The specific embodiment
The utility model proposes a kind of pedal type body-building vehicle, it comprises that vehicle body 1 and pivot are installed in the front and back wheel 3,4 of this vehicle body 1, described vehicle body 1 front end is pivoted with one rotationally and drives the handlebar 2 that front vehicle wheel 3 turns to, wherein, also can respectively be pivoted with a pedal drive mechanism and on the both sides vehicle body 1 of described rear wheel 4 tops can be driven driving the elastic recovery formula transmission device of rear wheel rotation by described pedal drive mechanism, and the two ends of described transmission device are arranged in described pedal drive mechanism respectively.
In order further to understand concrete structure of the present utility model and course of action, below conjunction with figs. and specific embodiment the specific embodiment of the present utility model is described in further detail.
As shown in Figure 1 to Figure 3, the front portion of the pedal type body-building vehicle of present embodiment (comprising front-wheel 3, handlebar 2 and vertical rod etc.) can be identical with known bicycle, gives unnecessary details no longer one by one herein.The difference of itself and known bicycle is, the rear end of the both sides vehicle body of pedal type body-building vehicle of the present utility model (back vent 10) respectively obliquely upward one be extended with a support 11, the other end of this support 11 is articulated with the pedal drive mechanism of fork-shaped, and this fork-shaped pedal drive mechanism comprises that a treadle 111 that has pedal 112 reaches and this treadle 111 fork 113 at an angle; Described elastic recovery formula transmission device includes chain 21 and extension spring 22 (shown in Fig. 4 B), one end of described extension spring 22 can be fixed near the pivot of described vehicle body 1 and fork configuration, its another termination is established described chain 21, described treadle 111 is provided with a tension wheel 115, the wheel shaft 41 of described rear wheel 4 is provided with a flywheel 24, is connected in the end of fork 113 after described chain 21 meshes with aforementioned tension wheel 115 and flywheel 24.In addition, for guaranteeing the enforcement and the use of present embodiment, from the pivot center of fork configuration, the radius that arrives tension wheel 115 outer rims is preferably less than the radius to the terminal connection of fork chain.
Being provided with unidirectional driver element between described flywheel 24 and the wheel shaft 41, as ratchet or roller type overriding clutch, being not limited in this certainly, also can be the free-wheel clutch of other kind.As user during with the downward pedal 112 of pin, chain 21 will drive flywheel 24 forward rotation, at this moment, can drive wheel shaft 41 and rotate, thereby this pedal type body-building vehicle is advanced forward, and this extension spring 22 is stretched gradually; And when the user unclamps pedal (exerting oneself) no longer downwards, the restoring force of this extension spring 22 makes chain 21 drive flywheel 24 backward rotation, at this moment, make the two separation by flywheel 24 in the unidirectional driver element of 41 settings of wheel shaft, thereby rear wheel 4 can continue to rotate forward, the body-building vehicle art skating.
In the present embodiment, as shown in Figure 1 to Figure 3, the fork-shaped pedal drive mechanism of this pedal type body-building vehicle is articulated in the outside of two back vents 10 of vehicle body 1.
Shown in Fig. 4 A, pedal type body-building vehicle with said structure, be positioned at reference position (treadle approximate horizontal) when locating at pedal, the total length of this chain 22 and spring 21 is the shortest, at this moment, extension spring 21 is in original pre-tensioning state, when the user firmly tramples downwards, when driver train is rotated, this extension spring 21 constantly extends, until arriving the ultimate position shown in Fig. 4 B, at this moment, the total length of this chain 22 and spring 21 reaches the longest, extension spring 21 is in maximum energy accumulating state, in case the user stops the application of force to this pedal, then the elastic-restoring force of extension spring 21 will produce a moment, make pedal drive mechanism reset to reference position.So left and right sides pin constantly repeats to trample, and this pedal type body-building vehicle is constantly moved ahead.
Shown in Fig. 5 A, present embodiment is provided with equally by treadle, pedal, spring, fork, flywheel and tension wheel etc. are formed pedal rod driving mechanism and transmission device, its difference identical with embodiment 1 is the back pronged shape of vehicle body and the structure and the set-up mode of treadle, wherein, the pivot end of two pedal drive mechanisms of this pedal type body-building vehicle is positioned at the inboard of two back vents 10 ', the outside respectively lateral bending of the end with pedal 112 of described treadle 111 ' is established and is open shape, described two treadles 111 ' are " eight " word shape (shown in Fig. 5 B) are set, and its space from end is in the outside of described back vent 10 '.Under step on when motion, the pivot end of this treadle is between two back vents 10 ' and rear wheel 4 that extend described vehicle body 1 rear end always, in order to guarantee to use two treadles 111 ' and corresponding pedal 112 can be smoothly back vent part 10 ' by the vehicle body lower end, and can not produce interference, described two treadles 111 ' are established in the outside lateral deviation of an end with pedal 112, so that the distance of the two end is greater than the spacing of two back vents, thereby avoid the back vent 10 ' of vehicle body 1 can trample downwards the time.Putting before this, the back vent 10 ' of these vehicle body 1 two sides also can be established by correspondingly outside respectively lateral bending, and tension wheel 115 is arranged on the inboard of two treadles 111 ', shown in Fig. 5 B, so, makes fork, flywheel and tension wheel still can be in same plane.Said structure more helps producing and the use safety.In the present embodiment, vehicle body back vent and hind axle are fixing with nut and mandrel, and the working process of pedal 112, chain and the spring of present embodiment is consistent with embodiment 1.In the present embodiment, as shown in Figure 6, its vehicle body is collapsible, conveniently to collect and to carry.
As Fig. 7, shown in Figure 8, be another embodiment of the present utility model, agent structure wherein comprises pedal drive mechanism and transmission device, can be identical with embodiment 1, Gu Tuzhong no longer is repeated in this description.And it shows a kind of different body styling, and its body drawing becomes another kind of folding mode, is provided with at the middle part of vehicle body to make before and after it two parts folding structure that pivots, and with folding placement the when not using, conveniently collects and carries.Because can be used for folding structure of the present utility model is known technology, no longer describe in detail herein.
Though the utility model has utilized aforementioned specific embodiment to disclose in detail; right its is not in order to limit the utility model; anyly have the knack of this skill person; in not breaking away from constructional feature scope of the present utility model; when doing various changes and modification; for example can substitute aforementioned extension spring and adjust corresponding mounting means by flexural spring, can realize the utility model equally, therefore protection domain of the present utility model is as the criterion when looking claims person of defining.
