  • Patent number: 7364179
    Abstract: A suspension system that requires minimal or no welding and can be easily adapted for use with a variety of frame configurations without adversely affecting the frame integrity. One embodiment includes a top bearing (21), a base bearing (31), an upper clamp (19), and a strut (41). The bearing inserts may be secured with conventional fastening means, for example, adhesives or screws. In one embodiment, a lower spring seat may be secured with a snap ring and heat sensitive materials may be used. Thus, the suspension systems may, if welding is necessary, be installed using standard frame welding practice without the need for extraordinary or special fixtures or procedures. Options are thus now available in component material selection and suspension configuration which have previously been limited because of the heat of welding. This frame integral technology may be used with only minor changes to current fabrication practices.

  • Patent number: 7116553
    Abstract: The invention provides an expandable modular enclosure system for enclosing circuit boards connected by a stackable bus. The enclosure system includes one or more carriers and spacers, a base unit, and a top unit. The spacers and carriers are alternately stacked between the base unit and top unit, and each circuit board is mounted to a carrier. A side portion with recessed vents extends from one side of each carrier, and each carrier and spacer define an opening. Air flows through the vents, over each circuit board, and through the openings in the carrier to cool the circuit boards. Circuit boards with varying functionality can be included in the enclosure, and as many circuit boards as are necessary can be enclosed without increasing the size of the footprint of the enclosure.

  • Patent number: 6945135
    Abstract: A bicycle stem may include a body portion and a handlebar clamping portion connected thereto, and a handlebar clamping member cooperating with the handlebar clamping portion to clamp the bicycle handlebar. The handlebar clamping member and the handlebar clamping portion may each have a cavity in a respective medial portion thereof to accommodate an enlarged diameter portion of the handlebar. The handlebar clamping member may have a generally rectangular shape with a recess therein defining with the cavity a pair of spaced apart contact areas for contacting the handlebar. The handlebar clamping member may also be completely removable from the handlebar clamping portion in some embodiments, to facilitate installation of the handlebar. The handlebar clamping portion may also have a recess therein defining with the cavity a pair of spaced apart contact areas for contacting the handlebar.

  • Patent number: 6708582
    Abstract: A bicycle gear shifting system includes a gear shifting derailleur, a rotatable shift member to be rotatably carried by handlebars of the bicycle and connected to the gear shifting derailleur, and a hand attachment to be carried by a hand of a rider. The rotatable shift member and the hand attachment may each have respective mating surfaces for positively engaging one another to facilitate gear shifting by the rider and are readily releasable to permit the rider to change hand positions. More particularly, the mating surfaces may include pairs of corresponding recesses and projections. The pairs of corresponding recesses and projections may also be tapered. Furthermore, the mating surfaces may engage in superposed relation upon radial squeezing of the hand of the rider. According to another embodiment, the mating surfaces may engage in side-by-side relation upon lateral positioning of the hand of the rider.

  • Patent number: 5553880
    Abstract: An energy-absorbing apparatus for a bicycle frame maintains critical spatial relationships by allowing the seat and the pedal assembly to move slightly, together as a unit, relative to the bicycle frame proper. A telescoping portion of the apparatus has an inner tube housed inside an outer tube. The inner tube has a seat post connected to its top end and a pedal crank axle housing connected to the bottom end. The outer tube is in a fixed, integral relationship with the other frame members. Any of a number of combinations and variations of adjustable spring/damper means isolate the inner tube from the outer tube. Numerous features, including dust boots and a rider-activated keyway lock, can be incorporated into the frame design. The telescoping design reduces impact forces without causing undesirable changes in frame geometry or undesirable changes in the distance between the seat and pedals.
