The present embodiments provide an aviary, a walkway for an aviary, and a walkway system for an aviary. The walkway includes a ramp and at least one support disposed below the ramp.

A ramp kerb, for supporting a transverse edge of a ramp surface and a ramp lip extension having an attachment portion, comprises a first longitudinally extending channel open at an inner transverse edge of the ramp kerb for receiving a transverse edge of the ramp surface and a second longitudinally extending channel open at the inner transverse edge of the ramp kerb for receiving an attachment portion of the ramp lip extension. The first and second longitudinally extending channels are vertically spaced.

A device for displaying images for stands or stairways in a public venue includes a controller and a set of electronic screens connected to one another. Mounting devices secure the electronic screens to the risers of an existing stairway or stand. The controller controls displaying an advertising motif distributed between all the electronic screens.

An amusement park attraction system includes a user path extending through at least a portion of the amusement park attraction system, a railing extending along the user path, and a platform slidingly and rotatably coupled to the railing. The platform is configured to translate along the railing to position the platform relative to the user path, and the platform is configured to rotate relative to the user path to adjust between a stowed configuration and a deployed configuration.

A modular system including a surface-defining assembly having a plurality of panels. Each panel includes a plate portion, a first connector disposed towards and extending along a first side of the plate portion, and a second connector disposed towards and extending along a second side of the plate portion. The first and second connectors of adjacent panels are configured to engage one another to thereby engage the plurality of panels with one another in side-by-side relation such that the plate portions cooperate to define a continuous surface of the surface-defining assembly.

A ramp for assisting the loading of a vehicle onto a rollback car carrier or the like. The ramp including a front ramp assembly, a middle ramp assembly rotatably connected to the front ramp assembly, a rear ramp assembly rotatably connected to the middle ramp assembly, and a trailer abutment section positioned adjacent to the rear ramp assembly.

A lightweight universal panel mat made of plastic or elastomeric material and having a first section that provides a relatively flat, textured or structured top surface to facilitate movement over the mat and a second section having geometry that includes a plurality of cells having top surfaces that support the first section. The panel mats have first, second, third and fourth sides that are configured to matingly engage or connect to the second, third, fourth and first sides, respectively. The connection can be by insertion or snap-locking of one side to another, or by the use of fastening elements that more securely holds the sides together. Thus, similarly configured panel mats can be connected by interlocking to form a temporary support surface, deck, walkway or roadway. Additional side ramps and adapters can be used to facilitate installation of the mats and access to the upper surfaces of the joined mats.

In a mechanism for recycling energy from stairs (200), a step platform (210) is moveable between an upper and lower position. An energy storage device (220), coupled to the platform (210), stores energy when a downward force is applied thereto, causing the step platform (210) to move to the lower position. The energy storage device (220) also releases stored energy as the step platform (210) moves from to the upper position. A controllable locking mechanism (240) locks the step platform (210) in the lower position when the downward force has caused the step platform (210) to move into the lower position. A sensor (250) determines when a downward force has been applied to the next higher step platform (250). A controller (300) signals the controllable locking mechanism (242) to unlock the step platform (250) when the step platform (250) is in the lower position and when the downward force has been applied to the next higher step platform (250).

A method or system for constructing a non-slip ramp having at least two sloped ramp stringers and a starter wedge having a sloped side and an open side. A non-slip deck board is slid into the open side of the starter wedge and at least two tread plates, each providing spacing between two adjacent non-slip deck boards, each tread plate having a flat top section with a substantially L-shaped section attached perpendicular to the flat top section, with the bottom of the L fitting below one of the adjacent deck boards. The at least two tread plates are attached to the at least two sloped ramp stringers and an end-cap attached to a last non-slip deck board.

A wheelchair ramp system includes a ramp constructed from at least one structural insulated panel (SIP) having a foam core sandwiched between two structural facing panels such as oriented strand board (OSB). An outdoor exterior coating such as polyaspartic coating covers the SIP panel for allowing the SIP panel to be resistant to outdoor elements. At least one guardrail or handrail is secured to the side of the SIP for providing a safety barrier to persons using the ramp system.
