Description
CROSS REFERENCE TO RELATED APPLICATION
[0001] This application claims priority of U.S. Provisional Patent
Application No. 60/728,154, filed 18 Oct. 2005, the entire contents
of which is hereby incorporated by reference.
TECHNICAL FIELD
[0002] The present invention relates generally to a fixed vehicle
barrier device, and in particular to a fixed vehicle barrier device
known as a bollard, which can be mounted in a less than twelve inch
foundation.
BACKGROUND OF THE INVENTION
[0003] In recent years there has been a dramatic increase in the
incidence of attacks on facilities and buildings by terrorists,
other aggressors such as extremists, and even disgruntled employees
throughout the world. Many of these attacks are directed against
government facilities or other high profile locations. One of the
most effective means of facility destruction is through the use of
a vehicle carrying explosives. To successfully guard against such
attacks a standoff distance must be created around the facility.
This can be accomplished by the use of a combination of active and
passive barriers.
[0004] Passive barriers "never" allow vehicular access to certain
areas, while active barriers are utilized to control or limit
vehicular access to a particular area. Passive barriers often
utilize fixed bollards and are used as security barriers to prevent
vehicular access to the perimeter of a facility, outdoor public
areas, campuses, or any other area where it may be desirable to
prevent vehicular traffic.
[0005] Since the Sep. 11, 2000 attacks on the United States, a
significant number of facilities are seeking passive barrier
solutions. The owners of such facilities, as well as the
architectural design community, are demanding a passive barrier
solution that is easier to install and that provides greater
flexibility in installation.
[0006] One concern with current fixed bollard barrier art is the
need to dig a relatively deep foundation, typically four to six
feet, for the installation of the barrier. This depth of foundation
is required to make the barrier robust enough to meet the
Department of State (DOS) crash testing requirements for a 15,000
pound vehicle. Non-crash rated barriers do not require this depth
of foundation. Many city sidewalks and other desirable locations
have various infrastructure (such as pipes and wiring) or other
building structures located eighteen inches or more below the
surface that would prevent the installation of "crash rated"
bollards.
[0007] Another problem of concern comes from current fixed bollard
barriers that have tried to address the foundation depth issue by
building several bollards together into a very large bollard
assembly. These large bollard assemblies require extensive site
surveying and detailed design engineering to allow the pre-designed
bollard assembly to perfectly match the contour of the surface. In
the end this is a virtually impossible task and extremely
expensive.
[0008] What is needed is a fixed vehicle barrier device that can be
mounted in a shallow foundation, while still providing adequate
protection from attack. Further, what is needed is a fixed vehicle
barrier device that can be individually installed in groups without
extensive site surveying and detailed design engineering, while
still meeting the DOS crash rating requirements. It is to such a
device that the present invention is primarily directed.
BRIEF SUMMARY OF THE INVENTION
[0009] Briefly described, in preferred form, the present invention
is a shallow mounted fixed vehicle barrier device for prohibiting
vehicular access to a facility or area. The shallow mounted fixed
vehicle barrier device includes a barrier system having a passive
position and a support system adapted to maintain the barrier
system in the passive position. In the passive position, the
barrier system prevents vehicles from passing by or through to the
protected facility or area. More specifically, the shallow mounted
fixed vehicle barrier device always remains in the passive position
and, therefore, never allows vehicles access to the secured
facility or area.
[0010] The barrier system can include a bollard and, optionally, a
bollard sleeve. The bollard generally stands a significant height
above, and substantially perpendicular to, a foundation, thereby
preventing vehicular access. The bollard is in communication with
the support system, which is typically anchored within the
foundation. The bollard sleeve can be a decorative sleeve that
substantially surrounds the bollard, such that the bollard sleeve
allows the bollard to be decoratively customized to match the
architectural setting of the area or facility.
[0011] The support system can include a base frame anchored to the
foundation via the use of concrete or other similar pavement
substance. The base frame is in communication with the bollard and
is adapted to secure and support the bollard, especially during a
vehicular attack. The base frame includes a plurality of parallel
beams having a first and second plate, such that the first plate
connects the distal ends of the plurality of beams and the second
plate connects the proximate ends of the plurality of beams.
