Abstract:
A clamping device for combined floors, the combined floors each having a rectangular body, a protrusion longitudinally and laterally extending from a first side of the body and a connecting groove longitudinally and laterally defined in a second side of the body, wherein the first side and the second side of the body are opposite to each other, a first groove longitudinally and laterally defined in the first side of the body under the protrusion, a second groove longitudinally and laterally defined in the second side of the body under the connecting groove, wherein the first groove and the second groove correspond to each other, a third groove and a fourth groove longitudinally defined in a bottom of the body and parallel to each other, the clamping device connected to an adjacent clamping device and comprising:a base member including: a snapper extending upwardly from the base member, the snapper having an enlarged head formed on a free end of the snapper and adapted to be received in the first groove of the combined floor and the second groove of the an adjacent combined floor; a first rib upwardly extending from the base member near a first side of the base member; a second rib upwardly extending from the base member near a second side of the base member; a &pgr;-shaped bracket laterally extending from the first side of the base member, the &pgr;-shaped bracket having two bridges parallel to each other and connected to the base member, and a top plate integrally connected to the two bridges of the &pgr;-shaped bracket and parallel to the first side of the base member, the top plate of the &pgr;-shaped bracket including two opposite ends each having a stub perpendicularly extending from the top plate and directing to the first side of the base member, each bridge of &pgr;-shaped bracket having a wing plate laterally extending to connect to a corresponding one of the stub; a recess defined in the base member for movably receiving the top plate of the &pgr;-shaped bracket of an adjacent clamping device; a channel centrally defined in a second side of the base member, the channel extending to communicate with the recess and movably receiving the two bridges of the &pgr;-shaped bracket of the adjacent clamping device, the channel having a width narrower than that of the recess so that two blocks formed on two opposite ends of the second side of the base member; a bore defined in each block to receive a spring in the block and extends to communicate with the recess; a passage laterally defined in each block, the passage extending to communicate with the channel and the bore for slidably receiving the wing plate of the &pgr;-shaped bracket of the adjacent clamping device when the clamping devices are connected; and a cutout defined in each block and communicating with the passage for forming a guiding portion to guide the wing plate into the passage.
