It relates to a vehicle in which a plurality of wheels are used on the top and bottom, and the running rail is a vehicle in which the bottom of the wheel is tilted inward and has a triangular cross section.

A running rail with a wheel bottom was laid toward the ceiling, and the wheels of a fishing wheel, which rotates vertically like the wheels of a cart, were placed on the wheel bottom, and the fishing shaft was suspended from the chassis between the sliding grooves. A vertical wheel fishing wheel device in which a fishing wheel is installed in a traveling rail and the upper end surface of a panel is connected to a fishing shaft, and a horizontal wheel fishing wheel device in which a horizontal wheel is directly attached to the fishing shaft and the panel is connected to the horizontal wheel. In this case, the wheel bottoms of the running rails are inclined inward to have a triangular cross section as described above.

ネルを移動させるに必要である。 Generally speaking, these fishing wheel devices (including the present invention) have the following requirements. That is, stable movement and running can be obtained and direction changes can be easily performed. Orientation is necessary to move panels to create new or eliminate partitions.

いものにおいては、水平車輪に加わる力が大きい
ので、バランスを失して、走行レール内で衝突を
起し易い。 One drawback of conventional horizontal wheel fishing wheel devices is that it is difficult to balance the fishing wheel when moving straight in the direction of the running rail. That is, the lower surface of the horizontal wheel is supported at one point by the triangular inclined wheel bottom and rotated, but it tends to swing from side to side, causing the support to be biased and the running to be accompanied by meandering. When the weight of the panel is heavy and the panel length is high, the force applied to the horizontal wheels is large, making it easy to lose balance and cause a collision within the running rail.

又、前記の考案例のように、ラジアル玉軸受を
水平車輪に用いたものは、重量パネルに対して弱
く、安定性に乏しい。 Further, as in the above-mentioned example of the invention, those using radial ball bearings for horizontal wheels are weak against heavy panels and lack stability.

は、難儀なことであり、水平車輪にとつて非常な
無理を強うることになる。 The most important point is that the fishing cart does not move easily at the intersection of the traveling rails. This also applies to fishing wheels with four horizontal wheels in which the bottoms of the wheels protrude from each other on the left and right, as well as fishing carts with two horizontal wheels in which the bottoms of the wheels protrude vertically in alternating directions as in the above-mentioned example. But it's the same. First, in a fishing wheel with horizontal wheels, the wheel bottom is cut due to the crossing of the sliding grooves at the intersection of the traveling rails, and the distance between the wheel bottoms is widened, whereas in the case of the fishing wheel with vertical wheels, the gap between the sliding grooves is widened. This can be done by descending the sloping bottom of the wheel without dropping the wheel. This is an advantage. However, it is difficult to push the horizontal wheels of a fishing cart that has descended slightly downward at an intersection toward the direction change side, lifting them slightly upwards, and it is extremely difficult for horizontal wheels to do so. will be forced to do so.

殊に前記二層水平車輪の釣車においては、走行

り、走行が乱れるという欠点があつた（図面第７
図参照）。 In particular, in the above-mentioned two-layer horizontal wheel fishing wheel, the wheel bottoms of the running rails are protrusions that face each other in an alternating manner. A bottom discontinuity occurs. As a result, there was a drawback that the horizontal wheels at intersections were uneven and the running was disrupted (see Figure 7 in the drawing).
(see figure).

A fishing wheel in which three horizontal wheels such as compound thrust ball bearings each having a dust cover on the upper surface are rotatably fixed to a vertical fishing shaft via a spacer, and an opening facing downward in vertical section. The U-shaped oblong member is made to protrude inwardly at right angles from both open ends of the U-shape, leaving a sliding groove in the center of the tip, to form an oblong support base.
A wheel bottom having a triangular cross section that slopes inward at right angles inward at the left and right sides of the U-shape,
It is a pair of protruding running rails that are vertically opposed to each other and are approximately the same length as the protruding length of the supporting pedestal, and a flat plate-like small part that has the same shape as the shape of the supporting pedestal at the intersection at the intersection of the running rails. The support piece is of the same size and is attached to a support base and has a tapered slope in the direction in which the horizontal wheel moves when attached, and is attached to a running rail laid vertically and horizontally in the direction of the ceiling. In a fishing wheel with a suspended panel, in the straight direction, the fishing wheel moves with the upper two horizontal wheels supported by the wheel bottoms of the running rail and rotating, while the lower horizontal wheel is lifted off the support base of the running rail. However, when moving through an intersection, the lower horizontal wheel is supported by the lower surface of the support piece fixed to the upper surface of the support base, which is in contact with the running rail at the intersection, and the upper two horizontal wheels are A fishing wheel device with three-layer horizontal wheels, characterized in that the sloping surface of the bottom of the wheel is not lowered but slightly floated, the surface slides or rotates as the surface moves, and the direction is changed.
