Description

[Detailed Description of the Invention] Industrial Field of the Invention [0007] This invention is arranged so that it can move back and forth on the end face of the outer periphery of a moving panel, and after positioning the moving panel, pushes it out from the end face of the outer periphery to create a ceiling surface or floor surface. The present invention relates to a power partition device having a moving partition for closing a gap.

Conventional technology In large-scale event facilities, there are not many that are equipped with large moving partitions for effective use by dividing the internal space of the facility according to the scale and content of the event.

The moving partition consists of a hanger rail that is fixedly installed on the ceiling side and a moving panel that is movably suspended from the hanger rail by a runner that can run freely inside the hanger rail. By moving the panel to a predetermined position along the hanger rail, the internal space of the facility can be arbitrarily partitioned.

On the other hand, in order to maintain privacy and maintain the independence of the entertainment, it is generally desired that the respective internal spaces divided by the moving panel are completely isolated acoustically and visually.

In response to such demands, a power closer device has been devised in which movable seal members that can move back and forth are mounted on the upper, lower, left, and right end surfaces of a moving panel.

The power closer device mechanically interlocks a plurality of movable seal members so that they can be easily operated in a short time, and a plurality of movable seal members are simultaneously pushed out from a moving panel by a driving operation for one input shaft. Alternatively, it can be stored in a moving panel. In this product, a screw gear mechanism is arranged on the input side, and a feed screw mechanism is interposed between this screw gear mechanism and a plurality of movable seal members to rotate the screw gear mechanism by a plurality of feed screw mechanisms. The expansion / contraction operation is converted into a plurality of movable seal members and transmitted to a plurality of movable seal members. Generally, the expansion / contraction amount of each feed screw mechanism is the same as the rotation amount of the screw gear mechanism.

According to the related art, since the amount of expansion and contraction of the feed screw mechanism with respect to the amount of rotation of the screw gear mechanism on the input side is the same, for example, the gap between the moving panel and the ceiling surface, When there is a large dimensional difference between the moving panel and the gap between the floor surface and the like, it is necessary to provide mechanical play to the movable seal member on the side with the smaller gap. At this time, even after the movable seal member on the side with the smaller gap reaches the forward limit, the screw gear mechanism must continue to rotate in order to drive the other movable seal member. Is always determined by the movable seal member on the side with a large gap, and not only the rotation operation is difficult, but also a considerably long time is required.

Therefore, an object of the present invention is to prevent a plurality of feed screw mechanisms connected to the same screw gear mechanism from having different feed pitches so that the movable seal member on the side with the smaller gap closes one of the gaps. Almost at the same time, the movable seal member on the side with a large gap can close the other gap as well, the rotation operation for the screw gear mechanism is the minimum required, and a power closer device for moving partitions that can close a plurality of gaps in a short time. To provide.

Means for Solving the Problems A structure of the present invention for achieving the above object is a screw gear mechanism having an input shaft (including a worm gear mechanism and a helical gear mechanism, the same applies hereinafter), and a screw gear mechanism and a feed screw mechanism. Via a screw gear mechanism and a feed screw mechanism, and a movable seal member on the ceiling side which is connected to the upper end surface of the moving panel so as to be movable back and forth, and is movable to the lower end surface of the moving panel. The gist is that the feed screw mechanism that includes the floor-side movable seal member and that drives the floor-side movable seal member and the feed screw mechanism that drives the ceiling-side movable seal member have different feed pitches.

A multi-start screw or a ball screw can be used as one of the feed screw mechanisms.

In addition, a movable seal member on the wall side is provided on the side end surface of the moving panel so as to be movable back and forth, and the movable seal member on the wall side is
It can be driven by a horizontal feed screw mechanism that connects to a screw gear mechanism via a bevel mechanism.

Further, the movable seal member and the feed screw mechanism may be connected via a compression spring.

With such a configuration, by rotating the input shaft of the screw gear mechanism, the feed screw mechanism interposed between the screw gear mechanism and the movable seal member on the ceiling side and the movable seal member on the floor side is provided. They can be simultaneously driven to rotate, and the movable seal members on the ceiling side and the floor side move forward and backward in proportion to the feed pitch of the respective feed screw mechanisms. Here, since these feed screw mechanisms have different feed pitches, both movable seal members are required to individually set the stroke of their advancing / retreating operations while maintaining a mechanical interlocking relationship. It is possible to close the gap between the ceiling side and the floor side almost at the same time.

