Abstract
Pruners and Toppers have dual mode operation in that the blade is closed with a single squeeze or with multiple squeezes and a rotatable selector selects the desired mode. The blade has a rocker arm with ratchet teeth formed in a window in the arm. The scissor handle has a radius arm which ends in a pawl which can engage the ratchet nearer the pivot axis of the blade or further from it.
Claims14
A dual mode cutting tool including a first handle having a hand grip and a jaw member, a cutting member pivotally coupled to the first handle intermediate the hand grip and jaw member, and a second handle pivotally coupled to the first handle, wherein the cutting member has a blade arranged for engagement with the jaw member and a rocker arm with a plurality of ratchet teeth extending away from the cutting member pivot, further including a pawl linkage coupled from the second handle to an operative engagement with the ratchet teeth of the rocker arm and a mode selector movably supported by the second handle wherein a user engages and moves the mode selector between a first and second mode position and when the selector is in either of the mode positions, the selector acts upon the linkage to control a position of engagement of the linkage with the ratchet teeth when the tool is operated by manipulation of the handles.
A dual mode ratchet pruner including a first handle having a hand grip and a jaw member, a cutting member pivotally coupled to the first handle intermediate the hand grip and jaw member, and a second handle pivotally coupled to the first handle, wherein the cutting member has a blade arranged for engagement with the jaw member and a rocker arm formed with a ratchet window having ratchet teeth extending away from the cutting member pivot, the second handle movably supporting a mode selector and a pawl linkage coupling the second handle to the ratchet window of the rocker arm, the mode selector is engaged and moved by a user to a first mode configuration where the selector acts on the pawl linkage to bias the pawl linkage toward an end of the ratchet window closest the blade to engage respective ones of the ratchet teeth to define a single-action cutting mode and the mode selector is engaged and moved by the user to a second mode configuration where the selector acts on the pawl linkage to bias the pawl linkage toward an end of the ratchet window furthest from the blade to engage respective ones of the ratchet teeth to define a ratchet-action cutting mode.
A dual mode cutting tool including a first handle having a hand grip and a jaw member, a cutting member pivotally coupled to the first handle intermediate the hand grip and jaw member, and a second handle pivotally coupled to the first handle, wherein the cutting member has a blade arranged for engagement with the jaw member and a rocker arm with a plurality of ratchet teeth extending away from the cutting member pivot, further including a pawl linkage coupled from the second handle to an operative engagement with the ratchet teeth of the rocker arm, a mode selector movably supported on the second handle, and a spring acting between the pawl linkage and said second handle to bias said pawl linkage into contact with the mode selector wherein the mode selector acts upon the linkage to control a position of engagement of the linkage with the ratchet teeth when the tool is operated by manipulation of the handles.
