Wherein: F: footwear grillage, Fi: footwear grillage interior plate, Fo: footwear grillage outer panel, P: pedal, Sp: elastic support member, Ap: pedal shaft, Ca: control arm, Wf: front wheel, Af: front wheel wheel shaft, Gi: spragging gear, Sif: front spring, Bif: preceding inboard block, Bf: positive stop, Gb: the back is to braked wheel, and Ab: the back is to the braked wheel wheel shaft, and Ob: the back is to braked wheel wheel shaft chute, Bm: middle block, Gc: forward direction braked wheel, Ac: forward direction braked wheel wheel shaft, Oc: forward direction braked wheel wheel shaft chute, Wr: rear wheel, Ar: rear wheel wheel shaft, Sir: rear spring, Bir: the inboard block in back.

Below in conjunction with the detailed description of accompanying drawing, provide a most preferred embodiment.

Use is ridden instead of walk before the Skateboard, and the Skateboard of must will riding instead of walk is bundled on the pin, or adds attached vamp on the footwear grillage of the Skateboard of riding instead of walk, and the Skateboard of will riding instead of walk is through on the pin tightly.

The Skateboard of riding instead of walk does not allow to slide backward.With reference to accompanying drawing 1, when sliding backward, front wheel " Wf " clockwise rotates, also clockwise rotate with the coaxial spragging gear " Gi " of front wheel " Wf " this moment, thereby drive with the back of spragging gear " Gi " engagement and rotate counterclockwise (with reference to accompanying drawing 4), and its axle " Ab " is upwards slided along chute " Ob " to braked wheel " Gb "; So, the circle wheel of back on braked wheel " Gb " contacts with positive stop " Bf ", arrive the upper end of chute " Ob " when axle " Ab " after, the back will stop the back to rotate counterclockwise to braked wheel " Gb " to the circle wheel of braked wheel " Gb " and the frictional force between positive stop " Bf ", thereby stop front wheel " Wf " to clockwise rotate, make sliding and stop backward.Be the action effect of assurance positive stop " Bf ", positive stop " Bf " and the angle of back about the upward round contact-making surface of taking turns of braked wheel " Gb " should become 75 to spend with chute " Oc ".

When strong, when flat road surface slides forward, people always step a pin earlier and (are called the forward foot in a step) forward, and adopt forward foot in a step heel to land the gait that lands behind the forward foot in a step sole earlier.When forward foot in a step heel at first lands, pedal " P " is subjected to downward pressure, flexible member " Sp " is compressed, control arm " Ca " is shaken clockwise, the projection of control arm " Ca " front end stretches to the middle part of chute " Oc " forward, make the position of axle " Ac " in chute " Oc " of forward direction braked wheel " Gc " remain on chute " Oc " lower end, the circle wheel on the forward direction braked wheel " Gc " does not contact with middle block " Bm ", and the rotation forward of pulley " Wf " is uncontrolled.Like this, when forward foot in a step sole also lands, the forward foot in a step just can body support to front slide.The heel of another pin (rear foot) lifts subsequently, correspondingly, the pressure that pedal " P " is subjected to disappears, flexible member " Sp " stretches, control arm " Ca " is shaken counterclockwise, the projection of control arm " Ca " front end is return the middle part of leaving chute " Oc " backward, and the axle " Ac " of forward direction braked wheel " Gc " can be slided up and down in chute " Oc ".At this moment, the leg thrust of back ball of foot will make front wheel " Wf " clockwise rotate, and this rotates drive forward direction braked wheel " Gc " and rotates counterclockwise, and make its axle " Ac " be in chute " Oc " lower end; Simultaneously, this rotates and also to drive the back and rotate counterclockwise to braked wheel " Gb ", and the result is prevented from the rotation of pulley, and leg thrust produces impulse force forward, promote health under the support of the forward foot in a step to front slide.At last, before the rear foot is marched toward, become the forward foot in a step in next action.

When sliding downwards on the clivia road surface, the palm lands simultaneously before and after the both feet, and is the outer splayed step (toes turned outward) to downslide.At this moment, pulley also is subjected to lateral thrust laterally when rotating, spragging gear lateral surface before making in the wheels and preceding internal stop " Bif " friction, pulley lateral surface in the back wheels and back internal stop " Bir " friction, thereby the velocity of rotation of pulley before and after slowing down.Like this,, change the side-thrust that pulley is subjected to, just can control and adjust the downward sliding speed of Skateboard by adjusting the step shape of both feet.

When suddenly towards on walking, or during stair activity, the sole of the forward foot in a step lands earlier.At this moment, pulley " Wf " desire rotates counterclockwise and makes the Skateboard of riding instead of walk to front slide, but because forward foot in a step heel does not land, pedal " P " makes the front end projection of the control arm " Ca " that is installed in the pedal front end leave chute " Oc " under the support of flexible member " Sp ", so, the spragging gear " Gi " of pulley " Wf " drives forward direction braked wheel " Gc " and clockwise rotates, and axle " Ac " is upwards slided in chute " Oc ", the circle wheel of forward direction braked wheel " Gc " contacts with middle block " Bm ".As a result, axle " Ac " is when sliding into the upper end of chute " Oc ", and the circle wheel of forward direction braked wheel " Gc " and middle the retaining certainly friction between " Bm " will stop the rotation of pulley " Wf ", and the Skateboard slip forward of riding instead of walk is terminated.Subsequently, the forward foot in a step heelstrike, pedal " P " is subjected to downward pressure, flexible member " Sp " is compressed, control arm " Ca " is shaken clockwise, the projection of control arm " Ca " front end stretches to the middle part of chute " Oc " forward, makes the axle " Ac " of forward direction braked wheel " Gc " be in the upper end of chute " Oc ", guarantees that the braking of forward direction braked wheel " Gc " is reliable.Like this, the sole and the heel of the forward foot in a step land simultaneously, and body support does not slide, and at this moment, the another pin just can lift and step forward or going up or down stairway.

When prevailing roadway is walked, both can adopt manner of walking, also can adopt the mode of sliding to walk.
