DE3238188A1 - One-part mirror blind - Google Patents

Abstract

The blind is intended for inward swinging windows and serves to improve the soundproofing and the security against break-in while at the same time reducing heat losses through the windows at night and increasing daylight penetration. The mirror blind is hinge-mounted on the window base, can be swung outwardly from the vertical into the horizontal and aligned at a desired angle with respect to the sun using a twin-frame system. The blind has the following structure from the inside outwards: mirror, soft insulating panel, stable waterproof panel, which are adhesively bonded to one another and sealed in a light metal frame. The application is suited equally for windows of dwellings or for larger units, such as, for example, greenhouses whose roof structures are not transparent. The mirror blinds combine relatively inexpensive manufacturing cost with advantages which can otherwise only be achieved, in combination, using systems which comprise a blind, insulating glazing and a light trap. Subsequent fitting to many types of windows is possible.

Description

description

The invention relates to the mirror shutter according to the preamble des 1Nnsprucll 1. It is what I do. to an object that is a combination of properties and functions of listed products / technologies abc combined in: a - window shutter, b - insulating glazing, c - light trap system, with the criteria a - increase burglar protection wind and weather protection, sun protection, noise protection b -reduction of heat transfer c -Use of solar energy For the above-mentioned product groups a to c is a variety of forms and techniques from the conventional construction sector known. What they all have in common is their relatively excellent suitability for the more punctual solution Problems.

The invention is based on the object of a system for windows find that the above genanxite criteria are combined with little effort, namely in such a way that when opposing effects occur, these benefits do not may outweigh. This object is achieved in a device according to the claim 1 by the characteristic features in general and when executed according to Subclaims 2-4 specifically solved by the characterizing features.

Special features in the mode of operation of the mirror window shutter and the thus achievable advantages: a / If the window faces east, south or west is aligned and at the same time is little shaded, is when opened des S. with an average high additional light output through the window to count through. It increases as the 5th at a favorable angle to the Sun can be kept. In the colder season this leads to heat gain, the one Offsets part of the additional heat loss caused by the removal of the insulating layer when opening occurs, or even exceeds it.

Another effect, namely the brightening of the ceiling, can be used for special Of interest to greenhouse operations. In apartments this effect can occur if the The upper part of the room has enough reflectivity to enhance wellbeing the residents contribute.

b / insulating glazing has a particularly energy-saving effect at night, if the temperature gradient between room temperature and outside temperature increases. Accordingly, the S. has its greatest benefit in thermal insulation at times where usually nothing stands in the way of darkening the room. Also the need noise protection usually increases at bedtime.

A desired orientation about the lighting conditions outside the home can over a transparent part of the surface when the mirror shutter is closed of the S. can be achieved. In addition, you can see through when it is open down the S. possible.

c / i? ltr long rows of windows can be the S. in very large units built and provided with powered swivel devices. An automated one Adjustability of the mirror angle with the help of photocell-controlled drive systems could be because of the savings in heating and artificial lighting lead to the development of new types of greenhouses.

d / The mirror shutter with double frame system optimizes the possible Incidence of light considerably. The outer frame can be found in the closed state be what, with the appropriate execution, the opening of the S. also in a vertical position Position allows.

e / The mirror shutter can be retrofitted to many window types be cultivated.

An embodiment of the invention is shown in the drawing. It is a mirror shutter with a double frame system for subsequent Attachment to windows, executed with articulated cables with locking screws and window handles.
