Below in conjunction with drawings and Examples, the present invention is described in detail.
Consult Fig. 2, Fig. 3 and Fig. 4, the preferred embodiment of surfboard steering hardware of the present invention is applicable to be installed on a surfboard 2.This surfboard 2 has a plate body 21, and one can promote the power unit 22 that this plate body 21 advances.This plate body 21 has the first 23 and plate tails 24 of a contrary plate.This power unit 22 is a jet dredge pump that draws water that is installed on these plate tail 24 belows, and has opening water outlet 25 backwards.
This surfboard steering hardware comprises a steering unit 3, driver element 4 and a gear unit 5.This steering unit 3, comprises that a pivotally connected set is located at the fair water sleeves 31 of this water outlet 25, and this fair water sleeves 31 can be guided this water (flow) direction that water outlet 25 flows out, and then adjusts the working direction of this plate body 21.
This driver element 4 comprises that a pedestal that is fixedly arranged on this plate head 23 41, one are hubbed at interlock dish in this pedestal 41 42, one along a driving axial D and are hubbed at this drivings 43 and along the driving bearing 45 that self extends axially the flexible actuating arm 44, that expose to this pedestal 41 and be arranged at 44 of this pedestal 41 and this actuating arms along the spacing driving seat that is fixedly arranged on this interlock dish 42 of this driving axial D 43, vertical this driving axial D in edge, and a handgrip 46 that is fixedly arranged on these actuating arm 44 ends.
Consult Fig. 4 and Fig. 5, this actuating arm 44 is arranged in this driving bearing 45 and axially can not reverses in fact along self, and has a flexible tube wall 441, and several length directions along this tube wall 441 extend and interval is embedded in the cable wire 442 in this tube wall 441.In the present embodiment, this tube wall 441 is quality of rubber materials, and described cable wire 442 is respectively multi-strand steel cord.Self cannot to reverse be completely best condition to this actuating arm 45 in theory, but in real world, this actuating arm 45 has torsional deflection slightly unavoidably, no matter this case studying carefully, and this slightly distortion in this case context be not to reverse, and should meet the not coilable context of this case.If want one of standard still to belong to the tolerable scope of good operation, be approximately that the opposite end of this actuating arm 44 is less than 5 degree along self axial torsional deflection tolerance.
Be understandable that, cable wire 442 of the present invention also can be respectively one-strand rope.
This handgrip 46 in the form of a ring, and has a hand-holding segment 461 and a linkage section 462 that is arranged at this actuating arm 44.Self of the end of vertical in fact these actuating arm 44 contiguous handgrips 46 of this hand-holding segment 461 is axial.
Consult Fig. 2, Fig. 3 and Fig. 4, this gear unit 5 is arranged at this interlock dish 42, and can drive this fair water sleeves 31 rotations according to these interlock dish 42 rotations.This gear unit 5 comprises that one is fixedly arranged on this plate body 21 and is actively located in the transmission rope 52 of this transmission sleeve pipe 51, and is arranged at respectively an active steering bar 53 and a driven deflecting bar 54 of 52 liang of end opposite of this transmission rope by transmission sleeve pipe 51, one that this plate head 23 extends to this plate tail 24.These active steering bar 53 ends are hubbed at this interlock dish 42, and these driven deflecting bar 54 ends are hubbed at this fair water sleeves 31.
Consult Fig. 3, Fig. 6 and Fig. 7, while generally advancing, this fair water sleeves 31 is approximately parallel to this water outlet 25, operator can stand on this plate body 21, utilize this power unit 22 that water suction the current that sprayed by this water outlet 25 and this fair water sleeves 31 are promoted to this plate body 21 and advance, grip the hand-holding segment 461 of this handgrip 46 to keep whole gravity balance simultaneously.
In the time of need to turning to, operator only need be gripped on this hand-holding segment 461 and along this actuating arm 44 self this handgrip 46 of axial rotation, this this actuating arm 44 of handgrip 46 interlocks is rotated along a rotation direction (as shown in arrow R2 in arrow R1 and Fig. 7 in Fig. 6) around self axis, just can drive this driving seat 43(to see Fig. 4) this interlock dish 42 of interlock rotates along this rotation direction around this driving axial D, thereby pull this active steering bar 53, and this active steering bar 53 is by this driven deflecting bar 54 of these transmission rope 52 interlocks, can drive this fair water sleeves 31 along rotating in contrast to this rotation direction.
The angle of controlling 25 of this fair water sleeves 31 and this water outlets by this handgrip 46 of rotation changes, and makes to be guided by this fair water sleeves 31 via the flow direction of this water outlet 25 ejections, and then controls this plate body 21 and advance along this rotation direction.
Generally speaking, the present invention utilizes this actuating arm 44 to be deflected and not coilable in fact characteristic, operator only need to just can control these plate bodys 21 by this gear unit 5 along this actuating arm 44 self this handgrip 46 of axial rotation and turn to, significantly reduce the amplitude of fluctuation of operator's health, therefore be not easy to affect operator's gravity balance, and there is the effect that improves operability, moreover, this actuating arm 44 can be deflected along with operator's action conversion, compared to known rigidity, drive Control arm to have and preferably control degree of freedom, can also further increase operability, really can reach creation object of the present invention.
It is worth mentioning that, gear unit 5 of the present invention is except adopting the disclosed Machinery Control System of this preferred embodiment, can also adopt wireless signal control system, utilization can be responded to the inductor of these interlock dish 42 anglecs of rotation and direction, by the anglec of rotation with transmitting radio signals to the receptor being arranged on the beat motor of this fair water sleeves 31, and control beat motor to drive this fair water sleeves 31 to carry out angle beat, thereby control this plate body 21, along the hand of rotation of this interlock dish 42, advance.
