Abstract
Abstract A mailbox support is disclosed including a base bracket engageable with a vertical post support means, a pivot pin on the base bracket extending through apertures in the inner ends of first and second base arms, a coil spring surrounds the base pivot pin to increase frictional resistance to pivotal movement of the base arms with respect to the base bracket with outer arms being pivotally connected by an arm pivot pin to the outer ends of the base arms; a mailbox supporting bracket is pivotally connected to the outer ends of the outer arms with coil springs increasing the frictional resistance to pivotal movement of the components so that a mailbox mounted on the mailbox supporting bracket can be positioned outwardly at a desired point and can also be positioned at a desired vertical height at any desired outward point from the supporting post and will remain in position unless additional force is applied to the mailbox.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
267 words
Attachment means for enabling the adjustable attachment of a mailbox or the like to a vertical support post, said attachment means comprising base bracket means connectable with said post, base pivot means mounted on said base bracket means, elongated base arm means comprising first and second parallel tubular arm members having flattened end surfaces pivotally connected on an inner end to said base bracket means by said base pivot means for pivotal movement with respect to said base bracket, arm pivot means mounted on an outer end portion of said base arm means spaced from the pivotal connection of said base arm means to said base pivot means, outer arm means pivotally connected on one end to said arm pivot means, a connecting bracket including means enabling connection to a mailbox or the like, a connecting bracket pivot means on the end of said outer arm means spaced from the pivotal connection of said outer arm means to said arm pivot means, said connecting bracket being pivotally connected to said connecting bracket pivot means and friction increasing means associated with the pivotal connection between said base arm means and said base bracket means and the pivotal connection between the outer end of said base arm means and the end of the outer arm means pivotally connected thereto and the outer end of the outer arms and the connecting bracket whereby the frictional resistance to pivotal movement of the pivotally connected members will be sufficient to maintain said mailbox in a fixed position of adjustment absent the application of additional force to the mailbox or the attachment means.
Claim 2
Dependent Claim
267 words
Attachment means for enabling the adjustable attachment of a mailbox or the like to a vertical support post, said attachment means comprising base bracket means connectable with said post, base pivot means mounted on said base bracket means, elongated base arm means comprising first and second parallel tubular arm members having flattened end surfaces pivotally connected on an inner end to said base bracket means by said base pivot means for pivotal movement with respect to said base bracket, arm pivot means mounted on an outer end portion of said base arm means spaced from the pivotal connection of said base arm means to said base pivot means, outer arm means pivotally connected on one end to said arm pivot means, a connecting bracket including means enabling connection to a mailbox or the like, a connecting bracket pivot means on the end of said outer arm means spaced from the pivotal connection of said outer arm means to said arm pivot means, said connecting bracket being pivotally connected to said connecting bracket pivot means and friction increasing means associated with the pivotal connection between said base arm means and said base bracket means and the pivotal connection between the outer end of said base arm means and the end of the outer arm means pivotally connected thereto and the outer end of the outer arms and the connecting bracket whereby the frictional resistance to pivotal movement of the pivotally connected members will be sufficient to maintain said mailbox in a fixed position of adjustment absent the application of additional force to the mailbox or the attachment means.
Claim 3
Dependent Claim
22 words

Claim 4
Dependent Claim
44 words
The invention of claim 2 wherein said base bracket means includes first and second side plates each dimensioned and shaped to partially engage said post means and each having a forwardly extending support lug with said support lugs extending generally parallel to each other.
Claim 5
Dependent Claim
35 words
The invention of claim 3 wherein said base pivot means comprises a base pivot bolt means extending through apertures in the flattened end surfaces of said base lugs and through apertures in said support lugs.
Claim 6
Dependent Claim
35 words
The invention of claim 4 wherein said arm pivot means comprises an arm bolt extending through apertures in the outer ends of said base arm means and the inner end of said outer arm means.
Claim 7
Dependent Claim
92 words
The invention of claim 5 wherein said connecting bracket means comprises a U-shaped bracket plate including a foot plate and said means enabling connection of said bracket to said mailbox or the like comprises openings in said foot plate, said U-shaped bracket plate additionally including first and second parallel leg plates extending from each end of said foot plate and each provided with an aperture, said bracket pivot means comprising bracket bolt means extending through apertures in the outer ends of said outer arm means and said apertures in said leg plates.
Claim 8
Dependent Claim
64 words
The invention of claim 3 wherein said first and second side plates each includes rearwardly extending threaded rod means, a clamp bar having apertures fitted over said threaded rod members and internally threaded means threadably received on said threaded rod means outwardly of said clamp bar for moving said clamp bar inwardly to clamp a vertical post on which the base bracket is mounted.
Claim 9
Dependent Claim
37 words
The invention of claim 7 additionally including inwardly extending tab members extending inwardly from the upper edge of each of said side plates over the top of the vertical posts with which the base bracket is associated.
