3Uese arrangement has the disadvantage »that through the use of the Konuafläehenj) the reconciled driver and the spring Establishing such a company is very expensive »because the production of these ÜDeile with the smallest possible gearbox is very iEoaplized * In addition, with this gearbox » just like in the previously described embodiment with the freewheel », the braking forces are absorbed by the housing» whereby this must be carried out particularly carefully.

Such a gear now has the advantage that the force » • flow between the ropes arranged within it closed is. Furthermore, the particularly small design takes this .gear when designed as a bevel gear kausi more space than the arrangement of just two bevel gears without locking device and the like. In addition, there is no separate Arrangement of friction disks »" "

The only result is the storage of the shaft in the housing

In the first pail this bearing is characterized in that the collar "stop or the like" of the shaft is arranged with axial play next to the ratchet on the side facing away from the gear. The other possibility is that the collar, stop, or the like, is arranged at the end of the shaft, and that the collar and the spur wheel with axial play can be rotated and displaced on the shaft and in the gear housing. Shoulder ring is arranged ».

1) 3.3 holding the gear wheel can also be that the handle of the Eahnx'ades can be fixed in the axial direction by a collar, stop or the like located on the inside of the gear housing. '..'... ■

Torque of the pinion shaft 17 via the bevel gear 2 and the by. Friction with one another firmly connected parts are transmitted to the shaft 6 * which form-lock the torque transfers to the blind shaft "

If the upward movement is now stopped, eg if you want to only half cover the penster with the blind, the blind shaft cannot turn back due to the blind's own weight, since the inclined teeth 4a, 4b are still pressed between the collar i? and disk 5 and the parts in between cause »As a result, the ratchet wheel 9 sits practically non-rotatably on the shaft 6, so that the pawl 10, if the blind shaft and therefore also the v / eile 6 rotate counterclockwise (against the arrow in 3? ig.2) locks the shaft.

Do you want. Now lower the blinds again and they come in Flanks of the teeth of the toothings 4a »4b running in the direction of the axis in singular engagement, whereby the torque of the Ritseis 1 over · the bevel gear 2 on the Veraahnung 4a and from this on the Veraahnung'4b is positively transmitted »so that the shutter - it causes the blind to be lowered.

In addition, it should be mentioned that instead of the claw-like teeth 4a, 4b on the Kegslradnabe 3 and on the disk 5, respectively. Thread on the right end of the shaft in Pig »1 Internal thread arranged at the right end of the bevel gear hub 2 ' can be, whereby when moving the?
