Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a moving partition, in particular, a large moving partition of a type in which a moving panel is hung from a hanger rail via a runner to turn the traveling direction at right angles. , A direction changing device for moving partitions.

Conventional technology In various event facilities such as museums, schools and hotels,
Moving partitions are widely adopted to freely change the floor area of a room according to the scale of the event.

Thus, the moving partition used for such purpose is simply
Not only is it necessary to partition the floor of a large room, but it is also necessary to effectively block the noise from the adjacent room that is partitioned.Therefore, many of these take the form of so-called sound insulation moving walls that reach the floor from the ceiling. The current situation is that

Such a large moving partition is composed of a moving panel hung on a hanger rail as a main member, and the surface of the moving panel can be finished to have the same appearance as a fixed wall forming the periphery of the room. The weight of such a moving panel becomes extremely large, and one moving panel has one
It is not uncommon to exceed tons. Therefore, for the runner that hangs the moving panel and travels along the hanger rails, in order to effectively disperse the large weight, a large-sized runner equipped with a large number of rollers of about 6 to 8 wheels is used. It is necessary to use a total of two sets, one set before and one after.

By the way, in order to change the traveling direction of the moving panel to a right angle, it is necessary to interpose a rotary device capable of holding and rotating the runner at the intersection of the straight hanger rails. As a device, there is known a device in which a linear hanger holder piece having the same shape as the hanger rail is attached to the lower surface of the rotating disk (Japanese Patent Publication No. 46-8).
195).

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention Therefore, according to such a conventional technique, since the rotary disk of the rotary device does not have any special rotary operation mechanism, one moving panel is operated by one runner. While hanging, by rotating the moving panel itself, it is possible to transmit the rotation moment to the rotating disc through the runner and rotate the rotating disc. There is a problem that it cannot be applied to a large moving partition in which the moving panel of (2) is suspended by two runners. That is, when the front runners of the front and rear ends enter the rotary device, only the front runners are rotated, so that the entire moving panel cannot be rotated.

Therefore, an object of the present invention is to apply a rotation moment to a runner via a rotation operation mechanism incorporated in a moving panel,
By using this rotational moment to rotate the rotary frame of the rotary device,
It is an object of the present invention to provide a new direction changing device for moving partitions, which can be applied without any trouble even when changing the direction of a large moving panel using a single runner.

Means for Solving the Problems A structure of the present invention for achieving the above object is a rotary device including a fixed frame body and a rotary frame body, and a runner that hangs a movable panel and travels along a hanger rail. The rotary frame is concentrically rotatable with the fixed frame within a range of 90 degrees. Moreover, the cross-shaped runner holder holding the runner is fixed to the lower part, and the runner is mounted in the center of the runner holder. Has a lock mechanism that allows the rotation of the rotary frame only when entering the section.For the runner, a horizontal rotation moment is applied to the runner through the rotary operation mechanism incorporated in the moving panel. The gist is that it is possible to give.

Therefore, with this configuration, when the runner that hangs the moving panel and travels enters the center of the runner holder of the rotary device, the lock mechanism is released and rotation of the rotating frame is prevented. It will be in an acceptable state. Therefore, by operating the rotation operation mechanism incorporated in the moving panel, a rotation moment can be applied to the runner, and therefore the rotating frame can be rotated via the runner, You can make a turn.

Further, the rotary frame is rotatable within a range of 90 degrees, and the rotation is allowed only when the runner is entering the center of the runner holder. There is no risk that the runner will not be able to enter and the subsequent runner will not be able to enter.

It operates as described above.

The runners 30 are provided on each side surface of a rectangular parallelepiped block-shaped runner body 31 with three vertical rollers 32, 32 ...
The push-up piece 33 is fixed to the upper surface of the runner main body 31, and the hanging bolt 34 is vertically provided at the center of the runner main body 31 (see FIGS. 1 and 3).
Figure). The push-up piece 33 has a shallow lateral groove 33a formed at the center of the upper surface thereof, and has stepped slopes 33b, 3b on both sides thereof.
It is a plate material formed on 3b. The push-up piece 33 is the runner 3
The thickness is selected so that the lower end of the sliding shaft 27 of the rotary frame body 20 can be pushed up when 0 enters the central portion of the runner holder 23 (solid line in FIG. 1). Further, the hanging bolt 34 is attached to the runner body 31 so as not to rotate.

