Abstract
Abstract The present invention relates generally to spring type fastener clips, and more particularly to improvements in fastener clips of the type adapted to accommodate the margins of panels. The embodiment disclosed herein includes a sheet metal stamping presenting an elongate relatively narrow base section and laterally yieldable converging panel engaging wing members extending from opposite longitudinal margins of said base section. The opposite extremities of the outer marginal edges of said wing members diminish in distance from the base section to facilitate initial reception of a panel margin, and integral struck-out panel attachment prongs extend from the base section in a direction opposite to the wing members.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
103 words
A fastener clip for attachment to a panel margin including an elongate relatively narrow base section, normally converging laterally yieldable panel-engaging wing members extending from opposite longitudinal margins of said base secTion, the outer edges of said wing members from a location intermediate the extremities thereof diminishing in distance from said base section to an area immediately adjacent the opposite extremities of said base section to facilitate initial reception of a panel margin between said wing members in the vicinity of said base section, and integral spaced panel attachment means extending from the base section in a direction opposite to said wing members.
Claim 2
Dependent Claim
103 words
A fastener clip for attachment to a panel margin including an elongate relatively narrow base section, normally converging laterally yieldable panel-engaging wing members extending from opposite longitudinal margins of said base secTion, the outer edges of said wing members from a location intermediate the extremities thereof diminishing in distance from said base section to an area immediately adjacent the opposite extremities of said base section to facilitate initial reception of a panel margin between said wing members in the vicinity of said base section, and integral spaced panel attachment means extending from the base section in a direction opposite to said wing members.
Claim 3
Dependent Claim
45 words
A fastener clip for attachment to a panel margin as set forth in claim 1, wherein the outer edges of the wing members progressively diminish in distance from a central intermediate location of said base to opposite points in the vicinity of said base extremities.
Claim 4
Dependent Claim
38 words
A fastener clip for attachment to a panel margin as set forth in claim 2, wherein the outer edges diminishing in distance from the base define a curve, the opposite extremities of which terminate adjacent the base extremities.
Claim 5
Dependent Claim
27 words
A fastener clip for attachment to a panel margin as set forth in claim 1, wherein the integral attachment means comprise prongs struck from the fastener base.
Claim 6
Dependent Claim
26 words
A fastener clip for attachment to a panel margin as set forth in claim 4, wherein said struck-out prongs are generally arcuate in transverse cross section.
Claim 7
Dependent Claim
29 words
A fastener clip for attachment to a panel margin as set forth in claim 4, wherein the struck-out prongs present pairs of work engaging faces facing toward each other.
Claim 8
Dependent Claim
120 words
A one-piece sheet metal fastener clip for attachment to a panel margin including an elongate relatively narrow base section, normally converging laterally yieldable panel engaging wing members extending from opposite longitudinal margins of said base section, said wing members comprising flat sheet metal sections, the outer edges of which define a curve extending from a point adjacent one extremity of said base to a point adjacent the opposite extremity to said base section whereby to facilitate initial reception of a panel margin between said wing members in the vicinity of said base section, and integral spaced panel attachment means in the form of members struck from the base section and extending therefrom in a direction opposite to said wing members.
Claim 9
Dependent Claim
120 words
A one-piece sheet metal fastener clip for attachment to a panel margin including an elongate relatively narrow base section, normally converging laterally yieldable panel engaging wing members extending from opposite longitudinal margins of said base section, said wing members comprising flat sheet metal sections, the outer edges of which define a curve extending from a point adjacent one extremity of said base to a point adjacent the opposite extremity to said base section whereby to facilitate initial reception of a panel margin between said wing members in the vicinity of said base section, and integral spaced panel attachment means in the form of members struck from the base section and extending therefrom in a direction opposite to said wing members.
