Treatment chair having improved movable arm support devices

Claim 2

In a treatment chair having a seat rest and a back rest for receiving a patient for treatment by an operator; the improvement of movable arm support and retaining devices characterized by their ability to move for easy access to and from the side of the chair by the patient and easy access to the seated patient by the operator, said movable arm support devices comprising: generally horizontally-extending, lower arm rest means including means mounting said lower arm rest on said chair for movement from a first position in which said arm rest is generally parallel with the side edge of said seat rest for supporting the lower arm of the seated patient from downward movement to a second position in which said arm rest extends generally outwardly from the side edge of said seat rest of said chair for easy access to and from said chair from the side thereof by the patient; and generally horizontally-extending, upper arm rest means mounted on the side edge of said back rest of said chair and extending forwardly of said chair therefrom in a generally arcuate first position for retaining the upper arm of the seated patient from rearward and outward movement, said upper arm rest means comprising a plurality of interconnected segments including one-way means pivotally connecting said segments to each other for pivotal movement of said upper arm rest to other positions toward the seated patient and toward the medial portion of said chair only and not away from the seated patient beyond said first position for allowing the operator to move said upper arm rest closer to the patient for closer access to the seated patient while providing a retainer against outward movement of said upper arm rest.

Claim 3

In a treatment chair having a seat rest and a back rest and upper retaining arm rest means for receiving a patient for treatment by an operator; the improvement of generally horizontally-extending, lower arm rest means including means pivotally mounting said lower arm rest on said chair for movement from a first position in which said arm rest is generally parallel with the side edge of said seat rest of said chair for supporting the lower arm of the seated patient for downward movement to a second position in which said arm rest extends generally outwardly from the side edge of said seat rest of said chair for permitting easy access to and from said chair from the sidE thereof by the patient, said arm rest including a generally horizontally-extending support portion forming a part of said arm rest and having an upper generally flat surface for receiving the lower portion of the arm of a seated patient, and said means mounting said arm rest on said chair comprises: a side frame portion carried by said chair and defining a hollow, downwardly extending, generally cylindrical receptacle for receiving said arm rest; a hollow downwardly extending mounting portion forming a part of said arm rest and including a lower generally cylindrical portion of less cross-sectional dimensions than said receptacle in said frame portion for being received by said receptacle and allowing pivotal movement therebetween; means for holding said lower portion of said mounting portion in said receptacle; and stop means for positioning said lower arm rest means in said first and second positions comprising an outwardly extending flange portion having notches therein and being carried by said mounting portion of said lower arm rest means, a pin member mounted in said side frame portion of said chair and extending toward said flange portion for reception by a respective one of said notches when said lower arm rest means is moved to said first and second positions and means biasing said flange portion and said notches into engagement with said pin member.

Claim 4

In a treatment chair having a seat rest and a back rest and upper retaining arm rest means for receiving a patient for treatment by an operator; the improvement of generally horizontally-extending, lower arm rest means including means pivotally mounting said lower arm rest on said chair for movement from a first position in which said arm rest is generally parallel with the side edge of said seat rest of said chair for supporting the lower arm of the seated patient for downward movement to a second position in which said arm rest extends generally outwardly from the side edge of said seat rest of said chair for permitting easy access to and from said chair from the sidE thereof by the patient, said arm rest including a generally horizontally-extending support portion forming a part of said arm rest and having an upper generally flat surface for receiving the lower portion of the arm of a seated patient, and said means mounting said arm rest on said chair comprises: a side frame portion carried by said chair and defining a hollow, downwardly extending, generally cylindrical receptacle for receiving said arm rest; a hollow downwardly extending mounting portion forming a part of said arm rest and including a lower generally cylindrical portion of less cross-sectional dimensions than said receptacle in said frame portion for being received by said receptacle and allowing pivotal movement therebetween; means for holding said lower portion of said mounting portion in said receptacle; and stop means for positioning said lower arm rest means in said first and second positions comprising an outwardly extending flange portion having notches therein and being carried by said mounting portion of said lower arm rest means, a pin member mounted in said side frame portion of said chair and extending toward said flange portion for reception by a respective one of said notches when said lower arm rest means is moved to said first and second positions and means biasing said flange portion and said notches into engagement with said pin member.

Claim 5

In a treatment chair, having a seat rest and a back rest and lower arm rest means for receiving a patient for treatment by an operator; the improvement of generally horizontally-extending, upper retaining arm rest means mounted on the side edge of said back rest of said chair and extending forwardly of said chair therefrom in a generally arcuate first position for retaining the upper rest of the seated patient from rearward and outward movement, said upper arm rest means comprising: a plurality of interconnected segments including one-way means pivotally connecting said segments to each other for pivotal movement of said arm rest to other positions toward the seated patient and toward the medial portion of said chair only and not away from the seated patient beyond said first position for the operator to move said arm rest closer to the patient allowing closer access to the seated patient by the operator while providing a retainer against outward movement of said arm rest.

Claim 6

In a treatment chair, having a seat rest and a back rest and lower arm rest means for receiving a patient for treatment by an operator; the improvement of generally horizontally-extending, upper retaining arm rest means mounted on the side edge of said back rest of said chair and extending forwardly of said chair therefrom in a generally arcuate first position for retaining the upper rest of the seated patient from rearward and outward movement, said upper arm rest means comprising: a plurality of interconnected segments including one-way means pivotally connecting said segments to each other for pivotal movement of said arm rest to other positions toward the seated patient and toward the medial portion of said chair only and not away from the seated patient beyond said first position for the operator to move said arm rest closer to the patient allowing closer access to the seated patient by the operator while providing a retainer against outward movement of said arm rest.

Claim 7

In a treatment chair, as set forth in claim 3, in which each of said segments includes a plate means having hinge means on each side thereof for cooperating connection with hinge means on other plate means, each of said hinge means including stop means for abutting engagement with cooperating hinge means to permit pivotal movement of said segments in one direction only, and in which said plurality of connected segments include a common, flexible covering means surrounding said segments and providing a retaining surface for the upper arm of the seated patient.
