surface of said tongue will flex said arm sufficiently to enter the space behind said tongue and engage said stop to preclude contact of such door knob with such wall, said door being precluded from self closing by said tongue functioning as a catch, said arm, mounting means, tongue, and stop being molded as a unitary structure.
