Abstract
Abstract A spring-controlled structure operatively connected between a corresponding vertically shiftable wheel of a vehicle and frame and body of an associated vehicle and functioning to increasingly yieldingly resist upward motion of body and frame of the associated vehicle from a predetermined position when the vehicle is in a stationary position. The structure increasingly yieldingly resists the distance of separation between the vertically shiftable wheel and a predetermined position of vertical travel of the vertically shiftable body in an up movement past the predetermined stationary rebound point. However, the structure does effectively slow the downward motion of the vertically shiftable wheel and increasingly speeds up the rebound to the original static or predetermined position between the vertically shiftable frame and vertically shiftable wheel. The structure does not aid in laden weight carrying capacity of the associated vehicle, but does effectively control laden weight and high center of gravity laden weight by increasingly yieldingly resisting the frame and body of associated vehicle in any upward and side-to-side motion of high loads. Also, the structure does effectively control the upward movement of an associated vehicle without weight other than that of the associated vehicle.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
224 words
In combination with a vehicle of the type including a support structure from which a wheel is journaled and supported from a frame structure of said vehicle for generally vertical shifting relative thereto, means yieldably biasing said frame structure upwardly relative to said support structure for increasingly shock yieldingly cushioning support of the frame structure from the support structure, a roll and sway control system including a first arm stationarily supported from one of said structures and a second arm pivotally supported at one end portion from said first arm for oscillation relative thereto about an axis extending transversely of said second arm and swinging movement of the other end portion of said second arm toward and away from an opposing portion of said first arm, said system including means establishing a limit of swinging of said second arm in a first direction in which said other end portion moves away from said opposing portion, means connected between said arms yieldingLy biasing said second arm in said first direction, and motion-transmitting means operatively connected between the other end portion of said second arm and the other of said structures operative to hold said other end portion against movement away from said other of said structures in response to upward movement of said frame structure relative to said support structure past a predetermined position thereof.
Claim 2
Dependent Claim
224 words
In combination with a vehicle of the type including a support structure from which a wheel is journaled and supported from a frame structure of said vehicle for generally vertical shifting relative thereto, means yieldably biasing said frame structure upwardly relative to said support structure for increasingly shock yieldingly cushioning support of the frame structure from the support structure, a roll and sway control system including a first arm stationarily supported from one of said structures and a second arm pivotally supported at one end portion from said first arm for oscillation relative thereto about an axis extending transversely of said second arm and swinging movement of the other end portion of said second arm toward and away from an opposing portion of said first arm, said system including means establishing a limit of swinging of said second arm in a first direction in which said other end portion moves away from said opposing portion, means connected between said arms yieldingLy biasing said second arm in said first direction, and motion-transmitting means operatively connected between the other end portion of said second arm and the other of said structures operative to hold said other end portion against movement away from said other of said structures in response to upward movement of said frame structure relative to said support structure past a predetermined position thereof.
Claim 3
Dependent Claim
46 words
The combination of claim 1 wherein said means connected between said second arm and said other structure comprises one-way motion-transmitting means ineffective to afford any control on said other end portion in the opposite direction upon downward movement of said frame structure past said predetermined position.
Claim 4
Dependent Claim
23 words
The combination of claim 2 wherein said means connected between said second arm and said other structure comprises an elongated flexible tension member.
Claim 5
Dependent Claim
30 words
The combination of claim 3 wherein at least one end of said tension member includes means operative to adjust the effective length thereof, whereby said predetermined position may be adjusted.
Claim 6
Dependent Claim
13 words
The combination of claim 1 wherein said one structure comprises said frame structure.
Claim 7
Dependent Claim
13 words
The combination of claim 1 wherein said one structure comprises said support structure.
Claim 8
Dependent Claim
109 words
The combination of claim 1 wherein said first arm comprises one arm element of a generally C-shaped arm member including a pair of generally parallel arm elements interconnected at one pair of corresponding ends by means of a connecting arm element extending therebetween, one of said arm elements comprising elongated channel member opening toward the other arm element, said one end of said second arm being pivotally secured in the end of said one arm element adjacent said connecting arm element, said limit-establishing means comprising the other end of said one arm element with which the other end of said second arm is engageable when in said limit position.
Claim 9
Dependent Claim
36 words
The combination of claim 7 wherein said biasing means comprises a compression spring interposed between the other end of said second arm and the end of said one arm element remote from said connecting arm element.
Claim 10
Dependent Claim
25 words
The combination of claim 8 wherein said arm member is supported from said frame structure and said motion-transmitting means comprises an elongated flexible tension member.
Claim 11
Dependent Claim
47 words
The combination of claim 1 wherein said first arm comprises an upstanding arm member and said biasing means comprises a compression spring interposed between the other end of said second arm and the end of said first arm remote from said one end of said second arm.
Claim 12
Dependent Claim
92 words
The combination of claim 1 wherein said second arm, when in said limit position is disposed at generally right angles relative to said first arm, said limit-establishing means including an elongated articulated link assembly including a pair of link sections with one pair of adjacent ends pivotally secured together and the other pair of remote ends of said link sections pivotally secured to the remote end portions of said first and second arms, said link sections being disposed in fully relatively extended positions when said second arm is in its limit position.
Claim 13
Dependent Claim
36 words
The combination of claim 11 including means acting upon the adjacent ends of said link sections to urge the latter laterally of a plane containing the pivot axes of the remote ends of said link sections.
Claim 14
Dependent Claim
15 words
The combination of claim 12 wherein said first arm is supported from said support structure.
Claim 15
Dependent Claim
28 words
The combination of claim 13 wherein said motion-transmitting means comprises an elongated flexible tension member connected between said support portion and the other end of said second arms.
