| The stair-climbing apparatus has a series of articulating wheel sets extending below the platform. All of the wheel sets are vertically adjustable to negotiate stairways and similar changes of elevation. The lead wheel set is fixed longitudinally relative to the platform, while following wheel sets are longitudinally adjustable to adjust for the pitch or slope of different stairways. The apparatus uses sensors (e.g., mechanical, infrared, ultrasonic, etc.) to detect the presence of the stair risers and their height, control of the assembly being accomplished by a control circuit on board the machine. The wheel sets are raised and lowered independently of one another by pantograph mechanisms extending between the platform and the wheel sets. The horizontally adjustable wheel sets are positioned by a longitudinally disposed rack on the platform. | ||||||

| An attachment for a wheelchair includes a secondary front-wheel pair that is movable from a disengaged up position, to a deployed down position, and back again. In the disengaged up position, the secondary front wheels are up off the ground, so the primary front wheels of the wheelchair are in contact with the ground and thereby being used. In the deployed down position, the secondary front wheels are down in contact with the ground and are thereby being used, so the primary front wheels are now removed from contact with the ground and are no longer in use. In typical embodiments, the secondary front wheels are relatively larger wheels for traversing rough terrain, the primary front wheels are relatively smaller wheels for traversing smooth terrain, and the secondary front wheels move between the disengaged up position and the deployed down position in a pivoting motion. | ||||||

| An anti-tip system is provided for improving the stability of a powered vehicle, such as a powered wheelchair. The vehicle includes a drive-train assembly pivotally mounted to a main structural frame. A suspension system biases the drive-train assembly and its connected anti-tip wheel to a predetermined resting position. The drive-train assembly bi-directionally rotates about a pivot in response to torque applied to or acceleration forces on the vehicle. A linkage arrangement is provided and is characterized by a suspension arm pivotally mounting to the main structural frame about a pivot at one end thereof and an anti-tip wheel at the other end. The linkage may further include at least one link operable to transfer the bi-directional displacement of the drive-train assembly to the suspension arm. The link may include a bell crank member and/or may be resiliently compressible. | ||||||

| The present invention relates to a wheel suspension for mounting on a frame (3) of a vehicle, which, in its direction of propulsion, is arranged to be able to scale an obstacle (7), the wheel suspension (1) comprises a link element (9) arranged rotatably about a rotation point (R), to which rotation point (R), via the frame (3), can be applied a force (Gx) for propulsion, the link element (9) comprises a first and a second wheel axle (11, 13), the second wheel axle (13) serves as a moment axis (X) about which the link element (9) tends to rotate when a force (F) is applied to the first wheel axle (11) in the direction opposite to the direction of travel. The link element (9) acts as a lever arm by virtue of the rotation point (R) being situated at a distance from an imaginary straight line (L) intersecting the first and the second wheel axle (11, 13) and in a plane transversely to the extent of the moment axis (X). | ||||||

The link arm mount of the suspension mount has an upper pivot and a lower pivot. An axle tube is configured to rotatably support a pair of rear wheels, and an axle tube clamp engages an end of the axle tube. The axle tube clamp has a pivot and a lower shackle. The axle tube includes a link arm tube mount having a pivot. An upper link arm is supported for pivoting movement between the link arm mount upper pivot and the link arm tube mount pivot. A lower link arm is supported for pivoting movement between the link arm mount lower pivot and the axle tube clamp pivot. A resilient member is pivotally connected between the upper and lower shackles. | ||||||

| A patient support has caster devices supporting a frame for movement in relation to a supporting surface. A lift supports an auxiliary wheel in relation to the frame. A shaft may be rotatable to drive the lift to move the auxiliary wheel between a deployed position and a retracted position. The shaft may rotate to control deployment and retraction of the auxiliary wheel. A sensor may control deployment and retraction of the auxiliary wheel. An element may provide a dampening effect when the auxiliary wheel encounters a raised surface and urge the auxiliary wheel into contact with the supporting surface when the auxiliary wheel encounters a lowered surface. | ||||||
