Molded latchable hinge

Claim 2

A clip comprising a body section, a hook section extending outwardly from a first end of said body section and defining a slot and having a first selected transverse dimension, and a latch arm extending from a second end of said body section toward said hook section to a free end proximate said slot and having a second selected transverse dimension less than said first selected transverse dimension, said latch arm being deflectable toward said body section; and said slot having an arcuate inner surface extending about a circle angularly at least about 160° whereby an angular opening extends about the remaining portion of said circle, and said latch arm defining a surface substantially filling said angular opening, said hook section having two portions spaced from each other a distance greater than said second transverse dimension and extending from said body section at opposed sides thereof to a common free end section extending transversely between said spaced hook portions, together defining an enclosed opening opposed from said latch arm free end whereby said latch arm is deflectable toward said body section during insertion of a transversely disposed cylindrical article into said slot through said opening and upon complete insertion said cylindrical article is held within said slot by said latch arm free end upon resiling of said latch arm, and whereby a relief region between said latch arm and said body section is easily moldable by providing access for a mold core pin extending thereinto from a direction opposite said opening and enabling said body section, said hook portions and said latch arm to be easily molded in an integral article.

Claim 3

The clip as set forth in claim 1 wherein said hook section defines a slot having an arcuate inner surface extending about a circle angularly about 180°.

Claim 4

A hinged article comprising a first section and a second section pivotably attached to said first section along a hinge axis defined by aligned slots of at least a pair of spaced apart hook sections along an edge of a wall of said first article, said first section including at least a pair of spaced apart latch arms joined to said wall at locations spaced from said pair of hook sections and extending toward openings of said slots thereof to free ends substantially filling said openings when said latch arms are undeflected, whereby corresponding dowel means of said second section are insertable into said hook sections upon deflection of said latch arms toward said wall and retained thereafter within said slots by said spaced apart latch arm free ends in a manner permitting removal therefrom if desired, and said second section is pivotable thereafter about said dowel means disposed along said hinge axis, each said hook section extending transversely a first selected dimension and each said latch arm having a transverse width extending a second selected dimension, each said hook section defining a slot having an arcuate inner surface extending about a circle angularly at least about 160° whereby an angular opening extends about the remaining portion of said circle, and each said latch arm defining a surface substantially filling a respective said angular opening, said second selected transverse dimension being less than said first selected transverse dimension, and each said hook section comprising two portions spaced from each other a distance greater than said second transverse dimension and extending from said wall at two transversely spaced locations to a common free end section extending transversely between said spaced hook portions, defining an enclosed opening opposed from said latch arm free end, whereby a relief region between each said latch arm and said wall is easily moldable by providing access for a mold core pin extending thereinto from a direction opposite said opening and enabling said first section, said hook portions and said latch arms to be easily molded in an integral member.

Claim 5

A hinged article comprising a first section and a second section pivotably attached to said first section along a hinge axis defined by aligned slots of at least a pair of spaced apart hook sections along an edge of a wall of said first article, said first section including at least a pair of spaced apart latch arms joined to said wall at locations spaced from said pair of hook sections and extending toward openings of said slots thereof to free ends substantially filling said openings when said latch arms are undeflected, whereby corresponding dowel means of said second section are insertable into said hook sections upon deflection of said latch arms toward said wall and retained thereafter within said slots by said spaced apart latch arm free ends in a manner permitting removal therefrom if desired, and said second section is pivotable thereafter about said dowel means disposed along said hinge axis, each said hook section extending transversely a first selected dimension and each said latch arm having a transverse width extending a second selected dimension, each said hook section defining a slot having an arcuate inner surface extending about a circle angularly at least about 160° whereby an angular opening extends about the remaining portion of said circle, and each said latch arm defining a surface substantially filling a respective said angular opening, said second selected transverse dimension being less than said first selected transverse dimension, and each said hook section comprising two portions spaced from each other a distance greater than said second transverse dimension and extending from said wall at two transversely spaced locations to a common free end section extending transversely between said spaced hook portions, defining an enclosed opening opposed from said latch arm free end, whereby a relief region between each said latch arm and said wall is easily moldable by providing access for a mold core pin extending thereinto from a direction opposite said opening and enabling said first section, said hook portions and said latch arms to be easily molded in an integral member.

Claim 6

The hinged article as set froth in claim 3 wherein each said hook section defines a slot having an arcuate inner surface extending about a circle angularly about 180°.
