  • Patent number: 6672680
    Abstract: To retain a decorative tubular cover having a given inner diameter over the axle hub of a wheel, a strap having a plurality of radially extending arms thereon is tightened around the circumference of the axle hub. The ends of the arms define a circle having a diameter a little larger than the given inner diameter of the tubular cover. The tubular cover is pushed over the arms until the open end thereof rests against the web of the wheel where it is retained by the outwardly directed forces applied by the arms.

  • Patent number: 6443528
    Abstract: A cover for a vehicle wheel having a drop center is generally complementary in shape to the wheel and has a plurality of connectors spaced around the inside surface thereof. Each connector has a moveable hook and an adjusting bolt. Rotation of the adjusting bolt in one direction extends the hook until it engages the shoulder in the cylindrical portion of the wheel formed by the drop center to thereby retain the cover to the wheel. Rotation of the adjusting bolt in the opposite direction withdraws the hook out of engagement with the shoulder such that the cover can be removed from or reinstalled to the wheel.

  • Patent number: 5366279
    Abstract: A cover for an oil hub extending through a truck wheel has a tubular body with a transverse surface at one end thereof. The inner diameter of the tubular body is a little greater than the outer diameter of the cylindrical section of the oil hub around which the body is fitted. A compressible sleeve, typically made of a foam rubber or the like, has an inner diameter a little less than the outer diameter of the cylindrical section of the oil hub, and has an outer diameter which is larger than the inner diameter of the tubular body of the cover. The cover is retained over the compressable sleeve by the radial force of the sleeve and by a double sided tape which is applied to the outer surfaces of the compressible sleeve and across the distal end of the oil hub.

  • Patent number: 5188320
    Abstract: A resilient member having a central section is adapted to fit against the chest of the infant and two generally parallel downwardly extending side sections are adapted to fit snugly under the arms and against the sides of the infant. The central section has an extension which extends over the neck such that when the member is fitted over the chest of an infant, with the sides under the infant's armpits, the extension is in proximity to the chin of the infant. An inclined groove is provided along the upper surface of the extension for frictionally holding a nursing bottle in an inclined angle relative to the mouth of the infant.
