Abstract

The utility model discloses a ground gliding and body-building device simulating the surfing sport, which is a small flat plate vehicle composed of a pedal, a back fixing wheel, a front driving mechanism, a tail auxiliary wheel and other main components. People only need to stand on the pedal for the front and back pedaling movement and the front driving device adopting a rocking rod and slide block mechanism and a steel rope driving system can drive the wheels to enable a surf-board playing on land to advance with front and back undulation in a wave type and conduct various trick movements. The utility model can be used on flat and hard fields, easily mastered by beginners and favored by the teenagers.

Description

Self-walking skate-board with wheels

The utility model is a kind of ground taxi body-building apparatus of simulating surfing.

Why can mannedly slide at the popular Surf-board playing on land of America and Europe in recent years is to glide in special athletic ground (as slope, curved surface bend etc.), or adopt human body the mode that ground scrunches to be advanced to proceeds posterolateral, therefore, limited carrying out of this motion to a certain extent.

The utility model is intended to create a kind of new model that needn't scrunch ground, with the motion mode that rises and falls and advance wave upon wave before and after the simulation surfboard is on wave, stand in by human body and to step after its pedal is gone forward, drive wheel Surf-board playing on land is slided forward, and can do grandstand play such as turning.And, when moving forward, the gravity center of human body just in time becomes positive correlation with direction unanimity, the speed that Surf-board playing on land advances, and the user grasps easily.Surf-board playing on land is applicable to smooth strong place such as cement flooring, asphalt surface etc., especially easily carries out in the area that vast skating, drought skating fan are arranged.

Surf-board playing on land is the truck (seeing accompanying drawing) that is made of critical pieces such as pedal, back fast pulley, front driving mechanism and afterbody accessory whorls voluntarily.

Pedal (1) is the strip bent plate made from nine layers of glued wood, and guard strip (2), (3) all are equipped with in the front and back end.

The fast pulley sub-assembly is equipped with at the rear portion of pedal (1), its base (4) is a rectangular bottom, four jiaos porose, connect with pedal (1) with bolt etc., hind axle (6) two ends of being fixed in base (4) axis hole respectively connect the bearing (5) of two parafacies to assembling, in order to clamp roller (7), fixed with spring washer, nut again.Roller (7) adopts polyvinyl chloride or rubber to make.

Driving mechanism is equipped with in the front portion of pedal (1), and it is by slider-rocker mechanism, compositions such as steel wire rope transmission system and one-way clutch.The bottom of bearing (8) is triangular in shape, and three apertures are arranged, and connects with pedal (1) with bolt etc.Rocking bar (10) sees from the bottom surface and is rectangle that respectively there are two axis holes the front and back end, and its rear end axis hole is with the axis hole of little axle (9) with bearing (8), and torque spring (23) is hinged, and making rocking bar (10) can be center of circle swing with the bearing axis hole.Rocking bar (10) front end axis hole is hinged with front axle (13) and connecting rod (11) rear end axis hole, and the centre of front axle (13) also is fixed with the output sleeve of one-way clutch (14).Two relatively clamping rings (12) of assembling respectively are equipped with at the two ends of front axle (13), in order to clamping a front-wheel (15) identical with roller (7), and are fixed with spring washer, nut.The front end axis hole of connecting rod (11) is equipped with a pulley spindle (17), and this hinged wire rope pulley (18) also penetrates in the stopper slot, and slide in front and back therein.Stopper slot (16) divides two of left-right symmetry, and the bottom is elongated, and three apertures are respectively arranged, and is fixed in the front end of pedal (1) with bolt etc.The slider-rocker mechanism of Zu Chenging converts anterior the moving up and down of pedal (1) front-rear reciprocation movement of pulley spindle (17) in stopper slot to thus.

Pedal (1) is equipped with fixedly end seat (19), (20) at steel wire rope two ends between base (8) and spacing truss (16), steel wire rope (21) from end seat (19) initial as the accompanying drawing with counter clockwise direction reel bull wheel (14) groove a few, and certain some stator bull wheels (14) rooved face in the middle of the steel wire rope, angle pulley (18) then, walk around sliding tightening with the front end of tension spring (22) by (18) groove in a clockwise direction and connect, the rear end of tension spring (22) connects with end seat (20) again.The steel wire rope transmission system finally passes to front-wheel (15) with the driving force of pulley spindle (17) in reciprocating stroke by one-way clutch (14), front axle (13).

In addition, at the afterbody of pedal (1) the accessory whorl sub-assembly is housed also, the bottom of its base (24) is rectangle, and four jiaos porose, connects with pedal (1) with bolt etc.Accessory whorl (26) is hinged with accessory whorl axle (25) and base (24) axis hole, and accessory whorl (26) cylindrical is waist 6) hinged with accessory whorl axle (25) and base (24) axis hole, accessory whorl (26) cylindrical is dolioform.When the anterior perk of Surf-board playing on land, accessory whorl can land and slide and the fixing wheels three-wheel tripartite confrontation together in back, grandstand play such as do turning, swing to that sliding reposefully also can lead.As because of special requirement, also the accessory whorl assembling and dismantling can be removed.The material of accessory whorl can be identical with roller (7).

Drive principle: phase I, when standing on the pedal, the user gravity center of human body moved on to the back fast pulley after a while the time, the pedal front portion will be upturned, preceding wheels are because the reset response of gravity and torque spring (23), downward with rocking bar (10), the rear is to swing, pulling connecting rod (11) makes pulley spindle (17) move on to the back extreme position by the preceding extreme position of stopper slot, by pulley (18), the variation of bull wheel (14) position affects steel wire rope also to affect bull wheel and one-way clutch (14) as rotating in a clockwise direction among the figure, do not transmit moment of torsion because of this direction of one-way clutch, front axle (13) is not subjected to this direction torsion.Second stage, the user needs the gravity center of human body is moved forward, the front portion of pedal is depressed, before wheels with rocking bar (10) upwards, the place ahead is to swing, connecting rod (11) heads on pulley spindle (17) and shifts preceding extreme position onto by the back extreme position of stopper slot, and steel wire rope affects to opposite direction of phase I, therefore affects bull wheel and one-way clutch (14) as counterclockwise rotating among the figure, this direction of clutch is transmitted moment of torsion, drives front-wheel (15) and rolls forward.So perseveration rises and falls the Surf-board playing on land front and back and advances wave upon wave.

For make top grade voluntarily Surf-board playing on land also can change the steel wire rope transmission system into chain drive system, and pulley (18), bull wheel (14) are made into sprocket wheel and get final product.

The utility model compared to the prior art, its advantage is that type of drive is rationally light, the sport dynamics performance is good, and is strong to place adaptability, stamping parts is adopted in design morely, is convenient to make and with low cost, is a kind of physical fitness and the good utensil of riding instead of walk.
