    摘要： The present invention provides an improved hold-open device (50) for holding a roll-up door (55, 56) in an overhead out-of-the-way position in a body, the door being mounted for movement within a track (51) having a vertical portion (52), an arcuate portion (53) and a horizontal portion (54). The improved device broadly includes: a plate (62) mounted on one of the track and cargo body; an arm (63) pivotally mounted on the plate; a striker (64) mounted on the door, the striker having an inclined surface (79) and an abutment surface (80); a stop (70) mounted on the arm, the stop having an edge (87) adapted to selectively engage the striker surfaces; and at least one spring (25) urging the arm to move such that the edge will engage one of the striker surfaces.

    摘要： A portable door guard used to secure the door at the hinge, particularly the wings of the hinge. The portable door guard comprises a retractable, non-permanently fixed device that can be secured around the hinge of the door from the inside to prohibit the door to open more than a gap. The portable door guard includes a center area designed to grip the hinge to limit the swinging movement of the hinge and adjusting means to configure the size of the gap.

    摘要： A heavy duty full energy, encoder driven non-handed electric door operator for industrial and commercial use a motor and an encoder configured to receive an external set of predetermined instructions. A motor mounting bracket connects the motor to a multi-layer housing. A controller is in electronic communications with the encoder and transmits external sets of predetermined instructions. Internally, the door operator contains a plurality of transfer shaft assemblies in communication with each other and connected with the motor at one end and an output shaft at the other end. The output shaft terminates at each end in a nondetachable spline. A detachable mounting plate serves as a base. The door operator operates heavy swing doors external to a building where the swing doors are required to be open or remain open in strong wind conditions.