Further, the base frame includes a first foundation foot and a
second foundation foot, wherein the first foundation foot is
connected to the first plate and the second foundation foot is
connected to the second plate. The first foundation foot and the
second foundation foot are adapted to extend outwardly from the
first and second plates, respectively, so as to provide a larger
foundation base for the base frame.
[0012] For adequate connection to the bollard, the base frame
includes a first bollard plate and a second bollard plate, such
that the first and second bollard plates are adapted to secure the
lower portion of the bollard to the base frame. The first bollard
plate is positioned on the top of the base frame and the second
bollard plate is positioned on the bottom of the base frame,
thereby sandwiching the base frame.
[0013] For added support and a stronger foundation, the base frame
can include a plurality of studs that extend from each side of the
base frame. The plurality of studs is adapted to bond with the
concrete or other substance poured into the foundation during
installation of the shallow mounted fixed vehicle barrier device.
Further, the shallow mounted fixed vehicle barrier device can
utilize rebar rods and rebar mats to assist in securing the shallow
mounted fixed vehicle barrier device to the foundation. The rebar
rods and rebar mats are of a particular size and installed in
particular positions, in order to maximize the strength of the
foundation.
[0014] The use of the base frame and rebar rods and mats allows the
shallow mounted fixed vehicle barrier device to be adequately
installed in a foundation having a depth of less than twelve
inches. Accordingly, installation of the shallow mounted fixed
vehicle barrier device does not intrude on infrastructure buried
further below. Moreover, the shallow mounted fixed vehicle barrier
device can be installed in many locations where traditional
bollards could not be installed.
[0015] A principle object of the present invention is to provide a
shallow mounted fixed vehicle barrier device that can be installed
in a foundation having a depth of less than twelve inches.
[0016] Another object of the present invention is to provide a
shallow mounted fixed vehicle barrier device having a bollard and,
optionally, a bollard sleeve adapted to prevent vehicular access to
a particular area or facility.
[0017] Still another object of the present invention is to provide
a shallow mounted fixed vehicle barrier device having an
aesthetically pleasing barrier design that can combine finishes and
colors to match the architectural design of the facility being
secured, thereby giving the engineers and architects, who design
buildings with vehicular intrusion solutions, the ability to
maintain the artistic design of the facility.
[0018] It is another object of the present invention to provide a
shallow mounted fixed vehicle barrier device that comprises a base
frame adapted to maintain the bollard in a fixed, passive
position.
[0019] Yet another object of the present invention is to provide a
shallow mounted fixed vehicle barrier device that adequately bonds
with the concrete or other substance poured within the foundation,
thereby adequately securing the bollard during a vehicular
attack.
[0020] Another object of the present invention is to provide a
shallow mounted fixed vehicle barrier device that eliminates the
need for extensive site surveying and detailed engineering to allow
a large number of bollards to be installed together.
[0021] Still another object of the present invention is to provide
a shallow mounted fixed vehicle barrier device that meets and/or
exceeds the crash test ratings set by the Department of State
(DOS).
[0022] These and other objects, features and advantages of the
present invention will become more apparent upon reading the
following specification in conjunction with the accompanying
drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0028] Referring now in detail to the drawing figures, wherein like
reference numerals represent like parts throughout the several
views, a shallow mounted fixed vehicle barrier device 10 of FIG. 1
is designed for preventing vehicular access to a particular area.
The shallow mounted fixed vehicle barrier device 10 provides an
aesthetically pleasing barrier design, while eliminating multiple
problems of previously designed barriers. The shallow mounted fixed
vehicle barrier device 10 can be configured in various sizes and
shapes conducive to blocking entrance to a restricted area and,
more particularly, for preventing vehicular access to portions of a
particular facility or a particular area.
[0029] As illustrated in FIG. 1, the shallow mounted fixed vehicle
barrier device 10 comprises a barrier system 100 and a support
system 200. The barrier system 100 has a passive (or fixed)
position, such that vehicles cannot pass by or through the shallow
mounted fixed vehicle barrier device 10. The support system 200 is
adapted to maintain the barrier system 100 in the passive position
and, thereby, prevent vehicular access to a particular facility or
area secured by the shallow mounted fixed vehicle barrier device
10. Accordingly, the particular facility or area to be secured by
the shallow mounted fixed vehicle barrier device 10 is never
accessible to vehicles, as the barrier system 100 is always in the
passive position (after installation).
