Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a direction changing device for a moving partition for turning the traveling direction of a large moving partition that suspends a moving panel from a hanger rail via a runner.

2. Description of the Related Art When setting up an event venue in a museum, school, hotel, etc., a large space may be divided by moving partitions to form a space suitable for the scale of the event.

In this case, the moving partition is often required to have the same sound insulating properties, heat insulating properties, and aesthetic properties as the wall, and the moving panel is remarkably increased in size and weight. That is, the moving partition is mainly composed of a moving panel suspended from a hanger rail, and it is not uncommon that the weight of one moving panel exceeds 1 ton. Therefore, the runner that runs in the hanger rail while supporting such a heavy moving panel is also enlarged, and some runners include rollers having six wheels or more.

The applicant previously proposed a device for changing the traveling direction of a large moving panel, which is interposed at an intersection of hanger rails (Japanese Patent Application No. 62-258656). In this model, the runner of the moving moving panel is held in the horizontal rotating part in the device, and a force is applied to the moving panel in an oblique direction to give a rotational moment to the horizontal rotating part to move the runner. By rotating the movable panel in a predetermined direction, the work of turning the movable panel is realized.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention When the conventional technique is used, the runner can be rotated only by manual operation.
There is a problem that it is not always easy to give a sufficient rotation moment for rotating the runner.

In addition, in the construction site of the event venue where quickness is required for all the work, it is essential to perform the turning work of the moving panel in a short time, and when it is done manually, this request cannot be sufficiently satisfied. There is also a big problem.

Therefore, in view of the circumstances of the prior art, an object of the present invention is to provide a rotating frame body having a runner holder, a fixed frame body, and a drive mechanism, so that the turning operation of the moving panel can be performed easily in a short time. It is an object of the present invention to provide a new moving partition turning device that can be carried out.

Means for Solving the Problems The structure of the present invention for achieving the above-mentioned object includes a rotary frame body having a runner holder in a lower portion, a fixed frame body for rotatably supporting the rotary frame body, and a rotary frame body. The runner holder holds the runner that hangs the moving panel and rotates horizontally.The rotating frame has a hollow shaft for driving, and the hollow shaft has a runner holder. The main point is to install a sliding shaft for detecting the entering runner so that it can move up and down.

Action According to the configuration of the invention, since the runner holder can hold the runner that has entered the runner holder and rotate horizontally, by operating the drive mechanism,
The rotary frame can freely change the direction of the runner via the runner holder. The drive mechanism can be driven either electrically or manually, and according to the former, anyone can easily rotate the runner in a short time. Also, according to the latter, even when electric power cannot be used due to, for example, a power failure, it is possible to easily deal with the problem.

On the other hand, the sliding shaft mounted inside the hollow shaft for driving the rotating frame is
Since the runner that enters the runner holder can be detected, an appropriate interlock can be configured when driving the runner holder, and the safety of operation can be improved.

Further, the lower end of the sliding shaft 28 protruding into the runner holder 23 is
It is shaped like a smooth dome. A limit switch LS1 is arranged above the sliding shaft 28 via a bracket 15, and the limit switch LS1 is operated by the vertical movement of the sliding shaft 28.

Therefore, the rotary frame 20 having the runner holder 23 at the bottom is
It is rotatably supported by the fixed frame body 10 via the bearings BR1 and BR2, and can be horizontally rotated in the forward and reverse directions via the worm wheel 24 and the hollow shaft 25.

The drive mechanism 30 is composed of two systems, electric and manual. The electric system comprises a motor M, an input shaft 31, a conversion gear G, a transmission shaft 32 and a worm 33 (FIGS. 1 and 2), and a fixing frame via a mount base 34 and bolts 34a, 34a. It is attached to the body 10. The input shaft 31 is connected to the motor M and is disposed downward, and is connected to a horizontal transmission shaft 32 via a conversion gear G that meshes with each other. Warm 33
It is attached to the tip of the transmission shaft 32 and meshes with the worm wheel 24 of the rotary frame body 20.

