Description

[Detailed Description of the Invention] The present invention relates to an improvement of a rotating shaft device for a rotating fitting such as a rotating window.

Conventionally, this type of rotating shaft device includes a frame base on the frame side and a shoji base on the shoji side that can be engaged with each other via a shaft, and the shaft is movable up and down with the shaft base fixed to the upper end of the frame base. further includes an operating threaded rod that engages with the female thread of the shaft base and passes through a hole in the frame base, and by rotating the operating threaded rod, the shaft base and the shaft can be moved up and down. When the shaft is lowered, it engages with the corresponding hole in the shoji base and is set. However, with the conventional structure, it is not possible to confirm whether the shaft has been set correctly, and it is difficult to confirm whether the shaft has been set correctly or not. Since there is no mechanism to maintain the position, the shaft may be set with little engagement (engagement), and even if it is set correctly, the shaft may move upward or downward during use, causing less engagement. In the worst case scenario, the axis could come off.

Therefore, an object of the present invention is to provide a rotating shaft device for rotary fittings that can confirm whether the shaft is set correctly and can maintain the correctly set state.

Next, embodiments of the present invention will be described with reference to the drawings. The figure shows an example of a rotating shaft device according to the present invention, in which 1 is a frame, 2 is a shoji installed in the frame, and a frame base 3 is fixed to the frame 1 and corresponds to the frame base. A shoji base 4 is fixed to the shoji 2. Reference numeral 5 denotes a shaft serving as the center of this rotary shaft device, and a shaft base 6 made of a flat plate is fixed to the upper end of the shaft in a vertical relationship. A box 8 defining a space 7 inside is installed on the frame base 3, and a shaft base 6 is installed between flanges 8a on each side of the box 8 so as not to rotate. can be moved up and down. The space has a width in the vertical direction equal to or larger than the sum of the movement amount a of the shaft 5 (FIG. 2) and the thickness of the shaft base 6.
A hole 4a of a predetermined depth is formed in the shoji base 4 at a position corresponding to the shaft 5, and the shaft 5 can penetrate the hole 9 of the frame base 3 and engage with the hole 4a. . Reference numeral 10 denotes an operating threaded rod, which is parallel to the shaft 5, engages with an internal thread 11 provided on the shaft base 6, and its upper end is connected to the hole 8 of the box 8.
It is rotatably caulked to b, and the lower end is attached to the frame base 3.
It passes through the hole 12 and protrudes slightly. The threaded portion 10a of the operating threaded rod 10 has a length longer than the vertical direction of the space 7, and a groove 10b in which a screwdriver or the like is engaged is provided in the protruding portion at the lower end.

Further, as shown in the figure, this rotary shaft device includes a pin 13 fixed to a portion of the shaft base 6 on the opposite side of the operating threaded rod 10 with respect to the shaft 5 so as to project downwardly in parallel with the shaft 5, A through hole 14 is formed in the base 3 at a position corresponding to the pin 13, and the pin 13 passes through the hole 14 when the shaft base 6 is lowered. An annular groove 13a is formed at the lower end of the pin 13, and a retaining ring 15 is secured therein. As shown in FIG. 2, the pin 13 has a length such that when the shaft base 6 is lowered and comes into contact with the frame base 3, the pin 13 passes through the hole 14 in the frame base and the lower end portion of the pin is exposed from the frame base 3.

Since the rotating shaft device of the present invention is constructed as described above, when the shoji 2 is suspended in the frame 1, the shaft 5 is
Use a screwdriver or the like to turn the operating screw rod 10 so that it is not exposed from the frame base 3, hold the shoji 2 in a position where the shaft 5 matches the hole 4a of the shoji base 4, and turn the operating screw rod 10 to adjust the shaft. The base 6 is lowered to expose the lower end of the fixing pin 13 from the hole 14 in the frame base, and at the same time the shaft 5 is also lowered and engaged with the hole 4a in the shoji base, and by further turning the threaded rod, the shaft base 6 is moved to the frame base. 3, and the threaded rod 10 becomes unable to rotate. That is, when the operating screw rod 10 is turned until it stops rotating, the shaft 5 engages with the hole 4a of the shoji base, and the pin 13 is exposed from the bottom surface of the frame base 3, which indicates that the shaft is set correctly. is confirmed. Next, groove 1 on the exposed lower end of pin 13
If the retaining ring 15 is engaged with the frame base 3, even if the shaft 5 is subjected to an action that causes it to come out of the hole 4a of the shoji base, the retaining ring 15 will abut against the frame base 3 and the shaft 5 will not come out of the hole 4a. Prevented.

In the above embodiment, the retaining ring 15 is used as the retaining member, but a dowel pin may also be used as the retaining member, and in that case, the pin 13 has a pin instead of the groove 13a. A hole is provided. Alternatively, other locking members may be used.

As described above, according to the present invention, whether or not the shaft is set correctly can be confirmed by the exposure of the pin from the frame base, and the locking member attached to the pin prevents the shaft from coming out. This prevents this and allows the correctly set state to be maintained.
