Drive for up and over door - has driven chain within slotted profile and carriers and switch actuators

摘要

The drive is used for operating an up and over door situated parallel to ceiling in open position. The drive has endless chain driven by electric motor. The chain spans are guided by a profile with longitudinal slots. Through latter projects a carrier guided in the profile. The opposite side walls (1a) of the carrier have projections (3) in contact with the chain. The side walls (1a) are spaced apart to the width of the chain. The switch actuator is designed in the same manner as the carrier (1). The bottom of carrier (1) has vertical hole for coupling pin (19).