[0030] The barrier system 100 of the shallow mounted vehicle
barrier device 10, as shown in FIG. 1, comprises a bollard 105 and,
optionally, a bollard sleeve 110. When installed and during use,
the bollard 105 is typically upright and substantially
perpendicular to the ground, such that the top of the bollard 105
is at a predetermined height above the ground. The predetermined
height of the bollard 105 is adequate enough to prevent vehicles
from driving over the bollard 105 in an attempt to access the
secure area protected by the shallow mounted vehicle barrier device
10. Typically, the height of the bollard 105 is approximately
thirty to forty inches above the ground. In a preferred embodiment
of the present invention, the bollard 105 is approximately
thirty-six inches above the ground. A predetermined portion of the
bollard 105 is generally installed below the ground and is in
communication with the support system 200.
[0031] In the passive position, the bollard 105 remains fixed in a
substantially perpendicular position from the ground. As the
purpose of the shallow mounted vehicle barrier device 10 is to
prevent vehicular access to a predetermined area or facility, the
bollard 105 should remain in the passive position, even after
impact by a vehicle.
[0032] One skilled in the art will recognize that the bollard 105
can comprise various shapes and sizes, while still maintaining its
intended purpose. Generally, the bollard 105 is a cylindrical tube
made of a durable material. In one embodiment, the bollard 105 is
an upright cylindrical tube constructed from heavy gauge steel
pipe. Further, the bollard 105 can be of varying diameters
depending on the desired crash rating capabilities. For example,
the bollard 105 can have a diameter of approximately eight inches
in order to meet most crash test ratings provided by the DOS.
[0033] The optional bollard sleeve 110 is adapted to substantially
surround the portion of the bollard 105 above the ground. The
bollard sleeve 110, therefore, can be decorative in nature, such
that the bollard 105 can be covered with a bollard sleeve 110
customized to match the architectural setting of the surrounding
area. Accordingly, the decorative bollard sleeve 110 can be
designed in a variety of styles and colors in order to
aesthetically correspond with the landscape of the facility or
secured area.
[0034] The support system 200, as shown in FIGS. 1, 2, and 4,
comprises a base frame 205 anchored into the ground or other
stationary object, whereby the base frame 205 is in communication
with the bottom portion of the bollard 105 of the barrier system
100. The base frame 205 is adapted to maintain and secure the
bollard 105 in a passive position, thereby preventing vehicular
access to the secured area or facility.
[0035] The base frame 205 typically comprises a first beam 210, a
second beam 215, a first beam plate 220, a second beam plate 225, a
first foundation foot 230, a second foundation foot 235, a first
bollard (barrier) plate 240, and a second bollard (barrier) plate
245. The first beam 210 is generally positioned evenly and
substantially parallel to the second beam 215, such that the
distance between the first beam 210 and the second beam 215 is
slightly greater than the diameter of the bollard 105. For example,
and not limitation, the first beam 210 and the second beam 215 can
be steel I-beams having a general length of approximately forty-two
to fifty-four inches. Generally, the length of the first beam 210
and the second beam 215 is slightly greater than the total height
of the bollard 105. Further, the height of the first beam 210 and
the second beam 215 is less than twelve inches. The first beam 210
and the second beam 215 generally have a length substantially equal
to one and a half times the height of the bollard 105.
[0036] The first beam plate 220 is in communication with distal
ends of the first beam 210 and the second beam 215, thereby
indirectly connecting the distal end of the first beam 210 with the
distal end of the second beam 215. The second beam plate 225 is in
communication with proximate ends of the first beam 210 and the
second beam 215, thereby indirectly connecting the proximate end of
the first beam 210 with the proximate end of the second beam 215.
As situated, the width of the first beam plate 220 and the second
beam plate 225 is approximately equal to the width of the first
beam 210, plus the width of the second beam 215, plus the distance
between the first beam 210 and the second beam 215.