If a multi-thread screw or a ball screw is used for one of the feed screw mechanisms, it is possible to easily obtain a larger feed pitch than that of the other feed screw mechanism.

If a wall-side movable seal member that is driven by a horizontal feed screw mechanism and is connected to the screw gear mechanism via a bevel gear mechanism is provided, the ceiling seal and floor movable seal can be rotated by rotating the screw gear mechanism. In addition to the members, the movable seal member on the wall side can also be driven in conjunction with them.

In addition, when the movable seal member and the feed screw mechanism are connected via a compression spring, even if any of the plurality of movable seal members in the interlocking state reaches the forward limit first, the movable seal member is compressed. It is possible to drive the remaining movable member forward while compressing the spring.

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

The power closer device of the moving partition uses the moving panel P
Worm gear mechanism 10 and lead screw mechanism 2
0 and 30 and the movable seal members 21 and 31 are the main members (FIG. 1).

The moving panel P includes vertical frames P1 and P1 and horizontal frames P2 and P2.
Surface panels P3 and P3 are attached to both sides of a frame-like body that is a combination of ... And has a sufficient thickness (FIG. 2).
The moving panel P is hung by the runners R, R freely running inside the hanger rail H laid on the ceiling member of the building via the hanging bolts B, B (FIG. 1), and moves along the hanger rail H. You can do it. Therefore, gaps d1 and d2 for safely moving the moving panel P are provided between the upper end surface of the moving panel P and the ceiling surface C, and between the lower end surface of the moving panel P and the floor surface F. The gaps d1 and d2 are, for example, d1 <d2.

The movable seal members 21 and 31 are arranged along the horizontal frames P2 and P2 at the upper end portion and the lower end portion of the moving panel P over the entire width of the moving panel P so as to move in parallel.
It is possible to advance from the inside and retreat to the inside of the moving panel P (Figs. 1 and 2). Further, packings 21a, 21a, 31a, 31a made of an elastic material are attached to the end surfaces thereof to enhance the sound insulation performance of the moving panel P when it comes into close contact with the ceiling surface C or the floor surface F.

The worm gear mechanism 10 is arranged at the center of the moving panel P, and its input shaft 11 can be rotated from the surface of the moving panel P. The input shaft 11 includes a worm 11a (third part)
(Fig.), Which is combined with a vertical output shaft 12 provided with a worm wheel 12a that meshes with the worm 11a. The worm gear mechanism 10 is fixed to the mounting frame P4 via the base 10b attached to the casing 10a.

The feed screw mechanisms 20 and 30 are provided for one worm gear mechanism 10, and are respectively shaped into rectangular tubular casings 20a and 30a.
And the sliders 22 and 32 that slide inside this, and the slider 2
It consists of feed screws 23 and 33 that drive 2 and 32. The casings 20a and 30a of the feed screw mechanisms 20 and 30 are worm gear mechanisms.
Ten casings 10a are provided so as to protrude from the top and bottom so as to be sandwiched between the casings 10a. In addition, the worm gear mechanism 10
The output shaft 12 and the feed screws 23 and 33 of the feed screw mechanisms 20 and 30 are arranged in a straight line. However, the feed screw 23 of the feed screw mechanism 20 on the ceiling side and the feed screw of the feed screw mechanism 30 on the floor side
It is assumed that the screws 33 are in a reverse screw relationship with each other, and the feed pitches of the screws 33 on the floor side are larger than those on the ceiling side. The sliders 22 and 32 have female threads to be screwed into the feed screws 23 and 33, respectively, and when the output shaft 12 rotates, the sliders 22 and 32 slide in the casings 20a and 30a in opposite directions. It moves.

The movable seal member 21 on the ceiling side and the slider 22, and the movable seal member 31 on the floor side and the slider 32 are connected by a connecting member 40 (FIGS. 1 and 2), and the movement of the sliders 22 and 32 is controlled by the movable seal member. Can tell 21 and 31.

