Abstract

A door holder including a receptacle unit adapted to be mounted on a wall and having a plastic body member with an outwardly opening central axial cavity, and a plunger unit adapted to be mounted on a door and having an elongated shank with an outer end releasably interengageable in the cavity of the body member.

Claims

1. A door holder for releasably and selectively maintaining an open swingable door in spaced relation along a wall comprising a receptacle unit including a metal cup member and an elastic body member having formed in its inner end an annular recess to define an outer ring portion and a concentric inner ring portion, where the inner face of said inner ring portion is disposed inwardly of the inner face of said outer ring portion, said outer ring portion is seated in said cup member, an outwardly opening central axial cavity formed in said body member and extending through a substantial part of the length of said inner ring portion, an axial opening formed from the inner end of Said cavity to said inner face of said inner ring portion and in registry with an aperture formed in said cup member, and a fastener having a head engaging the inner end of said cavity and extending through said axial opening and said aperture for mounting said receptacle unit on one of said wall or door, and a plunger unit adapted to be mounted on the other of said wall or door and including an elongated shank having an outer end releasably interengageable in said cavity of said body member.

2. The door holder of claim 1 wherein said cavity of said body member is formed with an annular throat zone adjacent the outer end thereof, and wherein said outer end of said shank is semi-spherical with a diameter slightly greater than the diameter of said throat.

3. The door holder of claim 1 wherein said cavity of said body member is formed with a spherical zone immediately inwardly of said throat zone for conformably receiving said outer end of said shank, and wherein the section of said shank adjacent said outer end thereof has a smaller diameter than that of said outer end of said shank whereby an annular shoulder is defined for releasable engagement behind said throat zone.

4. A door holder for releasably and selectively maintaining an open swingable door in spaced relation along a wall comprising a receptacle unit including a metal cup member and an elastic body member having formed in its inner end an annular recess to define an outer ring portion and a concentric inner ring portion, where the inner face of said inner ring portion is disposed inwardly of the inner face of said outer ring portion, said outer ring portion is seated in said cup member, an outwardly opening central axial cavity formed in said body member and extending through a substantial part of the length of said inner ring portion, an axial opening formed from the inner end of said cavity to said inner face of said inner ring portion and in registry with an aperture formed in said cup member, and a fastener having a head engaging the inner end of said cavity and extending through said axial opening and said aperture for mounting said receptacle unit on one of said wall or door, where the diameter of the outer end of said cavity decreases as said fastener is tightened to proportionally increase the holding force of said receptacle unit, and a plunger unit adapted to be mounted on the other of said wall or door and including an elongated shank having an outer end releasably interengageable in said cavity of said body member.

5. The door holder of claim 4 wherein said cavity of said body member is formed with an annular throat zone adjacent the outer end thereof, and wherein said outer end of said shank is semi-spherical with a diameter slightly greater than the diameter of said throat.

6. The door holder of claim 5 wherein said cavity of said body member is formed with a spherical zone immediately inwardly of said throat zone for conformably receiving said outer end of said shank, and wherein the section of said shank adjacent said outer end thereof has a smaller diameter than that of said outer end of said shank whereby an annular shoulder is defined for releasable engagement behind said throat zone.
