Abstract
Abstract A collapsible barricade suitable for use in street traffic control. The barricade comprises a support and a plate or sign. The support includes pairs of divergently pivoted legs having jaws for gripping the sign. The sign is a rectangularly shaped uniplanar element having configurated slots spaced along its edge and is adapted for interlocking engagement with the jaws to form a substantially rigid and stable structure. Toggle links provided on each of the pairs of legs have a latching mechanism by which the legs may be retained in an expanded position to prevent removal of the sign from the jaws.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
198 words
A barricade comprising, in combination, a sign element and pairs of support legs, said sign element consisting of a generally rectangular thin plate, said plate having opposed ends and a configured slot defined in each of such opposed ends, said configured slot including a throat passageway and upper and lower recesses communicating with such throat passageway and extending away from such throat passageway, each of said pairs of support legs comprising longitudinally extending angles having integral right-angle flanges, one of said angle flanges of each leg forming a gripping jaw adjacent the upper end of each leg, a cooperating porTion of the other one of said flanges on at least one of said pairs of legs having a shape complementary with the shape of such upper recesses, whereby relative rotation between said barrier plate and said legs is prevented when said cooperating portion is positioned within such upper recess, and pivot means spaced below said gripping surfaces for pivotally connecting said pair of support legs, wherein said gripping jaws are against opposed sides of said thin plate and wherein said cooperating portion is received and held in such complementary recess when said barricade is in an operative position.
Claim 2
Dependent Claim
198 words
A barricade comprising, in combination, a sign element and pairs of support legs, said sign element consisting of a generally rectangular thin plate, said plate having opposed ends and a configured slot defined in each of such opposed ends, said configured slot including a throat passageway and upper and lower recesses communicating with such throat passageway and extending away from such throat passageway, each of said pairs of support legs comprising longitudinally extending angles having integral right-angle flanges, one of said angle flanges of each leg forming a gripping jaw adjacent the upper end of each leg, a cooperating porTion of the other one of said flanges on at least one of said pairs of legs having a shape complementary with the shape of such upper recesses, whereby relative rotation between said barrier plate and said legs is prevented when said cooperating portion is positioned within such upper recess, and pivot means spaced below said gripping surfaces for pivotally connecting said pair of support legs, wherein said gripping jaws are against opposed sides of said thin plate and wherein said cooperating portion is received and held in such complementary recess when said barricade is in an operative position.
Claim 3
Dependent Claim
77 words
A barricade according to claim 1, including downwardly directed prongs defined by said legs below said pivot means, a recess opening defined by each of said other flanges adjacent said prong, such recess opening of one of said legs being aligned with such recess opening of the other leg when said barricade is in the operative position, whereby such aligned recess openings mate with such lower recess and said prongs abut the opposed sides of said plate.
Claim 4
Dependent Claim
36 words
A barrier according to claim 1, wherein each of said pairs of legs are provided with toggle means, said toggle means including latch means associated therewith adapted for releasably holding said jaws in a gripping position.
Claim 5
Dependent Claim
46 words
A barrier according to claim 1, wherein said plate has a longitudinal central axis and has on opposed sides at least one configured slot lying at a predetermined angle with said axis, whereby said plate may be supported at an angular position relative to said legs.
Claim 6
Dependent Claim
33 words
A barrier according to claim 1, wherein said plate has at least one opening therethrough adapted to receive a connecting member, whereby said barrier may be connected to one or more other barriers.
Claim 7
Dependent Claim
155 words
A barricade comprising, in combination, a barrier plate having front and back surfaces and having at least one configured end slot extending therethrough adjacent each end, said configured slot including a throat passageway and upper and lower noncircular recesses, a pair of support legs positioned at each end of said plate, said support legs having a pair of opposed jaws at its upper ends adapted to engage said front and back surfaces of said plate, a projection on one of said legs extending in a plane perpendicular to said barrier plate, said projection being complementary with and received by said upper noncircular recess when said barricade is in an operative position, whereby relative rotation between said barrier plate and said legs is prevented when said projection is positioned within such upper recess, pivot means connecting said legs, and toggle means adapted to engage said legs when said jaws are in gripping engagement with said plate.
Claim 8
Dependent Claim
155 words
A barricade comprising, in combination, a barrier plate having front and back surfaces and having at least one configured end slot extending therethrough adjacent each end, said configured slot including a throat passageway and upper and lower noncircular recesses, a pair of support legs positioned at each end of said plate, said support legs having a pair of opposed jaws at its upper ends adapted to engage said front and back surfaces of said plate, a projection on one of said legs extending in a plane perpendicular to said barrier plate, said projection being complementary with and received by said upper noncircular recess when said barricade is in an operative position, whereby relative rotation between said barrier plate and said legs is prevented when said projection is positioned within such upper recess, pivot means connecting said legs, and toggle means adapted to engage said legs when said jaws are in gripping engagement with said plate.
Claim 9
Dependent Claim
25 words
A barricade according to claim 6 wherein said barrier plate has at least one opening therein adapted to receive a portion of a connecting chain.
Claim 10
Dependent Claim
