The present disclosure generally relates to barrier systems and methods that provide for, among other things, traffic control on roadways.
Temporary road barrier systems allow for traffic control and general safety while, for example, a road undergoes construction. Such road barrier systems may generally include a number of road barrier segments positioned next to each another.
In an example, a barrier system is described. The barrier system includes a corner barrier segment. The corner barrier segment includes a central member, a first member coupled to the central member, and a second member coupled to the central member. The first member and the second member may be configured to rotate about an axis of the central member relative to each other. The first member includes a first fastener. The second member includes a second fastener. The system further includes a first barrier segment coupled to the first member via the first fastener on the first member of the corner barrier segment and a third fastener the first barrier segment. The system also includes a second barrier segment coupled to the second member via the second fastener on the second member of the corner barrier segment and a fourth fastener on the second barrier segment.
In another example, a method of configuring a system of road barriers is described. The method includes positioning a corner barrier segment in a first configuration, the corner barrier segment including a central member and first and second members which may rotate about an axis of the central member relative to each other. The first configuration defines a first angle between the first member and the second member about the central member. The method also includes rotating, about the axis of the central member, at least one of the first or the second member to position the corner barrier segment in a second configuration in which the first member and the second member define a second angle, which is different than the first angle. The method further includes coupling the first member of the corner barrier segment to a first barrier segment. The method also includes coupling the second member of the corner barrier segment to a second barrier segment.
The features, functions, and advantages that have been discussed can be achieved independently in various embodiments or may be combined in yet other embodiments further details of which can be seen with reference to the following description and drawings.
The novel features believed characteristic of the illustrative embodiments are set forth in the appended claims. The illustrative embodiments, however, as well as a preferred mode of use, further objectives and descriptions thereof, will best be understood by reference to the following detailed description of an illustrative embodiment of the present disclosure when read in conjunction with the accompanying drawings, wherein:
Disclosed embodiments will now be described more fully hereinafter with reference to the accompanying drawings, in which some, but not all of the disclosed embodiments are shown. Indeed, several different embodiments may be described and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are described so that this disclosure will be thorough and complete and will fully convey the scope of the disclosure to those skilled in the art. For instance, elements, arrangements, and functions may be added, removed, combined, distributed, or otherwise modified.
I. Overview
The barrier systems and methods of the present disclosure provide for road barrier and traffic control operations. Existing road barrier systems present a number of challenges. As an example, existing road barrier systems typically consist of several linear segments placed adjacent to one another. Using such existing road barrier systems, it can be challenging to traverse obstacles (e.g., a tree, a light post, a road sign, a traffic signal) along a path of the road barrier system. Additionally, for instance, it can be challenging to position road barrier segments along a curved portion of the path of the road barrier system. Specifically, existing systems can result in discontinuities and/or inefficient use of space and/or materials to traverse obstacles and/or position the road barrier system along a curved portion of a path of the road barrier system.
The systems and methods of the present disclosure can beneficially address, among other things, the challenge described above. Within examples, the systems and methods of the present disclosure provide for a barrier system including a corner barrier segment, which can improve the positioning of road barrier segments along a non-linear path and/or around obstacles in a desired path of the barrier system.
In one example, the systems and methods described in the present disclosure allow for a corner barrier segment to couple to at least two road barrier segments. The corner barrier includes a first member and a second member, which are rotatable about a central member relative to each other. Rotation of the first and second members allows for flexibility of the positioning of the two road barrier segments.
II. Example System
Referring to
As shown in
As described in further detail below, the first fastener 114 can couple the first member 110 to the first barrier segment 104. For example, the first fastener 114 can couple to a third fastener 118 of the first barrier segment 104 to couple the first member 110 to the first barrier segment 104. Similarly, the second fastener 116 can couple the second member 112 to the second barrier segment 106. For example, the second fastener 116 can couple to a fourth fastener 122 of the second barrier segment 106 to couple the second member 112 to the first barrier segment 104.
Additionally, as described in further detail below, the first member 110 and the second member 112 are rotatable, about an axis of the central member 108 relative to each other. As such, within examples, the first member 110 and the second member 112 of the corner barrier segment 102 can define an angle about the central member 108. In one example, the first member 110 and the second member 112 may define an angle about the central member 108 selected from a plurality of angles between approximately 30 degrees and approximately 330 degrees. In another example, the first member 110 and the second member 112 may define an angle about the central member 108 selected from a plurality of angles between approximately 90 degrees and approximately 270 degrees. By rotating the first member 110 relative to the second member 112, the corner barrier segment 102 can help to arrange the barrier system 100 around obstacles (e.g., a light post) and/or a non-linear portion of a path of the barrier system 100 (e.g., a curved portion of the path).
