Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a double bearing for supporting a winding suspension shaft provided for opening and closing the lining under the ceiling of a greenhouse, for example.

Conventionally, this type of double bearing was attached to the lower end of a wire hanging from the ceiling of a greenhouse, the lower hook part was engaged with the fixed shaft, and the winding hanging shaft was hooked into the cutout hole of the main body to support it. I have to.

However, with these double bearings, the open part of the notch hole is always open, so if the winding hanging shaft that rotates in the long hole is bent or bent, the hanging shaft will move vertically, horizontally, or vertically within the notched hole. It sometimes moved loosely and fell out of the opening of the notch hole in the main body.

Therefore, the present invention aims to provide a double bearing that can completely prevent the winding suspension ring from falling off.

An embodiment of the present invention will be described below in detail with reference to the drawings.

In the drawing, reference numeral 1 denotes a double bearing, which includes a main body 3 for supporting a winding hanging shaft 2 and a fixed shaft 4 for supporting a lining receiving wire.
The hook for engaging the winding shaft 2 is composed of a piece 5 and a blocking piece 6 for preventing the winding hanging shaft 2 from falling off.

The main body 3 is formed by bending a plate 7 having a shape as shown in FIG. 3, which is punched out from a metal plate.

The main body 3 is formed in a hook shape with a cutout hole 9 having an open portion 8 facing diagonally upward in the center, and the winding hanging shaft 2 is hooked into the cutout hole 9.

Also, in the upper part of the main body 3, there is a through hole 10 for connecting to other objects.
and the connecting portion 1 that is secured by the bolt 11 inserted into the through hole 10.
2.

- A support shaft 13 is attached to the lower part of the notch hole 9 of the old main body 3, and the support shaft 13 has hook pieces 5, 5 formed by punching out a metal plate.
are rotatably fitted.

Furthermore, pins 1 are provided on both sides of the lower part of the notch hole 9 of the main body 3, respectively.
A support body 15.15 consisting of a roller is pivotally mounted via a shaft 4.14, and a part of the outer periphery of the support body 15,15 protrudes into the notch hole 9.

The hook piece 5 has a hook portion 16 at its lower end that can engage with the fixed shaft 4.

The blocking piece 6 is made of a metal plate and has projecting pieces 17°17 on both sides of one end.
The projecting pieces 17, 17 are fitted into the through holes 19° 19 formed in the free ends 18, 18 of the main body 3, and rotated around the projecting pieces 17, 17 to open the open part 8. It is designed so that it can be opened and closed.

A stopper 20.20 that can engage with the outer surface of the blocking piece 6 is protrudingly provided on the inner surface of the free end portions 18, 18, so that the blocking piece 6 holds the open portion 8 in the closed position. It is configured to prevent outward rotation.

Also, on the outer sides of the stoppers 20, 20 there are slopes 21 and 21.
is formed, and when the blocking piece 6 rotates from the outside to the inside, the free ends 18, 18 are spread out to both sides, and the stopper 20.20
It is formed so that it can pass through.

When the suspension bearing 2 configured as described above is used, it is shown in FIG.
As shown in FIG. 5, the lower end of the rod-shaped hanger 23 suspended from the ceiling of the greenhouse 22 is connected to the bolt 11 of the connecting part 12, and the hook part 16 of the hook part 5 is connected to the inner lining 22.
The hanging bearing 1 is held in tension by the hanging tool 23 and the fixed shaft 4 by hooking it onto the fixed shaft 4 for supporting the receiving wire 25 of No. 4.

Then, with the free ends 18, 18 pushed apart and the blocking piece 6 rotated outward, the winding hanging shaft 2 is hooked into the notch hole 9 of the main body 3, and the winding hanging shaft 2 is connected to the support 15. , 15 will bear the burden.

Then, when the blocking piece 6 is rotated inward, the blocking piece 6 presses the stopper 20 outward against the elasticity of the free ends 18, 18, and after passing the stopper 20, the stopper 20 returns to shut off. Engaged with the outer surface of the piece 6, the opening 8 is closed.

When the winding hanging shaft 2 is rotated in this set state, the shaft is supported by the supports 15, 15 and rotates smoothly.

At this time, even if the winding hanging shaft 2 is bent or bent and moves vertically and horizontally within the cutout hole 9, the blocking piece 6 restricts the shaft from moving outward from the opening 8. The winding hanging shaft 2 does not deviate from the notch hole 9.

In the above description, two supports 15 are used, but the number may be three, or three or more.

Further, the pin 14 of the support body 15 may be used as the shaft of the hook piece 5.

The members constituting the main body 3 are not limited to one plate formed by press molding, but may be formed from two plates, or may be formed from a block-shaped material.

As described above, according to the hanging bearing of the present invention, the winding hanging shaft and the fixed shaft can be attached with an extremely simple operation of just hooking them.Furthermore, the hanging shaft for winding can be prevented from falling off during use. This can be prevented by

Moreover, the opening of the cutout hole can be opened and closed by the blocking piece, and the winding suspension shaft can be easily attached and detached while the suspension bearing is attached.
