Abstract
Abstract A support for mounting plastic components on an apertured panel comprising a base for resiliently bearing a component integral therewith on the panel, a stem extending from the base through the aperture, diverging yieldable wings on the free end of the stem, and extensions on each wing having shoulders adapted to seat against the sides of the aperture and the undersurface of the panel.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
163 words
In a support integral with a component and a panel having a circular aperture therein for mounting the component on one face of the panel, said support comprising a resilient substantially elongated base connected to the component and having opposed free ends arched in the direction of the panel, a stem extending centrally from the base and through the aperture, a pair of yieldable wings integral with and extending from the free end of said stem toward said panel, said wings having diverging free ends one aligned with each of said base ends and normally spread beyond the perimeter of said circular aperture, an extension on the free end of each wing adapted to enter the aperture when the support is mounted, said extensions and said wing ends being contoured to bear against the perimeter of said aperture and said panel to prevent spreading of said wings and to center said support in the aperture when the support is mounted on the panel.
Claim 2
Dependent Claim
163 words
In a support integral with a component and a panel having a circular aperture therein for mounting the component on one face of the panel, said support comprising a resilient substantially elongated base connected to the component and having opposed free ends arched in the direction of the panel, a stem extending centrally from the base and through the aperture, a pair of yieldable wings integral with and extending from the free end of said stem toward said panel, said wings having diverging free ends one aligned with each of said base ends and normally spread beyond the perimeter of said circular aperture, an extension on the free end of each wing adapted to enter the aperture when the support is mounted, said extensions and said wing ends being contoured to bear against the perimeter of said aperture and said panel to prevent spreading of said wings and to center said support in the aperture when the support is mounted on the panel.
Claim 3
Dependent Claim
26 words
The support recited in claim 1, wherein the base comprises a flexible substantially rectangular member having its opposed ends arched in the direction of the panel.
Claim 4
Dependent Claim
24 words
The support recited in claim 2, wherein a web connects the base and component and is weakened to increase flexibility of the base member.
Claim 5
Dependent Claim
26 words
The support recited in claim 1, wherein the stem is of sufficient width in one direction to substantially bridge the aperture to prevent its shifting laterally.
Claim 6
Dependent Claim
18 words
The support recited in claim 1, wherein the support and component are molded from plastic dielectric insulating material.
Claim 7
Dependent Claim
18 words
The support recited in claim 1, wherein said extension is substantially parallel to the walls of said aperture.
Claim 8
Dependent Claim
21 words
The support recited in claim 4, wherein the wings are disposed in a plane angular to the width of the stem.
