6 Claims. (Cl. 160-107) The present invention relates to a window and more particularly to a window of the type provided with a blind between sealed or semisealed pair of glass or insulating glass, which is moved from the outside thereof.

In the past, generally the object of a blind was attained by providing a blind along the window glass, but recently this object has been attained by providing a blind between a double glazed window or a twin glass window.

The blind of some of the windows provided with a blind between two glasses of the kind of the aforementioned twin glass window was moved from the outside, but the seal of the inner portion and the outer portion of a double glazed window was not complete mechanically and no sufficient satisfaction was obtained.

Accordingly, the fundamental object of this invention is to provide a double glazed glass window which can be sealed or sealed through an atmospheric pressure valve completely and which includes a blind which can be moved from the outside.

Further object of this invention is to provide a pair of spaced glass panes and a sealed or semisealed insulating glass including a blind to be operated by a magnetic force from the outside.

Another object of the present invention is to provide a cartridge by which a blind within said insulating glass can be replaced simply.

These and other objects of the invention will be more clearly understood from the following description taken in conjunction with the accompanying drawings.

In the drawings:

FIG. 1 is a perspective view partially cut away to show the inner structure of the window in accordance with the present invention.

FIG. 2 is a sectional view showing the structure of the window frame as shown in FIG. 1.

FIG. 3 is a sectional view of a magnetic device for operating a blind in accordance with the present inven tion.

FIG. 4 is a sectional view showing one embodiment of the magnet means as shown in FIG. 3.

FIG. 5 is a sectional view showing one modification of the magnet means as shown in FIG. 3.

FIG. 6 is a figure similar to FIG. 2 and shows a sec-- tional view showing another embodiment of a blind operating means.

FIG. 7 is a regular elevation view showing a means of adjusting freely a space between magnets mounted on both edges of a blind FIG. 8 is a cross section view of a cartridge by which a folded blind can be removed simply from an insulating glass or a sealed glass window.

FIG. 9 is a sectional view of the cartridge portion showing the status in which a reel type blind is applied a window in accordance with the present invention.

FIG. 10 is a cross sectional view and FIG. 11 is a View partly in cross section illustrating examples of a conventional regulating valve and electric motor.

Referring to FIG. 1, glasses 11 and 12 are affixed by a suitable adhesive onto interval frame 13 made of a non magnetic metal like aluminum or a resin material and mounted onto window frame 10. The space enveloped by said frame 13 and said glasses 11 and 12 is sealed completely from the outside portion by the location of said sealed glass window. For example, in case it is used for a window of an aircraft, the pressure within the aforementioned space can be changed by means of an atmospheric regulating port. In order to mount completely an insulating glass thus constituted onto a window frame, frame 14 is installed. In order to mount said frame 14 onto said frame 10, it is preferable that said mounting is made by a method which allows removal of said frame 14 for repair. Within said insulating glasses, a blind of a folding or reel type or of a type having several slats, made of a quality of material suitable for :the purpose of use is inserted. In FIG. 1, blind 15 of a folding type is shown. Said blind is provided with reinforcement member 16 at one end, the other end being fixed onto said interval frame 13, and, as occasion demands, it has a size which can cover the whole surface of the glasses. At both ends of said reinforcement member 16 is mounted magnet means 17 which correspondingly operates with a magnet means at the outside portion to be described hereunder. Said magnets are usually used in plural number. (The embodiment shown in the figure has three magnets.) The polarity of these magnets mutually face in the opposite direction, and their poles correspondingly face mutually against those of the magnets at the outside facing through frame 13. That is, in magnet means 17 in FIG. 3', pole N of magnet 18 faces in the direction of said frame 13 and pole S attaches to high permeability member 25. Magnet 19 below thereof faces in the opposite direction and magnet 20 faces in the same direction with magnet 18. In FIG. 4, the poles of magnets 18, 19 and 20 are arranged in the order of NS, SN and NS from up to downwards through high permeability member 27, and the magnetic poles N.S.N.S. appear in the direction of frame 13. In the same way, in magnetic means 24- in FIG. 3, pole S of magnet 21 faces in the direction of frame 13, and pole N attaches to high permeability member 26. Magnet 22 below thereof faces in the opposite direction, and magnets 23 and 21 face in the same direction. Also, in FIG. 4, the poles of magnets 21, 22 and 23 are arranged in the order of SN, NS and SN from up to downwards through said high permeability member 28, and magnetic poles appear as S.N.S.N. in the direction of said frame 13. Accordingly, when each magnet is in a normal position, each pole attracts mutually, but, if the outside magnet means 24 begins to move upwards or downwards, the inner magnet means 17 moves in a followup manner by an attractive force. In case said movement is delayed a little and if we explain in connection with. magnets 19 and 22, now assuming that magnet 24 is moved upwards, if magnets 17 and 24 lip off, magnet 19 will approach magnet 23 of the same pole and magnet 22 will approach magnet 18 of the same pole. Accordingly, they will mutually repulse, and magnet 22 will push up magnet 18 and magnet 23 will push up magnet '19, and they-will move so that they will be separated a little from frame 13. As a result thereof, magnet means 17 decreases a frictional force against frame 13 and makes a, followup movement against magnet means 24 easy. Though it is not shown in the figures, even in a device which is planned to decrease the friction between magnet means. 17 and frame 13 through a pulley, the same effects including the friction of the pulley can be attained.

