摘要:
An object sensor for sensing objects hidden from view behind a first wall surface. The object sensor (10) has a housing having a front surface (17) with a display (24) and a rear surface (21). The object sensor also has a sensing system (12) and provides additional functions. The additional functions can include a distance detector, a computing system working in conjunction with the distance detector to determine the distance between the object sensor and a second wall, a tracking mechanism, and a projector to project a beam at predetermined distances. The object sensor may further have a level or a location marker.

A tool safety system minimizes the likelihood of injury by detecting when a body part is in close proximity to a moving part of the tool. Upon detecting, a control system can provide one or more of moving the tool, disabling the moving part, or producing a warning signal.

A surface planer (10) for planing wooden boards (12) is provided having a motor (24) and an associated rotary cutter head (26) operatively driven thereby and a feed roller (30) positioned adjacent the rotary cutter head for moving wooden boards relative to the cutter. The surface planer has a first gearbox (32) and a second gearbox (62), the second gearbox being provided with a speed selector element (70) for selectively the rotational speed of the feed roller (30).
摘要:
An ergonomic miter saw is provided having a base (12) and a saw arm assembly (16) with the saw arm assembly pivotally affixed at a fixed end to the base and provided with a distal end having a handle extending outwardly therefrom. The central region of the arm assembly includes a rotary spindle supporting a cutting disk (28). A handle (20) is preferably provided with an elongate grip portion sized for the user's fingers and a palm pad portion (46) extending outwardly therefrom to underlie the heal of the user's hand to minimize bending torque on the user's wrist as the arm is lowered. Ideally, the handle is rotated in a direction opposite that the cutting disk is tilted. Preferably, the handle is adjustably oriented about the arm axis in a direction opposite that the saw blade is tiltable so that the deviation for horizontal of the handle can be minimized when the miter saw is used in a tilted cutting disk mode.

A surface planer (10) for planing a wooden board (12) comprising a motor (24) having a rotationally driven motor output member turning at a first rotational speed; a rotary cutter head (26) operatively connected to and rotationally driven by the motor output member; a pair of feed rollers (28,30) longitudinally spaced about the rotary cutter head; a frame (14) including at least two laterally spaced apart columns (18) on opposite lateral sides of the board to be planed which is adjustably positionable by the operator at a selected distance from the cutter head in order to achieve a selected board thickness; and a multi-stage transmission having an input connected to the motor (24) and an output drivably connected to at least one of the feed rollers, the multi-stage transmission including a dual speed stage provided with an operator actuated speed selected element (70) which when shifted by the operator, changes the final drive ratio and the resulting speed that the feed rollers move the wooden board relative to the cutter head.