In the manual system, the input shaft 31 is manually rotated by the handle H (Fig. 1). Downward input shaft 31 connected to the motor M
Has a lower end portion 31a formed in a substantially quadrangular prism shape, and is located at substantially the same height as the lower surface of the hanger rail HR. The handle H has a recessed portion H1 formed at the tip end portion thereof which can be detachably fitted to the lower end portion 31a of the input shaft 31, and the length L thereof is
The length is sufficient so that a worker in a standing state can rotate the input shaft 31 without any trouble.

A pilot lamp PL that can be checked by the operator from below is arranged near the lower end 31a of the input shaft 31. It is assumed that the pilot lamp PL is lit when the rotary frame 20 is at the both ends of the horizontal rotation angle of 90 degrees and one of the limit switches LS2 and LS3 is operating. In addition,
At this time, each end surface of the runner holder 23
Correctly face R, HR ... (Fig. 3).

The runner R, which is combined with the direction changing device for moving partitions, has a total of six vertical rollers R2, R2, ... Stick the push-up piece R3 to the upper surface,
Further, a suspension bolt R5 for suspending the moving panel P is vertically provided at the center of the lower surface of the runner body R1. A guide roller R4 is attached to the suspension bolt R5. The push-up piece R3 is a plate material in which a shallow lateral groove R6 is formed in the center of the upper surface and both sides thereof are formed into stepped slopes R7 and R7. The thickness of the push-up piece R3 is selected so that the lower end of the sliding shaft 28 of the rotary frame body 20 can be pushed up when the runner R enters the center of the runner holder 23.

The runner R is attached to one moving panel P, one at each of the front part and the rear part thereof, that is, at two positions in total, and the runners R and R support the total weight of the moving panel P. Further, each runner R is assumed to be rotatable with respect to the moving panel P.

The direction changing device for moving partitions having such a configuration is installed at the intersection of orthogonal hanger rails HR, HR ... (Fig. 3). However, each of the hanger rails HR, HR ... is a channel-shaped drawing member having substantially the same cross-sectional shape as the runner holder 23 of the rotary frame 20 so that the runner R can travel inside. Through the shape members B4 and B4, the H shape member B
Is attached to.

Now, when the rotary frame 20 is at one end of the horizontal rotation angle of 90 degrees, the end faces of the runner holder 23 are continuous with the end faces of the hanger rails HR facing each other with a slight gap. Therefore, when the moving panel P is moved along an arbitrary hanger rail HR (direction of arrow K1 in FIG. 2) and the runner R on the front side in the traveling direction enters the intersection of the hanger rails HR, HR ..., The runner R is It can smoothly enter the runner holder 23. When the runner R enters the runner holder 23, the sliding shaft 28 of the rotary frame body 20 is pushed up via the slope R7 of the push-up piece R3 on the upper surface of the runner R,
Finally, it is pushed up by the concave groove R6 of the push-up piece R3 (Fig. 1). Therefore, the sliding shaft 28 operates the limit switch LS1, and the limit switch LS1 can activate the motor M after a predetermined time via a timer (not shown). That is, the sliding shaft 28 is attached to the runner holder 23.
It is for detecting the runner R entering the.

The rotational force of the motor M is the input shaft 31, the conversion gear G, the transmission shaft 3
2, the worm wheel 2 of the rotating frame 20 through the worm 33
4 is transmitted to rotate the rotating frame body 20. At this time, the runner R is held in the center by the runner holder 23 and can be horizontally rotated together with the rotary frame 20.

When the rotary frame 20 is rotated up to around 90 degrees (direction of arrow K in FIG. 2), the dog plate 26 operates the limit switch LS2, and the limit switch LS2 stops the motor M. At this time, the runner R in the runner holder 23 also rotates 90 degrees, and the runner R is directed in the direction of another hagarail HR, HR intersecting the hanger rail HR in the approach direction K1 at a right angle. You can exit in both directions K2 and K3 in Figure 2.

In this way, when the runner R on the front side of the moving panel P advances in one of the directions of arrows K2 and K3 of FIG. 2, the moving panel P is guided by the two orthogonal hanger rails HR and HR, and The direction is reversed, and subsequently the rear runner R enters the runner holder 23. Therefore, the limit switch LS
When the worm 1 is operated, the worm wheel 24 is rotated in the reverse direction via the drive mechanism 30 and the rotary frame body 20 is returned in the reverse direction of 90 degrees (the direction opposite to the arrow K direction in FIG. 2). ,
It is possible to leave in any of the directions of arrows K2 and K3 in the figure, and it is possible to complete the direction change of the moving panel P. The rotary frame 20 at this time is the dog plate 26.
The limit switch LS3 is actuated via the switch to stop.

