Description

The kart of assembling preventer

Technical field

This utility model relates to field of motor vehicles of lying fallow, and relates more specifically to kart.Especially, according to Different aspect, this utility model relates to the protection of kart and it is driven and carries out described kart Regulation, the regulation described kart carried out especially in accordance with driver's stature.

Background technology

Different from travelling vehicle on highway, kart is to close (such as passing through of being steered on runway Thermal Motor or electric motor drive) motor vehicles.These runways at outdoor (" outdoor ") or Indoor (" indoor ").

Two kinds of major type of karts can be distinguished: taxi kart and amusement-contest kart.

The first is to be managed by professional, professional kart is leased to individual's (renting bill), Hold the enterprise of personal motivation activity or other.The second is mostly privately owned, by driving and participating in Contest, for private home entertainment.

This utility model can be applicable to all types of kart.But, this utility model is more specifically applied In taxi kart.It is true that these karts are by the most different people of numerous different statures having Drive.Therefore the driver making kart be applicable to different stature it is especially desired to.

For hiring out, the dash speed value of kart is usually 60km/h, and entertain-contest kart Dash speed is more than 120km/h.

Or, either hire out and use or amusement-contest use, often generation is out of hand and runway deviates.Logical Often notice, owing to kart travels in " fleet ", the most travelings (which increasing collision risk), Increase the weight of phenomenon out of hand.

Therefore the collision that kart and its driver stand is multiple: the collision of runway guard rail and two cards Collision between fourth car, these collisions occur in any possible angle.

Obviously it is recognized that collision is probably violent, may not only to cause kart structure and adnexa damage Bad, and be also possible to threaten to the safety of driver.

It is important, therefore, that the acceleration produced with vehicle and driver should be the least.

Saying from technological layer, there are some characteristics relative to other sport vehicle in kart.It is true that they Both axle device without differential was also without suspension arrangement.

Do not set the ability that suspension arrangement causes kart to be turned and depend largely on the deformation on chassis, if deformation Suitably, chassis can promote inside rear wheel or alleviates inside rear wheel burden and therefore avoid understeer.

In other words it is important that in order to enable smooth and easy driving, chassis should have enough motilities.

Meanwhile, when attempting the protection mechanism designing kart and its driver's anticollision, substantially to integrate Multiple kart guard members should ensure that several functions, especially:

-avoid overlapping and embed；

-avoid contacting with other kart wheel；

-anti-the abrasion caused due to contact；

-apparatus with shock absorbing；

-do not lose wheel earth-grasping force；

-high temperature resistant (especially at exhaustor)；

-contribute to attractive in appearance.

For station wagon, it is recognized that strain energy of distortion may result in destructurized, and contrary with station wagon It is that kart requires that deformation is reversible in the biggest scope.

This condition, especially for renting kart, is required, can persistently travel and avoid the most more Change part, and therefore avoid expense.

But, the bigger frame stiffness on frame plane makes it not absorb energy, does not produce relatively your writing Firmly with therefore great acceleration.For this reason, guard member should be the main member regaining energy.

Finally, it is desirable to kart guard member presents the outward appearance with aesthetic feeling originally.

Therefore a kind of half-way house should be found, to meet function listed hereinbefore and kart will not be made overweight.

It addition, kart is generally of two pedals being installed in tread portion, an accelerator pedal and one Individual brake pedal.Each pedal is activated by the foot of driver.

In existing most of karts, tread portion is fixed, and its position (i.e. relative to seat away from Position) it is half-way house, be finally not suitable for most of user.

There is also in kart, pedal is installed on slide assemblies, can be at will closer or far from seat Chair.Pedal thus can have the discrete location assembly of the relative seat such as defined by punch block, perforation Being implemented on the plate body of binding-beam, pedal slides on beam, and the locking being mounted with connection pedal in perforation is convex Ear.

When user is in place in kart, answer the position in adjustable pedal portion, so that position is adapted in use to The size of person's lower limb, and allow a user to defeat on pedal with enough.

This regulation is proved to relatively cumbersome, it usually needs the such as third party of runway operator intervenes, The third party must be utilized as this and be arranged on the stick near pedal to unlock tread portion, and mobile pedal is until suitable For the position of driver's stature, with by pedal manual locking the most in a new location.

This consumes the time, for running on track, should intervene all karts in each period, and And finally produce fund waste.

