Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention provides a right-angle running runner for a movable partition that has two types of running rollers oriented in different directions at 90 degrees and is capable of lightly moving a suspended partition panel vertically and horizontally. Regarding.

Prior Art A system in which a unidirectional runner, which has only rollers running in the same direction, is used while changing the direction of the movable partition runner, which suspends and runs the partition panel and moves the partition panel in two directions, vertically and horizontally. There are two types: one that uses a right-angle running runner, in which two types of running rollers running in different directions are incorporated into one runner.

Right-angle running runners have a high-level part and a low-level part on the running path of the non-gauge rail that guides the runner, and only the running rollers for the direction in which the runner moves are in the high-level part, corresponding to the direction of movement of the runner. It is designed so that it touches the ground and the rollers for the other direction are raised from the lower level, and at the cross point where two non-ga rails cross at right angles,
The running direction of the runner can be freely selected without changing the direction of the runner. Therefore, unlike unidirectional runners, right-angle runners do not require a rotary mechanism to change the direction of the runner to be built into the cross point, and there is no need to wait for time for the runner to change direction. The structure can be simplified, and the operation is also extremely simple.

Problems to be Solved by the Invention Although the right-angle running runner has excellent operability as described above, at the cross point of two rails running in different directions, the running rollers running in different directions are both at the height of the running path. The problem is that the escape operation from the cross point is difficult because the running roller for the other direction becomes an obstacle to running when the runner is in contact with the level part and runs in either direction. In addition, even if the runner moves straight at the cross point without changing its running direction, the opening for passing the hanging bolts that opens in the running path will become an obstacle when crossing the hanger rail in the other direction. There was also the problem that smooth operation could not be obtained.

Therefore, an object of the present invention is to provide three pairs of running rollers for the first direction and three pairs of running rollers for the second direction that are orthogonal to each other, and when the partition panel is pushed in a predetermined direction, the runners are tilted and the partition is separated. To provide a right-angle running runner of a movable partition that is devised so that all the running rollers in the direction perpendicular to the direction of movement of the panel are lifted up so that the operation at the cross point can be performed with the same slight external force as at the straight section. It's about doing.

Means for Solving the Problems The structure of the present invention, which is a distant relative of the object, includes a runner main body having a hanging bolt for suspending a partition panel;
A running roller for a first direction and a running roller for a second direction are disposed on the runner body at the same ground level and are perpendicular to each other, and the running roller for the first direction and the running roller for the second direction are provided. each consists of two pairs of end running rollers and a pair of intermediate running rollers 1, a running roller for the first direction is disposed between the axes of the end running roller for the second direction, and The gist is that the running rollers for two directions are disposed between the axes of the end running rollers for the first direction.

Note that the suspension bolts can be rotatably suspended from the runner body, and the partition panel can be pivotally suspended.

According to this configuration, the right-angle running runner includes a first direction running roller and a second direction running roller perpendicular to the first direction running roller in the runner body.
Since the runner is also equipped with running rollers for different directions, by using dedicated running paths for different directions, the runner can run in two directions without having to change the direction of the runner.

The running rollers for each direction are composed of three pairs of running rollers: a pair of end running rollers arranged at each of the front and rear ends of the runner, and a pair of intermediate rollers arranged between the end running rollers. Become. Therefore, even if one pair of running rollers has poor grounding, the other two pairs of running rollers can maintain the horizontal position of the runner, and therefore there will be no problem when passing the cross point. do not have.

Further, the positional relationship between the running rollers for the first direction and the second direction is such that the three pairs of running rollers for the first direction are arranged between the axes of the end running rollers for the second direction, and Three pairs of running rollers for the second direction are arranged between the axes of the end running rollers for the first direction, and all the running rollers are at the same ground contact level.

Therefore, by tilting the runner using an arbitrary end running roller as a fulcrum, all of the other running rollers except for the end running roller serving as the fulcrum can be levitated. Therefore, the runner can move smoothly in the running direction of the end running roller serving as the fulcrum. Note that this relationship holds true regardless of which end running roller for any direction is used as a fulcrum, so at the cross point, simply pushing the partition panel in a predetermined direction and tilting the runner will cause the runner to run. The direction can be changed arbitrarily.

In addition, those equipped with rotatable hanging bolts allow the partition panel to be hung in any direction regardless of the running direction of the runner, and also use hanging bolts that allow the partition panel to be hung in a swingable manner. In some cases, the runner can be tilted freely while keeping the partition panel vertical.

It works as described above.

Example Examples will be described below with reference to the drawings.

The right-angle running runner of the partition panel includes a runner main body 10 consisting of a rectangular base 11 and a circular base 12, and a first direction running roller 2 for running the runner in the vertical and horizontal directions.

Note that the intermediate running rollers 20b, 30b and the end running rollers 20a, 30a are independent of their respective diameters.
It is assumed that the height is adjusted so that the ground points are at the same ground level.

The overall arrangement relationship of the running rollers 20, 20..., 30, 30... attached to the four bearing blocks 13, 13... is three pairs of running rollers 2 for the first direction.

... is located between the axes ASA.

A hanging bolt 40 for hanging the partition panel P is attached to the center of the circular base 12 (second
figure).

