Abstract: A tracked mobility device includes: a) a pair of independent, self-supported track drives defining a planar ground contact area; b) a multi-directional wheel having a raised position above the plane of the ground contact area, and a lowered position below the plane of the ground contact area; and c) an actuator for moving the multi-directional wheel to either its raised or its lowered position. When the actuator lowers the multi-directional wheel, part of the planar ground contact area is raised from the ground without raising all of the planar ground contact area from the ground. Each track drive functions independently so that bumps along one track may be traversed without tilting the entire vehicle. Each track drive may be attached to the vehicle body with flexible mounts that allow each track drive to independently tilt upward or downward as the device moves on its tracks.

Abstract: An electric vehicle includes a double-sided swing arm that supports a motor shaft, an axle, and a wheel by supporting a motor on one side of the wheel and a reduction mechanism on the other side of the wheel. In this case, the swing arm is composed of, on the one side of the wheel, plural separable arm portions. The arm portions have respective separation points on an outside or outer periphery of the wheel. With the components arranged in this manner, weight balance of the electric vehicle is easily achieved, and the operational efficiency of mounting, removal, and replacement of the wheel and the motor is improved.

Abstract: A pivot joint for a bicycle frame is described, which includes an inner bearing sleeve concentrically disposed within an outer bearing sleeve. The inner bearing sleeve has an outer bearing surface in rotatably sliding contact with an inner bearing surface of the outer bearing sleeve, such that the inner and outer bearing sleeves are rotatable relative to each other about a central pivot axis to permit relative rotation of the components joined by the pivot joint. Each of the inner and outer bearing surfaces includes a substantially axially extending region and at least one angled bearing region that defines an angled raceway surface thereon. The angled raceway surfaces are disposed at an angle relative to the central pivot axis and meet in bearing engagement with each other to define a slip plane disposed at the same angle.

Abstract: An apparatus for connecting a kingpin of a gooseneck or fifth wheel trailer to a towing vehicle includes a fifth wheel hitch having a hitch platform with a hitch head slidably mounted on the rails of a base platform; an articulating mechanism to displace the hitch platform to and from a forward towing station and a rearward towing station; and a latch having a latch pin to automatically lock the hitch platform at the forward and rearward towing stations and also having a biased spider device to automatically prevent the latch pin from re-locking the hitch platform when the hitch platform is released from a towing station until after the hitch platform has been displaced away from that towing station.

Abstract: A configurable large-depth panel display uses a number of frame members and a number of corner brackets coupled to one another to create an flexible and easily customized display device. The frame members relatively uniform, having a substantially constant cross-sectional configuration which is easily coupled to the frame members. The corner brackets can be configured in a number of different ways to produce a display product with a desired configuration. More specifically, the corner brackets can be configured to attach to frame members in a manner which produce an overall framework having multiple shapes and orientations, depending upon the desired design of the overall display. Various panels, brackets and supports can be easily attached to the frame members using integral portions of the constant cross-sectional configuration. Further, more complex displays can be easily created by simply attaching different framework components to one another thus creating a single structure with multiple panel members.

Abstract: A drive unit for a vehicle is provided for use as a robot in pipe systems, cavities or the like. The drive unit includes at least one ring-like outer wheel and at least one driven magnetic wheel. The outer and the magnetic wheels have axes parallel to each other and are arranged eccentrically to one another, and engage one another such that when rotating relative to the outer wheel, the magnetic wheel delineates with its wheel axis a concentric circle lying within the outer wheel. In such a drive unit, stronger magnetic adhesion is enabled by the outer and magnetic wheels being arranged one behind the other in an axial direction. The engagement between the outer and magnetic wheels is effected by a circular, concentric disk connected securely against rotation to the magnetic wheel and rolls with its outer peripheral surface on the inner peripheral surface of the outer wheel.
