A deployment mechanism for a bariatric ramp which has a drive motor pivotally secured to one side of the ramp platform. The deployment mechanism includes a lever located in a housing on the opposing side of the platform ramp. One end of the lever being connected to a platform pivot bar and the other end being connected to a traction gas spring secured within the housing. The spring mechanism comprises a drive shaft having a first and second torque levers located either end of the drive shaft. The drive shaft being rotatable as the platform is deployed such that the torque levers move between a first position whereby only the first torque lever acts on the spring and to a second position whereby neither first nor second torque levers act on the spring and to a third position whereby only the second torque lever acts on the spring.

A moveable ramp and method of moving cargo using a moveable ramp. The moveable ramp includes a ramp structure comprising a plurality of planar portions including a lower inclined portion, an upper inclined portion, a first horizontal portion extending between the lower inclined portion and the upper inclined portion and a second horizontal portion extending from an upper end of the upper inclined portion wherein the horizontal portions act as landing zones for a delivery tug moving the cargo onto and off of the ramp. The ramp also includes a locking mechanism at the top end to secure the ramp to a pallet, for sample. The ramp may further include automatic struts such as gas struts.

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.

A wheelchair ramp system includes a ramp having a floor having a plurality of layers. At least one guardrail is secured to the side of the ramp for providing a safety barrier to persons using the ramp system. The plurality of layers include a base, a foil isolator; a heating element, a heating element cover and a flooring cover. The ramp system is divided into a plurality of electrical zones such that not all zones are powered at the same time.

An automatic slope adjusting device is provided herein. The automatic slope adjusting device may include a slope type footrest unit configured to form a sloped passage; and a driving unit configured to adjust an inclination angle of the slope type footrest unit, and a length of the slot type footrest unit in a forward-backward direction thereof.

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 composite climb structure includes a climber, a horizontal planar structure, and a ramp coupled on to a base plate. The horizontal planar structure and the ramp are collinearly situated on opposite sides of the climber. The climber is pressed by a robotic vehicle moving on to it from the horizontal planar structure, the climber being pressed to a final position, wherein the angle of elevation (BOC) of the climber is same as the angle of elevation of the ramp, thereby facilitating traversal of the robotic vehicle from the horizontal planar structure on to the ramp.

A support assembly suitable for use in a modular ramp and platform assembly is disclosed. Additionally, an interface between components of the platform assembly, including, for example, the interface between the ramp section and the deck or platform section is provided, and may include support flanges that operatively interact with one or more slots positioned on the platform section.

A combination of elements to construct a threshold ramp construction includes tile elements each having a horizontal upper surface and ramp elements each having an upper surface including a sloped surface part and a horizontal surface part. The horizontal surface part adjoins the higher side of the sloped surface part. The tile elements and the ramp elements are configured to be arranged in superimposed layers to form the ramp construction, in which the superimposed layers include a lower layer and an upper layer, the upper layer supporting on the lower layer. In the ramp construction, the tile and/or ramp elements of the upper layer are arranged in a staggered position with respect to the tile and/or ramp elements of the lower layer.

A portable slope comprising at least a plate member and a first reinforcing part, and configured in a manner such that the first reinforcing part extends in the longitudinal direction of the slope, a hollow part is formed between the plate member and the first reinforcing part, the shape of the cross-section perpendicular to the longitudinal direction of the first reinforcing part is quadrangular, and the like. Provided is a portable slope to be used to bridge a difference in step produced between buildings and train car bodies, the portable slope being lightweight and exhibiting excellent load bearing characteristics and durability, making it possible for a wheelchair-user to safely travel on the slope by the positioning of derailment prevention walls on both lateral surfaces of the slope, and further exhibiting excellent portability as a result of the slope itself being lightweight.
