Abstract
Abstract The embodiment of the invention disclosed herein is directed to a door handle anchor which can be placed behind the panel of a sheet metal door and has prongs formed thereon to extend through an aperture formed in the door. A threaded fastener is inserted between the prongs and threaded into a bore in alignment therewith. The prongs are urged outwardly to prevent pushing the anchor back through the aperture during threading of the fastener. The anchor is formed of a molded plastic component having an integral arm extending a distance sufficient to engage a sidewall formed by turned edge of the door receiving the same.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
243 words
A door handle anchor for receiving a threaded fastener having predetermined pitch and major diameters to mount a handle thereto, comprising in combination; a body having a bore formed therein to receive a threaded fastener, said bore having a diameter equal to or less than said pitch diameter whereby rotative introduction of said fastener results in threads being formed in said body, a flange formed on said body transverse to the axis of said bore to overlie the periphery of an aperture formed in a door panel of relatively thin material, said aperture being located a predetermined distance from a turned edge of said door panel, prong means formed integrally with said body and extending therefrom parallel to the axis of said bore and adapted for insertion into said aperture partially to extend through said panel, said prong means being sufficiently spaced apart so as to define an opening therebetween to freely receive the major diameter of the threaded end of said threaded fastener when in its initial condition and having a diameter an interconnecting section between said opening and said bore greater than said bore diameter, and an elongated arm portion formed integrally with said body and extending from said opening a distance greater than said predetermined distance, whereby said anchor will have the elongated arm portion thereof engaging said turned edge during tightening of said threaded fastener for holding the same in place while mounting the handle to the door panel.
Claim 2
Dependent Claim
243 words
A door handle anchor for receiving a threaded fastener having predetermined pitch and major diameters to mount a handle thereto, comprising in combination; a body having a bore formed therein to receive a threaded fastener, said bore having a diameter equal to or less than said pitch diameter whereby rotative introduction of said fastener results in threads being formed in said body, a flange formed on said body transverse to the axis of said bore to overlie the periphery of an aperture formed in a door panel of relatively thin material, said aperture being located a predetermined distance from a turned edge of said door panel, prong means formed integrally with said body and extending therefrom parallel to the axis of said bore and adapted for insertion into said aperture partially to extend through said panel, said prong means being sufficiently spaced apart so as to define an opening therebetween to freely receive the major diameter of the threaded end of said threaded fastener when in its initial condition and having a diameter an interconnecting section between said opening and said bore greater than said bore diameter, and an elongated arm portion formed integrally with said body and extending from said opening a distance greater than said predetermined distance, whereby said anchor will have the elongated arm portion thereof engaging said turned edge during tightening of said threaded fastener for holding the same in place while mounting the handle to the door panel.
Claim 3
Dependent Claim
50 words
The door handle anchor for receiving a threaded fastener to mount a door handle as set forth in claim 1 wherein a recess is formed about the periphery of said prong means to form a retaining edge for the periphery of said aperture to hold said anchor rotatably in place.
Claim 4
Dependent Claim
33 words
The door handle anchor for receiving a threaded fastener to mount a handle as set forth in claim 2 further including a resilient sealing ring positioned about said prong means engaging said recess.
Claim 5
Dependent Claim
45 words
The door handle anchor for receiving a threaded fastener to mount a door handle as set forth in claim 1 wherein said body is formed of rigid rib sections extending from said flange in quadrature, said arm portion being an extended one of said ribs.
Claim 6
Dependent Claim
35 words
The door handle anchor for receiving a threaded fastener to mount a door handle as set forth in claim 4 wherein the terminating end of said rib portion forming said arm portion is circular configuration.
Claim 7
Dependent Claim
68 words
The door handle anchor for receiving a threaded fastener to mount a door handle as set forth in claim 1 wherein said prong means is formed of spaced-apart portions having a split formed therein with the diverging outward walls leading from said opening, said diverging outward walls having the ends thereof spaced apart sufficient to freely receive the major diameter of the terminating end of the threaded fastener.
Claim 8
Dependent Claim
65 words
A door handle anchor of the type as set forth in claim 1, wherein said body includes means at the end of said bore opposite said prongs and defining an aperture substantially smaller in size than the diameter of said bore to accept the tapered end of said fastener, when inserted therethrough, in intimate sealing relation and thereby providing a prevailing torque on said fastener.