In one example, the corner barrier segment 102, the first barrier segment 104, and/or the second barrier segment 106 can be made from a polyethylene material. For instance, the polyethylene material can be in the form of a micro-granulate or powder having a density that is equal to or greater than approximately 0.935 grams per cubic centimeter. Additionally, for instance, the material can be thermally stabilized against ultraviolet (UV) radiation. Also, within examples, the material can have a stiffness with a Young's modulus that is greater than or equal to 645 megapascal (MPa) and a melt flow index (MFI) flow rate between approximately 1.0 gram per minute and approximately 8.0 grams per minute at a load of approximately 21.6 Newtons. Other materials having different characteristics may also be used in additional or alternative examples.
A. Example Corner Barrier Segments
Referring to
As shown in
In one example, the central member 208 can include a pin that extends along the axis 226. The first member 210 can include a first arm portion 211 defining a bore extending in the direction of the axis 226, and the second member 212 can include a second arm portion 213 defining a bore extending in the direction of the axis 226. In this arrangement, the pin of the central member 208 can extend through the bore of the first arm portion 211 and the bore of the second arm portion 213. In this way, the pin of the central member 208 can couple the first member 210 and the second member 212 such that the first member 210 and the second member 212 can rotate about the axis 226.
In an example embodiment, the central member 208 may be substantially cylindrical. However, the central member 208 can have a different shape in alternative examples. More generally, the central member 208 can have a shape that allows the first member 210 and the second member 212 to rotate about the axis 226 of the central member 208.
Within examples, the first member 210 can have a narrower width at the central member 208 and a wider width at a first lateral side 250 of the corner barrier segment 202 to assist with rotation of the first member 210 at the central member 208 and improve stability at the first lateral side 250. For instance, in
Similarly, the second member 212 can have a narrower width at the central member 208 and a wider width at a second lateral side 252 of the corner barrier segment 202 to assist with rotation of the first member 210 at the central member 208 and improve stability at the second lateral side 252. For instance, in
Although the first member 210 and the second member 212 each include a trapezoidal portion 240 and a triangular portion 242 in
Further, in some examples, an external surface on both the first member 210 and the second member 212 may define an internal cavity 221 such that the first member 210 and the second member 212 are hollow. The first member 210 and the second member 212 may also include one or more apertures 254, 256 in an upper portion of the first member 210 and the second member 212. As shown in
In general, the apertures 254, 256 provide access to the internal cavity 221 of the first member 210 and the second member 212 such that the first member 210 and the second member 212 can be filled with a fill material (i.e., the apertures 254, 256 can be used as a fill port). As examples, the fill material can include water, concrete, sand, a foam material (e.g., polyurethane foam), and/or gravel. In one implementation, the apertures 254, 256 can have a size and a shape that is configured to receive a standard concrete pump hose (e.g., the apertures 254, 256 can have a diameter of approximately 160 millimeters to receive a standard concrete pump hose). By receiving the hose of a system that supplies the fill material, the corner barrier segment 202 can beneficially reduce (or eliminate) splashing of the fill material onto the exterior of the corner barrier segment 202.
Within examples, the first member 210 and the second member 212 can each be a respective monolithic structure (e.g., made from a single part construction). This can help to mitigate (or prevent) distention of the first member 210 and/or the second member 212 while filling the corner barrier segment 202 with the fill material.
In some examples, the apertures 254, 256 may also each include a cap (not shown). In general, the caps can inhibit access to the internal cavities 221 of the first member 210 and the second member 212. In one implementation, the caps can provide a seal for the internal cavities 221 of the first member 210 and the second member 212 from an external environment. However, in other examples, one or more of the caps can cover the apertures 254, 256 without providing a seal.
As noted above, the corner barrier segment 202 is configured such that the first member 210 can rotate, about the axis 226, relative to the second member 212. Accordingly, the corner barrier segment 202 can be arranged in a plurality of configurations in which the first member 210 and the second member 212 define respective angles about the central member 208.
As shown in
As shown in
Within examples, a corresponding fastener on an adjacent barrier segment (e.g., the third fastener 118 of the first barrier segment 104) can extend into the recessed portion 251 of the first lateral side 250. This can help to reduce a gap between first lateral side 250 of the corner barrier segment 202 and the adjacent barrier segment when coupled to each other. For instance, in one implementation, the adjacent barrier segment can include corresponding loops that overlap with the loops 255 of the first fastener 214 to define an eye through which the bolt 249 can be inserted to couple the corner barrier segment 202 to the adjacent barrier segment. Additionally, for example, the top groove 253A and the bottom groove 253B can abut against similar grooves of the adjacent barrier segment to define a passage for inserting the bolt 249 through the loops 255.