Each connecting member 40 is a main rod on the side of the feed screw mechanisms 20 and 30.
41, a pair of branch rods 43, 43 arranged on the movable seal members 21, 31 side, and a horizontal member 42 connecting these. The main rods 41, 41 and the sliders 22, 32 of the feed screw mechanisms 20, 30 are different from the male screw portions 41a, 41a of the main rods 41, 41.
Is screwed into the female threaded portions formed at the ends of the sliders 22 and 32 for connection (FIG. 3). The floor-side horizontal member 42 and each branch rod 43 are connected via a compression spring S (second
In the figure), even after the movable seal member 31 on the floor side reaches the floor surface F, the main rod 41 can still move so as to compress the compression spring S via the horizontal member 42.

The power closer device of such a moving partition has the operation handle HL mounted on the input shaft 11 of the worm gear mechanism 10,
By rotating the input shaft 11, the feed screw mechanisms 20 and 30 on the ceiling side and the floor side can be driven (FIGS. 2 and 3). At this time, the feed screws 23 and 33 rotate in the same direction, but since the feed screws 23 and 33 are reverse screws to each other,
Depending on the rotation direction of the input shaft 11, the sliders 22 and 32 may be advanced from the casings 20a and 30a, or
It moves forward and backward so as to move backward within 20a and 30a. Here, it is assumed that the input shaft 11 is rotationally operated so that the sliders 22 and 32 advance from the casings 20a and 30a.

The advancing operation of the sliders 22 and 32 is transmitted to the ceiling-side and floor-side horizontal members 42 and 42 via the main rods 41 and 41, and the ceiling-side and floor-side movable seal members 21 and 31 are moved from inside the moving panel P. Push it out. Here, since the feed pitch of the floor-side feed screw 33 is larger than the feed pitch of the ceiling-side feed screw 23, the movement amount d31 of the floor-side movable seal member 31 with respect to the same rotation amount n of the input shaft 11 is The moving amount d21 of the movable seal member 31 on the ceiling side is larger than that (FIG. 4). Therefore, despite the gaps d1 and d2 between the ceiling side and the floor side being d1 <d2, the movable seal member 31 on the floor side almost simultaneously with the movable seal member 21 on the ceiling side reaching the ceiling surface C. The floor surface F can be reached (Figs. 2 and 4). Therefore, the floor-side gap d2 can be blocked at the same time by applying a rotation operation to the input shaft 11 sufficient to block the ceiling-side gap d1. However, the movable seal member 31 on the floor side connected via the compression spring S is adjusted so as to reach the floor surface F slightly earlier by the amount of rotation n1. By driving the movable seal member 21 on the ceiling side while the spring S is compressed, the movable seal members 21 and 31 can be brought into close contact with the ceiling surface C and the floor surface F, respectively.

When the clearance d1 on the ceiling side and the clearance d2 on the floor side are d1> d2 due to the installation conditions of the movable panel P, it is possible to use the feed screw mechanism 30 having a large feed pitch on the ceiling side. There is no end. In addition, the compression spring S is
Regardless of the floor side, it suffices to interpose it on the connecting member 40 on the side that reaches the ceiling surface C and the floor surface F in advance, but by interposing it on both the ceiling side and floor side connecting members 40, 40. Good. This is convenient when adjusting the height at which the moving panel P is hung. Further, in the compression spring S, the movable seal members 21 and 31 are packed into the packings 21a and 3a.
Ceiling surface C, floor surface F with a very small difference within the elastic deformation range of 1a
It is not always necessary when the moving panel P can be installed so as to reach.

Other Embodiments A multi-start screw or a ball screw can be used for either one of the feed screw mechanisms 20 and 30. Since these screws can have a larger feed pitch than general screws, they are advantageous when the feed pitch of one of the feed screw mechanisms 20 and 30 is made significantly larger than the other, and further, At this time, the input shaft 11 does not become extremely heavy.

A mechanical play mechanism 50 can be provided in the middle of the connecting member 40 (FIG. 5). For example, a play mechanism 50 including an outer pipe 51 having a long hole 51a and a stopper pin 52 moving in the long hole 51a is provided in an intermediate portion of a main rod 41 for driving the movable seal member 21 on the ceiling side. Then, even if the main rod 41 is pushed, it is possible to prevent the operation thereof from being transmitted to the movable seal member 21 within the play range d3 of the stopper pin 52.

