Abstract
A dual nip release mechanism includes: a rigid actuator body including a tail portion with a handle and a pivotally-mounted head portion having a nose member extending therefrom; a rocker arm pivotally mounted about a rocker arm shaft, the rocker arm having a proximal end for engagement with part of the nose member and a distal end engaged with a first shaft; and legs hingedly connected to the tail portion, each leg having a foot engaged with a second shaft and a heel for camming engagement with a fixed plate. During use, actuation of the handle causes simultaneous movement of the first and second shafts from a nip closed position to a nip open position via pivoting of the rocker arm and simultaneous camming engagement of the heel with the fixed plate.
Claims19
A dual nip release mechanism for a printer, said printer having first and second shafts engaged with respective complementary shafts to define dual nips, the dual nip release mechanism comprising:
- a rigid actuator body including a tail portion having a handle for user actuation and a pivotally-mounted head portion having a nose member extending therefrom;
- a rocker arm pivotally mounted about a rocker arm shaft, the rocker arm having a proximal end for engagement with part of the nose member and a distal end engaged with the first shaft;
- and
- one or more legs hingedly connected to the tail portion, each leg having a foot engaged with the second shaft and a heel for camming engagement with a fixed plate,
- wherein, during use, actuation of the handle causes simultaneous movement of the first and second shafts from a nip closed position to a nip open position via pivoting of the rocker arm and simultaneous camming engagement of the heel with the fixed plate.
A printer comprising:
- a first shaft engaged with a complementary first shaft to define a first nip;
- a second shaft engaged with a complementary second shaft to define a second nip;
- and
- a dual nip release mechanism for opening and closing the first and second nips, the dual nip release mechanism comprising:
- a rigid actuator body including a tail portion having a handle for user actuation and a pivotally-mounted head portion having a nose member extending therefrom;
- a rocker arm pivotally mounted about a rocker arm shaft, the rocker arm having a proximal end for engagement with part of the nose member and a distal end engaged with the first shaft;
- and
- one or more legs hingedly connected to the tail portion, each leg having a foot engaged with the second shaft and a heel for camming engagement with a fixed plate, wherein, during use, actuation of the handle causes simultaneous movement of the first and second shafts from a nip closed position to a nip open position via pivoting of the rocker arm and simultaneous camming engagement of the heel with the fixed plate.
