Hinge with stop

Claim 2

A hinge for pivotally connecting a first and second member about a pivot axis, comprising: a first hinge portion comprising a cylindrical segment having first and second opposing surfaces and a terminating edge, said first hinge portion being connected to said first member; a second hinge portion having a guide slot for receiving said cylindrical segment of said first hinge portion, said slot comprising a mouth portion, a throat portion having spaced opposing arcuate walls substantially conforming with respective ones of said first and second opposing surfaces of said cylindrical segment for receiving said cylindrical segment in sliding engagement, and an end portion, said second hinge portion being connected to said second member; and a lip extending outwardly from said mouth portion, said first member engaging said lip after a predetermined rotation of said first hinge portion with respect to said second hinge portion for providing a stop.

Claim 3

The hinge recited in claim 1 wherein said lip is flexible.

Claim 4

The hinge recited in claim 2 wherein said second member has a wall portion adjacent said lip wherein, when said first member is rotated to said lip, said lip bends until it engages said wall.

Claim 5

A hinge for pivotally connecting a first and second member about a pivot axis, comprising: a first hinge portion comprising a cylindrical segment having a concave surface on one side and a concentric convex surface of the opposite side, said concave and convex surfaces terminating at an edge, said first hinge portion being connected to said first member; a second hinge portion having a guide channel for receiving said cylindrical segment of said first hinge portion, said channel having a mouth portion, a throat portion comprising a first arcuate surface substantially conforming to said concave surface and a second spaced arcuate surface substantially conforming to said convex surface, said throat receiving said cylindrical segment in sliding engagement, and an end portion, said second hinge portion being connected to said second member; said cylindrical segment being rotatable in sliding engagement in said throat portion in a first direction until said edge of said first hinge portion contacts said end portion of said guide channel thereby providing a stop; and said mouth portion having an outwardly extending lip that engages said first member at approximately the rotational position said edge engages said end portion.

Claim 6

A hinge for pivotally connecting a first and second member about a pivot axis, comprising: a first hinge portion comprising a cylindrical segment having a concave surface on one side and a concentric convex surface of the opposite side, said concave and convex surfaces terminating at an edge, said first hinge portion being connected to said first member; a second hinge portion having a guide channel for receiving said cylindrical segment of said first hinge portion, said channel having a mouth portion, a throat portion comprising a first arcuate surface substantially conforming to said concave surface and a second spaced arcuate surface substantially conforming to said convex surface, said throat receiving said cylindrical segment in sliding engagement, and an end portion, said second hinge portion being connected to said second member; said cylindrical segment being rotatable in sliding engagement in said throat portion in a first direction until said edge of said first hinge portion contacts said end portion of said guide channel thereby providing a stop; and said mouth portion having an outwardly extending lip that engages said first member at approximately the rotational position said edge engages said end portion.

Claim 7

The hinge recited in claim 4 wherein said lip is flexible.

Claim 8

The hinge recited in claim 4 wherein said first member comprises a wall portion adjacent said lip.

Claim 9

In a top loading clothes washer, a hinge for pivotally connecting the downwardly extending lip of the lid of said washer within a recess in the cabinet top, comprising: a first hinge portion connected to said lip of said lid, said first hinge portion having a first section on the inside of said lip defining a concave cylindrical bearing surface and a second section on the outside of said lip defining a convex cylindrical bearing surface; and a second hinge portion connected within said recess of said cabinet top, said hinge portion having a guide slot for receiving said first hinge portion, said slot having a top entrance extending laterally thereacross and having a downwardly and forwardly extending throat with opposing spaced concentric bearing surfaces terminating at an end portion, said first hinge portion being engaged in said throat portion of said second hinge portion wherein, when said lid is opened upwardly from the front, said first hinge portion rotates about an axis at the center of said concentric bearing surfaces with said concave and convex surfaces of said first hinge portion respectively sliding along said concentric bearing surfaces until the edge of said lip of said lid contacts the terminating end portion of said throat thereby providing a hinge stop.

Claim 10

In a top loading clothes washer, a hinge for pivotally connecting the downwardly extending lip of the lid of said washer within a recess in the cabinet top, comprising: a first hinge portion connected to said lip of said lid, said first hinge portion having a first section on the inside of said lip defining a concave cylindrical bearing surface and a second section on the outside of said lip defining a convex cylindrical bearing surface; and a second hinge portion connected within said recess of said cabinet top, said hinge portion having a guide slot for receiving said first hinge portion, said slot having a top entrance extending laterally thereacross and having a downwardly and forwardly extending throat with opposing spaced concentric bearing surfaces terminating at an end portion, said first hinge portion being engaged in said throat portion of said second hinge portion wherein, when said lid is opened upwardly from the front, said first hinge portion rotates about an axis at the center of said concentric bearing surfaces with said concave and convex surfaces of said first hinge portion respectively sliding along said concentric bearing surfaces until the edge of said lip of said lid contacts the terminating end portion of said throat thereby providing a hinge stop.

Claim 11

The hinge recited in claim 7 wherein said second hinge portion has an upwardly extending lip and said lid contacts said second hinge portion lip at approximately the rotational orientation that said edge contacts said terminating end portion thereby distributing the strain applied to said hinge, said lid, and said cabinet top at said stop.

Claim 12

The hinge recited in claim 7 wherein said cabinet top has at least first and second apertures within said recess and said second hinge portion has a bottom locating pin inserting through said first aperture, said second hinge portion being secured to said cabinet top by a screw inserted up through said second aperture into said second hinge portion.

Claim 13

The hinge recited in claim 7 wherein said first hinge portion snaps into said guide slot of said second hinge portion wherein a force is required to engage and disengage said first hinge portion from said second hinge portion.

Claim 14

The hinge recited in claim 7 wherein said first hinge portion has blocks at the ends of said concave surface, said blocks being located at the sides of said second hinge portion for preventing said first hinge portion from sliding laterally with respect to said second hinge portion.
