Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a guide device for a movable panel that is suspended from a ceiling rail and travels.

[Conventional technology]

In this type of panel guide device, the top center of the panel is suspended from a runner movably installed in the ceiling rail so as to be horizontally rotatable via a vertical pivot shaft. The prior art disclosed in Japanese Utility Model Application Publication No. 102839/1983 allows panels to be partitioned by running along guide rails, or to be stored with the front and back sides of each panel stacked on top of each other. has been done.

In this prior art, in order to hold the panel in a state parallel to the ceiling rail when running the panel suspended on a runner or partitioning the room, a ball provided on the top surface of the panel is connected to an opening groove on the bottom surface of the ceiling rail. It is pressed into contact with the side line by spring force.

[Problem that the invention attempts to solve]

However, when the ball is pressed into contact with the ceiling rail using a spring as in the prior art, the ball must be provided on both sides of the pivot axis of the panel relative to the runner, which only complicates the structure. However, the movement of the panel becomes heavier due to the pressure of both balls against the ceiling rail, and the noise due to the squeaking with the spring increases as both balls roll.In order to reduce this movement resistance and the squeaking noise, If the pressing force is weakened, the engagement with the ceiling rail will become looser, making it easier for the panel to come off the rail during movement or partitioning, resulting in the problem of the panel rotating unexpectedly.

Furthermore, because the panel changes its position between perpendicular to the ceiling rail and parallel to it by forcibly rotating it against the spring force, a large amount of force is required when storing or extending the panel. There are also problems with the point.

This invention allows panels to be suspended horizontally and horizontally to be reliably maintained parallel to the ceiling rails during movement or partitioning, while also preventing changes in position during movement, storage, and extension. The purpose is to make it possible to do this with light force.

[Means for solving problems]

For this reason, in this invention, we have developed a mobile system in which the center part of the upper end of the panel is suspended horizontally from a runner movably installed in a ceiling rail with a downward opening C-shaped cross section via a vertical pivot shaft. In the panel guiding device, downwardly protruding lips are provided on both sides of the opening groove on the lower surface of the ceiling rail along the longitudinal direction of the ceiling rail, while lips are provided on the upper end surface of the panel at an appropriate distance from the pivot shaft. In a shifted position,
A horizontally rotating guide trochanter that can be fitted between the two lips is provided, and a notch for engaging and disengaging the guide trochanter is provided at an appropriate location on one of the lips, and a notch for engaging and disengaging the guide trochanter is provided on one of the lips. An attitude-maintaining roller having a rotational axis extending perpendicularly to both the front and back surfaces of the panel is disposed at the opposite end of the end surface across the pivot shaft, and of both the attitude-maintaining rollers, the guide A posture-maintaining roller placed near the trochanter is brought into contact with the lower surface of the ceiling rail on the outside of the lip forming the notch, while a posture-maintaining roller placed on the opposite side of the guide trochanter across the pivot shaft. The roller is configured to abut against the lower surface of the ceiling rail on the outside of the lip on the opposite side to the lip in which the notch is formed.

〔Example〕

Next, an embodiment of the present invention will be described based on the drawings. In the drawing, 1 is a ceiling rail that is attached to a ceiling surface 2 of a building, etc., and the ceiling rail 1 has an opening groove along the longitudinal direction on its lower surface. It is formed with a downwardly opening C-shaped cross section, and downwardly bent lips 3, 3 are provided along the longitudinal direction at both edges of the opening groove on the lower surface.

4 is a pair of left and right trochanters 5 in the ceiling rail 1.
Runners 6 are partition panels provided movably through the runners, and at the lower end of a pivot shaft 7 vertically fitted rotatably into the center of each runner 4,
By fixing the substantially central portion of the upper surface of the panel 6, the panel 6 is suspended from the runner 4 so as to be horizontally rotatable. A horizontally rotatable guide trochanter 8 is provided on the upper surface of the panel 6 at a position shifted by an appropriate distance L from the pivot shaft 7, and the guide trochanter 8 is connected to both lips 3 on the lower surface of the ceiling rail 1. , 3, and one lip 3 of the two lips 3, 3 has a panel 6 that can be rotated at an appropriate position such as near the panel storage section provided at one end of the ceiling rail 1. Accordingly, the guide trochanter 8
A notch 9 is cut out so that the can be engaged and disengaged.

