Description

[Detailed Description of the Invention] The present invention relates to an inversion sash that uses a link mechanism to allow the shoji to be inverted within a window frame without having to take it out into the room.

Reversing the shoji screen is an extremely important function in terms of maintenance of the exterior surface of the room, especially in making it possible to safely clean the exterior surface of the window glass from the interior side.

This type of reversible sash has a movement axis at one end of the shoji inside the window frame that can be moved along the longitudinal direction within the expected dimensions of the window frame, and one end of the arm that rotates around the center of the frame of the shoji. The arm is attached freely, and the other end of the arm is rotatably supported on the window frame.
When the movement axis of one end of the shoji moves from one end of the window frame to the other end, the shoji rotates relative to the arm and attempts to reverse itself by switching between the indoor side and the outdoor side.
At the time of this reversal, the shoji and the arm overlap within the window frame, and at this time, the movement axis of the shoji and the arm of the window frame interfere with each other on substantially the same plane, so that the shoji cannot be completely reversed.

This interference can be eliminated by providing the arm and the movement axis at different heights. However, if this is done, the structure for attaching the window frame and the arm becomes complicated, and sufficient strength cannot be obtained. Also, by bringing the support shaft out of the window frame to the outside,
Interference between the arm and the movement axis can be avoided. However, if the support shaft is brought out to the outside of the room, the appearance of the sash will be impaired, which is undesirable.

The purpose of this invention is to completely invert the shoji by making use of the interference between them that occurs when the shoji is inverted, while keeping both the arm support axis and the movement axis of the shoji within the expected dimensions of the window frame. There is.

Based on the above purpose, the inverted sash of the present invention is provided with a moving axis at the vertical position of one side end of the shoji placed inside the window frame, and this moving axis is moved in the longitudinal direction of the upper and lower frames of the window frame. It is movable along guide parts provided on mutually facing surfaces, and has a contact part with the moving shaft by a support shaft installed within the expected dimensions of the window frame at the upper and lower positions of the corner part of the window frame. One end of the first arm is rotatably attached, and one end of the second arm is rotatably attached to the central part of the upper and lower stile of the shoji by a rotating shaft, and this second arm is connected to the first arm by a connecting shaft. A stopper is rotatably connected to the arm and is provided on the first arm or the second arm to prevent the second arm from rotating in the direction toward the outdoor side around the connecting shaft from a state in which the second arm is in line with the first arm. By bending the first arm and the second arm at the connecting shaft part when the first arm and the moving shaft come into contact with each other when reversing,
The movement of the movement axis of the shoji is not restricted by the presence of the arm.

Hereinafter, the present invention will be specifically explained based on an embodiment shown in the drawings.

As shown in FIGS. 1 to 6, the inverted sash 1 of the present invention has a window frame 2, a shoji 3, and a first arm 4 and a second arm 5 as main parts.

The window frame 2 is located above and below the left and right vertical frames 6 and 7.
The upper frame 8 and the lower frame 9 are fixed. Guide grooves 10 and 11, which serve as guides for moving shafts to be described later, are formed in the opposing surfaces of the upper frame 8 and the lower frame 9, respectively, extending in the longitudinal direction. This guide groove 1
The end portions 0 and 11 are bent toward the indoor side, as shown in FIGS. 5 and 6. In addition, the above window frame 2
is equipped with an annular gasket 12 that contacts the shoji 3 along the opening edge on the indoor side. Further, rain restraining pieces 13 are attached to the left and right sides and the upper part of the window frame 2 on the outdoor side.

Shoji 3 has upper stile 16 between vertical stile 14 and 15.
and a lower stile 17 are combined into a framework. A plate glass 20 is fitted into the shoji 3 from one opening surface using a ridge 18 and a gasket 19. In addition, a handle 22 is rotatably attached to the indoor side and the outdoor side of one of the vertical stile 14 by a shaft 21, and a lock plate 23 attached to the shaft 21 is inserted from the hole 24 of the vertical stile 14. protruding,
Lock body 25 attached to the prospective surface of the vertical frame 6
It is in a state where it can fit into the lock groove 26 of the. In addition,
The lower stile 17 integrally forms a handle portion 27 on the indoor side and the outdoor side.

Now, two support shafts 28 are attached to the mounting brackets 2 on the same vertical line on the lower surface of the upper frame 8 and the upper surface of the lower frame 9 near the vertical frame 6, that is, near the corner of the window frame 2.
It is attached by 9. This support shaft 28 is within the expected dimensions of the window frame 2 and rotatably supports one end of the short first arm 4. The first arm 4 has a length that allows it to come into contact with a moving shaft to be described later, and its side end surface serves as a contacting portion with the moving shaft. On the other hand, a relatively long second arm 5 is rotatably attached to the center of the upper stile 16 and lower stile 17 of the shoji 3 by a rotating shaft 30. This rotating shaft 3
0 are each fixed to the center portion of the shoji 3 by mounting fittings 31. The first arm 4 and the second arm 5 are rotatably connected by a connecting shaft 32, respectively. Note that the first arm 4 has a stopper 33 formed by a bent piece on its end edge. This stopper 33 restricts the rotation of the second arm 5 from the linear state of the first arm 4 toward the outdoor side (upward in FIG. 5) about the connecting shaft 32. Further, as shown in FIG. 7, the first arm 4 and the second arm 5 are provided with a recess 39 and a protrusion 40 that are removably fitted into each other. When these are fitted together, the first arm 4
and holds the second arm 5 in a straight line. Furthermore, since the mounting bracket 29 is provided with a cover plate 41, the first arm 4 is prevented from rotating more than necessary.