In some cases, when driver occupies on kart seat, himself can contact adjusting rod, i.e. Make this most convenient.When the user that height is higher continues shorter user, mobile pedal holds relatively Easily, user can promote tread portion with away from seat with foot.Otherwise, on kart, shorter user continues Being proved to more complex during higher user: the most in this case, user should exist with foot or hands On pedal, applying pull strength is to be close to seat, and this is difficult, helps this to be can not without the external world Can realize.

Fig. 2 illustrates the structure hidden of kart, or chassis.The component of guard assembly is assembled on chassis.

Fig. 3 A and 3B illustrates the kart guard assembly according to this utility model the first embodiment.Described anti- Protecting assembly includes:

-front guard member 10, including:

-locating part 11, it is connected to chassis 2；

-on locating part 11 slide flow-disturbing part 12；

-two padded coaming blocks 13, are plugged between locating part 11 and flow-disturbing part 12；

-left side and two lateral guard members 20 on right side, including:

-the right and two front-wheel guard members 21 on the left side；

Two sides of-kart and engine side, right rear wheel and the guard member of left rear wheel 22,

-rear protecting component 30；

The friction belt 40 added on-each component (except flow-disturbing part 12).

As shown in Figure 3A, front-wheel guard member 21 is neutralized by screw 14 and 15 at flow-disturbing part 12 by interlocking It is connected with flow-disturbing part 12.And, each front-wheel guard member 21 is pressed against on the inclined-plane at locating part 11 rear.

This allows compress padded coaming 13 (prestress is to limit resilience) when mounted and stop flow-disturbing part 12 Forwards disengage.

It addition, according to principle of the present utility model, front-wheel guard member is connected to kart by chute 16 On the guard member of side (Fig. 3 B).

The side of the side guard member 22 of kart is also equipped with this sliding connector.

Described chute makes front-wheel guard member relatively lateral guard member along the direction of parallel card fourth axletree line In horizontal plane relative movement.

In the close working clearance, chute union piece in other directions.

Under collision situation, chute 16 is fitted to be arranged on for this in holding part on side guard member 22.

According to described embodiment, flow-disturbing part 12 slides on locating part 11 and is the most directly connected to Chassis 2.Front-wheel guard member 21 is no longer directly connected to chassis, but is connected by lateral guard member To chassis.

In said embodiment, by being furnished with the cushion block of cushion by the right and the lateral guard member on the left side It is connected to chassis, by rear protecting component, lateral guard member or trailing wheel guard member is connected to chassis (therefore trailing wheel guard member is not directly connected to framework).By being furnished with the cushion block of cushion by described rear defence Protect component and be connected to framework.Thus, by means of cushion, guard member is around framework " floating ".Front-wheel is prevented Protecting the glade plane space between component and lateral guard member allows the anterior opposite rear on chassis freely rotatable.

Perform protection assembly do not change chassis rigidity and therefore keep wheel grab ability.

Now by the front guard member 10 explained in the assembly according to real first embodiment of this utility model Work.

In the case of head-on crash in kart axis X, flow-disturbing part 12 slides on locating part 11. Padded coaming 13 is compressed.At the end of travelling, flow-disturbing part 12 is pressed against and is placed in locating part 11 base On block on；Described block stop flow-disturbing part enter driver leg in and be limited in front-wheel guard member On compression (without flexing).

Then, wheel guard member 21 falls back in chute 16, such as on the stroke of 6cm.Pass through wheel The deformation of guard member 21 and by vertically moving of being allowed by lining bar, carries out remaining stroke of flow-disturbing part 12 (such as 4cm).

Collide serious time, as flow-disturbing part 12 by backstop on locating part 11, active force pass through locating part 11 Pass in an uniform manner, on the front-axle beam of framework 2, not be likely to result in the bias of framework elastic distortion.

Notice, on the one hand regaining by the slip on locating part of the flow-disturbing part, and on the other hand by protecting Hold the front-wheel guard member 21 at sliding connector 16 together with lateral guard member, ensure vertically Stability in plane.

In the case of crooked head-on crash, rum point is relatively the same relative to kart journal offset and active force Axis tilts.Under the effect of described active force, flow-disturbing part 12 tends to mobile according to three kinds of motions: compression (phase Be similar to afore-mentioned), shifted laterally and around vertical axis rotate.

Buffering by the pressing in the inclined rear face of locating part of the turning of guard member with relative side The compression of material, obtains torque.By wheel guard member 21 in the inclined rear face of locating part 11 Pressing, obtain lateral force.Due to the described surface tilted so that flow-disturbing part produces on locating part Raw depression, so that buffering material works.

