摘要： A heated cabinet including door assembly having a door positioned between opposing jambs of a door frame, wherein the door is pivotable, about a pivot axis, between an open position and a closed position. The door assembly includes a motor assembly operably connected to the door to pivot the door about the pivot axis and a control board operatively coupled to the motor assembly. The door assembly further has a first break beam emitter mounted to one of the opposing jambs and a first break beam receiver mounted to another of the opposing jambs and operatively connected to the control board. The first break beam emitter and first break beam receiver are disposed along a beam axis extending parallel to the pivot axis and proximate to an edge of the door adjacent to the pivot axis. The door assembly is configured such that interruption of a beam projected between the first break beam emitter and the first break beam receiver alters operation of the motor assembly.

摘要： Motorized door assemblies having a door pivoting about a pivot axis extending across opposing jambs. In one aspect, the assembly includes a motor assembly having a motor, drive gears, slip clutch, and driven shaft connected to the door to pivot it about the pivot axis. The slip clutch includes a clutch plate slideable along the driven shaft, a drive plate driven by the motor via the drive gears, and a clutch spring urging the clutch plate into engagement with the drive plate, where the clutch and drive plates have profiled and counter-profiled faces. In another aspect, a break beam emitter and receiver are mounted to respective ones of the opposing jambs along a beam axis extending parallel to the pivot axis and proximate to an edge of the door opposite the pivot axis. Interruption of a light beam projected therebetween alters operation of a motor assembly.
