Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an opening provided in a building and its opening/closing mechanism.

Traditionally, windows were provided as openings in buildings to provide ventilation and light. When looking at skylights and multi-panel windows, they are located high up, and there are many proposals for window types and opening/closing mechanisms. For example, skylights, windows on vertical walls near the ridges of multi-buildings in factories, roofs of greenhouses, etc. that can be opened and closed widely are equipped with opening shoji screens. Since the windows open outward from the top or rotate, there is a high risk of them being blown away by strong winds, and large forces are applied to the opening/closing mechanism, often resulting in damage. Another problem is that it is generally difficult to make a large opening in a skylight that opens. Therefore, if you use a sliding shoji style window, it becomes difficult to open and close skylights and other high windows. or,
When increasing the opening width, sliding shoji cannot be opened and closed smoothly with only guide rails on both sides, and especially when it comes to vertical windows, the width cannot be made larger than the vertical dimension. be.

This invention provides a large opening, especially a wide opening, with an extremely wide shoji in the form of a raised/lowered window.
The object of the present invention is to provide an opening/closing mechanism that can move the shoji in parallel.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing the entire invention. This example relates to a skylight.
The roof whose whole is indicated by the code 1 has an upper frame 2, a lower frame 3,
It has a framework in which side frames 4, 4 are assembled on four sides, but when the roof width is large, an intermediate frame is provided on the indoor side to connect the upper frame 2 and the lower frame 3.

As shown in the plan view of the roof frame in Fig. 2, the roof 1 includes parallel cross beams 5,5 connecting the side frames 4,4 parallel to the surface of the roof 1, and diagonal beams connecting the cross beams 5,5. The upper ends of four pillars erected on the ground are rigidly connected to the joints of the horizontal beams 5, 5 and diagonal beams 6, 6 of 6, 6, and as shown in Fig. 1, there is an entrance 8 in the front and walls 9 on the other three sides. is provided. The roof 1 is sloped downward toward the entrance 8 side.

FIG. 3 is a vertical cross-sectional view of the roof portion seen from the front in FIG. 1, perpendicular to the plane, ie, a cross-sectional view taken along the line AA in FIG. The side frames 4, 4 have three guide grooves 4-.
1, 4-2, grooves 4-3 are provided, shoji 11,
12 are movably fitted into the guide grooves 4-1 and 4-2, respectively, and the shoji 13 is fitted into the grooves 4-3, and there is liquid solidification between the upper frame 2 and the side frame 4. Water sealing material has been installed. Although the shoji 11, 12, and 13 are made of a light alloy material in this embodiment, they may be used as a frame in greenhouses, sunrooms, etc., with glass fitted into the inner periphery of the stile through glazing beads.

Figure 4 of the BB sectional view of Figure 1 or C of Figure 1
As shown in FIG. 5 of the -C sectional view, an upward protrusion 11-1 at the top of the shoji 11 and a downward protrusion 12-1 at the bottom of the shoji 12 are inserted, and the upward protrusion at the top of the shoji 12 is inserted. The downward protruding strip 13-1 of the lower part of the shoji 13 is inserted into the strip 12-2. Therefore, the shoji 12 cannot be moved when the shoji 11 is closed.

As shown in FIG. 1, a horizontal rotation axis 1 is perpendicular to the moving direction of the shoji 11 and parallel to the surface of the shoji 11.
4 is supported by a bearing 15 fixed to the shoji 11 so as to be allowed to move in the axial direction. Rotating shaft 14
A drive rope pulley 17 is rotatably supported by bearings 16, 16 fixed to the upper frame 2 in parallel with the drive rope pulley 17 so as not to move in the axial direction. A rectangular drive shaft 18 is fitted and rigidly coupled in the rotational direction, and a sleeve 19 that fits into the bearing 21 is fitted into the drive shaft 18 and the upper frame 2
It is supported via a sleeve 19 by a bearing 21 fixed to the shaft, and a rope pulley 22 is fixed to the shaft end.

Rope wheels 23, 24 are fitted into the rotating shaft 14, and a set screw 25 is screwed into the internal thread carved in the radial direction from the cylindrical outer periphery of the rope wheels 23, 24. The position can be freely adjusted and mounted in the rotation direction of 14.

