Claim Text:
1. A door catch, comprising: a ball plunger assembly including a body with a threaded exterior, a bottom surface with a tool receiving pattern and an interior cavity open to a top portion of the body, and a ball captive within the interior cavity and biased by a spring to partially extend out of the top portion of the body; a catch bar bracket including a first mounting portion, a catch bar integrally formed with the first mounting portion and projecting away from the first mounting portion, the catch bar including a first planar surface in which a detent is formed; a ball catch base including a second mounting portion and a base portion, the base portion including a base portion end outer surface distal from the second mounting portion and radiused about a vertical axis and a second planar surface projecting away from the second mounting portion to the base portion end outer surface with a threaded aperture therethrough, the ball plunger assembly threaded into the threaded aperture with the ball extending out of the second planar surface; the catch bar bracket and the ball catch base being mountable on opposing vertical surfaces of a wall structure and a door by the first and second mounting portions so that the ball and the detent frictionally engage to hold the door in an open position, wherein when the ball and the detent are frictionally engaged with one another, the first planar surface and the second planar face one another and are parallel to each other while extending orthogonally to a corresponding one of the opposing vertical surfaces of the door and the wall structure; and a force of impinging of the ball against the detent is adjustable by rotating the body within the threaded aperture, causing the ball to raise or lower with respect to the second planar surface.
