Abstract

A sanding apparatus for finishing an exterior surface of an elongated work piece includes a support structure, a belt-sander, and a mounting bracket to movably mount the belt-sander to the support structure. The bracket is attached to the belt-sander and includes a guide mechanism movably mounted to one or more guide rails of the support structure. The bracket also includes a hinge mechanism that permits the belt-sander to pivot between a first position where an abrasive surface of the belt-sander does not contact the exterior surface of the work piece, and a second position where the abrasive surface contacts the exterior surface of the work piece. In operation, a user moves the belt-sander along the guide rails while the abrasive surface contacts the exterior surface of the work piece to smooth the exterior surface of the work piece.

Claims17

Dependent claims

A sanding apparatus for finishing an exterior surface of an elongated work piece comprising:

a belt-sander having an abrasive surface to contact an exterior surface of an elongated work piece;
a support structure comprising:
a first guide rail positioned above the belt-sander;
and
a second guide rail positioned behind the belt-sander;
and
a mounting bracket fixedly mounted to the belt-sander and configured to movably connect the belt-sander to the first and second guide rails such that the belt-sander moves along a longitudinal axis of the elongated work piece, the mounting bracket comprising:
a first guide mechanism having a first guide wheel configured to move along a horizontal surface of the first guide rail;
a second guide mechanism having a second guide wheel configured to move along a vertical surface of the second guide rail;
and
a hinge configured to allow the belt-sander to pivot between a first position where the abrasive surface is not in contact with the exterior surface of the elongated work piece, and a second position where the abrasive surface contacts the exterior surface of the elongated work piece in a direction transverse to a longitudinal axis of the elongated work piece.

A sanding apparatus for finishing an exterior surface of an elongated work piece comprising:

a support structure having first and second guide rails;
a belt-sander having an abrasive surface to contact an exterior surface of an elongated work piece, the belt-sander being pivotable between a first position where the abrasive surface is not in contact with the exterior surface of the elongated work piece, and a second position where the abrasive surface is in contact with the exterior surface of the work piece in a direction transverse to a longitudinal axis of the elongated work piece;
a mounting bracket fixedly mounted to the belt-sander and configured to movably connect the belt-sander to the first and second guide rails such that the belt-sander moves along the first and second guide rails and along the longitudinal axis of the elongated work piece;
and
the mounting bracket comprising a counterbalance member connected to the belt-sander and configured to counter the weight of the belt-sander in the first and second positions.
