FIELD OF THE DISCLOSURE

[0002] The present disclosure relates generally to supporting one or more upright items from a support surface.

BACKGROUND

[0003] Temporary or semi-permanent support surfaces and other components have been used for roadways, remote jobsites, industrial staging areas and the like in an ever-increasing myriad of industries, such as the construction, military, oilfield, transportation, disaster response, utilities and entertainment industries. It is sometimes necessary or desirable to provide one or more upright items in connection with the support surface. A few examples of upright items that, depending upon the particular scenario and application, may be used in connection with support surfaces are signs, fences, safety barriers, markers, road reflectors, warning sirens, beacons or other lights or other accessories, or a combination thereof. As used herein, the terms "upright member" and variations thereof mean any item or combination of items desired to be visible or audible from a particular location on a support surface.

[0004] In some applications and use scenarios, the upright item should be able to withstand some amount of forces applied to them. For example, in some instances, the forces may be wind forces. For another example, the forces may be leaning loads, such as the forces of personnel leaning on a safety barrier. If desired, the upright item may be designed to satisfy regulatory or other load-bearing standards or requirements, such as OSHA's proscribed load target(s) for supporting leaning loads. Thus, there is a need for improved apparatus, systems and methods for supporting upright items from a support surface.

[0005] It should be understood that the above-described features and capabilities are provided for illustrative purposes only and are not intended to limit the scope or subject matter of the appended claims or those of any related patent application or patent. Thus, none of the appended claims or claims of any related application or patent should be limited by the above discussion or construed to address, include or exclude each or any of the above-cited features or capabilities merely because of the mention thereof herein.

[0006] Accordingly, there exists a need for improved systems, articles and methods for supporting one or more upright items from a support surface having one or more of the attributes or capabilities described or shown in, or as may be apparent from, the other portions of this disclosure.

However, in some instances of the use of the terms "generally", "substantially" and variations thereof herein, the above definition may not apply, as should be apparent from the context of such use.

[00057] Referring initially to Figures 1 and 2, an exemplary support surface 16 having at least one panel or mat 26 deployed on or near the ground 20 is shown. As used herein, the term "ground" and variations thereof mean the earth' s surface, and/or other one or more other surfaces, structures or areas proximate to or associated with the earth's surface. In the present embodiment, the support surface 16 is reusable and capable of supporting the weight of people, vehicles, equipment and/or other structures thereupon. The illustrated support surface 16 includes at least two interconnected adjacent mats 26.

[00058] The mats 26 may have any suitable form, construction, components, configuration and operation. Some examples of mats 26 which may be used in various embodiments of the present disclosure are shown and described in in U.S. Patent Numbers 5,653,551 to Seaux, entitled "Mat System for Construction of Roadways and Support Surfaces" and issued on August 5, 1997, and 6,511,257 to Seaux et al., entitled "Interlocking Mat System for Construction of Load Supporting Surfaces" and issued on January 28, 2003, both of which have a common Assignee as the present patent application and the entire contents of which are hereby incorporated by reference herein in their entireties. For example, each exemplary mat 26 may weigh approximately 1,000 lbs., be designed to withstand up to 600 psi in pure crush pressure placed thereupon, reduce point-to-point ground pressure on the ground 20 that may be caused by wheeled and/or tracked vehicles on the mat 26 or a combination thereof. In some embodiments, the mats 26 may be 14' x 8' DURA-BASE® mats currently sold by the Assignee of this patent application. As used herein and in the appended claims, the term "mat" and variations thereof includes and incorporates a mat, panel or other component of a support surface. [00059] If desired, the support surface 16 may be used in connection with any of the components and features described and shown in U.S. Patent Number 9,132,996 issued on September 15, 2015 to Robertson and entitled "Crane-Mounted Grab Head", U.S. Patent Number 9,297, 124 issued on March 29, 2016 and entitled "Methods of Moving at Least One Mat With a Crane-Mounted Grab Head", U.S. Patent Number 7,370,452 issued on May 13, 2008 to Rogers and entitled "Mat Assembly for Heavy Equipment Transit and Support", U.S. Patent Number 9,039,325 issued on May 26, 2015 to McDowell and entitled "Liquid Containment System for Use with Support Surfaces", U.S. Patent Application Serial Number 14/720,799, filed on May 24, 2015 and entitled "Liquid Containment System", U.S. Patent Application Serial Number 14/336,163, filed on July 21, 2014 and entitled "Apparatus and Methods for Providing Illuminated Signals from a Support Surface", U.S. Patent Application Serial Number 14/496, 105, filed on September 25, 2014 and entitled "Apparatus & Methods for Electrically Grounding a Load-Supporting Support Surface", U.S. Patent Application Serial Number 14/838,064, filed on August 27, 2015 and entitled "Apparatus & Methods for Electrically Grounding a Load-Supporting Support Surface", U.S. Provisional Patent Application Serial Number 62/246,687, filed on October 27, 2015 and entitled "System, Apparatus, Compositions and Methods for Enhancing Fire Resistance of Load-Supporting Surfaces", each of which has a common Assignee as the present patent application and the entire contents of which are hereby incorporated by reference herein in their entireties.

