[0001] The invention relates to the field of construction, namely to the glass window and
door equipped with the device protecting from the light.
[0002] There is known the method of tinting of the hermetic double-glass pane, which provides
filling of the double-glass pane with a colored liquid by means of hydrocylinders,
which are not of a small size and are located outside the frame and their operation
requests some physical effort /1/.
[0003] The presented invention provides the method of rapid tinting of the double-glass
pane placed in the door or window leaf and rapid recovery of its transparency without
using any additional facilities from the existing external space. The presented device
does not contain electronic instruments and accordingly does not require the electric
power source.
[0004] The technical result of the invention is a simplification and increasing of the rate
of the transparency changing of the double-glass pane placed in the door or window
leaf without worsening of transparency quality.
[0005] The technical result is reached by reservoir which is constructed in the lower horizontal
element of the double-glass pane frame inserted in the window or door leaf, and wherein
is introduced the double-glass pane tinting substance. The capacity of the said reservoir
is equal or more than the capacity of the space existing between the glasses. On purpose
to put the window or door leaf in desire position the reservoir is turning over by
180 ° around the central horizontal axis in vertical plane towards the immovable external
frame.
[0006] Tinting of the double-glass pane is carried out by any non-transparent substance.
It is possible to use liquid or solid homogeneous powdery (sandy) mass consisting
of sphere form crumbs.
[0007] The internal capacity of the double-glass pane is filled with non-transparent substance
or emptied due to the earth gravity.
[0008] Non-transparent substance moves in the united space created by the reservoir arranged
in the double-glass pane and its frame's one of the horizontal elements. The said
space is formed as a vessel having two equal capacity containers hermetically isolated
from the environment, and connected to each other.
[0009] The Invention is presented in two figures.
On the Figure 1 is shown the window or door leaf with transparent double-glass pane.
On the Figure 2 is shown the window or door leaf with non-transparent double-glass
pane.
[0010] In the frame of window or door
1 there is inserted window or door leaf
2, wherein is inserted the double-glass pane
3, which consists of two glasses distanced from each other by 0,5÷3mm and connected
by three sides uncontinuously. In one of the horizontal elements of the leaf
2 of the frame there is constructed the reservoir
4 which is connected to the space between the glasses by holes
5, filled with tinting substance and except the holes connecting to the double-glass
is duly protected on all sides from leaking of tinting substance which capacity is
equal or more than capacity of the space between the double-glass pane. There are
fixed horizontal axis
6 in the height of the vertical elements of the window or door leaf
2 frame on the midpoints by which this frame is connected to the window's or door's
immovable frame
1 for turning over in vertical plane around of said axes by 180° towards the immovable
frame on purpose to put the window or door leaf in desired position.
[0011] The double-glass pane is used by following:
Initially filled with tinting substance the reservoir 4 is placed in the lower part of the window leaf 2 (Fig.1). At this time the double-glass pane 3 is empty and transparent. After turning over by 180° through the vertical axis of
the window leaf by force of gravity (unit weight) the tinting substance flows down
(pours into) in the double-glass pane and fills it (Fig. 2). In this position the
double-glass pane is filled with tinting substance and is non-transparent.
[0012] It is possible to fix the movable and immovable frames in the desired position towards
each other by using any ordinary mechanical locking devices (are not shown on the
figures).
[0013] The presented using of the double-glass pane is a preferable one compared with its
other known analogues, because of simplicity of its use, needed no additional fittings
and energy application, and in case of necessity the leaf by simple turning becomes
tinted and transparent again. The tinting substance reservoir constructed in the horizontal
element of the leaf is fully protected from three sides, but from the opened forth
side is hermetically connected to the space between the glasses. The tinting substance
is collected in the internal hollow space of the window or door leafs lower horizontal
element, imperceptible from outer glance, by force of gravity when substance flows
out from the double-glass pane connected to it and the double-glass pane becomes transparent
by itself or vice-versa the tinting substance fills the double-glass pane and it becomes
tinted.
1. A window which contains a framed leaf with double-glass pane, a reservoir constructed
in the element of the frame of the double-glass pane and filled with tinting substance,
characterized in that the horizontal axis are fixed in the height of the vertical elements of the window
leaf frame on the midpoints by which the frame is connected to the window's frame,
the window leaf has a possibility to turn over in vertical plane around of said axes
by 180° towards the immovable frame on purpose for movement of tinting substance due
to its own gravity between the reservoir and double-glass pane, therein tinting substance
reservoir is completely placed in one of the horizontal elements of the window leaf's
frame and its capacity is hermetically connected to the internal capacity of the double-glass
pane.
2. A window, according to claim 1, characterized in that the reservoir and the internal capacity of the double-glass pane is hermetically
isolated from environment.
3. A window, according to claim 1, characterized in that the capacity of the reservoir is equal or more than the capacity of the space between
the glasses.
Amended claims in accordance with Rule 137(2) EPC.
