There are many types and options to darken a room. A variant is the rollover. A rollover is a form of Sun protection, this is the glass doors or Windows and where mostly wrapped a rectangular fabric on a wave.
Another form is the folding shade, where folded the cloth raising instead is rolled up. There are blinds in various types, degrees of transparency, colors, patterns, sizes and shapes. Even triangular or trapezoidal shapes for blinds are feasible in some part. The types of blinds can be used are different. There is the possibility the blind through a chain hoist to use.

You want the blind to stay below, you must ensure that the spring locks. This can be done by gently stop of the blinds at the desired height. According to the spring can be solved again with a ruckhaften movement, wants to get again wind up the blind. This control type requires some patience.
