Releasable suction cup assembly

Claim 2

A suction cup assembly comprising: a base; a suction cup of flexible composition secured onto said base; and, a strap having a first end portion secured to said suction cup and a second end portion secured to said base.

Claim 3

A suction cup assembly as defined in claim 1 in which said suction cup has a lip and said strap is secured to said cup in the vicinity of said lip and said strap when tensioned is effective to deflect said lip.

Claim 4

A suction cup assembly as defined in claim 1 in which said strap when tensioned is effective to impose a local withdrawal force on the sidewall of said suction cup, said withdrawal force being directed generally normal to the plane of a host surface.

Claim 5

A suction cup assembly as defined in claim 1 in which said strap has leg portions defining a partial fold intermediate said end portions.

Claim 6

A suction cup assembly as defined in claim 4 in which said partial fold defines an "S" configuration.

Claim 7

A suction cup assembly as defined in claim 1 in which said strap includes first and second leg portions intermediate said end portions, said leg portions being folded about a knee, said knee projecting laterally relative to said suction cup.

Claim 8

A suction cup assembly as defined in claim 6 in which said knee projects inwardly toward said suction cup.

Claim 9

A suction cup assembly as defined in claim 6 in which said knee projects outwardly away from said suction cup.

Claim 10

In combination: a suction cup assembly including a suction cup of flexible composition and adapted for unassisted vacuum hold onto a recipient host surface to which the suction cup is to be attached,and an anchor button attached to said cup; a release strap attached to said suction cup and effective when tensioned to dissipate the force of the vacuum hold for enabling removal of said suction cup from the host surface, said release strap having a freely movable end portion and an anchor button attached to said freely movable end portion; and, an article to be supported by said suction cup assembly, said article having first and second perforations through which said suction cup anchor button and said release strap anchor button are inserted, respectively, said suction cup anchor button retaining said suction cup against said article to be supported, and said release strap anchor button engaging said article to be supported and retaining said release strap against said article to be supported as said article to be supported is pulled away from the recipient host surface.

Claim 11

In combination: a suction cup assembly including a suction cup of flexible composition and adapted for unassisted vacuum hold onto a recipient host surface to which the suction cup is to be attached,and an anchor button attached to said cup; a release strap attached to said suction cup and effective when tensioned to dissipate the force of the vacuum hold for enabling removal of said suction cup from the host surface, said release strap having a freely movable end portion and an anchor button attached to said freely movable end portion; and, an article to be supported by said suction cup assembly, said article having first and second perforations through which said suction cup anchor button and said release strap anchor button are inserted, respectively, said suction cup anchor button retaining said suction cup against said article to be supported, and said release strap anchor button engaging said article to be supported and retaining said release strap against said article to be supported as said article to be supported is pulled away from the recipient host surface.

Claim 12

The combination as defined in claim 9, wherein the recipient host surface is an automobile windshield, and the article to be supported is a sun shield.

Claim 13

A suction cup assembly comprising: a base; a suction cup of flexible composition secured onto said base; an anchor button; and, an arm attached to said anchor button and to said suction cup.

Claim 14

A suction cup assembly comprising: a base; a suction cup of flexible composition secured onto said base; an anchor button; and, an arm attached to said anchor button and to said suction cup.

Claim 15

A suction cup assembly as defined in claim 11, said arm being a flexible strap extending from said suction cup and having a freely movable end portion; and, said anchor button being attached to said freely movable end portion of said flexible strap.

Claim 16

A suction cup assembly as defined in claim 11, including an anchor button secured to said base.

Claim 17

A releasable suction cup assembly comprising, in combination: a suction cup having a flexible sidewall adapted for suction engagement against a host surface; and, a release strap attached to said flexible sidewall, said release strap being adapted for attachment to an article to be supported adjacent to the host surface and operable to deflect said sidewall away from the host surface in response to displacement of said article relative to the host surface.

Claim 18

A releasable suction cup assembly comprising, in combination: a suction cup having a flexible sidewall adapted for suction engagement against a host surface; and, a release strap attached to said flexible sidewall, said release strap being adapted for attachment to an article to be supported adjacent to the host surface and operable to deflect said sidewall away from the host surface in response to displacement of said article relative to the host surface.
