JP7755851B2 - Moving Wall - Google Patents

Description

The present invention relates to a large moving wall that can move along a running rail, and in particular to a moving wall that can maintain high soundproofing performance over a long period of time.

In multipurpose halls and other facilities, large movable walls (sometimes called "sliding walls" or "moving partitions") are used to divide the space into appropriate sizes. The movable walls are suspended from a running rail via runners and can slide along the rail.
The moving wall is provided with pressure contact members at the upper and lower ends of the panel body, which protrude outward from the panel body and press against the underside of the running rail and the floor, thereby fixing the moving wall and ensuring soundproofing. In addition, a pressure contact member may be provided at either the left or right end of the panel body, which may protrude outward from the panel body and press against the wall rail.

For example, Patent Documents 1 and 2 disclose a structure in which a gasket (soundproofing material) is placed between the panel body and the pressure-welded body for soundproofing purposes.

However, with the technology disclosed in the above patent document, the soundproofing material is always in contact with the pressure-contacting body, which means that if the soundproofing material is in strong contact with the pressure-contacting body, the pressure-contacting body will not move well, and if the contact is weak, the soundproofing performance will be poor and the soundproofing material will be prone to wear.

The present invention takes these problems into consideration and aims to provide a large-scale moving wall that can maintain high soundproofing performance over a long period of time.

The movable wall of the present invention is a movable wall that can move along a running rail and comprises a panel main body, two upper and lower pressure bodies that can be stored inside the panel main body so that they can be freely moved in and out, and a drive mechanism that presses the upper pressure body against the running rail and the lower pressure body against the floor surface, wherein when pressed together, the soundproofing material of the pressure bodies contacts the inner wall of the panel main body, and when the pressure is released, the soundproofing material moves away from the inner wall or contacts the inner wall with a relatively weaker force than when pressed together, and the pressure bodies comprise a first frame that moves in response to the driving force of the drive mechanism, and a second frame that holds the first frame and to which the soundproofing material is attached, wherein the second frame has a holding part that holds the first frame, and the holding part has an inclined surface, and when pressed together, the end of the first frame slides on the inclined surface, and an external force is applied to the holding part from the first frame, causing the second frame to assume an inclined position, and the soundproofing material attached to the second frame moves in a direction that contacts the inner wall .
The movable wall of the present invention is a movable wall that can move along a running rail and comprises a panel body, one of the pressure-receiving bodies on the right or left side that can be stored inside the panel body and can be freely moved in and out, and a drive mechanism that presses the pressure-receiving body against the wall rail. When pressed, the soundproofing material of the pressure-receiving body contacts the inner wall of the panel body, and when the pressure is released, the soundproofing material moves away from the inner wall or contacts the inner wall with a relatively weaker force than when pressed. The movable wall comprises a first frame that moves in response to the driving force of the drive mechanism, and a second frame that holds the first frame and to which the soundproofing material is attached. The second frame has a holding portion that holds the first frame, and the holding portion has an inclined surface. When pressed, the end of the first frame slides on the inclined surface, and an external force is applied to the holding portion from the first frame, causing the second frame to assume an inclined position, and the soundproofing material attached to the second frame moves in a direction that contacts the inner wall .

In the present invention, the soundproofing material of the press-fit body contacts the inner wall of the panel body when pressed, and when the press-fit is released, the soundproofing material separates from the inner wall or contacts the inner wall of the panel body with a relatively weaker force than when pressed. Therefore, the movement of the press-fit body can be made smoother compared to conventional cases where the soundproofing material is always in strong contact with the panel body.
Furthermore, when the first frame moves during pressure welding, the second frame moves in response to the external force of the first frame, and the soundproofing material comes into contact with the inner wall. The soundproofing material comes into strong contact with the panel body only when pressure welding is performed, and at other times it is separated from the panel body or comes into contact with it with relatively weak force. This prevents the conventional problem of the pressure welding body sliding against the panel body while in strong contact with it, which hinders its smooth movement and causes the soundproofing material to wear out quickly.

An embodiment of the moving wall of the present invention will be described.
As shown in Figures 1 to 3, the moving wall 1 is suspended from a traveling rail 3 via a runner 2, and can slide along the traveling rail 3. Reference numeral 6 in Figures 1 and 2 indicates the ceiling surface.

The moving wall 1 comprises a panel body 10, two upper and lower pressure contact bodies 20, and a drive mechanism (not shown). Multiple moving walls 1 are connected left and right to form a single large wall, and the moving wall 1 located at the far right (or left) end is equipped with a right (or left) pressure contact body 21 in addition to the upper and lower pressure contact bodies 20. Figure 1 shows the case where the right pressure contact body 21 is provided. The structure and operation of the upper, lower, and right pressure contact bodies 20, 21 are essentially the same, so the following explanation will mainly focus on the lower pressure contact body 20.

The structure of the panel body 10 is not particularly limited and can be any known structure, but in this embodiment, the rectangular outer frame 11 and its internal horizontal frames 12 are constructed from square pipes, gypsum board is used as the surface material 13, and glass wool 14 is filled inside. The top, bottom, left, and right edges are surrounded by frame members 15 with a U-shaped cross section made of metal such as aluminum. Other surface materials that can be used include calcium silicate board and plywood, and a covering material may be applied over the surface material.