As shown in FIGS. 1 and 4, the rope car 23
The wire rope 26 is wound around the rope wheel 23 perpendicularly to the rope wheel 23 by one or more turns to prevent it from slipping, and one end is fixed to the upper frame 2 so that the wire rope 26 is in a straight line. The other end of the hook bolt 3 is inserted into a bolt hole of a stand 31 fixed to the lower frame 3 and a wing nut 32 is screwed into the hook bolt 29.
3 and is tensioned.

As shown in FIGS. 1 and 5, the rope car 24
A turning rope wheel 36 is rotatably fitted into a shaft 35 fixed to a stand 34 erected on the lower frame 3 on a line orthogonal to the vicinity of the center of the shoji screen 13. A wire rope 41 whose end is locked to a hook bolt 40 inserted through and screwed into a wing nut 39 faces toward the upper drive rope wheel 17, which is wound at least half a turn around the rope wheel 24 so as not to slip, and is parallel to the upper drive rope wheel 17. It is wound several times around the rope wheel 17 so as to be hooked, then facing the turning rope wheel 36 so as to be parallel, it is wrapped about 180 degrees around the turning rope wheel 36, and then reversed and facing the rope wheel 24. It is wrapped around one and a half turns or more to prevent it from slipping, and the ends are locked to the stand 34 so that they are hung parallel to each other.

Here, the rope pulleys 23 and 24 are selected so that the wire ropes 26 and 41 wound thereon have the same center diameter. Therefore the wire rope 26,4
1 have the same thickness, they have the same diameter. The wire ropes 26 and 41 are wound in the same direction around the rope pulleys 23 and 24. That is, as shown in FIG. 1, the wire ropes 26 and 41 appear to be wound to the left around the rope sheaves 23 and 24 when viewed from the shaft end side.

The drive shaft 18 is suitably provided with a drive system from the ground so that it can rotate from the ground. For example, the drive shaft 18
A wire rope 45 is wound between the end rope sheave 22 and a rope sheave 44 fixed to an output shaft 43 of a speed reducer 42 parallel to the end rope sheave 22. When the handle 46 fixed to the input shaft of the reducer 42 is rotated, the output shaft 43 rotates at a reduced speed, the rope wheel 44 rotates, and when the rope wheel 22 rotates via the wire rope 45, the drive shaft 1
8 is something that rotates.

Drainage from the roof 1 is not shown, but an internal gutter is suitable.

When the handle 46 is rotated, the drive shaft 18 is rotated, and the drive rope pulley 17 is rotated. When the handle 46 is rotated so that the drive rope sheave 17 is rotated counterclockwise in FIG. The wire rope 41 following this extends from the rope sheave 24 and is tied to the hook bolt 40, so that the rope sheave 24 is rotated counterclockwise as shown in FIG. On the other hand, the wire rope 41 extending from the lower side of the drive rope sheave 17 is wound around the turning rope sheave 36 , wrapped around the rope sheave 24 , and further connected to the stand 34 . The wire rope 41 between the turning rope car 36 and the rope car 24 is wound around the rope car 24 by the amount that is pulled and unwound from the rope car 24.
The wound portion is let out from the lower side of the rope car 24 to the stand 34. Therefore, the rope pulley 24 rotates counterclockwise and moves in the direction of arrow 48 in the figure. When the rope wheel 24 rotates and moves, the rotating shaft 14 also rotates and moves.

As the rope wheel 23 rotates and moves counterclockwise as shown in FIG.
Wind up the wire rope 26 on the side that is locked on the hook bolt 33.
Let out. Therefore, the rotating shaft 14 moves in the direction of the arrow 48, and the shoji 11 moves through the bearing 15 as shown in FIG.
In FIG. 5, move in the direction of arrow 48 and open the upper part of the eave beam of the cross beam 5 to open the eaves part,
Furthermore, the indoor side is opened. When the bearing 15 hits the lower end of the shoji 12, the shoji 11 and 12 move together, and the shoji 1
Shoji 12 is placed under 3 and overlaps. The maximum opening area is the position where the end of the bearing 15 touches the shoji 13 or where the upper end of the shoji 12 stops (depending on design dimensions).

