Door opening and closing apparatus
First Claim
1. An apparatus for opening and closing a door of the type mounted by way of hinges at one outside edge thereof to a door frame, the apparatus comprising;
- an actuator bar having connection means at one end thereof for pivotal connection to one of said door and said frame and having a uniform bar thickness presenting oppositely disposed drive surfaces therealong, and a force generating unit having a framework for affixing said unit to the other of said door and said frame;
said force generating unit comprising;
a carriage assembly mounted on said framework for swivel movement about an axis relative to said framework, a reversible drive motor having a housing supported by said carriage and an output shaft substantially coaxial with the swivel axis of the carriage, a pair of rollers mounted for rotation within said carriage and presenting drive surfaces spaced a distance greater than said thickness of said actuator bar, said output shaft of said motor having a driving connection to at least one of said rollers, and a shifter for rotating said carriage about the pivot axis of said carriage to thereby divert a line extending between the axis of the rollers from being in the perpendicular position relative to a longitudinal axis of the actuator bar and to thus bring said surfaces of said rollers into a pinching contact relationship with said opposite drive surfaces of said actuator bar located therebetween.

Abstract
An apparatus for opening and closing a door remotely includes a remote control infra red (IR) control, a door hinge mounting assembly and a door opening assembly attached to the door. Also included is remote controlled halogen safety light, a battery pack and charger. The apparatus comprises a battery operated DC gear motor which is activated by a digitally decoded signal which opens and closes a door partially or fully using a two button IR transmitter, latching using an internal mechanism. The apparatus is mounted without deforming any of the structure to which it attaches and is installed with one Allan key which is provided with the unit.

19. In an apparatus for opening and closing a door of the type mounted at one outside edge of a door frame by way of door hinges, and wherein said hinges are of a two part type including hinging portions consisting of aligned alternate cylindrical portions of each part and receiving therethrough a headed pivot pin, said apparatus including I) a force generating unit having a framework for affixing said unit to the door, and ii) an actuator bar for interaction with said force generating unit and having at one end a connection portion for pivotally connecting said unit relative to said door frame;
-
the improvement comprising a mounting bracket for attachment relative to said door frame, said mounting bracket including;
a flat plate member having a first elongated portion to be positioned over a vertical side portion of said door frame at said outside edge of said door frame and a second upper elongated flat portion extending from a side edge of said first portion for positioning over a top portion of said door frame, said flat plate member having a bar attachment arm extending outwardly therefrom, said first portion including along an inner side edge thereof an upper outwardly projecting portion for overlying the said headed pin and a lower outwardly projecting portion to underlie said hinge portion of said hinge, upper and lower clamping members carried by said upper and lower projecting portions for engagement with the head of said pin and a lower end of said hinging portion of said hinge, respectively, at least one of said clamping members being adjustable toward and away from said hinging portion to thereby clamp said mounting bracket to said hinging portion and in a position to flatly overlie said vertical side portion of said door frame. - View Dependent Claims (20, 22)
