This relates to an opening/closing device for an opening in a building facing the building.

The purpose of this invention is to provide an excellent crime prevention effect by closing the real voice, and also to eliminate the need for thick curtains, allowing for free lighting, blocking, ventilation, and wind blocking, and the use of louvers. To provide an opening/closing device for an opening in a building, which can be opened/closed from the indoor side with one hand.

The present invention will be explained in detail below using examples.

A sash frame 6 is attached to the outdoor side of the opening 1 of the building, and a glass door 2 is attached to this sash frame 6 so that it can be opened and closed in a sliding manner.

A lintel 7 and a sill 8 are provided above and below on the indoor side of the opening 1 of the building, and the lintel 7 and sill 8 are twice or more than twice as long as the horizontal length of the opening 1. , both ends of the lintel 7 and the threshold 8 serve as storage rail portions 9, which protrude along the wall to the left and right of the opening 1, respectively;
The length of each storage rail section 9 is 172 cm of the horizontal length of the opening 1.
or more.

Two dead weights 5 are slidably arranged between the lintel 7 and the sill 8, and when the left and right dead weights 5 are stored in the storage rail section 9, the indoor side of the opening 1 is opened, and the dead weight 5 from the storage rail portion 9, the indoor side of the opening 1 is closed by its own weight 5.

The dead weight 5 is constructed by rotatably mounting a large number of louvers A within a frame 5a.

Here, in order to make the louver A freely rotatable, it is preferable to use the following mechanism, for example.

That is, the louvers A are formed in a Z-shaped cross section, and are arranged in a plurality of rows vertically, with both ends pivoted to vertical frames 15 forming the frame 5a.

In this case, the rotating shaft 17 of the holder 16 that holds one side end of the louver A is supported in a shaft hole 18 provided on the inner surface of the vertical stile 15, and the eccentric shaft 19 eccentric to the rotating shaft 17 is vertically supported. A hanging wheel 22 that stops in the cut groove 33 of a vertically movable connecting frame 20 housed in the stile 15 and rotates with the operation lever 21 is arranged on the vertical stile 15, and engages with this hanging wheel 22 to rotate the hanging wheel 22. The connecting frame 7 is provided with locking teeth 23 for moving the connecting frame 20 up and down.

The operating lever 21 is rotatably mounted on a plate 24 with rooks attached, fixing pieces 26 on both sides of the lower end of the plate 24 are fixed on both sides of the inside of the vertical stile 15, and rooks are attached on both sides of the upper part of the plate 24. The connecting frame 20 is held in place by the extending L-shaped piece 25, and when the connecting frame 20 and the rook are attached to the vertical stile 15, the operation lever 21 is protruded from the round hole 27 of the cover 32 that hides the plate 24. The operating lever 21 can be rotated from inside the room.

Further, as shown in FIG. 7, the hanging wheel 22 is formed by protruding spiral guide pieces 29 from the back surface of a disc 28 that has a mark on a part of its outer periphery. The spacing S is made the same as the spacing S of the locking teeth 23, and the locking teeth 23 are meshed with the spiral grooves 30 formed between the spiral guide pieces 27, as shown by the arrows X in FIGS. 6 and 8. By rotating the hanging wheel 22 in the direction, the locking teeth 23 are sequentially moved from the lower locking tooth 23 to the spiral groove 3 from the entrance 31 at the outermost end of the rook 22.
0, grips the locking tooth 23 one step higher with each rotation, advances the locking tooth 23 from the inner circumference to the outer circumference along the spiral groove 30, and as a result lowers the connecting frame 20. Conversely, when the hanging wheel 22 is turned in the direction of the arrow, the connecting frame 20 rises.

Incidentally, when the connecting frame 20 moves up and down, the eccentric shaft 19 moves up and down, so the louver A rotates around the rotating shaft 17.

By rotating the louver A in this way, the ends of the louver A can be brought into contact with each other and sealed, or the louver A can be sealed.
It creates an arbitrary gap between them.

Here, the louver A is made of metal, and the interior surface 1 is covered with the same material as the interior of the room or a material that is in harmony with it.

That is, the outdoor surface is covered with a metal plate, and a cloth or the like is placed on the metal plate to form the indoor surface.

Of course, the interior material in this case is not limited to cloth, and may also be a wooden decorative board or the like.

However, when the dead weight 5 is open, the opening 1 is opened and closed only by the glass door 2, but when the dead weight 5 is closed, the dead weight 5 is opened and closed.
will play a role in crime prevention.

Even in this case, light can be let in by rotating the louvers A to form a gap between them, and the amount of light let in can be adjusted by adjusting the rotation angle of the louvers A.

Also, at this time, if the glass door 2 is left open in advance, ventilation can be obtained.

Further, by rotating the louver A so that the end portions of the louver A are brought into contact with each other, the dead weight 5 is completely sealed, improving the fire prevention performance, and at the same time, the light is completely blocked.

In this way, with the present invention, by closing the dead weight 5, the indoor side of the opening 1 can be closed without the need for a thick curtain, and since the louvers are attached to the frame, it is possible to close the indoor side of the opening 1, which is very difficult to do with conventional curtains. It has an unexpected crime prevention effect, and even when closed, it can freely let in light, block light, and block ventilation.

Further, in the above embodiment, both ends of the lintel 7 and the threshold 8 are used as storage rail portions 9, and the storage rail portions 9 at both ends are made to protrude along the wall to the left and right of the opening 1, so that the self-weight 5
Although it is designed to be stored on the left and right sides, only one end of the lintel 7 and the threshold 8 may be used as a storage rail portion, and the dead weight 5 may be stored only on one side.

Further, in the figure, the wall is a double wall so that the stored state of the dead weight 5 cannot be seen from inside the room due to the double wall indoor wall 11.

Of course, the indoor wall 11 may not be provided.

In the figure, 10 is a screen door, and 12 is an outdoor wall.

Further, 13 is a flooring material.

In the figure, 14 is a contact material whose own weight is 5. As described above, in this invention, a glass door is placed on the outdoor side of the opening, and the indoor side of the opening can be opened and closed using its own weight as a sliding door with a large number of louvers rotatably attached within the frame. In other words, since the glass door is installed on the outdoor side and the louver is attached to the sliding door so that it can rotate freely, the glass door can be protected from the inside by blocking the dead weight, and children etc. This has the advantage of preventing people from accidentally breaking the glass door and getting injured by the glass.

Furthermore, since the louver is equipped with a rotatable sliding door on the indoor side, the louver can be opened and closed from the indoor side, allowing you to change and adjust the amount of light and air intake from the indoor side. The louver can be conveniently opened and closed when the outdoor glass door is closed, such as when there is strong wind and rain.

Furthermore, although the rotation of the louver can be performed from the indoor side by rotating the control lever facing the indoor side, the operation configuration is such that the rotation of the spiral guide piece is performed by rotating the spiral guide piece. The connecting frame is moved in a direction approximately perpendicular to the length direction of the louver by rotating the guide piece through the locking teeth engaged with the louver, and as this movement is performed, the connecting frame is locked in the moving direction. The eccentric shaft moves like a crankshaft, and the movement of this eccentric shaft like a crankshaft rotates the rotation shaft of the louver, changing the amount of opening of the louver. It has the advantage that it can be operated with one hand and improves operability compared to opening/closing means for lifting and lowering, which operates in the form of a rope.
