Description

Wheel scooter before many

Technical field

The present invention relates to toy for children technical field, especially relate to a kind of many front wheel scooters.

Background technology

Kickboard Scooter is the novel product form of the another skateboarding after conventional skateboard.User utilizes Kickboard Scooter can do various fancy transition activities, coordinates waist torsional movement, can reach significant slimming effect, also can strengthen the balanced capacity of individual.So Kickboard Scooter is once appearance and the fashionable whole world.

Frog scooter is the one in Kickboard Scooter, is also breast-stroke car, frog car, Breaststroke Sports Car.It uses the principle that horizontally slips, and utilizes both legs outward thrust and inside associated form to produce thrust, naturally can move to few movable sartorius at ordinary times.Frog scooter propulsive effort is mainly derived from two trailing wheels, these two trailing wheels are Universal wheel structure, and during motion, user's bipod stands on two pedals respectively, and two legs repeat to do one and open a resultant motion, two trailing wheels alternately present " interior eight ", " outer eight " shape, and propelling thrust just produces thus.

Along with the progress of technology, in order to meet the needs using Kickboard Scooter compared with small children, the front-wheel of common Kickboard Scooter especially frog scooter is set to multiple by the producer, makes Kickboard Scooter operationally safer.But, after so improving, often cause the rising of the complex structure of Kickboard Scooter, cost, alerting ability reduction.

Summary of the invention

For the deficiency that above-mentioned prior art exists, the object of this invention is to provide a kind of many front wheel scooters, it has, and structure is simple, cost is lower and firm, and alerting ability is better, the better feature of stationarity.

To achieve these goals, the technical solution adopted in the present invention is: wheel scooter before many, comprise body frame, body frame front portion is articulated with grab rail, rear portion is articulated with after-frame for this, grab rail upper end is provided with handrail, lower end is provided with front-wheel for this, this after-frame is provided with pedal, rear end is provided with trailing wheel, and the lower end of described body frame is fixed with one and falls " U " font or the jaw of " V " font of falling, and this front-wheel is 2 of 2 ends being arranged at this jaw respectively.

Described 2 front-wheels are individually fixed in the two ends of a cross bar, and two ends of this jaw are equipped with mating holes, and this cross bar is through these 2 mating holess.

It is the connection pipe that vertical sleeve pipe and front end are fixed on the trailing flank of this sleeve pipe that described body frame comprises one, and this grab rail is through this sleeve pipe, and the front end of after-frame is connected to the rearward end of this connection pipe.

Described grab rail comprises the bottom tube being fixed on this jaw top and the upper pipe being connected to this bottom tube top, and this bottom tube is through in this sleeve pipe.

The spacing L of two ends of described jaw is: 250mm≤L≤450mm.

The present invention is compared to the prior art advantageously: structure is simple, cost is lower and firm, and alerting ability is better, stationarity is better.Many front wheel scooters of the present invention, by 2 front-wheels being arranged at the bottom of jaw, ensure that Kickboard Scooter stability in use, safer.And for the parts reaching foregoing advantages used are less, comparatively simply, cost increase is less.Meanwhile, the layout of front-wheel is comparatively reasonable, and the spacing of 2 front-wheels is comparatively reasonable, makes the operation of this Kickboard Scooter comparatively flexible and steady.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, the present invention is further described:

Fig. 1 is the schematic perspective view (not shown handrail) with the how front wheel scooter of an after-frame of embodiments of the invention;

Fig. 2 is the schematic perspective view with the how front wheel scooter of two after-frames of embodiments of the invention;

The front view (semi-sictional view) that Fig. 3 is jaw of the present invention, front-wheel coordinates.

Detailed description of the invention

Embodiment, is shown in shown in Fig. 1 to Fig. 3: wheel scooter before many, comprises body frame 10.This body frame 10 front portion is articulated with grab rail 20, rear portion is articulated with after-frame 30.This grab rail 20 upper end is provided with handrail 40, and this handrail 40 is generally 2 that point to occupy these grab rail 20 both sides.The lower end of this grab rail 20 is provided with front-wheel 50.This after-frame 30 is provided with pedal 60, rear end is provided with trailing wheel 70.As common Kickboard Scooter, the support body of this after-frame 30 for extending back, this pedal 60 for being fixed on the tabular body on this support body 30, this trailing wheel 70 for be arranged at 1 of this after-frame 30 rear end or be arranged side by side multiple.As frog scooter, the rear portion of this body frame 10 is articulated with 2 after-frames all extended back 30, and the middle part of these 2 after-frames 30 is equipped with a pedal 60, rear end is equipped with a trailing wheel 70, and this trailing wheel 70 is generally cardan wheel.

Further say, the lower end of this body frame 10 is fixed with one and falls " U " font or the jaw 23 of " V " font of falling, and this front-wheel 50 is 2 of 2 ends being arranged at this jaw 23 respectively.Like this, by less parts, ensure that stability when this Kickboard Scooter runs, and the layout of 2 front-wheels 50 is comparatively reasonable, the alerting ability that Kickboard Scooter runs can not be reduced because wheel increases.

Continue to optimize:

These 2 front-wheels 50 are individually fixed in the two ends of a cross bar 51, and two ends of this jaw 23 are equipped with mating holes 231, this cross bar 51 free-running fit through these 2 mating holess 231.Such mounting means is comparatively simple.

It is the connection pipe 12 that vertical sleeve pipe 11 and front end are fixed on the trailing flank of this sleeve pipe 11 that this body frame 10 comprises one.This connection pipe 12 is low skewed in, rear end high in front end usually.That is this sleeve pipe 11 and this connection pipe 12 are in " people " font.This grab rail 20 is through this sleeve pipe 11, and the front end of this 1 or 2 after-frame 30 is connected to the rearward end of this connection pipe 12.Like this, not only reduce the preparation difficulty of this body frame 10, and make the stability of this body frame 10 better.Certainly, usually also bearing is provided with in this sleeve pipe 11.

This grab rail 20 comprises the bottom tube 21 being fixed on this jaw 23 top and the upper pipe 22 being connected to this bottom tube 21 top, and this bottom tube 21 is through in this sleeve pipe 11.That is, this grab rail 20 is split-type structural.Like this, the assembling of this grab rail 20 and this sleeve pipe 11 is convenient to.

The spacing L of two ends of this jaw 23 is: 250mm≤L≤450mm.In the present embodiment, this spacing L refers to the distance between the lateral surface of two ends of this jaw 23.Like this, guarantee that the spacing of 2 front-wheels 50 is at least 250mm, thus make the operation of this scooter more steady.

The foregoing is only the preferred embodiments of the present invention; not thereby the scope of the claims of the present invention is limited; every utilize specification sheets of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
