Description

[Detailed description of the invention] This invention is a rotating window in which the horizontal shafts protruding from the left and right vertical frames of the shoji or the vertical shafts protruding from the top and bottom frames are rotatably supported by bearings installed in the window frame. This invention relates to a shaft support device.

The rotary window shaft support device of the present invention is configured to prevent the shaft of the shoji from separating from the bearing of the window frame when the shoji is opened due to wind pressure. The details of this proposal will be explained with reference to this document.

In Figure 1, the window frame 1 consists of left and right vertical frames 2 and 3 and upper and lower frames 4 and 5, and the shoji 6 consists of left and right vertical frames 7 and 8 and upper and lower frames 9 and 10. , the left and right vertical frames 7 and 8 of the shoji 6
The middle part is rotatably supported by the main shaft support devices A and A between the left and right vertical frames 2 and 3 of the window frame 1, respectively.

The proposed shaft support device mainly consists of a shaft 11 and a bearing 12,
As shown in the second and third figures, the shaft 11 is vertically protruded on a rectangular base plate 13, and has an annular groove 14 formed on the circumferential surface of the tip of the shaft. Stiles 7,
By fixing it to the middle part of the prospective face of frame 8 with screws 15, it protrudes perpendicularly from the prospective face of the frame.

The bearing 12 consists of a bearing main body 16 and a shaft retainer 17, and the bearing main body 16 has a rectangular substrate 1B as shown in Figure 2.3.5.
A block protruding from above, on which a substrate 18 is attached.
A substantially U-shaped bearing hole 19 with an upward opening 19' is formed when viewed from the front, and the substrate 18 is fixed to the side of the shoji in the vertical frames 2 and 3 of the window frame with screws 20... As a result, it faces the axis 11 of the shoji.

In this bearing hole 19, the shaft 11 of the shoji screen is rotatably supported.

21 is a bearing metal attached to the inner surface of the bearing hole 19.

The shaft presser 17 is the second. 3. 4 As shown in the figure, this block is formed at one end of a rectangular base plate 22 and has a pin-shaped protrusion 23 protruding from its tip, and this shaft retainer 17 is inserted into the bearing hole 19 from the opening 19'. With the protrusion 23 engaged in the annular groove 14 of the shaft 11, the base plate 22 is fixed onto the base plate 18 of the bearing body using the screws 20 and 20.

With the above configuration, the shaft holder 17 closes the opening 19' of the bearing hole 19 to prevent the shaft 11 from separating upward from the bearing 12, and the protrusion 23 closes the annular groove 19 of the shaft 11.
This prevents the shaft 11 from disengaging from the bearing 12 in the axial direction.

In the other embodiment shown in FIG. 6, a projection 23a is also provided on the bearing body 16, and the projection 23a is engaged with the annular groove 14 of the shaft 11, and the other structure is substantially the same as that of the above example. This is an example.

If necessary, an example in which the protrusion 23 is removed from the above example may also be implemented.

The projection is not limited to a pin shape, but may be of any shape as long as it does not interfere with the rotation of the shaft 11 and prevents the shaft 11 from being pulled out in the axial direction.

According to the rotary window shaft support device of this invention, the protrusion on the side of the bearing can engage with the annular groove of the shaft and prevent the shaft from disengaging in the axial direction, thereby preventing wind pressure when the shoji is opened. Even if the shoji is agitated, the shaft of the shoji can be sufficiently prevented from coming out from the bearing of the window frame.
This makes it possible to provide a revolving window that is extremely safe to use.
