Abstract
A narrow door opener which has a capability of being mounted in a small space between the end of a door roll of, for example, a curtain door and any impediment spaced therefrom. The door opener has on its flank a waisted region to accommodate a mounting bracket below the axle axis of the door roll to be opened thereby. The flank to flank distance (not counting door roll engagement features) is less than 200 mm and preferably less than 100 mm.
Claims26
A door opener which has a capability of being mounted in a small space between the end of a door roll of, for example, a curtain door and any impediment spaced therefrom, such door opener having provision whereby, despite its need for mounting and/or its lateral extent in the direction of the rotational axis of its output drive member, is and will be less than 200 mm.
A door opener of a kind having a rotatable output member adapted to engage a door to be opened or closed, said output member having an axis of rotation which in use will be at least substantially horizontal and transverse to the longitudinal extent thereof which is in use will be substantially vertical,
- wherein the opener has its transverse extent in that direction parallel to said axis of rotation less than its transverse extent normal thereto and less than its longitudinal extent,
- and wherein on that flank of the opener opposite the flank with the output member there is a waisting at a region adapted to receive a or the mount for the opener.
A door opening arrangement including
- a (cored, spooled, axled or equivalent) curtain door assembly capable of being rotatably unwound and wound, thereby to close and open respectively a door opening of a building,
- a door opener engaging an end of the curtain door assembly capable of being initiated to cause the curtain door assembly to unwind and/or wind, and
- a mount for the door opener from the building
- wherein the door opener has a lateral parallel to the wind/unwind axis of the curtain door assembly less than 150 mm.
A door opener adapted to open and/or close or allow to close a curtain door, the door opener having at least:
- at least partial housing assembly that includes support (directly or indirectly) for the remaining features (“the assembly”),
- a sun gear carried by the assembly,
- a drive member or members to rotate as the sun gear rotates and adapted externally of the assembly to engage and to rotate a complementary door curtain assembly,
- a pinion adapted to rotate the sun gear,
- an electric motor,
- a transmission from the motor to the pinion by which the pinion rotates responsive to motor movement, and
- control and limit functionalities for the motor, the transmission and/or the sun gear/pinion interaction whereby the drive of the sun gear, one way and/or the other in a rotational sense, and (optionally) the limiting of rotation thereof in at least one rotational sense, is caused, allowed and/or controlled by (a) signal inputs alone or (b) a mixture of set up input(s) and signal input(s),
- wherein the assembly allows for an inset support thereof (e.g. by a complementary mount) at least in part under part of the assembly when, as is desired, the sun gear of the door opener is to be oriented such that it rotates about a substantially horizontal axis,
- and wherein the greatest dimensional extent of the opener in a direction parallel to the rotational axis of the sun gear from the exterior of the sun gear (ignoring the drive member(s)) to 15 the other side of the opener is less than 150 mm.
A door opener adapted to open and/or close or allow to close a curtain door, the door opener having at least:
- at least partial housing assembly that includes support (directly or indirectly) for the remaining features (“the assembly”),
- a sun gear carried by the assembly,
- a drive member or members to rotate as the sun gear rotates and adapted externally of the assembly to engage and to rotate a complementary door curtain assembly,
- a pinion adapted to rotate the sun gear,
- an electric motor, and
- a transmission from the motor to the pinion selectively by which the pinion rotates responsive to motor movement,
- wherein the assembly allows for an inset support thereof (e.g. by a complementary mount) at least in part under part of the assembly when, as is desired, the sun gear of the door opener is to be oriented such that it rotates about a substantially horizontal axis,
- and wherein the greatest dimensional extent of the opener in a direction parallel to the rotational axis of the sun gear from the exterior of the sun gear (ignoring the drive member(s)) to the other side of the opener is less than 150 mm.
A door opening arrangement including
- a (spooled or equivalent) curtain door capable of being rotatably unwound and wound thereby to close and open respectively a door opening of the building,
- a door opener engaging in end of the spooled or equivalent curtain door actuable to rotate the door curtain spool or equivalent and
- a mount for the door opener from the building, such mount extending substantially to the door opener in a plane or planes substantially normal to the spool or equivalent axis,
- wherein the greatest extent of the opener (save for any engagement penetrating into the spooled or equivalent curtain door in a direction parallel to the rotational of the spooled or equivalent curtain door) is less than 150 mm.
