An adjustable stair ramp includes a pair of risers, a series of treads, and an adjustable support leg. Cross members extend between the two risers. Each cross member has a pivotal brace with a top edge. The adjustable support leg has a main leg portion pivotally coupled to the risers. The main leg portion has an upper portion and a lower portion pivotally coupled to the upper portion. Each tread has bottom surface with a first receiving groove and a second receiving groove configured to receive the top edge of the respective brace. Each tread is pivotally coupled to the risers for pivotal movement between a high step position, a low step position, and a ramp position. The stair ramp is reconfigurable for use as a high stair, a low stair, a high ramp, and a low ramp through the positioning of the support leg and the treads.

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.

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 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.

A modular system includes a post and first and second rail segments. Each of the first and second rail segments includes a tube defining a substantially hollow interior with an internal surface and an external surface and a web connected to the internal surfaces of the tube and extending across the hollow interior thereof. The web includes at least one screw boss configured for receipt of a fastener to enable engagement of the rail segment with the post.

A pet staircase may be formed by joining modular units to each other in succession and that overlie a household staircase. They are retained in position over the household staircase. Each modular unit has stairs and/or ramps. The treads may be adjusted so that they all are parallel to each other and extend horizontally.

A heated wheelchair ramp system includes a ramp constructed from at least one structural insulated panel (SIP) having a foam core sandwiched between two oriented strand board (OSB) panels. A polyaspartic coating covers the SIP panel for allowing the SIP panel to be resistant to outdoor elements. One or more heating elements are configured within channels in the SIP to provide heated to the SIP. A metallic sheet is configured adjacent to the heating element(s) to provide heat distribution to the OSB panel(s). Finally, 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.

A ramp system includes a rail with an outer wall that defines an extent of the ramp in a width dimension. The rail includes an inner wall that is connected to the outer wall at a curb head. The inner wall extends away from the curb head at an angle relative to the outer wall. A side wall is oriented parallel to the outer wall. A lower end of the side wall is connected to a lower end of the outer wall by a bottom wall. A shelf is connected between an upper end of the side wall and a lower end of the inner wall. The shelf extension is connected between the lower end of the inner wall and the outer wall. A deck is secured to the shelf.
