DE3020943A1 - Insulating glazing fitted as additional sliding panes - or flexible unrolled sheet lowered as blind across window - Google Patents

Abstract

Thermally insulating secondary or subsidiary glazing for a window consists of loose panes or sheets, which can be slid together and stacked, fitted to the outsideor inside of the window assembly. Individual sheets of an appropriate clearly translucent or tinted material are slid upwards from the bottom, or from the top or from either side across the window. In a preferred embodiment, a plexiglass or other transparent material is mound on a roll like a blind and is lowered across the window pane. In a variant (illustrated but not claimed) a number of panes having hooked-over tops and bottoms are arranged so that as each is pulled out its bottom hook engages the top hook on the next pane and so on. Thus a multiple-glazed pane in obtd. in normal use. This arrangement is intended to provide extremely simple, inexpensive insulating glazing either for subsequent addition to an existing window or for the initial installation, which has a very high thermal efficiency.

Description

Title: T h e r m 0 - Z w e 1 t f e n 5 t e r

Application: The invention relates to a window construction which is installed outside in front of or inside behind an existing window.

Purpose: Windows have a high heat loss. To mitigate - improved Thermal insulation - the second thermal window should be used.

State of the art: To reduce heat loss from a window, there are the following constructions: 1. The "box window" Two glazed wings are attached to a frame in a box shape with an air gap of 6 - 8 cm.

2. The "composite window" Two glazed wings are connected to each other Closure firmly connected and attached to a frame like a single wing.

3. The insulating glass window "Two panes of glass with an air gap of 6 - 8 mm are welded together airtight and built into a wing. Also three Glass panes are possible.

Criticism of the state of the art: The thermal insulation value o. A. construction is low. An improvement through the installation of further glazed sashes is constructive difficult and economically unreasonable.

3-pane insulating glazing # also requires heavy window constructions. In the summer months, the "increased" insulation value of the windows is not desirable. Exposure to sunlight brings a considerable gain in heat. The fixed window systems can, however only change with effort.

Task: The invention is based on the object with simple constructive Means for the cold season or at night another heat-insulating glazing to make available and this in solar radiation to achieve a heat gain to remove again. This "second window" should be simple and unchanged provided by facades.

Solution: According to the invention, this object is achieved in that the Slats made of glass, plexiglass or optional material, such as a roller shutter is attached from top to bottom or from the side in to the outside of the window. The slats are pulled apart or together by means of a belt pull, crank or motor.

Another embodiment of the invention: the second window can be inside simply attached to the wall via the existing window. Cover curtains the side or top lamellar pocket. Outside is the l, amellen pocket in the area to fasten the outer roller shutter cladding. The cladding of the roller shutter can z. B.

removed and replaced by the lamellar pocket.

The view is somewhat obstructed by the "joints" of the slats. It is therefore used especially on windows in north, east and east positions or in less important rooms or

with "terminated utilization times".

Achievable advantages: No changes to existing window systems and building views. To be attached inside and outside.

Use for "targeted" heat saving on any window of a building. The largely air-closing slats create an insulating effect Air box created in front of or behind the existing window system.

Heat losses through "leaky windows" are made through the second window canceled, Protection of existing window systems from moisture, etc.

Increase in the first service life of existing windows.

Considerable improvement in noise protection (street noise).

Additional burglary protection.

If the slats are slightly colored, also sun protection.

Description of an embodiment 5-example: Sin building has through window high heat losses to the north, east or west. A slight nuisance the view through the "slat joints" can be accepted. On window exposure the rooms cannot be dispensed with. From the outside, the "thermal second window" attached. A hole of 8 mm for the crank or motor supply line is the only one Breakthrough inwards.

If the "thermo-second window" is installed vertically inside, they disturb vertical joints of the slats not if there is a curtain system inside.

Claims (1)

Claim 1, preamble 1: A heat-insulating second window To mount loose, collapsible slats on the outside or inside of window systems. Characteristic part 1: This is characterized by the fact that individual lamellae Made of a choice of material, transparent or colored for sun protection as a second thermal window to increase the thermal insulation available or newly planned window systems in buildings attached inside or outside. The slats can go from top to bottom, from bottom to top and to the side be pushed together from right to left or from left to right. Patent claim 2 preamble of sub-claim 2: Transparent Slats made of plexiglass or other transparent material became a roll Rolled up and let down during the day serve as a second window 1. Identifying part 2: characterized in that made of transparent, Optionally coherent lamellas rolled up and down on a roller will.
