Abstract
Abstract A traffic lane control system for selectively partitioning a multi-lane roadway includes two transversely spaced collapsible, inverted V-section guard barriers (56, 58) each formed by two elongate panels (22, 24; 28, 30) having their adjacent sides hinged together (50, 44) and their outer longitudinal sides hinged (53, 48, 46, 51) to the respective adjacent roadway sections (32, 26, 24), one of said barriers being in raised divider position, while the other one is spread out flat and forms part of the roadway. The roadway section intermediate between the barriers (56, 58) is a panel (26) mounted for reciprocation tranversely to the roadway; shifting said roadway panel (26) by means of a horizontal hydraulic jack (64) located under the roadway causes the raised barrier to spread down flat and the other barrier to concurrently jack-knife up to divider position.Vertical hydraulic jacks (62, 60) are provided below the barriers to initiate jack-knifing thereof.

Claim 2
Dependent Claim
49 words
A collapsible barrier for dividing a roadway having a plurality of traffic lanes, comprising a plurality of barrier panels (22,24,28,30) having adjacent sides hinged together; and means (60,62 and 64) for elevating at least one pair of adjacent panels to form a barrier (56,58) for separating the traffic lanes.
Claim 3
Dependent Claim
154 words
A barrier according to claim 1 characterised by means (62 and 64) for selectively elevating a first hinge (50) to erect a first barrier (56) comprising a first barrier panel (22) connected to the first hinge (50) and a second barrier panel (24) connected to the first hinge (50), the first barrier (56) being adjacent a first side of the roadway (32) and providing a traffic lane over the array adjacent a second side of the roadway; and means (60 and 64) for selectively elevating a second hinge (44) to remove the first barrier (56) and to erect a second barrier (58) comprising a third barrier panel (28) connected to the second hinge (44) and a fourth barrier panel (30) connected to the second hinge (44), the second barrier (58) being adjacent the second side (34) of the roadway and providing a traffic lane over the array adjacent the first side of the roadway.
Claim 4
Dependent Claim
24 words
A barrier according to claim 1 or 2 characterised by means (53,51) for hingedly mounting a pair of the barrier panels to the roadway.
Claim 5
Dependent Claim
29 words
A barrier according to claim 1 to 3 characterised in that the hinges (44,46,48,50,51 and 53) lock when the barrier panels are elevated to provide rigidity to the barrier.
Claim 6
Dependent Claim
29 words
A barrier according to claim 4 characterised in that the hinges (44,46,48,50,51 and 53) have an unlocked position for each barrier panel to permit removal thereof from the array.
Claim 7
Dependent Claim
48 words
A barrier according to claim 2 characterised in that the means for selectively elevating the first hinge comprises means (62) placed under the first or second barrier panels (22 or 24) for lifting the first hinge (50) to elevate the first and second barrier panels (22 and 24).
Claim 8
Dependent Claim
24 words
A barrier according to claim 6 characterised in that the means placed under the first or second barrier panel comprises a hydraulic jack (62).
Claim 9
Dependent Claim
72 words
A barrier according to claim 6 or 7 characterised in that the means for selectively elevating the first hinge further comprises actuator means (64) having a first end (66) fixed under the roadway (32) and a second end (68) connected to the array for selectively moving the array laterally with respect to the roadway selectively to erect one of the first and second barriers (56 and 58) and remove the other barrier.
Claim 10
Dependent Claim
15 words
A barrier according to claim 8 wherein the actuator means comprises a hydraulic ram 64.
Claim 11
Dependent Claim
36 words
A barrier according to any of claims 1 to 9 characterised by a support (106,108) connected to selected hinges (44,50) the support depending from the selected hinges (44,50) to provide vertical support to the barrier (50,44).
Claim 12
Dependent Claim
68 words
A barrier according to claim 10, characterised in that a flange (112) extending from the support (106,108) to rest upon a base (112,110) when the hinge (50,44) connected to the support (106,108) is in its lower position and to hang between the panels (22,24,28,30) connected to the hinge (50,44) when the hinge is in its upper position to limit the range of hinging movement of the elevated panels.
Claim 13
Independent Claim
