EP1717410A2 - Method for avoiding damage of hangings - Google Patents

Abstract

The method involves regulating positions of hangings in a building based on a stored data and actual atmospheric measured values and using a controller. The positions are changed manually or by an automatic unit only in an operating range. Inclination of each hanging is adjustable in an angle limited by the controller. The hangings can be raised/lowered within a storm-resistant extended height, during exceeding of a given wind velocity.

Description

The invention relates to a method for preventing damage to hangings according to the preamble of patent claim 1.

Hangings, such as slats, blinds, awnings, etc. are operated either manually or by electric drives, ie moved up or down, and set in slat blinds in addition the inclination of the slats. Controls are also known which detect atmospheric data, such as wind speed, position of the sun, temperature, etc., in order to protect the hangings against storm winds, for example, by raising them, or to control the incidence of light depending on the position of the sun. These dependent on external influences operations of the hangings are made fully automatically. However, the user is in most cases an influence on a manual or remote control available, manually triggered to change the slat position, for example, the room by adjusting the inclination of the slats more or to darken less or to raise or lower the blind completely or partially. As a result, although the curtain was raised due to high wind speeds by the automatic control to protect it from damage, but this can still be damaged because an operator manually exposes the curtain by hanging down the wind forces again. But less serious measures can be brought about manually, if, for example, by the automatic control, the slats of a curtain are inclined so as to ensure optimum use of light, but to prevent the direct entry of sun rays, but then by manually made changes the slats in one Inclined position are brought, which darkens the room so that in this by another automatic control, the lighting is turned on. It can enter directly through a manually set inappropriate angle of inclination sunlight, which means that the inevitably higher heat output forces the air conditioning to a greater cooling capacity.

An object of the present invention is to provide a method by which manual mishandling and / or mishandling of subordinate automation on automatically operated hangings and windows can be prevented.

This object is achieved by a method having the features of patent claim 1.

It is possible by the control-side restriction of the driving ranges to reduce manual access and / or automatic accesses of a subordinate automatic to predetermined positions in order to protect hangings from damage and exclude unsuitable Behangstellungen, which cause greater energy consumption or other possible disadvantages for the user.

The invention will be explained in more detail with reference to some embodiments.

example 1

A store with electromotive drive is provided with a controller which is connected to an anemometer. When a predefinable maximum wind speed (storm) is exceeded, the store is wholly or partially pulled up, thus reducing the surface area of the wind. With the manual control, the store could no longer be used in conventional systems. According to the invention, this is now prevented by the fact that the user or the subordinate automatic can lower the store only over an upper partial area and can only bring it into an inclined position, which in the Tolerance range and strong wind is able to withstand optimal. The manual and subordinate automatic driving range of the store is thus inevitably restricted by the control to a store protecting the damage section.

In a particularly advantageous embodiment of the invention, for example, at a wind speed of 40 km / h, the curtain can be pulled up in half and the operator still has manual adjustments available within this range. In addition, the automatic shading can also drive in the upper area. If the speed increases above 60 km / h, the curtain is pulled all the way up and the operator is completely deprived of any manual or subordinate automatic intervention.

Example 2

For reasons of energy efficiency, the slats of the store are tilted so that no direct radiation can enter the room. Particularly comfortable controls always take into account the current position of the sun and / or the brightness. According to the invention, the user has possibilities of intervention only insofar as he can increase the lamella inclination, so that less light can enter the room. He is denied a manual Slat position, which allows the direct passage of sunlight. This would cause the room to be additionally heated up and, if present, to put automatic recooling into operation by an air conditioning system.

Example 3

In office buildings with tilt windows, there is the latent risk that a collision will occur between the outwardly swung area of the window and the curtain. The automatic blind control avoids such, because the angle of inclination of the window is passed on to the control by means of suitable sensors, so that the blind is lowered only so far that no collision takes place. It is manually only possible for the user or the subordinate automation system to raise the curtain upwards, i. away from the collision point. The automatic shading system can also only drive in the upper area.

Example 4

If the slats are brought by Storen for cleaning in a suitable position, the user can move during the cleaning time, the slats only within an angle of inclination, which is greater than the predetermined by the control angle suitable for cleaning. A closing of the slats is so locked out. Closed louvers prevent the cleaning of the entire rear of the louvre. The subordinate automatic is completely blocked in this case.

Example 5

Similarly to hangings, windows can also be opened in whole or in part by an automatic control system for controlled ventilation. According to the invention, the opening angle can now be adjusted by the automatic control as a function of the wind speed and / or the outside temperature. Manual intervention is then only possible to a limited extent, namely to close the window, i. to reduce the opening angle. An already closed window can be opened manually at elevated wind speed only up to a predetermined angle. On the one hand, this prevents the entry of too much warm or cold air or damage from storm winds.

A central or for each window individual automatic with appropriate sensors, ensures that the user or a subordinate automatic the blinds or windows can only adjust in a restricted area, which prevents damage, too much light, glare or heat loss (with the window open) ,
