Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rotary for changing the running direction of a movable wall that can run guided by rails installed on the ceiling, and particularly for use with large movable walls, it has excellent robustness and ease of assembly. This relates to a rotary for movable walls that pursues improved accuracy.

Conventional moving walls have main wheels 3, 3, . . . that roll on rails 1, 1 laid on the ceiling, as shown in Fig. The movable wall 5 is attached and the movable wall 5 is moved using the rail 1 as a guide, and the room can be partitioned freely. It is also possible to run on rails, greatly increasing the degree of freedom of movement, but if the rails 1 and 1 are only fixed, the nature of the moving wall is that the range of movement is determined by the rails laid. Above all, the degree of freedom of movement cannot be increased beyond a certain point.

Therefore, as shown in FIG. 2, a rotatable rotary 9 with a rotating straight rail 7 and a rotating curved rail 8 fixedly installed is provided at the intersection of the fixed rails 6a, 6 and 6c, 6d that intersect on the ceiling surface. In the state shown in Fig. 2, the errand 2 can be fixed by moving it linearly from the fixed rail 6a through the rotating linear rail 7 to the fixed rail 6b, or by rotating the rotary 9 450 times clockwise from the state shown in Fig. 2. By moving the object on the rail 6b via the rotating curved rail 8 to the fixed rail 6d and turning the movable wall at right angles, the movable wall can be freely transported. As a rotary for moving walls that is already known, a rail body having both end edges formed in an arc shape with the same diameter is attached to a rotating plate, and each of the edges is positioned on the same circumference. hand,
A hanger rail body is formed, and each end edge of three or more hanger rails fixed to the ceiling surface is formed into a concave arc shape having the same diameter as the rail body edge, and each hanger rail end edge is connected to the hanger. Positioned on the same circumference as the periphery of the rail body,
The rotary plate is attached to the fixed metal fitting fixed to the ceiling surface via a sliding body, and the rotary plate is made to rotate freely by a stopper provided on the fixed metal fitting, and both ends of the rail body are rotated intermittently by the stopper provided on the fixed metal fitting. Rotary connection mechanism for hanger rails that can freely communicate with different ends of hanger rails (Special Publication Publication No. 50-325)
40), but in this case, only a sliding body is interposed between the fixing fitting and the rotating plate, so 1
When a large moving wall weighing up to 2 tons transfers from a fixed rail to a rail on a rotating plate, the rotating plate is tilted due to the space between the sliding body, the fixed metal fittings, and the rotating plate, causing an impact on the moving wall. In addition, due to the lack of a means of centering between the rotating plate and the fixed metal fittings, as well as the ceiling, the gap between the fixed rail and the rail on the rotating plate is no longer symmetrical, and this gap This caused a large impact on the moving wall that was being climbed over. The present invention aims to eliminate the disadvantages inherent in the conventional movable wall rotary as described above.A rotating rail is fixed to a rotary body suspended from the ceiling, and the rotary body runs on the rotating rail by rotation of the rotary body. In a rotary for a movable wall that is designed to change the running direction of the movable wall, a fixed guide plate is fixed to the rotary mounting board fixed to the ceiling using a plurality of mounting adjustment hanging tools, and the fixed guide plate allows the above-mentioned A rotary main body is guided and supported, a thrust bearing is interposed between the rotary main body and the fixed guide plate, and a bearing is interposed between a drive shaft fixed to the rotary main body and the rotary mounting board. The present invention provides a rotary for a movable wall which is characterized by the following mechanism.

Next, embodiments of the present invention will be described in detail with reference to the accompanying drawings starting from FIG.

