Abstract
A drive apparatus includes an electrical motor, a power supply unit, a transmission mechanism, a rail part, and an encapsulating part. The drive apparatus is moveable between a first position and a second position and adjustable in these positions and in any position between these positions. The rail part and the encapsulating part are connected to each other in a heat-conducting connection. A method for operating the drive apparatus includes the steps of changing from one operational mode to another mode and subsequently moving the drive apparatus to a desired position.
Claims7
A screening device for positioning a screening material, comprising:
- a moveable drive apparatus for moving a screening material from proximate a first position to proximate a second position, the moveable drive apparatus including a drive mechanism in a first or a second state and an encapsulating part, the moveable drive apparatus being configured to be manually or automatically adjustable to the first and second positions, or to a desired position therebetween, at least a portion of the encapsulating part being disposed about and connected to at least a portion of the drive apparatus, wherein the moveable drive apparatus, when manually adjusted, is configured to disrupt a power-transmitting connection with the drive mechanism thereby changing the drive mechanism from the first state to the second state and wherein the drive mechanism is adjusted from the first state to the second state by disengaging a drive wheel of the drive mechanism from a guide rail of the screening device.
A method of operating a screening device to position a screening material, the method comprising the steps of:
- adjusting a screening material with a moveable drive apparatus from proximate a first position to proximate a second position, the moveable drive apparatus including a drive mechanism in a first or a second state and an encapsulating part, the moveable drive apparatus being adjustable to the first and second positions, or to a desired position therebetween, at least a portion of the encapsulating part being disposed about and connected to at least a portion of the drive apparatus;
- and
- manually adjusting the moveable drive apparatus to disrupt a power-transmitting connection with the drive mechanism, thereby changing the drive mechanism from the first state to the second state;
- and
- adjusting the drive mechanism from the first state to the second state by disengaging a drive wheel of the drive mechanism from a guide rail of the screening device.
