Abstract

A mobile barrier system includes a wheeled trailer base having a front end from which a towing assembly extends for attachment to a towing vehicle and a set of panels that are moveable between a compact transport state and a deployed state. The set of panels includes a back panel mounted to and extending upward from a back end of the wheeled trailer base, first and second side panels hinged along side margins of the back panel and operable to swing relative to the back panel, and first and second front panels hinged along ends of the side panels and operable to swing relative to the side panels. The first and second front panels angle at an obtuse angle from its corresponding side panel toward the towing vehicle when in the compact transport state to form a V-shaped pointed nose for the wheeled trailer base.

Description

mobile barrier foreign application 69662/25:1 MOBILE BARRIER SYSTEM
Technical Field [0001] This disclosure relates to a mobile barrier system, particularly to a mobile barrier for use in crowd control, emergency response, or other military and law enforcement applications.

Background Information [0002] Barriers can be used in a variety of applications in which protection of persons and/or property is desired. For example, barriers are particularly useful for law enforcement personnel to control crowds of people, control traffic flow, and secure crime scenes. In many applications, barriers are used on a temporary basis.
Accordingly, it is desirable to have a barrier that is easy to transport, assemble, and disassemble.

[0003] U.S. Patent Application Publication No. 2010/0101156 describes a mobile barrier system that includes a series of panels attached to a wheeled transportation unit such as a trailer. The series of panels includes two side panels that are hinged to a back stationary panel so that the side panels can transition between a collapsed position and a deployed position. In the collapsed position, the side panels form side walls for the wheeled transportation unit. In the deployed position, the side panels align with the back panel to form a co-planar wall that serves as a barrier.

[0004] The present inventors have developed a mobile barrier system having increased transportability and functionality.

Detailed Description of Preferred Embodiments [0016] Figs. 1 and 2 are perspective views of a mobile barrier system 100 in a deployed state according to one embodiment. Mobile barrier system 100 includes a mobile barrier foreign application 69662/25:1 wheeled trailer base 102 that has a towing assembly 104 extending from a front end 106 of base 102. Towing assembly 104 enables mobile barrier system 100 to be attached to a towing vehicle (not shown) and transported to different locations. In one embodiment, base 102 is suitable for military applications in which base 102 has a relatively high ground clearance and can carry relatively heavy loads compared to standard flatbed utility trailers. Mobile barrier system 100 may also include run flat tires and may be capable of traveling off-road. In some applications, mobile barrier system 100 may be designed to ford bodies of water.

[0017] Mobile barrier system 100 includes a set of panels that form a barrier (e.g., a wall) in the deployed state. The panels include a back panel 108 at a back end 110 of base 102. Back panel 108 includes first and second side margins 112 and 114 along which first and second side panels 116 and 118 are coupled via hinges 120. Side panels 116 and 118 include ends 122 and 124 along which first and second front panels 126 and 128 are coupled via hinges 130. In the configuration shown in Figs. 1 and 2, side panels 116 and 118 extend outward from side margins 112 and 114, and front panels 126 and 128 extend outward from ends 122 and 124, to form a substantially co-planar barrier wall. Side panels 116 and 118 swing relative to back panel 108 about hinges 120 (as indicated by arrows 134 and 136), and front panels 126 and 128 swing relative to side panels 116 and 118 about hinges 130 (as indicated by arrows 138 and 140), to transition between the deployed state and a compact transport state shown in Fig 11. Drop-down casters 142 and 144 are secured along bottom edges of side panels 116 and 118 to facilitate movement of side panels 116 and 118 between the deployed state and the compact transport state. Casters 142 and 144 are provided near ends 122 and 124 on inward sides (sides closes to base 102) of side panels 116 and 118. Casters 142 and 144 may include a slide assembly that enables casters 142 and 144 to be retracted upward and locked in place during transportation of system 100 and during deployment.
The slide assembly allows, casters 142 and 144 to be extended downward to contact the ground to thereby facilitate pivoting movement of side panels 116 and 118 about hinges 120 between the deployed state and the compact transport state. Panels 108, 116, 118, 126, and 128 may include skirts 145 along their bottom edges to impede access under the panels. Panels 116 and 118 may include viewing windows 146, as shown in Fig. 2, made of bulletproof glass that enable a person standing mobile barrier foreign application 69662/25:1 behind the inward side of panels 116 and 118 to see events occurring behind the outward side of panels 116 and 118. Viewing windows 146 may be covered with removable doors 147, as shown in Fig. 1, positioned on the inward side of panels 116 and 118. Moreover, viewing windows 146 may also be made of one-way viewing glass so that only persons standing behind the inward side of panels and 118 can see through viewing windows 146. Side panels 116 and 118 may also include openings 148 or hatches that may be covered with removable doors 149 positioned on the inward side of panels 116 and 118. Openings 148 may be uncovered so that items may be passed through panels 116 and 118.

