Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a device that can suspend and travel movable partition panels.

(Prior art) The panel hanging/travel device for movable partitions does not simply move in a straight line, but also runs along rails crossed at right angles in order to change the direction of the suspended panels. It is composed of Figure 12 shows a conventionally used suspension traveling device, in which rollers (B) are supported by shafts on each side of the chassis (A), and a suspension shaft (C) is mounted in the center of the chassis (A). Connected facing downwards. The hanging shaft (c) is fixed to the upper end of the panel to suspend the panel, but one panel has a hanging shaft (c) fixed to the upper end of both left and right ends.
C) It is suspended by (C), and the hanging shaft (C) is connected to the chassis (A) as described above. Therefore, the chassis (
If (b) travels and moves along the rails, the panels also move, partitioning a predetermined space, or conversely being stored in a predetermined location. By the way, if the chassis (A) only travels and moves along straight rails, it is sufficient to simply attach the rollers (B) to the sides of the chassis, but if the chassis (A) only runs and moves along straight rails, it is sufficient to attach rollers (B) to the sides of the chassis. To change direction, the hanging shaft (c) must cross over the movement groove (d) along which it moves. This moving groove (
As shown in Fig. 12 above, it is impossible to pass through the ball (N) with only the rollers (B) attached to the sides of the vehicle, so in addition to the rollers (B), a ball (N) must be used as a pivot point. I support you. The balls (N) are arranged at opposite corners of the movement groove (D), and when the roller (B) passes through the movement groove (D), they fall into the movement 1 (D). The chassis (A) is supported by the balls (N) so that the chassis (A) can smoothly pass through the cross section of the moving groove (D) without wobbling. However, by attaching the rollers (B) to the chassis (A) and placing balls (N) at the cross section of the rail, the chassis (A) can move straight on the rails and change direction at the cross section. However, the undercarriage (a) will sway laterally while driving, and the undercarriage (a) will come into contact with the inner surface of the rail, which will hinder the running. horizontal wheel (to)
This prevents lateral vibration.

By the way, by attaching the balls (N) to the corners of the moving grooves (D) that cross each other in this way, the chassis (A) can be moved along the moving grooves (D).
It is possible to pass through (d) and change the direction of travel at the same time, but if the chassis (A) is supported by the ball (N), the chassis (A) will be in a very unstable state. . That is, since the ball (N) is allowed to rotate in all directions, the position of the chassis (A) at the cross section is not determined. Therefore, even if the chassis that has entered the cross section moves in the same direction or changes direction, the suspension shaft (C) will not hit the corner of the movement groove (D). This prevents smooth movement.

Therefore, Japanese Patent Application No. 141320/1983 exists for a hanging traveling device developed to solve this problem. This suspended traveling device uses vertical wheels in place of the above-mentioned balls, and the vertical wheels are 45° with respect to the moving groove.
@It is tilted and pivoted to support the chassis entering the cross section. Since it is a wheel, it is only allowed to rotate in one direction, and the chassis that enters the cross section is relatively stable. However, the above-mentioned inclination of 45@ with respect to the moving groove of the vertical wheels is to change the direction of movement of the undercarriage that has entered the slot, but the vertical wheels and the undercarriage exhibit line contact rather than point contact, and the direction of movement of the undercarriage is Due to the different rotational directions of the vertical wheels, sliding friction inevitably impedes the movement of the chassis. In other words, the vehicle chassis and the panel cannot be moved unless the panel is pressed with a larger force.

(Objective of the present invention) In this way, in the panel suspension setting device, when the vertical wheels are pivoted at an angle of 45 degrees with respect to the moving groove as means for supporting the chassis at the cross section, the above-mentioned method is adopted. A problem exists. The present invention is aimed at solving this problem, and provides a suspended traveling device that facilitates direction change at the cross section and allows pressing and moving of panels with small force. That is, the present invention is disclosed in Japanese Patent Application No. 63-141320.
This is an improvement of the panel suspension traveling device related to the issue.

(Structure of the present invention) The panel hanging traveling device of the present invention is disclosed in Japanese Patent Application No. 63-1413.

The connecting rod extends upward to form an open base with the hanging shaft, and the contact portions are formed on four sides at a certain distance from the connecting rod as the center of the connecting rod, in the same direction as the rail. There is. Here, although the above-mentioned lateral vibration prevention member and the contact portion are provided on the upper plate, it is not necessarily necessary to extend the connecting rod from the chassis to form the upper plate. A horizontal vibration prevention member such as a horizontal wheel may be provided.
