(2) the first pedal assembly 5 is made to be in folded state.That is: touch the upper side of bolt rod 52 from outside to inside with sole, bolt rod 52 upper compression top spring one 52d, make the lower end 52c of bolt rod 52 depart from the second lock-joint.Then, while small size driven forward first pedal assembly 5, sole slowly turns to the rear end of the first pedal assembly 5 from the upper side of bolt rod 52, driven forward again, the first pedal assembly 5 is made to overcome the first torsion spring 55 resistance, the arc edge side slippage forward that the lower end 52c of bolt rod 52 is fan-shaped along right angle, until lower end 52c snaps in the first lock-joint 54a, completes folding.(this state is called in the following text " state B to be used ")
2, from " state B to be used " to the operating mode of using state
(1) the dull and stereotyped 53a of oblique pin is first jammed on gently, make oblique pin 53 overcome top spring two 53b resistance to move downward, the lower end 52c of jack-up bolt rod 52 and depart from the first lock-joint 54a, under the effect of the first torsion spring 55, the first pedal assembly 5 is made to reset to " state A to be used " (i.e. state shown in Fig. 2).
(2) the first pedal 51 is stepped on.Now, connecting lever 71 makes crank arm 73 rotate clockwise an angle, crank arm sleeve pipe 73a makes again to dial line bar 74 level and turns over an angle, thus make draught line 75(adopt brake cable) to front haulage, tractive force transmits drop on sprocket wheel 82a through draught line 75, adaptor union 75d, chain 75e, make middle support 8 rotation, the performance supporting role until support wheel 84 lands, and realize " halting " object.Now, lock dog 51b snaps in latch hook 63a, locks the first pedal assembly 5.Thus make whole device by " state B to be used " to " state A to be used " again to the transformation of using state.
3, from using state to " state A to be used " again to the operating process of " state B to be used "
(1) the second pedal 61 is gently stepped on, make the second armstand 63 around anchor shaft 65 rotation angle downwards, latch hook 63a is made to depart from lock dog 51b, under the extension spring 72 of connecting lever 71 acts on, first pedal assembly 5 resets to state to be used (i.e. state shown in Fig. 2), now, dials line bar 74 and moves backward under the effect of tensioning spring 75c, make thread-laying mechanism be in relaxed state, middle support 8 under the effect of himself extension spring upwards rotation to highest point.This device is returned to " state A to be used " from using state.
(2) from " state A to be used " to the operating process of " state B to be used ", see the operation of " state B to be used ".
See Fig. 4, when run into blow out time, middle support 8 can be put down, under the state not stepping on the first pedal assembly 5, button 86b is pulled in pull-up, more firmly steps on and pedal pin 86d, telescopic pin 86a is under the effect of the 3rd torsion spring 86c, and inside automatic lock in the bottom of vehicle frame 1b1, thus supports 8 in locking.Then make grab 83a snap in the 83b1 of card division guiding clamping plate 83b rear end is carried, recover the bidirectional rolling function of support wheel 84, to facilitate implementation.As above two kinds of functions removed by needs, contrary operation.
In addition, as can be seen from Figure 4, pedal the rear that pin 86d is positioned at support wheel 84, equal to increase the power arm pedaling pin 86d, vehicle body is propped and becomes lighter.
Notice:
When 1, will use this device, before stepping on the first pedal, first should reduce the speed of a motor vehicle to the slowest, when vehicle body does not tilt, front and back wheel is braked and is stepped on the first pedal and operates simultaneously, and the distance that support wheel tows on ground is shorter, stops more steady.
2, because the wheel footpath of ratchet is less, left and right ratchet limited separation, so road surface that is too rugged or that tilt forbids to use this device.
3, in a state of use, also can make three-wheel vehicle and use, but will slowly advance, and the using skill of three-wheel vehicle will be learned.
Above-described embodiment is only and invention thinking of the present invention is described, and should not be considered as the concrete restriction to structure of the present invention, any simple deformation design done by embodiment, all should include protection scope of the present invention in.
