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 structure has a frame member, a layer member and at least one reinforcement board. An outer surface of the frame member has a plurality of parallel ribs and an inner surface of frame member has a contacting face between each two ribs. An upper end and a lower end of the frame member respectively has an upper portion and a lower portion parallel with each other. A lower surface of the upper portion has at least one protruding rib. The lower portion is smaller than the upper portion. The layer member is assembled in the frame member and overlaps the upper portion of the frame member. The reinforcement board has a length equal and parallel to two opposite sides of the frame member and secured to the other two opposite side of the frame member.

A combination shelf includes at least four column units, at least two storage layers, and multiple clips. The column unit consists of two parallel, vertical poles on the left and right, and multiple connections connecting the left and right vertical poles. The clip has a vertical groove with a wing located on both sides at the lower halves of the front and rear ends of the groove opening. The grooves of the clips can be embedded by the vertical poles. The front and rear ends of both sides of the storage layer each offers an outward-opening U-shaped fastener. The front and rear edges of the lower half of the fastener each has a top pusher. The fasteners of the storage layer can each cover the exterior of the clips of the column units. The inner faces of the two top pushers each presses the two wings. By fitting together the corresponding bevels of the top pushers and the two wings, the clips and the fasteners press each other and therefore clamping the vertical pole.

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 shelving system formed by a plurality of vertical posts and horizontal traverses held together through frictional engagement. Disposed between each lateral pair of posts is at least one traverse which includes a male frictional engagement member configured to engage with a removable female frictional engagement member disposed on each post. The post and traverse engage with each other so as to create a proportional or supportive reaction force in response to any shear force applied to the shelving system. Each of the female frictional engagement members has a tapered edge which forms a closely fitted coupling between the post and each traverse. Each of the female frictional engagement members may be selectively disposed in one of a plurality of positions along the height of each vertical post. The shelving system further includes top and bottom connectors, both of which also frictionally engage with the vertical posts.

A connection device is disclosed for installing a shelf or a shelf frame on a vertical support to construct a shelving unit The connection device includes a hanger component and a bracket. The hanger component is equipped with a main body designed to be suspended from the vertical support such that an engagement portion engages behind a perforation of the vertical support and a support portion is arranged outside of the perforation. The bracket includes a housing portion designed to rest against the vertical support and a cavity shaped to receive the support portion of the main body of the hanger component. The bracket includes a clamping mechanism for clamping the housing portion of the bracket together with the vertical support when the cavity of the housing portion receives the support portion, and the main body of the hanger component is suspended from the perforation of the vertical support.

A combined storage shelf, 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.

A coupling member (1) includes a pair of support members (11a, 11b) that are linked at one end so that an opening is formed at the opposite end, and the back sides thereof are situated opposite to each other, and a pair of engagement holes (12a, 12b) that are respectively formed in the support members (11a, 11b) in the thickness direction so as to extend from the back sides, and are situated opposite to each other, the outer side (a to d) of each of the support members (11a, 11b) forming a tapered surface that gradually slopes outward in the downward direction. An assembly shelf utilizes the coupling member (1). The assembly shelf utilizes an L-shaped angle, and is configured so that a shelf board member is not provided with a protrusion, a tool is unnecessary during assembly, and a middle shelf board can be removed conditionally.
