Description

Technology Field

[0001] The present invention relates to an indoor variable wall structure of a building. Background Technology

[0002] Recently, as the utilization of residential and office spaces has diversified and the demand for spatial reconfiguration driven by changes in users' lifestyles has rapidly increased, interest in variable walls—which allow indoor spaces to be freely divided or partitioned as needed, instead of fixed-structure walls—is growing.

[0003] Conventional variable walls or movable partitions have largely been implemented in sliding, folding, or simple combinations of these two methods. These conventional technologies have been primarily used to temporarily divide two or more zones in relatively large spaces, such as large offices, hotel banquet halls, and lecture halls.

[0004] However, since such conventional movable walls basically have a structure limited to movement on a single plane or simple folding, there was a problem in that it was structurally impossible to immediately form a closed space in the form of an independent room with completely shielded sides, or it required additional, very complex components.

[0005] In addition, conventional movable walls had limitations, such as having a structure that continuously occupies a significant portion of the indoor space even when not in use, or having a fixed installation location during construction, making it difficult to freely create enclosed spaces of the desired location or size.

[0006] In particular, the absence of a mechanism capable of creating a perfectly acoustically and spatially independent space by organically combining with the interior walls of existing buildings, going beyond simple visual shielding, has been pointed out as a fundamental drawback of conventional technology.

[0007] Therefore, there is a need to develop a new type of variable wall structure that can be compactly stored to occupy only a minimum amount of space when not in use, and when needed, can be rapidly moved to any position along a rail and then organically combined with the interior wall surface of a building through multi-stage pulling and folding movements to form a completely closed space.

[0010] Another objective of the present invention is to provide an indoor variable wall structure for a building that can maximize space utilization efficiency by minimizing the indoor space occupied by the walls, by adopting a multi-stage storage structure in which the second wall and the third wall are sequentially stored inside the first wall when not in use.

[0011] Another objective of the present invention is to provide an indoor variable wall structure for a building that ensures stable and smooth operational reliability by preventing play, shaking, and detachment that occur during the movement and withdrawal operations of the wall through the application of a slider having an elastic support structure and an anti-detachment block.

[0012] Another objective of the present invention is to provide an indoor variable wall structure for a building that is equipped with an extension on the third wall to completely shield the gap occurring between the end of the extended third wall and the inner wall surface of the building, and simultaneously firmly fix the entire wall module to the inner wall surface of the building through magnetic force coupling between a fixed magnet and a rail magnet and friction fixation by a grounding pad.

[0044] FIG. 1 is a plan view showing an indoor variable wall according to an embodiment of the present invention.

[0045] Referring to FIG. 1, an indoor variable wall (100) of a building according to an embodiment of the present invention (hereinafter referred to as 'indoor variable wall (100)') is a device installed on an inner wall surface (W) of a building to variably form a separate closed space partitioned within an indoor space.

[0046] The indoor variable wall (100) mainly includes a rail (1) and a wall module (2).

[0047] The rail (1) can be installed to extend horizontally along the inner wall surface (W) of the building.

[0048] The rail (1) can be installed on the upper or lower part of the inner wall surface (W), or on both the upper and lower parts, and provides a movement path so that the wall module (2) can slide stably along the inner wall surface (W).

[0049] The cross-sectional shape of the rail (1) may have a channel structure into which the first slider (211) and the fixing member (234B), which will be described later, are inserted and can be moved or fixed.

[0050] The rail (1) can be manufactured from a material with excellent strength and high durability, such as aluminum alloy or stainless steel, and minimizes friction through surface treatment to ensure smooth movement of the wall module (2).

[0051] The wall module (2) is slidably connected to the rail (1) and can variably form a closed space as it expands and folds.

[0052] The wall module (2) may include a first wall (21), a second wall (22), and a third wall (23).

[0053] The first wall (21) is slidably connected to the rail (1) and can move along the inner wall surface (W).

[0054] The second wall (22) is provided to be stored inside the first wall (21), and when pulled out to the outside of the first wall (21), it may be positioned parallel to the first wall (21) or bent in a right-angle direction.

[0055] The third wall (23) is provided to be stored inside the second wall (22), and when pulled out to the outside of the second wall (22), it may be positioned parallel to the second wall (22) or bent in a right direction, and the end may be positioned to face the inner wall surface (W).