[00060] Still referring to Figures 1 and 2, in the illustrated embodiment, each mat 26 is flat, or planar, heavy duty, durable and all-weather. The exemplary mats 26 are reusable and interlock together to form at least part of the support surface 16. Each illustrated mat 26 has a stepped-configuration and is constructed of impermeable material, such as thermoplastic. As used herein, the terms "stepped-configuration" and variations thereof mean the mat 26 has at least one portion that extends at least partially on a different plane than at least one other portion and the planes are at least substantially parallel. Other example mats 26 may be constructed entirely or partially of wood, steel, steel-framed wood, aluminum, rubber, plastic, fiberglass, fiber reinforced plastic, recycled rubber or materials or any other desired material or combination thereof.

[00061] Referring specifically to Figure 1, the illustrated mat 26 has a rectangular shape with an opposing pair of short sides 28, 30, an opposing pair of long sides 37, 38, and at least one edge 44 (e.g. edge 44a) extending along each side 28, 30, 37 and 38 and around a perimeter 114 (e.g. perimeter 114a) of the mat 26. In this particular example, the mat 26 is constructed of upper and lower engaged offset panels 106, 108 and is reversible. In other words, the top and bottom of the illustrated mat 26 are mirror images of one another, so either the top or bottom can be facing up or down and interconnected with other mats or other components of a support surface 16. The illustrated mat 26 thus has a first, upper, set of aligned edges 44a extending around an "upper" perimeter 114a (formed around the upper panel 106), and a second, lower, set of aligned edges 44b extending around a "lower" perimeter 114b (formed around the lower panel 108). However, in other embodiments, the mat 26 may be a single unitary item or a combination of more than two component parts, may not be reversible, may have only one, or more than two, perimeters 114, or any desired combination thereof.

[00062] In this example, the first short side 28 and first long side 37 each have an upper lip 46 extending horizontally outwardly therefrom, which will typically be spaced above the ground 20. The illustrated second short side 30 and second long side 38 each have a lower lip 54 extending horizontally outwardly therefrom, and which will typically rest on the ground 20. Thus, in this embodiment, two sets of aligned edges 44a, 44b are formed around the sides 28, 30, 37 and 38. [00063] The upper and lower lips 46, 54 may have any suitable size, shape, configuration and length. It should be understood, however, that the present disclosure is not limited to use with the above-described embodiments of mats 26 having upper and/or lower lips 46, 54 or a stepped-configuration. For example, the embodiments of an upright member support system 300 as described below may be used in connection with mats 26 not having upper and/or lower lips 46, 54 or a stepped-configuration.

