  • Patent number: 5513508
    Abstract: An apparatus for inflating inflatable articles, such as bicycle tire inner tubes, and for securing mobile articles, such as bicycles, to other objects. In one preferred embodiment, a first length of cable and a second length of cable are kept within a housing until needed to secure the article to an object. A cable holding sleeve holds the lengths of cable in a substantially side-by-side relationship when the cables are within the housing. When needed, the lengths of cable are withdrawn from the housing, passed through the frame of the article, around the object and the two ends of the cables are locked together by way of, for example, a cylindrical combination lock. When the first and second lengths of cable are unlocked, a constant tension spring, provided in some embodiments, retracts the lengths of cable back into the housing. Other embodiments of the invention are provided with a pump piston at the end of the lengths of cable which remain within the housing.

    Abstract: A tight fitting, tubular cover designed to protect portable, (attached to bicycle), bicycle tire pumps. The cover itself is constructed of a stretchy material (10) to facilitate a tight fit around the tire pump. A zipper (20) is incorporated into the body (30) of the pump cover to ease insertion and removal of the pump into and out of the pump cover. When zipped shut, the pump cover forms a tight fitting barrier that protects the valve mechanism and other vital components of the bicycle pump from foreign matter.

A tube extends partially into the post and carries a diaphragm on its inner end. The diaphragm is engageable with the inner surface of the post and compresses air in advance of the diaphragm when the diaphragm moves toward the upper end of the post. A check valve near the diaphragm permits only a one-way flow of air, namely in the direction through the tube and away from the upper end of the post. A lower member on the outer end of the tube allows a flexible hose to be coupled to the tube so that compressed air from the tube can be directed into the valve stem of a device to be inflated.

  • Patent number: 4712592
    Abstract: Bicycle pump apparatus includes a cylinder portion, a piston portion, a handle portion, a seat mounting portion and an air discharge portion. The cylinder portion includes an elongated tubular section, the tubular section having an external diameter slidably engageable snugly with a seat post receiving section of a bicycle frame. The piston portion includes an elongated rod member having a length slightly longer than the tubular section. A transverse plunger member is affixed adjacent one end of the rod member, the plunger member having a diameter substantially equal to the internal diameter of the tubular section to provide a snug fit therebetween A transverse guide section is disposed adjacent an opposite end of the tubular section aligning and maintaining the rod member along the centerline thereof.

  • Patent number: 4352503
    Abstract: An automatic transmission for a human powered vehicle is disclosed having an improved speed sensing mechanism. A rotatable shaft is journalled in a support frame mounted on the vehicle and has a plurality of outwardly extending arms fixed to the shaft. Weights are slideably attached to each of the arms to slide along the arms and engage a thrust member. The thrust member has a surface at an acute angle with the axis of the shaft and is axially slideable along the shaft. A spring urges the thrust member toward the weights and a linkage connects the thrust member to the shift member of the transmission. The weight members are forced outwardly by centrifugal force a distance which is a function of a bicycle speed. The weight members force translation of the thrust member along the axis of the shaft a distance proportional to bicycle speed causing a proportional movement of the shift member.

  • Patent number: 4226435
    Abstract: An oscillating pedal bicycle in which the downward force exerted by a rider is converted from the oscillating motion of the pedals into a unidirectional rotation of the drive wheel. The oscillating motion of the pedals is transmitted by flexible tension members to a conversion mechanism for converting the linear motion of such tension members into the rotary motion of the drive wheel. Maximum utilization of the motive power of the rider is achieved through the use of a quick-release, variable position body restraint and a variable height seat, both of which are adjustable while the bicycle is in motion, while maximum transfer and conversion of such motive power is achieved by an improved pedal return and tension member rewind mechanism and an improved drive mechanism. Pedal stabilizers, rotatable foot restraints and foot actuated lever control mechanisms are provided to maximize motive power and efficiency.