Furthermore, on both ends of the upper surface of the panel 6 with the pivot shaft 7 interposed therebetween, there are posture-maintaining trochanters 10 and 1 having rotating shafts extending in a direction perpendicular to the surface of the panel 6.
1, and the posture-maintaining trochanter 11, which is disposed near the guide trochanter 8 among the two posture-maintaining trochanters 10, 11, is attached to the ceiling at a portion outside the lip 3 in which the notch 9 is formed. The posture-maintaining trochanter 10, which is placed in contact with the lower surface of the rail 1 and on the opposite side of the guide trochanter 8 with the pivot shaft 7 interposed therebetween, is placed at a portion outside the lip 3 where the notch 9 is not formed. Bring it into contact with the bottom surface of ceiling rail 1.

In the above configuration, the panel 6 suspended from the runner 4 is prevented from horizontal rotation by the guide trochanter 8 fitted between both lips 3, 3 during movement and partitioning. , panel 6
Posture-maintaining trochanter 10 provided at both front and rear ends of the upper surface,
11 is in contact with the lower surface of the ceiling rail 1, it is prevented from tilting in the front-back direction, and the partition can be moved and partitioned while reliably keeping its upper surface and both front and back surfaces parallel to the ceiling rail 1. It will be done.

Then, when the panel 6 is moved to the end of the ceiling rail 1 and the guide roller 8 is horizontally rotated in the direction of arrow a as shown in FIG. At the same time that the child 8 is removed from between the two lips 3 through the notch 9,
Each posture holding trochanter 10, 11 slides through the lower surface of the ceiling rail 1, and the panel 6 changes its posture to a posture perpendicular to the ceiling rail 1, and in this state moves toward one end of the ceiling rail 1. , each panel 6 can be stored in a stacked state.

Conversely, when the panel 6 is pulled out from the stored state to the position of the front notch 9 and the panel 6 is rotated in the direction opposite to arrow a so as to be parallel to the ceiling rail 1, the guide trochanter 8 will be removed from the notch. At the same time as fitting between both lips 3, 3 via part 9, both posture maintaining trochanters 10, 11 slide onto the lower surface of ceiling rail 1,
The panel 6 is moved with its upper end surface and both front and back surfaces parallel to the ceiling rail 1.

In this way, the guide trochanter 8 and the two posture holding trochanters 10 and 11 reliably maintain the posture of the panel 6 during movement and partitioning, and
The posture can be changed simply by horizontal rotation at the notch 9 position, and storage and unfolding operations can be performed with extremely light force. Furthermore, since the guide trochanter 8 and the posture-maintaining trochanters 10 and 11 are only in contact with the lip 3 and the ceiling rail 1, respectively, no squeaks are produced when the panel 6 moves. , it can be moved with extremely light force.

[Functions and effects of the idea]

The present invention is constructed as described above, and the guide trochanter is fitted between the lips protruding downward from the lower surface of the ceiling rail, so that the panel can horizontally rotate during traveling and partitioning. On the other hand, the posture-maintaining trochanter provided on the opposite front and rear sides of the top surface of the panel is in contact with the bottom surface of the ceiling rail, which prevents the panel from tilting in the front-back direction, and the panel is prevented from tilting in the front-back direction. Also, during partitioning, the upper surface and both front and back surfaces are reliably maintained in a posture parallel to the ceiling rail, and this has the effect of reliably preventing unexpected rotation during movement and partitioning.

Also, among the posture maintaining rollers provided on the upper end surface of the panel on the opposite front and rear sides, the posture maintaining roller placed near the guide trochanter is brought into contact with the lower surface of the ceiling rail on the outside of the lip forming the notch. On the other hand, since the posture maintaining roller placed on the opposite side of the guide trochanter is in contact with the lower surface of the ceiling rail on the outside of the lip on the opposite side to the lip in which the notch is formed, the guide trochanter is not cut. As it engages and disengages from the notch, the posture-maintaining trochanter slides in and out of the lower surface of the ceiling rail, and can easily detach and detach from the ceiling rail without any special processing on the ceiling rail. Although the panel can be brought into contact with the panels and its posture can be reliably maintained during movement and partitioning, it is possible to change the posture when storing or extending the panel with extremely light force.

Since the guide trochanter and the posture-maintaining trochanter simply contact the lip and the lower surface of the ceiling rail, the panel can be moved with a light force.
