Description

The pedal support for bicycle device

Here relate to a kind of additional device that is used for bicycle, be contained in the down foot-operated of either side, make people's temporary term stop onboard.

Bicycle is decided car a kind of method preferably of can yet be regarded as when the crossing temporary term stop that red light is arranged.The people needn't get off like this, starts also soon, and it is not facile that 2 of acrobatics formula decide car.Feasible method is to increase a new strong point when stopping.The easiest is cyclist one heel brace ground.But vehicle seat must be put lowlyer than ideal height like this.Knee is lifted too highly when riding, uncomfortable and fatiguability.Device with a kind of vehicle seat of lifting at random can overcome this shortcoming.In patent specification CN86108460, reflection is arranged.Even if but like this, still have quite a few people not adopt; Vehicle seat has been put into lower limit, and tiptoe only reluctantly, is difficult to keep stable support.

Existing a kind of perambulator, each fixes the support of a foot wheel its trailing wheel both sides, can make car upright when stopping.Because supporting can not folding, and the turning of car and crossing ability are affected.Take up an area of too wide when depositing.Bike stand on existing adult's car, folding in advance.If use as deciding car, palpus solves the problem of the strong point by the back and the middle folding of advancing.

Draw the invention task thus: obtain a kind of support that can folding and unfolding in advancing, the strong point should be near the axis of bicycle, and its manipulation should make things convenient for, and can use on existing several bicycles, and not influence the performance of former car.

The scheme of characteristic has solved this task in the claim 1.

When the crank of bicycle is in the position that is equivalent to clock 5 to 6 point ranges,,, just crank can be stabilized on this position in conjunction with holding brake if the leg of this side is stretched.This moment, crank was nearest apart from ground, and the support on foot-operated has been owing to utilized growing of crank to become very short so that can folding under foot-operated, when support was opened, its touchdown point was far away relatively from car, was favourable to deciding the stable of car.

Here accompanying drawing in conjunction with the embodiments illustrates its details.

Fig. 1 is contained in the stand for bicycle outward appearance under riding.

Fig. 2 is the stand for bicycle sterogram of actuator with the leverage.

It is foot-operated down that this stand for bicycle can be contained in either side, with the left side for well.The base 9 of stand for bicycle is fastened on the central siphon 13 by clevis bolt 11 and nut 8.Return chain during use earlier, left foot outwards slides in returning chain process, and pushing lever 1 makes it rotate around axle 2, promotes connecting rod 3 and supports 5, supports 5 around pivot pin 6 rotations, leans against after opening on the stop 10; At this moment hold brake, centre of body weight stretches left leg slightly to moving to left, and will ride on the position that is stabilized in level of approximation with sole.After car stopped, support 5 pedal spindles with bicycle, crank, axis held on people, car, remain on erectility.

Right crus of diaphragm is exerted oneself forward earlier when resetting, the slow then lock of loosing one's grip, and left foot inwardly breaks away back.Support 5 and under spring 4 effects, reply, just can normally exercise.

From preventing to support the angle of 5 unstability inflection when deciding car, support 5 angles of opening back and base 9 formation with greater than 90 ° between 100 °～110 ° for well.

Support 5 version, no matter single armed still is a double-arm can both be used.Can stop foot-operated rotation after the both arms support lands, single support then needs to come balance with pin.But single support structure is simple, and weight is lighter.

For crank 12 can stably be parked between hour hands 5～6, both arms can be supported by the one arm lengthening of nearly trailing wheel, not exceed crank 12 plane degree of being.Foot-operated plane will turn forward when deciding car like this, and pin has one to make crank 12 component backward downwards when pedaling, and it is parked on the position that needs.

Castor is preferably all loaded onto in no matter single armed or both arms support, avoids that supporting drags along the ground when landing scrapes.Support 5 among Fig. 2 is adjustable, changes the correspondence position that supports leading portion 14 and hole 15 by screw 16, just can have the change of level to support 5 length.Do like this is in order to adapt to the crank difference in length of different trade mark cars in the same type.

Above-mentioned stand for bicycle is a kind of basic structure, and the driver train that supports 5 is changed, and just can obtain the stand for bicycle of other type, to adapt to different processed edges.

Use elbow-bar mechanism to drive the stand for bicycle embodiment that supports.

Toggle link 1 and 3 and the movement relation that supports have been described among Fig. 3 a.Fig. 3 b is the situation that parts are settled on base 9.With itself and Fig. 2 more as can be seen major part axle 6, base 9, to support 5 changes little, significantly change just moves down axle 2 positions.Support 5 open after, the center line coincidence of axle 2 center lines and connecting rod 3 is on the straight line parallel with base 9, mechanism can self-locking like this.For this state is kept, the structure that the contact in toggle link 1 and 2 has adopted Fig. 3 c to show, in the use should cross the centre line in the hinge-point center of two bars.The excentric sleeve 37 of rotary supporting shaft 2, coupling mechanism force that can adjusting mechanism is seen Fig. 3 b.This mechanism can self-locking, and bar 1 arm of force can extend, and therefore operation is comparatively light.With the pin touching lever 1 that makes progress, spring 4 will support 5 and pack up during return.

Fig. 4 makes the stand for bicycle sterogram of actuator with gear.

