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.

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： A removable stairway device configured for attachment to a platform includes a removable step attachable to the platform and extendable from the platform in cantilever fashion. A gap is formed between the step and the elevated deck of the platform when the removable step is attached to the platform. A lock plate is pivotally coupled to the step. The lock plate pivots to cover the gap between the step and the elevated deck. A flange extends from the lock plate and engages a side of the platform to lock the step to the platform when the step is attached to the platform and the lock plate is pivoted to cover the gap.

摘要： The opposite plastic walls 20a and 20b can be made from a polymeric resin material such as thermoplastic or thermoset resin, and/or can be made from olefins, styrenes, nylons, or mixtures of these polymeric families. In one aspect, the opposite plastic walls can be formed from an olefin, such as polyethylene or polypropylene, or the like. In another aspect, the opposite plastic walls can be formed from a styrene, such as acrylonitrile or butadiene styrene, or the like. In still another aspect, the opposite plastic walls can be formed from a mixture of olefins and styrenes. The polymeric resin material can also be made from recycled olefin, styrene, or nylon products. It will also be appreciated that the material of the walls can include additives, such as glass, fiber, talc, UV resistive or protective materials, etc. In one aspect, plastic granules of different colors can be combined to obtain a wall color that is a composite color to more readily simulate another material.

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 telescoping leg for supporting an elevated platform includes an outer leg. An inner leg is slidably disposed within the outer leg. An off-axis slot is disposed through a sidewall of one of either the inner leg or the outer leg and an aperture is disposed in the other. The inner leg is slidably positionable within the outer leg to align the off-axis slot with the aperture. A pin is disposable through the aperture and the slot when the aperture and the slot are aligned such that a bearing surface of the pin contacts a bearing surface of the slot to laterally push the inner leg against the outer leg.

摘要： A chair foot device for a wire frame chair stackable with other wire frame chairs includes a lower surface disposable on a support surface. An upper surface, opposite the lower surface is sized and shaped to carry the lower surface of an adjacent foot from an adjacently stacked upper chair. The chair foot also includes an alignment protrusion disposed on one of the lower and upper surfaces and an alignment indentation disposed on the other of the lower and upper surfaces. The alignment protrusion is sized and shaped to be receivable within an alignment indentation of a corresponding foot from an adjacently stacked chair. The foot is sized and shaped to carry an applied load from an adjacently stacked upper foot and to transfer the applied load to an adjacent load bearing surface. The foot is also sized and shaped to protect the wire frame chair from damage during stacking.

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.
