Abstract
The utility model provides a dual connecting foot pedal for a bicycle, which is suitable for refitting and using of weighted bicycles, mountain bicycles and lover bicycles and is composed of a series-wound foot pedal, a shunt-wound foot pedal or a front supporting foot pedal. The utility model is characterized in that foot pedal spindles which are connected with two cranks of a bicycle are connected with a front foot pedal and a rear foot pedal in a screw-threaded joint way by both ends of a coupling crank, and the foot pedal spindles on both sides of the utility model are respectively provided with connecting rod mechanisms through screw bolts for a clamping plate. A connecting rod with clamps is connected with a rear fork by a shaft pin, and a spring can be arranged on the connecting rod. Compared with the prior lover bicycle, the utility model has the advantages of compact structure, portability, agility, easy refitting, low price, etc.
Description
The utility model relates to the improvement of a kind of bicycle pedals mechanism---and duplex is foot-operated, is applicable to existing scale-up version and mountain bicycle, the foot-operated repacking of three-wheel vehicle are used.
Existing bicycle mostly is single rider, and a kind of " lovers' bicycle " of Shenzhen release at present can supply double rider, but because of adopting double-stranded bar, so complex structure and cost are higher.
The purpose of this utility model is intended to overcome above-mentioned the deficiencies in the prior art, and it is foot-operated to design a kind of bicycle duplex, realizes purpose double, that four-player is ridden, even single rider adopts the front-supporting type of this device foot-operated also very laborsaving.
The purpose of this utility model is such realization: it is foot-operated that the foot-operated minor axis lengthening parallel series that links to each other at left and right two cranks of former bicycle connects inside and outside (interior length, outer short) two, two ride all be arranged with axle sleeve, between be provided with sleeve pipe, the end is fixed with spindle nut.
The utility model also can adopt parallel connection to ride and realize.Promptly with foot-operated minor axis that two cranks link to each other on all be threaded by the coupling crank two ends before foot-operated and rear treadle, and with bolt connecting rod mechanism is installed by clamping plate respectively at the foot-operated minor axis place of its both sides, the connecting rod of tool clamp is connected on the back vent with pivot pin.
The utility model also can adopt the foot-operated structure of front-supporting type to realize.Promptly with foot-operated minor axis that two cranks are connected on by preceding support crank end be threaded one foot-operated.If also can connect when changing pedal spindle into foot-operated major axis last inside and outside two foot-operated.
Owing to adopted said structure, one people firmly steps up and down during rider, another people then pedals forward to form and make a concerted effort, reach reinforcement, labor-saving effect (radius growth when need are exerted oneself, turning round need not exert oneself the time then reduced radius).Particularly adopt two kinds of structures of aftermentioned, since the arm of force increase, make when scrunching the revolution of track ovalize, not only laborsaving, have also that stand for a long while can effect.The utility model " lovers' bicycle " has advantages such as compact conformation, light, repacking is easy, cheap flexibly.If it is foot-operated that lovers' car is changed this duplex, just can ride for four-player, operation power is doubled.This duplex is foot-operated also to scrunch the occasion of use applicable to need, as goes into the power waterwheel and install and use.
Below in conjunction with accompanying drawing in detail it is described in detail.
Fig. 1 is the foot-operated structure diagram of the utility model series connection.
Fig. 2 is the utility model foot-operated structure diagram in parallel.
Fig. 3 is the foot-operated structure diagram of the utility model front-supporting type.
Code name implication among the figure: support crank before foot-operated 5 sleeve pipes 6 (interior) foot-operated 7 left crank 8 coupling cranks 9 clamping plate 10 minor axises 11 foot-operated track 12 connecting rod pivot pins 13 springs 14 clamps 15 of 1 foot-operated major axis 2 spindle nuts 3 axle sleeves 4 short (outward)
Embodiment one: with reference to Fig. 1, install on the left and right crank of former bicycle in special foot-operated major axis 1, the series connection thereon foot-operated 6 and short foot-operated 4 (than foot-operated 6 short 1/3 length), they with axle 1 contact position all be equipped with axle sleeve 3, between sleeve pipe 5 (being about 20mm) also is installed at interval in order to avoid hit pin, the end is fixed with double nuts 2.Series connection foot-operated.Cooperate for stepping on both feet, the stand post on the former car should change the outfit and go up the flat seat post, makes front saddle reach 150-200mm place fixing, and rear cradling (or seat cushion) is located at low level flat seat post or is fixing above the clothes hanger.Back rider both hands are held and are installed in curved post place top high 200-250mm (wide about 200mm) removable T type or annular handrail gets final product.The stage casing of handlebar is crooked slightly forward in addition, and the distance of increase and front saddle makes the center of gravity reach.About rider need not slide, for safety is advisable up and down with " dead car ".
Embodiment two: referring to Fig. 2, the foot-operated minor axis 10 that adopts former bicycle to link to each other with two cranks, by inside and outside two clamping plate, 9 usefulness bolts coupling crank 8 and connecting rod mechanism are fixed on it, all be threaded last forward and backward two foot-operated 6 at the two ends of coupling crank 8 (as being about 240 * thick 10mm), connecting rod mechanism is connected flat bar by vertical rod with connecting rod pivot pin 12 and forms, and clamp 14 usefulness pivot pins are installed on the back vent.Connecting rod mechanism is provided with spring 13, and making it that tool stands for a long while can effect, and connecting rod mechanism plays balance, directional tagging.Dotted line shows forward and backward foot-operated 6 path of motion, ovalize among the figure.All the other technical requirementss are with embodiment one.
Embodiment three: with reference to Fig. 3, and substantially with embodiment two, support crank 15 before only on former bicycle pedals minor axis 10, installing, and all only install one in its end and ride 6.Preceding support crank 15 is provided with connecting through hole, position changeable when being connected with connecting rod mechanism.This structure is particularly suitable for being installed on the manual tricycle and uses.If foot-operated 6 change the outfit and become ride major axis 1, can become tandem foot-operated, the double rider of confession.
