Description

[Detailed Description of the Invention] This invention relates to a bearing for a rotating shaft of a rotating window in which a window frame and a sash shoji are assembled using, for example, an aluminum alloy shaped material.

To explain this invention with reference to the drawings, the window frame 11 and the shoji 3 have grooves 4 and 15 extending approximately in the center of their respective prospective surfaces.
will be established.

In a sash having a vertical rotation axis 1, such as a vertical rotation window, the axis length l of the upper rotation axis 1 is longer than the gap a between the window frame 11 and the shoji 3, and the sash is attached to the shoji upper stile 16. The rotating shaft 1 must be fully fitted into a bearing attached to the upper frame 17 of the window frame 11.

For this reason, the upper rotating shaft has conventionally been raised and lowered using a screw.

However, such a rotating shaft structure is complicated and expensive, and operation is troublesome.

In addition, the rotating shaft was not fully fitted into the bearing, and there was a risk that the shoji would fall over.

The present invention aims to solve these problems, and will be explained based on the drawings.

The upper rotating bearing to be attached to the upper frame 17 is divided into two parts at the part where the rotating shaft 1 is fitted, and the right fixed bearing part 7 is fixed in advance to the bearing mounting groove 4 of the upper frame 17 with screws 18.

A bearing groove 5 having a depth approximately equal to the diameter of the rotating shaft 1 fixed to the above-mentioned shoji upper stile 16 is formed in the fixed bearing portion 7, and this bearing groove 5 is opened. The end faces divided into two are used as retaining faces 6, 6, and a hole 19 is formed in each of them.
．． 19 will be provided.

This fixed bearing portion 7 is provided with small holes 20, 20 for attaching it to the upper frame 17 with screws 18.

On the other hand, in the rotating shoji 3, the rotating shaft 2 provided on the lower stile 22 is inserted into the bearing 23 provided on the lower sill of the window frame 11, and the shoji 3 is opened approximately 90 degrees as shown by the two-dot chain line 12. The upper rotating shaft 1 is inserted into the bearing groove 4, and the shoji 3 is erected approximately vertically.

This shoji 3 is in a 90° open state, and then the mounting bearing portion 10 is inserted into the bearing mounting groove 4 of the upper casing 17, and the end surface 9 of this mounting bearing portion 10 is engaged with the retaining surface 6 of the fixed bearing portion 7. Match.

In the case shown in FIGS. 2 to 4, the end surface 9 is a plane,
To this, a pin 21 . 21 is inserted in a fixed manner into a borehole 19 .

Then, the mounting bearing portion 10 in this state is fixed to the bearing mounting groove 4 of the window frame 11 with screws 13.

In order to easily operate a screwdriver for rotating the screw 13, a small hole 14 through which the screw 13 is inserted is positioned in the mounting bearing portion 10.

In this way, the mounting bearing part 10 is fixed to the window frame 17,
An upper vertical rotation axis 1 is supported.

The mounting bearing part 10 shown in FIG. 5 has a bearing surface 8 formed as a cylindrical surface 8, so that a portion 24 of this bearing surface 8 projects from the end surface 9.

Therefore, the protruding portion 24 is inserted into the bearing groove 5, and the pin 21 and the perforation 19 are not necessary.

The rotating bearing of the rotating window according to this invention consists of a fixed bearing part 7 and a mounting bearing part 1 made of metal or synthetic resin.
The rotating window shoji 3 can be easily attached to the window frame 17 due to the extremely simple structure of only 0.

Therefore, the cost can be kept low, and the shoji 3 can be easily removed and installed during repair.

Further, since the above-mentioned installation can be carried out while confirming that a sufficient length of the rotating shaft 1 is supported, there is no fear that the shoji will fall due to insufficient engagement.

Claims (1)

[Scope of utility model registration request] The bearing that fits the rotating shaft 1 of the rotating window shoji 3, which is rotatably supported by the window frame 11 around the upper and lower vertical rotating shafts 1 and 2, is divided into two parts, and one fixed bearing part 7 is attached to the window frame. The fixed bearing portion 7 is formed with a bearing groove 5 having a depth substantially the same as the diameter of the rotating shaft 1 and an engagement surface 6, and the bearing groove 5 and the engagement surface 6 are fixed in advance to the bearing groove 4 of the rotary shaft 1. The rotary window shoji 3 is attached to the mounting bearing part 10 so that the other mounting bearing part 10, on which the surface 8 and the end face 9 that engages with the engagement surface 6 are formed, is removably attached to the bearing mounting groove 4. is rotated by 90' with respect to the window frame 11
