A configurable, dismantlable display case system, with supports for promotional graphics, for use as a display cabinet, the constitution thereof being simple and entailing a reduced cost, and with the possibility of changing the configuration of its assembly and the promotional campaign thereon. The modular display system includes generally of a plastic shelving unit, with trays at different levels, linked at their corners by means of pillars of a generally triangular shape, which fit adjustedly into corresponding housings, one at each corner and on both sides of each tray; short profiles of a more reduced length than the pillar profiles, of a generally triangular shape with rounded corners which slot adjustedly into the corresponding housings of the tray; and non-slip ferrules inserted into the profile forming the leg at the area in contact with the floor; and assembly method.

A frame structure of aquaponic system assembled by module elements, comprising a base, at least a cultivating tank, a fix cover and a plurality of connecting members. Said elements of a frame structure are connected by the friction of elements through mortise-tenon joint and are easy for assembly and maintenance.

An improved shelf system often has differently configured shelves, at least some of which may receive attachments along a perimeter portions thereof. Those or others can provide bins for storing material as well internal to the shelves or along the perimeter portions.

Modular shelving comprising at least one shelf supported by at least one tube, wherein said shelf is coupled to said tube by means of a coupling element which is arranged externally in said tube and internally in a hole passing through the shelf, where each coupling element is divided lengthwise into two identical halves which are tongue and groove coupled together and, being coupled, can fit snugly into the hole of the shelf, whereby a tube supporting the shelf is fitted.

A butt-joining and engaging structure that allows to a pair of columns to be connected. The butt-joining and engaging structure has a seat body with a first connecting portion and a through hole, a stop part extends from an inner wall of the through hole toward the center of the through hole, a connecting member has a pair of ends defining a plug-in portion and a second connecting portion, and a position limiting part protrudes from the abutment surface of the connecting member. The first connecting portion is adapted to be affixed to one of the pair of columns. The second connecting portion is adapted to be secured to an end of the other column.

A supporting frame includes at least one supporting element, a base and a light-permeable pillar. The supporting element has a first through-hole. A cam is disposed in the supporting element and has a second through-hole and a turning portion. The second through-hole is disposed corresponding to the first through-hole. The base extends to form a sleeve. The light-permeable pillar passes through the first through-hole and the second through-hole and is inserted into the sleeve. The supporting element is capable of sliding along the light-permeable pillar. The turning portion is configured for pushing against an inner wall of the supporting element for fixing the supporting element on the light-permeable pillar.

A shelf includes at least one shelf post and a plurality of shelf floors, wherein the at least one shelf post includes at least one node element which is fixed and supported on at least one post profile by at least one pin which is inserted into a hollow chamber of the post profile and on which a corner of a shelf floor is held in a receptacle, wherein the receptable and the at least one pin are formed in one piece with the node element. As a result, the shelf post can be formed compactly and the shelf floors are stably supported during simple assembly.
