A guide wheel support hole 10 for supporting the guide wheel 103 is provided in the central portion of the thin portions 101b.
1e is provided penetrating in the vertical direction.

The traveling wheel 102 includes a wheel body 102a and two wheel bodies 102a, as shown in detail in FIG.
Axle 102b connecting the wheels, the wheel body 102a, and the axle 1
02b and a sleeve-shaped dry bearing 102c interposed between the axle 102b and the axle 102b.
b, retaining washer 1 for retaining the dry bearing 102c
It consists of 02d. Sleeve type dry bearing 10
2c can reduce running friction without increasing the size of the wheel body 102a.

The traveling wheel 102 has a block portion 101.
Insert the axle 102b into the running wheel support hole 101d of
It is supported. The wheel body 102 a of the traveling wheel 102 has a thick portion 101 of the block portion 101 with a diameter.
It is formed to be larger than the vertical width of a and the outer periphery is the block portion 1
The thick portion 101a of No. 01 protrudes by S from both the upper end side and the lower end side.

As shown in detail in FIG. 4, the guide wheel 103 includes a wheel main body 103a, an axle 103b fixedly connected to the wheel main body 103a, and an intermediate portion between the axle 102b and the thin portion 101b of the block portion 101. Washer 10
3c and. The washer 103c includes the sleeve-shaped dry bearing 102c, the axle 102b and the block portion 10.
The thin bearing portion 101b and the wheel body 103a and the thin portion 101b of the lock portion 101 function as a thrust bearing.

The guide wheel 103 has a block portion 10
The axle 103b is inserted into the first guide wheel bearing hole 101e so as not to be pulled out and supported.

Therefore, the span La of the traveling wheel 102 is
It is shorter than the span Lb of the guide wheel 103.
Further, that is, the traveling wheels 102 are the traveling runner body 1
At 0, it is always located behind the guide wheel 103.

Further, in this embodiment, the runner base 42 of the upper runner 4 and the runner base 52 of the lower runner 5 have a common mounting structure to the traveling body 1.

That is, the cup cases 422 and 522 fixed by the screws 421 and 521 in the mounting groove 20 dug from the side end surface (the mouth end surface) 11 of the traveling body 1, and the cup case 42.
2, 522, and detachable holders 424, 524 screwed with bolts 423, 523.

The shaft member 43 of the upper runner 4 is formed in a bolt shape and is attached / detached to the holder 424 of the runner base 42.
Which is inserted in the holder and fixed to the attachment / detachment holder 424.
It is screwed to 5. Therefore, by the rotation of the shaft member 43,
The distance between the runner body 10 and the runner base 42 can be adjusted. The adjusted distance between the runner body 10 and the runner base 42 is set by the shaft member 43 provided on the runner base 42.
It is held by a set screw 426 that abuts against.

Further, the shaft member 53 of the lower runner 5 is formed in a shaft shape and is attached / detached to the holder 52 of the runner base 52.
4, a coil spring 525 is elastically mounted between the coil spring 525 and the detachable holder 424. Therefore, the shaft member 53
Can be in and out of the detachable holder 524, and the runner body 10
Are attracted to the runner base 52. However, the proximity of the runner main body 10 and the runner base 52 is restricted by the sleeve-shaped spacer 526 formed on the detachable holder 524 so as to be fitted to the shaft member 53.

According to this embodiment, the traveling mode is as shown in FIG. That is, as in the conventional example, the runner body 10 supports the load of the traveling body 1 on the upper side, and the traveling wheels 10
2 runs on the lower surface 302 of the rail 30. Further, on the lower side, the runner main body 10 is attracted to the runner base 52 by the coil spring 525 to prevent the traveling body 1 from swinging, and the traveling wheel 102 has the upper surface 301 (30) of the rail 30.
2) is surely traveled (state shown by a solid line).

At this time, the block portion 1 of the runner body 10
Due to the difference of S between 01 and the traveling wheel 102, traveling of the traveling wheel 102 is performed without any trouble. Therefore, the trouble due to the common structure of the runner body 10 on the upper side and the lower side does not occur. Therefore, by using the runner body 10 on both the upper side and the lower side, the manufacturing cost can be reduced and the mounting work can be facilitated. Also, on the lower side,
Since the coil spring 525 absorbs and damps backlash and the like, the runner body 1 travels stably and smoothly.

Further, in this embodiment, the runner body 10
In the traveling, the guide wheel 103 travels on the open end surface 305 of the rail 30. Therefore, this guide wheel 103
The traveling of the traveling body 1 is prevented even when the vehicle runs. Since the swinging of the traveling body 1 by the guide wheel 103 and the opening end surface 305 of the rail 30 has a rolling structure, the frictional resistance is low. Also, due to the swinging function of the traveling body 1,
The upper side and the lower side of the traveling body 1 do not share the function of supporting the load of the traveling body 1 and the function of supporting the traveling body 1, so that the traveling performance of the traveling body 1 does not differ. Further, when the runner main body 10 travels, as described above, the traveling of the guide wheels 103 for preventing the traveling body 1 from swinging precedes the traveling of the traveling wheels 102 that support the load of the traveling body 1, so that the curved portion of the rail 30 is curved. Stability of driving in etc.

Further, in this embodiment, when the traveling body 1 is lowered for some reason, the runner body 10 on the lower side is
The traveling wheel 102 of the rail is the lower surface 301 (302) of the rail 30.
Will be traveling (state shown by the chain double-dashed line in FIG. 6). Therefore, the traveling of the traveling body 1 is not hindered. Further, even when the traveling body 1 is lowered, the spacer 526 regulates the proximity limit of the runner body 10 and the runner base 52, so that the traveling body 1 does not collide with the rail 30.

FIG. 7 shows a second embodiment of the runner traveling structure according to the present invention.

In this embodiment, a ball bearing 102e is used for the bearing structure of the traveling wheel 102 of the runner body 10.

According to this embodiment, it is possible to deal with a case where the load of the traveling body 1 is large or a case where the traveling body 1 is traveling at a high speed.

8 to 10 show a third embodiment of the runner traveling structure according to the present invention.

In this embodiment, the runner base 42 of the upper runner 4 and the runner base 52 of the lower runner 5 are connected to the traveling body 1.
The thing fixed to the back surface 12 of is shown.

Further, in this embodiment, the cup cases 422 and 522 fixed to the mounting groove 20 dug in the back surface 12 are provided.
The nuts 427 and 527 are provided on the cup case 42.
It is possible to adjust the mounting positions of the attachment / detachment holders 424 and 524 with respect to 2,522.

According to this embodiment, the surface of the traveling body 1 can be easily flattened.

As described above, in addition to the illustrated embodiment, the runner bases 42 and 52 and the shaft members 43 and 53 may be other embodiments.

Furthermore, it is possible to adopt an embodiment of a structure other than the hanging door, for example, a structure in which the load of the traveling body is supported on the lower side and the shake is prevented on the upper side.

[0043]

As described above, the runner traveling structure according to the present invention has, in common with each claim, the runner body having both traveling wheels for supporting the load of the traveling body and guide wheels for supporting the traveling body. Therefore, there is no difference in running performance between the upper side and the lower side, which has the effect of smooth running.

Further, in common with each claim, since the swinging structure of the traveling body is the rolling structure by the guide wheels or the like, there is an effect that the friction resistance is reduced and the traveling body travels more smoothly.

Further, only in claim 2, since the traveling of the guide wheels for preventing the traveling body from swinging precedes the traveling of the traveling wheels which bear the load of the traveling body, the traveling on the curved portion of the rail is stabilized. There is.
