[0001] This invention concerns barriers of the kind placed around a construction or road
repair site for the protection of pedestrians and of the type where a number of such
barriers may be linked together for crowd control at events.
[0002] Conventionally, such barriers are approximately 2 metres in length and 1 metre high
and generally comprise a panel, apertured to avoid wind resistance and having a pair
of feet which are rotatable from an operative position extending transversely to the
barrier to support it in an upright position, to a position aligned with the longitudinal
centre line thereof for stacking and transportation.
[0003] Such feet often present a trip hazard to pedestrians and it is an object of the present
invention to provide a pedestrian control barrier in which such hazard is substantially
reduced.
[0004] According to the present invention there is provided a pedestrian or traffic barrier
comprising an elongate panel and at least two ground engaging portions to support
the panel upright on the ground; characterised in that the ground engaging portions
are in fixed disposition on the panel and are offset from a longitudinal centre line
thereof thus to avoid presenting a trip hazard.
[0005] Preferably, one ground engaging portion extends from one face of the panel in a central
region of the panel, and two further ground engaging portions are located in opposed
end regions of the panel.
[0006] At least one of the ground engaging portions extends obliquely from the panel.
[0007] Preferably, the end regions of the panel are curved away from said longitudinal centre
line, and each terminates in a foot extending generally parallel to said longitudinal
centre line.
[0008] Said one ground engaging portion may be V-shaped in plan tapering upwardly to merge
with said one face of the panel, the sides of the V defining therewith an angle in
excess of 120°, and preferably in the region of 150°.
[0009] The panel may be of one-piece moulded construction having a hollow interior.
[0010] The hollow interior may include at least one enclosed chamber to contain ballast.
[0011] The enclosed chamber may include a closable port to enable filling and disposal of
the ballast.
[0012] The ground engaging portions may be disposed with respect to the panel and to each
other so as to minimise the risk of tilting about the longitudinal centre line.
[0013] The curved end region of the panel may be of reducing cross-section to enable face
to face stacking of a plurality of said panels and their respective ground engaging
portions.
[0014] Opposed end portions of the panel may be spaced laterally with respect to the longitudinal
centre line of the panel sufficiently to permit a stack of panels to be engaged by
the forks of a forklift truck without the use of a pallet.
[0015] The barrier may be produced by blow moulding of a high density polyethylene.
[0016] The barrier may have formations enabling a plurality of such barriers to be linked
together end to end, and to enable attachment thereto of one or more lanterns.
[0017] The barrier may be apertured to avoid wind resistance.
[0018] An embodiment of the invention will now be described, by way of example only, with
reference to the accompanying drawings in which:
Fig. 1 is a perspective view of a barrier made in accordance with the invention;
Fig. 2 is a plan view;
Fig. 3 is an underside view; and
Fig. 4 is an elevation.
[0019] Referring now to the drawings, the barrier 10 comprises an elongate panel 11 and
at least two ground engaging portions comprising a central foot 12 and opposed end
feet 13.
[0020] The barrier is of one-piece moulded construction produced by blow moulding from high
density polyethylene and thus has a hollow interior. The interior is walled to produce
three enclosed chambers 14, 15 and 16 above the feet 12 and 13, with closable ports
17 enabling the chambers to be filled with ballast such as water or sand. The chambers
may be emptied for storage and/or transportation of the barrier.
[0021] It will be seen from Figs. 1 to 3 that the panel 11 has a longitudinal centre line
illustrated at 18 in Fig. 2 with end region curvature 19 terminating in the ground
engaging feet 13 disposed, therefore, on one side of the centre line 18 while the
ground engaging foot 12 lies on the opposite side of the centre line 18. The foot
12 which is generally in the central region of the panel is v-shaped in plan tapering
upwardly to merge with the adjacent face of the panel as can be seen in Fig. 1.
[0022] As can be seen in Fig. 3 the foot 12 is undercut with respect to the opposite face
of the panel thus forming a V-shaped recess 25. The sides of the V define with their
respective faces of the panel an angle in excess of 120° and preferably in the region
of 150°. It can therefore be seen that the foot 12 is obliquely displaced from the
adjacent face of the panel so that a pedestrian's foot engaging the foot 12 of the
panel would glance off the latter and thus avoid the trip hazard which would otherwise
be present in a foot extending normal to the face of the panel.
[0023] Similarly, the feet 13 at the terminal ends of the curved end portions 19 once again
are designed to avoid a trip hazard while providing adequate support for the barrier
in conjunction with the foot 12, the feet 12 and 13 lying on opposite sides of the
longitudinal centre line 18.
[0024] As can be seen from Figs. 2 and 3, the ground engaging feet 12 and 13 are disposed
with respect to the panel and to each other so as to minimise the risk of tilting
about the centre line 18.
[0025] Also as can be seen from Figs. 2 and 3, the curved end regions 19 of the panel are
of reducing cross-section to enable face to face stacking of a plurality of such barriers
and their respective ground engaging feet.
[0026] Further as can be seen from Figs. 2 and 3, the opposed end portions of the panel
are spaced laterally with respect to the longitudinal centre line 18 thereof sufficiently
to permit a stack of panels to be engaged by the forks of a forklift truck without
the need for a pallet. Thus stacks of such panels can be manoeuvred from place to
place more readily.
[0027] End formations 20 and 21 are provided to enable a plurality of such barriers to be
linked together end to end, and further formations one of which is illustrated at
22 are provided on opposed faces of the barrier for attachment of warning lanterns.
The barrier is apertured by a series of upright slots 23 along its length to minimise
wind resistance and to reduce its weight. An elongate upper region 24 on each face
of the panel 11 is provided for reflective or other high visibility material.
[0028] A barrier produced in accordance with the invention is of increased stability when
compared with conventional flat barriers having detachable and rotatable feet, and
has no surface extending at right angles to the general plane of the barrier which
could cause a trip hazard. Being of one-piece moulded construction the barrier is
less expensive to produce when compared with conventional barriers, is lightweight
and readily stackable.
[0029] It is not intended to limit the invention to the above example only, many variations
being possible without departing from the scope of the appended claims. For example,
the barrier may have more than one V-shaped protruding foot extending from an otherwise
flat or flatter barrier.