In this motion, by the guiding realized by the vertical section of locating part, flow-disturbing part 12 is at locating part Automatically centering on 11.

The second embodiment schematically shown according to Fig. 4, the front guard member 100 of kart is by following structure Part forms:

-supporting sheet 110；

-buffer stopper 120；

-middle sheet 130；

-anti-embedding sheet 140.

Supporting sheet 110 have be fixed on kart chassis, generally flat canned paragraph 111.Supporting slice Plate 110 also has two deformable segments 112 and 113 of circular arc on the both sides of described canned paragraph 111.

Middle sheet 130 be circular arc, and passes through screw each of two end is connected to supporting slice On the end of plate 110.The end of middle sheet and the end of supporting sheet form the attachment of front side protective component District.There is buffer stopper 120, buffer stopper in the space comprised between supporting sheet 110 and middle sheet 130 It it is such as foam block.

Middle sheet 130 can be coated with anti-embedding sheet 140.With preferably by metal material make Holding sheet with middle sheet by contrast, anti-embedding sheet can be made up of plastic material.Preferably, anti-embedding Enter sheet wider, be embedded into the end of another kart in order to particularly avoid the front of kart in the case of colliding Under dish.

The ingredient laterally protected as kart, front-wheel guard member 151 and 152 is arranged on card fourth The right of car and the left side.Each of described guard member is rigidity, and is fixed by its front end 1511 To the attachment regions of front guard member 100, with stop front guard member 100 and front guard member sheet it Between along any rotation of horizontal axis.

Second end 1512 of these front-wheel guard members is fixed to card fourth at front-wheel rear by sliding connector The chassis of car, before sliding connector allows, edge, guard member 100 relative chassis is basically parallel to kart axis Axial sliding movement, but do not allow to make it rotate greatly relative to chassis.In the range of this utility model, card fourth The axis of car is the axis X shown in Fig. 1.

The single small-gap suture of the most several millimeters of described sliding connector allows the rigidity avoiding chassis guard member to surpass Cross the rigidity on chassis and lose the flexibility needed for kart earth-grasping force.

Alternatively, the described rear end 1512 of front-wheel guard member 151 can be fixed to card by sliding connector The side shield component 160 of fourth car or be fixed to itself be connected with kart chassis any other Zero.

In the case of impinging upon kart front portion, the sheet constituting kart front side protective component is deformed. Due to inertia and the layout of described sheet, the two sheet will not deform the most significantly.Such as exist In the case of bigger frontal impact, middle sheet 130 is mutually close with fixing sheet 110, compresses buffer stopper simultaneously 120.The movement of middle sheet can be more than 10 centimetres.

Due to the layout of guard member with especially fix the shape of deformable segments of sheet, sheet end towards Kart rear portion is moved, and does not contacts with kart front-wheel.This moves and causes front-wheel guard member 151,152 Movement, front-wheel guard member towards rear portion slide.For being positioned at the part of foremost, this of guard member A little movement is carried out in the relatively large distance of about 10 centimetres, and therefore, it is possible to effectively buffering driver and kart holds The shock being subject to.

But, these move and do not result in any damage of kart and be reversible.And, these move The dynamic front portion risk around horizontal axis rotation that do not results in, anterior rotation around horizontal axis may cause more Serious accident, as kart overlaps.It is true that front-wheel guard member 151,152 stops this effectively Rotate.Therefore front guard member 10 has the best vertical to stability.Fig. 5 A and 5B schematically shows Go out the 3rd embodiment of front guard member 1000.

Kart chassis 2 is equipped with shock dynamic energy absorber (or buffer unit or absorption plant), figure 5B illustrates the isometric exploded view of structural elements.

In the described embodiment, in the absorption plant anterior position therefore in chassis 2, with bear outside The front sheet 1100 of the kart guard member that object clashes into matches, and therefore towards direction, the court on chassis 2 Along the vertical direction of axis X rising or on one of side of described sheet (lateral or oblique impact) Retreat.

Owing to flexing or bending control member are movable in predetermined angle scope in terms of rotation or pivot, To tend to align with shock axis, the absorption of front or oblique impact is possible.

Chassis 2 has a lateral support structure being made up of two bodys in front portion, two bodys one of them be It is fixed to chassis remainder (such as by two short pads of the most spaced longitudinal tubular) Lower tube body, and second be to be secured directly the One On The Chassis upper tube body.Lateral support structure is lower and upper There is between body the passage of two axles for two guiding elements 1500, be discussed below respectively.

