Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a window whose shoji can be tilted inward and opened.

Prior Art In general, an inward-opening window with a shoji that can be tilted inward has one vertical stile and a lower stile attached to the window frame using hinges, and when used as an inward-opening window, the shoji is attached to the hinge on the lower stile side. The connection function with the window frame is released, and when used as an inward-folding window, the connection function between the shoji and the window frame using the hinge on the vertical stile side is released.

However, when this type of window is used as an inward-opening window, the connection between the shoji and the window frame by the hinge on the vertical stile side is released, and when used as an inward-folding window, the lower stile side When the function of connecting the shoji and the window frame using the hinge is released, the shoji can be folded inward and opened at the same time, but in this case, the shoji is only connected to the window frame with one hinge, which makes it unstable. And it's dangerous.

Purpose of the invention This invention uses a mechanism with a simple structure to prevent the connection between the shoji and the window frame by the hinge that connects the shoji and the window frame to be released when the window is open. The purpose of the present invention is to provide a casement window that can be tilted.

According to the present invention, the above object is achieved by providing strip-shaped operating rods connected to each other on both vertical and lower stile of a shoji, and moving the operating rod by engaging the operating rod with a hinge. At least two elongated holes having large diameter parts are formed in the operating rod provided in the vertical stile that is not hinged to the window frame so as to release the connection function by the hinge, and the lock pin is engaged in the elongated holes. This is achieved by preventing the movement of the operating rod by the locking pin when the window is opened.

In this drawing mechanism 100, the rotor 106 is positioned on the outdoor side of the drawing protrusion 103 and engages with the drawing protrusion 103 only when the operating rod 14 is at its lowest position with the window closed. The shoji 7 is brought into close contact with the mating surface of the window frame 1, and the shoji 7 is prohibited from opening. When the operating rod 14 is raised, the rotor 106 comes off the drawing protrusion 103 and the shoji 7 is prevented from opening. is allowed to open.

Next, the operation of this hinged window will be explained.

When the window is closed and the handle 9 is in the downward position as shown in FIG.
4 is at its lowest position, the operating lever 15 is located at the far right in FIGS. 1 and 16, and the operating lever 16 is at its highest position. Therefore, in this state, the lock pin 42 of the lock mechanism 40 is located in the wide part 38a of the elongated hole 38 and is pushed toward the shoji 7 by the receiving member 44, as shown in FIGS. 7 and 8. 9, the base 49 of the locking pin 42 is retracted from the actuating rod 14 to permit rotation of the handle 9, and the first hinge 50 is retracted from the engagement pin 5 as shown in solid line in FIG.
8 abuts on the engagement member 57 to connect the shoji 7 and the window frame 1, and the third hinge 70 has a spherical head 74 engaged in the engagement groove 73 and a cutout portion in FIG. 75 is located on the right side, connects the shoji 7 and the window frame 1, and prohibits the shoji 7 from opening inward.The stop mechanism 80 is located on each arm 81, 82, 83 as shown in FIG. are located in the same line, the slide arm 81 is separated from the stopper 85, and the pulling mechanism 10
0 is the rotor 1 as shown in FIGS. 22 and 24.
06 engages with the drawing protrusion 103 to bring the shoji 7 into close contact with the mating surface of the window frame 1, and the shoji 7
is locked to prevent it from opening.

When the handle 9 is rotated 90 degrees clockwise from the state shown in Fig. 1, the operating rod 14 rises by a pitch L of ₁ minute, the operating rod 15 moves the same amount to the left in Fig. 16, and the operating rod 16 moves by the same amount. amount decreases. Therefore, in this state, the lock mechanism 40 locks the lock pin 42.
is located in the wide part 38b of the elongated hole 38, but as long as the shoji 7 is closed, the base 49 of the lock pin 42 retreats from the operating rod 14 to allow rotation of the handle 9, and the first hinge 50 The engagement pin 58 is positioned as shown by the two-dot chain line in FIG. 9 and contacts the engagement member 57 to connect the shoji 7 and the window frame 1, and the third hinge 70 has the spherical head 74 cut out. Part 75
The stop mechanism 80 is in the state shown in FIG. 17, and the pulling mechanism 100 has the rotor 106 disengaged from the pulling protrusion 103, allowing the shoji 7 to open inward. Allows opening. Therefore, when the handle 9 is pulled inward in this state, the shoji 7 opens inward using the first and second hinges 50 and 60 as fulcrums.

