Claim:
1. A suction cup device, comprising: a suction cup; a suction cup support shaft provided upright at a center position of a top face of the suction cup, the suction cup support shaft serving as a pull rod, the suction cup support shaft having a through hole toward one end, wherein the suction cup is attached to an attachment surface by applying a pulling force to the suction cup support shaft; an operation member extending longitudinally between a first end and a second end and being configured to move longitudinally in a first longitudinal direction and in a second longitudinal direction opposite the first longitudinal direction; a support pin extending through the through hole of the suction cup support shaft; and a housing within which are located the suction cup support shaft, the operation member, and the support pin, the housing being open at one face where a bottom face of said suction cup is exposed; and wherein the operation member has an insertion hole extending transversely through the operation member and spanning longitudinally along a partial length of the operation member, the suction cup support shaft extending through the insertion hole; wherein the operation member, at a portion bordering the insertion hole, defines an it dined face along said partial length with the support pin positioned on said inclined face and said support pin being configured to slide either one of up or down said inclined face as said operation member moves longitudinally, said inclined face extending from a latching recess portion encompassing a longitudinal center of said operation member toward said second end; wherein said operation member and support pin are configured so that movement of the operation member in the first longitudinal direction forces the support pin to move relatively up the inclined face thereby transmitting said pulling force to the suction cup support shaft and suction cup to pull said suction cup; wherein said operation member has a first position at a first farthest end of movement in said first longitudinal direction where said support pin is at a bottom end of said inclined face; wherein said operation member has a second position at a second farthest end of said movement in said second longitudinal direction where said support pin is at a second end of said inclined face having said latching recess portion; wherein the housing has a first opening and a second opening aligned along each one of said first longitudinal direction and second longitudinal direction and receives, respectively, said first end and second end of said operation member, said operation member being of a length approximating a distance between said first opening and second opening; wherein said inclined face is located along said operation member at a face position configured so when the operation member is at said second position said second end extends from said second opening by a second distance and said first end does not extend through said first opening; and wherein said fare position is further configured so when the operation member is at said first position said first end extends through said first opening by a first distance greater than said second distance and said second end is recessed relative to an outermost extent of said second opening by a third distance, said third distance being at least one-half longitudinal length from said first end of said inclined face to said bottom end.