A stepped coupling member 35 is connected to the lower end of the hanging bolt 34 via a lock nut 35a. The coupling member 35 is the thrust bearing 3

The lower part of the coupling member 35 is connected via a joint 35c.
The inside of P of the moving panel is extended long, and its lower end reaches the rotary operation mechanism 40.

The rotation operation mechanism 40 includes an operation shaft 42 axially supported by the gear case 41 via bearings 42a and 42a, and an operation shaft 4.
The bevel gears 43 and 43 are fitted in the middle of 2 and the lower end of the coupling member 35 and mesh with each other. However, the lower end of the coupling member 35 is
It is assumed that it is rotatably inserted into the gear case 41 via the bearings 44, 44. Further, the tip of the operation shaft 42 is formed in a substantially quadrangular prism shape, and the handle H is attached thereto through a round hole P2 provided on the surface of the moving panel P to rotate the operation shaft 42. It can be operated.

The operation of the direction changing device for moving partitions having such a configuration is as follows.

First, the rotary device R is installed at the intersection of the orthogonal hanger rails HR, HR ... However, the hanger rails HR, HR ... Include the runner holder 2 of the rotary device R so that the runner 30 can travel inside thereof.
3 is a channel-shaped drawing member having substantially the same cross section as that of No. 3, and is attached via the structural members B, B ... Of the building.

Now, when the rotary frame 20 is at one end of the 90-degree rotation range, the two end faces of the runner holder 23 facing each other have a small gap d with respect to each end face of the pair of hanger rails HR, HR facing each other. It is assumed that the runner 30 traveling through the hanger rail HR and approaching the rotary device R can directly enter the inside of the runner holder 23 by facing each other. That is, the end surface of each hanger rail HR is also formed in an arc shape that matches the end surface of the runner holder 23 (third part).
Figure).

On the other hand, focusing on the inside of the rotary device R in this state,
One side of the regulation plate 25 of the rotary frame body 20 is in contact with one stopper bolt 15, and the positioner 26
Is engaged with one of the positioner receiving pieces 16, and the regulation plate 25 is in a state in which its careless rotation is prevented (solid line in FIG. 2). In addition, the sliding shaft 2 of the rotary frame 20
7 is in a state of freely falling downward due to the total weight of the upper end of the rotating plate 28, and one of the positioner pins 29, 29 on the rotating plate 28 is one of the positioner receivers 17, 17 on the fixed plate 11. It is in the position corresponding to. At this time,
The sharp lower end of the positioner pin 29 is in a state of being inserted into the counter plate hole 17a of the positioner receiver 17, so that the rotary frame body 20 is in a state in which the rotation with respect to the fixed frame body 10 is locked (see FIG. 1). The two-dot chain line).

Now, consider a case where the moving panel P whose front and rear ends are suspended by the two runners 30, 30 moves along one hanger rail HR, and the front runner 30 enters the runner holder 23 ( Arrow K1 in Fig. 1).

When the runner 30 enters the central portion of the runner holder 23, the runner 30 is completely housed inside the runner holder 23 and held by the runner 30.
The push-up piece 33 pushes the sliding shaft 27 of the rotary frame 20 upward, so that the rotary plate 28 at the tip of the sliding shaft 27 is also pushed upward (solid line in the figure). Then, the positioner pin 29 is separated from the positioner receiver 17, so that the rotary frame 20 is moved to the arrow K2 in FIG.
In the direction that rotation is allowed.

Next, the rotation operation mechanism 4 incorporated in the moving panel P
When the handle H is attached to the operation shaft 42 of 0 and is rotated, this rotational force is transmitted to the runner 30 via the bevel gears 43, 43, the coupling member 35, and the suspension bolt 34. , Receives a rotational moment in the horizontal direction. Since the runner 30 receives the weight of the moving panel P, this rotational moment is effectively transmitted to the rotary frame body 20 via the runner holder 23, and therefore the rotary frame body 20 can rotate together with the runner 30. it can. However, the rotation operation direction of the handle H is set to the rotation frame 2
It is assumed that the rotation direction of 0 corresponds to the above-mentioned arrow K2 direction.

