Embodiment Construction

[0016] see Figure 1~2 As shown, the roller 2 includes a tire 1 arranged outside the roller 2, a support spoke 3 arranged in the roller 2, a horizontal center shaft 8 arranged at the center of the spoke 3, and a center bearing 9 enclosed within the horizontal center shaft 8. The spoke 3 is the spoke of the roller. It is different from the bicycle spoke in that each spoke is bent at a certain angle in a section, and can also be arc transitioned. The radial spokes are gathered in the middle of the central axis 8 and fastened, such as figure 2 As shown, the left and right spokes protrude in opposite directions to form a drum-shaped structure with symmetrical upper and lower conical cavity surfaces and parallel left and right planes. This structure can not only increase the volume between the two spokes, but also increase the elasticity. figure 1 The middle of the spokes shown is only crossed, and the middle of each spoke is added with a figure-eight cross, which is convenient fo...

Abstract

The invention discloses a large-roller recreational vehicle which comprises a roller. A U-shaped seat frame is arranged in a spoke; a pedal transmission chain component, a pedal transmission chain, a spoke transmission chain component and a connection transmission rod are arranged below the seat frame; and a steering control component, a brake component and left and right balance pulleys outside the spoke are arranged above the seat frame. The seat is placed in a space surrounded by the large roller and the spoke, the pedal transmission chain component is arranged below the seat frame, thus the center of gravity is remarkably lowered, the stability is improved, and the elastic spoke and the left and right balance pulleys prevent the turnover and falling injury of a wheelbarrow. The large-roller recreational vehicle disclosed by the invention is a novel bodybuilding, recreation and instead-of-walk toy, has the characteristics of low center of gravity and stable running as well as effects of creating novelty and stimulation, and is particularly suitable for the physical fitness exercises in the teenage entertainment places.

Description

technical field [0001] The invention relates to a bicycle, in particular to a bicycle recreational vehicle with pedal rollers. Background technique [0002] As a means of transportation, two-wheeled bicycles have had a glorious history of development in my country, and now they are recommended as a light, energy-saving, environmentally friendly, and flexible means of transportation. The unicycle is not as lucky as the two-wheel bicycle. It is only used as an actor's prop in acrobatic performances, that is, only specially trained acrobats can show the charm of the unicycle. When the ground seat moves at the highest point of the wheel, the center of gravity increases, which is difficult for ordinary people to control. In order to solve the problems of safety and speed of the unicycle, people have made various improvements to the unicycle, such as CN20081028539, CN200810028888, which propose a fast unicycle. The two sets of chains and transmission wheels solve the problem of s...