[0037] The first foundation foot 230 is in communication with the
lower portion of the first beam plate 220, such that the first
foundation foot 230 is positioned substantially perpendicular to
the first beam plate 220. Further, the first foundation foot 230
extends outwardly away from the first beam plate 220. The first
beam plate 220 and the first foundation foot 230, therefore, form
an "L" shape. Similarly, the second foundation foot 235 is in
communication with the lower portion of the second beam plate 225,
such that the second foundation foot 235 is positioned
substantially perpendicular to the second beam plate 225. Moreover,
the second foundation foot 235 extends outwardly away from the
second beam plate 225. The second beam plate 225 and the second
foundation foot 235, therefore, form an "L" shape. The first
foundation foot 230 and the second foundation foot 235 are adapted
to permit concrete -C- (or other substance) to penetrate under the
base frame 205 of the support system 200, in order to adequately
anchor the base frame 205 into the prepared foundation.
[0038] In a preferred embodiment of the present invention, the
bollard 105 is positioned approximately ten inches from the
proximate ends of the first beam 210 and second beam 215. More
specifically, the bollard 105 is generally positioned in between
the first beam 210 and the second beam 215. The bollard 105 is
secured to the base frame 205 via a first bollard plate 240 and a
second bollard plate 245.
[0039] The first bollard plate 240 is in communication with a first
lower portion of the bollard 105 and the top portions of the first
beam 210 and the second beam 215. As the first bollard plate 240
can be fixed to the top of the first beam 210 and the top of the
second beam 215, the bollard 105 is adequately mounted to the base
frame 205. The second bollard plate 245 is in communication with a
second lower portion of the bollard 105 and the bottom portions of
the first beam 210 and the second beam 215. The second bollard
plate 245 can be fixed to the bottom of the first beam 210 and the
bottom of the second beam 215, thereby further securing the bollard
105 to the base frame 205. As situated, the first bollard plate 240
and the second pollard plate 245 forms a sandwich between the top
and bottom of the first beam 210 and the second beam 215, while
maintaining the connection of the bollard 105 to the base frame
205.
[0040] As shown in FIGS. 4 and 5A-B, the support system 200 of the
shallow mounted fixed vehicle barrier device 10 is anchored in a
foundation. The foundation is an integral part of the shallow
mounted fixed vehicle barrier device 10 and is specifically
designed to maximize the crash rating capabilities of the shallow
mounted fixed vehicle barrier device 10. Typically, for a single
shallow mounted fixed vehicle barrier device 10, the foundation is
approximately five feet to six feet wide and approximately six to
seven feet long (depending on the desired crash rating
capabilities), and is approximately six to twelve inches in depth
.DELTA.d. A foundation having a depth .DELTA.d less than twelve
inches ensures that the shallow mounted fixed vehicle barrier
device 10 will not encounter various infrastructure or other
building structures buried below.
[0041] The support system 200 is lowered into the foundation, such
that the proximate end of the support system 200 (e.g., the end
where the bollard 105 is mounted) faces the direction from which a
potential vehicle attack would occur. For increased stability, the
support system 200 can further comprise a plurality of studs 250,
which extend outwardly from each side of the support system 200.
The plurality of studs 250 is adapted to connect to the surrounding
concrete -C- (or other substance) as it is poured into the
foundation.
[0042] More specifically, a first set of the plurality of studs 250
can extend outwardly from the first beam plate 220, such that the
first set of the plurality of studs 250 is substantially parallel
with the first foundation foot 230. Similarly, a second set of the
plurality of studs 250 can extend outwardly from the second beam
plate 225, such that the second set of the plurality of studs 250
is substantially parallel with the second foundation foot 235.
[0043] A third set of the plurality of studs 250 can be positioned
on the side of the first beam 210 near the proximate end of the
first beam 210. The third set of the plurality of studs 250 extend
outwardly from the first beam 210, such that the third set of the
plurality of studs 250 is substantially perpendicular to the first
beam 210. A fourth set of the plurality of studs 250 can be
positioned on the side of the first beam 210 near the distal end of
the first beam 210. The fourth set of the plurality of the studs
250 extend outwardly from the first beam 210, such that the fourth
set of the plurality of the studs 250 is substantially
perpendicular to the first beam 210.