As shown in FIG. 5 as one modification of the aforementioned magnet means, by using a material of a cilium like mohair on the abrasion face of magnets within said insulating glass, a starting abrasion force between each magnet and the frame 13 is decreased, a followup moving operation of magnet means 17 is made smooth, an inching motion is prevented and tear and wear between the two parts is prevented.

The method of moving magnet means 24 mounted on the outside of frame 13 corresponding to each magnet means 17 mounted at the both ends of reinforcement member 16 is performed by a wiring as shown in the embodiment in the figure by rotating handle 29, but it is possible to perform said movement by gearing, and it is also possible to replace said handle by an electric motor. However, since these matters belong to the conventional prior art and belong to the field outside of the scope of this invention we omit to mention them in detail.

Another modification of the method of moving said magnet means 24 is shown in FIG. 6. In this method, member 30 is provided which extends along the outside face of either one of the glasses between two magnet means 24 located at the both sides of said frame 13. By moving manually said member 30 up and down, the blind within the insulating glasses is made to move up and down by means of a magnet force.

In order that magnet means 17 located at the both ends of reinforcement member 16 moves along the inner face of the frame 13 and to follow-up the shape of the frame, as shown in FIG. 7, means 3-1 is mounted among member 16 and magnet means ,17. Member 16 is provided with Member 16 is provided with an.

magnet means 17. elongated slat for adjusting fixing means 31 to member 16 by means of a bolt and nut.

As shown by a cross section view in FIG. 8 as one embodiment of the present invention, member 33 onto which cartridge 34 for holding a blind is mounted is fixed by a thermosetting or a nonreversible setting adhesive onto the inner face of one end portion of glasses 11 and 112. Also, said cartridge and said member 33 are fixed by a thermosoftening adhesive. Accordingly, in case the blind is replaced, it is easy to remove said cartridge by heating said member 33.

In case a blind of a reel type is applied in accordance with the present invention, it is performed by mounting cartridge 35 provided with winding pillar 36 onto which the blind 15 is wound as shown by a cross section in FIG. 9 by the similar method as shown in the embodiment in FIG. 8. If blind 15 is held by said winding pillar 36, it is preferable to provide a proper spring means which rotates in the winding direction.

Since the inner portion of the insulating glasses in accordance with the present invention is sealed completely from the outside portion or semisealed by an atmospheric pressure regulating valve, a blind is free from dust or other bad effects; it is especially possible to fill an inert gaseous body such as dried air or carbonic acid gas into the inner portion thereof and thereby the effect of intercepting a heat conduction is heightened and the aging of the blind can be prevented. Further, if the glass used is of a type intercepting ultraviolet rays and infrared rays, the effect thereof is further larger.

As shown in FIGS. and 11,

41 is a regulating valve connected to a suitable source;

42, a piping connecting said valve to the inner space of said window;

- 51, a bevel gear fixed to the shaft;

52, a bevel gear engaging with gear 51 and fixed to the shaft 53 of an electric motor 54 located in suitable position, for example on the window frame;

55, a switch for reversibly actuating the motor 54;

56, an electric source, and i 57 a casing.

As mentioned above, we have mentioned one embodiment of this invention, but this invention is not limited to the above description butto the claims mentioned below. It is understood, however, that the people engaged in the same business can readily perform various variations but of course these variations belong to the scope of this patent claim.

What is claimed is:

-1. In a double glazed window comprising two glass sheets or plates and a frame sealably supporting them on the peripheral sides thereof in parallel in spaced relationship with each other, a displaceable blind located in the space between said two sheets or glass plates movable between a first position completely closing the blind and a second position completely opening the blind, said window characterized by the fact that said blind is provided .with magnet means at both ends of one edge thereof transverse to the direction of movement of said blind, said magnet means comprising a plurality of magnets which are arranged in series with their polarity alternately reversed and in close spaced apart relationship from each other and being adapted to be moved along within the opposed sides of said frame, second magnet means being provided on each of said opposed sides of said frame in opposed relation relative to each of said first. magnet 3 means externally of said inner space and being movable along said sides by means of wire and the like which effects the movement of said second magnet means along said sides, said second magnet means comprising magnets of the same number as those of said first magnet means arranged in series with their polarity mutually opposite to each of the magnets of said first magnet means positioned in opposed relation to said second magnet means, thereby said first magnet means being entrained by the movement of said second magnet means due to the magnetic attraction therebetween, frictional resistance between both said first and second magnet means and said sides of said frame being reduced due to the shifted position of said first magnet means relative to said second magnet means oppositely arranged thereto during said entrained movement of said first magnet means because of said alternately arranged polarity of magnets in both said first and second magnet means, hence, said foldable blind being moved to any position between completely closed and completely opened without leaving any portion of said blind within the transparent area of said window, from which said blind is removed.

2. A device as in claim 1 wherein the means for securing the cartridge to the panes comprises a therma-softening adhesive.

3. A device as in claim 1 wherein the blind comprises a plurality of accordion pleats and means securing the lowermost pleat to the cartridge.

4. A device as in claim 1 wherein the blind comprises a sheet and a pillar rotatably mounted in the cartridge,

said sheet being wound around the pillar.
