Abstract
A door opener assembly having a rotatable arm-bar for hands-free use by individuals in high-traffic pedestrian conditions. The rotatable arm-bar has a distal knobbed end and allows users to easily position a wrist or forearm within the hook and to move laterally, as the person moves, as the door is opened and thereafter provides a slide-release of the forearm or wrist. The smooth surface and design of the arm-bar allows users to disengage from contact without risk of injury occurring such as from the unexpected opening of the door from the opposite direction.
Claims12
A door opener assembly for attachment to a side of a hinged door to which a hands-free pulling force can be applied to swing open said hinged door said door opener assembly comprising:
- a support for attachment to the side of the hinged door requiring a pulling force to swing the hinged door open;
- an arm-bar comprising a proximal shank portion rotatable about its longitudinal axis and connected to said support, a bend portion having a distal end extending from said shank portion, said distal end displaceable along an arc of about 160 degrees;
- at least one magnet operatively mounted to said arm-bar and at least one magnet stationarily mounted to said support, said magnets positioned to bias said arm-bar to an initial position along said arc of about 160 degrees;
- and,
- when said support is attached to the side of the hinged door, said shank portion extends downward and parallel to the side of the hinged door and said distal end travels in a substantially perpendicular plane relative to the side of the hinged door when a pulling force is applied to said arm-bar and returns said arm-bar to said initial position when the pulling force is released.
A door and door opener assembly comprising:
- a door having an inner hinged edge and a laterally spaced outer swinging edge, and generally parallel faces extending between said edges;
- said door having a first parallel face to which a pulling force is applied to swing open said door;
- and a second parallel face to which a pushing force is applied to swing open said door;
- a support housing operatively attached to said door face to which a pulling force is applied to swing said door open;
- an arm-bar comprising a shank portion rotatably mounted to said support housing, a bend portion extending from said shank portion, said bend portion having a distal end;
- said shank portion extending from said support housing and parallel to the parallel faces of the door;
- and,
- said shank portion rotatable about its longitudinal axis from a first position where the distal end of said arm-bar is located about 40 degrees from the inner hinged edge of the door to a second position where said arm-bar is located about 180 degrees from the inner hinged edge of the door, and
- at least one magnet operatively mounted to said arm-bar and at least one magnet stationarily mounted to said support housing, said magnets positioned to bias said arm-bar to an initial position;
- and, when said support housing is attached to the side of the door, said shank portion extends downward and parallel to the side of the door and said distal end travels in a substantially perpendicular plane relative to the side of the door when a pulling force is applied to said arm-bar and returns said arm-bar to said initial position when the pulling force is released.