When the rotating frame body 20 rotates in the entire 90-degree rotation range, the positioner 26 engages with the positioner receiving piece 16 different from the one engaged before the start of rotation, and the regulating plate 25. Since the long side of the rotary frame 20 also comes into contact with the other stopper bolt 15, the allowable rotation angle of the rotary frame 20 can be accurately regulated to a value of 90 °.

In this way, when the direction of the runner 30 is turned 90 degrees, the runner 30 comes out of the runner holder 23 and either one of the other two hanger rails HR, HR orthogonal to the traveling hanger rail HR. Therefore, it is sufficient to start the traveling movement operation in the predetermined direction while applying the external force to the movement panel P. Further, at this time, since the runner holder 23 has a cross shape, its end surface is again in a state of facing the hanger rails HR, HR ... On the other hand, when the runner 30 advances from the runner holder 23, the sliding shaft 27 drops downward. Therefore, it is necessary to reproduce the rotation lock state of the rotary frame body 20 by the engagement of the new set of the positioner pin 29 and the positioner receiver 17. Is something that can be done.

When the two runners 30 and 30 suspending the moving panel P travel along the two orthogonal hanger rails HR and HR, respectively, the moving panel P and the hanger rail are moved as the moving panel P advances. The relative angle between HR and HR gradually changes, and when the rear runner 30 finally enters the center of the runner holder 23, the direction change of the moving panel P is completed. On the other hand, when the relative angle between the moving panel P and the hanger rails HR, HR is changing, the rotation frame body 20 is in a state where its rotation is locked, and therefore the runner 30 cannot rotate. However, the rotational moment generated in the runner 30 at this time is transmitted to the operating shaft 42 via the hanging bolt 34, the coupling member 35, and the bevel gears 43, 43, and the operating shaft 42 can be made to idle. There is no fear that unnecessary twisting force will be applied to the member. However, at this time, the handle H is preferably removed from the operation shaft 42.

When the rear runner 30 enters the central portion of the runner holder 23, the sliding shaft 27 is pushed up again, and therefore the rotation of the rotary frame body 20 is allowed. Therefore, hereinafter, in the same manner as described above, By rotating the rear runner 30 in the direction, the moving panel P can move and move in a predetermined right angle direction, and the intended purpose can be achieved. Since the rotation direction of the rotary frame 20 at this time is limited to the reverse direction of the arrow K2 in FIG. 2, the rotary operation direction of the operation shaft 42 by the handle H must also be the reverse direction of the above case. Needless to say, this is not necessary.

In the above description, the rotary plate 28 and the positioner pin 2
9, 29 and the positioner receivers 17, 17 are the runner 3
It operates by the vertical movement of the sliding shaft 27 due to the entry of 0,
A lock mechanism that controls whether or not the rotating frame body 20 can be rotated is formed. Therefore, this may be changed to any other configuration as long as the above-mentioned function can be realized. For example, positioner pin 29,
There is no problem even if the upper and lower positions of 29 and the positioner receivers 17, 17 are reversed, or the rotary plate 28 is a deformed plate cam other than a circular shape, and a fixed member that engages with the deformed plate cam at a predetermined rotation angle. It is also possible to form a locking mechanism by combining with.

As described above, according to the present invention, the rotary device including the fixed frame body and the rotary frame body and the runner are combined, and the rotary frame body is concentric with the fixed frame body and has a rotation angle of 90 degrees. It has a cross-shaped runner holder that is rotatable within a range and holds the runner in the lower part, and further has a lock mechanism that allows the rotation of the rotary frame only when the runner enters the center of the runner holder. , By enabling the rotation moment in the horizontal direction to the runner through the rotation operation mechanism incorporated in the moving panel,
The rotary frame can be positively rotated by operating the rotary operation mechanism on condition that the runner has entered the runner holder. Therefore, the rotary frame is suitable for a large moving panel using two runners. On the contrary, there is an excellent effect that the direction can be smoothly changed.

In addition, since the rotary operation mechanism is incorporated in the moving panel, a manual operation method can be easily realized for a rotary device installed on the ceiling of a building without using a special power source. In addition, there is a practically excellent effect that the entire structure can be significantly simplified.
