Abstract
Abstract In a recliner chair having a handle operated footrest including footrest mechanisms on opposite sides of the chair, an improved linkage is provided for connecting the handle on one side of the chair with the footrest mechanism on that side of the chair to operate the same and for connecting the handle to the footrest mechanism on the other side of the chair to operate the same through means of a torque tube interconnecting the footrest mechanisms.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
216 words
In a handle-operated recliner chair, including a footrest movable between a retracted position adjacent the front of the chair, and an extended position projected forwardly from the front of the chair, the footrest including two footrest linkages mounted on opposite sides of the chair for extending and retracting the footrest relative to the chair and a torque transmitting member extending across the chair interconnecting said footrest linkages such that actuation of one footrest linkage will be transmitted to the other footrest linkage; the improvement comprising hand-operated linkage means connected to said one footrest linkage for actuating the same between extended and retracted positions, including a handle link mounted for pivotal movement about a first horizontal axis, a manual operating handle connected to said handle link for pivoting the same about said first axis, a second link connected to said torque transmitting member and being mounted for pivotal movement about a second horizontal axis located below said first horizontal axis, and linkage means interconnecting said handle link and said second link for transmitting motion from said handle link to said second link, and wherein one of said handle link and second link is connected to said one footrest linkage for actuating the same when the handle is moved to pivot said handle link about said first axis.
Claim 2
Dependent Claim
216 words
In a handle-operated recliner chair, including a footrest movable between a retracted position adjacent the front of the chair, and an extended position projected forwardly from the front of the chair, the footrest including two footrest linkages mounted on opposite sides of the chair for extending and retracting the footrest relative to the chair and a torque transmitting member extending across the chair interconnecting said footrest linkages such that actuation of one footrest linkage will be transmitted to the other footrest linkage; the improvement comprising hand-operated linkage means connected to said one footrest linkage for actuating the same between extended and retracted positions, including a handle link mounted for pivotal movement about a first horizontal axis, a manual operating handle connected to said handle link for pivoting the same about said first axis, a second link connected to said torque transmitting member and being mounted for pivotal movement about a second horizontal axis located below said first horizontal axis, and linkage means interconnecting said handle link and said second link for transmitting motion from said handle link to said second link, and wherein one of said handle link and second link is connected to said one footrest linkage for actuating the same when the handle is moved to pivot said handle link about said first axis.
Claim 3
Dependent Claim
17 words
The improvement defined in claim 1 wherein said second link is connected to said one footrest linkage.
Claim 4
Dependent Claim
73 words
The improvement defined in claim 1 wherein said handle link includes a flange portion projecting outwardly of the chair from the plane of the handle link and wherein said handle is fixed to said flange portion; and wherein said second link has a flange portion projecting inwardly of the chair from the plane of the second link and wherein said torque transmitting member is fixed to said flange portion of said second link.
Claim 5
Dependent Claim
58 words
The improvement defined in claim 3 wherein said handle link includes a generally L-shaped major portion and wherein said second link includes a generally V-shaped major portion, and wherein said linkage means interconnecting said handle link and said second link is a short link pivotally connected to ends of said major portions of said handle and second links.
Claim 6
Dependent Claim
51 words
The improvement defined in claim 1 further including first stop means for limiting movement of the handle in one direction to determine the fully extended position of the footrest, and second stop means for limiting movement of the handle in an opposite direction to determine the retracted position of the footrest.
Claim 7
Dependent Claim
42 words
The improvement defined in claim 5 wherein said first stop means includes said linkage means interconnecting said handle and second links and wherein said second stop means includes a stop fixed relative to the chair to be engaged by said second link.
Claim 8
Dependent Claim
46 words
The improvement defined in claim 6 wherein said chair includes a mounting member fixed to a frame portion of the chair, and wherein said handle link and second link are pivotally mounted to said mounting member, and wherein said stop is fixed to said mounting member.
Claim 9
Dependent Claim
214 words
For use in combination with a handle-operated recliner chair including a footrest movable between extended and retracted positions, and two footrest linkages on opposite sides of the chair for moving the footrest between said extended and retracted positions, and a torque transmitting member interconnecting said footrest linkages to transmit motion from one footrest linkage to the other footrest linkage; a manually operated handle and linkage assembly for manually operating one of said footrest linkages, the assembly comprising a first handle link adapted to be pivotally mounted relative to the chair for movement about a first horizontal axis, a handle connected to said handle link to pivot the same about said first horizontal axis, a second link adapted to be pivotally mounted relative to the chair for movement about a second horizontal axis and to be fixed to the torque transmitting member of the chair, a third link interconnecting said handle link and said second link to transmit motion from the handle link to said second link, and a fourth link having one end pivotally connected to one of said handle link and second link and an opposite end adapted to be pivotally connected to said one footrest linkage to operate the same in response to movement of said handle link about said first axis.
Claim 10
Dependent Claim
214 words
For use in combination with a handle-operated recliner chair including a footrest movable between extended and retracted positions, and two footrest linkages on opposite sides of the chair for moving the footrest between said extended and retracted positions, and a torque transmitting member interconnecting said footrest linkages to transmit motion from one footrest linkage to the other footrest linkage; a manually operated handle and linkage assembly for manually operating one of said footrest linkages, the assembly comprising a first handle link adapted to be pivotally mounted relative to the chair for movement about a first horizontal axis, a handle connected to said handle link to pivot the same about said first horizontal axis, a second link adapted to be pivotally mounted relative to the chair for movement about a second horizontal axis and to be fixed to the torque transmitting member of the chair, a third link interconnecting said handle link and said second link to transmit motion from the handle link to said second link, and a fourth link having one end pivotally connected to one of said handle link and second link and an opposite end adapted to be pivotally connected to said one footrest linkage to operate the same in response to movement of said handle link about said first axis.
Claim 11
Dependent Claim
17 words
The assembly defined in claim 8 wherein said fourth link is pivotally connected to said second link.
Claim 12
Dependent Claim
20 words
