Problems solved by technology

[0005] In view of the above-mentioned defects, the object of the present invention is to provide a sit-stand push-pull vehicle to solve the problem in the prior art that the user must rotate the sideways posture during the riding process, which causes the waist, shoulders, and neck to be easily fatigued, and the traditional technology Moderate users can only be easily fatigued by exercising the muscles of the feet

Embodiment Construction

[0032] Please refer to figure 1 , a sit-stand push-pull cart 60, comprising a vehicle frame 5, the front end of the vehicle frame 5 has a front wheel assembly 61 controlled by a handle 14, and the rear end of the vehicle frame has a rear wheel 8 driven by two one-way devices 7, 7a The rear wheel assembly 63, a swing device 68 is between the front wheel assembly 60 and the rear wheel assembly 63 of the vehicle frame, which drives a speed increasing device 25, and then passes through a unidirectional device 7, 7a comprising the above two The reversing mechanism 64 of driving rear wheel advances.

[0033] The swing device 68 includes a pedal 71, which is connected to a pedal arm 71a as a force arm, and its pedal arm 71a is connected to the vehicle frame 5 in a pivot 71b mode. Because of balance, the pedals 71 are in pairs Form; a moving seat 70, which connects a seat arm 70a as a moment arm, and its seat arm 70a is connected with the vehicle frame 5 in a pivot 70b mode; a linkag...

Abstract

A pulling-standing and pushing-seating vehicle which can be turned quickly and driven by hands through pushing and pulling, reduces the common hand-rowing scooter's design complexity of performing the functions of turning and power generating at the same time, separates the two functions through ameliorating the design of the counterforce part, and keeps the independence of the turning function. So the vehicle is simplified in structure and has the rowing function. The vehicle includes a turning device of common bicycle, a pedal, and a removable seat; the pedal and the seat have the arm of force respectively interacting with each other; an accelerator enlarges the travel, two ratchet wheels are driven and the vehicle is running forward as a result.

Description

technical field [0001] The sit-stand push-pull cart of the invention relates to a push-pull drive cart or a weight-driven cart. Background technique [0002] Usually, the handle of the push-pull driving car needs to do push-pull action and also need to do steering action, which makes its steering mechanism complicated. [0003] U.S. Patent No. 5192089 discloses a scooter for stepping on front and back. The scooter has a seesaw-type stepping pedal. The car is advanced towards the sprocket, and the two sides are respectively connected to the tail end of the chain with a spring to return. [0004] But in the above-mentioned technology, the user's feet must be operated one after another to step on the pedals, and both hands control the steering handle left and right, so that the user's body must rotate sideways, so the waist, shoulders, and neck are prone to fatigue and lose fun. In addition, the movement of stepping forward and backward only moves the legs, which is no differ...