[0044] A fifth set of the plurality of the studs can be positioned
on the side of the second beam 215 near the proximate end of the
second beam 215. The fifth set of the plurality of studs 250 extend
outwardly from the second beam 215, such that the fifth set of the
plurality of studs 250 is substantially perpendicular to the second
beam 215. A sixth set of the plurality of studs 250 can be
positioned on the side of the second beam 215 near the distal end
of the second beam 215. The sixth set of the plurality of the studs
250 extend outwardly from the second beam 215, such that the sixth
set of the plurality of the studs 250 is substantially
perpendicular to the second beam 215.
[0045] For additional reinforcement, the foundation is constructed
using rebar rods 255 (collectively rebar mats 260) at key locations
within the foundation to connect the base frame 205 of the shallow
mounted fixed vehicle barrier device 10 with the adjoining concrete
-C- (or other substance) and, if applicable, adjacent bollards 105
and base frames. The placement and size of the rebar rods 255 is
important in providing adequate reinforcement to the shallow
mounted fixed vehicle barrier device 10. The rebar mats 260 are
generally located laterally and horizontally at two different
heights within the foundation.
[0046] For example, a first longitudinal rebar mat 260 can be
positioned adjacent the bollard 105 and above the proximate end of
the first and second beams 210, 215. Generally, there exists a
clearance of approximately one and one-half inches between the top
of the base frame 205 to the first rebar mat 260. A second
longitudinal rebar mat 260 can be positioned adjacent the first
beam plate 220, located at the distal end of the first and second
beams 210, 215. There typically exists a clearance of approximately
three inches between the bottom of the base frame 205 and the
second rebar mat 260.
[0047] Additionally, in this example, transverse rebar rods 255 can
be positioned in various positions around the first bollard plate
240 and second bollard plate 245, such that the rebar rods 255 are
adjacent the outer sides of the first and second beams 210, 215. A
third rebar mat 260 can be positioned on top of the base frame 205,
such that the third rebar mat 260 extends from the bollard 105
towards and beyond the distal end of the first and second beams
210, 215, thereby covering the upper portion of the foundation.
[0048] To provide proper reinforcement, the rebar rods 255 and
rebar mats 260 are generally made of #5 or greater rebar. One
skilled in the art, however, will recognize that different sizes of
rebar can be used with the present invention to achieve different
levels of crash rating capabilities.
[0049] During installation, the shallow mounted fixed vehicle
barrier device 10 is lowered into a foundation, as described above.
After the rebar rods 255 and rebar mats 260 have been properly
positioned, concrete -C- (or other substance) is poured into the
foundation, thereby bounding with the rebar rods 255, rebar mats
260, and the plurality of studs 250 extending from the base frame
205. Further, concrete pavers may be installed over the foundation.
If a vehicle crashes into the bollard 105 of the shallow mounted
fixed vehicle barrier device 10, the support system 200 (including
the base frame 205) maintains the bollard 105 in place, thereby
preventing access to the secure area or facility. The present
invention, therefore, provides a substantially effective, passive
vehicle barrier, while utilizing a foundation with a very minimal
depth .DELTA.d.
[0050] As shown in FIG. 3, multiple shallow mounted fixed vehicle
barrier devices 10 can be used in a series or group to secure the
perimeter of a facility or area against vehicular intrusion. The
fixed bollards 105 are typically installed approximately four feet
from each other, such that the bollards 105 are placed in any
opening large enough to allow a vehicle to enter. For example,
several hundred of the shallow mounted fixed vehicle barrier
devices 10 can be used to provide a perimeter protection solution.
One skilled in the art will recognize that the use of multiple
shallow mounted fixed vehicle barrier devices 10 in a variety of
arrangements can be used within the scope of the present
invention.
[0051] Numerous characteristics and advantages have been set forth
in the foregoing description, together with details of structure
and function. While the invention has been disclosed in several
forms, it will be apparent to those skilled in the art that many
modifications, additions, and deletions, especially in matters of
shape, size, and arrangement of parts, can be made therein without
departing from the spirit and scope of the invention and its
equivalents as set forth in the following claims. Therefore, other
modifications or embodiments as may be suggested by the teachings
herein are particularly reserved as they fall within the breadth
and scope of the claims here appended.
