Abstract
Abstract This resilient sign post mounting includes a ground attached lower section, a separate upper section for carrying the sign and a resilient connection between the upper and lower sections. The resilient connection is provided by a bundle of rods securely clamped to one section and relatively loosely attached to the other section so that the rods can slide relative to each other when the upper and lower sections are moved temporarily out of alignment under impact with a vehicle.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
133 words
A resilient mounting for a sign post, comprising: a. a lower post section adapted to be fixed in cantilever relation to the ground, b. an upper post section spaced from the lower post section but substantially aligned therewith in a normal condition, c. a resilient connection between said upper and lower post sections including: 1. a bundle of elongate rods having a longitudinal axis extending between opposed ends and disposed in side-by-side relation, 2. first fastener means connecting one end of said bundle to one of said post sections and second fastener means connecting the other end of said bundle to the other of said post sections, and 3. at least one of said fastener means permitting said rods to move relative to each other when the post sections are misaligned following impact.
Claim 2
Dependent Claim
133 words
A resilient mounting for a sign post, comprising: a. a lower post section adapted to be fixed in cantilever relation to the ground, b. an upper post section spaced from the lower post section but substantially aligned therewith in a normal condition, c. a resilient connection between said upper and lower post sections including: 1. a bundle of elongate rods having a longitudinal axis extending between opposed ends and disposed in side-by-side relation, 2. first fastener means connecting one end of said bundle to one of said post sections and second fastener means connecting the other end of said bundle to the other of said post sections, and 3. at least one of said fastener means permitting said rods to move relative to each other when the post sections are misaligned following impact.
Claim 3
Dependent Claim
62 words
A resilient mounting for a sign post as defined in claim 1, in which: d. the first fastener means connects said one end of said bundle to said one post section in substantially fixed relation and the second fastener means connects said other end of said bundle to said other post section to permit said rods to move relative to each other.
Claim 4
Dependent Claim
131 words
A resilient mounting for a sign post as defined in claim 2, in which: e. the first fastener means includes a U-bolt having an axis transverse to the axis of the rod bundle, said U-bolt being connected to its associated post section in coacting relation with said post section to embrace and clamp the rods to said post section, f. the second fastener means includes a U-bolt having an axis transverse to the axis of the rod bundle, said U-bolt being connected to its associated post section in coacting relation with said post section to embrace and hold the rods to said post section sufficiently loosely to permit relative sliding motion between said rods in a longitudinal direction and yet sufficiently tightly to maintain the elevation of the upper post section.
Claim 5
Dependent Claim
158 words
A resilient mounting for a sign post as defined in claim 2, in which: e. the upper and lower post sections provide elongate channels having a bight portion, f. the rod bundle is at least two rods in width in a direction parallel to said bight portion and at least two rods in width in a direction perpendicular to said bight portion, g. the first fastener means includes a U-bolt having opposed ends connected to its associated post section, said U-bolt coacting with said post section to embrace and clamp the rods to said post section, and h. the second fastener means includes a U-bolt having opposed ends connected to its associated post section, said U-bolt coacting with said post portion to embrace and hold the rods to said post portion sufficiently loosely to permit relative sliding motion between said rods in a longitudinal direction and yet sufficiently tightly to maintain the elevation of the upper post section.
