Breaststroke-type man-powered massaging cart

Abstract

The invention discloses a breaststroke-type man-powered massaging cart which comprises a handle frame, a front fork rod, a branching head, two rear frames, a pedal, front wheels, rear wheels and a braking assembly. The front fork rod is connected to the middle of the handle frame, the branching head is connected with the front fork rod, the two rear frames are pivoted to two sides of the branchinghead, the front wheels are pivoted to the front fork rod, the rear wheels are pivoted to the two rear frames respectively, the braking assembly is matched with the rear wheels, the rear frames include bearing portions at the front ends and supporting portions at the rear ends, the bearing portions upwards incline at a certain acute angle with respect to the advancing direction of a cart body, thepedal is installed on the bearing portions, the rear wheels are installed on the supporting portions and are universal wheels, and the installing faces of the rear wheels and the supporting portionsupward incline at certain obtuse angles with respect to the advancing direction of the cart body. Therefore, the breaststroke-type man-powered massaging cart is pedaled by a user, the pressure produced by human body to the cart body has a component force in the advancing direction of the cart body, and then a thrust force making the cart body to advance can be produced through cooperation of opening and closing movements performed by the human body to the two rear frames so as to make the cart body advance.

Description

technical field [0001] The invention relates to a scooter, in particular to a frog-style human-powered massage car which can be advanced by using the twisting of the human body itself. Background technique [0002] At present, the frog-style human massage car has been widely used as a kind of exercise and fitness equipment. As the Chinese patent No. 200320128036.5 announced on January 12, 2005, a kind of frog-style human massage car is disclosed. A handle frame is set, a rear frame is pivotally arranged on both sides of the rear end, and a rear wheel group is pivotally arranged at the end of the rear frame, and each rear wheel group is respectively composed of a pivot seat, a rear fork, a rear wheel and a tension spring Each rear fork is pivoted in each pivot seat, each rear wheel is pivoted at the bottom end of each rear fork, and each tension spring is hooked on the hook end of each rear fork, and the free end of each tension spring is respectively fixed on each The under...

AI Technical Summary

Problems solved by technology

[0003] Same as the frog-style human massage car, most of the frog-style human massage cars on the market, because the rear frame is basically parallel to the ground, and each rear wheel group is provided with a tension spring, the user repeatedly unfolds and retracts it. In the process of combined movement, it is necessary to exert a large force on the second rear frame to make it unfold, so as to maintain the original state of motion, which not only consumes a lot of physical strength for the user, but also makes the car body move relatively fast. Slow, when encountering obstacles or slopes, you need to use your feet to land on the ground to give you the thrust to continue moving forward, which seriously affects its entertainment and movement; In the process of repeating the movement of unfolding and collapsing, it is easy to cause uneven elastic force of the two tension springs, which will affect the balance of the car body, making the car body not easy to be controlled by the user, thus affecting its entertainment and sportiness

Furthermore, most of the frog-style human massage cars on the market have complex structures and are not easy to carry and store.
