Description

[Detailed description of the invention] This invention suspends and supports a partition panel by means of a runner that is movably placed on a partition rail attached to the ceiling, etc., and when installing a partition, the partition panel This relates to a movable partition in which the partition is constructed by moving the panel to a desired position along the rail, or when the partition is completely removed, the partition panel is moved along the rail to a storage position and stored, In particular, it relates to rails used in such movable partitions.

The above-mentioned type of movable partition includes a rail with a guide groove extending vertically in the center, generally a cross section with the above-mentioned guide groove on the bottom, and a rectangular rail with running rolls ( For example, a runner equipped with running wheels) is mounted, and the upper part of the partition panel is attached to the lower end of the support shaft that hangs down from the center of the runner base and projects downward through the above-mentioned guide groove. There is a structure in which the partition panel can be freely run along the rail by running rolls on the guide surfaces on both sides of the guide groove of the rail. This kind of moving partition is
Even a fairly heavy partition panel can be easily moved along the rails. However, although this type of moving partition can be used advantageously on straight rails, cross-shaped, T-shaped,
It cannot be applied to rails with L-shaped intersections. That is, at such a rail intersection, the running direction of the runner cannot be changed.

In order to correct the disadvantages of the movable partition as described above, at present, instead of the above-mentioned runner with running rolls on both sides of the runner base, a runner with running rolls at four positions perpendicular to each other with respect to the center of the runner base is used. When a runner is used to move along one rail, the runner is moved on the rail by a pair of running rolls located on both sides with respect to the direction of movement;
When changing direction at the intersection and moving along another rail, the moving partition is structured so that it is run by another pair of running rolls, that is, a pair of running rolls located on both sides with respect to the new running direction. is widely used. However, even with this type of movable partition, the running roll falls into the guide groove of the rail at rail intersection points, especially cross-shaped intersection points, so the runner cannot move smoothly from one rail to the other. The drawback is that it cannot be moved.

In order to correct the above drawbacks, a runner is used in which main running rolls are provided at four positions perpendicular to each other with respect to the center of the runner base, and auxiliary running rolls are provided at positions between adjacent main running rolls. death,
The running surface of the auxiliary running roll is set slightly higher than the running surface of the main running roll, and during rail running, the main running roll runs on the rail, and at the intersection point of the rail, the main running roll runs into the guide groove of the rail. A movable partition that allows the sub-travel roll to rest on the guide surface of the rail and prevent the main travel roll from falling completely into the guide groove when it falls, allowing for a smooth change in running direction. has been proposed and is now commonly used.

This movable partition allows the runner to move easily along the rail, and also allows the runner to pass through a cross-shaped intersection point and change direction smoothly at the intersection point. direction change cannot be performed smoothly. This is L
When the intersection point of the shape or T-shape is reached, all of the main running rolls do not fall into the guide groove, but one or two of the main running rolls are located on the guide surface of the rail, and the roll base is This is caused by an unbalanced state.

The object of the present invention is to eliminate the above-mentioned drawbacks and to provide a movable partitioning rail that can smoothly change direction at the T-shaped section or the L-shaped section.

The movable partition rail according to the present invention suspends and supports a partition panel by means of runners running on a rail having a guide groove extending vertically in the center. 4
A type of movement in which a main traveling roll is placed at a certain position and a auxiliary traveling roll is placed between adjacent main traveling rolls, and the running surface of the auxiliary rolling roll is slightly higher than the running surface of the main traveling roll. In rails used for partitions, the rails are T-shaped or L-shaped.
This is characterized in that a notch is formed in the guide groove so that the guide groove of the rail has a cross shape at a position where the rails intersect.

This will be explained below with reference to the drawings.

1 and 2, a partition panel 4 is suspended and supported by a runner 3 running on a rail 2 having a rectangular cross section and having a guide groove 1 extending vertically in the center. Main running rolls 6 are arranged at four positions perpendicular to each other with respect to the center of the runner base 5, and auxiliary running rolls 7 are arranged between adjacent main running rolls. A type of movable partition is shown which is raised by a slight height H above the running surface of the running rolls. In the figure, reference numeral 8 indicates a panel support shaft that hangs down from the center of the runner base 5 and projects below the rail through the guide groove 1.

