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 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 ramp and/or platform assembly includes a decking system having a tread surface on at least a portion of a top deck surface of the decking system, wherein the tread surface includes a plurality of multi-tiered ridges on the top deck surface for contact with a traveling body on the top deck surface.

A ramp assembly includes a decking system and a handrail system, an interface between the decking system and the handrail system, and a support system pivotably coupled to the interface. Other embodiments include a swivel bracket and a method of assembling a ramp assembly.

In one embodiment of the present disclosure, a ramp and platform interface, includes a platform side defining one or more slots, the upper end of the one or more slots defined by a downwardly and inwardly extending lip; at least one support flange including a body, a lip disposed at the top edge of the body, and a flange section outwardly extending from the body, wherein the at least one support flange is selectively mounted to the platform side via the one or more slots; and a ramp section defining a support surface on a top side thereof and one or more support flange engagement structure on the bottom side thereof, wherein the ramp section is disposed in a supporting relationship with the platform side via cooperation of the flange section and the support flange engagement structure.

A ramp system is disclosed which may include first and second components. The first component may include horizontal and vertical portions, and a hook. The horizontal portion may be supported by a lip of a structure, and may have a width equivalent to a length of the lip. The vertical portion may be coupled with, and hang downward from, the horizontal portion, and may have the same width as the horizontal portion. The hook may be coupled with the vertical portion, and may have the same width as the horizontal portion. The second component may include a protrusion and channel. The protrusion may have a width equal or less than the width of the horizontal portion, and be supported by the hook. The channel may be coupled with the protrusion, and have the same width. The channel may receive a planar component which forms a sloped surface of a ramp.

A platform interface includes a platform, a hanger, and a ramping section. The platform defines a slot. The hanger has a body with a first end and a second end, a flange outwardly extending from the body and having a flange lip, and a gap extending between the first end and the flange lip. The ramping section has a hook configured to engage the flange such that the platform supports the ramping section via the flange. The gap is sized to prevent rotation of the hanger relative to the platform when the first end of the hanger is engaged with the slot and the hook engages the flange.

The disclosure includes a device and steps of a method for covering stairs from a first tread run to a last riser with a convertible ramp stair cover of a total variable length. The method includes extending a top end segment from a top joint of the convertible ramp stair cover a variable length to abut a top run of the staircase. The method additionally includes extending a bottom end segment from a bottom joint of the convertible ramp stair cover a variable length to abut the floor adjacent the staircase and changing an angle of the top segment with respect to the convertible ramp stair cover to match a surface of the top run of the staircase. The method yet includes changing an angle of the bottom segment with respect to the convertible ramp stair cover to approach a surface of the floor adjacent the staircase.

A device for helping a wheeled vehicle pass over an obstacle. The device includes a stationary frame with a bottom and two symmetrical parallel side walls; a plate provided with two ends, a first end being movable between a high position and a low position, and an assembly for driving the first end between a low position and a high position. The drive assembly includes: a linear ram mounted under the plate with a stationary end adjacent to the second end and rigidly connected to the bottom, a mobile end, and a carriage movable in horizontal translation and resting on guides mounted on the bottom of the frame. The carriage includes two tappets and a pair of arms, the arms being symmetrical, each arm resting on one of the tappets of the carriage, and each arm supporting the first end of the plate.

A ramp and/or platform assembly includes a decking system having a tread surface on at least a portion of a top deck surface of the decking system, wherein the tread surface includes a plurality of multi-tiered ridges on the top deck surface for contact with a traveling body on the top deck surface.
