  • Patent number: 7036620
    Abstract: A variable speed transmission having a plurality of tilting balls and opposing input and output discs is illustrated and described that provides an infinite number of speed combinations over its transmission ratio range. The use of a planetary gear set allows minimum speeds to be in reverse and the unique geometry of the transmission allows all of the power paths to be coaxial, thereby reducing overall size and complexity of the transmission in comparison to transmissions achieving similar transmission ratio ranges.

  • Patent number: 7032916
    Abstract: A single-piece side wheel attachment member for removably attaching an auxiliary side wheel to a bicycle is provided. The attachment member has a single-piece molded structure, including an upper vertical portion and a lower substantially horizontal spindle portion connected through a C-shaped compliant structure for allowing the spindle portion to move vertically when subjected to force. In its natural unbiased condition, the vertical and horizontal portions of the member extend generally perpendicular to one another. The upper vertical portion includes a projection and at least one through-hole for insertion on the rear wheel axle of the bicycle. The horizontal spindle portion is rotatably engaged by the auxiliary side wheel, therefore acting as its axle. Both ends of the attachment member can angularly move relative to one another due to the C-shaped compliant structure.

  • Patent number: 7029019
    Abstract: The present invention is an attacher having a receiver extending rearward and a boom extending upward and rearward from a base. One or more connectors, such as a gooseneck hitch or a hook, can be at the distal end of the boom. The boom is supported by a pair of bent arms that interconnect the base and the boom. The bent arms connect to the boom near the distal end of the boom. The present invention can connect directly to a three point hitch of a host vehicle, or to an adapter plate having a three point hitch. To accomplish this, two pins extend out from opposed ends of the base and a U-shaped bracket is on the boom. At least one plate can be recessed within the base to anchor the pins to the base, in addition to welding the pins to the base.

  • Patent number: 7029021
    Abstract: The specification discloses several embodiments of an interlocking device. The specification discloses a preferred embodiment of an interlocking device having an inner bar slideable within the confines of an outer bar. The outer bar has a first end and a second end. When the inner bar slides towards the second end of the outer bar, a plug, which is attached to the inner bar, is adapted to abut a plug barrier thereby preventing the inner bar from sliding towards the second end. The outer bar of the interlocking device further defines an interlocking member passage and an interlocking member stop. The interlocking device further has an interlocking member attached to the inner bar. When the inner bar slides towards the first end of the outer bar, at least a portion of the interlocking member moves transverse to the sliding axis of the inner bar and into the interlocking member passage.