It is anterior that guard member is installed in kart.Guard member especially includes flow-disturbing part or hood (not Illustrate) and front sheet 1100.Hood has coverage technical parts and/or covering and the function of decoration. Its covering housing can being made up of the plastic material for protection is constituted, and local is arranged to be plugged in transverse bar Between 1200 and front sheet 1100.Front sheet is made up of plastic material, is polyethylene herein.Its lateral sheet material Substantially present the curved profile posteriorly caved in.

Protect sheet 1100 before kart and elastic component 1300 is used for supporting absorbing material, and by it Deformation, it is possible to work, and locally accelerate the strain energy of distortion of absorbent assembly.

Elastic component 1300 rabbets the front protection sheet 1100 at kart by fixed component (such as screw) On.

The volume limited by protection sheet 1100 and elastic component 1300 before kart comprises absorption plant, The present embodiment typically has two absorption plants.Two absorption plants being arranged symmetrically with relative to axis X are used In absorbing collision energy by basic deformation and the most purely elastic, drink non-plastic types, to keep away Exempt from memory effect, even if so that original performance also can be retained after multiple impacts.

To this end, as from Fig. 5 B, the rear surface carrying cross bar 1200 of front sheet 1100, cross bar 1200 Two front ends of the rear surface carrying elastomeric cushion material block 1400 for cylindricality respectively of two ends, slow Rush material block and be longitudinally extended and present the direction being provided with longitudinal compression, be i.e. parallel to axis X, the direction Represent collision course herein.

In the present embodiment, post 1400 is cylinder and tubular, and each post has accommodating axially directed bar Axial passage, axially directed bar is made up of guide main body 1500 herein.The flared end 1510 of each post is true The Anti-dislocation function of device when having protected side collision or rear collision.

Be also known as mourning in silence the elastomer block 1600 of block, or ball-and-socket joint, the cable as modification maybe can be limited in Other connectors all of bending stress on this component, are used for releasing guide main body 1500 opposing rail 1200 Link, be particularly useful for avoiding being pulled out in the case of oblique collision.And, guide main body is (in this enforcement In mode, it is cylindrical bar) 1500 trend towards aliging abreast collision axis (or at least mutually close with it), Collision axis should be front or inclination.Elastomer block 1600 acts on guide main body 1500 and contributes to obtaining Obtain the direction.

Especially useful plastic material implements described guide main body.

On the relevant rear surface of the end that elastomer block 1600 is fixed on bar 1200 by screw, it is used for accommodating The front free end of guide main body 1500, provides a certain degree of gap with free end forward, to avoid There is the risk being pulled out.The rear end of each post 1400 is protected cylindrical covering 1410 and is covered, cylindrical cap Body be drilled with guide main body 1500 axially through hole.

Post 1400 implemented by the elasticity such as with polyurethane or having requirement and other materials all of compression quality.

It is in the length of the substantially corresponding post 1400 of length of guide main body 1500 freely.But it can be set There is surplus (such as by screw scalable), for making post 1400 in the effect being necessarily compressed axially active force Lower by initial prestress, to present the initial strength of the increase resisting compression force under collision situation.

After strong head-on crash, post 1400 is by seriously axial agent pressure, the cylinder form quilt i.e. ceased Deformation, in the present embodiment it is desirable that in generally annular shape.In fact structural material is made in flexing effect Use lower radial deformation.Guide main body 1500 is at the passage being positioned between the body of transversary on chassis 2 Upper longitudinal sliding motion.It should be evident that elastic component 1300 presents two backward channels of main body 1500, again Or the shape that during by facing, top or bottom are distorted presents the channel space being suitable to cincture guiding elements 1500 Shape.

Collision rift, guiding elements 1500 keeps the axially symmetric of each post 1400, i.e. its leading section to keep vertical To ground " faced by " rearward end.Therefore leading section is moved along the exclusive path of the geometrical axis of post 1400, without relatively The lateral distortion of this local axis, except between the initial radial that exists around guide main body 1500 when needed Gap.It is noted that, the material of the post 1400 being compressed axially trends towards radially bending in the way of outwardly and inwardly Song, i.e. trends towards near guide main body 1500 and therefore cancels whole initial diametrical clearance.Can also be the most right In.

When collision, initial in collision, the depression of the middle body of front sheet 1100 cause its end 1110, 1120 forwards pivot, and i.e. pivot to more horizontal bearing of trend.