[0056] In this way, the first wall (21), the second wall (22), and the third wall (23) are sequentially drawn out and bent in a right-angle direction, thereby quickly forming a completely closed space in the form of an independent room that utilizes the inner wall surface (W) as one side.

[0057] In addition, since the position of the wall module (2) can be freely moved along the rail (1), a closed space can be set at any location desired by the user, thereby significantly improving the flexibility and convenience of space utilization.

[0058] The first wall (21) may include a first slider (211), a first wall body (212), and a first guide rail (213).

[0059] The first slider (211) can be detachably coupled to the rail (1) and configured to slide along the longitudinal direction of the rail (1) inside the rail (1).

[0060] The first slider (211) is positioned at the end of the first wall body (212) and inserted into the interior of the rail (1), thereby providing a structure that suspends the entire first wall (21) on the rail (1) or supports it from below.

[0061] The detachable structure of the first slider (211) allows the first wall (21) to be easily separated from the rail (1) during installation and maintenance, thereby increasing the convenience of parts replacement or maintenance work.

[0062] The first wall body (212) is coupled to the first slider (211) and is positioned vertically with respect to the inner wall surface (W) in the indoor space, and a first storage space (212A) may be formed inside so as to accommodate the second wall (22).

[0063] The first wall body (212) may be formed in the shape of a hollow box, and the second wall (22) and the third wall (23) are sequentially stored in the first storage space (212A) inside, thereby minimizing space occupation when not in use.

[0064] The outer wall of the first wall body (212) can have insulation, sound-absorbing material, etc. built in to improve the sound insulation and thermal insulation performance of the enclosed space, and the surface finishing material can be applied in various ways according to the user's interior requirements.

[0065] The first wall body (212) may further include an opening / closing door (212B) and an entrance / exit opening (212C).

[0066] The opening / closing door (212B) may be positioned on one side of the first wall body (212) facing the interior space side with the first storage space (212A) as the center, and configured to be openable and closable.

[0067] The opening / closing door (212B) can be configured in a hinge type, a sliding type, etc., and when the wall module (2) is in a storage state, the opening / closing door (212B) can be closed to safely protect the second wall (22) inside the first storage space (212A) from external impact and foreign matter.

[0068] In addition, when the opening / closing door (212B) is opened, the second wall (22) can be pulled out, allowing the user to perform the closed space formation work more conveniently.

[0069] The entrance (212C) is positioned on the other side of the first wall body (212) facing the closed space side with the first storage space (212A) as the center, so as to connect the first storage space (212A) and the closed space.

[0070] The entrance opening (212C) functions as an opening through which the second wall (22) passes when it is pulled out from the first storage space (212A) toward the closed space, and can be formed with a size corresponding to the width and thickness of the second wall (22).

[0071] By having the entrance (212C) located on the closed space side, the second wall (22) can naturally extend into the interior of the closed space.

[0072] In this way, by arranging the opening / closing door (212B) and the entrance / exit (212C) on opposite sides of the first wall body (212), a storage protection function when not in use and a smooth extraction function when in use can be secured simultaneously.

[0073] The first guide rail (213) is received inside the first wall body (212) and installed on the inner side of the first wall body (212), and the second wall (22) can be slidably connected.

[0074] The first guide rail (213) may be installed extending along the longitudinal direction of the first wall body (212) on the inner upper surface and / or lower surface of the first storage space (212A), and the second slider (221), described later, is coupled to the first guide rail (213) to guide the linear movement of the second wall (22).

[0075] FIG. 2 is a drawing showing a first slider according to an embodiment of the present invention.

[0076] Referring to FIG. 2, the first slider (211) may include a first sliding body (211A), protruding blocks (211B), first sliding rollers (211C), and a block elastic support member (211D).

[0077] The first sliding body (211A) is positioned at the end of the first wall body (212) and can be inserted into the interior of the rail (1).

[0078] The first sliding body (211A) is formed in a shape corresponding to the internal cross-sectional shape of the rail (1), so that it can move stably along the longitudinal direction inside the rail (1).

[0079] A receiving space is formed inside the first sliding body (211A) to accommodate the protruding blocks (211B).

[0080] The protruding blocks (211B) are received inside the first sliding body (211A), with a portion protruding to the upper part of the first sliding body (211A) and another portion protruding to the lower part of the first sliding body (211A), and can be configured to slide vertically along the inner surface of the first sliding body (211A).

