A shelf frame for a rack of shelves includes an elongated body; a ledge extending perpendicularly from a bottom edge of the elongated body, the ledge having a width equal to a height of the elongated body; an elongated enhancement disposed along a top edge of the elongated body, the enhancement being bent toward the ledge; two upright extensions disposed at two ends of the elongated body respectively; and a plurality of fasteners disposed in each of the two upright extensions. The two upright extensions and the elongated body are on the same plane. Each of the two upright extensions has a length equal to twice of the height of the elongated body.

A collapsible hanging shelf may include a plurality of shelf members and a hanging member. A shelf member includes more than one parallel placed connecting units and a shelf. A connecting unit include one pair of crossing bars and a control bar that connecting a shelf and one of the pair bar. A shelf member connected with at least two connecting units at the points of one end of the control bar and the cross point of crossing bars. Each shelf is placed with other shelf in a vertically parallel manner. Once the hanging shelf is hung on the door, it can be pulled down by gravity and stopped at a fully extended position without applying any external forces. When it is taken off from the door and put it on the ground, the shelf can be quickly collapsed into a space saving position under the control of gravity.

The invention is directed to a corner retention clip system for supporting the front two corners of a shelf in a shelving system. Each corner retention clip includes a generally horizontal support panel, a channel connected to the support panel for receiving a front lip of a shelf of the shelving display and a side wall connector for connecting the clip to a side wall of the shelving display.

A desk system including desktop, legs, and foot elements is presented. Each leg is rotatably attached at one end to the desktop and attached at another end to one foot element which is also rotatable. The system is disposed in a stowed configuration when legs and foot elements are substantially parallel to the desktop and legs are disposed between and substantially parallel to foot elements. The system is disposed in an upright configuration when legs are substantially perpendicular to the desktop and each leg is substantially perpendicular to one foot element. The system is configured from stowed to upright by separately rotating legs about a minor axis in opposite directions away from one another and by separately rotating foot elements about a major axis in opposite directions toward one another. The system is configured from upright to stowed by separately rotating foot elements about the major axis in opposite directions away from one another and by separately rotating legs about the minor axis in opposite directions toward one another.

A shelf peg assembly has a peg member and securing clip, the peg member having a peg for inserting into a cabinet and a shelf receiving portion, and the securing clip having an aperture for receiving the peg from the peg member, a top edge for abutting the shelf receiving portion, and a sidewall for abutting the side of the shelf receiving portion and securing the outer edge of the shelf. In one method of use, three shelf peg assemblies support a shelf in a cabinet having only two walls.

A modular shelving system with a series of shelves, shelf-support brackets, bracket attachment disks, and hinge-pins. The support brackets are hingable. The support disks each include a series of apertures for allowing the disk to be fastened to a wall or stud. The shelf support brackets include shelf-receiving slots. The hinge-pin is threaded to be screwed into the bracket-receiving disks. The shelves are inserted into the shelf-receiving slots in the shelf-support brackets to create a custom multipurpose shelf design, including for climbing animals such as cats.

A shelf frame for a rack of shelves includes an elongated body; a ledge sticking inward from the elongated body and being perpendicular to the elongated body, the ledge having a width equal to that of the elongated body; an elongated enhancement disposed along an edge of the elongated body and being distal from the ledge, the enhancement being bent toward the ledge; two upright extensions disposed at two ends of the elongated body respectively; and a plurality of fasteners disposed at the extensions opposite to the ledge. The extensions and the elongated body are on the same plane and are parallel to each other. The extension has a length equal to twice of the width of the elongated body.

A rack has a left support and a right support. Each support has at least one set of two brackets that are aligned with each other and with the one set of two brackets at the other support, with each bracket including a side wall and a bottom wall that are oriented at 90 degrees from each other, with the bottom wall having at least one hole. The rack also includes at least one shelf, with each shelf having an enclosing frame member that has two opposing first sides connected by two opposing second sides to define four corners, with each first side having a bottom surface, and a hole in the bottom surface. Each corner of each shelf is secured to one bracket by positioning the first side on the bottom wall of the one bracket, and inserting a screw through the at least one hole in the bottom wall and into the hole in the bottom surface of the first side.
