Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a shoji screen equipped with a sunshade that extends upward from below.

(Prior art) The purpose of a sunshade that is usually attached to or built into a shoji is to block sunlight that hits the window surface;
Another method is to cover the windows so that the interior cannot be seen from outside. In conventional windows with built-in Veneshia blinds, the blinds are suspended from the upper frame of the shoji screen, so in order to block the hands that you want to hide the most or the lower part of the window that you want to protect from sunlight, you can lower the blinds all the way down and use the blades. had to be fully closed. Therefore, in this case, the room would be dark and lighting would be necessary.

In order to improve these drawbacks of shoji, in double-glazed windows, a winding shaft is attached along the lower frame of the shoji, and a guide string that is wound around this and a lifting string that is fixed to the top plate are used to pull the shoji upward from the bottom. The same applicant has proposed a system in which a sunshade is housed between indoor and outdoor glass. (Unexamined Japanese Patent Publication 1973-
(No. 30022) (Problems to be Solved by the Invention) However, in the above-mentioned Japanese Patent Application Laid-open No. 55-30022, the lifting cords must be fixed to the upper left and right ends of the upper plate due to the structure, so the lifting cords are The winding shaft that winds up the guide string is located below the lower frame, so the height of the shaft box that stores the winding shaft is limited by the daylighting area of the window. In addition, the force to raise the awning increases as the awning rises, making the tension on the lifting string unstable, and there is a risk that the guide string may break due to changes in the tension of the coil spring applied to the guide string. be. Furthermore, when the shoji is open and in an inclined position, there is nothing to support the top plate between the double panes of glass, and as the awning rises and falls, the top plate and the awning itself come into contact with the glass surface, inhibiting its movement. This may cause a malfunction.

Therefore, the present invention aims to improve the above-mentioned drawbacks of the conventional ones, and makes it possible to smoothly raise and lower the upper plate of a shoji shoji with a sunshade that can be pulled up from the bottom upwards, and also to increase the daylight area of the shoji and prevent the sunshade from rising. The purpose is to stabilize the operation by keeping the tension of the hit lifting string constant and to avoid applying large tension to the guide string.

(Means for solving the problem) For this purpose, in a shoji equipped with an awning that moves up and down along the shoji surface, both ends of the upper board of the awning are inserted so as to move up and down within guide rails provided along the vertical frame of the shoji. and attach one end of the guide string to the upper plate,
The guide string passes through each wing piece, passes through the lower plate, and then inside the guide rail, is reversed by being given tension by the tension part provided in the upper frame of the shoji, returns to the guide rail again, is connected to the upper plate, and is connected to the inside of the guide rail. Each of the pulling strings connected to both ends of the upper board is tied together outside the shoji frame.

(Embodiment) An embodiment of the horizontal axis rotating window of the present invention shown in the drawings will be described. In Figs. 1 to 3, reference numeral 1 denotes a fixed frame of a window which supports a shoji 2 by means of a rotating shaft 3, and the shoji 2 is rotated in the direction of arrow A and opened. In this embodiment, a hollow layer 16 is formed by an outer glass 6 and an inner glass 7, and 5 is a translucent cloth sunshade built into the hollow layer 16. FIG. 1 is a front interior view showing a state in which the sunshade 5 is raised to approximately the height of the lower half of the shoji 2 by the two pulling strings 9 and 10 of the sunshade 5. The pulling strings 9 and 10 are tied to a stopper 11 attached to the indoor side of the right shoji frame 19, and the sunshade 5 is stopped at this position. The sunshade 5 has an upper plate 8 at the upper end of the sunshade 5 and a hollow part 12a at the lower end in the hollow layer, as shown in FIG. 3 showing a longitudinal section and FIG. The forming lower plate 12 is fixed.
The sunshade 5 has alternating folds 14, 15, etc., so that its wing pieces 5a can be folded freely. Along the inside of the left and right frames 18 and 19 of the shoji 2, as shown in FIGS. 23 is formed as a rising member with openings 20 and 21 facing each other from both ends of the lower frame 13 of the shoji 2, and is connected so as to communicate with the hollow part of the lower plate 12. That is, the lower plate 12 of the awning is fixed to the lower frame 13 of the shoji 2, and its left and right ends 24 and 25 are inserted across the openings 20 and 21 of the rails 22 and 23, respectively, as shown in FIG. They are connected at a position that extends close to the bottom surface 17 of the rail. On the other hand, the upper plate 8 has a length that allows it to move up and down within the width of the hollow layer 16, and the width of the awning 5 is also the same, and the height is such that each fold 14, 15 is opened and the shoji 2
long enough to cover the entire height of the Guide bodies 30 made of synthetic resin are provided at the left and right ends 28 and 29 of the upper plate 8,
31 are provided in a protruding manner, and the guide bodies 30, 31 are inserted and engaged into the hollow portions 26, 27 of the left and right rails 22, 23 through the openings 20, 21 of the rails, respectively. Thereby, the upper plate 8 is guided in the vertical direction within the hollow layer 16 while being kept horizontally. Guide string 34, 3 for sunshade 5
5 has one end 53, 55 connected to the lower surface 48 of the upper plate 8.
The lower plate 12 is fixed to the sunshade 5 and sequentially passes through the left and right through holes 32 and 33 between the folds 14 and 15 of the sunshade 5.
It enters the hollow part 12a, splits into left and right parts here, exits through through holes 36 and 37 provided in the ends 24 and 25 of the lower plate 12, and enters the hollow parts 26 and 27 in the rails 22 and 23, respectively. It is directed upward along the bottom surface 17 and taken out to occupy positions 34a and 35a. As shown in FIGS. 4 to 6, on the lower surface of the right end of the upper frame 38 of the shoji 2, there are groove wheels 39, 40 arranged in parallel along the shoji surface, and a pulling string 9, on the upper part thereof.
A roller bracket 41 that rotatably supports the guide groove wheel 50 for 10 is attached, and these groove wheels 39,
40 is located above the hollow part 27 of the rail 23. Similarly, integrated groove wheels 42 and 43 are provided at the left end of the upper frame 38 of the shoji 2 at positions substantially symmetrical with the group of groove wheels on the right side, and above the groove wheels 42 and 43 are provided a guiding groove wheel 44 for the pulling string 9.
A roller bracket 45 is attached to rotatably support the. As described above, the guide string 34 taken out into the hollow part 26 of the rail 22 and extending upward changes its direction horizontally through the groove wheel 42 toward the center of the lower side of the shoji upper frame. On the other hand, a tension spring 46a fixed to a suitable support point 49 on the upper frame 88
A tension groove wheel 47a is provided which is always pulled toward the center by the horizontal guide string 34.
By this tension groove wheel 47a, the direction is changed again in the direction of arrow G in FIG.
34 and then enters the aerial part 26 of the rail 22 again.
Descend to the position indicated by b. Both ends of the upper plate 8 are provided with guide bodies 30 and 31 that are fitted into the openings 20 and 21 of the rails 22 and 23, respectively, and the end 52 of the guide string 34 is fixed to the guide body 30 at the lowered position 34b. . That is, both ends 52 and 53 of the guide string 34 are formed into an endless shape, with the upper plate fixed to the upper and lower surfaces of the upper end plate 8 and sliding up and down along the opening of the rail serving as connecting parts. The guide string 35 on the right side also connects to the groove wheel 3 in exactly the same way.
9. The end portion 54 is fixed to the guide body 31 at the right end of the upper plate via the tension groove wheel 47b and the groove wheel 40, and is configured in an endless shape. Similar to the left side, this tension groove wheel 47b is constantly pulled toward the center by the upper frame 38, and thus the guide strings 34, 35 are always kept under tension so that they do not loosen. Furthermore, one end 57 of the pulling string 9 is fixed to the guide body 30 on the left side of the upper plate 8, and the pulling string 9 passes through the hollow part 26 of the rail 22, passes through the groove wheel 44, and then reaches the guide groove wheel 50 on the right side. It is drawn out to the outside of the hollow layer 16 through. The other pulling string 10 also has its one end 58 fixed to the guide body 31 at the right end of the upper plate 8, and the rail 2
The guide groove wheel 50 is suspended through the hollow part 27 of the cord guide 4 and then pulled out to the outside of the hollow layer 16. , 4b, each end is tied to a knob 56.

