TL;DR: In this article, a carrier with a base, a number of wheels attached to the base, and a spring biasing device for engaging with the stairs and for biasing the base while the base is moved relative to stairs, in order to facilitate the base of the carrier upstairs or downstairs.
Abstract: A carrier includes a base, a number of wheels attached to the base, and a spring biasing device for engaging with the stairs and for biasing the base while the base is moved relative to stairs, in order to facilitate the base of the carrier upstairs or downstairs. One or more posts are secured to the base, and one or more barrels are slidably engaged on the posts for engaging with the stairs. The spring biasing device includes a number of springs engaged with the barrels for for applying biasing forces against the barrels when the barrels are engaged with the stairs.

TL;DR: Kinematic and dynamic parameters of the exoskeleton motion are presented and discussed and virtual simulation results demonstrate the technical feasibility of the proposed solution, in case of stair climbing motion assistance for people with lower limb muscle weakness.
Abstract: In this paper the researches developed by the authors in the direction of motion assistance and rehabilitation for people with motion weakness are presented. Using wearable goniometers, experiments concerning stair climbing gait parameters determination are conducted. A robotic exoskeleton device is proposed to assist people with muscle weakness in the case of stair climbing activity. A virtual model of the exoskeleton and of human mannequin is developed in SolidWorks design environment. Using ADAMS software, a dynamic simulation for the assembly of virtual mannequin and motion assistance exoskeleton, in case of stair climbing is performed. Kinematic and dynamic parameters of the exoskeleton motion are presented and discussed. Virtual simulation results demonstrate the technical feasibility of the proposed solution, in case of stair climbing motion assistance for people with lower limb muscle weakness.

TL;DR: In this paper, the authors presented a stepping type stair climbing machinery for fixing a wheelchair or carrying goods, where the base main body is provided with a power device as well as a first driving shaft and a second driving shaft which are parallel to each other.
Abstract: The utility model provides a stepping type stair climbing machinery and belongs to the technical field of a stair climbing transportation tool The stepping type stair climbing machinery comprises a base main body for fixing a wheelchair or carrying goods, wherein the base main body is provided with a power device as well as a first driving shaft and a second driving shaft which are parallel to each other; the power device is used for driving the first driving shaft and the second driving shaft to rotate synchronously; two ends of the first driving shaft and the second driving shaft extend outwards out of the base main body and are respectively and fixedly provided with a stepping stair climbing component, and the stepping stair climbing component rises at least one time of the unit step height along with the rotation process of the first driving shaft or the second driving shaft The stepping type stair climbing machinery disclosed by the utility model is simple in structure, low in cost, capable of walking on a flat bottom surface and running on straightly-arranged stairs or steps and capable of running automatically without manual operation after the power device is started; meanwhile, a parallelogram structure of the stepping stair climbing component rotates inside a U-shaped bracket along with the rotation of the driving shafts, so that the stepping type stair climbing machinery is stable and rapid in operation

TL;DR: In this paper, a stair climbing aid for wheelchair occupants to allow autonomous stair climbing, based on the design known from the patent document GB 683 983, is presented. But the design does not consider the use of stairs.
Abstract: The invention relates to a stair climbing aid for wheelchair occupants to allow autonomous stair climbing, based on the design known from the patent document GB 683 983. With small modifications the known design becomes an autonomous climber. The preferred embodiment is an attachment for commercially available active wheelchairs and includes, in addition to the driven caterpillar track (5), two levers (7) which effect the transfer onto and off the stairs. The levers are rotatably mounted on the frame with their axis of rotation (8) approximately parallel to the rear edge of the seat. In contrast to what is known from GB 683 983, these levers execute full turns during the stair-climbing process. By virtue of these and other features of the levers, as described in more detail in the patent document, the transfer onto and off the stairs is accomplished reliably and automatically with only one active component, and the operation does not require bodily force or the help of another person. In combination with the low centre of gravity this results in a compact stair climber weighing less than 10 kg. During the stair-climbing process the large wheels of the wheelchair are removed and secured elsewhere.
