Abstract
Abstract A clip for securing a first member to a second member includes a flange portion having an opening, an inserting portion, a pawl portion provided upon the inserting portion so as to be engageable with the flange portion and the second member, and a plurality of foldable coupling portions for connecting the inserting portion with the flange portion. The inserting portion is inserted through the first member in a first direction, then back downwardly into the opening of the flange portion and finally through the second member in a second direction, thereby securing the first member to the second member. When the inserting portion is inserted into the opening of the flange portion, the pawl portion engages the flange portion to retain the flange portion in engagement with the undersurface of the first member. When the inserting portion is further inserted through the second member, the pawl portion engages the second portion member so as to clamp the second member in cooperation with the flange portion. The coupling portions are folded as a result of the insertion of the inserting portion into the opening of the flange portion so as to clamp the first member in cooperation with the flange portion.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
399 words
A clip for clampingly supporting a first member, comprising: a flange portion having a first surface for engaging a first surface of a first member, having aperture means defined therein, to be supported upon said clip; aperture means defined within said flange portion and defining a longitudinal axis for said clip; axially collapsible, radially expansible, coupling means, fixedly secured at one end thereof to said first surface of said flange portion, for achieving two different states in order to support said first member upon said clip, a first one of said two different states being defined by said coupling means extending substantially axially in the direction of said longitudinal axis of said clip, and having a first axial extent, so as to be capable of insertion through said aperture means defined within said first member to be supported upon said clip, and a second one of said two different states being defined by said coupling means being axially collapsed with respect to said flange portion, and having a second axial extent which is less than said first axial extent, and being expanded radially outwardly so as to thereby engage a second surface of said first member to be supported upon said clip whereby said axially collapsible, radially expansible coupling means cooperate with said flange portion to clampingly support said first member therebetween; insertion means, fixedly secured at one end thereof to a second end of said axially collapsible, radially expansible coupling means, for axial movement in a predetermined direction through said aperture means of said flange portion so as to axially collapse and radially expand said axially collapsible, radially expansible coupling means from said first one of said two different states to said second one of said two different states; locking means fixedly disposed upon a second end of said insertion means for lockingly engaging a second surface of said flange portion so as to retain said axially collapsible, radially expansible coupling means in said second one of said two different states when said insertion means has been moved through said aperture means of said flange portion in said predetermined direction and to a first predetermined extent; and means provided upon said insertion means between said first and second ends thereof for engaging said flange portion so as to limit said axial movement of said insertion means in said predetermined direction through said aperture means of said flange portion.
Claim 2
Dependent Claim
399 words
A clip for clampingly supporting a first member, comprising: a flange portion having a first surface for engaging a first surface of a first member, having aperture means defined therein, to be supported upon said clip; aperture means defined within said flange portion and defining a longitudinal axis for said clip; axially collapsible, radially expansible, coupling means, fixedly secured at one end thereof to said first surface of said flange portion, for achieving two different states in order to support said first member upon said clip, a first one of said two different states being defined by said coupling means extending substantially axially in the direction of said longitudinal axis of said clip, and having a first axial extent, so as to be capable of insertion through said aperture means defined within said first member to be supported upon said clip, and a second one of said two different states being defined by said coupling means being axially collapsed with respect to said flange portion, and having a second axial extent which is less than said first axial extent, and being expanded radially outwardly so as to thereby engage a second surface of said first member to be supported upon said clip whereby said axially collapsible, radially expansible coupling means cooperate with said flange portion to clampingly support said first member therebetween; insertion means, fixedly secured at one end thereof to a second end of said axially collapsible, radially expansible coupling means, for axial movement in a predetermined direction through said aperture means of said flange portion so as to axially collapse and radially expand said axially collapsible, radially expansible coupling means from said first one of said two different states to said second one of said two different states; locking means fixedly disposed upon a second end of said insertion means for lockingly engaging a second surface of said flange portion so as to retain said axially collapsible, radially expansible coupling means in said second one of said two different states when said insertion means has been moved through said aperture means of said flange portion in said predetermined direction and to a first predetermined extent; and means provided upon said insertion means between said first and second ends thereof for engaging said flange portion so as to limit said axial movement of said insertion means in said predetermined direction through said aperture means of said flange portion.
Claim 3
Dependent Claim

A clip as set forth in claim 1, wherein: said flange portion, said coupling means, and said insertion means comprise a one-piece plastic molding.
Claim 4
Dependent Claim
62 words
A clip as set forth in claim 1, wherein: said second end of said coupling means comprises a head portion having a diametrical extent which is less than the diametrical extent of said aperture means defined within said first member so as to permit insertion of said coupling means, and said head portion thereof, through said aperture means of said first member.
Claim 5
Dependent Claim
38 words
A clip as set forth in claim 3, wherein: said coupling means comprises a pair of arms fixedly connected at said one end thereof to said flange portion and at said second end thereof to said head portion.
Claim 6
Dependent Claim