That is, with respect to the rotation operation of the input shaft 11, the movable seal member 21 on the ceiling side does not move for the first n2 rotations (6th rotation).
Only the movable seal member 31 on the floor moves. Therefore, even if there is a large dimensional difference that cannot be adjusted only by the difference in the feed pitch of the feed screw mechanisms 20, 30 between the ceiling side gap d1 and the floor side gap d2, the movable seal members 21, 31 Can be closed at almost the same time. The play mechanism 50
May use a spline shaft or the like.

The feed screw mechanisms 20 and 30 have a movable seal member 21,
As long as it is installed in the forward and backward direction of 31, the connecting members 40, 40
Can be arranged at any desired position (Fig. 7). The lead screw mechanisms 20 and 30 are horizontal members 4 on the ceiling side and the floor side, respectively.
It is attached to 2, 42. The feed screw mechanisms 20, 30 and the worm gear mechanism 10 rotate the output shaft 12 by the feed screw 23,
They are connected via the extension output shafts 12a, 12a which are transmitted to the 33. The sliders 24 and 34 are directly fixed to the horizontal members 42 and 42,
The casings 20a and 30a are omitted. With a simple structure, the same operation can be performed on the movable seal members 21 and 31.

The worm gear mechanism 10 includes a plurality of ceiling-side feed screw mechanisms 20, 20 ... and a plurality of floor-side feed screw mechanisms 30, 30 ... Simultaneously via the bevel gear mechanisms 60, 60 ..., The extension output shafts 12a, 12a. It can be driven (Fig. 8). The bevel gear mechanism 60 is provided with rotary shafts 61, 61 ... In three directions (solid lines in FIG. 9), interlocked with each other by three bevel gears 61a, 61a. By doing so, the output can be taken out from the remaining two-direction rotating shafts 61, 61. By rotating the worm gear mechanism 10, a large number of feed screw mechanisms 20, 20, ...
Since the 30, 30, ... Can be driven simultaneously, the long movable seal member 21 and the divided movable seal members 31, 31 can be operated at the same time.

Movable seal members 71, 71 on the wall side are arranged on the side end surface of the moving panel P, and can be driven by horizontal feed screw mechanisms 70, 70 connected to the worm gear mechanism 10 via the bevel gear mechanisms 60, 60. (Fig. 10). However, here
There are two transmission systems from the worm gear mechanism 10 to the respective movable seal members 21, 31, 71, and the movable seal members 21, 31, 71, 71 are driven by rotating the two worm gear mechanisms 10, 10. It is supposed to do. Also,
Floor-side and wall-side feed screw mechanisms 30, 70 and movable seal member 3
A compression spring S is interposed between the compression springs 1 and 71. The feed pitch of the feed screw (not shown) of each feed screw mechanism 70 in the horizontal direction may match the ceiling side or the floor side depending on the installation conditions of the moving panel P. Good. Further, it is not necessary to match any of them. This is extremely convenient because the movable seal members 21, 31, 71 in the three directions can be operated simultaneously. Needless to say, the two transmission systems may be combined into one system by the bevel gear mechanism 60. In this case, if the bevel gear mechanism 60 having the rotating shaft 61 in the fourth direction is used,
It is easy to add horizontal feed screw mechanism 70, etc.
(Two-dot chain line in the figure).

In the above description, the worm gear mechanism 10 has only to be able to combine its input / output shaft in a predetermined direction,
A general screw gear mechanism including a helical gear can be used.

Effects of the Invention As described above, according to the present invention, the feed screw mechanism on the ceiling side and the feed screw mechanism on the floor, which are connected to the screw gear mechanism, have different feed pitches. With respect to the rotation operation of the gear mechanism, the movement amount of the ceiling-side movable seal member that moves forward and backward by the former and the movement amount of the floor-side movable seal member that moves forward and backward by the latter can be different. Even when the gap between the panel and the ceiling surface or floor surface is significantly different, there is an excellent effect that both gaps can be blocked almost simultaneously in a short time.
