A device for attachment to both porous and non-porous wall surfaces includes a suction cup having an elastomeric core and an elastomeric outer layer that is substantially softer than the inner layer. The outer layer includes material that fills pores within a porous surface against which the suction cup is held. The inner layer prevents tearing of the suction cup and causes a partial vacuum to be formed as the suction cup attempts to return to its original shape following depression against a wall surface.
1. Apparatus comprising: a housing;a suction cup attached to the housing, wherein the suction cup includes a core composed of a first elastomer and an annular outer layer composed of a second elastomer, substantially softer than the first elastomer, wherein the core forms a central portion of the suction cup, an annular peripheral portion of the suction cup, and a disk-shaped portion of the suction cup, having a concave outward-facing surface extending radially from the central portion to the annular peripheral portion, and wherein the outer layer covers...
