Definitions

  • the subject invention is related to an anti-reverse sliding mechanism which comprises a pair of carriers having a plurality of movable anti-reverse sliding plates disposed therein.
  • the anti-reverse sliding plates may move to a sliding position or an anti-reverse position.
  • an anti-reverse action will be produced, and said action will convert to a forward sliding force.
  • a reaction force for moving forward is obtained by applying a force on an acting surface (or object) in opposite direction.
  • a driving force to move forward is obtained due to the center of gravity of the skater's body which inclines forward and the alternating actions of the skates.
  • oars, ski sticks, and legs are used respectively to apply forces backward to obtain the reaction forces needed to move forward.
  • the driving force to move forward is obtained by means of the gradient of a slope, or the sliding effect resulted from the actions between the skater's forwardly inclining body weight and the ground surface.
  • the mechanism comprises a pair of carriers having a plurality of movable anti-reverse sliding plates disposed therein.
  • the sliding plates serve as a low friction sliding medium as they move to a forward sliding position.
  • a reaction force which may convert to a forward driving force may be obtained.
  • Another object of the present invention is to provide a sliding carrier which may be used to walk up a slope.
  • a sliding carrier 1 similar to a ski.
  • the bottom of the carrier 1 presents a smooth surface 11.
  • the smooth surface 11 includes a frame 16 at the center thereof.
  • a plurality of anti-reverse sliding plates 13 linked to one another are disposed within the frame 16.
  • the anti-reverse sliding plates can move as a unit to a horizontal position to present a sliding surface (A).
  • a smooth surface is formed at the bottom of each carrier 1 as a result of the combination of the sliding surface (A) and the smooth surface 11 (see Fig. 4).
  • the sliding plates can be swung as a unit to a vertical position. In this orientation, each of the sliding plates which stands vertically protrudes beyond the smooth surface 11 so that an anti-thrust surface (B) is formed underneath the sliding carrier 1 (see Fig. 5).
  • the anti-reverse sliding plates 13 are disposed within the rectangular frame 16 which is provided within a slot 17 of the sliding carrier 1.
  • the slot 17 is provided with a plurality of discharge openings 12 which are corresponding in number to the anti-reverse sliding plates.
  • the discharge openings 12 penetrate through the top of the sliding carrier 1 so that snow, soil, water, etc. entering the slot 17 through the bottom of the sliding carrier 1 can be expelled through the discharge openings 12.
  • Fig. 6 shows a second embodiment in accordance with the present invention.
  • This embodiment is different from that of Fig. 3 in that a foot retainer 10 in which the feet of an user may be placed is further provided on the sliding carrier.
  • Figs. 7 and 8 are cross-sectional views illustrating the internal structure of a portion of the embodiment in details.
  • the foot retainer 10 is provided on a force applying lever 18.
  • One end of the lever 18 is pivotally connected to a connecting rod 14 by means of pivot points 19 and 20.
  • the anti-reverse sliding plates will swing to a vertical position from its original horizontal position. In other words, the original sliding surface (A) turns into the anti-thrust surface (B).
  • the anti-reverse sliding plates 13 at the bottom of the sliding carrier 1 may turn to present the sliding surface (A) or the thrust surface (B) in accordance with the changes in directions of reaction forces.
  • the smooth surface will interact with the engaging surface under the action of sliding friction to produce effective, forward driving force.
  • the gravitational acceleration will cause the user with the sliding carriers to slide down the slope continuously, and thus the anti-reverse sliding plates will remain unchanged in the state of presenting the sliding surface.
  • the unit of anti-reverse sliding plates will act as a thrust surface as it engages the ground and provide the thrust force for the user to walk up the slope.
  • Each of the anti-reverse sliding plates 13 can be linked to one another by a link so that the plates may act as a unit and move uniformly. As shown in Figs. 4 and 5, an elongated connecting rod 14 is used to link each of the plates 13 at the top thereof. Consequently, as an external force is applied on the plates 13, all the plates 13 will move in unison to the horizontal or vertical positions to present the sliding or thrust surfaces (A), (B) respectively.
  • each of the anti-reverse sliding plate 13 is pivotally connected to the frame 16.
  • the pivot 15 is positioned adjacent to the smooth surface 11 so that as the anti-reverse sliding plates move to present the sliding surface (A), there will be no difference in height between the sliding surface and the smooth surface (11).
  • Figs. 9 and 10 show another modified embodiment of the present invention.
  • a plurality of guide fins 3 are provided at the bottom of the sliding carrier.
  • the guide fins are disposed parallel to the sliding direction and project slightly beyond the bottom of the carrier so as to prevent the carrier from sliding sideways.
