Description

Mini-scooter

The present invention relates to a kind of Mini-scooter by claim 1 preamble.

In two-wheel car invention beginning since the 19th-century particularly decades ago, coaster is just known.It is more comfortable than walking or running to travel with coaster, because driver's deadweight is supported by coaster.Only need apply proal power with leg.This can do such comparison, and promptly the object of 50 kilogram weights is that thick stick transports piggyback or with hand barrow.

Travel to be different from principle with coaster and use bicycle running.Must apply bigger power with leg all the time on bicycle, this power makes the bicycle persistent movement, and vehicle also must be all the time in motion.If do not move, just can not keep balance again.On coaster, keep balance with leg.Static, motion and speed are determined by the driver, and are met its wish.Make a move on the coaster by operating at of coaster and can reach three times of when running a step-length degree.At this moment the driver is as the sensation that " wafing to there " arranged.Coaster can also give non athlete and weakling the experience with new set forward.

It is fast with the paces defined of its promotion actuating device as the driver that forward movement can only reach.This also is the reason why exploitation in 1867 is used for the pedal driving device of two-wheel car and is equipped with change-speed box afterwards, and recovery has rapidly been experienced in the development of bicycle in nearest 15 years as everyone knows.Can provide lightweight today, be equipped with shock absorption device with the perfect hightech bicycle of technology.But they are not suitable for non athlete, old man or disabled person.

Coaster is being made well-known at that time heaviness and form slowly 19th century.It must verify oneself on rugged highway and road.Therefore it has bigger wooden wheel.Therefore common at that time coaster seems heavy.Have only by employing to make pin needn't contact with ground again be contained in the pedal on the front-wheel and can adopt big wheel therefrom, its speed is compared with coaster and could be improved greatly.

The coaster of ordinary bicycle size can not be look to contending with the bicycle that has pedal driving device and change-speed box.However be not suitable for more comfortable and forward movement easily with the two-wheel car of driver element.Compare it with automobile and have less wheel, people's aptitude is in welcome again double block (Trottinette) now.The main in the past forward movement instrument as children, it is as hospital and the comfortable forward movement instrument of adrm now.They are equipped with low pressure tire mostly, and it makes can make comfortable and noiseless forward movement.

Recently they are more welcome than " Fun " car.Collapsible and the light design plan of structure is found everywhere them.These vehicles with development prospect all have little wheel.The great advantage of this vehicle is in light weight.Be not suitable for using the double block forward movement as highway or pavement surface, people just accept them, and walking again allows to travel until the road surface again.No matter be that the tempting mode of forward movement or people's interest are unusual a bit and have development prospect, and demonstrate its feature of environmental protection, nearly this double block of a period of time was once widely popular.

This double block has big shortcoming, and promptly they can only be used by people full of physical strength and that can also run to a certain extent except normal walking.That is to say that they are not suitable for the elderly and do not have the people of sportsman's physique.

The objective of the invention is now, make a kind of simple as far as possible, deadweight less than 4kg, by the least possible part roadster that form, modern lightweight construction.It should be placed in the car trunk.Should folding easily without instrument of Foldable type by Mini-scooter of the present invention, and be placed in chest or the knapsack.It should not noticeable and not carry with paying dues in daily round traffic.

This on the other hand coaster should have the failure-free rideability.Air-inflation tyre and big ground clearance should be provided.Even on wet highway, also must guarantee well but not stuck braking.

Mini-scooter with claim 1 feature has been realized this purpose.Other features of the present invention are obtained by dependent claims, and its advantage is explained in the following description.

The preferred embodiment that these diagrammatic representations illustrate with following elaboration.

As shown in Figure 1, Mini-scooter 1 is to the maximum wheel 3 and 4, a preposition deflector 8 and the seat cushion 6 of 200mm by a framework 21-24, two diameters.Framework 21-24 is made up of four bulk-breakings: undercarriage pipe 24, put on the shelf pipe 23, steering head pipe 22 and bench hassock tube 21.Frame unit 21,22,23 with 24 all to be connected all be captive joint.

Bench hassock tube 21-is at travel direction-be provided with perpendicular to road surface 30.It is with 45 bending backward in the bottom.The end of bench hassock tube 21 sweeps of the wheel carriage 26 of trailing wheel is welded on the fork-shaped beam.

Cushion rack 5 inserts in the bench hassock tube 21.The external diameter of cushion rack 5 is equivalent to the internal diameter of bench hassock tube 21, make the sealed ground of cushion rack 5 shapes but can along bench hassock tube 21 and cushion rack 5 common axis line longitudinal movements fix.This movement of cushion rack 5 in bench hassock tube 21 suppresses by a fixing device 14.This fixing device 14 is a kind of devices that are used for this purpose that can buy on market.The internal diameter of bench hassock tube 21 can reduce by clamping on certain-length, and cushion rack 5 is securely fixed in the bench hassock tube.Usually select for use and can unclamp reliably and clamp and however still can guarantee reliably fixing fixing device 14 with suitable power.Seat cushion face 11 must be provided with road surface 30 all the time abreast at travel direction.

In order to use the correct function and the advantage of Mini-scooter 1, the height of seat cushion 6 should be adjusted to user's crotch height exactly.The driver adjusts bench height like this: make when he stands on the ground with footwear and/or both feet, feel seat cushion 6 slightly in crotch.The rearmost point p of seat cushion 6 does not allow to exceed the plumb bob vertical v of trailing wheel 4 axis 17 tops.

Bench hassock tube 21 near with lower transverse tubule 24 junctions below 45 ° of bendings backward.The line of centers of bench hassock tube 21 must be at least 100mm to the horizontal throw of the plumb bob vertical v of trailing wheel 4 axis 17 tops.Bench hassock tube 21 part of bending backward stretches out by this way backward, make its plumb bob vertical v on forming from bench hassock tube 21 centers to axis 17 with carriage 26 apart from x.

