L as our window blinds are actually very simple mechanisms. You just need to understand its operation to diagnose any fault and the solution is often very inexpensive and easy to perform.

For a comprehensive lists and explains the picture:

The shutter is a roller (1 ) on which subject the last row of blades of the shutter itself. On one side (either left or right) has a pulley (2 ) with the appropriate size of the tape (3 ) or move the shutter cable.

This tape (on some models is a cable but for that matter) is attached to the pulley or by a screw or through a slot where the tape is inserted and then makes a knot so it can not go back (the most common method).

Tape comes outside the drawers of the blind supported on rollers (4 ) capable of distributing the force so that it will cost less to move the blind, they can go in the top or bottom depending on model . If it is cable, these rolls do not exist and it is driven through a sleeve embedded in the wall to the catcher or drive mechanism.

The No. 5 image refers only to the blind that are manufactured for installation in work, is a metal plate that prevents friction between the blades of the blind and pulley as this type of blind is very Justito of space. While repair when one remembers the mother who designed them. This plate, if you have one, is easily removed with 4 screws, one at each corner.

Besides all this we have the mechanism to collect the tape from the bottom that I will save for another article.

The most frequent breakdowns are usually a shade:
a) - Rupture of the tape, or just change it because it is very spoiled, or on a whim that anything can happen. Solution: change the tape ( see here)
b) - Rupture of a lamina, or deviation from the same place that the blind see fall or twisted. Solution: replace broken sheet and align as necessary (in another article)
c) - catcher spring break, causing the ribbon is lasa and lower the shade alone. solution: replace the pickup mechanism ( see here).

first thing before any repair attempt is to look at the top of the shade to see how it is dismounted. In shades with wooden top, this is attached to the wall with a few screws and paint probably have hidden their heads and will cost some time and skill to locate them.
If the lid is of prefabricated take a couple of screws and then embedded, you only have to look closely and quickly with the way we take on and off.

in subsequent articles will detail the most common solutions and the comments give some detail but who needs it.
