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 left ¹ 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( ¹¹ F"+"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)& ("FV ¹ R"). 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")

CONCLUDING : the vehicle built with 3 or 4 wheels is more stable when it is in stop mode, in straight motion, in curve and in bracking actions and also over the slippery or sandy roads. The Conclusions of all previous claims are summaryed in the Iast2 for the forksSyst(A&"A")and the forksSyst(P&"P") 'having or not inside the shock-absorbers' and for their parallelograms(D&"D").

120 Note : " The forksSyst(P&"P"), inside the inclining parallelogramSyst(D&"D")" has very narrow legs, almost coincident 'with or without the shock-absorbers' . Note : In case of presence of the shock-absorbers inside the 2 legs of the forks(A&"A")& (P&"P"), their 2.dual-joint(Z&"Z") of their relative asses(X &"X") of their inclining parallelograms- Syst(D&"D") must X hinge with the downward absorbing-cylinders of the same

125 shock-absorbers, so that shock-absorbing is very efficient.
