Description

But the single wheel cycle that bending folds

Technical field

The utility model belongs to the technical field of single wheel cycle, it is mainly by be provided with a Folding structure between the single-wheel vehicle frame of single wheel cycle and standpipe, see through the special pearl design of this Folding structure, allow standpipe single-wheel vehicle frame bending or combination relatively, to solve existing single wheel cycle because of can't folding, and cause storage or the excessive problem of transport space, and can promote the alerting ability of single wheel cycle space utilization, effectively promote its economic value.

Background technology

Single wheel cycle is a kind of sports equipment that is used for the balance training sense, it is used in various stunt and the training place widely, and existing single wheel cycle mainly is to be provided with a wheel body at a single-wheel vehicle frame lower ending pivot, and utilize central siphon to be pivoted with a crank group on single-wheel vehicle frame top, this crank group can see through chain and drive wheel body, and the single-wheel vehicle frame also is connected with standpipe at the central siphon upper limb, riser top ends can be for plugging seat cushion, the user can be sitting in trample the crank group on the seat cushion, with the driving single wheel cycle, and training individual's degree of balance;

And existing single wheel cycle has two kinds, and one is shorter and smaller low dwarf forms single wheel cycle, and another then is the taller and bigger type that grows tall single wheel cycle; These single wheel cycles are because it has unique function mode, therefore such design there is no too big problem, but it has many problems really in storage and transportation, with the wherein taller and bigger type that grows tall single wheel cycle is example, therefore because its height even reach more than 1.5 meters no matter be in transportation or storage, all needs to take bigger space, and can cause unnecessary waste, even have influence on the flexibility ratio of storage and transport space utilization.

Via above-mentioned explanation as can be known, the Skidproof structure ubiquity of traditional single wheel cycle has can't folding and problem such as the space utilization is dumb, and has influence on the convenience that uses the single wheel cycle utilization, and historical facts or anecdotes is necessary to do further improvement.

Summary of the invention

Therefore, the design people deeply inquires at the problem that existing single wheel cycle is faced when preserving with transportation, and actively seek the scheme that solves, research and development through long-term endeavour, but success finally develop a kind of simple in structure and single wheel cycle that bending that can amount to rapidly folds, so that what user transportation and storage, thereby promote the whole convenience that uses.

The utility model is reached the single wheel cycle of above-mentioned purpose and usefulness, mainly come specific implementation by following technological means: it mainly is made up of the single-wheel vehicle frame that a bottom is pivoted with wheel body, single-wheel vehicle frame top is provided with one and supplies group to establish the horizontal central siphon of crank group, the central siphon periphery is provided with the protruding pipe of a upwardly extending vehicle frame again, the protruding pipe of this vehicle frame top is connected with one for the standpipe of inserting the seat cushion of pulling, and is provided with Folding structure between protruding pipe of vehicle frame and standpipe;

This Folding structure mainly also is installed with the following disk body that a section is the ㄩ font on the protruding pipe of vehicle frame top, the bottom of the protruding pipe of the corresponding vehicle frame of Folding structure what standpipe is installed with the last disk body that a section is the ㄇ font again, wherein go up the disk body one side periphery cooresponding periphery of disk body under the what that is pivoted, again, the side periphery in addition that the different what of following disk body articulates is pivoted with an axostylus axostyle, axostylus axostyle central authorities are formed with a perforation that runs through, and perforation can be established a pull bar that is coated with lining and elastic component for lock, and this pull bar top forms the pivot head in big footpath;

Moreover the pivot head on pull bar top is pivoted with a tommy bar, and tommy bar is formed with side grain at root edge, and wherein side grain can be against location what lining end face;

Thus, the user can utilize and control tommy bar standpipe and single-wheel vehicle frame can be decomposed or make up, and allows single wheel cycle can dwindle its height after bending, to be user-friendly for transportation or storage, promotes empty flexibility ratio of asking utilization.
