Description

[Detailed Description of the Invention] Due to the opening/closing structure of sliding windows such as well-known sliding windows, is it easy to clean the indoor glass surface of Rakumado Shoji, or does it require a cleaning person to clean the outdoor glass surface? Cleaning work is difficult as the worker has to extend half of his body out of the window, and if the window shoji is large, the VC may not be able to reach the entire surface, making it impossible to clean the entire surface of the glass. When sliding windows are installed at a high location, it is extremely dangerous to stick half your body out of the window as described above.

In view of these points, the present invention can be used in the same way as ordinary sliding windows, but each window shoji can be easily opened inward when cleaning the glass surface of the window shoji. It provides a window structure.

Hereinafter, one embodiment of the present invention will be described based on the drawings. In FIG. 1, 1 indicates an upper frame 2, a lower frame 3, and left and right side frames 4.
This is a window frame that houses a pair of window shoji 5.6. As shown in Fig. 2, the upper part of this window frame 1 has horizontal wall parts 2b and 2c in the form of a step, with the entire height on the indoor side between the weir wall 2ak, and from the horizontal wall part 2b on the lower side to the upper side. An upward hook-shaped guide rail 7a protrudes toward the side wall portion 2c, and an upward hook-shaped kite rail 71) extends downwardly from the hanging wall portion 2d formed on the outdoor side of the upper frame 2 toward the lower side wall portion 21). is installed protrudingly. Upper Vc of the horizontal wall portion 3a of the lower frame 3
Kite rails 3b and 3c are protruded from each of the horizontal walls 21) and 2C of the upper frame 2 (id1), respectively, and an ice wall 3d (11) is erected on the indoor side of the lower frame 3. 8.
El:t Between the kite rails 3b and 3c, and between the kite rail 3c and the II-water wall part 3 (1), the horizontal wall part 3
71 (drilled hole shown) drilled in a
The drainage chamber 9 is connected to the outside air through a drainage hole 10 directly below the side wall.On the other hand, there are downward hooks on the sides of the upper frames 5a and 6a of each window shoji 5 and 6d, respectively. engaging strips 5b, 6b are provided, so that the inner and outer window sills 5.6 engage the engaging strips 5b, 6b with the force rails 7a, 7b of the upper frame 2, and the lower frame 5c, 6c is mounted on the kite rail 311.3C via a door roller, and each window shoji 5, 6 can be opened and closed in the sliding direction.At this time, the window shoji 5 and the horizontal wall portion 2b directly above it are attached. A required gap 11.11 is provided between the window shoji 6 and the horizontal wall portion 2c directly above it, so that each window shoji 5, 6 can stop the water in the lower frame 3 during the window shoji lifting operation described later. It is configured so that it can rise to a position beyond the wall portion 3d.Also, as shown in FIG. , 6d, seal engagement protrusions 12, 13 are provided over the entire height range of the vertical stile, and when the face-butted shoji 5+6 is in the closed position, the seal engagement protrusions 12 and 3 engage with each other to make it watertight. It is designed to be maintained.

Next (to explain the inward opening structure of the shoji 5 and 6),
As shown in the figure, the vertical grips Sd on the joining part side of each window shoji 5, 6,
A movement direction changing means 20, which will be described later, is provided within the movement direction 6d. That is, as shown in FIGS. 5 and 6, the vertical stile 5
A cage-shaped inner cylinder 14 is heavily fixed inside d and 6d,
A rotor 15 is rotatably supported inside the inner cylinder 14, and a sliding body 16.
+7 is fitted inside so that it can be raised and lowered, and one end of these sliding bodies 16 and 17 is connected to the eccentric position of the rotor 15 or by a link +8i9&'c, so that the rotor 150 rotates (therefore, the sliding bodies +6 and 17 are moved in a straight line) Motion direction changing means 20 that slides in a shape
is constructed, and each IS moving body 16.1 of this conversion means 20
Bearing arms 23 and 24, which are movable up and down, are attached to the free ends of the shafts 7 via irons 21 and 22, respectively. As the rotor 15 is rotated in one direction, both sliding bodies 16 and 17
is pressed and slid in the direction away from the rotor 15,
Each bearing arm 23, 24 moves toward the upper and lower ends of the window sills 5, 6, and is continuously drawn in by a rotation T'15.

In this way, for the rotation operation of rotation r-15, rotation
51CI・A square hole 25 for inserting a rotary operating tool is provided at the axial center position iη of the trunk, and the square hole 25 is connected to the inner cylinder 14 and the vertical frame 5.
It is exposed to the window sashes 5, 6 through the openings 26, 26 (see Fig. 3) of d and 6d, and in this case, as shown in Fig. Alternatively, the lever handle 27 may be integrally removed.