[0081] The protruding blocks (211B) can be divided into upper protruding blocks and lower protruding blocks, each protruding outwardly to the upper and lower sides of the first sliding body (211A) and positioned to contact the upper and lower inner surfaces of the rail (1).

[0082] The vertical sliding movement structure of the protruding blocks (211B) performs an automatic correction function that ensures the first sliding rollers (211C) can always be in close contact with the inner surface of the rail (1) even with changes in inner diameter due to manufacturing tolerances or wear of the rail (1).

[0083] The first sliding rollers (211C) are rotatably coupled to the protruding blocks (211B) and contact the inner surface of the rail (1), and when an external force is applied to the first wall (21), they can rotate along the inner surface of the rail (1) to transport the first wall (21).

[0084] The first sliding rollers (211C) can be configured in the form of bearing rollers with a low coefficient of friction, and by simultaneously supporting the upper and lower inner surfaces of the rail (1), they effectively suppress vertical shaking that occurs during the movement of the first wall (21).

[0085] The block elastic support member (211D) is positioned between the protruding blocks (211B) and elastically supports the protruding blocks (211B) toward the inner surface of the rail (1) so that the first sliding rollers (211C) can be pressed against the inner surface of the rail (1).

[0086] The block elastic support member (211D) may be composed of a coil spring, a leaf spring, or an elastic rubber member, and by elastically pressing the protruding blocks (211B) outward in the up and down direction, the first sliding rollers (211C) maintain a constant contact force with the inner surface of the rail (1).

[0087] As a result, any gaps or shaking that may occur during the sliding movement of the first wall (21) are fundamentally suppressed, thereby ensuring stable and smooth movement performance.

[0088] Referring to FIG. 1, the second wall (22) may include a second slider (221), a second wall body (222), and a second guide rail (223).

[0089] The second slider (221) is accommodated in the first storage space (212A) and can be slidably coupled to the first guide rail (213).

[0090] The second slider (221) moves linearly along the first guide rail (213) to perform the operation of pulling out or storing the second wall body (222) into or out of the first storage space (212A).

[0091] The second wall body (222) can be rotatably coupled to the second slider (221).

[0092] When the second wall body (222) is stored in the first storage space (212A), it can be folded to be positioned parallel to the second slider (221) and occupy the minimum space within the first storage space (212A).

[0093] When the second wall body (222) is pulled out to the outside of the first storage space (212A), it may be positioned parallel to the second slider (221) or bent in a right-angle direction.

[0094] The right-angle bending of the second wall body (222) is centered on the hinge connection with the second slider (221), and in the bent state, the second wall body (222) is positioned in a direction perpendicular to the first wall body (212) to form a side wall of the closed space.

[0095] Additionally, a second storage space (222A) may be formed inside the second wall body (222) so that the third wall (23) can be accommodated.

[0096] By adopting a structure in which the second wall body (222) is rotatably coupled to the second slider (221) in this manner, it is folded to minimize space occupation when stored, and folded at a right angle when pulled out to immediately form a side wall of a closed space, thereby achieving the effect of simultaneously achieving storage efficiency and space partitioning functions.

[0097] The second guide rail (223) is received inside the second wall body (222) and installed on the inner side of the second wall body (222), and the third wall (23) can be slidably connected.

[0098] The structure of the second guide rail (223) guides the linear movement of the third wall (23) on the same principle as the first guide rail (213) and is installed extending along the inner surface of the second storage space (222A).

[0099] FIG. 3 is a drawing showing a second slider according to an embodiment of the present invention.

[0100] Referring to FIG. 3, the second slider (221) may include a second sliding body (221A), a second sliding roller (221B), a first anti-detachment block (221C), and a first stopper (221D).

[0101] The second sliding body (221A) is accommodated in the first storage space (212A) and can be moved within the first storage space (212A).

[0102] The second sliding body (221A) is positioned adjacent to the side of the first guide rail (213) and serves as a bracket that supports the second wall body (222).

[0103] The second sliding roller (221B) is rotatably coupled to the second sliding body (221A) to support the upper and lower portions of the first guide rail (213), and when an external force is applied to the second sliding body (221A), it rotates along the outer surface of the first guide rail (213) to transport the second sliding body (221A).

[0104] The second sliding roller (221B) may include a second-1 roller (221B1) and a second-2 roller (221B2).

