Abstract
Abstract A lightweight vertical panel barricade for use on streets and highways in which a first vertical panel is supported and rigidly locked into place by the clamping effect of respective ends of leg support members acting against a wall support of a housing structure disposed at each end of the panel member. The leg support members are rectangular in cross-section and are virtually gripped on three side faces thereof by the housing structures in which they are pivoted, both in their extended, panel support position and their closed, storage position. A second panel member depending from and coplanar with the first panel member is surrounded by the leg members and provides a doubling of the reflective surface of the barricade.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
166 words
A barricade structure having a light reflective means for use in a highway or street, comprising a vertically oriented panel member bearing said light reflective means, said panel member having at opposed portions thereof a pair of oppositely disposed housing structures, each of said housing structures having wall support means, leg member means for supporting said panel member, means for pivotally supporting respective end portions of said leg member means in each of said housing structures, whereby a bearing face of each of said respective end portions of said leg member means bears against said wall support means for rigidly supporting said panel member in its vertical position when said leg member means is in a first, extended position, and said bearing face being free of contact with said wall support means, and said respective end portions of said leg member means being wholly contained within the periphery of each of said housing structures when said leg member means is in a second, closed storage position.
Claim 2
Dependent Claim
166 words
A barricade structure having a light reflective means for use in a highway or street, comprising a vertically oriented panel member bearing said light reflective means, said panel member having at opposed portions thereof a pair of oppositely disposed housing structures, each of said housing structures having wall support means, leg member means for supporting said panel member, means for pivotally supporting respective end portions of said leg member means in each of said housing structures, whereby a bearing face of each of said respective end portions of said leg member means bears against said wall support means for rigidly supporting said panel member in its vertical position when said leg member means is in a first, extended position, and said bearing face being free of contact with said wall support means, and said respective end portions of said leg member means being wholly contained within the periphery of each of said housing structures when said leg member means is in a second, closed storage position.
Claim 3
Dependent Claim
26 words
A barricade structure according to claim 1, wherein said housing structures and portions of said vertically oriented panel have substantially the same width and are coplanar.
Claim 4
Dependent Claim
27 words
A barricade structure according to claim 1, wherein said light reflective means comprises a striped array of injection molded reflective elements on opposite sides of said panel.
Claim 5
Dependent Claim
22 words
A barricade structure according to claim 1, wherein said light reflective means comprises a reflective sheeting on opposite sides of said panel.
Claim 6
Dependent Claim
39 words
A barricade structure according to claim 1, wherein said leg member means is generally hollow and rectangular in cross-section, and further comprising an auxiliary support leg means having a means for admitting a weighting agent to the interior thereof.
Claim 7
Dependent Claim
29 words
A barricade structure according to claim 1, wherein said panel member comprises a boss means thereon for enabling the attachment of a lighting fixture means to said panel member.
Claim 8
Dependent Claim
39 words
A barricade structure according to claim 1, wherein said housing structures each have discrete bearing surface portions disposed on selected side walls thereof for slidably bearing against a part of said respective end portions of said leg member means.
Claim 9
Dependent Claim
39 words
A barricade structure according to claim 1, wherein said pivotal support means comprises a U-bolt means, the respective legs of which each extend through each of said housing structures and said respective end portions of said leg member means.
Claim 10
Dependent Claim
119 words
A barricade structure having a light reflective means for use in a highway or street, comprising a vertically oriented panel member bearing said light reflective means, said panel member having at opposed portions thereof a pair of oppositely disposed housing structures, each of said housing structures having wall support means, leg member means for supporting said panel member, and means for pivotally supporting respective end portions of said leg member means in each of said housing structures, whereby a bearing face of each of said respective end portions of said leg member means bears against said wall support means for rigidly supporting said panel member in its vertical position when said leg member means is in an extended position.
Claim 11
Dependent Claim
119 words
A barricade structure having a light reflective means for use in a highway or street, comprising a vertically oriented panel member bearing said light reflective means, said panel member having at opposed portions thereof a pair of oppositely disposed housing structures, each of said housing structures having wall support means, leg member means for supporting said panel member, and means for pivotally supporting respective end portions of said leg member means in each of said housing structures, whereby a bearing face of each of said respective end portions of said leg member means bears against said wall support means for rigidly supporting said panel member in its vertical position when said leg member means is in an extended position.
Claim 12
Dependent Claim
182 words
A barricade structure having a light reflective means for use in a highway or street, comprising a vertically oriented panel member bearing said light reflective means, said panel member having at opposite ends thereof a pair of oppositely disposed housing structures, each of said housing structures having a median wall support and end walls normal thereto for defining a channel space on either side of said median wall support, leg member means for supporting said panel member, means for pivotally supporting respective end portions of said leg member means in said channel space, whereby a bearing face of each of said respective end portions of said leg member means bears against said wall support for rigidly supporting said panel member in its vertical position when said leg member means is in a first, extended position, and said bearing face being free of contact with said wall support, and said respective end portions of said leg member means being wholly contained within said channel space of each of said housing structures when said leg member means is in a second, closed storage position.
