This biases at least its outer periphery to protrude from the outer peripheries of the support body 10 and the traveling body a.

The traveling body a has a vertical bolt insertion hole 1 and a support body 1.
After inserting the bolt 21 into the vertical hole 16 of 0 from above,
The sliding door C is housed in a box-shaped rail b laid on the ceiling so as to be freely movable, and the sliding door C is suspended and supported by the lower half of a bolt 21 protruding from a rail groove 22.

The above rail b includes a top plate part b1, left and right side plate parts b2゜b2,
and left and right bottom plate portions b3 with a U-shaped cross section forming a rail groove 22 in the center. b3, which are laid vertically and horizontally on the ceiling slab by appropriate means, and the left and right bottom plate parts b3.
The edges of the decorative ceiling panels 23 and 23 are inserted and supported within the U-shape of b3.

That is, the device of the present invention accommodates the traveling body a in the box-shaped rail b through its longitudinal side end opening, and also loads the required number of bolts with the lower half of the bolt 21 protruding through the rail groove 22. It is suspended.

Among the wheels 4 of each device, a pair of wheels 4 corresponding to opposite sides where the running body a is located, for example, sides al and a5.
a and 4b are made to match the above rail groove 22,
The other two wheels 4c and 4d are connected to the left and right bottom plate portions b3. 1 to b3
The left and right bottom plate parts b3. 1 on board b3
Pair of wheels 4c and 4d and their corresponding traveling bodies a
The directions of the sides a51 to a7 are made parallel to the running direction of the sliding door C.

Further, the auxiliary wheels 8 are located at the left and right bottom plate portions b3. Two wheels are located slightly above b3, facing each other without contacting the upper surface thereof, and the wheels 11 are located slightly above the left and right bottom plate portions b3.
．． Each pair of wheels 11 above the pair of wheels 4c and 4d mounted on left and right side plate portions b2. Two of them are set in elastic contact with the inner surface of b2 (Figures 3 and 4).

Thus, one sliding door C is suspended at two places on the left and right ends of the upper surface of the door using two devices of the present invention. At the same time, a collar 25 made of synthetic resin is loosely fitted into the rail groove 22 of the bolt 21, and a lock nut 26 and a spring washer are inserted between the collar 25 and the label 24. 27 is installed.

The sliding door C suspended as described above is moved to a desired position by pushing or pulling it along the box-shaped rail b, and the desired partition is created or the partition is removed. In this case, the left and right bottom plate parts b 3 r b
The two rolling wheels 4ct4d mounted on g roll and rotate, and the left and right side plate portions b2. The four auxiliary rollers 11 that come into elastic contact with the inner surface of b2 roll and rotate, allowing the sliding door C to travel in a straight line easily and smoothly.

In addition, when the sliding door C is rotated to change the direction from one side A to the other B of the box-shaped rails b installed perpendicularly to each other, the left and right bottom plate portions b3 of one side A are ．． The rolling wheels 4c and 4d that were rolling and rotating on the other B are aligned with the rail grooves 22 of the other B, and the rolling wheels 4a and 4d that were aligned with the rail groove 22 of the one A are aligned with the left and right bottom plate portions b3 of the other B. Each pair of wheels 11 rolling and rotating on the left and right side plate portions b2. Two of them come into elastic contact with the inner surface of b2, roll and rotate, so that they continue to run lightly and smoothly (Fig. 4).

In this case, especially when the device passes through the intersection of the rail grooves 22, the bolt 21 rotates relative to the traveling body a, and also when all four wheels 4a to 4d are aligned with the rail grooves 22. , four auxiliary wheels 8 are mounted on the left and right bottom plate portions b3. By being mounted on b3 and rolling and rotating in the required direction, the direction of the sliding door C can be easily and smoothly changed.

Also, the wheels 4a and 4b are connected from the intersection of the rail grooves 22 to the left and right bottom plate portions b3 of the rail b of the other B. When riding on b3 and rolling and rotating, the orientation of the wheels 4a and 4b is the left and right bottom plate part b.

2. Each pair of wheels 11 parallel to wheel b2 and above the wheels 4a and 4b are connected to the left and right side plate portions b2. Since the elastic contact resistance of the rolling wheels 11 is at its minimum in the normal state where the rolling wheels 11 are in elastic contact with the inner surfaces of the left and right side plates b2. As it comes into contact with b2, the deviation is automatically corrected and the above-mentioned normal state is achieved, allowing smooth running in a predetermined direction.

As is clear from the above description, according to the device of the present invention, the required number of wheels are always placed on the bottom plate of the box-shaped rail, not only when the sliding door runs in a straight line but also when changing direction. A bolt that is inserted through the body and hangs the door rotates relative to the traveling body as the door changes direction, so that the direction of the wheel and the direction of the box rail are maintained in a predetermined relationship, In addition, the rolling wheels mounted above each corner of the regular octagonal prism-shaped running body so as to be horizontally rotatable rotate while coming into elastic contact with the left and right side plates of the box-shaped rail, so that the above-mentioned straight running and direction changes can be carried out easily and smoothly. Even large and heavy sliding doors can be moved and turned smoothly.

In addition, it has a simple configuration and can be manufactured at a relatively low cost.
Suspending the sliding door can also be done easily.