The suspension bolt 40 consists of a threaded rod 41 and an adjusting member 42a that is screwed onto the threaded rod 41 and whose height can be adjusted. The adjustment member 42a and the swing bracket 42b that engages with the adjustment member 42a and is fixed to the partition panel P side are the swing connection portion 4 that allows the partition panel P to swing relative to the hanging bolt 40.
2 is formed. Note that the swing connection portion 42 may be a ready-made swing connection mechanism, such as a universal joint, as long as it can safely support the weight of the partition panel P.

The threaded rod 41 is connected to the circular base 12 via a thrust bearing 12b housed in the bearing housing 12a.
It is suspended so that it can rotate freely.

Such a right-angle running runner is used by being inserted into the channel-shaped hanger rail 50.

The hanger rail 50 has an upper surface 50a and side surfaces 50b, 50.
b, and a bottom surface 50 c s 50 divided by an opening S continuously formed for passing the hanging bolt 40.
c, and the right angle running runner has side surfaces 50b, 50
The vehicle runs within the Hunger Rail 50 using its bottom surface ';oc, 50C as a running path, while its running direction is restricted by b.

However, on the bottom surface 500% 50C, a spacer plate 51.51 is laid along the opening S, and within the running path,
A high level portion formed by this spacer plate 51.51,
A low level portion is formed by the remaining bottom surfaces 50c, 50c. Therefore, when the right-angle running runner runs in the first direction, the running rollers 20, 20, . . .
are grounded on the spacer plate 51.51, and the second
All the direction running rollers 30, 30... are on the bottom surface 50.
If it floats from the low level part of c, 50c and moves in the second direction, similarly, only the running rollers 30, 30... for the second direction touch the ground, and the others run in a floating state. The running rollers 20.20...30.30.
. . . and the spacer plate 5L51 are assumed to have a fixed relative positional relationship (FIGS. 2 and 3).

The right angle runner changes its direction at a cross point Z where two hanger rails 50,50 intersect at a right angle (FIG. 3).

At the cross point Z, the two orthogonal non-galactic rails 50, 50 intersect, so the first cross point of the right angle runner
The grounding conditions of the direction running rollers 20, 20, . . . and the second direction running rollers 3Q, 30, . . . are equal to each other. That is, for any direction running rollers 20, 20..., 30°30..., the intermediate running rollers 20b, 20b, 30b, 30b are
The other traveling rollers 20., which are located above the open bottom portions S and S of the hanger rail 50.50, cannot touch the ground.
20...30.30... are all grounded on the spacer plates 51, 51....

Now, let us consider the case of escaping from the right-angle running runner at cross point Z in the second direction (direction of arrow X in FIG. 4). If the partition panel P is pushed in the direction of the arrow X1 in the figure, the end running rollers 20a, 20a, etc. for the first direction will become a running obstacle, and the right-angle running runners will not be able to move easily. , only the partition panel P moves slightly in the second direction. Therefore, a positional shift occurs between the right-angle running runner and the partition panel P, and the runner body 10
End running rollers 30a, 30a for the second direction on the opposite side
It is tilted using the fulcrum as the fulcrum (see the same figure). Note that, at this time, since the partition panel P is suspended via the swing connecting portion 42 of the hanging bolt 40, it moves in parallel while hanging vertically, regardless of the attitude of the runner body 10.

As the runner main body 10 is tilted, the advancing side end running roller 30a130a is lifted up.

At this time, the end traveling roller 20a120a for the first direction
... are lifted up at the same time, and only the end running rollers 30a, 30a for the second direction on the opposite traveling side are brought into contact with the ground. Therefore, the right-angle running runner starts moving with a light operating force in accordance with the direction in which the partition panel P is pushed. Note that the state in which the runner body 10 is tilted will continue until the positional deviation between the right-angle running runner and the partition panel P is resolved, so by pushing out the partition panel P at the beginning of the operation, the positional deviation can be avoided. The right-angle running runner can escape from the cross point Z by the time of resolution. Moreover, the end traveling roller 30 as
30a passes over the opening S, the intermediate running rollers 30b, 30b are connected to the advancing side spacer plate 5L.
51, the end running rollers 30a, 30a on the opposite side of the movement do not fall deeply into the opening S, and the right-angle running runner can smoothly escape from the cross point Z. can.

Nao, the right-angle runner enters cross point Z,
When passing straight through this, the running rollers 20120..., 3
0.30..., at least two pairs on the running direction side can maintain their ground contact state, so smooth running performance can be maintained at this time as well.

DETAILED DESCRIPTION OF THE INVENTION According to the present invention, as described in detail, the first direction running rollers include two pairs of end running rollers and a pair of intermediate running rollers disposed therebetween; Even if the runner body is tilted using the end running roller on either side as a fulcrum by combining the running rollers for the second direction related to the arrangement at the same ground level, all the running rollers for the other direction By making the running rollers float up, it is possible to pass through a cross point with a slight operating force and change direction at the cross point, without causing any running obstruction caused by the running rollers for the other direction. effective.

In addition, by providing three pairs of running rollers in each direction, there is no risk of any hindrance when crossing the opening of the hangar rail, and therefore smooth running performance is achieved even when passing straight through a cross point. It also has the excellent effect of being able to maintain the
