Curtain/Shutter Which Flips and Changes to Several Options

Abstract

Curtain/screen/shutter which flips and changes to several options

Description

1. A Curtain or, shutter (the sections below apply to the curtain, except for the current section that also applies to the shutter) that rises from the bottom of the window or door upwards so that people shouldn't be able to look into the room from the outside (such as a ground floor window or a regular window which extends from tire ground up, etc.), but allowing air to enter from above, and also descends from above downwards when you want shade the sun from above while leaving it open from below.

2. The curtain is to be wind resistant and stay stable and straight even when the window is open and wind enters.

3. When completely closed creates a hermetically sealed closure to the window, complete separation from outside and complete darkness inside the room.

4. When closed the window becomes a framed picture. (Such that it is not noticeable that it is a closed window with a curtain)

5. When fully open, it looks like a window frame with no curtain at all.

A sheet or shutter (henceforth called sheet) (item 1), which will fit into the frame (item 12) which is the size of the window. From the four corners of the sheet there will be strings (item 2) slightly longer than the length of the window.

At the edge of the rods (item 8) there will be gears (item 4).

The frame (item 12) which is the size of the window will mount on to the window frame.

The rods (item 8) which are the size of the frame's (item 12) width, will be in an indent on the other frame (item 9), on the upper and lower portions of this frame.

The rods (item 8) will be placed into the top and bottom indents in the frame (item 9), while the strings (item 2) are rolled around and stretched on them.

Over gears (item 4) a chain (item 7) will be passed. (in order to prevent the strings and the curtain from loosening). (And on the shutter the connection on the lower part and the stretching of the strings and the chain create a condition of easy rotation without obstruction whenever it is being rolled down).

On the edges of the frame (item 12)(from the right and left) on the inner part there will be grooves (item 10) that the curtain sheet (item 1) will be inserted slightly. (For hermetically sealed closing, the stability of the cloth and the perfect appearance of the picture).

In the frame (item 10) on the top and the bottom, there will be slits for the curtain to exit from the top and bottom.

The rods (item 3) will be wide at the sides (item 5) and will protrude at to the frame's height precisely (with the groove in the frame (item 11)) so they should be able to rotate. Or an option to rotate it from the edges of the frame. (Using a protrusion from that rod (item 6). Also by passing a string from the top to the bottom at the edges of the rods).

On the cloth (item 1) it will be possible to print any picture (or to stick any picture made of cloth or any suitable material).

It will be possible to build it in to the window's structure, as the widow itself is built.

It will also be possible to incorporate a spring which will close the curtain by pressing a button (by releasing a gear which will be connected to a spring or things like that) additionally it will be possible to operate mechanically, and it will combine both mechanical and manual options.

Even though it mentions in the above description a sheet or a cloth curtain, it is also possible to use any material which can be used as a partition or shade.

And even though it mentions in the above description a top part and a bottom part, it can also be placed diagonally, tilted, or any orientation.

And even though it mentions in the above description a window or door space, the description is used as an example for the idea.

And even though we brought one example for building the product, there are other methods and the above is an example for the idea.

• • 1. A curtain/shutter
  • 2. Strings/belts, which connect the curtain/shutter (henceforth curtain) to shafts which the curtain rotates on them as it opens.
  • 3. Shafts which the curtain rolls up on as it opens.
  • 4. A gear which on it a chain belt which connects between the upper wheel to the lower one and creates a uniform motion of the upper and lower shafts and makes it impossible for the curtain and the strings to loosen or spin about itself.
  • 5. Widening of the rod at its edge to leave the curtain frame for holding in order to open and close the curtain (if option 6 is not relevant).
  • 6. The rod protrusion from the frame to the side (where possible) in order to rotate the rod for opening or closing the curtain.
  • 7. The chain's belt which connects the upper to the lower gears to ensure that the rods spin together and the curtain should open and close without becoming loose or spin around the rod.
  • 8. The rod should be narrow in a manner that the string/belt will rotate on it.
  • 9. The opening for the rod's edge to create the ability to open and close the curtain by rotating the end of the rod.
  • 10. Openings for inserting the curtain at the edges to create additional balance for the curtain, and to make a greater view of the picture.
  • 11. The rod exiting for rolling up the curtain and opening and closing it (whenever it is impossible to do from the sides).
  • 12. A frame for the curtain which creates a picture look when closed, and a window view when open, without a curtain look at all (this can be built in the window frame itself during the window production).

Claims

1. A sheet for a window or door space. A: When the sheet rises by using a spreading spool from the bottom of the window upwards to prevent looking in to the room from outside, but air can enter from above. B: Such that the sheet descends also from the top downwards using the spreading spool whenever a shade is desired to shade from the sun which is coming in from the top and to leave it open from the bottom.

2. Regarding the sheet written in claim 1, whenever it is closed is will be wind resistant, and will remain stable and straight also when the window is open and air is entering: A: Such that the spreading sheet includes string which stabilize the said sheet by being tied from the sheet to the rod or wheels etc. On the other side of the frame. And chain belts or stretched strings go over the rods or on gears which are on the rods, and connect between the upper and lower rods which cause the sheet to become tight and won't loosen. This causes the curtain to be firm in any situation even if it wouldn't be stable for other reasons, without the wind factor, such as it being installed diagonally, slanted or any orientation. AndB: The said sheet includes a frame which has grooves for the sheet to exit, the frame holds and stabilizes the sheet and adds strength to the stable sheet using the said strings.

3. The said sheet from claim 2, when it opens or closes, it will roll up in a uniform fashion from both sides, without the ability for entanglement and movement from its wanted place. A: Such that the said sheet includes a sheet which is held from its four corners on the spooling sections which are attached to the frame from above and below, using the strings and chain belts, and is as said in claim 2 subsection A.

4. The sheet mentioned in claim 2, whenever the sheet is closed entirely, it creates a hermetic seal to the window, an absolute separation from outside, and complete darkness in the room: A: Such that the said sheet includes a frame which has grooves for the sheet to exit, which in it there are parts affixed to it which rotate that on them the sheet rotates etc. And as specified in claim 2 subsection B, and as the sheet closes the sheet enters into the frame from its four sides.

5. The said sheet in claim 2 it will look like a window frame without any curtain at all: A: Such that the said sheet includes a frame as specified in claim 2 subsection B. And the sheet will roll up into the frame.
