Abstract
A saw attachment mechanism includes at least one guide roller configured for releasable engagement with a track, a guide roller shaft and a guide roller pivot, each coupled to the guide roller, at least one pushrod configured for engagement with the guide roller shaft, and a cam shaft coupled to a handle. The guide roller can rotate around a guide roller axle. The guide roller pivot is coupled to the one guide roller to allow rotation of the guide roller and guide roller shaft toward and away from an engaged configuration. The pushrod can engage the guide roller shaft at a first end and the cam shaft at a second end. As the cam shaft is rotated, the pushrod slides to engage the guide roller shaft, to swing the guide roller shaft into an engaged position.
Claims16
A saw attachment mechanism for removably affixing a saw motor to a track, said attachment comprising:
- at least one guide roller shaft pivotally connected to a saw attachment mechanism body;
- wherein the at least one guide roller shaft is configured to pivot into an engaged configuration or disengaged configuration, wherein a pivot axis of the at least one roller shaft is perpendicular to a longitudinal axis of the at least one roller shaft;
- at least one guide roller configured for releasable engagement with the track, rotatably connected to the at least one guide roller shaft;
- at least one pushrod configured for engagement with the at least one guide roller shaft at a first end and a cam shaft at a second end of the at least one pushrod;
- and
- a handle coupled to the cam shaft, wherein operation of the handle causes the cam shaft to move the at least one pushrod, which engages the at least one guide roller shaft, biasing the at least one guide roller shaft toward the engaged configuration.
A track system comprising
- a track;
- and
- a saw attachment mechanism configured to removably affix a saw motor to the track, the saw attachment mechanism including:
- at least one guide roller shaft pivotally connected to a saw attachment mechanism body;
- wherein the at least one guide roller shaft is configured to pivot into an engaged configuration or disengaged configuration, wherein a pivot axis of the at least one roller shaft is perpendicular to a longitudinal axis of the at least one roller shaft;
- at least one guide roller configured for releasable engagement with the track, rotatably connected to the at least one guide roller shaft;
- at least one pushrod configured for engagement with the at least one guide roller shaft at a first end and a cam shaft at a second end of the at least one pushrod;
- and
- a handle coupled to the cam shaft, wherein operation of the handle causes the cam shaft to move the at least one pushrod, which engages the at least one guide roller shaft, biasing the at least one guide roller shaft toward the engaged configuration.
A wall saw comprising
- a saw motor;
- a track;
- and
- a saw attachment mechanism configured to removably affix the saw motor to the track, the saw attachment mechanism including:
- at least one guide roller shaft pivotally connected to a saw attachment mechanism body;
- wherein of the at least one guide roller shaft is configured to pivot into an engaged configuration or disengaged configuration, wherein a pivot axis of the at least one roller shaft is perpendicular to a longitudinal axis of the at least one roller shaft;
- at least one guide roller configured for releasable engagement with the track, rotatable connected to a respective at least one guide roller shaft;
- at least one pushrod configured for engagement with one of the at least one guide roller shaft at a first end and a cam shaft at a second end of the at least one pushrod;
- and
- a handle coupled to the cam shaft, wherein operation of the handle causes the cam shaft to move the at least one pushrod, which engages the at least one guide roller shaft, biasing the at least one guide roller shaft toward the engaged configuration.
