Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a suspension traveling device for suspending and traveling a door or the like, and more specifically, enables stable traveling while maintaining surface contact even at corners and the like. It is related to the technology to be applied.

[Prior Art] Conventionally, in a suspension traveling device, as shown in FIG. 6, the mounting pieces 3 and 3 are placed inward from the left and right leg pieces 2 and 2 of the substantially channel-shaped rail main body 1. Extend over the entire length of the rail, and on the left and right mounting pieces 3, 3 the left and right rollers of the traveling body 5
The 6 and 6 were mounted so that they could roll freely.

[Problems to be solved by the invention] However, in such a configuration, the rollers 6,6 can be caused to travel in surface contact with the mounting pieces 3,3. It is difficult for the vehicle to swing and run stably, and especially when traveling in the corners, it tends to be swung out, and the traveling body 5 in axial form slides on the edges of the mounting pieces 3, 3 to cause resistance to travel. Will increase.

The present invention has been made in view of such a problem, and an object thereof is to eliminate side-to-side shake even at a corner portion while maintaining a surface contact state, and to always run stably and lightly. It is to provide a suspension traveling device that can be performed.

[Means for Solving the Problems] In the hanging traveling device of the present invention, the mounting pieces 3 and 3 are extended inward from the left and right leg pieces 2 and 2 of the substantially channel-shaped rail body 1 toward the inside. The taper surfaces 4, 4 that are inclined to the left and right as the mounting surfaces of the left and right installation pieces 3, 3 are separated from the leg piece 2
And the traveling block 8 on the shaft-shaped body 9 as the traveling body 5.
Is provided rotatably, and rollers 6, 6, 6, 6 are provided on the left and right sides of the traveling block 8 in the front and rear, and inside the rail main body 1 from the gap between the left and right mounting pieces 3, 3. Rollers 6,6,6,6 are rotatably provided around the horizontal axis X, around the left and right sides of the inserted traveling body 5, and the outer surfaces of the rollers 6,6,6,6 are tapered surfaces 4 , 4 to form a conical surface that matches the roller
It is characterized in that 6,6,6,6 are rotatably mounted on the tapered surfaces 4,4.

[Operation] As described above, the mounting surfaces of the left and right mounting pieces 3 and 3 are formed into the tapered surfaces 4 and 4 which incline downward as the distance from the leg piece 2 increases, and the traveling block is attached to the shaft-shaped body 9 as the traveling body 5. 8 is rotatably provided, and on the left and right sides of the traveling block 8,
Rollers 6, 6, 6, 6 rotatably provided around the horizontal axis X, X
The outer surface of the roller is formed into a conical surface that matches the tapered surface 4, and the roller 6 is rotatably mounted on the tapered surface 4, so that the traveling block 5 is mounted on the shaft-shaped body 9 as the traveling body 5.
Is rotatably provided, and the outer surfaces of the rollers 6, 6, 6, 6 rotatably provided around the horizontal axis X, X on the left and right sides of the traveling block 8 are mounted on the mounting pieces 3, 3. It is possible to run in a state of being in surface contact with the center of the rail and in the center of the width direction of the rail by the tapered surfaces 4, 4 of the mounting pieces 3, 3 and even if it is at the corner portion C of the rail 12, it is swung outward. It is designed to enable stable running without any problems.

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

Mounting pieces 3 and 3 extend inward from the left and right leg pieces 2 and 2 of the substantially channel-shaped rail main body 1 over the entire length of the rail. The mounting surfaces of the left and right mounting pieces 3 and 3 are formed into tapered surfaces 4 and 4 which are inclined downward as they are farther from the leg pieces 2. A gap d is formed between the left and right mounting pieces 3, 3. On the other hand, in the traveling tool 7, as shown in FIGS. 3 to 5, the shaft-shaped body 9 as the traveling body 5 is rotatably inserted into the traveling block 8 and retained by the traveling block 8, and the traveling block 8 has a horizontal shaft. A roller 6 is rotatably mounted on the horizontal shaft 10 via a bearing 11 to hold the roller 6 rotatably around a horizontal axis X. The outer surface of the roller 6 is formed as a conical surface that matches the tapered surface 4.
Then, the traveling block 8, the rollers 6, 6 and the traveling body 5 are inserted from the end of the rail 12 constructed as described above, and the roller 6 is rotatably mounted on the tapered surface 4. Then, a door body (not shown) is attached to the traveling body 5, and the traveling body 7 is suspended by traveling equipment 7 traveling along the rails 12 to open and close the door body.

In this way, the mounting surfaces of the left and right mounting pieces 3, 3 are formed into tapered surfaces 4, 4 that are inclined downward as they are farther from the leg pieces 2, and the traveling block 8 rotates on the shaft-shaped body 9 as the traveling body 5. It is provided freely, and on the left and right sides of the traveling block 8
Rollers 6, 6, 6, 6 rotatably provided around the horizontal axis X, X
The outer surface of the roller is formed into a conical surface that matches the tapered surface 4, and the roller 6 is rotatably mounted on the tapered surface 4, so that the left and right rollers 6 and 6 are in surface contact with the mounting pieces 3 and 3. In addition, the vehicle travels in a state of being centered at the center of the rail width direction by the tapered surfaces 4, 4 of the mounting pieces 3, 3 and is also swung outward at the corner C of the rail 12 shown in FIG. There is no such thing, and stable running is performed.

A pin 13 extends from the traveling block 8 and the pin 13
Further, the small roller 14 is rotatably held, and the small roller 14 is slidably contacted with the contact 15 hung from the rail body 1 to further prevent steadying.

[Advantages of the Invention] In summary, according to the present invention, the traveling block is rotatably provided on the shaft-shaped body as the traveling body, and the rollers are provided on the left and right sides of the traveling block. Rollers are provided on the left and right sides, and on the left and right sides of the running body inserted in the rail body through the gap between the left and right mounting pieces, and the rollers are rotatably provided around the horizontal axis. Therefore, smooth running is possible even at the corners of the rail, and the mounting pieces are extended inward from the left and right leg pieces of the substantially channel-shaped rail main body over the entire length of the rail to mount the left and right mounting pieces. The installation surface is formed as a tapered surface that inclines downward as it goes away from the leg piece, the outer surface of the roller is formed as a conical surface that matches the tapered surface, and the roller is rotatably mounted on the tapered surface. The traveling block rotates Even if it shakes and becomes difficult to orient properly in the traveling direction, the weight of the door body will be applied to the traveling block via the shaft-like body, and the traveling block will be corrected to correctly face in the traveling direction. This is an advantage that smooth and stable traveling can be performed even at the corner portion of the rail.
