Description

[Detailed Description of the Invention] This invention relates to a reversible window in which a shoji is attached in a reversible manner.

Traditionally, there are revolving windows that can be turned inside out, but in revolving windows, the shoji is pivoted to the window frame at the center of its width, so when the shoji is opened, half of the shoji is on the outside and the other half is on the inside. Not only does it look unsightly when viewed from the inside because it protrudes from the inside, but it is also impossible to install a windshield wall at the indoor end of the window frame that would prevent the shoji from rotating, so it is not possible to provide sufficient airtightness or watertightness. There was an unavoidable structural disadvantage in that it was not possible to ensure the

And the means to solve this shortcoming was first
No. 57-198209 was filed, but there were further problems with the invention that needed to be solved. That is, in the previous application, to explain it using the drawings of the embodiment of the present invention, the upper and lower links 1, 1 are fixed to one end of the window frame A so as to be able to swing outward in the horizontal direction. , A shoji B is pivotally supported at the tip of the link 1 so that it can be turned upside down at the center of the width, and an engagement piece 4 with the upper frame 2 and an engagement door wheel 5 with the lower frame 3 are attached to one side end of the shoji. It's a shoji B
When rotated around axis 6 at the tip of link 1,
One end of the shoji rotates largely to the outside of the window, and the other end of the shoji moves inside the window rather than the window frame when the shoji is opened and closed, as the engaging piece 4 and the engaging door roller 5 move along the upper frame 2 and lower frame 3. It has a structure that does not protrude. However, when the shoji is open, the shoji as a whole protrudes outward, making it susceptible to wind pressure and making it difficult to maintain the shoji at a constant opening angle.

Therefore, this idea was created so that the above-mentioned reversible window is configured so that the shoji stops opening and closing in stages while the shoji is being opened and closed, and the stopped state can be canceled by an extremely simple button operation. It is intended to.

Window frame A has upper and lower frames 2 and 3 and left and right vertical frames 7 and 8.
Windshield walls 9, 10, and 11 are provided respectively on the upper frame 2.
is provided with a groove-shaped guide strip 20 on which the engagement piece 4 of the shoji B is movably hooked, and the main rail 1 is provided on the lower frame 3 as a track for the vertically rotating main wheels 12 of the engagement door roller 5.

The sub rail 1 serves as a track for the horizontally rotating sub wheels 14.
5 is protrudingly provided, and furthermore, an upper stopper piece 17 is protrusively provided slightly above the sub-rail 15 to which the upper sliding piece 16 of the engaging door wheel 5 is joined. The upper stopper piece 17 is provided with several notches 18 at appropriate locations. By engaging the upper sliding piece 16 in this notch 18, the opening angle of the shoji B is maintained.

In this way, one end of the shoji B is movably engaged with the window frame A by the engagement piece 4 and the engagement door roller 5, but the other end is released from the window frame A and is free. However, the center part of the width is window frame A and upper and lower links 1 and 1.
The sliding shaft 19 of the link 1 is connected to the window frame A.
It is located at one end of the 21 is the open side vertical stile of the shoji,

Further, a hole 36 is provided in the center of the lower step piece 29, and stepped portions 37, 37 are formed on both sides of the hole 36, and further, auxiliary wheels 14, 14 are supported on both outer sides thereof. Reference numeral 66 denotes a side sliding piece that is joined to the rails 15 and 13.

The stopper 33 is an L-shaped piece consisting of both vertical and horizontal pieces 38 and 39, and the main plate 27 is attached to the back side of the vertical piece 38.
grooves 40, 40 that engage with the protrusions 35, 35 are provided, a through hole 41 for the engagement pin 34 is formed in the center as a long hole in the vertical direction, and the front edge 42 of the upper end surface is rounded. However, it is arranged in a virtual circle centered on the rotation axis 43 of the main plate 27. Also horizontal piece 39
A mounting base 44 for the upper sliding piece 16 is formed on the upper surface of the tip end thereof, and a support piece 45 that fits into the hole 36 of the main plate 27 so as to be vertically movable is provided on the lower surface thereof. And this stopper 33 is a leaf spring 4 bent in an angular shape.
6, the leaf spring 46 is adapted to be received by the stepped portions 37, 37 of the main plate 27.

The other parts of the stop device are attached to the end wall 52 of the stile 22 on the door end side, and consist of a case 47, a button 48, a back plate 49, and a coil spring 50. The case 47 is fixed to the end wall 52 with screws back to back with the shaft bearing piece 26, and the outer wall 54 is curved along an imaginary circle centered on the rotation axis 43 of the main plate 27.