When the handle 46 is turned in the opposite direction and the drive rope pulley 17 is rotated clockwise in FIG. 36, the rope wheel 24 is rotated clockwise to advance in the direction opposite to the arrow 48. At this time, the wire rope 41, which is wound around the drive rope sheave 17 and let out from above, is wound around the rope sheave 24 and let out from the bottom of the rope sheave 24 toward the hook bolt 40. While rotating in the direction, it moves in the opposite direction to the arrow 48.

In FIG. 4, when the rotating shaft 14 rotates clockwise and moves in the opposite direction to the arrow 48, the hook bolt 3
The wire rope 26 on the side latched to the hook bolt 29 is wound onto the rope pulley 23, and the wire rope 26 on the side latched on the hook bolt 29 is let out. Therefore, the bearing 15 moves in the direction opposite to the arrow 48, and the shoji 11
will also move together. When the ridges 11-1 of the shoji 11 engage with the ridges 12-1 of the shoji 12, the shoji 11 pulls the shoji 12 and moves in the same direction, and when the end of the shoji 11 hits the lower frame 3, the upper side of the shoji 12 The ridges 12-2 abut or approach the ridges 13-1 of the shoji 13, and the shoji 11, 12 are closed.

Rope wheels 23 having the same diameter as the rotating shaft 14 supported by bearings 15 fixed to the shoji 11 are arranged at appropriate intervals on the roof, and both ends of wire ropes 26 wound around the rope wheels 23 are attached to the upper frame 2, respectively. Since it is fixed on the lower frame 3 side, the rotating shaft 14 moves in parallel very accurately. Therefore, even if the rotating shaft 14 is thin, it has little deflection and does not become strained. This also means that even if a large number of bearings 15 are arranged, the axis can be maintained, and since no unreasonable force is applied to the shoji 11, the shoji 11 can also move in parallel accurately. Since the wire ropes 26, 41 are wound around the rope wheels 23, 24, 17 with the same twist, as the rotating shaft 14 moves toward the center of the roof 1, the rotating shaft 14 slides through the bearing 15 in the axial direction. do. However, since the wire ropes 26 and 41 are wound in the same direction, the wire ropes 26 and 41 move in parallel in the same direction.

The rope pulleys 23 and 24 are fixed to the rotating shaft 14 with set screws 25. This effect is effectively exhibited during assembly and adjustment. That is, if the rope pulleys 23 and 24 are fixed to the rotating shaft 14 from the beginning, the tension of the wire rope 41 can be adjusted as shown in FIG. 5, but the position of the rope pulley 24 cannot be adjusted. Wire rope 2 based on rope car 24
When adjusting the tension and position of 3 using the nut 28 and wing nut 32, it is difficult to tell whether the long flexible rotary shaft 14 is bent or not. However, the rope pulleys 24 and 23 in the present invention can freely rotate on the rotating shaft 14 if the set screw 25 is loosened.
Therefore, if the position of the rotating shaft 14 is maintained accurately and the wire ropes 26, 41 are stretched, the rotating shaft 14 will not receive any force, so there will be no risk of bending, and it is only necessary to equalize the tension of the wire rope 26. . After adjusting in this manner, tighten the set screw 25.

FIG. 6 is a perspective view showing another embodiment of the method for driving the rotating shaft 14. The only difference from the above embodiment is that the way the wire rope 41 is hung on the rope pulleys 17, 24 and the turning rope pulley 36 is the same as in the above embodiment. The rope wheel 24 is rotatably attached to the rotating shaft 14 via a bearing 50. The rope pulley 24 is pulled by the tensile force of the wire rope 41 in the direction of arrow 51 or arrow 52 depending on the direction of rotation of the drive shaft 18, and the rope pulley 24 rotates in the direction of arrow 53 or arrow 54, which is the same as the previous embodiment. It is. Since there is a bearing 50 there, the rotating shaft 14
Rotating shaft 14 is moved in the direction of arrow 51 or 52 without transmitting rotational force to . Then, as shown in FIG. 4, the rope wheel 23 tries to move in a direction perpendicular to the rotation shaft 14, but since it is restrained by the wire rope 26, it has no choice but to rotate, and therefore, the rotation of the rotation shaft 14 This ensures parallel movement.

