Patent ID: 7270357

Claim:
An adjustable suction device comprising: first and second suction cups, each comprising a cup body mounted to an underside of a support disk, a mounting block rotatably fixed to a top side of the support disk to be rotatable about a first axis with respect to the support disk, a pivot mounted on the support disk and defines a second axis; a controlling mechanism arranged and coupled between the first and second suction cups, the controlling mechanism comprising a main body defining a channel therethrough, a rack movably received in the channel, an end of the main body being rotatably mounted to the second suction cup via the pivot of the second suction cup so as to allow the second cup to rotate about the pivot with respect to the main body, an end of the rack forming a threaded section engaging an inner-threaded cylinder whereby rotation of the cylinder causes the cylinder to axially move along the threaded section of the rack whereby the cylinder is moved with respect to the main body, the cylinder being rotatably mounted to the first suction cup through the pivot of the first suction cup so as to allow the first suction cup to rotate about the second axis with respect to the main body; the controlling mechanism further comprising a manually operated pinion that drivingly engages the rack whereby manual operation of the pinion drives the rack and inducing translation of the first suction cup with respect to the second suction cup.
