The invention relates to a device for controlling curtains, placed in a closed glass chamber.

It is well known that residential buildings lose a lot of heat through Windows and glazed doors, and that this dispersion can be significantly reduced by using double glazing with sealed insulated chamber between the panes.

The presence of curtains, including blinds or pleated blinds, inside a closed glass chamber, leads to difficulties because of the need to control them from the outside, without compromising the hermetic isolation.

Were developed and applied to various control systems, connecting the inner and outer kinematic mechanisms forces the magnetic field, the current through one of the Windows.

Such devices are, however, rather complicated and expensive.

The main difficulties are the need to keep moving parallelism of various parts of the curtain relative to each other. An internal electric motor significantly increases costs because of the need in geared mechanisms.

Manage outside solely by mechanical means such as cords, creates problems associated with the tendency to slippage between the inner and outer mechanisms, the United forces of the magnetic field.

By mentioning the th invention eliminates these disadvantages, providing a smooth inner and outer curtain's movement through the magnetic connections that are using the ingenious solution that consists of a simple and inexpensive means which will be described later.

Object of the invention is the creation of a system of control curtains inside a closed glass chamber containing two window panes, the frame formed by four sections - one top, one bottom, and two side sections, all of which are held together by four parts, one on each corner.

One fixed end curtains inserted in the stationary frame, which is here called the upper box, attached to the upper frame, while the other end of the curtains attached to the rolling frame, which moves the device, the current through one of the window glass and is controlled by a device intended for the direction of movement of the specified rolling boxes parallel to itself during the operations of opening and closing of curtains depending on how may be the spatial position of the glass chamber.

Device for moving a movable box contains two tools that operate in tandem to create a magnetic attraction.

First means attached to the rolling frame, while the second consists of free pens.

Apasov is in the pen tool, attached to the rolling box and moving it by hand, you can optionally open and close the curtain.

Means, attached to the rolling box consists of a small box in the form of a parallelepiped, which is located inside the housing containing one or more parallel magnets, which are placed in the longitudinal direction between the two groups freely rotating rollers with longitudinal axes.

The several rollers protrude from the geometric plane passing through the outer surface of these permanent magnets, and from the front surface of the moving boxes, so that one can more easily glide over the glass.

Preferably each group has two rollers with a slightly curved surface for a brief contact with the glass.

Handle, forming a second tool, has essentially the shape of a parallelepiped and has a capacity of one or more permanent magnets placed longitudinally adjacent to each other, with their poles opposite poles of permanent magnets in the first means, and these magnets are provided with a thin coating of material such as Teflon, Velcro, etc. so that they can easily glide over the glass.

On the basis of the first means and the handle imposed a thin metal plate to hold the magnets.

A guiding device which consists of a pair of interacting cords.

The first cord is attached near the first end of the stationary boxes, stretches, even through the curtain, before rolling boxes, passes under the first inner transverse roller is rotated near the first end of the specified rolling boxes, extends to the second end of the latter passes over the second lateral end of the roller and is then fastened to the second end of the duct, which is called here the bottom of the box, installed on the lower section of the frame.

The second cord is attached near the second end of the stationary boxes, stretches, even through the curtain, before rolling boxes, passes under the third internal transverse roller is rotated near to the second end of the movable duct, extends to the first end of the specified rolling boxes, runs around the fourth lateral end of the roller and is attached to the first end of the lower boxes.

Thus, the movement of the rolling box for opening or closing the curtains at the same time causes a change in the length of the first segments of the two cords that connect the specified movable box with a fixed frame, and the change of length, equal or different, second segments of these cords connecting the specified movable box with a fixed box.

Thus, the movable frame is moved parallel to itself.

When the wide, the curtains to the stationary duct attach the second pair of cords. Segments that connect the specified second pair of cords with a movable box, placed in the gap between the line segments of the first pair of cords and sent the other intermediate rollers.

Segments that connect the specified second pair of cords with the lower stationary frame, sent by the same rollers, placed on the ends of the specified rolling boxes, which serve as guides for the first pair of cords.

The ends of the cords are attached one to each end of the lower stationary boxes by means of elastic parts, which automatically eliminate changes in length due to thermal and mechanical loads.

The elastic parts are mostly cylindrical springs, located on the heads attached to the ends of the bottom of the box and provided with grooves into which may be missing cords.

One end of each cord is passed within the above-mentioned springs and attached to their end.

Four parts of the frame are tubular, the tube has a constant cross-section.

The lateral surface of these pipes, facing toward the inside of the frame is flat.

At each end of each corner details are tie with an elastic wave, which is pressed inside the ends of the tubular parts.

The cross-sectional shape of the upper and lower stationary boxes pre the given rectangular U, with the flat side facing the tubular sections of the frame.

Edge straight sides of the "U" bent like hooks being turned in opposite directions, while the two longitudinal edges of the flat sides of the tubular components of the frame has hooks facing each other.

The size and shape of these hooks are what make it possible to set a fixed upper and lower boxes on the tubular section of the frame, pressing the hooks on the boxes in the hooks on these tubular sections.

Form a constant cross-section rolling boxes essentially corresponds to the rectangular U, has a transverse aperture, forming an internal groove, and a channel in the form of a rectangular U that is open in the direction of the curtains.

Shading light shields installed on facing the inside edges of the flat sides of the side sections of the frame.

Shading light shields set on the edge of the corresponding outer side of the closed glass chamber, the flat side of the stationary boxes.

The rollers moving inside the box, around which skipped guides cords, preferably rely on internal head placed inside a channel that is open toward the upper stationary boxes.

The end rollers are supported by the heads attached to the ends of the specified rolling boxes reeds like the outdoor channel, and in the inner channel.

The cords are missing inside the grooves made for them in all the above mentioned heads.

In one implementation options of the curtain is corrugated. In this case, the upper stationary frame provided on its flat back surface, facing the curtain, a pair of ribs forming a pair of opposing channels.

Similarly, at the ends of the open channel mobile trunking is a pair of edges forming a pair of opposing channels.

Thus the two ends of the shirred curtains can be inserted into these a pair of opposing channels in the upper stationary frame and the movable frame.

The curtain may be a curtain roller, blinds or shutters of any other kind.

The invention offers obvious advantages.

Thanks to the coordination of the pulling device and the sending device, the curtain can be opened or closed through a single pane of glass sealed glass chamber that is carried out by means which are inexpensive, reliable and easy to use.

A guiding device solves the universal problem of moving mechanical device, parallel to itself.

Because the movement is using cords, these cords can pull at a certain distance, so that the sizes of the float, in this case, the curtains are not limited to.

The cords do not require direct guides and provide an effective replacement for existing mechanical systems in the form of a parallelogram, at the same time which is difficult and cumbersome.

Described parallel movement makes it possible to use extremely simple and reliable haul-off, limited only by its use essentially anywhere in the rolling boxes, attached to the curtain, avoiding all of the difficulties that are currently used devices for pulling and directions.

By means of a magnetic connection manual exposure can be applied directly to the curtain, preserving the integrity of the closed glass chamber.

The described invention provides an inexpensive, simple and reliable closed glass chamber, which would certainly gain popularity among users.

Features and task descriptions will become even clearer from the following examples of implementation, illustrated schematically depicted figures.
