Abstract
The utility model relates to a bicycle with foldable handlebars and pedals, in which a handlebar can rotate singly and freely, pedals can be foldable, and thus the space occupied by the utility model during parking is reduced. The utility model is characterized in that the handlebar is in shaft sleeve type connection with a front fork pole, and the rotary shaft of the pedal is in sleeve type connection with the hollow shaft of the crank sleeve of the pedal. When the utility model is used, the handlebar is rotated to be perpendicular to the plane of the bicycle body of the utility model and is locked, the pedals are unfolded, and thus the utility model can be used; when the utility model is parked, the handlebar is rotated to be on the same plane with the bicycle body, and the pedals are folded into the plane of the bicycle body; thus, the occupied space of the utility model is reduced, and the parking is convenient.
Description
The utility model relate to a kind of handlebar and stretcher collapsible, the bicycle that is taken up space in the time of reducing bicycle storing.
Existing ordinary bicycle, handlebar is that fixed type is connected with preceding crutch, stretcher can not fold.The bicycle of selling on the market is this form.Such bicycle handle bar and stretcher are perpendicular to the car body plane and stretch out 2~3 the car body thickness in car body plane, cause bicycle take up space to increase the space of 2~3 times of bicycle volumes than actual volume; And now disclosed various foldable bicycle operation is comparatively complicated, and bicycle globality and steadiness descend, and influence in-use performance, are difficult to penetration and promotion.
Task of the present utility model provides a kind of improved bicycle, its handlebar and stretcher can simple rotation and are folding, thereby shared space when reducing bicycle parking makes parking of bicycle convenient, do not influence simultaneously the functions of use of bicycle again, and operation is also very simple.
Task of the present utility model is finished as follows: the handlebar 6 with centre hole 7 is by handlebar slide core 8, banking stop 10 and hold-doun nut 12 and by preceding crutch 1, the common handlebar support that constitutes of handle post 2 handlebar fixed core 3, handlebar S. A. 4 and bolt of rear end plate (5) is male connection, has the stretcher S. A. 20 of locating part 21 and is connected for telescoping with hollow shaft 16 in its crank 14.Handlebar adopts movable the connection with preceding crutch, handlebar can rotate to separately with car body in same plane; Stretcher may be folded in the car body plane, is reduced to 1/2~1/3 when folding thereby bicycle is taken up space, and becomes more regular global shape, so just reached the purpose that convenience is parked.The utility model is easy to use, and is simple to operate, when adopting the foregoing description structure, the car load packing of the convenient transportation of bicycle realization dispatched from the factory, and the back of unpacking can be used immediately without any need for assembling.
Fig. 1 is a partly three-dimensional exploded view of the utility model handlebar.Fig. 2 is the cutaway view of handlebar when position of rotation.Fig. 3 is the cutaway view of handlebar when latched position.Fig. 4 is the three-dimensional exploded view of stretcher fixed part.Fig. 5 is the movable planar view partly of stretcher.Fig. 7 is the stretcher assembling section.Block diagram when Fig. 8 is the stretcher stretching, extension.Fig. 9 is the block diagram of stretcher when folding.Figure 10 be bicycle taken up space when stretching overlook design sketch.Figure 11 is the design sketch of overlooking that is taken up space behind the bicycle folding.
Divide handlebar and two parts of stretcher below with reference to accompanying drawing, be described in further detail by embodiment of the present utility model.
One, handlebar is with reference to Fig. 1, the bearing part of handlebar is by preceding crutch 1, handlebar rest 2, handlebar fixed core 3, handlebar S. A. 4 and bolt of rear end plate 5 constitute jointly, handlebar slide core 8 profiles are identical with handlebar fixed core 3, handlebar slide core 8 centre holes 9 are enclosed within on the handlebar S. A. 4, handlebar slide core 8 can rotate freely around handlebar S. A. 4, the size of handlebar 6 centre holes 7 is identical with the outside dimension of handlebar fixed core 3 and handlebar slide core 8, handlebar 6 can be enclosed within on handlebar fixed core 3 and the handlebar slide core 8 by hole 7, and when handlebar slide core 8 alignd with handlebar fixed core 3, handlebar 6 can move up and down and be enclosed within respectively on handlebar slide core 8 or the handlebar fixed core 3.The size of banking stop 10 is greater than hole 7, aperture in the banking stop 10 is with the aperture of washer based nut 11 and hold-doun nut 12, and equal the diameter of bolt of rear end plate 5, be enclosed within the root of bolt of rear end plate 5 when banking stop 10, and when tightening washer based nut 11 and hold-doun nut 12, banking stop 10 will limit handlebar 6 at vertical direction and make it can not deviate from outside the handlebar core.
With reference to Fig. 2, when handlebar 6 is enclosed within on the slide core 8, rotation handlebar 6, handlebar 6 can rotate around S. A. 4 together with slide core 8, and does not influence the direction of handlebar rest 2.
With reference to Fig. 3,, will drive handlebar rest 2 and rotate when handlebar 6 is enclosed within when rotating on the fixed core 3, and the direction of decision bicycle front-wheel, slide core 8 is turned to the position of staggering with fixed core 3, but just in the vertical direction pins handlebar 6, makes it and can not deviate from from fixed core 3.When handlebar 6 when bicycle body is in same plane, just reduced the shared space of bicycle, conveniently park, as shown in figure 11.When handlebar 6 directions when being vertical with car body, bicycle can normally use, as shown in figure 10.
Fixed core 3 among this embodiment, handlebar centre hole 7 and slide core 8 are square, as adopt criss-cross, when star or complicated shape such as petal, can improve effect handsome in appearance greatly, as use with the length and width of banking stop 10 measure-alikely, and the height additional accessory identical with slide core 8 is when replacing slide core 8, handlebar 6 can be locked with fixed core 3, and its result of use is just identical with ordinary bicycle.
Two, stretcher is with reference to Fig. 4, the crank of pedal cranks 13 ends overlaps 14 two ends pearl groove 15, and after hollow shaft 16 was inserted in crank cover 14, two ends steel ball 17 was inserted pearl groove 15, constitute the ball hollow bearing by pearl mouth 18, the fixedly position of pearl mouth 18 of hold-doun nut 19 is used at hollow shaft 16 two ends again.
Stretcher S. A. 20 middle parts fluted 26, by screw 22 steel wire limit spring 21 is fixed in the groove 26, referring to Fig. 6, fix bonded assembly stretcher 25 of S. A. 20 is Jiong shape, after stretcher S. A. 20 is inserted in the hollow shaft 16, can slide in hollow shaft 16, both sides have limit spring 21 and washer based nut 23 respectively, hold-doun nut 24 restriction sites, assembly drowing is seen Fig. 7, when stretcher trailed, as shown in Figure 8, limit spring 21 made stretcher be in normal use location.When needing to fold, only need press limit spring 21, stretcher S. A. 20 can overlap in 14 at crank and be free to slide, as shown in Figure 9.
With reference to Figure 10, Figure 11, visible the utility model is at the remarkable contrast effect of folding front and back.
