Abstract
An inclining and steering System made of a usual main fork lying and welded on top on the vertical motion plane frame under the handle-bar (M) and made of the inclining parallelogram System crosswise swinging between the 2 legs of the fork having its 2 horizontal axes (X) grafted to their 2 dual-joint internally anchorating on each leg of the same fork and made of 2 further usual forks externally anchorating on each side of the inclining parallelogram System supporting the 2 usual forks wheels (F, R), this entire System is now able to steer, by driving leverage (E) from the handle-bar (M) and simultaneously to incline the entire vehicle.
Description
TITLE
Inclining and steering System to obtain the Tricycle (with 2 front wheels) or also the Quadricycle (with other, only inclinable, 2 back wheels) to guide better.
DESCRIPTION The Inclining steering System(see i/2=Rg :1,2,3 and2/2=Hg :1,2) includes: a main forkSyst(A), wich hangs on the inclining parallelogramSyst(D), that holds up one on each side the 2 further forks(F+R) welded to the 2 steering axesSyst(X) with their 2 front-wheels. The entire System is able to steer, by driving leverage from the (M)handle-bar and simultaneously to incline. Protagonists of the inclinability/steerability are the: (M)handle-bar(by various leverages) and forkSys(A)anchored to (B)frame. Inclining parallelogramSys(D) that supports sidely the 2 steerable axlesSyst('C) and the 2 front forks-wheels(F&R). The inclining and steeringSystem (see i/2=Rg :1,2,3 and 2/2=Fig :1,2) is an innovation permitting to build a tricycle and a quadricycle (first with 3, then with 4 wheels on the ground, but the 2 back wheels must be only inclining). These vehicles stand up, incline and steer like a bicyde.but in various mode.they are steadily and safely. The new project of the bicycle, using this inclining and steering System, realizes the tricycle(2 front wheels) or quadricycle(2 front wheels and 2 back wheels),wich are stadier and safer vehicles. Both the System(A+D+X)and the System(P+D+X)(i/2=Fig:i,2,3 and2/2=Fig:i,2) include in Front : the main forkSyst(A)+the inclining parallelogramSyst(D) with its 2 axes- Syst(X) grafted to their 2dual-joint(Z)+the 2 steering axlesSyst('C), externally anchored to incli- njng parallelogramSyst(D), are attached into the2 forks/wheelsSyst(F+R).The (M)handle-bar on
Top, by various driving leveragesSyst(E), controls the steering, the inclining and braking in both (triV.quadri)cycles. The main forkSyst(A), welded on top of the frameSyst(B) with its 2 narrow legs lying in the vertical motion plane, having or not inside the 2 shock-absorbers, supports the inclining parallelogramSyst(D) and its 2 axesSyst(X) grafted into 2.dual-joint(Z). Both the Syst("A"+"D"+"X") and the Syst("P"+"D"+"X"), only for the quadricycle, includes
"Rear": the"second"main forkSyst("A"), wich hangs on the"second"inclining parallelogram-
Syst("D")with its 2 other axesSyst("X")grafted into other 2.dual-joint("Z")+the 2 not-steering axlesSystf'C"), externally anchored at the same inclining parallelogramSyst("D"), wich are attached into the 2 forks/wheelsSyst("F"+"R"). The 2 not-steering axlesSyst("C") attached into the 2 forks/wheelsSyst("F"+"R") incline obeying to (M)hand-bar. The"second"main fork-
Syst("A")(with or without the 2 shock-absorbers on its 2 legs), likely the main forkSyst(A), supports the inclining parallelogramSystf'D") by its 2 orizzontal axesSyst("X")grafted into the 2 dual-joint("Z") lying on the vertical motion plane, hinging(Y) them at the 2 forkSyst("A")legs. The forkSyst("A") is welded-on the back of the frameSyst(B). The protagonist of the left/right inclinations, by the (M)handle-bar / frameSyst(B), is the inclining parallelogramSystfD") and its 2 axesSyst("X")with the 2.dual-joint("Z"). The inclining parallelogramSyst("D") has 4 articulated sides, hinged(Y)toghether, to obtain the inclinabilrty. The inclining parallelogramSystfD") and its 2 axesSyst("X")with 2.dual-joint("Z") places between the 2 narrow legs of the main fork- Syst("A"). The 2 not-steering axelsSyst("C"),attached into the 2 forks/wheelsSyst("F"+"R") are mounted on the 2 opposite sides of the inclining parallelogramSyst("D").
