Definitions
- a belt pulley On a tension belt is wound up. From the belt pulley The belt leads approximately parallel to the wall vertically downwards and disappears at the bottom in a wall opening. In the wall opening sits another belt pulley which in Winding direction of the belt biased by a spring is.
- the wall opening in which the second spring-loaded Belt pulley is mounted, is outward through a cover plate closed, only for the passage of Belt contains a slot.
- a arranged in the cover plate brake mechanism makes it possible to clamp the belt, so he counter the effect of gravity in any open position can be held.
- the brake and locking mechanism works in dependence on the direction of force in the Strap and it is loosened by the strap in the area of Locking mechanism in a position approximately perpendicular to the Wall surface is brought.
- Gurtwicklerantriebsaggregat known is to be installed later.
- This Gurtwicklerantrieb consists of a two-part housing, in which Housing base parallel and spaced from each other two Friction rollers for the webbing are arranged.
- the Drive motor Next the front side of one of the friction rollers is the Drive motor, which has an angular gear with the friction roller is coupled.
- the friction rollers are non-rotatable connected with spur gears.
- the geared Coupling between the bearing in the lower part friction rollers takes place with a further friction roller, the is rotatably disposed in the upper housing part.
- the roll loading belt runs Meandering between the in the housing base and the in the upper housing part rotatably mounted rollers, wherein two more, stored in the lid rollers Turn the belt in such a way that, viewed from the outside, it seems to be just passing through the housing.
- the housing is asymmetrical with respect to the running direction of the belt, i.e. it overhangs the belt to one side. Accepted the housing overhangs the belt to the right, the supernatant must be at a right of the window not disturb the running belt, but it can be annoying when the belt runs to the left of the window.
- the housing protrudes then possibly with the protruding part in the Window opening into it, which is not a particularly beautiful aesthetic Effect results.
- the special design of the board and the place one of the friction rollers or a loose roller that when mounted Roll-loading belt drive the Locking and braking mechanism for the roll loading belt except Operation is set.
- a corresponding in the board Exit slot for the strap provided and designed so that the slot is open at the side to disassemble the Belt to mount the new drive.
- the coupled via gears slip-free with each other Friction rollers ensure a particularly slip-resistant Drive of the belt. Due to the positive coupling The friction rollers will be the friction surface over which the belt is in contact with the friction rollers, enlarged, what with resting friction to an enlargement of the possible Mit Spotifykraft and thus given a force to one diminished slip leads. It can not individual friction rollers to lose the static friction with the belt.
