Abstract

The utility model discloses a paddling bicycle. The tripod, the front fork, the back fork, the front wheel, the back wheel, etc. of the common bicycle are used. The transmission device is completed by that a dynamic rocker whose supporting point is fixed to the tripod is connected with a chain to drive a fly wheel, and the other end of the chain is connected with a return rod. The method that the foot pedal does circumferential movement to drive the bicycle to run is changed and replaced by hand to control the rocker to do reciprocating movement. The force of the whole body is coordinated to make riders have the feeling of floating on the water by boat, and on the basis of walking substitution, the aims of body-building and entertainment are realized.

Description

Rowing bike

The utility model relates to a kind of rowing bike

Ordinary bicycle is a kind of running vehicle easily, its transmission all is to adopt the moving driven sprocket of pedal drive chain dribbling to move in a circle to finish since coming out, generally only brought into play its kinetic energy of riding instead of walk, since its both hands only controlling party to handgrip, both feet only scrunch stretcher, and the trick self-movement is unfavorable for the coordination performance of whole body strength, and do not have shock absorption device, take uncomfortable.

The purpose of this utility model is exactly the transmission device that changes bicycle, allows the trick coordinated movement of various economic factors, is convenient to whole body strength and gives full play to.

The utility model purpose is achieved in that rowing bike comprises spider, front fork, back vent, front-wheel, trailing wheel of ordinary bicycle etc., its driving device is that the power rocking bar that fulcrum is fixed on the spider links driving chain, chain drives flywheel, flywheel drives trailing wheel, chain one end links the return bar, return bar one end is fixed on the support, pull back spring one end hook hanging bracket spacing hole, and the other end is hitched return bar bottom.At the front fork of rowing bike direction is set and scrunches control front-wheel direction, simple and easy cartridge type spring damper is set at front fork, back vent.

The rowing bike of making according to the utility model, utilize two-hand control power rocking bar to drive cycle racing, utilize both feet control direction of traffic, be convenient to the coordination performance of whole body strength, shock absorption device is set, increase traveling comfort by bike, cyclist's this car whole body of riding is loosened, float sensation in the water of skiff is arranged, and the purpose of body-building and amusement is played in each position coordination.

Below in conjunction with accompanying drawing in detail embodiment of the present utility model is described in detail.

Figure one is a structural representation of the present utility model;

Figure two is a return bar backsight direction structure scheme drawing;

Figure three is the front fork structure scheme drawing;

Figure four is an A enlarged drawing among the figure three;

Figure five is the back fork structure scheme drawing.

With reference to figure one, figure two, figure three, figure four, figure five, rowing bike comprises spider 4, front fork 2, back vent 6, front-wheel 1, trailing wheel 7, adjustable seat 5, feet 11, and driving device, driving device are that power rocking bar 3 lower ends that fulcrum 13 is fixed on the spider 4 link driving chain 9, chain drives flywheel 8, flywheel drives trailing wheel 7, and chain 9 other ends link return bar 10 lower ends, and return bar upper end is fixed on the horizontal fork 12 of trailing wheel, pull back spring 14 1 end hooks hang in the horizontal fork of trailing wheel 12 spacing holes, the other end is hitched return bar bottom, and front fork 2 horizontal ends stretch out to both sides and form Pedalling 15, at front fork, be provided with simple and easy cartridge type spring 16 dampings in the back vent, interior cartridge regulating block 17 is adjusted the elastic force size, specifically can pitch downside at front fork two simple and easy cartridge type springs are installed, and back vent then adopts a simple type spring.For realizing the whole body damping, the horizontal fork 12 of trailing wheel connects with triangular frame 4 employing activities simultaneously.In addition, also brake gear can be installed, the front and back brake is handled and is adopted external member to be fixedly mounted on power rocking bar 3 handgrips, and the transmission of power adopts guiding principle silk drag-line to realize.Thereby this car relies on both hands to draw or promotes rocking bar 3 crank motions drive chain powered vehicle and moves ahead, and its speed is by the reciprocating speed control of two-hand control rocking bar, and its direction is controlled by both feet.

Claims (3)

1. rowing bike, comprise spider, front fork, back vent, front-wheel, trailing wheel etc. and driving device, it is characterized in that: its driving device is that the power rocking bar that fulcrum is fixed on the spider links driving chain, chain drives flywheel, flywheel drives trailing wheel, and the chain other end links the return bar, and the return bar other end is fixed on the support, pull back spring one end hook hanging bracket spacing hole, the other end is hitched return bar bottom.