Further, moving shafts 34 are respectively attached to upper and lower positions of the shoji 3 on the side different from the supporting shafts 28. This moving shaft 34 is connected to the corresponding guide grooves 10 and 11, respectively.
The slider 35 is made of a material with a low coefficient of friction, such as plastic, and is slid on the slider 35. These sliders 35 both have stepped sliding surfaces 36, but the lower slider 35
hits the upper surface of the guide groove 11 with its sliding surface 36,
It supports the weight of Shoji 3. Note that a receiving member 37 is attached to the vertical frame 7, and this receiving member 3
7 is in contact with a pulling piece 38 attached to the vertical stile 15.

Next, the function and operation of the above-mentioned reversing sash 1 will be described in the 8th section.
This will be explained based on the diagram. When closed, the shoji 3 is in contact with the gasket 12 of the window frame 2 and closes the opening surface of the window frame 2. The pressing force of the shoji 3 at this time is achieved by the engagement between the lock plate 23 and the lock groove 26 and the contact between the receiving member 37 and the pulling piece 38. In this state, the upper and lower first arms 4 and second arms 5 are almost in a straight line, as shown in FIG. There is.
When the shoji 3 is reversed, the operator
While pressing the end of the shoji 3 on the support shaft 28 side from the indoor side toward the outdoor side, the upper and lower moving shafts 34 are moved along the direction of the guide grooves 10 and 11 toward the support shaft 28 side. In this way, the shoji 3 rotates counterclockwise around the upper and lower rotation shafts 30, as shown in FIG. 8B, and the upper and lower first arms 4 and second arms 5 move in a straight line. It then rotates clockwise around the support shaft 28. At the time of this rotation, the end of the shoji 3 on the opposite side to the moving shaft 34 protrudes toward the outside of the room. When the moving axis 34 passes the intermediate position,
The shoji 3 switches its outdoor surface and indoor surface, and is in an inverted state. While the vertical moving shaft 34 approaches the support shaft 28, the moving shaft 34 comes into contact with the side end surface of the first arm 4 together with the slider 35, as shown in FIG. Since it is bent toward the indoor side from the contact position, the moving shaft 34 moves along the bending direction. At the same time, the first arm 4 and the second arm 5 are connected to the connecting shaft 3 as shown in FIG. 8C.
2 is bent in a dogleg shape, and the connecting shaft 32 is deviated toward the outdoor side from the line connecting the support shaft 28 and the rotating shaft 30. In this state, the shoji 3 is completely reversed, and the paper 1
It will be in contact with 2. Of course, the drawing of the shoji 3 at this time is achieved by the lock plate 23 and the drawing piece 38 engaging with or abutting on the receiving member 38 and the lock plate 25, respectively. In this way, the moving axis 34, the first arm 4
The second arm 5 and the second arm 5 are in a relationship that interferes with each other on substantially the same horizontal plane, but due to this interference, that is, the contact between the first arm 4 and the moving shaft 34, the first arm 4 and the second arm 5 are connected to the connecting shaft 32. Bent in some parts,
This makes it possible to completely flip the shoji 3. In addition, when returning the reversed shoji 3 to its original state,
The operations described above are reversed. Furthermore, since the first and second arms 4 and 5 are restricted from bending in the opposite direction to the above-mentioned movement by the stopper 33, when opening and closing the shoji 3, the same movement as when using one arm is performed. do the work.

In addition, in the above embodiment, the moving shaft 34 is connected to the guide groove 1.
Although the slider 35 is interposed between 0 and 11 to form a sliding pair, the pair may be a rolling pair using wheels or the like. Also, the rotating shaft 30
is provided almost at the center of the shoji 3,
If the effective lengths of the first arm 4 and the second arm 5 are equal to the center of the rotating shaft 30 and the center of the moving shaft 34, reversal operation is possible, so the mounting positions of the rotating shaft 30 and the supporting shaft 28 are It is not limited to those of

As explained above, the inverted sash of the present invention has a moving axis at the vertical position of one side end of the shoji placed inside the window frame, and this moving axis is moved in the longitudinal direction of the upper and lower frames of the window frame. It is movable along guide portions provided on opposite sides of the window frame, and the abutting portion with the moving shaft is controlled by a support shaft installed within the estimated dimensions of the window frame at the upper and lower positions of the corner portion of the window frame. At the same time, one end of the first arm is rotatably attached to the upper and lower stile of the shoji, and one end of the second arm is rotatably attached to the central part of the upper and lower stile of the shoji by a rotation shaft, and this second arm rotatably connected to a first arm, and to the first arm or the second arm;
A stopper is provided to prevent the second arm from rotating in the direction toward the outdoor side around the connecting shaft from a straight line with the first arm, so that when the shoji is reversed, the axis of movement at one end of the shoji moves between the first and second arms. However, by making good use of this interference and bending the first and second arms, it is possible to move the axis of movement, so the shoji can be completely reversed with good operability. Moreover, the supporting shaft and the moving shaft can be arranged on substantially the same plane and within the estimated dimensions of the upper and lower frames, which simplifies the structure accordingly. Therefore, in the present invention, there is no need to attach the supporting shafts and the moving shafts to different upper and lower planes, and the structure of the shoji, especially the upper and lower frames of the shoji and the upper and lower frames of the window frame, can be simplified. Furthermore, since the link mechanism is completely housed inside the window frame, the appearance of the reversing window is simplified and its design is not impaired.
