Abstract:
A top hinged swinging sash assembly includes a hinge bar adapted for securement to a building girt, said hinge bar including a substantially J-shaped hinge rail. A frame assembly comprising a head member, a sill member, two or more vertical mullions and two side flashing members is joined to the hinge bar through a curved, beaded head rail extending from the head member. The spaced, vertical mullions connect between the head and sill members with flat or corrugated panels being retained between the mullions and mullion caps mounted thereto. Operators connect to the frame and preferably to the mullions or sills to cause the frame to swing out from the hinge bar. In a preferred embodiment the mullions include a planar forward surface having a hub extending outward therefrom to define oppositely extending channels. These channels accommodate flat panels or in the case of the end mullions accommodate the side flashing members in interlocking relationship. The operator is preferably a rack and pinion with the rack arm thereof terminating in a pivotal connection with the rear portion of the mullion. The frame members are preferably made of extruded aluminum, extruded plastic or formed sheet metal.
Abstract:
An inertia insensitive disconnectable drive linkage connects a power operator to a swinging door and comprises a door bracket fixed to the door and an arm operator pivoted thereto. A latch positively locks the operator arm to the bracket during normal powered swing of the door. A cam on the door frame releases the latch when the door is swung beyond the door closed position in the opposite direction of opening during emergency operation.
Abstract:
A drive mechanism engaging means is disclosed which may be used for a garage door operator to engage and disengage a chain as an example of a flexible drive member which is driven from a motor and speed-reducing drive train. The engaging means selectively engages and disengages a drive carriage from the chain so that in the event of electrical power failure, for example, the load carriage may be disengaged from the chain so that the garage door, which is fixed to the load carriage, may be manually operated to open and close the door. The engaging means may be actuated by a handle to be moved against a yieldable spring to stress the spring and thus release the load carriage from connection with the chain. The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.

1,009,389. Door operating appliances; sliding doors; hangers; hinges. DOR-WEST Inc. Oct. 17, 1963 [Nov. 19, 1962], No. 41006/63. Headings E1J, E2F and E2M. An entrance is closed by a sliding door or doors supported by carriages running on an overhead track and automatically power operated when a person enters or leaves a traffic area including the entrance, and each door comprises a frame to which is hinged a wicket door arranged to swing outwardly to form an emergency exit. A door assembly 26 supported by carriages 31 running on a track 30 in a head recess 27 extending over the doorway and pockets 25 is moved into and out of the pockets 25 by an arm 34 and link 35 driven by an hydraulic motor 33 accommodated within the pocket 25. The door comprises an L-shaped frame with a header 47 and a joint part 48. A door having top and bottom rails 54-55, and stiles 52-53 with a glass panel 50 is hinged to the joint part 48 by a hinge, Fig. 7, comprising two sets of leaves 56, 56 1 pivoted together at 57. One end of each set is pivoted to a butt block 58, 59 on the door stile or from joint 48 respectively, and the other end of each set has pins 62, 63 sliding in slots in the butt blocks. The header part 47 of the sliding frame has a tongue 66 and groove, Fig. 2, co-operating with a tongue 65 and groove on the top rail 54 of the wicket door to carry its weight when the door is held in closed position by a bullet catch 67. In a modification, Fig. 9, one of a pair of doors is operated by an hydraulic motor, and the other door is operated by cables 140 extending from carriages 132, 133, 134, 135 round pulleys 137, 138 in the head recess 27. In this embodiment the carriages have single wheels running on a rib type rail, Fig. 10, not shown, and carry non-rise rollers. The hydraulic motor or motors are set in motion by electrical switches operated by the depression of carpets 41-42 on either side of the doorway, which set in motion a motor driving a pump in a closed hydraulic circuit with a reservoir and the operating motor.
