Abstract: A wearable kneel-sit support device includes a U-shaped body that is pivotally connected to both a seat member and a base member. A linking member connects the seat member and the base member, such that moving one of the seat member and the base member causes both the seat member and the base member to rotate from a folded position adjacent the leg of the user to an unfolded position. In the unfolded position, the base member can rest on a horizontal surface and the seat member is substantially parallel to the base member, so that the wearer can sit on the seat while kneeling. The device may be worn on the lower leg of a user in a folded position to allow unhindered ambulation.

Abstract: For improved removal of dust generated in sanding with a rotating disk sander, while simutaneously maintaining a sanding surface thereof free of clogging by dust particles, there is provided a plurality of compressed gas nozzles distributed lengthwise along an elongated common compressed gas supply manifold. The nozzles preferable are disposed to deliver high velocity jets of a compressed gas into a rotating boundary layer at the rotating sanding disk surface to thereby interact with the boundary layer and to simultaneously forcibly dislodge any dust particles tending to adhere to the air sanding disk surface. Suction is provided around a portion of the sanding disk to remove the dust particles that are entrained in the boundary layer and any dust particles dislodged from the sanding disk surface. In one aspect of this invention, the apparatus thereof may be added to a conventional disk sander apparatus to improve dust collection therefrom.

Abstract: A dust collecting assembly for use with a machine tool having a rotating tool bit, which includes means for applying a plurality of parallel jets of air in the direction of particles as they are removed from a workpiece by the tooling operation. The jets of air are directed to slow down the particles so that they may be removed by a vacuum exhaust system. In applying the method to multi-directional tooling operations a plurality of jets surround the entire work area and selected subgroups of the jets are activated which oppose the trajectory of removed particles as the direction of the tooling operation changes.

Abstract: An ergonomic tool handle (21) which is useful for a terminal insertion hand tool, gardening hand tools, knives, box cutters, screwdrivers and other pushing or pulling type hand tools. The tool handle (21) of the present invention is contoured to promote neutral posture between the hand and wrist as well as complementing the shape of the closed hand to distribute longitudinal tool forces evenly throughout the hand and arm of the user. The tool handle (21) accomplishes this neutral posture and contoured fit by featuring a humplike crown (28) which fits snugly into the pocket of the palm, a relatively flat underside (29) around which the user's finger tips (55-57) are wrapped and two sides (51, 52) with convex regions (30, 31) in diagonally offset relation. By moving one's hand up or down the tool handle (21), one size of tool handle (21) can ergonomically fit approximately 95% of male and female hand sizes.
