The specific embodiment

As Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4, step on the formula leisure body-building vehicle before a kind of, include a vehicle frame 10, hack lever 101 and back hack lever 102 before being provided with, it is sheathed mutually and go telescopic adjustment mutually, and can be positioning piece 1021 and set firmly combination; One side arm 20, see through rotating shaft 201 and be a left side, the right side freely swings shape pivot alive in vehicle frame 10 front ends, be installed on actuating device 21 and the front driving wheel 22 Gong trampling on it, this actuating device 21 is provided with spindle assemblies 211, and be installed on crank 212 respectively and on crank 212, be installed on pedal 213 in its rotating shaft 2110 both sides, one side is installed on a fluted disc 214, reach the fluted disc 214 corresponding fluted discs 215 that in the rotating shaft 221 of front driving wheel 22, are installed on spindle assemblies 21, and at two fluted discs 214, be connected with a chain 216 between 215, when stepping on pedal 213, this front driving wheel 22 can be driven lift-over; One seat cushion 30 is installed in vehicle frame 10, is available for users to take; A left side, right back runner group 40, be installed in both sides, vehicle frame 10 rear end respectively with the shape that freely swings, itself and front driving wheel 22 together support vehicle frame 10, runner 402 after its grade is pivoted with at least one with a back vent 401 respectively, these back vent 401 other ends are the bias voltage shape through tilting rotation pivot spare 403 and are hubbed on vehicle frame 10 rear ends, when the user is seated at seat cushion 30 and forces in vehicle frame 10, the rotation pivot spare 403 of this bias voltage location can be led through back vent 401 and be made back runner 402 do automatic guiding, the wobbling action of involution, between its grade and be pivoted and be connected with a connecting rod 41, swing that can be synchronous mutually; The leader 50, see through to rotate pivot spare 501 pivots alive at vehicle frame 10, can be for user's bimanualness of taking in seat cushion 30, and wherein, the pivot of living on rotation pivot spare 501 has an external member 502; One drive spindle 60, the pivot of living is connected between side arm 20 and the handle 50, can when pulling handle 50, cause side arm 20 and front driving wheel 22 synchronous turn to start, wherein, the one end is set in the external member 502 of handle 50, and set firmly by a locked assembly 601.

Utilize the above-mentioned basis that constitutes novel, cooperate Fig. 5 and shown in Figure 6 again, the three points of contact that sees through front driving wheel 22 and left and right back runner 402 cooperates, vehicle frame 10 will be firm, stable supported, the seat cushion that is seated at vehicle frame 10 30 that the user can be firm, safe also protracts both feet and places left and right pedal 213; Thereby, when both feet are stepped on left and right pedal 213, the transmission that sees through fluted disc 214,215 and chain 216 cooperates, this front driving wheel 22 will be driven lift-over and together be driven car body with left and right back runner 402 and be advanced, simultaneously, can hold up by user's both hands and to hold and free pulling handle 50 rotates, and cause drive spindle 60 interlocks cause side arm 10 and front driving wheel 22 turns in the lump, being seated that then user just can be easy, smooth and easy and safe drives, controls body-building vehicle.

Because this left and right back runner 402 is the bias voltage shape through tilting rotation pivot spare 403 and is hubbed on vehicle frame 10 rear ends, can do the action that freely swings of automatic involution, correcting when causing car body and advancing at any time, then when the user is seated at seat cushion 30 and implements to drive action and cause front driving wheel 22 lift-over, can not increase under the situation of beat carelessly of running resistance with this left and right back runner 402, nature, advancing, control just of this whole locomotive body can reach more smooth and easy, fast speed effect really.

In addition, utilize this front driving wheel 22 and a left side, right back runner 402 is three points of contact and is supporting vehicle frame 10, then the user not only can be firm, taking of safety in seat cushion 30, especially, with this left side that provides both feet to trample, right-hand tread plate 213 is located at side arm 20, causing needs both feet are operated in the mode of protracting after the user is seated at seat cushion 30, and this handle 50 is another with being located at vehicle frame with seat cushion 30, can be light after causing the user and being seated at seat cushion 30, comfortable pulling handle 50, and it is simple and easy to see through drive spindle 60 according to this, smooth and easy and fast speed controls side arm 20 and front driving wheel 22 turns to, then the user drives, control the form of this creation body-building vehicle, under unusual situation as the simulated race, with regard to the implementation of reality, obviously can reach the motor play of succulency and the purpose of body-building.Moreover, can do the wobbling action of automatic guiding, involution at any time with this left and right back runner 402, then along with front driving wheel 22 is driven directly lift-over and steering manipulation, this left and right back runner 402 will not only can cooperate cause car body smooth and easy, advance fast, especially, very fast and front driving wheel 22 turns to when big when the speed of a motor vehicle, and its grade more can be in the implementation of class that does not cooperate in the beat carelessly whipping action of seemingly driving a vehicle, fresh, entertaining that reaches that increase drives and game effect.

Cooperate shown in Figure 7 again, because the preceding hack lever 101 of this vehicle frame 10 and back hack lever 102 are made as sheathed mutually, and can go telescopic adjustment and mutually by positioning piece 1021 locking combinations, then in response to the user of different heights, this creation vehicle frame 10 can be regulated length in good time, freely, reaches to enlarge the purpose of using object.Certainly, be set in the external member 502 of handle 50 by an end of this drive spindle 60, and can be subjected to a locked assembly 601 locking location, then along with the length variations of vehicle frame 10, this drive spindle 60 can be the most appropriate length cooperate, make that the steering manipulation of side arm 20 and front driving wheel 22 is related to have an optimum efficiency.

Above-mentioned, this left side, right back runner 402 is except can advancing along with front driving wheel 22, and with automatic guiding, the wobbling action of involution drives and moves outside the car body, especially, the connecting rod 41 that connection is pivoted between its grade can cause mutual maintenance and swing synchronously, also there is essence to promote effect for the stability that drives driving, certainly, this left side, right back runner 402 can be implemented the synchronous swing that pins down mutually in view of the above, and can be not separately carelessly beat form resistance to displacement, when then car body is moved action by pulling enforcement backward, this left side, right back runner 402 can provide displacement smoothly, operate that also tool is simple and easy thereby make to move, convenience and fast speed effect.