The drive mechanism 30 can be manually operated by the handle H in case of an emergency such as a power failure (Fig. 1). For manual operation, after fitting the recess H1 of the handle H to the lower end 31a of the input shaft 31,
By turning the handle H, the input shaft 31, the conversion gear G,
Via the transmission shaft 32, worm 33, worm wheel 24,
The rotating frame body 20 may be horizontally rotated.

When the moving panel P is moved along the hanger rails HR and the runner R is inserted into the runner holder 23, the operator correctly causes the runner holder 23 to face the hanger rails HR, HR because the pilot lamp PL is lit. You can confirm that you are doing.

Other Embodiments The motor M may be automatically controlled by a timer when the runner R reaches the center of the runner holder 23, or may be manually controlled via an appropriate manual switch. The manual switch at this time may be provided at an appropriate position on the wall surface, or may be a wireless controller type remote control type.

Further, the motor M performs an automatic recovery operation so that the horizontal rotation angle of the rotary frame 20 is at a predetermined position for operating one of the limit switches LS2 and LS3 when the power is restored after a power failure or the like. Good. In the next use, it is not necessary to manually perform the rotation correction operation of the rotary frame body 20, which is more convenient.

The direction changing device for moving partitions can also be applied to three hanger rails HR, HR ... Forming a T-shaped branch point (Fig. 4). However, at this time, by providing the stopper plate T (two-dot chain line in FIG. 1) inside the runner holder 23, the runner R entering the runner holder 23 can be reliably stopped at a predetermined position. That is,
The rotating frame body 20 is made to stand by so that the stopper plate T is at a position facing the entering runner R (FIG. 4 (A)), and after the runner R enters the runner holder 23, the rotating frame body 20 is removed. When the runner R is horizontally rotated 90 degrees in a predetermined direction (arrow K4 direction in the same figure), the runner R can be turned to one of the hanger rails HR and retracted from the runner holder 23 (the same figure (B)). However, the rotating frame body 20 at this time
Must be returned to the original standby position before the subsequent runner R enters (direction of arrow K5 in the figure).

Instead of the cross shape, the runner holder 23 may be simply a linear shape capable of holding the runner R (FIG. 5). Also at this time, the rotating frame body 20 changes the direction of one runner R each time,
It is necessary to return to the original standby position.

The stopper plate T in FIG. 5 may have a short hanging length so as to engage with a stopper block (not shown) protrudingly provided on the upper surface of the runner R. The runner R having no stopper block can pass through the runner holder 23 without being stopped by the stopper plate T, while the runner R having the stopper block is forcibly stopped at the center of the runner holder 23. It is possible to automatically select the moving panel P to be converted. Further, at this time, by preparing a plurality of combinations of the hanging length of the stopper plate T and the height of the stopper block, the runner R
Can freely pass through the runner holder 23 when the stopper plate T has a short hanging length and does not engage with the stopper block, and the passage is blocked only when the two engage with each other. It is possible to selectively specify the place to turn. When the stopper plate T is provided on the runner holder 23, the sliding shaft 28 may omit the compression spring 28c.

The direction changing device for moving partitions can be applied not only to the moving panel P but also to changing the direction of the stage A having a large area (FIG. 6). Stage A is suspended via runners R, R ...
If a direction changing device is provided at each intersection of ... in correspondence with the runners R, R ..., all the runners R, R ... can be turned at the same time, so that excellent workability is exhibited. be able to.

As described above, according to the present invention, the rotating frame body including the runner holder that holds the runner and horizontally rotates is rotatably supported by the fixed frame body and rotates the rotating frame body. By providing a drive mechanism to drive, the runner
Even when suspending a heavy moving panel, it can be easily rotated horizontally via the runner holder, and the runner detection sliding shaft must reliably detect that the runner has entered the runner holder. Therefore, there is an excellent effect that the turning operation of the moving panel can be performed easily and safely in a short time.

Further, since the runner holder holds the single runner in a stationary state and horizontally rotates, the required length is short, and therefore the overall shape can be extremely compact. There is also.
