  • Patent number: 5257800
    Abstract: An improved baggage barrow, of which the retaining handle is mounted on the upper ends of two lower segment rods; the retaining handle is slidably mounted with a movable fastening member; the fastening member has two ball-shaped retainers to mate with two corresponding round holes on the lower segment rods and the upper segment rods so as to fix the upper segment rods when pulled out in place; the baggage barrow can be reduced in size simply by lifting the fastening member to have the ball-shaped retainers disengaged from the round holes of the upper segment rods, and then the upper segment rods can automatically be retracted in the lower segment rods. The stub tube at the lower part of each of the lower segment rods has a bead, which provides a retaining and positioning function upon opening the carriage frame; the baggage barrow is simple in operation, and the barrow can stand steadily without falling down.

  • Patent number: 5236222
    Abstract: A skate pole device can be used alone or in pairs by a roller skater in order to advance or retard movement along a skate surface. The skate pole has an elongated shaft with a handle portion on one end and a foot portion on the other end. First and second pads are mounted in the foot portion. The first pad is constructed of a type adapted to frictionally grip the skate surface so that the skater may exert a thrusting motion with the skate pole, and this material may be a stiff, yet resilient, rubber-like substance such as a soft thermoplastic. The second pad is constructed of a different type of material, such as a hard thermoplastic, that is adapted to act as a brake pad against the skate surface so that the skater may apply a drag force. A pair of such skate poles may be used and, if desired, interconnecting elements are provided to releasably secure two such skate poles alongside one another.