[0105] The second-1 roller (221B1) can move along the upper part of the first guide rail (213) in contact with the upper part of the first guide rail (213).

[0106] The second roller (221B2) can move along the lower portion of the first guide rail (213) in contact with the lower portion of the first guide rail (213).

[0107] The second-2 roller (221B2) is provided in multiple numbers and is positioned behind the second-1 roller (221B1) along the longitudinal direction of the first guide rail (213) to support the lower end of the first guide rail (213) at multiple points.

[0108] In this way, by providing multiple second-2 rollers (221B2) and distributing support at multiple points for the lower portion, the moment caused by the self-weight of the second wall body (222) can be effectively distributed to suppress sagging deformation.

[0109] The first anti-detachment block (221C) is coupled to the second sliding body (221A) and supports the lower end of the first guide rail (213), and also supports the lower surface and left and right sides of the first guide rail (213) to prevent the second sliding roller (221B) from detachment when the second sliding body (221A) moves.

[0110] The first anti-detachment block (221C) may have a channel structure in the shape of a 'C' or 'U' that surrounds the lower cross-section of the first guide rail (213), and simultaneously contacts the lower surface and the left and right sides of the first guide rail (213) to restrain the second sliding roller (221B) so that it does not detach in both the vertical and horizontal directions.

[0111] This prevents the second slider (221) from coming off or derailing during the withdrawal and storage operation of the second wall (22), thereby maintaining excellent operational reliability even during long-term use.

[0112] The first stopper (221D) is coupled to the second sliding body (221A), and when the second sliding body (221A) moves in one direction and the second wall body (222) is pulled out to the outside of the first wall body (212), it can be caught on the first catch (214) installed on the inner side of the first wall body (212) to restrict the pulling out of the second wall body (222).

[0113] The first stopper (221D) can be configured in the form of a protruding pin, a hook, etc., and ensures operational safety by mechanically limiting the second wall body (222) so that it does not exceed the designed maximum withdrawal length.

[0114] Referring to FIG. 1, the third wall (23) may include a third slider (231), a third wall body (232), and an extension (234).

[0115] The third slider (231) is accommodated in the second storage space (222A) and can be slidably coupled to the second guide rail (223).

[0116] The third slider (231) moves linearly along the second guide rail (223) to perform the operation of pulling out or storing the third wall body (232) into or out of the second storage space (222A).

[0117] The third wall body (232) can be rotatably coupled to the third slider (231).

[0118] When the third wall body (232) is stored in the second storage space (222A), it can be positioned parallel to the third slider (231) and maintained in a folded state.

[0119] When the third wall body (232) is pulled out to the outside of the second storage space (222A), it may be positioned parallel to the third slider (231) or bent at a right angle.

[0120] The third wall body (232) is bent at a right angle and positioned so that its end faces the inner wall surface (W), thereby forming the remaining wall surface of the closed space together with the first wall body (212) and the second wall body (222).

[0121] In addition, a third storage space (231A) is formed inside the third wall body (232) so that the extension part (234) can be stored.

[0122] The extension part (234) is accommodated in the third storage space (231A) and connected so as to be slidably movable, and is pulled out to the outside of the third wall body (232) to cover the gap between the inner wall surface (W) and the third wall body (232), and is connected to the rail (1) to fix the third wall body (232).

[0123] When the wall module (2) is fully deployed, a gap may occur between the end of the third wall body (232) and the inner wall surface (W) due to manufacturing tolerances or dimensional differences, but the extension part (234) completely covers this gap, thereby realizing a completely acoustically and spatially independent closed space.

[0124] In addition, by connecting the extension part (234) to the rail (1) and fixing the third wall body (232), the entire wall module (2) can be maintained in a state where it is firmly fixed to the inner wall surface (W), thereby achieving the effect of realizing an organic connection with the inner wall surface (W) of a building, which was impossible in the prior art.

[0125] FIG. 4 is a drawing showing a third slider according to an embodiment of the present invention.

[0126] Referring to FIG. 4, the third slider (231) may include a third sliding body (231A), a third sliding roller (231B), a second anti-detachment block (231C), and a second stopper (231D).

[0127] The third sliding body (231A) is accommodated in the second storage space (222A) and can be moved within the second storage space (222A).

[0128] The structure and function of the third sliding body (231A) are based on the same principle as the second sliding body (221A) described above, and are positioned adjacent to the side of the second guide rail (223).

