A system for enhancing sound includes a structure defining a first portion of an oblong enclosure that forms an approximated double ellipse profile and positioned between a first area proximate a first speaker driver and a second area proximate the listener, the first portion of the oblong enclosure forming a first part of the approximated double ellipse profile; and a second portion of the oblong enclosure that forms the approximated double ellipse profile and positioned between a third area proximate a second speaker driver and a fourth area proximate the listener, the second portion of the oblong enclosure forming a second part of the approximated double ellipse profile. The first portion and the second portion are shaped such that sound emitted from the first speaker driver and the second speaker driver is reflected and focused toward the listener.

A device (1) for storage and use of wall elements (2) is disclosed. The device (1) comprises a receptacle (4) for the plurality of wall elements (2). The receptacle (4) can comprise at least one construction element (200) which holds the bottom (6) and the ceiling (7). According to an embodiment, the construction element (200) comprises two side walls. The side walls (5) connect the bottom (6) and the ceiling (7) of the receptacle (4). A locking mechanism (10) ensures that the wall elements (2) in the receptacle (4) cannot be removed in an unauthorized manner.

The invention is a track system for a retractable wall. The track system includes rigid outer guide tracks and flexible inner track inserts that are connected to the guide tracks by means of flanges located on both. The flexible inserts include a channel that engages with a side edge of a retractable wall, holding the wall in place. The flexible nature of the track inserts allows the inserts to bend, which in turn allows the retractable wall to flex when force is exerted on the retractable wall without breaking the tracks or tearing the wall. When excessive force is applied, the channel of the flexible insert, the walls of which are thicker than the rest of the flexible insert, bend open, so that the side edge of the retractable wall disengages from the channel by means of an opening in the channel.

Embodiments are directed to a hide screen for surveillance operations in urban environments. The hide screen may include a netting panel, a plurality of sleeves, and a plurality of frame poles. One or more of the sleeves may be coupled to the netting panel. The frame poles may be insertable into the sleeves to tension the netting panel.

The invention relates to a partition wall which comprises a wall element and a stand device, wherein the wall element comprises a multiplicity of tubular bodies, each having a cavity, which are vertically aligned in the room. The wall element herein comprises spacer webs, wherein one of the spacer webs is in each case disposed between neighbouring tubular bodies of the wall element in such a manner that the tubular bodies are aligned so as to be mutually parallel and mutually spaced apart.

A privacy apparatus includes one or more substantially cork panels. Each panel can be configured to provide visual and/or sound privacy for a certain work space. The panel can be supported on a floor via one or more base elements and/or may be reinforced in rigidity and/or strength via one or more supports. Some embodiments of the apparatus can include a first panel and a second panel attached together via one or more supports press fit within openings defined in rear faces of the panels.

A building unit is provided and includes a plurality of modular display panels and a plurality of modular display panel connectors. The plurality of modular display panels is positioned adjacent to each other in a grid shape array and extending between a display support structure having a plurality of interconnecting poles. The plurality of modular display panel connectors not in contact with the display support structure and connecting the plurality of modular display panels from a rear planar surface side of the plurality of modular display panels. Each modular panel connector is positioned along the rear planar surface side of the plurality of modular display panels and includes a plurality of fasteners securing the plurality of modular display panels in the grid shape array.

A carriage is disclosed for moveably supporting an acoustical panel. The carriage comprises a frame having rolling members for movably for supporting the acoustical panel. A first and a second pair of support legs extend angularly from the frame for enabling a plurality of carriages to orientate acoustical panels in a linear or angular relationship. Each of the unique acoustical panels provides sound absorption as well inhibiting sound transmission.

According to the present invention, provided is a prefabricated booth comprising: a frame in which a plurality of horizontal frames and a plurality of vertical frames coupled to the plurality of horizontal frames are three-dimensionally coupled to each other so as to form a square-shaped frame structure; a plurality of connection pieces, each of which both sides are respectively coupled to the inner sides of the frames vertically intersecting to be adjacent to each other; first profiles respectively arranged at the outer sides of the upper and lower horizontal frames of the square frame structure; second profiles erectly arranged to correspond to the vertical frame at the corner side of the square frame structure; and a bracket comprising a center part fastened to each connection piece, a first extension part extended to one side of the center part and fixing the first profile, and a second extension part extended to the other side of the center part and fixing the second profile.
