Abstract
The utility model discloses a foldable bicycle with a front-mounted handlebar and small wheels. A vertical bar of a handlebar of the utility model presents a sleeve shape, an inserting bar and a forward-tilting bar form a handlebar adjusting bar, and the inserting bar are matched with the vertical bar; a transverse frame of the handlebar is positioned at the front upper side of a front shaft, and a folding joint point is positioned on a crossbeam of a bicycle frame. The structure can lead the transverse frame of the handlebar to keep away from a bicycle saddle, and therefore, under the condition without lengthening the crossbeam, moving space for human legs is enlarged, conditions for further reducing the size of a folded bicycle body are created, and the utility model can be used by adults by using baby carrier wheels and a bicycle crossbeam.
Description
The utility model relates to the improvement of cycle frame.
In order to make bicycle be easy to carry and receive and keep not riding the time spent, Folding Bicycle has appearred.This bicycle can make volume-diminished by bus, when train, steamer, vehicle body is folded up, be convenient to transportation and deposit, carry, so this car dwindles the volume (or length) of each parts in design as far as possible, as the employing little wheel of trying one's best, short as far as possible car beam.But similar to child's bicycle after the too short BMX (Bicycle Motocross) of car beam is launched, handlebar not only influences the motion of restriction leg, can't ride, and makes nature of the upper limbs posture utmost point, and is uncomfortable.The handlebar of existing bicycle constitutes by vertical rod and crossbearer, and vertical rod is affixed with the front fork that front-wheel is housed, the affixed crossbeam in upper end, vertical rod and front fork all have one by the front lower place to back upper place bevelled angle.As want that the BMX (Bicycle Motocross) (diameter is below 0.46 meter) that children are used supplies the adult to ride usefulness, must strengthen the vertical rod height of handlebar.But because of vertical rod is tilted to the back upper place, the handlebar vertical rod is high more, and is then more close to the vehicle seat position, and handlebar and vehicle seat distance further and be unfavorable for that more the adult rides usefulness.Add the method for long vehicle beam (crossbeam) as employing, will inevitably strengthen the volume (or length) after folding.Therefore this problem is the difficult point place that influences the further reduced volume of folding bicycle.
The purpose of this utility model provides the collapsible small-wheel bicycle of a kind of handlebar forward type, the bar that leans forward of this car handlebar stretches to car the place ahead, the affixed handlebar crossbearer of its front end, make the crossbearer position away from vehicle seat, the length of car beam is equaled or near carriage for children, adopt the steamboat of diameter below 0.46 meter, can cosily ride usefulness for the adult, the existing folding bicycle of volume ratio after making it folding is littler.
For achieving the above object, the utility model is taked following design plan: make with the vertical rod of front fork bonded assembly handlebar to be cannula-like and to be provided with pin-and-hole, a handlebar adjust bar that is made of the inserted link and the bar that leans forward is set, the inserted link external diameter of this adjust bar and vertical rod internal diameter coupling also are provided with pin-and-hole, the pin-and-hole that connects inserted link and vertical rod with pin or its substitute, the bar that leans forward stretches to car the place ahead, the crossbearer of its front end and handlebar is affixed, its junction is positioned at front axle the place ahead, also promptly by the place ahead 5-50 centimetre of perpendicular line that front axle draws, folding node is located on the crossbeam of vehicle frame.
The collapsible small-wheel bicycle of the utility model, its handlebar are provided with the handlebar adjust bar that is made of lean forward bar and inserted link, and its bar that leans forward stretches to car the place ahead, and the front end of the bar that leans forward is positioned at before the front axle, and the crossbearer that makes handlebar is away from vehicle seat.Like this, just strengthen cyclist's motion space of leg again, avoided crossbearer to hinder the both legs motion, adapted to both arms length.The length of wheel diameter and car beam is equaled or, adopt the steamboat below 0.46 meter near carriage for children, can for the adult comfortable ride usefulness.Existing folding bicycle, though also dwindle the volume after folding as far as possible, want bondsman's leg that enough motion spaces are arranged after considering expansion, greatly beam length must with become the person bicycle crossbeam approaching, used wheel is for well matched with it, can not littler (more than 0.46 meter); The utility model newly overcomes the restriction of this difficult point, makes crossbeam and wheel footpath all bigger dwindling can be arranged, and can contract to 0.45-0.3 rice in the wheel footpath, so its existing folding bicycle of volume ratio after folding is little, can pack in the general traveling bag, carries.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model
As shown in Figure 1, the collapsible small-wheel bicycle of this handlebar forward type, the vertical rod 4 of its handlebar 1 is connected with front fork, vertical rod 4 is cannula-like and is provided with pin-and-hole, a handlebar adjust bar 3 that is made of the inserted link and the bar that leans forward is set, the inserted link external diameter of this adjust bar is with vertical rod internal diameter coupling and be provided with pin-and-hole is connected inserted link and vertical rod with pin 5 or its substitute pin-and-hole, the bar that leans forward of handlebar adjust bar stretches to car the place ahead, the crossbearer 2 of its front end and handlebar is affixed, its junction is positioned at the place ahead of front axle, (the place ahead that refers to vertical line that front axle draws) 5-50 centimetre, the crossbeam 6 that folding node 7 is located at vehicle frame is little.The vehicle seat of this car is identical with existing steamboat or folding bicycle, and the vehicle seat inserted link 9 of vehicle seat bottom can insert within the cant beam 11 of back, by catch gear 10 lock bridges.The handlebar adjust bar of this car can be by taking off (taking out pin 5 gets final product), the height of scalable handlebar when the inserted link of adjust bar is provided with a plurality of pin-and-hole in the vertical rod 4.As install hinge between adjust bar 3 and vertical rod 4, then handlebar is foldable to desired area.In order to solve wheel too hour, the crank lower end is overhead too near, and the problem that influence is used can place the axis 8 that main crank is installed the top of front axle and rear axle line.The handlebar adjust bar can break away from vertical rod for convenience, plays the effect of folding harvesting, can be provided with elastic opening in the upper end of vertical rod 4, and install catch gear at this place.