[0129] The third sliding roller (231B) is rotatably coupled to the third sliding body (231A) to support the upper and lower portions of the second guide rail (223), and when an external force is applied to the third sliding body (231A), it rotates along the outer surface of the second guide rail (223) to transport the third sliding body (231A).

[0130] The third sliding roller (231B) may include the third-1 roller (231B1) and the third-2 roller (231B2).

[0131] The third-1 roller (231B1) can move along the upper part of the second guide rail (223) in contact with the upper part of the second guide rail (223).

[0132] The third-2 roller (231B2) can move along the lower part of the second guide rail (223) in contact with the lower part of the second guide rail (223).

[0133] The third-2 roller (231B2) is provided in multiple numbers and is positioned behind the third-1 roller (231B1) along the longitudinal direction of the second guide rail (223) to support the lower end of the second guide rail (223) at multiple points.

[0134] In this way, multiple third-2 rollers (231B2) distribute and support the lower portion of the second guide rail (223) at multiple points, thereby preventing sagging and load concentration caused by the self-weight of the third wall body (232) and ensuring stable withdrawal operation.

[0135] The second anti-detachment block (231C) is coupled to the third sliding body (231A) and supports the lower end of the second guide rail (223), and also supports the lower surface and left and right sides of the second guide rail (223) to prevent the third sliding roller (231B) from detachment when the third sliding body (231A) moves.

[0136] The second anti-detachment block (231C) supports the lower surface and left and right sides of the second guide rail (223) simultaneously on the same principle as the first anti-detachment block (221C), thereby preventing the third sliding roller (231B) from detachment in both vertical and horizontal directions.

[0137] This prevents detachment and derailment during the withdrawal and storage operation of the third wall (23), thereby ensuring operational reliability.

[0138] The second stopper (231D) is coupled to the third sliding body (231A), and when the third sliding body (231A) moves in one direction and the third wall body (232) is pulled out to the outside of the second wall body (222), it can be caught on the second catch (224) installed on the inner side of the second wall body (222) to restrict the pulling out of the third wall body (232).

[0139] The second stopper (231D) mechanically limits the maximum extension length of the third wall body (232) by the same principle as the first stopper (221D), thereby ensuring operational safety by preventing damage to parts and inability to operate due to excessive extension.

[0140] FIG. 5 is a drawing showing an extension part according to an embodiment of the present invention.

[0141] Referring to FIG. 5, the extension part (234) may include an extension body (234A) and a fixing member (234B).

[0142] The extension body (234A) is accommodated in the third storage space (231A), and when pulled out to the outside of the third storage space (231A), it comes into contact with the inner wall surface (W) to shield the gap between the inner wall surface (W) and the third wall body (232).

[0143] The extension body (234A) can be configured in the form of a sliding panel that can be extended in the longitudinal direction of the third wall body (232), and reliably covers the gap regardless of the distance difference between the third wall body (232) and the inner wall surface (W).

[0144] A seal member or a cushioning pad may be attached to the inner wall surface (W) contact surface of the extended body (234A) to absorb shocks that occur upon contact and to increase airtightness.

[0145] The fixing member (234B) is positioned at the end of the extension body (234A) and can be detachably coupled to the rail (1).

[0146] By connecting the fixing member (234B) to the rail (1), it performs the function of pulling and fixing the entire third wall body (232) toward the inner wall surface (W) while the extension part (234) is pulled out.

[0147] The detachable structure of the fixing member (234B) facilitates the formation and release of the closed space, and has the effect of simplifying the structure while ensuring that each function is reliably performed.

[0148] The fixing device (234B) may include a fixing device body (234B1), fixing blocks (234B2), an elastic member (234B3), grounding pads (234B4), and a fixing magnet (234B5).

[0149] The fixed body (234B1) is positioned at the end of the extension body (234A) and can be inserted into the interior of the rail (1).

[0150] The main body of the fixing member (234B1) is formed in a shape corresponding to the inner cross-section of the rail (1) so that it can be stably inserted into the rail (1).

[0151] The fixing blocks (234B2) are received inside the fixing body (234B1), with a portion protruding to the upper part of the fixing body (234B1) and another portion protruding to the lower part of the fixing body (234B1), and can be configured to slide vertically along the inner surface of the fixing body (234B1).

