Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
239 words
In a hydraulic chair structure of the type used by barbers and beauticians comprising a pedestal engaging the floor, a piston having one end received in said pedestal for relative vertical hydraulic movement with respect to said pedestal and a chair mounted on the other end of said piston, the improvement comprising: a. a rigid mounting ring coaxially surrounding said piston with a close tolerance for rotation thereabout, said mounting ring having a lower end surface lying in a plane normal to the axis thereof; b. a rigid support ring coaxially surrounding said piston and rigidly fixed thereto at said other end thereof beneath said mounting ring and supporting said mounting ring thereon immediately adjacent said chair, said support ring having an upper end surface lying in a plane normal to the axis thereof with said upper end surface of said support ring slidably abutting the lower end surface of said mounting ring; c. means rigidly fixing said rigid support ring to said piston; d. an elongated support arm having one end rigidly mounted on said mounting ring and a first portion extending from said one end of said support arm normal to the axis of said mounting ring; said support arm having a second portion extending upwardly from said first portion substantially parallel to the axis of said mounting ring to a free end; and e. means mounting an accessory on said free end of said support arm.
Claim 2
Dependent Claim
239 words
In a hydraulic chair structure of the type used by barbers and beauticians comprising a pedestal engaging the floor, a piston having one end received in said pedestal for relative vertical hydraulic movement with respect to said pedestal and a chair mounted on the other end of said piston, the improvement comprising: a. a rigid mounting ring coaxially surrounding said piston with a close tolerance for rotation thereabout, said mounting ring having a lower end surface lying in a plane normal to the axis thereof; b. a rigid support ring coaxially surrounding said piston and rigidly fixed thereto at said other end thereof beneath said mounting ring and supporting said mounting ring thereon immediately adjacent said chair, said support ring having an upper end surface lying in a plane normal to the axis thereof with said upper end surface of said support ring slidably abutting the lower end surface of said mounting ring; c. means rigidly fixing said rigid support ring to said piston; d. an elongated support arm having one end rigidly mounted on said mounting ring and a first portion extending from said one end of said support arm normal to the axis of said mounting ring; said support arm having a second portion extending upwardly from said first portion substantially parallel to the axis of said mounting ring to a free end; and e. means mounting an accessory on said free end of said support arm.
Claim 3
Dependent Claim
86 words
In a hydraulic chair structure as claimed in claim 1 wherein said mounting ring has an upper end surface lying in a plane parallel to the plane of said lower end surface thereof, and wherein a second rigid support ring coaxially surrounds said piston above said mounting ring, said second rigid support ring having a lower end surface lying in a plane normal to the axis thereof with said lower end surface of said support ring slidably abutting said upper end surface of said mounting ring.
Claim 4
Dependent Claim
31 words
In a hydraulic chair structure as claimed in claim 1 wherein said first portion of said elongated support arm is telescopic and includes means for rigidly maintaining a selected telescoped position.
Claim 5
Dependent Claim
35 words
In a hydraulic chair structure as claimed in claim 1 wherein said means mounting an accessory on said free end of said support is telescopic and includes means for rigidly maintaining a selected telescoped position.
Claim 6
Dependent Claim
68 words
In a hydraulic chair structure as claimed in claim 3 wherein said elongated support arm is tubular and said telescopic first portion thereof includes a rigid rod adapted to be received within said tubular elongated support arm, one end of said rigid rod being rigidly fixed to said mounting ring and said rigid rod projecting from the side surface of said mounting ring normal to the axis thereof.
Claim 7
Dependent Claim
61 words
In a hydraulic chair structure as claimed in claim 1 wherein said elongated support arm is tubular and said means mounting an accessory on said free end of said support arm comprises a body extending in a given plane with a rod adapted to be received within the free end of said tubular support arm extending normally to said given plane.
Claim 8
Dependent Claim
23 words
In a hydraulic chair structure as claimed in claim 1 wherein said rigid mounting ring has an axial length of about 23/4 inches.
Claim 9
Dependent Claim
23 words
In a hydraulic chair structure as claimed in claim 7 wherein said rigid support ring has an axial length of about 3/8 inch.
Claim 10
Dependent Claim
