Abstract: A door holder assembly used to maintain a door in an opened position. The assembly is made up of a door stop, a locking plate mounted on the door and a floor mounted door holder. The door stop and the door holder are fixed to the floor while the locking plate is fixed to the lower portion of the door and is positioned to engage the door holder when the door is opened. The locking plate has two joined segments one of which is planar and flat while the other of which has a right angled groove. Depending on the vertical elevation of the door's bottom above the floor, the same locking plate can be mounted to the door in one of two different positions. If the elevation is slight then the right angled groove portion is mounted on the vertical front door surface. If the elevation is larger and sufficient space exists, the locking plate may have the right angled groove portion mounted to the lower edge of the door between the door and the floor.

Abstract: A door security device allows partial opening of a door by coupling a door to a floor structure. The coupling is provided by a door bar including first and second length portions in spaced, parallel relation. The first and second length portions are interconnected by a coupling portion perpendicular thereto. One length portion is pivotally mounted in a floor on the inside of a doorway. The other length portion then assumes an upstanding vertical position. As the door opens, the door engages the upstanding length portion and moves towards an open position so long as the door bar permits. Eventually, the door bar blocks further opening of the door and maintains the door in a secure condition despite partial opening. In a second mode of use, the door bar is reoriented and inserted within the pivotal mounting of the floor to pin the door shut in closed condition. The door security device offers advantage in its ease of installation and use, low cost, and effective security against forced entry.

Abstract: A doorstop including an elongated shaft slidably and rotatably received within a receptacle seated in a floor proximal a door. The shaft extends vertically from the receptacle and has a cross-member integrally connected thereto and extending therefrom in opposing lateral directions such that the door, when opened toward the shaft, will contact the cross-member and rotate the cross-member into planar contact with the door. Thus, the movement of the door will be limited by the shaft and laterally extending cross-member. In a separate embodiment, end portions are integrally connected to the cross-member which project generally horizontally therefrom. When the end portions are facing or protruding toward the door, movement of the door from its closed position is completely obstructed. This embodiment functions as the original embodiment described above when the end portions are facing away from the door.

Abstract: A door stop is formed from a single flexible band of sheet metal which is symmetrical about a transverse center line and includes an arch shaped central section and two end portions. An underside of one end portion includes a high friction material while the underside of the other end portion is free from that material. The only engagement with the door is provided by the frictional engagement of a high friction material on a center section engaging the bottom edge of the door. The device can thus be used from either direction and provides a symmetrical force on the door preventing movement relative to the stop in either direction.

Abstract: A door stop adapted for a mounting adjacent a lower edge of a door at a location remote from the hinge, such door stop functioning to prevent an intruder from pushing the door open. This door stop comprises a mounting device adapted to be secured in a fixed position adjacent the lower edge of the door, and an elongate, rigid member operatively associated with the mounting device. One end of the elongate, rigid member has an aperture, enabling it to be pivotally mounted to the mounting device, and the other end of the elongate, rigid member has a component adapted to move, at the behest of the user, into contact with the floor. The elongate member is selectively movable between a raised, substantially vertical storage position residing close to the door, and an active, downwardly angled position in which the other end is in firm contact with the floor. I advantageously utilize a spring bias arrangement serving to hold the other end of the elongate member in such position of firm contact with the floor.