[0018] Back panel 108 includes a fold down door 200 shown in an upright closed position in Figs. 1 and 2. In the upright closed position, door 200 may be securely locked in place via a conventional locking mechanism such as a latch and lock.
As shown in Fig. 3, door 200 folds down to form a ramp to allow items to be easily moved on and off of base 102. For example, door 200 may form a ramp to allow a vehicle (e.g., a motorcycle, an all-terrain vehicle (ATV)) to be easily loaded onto base 102 so that the vehicle can be transported with system 100. In one application, base 102 may serve as a security checkpoint and door 200 drops down to form a ramp that people can ascend to efficiently move up onto base 102 to pass through the security checkpoint. Door 200 includes a biasing mechanism 202 (e.g., a gas shock, spring) to assist a user when opening and closing door 200. Biasing mechanism 202 preferably excludes retractable cables extending between door and back panel 108, such as cables used in conventional ramp door spring assists, so that personnel and equipment do not become entangled with biasing mechanism 202 when door 200 is open.

[0019] Support struts 204 are positioned between back panel 108 and base 102 to provide stability for back panel 108. As shown in Fig. 2, system 100 includes retractable stabilizer legs 206 and 207 that can be extended to engage the ground (as demonstrated by stabilizer leg 206) and retracted (as demonstrated by stabilizer leg 207) to allow system 100 to be transported. As shown in Fig. 1, system 100 also includes drop-down side panel supports 208 and 210 positioned on side panels and 118 that can be lowered to engage the ground, as demonstrated by support 208, or raised and folded adjacent to its corresponding side panel in a stowed position, as mobile barrier foreign application 69662/25:1 demonstrated by support 210. Retractable support jacks 211 are also provided on front end 106 of base 102. One or more of jacks legs 206 and 207, supports 208 and 210, and jacks 211 may be anchored to the ground (e.g., via stakes) for increased stabilization. Front panel locking assemblies 212 and 214 are provided on front panels 126 and 128. Front panel locking assemblies 212 and 214 engage side panels 116 and 118 at ends 122 and 124 to fix front panels 126 and 128 in place relative to side panels 116 and 118. Front panel locking assemblies 212 and are adjustable to different lengths to enable front panels 126 and 128 to be secured at one of multiple angular positions relative to side panels 116 and 118.

[0020] Each of front panels 126 and 128 may also include a retractable visual screen 215 mounted on their outermost sides as shown in Fig. 15. In one example, a vertically mounted roll up blind may be used as screen 215. Screen 215 includes latching mechanisms 217 (e.g., hooks) that connect to a stationary post 219 to hold screen 215 in an extended position to block a person's view beyond the outermost sides of front panel 128. In one example, latching mechanisms 217 may be used to connect screen 215 to a second visual screen mounted on a second mobile barrier system positioned in close proximity to system 100 to provide a continuous visual screen between the mobile barrier systems.

[0021] System 100 includes adjustable brace arms 216 and 218 that extend between side panels 116 and 118 and base 102 to secure side panels 116 and 118 in place in the deployed state. Arms 216 and 218 are adjustable to different lengths to enable side panels 116 and 118 to be secured at one of multiple angular positions relative to base 102. For example, brace arms 216 and 218 may include a telescoping slide mechanism including a hollow tubing member and complementary solid or hollow rod that fits inside and slides relative to the tubing member.
The tubing member and complementary rod may be fixed in place relative to each other at one- of multiple lengths via a locking mechanism (e.g., a pin and multiple longitudinally spaced-apart holes for receiving the pin, a ratcheting mechanism, a twist lock mechanism, a spring loaded mechanism). Other conventional locking mechanisms may be used to fix the brace arms 216 and 218 at one of multiple lengths. Each of brace arms 216 and 218 may release from one or more of its corresponding side panel and base 102 so that side panels 116 and 118 can be mobile barrier foreign application 69662/25:1 pivoted about hinges 120 to thereby transition from the deployed state to the compact transport state. In one example, brace arms 216 and 218 release from base 102 and are pivotably secured to side panels 116 and 118 so that the brace arms 216 and 218 may be folded adjacent to their corresponding side panels to allow the side panels 116 and 118 to be pivoted toward base 1.02.

