A system for sensing the angular position of a caster wheel includes a sensor mounted on a bearing which supports a shaft aligned with the rotational axis of the caster. A target on the shaft is detected by the sensor which generates signals indicative of the presence or absence of the target. The position of the target is coordinated with the position of the caster wheel such that the signals are indicative of the angular position of the caster wheel. The target may be a groove extending partially around the shaft and a remaining ungrooved portion of the shaft.

A caster wheel assembly for an outdoor power equipment machine includes a wheel mount and provides a double bell-shaped caster wheel including two bell-shaped halves, each bell-shaped half includes a central hub, a smooth transition portion, an outer circumferential rim, and a planar face. A ground contacting tread can be provided by the outer circumferential rims. A ground contacting tread can be provided by a resilient tread ring positioned between the two bell-shaped halves.

An actuating mechanism for a caster that brakes and positions the caster by means of a cam mechanism that enables braking of the caster using minimum forces developed on the brake lever or brake rod. The mechanism helps to handle casters of patient support apparatuses in hospital and nursery facilities easily, using minimum force developed by caregivers or by an electronic caster brake systems if used for braking of casters of patient support apparatuses, as well. The mechanism may produce an outstanding decrease of noise level of castors on patient support apparatuses.

An auxiliary drive device for a wheelchair has at least one freely pivotable electrically driven drive wheel and a coupling mechanism for coupling the auxiliary drive device to the wheelchair. The coupling mechanism includes a movable locking element which is movably supported in the coupling mechanism. The movable locking element can be in a locking position in which it causes locking in a positive-locking manner so that the auxiliary drive device is coupled to the wheelchair and, by operation of a handle, the locking element can be moved in a release position in which uncoupling of the auxiliary drive device from the wheelchair is possible.

The present disclosure generally relates to an omni-direction wheel system and methods for controlling the omni-direction wheel system. The omni-direction wheel system includes a plurality of suspension systems that operate independently of one another. Each suspension system may include an electromagnetic steering hub configured to rotate a wheel 360 degrees about a vertical axis based on a polarity of an electromagnetic signal applied to the electromagnetic steering hub. The suspension system may further include an in-wheel motor configured to rotate with the wheel and drive the wheel about a horizontal axis.

The present invention relates to a castor wheel structure, comprising a wheel part (18) and a castor wheel house (28), on which a transition element can be mounted, such as a spindle structure (1) or a flange structure (2), which again can be mounted on equipment that is to be made mobile, which wheel part (18) is unilaterally suspended and arranged about a substantially horizontal shaft on the castor wheel house (28).

An enclosure including an upper frame, a lower frame, and a lift mechanism operably coupling the upper frame and the lower frame together. The lift mechanism includes first drive shafts and a second drive shaft operably coupling the first drive shafts for operation in unison, and an input operably coupled to at least one of the first drive shafts or the second drive shaft. The lift mechanism transitions the enclosure between a stowed state and a deployed state during a movement of the actuator.

A wall configured to couple to a shelter and extend around at least a portion of a perimeter of the shelter. The wall includes a first end having a first attachment mechanism configured to engage with a second attachment mechanism of the shelter, a second end opposite the first end, a sidewall extending between the first end and the second end, and a third attachment mechanism coupled proximal to the second end and configured to engage with a fourth attachment mechanism disposed on the shelter to couple the wall to the shelter.