In these figures, a plurality of mounting holes 13 are drilled radially in a rotary mounting board 12 that is fixed by means such as welding to a building structural material that constitutes a part of the ceiling and is reinforced by channels 11. , -13, . . . are inserted and fixed by nuts 14, 14. Adjustment hanging bolts 15, 15, . A fixed guide plate 18 is tightened and fixed between the attached nut 17. A rotary straight rail 20 and a rotary curved rail 21, similar to those shown in FIG. Bolts 22 at the four corners on the top surface of the plate 18,
L-shaped angles 23, 23 fixed by 22,...
, . . . The guide runners 26, 26, . The ball bearing 29 is mounted on the guide plane 27 so as to be able to roll on the guide plane 27.The ball bearing 29 is fitted on the drive shaft 28 fixed on the axis of the rotary body 19. It is fitted into a mounting groove 30 recessed in the center of the rotary mounting board 12 and is gripped and fixed by a cap 31 screwed to the rotary mounting board 12. Core 1
The self-aligning thrust roller bearings 35 and 34 are fitted in annular grooves 33 and 32 recessed around the center of the rotary body 19.
By tightening a nut 40 screwed onto the threaded portion 39 of the drive shaft 28, the nuts 40 are sandwiched on both sides by an annular groove 38 formed on the lower surface of the presser plate 37 fitted to the drive shaft 28, centering on the shaft core 1. Thrust roller bearings 35 and 34 are sandwiched between the rotary body 19 and the holding plate 37, with the fixed guide plate 18 sandwiched therebetween. Further, a gap 42 is interposed between the drive shaft 28 and a push-in hole 41 formed in the axis of the fixed guide plate 18. Next, the operation of the above-mentioned embodiment will be explained. When a hanging wheel having a movable wall hanging thereon passes over the rotary straight rail 20 or the rotary curved rail 21, the load of the movable wall applied to each rail is transferred to the rotary main body 19. , L-shaped angles 23, 23 and guide runner 26, is applied to the fixed guide plate 18, and is further transmitted to the rotary mounting board 12 via the hanging bolt 15.

Furthermore, when the drive shaft 28 is rotated by a motor (not shown) provided on the rotary mounting board 12, the rotary main body 19 and the presser plate 37, which are fixed to the drive shaft 28, rotate together with the drive shaft 28. The rotary main body 19 and presser plate 3
The fixed guide plate 18 held between the thrust roller bearings 35 and 34 held by the fixed guide plate 7 does not rotate because it is fixed to the rotary mounting board 12 by the hanging bolt 15 and comes into contact with the guide plane 27 of the fixed guide plate 18. A guide runner 26 rolls on the guide plane 27. When assembling this rotary, the drive shaft 28 is inserted into the bearing 29 fitted coaxially with the axis 1 of the rotary mounting board 12, and the drive shaft 2
Rotary main body 19 and presser plate 37 attached concentrically to 8
During this period, the thrust roller bearing 3 is inserted through the fixed guide plate 18.
By tightening 5 and 34, the rotary mounting board 12
Attach the rotary main body 19 and fixed guide plate 18 so that their centers are aligned with the center of By adjusting the
The installation height of the fixed guide plate 18 is adjusted, and the heights of the rotating linear rail 20 and rotating curved rail 21 guided thereby are made equal to the height of the fixed rail laid on the ceiling. FIG. 11 shows a rotary in which the bearing portion of the rotary shown in FIG. 3 has been modified to reduce the size of the rotary as a whole.

In this case, compared to the rotary shown in Figure 3, the thrust bearing 3
The annular grooves 3', 33'' that receive the bearings 3C, 35'' have a small diameter, and the thrust bearings 3C, 35'' are directly attached to the drive shaft 28. In this way, the small thrust bearings 34'' as shown in FIG. , 35'', the outer diameter of the rotary can be reduced to about two-thirds.As described above, the present invention allows the fixed guide plate to be mounted on the rotary using a plurality of mounting adjustment hanging tools. Since it is fixed to the board,
Even when hanging a large moving wall with a large weight, the fixed guide plate will not bend, and this installation adjustment hanging tool allows you to adjust the height of rotating rails such as rotating linear rails and rotating curved rails to the ceiling. The height of the fixed rail can be adjusted with high precision, and when the hanging wheel moves between the rotating rail and the fixed rail, the moving wall will not receive any impact due to the difference in height between the two rails or the deflection of the rotating rail. Moreover, since a bearing is interposed between the drive shaft and the rotary mounting board, and a thrust bearing is interposed between the rotary body and the fixed guide plate, the rotary can be mounted around the drive shaft. As a result of being able to correctly adjust the cores of the board, rotary body, and fixed guide plate, it is possible to improve the accuracy of the gap at the joint between the fixed rail and rotating rail, reducing the impact that is applied to the moving wall when traveling through the joint. When applied to a rotary with a large movable wall, it exhibits a great effect in terms of buffering performance.
