Claim 5

A barricade as defined in claim 2 wherein the second pair of legs includes an upper cross-member attached at top portions of the second pair of rigid legs by separate flexible, resilient, elastic connecting members.

Claim 6

A barricade as defined in claim 1 wherein the said at least one pair of separate elastic, connecting members have a U-shape with opposing open and closed ends as first and second ends which are attached at the first attachment means on the legs and at the second attachment means of the cross-member.

Claim 7

A barricade as defined in claim 5 wherein the first end of the U-shaped member comprises the open end of the U with respective legs of the U being removably attached to top portions of the pair of rigid legs of the barricade, the second end comprising the closed end of the U-shaped member which is inserted through the second attachment means comprising an opening in the cross-member.

Claim 8

A barricade as defined in claim 6 wherein the first attachment means comprises a pair of openings in the top portion of the legs, said first, open end of the U-shaped connecting member being compressibly inserted through the openings in said top portion of the legs and further including deformable stops on the first, open end thereof which are larger than the leg openings to releasably retain the first, open end or said U-shaped connecting member in said openings when the connecting member is deformed during an impact.

Claim 9

A barricade as defined in claim 5 wherein the second end of the U-shaped member comprises the open end of the U with legs of the U being attached to the cross-member, the first end comprising the closed end of the U which is inserted through an opening comprising the first attachment means in the top portion of the pair of legs.

Claim 10

A barricade as defined in claim 8, wherein the first, closed end of the U-shaped member includes a finger projection adapted for insertion through the first attachment opening, the finger having an extended distal end which includes a head larger in size than the first opening to releasably retain the first end of the U-shaped member inserted in the attachment openings of said rigid legs during deformation resulting from an impact.

Claim 11

A barricade as defined in claim 8, wherein the second, open end of the U-shaped member is adapted for insertion of the cross-member between extending fingers of the U, the fingers and cross-member having openings therein adapted for alignment, said barricade further including a retaining pin inserted through the finger and cross-member openings.

Claim 12

A barricade as defined in claim 2, further comprising light coupling means for attaching a light signalling device at the top of said pairs of legs to adapt the barricade for night use.

Claim 13

A barricade as defined in claim 11, wherein the leg coupling means attached between the respective first and second pair of legs also comprises the light coupling means for attaching the signalling device, said coupling means comprising a mounting plate having a pair of openings for bolting one side of the respective legs thereto, said mounting plate having a third opening adapted for retaining a mounting bolt for attachment of the signalling device, the coupling means further including a bracket adapted for positioning a remaining, opposite side of the legs from the mounting plate such that the legs are rigidly secured between the mounting plate and bracket to prevent the signalling device from being wrenched from the barricade during the impact.

Claim 14

A detachable cross-member for providing traffic delineation and visual notice of a road hazard and being adapted for horizontal attachment between upright legs as part of a self-supported traffic control device, said member comprising: an elongated, rigid support plate having openings at each side for attachment and at least one face with substantial surface are adapted for receiving reflective material responsive to vehicle headlights for giving warning to on-coming traffic; at least one pair of separate flexible, elastic, resilient connecting members having first and second attachment ends wherein (i) the second attachment ends are coupled to said openings of the support plate and operate to position the first pair of attachment ends in an extended, free position, (ii) said first attachment ends of the connecting members being adapted for attachment to a pair of rigid legs which support the detachable cross-member in a horizontal, sturdy configuration; said first attachment ends including an extended distal end adapted for inserting through openings in the pair of legs to facilitate pulling the first attachment ends through the said openings in said pair of rigid legs to a seated position against the legs; the separate, flexible connecting members and plate attachment means forming a resilient, elastic joint between said pair of rigid legs and said rigid support plate capable of stretching when subjected to conditions of stress to allow the pair of legs and attached detachable cross-member to deform from said sturdy configuration under impact without damaging the rigid legs or support plate and which can be subsequently restored to the sturdy configuration by merely repositioning or reattaching the first and second attachment ends of the resilient, flexible connecting members at the rigid legs and support plate attachment means respectively and by repositioning the deformed structure to the original, sturdy configuration.

Claim 15

A detachable cross-member for providing traffic delineation and visual notice of a road hazard and being adapted for horizontal attachment between upright legs as part of a self-supported traffic control device, said member comprising: an elongated, rigid support plate having openings at each side for attachment and at least one face with substantial surface are adapted for receiving reflective material responsive to vehicle headlights for giving warning to on-coming traffic; at least one pair of separate flexible, elastic, resilient connecting members having first and second attachment ends wherein (i) the second attachment ends are coupled to said openings of the support plate and operate to position the first pair of attachment ends in an extended, free position, (ii) said first attachment ends of the connecting members being adapted for attachment to a pair of rigid legs which support the detachable cross-member in a horizontal, sturdy configuration; said first attachment ends including an extended distal end adapted for inserting through openings in the pair of legs to facilitate pulling the first attachment ends through the said openings in said pair of rigid legs to a seated position against the legs; the separate, flexible connecting members and plate attachment means forming a resilient, elastic joint between said pair of rigid legs and said rigid support plate capable of stretching when subjected to conditions of stress to allow the pair of legs and attached detachable cross-member to deform from said sturdy configuration under impact without damaging the rigid legs or support plate and which can be subsequently restored to the sturdy configuration by merely repositioning or reattaching the first and second attachment ends of the resilient, flexible connecting members at the rigid legs and support plate attachment means respectively and by repositioning the deformed structure to the original, sturdy configuration.

Claim 16

A barricade as defined in claim 1 further comprising a weighted cross-member adapted for attachment at a base portion of a traffic barricade, said weighted cross-member comprising: an elongated support member having a length greater than the distance between supporting legs of the barricade to which the weighted cross-member is to be attached, said support member having sufficient strength to support the weighted cross-member without substantial sagging; at least one weighted tube having closed end sections which adapt the tube for mounting on the elongated member, said closed end sections being configured to form a close fit around the elongated member to thereby retain sand or other heavy substance therein.