For the structure of this Mini-scooter 1, the bench hassock tube that has fork-shaped beam and rear wheel bracket 21 of 45 ° of bendings plays the elastic cantilever beam action backward, and it brings the soft sensation of travelling for the coaster driver by its elasticity.

For weight and the cost that makes Mini-scooter keeps low as far as possible, the characteristics of some configuration aspects have been adopted.Two fork-shaped carriages 25 that for example are used for front and back wheel 3,4 are being the same with 26 aspect size and the processing.Two extruding roller drgs (Walkrollenbremse) 12 are fixed on the fork-shaped carriage 25,26 in a corresponding way, and they also are identical in making with the size aspect originally.If it manufactures and has fixingly, that is collapsible frame not is just Mini-scooter 1 has minimum part so.This structure just only is made up of about 95 single parts, and the some of them part is identical with 26 with the part that pushes the roller drg as wheel 3 and 4, fork-shaped carriage 25, also needs about 16 other parts for folding structure.This normalisation of part greatly reduces manufacturing cost.As a comparison: the common wire wheel of bicycle is made up of about 90 parts.

For Mini-scooter 1 is designed so that it is collapsible, so that be placed on baggage container or the train luggage rack, upper frame tube 23 and lower frame tube 24 on axis a (Fig. 1), be equipped with respectively a double-strand chain 2,2 ' and voluntary insurance with strengthen double-strand chain 2,2 ' mobile cover 42 (Fig. 6).In Fig. 2 and 3, schematically illustrate folding possibility.

Double-strand chain 2 and 2 ' should be stablized and

connection box pipe

23 and 24 reliably.Hinge connecting link 36 has a linear side that distributes with respect to the line of centers wedge shape of bolt hole 35 in a side.Bolt hole 35 ' from the distance of straight line v (Fig. 6) less than bolt hole 35 " apart from w.But two bolts hole 35 ' and 35 " the line of centers that is connected accurately be parallel to lower frame tube 24 or upper frame tube 23 line of centerss.The wedge track 38 that moves cover 42 as shown in Figure 6, m is designed to wedge shape with respect to line of centers.

By moving pushing of cover 42, be enclosed within equally on the outside face with respect to the hinge connecting link 36 of line of centers m tilt distribution with respect to the wedge track 38 that distributes in the inclined on the line of centers m.The absolute zero-lash self-locking that reaches double-strand chain 2 by this wedge embedding connects.

At folded state, two wheels 3 and 4 roughly placed side by side overlappingly, preceding half-sum is later half to be designed to equally longly, that is the center that line a is arranged between wheel shaft 16 and 17 is favourable.Deflector 10 is placed on seat cushion 6 sides, and this obtains the maximum width 14cm of folding Mini-scooter simultaneously.

Seat cushion 6 is captiveed joint with bench hassock tube 5.For with Mini-scooter 1 comfortable travelling importantly, seat cushion surface 11 follows sails direction f and is parallel to road surface 30 and is provided with.Seat cushion 6 stretches out backward and at most only allows till the direction plumb bob vertical v on the axis 17 (some p).

Preposition deflector 8 is made up of steering tube 9 and lead arm 10.These two parts cast in together or weld, and are formed as one unit preposition deflector 8.Preposition deflector 8 rotatably is connected with deflecting bar 7.Steering tube 9 is with respect to the line of centers level of deflecting bar 7, vertical and symmetrical.The line of centers of steering tube 9 is represented steering shaft 7 AnchorPoints from Fig. 5 some q equals 23mm and is offset forward with the size z that protracts.

Deflecting bar 7 is captiveed joint with control tube 27 by means of clamping folder 14.In order to adjust the height of deflector 10, it unclamps by an eccentric rod, that is unclamps without instrument, and deflecting bar 7 moves in control tube 27 by this way, that is, roughly the height with seat cushion 6 is identical to make it.The corresponding mode of cushion rack 5 usefulness clamps folder 14 with one and is fixed in the bench hassock tube 21.This clamps folder and also is clamped together with eccentric rod, and the height adjustment range of deflector and seat cushion is 300mm.This big setting range makes the Mini-scooter both can be by the children more than 7 years old, and also man that can still be retained youth up to 70 years old and woman use.People can not travelled by or not other vehicle injury ground on the footway with Mini-scooter.

For Mini-scooter being leaned on the wall with can saving the position or when folding, only needing as far as possible little position, preposition deflector 8 can be rotated 90 ° to both sides by pulling up from normal horizontal position arbitrarily, and it automatically snaps in for the necessary horizontal position of travelling with a device that is provided with for this reason.

Front-wheel 3 can be rotated to support on the axle 16.Axle 16 is captiveed joint with the fork-shaped carriage, and the fork-shaped carriage passes through the fork-shaped crossbeam captives joint with control tube 27.Control tube 27 supports and is fixed in the steering head pipe 22 by the bearing of axial and radially-directed.

Trailing wheel 4 can be rotated to support on the axle 17.This is captiveed joint with the bench hassock tube 21 of bending backward by the fork-shaped crossbeam with fork-shaped carriage 26.

On trailing wheel 4 and front-wheel 3, establish an extruding roller drg 12 respectively.They are designed to foot-operated brake.The center of gyration of the foot brake pedal 12 of extruding roller is exactly the center 29 of fork-shaped crossbeam before and after being used for.Preceding extruding roller drg 12 is equipped with a splash board 40.The function of extruding roller drg 12 has detailed description in Swiss Patent application 2,000 0767/00.Splash board 40 is simple plastic dam of known type.