Notice the enforcement shape (main body 1500 or other) regardless of guiding elements, if front sheet 1100 Crush stroke allow, guiding elements all can be fixed by its front end (as directed piece 1600) or rear end. Therefore guiding elements is fixed by relative chassis 2.

In the embodiment shown, on top view, two guiding elements 1500 limit parallelogram Two longitudinal sides, two transverse sides in parallelogram be above made up of bar 1200 and later by The virtual circuit or the equivalent that connect two passages 210,220 are constituted, and limit the slip of guide main body 1500 Channel rear portion position.The described parallelogram rectangular when assembly is not by any lateral stress, laterally Deformable under collision situation, this is owing to each of its four angles is to pivoting in two respective side Assembling.

It is true that two anterior angles have respective elastomer block 1600, elastomer block has the function of ball-and-socket joint, Ceasing under state, their each ensured two anterior angles elastic is maintained on 90 degree.Main owing to guiding The post 1400 passing guide main body that is spirally connected of body 1500 has slight being compressed axially, the rear end of post, more really Cut ground lid 1410, be pressed against on the purely lateral front surface on chassis 2, so that post 1400 is the most vertical To direction on the most elastic force-applying in guide main body 1500.

Therefore it will be noted that available ball-and-socket joint or equivalent replace anterior angle elastomer block 1600, there is no angle return Elasticity, because on rest position, post 1400 has kept the most longitudinally-aligned by rear end.Described ball-and-socket Joint or equivalent, can simplify as simple combination member, separating, i.e. of the relevant dual-side of prevention rectangle Have no need to ensure that the guiding in terms of mutual rotation of the relevant both sides.

Limiting two relief angles by passage 210,220, this garter spring that passage is formed determines relative to chassis The retrogressing channel position (longitudinal x, horizontal y and height z) of 2, i.e. forbids three along three direction translations Individual degree of freedom.

Therefore the side collision on component 11 will not cause the dismounting of guiding elements, but makes bar relative to longitudinal axis Off center, rectangle above be changed over parallelogram by this meeting, two longitudinal sides of parallelogram (i.e. guiding elements) longitudinal axis relatively tilts.Therefore resistor still works with by returning two guiding structures Part ensures desired buffering.

Such as the angle range of both sides, longitudinal axis direction each respectively can be limited in 15 degree, even 30 degree. In such scope, guide main body slip in respective passage is still guaranteed, although collision is suitable A part of horizontal, corresponding active force presents and accounts for leading axial component, although and on the wall of passage Not not stopping due to fricative stinging, two respective type frame are still can and deposit.

The advantage that described method presents is for having strong absorbability, beyond reference energy: active force increases, but It is to increase in a progressive way, has:

The compression stage of-elastic absorption component；

The compression stage of-control flexing, in this stage, flexing control member retrains in the way of antagonism flexing Elastic absorption component；

-alternatively, the new compression stage of elastic absorption component.

Described method thus the most excellent elasticity is provided, and do not damage, even if after 100 times are collided.

According to this utility model, regardless of driver's stature, kart also has driver oneself can be held The tread portion 60 of relative seat of changing places regulation.

To this end, once tread portion is in the unlocked position, return mechanism trends towards making seat be returned to tread portion 60 Additional.Next is additionally provided with other regulation, especially seat and the regulation of steering column.

Tread portion assembly 60 carries brake pedal 61 and accelerator pedal 62.Described brake pedal 60 is mounted to The central beam 70 being connected with chassis 2 is slided.

By along beam 70 retractable step portion 60, carry out the regulation of tread length, i.e. pedal remote relative to seat 4 From regulation.

Fig. 7 A and 7B represents regulation and the locking length tune being carried out length by offset lengths adjusting means Joint.

Tread portion 60 is made up of the pedestal 63 slided in central beam 70.The pedestal 63 of tread portion is additionally operable to Supporting is for supporting two leg rest portion 64 of driver's heel.Therefore each pedal 61,62 includes that one is put Foot 64 and a upper bar or section, the pressing on bar or section of driver's foot front end.In operation, step on The upper boom manipulation of plate pivots around the axis of leg rest portion 64.Other shapes of pedal, such as full real or with Flat epimere, it is certainly possible to.

One group of hole can be embodied in the top of beam 70, and it limits tread portion relative to seat dispersion position as much Put.By the pin 65 in one of hole being embedded into beam, tread portion 60 is locked on one of these positions.

