US 5,347,902 A · Motorized miter box

Abstract

A motorized miter box or saw comprising a cuttinghead handle for guiding the movement of the saw between a raised, rest position and a lowered, operational position. The cuttinghead handle is adjustably coupled to the cuttinghead so that the orientation of the cuttinghead handle with respect to a user of the saw can be adjusted by the user between a first position and a second position. The first position has a preferred orientation for the user when the saw is located on a floor or at a similar elevation and the user is kneeling or similarly located at floor level. The second position has a preferred orientation for the user when the saw is located on a bench or similar elevated structure and the user is standing or similarly located in front of the saw. The disclosed motorized miter box also comprises a carrying handle for use by a user in carrying the miter box between work sites. The carrying handle protrudes from the rear of the miter box base. The carrying handle comprises a support surface located in the same geometric plane as the lower surface of the base so that the carrying handle helps prevent the miter box saw from tipping backwards if the cuttinghead apparatus is allowed to move freely from its lowered, operational position to its upper, at rest position.

Dependent claims

A motorized miter box, comprising:

(a) a base;
(b) a turntable rotatably supported by the base;
(c) a fence disposed above the base for supporting the orientation of a workpiece located at the base;
(d) a support coupled to the turntable at a rear portion of the turntable;
(e) cuttinghead means comprising a motor driving a saw blade for cutting the workpiece, the cuttinghead means being pivotally coupled to the support for positioning the saw blade between a raised, rest position and a lowered, operational position;
(f) cuttinghead handle means comprising a cuttinghead handle having a switch electrically coupled to the motor, the cuttinghead handle being configured for guiding the movement of the saw blade between the raised, rest position and the lowered, operational position, the cuttinghead handle means comprising adjustable coupling means for adjustably coupling the cuttinghead handle to the housing of the cuttinghead means so that the orientation of the cuttinghead handle with respect to a user of the motorized miter box can be selectively adjusted by the user over a range of positions between a first position and a second position.
