摘要： A tamper resistant attachment apparatus for attaching a backrest to a chair frame. A flap is foldably coupled to an edge of a chair backrest. The flap is foldable over onto the backrest into a folded position. The flap has a channel that fits around a frame of a chair when the flap is in the folded position. At least one aperture that extends through the flap can receive a corresponding pin that is coupled to the backrest when the flap is in the folded position. The at least one pin is deformable to secure the flap and backrest around the chair frame when the flap is in the folded position.

摘要： An upholstered folding chair includes a chair frame, a base member permanently attached to the frame, and an upholstered insert configured to slide into and removably interlock with either the base member or the chair frame. The base member includes a retaining rim, which covers and protects at least some of the edges of the upholstered insert, and the base member and upholstered insert may have interlocking members which become hidden between the base and insert when the two are interlocked together. The base can be either a back base for receiving and supporting an upholstered chair back insert, or a seat base for receiving and supporting an upholstered chair seat insert.

摘要： A joint between a leg and an elevated platform includes a tapered receptacle with straight widening walls coupled to one of either the leg or the platform. A mating insert is coupled to the other of the leg or the platform and is selectively insertable into the tapered receptacle. The mating insert has straight narrowing walls that are engageable with the widening walls of the tapered receptacle. The weight of the platform pushes the insert into the receptacle such that the narrowing walls of the insert engage the widening walls of the tapered receptacle.

摘要： A folding chair has a rigid support frame with a curved spline profile, and a seat and rear legs which fold into a closed position and substantially collapse within a volume defined by the support frame to maximize stacking density, and to increase stability with the curved spline profiles nesting within one another. The support frame has first and second rigid side support members, each with an upper back support portion and extending forwardly to form front leg portions. The back support portion and the front leg portions are integrally and rigidly connected to advantageously form a curved spline profile. A seat is pivotally coupled to the support frame, or to and between the first and second support members. A majority of the seat advantageously collapses to a folded position within a volume defined between the first and second rigid side support members. Rear legs are pivotally coupled to the support frame, or to the respective first and second support members. A majority of the rear legs advantageously collapses to a folded position within the volume defined by the support frame between the first and second rigid support members.

摘要： A tabletop formed from slats for use in rigid, light-weight tables, such as portable banquet tables. The tabletop includes a center section formed from a plurality of open-channel, rectangular tubular slats that are laterally coupled together. Each slat has a top wall that aligns with top walls to form the upper working surface of the tabletop. Each slat also has downwardly-projecting sidewalls and a bottom wall with a longitudinal slot running the length of the slat to form the rectangular, downwardly-orientated channel. The adjacent contacting sidewalls of adjacent slats coupled together to form substantially vertical support beams. The tabletop further includes a pair of elongate end caps disposed on opposite ends and spanning the plurality of slats of the center section, with each end cap having a plurality of finger pairs extending into the plurality of slats with a center slot the receives a support beam therein.

摘要： A folding chair has a support frame with a back support portion, front leg portions, and rear legs. A seat is pivotally coupled to the support frame. A flexible back support is coupled to the support frame, and has a lumbar support member extending down from the back support to reach a lumbar region of a user's back. The lumbar support member extends from the back support into a space between the back support and seat. The seat pivots in a downward direction away from the back support and lumbar support ID member, so that the seat folds without interfering with the lumbar support member. The back support also has a perimeter flange disposed across the rigid back support perimeter, and free to move with respect to the rigid support frame in response to a load applied to the flexible back support. The perimeter flange extends across a gap created between the flexible back support and the support frame, such that when a load is applied to the back support and the back support flexes, causing the gap to open, the perimeter flange conceals the gap as the flexible back support goes from a loaded position to an unloaded position, thereby preventing pinching of articles of clothing or skin of a user.

摘要： A portable elevated platform includes a plurality of decks positionable adjacent one another in a flat configuration. Each deck includes an upper flat surface, and a plurality of contiguous sides extending around a perimeter of each deck. Each side includes an insert extending outward from the side and adjacent a corner of the side, and a receptacle extending inward into the side and adjacent an opposite corner from the insert. Each side of each deck is positioned adjacent any side of any other of the plurality of decks with at least one contiguous corner of each deck aligned such that the inserts and receptacles of the adjacently positioned sides mate together.
