초록

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 at least an outward-facing surface of the annular peripheral portion; anda wall having a porous surface held against at least a portion of the outer layer of the suction cup with material from the outer layer disposed within pores of the porous surface. 2. The apparatus of claim 1, wherein the outer layer additionally covers surfaces of the disk-shaped portion and of the central portion. 3. The apparatus of claim 1, wherein the second elastomer has a hardness in the range of Shore A 10 to Shore A 20. 4. The apparatus of claim 3, wherein the first elastomer has a hardness in the range of Shore A 50 to Shore A 70. 5. The apparatus of claim 3, wherein the outer layer has a thickness in the range of 0.8 mm to 1.8 mm. 6. The apparatus of claim 1, wherein the second elastomer is selected from a group comprising thermoplastic elastomers, silicone rubbers, and urethane elastomers. 7. The apparatus of claim 6, wherein the first elastomer is selected from a group comprising thermoplastic elastomers, silicone rubbers, and urethane elastomers. 8. The apparatus of claim 1, wherein the central portion of the core is attached to the housing, and wherein the peripheral portion of the core is inwardly deflectable. 9. The apparatus of claim 1, additionally comprising an actuator, wherein the central portion of the core is attached to the housing by the actuator,the actuator is mounted on the housing to be moved between a released position and an actuated position,the actuator moves the central portion of the core inward within the housing as the actuator is moved from the released position to the actuated position, andthe housing includes a peripheral ring preventing movement of the peripheral portion of the core as the actuator is moved from the released position to the actuated position, increasing a volume of a space between a surface to which the apparatus is being attached and the suction cup to form a partial vacuum within the space to hold the apparatus in place on the surface to which the apparatus is being attached. 10. A suction cup comprising a core composed of a first elastomer and an 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, wherein the outer layer covers outward-facing and inward-facing surfaces of the core, and wherein the outer layer covers substantially all external surfaces of the core. 11. The suction cup of claim 10, wherein the second elastomer has a hardness in the range of Shore A 10 to Shore A 20. 12. The suction cup of claim 11, wherein the first elastomer has a hardness in the range of Shore A 50 to Shore A 70. 13. The suction cup of claim 11, wherein the outer layer has a thickness in the range of 0.8 mm to 1.8 mm. 14. The suction cup of claim 10, wherein the second elastomer is selected from a group comprising thermoplastic elastomers, silicone rubbers, and urethane elastomers. 15. The suction cup of claim 14, wherein the first elastomer is selected from a group comprising thermoplastic elastomers, silicone rubbers, and urethane elastomers.
