Abstract
A power tool arrangement includes a frame having an outlet. A power tool is coupled to the frame and includes a movable working element configured to engage a work piece. A hose includes first and second opposite ends and a biasing device configured to bias the hose into a longitudinally compressed position. The first end is coupled to the outlet. The second end is coupled to the working element such that the second end follows the movement of the working element and the hose thereby moves between the longitudinally compressed position and a longitudinally expanded position.
Claims9
A power tool arrangement, comprising:
- a power tool including a working element configured to engage a work piece, wherein the working element is movable between a first position and a second position;
- a vacuum device;
- a hose including first and second opposite ends;
- and
- a biasing device configured to bias the hose into one of a longitudinally compressed position and a longitudinally expanded position, the first end fluidly coupled to the vacuum device, and the second end fluidly coupled to the vacuum device through the first end and connected to the working element such that the second end follows the working element, and the hose is configured to compress and expand substantially linearly as the working element moves between the first position and the second position, wherein the biasing device is operatively coupled to the hose and configured to bias the hose such that a biasing force is exerted on the working element sufficient to move the working element from the second position to the first position.
A power tool arrangement, comprising:
- a power tool including a working element configured to engage a work piece during movement of the working element in a straight line from a first position to a second position;
- a vacuum device;
- a hose including first and second opposite ends;
- and
- a biasing device configured to bias the hose toward a longitudinally compressed position, the first end fluidly coupled to the vacuum device, and the second end fluidly coupled to the vacuum device through the first end and connected to the working element such that the second end follows the working element as the working element selectively moves:
- away from the first end and the hose thereby undergoes longitudinal expansion;
- and
- toward the first end and the hose thereby undergoes longitudinal compression,
- wherein the biasing device is configured to produce a biasing force of a magnitude that can be overcome by an actuating force exerted on the working element such that the hose longitudinally expands in response to the actuating force and longitudinally retracts from a longitudinally expanded condition in response to an absence of the actuating force.
