Abstract
Abstract A holder for supporting a piece of equipment above a surface has a column fixed to the surface, projecting upward therefrom, and having an upper end defining an inner horizontal pivot axis, an inner arm having an inner end pivoted at the inner axis on the column and an outer end defining an outer horizontal pivot axis, and an outer arm having an inner end pivoted at the outer axis on the inner-arm outer end and an outer end provided with a support for the piece of equipment. A link has an inner end seated in the upper end of the column at a location spaced a predetermined relatively long distance from the inner axis and an outer end seated in the inner end of the outer arm at a location space a predetermined relatively short distance from the outer axis. Thus as the inner axis is lifted the angle formed between the support and the horizontal increases.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
180 words
A holder for supporting a piece of equipment above a surface, the holder comprising: a column fixed to the surface, projecting upward therefrom, and having an upper end defining an inner horizontal pivot axis; an inner arm having an inner end pivoted at the inner axis on the column and an outer ned defining an outer horizontal pivot axis; an outer arm having an inner end pivoted at the outer axis on the inner-arm outer end and an outer end provided with a support for the piece of equipment, the support having a longitudinal axis; and a rigid and straight link having an inner end pivoted in the upper end of the column at a location spaced and fixed a predetermined long distance from the inner axis and an outer end pivoted in the inner end of the outer arm at a location spaced and fixed a predetermined short distance smaller than the long distance from the outer axis, whereby as the inner arm if pivoted the angle formed between the longitudinal axis of the support and the horizontal changes.
Claim 2
Dependent Claim
180 words
A holder for supporting a piece of equipment above a surface, the holder comprising: a column fixed to the surface, projecting upward therefrom, and having an upper end defining an inner horizontal pivot axis; an inner arm having an inner end pivoted at the inner axis on the column and an outer ned defining an outer horizontal pivot axis; an outer arm having an inner end pivoted at the outer axis on the inner-arm outer end and an outer end provided with a support for the piece of equipment, the support having a longitudinal axis; and a rigid and straight link having an inner end pivoted in the upper end of the column at a location spaced and fixed a predetermined long distance from the inner axis and an outer end pivoted in the inner end of the outer arm at a location spaced and fixed a predetermined short distance smaller than the long distance from the outer axis, whereby as the inner arm if pivoted the angle formed between the longitudinal axis of the support and the horizontal changes.
Claim 3
Dependent Claim
41 words
The holder defined in claim 1, further comprising a second such link separate from but parallel to the first-mentioned link and seated in the column and outer arm at second locations spaced like the first-mentioned locations differently from the respective axes.
Claim 4
Dependent Claim
36 words
The holder defined in claim 1 wherein the arms are movable between an extended end position with the axes spaced horizontally relatively far apart and a pushed-back end position with the axes spaced horizontally relatively closely.
Claim 5
Dependent Claim
28 words
The holder defined in claim 3 wherein the support for the equipment is generally horizontal in the extended position and oblique to the horizontal in the pushed-back position.
Claim 6
Dependent Claim
19 words
The holder defined in claim 3 wherein the arms and column have abutments that meet in the end positions.
Claim 7
Dependent Claim
32 words
The holder defined in claim 3 wherein in the pushed-back position the inner arm is upright and aligned with the column and in the extended position the inner arm is generally horizontal.