Note that the method of driving the drive shaft 18 is merely an example; for example, the output end of a motor with a worm reduction gear fixed to the drive shaft 18 may be attached to the drive shaft 18, and a push button may be operated from the ground via a control device. . Furthermore, the drive system up to the rope car 24 may be eliminated and the rotating shaft 14 may be driven by a reduction motor mounted on the shoji 11.

FIG. 7 is a perspective view of the continuous windows near the factory building seen from the inside. In the figure, the reference numerals assigned to the above-mentioned embodiments are attached, and the part corresponding to the roof 1 is erected to form continuous windows, an opening/closing device is provided on the inside, and the drive shaft 18 is common to each window. It is something.

As described above, according to the opening/closing device for building openings of the present invention, the shoji is pulled and the shoji is parallel to the rotating shaft which is disposed orthogonally to the moving direction of the shoji and supported by bearings set upright on the shoji. A rope wheel 23 is arranged, and wire ropes wound around the rope wheel so as not to slip are stretched in a straight line in opposite directions, so that the rotating shaft moves in parallel and the shoji also moves in parallel.
The rotating shaft is supported by parallel wire ropes, so it does not bend easily even though it is thin. The rope pulley 23 attached to the rotating shaft can be attached after being made freely rotatable in the direction of rotation, so attachment is extremely easy.

The drive device extends the wire ropes wound around the driving rope wheel in the same direction, and at the same time, one wire rope is wound directly around the rope wheel 24 provided on the rotating shaft, and at the same time, the other wire rope is reversed and wound around the rope wheel 24 from the opposite direction. Since each end of the rope was fixed by extending from the rope wheel 24 to the same side as the side where it was wrapped around the rope wheel 24,
The wire rope and the rope wheel work together without slipping, and the wire rope 26 wrapped around the rope wheel 23 described above
In addition, it is constructed entirely of wire ropes and rope wheels, making it inexpensive and durable. The examples are skylights and continuous windows, but the device can also be used as a moving device for a shoji screen on one side of a vertical window, and has a wide range of applications.

FIG. 8 is a perspective view showing another embodiment of the invention. In this embodiment, the shoji in FIG. 1 is a part of the cylindrical shape, and is configured as a dome for lighting. An arcuate frame 56 is fixed to the roof 55. The frame 59 engages with the frame 56 so that a shoji 58 in which a glass 57 shaped as a part of a cylinder is fitted into the frame 59 moves in an arc shape along the frame 56. ing. Glass 61 is fixed to the outside of the shoji 58 in a tight fit. Inside the frame 56 is a substantially semicircular glass 62. A bearing 15 is fixed on the shoji 58.
A rotating shaft 14 is disposed parallel to the axial direction of the shoji 58, and a rope wheel 23 is fixed to the rotating shaft 14. A wire rope 2 is attached to the rope car 17.
6 is wound and the ends extending in opposite directions are stretched in contact with glasses 57 and 61, and the opening frame 6
3,64. It is appropriate that the rotating shaft 14 is driven by a reduction motor 65 fixed to the stile 59 of the shoji 58.

When the reduction motor 65 rotates, the rotating shaft 14 rotates, and the rope wheel 23 rotates. The rope car 23 moves in a rolling manner by winding up and letting out the wire rope 26. As the rotating shaft 14 moves, the bearing 1
5, the shoji 58 is guided by the frame 56 to open and close. Therefore, the ceiling dome not only allows sunlight but also ventilation.

In the embodiment, the shoji was made as a single piece in the width direction of the opening frame, but for example, in FIG. ' with grooves 4-1, 4-2, 4 similar to the vertical frame 4
Shoji 11, 12 as intermediate vertical frame 4' with -3
Alternatively, the shoji 13 of the fitted shoji may be divided in the width direction so that it can be slid between the vertical frame 4 and the intermediate vertical frame 4', and between the intermediate vertical frames 4'.
