Description

[Technical Field]

[0001] The present invention relates to a large-sized moving wall that can move along a traveling rail, and in particular to a moving wall that can maintain high soundproofing performance for a long period of time. [Background technology]

[0002] 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.

[0003] For example, Patent Documents 1 and 2 disclose a structure in which a packing (soundproofing material) is placed between the panel body and the pressure-contact body for the purpose of soundproofing. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 6-221061 [Patent Document 2] Utility Model Registration No. 3026036 Summary of the Invention [Problem to be solved by the invention]

[0005] However, in the technology disclosed in the above patent document, the soundproofing material is always in contact with the pressure-contacting body, so if the soundproofing material is in strong contact with the pressure-contacting body, the movement of the pressure-contacting body becomes poor, and if the contact is weak, the soundproofing properties become poor, and the soundproofing material is easily worn out.

[0006] In consideration of such problems, the present invention aims to provide a large-scale moving wall that can maintain high soundproofing performance for a long period of time. [Means for solving the problem]

[0007] The moving wall of the present invention is a moving wall that can move along a traveling rail, and is provided with a panel body, two pressing bodies, an upper and a lower, that are stored in the panel body so as to be freely retractable, and a drive mechanism that presses the upper pressing body against the traveling rail and the lower pressing body against the floor surface, and when pressed, the soundproofing material of the pressing body comes into contact with the inner wall of the panel body, and when the pressure is released, the soundproofing material moves away from the inner wall or moves with a force that is relatively weaker than when pressed. the inner wall Contact The press-fit body 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 having a holding portion that holds the first frame, the holding portion having an inclined surface, and an end portion of the first frame sliding on the inclined surface as the first frame moves during press-fitting, whereby an external force is applied from the first frame to the holding portion, the second frame assumes an inclined position, and the soundproofing material attached to the second frame moves in a direction that contacts the inner wall. It is characterized by: The moving wall of the present invention is a moving wall that can move along a traveling rail, and is provided with a panel body, one of the pressing bodies on the right or left side that is stored inside the panel body so as to be freely retracted, and a drive mechanism that presses the pressing body against the wall rail, and when the pressing is performed, the soundproofing material of the pressing body contacts the inner wall of the panel body, and when the pressing is released, the soundproofing material separates from the inner wall or moves with a force that is relatively weaker than when the pressing is performed. the inner wall Contact The press-fit body 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 having a holding portion that holds the first frame, the holding portion having an inclined surface, and an end portion of the first frame sliding on the inclined surface as the first frame moves during press-fitting, whereby an external force is applied from the first frame to the holding portion, the second frame assumes an inclined position, and the soundproofing material attached to the second frame moves in a direction that contacts the inner wall. It is characterized by: [Effects of the Invention]

[0008] 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 panel is pressed against the panel, the first frame moves, and the second frame moves in response to the external force of the first frame, causing the soundproofing material to come into contact with the inner wall. The soundproofing material comes into strong contact with the panel body only when the panel is pressed against the panel, 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-contacting body sliding against the panel body while in strong contact with it, which can hinder its smooth movement and cause the soundproofing material to wear out quickly.

DETAILED DESCRIPTION OF THE INVENTION

[0010] An embodiment of the moving wall of the present invention will be described. As shown in Figures 1 to 3, a moving wall 1 is suspended from a traveling rail 3 via a runner 2, and can be slid along the traveling rail 3. Reference numeral 6 in Figures 1 and 2 indicates the ceiling surface.

[0011] The moving wall 1 comprises a panel body 10, two upper and lower pressure contact bodies 20, and a drive mechanism (not shown). In addition, a plurality of moving walls 1 are connected in the left-right direction to be used as a single large wall, and one moving wall 1 located at the right end (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 a case where the pressure contact body 21 is provided on the right end. The structures and operations of the upper, lower, and right pressure contact bodies 20, 21 are almost the same, so the following description will mainly focus on the lower pressure contact body 20.

[0012] The structure of the panel body 10 is not particularly limited and may be any known one, but in this embodiment, a rectangular outer frame 11 and its internal horizontal frames 12 are made of 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 made of a metal such as aluminum and having a U-shaped cross section. Other surface materials that can be used include calcium silicate board and plywood, and a covering material may be applied on top of the surface material.

[0013] 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 turns it, the power is transmitted to the shaft 22 extending in the vertical and right directions via a gear, nut, etc., causing the shaft 22 to rotate about its axis, and the pressure contact body 20 connected to the shaft 22 via a gear, nut, etc. moves up and down and left and right. A drive mechanism with a pantograph structure is also known.

[0014] 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 main 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 .

[0015] The "soundproofing" in the soundproofing material 41 is a general term that includes "sound insulation" and "sound absorption." "Sound insulation" 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).

[0016] 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.

[0017] 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.

[0018] 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 (towards 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.

[0019] 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.
