Abstract
Abstract A stabilizer for a vehicle having a chassis and transversely-positioned wheel supports mounted for vertical movement relative to the chassis. The stabilizer has a pair of levers and means for pivoting these levers to the chassis about horizontally spaced longitudinal axis. The levers are formed to dispose their normally lower ends adjacent to the wheel supports. Means are provided for slidably connecting the lever ends to the wheel supports to cause conjoint vertical displacement of the lever ends and the wheel supports. The levers are formed with juxtaposed normally upper ends and means are provided for pivotal connection of the upper ends to provide conjoint vertical displacement.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
150 words
A stabilizer for a vehicle having a chassis and tranversely-positioned wheel supports mounted for vertical movement relative to said chassis comprising: a pair of levers; means for pivoting said levers intermediate their ends to said chassis about horizontally spaced longitudinal extending axes; said levers being formed to dispose normally lower ends adjacent said wheel supports; means slidably connecting said lever ends to said wheel supports causing conjoint vertical displacement of said lever ends and said wheel supports and including first guide members and pivotal means for mounting said first guide members one to each of said wheel supports for rotation about a longitudinal axis, and second guide members mounted one on each lever end and mounted in slidable embrace with said first guide members; said levers being formed to provide juxtaposed normally upper ends; and means formed for pivotal connection of said upper ends to provide conjoint vertical displacement thereof.
Claim 2
Dependent Claim
150 words
A stabilizer for a vehicle having a chassis and tranversely-positioned wheel supports mounted for vertical movement relative to said chassis comprising: a pair of levers; means for pivoting said levers intermediate their ends to said chassis about horizontally spaced longitudinal extending axes; said levers being formed to dispose normally lower ends adjacent said wheel supports; means slidably connecting said lever ends to said wheel supports causing conjoint vertical displacement of said lever ends and said wheel supports and including first guide members and pivotal means for mounting said first guide members one to each of said wheel supports for rotation about a longitudinal axis, and second guide members mounted one on each lever end and mounted in slidable embrace with said first guide members; said levers being formed to provide juxtaposed normally upper ends; and means formed for pivotal connection of said upper ends to provide conjoint vertical displacement thereof.
Claim 3
Dependent Claim
19 words
The structure of claim 1, said pivotal means for each of said first guide members comprising a universal joint.
Claim 4
Dependent Claim
55 words
The structure of claim 1, one of said guide members having a substantially horizontally disposed transversely extending track and the other of said guide members having an elongated part mounted in slidable engagement with said track; and each said track and engaged part extending substantially perpendicular to a radius therefrom to said last-named associated axis.
Claim 5
Dependent Claim
19 words
The structure of claim 3, said pivotal means for each of said first guide members comprising a universal joint.
Claim 6
Dependent Claim
65 words
The structure of claim 1, said first-named means comprising: a supporting member and pivotal means for mounting said support member to said chassis for rotation about an axis extending longitudinally of said support member and with said support member extending substantially horizontally transversely of said chassis in superimposed relation to said wheel supports; and said first-named pivoting means connecting said levers to said support member.
Claim 7
Dependent Claim
32 words
The structure of claim 5, said upper lever ends being mounted in substantially vertically aligned relation; and a link member pivoted to said lever ends and providing a floating pivotal connection therebetween.
Claim 8
Dependent Claim
48 words
The structure of claim 5 for vehicles having longitudinally extending frame members adjacent opposite sides of said chassis; a pair of clamps adapted for attachment to said frame members; and said pivotal means for said support member comprising bearings and shafts mounted on said support member and clamps.
Claim 9
Dependent Claim
54 words
The structure of claim 7, each of said clamps comprising a plate confronting the opposite ends of said support member; said bearings being mounted one on each of said plates; and said shafts being mounted in coaxial alignment at and projecting from said opposite ends of said support member for journaling in said bearings.
Claim 10
Dependent Claim
34 words
The structure of claim 8 for channel-shaped vehicle frame members having an open interior and opposed sides; and a cam carried by said plates and movable into locking engagement with one of said sides.
Claim 11
Dependent Claim
34 words
The structure of claim 1, one of said levers comprising a plurality of sections; and means selectively interlocking said sections for unitary motion and for decoupling said sections for individual articulation disabling said stabilizer.
Claim 12
Dependent Claim
60 words
The structure of claim 10, said sections being pivotally connected; one of said sections providing said normally lower lever end; the other of said sections providing said normally upper lever end; and said selective locking means functioning to prevent and permit relative movement of said sections about their pivotal connections in the locked and decoupled positions of said sections respectively.
Claim 13
Dependent Claim
71 words
The structure of claim 11, said sections having portions substantially aligned in the relatively unloaded attitude of said vehicle; and said selective locking means comprising: a slide member mounted for reciprocation on one of said portions; a channel member mounted on the other of said portions in position to receive said slide member; and manually actuated means for displacing said slide member into and out of engagement with said channel member.
