Automatic door assembly and door operator therefor

A door operator controlling movements of a door panel between open and closed positions, said door operator comprising:

• a rotatable operator output member, said operator output member being operatively connected with the door panel such that rotation of said output member moves said door panel between the open and closed positions thereof;
• a housing having an opening providing access to the interior of said housing;
• and
• a motor disposed within the interior of said housing in operating position wherein said motor is coupled to said operator output member such that operation of said motor rotates said output member so as to move said door panel between an open and closed position thereof, said motor and said opening of said housing being configured with respect to one another to enable said motor to be moved out of said operating position thereof outwardly through said opening for servicing of said motor without disassembling said housing, said motor and said opening of said housing being configured with respect to one another to enable said motor to be moved inwardly through said opening to reposition said motor in the operating position thereof within said housing interior;
• wherein said housing is formed from two housing halves assembled together.

A swing door operator controlling pivoting movements of a door panel that pivots about a generally vertical door axis from a closed position through a range of open positions, said swing door operator comprising:

• a rotatable operator output member operatively connected with the door panel such that rotation of said output member pivots the door panel about the door panel axis thereof;
• a motor coupled to said operator output member such that operation of said motor rotates said output member so as to move said door panel through said range of open positions thereof,
• a first stop member operatively connected to said operator output member such that rotation of said output member rotates said first stop member;
• and
• a second stop member mounted adjacent said output member, said second stop member being constructed and arranged such that said first stop member engages said second stop member during rotation of said output member so as to prevent further rotation of said output member, thereby limiting a range of rotational movement of said output member and thus limiting the range of open positions through which the door panel pivots,
• said first and second stop members being constructed and arranged to be adjustably moved relative to one another through a range of adjusting positions and fixed in a selected one of said range of adjusting positions, thereby setting the range through which rotational movement of said output member will be permitted and thus setting the range of open positions through which the door panel pivots.

An automatic swing door assembly installed in a wall of a building having an opening formed therethrough, said assembly comprising:

• a frame assembly mounted at the opening of said wall;
• a door panel pivotally mounted to said frame assembly for pivotal movement about a generally vertically extending door panel axis between a closed position obstructing passage through the opening of the wall and an open position permitting passage through the opening of the wall;
• a swing door operator comprising:
• a rotatable operator output member operatively connected with the door panel such that rotation of said output member pivots the door panel about the door panel axis thereof;
• a motor coupled to said operator output member such that operation of said motor rotates said output member so as to move said door panel through said range of open positions thereof,
• a first stop member operatively connect to said operator output member such that rotation of said output member rotates said operator stop member;
• and
• a second stop member mounted adjacent said operator stop member, said second stop member being constructed and arranged such that said first stop member engages said second stop member during rotation of said output member so as to prevent further rotation of said output member, thereby limiting a range of rotational movement of said output member and thus limiting the range of open positions through which the door panel pivots,
• said first and second stop members being constructed and arranged to be adjustably moved relative to one another through a range of adjusting positions and fixed in a selected one of said range of adjusting positions, thereby setting the range through which rotational movement of said output member will be permitted and thus setting the range of open positions through which the door panel pivots;
• an input device operable to transmit a door opening signal in response to detecting a presence of an object adjacent said door assembly;
• and
• a controller communicated to said input device, said controller being operable to receive said door opening signal from said input device and to responsively control operation of said motor so as to affect door opening movement.

A swing door operator in conjunction with a controller for which controls pivoting movements of a door panel that pivots about a generally vertical door panel axis from a closed position through a range of open positions, said swing door operator comprising:

• an outermost housing;
• a rotatable operator output member extending outwardly from said housing, said output member being operatively connected with the door panel such that rotation of said output member pivots the door panel about the door panel axis thereof;
• a motor disposed interiorly of said housing, said motor being coupled to said operator output member such that operation of said motor rotates said output member so as to move said door panel through said range of open positions thereof, said motor being communicable with said controller to enable said controller to control operation of said motor;
• a contact switch mounted exteriorly of said housing and being communicable with said controller such that contacting said switch transmits a contact signal to said controller;
• and
• a contact member mounted exteriorly of said housing adjacent said contract switch and providing a contact switch contacting surface, said contact member being operatively connected to said output member such that rotation of said output member to pivot the door panel through its range of open position affects movement of said contact member through a corresponding range of contact member positions, said contact member being constructed and arranged to contact said contacting surface thereof with said contract switch during movement through said range of contact member positions so as to cause said contact switch to transmit said contact signal to said controller, thereby indicating a corresponding position of said door panel in said range of open positions thereof to said controller for use in controlling operation of said motor;
• said contact member being adjustable relative to said output member from the exterior of said housing to enable the position within said range of contact member positions at which said contact surface of said contact member contacts said contact switch to be selected with respect to the range of open positions of said door panel.
