The invention relates to a structural system (2) for the modular construction of shelves (2), comprising a set of elongate vertical supports (3), a set of frames (4) and a set of connectors (7). The vertical supports (3) each have at least one axially extending row of holes (31). The frames (4) each have four struts (42, 43), of which two are connected to one another via a mounting corner piece (41). The connectors (7) are each designed to be introduced into a hole (311) of one of the vertical supports (3) and secured to one of the mounting corner pieces (41) of one of the frames (4). The structural system (2) is designed such that, in an assembled state, at least one frame (4) of the set of frames (4) is secured by its mounting corner pieces (41) to four vertical supports (3) via a relevant connector (7), two respective neighboring vertical supports (3) that are connected to one another via one of the struts (42, 43) of the at least one frame (4) define a support plane (6), and the four struts (42, 43) of the at least one frame (4) lie outside the support planes (6) defined by the four vertical supports (3) connected to the frame.

A shelf support includes: a generally planar main body with front and rear faces, the main body further having upper and lower openings with a cross-beam therebetween; a support flange extending generally perpendicularly from the front face; a mounting dowel extending generally perpendicularly from the rear face; a capturing finger mounted at an upper edge of the upper opening, the capturing finger extending forwardly and downwardly at a first oblique angle to the front face; and a centering finger extending forwardly and downwardly from the cross-beam at a second oblique angle to the front face.

A shelving system comprising at least one back panel and at least one block element, the back panel comprises a substantially planar surface, and where the at least one block element is mounted on the back panel, wherein the back panel comprises at least two areas, a first area of the at least one back panel comprising protrusions; the protrusions being mutually identical and positioned on the planar surface in grid points of a regular two dimensional grid; and a second area of the at least one back panel comprises the at least one block element, the block element extending in a distance corresponding to one or multiple of a standard module size in a plane parallel to the planar surface of the back panel in two mutually perpendicular directions defined by grid points of a regular two dimensional grid.

A collapsible measuring and cutting craft table enables cutting, measuring, and stowing fabric and craft materials from a foldable, height-adjustable, and mobile work surface. The craft table comprises a large, flat work surface having a center panel and two hingedly attached drop leaf panels that fold down for storage. Center support members support the center panel in a horizontal position at the desired working height. Two center support members supports the center panel of the work surface. The outer support members pivot outwardly to a support position to support the drop leaf panels. The outer support members pivot inwardly to a collapsed position to fold the drop leaf panels down perpendicularly relative to the center panel. The center support members telescopically adjust in length to height adjust the work surface. The support members terminates at wheels for mobility. Meshed baskets slide along rails that run between the center support members.

A combined storage shelf is provided, including column combinations, connection and combination fasteners, beam structures, and storage layers. The column combinations include assembly holes. A snap-fit portion of a first connection and combination fastener is snapped to an assembly hole, to fix the first connection and combination fastener to the column combination. The engagement structure of the second connection and combination fastener corresponds to the engagement structure of the first connection and combination fastener, so that the first connection and combination fastener and the second connection and combination fastener are assembled together.

A modular rack assembly includes upright support legs, two first shelf units, and a second shelf unit. Each upright support leg has two spaced-apart first hole units, and a plurality of spaced-apart second holes disposed between the first hole units. The first shelf units are connected to the upright support legs through the first hole units. The second shelf unit is engaged to the second holes of the upright support legs which are at the same height, and includes a second shelf plate formed with insertion holes, and supporting members that are engaged to the second holes at the same height and that are inserted into the insertion holes to support the second shelf plate.