[0152] The vertical sliding movement structure of the fixed blocks (234B2) provides an automatic correction function that allows the grounding pads (234B4) to stably contact the inner surface of the rail (1) even with changes in the inner diameter of the rail (1).

[0153] The elastic member (234B3) is positioned between the fixed blocks (234B2) and elastically supports the fixed blocks (234B2) toward the inner surface of the rail (1), thereby allowing the fixed blocks (234B2) to be in close contact with the inner surface of the rail (1).

[0154] The elastic member (234B3) may be composed of a coil spring, a leaf spring, or a compression elastic body, and presses the fixed blocks (234B2) outward in the up and down direction with a constant elastic force so that the grounding pads (234B4) always remain in close contact with the inner surface of the rail (1).

[0155] The grounding pads (234B4) are installed at the ends of the fixed blocks (234B2) that contact the rail (1) and may be made of an elastic material that contacts the inner surface of the rail (1) to restrict the movement of the fixed blocks (234B2).

[0156] The grounding pads (234B4) can be manufactured from an elastic material such as silicone rubber or urethane rubber with a high coefficient of friction, and generate high frictional force while elastically pressing against the inner surface of the rail (1), thereby preventing the unauthorized movement of the main body of the fixture (234B1).

[0157] The elastic material properties of the grounding pads (234B4) also provide an additional effect of preventing scratching or damage to the inner surface of the rail (1) by absorbing the impact that occurs when the main body (234B1) of the fixture is inserted.

[0158] The fixed magnet (234B5) is positioned at the end of the fixed body (234B1), and when the fixed body (234B1) is inserted into the interior of the rail (1), it can be coupled to the rail magnet (11) installed on the inner surface of the rail (1) through magnetic force.

[0159] The magnetic force coupling between the stationary magnet (234B5) and the rail magnet (11) functions as a secondary fixing means that is added to the friction fixation of the grounding pads (234B4).

[0160] The fixed magnet (234B5) and the rail magnet (11) are arranged so that opposite polarities face each other, and magnetic force coupling is automatically formed the moment the fixed body (234B1) is inserted into the correct position within the rail (1), thereby providing a snap-in fixing effect in which the fixed member (234B) is fixed in the correct position without any separate operation by the user.

[0161] In this way, a dual fixing mechanism is implemented in which pressure contact by the elastic member (234B3) and friction fixation by the grounding pads (234B4) provide primary fixing force, and magnetic force coupling between the fixing magnet (234B5) and the rail magnet (11) provides secondary fixing force.

[0162] As a result, even if external force or vibration occurs while using the enclosed space, the wall module (2) can be stably maintained in a state where it is firmly fixed to the inner wall surface (W).

[0163] As described above, according to an embodiment of the present invention, a wall module (2) can be freely moved to any position along a rail (1) installed on an inner wall surface (W), and then the first wall (21), the second wall (22), and the third wall (23) can be sequentially pulled out and bent in a right-angle direction to quickly form a completely closed space in the form of an independent room. This ensures high flexibility in space utilization, allowing the location, size, and use of the space to be freely set according to the user's needs.

[0164] In addition, by a multi-stage storage structure in which the second wall (22) and the third wall (23) are sequentially stored inside the first wall (21), the indoor area occupied by the indoor variable wall (100) when not in use is significantly reduced, thereby maximizing space efficiency.

[0165] In addition, by means of a first slider (211) structure with a block elastic support member (211D), a second slider (221) having a plurality of second-2 rollers (221B2) and a first anti-detachment block (221C), and a third slider (231) having a plurality of third-2 rollers (231B2) and a second anti-detachment block (231C), play, shaking, and detachment are fundamentally prevented during the movement and withdrawal operation of each wall, thereby maintaining excellent operational reliability and durability even in a repeated use environment.

[0166] In addition, the extension body (234A) of the extension part (234) completely seals the gap between the third wall body (232) and the inner wall surface (W), and the entire wall module (2) is firmly fixed to the inner wall surface (W) by the double fixing mechanism of the fixing device (234B), thereby realizing an organic connection with the inner wall surface (W) of the building that was impossible in the prior art, and realizing a completely acoustically and spatially independent closed space.

[0167] In addition, by providing an opening / closing door (212B) and an access opening (212C) on opposite sides of the first wall body (212), storage protection of the second wall (22) when not in use and a smooth extraction function when in use are simultaneously secured, thereby greatly improving the convenience of use of the indoor variable wall (100).
