Versatile combined rowing and swinging bicycle

Abstract

The invention discloses a versatile combined rowing and swinging bicycle, which is characterized in that: an inner sleeve at the front end of a beam [1] is inserted and locked with a C-shaped outer sleeve with a seat slide way at the rear end of the beam [1], the top end of the inner sleeve of the beam [1] is connected with a front fork [4] via a shaft, pedal devices [11] are installed at the both ends of the cross beam of the front fork [4], the lower end of the front fork [4] inclines inwards and extends to be connected with the front axles of two wheels, the C-shaped outer sleeve of the beam [1] is inserted and locked with a shaft on the top of a beam column [2], and a slide seat [9] is installed on the slide way of the beam [1] to compose a combined swinging bicycle. The combined swinging bicycle becomes a road snow stick swinging bicycle in case that a double-rod road snow stick with a rubber head is used, becomes a road single-paddle swinging bicycle in case that a double-blade road single paddle with a rubber head is used, and becomes a versatile combined rowing and swinging bicycle in case that a versatile double-rod D-shaped chain disc rowing device is used; and the combined swinging bicycle may become a unique and novel foot-controlled electric swinging bicycle or rowing and swinging bicycle by adding a motor device. The bicycle is easy to detach and combine, as well as is an ideal instrument for the sports events, exercise and rehabilitation of people.

Description

Technical field: [0001] The invention relates to a four-wheel bicycle device, in particular to a multi-combined rowing and swinging bicycle. Background technique: [0002] At present, the ZL200610091907 patent has used the double-beam parallel shaft connection structure to solve the problem of stable steering and the use of C-shaped double-groove chain discs to solve the problem of advancing both the push and pull bars. However, it has a large volume and a large turning range, a long chain does not correspond to the flywheel, it is easy to drop the chain, it is inconvenient to disassemble, store and transport, the production process is complicated, and the function of the car is single. Invention content: [0003] The present invention is a research aimed at the above-mentioned problems: the invention is positioned on the combination of multiple functions and multiple styles. First of all, in the experiment, it is found that if the lower end of the front fork [4] of the c...
