Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention relates to a stopper device for a movable partition for appropriately stopping a partition panel at a predetermined position.

2. Description of the Related Art In event facilities and the like, moving partitions that can freely partition the internal space according to the event scale have become widespread.
In addition, many moving partitions use large and large partition panels.

The moving partition is generally a combination of a ceiling-side hanger rail and a partition panel having a pair of runners on the upper end surface, and the partition panel can be moved lightly by pushing along the hanger rail. In addition, the hanger rail is formed in a channel shape having a slit in which the runner moving space is formed inside and the runner freely travels in the hanger rail. Further, the runner and the partition panel are connected to each other via a suspension bolt that vertically penetrates the slit.

On the other hand, for partitioning work by moving partitions, pull out the partition panel in the storage position, move it along the hanger rail to the specified wall side, sufficiently decelerate near the wall to make it adhere to the wall surface, and then the required number of partition panels. Are sequentially brought into close contact with the partition panel.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention According to such a conventional technique, the operation of moving a large and large partition panel has been a difficult task requiring caution. The heavy partition panel has a large inertia,
This is because it requires a unique operational skill to stop it accurately at a predetermined position. That is, if the partition panel stops too quickly, the heavy partition panel must be moved again, and if the stop operation is too late,
The partition panel may collide with the wall surface and damage both sides.

It may be possible to provide a stopper inside the hanger rail to stop the movement of the runner. However, if the runner collides with the stopper and suddenly stops, the impact will be large and the partition panel will be suspended. There is a concern that the bolt may break.

Therefore, an object of this invention is to dispose a hydraulic damper at the end of the hanger rail so that the large and heavy partition panel can be easily stopped at a predetermined position without applying an excessive impact load to the suspension bolt. An object of the present invention is to provide a stopper device for moving partitions.

Means for Solving the Problems The structure of the present invention for achieving the above object comprises a hydraulic damper disposed at a terminal end of a hanger rail and a support block for supporting the hydraulic damper at a predetermined position in the hanger rail. The block is fixed to the structural material that holds the hanger rail and protrudes into the hanger rail through an opening formed in the structural material and the upper frame of the hanger rail to fix the hydraulic damper so that the position of the hydraulic damper can be adjusted back and forth. And

The hydraulic damper may have a cylinder body that forms a male screw on the outer circumference, and the support block may have a screw hole into which the cylinder body is screwed.

Further, an oil pan may be attached below the hydraulic damper.

With this structure of the invention, the runner that travels inside the hanger rail collides with the hydraulic damper at the end of the hanger rail, but the hydraulic damper can effectively absorb the impact of the collision, and It is possible to stop the partition panel at a predetermined position without giving an excessive impact load. Since the support block that supports the hydraulic damper is fixed to the structural material, at this time,
There is no risk of an excessive impact load being applied to the hanger rails.

When the cylinder body of the hydraulic damper has a male screw and the support block has a screw hole, the fixed position of the hydraulic damper can be arbitrarily adjusted by rotating the cylinder body to move it back and forth.

If an oil pan is attached below the hydraulic damper, the oil pan can receive the leaked oil in the event of an oil leak of the hydraulic damper, and there is no fear that the oil will contaminate the floor surface.

Example Hereinafter, an example will be described with reference to the drawings.

The moving partition stopper device is provided with a hydraulic damper 20 at the end of the hanger rail 10 (FIG. 1).

The hanger rail 10 is formed by integrally molding a top frame 11, a pair of side frames 12, 12 and bottom frames 13, 13 into a channel shape.
A slit 13a is formed in the center of each of 3 and 13. On both sides of the slit 13a, a pair of hard ribs 14, 14 are continuously formed along the slit 13a, and at the lower end of each hard rib 14,
A lateral rib 14a is attached.

The hanger rail 10 is attached to a structural material H that is fixed to a ceiling frame or the like of a building. The structural material H is arranged with the web H1 horizontal, and the hanger rail 10 is firmly held on the lower surface side of the web H1 via a pair of L-shaped members L, L that hold the bottom frames 13, 13 from both sides. (Fig. 2). At the end of the structural material H, a backup stopper S with a cushioning material S1 is provided so as to close the end surface of the hanger rail 10 (FIGS. 1 and 3).

