Greenhouse or warehouse, has drive devices connected to screen profiles via sliding clamps with just one pin

摘要

The sliding clamp (10) for the greenhouse screen only includes one pin and also includes a blocking mechanism located at a distance from this pin and used to prevent the clamp from rotating relative to the pin. The screen comprises screen cloths (7), screen profiles (8), sliding clamps and drive devices (9) connected to the profiles via the clamps. Each cloth has one end which is fixed relative to a beam (2) in the greenhouse frame and the other end is secured to a profile, which is used to move the cloth between a closed position extending between two beams and an open position in which it is pressed against the beam at the opposite end to the profile. The clamp is spring-loaded in order to cooperate with a drive device for moving the profile and includes a fastener device (25) for securing it to this profile. The fastener device includes a pin with one end which can cooperate with the profile and another end provided with a clamping means (28) for fixing the clamp to this profile.
