A display case has a first display case portion with walls configured so that each wall of a plurality of first fixed walls has a coupling edge arranged at the same coupling framework between the first portion and a second portion of the display case. The coupling edges of the first fixed walls are coplanar to one another and at least two of the first fixed walls are adjacent to each other and fastened together through gluing along a corner substantially perpendicular to the plane of the coupling edges. A groove is formed longitudinally on the coupling edge of each of the first fixed walls, the grooves of the first fixed walls jointly defining a channel along the coupling framework; a hoop cable is housed in the channel, closed on itself. The hoop cable contributes to keeping the walls coupled together at the coupling framework, ensuring that the walls stay in position even in the case in which the gluing with which the first fixed walls are fastened together partially or even totally gives way.

A set of panels includes a first panel having a first main plane and a second panel having a second main plane. The panels are provided with a mechanical locking device for locking a first edge of the first panel to a second edge of the second panel. The mechanical locking device includes an edge groove at the first edge, wherein an edge tongue of the second edge is insertable into the edge groove. A flexible tongue is arranged in an insertion groove provided in the edge section groove, and cooperates with a tongue groove provided at the edge section of the second panel. The first and the second panels are locked at a junction plane which is extending between the first main plane and the second main plane. The first edge comprises an edge tongue that extends from the junction plane.

A wooden guitar cabinet features a door equipped with one or more interior channels that allow the interior of the door to be in contact with the air in the interior of the cabinet, thereby keeping the interior of the door at the same level of humidity as the interior of the cabinet. This allows for the interior of the cabinet to be maintained at the optimal humidity levels for storing guitars while minimizing the risk of unsightly warping in the cabinet doors. The cabinet may be optionally equipped with a locking mechanism to prevent guitars from falling off shelves in the case of movement.

A truss support system is disclosed. The system is comprised of a plurality of tubular truss sections configured for attachment to each other. Each of the sections has a plurality of polygonal shaped access slots surrounded by a plurality of bolt holes along each of its peripheral sides and on end-plates at each end of the truss sections. The end-plates of the system have additional bolt holes around the access slot compared to the number of bolts surrounding the access slots on the peripheral sides to provide for increased hold between end-to-end connections of truss sections. The truss sections of the system may be hinged together to compensate for uneven ground or for increased load supported.

A storage unit for attachment to a door or similar structure is provided. The storage unit can be configured for holding shoes or any other suitably desired items. The storage unit can include a frame portion having two vertical supports and a plurality of horizontal cross supports extending perpendicularly from and between the two vertical supports. The storage unit can further include a liner portion constructed from fabric, plastic or other suitable material. The liner portion can be configured for connection to the frame portion and can include a plurality of shelving supports that can be attached to the plurality of horizontal cross supports in order to create a series of angled shelves along the height of the frame portion.