The hydraulic damper 20 is connected to the hanger rail via the support block 23.
It is supported in place within 10.

The hydraulic damper 20 includes a cylinder body 21 having an external thread on the outer circumference.
And a rod 22 that is internally mounted in the cylinder body 21 while being braked by hydraulic pressure.
The butting member 22a is attached. Also, the rod 22
Is slidably mounted in the cylinder body 21 and has an effective working stroke d1. Incidentally, the rod 22 is
Via a compression spring (not shown) installed in the cylinder body 21,
It is urged to extend.

The hydraulic damper 20 is fixed by a support block 23 so that its position can be adjusted forward and backward. The support block 23 is a structural material H.
Through an opening 11a formed by penetrating the web H1 and the upper frame 11 of the hanger rail 10 into the hanger rail 10. The support block 23 includes a base 23b larger than the width of the opening 11a, and the base 23b is fixed to the upper surface of the web H1 via a pair of pedestals 24 arranged on both sides of the opening 11a. The support block 23 has a screw hole 23a on the inner side of the hanger rail 10 that fits the male screw of the cylinder body 21, and the hydraulic damper 20 screws the cylinder body 21 into the screw hole 23a, and a pair of lock nuts 21a from both sides. It is fixed by tightening 21a.

An oil pan 20a is arranged below the hydraulic damper 20 (FIGS. 1 and 2). Oil pan 20a has slit 1
It is inserted into 3a and fixed via the rigid ribs 14 on both sides.

The hanger rail 10 can be used as a running path of the runner R for suspending the partition panel P (Fig. 3). In the runner R, the main rollers R1, R1 ... Roll over the upper surfaces of the bottom frames 13, 13 while straddling the slit 13a, and the auxiliary rollers R2, R2 are slit.
Rotate horizontally in 13a. Further, the runner R and the partition panel P are connected by the hanging bolt B through the slit 13a, and the partition panel P can be moved lightly by pushing along the hanger rail 10. In the hydraulic damper 20, when the runner R contacts the butting member 22a, the distance d2 between the side end surface of the partition panel P and the wall surface W is the effective operating stroke of the rod 22.
It shall be positioned to be somewhat larger than d1. Further, the hydraulic damper 20 can be adjusted in position back and forth by loosening the lock nuts 21a, 21a and rotating the cylinder body 21.

Now, when the partition panel P travels in the direction of arrow A in FIG. 3 and the runner R collides with the rod 22, the rod 22 retracts into the cylinder body 21, but since the rod 22 is hydraulically braked, The partition panel P also gradually decelerates, approaches the wall surface W, and finally stops. At this time, between the partition panel P and the wall surface W, approximately (d2
Although a gap corresponding to -d1) remains, this gap may be sealed by a not-shown sealing mechanism (so-called power closer device) built in the partition panel P. In this way, the hydraulic damper 20 can absorb the inertia caused by the traveling of the partition panel P and prevent the partition panel P and the wall surface W from colliding violently. The oil pan 20a receives oil that has leaked out in the event of an oil leak of the hydraulic damper 20, and receives the wall surface W and the partition panel P,
Prevent the floor of the venue from getting dirty.

Meanwhile, the partition panel P is moved to move the runner R to the rod 22.
When pulled away from the rod 22, the compression spring causes the rod 22 to return to its extension limit.

As described above, according to the present invention, by disposing the hydraulic damper at the end of the hanger rail via the support block, the runner running inside the hanger rail collides with the hydraulic damper and stops. Since the impact at the time of collision can be absorbed by the hydraulic damper, even when using a large and heavy partition panel, apply an excessive impact load to the suspension bolt connecting the runner and the partition panel. In addition, the partition panel can be easily stopped at a predetermined position, and since the support block is fixed to the structural material that holds the hanger rail, an excessive impact load is not applied to the hanger rail, and it is always safe. It has an excellent effect that it can be operated.
