The specific embodiment

Below in conjunction with the drawings and specific embodiments the present invention is further elaborated.

With reference to Fig. 1, Liftable type strut (1) and taper blade (2) adopt the light material of high strength, high rigidity and excellent stability to make.The threaded one end of Liftable type strut (1) connects strut handle (5), and the other end is threaded with the outer end face of taper blade (2).The centre of strut is designed to the sleeve-type lifting mechanism, being connected and fixed of mechanism adopted my another invention, name is called " a kind of mechanical means that is fixedly connected and device thereof ", number of patent application is 02107291.4, use this device that is fixedly connected (4) can make Liftable type strut (1) change length, making stick type oar collection sweep and scull is one, is applicable to that the people of different heights uses with a kind of oar, is applicable to that also same individual adopts different support appearances.Liftable type strut (1) is threaded with the outer end face of taper blade (2), and the interior cone angle of taper blade (2) is changeable, generally selects 60 °-120 °.The angular bisector of interior cone angle overlaps with the extended line of strut (1) axial line, when the angle of the extended line of strut (1) axial line and the water surface is 45 °, interior cone angle is selected 90 °, because what at this moment taper blade (2) fell into water is that part of just in time vertical with the water surface, the resistance of striking this moment is big, thereby ahead power is also big; When the angle of the extended line of strut (1) axial line and the water surface was 30 °, interior cone angle was selected 120 °, and reason is the same.Interior coning angle number selected, the number of degrees that depend on the angle of strut and the water surface help supportting the oar most under what situation the person has an effect, and this will could select the best by test of many times.The inner top surface of taper blade (2) is made spherical shape, and its diameter is identical with the diameter of ball float (3), both fully coincidence place cement with the seccotine of not being afraid of water logging.Ball float (3) is made with extremely light fabulous rubber, has for gas filed aperture; The size of ball float (3) immerses can quick rebound in the water with ball float and is as the criterion, and is principle not influence the time of carrying oar.When striking, that part of resistance that runs into water that taper blade (2) falls into water, consequent antagonistic force is main ahead power.Undoubtedly, taper blade (2) falls into water partly many more, and the resistance that runs into water is big more, thereby application force is big more, and ahead power is big more.And when the power of striking was excessive, ball float (3) can be submerged, and ball float (3) can run into the resistance of water equally, and a part of antagonistic force wherein pops up ball float, and another part antagonistic force then becomes the power that the person of striking advances.

With reference to Fig. 9, from the different angle of manufacturing process, two kinds of performances of taper blade (2) are divided into two, keep taper blade (2) and make the open circles taper, its linkage function is born by coupling bar (14).One end of coupling bar (14) is made cylinder, is fixedly connected with Liftable type strut (1), and it is spherical that the other end is made open circles, and bonding with ball float (3), both sphere diameters are identical; It is coniform to make solid around the coupling bar (14), and its coning angle is identical with the taper blade (2) that remains, is fixedly connected between the two.In order to increase the bond area of ball float (3) and coupling bar (14), an end of coupling bar (14) can be made the hollow hemisphere shape, though improved bonding firm degree like this, negative effect is arranged also, has promptly increased the weight of stick type oar, and influence is little fortunately.Except that said structure, other structure all first embodiment with stick type oar is identical, does not describe in detail at this.

With reference to Figure 10, bonding half of ball float (3) and taper blade (2) made three-dimensional coniform, and both coning angles are identical.Its purpose is to strengthen being fixedly connected of ball float (3) and taper blade (2); Can also under the identical condition of bond area, alleviate the weight of stick type oar; Simultaneously under the size of taper blade (2) and all identical situation of angle, keeping taper blade (2) to fall into water under the part unmodified prerequisite, strengthen taper ball float (3), just can increase buoyancy; Perhaps under the constant and isogonal situation of buoyancy, the area of dehiscing of taper ball float (3) is reduced.Except that said structure, other structure all first embodiment with stick type oar is identical, does not describe in detail at this.

With reference to Fig. 2, Fig. 3, Fig. 4, Fig. 5, the surfboard supporting with stick type oar also adopts the light material of high strength, high rigidity and excellent stability to make.Stream line pattern is made in the front portion of surfboard, to reduce the water resistance that surfboard runs into.The head of surfboard is upturned, and also is stream line pattern, in case suppressed by wave when cleaving through the water.The plane of surfboard up, be provided with two kinds of soles in the center of gravity position of board plane: a kind of is spill sole (7), promptly vertically be arranged side by side the sole shape at surfboard, fall into the into certain degree of depth of board plane, the thickness that the degree of depth surpasses general sole gets final product, and support oar water skier can barefoot or wear footwear and step on into spill sole (7), just can utilize the condition that all is blocked of pin all around, with the direction of the double control of ankle surfboard, and can firmly stand on the surfboard; For more firm, special middle front part on the spill sole is provided with movable footmuff (6), and its available elastic cord is made, and also can adopt and exempt from cingulum (velcro); The both sides of movable footmuff (6) are fixed on the both sides of spill sole (7).Another kind is an embedding formula sole (8), and sole is made respectively except that toe-cap

Font is fixed on the longitudinal plane of surfboard side by side, and toe-cap is towards the working direction of surfboard; Support oar water skier wears the shoes of " worker " font sole, when these two kinds of sole activities are embedded in a time-out, supports the oar water skier and just firmly stand on the surfboard; Further pin is fixed on the surfboard if desired,, can be provided with at the heel place of embedding formula sole (8) and exempts from cingulum so that do various highly difficult actions.The size of surfboard is kept afloat with a year individual and is as the criterion.The surfboard that contest is used must be unified size.

With reference to Fig. 6, Fig. 7, Fig. 8, be provided with movable sole (9) in the center of gravity position on surfboard plane, its front portion is connected with the top movable of support pin (12), and its rear portion and rudder blade direction lever (11) are fixedly connected; Support pin (12) and surfboard thread connection; Rudder blade (10) flexibly connects with the bottom of support pin (12), is fixedly connected with rudder blade direction lever (11); Rudder blade direction lever (11) and fluted disc (13) engagement; On the movable sole (9) various uppers of a shoe are set, the safety binding person's of striking pin.In order to strengthen rudder blade (10) in stability unmanned or direction when jolting severely, can be on rudder blade (10) and support pin (12) flexibly connect, or be nested with cylindrical spring with rudder blade direction lever (11) place of being fixedly connected at rudder blade (10); Or indicator clip above the nut at the place that below support pin (12) and surfboard, is fixedly connected, the other end of spring leaf be pressed in rudder blade (10) above.When surfboard need be turned, only need move movable sole (9) and get final product, ankle moves after carrying earlier when mobile, and a mobile tooth is turned little, and mobile bidentate is turned bigger, and the rest may be inferred by analogy, and the mobile direction and the direction of turning are antithesis.Utilization activity rudder blade on turn slows down can be minimum, even can not slow down.

Surfboard also can be provided with fixedly rudder blade or not have rudder blade, and this kind situation will lean on the motion of stick type oar or ankle or both in conjunction with the line of travel of controlling surfboard, and on turn slows down bigger.
