The present disclosure provides systems and methods for assembling a device while maintaining the aesthetic appearance and structural integrity of a visible surface of the device. In one or more implementations of the invention, a system includes a first assembly piece with an assembly region that comprises an opening defined by first and second connecting elements. The system further includes a second assembly piece and a fastening assembly, where a portion of the second assembly piece is shaped to fit within the assembly region opening and the fastening assembly spans the first and second connecting elements to secure the first assembly piece to the second assembly piece, and tightening of the fastening assembly causes the second connecting element to deform, pressing a surface of the second assembly piece against an adjacent surface of the first connecting element and retaining a substantially even visible surface of the device.

The present invention is directed to a bed frame designed for quick assembly. In an exemplary embodiment, the invention may comprise a wire lattice that forms the support surface for a mattress and, if necessary, box springs. The wire lattice can be secured to a perimeter frame using brackets which hook onto the lattice and also attach to the sides of the frame. The bed frame may include vertical supports or legs that can be quickly attached to the frame. Each leg may include an attachment plate and a catch extending above the attachment plate. The leg can be secured to the bed frame by sliding the attachment plate into a receiver attached to the bed frame. As the attachment plate is being inserted, the catch may engage a series of corrugations formed in the receiver. The catch may press against a corrugation to lock the leg into the receiver.

A frame corner member includes an elongated hollow extrusion having a central corner portion and two leg portions extending from the central portion. Each leg portion includes an inner side wall spaced from and parallel to an outer side wall, and merging with the central portion. An outer end wall joins the inner and outer side walls, which each include an inner surface facing the inner surface of the other side wall. An opening through the outer end wall defines a space between the inner and outer side walls adjacent one end of the extrusion for receiving one end of one of frame side members and end members. At least one of the inner surfaces in the space has discrete surface features adapted to grip and retain the one end of one of the side members and end members in the space when received through the opening.

A mattress foundation includes: a head end panel assembly; a foot end panel assembly; a left side panel assembly; and a right side panel assembly, all slidably attaching to each other using sliding mechanisms. At least one of the sliding mechanisms includes an elongated slot and an elongated protruding element that fits within the elongated slot. A horizontal cross-section of the elongated slot and/or the elongated protruding element includes thin elongated flexible arms, attached at their proximal ends to a common surface, but otherwise extending away from such common surface and separated from each other. When viewed from the horizontal cross-section, the average thickness of the thin elongated flexible arms is substantially less than the length of the thin elongated flexible arms.

An attachment assembly for use with furniture and other articles. The attachment assembly includes a connector assembly that is configured to engage with a rail. The connector assembly includes a first, fixed protrusion, a lever, a second protrusion extending from the lever, and a third protrusion positioned between the first protrusion and the second protrusion. The rail includes a lip and a cutout in the lip that is sized to receive the third protrusion. The rail is configured to retain the connector assembly. Pivoting the lever when the connector assembly is positioned within the rail is configured to cause the second protrusion to bear against a bottom surface of the rail, such that the first protrusion and the second protrusion frictionally engage the bottom surface of the rail and the third protrusion frictionally engages the lip to fixedly hold the connector assembly.
