Abstract: A device for Controlling pressure is disclosed which comprises a pump (28) having opposed pistons (30) which reciprocate in cylinders (40) carried by a casing (38). The pistons (30) are at the outer ends of rings (50) which are themselves fitted to an eccentric (26). The eccentric (28) is integral with a clutch plate (24). A second clutch plate (22) is fixed to a non-rotating axle (18) which itself forms part of a hanging counterweight structure (20). A piston (84) pushes the eccentric and clutch plate (26, 24) against the clutch plate (22) thereby to prevent the eccentric (26) tire from rotating with the rings (50) upon a sensor detecting that a tire has a low pressure in it. Stopping the eccentric initiates the pumping action of the pistons (30).

Abstract: A connection stabilizing mechanism between a solid tire and a bicycle rim. The connection stabilizing mechanism includes multiple fastening members connecting a solid tire with a bicycle rim. Each of the fastening members has a plate-shaped base section engaged with the bicycle rim and an extension section inserted into the solid tire. A free end of the extension section is inserted into the solid tire. A ratio of an extension length of the extension sect ion to a tire height of the solid tire is between 1:1.5 and 1:2.6, thereby maintaining a relative position of the center of a main body of the solid tire relative to the rim. Thus, the solid tire is prevented from being detached from the rim due to excessive lateral movement of the central position of the main body of the solid tire.

Abstract: An improved track frame assembly wherein the idler wheels are arranged to prevent loss of track contact with the terrain. Seriatim primary idler wheels are aligned to longitudinal outer lateral track edges. Secondary idler wheels are mounted interiorly of the outer wheels and longitudinally staggered to prevent the track from lifting or “caterpillaring” in spaces intermediate the primary idler wheels. The numbers, diameters, widths and positions of the secondary idler wheels are selected to overlap the track contact points of the primary idler wheels. A resiliently biased and/or slippery presser member, roller or slide assembly can alternatively be mounted to prevent vertical track flexion.