The shoji according to the invention with a sunshade that rises from below has the above-mentioned configuration, and when the sunshade 5 is folded at the bottom of the shoji as shown in FIG. 5, the knob 56 can be pulled in the direction of arrow B. For example, the pull strings 9 and 10 tied to this are connected to the cord guide 2.
The pulling cord 9 passes through the guide groove wheel 50 through the rollers 4a and 4b, and further passes through the groove wheel 44 to the upper plate 8.
The pulling string 10 applies a lifting force to the left guide body 30 and the guide body 31 at the right end of the upper plate 8, respectively, and both are guided by the openings of the rails 22 and 23 and rise. Therefore, the upper plate 8 is pulled up in the direction of the arrow Q, and the sunshade 5 is successively unraveled and raised. At this time, the guide strings 34 and 35 passing through the through holes 32 and 33 of each wing piece are endless with the upper plate 8 as a contact point. Since the upper plate 8 is configured in a shape, the guide string for the upward movement of the upper plate 8 advances in the direction D in the hollow part of the rail, and is successively retracted from the through hole of the lower plate 12, and the upper plate 8 is connected to the guide bodies 30, 3.
1 to the respective rails and rise to the position shown in FIG. 6, where the awning 5 covers the entire surface of the shoji 2. During this time, the guide strings 34 and 35 are kept under constant tension by their respective tension groove wheels, so they do not bend under their own weight, and can maintain a state parallel to the glass surface while expanding the sunshade blades. . Therefore, it is only necessary to pull up the awning to an arbitrary raised position using the pulling strings 9 and 10 and fix it to the stopper 11.
0 from the stopper, the upper plate 8 will fall in the direction of arrow E under its own weight as shown in Figure 6, and each wing piece of the sunshade 5 will fold up by the folds 14 and 15, contrary to when it rose. Since each guide string 34, 35 is always under tension due to the tension groove wheel, the lower plate 12
It is possible to proceed in the direction of arrow F through the hollow part of the rail communicating with the sunshade 5 and return correctly to the folded position shown in FIG. 5 without protruding from the surface of the sunshade 5.

(Effects of the Invention) As described above, in the awning shoji of this invention, the awning rises from the bottom upwards, so when the awning 5 is raised to the majority of the window as shown in FIG. It allows you to enter only from the outside and shield your immediate area, and it also hides the movement of the main part of the room and the parts close to the window from the outside. In FIG. 9, which shows a conventional example, in order to block solar radiation, all the blinds must be lowered and the blades must be fully closed. Also, as shown in Figure 10, with conventional windows, it was not possible to open the shoji at a certain angle and operate the Venetian blinds, but if the shoji of this invention is adopted, the shoji can be opened as shown in Figure 8. Even when the shoji 5 is moved up and down, the guide body of the upper plate is always restrained by the rail and the guide string is kept in tension by the tension groove wheel without sagging. The awning can be raised and lowered smoothly in parallel, and since there is no winding shaft below the lower plate, the lighting area of the shoji can be increased, and the pulling strings that run up and down inside the guide rails are not exposed to view. Furthermore, since no extra tension is applied to the guide string, there is no risk of the string breaking, and other remarkable effects are achieved.
