2. Description of the Related Art In a conventional protruding window, as shown in FIG. 7, about 2 to 3 hinges 23 are attached between an upper frame 21 and an upper frame 22, and the hinge 23 is attached to a rotary shaft of a shoji 24. Since the sliding door 24 has such a form, the sliding angle of the sliding door 24 is at most about 60 degrees, and it is structurally impossible to rotate it to a door opening angle larger than that. Therefore, the opening angle of the sliding door is narrow. Also, since the hinge is attached, the usability and workability are poor, and a plastic block is screwed to the left and right vertical frames to stop the shoji 24 from moving in the left and right directions. Not only the screw fixing work is required, but the block is annoying because it can be seen from the inside and outside of the room, and when the sash is a colored product, it is difficult to match the color of the sash and the color of the block, To harmonize the colors Always been a tedious task.

[0003]

The present invention replaces the conventional hinge mechanism as a rotary shaft, is simple in assembly and is structurally robust, and has a large door opening angle of about 90 degrees. It is intended to obtain a rotary shaft structure of an ejector window which is improved in usability and workability, and which is excellent in appearance without using the conventional block. is there.

Operation and Embodiments The structure of one embodiment of the present invention will be described below with reference to FIGS. 1 and 2. On the surface plate 2 facing the outdoor side of the upper frame 1, the surface plate 2 is provided at a predetermined position above the surface plate 2.
Structural frame 3 formed integrally with and orthogonal to the room direction
Is provided, and a support arm 4 of a predetermined length that projects in the room direction is integrally formed at the lower end portion, and a required large space 5 formed by the structural frame 3 is provided above the support arm 4. ing. A columnar body 6 rotatably and slidably supported is formed on the support arm 4 at the tip, and an arm body 7 having a predetermined length from the columnar body 6 is provided. From the tip of the arm body 7 to the arm An arcuate upper body 8a having the length of the body 7 as the radius of the outer peripheral surface is formed approximately 1/4 round, and further, a straight intermediate body 8b of a certain length which is continuously formed in the tangential direction of the arcuate body 8a. A hook body 8 consisting of an arcuate lower body 8c that has a shape and extends toward the surface plate 2 side of the upper frame 1 is formed in series, and a shoji body frame 9 parallel to the surface plate 2 is integrally molded from the hook body 8. ing.

The hook body 8 of the shoji body frame 9 is suspended from the support arm 4 of the upper frame 1, whereby the columnar body 6 at the tip of the arm body 7 is rotatably supported by the support arm 4. There is.
An adapter 11 having an arcuate pressure receiving surface 10 slidably contacting and supporting the outer surface of the upper body 8a is provided in the space 5 outside the arcuate upper body 8a of the hook body 8 such as a screw on the structural frame 3. It is fixed by a stator 12 so that it can be attached and removed freely.

The adapter 11 is attached to the structural frame 3 as described above.
When attached to, the tip of the support arm 4 and the adapter 1
The distance D between the pressure receiving surface 10 and the lower end of the pressure receiving surface 10 is smaller than the length L between the lower end point of the outer peripheral surface of the cylindrical body 6 and the outer peripheral surface of the arm body 7,
Also, the distance δ between the center of the cylinder 6 and the lower surface of the support arm 4
Is set to be smaller than the radius γ from the center of the cylindrical body 6 to the inner peripheral surface of the upper body 8a of the hook body 8.

Further, the adapter 11 is provided with a hanging frame 13 which is integrally formed so as to project downward from a predetermined position.
An anti-vibration piece 14 is fixed to the hanging frame 13 at a position corresponding to both ends of the shoji body frame 9 by a stator 15 such as a screw, thereby preventing the shoji body frame 9 from moving in the left-right direction. It is done like this.

Next, the operation will be described with reference to FIGS. Each of the drawings is a schematic view in which the operation of the main part is described according to the progress of the rotation of the shoji body frame 9 from the closed state to the opened state of approximately 90 degrees, and when the shoji body frame 9 is closed. It is easily understood from FIGS. 3 and 4 showing that the shoji main body frame 9 is rotated about the opening angle of about 90 degrees around the cylindrical body 6 as a center of rotation in order. As described above, the shoji main body frame 9 is engaged with the upper frame 1 so as not to deviate, and even when the shoji main body frame 9 shown in FIG. 9 is engaged with the upper frame 1 so as not to deviate. That is, the distance D between the tip of the support arm 4 and the lower end of the pressure receiving surface 10 of the adapter 11 is smaller than the length L between the lower end point of the outer peripheral surface of the cylindrical body 6 and the outer peripheral surface of the arm body 7. Therefore, the hook body 8 of the shoji body frame 9 cannot be detached from the upper frame 1 by any means unless the adapter 11 is removed.

The distance δ between the center of the cylinder 6 and the lower surface of the support arm 4 is from the center of the cylinder 6 to the hook body 8.
Since it is set to be smaller than the radius γ to the inner peripheral surface of the upper body 8a, the shoji main body frame 9 can rotate 90 degrees. Further, the vibration blocking piece 14 can prevent the shoji body frame 9 from shifting in the left-right direction (the width direction of the shoji).

[0011]

As is apparent from the above description, according to the present invention, the hook body rotatably slidably supported and the shoji body frame are integrally molded as an aluminum mold member, and the shoji body frame is constructed by connecting the hook body. It has a simple structure that only suspends it from the support arm of the upper frame and attaches an adapter. It is easy to assemble and is structurally robust. The door opening angle is about 90 degrees and a large rotation angle can be obtained. The rotation axis structure of the ejector window is extremely safe and has a very good appearance, while dramatically improving usability and workability, such as preventing the frame from moving in the left-right direction.
