The first locking mechanism is placed in a locked position and the second locking mechanism is placed in an unlocked position to allow the first and second sectional ramps to be coupled together and moved from the stored position to the deployed position through the first door. The second locking mechanism is placed in a locked position and the first locking mechanism is placed in an unlocked position to allow the first and second sectional ramps to be coupled together and moved from the stored position to the deployed position through the second door.

A submergible activity platform for attachment to an associated structure on a body of water is disclosed. The activity platform for supporting persons engaged in water activities includes a platform area extending outwardly from and alongside the associated structure. A support structure is carried by the activity platform for mounting the activity platform to the associated structure so that the activity platform is located at a desired depth in the water when mounted to the associated structure. A walkway is included in for providing access between the associated structure and the activity platform when submerged. The activity platform includes a water activity section free of the walkway where water activities may take place. The activity platform also includes a plurality of water flow passages for allowing water to flow through the activity platform when submerged to reduce the force of water currents against the activity platform.

A foldable bridge platform including a platform, a base bracket with casters installed beneath the bottom thereof, and a vertical rail erected and secured on the base bracket which provides the platform with a guide for adjusting the height thereof. The platform includes at least one main board and two side boards which are pivotally connected to the outer sides of the main board. The main board has a plurality of supporting bulges fixed at the outer sides thereof in order to support the horizontally unfolded side boards. By folding up the side boards of the platform, the width of the bridge platform can be greatly reduced. The foldable bridge platform is thereby convenient for movement and storage.

Various embodiments of the present invention are directed to a ramp having certain structural properties and having polymer-based decking elements. In one embodiment of the present invention, at least one surface of the polymer-based structural member includes a number of traction ridges. The traction ridges provide a gripping surface to promote ease of motion when moving across a floor or walkway constructed from one or more polymer-based structural members.

A modular fire prevention flooring system includes a plurality of fire prevention flooring planks. Each plank is generally tubular and forms a drain channel. Fluids spilled onto the upper surface of the flooring system may drain through a plurality of drain holes formed in the upper surface of the planks. The planks may further include a metal filler positioned within the drain channels to stop combustion of burning fluids spilled into the drain channels. The metal filler may break up burning liquids and remove heat therefrom. In some embodiments, a purging fluid may be flowed through the planks to purge any spilled fluids therefrom.

An apparatus for facilitating animal or vehicle movement between different surface elevations includes multiple floor panel members, including a first floor panel member and a last floor panel member. Each of the floor panel members are slidably attached to an adjacent one of the floor panel members. The floor panel members, when extended, form a ramp having a length which is variable, the floor panel members being adapted to nest within one another when retracted. The apparatus further includes a housing configured to enclose the floor panel members when retracted. The last floor panel member is coupled to the housing in a manner which enables the ramp to be slidably removed from the housing without having the ramp disengage from the housing. The housing includes a front panel removably attached to the housing for securing the floor panel members within the housing when the ramp is retracted.

A recreational vehicle (RV) includes a ramp door configurable as a ramp or as a patio deck. A stair is attachable to a side of the door. A railing extends about the perimeter of the door when in the deck configuration. First and second support cables may be connected between the door and the RV to support the door when in the deck configuration.

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 upper surface and a second section having geometry that includes a plurality of cells having top surfaces that support the first section. The mats also include first, second, third and fourth sides forming a perimeter of the mat, wherein the first and second sides include upper structures having a sloped lower surface and the third and fourth sides include lower structures having sloped upper surfaces. The sloped surfaces are configured to allow for overlapping with sloped surfaces other like mats for interlocking therewith while forming a generally flat continuous top and bottom surface of the overlapped mats. The mats may be interlocked by a fastening member which fits in aligned openings of the adjacent mats for connection therewith.

A ramp system has a plurality of modular components adapted to be interconnected in a desired configuration. The modular components include an entry ramp module (10, 80), an exit ramp module (80) and a landing module (100, 180) therebetween. Each modular component has a floor assembly (12), handrail assemblies (14, 16) and leg assemblies (18). Each of the handrail assemblies have posts (22, 24) which are adapted to support a handrail (26). The posts are collapsible by folding inwardly towards a deck (28) of the floor assembly through operation of a folding means (30) interconnecting the floor assembly and each post of the handrail assembly. The posts of the handrail assemblies are reversibly collapsible from an erect position, where the ramp system can be used and the handrail assemblies can support users of the ramp system, to a compact position, where the ramp system can be stored, packaged and transported until required for assembly on site.