[0022] Figs. 4 and 5 are top plan views of system 100 showing two different configurations in which arms 216 and 218 are at different lengths. In Fig. 4, arms 216 and 218 are at a length so that side panels 116 and 118 align with back panel 108 in a co-planar wall configuration. In Fig. 5, arms 216 and 218 are at a length so that side panels 116 and 118 form a V-shaped configuration. Other configurations for system 100 in the deployed state are contemplated. For example, Fig. 6 shows one application in which multiple mobile barrier systems 300, 400, 500, 600, 700, and 800 in different configurations are used together to provide security checkpoints for pedestrians and vehicles. Systems 300 and 400 are connected together via a connector positioned along abutting edges of their front panels, and each of systems 300 and 400 is in an L-shaped configuration in which one of its side panels is locked to its trailer base and the other side panel is secured in a substantially co-planar relationship with the back panel. Systems 500 and 600 are connected via connectors positioned along abutting edges of their front panels, and each of the systems 500 and 600 is in a U-shaped configuration in which both of its side panels are locked to the trailer base and the front panels align with the side panels. System 700 is in an L-shaped configuration and system 800 is in a co-planar wall configuration. Systems 700 and 800 are connected to each other via a connector positioned along abutting edges of their front panels.

[0023] As depicted in Fig. 7, system 100 includes retractable front anti-scaling panels 902 hinged to top portions of front panels 126 and 128, retractable side anti-scaling panels 904 hinged to top portions of side panels 116 and 118, and a retractable rear anti-scaling panel 906 hinged to a top portion of back panel 108.
Fig. 8 is a front elevation view of panels 902, 904, and 906 and Fig. 9 is a side elevation view of one of panels 902. Biasing mechanisms 908, such as gas springs, are positioned between each of the panels 902, 904, and 906 and its corresponding panel 108, 116, 118, 126, or 128 to assist movement of panels 902, 904, and mobile barrier foreign application 69662/25:1 between the deployed state and the compact transport state. In the deployed state depicted in Figs. 7, 8, and 9, panels 902, 904, and 906 extend upward from the top portions of panels 108, 116, 118, 126, and 128. Biasing mechanisms 908 allow panels 902, 904, and 906 to be secured at one of multiple angular positions relative to panels 108, 116, 118, 126, and 128 when in the deployed state. For example, panels 902, 904, and 908 angle toward base 102 when in the deployed state.

[0024] Fig. 10 is a perspective view of system 100 in a partly collapsed state during transitioning from the deployed state to the compact transport state, and Figs.
11 and 12 are perspective views of system 100 in the compact transport state.
To transition system 100 from the deployed'state to the compact transport state, rear anti-scaling panel 906 is lowered toward base 102 and side panels 116 and 118 are swung toward base 102 so that they run along opposing sides of base 102 as shown in Fig. 10. Side anti-scaling panels 904 are lowered toward base 102 and come together (i.e., the top edges of side anti-scaling panels 904 hinged to right side panel 116 may touch the top edges of side anti-scaling panels 904 hinged to left side panel 118 or a small gap or overlap may be formed between them). In one example, a gap in a range of about 0.5-2 centimeters (cm) may exist between opposite side panels 904. Side anti-scaling panels 904 may be at approximately right angles with respect to their corresponding side panel 116 or 118 so that side anti-scaling panels provide an approximately flat roof 915 for base 102 in the compact transport state.
Preferably, side anti-scaling panels 904 and rear anti-scaling panel 906 are configured so that side anti-scaling panels 904 overlap rear anti-scaling panel 906 wheh side anti-scaling panels 904 and rear anti-scaling panel 906 are in the compact transport state as shown in Fig. 12. Alternatively, rear anti-scaling panel 906 may overlap portions of side anti-scaling panels 904 in the compact transport state.