As shown in
Within examples, a corresponding fastener on an adjacent barrier segment (e.g., the fourth fastener 122 of the second barrier segment 106) can extend into the recessed portion 251 of the second lateral side 252. This can help to reduce a gap between second lateral side 252 of the corner barrier segment 202 and the adjacent barrier segment when coupled to each other. For instance, in one implementation, the adjacent barrier segment can include corresponding loops that overlap with the loops 255 of the second fastener 216 to define an eye through which the bolt 249 can be inserted to couple the corner barrier segment 202 to the adjacent barrier segment. Additionally, for example, the top groove 253A and the bottom groove 253B can abut against similar grooves of the adjacent barrier segment to define a passage for inserting the bolt 249 through the loops 255.
Although the first fastener 214 and the second fastener 216 can include the loops 255 and be coupled to an adjacent barrier segment by the bolt 249, the first fastener 214 and/or the second fastener 216 can additionally or alternatively include non-loop type fasteners and/or be coupled to the adjacent barrier segment by means other than the bolt 249 in other examples. For example, as described further below, the first fastener 214 and/or the second fastener 216 can include one or more hooks that couple with corresponding loops. Additionally or alternatively, the loops 255 of the first fastener 214 and/or the second fastener 216 can be coupled with corresponding hooks on the adjacent barrier segment(s) instead of the bolt 249 in other examples. In one implementation, the loops 255 can be formed from S235JR steel and/or treated (e.g., coated) with a layer of anti-corrosion material.
In some examples, the first fastener 214 and/or the second fastener 216 can be permanently affixed to the first member 210. For instance, the first fastener 214 and/or the second fastener 216 can be coupled to the corner barrier segment 202 by, for example, one or more welds, screws, and/or bolts. In
In another example, the first fastener 214 and/or the second fastener 216 can be removably coupled to the corner barrier segment 202 by, for instance, a threaded connection on the first lateral side 250 of the first member 210 and/or the second lateral side 252 of the second member 212. Further, in some examples, the first fastener 214 and/or the second fastener 216 can each include a single fastener. In other examples, the first fastener 214 and/or the second fastener 216 can each include a plurality of fasteners.
In one example, the bolt 249 can be a ribar structure. Also within examples, the bolt 249 can include a protective covering 257 on a top end of the bolt 249. For instance, the protective covering 257 can be made from a foam material to protect the bolt.
B. Example First and Second Barrier Segments
Within examples, the corner barrier segment 202 can be coupled to a variety of different first barrier segments 104 and/or second barrier segments 106. The following is a description of example barrier segments that can be coupled to the corner barrier segment 202 within examples. However, additional or alternative barrier segments are further illustrated and described below with respect to
Referring to
As shown in
The first barrier segment 304 can include one or more upper channels 330 at the upper portion of the first barrier segment 304. In an example, the upper channels 330 can help to protect the first barrier segment 304 against bloating while filling the first barrier segment 304 with the fill material. For instance, in one implementation, a threaded rod can be placed in each upper channel 330 and nuts can be screwed onto opposing ends of the threaded rod. As the fill material is supplied to the internal cavity 321, the threaded rods (secured by the nuts) in the upper channels 330 can help to mitigate (or prevent) bloating as a result of the internal pressure applied by the fill material on the walls of the first barrier segment 304. Also, within examples, the upper channels 330 can provide structures for coupling equipment such as, for example, reflector lights and/or signs.
As shown in
Within examples, the first barrier segment 304 can each be a monolithic structure (e.g., made from a single part construction). This can help to mitigate (or prevent) distention of the first barrier segment 304 while filling the first barrier segment 304 with the fill material.
Additionally, as shown in
The third fastener 318 of the first barrier segment 304 can be coupled to the first end 358 of the first barrier segment 304, and the fifth fastener 320 on the first barrier segment 304 can be coupled to the second end 360 of the first barrier segment 304 in a manner similar to that described above with respect to
As noted above, the first barrier segment 304 can include one or more apertures 328 in the upper portion of the first barrier segment 304. Additionally, as noted above, the apertures 328 provide access to the internal cavity 321 of the first barrier segment 304 such that the first barrier segment 304 can be filled with a fill material (i.e., the aperture 328 can be used as a fill port). As illustrated in
Within examples, equipment can be positioned in one or more of the apertures 328 such that the equipment extends from the internal cavity 321 of the first barrier segment 304 to an external environment. In one example, the equipment can be coupled to the fill material in the internal cavity 321 to assist in stabilizing the equipment on the first barrier segment 304. Equipment may include, for example, any combination of one or more of an atmospheric detection device (e.g., measuring an amount of exhaust gases), a radar detection device, a vehicle counting device, or a road traffic control device (e.g., a stop sign, a traffic light, a construction sign, a traffic sign, etc.). Many other examples of equipment are possible.