In conclusion : in Front of the vehicles the 2 forks/wheelsSyst(F+R) must risult : .1) parallel toward the motion direction, equidistant from the (M)handle-bar axle .2) steerable through the driving (M)handle-bar leveragesSyst(E) toward the2 forks/wheelsSyst(F+R) .3) inclinable simultaneously for the driving (M)handle-bar leveragesSyst(E) action .4) absorbable only in case of the 2 forward shock-absorbers existence In conclusion, "Rear'Of the vehicles the 2 forks/wheelsSyst("F"+"R") must risult :

Claims
1st- The first claim consists of a typical realization by precise sequences of pairing and assemblings(i/2=Fig :ia/3a and 2/2 Rg :iand 2) and by precise sequences of pairing and its sub- assemblings, like to the following points from A to C : .- A- The main forkSyst(A) (having or not 2 telescopic shock-absorbers inside the 2 legs ) is welded centrally on top of the frameSyst(B) with its 2 legs lying in the vertical motion plane. .- B - The 'right and left' inclining parallelogramSyst(D), is crosswise mounted respect to its main forkSyst(A) and it's inside and made of 4 articulated sides(very large the top & bottom) hinging(Y) to obtain the inclinability. This inclining parallelogramSyst(D), with its 2 axesSyst(X)o lying in the vertical motion plane wich are welded on the middle of the 2(larger top & botton) horizontal basis, the 2 axesSyst(X)having,at their ends,the2.dual-joint(Z), so the inclining paral- lelogramSyst(D) placed between the narrow 2 legs of the main forkSyst(A), uses those 2.dual-joint(Z) fixed internally on the 2 legs. .- C - The 2 forks/wheelsSyst(F+R)with their 2 steering axlesSyst('C) up to the driving 5 (M)handle-bar with the leveragesSyst(E),can steer and incline.either on the 'tri' or on the
'quadri'cycle also toghether to the usual breaking leverage actions; these 2 forks/wheelsSyst- (F+R) are both placed to the vertical opposite sides hinged(Y) to the incliningparallelogramSyst(D).
In conclusion - This "first claim'On the System must result the2 forks/wheelsSyst(F+R) for both the System(A+D+X) and the System(P+D+X) so that : O .a) parallel toward the motion direction, equidistant from the (M)handle-bar axel.
Nθte:ForkSyst(A), is built with its 2 narrow legs; outward of inclining parallelogramSyst(D)
Nθtθ:ForkSyst(P), is built with its 2 very narrow legs; inward of inclining parallelogramSyst(D) NotβThe back System("A"+"D"+"X") is like the front System(A+D+X),having behind the only inclinig 2 wheels.having or not the 2 telescopic shock-absorbers inside of the 2 narrow5 forkSyst("A")legs. This back System("A"+"D"+"X") is used to have a quadricycle.
