Abstract
A motorized saw assembly includes a base assembly having a workpiece support surface which defines a workpiece surface plane, an upper support assembly configured to support a saw blade, and a hinge assembly including a first linkage assembly and a second linkage assembly. The upper support assembly is configured to move between a first position, whereat the first linkage assembly and the second linkage assembly extend substantially perpendicular to the workpiece surface plane, and a second position, whereat the first linkage assembly and the second linkage assembly extend over the workpiece support surface.
Claims10
A motorized saw assembly comprising:
- a base assembly including a workpiece support surface which defines a workpiece surface plane;
- an upper support assembly configured to support a saw blade;
- a hinge assembly including a first linkage assembly and a second linkage assembly, the first linkage assembly including a first rear linkage having a first rear linkage body portion and a first front linkage having a first front linkage body portion, the first front linkage pivotably connected to the first rear linkage, and the second linkage assembly including a second rear linkage having a second rear linkage body portion and a second front linkage having a second front linkage body portion, the second front linkage pivotably connected to the second rear linkage,
- wherein the upper support assembly is configured to move between a first position, whereat the first linkage assembly and the second linkage assembly extend substantially perpendicular to the workpiece surface plane, and a second position, whereat the first linkage assembly and the second linkage assembly extend over the workpiece support surface,
- wherein, in the first position, the first rear linkage body portion and the second rear linkage body portion extend in a first plane that is perpendicular to the workpiece surface plane, and the first front linkage body portion and the second front linkage body portion extend in a second plane that is perpendicular to the workpiece surface plane,
- wherein the first front linkage and the first rear linkage pivot in a third plane that is transverse to the workpiece surface plane, the first front linkage having a first longitudinal axis extending centrally from a first end of the first front linkage to a second opposite end of the first front linkage at which the first front linkage connects to the first rear linkage, the first rear linkage having a second longitudinal axis extending centrally from a first end of the first rear linkage, at which the first rear linkage connects to the first front linkage, to a second opposite end of the first rear linkage, and both the first and second longitudinal axes are entirely in the third plane, and
- wherein the second front linkage and the second rear linkage pivot in a fourth plane that is transverse to the workpiece surface plane, the second front linkage having a third longitudinal axis extending centrally from a first end of the second front linkage to a second opposite end of the second front linkage at which the second front linkage connects to the second rear linkage, the second rear linkage having a fourth longitudinal axis extending centrally from a first end of the second rear linkage, at which the second rear linkage connects to the second front linkage, to a second opposite end of the second rear linkage, and both the third and fourth longitudinal axes are entirely in the fourth plane.
