Abstract:
A clamp device comprising:a base;a leg portion protruded from an undersurface of the base;an engaging protruding piece protruding from a tip end of the leg portion and the engaging protruding piece extending parallel to the undersurface of the base;a pressing wing portion extending laterally from the base;an engagement protrusion protruding from an undersurface of a remote end of the pressing wing portion, and the engagement protrusion being substantially hemispherical in shape;a clamp member protruding from a top surface of the base; andsaid leg portion being insertable into a hole formed in a board having a thickness corresponding to a gap spacing between the undersurface of the base and an opposed surface of the engaging protruding piece and the engaging protruding piece being inserted into a notch formed in a periphery of the hole in the board, and once the clamp device is received and sufficiently rotated, within the hole, with respect to the board, the hemispherical shaped engagement protrusion engages with a mating engagement hole formed in the board to prevent further rotation of the clamp device, a portion of the board around a perimeter of the hole being located between the undersurface of the base and the engaging protruding piece, and the undersurface of the remote end of the pressing wing portion abutting and pressing against a top surface of the board so that the hemispherical engagement protrusion is biased into engagement with the mating engagement hole in the board thereby facilitating fixing of the clamp device to the board.
