Description
This invention relates to a traffic barricade, and particularly
relates to a vehicle traffic barricade in which component parts are
advantageously formed and assembled; and wherein the barricade is
anchored by improved means when erected.
Traffic barricades of conventional construction have a warning
panel which commonly have reflective materials on opposite faces.
Such reflective materials are commonly presented as traffic
indicators to indicate vehicle direction by conventional diagonal
striping. Such a panel is usually provided with pivoted legs at
each of the opposite sides of a panel, and such legs are collapsed
for storing the barricade; and such legs are extended for erecting
the barricade in use. The legs are further commonly provided with
cross braces which may be removably mounted between the angularly
spaced legs on each side of the panel, or between the straight leg
spacing on each face side of the panel.
Conventional practice of the art provides constructing such
barricade from wood wherein component leg and panel parts are
separately and differently fabricated. The erected barricade must
also be anchored so that weather elements and minor impacts do not
upset the erected barricades. This has been commonly performed by
placing weighted bags across the braces or cross supports between
the legs.
It is an object of the present invention to provide a barricade in
which component parts are more efficiently and more economically
made by integrally forming a plurality of parts in a small number
of configurations so that each basic configuration can be
selectively assembled at any one of a plurality of locations.
Another object of the present invention is a barricade which
permits quick mounting of improved leg support means which
additionally serve as means for anchoring the erected assembly by
receiving weighted material in improved ways.
Yet still another object of the present invention is a barricade in
which leg members are identically molded, and which leg members may
be interchangeably positioned to support a warning panel by pivotal
mountings. A related object is to provide identically formed open
box leg braces which can be similarly mounted between spaced
aligned legs on either face side of the warning panel. A still
further related object is to utilize such open top boxes for more
efficiently receiving weighted materials to anchor the erected
barricade.
Still yet another object is to provide a barricade wherein a molded
warning panel has integrally formed side bearing walls
cooperatively disposed with mounted leg members of identical
construction so that said panel is supported by the leg member in
improved ways.
The foregoing objects are now attained together with still other
objects which will occur to practitioners by the invention of the
following disclosure which includes drawings wherein:
FIG. 1 is a perspective view of the erected barricade assembly;
FIG. 2 is a portional side elevational view of the barricade
assembly in collapsed position;
FIG. 3 is a portional front elevational view, on a reduced scale,
of the interlock box and leg components;
FIG. 4 is a sectional view taken along the line 4--4 of FIG. 2;
FIG. 5 is a portional sectional view taken along the line 5--5 of
FIG. 2;
FIG. 6 is a portional front elevational view of the warning
panel;
FIG. 7 is an end elevational view of the panel shown in FIG. 6;
FIG. 8 is a side elevational view of a leg member;
FIG. 9 is a front elevational view of the leg member shown in the
view of FIG. 8;
FIG. 10 is a top elevational view of an open top box which
supportingly engages spaced aligned leg members;
FIG. 11 is a front elevational view of the box shown in the view of
FIG. 10;
FIG. 12 is an end elevational view of the box shown in the views of
FIGS. 10 and 11; and
FIG. 13 is a sectional view taken along line 13--13 of FIG. 11.
The barricade assembly shown in the view of FIG. 1 illustrates the
major component parts as the reflective panel 14, support legs 16
and a cross brace or open top box 18. Turning now to the views of
FIGS. 8 and 9, the leg members are seen to have an elongated body
portion 20 which is planar, and elongated ribs 22 extending
normally to body portion 20.
The body portion 20 and rib portions 22 impart a cruciform
configuration to the leg members in cross-section. Such cruciform
configuration can be noted, for example, from angled foot portion
23. when the legs are mounted as shown in FIG. 1, the body portion
20 may be considered as comprising a front arm and a back arm
relative to the face of the warning panel 14; and the elongated
ribs 22 may be considered as comprising inside and outside arms
relative to the face of the warning panel 14.
The upper part of the arms have a wing member 26 which is a lateral
extension of the back arm of the elongated body portion 20. Such
wing extension 26 is shown with a mounting bore 27. The lower part
of the leg has a mounting bore 28 which passes through rib 22 or
outside and inside arms of the cruciform configuration of the leg
member.
