Abstract
Suction cups with non-circular peripheral edges are formed with peripheral edges which are of uniform thickness regardless of the radial distance of the peripheral edge from the center of the cup body.
Claims9
A suction cup having:
- a) a substantially disc-shaped body defined by a relatively convex outer surface and a relatively concave inner surface joined at the lateral periphery of the body to define a non-circular peripheral edge wherein the thickness of said body at said non-circular edge is substantially constant along the entire periphery of said body;
- and
- (b) a mounting device substantially centrally located and extending from said convex outer surface;
- wherein said cup body defines a nominal center having a first thickness which is greater than the thickness of said body at said non-circular edge and the distance from said outer surface to said inner surface decreases at a relatively uniform rate along the radial distance from said nominal center to said non-circular edge.
A suction cup having a body formed of relatively soft, pliable material which is defined by:
- (a) a central portion having a first thickness;
- (b) an outer surface;
- (c) an inner surface which joins said outer surface to define a peripheral edge of non-circular geometry wherein the thickness of said peripheral edge is relatively constant regardless of the radial distance of said peripheral edge from said central portion;
- and
- (d) a mounting device extending from said central portion of said outer surface;
- wherein said first thickness is greater than said thickness of said peripheral edge and the thickness of said body decreases from said central portion to said peripheral edge at a relatively constant rate regardless of the distance of said peripheral edge from said central portion.
A suction cup having a substantially disc-shaped body defined by a relatively convex outer surface and a relatively concave inner surface joined at the lateral periphery of the body to define a non-circular peripheral edge wherein:
- (a) the thickness of said body at said non-circular edge is substantially constant along the entire periphery of said body;
- (b) said cup body defines a nominal center having a first thickness which is greater than the thickness of said body at said non-circular edge;
- and
- (c) the distance from said outer surface to said inner surface decreases at a relatively uniform rate along the radial distance from said nominal center to said non-circular edge.
A suction cup having a body formed of relatively soft, pliable material which is defined by:
- (a) a central portion having a first thickness;
- (b) an outer surface;
- and
- (c) an inner surface which joins said outer surface to define a peripheral edge of non-circular geometry wherein the thickness of said peripheral edge is less than said first thickness and is relatively constant regardless of the radial distance of said peripheral edge from said central portion;
- wherein the thickness of said body decreases from said central portion to said peripheral edge at a relatively constant rate regardless of the distance of said peripheral edge from said central portion.