When the position of expectation regulation tread portion 60, driver's actuation control button 66, control button and pass through Jacket cables 67 is connected to lock pin 65.The actuating of described control button 66 causes jacket cables 67 to bounce back, Lock pin 65 is released from the hole that it is assembled by this.

Described lock pin 65 can arrange striking point so that when kart bears strong hit, and lock pin ruptures, and Therefore its hole assembled it is released to.Thus tread portion 60 is moved back away from seat under the pressure that driver's foot applies After, this can limit the injury caused driver's foot and ankle due to shock.Also can arrange, to being placed Stroke end block on central beam 70 leading portion also arranges this fusing.

According to another kind of method, regulation implemented by available tooth bar, and cable manipulation is convex with what the tooth of tooth bar was meshed Ear.It is also possible for carrying out continuously adjusting, such as with the mechanism of next description type, to regulate steering column.

Spring 68 is connected to the stopper slot 681 that is placed in beam 70 and by another by one of its end End is connected on the stopper slot 682 that is placed in the pedestal 63 of tread portion.When lock pin 65 is released, Spring 68 trend towards making tread portion 60 from its farthest away from position to reduce away from position return.

Once driver's release control button 66, pin 65 drops in the hole of its beam 70 faced toward immediately, So that tread portion automatic locking is in a new location.If driver expects that tread portion is positioned at such as along beam At half stroke, therefore have only to release control button 66 at the half stroke of tread portion: sell dressing Putting in its hole faced toward, therefore tread portion locks on centre position, and spring 68 the most no longer makes to step on Plate portion is closer to seat return.

As modification, spring 68 is replaced in available pneumatic or hydraulic pressure pressurized strut, and pressurized strut can make tread portion To seat return, leniently convict somebody slow tread portion at stroke simultaneously, with the return movement in buffering pedal portion, and keep away completely Exempt from the most mobile.

Beam 70 relative level tilts, or more properly, the planar tilt relatively limited by chassis 2, and to Kart front promotes.So, when tread portion is away from seat, between leg rest portion 64 and kart base plate Space increase, it is assumed that be the base plate of level, be i.e. parallel to chassis plane.Below with reference to Fig. 8 A and 8B Described inclined floor is described.

And, the position on step height be also adaptable for driver's height (in view of foot size substantially with drive The person's of sailing height is proportional), driver sits in can be on the position of comfortable driving, and its heel is placed in the end simultaneously On plate.

Therefore, for driver, tread portion is adjusted remote relative to seat, to be suitable for the size of its lower limb, so Rear driver sits in kart, is the most comfortable.It is true that driver can sit on steering position, And press the control button 66 of the sphere of action (such as, near the pedestal of steering column) being positioned at hands.Then By means of return mechanism 68, tread portion is automatically close to seat.When tread portion is positioned on desired locations, only Need driver's release control button 66, so that tread portion automatic locking again.If tread portion exceedes Desired locations, tread portion can be shifted onto on its position selected by driver simply with foot.

It addition, control sheath by brake pipe and acceleration, brake pedal 61 and accelerator pedal 62 is caused to move Control be sent to kart controlling organization.

Fig. 8 A and 8B illustrates the steering module of kart, wherein, is especially equipped with turning of kart steering wheel Xiang Zhu and tread portion 60.In fig. 8 a, the left side of module to being set to towards kart front, right side court Rearward.Demonstrate two tilting sections 80, the kart base plate below tilting section correspondence pedal in the accompanying drawings. It is included in such as 5 ° and 30 ° by being formed with the horizontal plane being parallel to kart axis X (again or parallel ground) Between an angle [alpha], described base plate slopes slightly downward towards the direction in kart front.

This configuration can ergonomically regulate pedal: when tread portion 60 is moved to kart front Time, the space between leg rest portion 64 and base plate increases.Leg rest portion 64 can be positioned, so that no matter driving Member's stature how, and leg rest portion can be in a half height of heel.

When driver takes a seat on the seat, the position of a half height of heel is preferable position, and both legs are curved Bent and heel is placed on, and toe end is pressed against on pedal." naturally " position of this position correspondence foot, I.e. on this position, it is not necessary to or by stretching or tightening up ankle muscle by bending.

For the position of whole tread portion, these components can obtain foot that is that optimize and that be suitable for driver's stature Position, portion.So can make all drivers that leg rest portion is maintained at heel one half height, pedal is kept In big toe position, and the angle of foot opposite leg will not force driver's muscle contraction.
