Abstract
Abstract An improved adjustable control console for a vehicle or the like of the type including a base (16) for attachment to a vehicle (12), a head (18), rigid mounting links (30,38) pivotally interconnecting the base and the head in a manner like that of a parallelogram linkage (16,18,28,33,34,38,40,42) to allow fore and aft movement of the console, at least one control element (22) movably mounted on the console, a rigid control link (50) connected to the control element and extending therefrom towards the base and including the improvement wherein the links are selectively simultaneously extensible to allow adjustment of the spacing between the head and the base.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
92 words
An adjustable control console for a vehicle or the like including a base for attachment to a vehicle, a member, rigid mounting links pivotally interconnecting the base and the member in a manner like that of a parallelogram linkage to allow fore and aft movement of the member, at least one control element movably mounted on the member, and a rigid control link connected to the control element and extending therefrom toward said base, said links being selectively simultaneously extensible to allow adjustment of the spacing between said member and said base.
Claim 2
Dependent Claim
92 words
An adjustable control console for a vehicle or the like including a base for attachment to a vehicle, a member, rigid mounting links pivotally interconnecting the base and the member in a manner like that of a parallelogram linkage to allow fore and aft movement of the member, at least one control element movably mounted on the member, and a rigid control link connected to the control element and extending therefrom toward said base, said links being selectively simultaneously extensible to allow adjustment of the spacing between said member and said base.
Claim 3
Dependent Claim
13 words
The adjustable control console of claim 1 wherein said links comprise hydraulic cylinders.
Claim 4
Dependent Claim
33 words
The adjustable control console of claim 1 wherein said links comprise hydraulic cylinders, at least one of said mounting links comprising a master cylinder and the remainder of said links comprising slave cylinders.
Claim 5
Dependent Claim
121 words
The adjustable control console of claim 1 wherein said links comprise hydraulic cylinders, at least one of said mounting links comprising a master cylinder and the remainder of said links comprising slave cylinders, the cross sectional area of the fluid chamber(s) of said master cylinder(s) being equal to the sum of the cross sectional areas of the fluid chambers of said slave cylinders, and conduit means, interconnecting said fluid chambers, such that movement of said master cylinder(s) in one direction to decrease its volume will cause hydraulic fluid to be directed therefrom to the fluid chambers of said slave cylinders to increase their volume and to cause an equal movement of said slave cylinders in said one direction or vice versa.
Claim 6
Dependent Claim
27 words
The adjustable control console of claim 4 further including isolating means in said conduit means for normally preventing cross flow of hydraulic fluid between said slave cylinders.
