Handicapped walker stair climbing aid - comprises half height steps extending over part of main steps width

Abstract: People with limited leg or hip joint movement are provided with assistance in climbing steps. The steps in a staircase (1) have intermediate steps (2) mounted on them, halving their height, but extending only over part of stair width. The underside of the auxiliary piece used for this pref. has a non-slip surface, and it may be collapsible . Cork is a suitable material. Different types can be fixed or portable, so that suitable provision can be made in buildings visited by sufferers, as well as in hospitals or their own homes.

Stair climbing and traveling full-automatic electric wheelchair

Abstract: The utility model relates to a stair climbing and traveling full-automatic electric wheelchair. The stair climbing and traveling full-automatic electric wheelchair comprises two power wheels and six non-power wheels, wherein four wheels are arranged at each side; the power wheels and the non-power wheels are connected by arc plates and chain wheels are connected with chains to form staggered wheels; the wheels are provided with the chain wheels; each two wheels are connected by one chain; the arc plates are hinged and hung with support frames to form a wheel upper traveling suspension device main body; telescopic installation gear pairs, seats and clutch regulation mechanisms are arranged on the support frames; racks are arranged on the seat; a storage battery box is arranged below the seat; electric controllers are arranged at the positions of seat hand rails; sector wheels are fixed on the support frames; and a timely gravity center regulation signal and seat back-and-forth sliding power are provided. The product is the stair climbing and traveling full-automatic electric wheelchair, is greatly convenient for old people, the disabled and patients to go out and climb stairs and has the characteristics of safety, stability, convenience and rapidness.

Stair-climbing robot and control method thereof

Abstract: Provided are a stair-climbing robot and a method for controlling the same. According to an embodiment of the present invention, provided is the stair-climbing robot as a robot climbing stairs, comprising: a frame; a front leg whose one end is combined to be rotated with the front of the frame; a rear leg whose one end is combined to be rotated with the rear of the frame; a wheel combined to be rotated with the other end of the rear leg; and a controlling part for controlling the driving of a driving part for separately rotating the front leg, the rear leg, and the wheel. According to an embodiment of the present invention, a robot having a small size can climb or descend stairs, and the robot can climb or descend stairs while maintaining the level.

The role of energetic resources on perception and physical activity choices

Abstract: Observations of human behaviour show a tendency for avoiding energy expenditure through stair climbing where possible. Similarities between demographic influences in stair avoidance and explicit perceptions of geographical slant outlined in the ‘economy of action’ account (Proffitt, 2006) suggest that this avoidance behaviour might be due to a perceptual bias. Chapter two of this thesis investigated measures of slant perception linked to action. It appears that these ‘haptic’ measures tap into a perceptual process that is more in touch with the physical reality of the environment than conscious awareness. Chapter four demonstrated that fundamentals of the economy of action account generalise to the perception of staircases, and to a newly developed laboratory setting. Depletion of energetic resources, manipulated through fatigue, resulted in steeper explicit estimates of staircase steepness. In reaction to published criticisms of the methodology used in this field, chapter five took a new approach to testing the effect of resources on perception. Two quasi-experimental field studies, designed to circumvent methodological issues challenging the validity of previous studies, demonstrated that available energy resources affects consciously perceived steepness in the built environment. Chapters six and seven built on this by testing the economy of action account as a model that explains stair avoidance behaviour. Encouragingly, across two different points-of-choice between stair climbing and avoidance, explicit measures of perceived geographical slant were linked to reported prior stair climbing behaviour at one site (chapter six) and objectively measured behaviour at another (chapter seven). Collectively, these findings suggest that available energetic resources dictate the exaggeration of perceived geographical slant experienced at an individual level, and that this in turn influences stair choice behaviour, biasing those with less resources towards stair avoidance and energy preservation.
