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 block-type modular ramp is to be provided in a place where a step or bump is formed. The block-type modular ramp includes block bodies arranged in a horizontal direction and stacked vertically to form a backbone, a fastening member for fastening the block bodies arranged in the horizontal direction to each other, a fixing pin for fixing the block bodies stacked vertically to each other, a fixing member coupled to the block bodies and fixing the block bodies to a floor surface where to install the ramp, fastening grooves formed in the block bodies, and fixing holes formed in the block bodies in an up-down direction.

A ramp system 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 snap lock system for connecting adjoining countertops comprises: a first locking unit comprising a first surface and an opposite second surface, the second surface being attachable to a first countertop, wherein the second surface has a profile comprising a projection, a first recess, and a second recess; a second locking unit comprising a first surface and an opposite second surface, the second surface being attachable to a second countertop, wherein the first surface has a profile comprising a projection and a recess; the second surface comprises a recess; and a third locking unit comprising a resilient member and a chamfered longitudinal edge, accommodated in a locking groove defined by the second recess of the first locking unit and the recess of the second locking unit. The profile of the second surface of the first locking unit is configured to receive the profile of the first surface of the second locking unit to provide a connection preventing mutual horizontal movement between the first and second locking units. During connection of the first locking unit and the second locking unit, the third locking unit is configured to allow vertical mating of the first locking unit and the second locking unit and, after connection, the third locking unit is configured to prevent mutual vertical movement between the first locking unit and the second locking unit.

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.

In a general aspect, a mat is disclosed for forming a transition between two surfaces of different elevation. The mat includes a carpeted layer secured to a foam layer. The foam layer includes first, second, third and fourth sides that define a perimeter of the foam layer. The foam layer also includes first and second channels extending in-plane through the foam layer from the first side to the second side. The first and second channels are configured to allow the mat to fold around a first folding axis into a folded position. The foam layer additionally includes relief cuts extending in-plane through the foam layer from the third side to the fourth side. The relief cuts are configured to allow the mat to fold around a second folding axis into a rolled position. A fifth side of the foam layer is mated to the carpeted layer, and a sixth side of the foam layer defines an interior boundary of the mat when the mat is in the folded position.

A ramp transportation system for a wheelchair enables transportation, deployment, and retrieval of a portable ramp by a single wheelchair occupant in the absence of external aid. The device comprises: a platform, configured to support the width of a wheelchair for crossing the platform, having a sufficient stiffness to support a wheelchair and occupant load; a lifting mechanism interface in the platform, disposed at least near each end of the ramp, configured to support cantilever lifting forces on the ramp; a lifting element, configured to engage the lifting mechanism interface and to apply a force to raise and lower the platform between a raised, stowed position and a lowered position, suitable for traversal; and a motor, configured to supply sufficient force on the lifting element to raise and lower the platform.

A deck apparatus for assembly with a pair of opposing brace frames interconnected by a pair opposing connector bases and a deck board top frame having a plurality of deck boards disposed thereon, the connector bases having opposing posts for being received in openings in a lower end of the opposing brace frames ends and the deck board top frame having posts for being received in an upper end of the opposing brace frames, and optionally attaching a stairs riser having a plurality of spaced-apart treads or a ramp riser for extending from a deck surface at a height to a vertically lower support surface.