A box support 24 is formed in the leg member below mounting bore
28. This support has a substantially square cross-sectional
configuration and is formed by support portions extending normally
to the planes of adjoining arms of the cruciform configuration of
the leg member. Supports 24 intercept bottom portions of the box 18
as illustrated in the view of FIG. 1.
The back arm of the leg member is formed with a tapered abutting
face 29 above the wing extension 26. The tapered face 29 abuts
against the face of the warning panel when the legs are extended in
erected position as shown in the view of FIG. 1.
Looking now at FIG. 6, the base of the panel 14 is shown as having
a traffic direction stripe 30 which is usually made from
conventionally available reflective tape. By conventional
indication, the stripes indicate traffic direction to the left
relative to the views shown in the drawings. The panel is shown
with a pair of light assembly mounting bores 32 towards each side
of the panel. Such bores can receive mounting rods from battery
casings of barricade light assemblies which are not shown since
barricade light assemblies do not comprise a part of the present
invention.
The opposite sides 34 of the warning panel are modified at their
lower ends to form inset bearing walls 36. Such bearing walls have
a plane which is normal to the plane of the warning panel. The
bottom of the bearing wall is defined by straight sides, and the
upper part of the bearing wall is defined by tapered sides 38 which
converge to the thickness of the warning panel.
A mounting bore 39 extends through the bearing wall. An inner wall
extension or block 40 is coincidental with straight sides 37 of the
bearing wall, and such extension terminates below mounting bore 39.
Inner wall extension 40 defines the bottom of a square
configuration cutout 42 which communicates with mounting bore 39 to
accommodate a pivot member shown in other views of the drawing.
The open top box, shown in greater detail in the views of FIGS.
10-13, has a pair of spaced elongated side walls 44 and a pair of
spaced end walls 46. A bottom wall 47 forms the floor of a box. The
end walls 46 have a groove 48 extending from the top of the end
wall and terminating short of the bottom wall 47. A slot 49 extends
from the groove 48 to the bottom wall 47, and such slot provides a
passageway to accommodate a fastener as shown in another view of
the drawing. A divider 50 is shown extending between the opposite
pair of side walls 44, such divider separating the chamber of the
box for more conveniently receiving weighted materials.
Referring now to FIGS. 2-5, it is seen that the identically formed
legs can be placed at any of the four possible leg positions. A
mounted pair of leg members at the side of the warning panel have
their wing extensions 26 overlapped so wing extension mounting
bores 27 and the bearing wall mounting passageway 39 form a common
passageway. A pivot member is mounted in this common passageway,
and such pivot member is shown as comprising a bolt element 52 with
the head positioned outside the overlapping wing extensions. A nut
and bolt assembly, commonly indicated as 54, extends into cutout
42.
The box interlock means shown as groove 48 engages the leg
interlock means shown as rib 22, said rib closely fitting the
groove in the end wall of the box. A fastener shown as bolt 56 and
nut 58 is mounted in leg mounting passageway 28 and slot 49 in the
end wall of the box. The fastener and the support 24 cooperate to
position the box along the length of the leg members. The top of
the support 24 intercepts opposite end portions of the bottom wall
47 of the box, and the fastener secures the box to the leg members.
Weighted material of various kinds can be deposited within the box
to anchor the barricade in erected position. A plurality of drain
holes 60 are provided in the side walls 44 along bottom wall 47 to
allow drainage of collected water in the box as from weather,
splashing or the like.
To achieve further advantages of the invention, all the component
parts of the barricade may be molded from plastic material, only
one mold being required for a leg member, another mold for the open
box, and a third mold for the panel. The leg members 16 are
demountably assembled with the panel 14 and the open top boxes 18.
The use of the identically formed parts allows quick and certain
assembly. The boxes 18 are efficiently interlocked with leg members
16, and such boxes are accurately positioned along the length of
the leg members. The use of the open top boxes allows a greater
variety of weight materials to be used than has previously been
possible. Pulverulent materials such as dirt or sand may be
deposited in the box, as well as aggregate, rocks, bricks, or even
sandbags.
The claims of the invention are now presented, and the terms in
such claims may be further understood by reference to the language
of the preceding specification and the views of the drawings.