In the above movable partition, when the runner 3 runs along the rail 2, the pair of main running rolls 6 located on both sides in the running direction run on the guide surfaces on both sides of the guide groove 1 of the rail 2. do,
Move panel 4. At this time, the sub-travel roll 7 is in a state where it is floating by a height H from the guide surface of the rail. When the runner 3 comes to the intersection of the cross-shaped rails as shown in FIGS. 3 and 4, the entire main traveling roll 6 tries to fall into the guide groove 1 of the rail, but the runner base 5 After descending by the height H, the auxiliary running roll 7 rests on the guide surface of the rail to prevent the main running roll 6 from falling into the guide groove 1. Therefore, no matter which direction the runner advances from this state, the main running roll 6 can smoothly move onto the guide surface of the rail 2, and therefore,
Passage through a cross-shaped intersection and change of direction at this intersection are both facilitated.

However, the above runners have problems when running at T-shaped intersections and L-shaped intersections.

FIGS. 5 and 6 are diagrams for explaining the running state of the runner at the T-shaped intersection of the rails.
In FIG. 5, it is assumed that the runner 3 moves along the rail 2 in the A direction, changes direction at a T-shaped intersection, and moves in the B direction. At this crossing point, the main running roll 6 shown on the lower side of FIG. 5 attempts to fall into the guide groove 1. At this time, the two auxiliary running rolls 7 on the lower side of FIG. 5 come into contact with the guide surface of the rail 2 to prevent the main running roll 6 from falling completely into the guide groove 1. However, in this state, the main running roll 6 remains in contact with the guide surface of the rail 2 because the guide groove 1 does not exist under the main running roll 6 shown on the upper side of FIG. FIG. 6 is a side view of this state.

As shown in FIG. 6, when the runner 3 is changed direction at the T-shaped intersection and attempts to advance in the direction of arrow B, the main running roll 6 on the left side in FIG. 1, but is kept from falling completely into the guide groove 1 by the action of the sub-travel roll 7, so that the main travel roll 6
does not impede progress in direction B, but
In FIG. 6, the main traveling roll 6 on the right side is the rail 2.
Since the weight of the panel is in contact with the guide surface of the runner, in order to move the runner in direction B, the main traveling roll 6 must be moved against the rail against extremely large frictional resistance. shall slide defensively on the guide surface. It is extremely difficult, if not impossible, to cause the main traveling roll to slide in this manner, and smooth running cannot be expected.

At the L-shaped intersection, the runner becomes even more difficult to run.
When changing direction at a U-shaped intersection, first, when the runner enters the intersection, the front main running roll in its traveling direction must be placed on the guide surface of the rail in the opposite position to that shown in Figure 6, and then slid along that guide surface. Then, in the traveling direction after the direction change, the rear main running roll in its traveling direction must be slid along the guide surface of the rail in the same manner as in Figure 6.

In order to smoothly change the direction of the runner at the T-shaped and L-shaped rail crossing points as described above, the present invention provides a guide groove in the rail at the position where the rail intersects the T-shaped or L-shaped rail. A notch was formed in the guide groove so that it had a cross shape.

An embodiment of the invention is shown in FIGS. 7 and 8.

FIG. 7 shows an embodiment in which the present invention is applied to a T-shaped intersection, in which a notch 1a is formed in the guide groove 1 so that the guide groove 1 has a cross shape at the T-shaped intersection. FIG. 8 shows an embodiment of the present invention in which the present invention is applied to an L-shaped intersection point, and the guide groove 1 has notches 1b and 1c so that the guide groove 1 has a cross shape at the L-shaped intersection point. is formed.

That is, in FIG. 7, in addition to the guide groove 1 extending in three directions, where the rails intersect in a T-shape, there is a notch 1 that makes the intersection of the T-shape approximately cross-shaped.
a is provided on the guide surface of the partition rail.
In FIG. 8, where the partition rails intersect in an L-shape, in addition to the guide groove 1 that intersects in an L-shape and extends in two directions, there is a notch 1b that makes the intersection of the L-shape approximately cross-shaped. , 1c are provided.

Since the present invention has the above-described structure, when the runner 3 changes direction from the direction of arrow A to the direction of arrow B shown in FIG.
In FIG. 7, the upper and lower main running rolls 6 move on the rails, and when they come to the intersection, the main running rolls 6 fall into the notch 1a and the guide groove 1.
Before the main running roll completely falls into the notch and the guide groove, the auxiliary running roll 7 comes into contact with the guide surface of the rail, and the direction is changed in the direction of arrow B by the auxiliary running roll 7. At this time, the main traveling roll 6
Unlike conventional partition rails, the partition panel is located within the notch 1a as shown in FIG. 9, so it does not become an obstacle when the partition panel is moved in the direction of arrow B. Further, unlike the conventional example shown in FIG. 6, the runner 3 is not tilted and the entire weight of the partition panel is not applied to one running roll, thus improving the durability of the running roll.