Further, a protruding opening 51 for the button 48 and a storage pocket 53 for the coil spring 50 are provided at the upper end, a pair of left and right protrusions 55, 55 are formed on the back surface of the outer wall 54, and the back plate 49 is placed against the protrusions 55, 55. It is fixed. The button 48 has an inverted T-shape formed from a body 56 and legs 57 at the bottom, and is curved about the rotation axis 43. This button 48 also has its body 56 inside the case 47 and its outer wall 54.
and a back plate 49, and is biased upward by a coil spring 50, and the leg portion 57 is hooked to the lower end of the protrusion 55 by the elasticity of the spring 50.

In addition, a pulling tool 58 suitable for finger hooking is attached to the engagement side vertical stile 22 above the case 47, and an abutment piece 59 of the pulling tool 58 is attached to the window vertical frame 7, and the engagement between the two Shoji B is also prevented from coming off. Further, a puller 61 is integrally formed on the lower stile 60 of the shoji B.

Further, at one end of the lower frame 3, as shown in FIG.
A complementary piece 63 is provided in the deleted part 62.
is attached with screws 64. Further, 67 is a handle of the shoji screen, 68 is a lock, and 69 is a lock catch.

Since the inverted window of this invention is as described above, when the shoji B is closed as shown in FIG.
By holding the handle 67 at one end and moving the other end of the shoji toward the other end of the window frame A while pushing it outside through the lock 68, the shoji B can be opened as shown in FIG. Then, continue the movement until the third
As shown in the figure, the shoji B can be turned upside down. Moreover, the shoji B can be tightened to its original state by performing the reverse operation.

This series of operations involves movement of the rotating shaft 6 of the shoji and movement of the engagement piece 4 and the engagement door wheel 5, and if any of these movements is blocked, the opening/closing operation of the shoji B stops. Among them, the rotating shaft 6 moves on a circular orbit R centered on the swing axis 19 of the link 1, and the engagement door wheel 5 moves along the lower frame 3.

When the engaging door roller 5 moves along the lower frame 3,
The upper sliding piece 16 of the stopper 33 installed therein advances while being pressed under the upper stopper piece 17 of the lower frame 3, but the upper stopper piece 17 is provided with a notch 18 at an appropriate position. Therefore, when the sliding piece 16 reaches that point, the repulsive force of the bar 46 pushes the notch 18
rushes into it and gets caught in it. The movement of the engaging door roller 5 is prevented by this catch, and the shoji B
The opening/closing operation of the opening/closing operation is stopped and the constant opening angle is stably maintained. However, when the button 48 is pressed against the elasticity of the coil spring 50, the lower leg 57
In order to push down the stopper 33 against the elasticity of the leaf spring 46, the upper sliding piece 1 integrated with the stopper 33
6 is removed from the notch 18, and the locking state of the engaging door wheel 5 is released, so that the shoji B can be opened and closed again.

By the way, the engagement door wheel 5 has left and right sub wheels 14,1.
4 is in contact with the sub-rail 15, and the horizontal sliding piece 66 is joined to the main rail 13, and is sandwiched between both rails 13 and 15, so that it moves parallel to the lower frame 3. . The shoji B rotates about the rotating shaft 43 relative to the engaging door roller 5, and the position of the leg portion 57 of the button 48 relative to the stopper 33 changes due to this rotation. However, since both the front side edge 42 of the stopper 33 and the leg 57 of the button are shaped along a circle having the same center 43, even if the position changes, the leg 57 of the button 48 remains on the stopper 33. The upper sliding piece 16 can be removed from the notch 18 by operating the button 48 no matter which stop position the shoji B is at.

As explained above, this design attaches the upper and lower links to one end of the window frame so that they can swing outward in the horizontal direction, and the shoji can be turned over at the center of the width at the tip of the link. The shoji is pivoted on the shoji, and on one end of the shoji, an engaging piece that is movably hung on the upper frame in the longitudinal direction and an engaging door wheel that is movably hung on the lower frame in the longitudinal direction are attached. It can be opened by protruding only outside the window frame, or can be turned upside down, making it convenient for cleaning windows and other purposes.

In addition, the engaging door roller is sandwiched between the main rail and the sub-rail of the lower frame, so that the side sliding piece is connected to the main rail and the sub-wheel is connected to the sub-rail. When the shoji is opened, the upper sliding piece of the engaging door roller falls into the notch in the lower frame, so that the shoji is held at a certain angle. Since the shoji is held in an open state, it is possible to prevent the inconvenience of the shoji closing accidentally due to wind or the like.

In addition, one end of the shoji is always engaged with the window frame, but since a button is provided on the end surface of the engagement side to release the locking door wheel, it is easy to bend the hand to the button, especially when the shoji When the shoji is open, the engaging side end face faces toward the hand, which is extremely convenient for button operation, and has an extremely excellent effect of allowing the shoji to be opened and closed smoothly.
