Definitions

  • This invention discloses an unitary skate truck. More particularly, an integral truck made especially for roller skate, skateboard, or the like enales riders to maintain a better stability and to have a better maneuverability.
  • Trucks of various types have been devised and adapted on roller skate, skateboard, or the like to absorb the vibrations so that rider may feel comfortable in riding, and further still maintain a high maneuverability.
  • One of those trucks is utilizing as many parts as ten assemblies in one truck which are complicate in assemble or disassemble.
  • the other type of the truck a U.S. patent No. 4,398,735, as shown in FIG. 6, is an integral truck 1, having a peg 64 having one end of which been connected to the truck 1 and the other end of which is either in contact with or adjacent to a center point along an axle hub 63 which is mainly functioned to prevent a beam 62 from deflecting.
  • the truck 1 may still deflect when a rider shifts his weight from one side to the other, since the peg 64 is standing on the axle hub 63 along.
  • the inventor has, therefore, invented this unitary skate truck which can solve such problems by integral injection molding of all the parts in a one piece unit to minimize vibratiob and still maintain its maneuverability.
  • FIG. 1 shows the present invention comprising an integral truck 1, having a beam 11, a cylindrical axle hub 111, and a curved plate 12 being integral injection molded.
  • the truck 1 is rigidly connected to the underside of a skateboard 2 by means of bolts 3 and nuts 31, and extending downwardly from one end thereof at angle to form the beam 11.
  • An axle hub 111 is formed at the other end of the beam 11 and extending perpendiculay thereto, and has an axle which may be molded therein with respective ends of which threaded for receipt of wheels 4 thereon.
  • the axle hub 111 has a larger diameter at its center portion and is gradually decreasing its size toward respective ends in such that the respective endmosts have the smallest size of all.
  • a lug 112 is formed at center portion along the length of the axle hub 111 and facing outwardly.
  • One end of the truck 1 opposing the end where the beam 111 is formed thereunder, has extending a portion downwardly and formed the arcuate plate 12 perpendicular thereto, and a recess 121 at the center portion along the length of the arcuate plate 12 facing outwardly at the location where the lug 112 is positioned within the recess 121.
  • the arcuate plate 12 is shaped in such that the middle has the most thicker portion and the thickness of the arcuate plate 12 is gradually becoming thinner towards respective ends, and at the respective endmosts of the arcuate plate 12 have the most thinner portion of all. Therefore, the clearance at the center portion between the arcuate plate 12 and the axle hub 111 has the smallest count whereas the clearance between the respective ends of the arcuate plate 12 in relation to the respective portions of the axle hub 111 have the largest count of all, as shown in FIG. 3A.
  • Such arrangement enables the trcuk 1 to be more flexible and more stability when a rider shifts his weight from one side to the other, as shown in FIGS. 4A, 4B.
  • the recess 121 of the arcuate plate 12 shall confine the movement of the lug 112 therewithin so that no matter how a rider is shafting his weight, the truck 1 will remain at center position constantly.
  • FIG. 5 refers to the beams 11' and arcuate plates 12 of the present invention being directly formed with a baseplate 5 of a roller skate.
  • the recess 121' of the arcuate plate 12' and the lug 112' of the axle hub 111' would function the same as they were formed with the skateboard.
  • the beam 11 absorbs part of the force from the rider's weight and vibrations from bumping road and constant twisting aand turning by bending inwardly, and the arcuate plate 12 has absorbs the rest parts thereof.
  • the recess 121 of the arcuate plate 12 has confined the movement of the lug 112 of the axle 111 therewithin so that the axle may remain at center at all times, regardless of the twisting, the turning or the like.
