Reclining chair with push-button actuator mechanism

Claim 2

A push-button actuator mechanism for use in a reclining chair that includes a seat, a backrest, a footrest, opposite chair sides, a chair base, and a carriage mechanism mounting the seat, backrest, footrest and chair sides above the chair base and enables them to move relative to each other and to the chair base so as to cause the reclining chair to be repositioned from an upright positioning to a reclined positioning and vice versa, said push-button actuator mechanism being capable of activating the carriage mechanism so as to reposition the reclining chair from its upright positioning to a reclined positioning, said push-button actuator mechanism including a support plate which is attachable to the front stump of one of said chair sides so as to extend towards the back of said reclining chair, said support plate having a side which faces outwardly of said reclining chair, a pin bracket attached to said side of said support plate, first and second anchoring brackets attached to said side of said support plate, an actuator arm pivotally connected to said pin bracket to be movable in a first plane, said actuator arm including a first end, a second end, and a step-like indentation near its second end, a first spring means connected between said first end of said actuator link and said first anchoring bracket, a drive arm pivotally connected at its first end to said second end of said actuator arm, the second end of said drive arm being pivotally connectable to a control link of said carriage mechanism, a hawkbill latch arm pivotally connected to said second anchoring bracket so as to be movable in a second plane which is generally perpendicular to said first plane, said latch arm including a first end having a curved lip projecting towards said support plate and a second end mounting a button projecting away from said support plate, said curved lip being engageable with said step-like indentation in said actuator arm, and a second spring means connected to said hawkbill latch arm to bias said hawkbill latch arm about said second anchoring bracket such that its first end tends to move towards said support plate.

Claim 3

The push-button actuator mechanism as defined in claim 1, wherein said first spring means comprises a helical spring.

Claim 4

The push-button actuator mechanism as defined in claim 1 wherein said second spring means comprises a torsional spring.

Claim 5

In a reclining chair which includes a seat, a backrest, a footrest, opposite chair sides, a chair base and a carriage mechanism mounting the seat, backrest, footrest and opposite chair sides above the chair and enables them to move relative to each other and to the chair base so as to cause the reclining chair to be repositioned from an upright positioning to a reclined positioning and vice versa, the improvement wherein said reclining chair includes a push-button actuator mechanism which is capable of operating the carriage mechanism so as to reposition the reclining chair from its upright positioning to a reclined positioning, said bush-buttom actuator mechanism including a support plate which is attachable to the front stump of one of said chair sides so as to extend towards the back of said reclining chair, said support plate having a side which faces outwardly of said reclining chair, a pin bracket attached to said side of said support plate, first and second anchoring brackets attached to said side of said support plate, an actuator arm pivotally connected to said pin bracket to be movable in a first plane, said actuator arm including a first end, a second end, and a step-like indentation near its second end, a first spring means connected between said first end of said actuator link and said first anchoring bracket, a drive arm pivotally connected at its first end to said second end of said actuator arm, the second end of said drive arm being pivotally connectable to a control link of said carriage mechanism, a hawkbill latch arm pivotally connected to said second anchoring bracket so as to be movable in a second plane which is generally perpendicular to said first plane, said latch arm including a first end having a curved lip projecting towards said support plate and a second end mounting a button projecting away from said support plate, said curved lip being engageable with said step-like indentation in said actuator arm, and a second spring means connected to said hawkbill latch arm to bias said hawkbill latch arm about said second anchoring bracket such that its first end tends to move towards said support plate.

Claim 6

In a reclining chair which includes a seat, a backrest, a footrest, opposite chair sides, a chair base and a carriage mechanism mounting the seat, backrest, footrest and opposite chair sides above the chair and enables them to move relative to each other and to the chair base so as to cause the reclining chair to be repositioned from an upright positioning to a reclined positioning and vice versa, the improvement wherein said reclining chair includes a push-button actuator mechanism which is capable of operating the carriage mechanism so as to reposition the reclining chair from its upright positioning to a reclined positioning, said bush-buttom actuator mechanism including a support plate which is attachable to the front stump of one of said chair sides so as to extend towards the back of said reclining chair, said support plate having a side which faces outwardly of said reclining chair, a pin bracket attached to said side of said support plate, first and second anchoring brackets attached to said side of said support plate, an actuator arm pivotally connected to said pin bracket to be movable in a first plane, said actuator arm including a first end, a second end, and a step-like indentation near its second end, a first spring means connected between said first end of said actuator link and said first anchoring bracket, a drive arm pivotally connected at its first end to said second end of said actuator arm, the second end of said drive arm being pivotally connectable to a control link of said carriage mechanism, a hawkbill latch arm pivotally connected to said second anchoring bracket so as to be movable in a second plane which is generally perpendicular to said first plane, said latch arm including a first end having a curved lip projecting towards said support plate and a second end mounting a button projecting away from said support plate, said curved lip being engageable with said step-like indentation in said actuator arm, and a second spring means connected to said hawkbill latch arm to bias said hawkbill latch arm about said second anchoring bracket such that its first end tends to move towards said support plate.

Claim 7

In a reclining chair as defined in claim 4 wherein said first spring means comprises a helical spring.

Claim 8

In a reclining chair as defined in claim 4 wherein said second spring means comprises a torsional spring.

Claim 9

In a reclining chair as defined in claim 4 wherein one of said chair sides includes a front stump, and wherein said support plate is attached to said front stump.

Claim 10

In a reclining chair as defined in claim 7 wherein said one of said chair sides includes material forming lateral sides, and wherein said button extends through an opening in the material of the lateral side which faces outwardly of said reclining chair.
