Door stop

A door stop for preventing damage to a surface by a door knob of a door, the door stop, comprising:

• a support surface extending along an axis and having a first end connectable to the surface and a second opposite end, the support member including an inner surface and an outer surface;
• a generally flat deflection member extending radially from the second end of the support member towards the axis, the deflection member deflectable between a non-deflected position and a deflected position in response to engagement thereof by the door knob;
• and including a generally disc-shaped element having a radially outer edge interconnected to the biasing structure and a radially inner edge;
• a frusto-conical wall extending along the axis and having inner and outer surfaces, a first end operatively connected to the radially inner edge of the deflection member, and a second opposite end closed by an, end wall which is longitudinally spaced from a plane passing through the first end of the support member when the deflection member is in the deflected position so as to define a gap therebetween, wherein the inner surface of the frusto-conical wall defines a locking element receiving recess for receiving a portion of a door looking element upon engagement of the deflection member by the door knob and wherein the outer surface of the frusto-conical wall and the inner surface of the support member define a void therebetween;
• a rib interconnected the radially inner edge of the disc-shaped element and the first end of the frusto-conical wall;
• a biasing structure interconnecting the deflection member and the second end of the support member.

A door stop for preventing damage to a surface by a door knob of a door, the door stop, comprising

• a generally tubular support member extending along an axis and having first and second opposite ends and inner and outer surfaces;
• a generally flat plate having a radially outer edge and a radially inner edge, the plate deflectable between a non-deflected position and a deflected position in response to engagement thereof by the door know;
• a biasing structure interconnecting the plate and the second end of the support member, the biasing structure urging the plate towards the non-deflected position;
• a frusto-conical wall extending along the axis and having first and second opposite ends and inner and outer surfaces, the first end of the frusto-conical wall interconnected to the radially inner edge of the plate;
• an end wall closing the second end of the frusto-conical wall, the end wall being axially spaced from a plane passing through the first end of the support member when the plate is in the deflected position;
• and
• a connection flange extending from the first end of the support member, the connection flange connectable to the surface;
• wherein the inner surface of the support member and the outer surface of the frusto-conical wall define a void therebetween.