Tooth plate 36 and gear 35 engagements among the figure, support 5 is fixedly connected with gear 35, is that rotate around base at the center with axle 6, and angle is against on the base by support 5 heads and controls.After removing the power on the tooth plate 36, be supported on inflection under the action of the spring (the figure medi-spring is not painted).

Support 5 in this example can be regarded the both arms support of being out of shape as.Change castor 7 is fixed on the position in the prong, can adjust and support 5 length.The cantilever 34 of band uvula can keep the difference of height of castor 7 and steamboat constant.Castor 7 increasings are to clad wheel rim for the ball bearing of main shaft of packing into materials such as utilizing rubber among the figure.To improving its service conditions and upgrading is favourable.

Further developing of stand for bicycle is to increase the device that locking is supported.Be on the stand for bicycle of actuator with lever, gear, pin can not leave the pass and take into account two foot-operated tasks of balance by pine before support lands, and requires coordination.Lock the back this action be broken down into two the step finish.Promptly open switch earlier in returning chain process, it is foot-operated then pin to be adjusted to best position balance.

The sterogram of Fig. 5 latching device

When support 5 was opened, drivening rod 3 and axle 29 slided in the elongated slot of base 9.The head of axle 29 lifts and crosses angular lever 31.Lever 31 resets under the effect of spring 4, spring hook 33.At this moment lever 31 leans against on the shotpin 32, stops axle 29 to be return, and also promptly supports 5 and is locked.At this moment pin can be by leaving on the switch.With the afterbody of side impact lever 31 in the pin, axle 29 is released during release.Support 5 and pack up under spring 4 effects, connecting rod 3 is got back to initial position.

This installs simplified operation, increases the reliability of deciding car.

Fig. 6 and Fig. 7 make the stand for bicycle of actuator with gear and piston crank mechanism.

The essential part of this scheme is still formed the hinge structure of living by base 9, support 5 and axle 6.Actuator links to each other with support 5 by pull bar 3.Stand for bicycle no longer changes with pin by gear 22 drives.Gear 22 is garden finishing bevel gear cuters, is contained in pedal spindle 25 roots.The interior hole shape of its section and gear 22 is seen Fig. 8.Figure middle washer 24 is between gear 22 and bearing cap shim.Uvula on the packing ring withstands on axle 25 flat sides' the step, prevents with the passing of time gear 22 plaies.Fig. 6, file is repaiied uvula gear 22 is on the appropriate location during assembling, prevents gear 22 and shaft-cup friction.

Since during rotating crank 12, foot-operated also rotation.Then gear 22 is for being contained in foot-operated base 9 down, and the static and gear 22 of visual base 9 is in rotation.Therefore available it make driving wheel and drive the gear 21 that is contained on the base 9.Gear 21 also is a finishing bevel gear cuter, and diameter is big than gear 22.This two-wheel back lash can be adjusted by the fixed block 17 under central siphon 13 by filing or pad.Gear 21 only has the gear teeth in a smaller part garden on week, and redundance cuts, in order to avoid 28 backhauls of overslaugh slider pin.These cingulums move crank pin 19, crank 18 and slide block 26 and move back and forth between guide plate 20 and base 9.When two end positions of slide block 26, the tooth of gear 21 and gear 22 break away from.Slide block 26 can not driven by gear 21 in this zone, supports 5 and will remain on the position of packing up or putting down.At this moment ride and can freely swing, not relevant with gear 22.Make and support 5 these two states reverses, gear 21 must be rotated a low-angle to the engagement direction, gear 22 will be to rotating in the opposite direction with former side simultaneously.Here the situation that is used in combination describes.Fig. 7 shows that supporting 5 has put down support ground, and the spring 4 on the crank 18 is against guide plate 20 tops and is bent accumulation of energy.Revenue and expenditure supportted 5 o'clock, rode forward.Gear 22 is just changeing, and supports 5 beginnings overhead.Spring 4 promotes connecting rod 18, rotates by crank pin 19 driven gears 21, with gear 22 engagements of rotating.Gear 21 is driven continues rotation, and it is flat that crank pin 19 promptly will support 5 receipts by connecting rod 18, slide block 26, pull bar 3.Crank pin retreats to from gear 22 the most nearby, and crosses base 9 line of centerss.Gear breaks away from gear 22 for 21 this moments.The weight of support 5 abuts against gear 21 locking on the slider pin 28 that has returned, can not reverse under vibrations, causes and supports 5 saggings.

When deciding car, return chain earlier, promote lever 1, cable wire 30 traction drag hooks 27, drive, make gear 21 and gear 22 engagements of reversing returning pin 23 inhours of drawing close drag hook 27 with pin.When crank pin 19 moved back line of centers and went to end position shown in Figure 7, gear 21 is jump out of mesh again, and this moment, spring 4 was put aside the required energy of backhaul.

Smooth when gear is meshed at first, the tooth at gear 21 two ends is lengthening slightly preferably.In addition in the foot-operated counterweight that adds of the offside that stand for bicycle is housed, with the foot-operated weight in balance both sides.

Embodiment among the application makes with common material, and possessing general punch process ability can make.

After using stand for bicycle, the number of times of getting on or off the bus be can reduce, muscle power and time saved; Reduce the bicycle floor area, parking density can be strengthened.Owing to needn't slide during starting, strengthen the carrying capacity in highway section to a certain extent.

As a kind of bicycle accessory, when being its device, its biggest advantage need not do any change to former car.Turning and rideability there is not influence yet.