In examples where the first barrier segment 304 is attached to the first member 210 via the first fastener 214 and the third fastener 318, rotation of the first member 210 about an axis 226 of the central member 208 affects placement of the first barrier segment 304 within the road barrier system 100. Additionally, this may affect placement any other barrier segments attached to the first barrier segment 304 in the road barrier system 100. For example, the corner barrier segment 202 may be in a first configuration where the first member 210 and the second member 212 define a first angle 234 about the central member 208. The first member 210 may be rotated to a second configuration defining a second angle 236, different from the first angle 234, about the central member 208. This is can help arrange the road barrier system 100 around obstacles (e.g., a light post, a traffic sign, a tree, etc.).
Further, regarding the shape of the first barrier segment 304, the lower portion of the first barrier segment 304 may be wider than the upper portion of the first barrier segment 304. The wider lower portion can help provide stability to the first barrier segment 304.

As shown in
Additionally, the first end 458 of the second barrier segment 406 may be a first height and the second end 460 of the second barrier segment 406 may be a second height which is lesser than the height of the first end 458 (i.e., the top portion 444 of the second barrier segment 404 is sloped from the first end 458 to the second end 460). Furthermore, in some examples, an external surface on the second barrier segment 406 may define an internal cavity 421 such that the second barrier segment 406 is hollow.
In some example embodiments, the second barrier segment 406 may include one or more upper channels 406A near an upper portion of the second barrier segment 406. The upper channels may extend from a first end 458 of the second barrier segment 406 to a second end 460 of the second barrier segment 406. In some examples, the upper channels 406A may be substantially rectangular. Alternatively, the upper channels 406A may be substantially cylindrical. Many other examples are possible.
The second barrier segment 406 may also include one or more apertures 428 in an upper portion of the second barrier segment 406. In example embodiments, the apertures 428 provide access to the internal cavity of the second barrier segment 406 such that the second barrier segment 406 may be filled with a fill material (i.e., the apertures 428 can be used as a fill port). As shown in
Additionally or alternatively, equipment may be placed in the aperture or apertures 428 such that the equipment extends from the internal cavity of the second barrier segment 406 to an external environment. In one example, the equipment can be coupled to the fill material in the internal cavity to assist in stabilizing the equipment on the second barrier segment 406. Equipment may include, for example, any combination of one or more of an atmospheric detection device, a radar detection device, a vehicle counting device, or a road traffic control device (e.g., a stop sign, a traffic light, a construction sign, etc.). Many other examples of equipment are possible.
Additionally, the second barrier segment 406 may include one or more recessed pockets 432 at a lower portion of the first lateral side 462 of the second barrier segment 406 and/or the second lateral side 464 of the second barrier segment 406. In some examples, the recessed pocket(s) 432 may be substantially rectangular or trapezoidal near the exterior surface of the second barrier segment 406. Additionally, the recessed pocket 432 may be narrower near the center of the second barrier segment 406 (i.e., the back of the recessed pocket 432). The recessed pockets 432 can help prevent distention of the second barrier segment 406 while the second barrier segment 406 is filled with fill material. Further, the recessed pockets 432 can help drain excess water or snow from a road way.
Within examples, the second barrier segment 406 can each be a monolithic structure (e.g., made from a single part construction). This can help to mitigate (or prevent) distention of the second barrier segment 406 while filling the second barrier segment 406 with the fill material.
In examples where the second barrier segment 406 is attached to the second member 212 via the second fastener 216 and the fourth fastener 422, rotation of the second member 212 about an axis 226 of the central member 208 affects placement of the second barrier segment 406 within the road barrier system 100. Additionally, this may affect placement of other barrier segments coupled to the second barrier segment 406 in the road barrier system 100. For example, the corner barrier segment 202 may be in a first configuration where the first member 210 and the second member 212 define a first angle 234 about the central member 208. The first member 210 may be rotated to a second configuration defining a second angle 236, different from the first angle 234, about the central member 208. This is can help arrange the road barrier system 100 around obstacles (e.g., a light post, a traffic sign, a tree, etc.).
The top portion 444 of the second barrier segment 404 may be sloped from the first end 458 to the second end 460. The sloped second barrier segment 404 can help reduce severity of the impact of a car colliding with the second barrier segment 404.
In the examples described previously, the first barrier segment 304 is a non- sloped segment and the second barrier segment 406 is a sloped segment. Many other arrangements and configurations are possible. For example, both the first barrier segment 304 and the second barrier segment 406 may be sloped segments. Alternatively, both the first barrier segment 304 and the second barrier segment 406 may be non-sloped segments.

In examples in which a barrier segment includes two or more fasteners on a lateral side, the fasteners may be of the same type or different types. Additionally, a barrier segment can have the same type or different types of fasteners on the lateral sides. For instance, the third fastener 318 on the first end 358 of the first barrier segment 304 may be a hook fastener 684 and the fifth fastener 320 on the second end 360 of the first barrier segment 304 may be a receptacle fastener 682. Alternatively, for example, both the third fastener 318 and the fifth fastener 320 may be hook fasteners 684.