[0025] Front anti-scaling panels 902 are lowered toward base 102 and front panels 126 and 128 are swung toward each other to form a V-shaped pointed nose 920 for base 102 as shown in Fig. 11. Front edges of front panels 126 and 128 may, but need not, touch each other in the compact transport state. Rather, a gap may exist between the front edges of front panels 126 and 128 that is sufficiently small to avoid significant drag during travel. In one example, a gap between the front edges of front panels 126 and 128 may be relatively small so that system 100 is stable mobile barrier foreign application 69662225:1 enough for travel at or above highway speeds. In one example, the gap between the front edges of front panels 126 and 128 may be about 5 cm or less. Front anti-scaling panels 902 and 904 may be configured so that part of front anti-scaling panels 902 slide under side anti-scaling panels 904 when front panels 126 and are swung together. Alternatively, front-anti-scaling panels 902 may slide over the top of side anti-scaling panels 904 when front panels are swung together.
Front anti-scaling panels 902 include a trapezoid profile to provide clearance for front anti-scaling panels 902 when front panels 126 and 128 are swung together.

[0026] In the compact transport state, front panels 126 and 128 angle from side panels 116 and 118 at obtuse angles and form V-shaped nose 920 for base 102. V-shaped nose 920 and roof 915 may reduce drag for system 100 so that system 100 is relatively stable during travel at or above highway speeds. In the compact transport state, panels 108, 116, 118, 126, 128, 902, 904, and 906 form an envelope to cover base 102. Relatively small gaps may be present between the panels.
However, the envelope provided by panels 108, 116, 118, 126, 128, 902, 904, and 906 allows items stored on base 102 to be securely transported and helps to protect the items from vandalism and harsh weather conditions. Front panels 126 and are secured to a drawbar 916 of base 102 via locking mechanisms 918 shown in Fig.
1. In one example, locking mechanisms 918 include spring-loaded pin mechanisms attached to the side margins of front panels and receptacles secured to drawbar 916 for receiving the spring-loaded pin mechanisms. The receptacles may include flanges that overlie the spring-loaded pin mechanisms when engaged with the receptacles to thereby impede the spring-loaded pin mechanisms from becoming disengaged with the receptacles during travel over bumpy roads or rough terrain.
Moreover, front panels 126 and 128 may be locked together with a conventional lock (e.g., a padlock) to secure contents inside trailer base 102.

[0027] For increased stability in the compact transport state, system 100 may include a releasable link arm 924, shown in Fig. 10, extending between and connected to side panels 116 and 118 near ends 122 and 124. link arm 924 holds side panels 116 and 118 together in the compact transport state to inhibit side panels 116 and 118 from swinging open during transportation of system 100 even during travel at high speeds and/or over relatively rough terrain. In one embodiment, mobile barrier foreign application 69662/25:1 link arm 924 releases from one of side panels 116 and 118 after system 100 has been transported to allow side panels 116 and 118 to swing open to the deployed state. Once released, link arm 924 may swing toward the side panel 116 or 118 to which it is still connected to stow link arm 924 as shown in Fig. 1. In an alternative embodiment (not shown), link arm 924 includes two releasable segments, one connected to side panel 116 and the other connected to side panel 118, that are secured together via a lock in the compact transport state and that release from each other to allow side panels 116 and 118 to swing open.

[0028] In one embodiment, system 100 may include a ballistics lining 1002 as depicted in Figs. 13 and 14, to protect personnel from high-speed projectiles that may penetrate the wall panels. Ballistics lining 1002 may be secured to an inward side 1004 and/or an outward side 1006 of one or more panels 108, 116, 118, 126, 128, 902, 904, and 906. Preferably, ballistics lining 1002 is a relatively light-weight flexible fabric sheet made high impact strength fibers. In one example, ballistics lining 1002 is a flexible curtain that may be folded (e.g., drawn back) or rolled up and then extended to run along and cover one or more panels 108, 116, 118, 126, 128, 902, 904, and 906. Various types of high impact strength fibers may be used.
Suitable fibers include aramid fibers (e.g., KEVLAR brand fibers available from E.I.
du Pont de Nemours and Company, GOLD FLEX brand material available from Honeywell International, Inc., TWARON brand fibers available from Teijin Aramid BV located in Arnhem, Netherlands) and ultra-high-molecular-weight polyethylene fibers (e.g., DYNEEMA brand fibers available from Royal DSM N.V. located in Heerlen, Netherlands, SPECTRA brand fibers available from Honeywell International, Inc.). Ballistics lining 1002 may also include metal or ceramic plates such as those used in DRAGON SKIN body armor available from Pinnacle Armor located in Fresno, California.