2 and 3, the pressure contact bodies 20 are stored inside the panel main body 10, more specifically, inside the edge member 15, so that they can be freely moved in and out. An operator moves the moving wall 1 to a predetermined position and operates the drive mechanism to press and fix the upper pressure contact body 20 onto the running rail 3 and the lower pressure contact body 20 onto the floor surface 4. As will be explained in detail later, the pressure contact bodies 20 are equipped with soundproofing material 41, and when pressed, the soundproofing material 41 comes into contact with the inner wall of the panel main body 10, more specifically, the inner wall of the edge member 15, and when the pressure is released, the soundproofing material 41 moves away from the inner wall.
The structure of the drive mechanism may be any known one and is not particularly limited, but for example, when an operator inserts a handle into an operating hole on the surface or side of the panel body 10 and rotates it, the power is transmitted via gears, nuts, etc. to the shaft 22 extending in the vertical and rightward directions, causing the shaft 22 to rotate about its axis, and the pressure contact body 20 connected to the shaft 22 via gears, nuts, etc. moves up and down and left and right. A drive mechanism with a pantograph structure is also known.

As shown in FIG. 4, the pressure contact body 20 includes a first frame 30 and a second frame 40 .
The first frame 30 has a U-shape in vertical cross section that opens downward, and extends in the left-right direction with a length that is approximately the same as the width of the panel body 10. The first frame 30 moves in the up-down direction by receiving a driving force from a driving mechanism. Note that the shaft 22 of the driving mechanism is not shown in Figures 4 to 7.
The first frame 30 has a locking piece 31 on the top and a contact piece 32 on the bottom.
The second frame 40 is a plate-shaped member in a vertical cross section, and extends in the left-right direction with a length substantially equal to the width of the panel body 10. The second frame 40 includes a soundproofing material 41 and a holding portion .

The "soundproofing" in the soundproofing material 41 is a general term that includes "sound insulation" and "sound absorption.""Soundinsulation" means blocking sound transmitted through the air, and "sound absorption" means absorbing sound and preventing its reflection. Examples of sound insulation materials include rubber, and examples of sound absorption materials include urethane foam, but are not limited to these.
The soundproofing material 41 is attached to the upper part of the second frame 40 so that its end faces outward (toward the inner wall of the panel main body 10).

The holding portion 42 is provided to hold the first frame 30 .
Specifically, the upper holding portion 42a is a claw-shaped member provided on the upper portion of the second frame 40, and is attached so that its end hangs slightly inward. The upper holding portion 42 is designed to catch the locking piece 31 of the first frame 30.
The lower holding portion 42b is a concave member provided at the bottom of the second frame 40, and has an inclined surface 42c on its inner surface. The inclined surface 42c is inclined downward and outward. The contact piece 32 of the first frame 30 fits into the lower holding portion 42b.
In this way, the locking pieces 31 of the first frame 30 are caught on the upper holding portions 42 and the contact pieces 32 are fitted into the lower holding portions 42, so that the first frame 30 is held by the second frame 40.
Rubber legs 50 are attached to the lower part of the holding part 42, and when pressed, the legs 50 press against the floor surface 4, thereby fixing the moving wall 1. When pressed, the legs 50 of the upper pressing body 20 press against the traveling rail 3, and the legs 50 of the right pressing body 20 press against the wall rail.

Next, the operation of the pressure contact member 20 will be described.
As shown in Figure 4, when the operator rotates the handle of the drive mechanism while the pressure contact body 20 is stored inside the panel main body 10, the power is transmitted to the first frame 30, and the first frame 30 begins to descend. At this time, since the first frame 30 is held by the second frame 40, the second frame 40 also descends together with the first frame 30, and as shown in Figure 5, the legs 50 first come into contact with the floor surface 4, and the second frame 40 stops descending while remaining in an upright position.
After the legs 50 come into contact with the floor surface 4, the first frame 30 continues to descend, and the contact pieces 32 come into contact with the inclined surfaces 42c of the lower holding portions 42 as shown in FIG.

The contact piece 32 slides further downward on the inclined surface 42c, and at that time the inclined surface 42c receives an external force (reaction force) from the contact piece 32, and as shown in Figure 7, the external force causes the upper part of the second frame 40 to move outward (toward the inner wall of the panel main body 10), and the second frame 40 assumes an inclined position.
Since soundproofing material 41 is attached to the upper part of second frame 40, soundproofing material 41 comes into contact with the inner wall of panel body 10, more specifically, the inner wall of edge member 15. When contact piece 32 reaches the bottom of lower holding portion 42, the handle becomes heavy due to the reaction force, and at that point the operator stops operating the handle.
In this way, the soundproofing material 41 comes into contact with the inner wall of the panel body 10 when pressed together, so that transmission of sound from the front side to the back side of the panel body 10 can be suppressed.
Note that the soundproofing material 41 may be in contact with the inner wall of the panel main body 10 when the pressure connection is released as shown in Fig. 4. In this case, the soundproofing material 41 is in constant contact with the inner wall of the panel main body 10, but compared to when the pressure connection is released as shown in Fig. 7, the soundproofing material 41 comes into contact with the inner wall of the panel main body 10 with a relatively weaker force.

When the operator rotates the handle in the opposite direction to release the pressure, the first frame 30 begins to rise. The second frame 40 returns from the inclined position to an upright position, and the contact piece 32 separates from the inner wall of the panel body 10, continues to rise together with the first frame 30, and is finally stored inside the panel body 10.
As shown in Figure 3(b), the pressure-contact body 20 on the right side also comes into contact with the wall rail 5 by operating the handle, and the soundproofing material 41 comes into contact with the inner wall of the panel main body 10, thereby suppressing the transmission of sound from the front side to the back side of the panel main body 10.

This invention is a large-scale movable wall that can maintain high soundproofing performance over a long period of time, and has industrial applicability.
