Claim Text:
1. A security gate comprising a variable-width screen including a first panel adapted to lie in a doorway and mate with a first doorjamb bordering the doorway and a second panel mounted on the first panel for sliding movement relative to the first panel to mate with an opposing second doorjamb bordering the doorway to widen a width of the variable-width screen to abut the first and second doorjambs and span the doorway between the first and second doorjambs and, alternatively, to separate from the opposing second doorjamb to narrow the width of the variable-width screen to allow a caregiver to move the variable-width screen into or out of the doorway, and a hand-operated panel mover including a pivotable lock rod mounted on the first panel for pivotable movement about a first-panel pivot axis and a pivotable lock-release rod mounted on the second panel for pivotable movement about a second-panel pivot axis to engage and disengage the pivotable lock rod at the option of a caregiver, wherein the pivotable lock-release rod is formed to include a series of separate tab-receiver notches and the pivotable lock rod is formed to include a tab sized to fit into any of the tab-receiver notches formed in the pivotable lock-release rod when the pivotable lock-release rod and the pivotable lock rod are arranged to lie in side-by-side relation to one another to establish a panel-locking mode of the hand-operated panel mover so as to anchor the pivotable lock-release rod to the pivotable lock rod to apply panel-spreading forces to outer edges of the first and second panels to pressure-mount outer edges of the first and second panels of the variable-width screen to the first and second doorjambs bordering the doorway, and wherein the hand-operated panel mover further includes a rod coupler coupled to each of the pivotable lock-release rod and the pivotable lock rod and configured to provide means for tethering a free end of the pivotable lock rod to move back and forth along the pivotable lock-release rod to retain a free end of the tab included in the lock rod in close proximity to the series of tab-receiver notches formed in the lock-release rod without allowing movement of the tab into one of the tab-receiver notches during movement of the second panel relative to the first panel to widen or narrow the width of the variable-width screen after pivoting movement of the lock-release rod about the second-panel pivot axis away from a floor underlying the variable-width screen and away from a side-by-side relation with the pivotable lock rod to establish an obtuse included angle therebetween opening downwardly toward the floor during pivoting movement of the lock rod about the first-panel pivot axis away from the floor.