.b) steerable through the driving (M)handle-bar leveragesSyst(E) toward the2 forks/wheelsSyst(F+R). .c) inclinable simultaneously by the driving handle-bar(M) and the leveragesSyst(E) actions, .d) absorbable only in case of the 2 forward shock-absorbers existence. 2nd-The second Claim is on the back part of the vehicles and consists of a typical rea- lization by precise sequences of pairing and assembling (i/2=Fig :ia/3a and 2/2 Rg :iand 2) and by precise sequences of pairing and its sub-assemblings,like the following points from"A"to"C": .- "A"-The main forkSyst("A"),mounting or not the2 telescopic shock-absorbers inside the2 legs, is centrally welded on the back of the frameSyst(B)with its 2 legs lying on the vertical motion plane. .- "B"-The inclining 'right and left1 parallelogramSyst("D")is crosswise mounted respect to its main forkSystfA") and is made of 2 horizontal articulated long and narrow sides on top and on bottom and of 2vertical articulated narrow sides hinged(Y) together to obtain the inclinability. This inclining parallelogramSyst("D") with its 2 axesSystf'X") crosswise welded in the middle of the2 longer horizontal sides on top and on bottom, lying on the vertical motion plane and having at their ends the2.dual-joint("Z") fixed internally to the2 legs, used to support the2 not-steering axlesSyst(C') and their forksSyst(11F"+"R").
.- "C"-The 2 back forks/wheelsSyst("F"+"R") with their 2 not-steering axlesSyst("C") and combined to the breaking leveragesSyst("E") from the (M)handle-bar, is applied to the inclining parallelogramSystfD"). In conclusion of the 2nd claim on the back System, the 2 forks/wheelsSyst("F"+"R") for the SystemCA'V'D'VX") and or the System("P"+"D"+"X"), must be :
.a) parallel toward the motion direction, equidistant from the vertical frame(B) motion plane. Note: With the entire indining/steeringSystem, with 4 wheels, due to its typical realization by precise sequences of pairing in assembling and of pairing in Ks sub-assemblings, the vehicle in curve or in straight motion, has such a behavior that the 2 back forks/wheelsSyst- ("F"+"R") follow the same kind of inclining, pass on the same drive tracing whithout sliding.
.b) inclinable simultaneously due to the driving (M)handle-bar and leveragesSyst(E) actions, .c) absorbable only if the 2 back shock-absorbers exist inside the 2 pertinent legs. 3rd -The third Claim of the System referring to the original functionality of the idea.accor- ding to the2 main forksSyst(A &"A"), having the2 double legs lying on the vertical motion plane, are welded centrally on top(A) and the other("A"),if there is.centrally on the back of the frame-
Syst(B). Then the2 articulated sub-assemblies 'inclining parallelogramSyst(D&"D")'are crosswise mounted respect to the 2 main forksSyst(A&"A"), so in this manner we obtain the inclining functionality and also the shock-absorbing functionality if there are the shock-absorbers. In conclusion -This third Claim means that: the Systems, lying on the vertical motion plane the2 main forkSyst(A & "A'for the quadricycle) welded forward on top(A) and ("A")on the back of the frameSystem(B) wich crosswise support the inclining parallelogramSyst(D & "D"), provide to support completely the 4 axlesSyst(C & not-steering"C") and the forksSyst(F+R)& ("FV1R"). About the shock-absorbers, they must be inside the legs of the 2 main forksSyst(A &"A" for the quadricycle).The downward absorbing-cylinders should support 'up & down' the double dual-joint(Z&"Z") with their axesSyst(X &"X")and support their inclining parallelogramSyst(D&"D"). In this way on top.on the (M)handle-bar and on the back of the frame(B), shock-absorbing will be very efficient. 4th - The fourth Claim of the Systemfø Rg.i - or a) ), referring to other kind of the inclining parallelogramSyst(D &"D") as the : with the articulated inclining parallelogramSyst(D &"D") made like following = " the2 horizontal plate sides(LX), hinged to other2 vertical plate sides(L)", where each other sub-assemblies remains inalterable, permitting the articulated inclining parallelogramSyst(D & "D") to do its regular 'right and left' inclining function. 5th - The fifth claim of the System (2*2 Rg.i - or b). ), referring to other kind of the inclining parallelogramSyst(D &"D") as the : with the articulated inclining parallelogramSyst(D &"D")