When the shoji 7 is opened inward, the lock mechanism 4
0, the lock pin 42 comes off from the receiving member 44 and the base portion 49 enters the wide portion 38b of the elongated hole 38 due to the elastic force of the spring 43, thereby prohibiting movement of the operating rod 14. Therefore, when the shoji 7 is opened inward, rotation of the handle 9 is prohibited. When the shoji 7 is opened inward, the stop mechanism 80 is rotated counterclockwise around the first hinge 40 located at the right end in FIG. 17 together with the shoji 7 in the state shown in FIG. move. Further, in the third hinge 70, the engagement receiving member 71 and the engagement/disengagement member 72 are separated.

When the shoji 7 is closed from the inward-opening state, the lock pin 42 of the lock mechanism 40 again comes into contact with the receiving member 44, and its base 49 retreats from the operating rod 14, allowing the operating rod 14 to move.

If the handle 9 is further rotated 90 degrees clockwise in FIG. 1 without opening the shoji 7 inward or after closing the shoji 7 that opens inward, the operating rod 14
further rises by _one pitch L, the actuating rod 15 further moves the same amount to the left in FIG. 16, and the actuating rod 16 further descends by the same amount. Therefore, in this state, the lock mechanism 40 locks the lock pin 42.
is located in the wide part 38c of the elongated hole 38, but as long as the shoji 7 is closed, the base 49 of the lock pin 42 retreats from the operating rod 14 to allow rotation of the handle 9, and the first hinge 50 The engagement pin 58 is located as shown by the dotted line in FIG. 9, and is removed from the engagement member 57 to release the connection between the shoji 7 and the window frame 1, and the third hinge 70 is engaged with the spherical head 74. Concave groove 7
3 and is located to the left of the cutout 75 in FIG.
is in the state shown in FIG. 17, and the pulling mechanism 10
0, the rotor 106 comes off the drawing protrusion 103, allowing the window to open. Therefore, when the handle 9 is pulled inward in this state, the shoji 7 opens inward using the second and third hinges 60, 70 as fulcrums.

When the shoji 7 is opened inward, the lock mechanism 4
0, the lock pin 42 comes off from the receiving member 44 and the base 49 enters the wide part 38c of the elongated hole 38 due to the elastic force of the spring 43, prohibiting the movement of the operating rod 14 and the rotation of the handle 9.

When the shoji 7 is opened inward, the stop mechanism 80 causes the slide arms 81 to separate from the upper frame 2 as the shoji 7 tilts, so that each arm 81, 82, 83 is moved as shown in FIG. The slide arm 81 moves toward the stopper 85 and comes into contact with the stopper 85, thereby locking the shoji 7 from falling further inward. The maximum tilting angle of the shoji 7 when it is tilted inward is determined by the distance between the slide arm 81 and the stopper 85 in the state shown in FIG.
This can be changed by changing the side surface of 5 ₁ , 85 ₂ , 85 ₃ , and 85 ₄ that faces the slide arm 81 side.

In addition, this type of casement window that folds inward is generally
Since the fulcrum of the second hinge 60 protrudes further into the room than the shoji 7, the line connecting the fulcrums of the second and third hinges 60, 70 is the engagement receiving member 7 of the third hinge 70.

The third hinge 70 is tilted in a twisted state about a line connecting the fulcrums of the hinges 70, and an unreasonable force is particularly applied to the third hinge 70. To prevent this, the third hinge 70
The engagement receiving member 71 may be provided so that its engagement groove 73 coincides with a line connecting the supporting points of the second and third hinges 60 and 67; The direction does not match the moving direction of the engagement receiving member 71, and when the engagement receiving member 71 is moved, an unreasonable force is applied to the engagement receiving member 71 and the engagement/disengagement member 72.

In the window of the above-described embodiment, since the third hinge 70 engages the spherical head 74 with the engagement groove 73 having an arcuate cross section, the engagement groove 73 can be aligned with the moving direction of the operating rod 15. However, when the shoji 7 is turned inward, the third
No excessive force is applied to the hinge.

Effects of the Invention As described above, according to the present invention, band-shaped actuating rods connected to both vertical and lower stiles of the shoji are provided, and by engaging the actuating rods with the hinge and moving the actuating rods, the hinge can be moved. to cancel the concatenation function by
In addition, when the operating rod provided on the vertical stile that is not hinged to the window frame has at least two elongated holes with large diameter parts, and a lock pin is engaged with the elongated holes to open the window. Since the movement of the operating rod is prohibited by the lock pin, when the window is opened, the function of connecting the shoji and the window frame by the hinge that connects the shoji and the window frame can be released. Not only that, but the structure is simple.