[0029] Ballistics lining 1002 may span more than one panel. In one example, ballistics lining 1002 covers at least portions (e.g., abutting side edges) of side panel 116 and front panel 126. Moreover, ballistics lining 1002 may flex (e.g., fold) so that front panel 126 can swing relative to side panel 116 while ballistics lining 1002 is attached to side panel 116 and front panel 126. Thus, ballistics lining 1002 may mobile barrier foreign application 69662/25:1 cover multiple panels and remain attached to them as the panels are swung between the deployed state and the compact transport state.

[0030] Ballistics lining 1002 may be secured to one or more sides 1004 and of the panels using various types of fasteners. In one example, ballistics lining 1002 may be releasably attached to one or more panels 108, 116, 118, 126, 128, 902, 904, and 906 so that it can be detached from the panels and stowed (e.g., folded or rolled up and stored on base 102) when in the compact transport state.
Preferably, ballistics lining 1002 is securely attached to panels using high-strength VELCRO
brand fasteners 1008 (e.g., VELCRO brand MVA#8 molded hook tape) that make ballistics lining 1002 difficult to remove. In one example, a high-strength fastener is used to securely attach ballistics lining 1002 to outward side 1006 of one or more panels 108, 116, 118, 126, 128, 902, 904, and 906 to thereby impede unauthorized persons from removing or tampering with ballistics lining 1002. In another embodiment, panels 108, 116, 118, 126, 128, 902, 904, and 906 may include rigid sheets of ballistics material fixed to the frames of the panels.

[0031] It will be obvious to skilled persons that many changes may be made to the details of the above-described embodiments without departing from the underlying principles of the invention.

first and second side panels each having first and second opposing ends and a top portion, the first end of the first side panel being hinged along the first side margin of the back panel, the first end of the second side panel being hinged along the second side margin of the back panel, the first and second side panels operable to swing relative to the back panel to thereby move between the compact transport state and the deployed state, the first and second side panels running along and extending upward from opposing sides of the wheeled trailer base to form side walls thereof when in the compact transport state;

first and second front panels in which the first front panel is hinged along the second end of the first side panel and the second front panel is hinged along the second end of the second side panel, the first and second front panels operable to swing relative to the first and second side panels to thereby move between the compact transport state and the deployed state, each of the first and second front panels having a top portion; and a group of retractable anti-scaling panels hinged to the top portions of the back panel, the first and second side panels, and the first and second front panels, the retractable anti-scaling panels extending upward when in the deployed state and folding down toward the wheeled trailer base when moving from the deployed state to the compact transport state, the retractable anti-scaling panels corresponding to the first and second side panels configured to form an approximately flat roof for the wheeled trailer base when in the compact transport state, and the anti-scaling panels of the back panel and the first and second front panels being in an overlapping relationship with the retractable anti-scaling panels of the first and second side panels in the compact transport state to thereby overlie the wheeled trailer base.

14. The mobile barrier system of claim 13, wherein the anti-scaling panels, the back panel, the first and second side panels, and the first and second front panels form an envelope for the wheeled trailer base when in the compact transport state.

15. A mobile barrier system, comprising*
a wheeled trailer base having a front end from which a towing assembly extends for attachment to a towing vehicle;
a set of panels each moveable between a compact transport state and a deployed state in which the set of panels forms a barrier, the set of panels including-a back panel mounted to and extending upward from a back end of the wheeled trailer base, the back panel having first and second side margins;
first and second side panels each having first and second opposing ends, the first end of the first side panel being hinged along the first side margin of the back panel, the first end of the second side panel being hinged along the second side margin of the back panel, the first and second side panels operable to swing relative to the back panel to thereby move between the compact transport state and the deployed state, the first and second side panels running along and extending upward from opposing sides of the wheeled trailer base to form side walls thereof when in the compact transport state; and first and second front panels in which the first front panel is hinged along the second end of the first side panel and the second front panel is hinged along the second end of the second side panel, the first and second front panels operable to swing relative to the first and second side panels to thereby move between the compact transport state and the deployed state;
and a light-weight ballistics lining secured to one or more of the back panel, the first and second side panels, and the first and second front panels.

16. The mobile barrier system of claim 15, wherein the light-weight ballistics lining is flexible and is releasably secured to said one or more of the back panel, the first and second side panels, and the first and second front panels.

17. The mobile barrier system of claim 15, wherein the light-weight ballistics lining is made of a ballistics fabric and forms a curtain that runs along said one or more of the back panel, the first and second side panels, and the first and second front panels.