Further, when the window shoji 5, 6 is in the normal closed position shown in Figs. Horizontal wall portion 2b of frame 2, 2
Bearing arms 23 and 2 are provided on the side wall portion 33 of the lower frame 3 and the lower frame 3, respectively.
Support shafts 28 and 29 are provided protrudingly corresponding to the upper frame side walls 2b and 2c, and the amount of protrusion of the support shafts 28 protruding from the upper frame side walls 2b and 2c is increased, and an elongated hole 30 is provided in the corresponding bearing arm 23. The amount of protrusion of the support shaft 29 (this support shaft 29 can be removed from the side wall 3aK via the mounting base 32 as appropriate) protruding from the other lower frame side wall 3a is reduced, and Corresponding bearing arm 24V
In c, a shallow recessed hole 31 is bored.

With this structure, the bearing arms 23 and 24 of each window shoji 5 and 6 are retracted into the VC window shoji 5 and 6 as shown in FIG. The hill portions are connected to the kite rails 7a, 7b and the engagement strips 5b, 6b +7
) By the engagement VC and the lower part is the kite rail 3b 3c
I'll be guided accordingly and can be used just like a normal sliding window.

After the window shoji 5 and 6 are closed in the opposite direction from the closed position shown in FIG. 8a, first move the lever handle 27 to the position shown in FIG.
As shown in FIG.
Due to the VC, the bearing arms 23 and 24 move outward VC, and the recessed hole 31 of the lower bearing arm 24 fits into the support shaft 29 of the lower frame 3 to support the bearing @24, and the upper bearing arm 23 long hole 3
0 (The support shaft 2B of the upper frame 2 is slightly fitted in, and as a result, these bearing arms 23 and 24 and the support shaft 28 fitted into this
, 29, the window sashes 5 and 6 are reliably prevented from moving inside the room, moving in the sliding direction, or falling off the window frame 1.As shown in FIG. When the lever handle 27 is rotated o0, the upper bearing piece 23
The upper frame shaft 28 is fitted deeper into the elongated hole 30 of the lower bearing piece 24, and the lower frame support shaft 29 is already fitted into the recessed hole 31t of the lower bearing piece 24, and the support shaft 29 supports the lower bearing part 24. As a result, the lower bearing part 24 pushes the lower frame support shaft 29 upward, and the reaction force causes the window shoji s, 6 V
c The lifting force acts to lift the window shoji 5.6 upward, and as shown in FIG.
At the same time, the engaging strips 5b+6b extend upward from the kite rails 7a and 7b of the upper frame 2 by τ7. Therefore, when the window shoji 5, 6 is lifted above the straight wall portion 3d of the lower frame 3, if you pull the window shoji 5, 6 toward the room, the upper and lower support shafts 2829 of this window shoji 5°6 It pivots around the center as a fulcrum and can freely open inward beyond the above-mentioned normal ice wall portion 3d, allowing it to be used as an inward-opening window.

As described above, according to the present invention, when the main use is as a sliding window such as a sliding window or a single sliding window, when cleaning the window, the sliding window can be opened inward at the open end position. Because of this, you can safely clean the window shoji without having to stick half of your body out of the window as in the past, and since the window opening can be fully opened by opening inward, large items can be taken in and out.

Still, according to the present invention, it is possible to use the window primarily as an inward opening window, and if necessary, it can be used as a sliding window.

Furthermore, the most important feature of the present invention is that bearing arms that move up and down relative to each other at the upper and lower ends of the window sash are installed in the vertical stile on the opening side of the window shoji, and the window frame at the opening end position of the window shoji is Support shafts into which the above-mentioned bearing arms fit are provided protrudingly on the upper and lower frames, and first each of these bearing arms moves RVP and fits into the support shafts of the upper and lower frames, and then the lower bearing arm moves to this VCC. The stroke amount of each bearing arm relative to each support shaft is set so that the support shaft is pressed and the reaction force of the pressure causes the window shoji to move upward four times. According to the present invention, when the window shoji is raised, the VC is already engaged with each bearing arm, the upper Azusa side bearing piece or the upper Azusa side support shaft, so when the window shoji is raised, the VC is already engaged with the upper Azusa side bearing piece or the upper Azusa side support shaft. Falling off from the frame can be reliably prevented.

Furthermore, as an additional effect, each bearing arm is already engaged with each support shaft before the window shoji is raised, so that at that point the window shoji opens inward in both the sliding direction (at this point, it opens inward). Window shoji are still in a so-called locked state, with the movement of the window frame (which is loaded with its own weight and cannot get over the lower frame water stop wall), so its main use is as an inward-opening window. When in use, this can be used as a lock when closing.
