Push block for a woodworking apparatus

摘要

A push block for a woodworking tool comprises at least heel member at an end of the push block and the heel member is passively actuatable to an extended position to engage a trailing end surface of a work piece to advance the work piece by a working element. The push block also includes a wall member along a first side of the push block to serve as a barrier between a cutting element and an operator's hand. In addition, the push block includes a handle that is disposed obliquely relative to first and second sides and a longitudinal axis of the push block.

主权项

1. A push block for advancing a work piece on a cutting apparatus, comprising:
a main body portion having a flat bottom surface for engaging a surface of the work piece, a top surface, a first end, a second end and a longitudinal axis from the first end to the second end; a handle, disposed between the first and second ends, extending outward from the top surface of the main body portion; a first pair of heel members that are pivotally attached to the main body portion and disposed at the first or second end of the main body portion and the first heel members are aligned side by side and spaced apart, wherein each respective heel member has a surface and both surfaces are capable of engaging a first same trailing end surface of the work piece when extended, and the surfaces extend in the same plane and are disposed at an angle relative to the bottom surface of the main body portion; a second pair of heel members that are pivotally attached to the main body portion and disposed at the first or second end of the main body portion and the second heel members are aligned side by side and spaced apart, wherein each respective second heel member has a surface exposed for engaging a second same trailing end surface of the work piece when extended, and the surfaces extend in the same plane and are disposed at an angle relative to the bottom surface of the main body portion; and, wherein each heel member of the first pair and second pair are pivotal to an extended position and to a retracted position, and in the extended position the surface of each heel member is disposed at an angle relative to the bottom surface of the main body portion.