[00064] Referring back to Figures 1 & 2, many temporary or semi-permanent support surfaces have holes, or cut-outs, 32 formed in them. For example, support surfaces 16 made up of multiple mats, panels and/or other components often include connecting holes 32 formed therein. In some instances, the mats, panels and/or other components include holes 32 that can be aligned over or under those of adjacent mats/panels/components and through which removable locking pins 34 are inserted for connecting the mats/components together. These sorts of holes 32 are sometimes referred to herein as "locking pin" holes.

[00065] In the illustrated example, the respective upper and lower lips 46, 54 of different mats 26 are interconnectable with locking pins 34 releasably securable through corresponding locking pin holes 32 formed therein. The locking pin holes 32 and locking pins 34 may have any suitable form, construction, configuration, components and operation. In this embodiment, the illustrated mats 26 include a plurality of locking pin holes 32, each configured to accept a releasable locking pin 34 therethrough. Each illustrated mat 26 may include, for example, a total of sixteen locking pin holes 32, eight locking pin holes 32 formed in each set of upper and lower lips 46, 54. However, the present disclosure is not limited to use with mats or other support surface components having "locking pin" holes, but can be used with mats or other support surface components having any suitable orifice, opening, hole or cut-out formed therein. Thus, as used herein, the terms "hole" and variations thereof mean any hole, opening, orifice or cut-out formed in a mat, panel or other component of a support surface, having any desired shape, location, configuration and form and suitable for use in connection with an upright member support system in accordance with the present disclosure.

[00066] Some examples of locking pins 34 which may be used in various embodiments of the present disclosure are shown and described in U.S. Patent Number 6,722,831 to Rogers et al., entitled "Fastening Device" and issued on April 20, 2004, U.S. Patent Number 8,388,291 to Rogers, entitled "Mat Lock Pin" and issued on March 5, 2013, U.S. Patent Number 9,068,584 to McDowell et al, entitled and "Apparatus & Methods for Connecting Mats" and issued on June 30, 2015, U.S. Provisional Patent Application Serial Number 62/216,542, entitled "Apparatus for Connecting Mats and/or Other Components and Methods of Assembly and Use Thereof and filed on September 10, 2015, each of which has a common Assignee as the present patent application and the entire contents of which are hereby incorporated by reference herein in its entirety.

[00067] In some embodiments, the locking pins 34 may form a fluid-tight seal around, or in, the locking pin holes 32 within which they are engaged, such as the exemplary locking pin 34 illustrated and described in U.S. Patent Number 9,068,584, U.S. Provisional Patent Application Serial Number 62/216,542, entitled "Apparatus for Connecting Mats and/or Other Components and Methods of Assembly and Use Thereof and filed on September 10, 2015 and U.S. Patent Application Serial No. 14/752,067 entitled "Adjustable Mat Locking Pin and Methods of Use Thereof and filed on June 26, 2015, all of which have a common Assignee as the present patent application and the entire contents of which are hereby incorporated by reference herein in their entireties.

[00068] Referring to Figures 3 A & 3B, the illustrated locking pin holes 32 of the mats 26 have a non-circular cross-sectional shape. In this example, the locking pin holes 32 have an oval shape, such as to accept an oval-shaped enlarged head 36 of the illustrated locking pins 34. An oval-shaped recess, or indentation, 33 is formed in the upper and lower surfaces 27, 29 of each exemplary mat 26 around each locking pin hole 32. In this embodiment, the indentation 33 is also oval and configured to at last partially seat the oval-shaped enlarged head 36 of the illustrated locking pin 34.

[00069] As shown in Figure 4C, in some embodiments, the upper and lower surfaces 27, 29 of the mat 26 may include raised traction promoting elements, or treads, 31 formed in or extending from the mat 26. However, in some stepped-configuration embodiments, the treads 31 may not be included on the underside of each panel 106, 108 of the mat 26 that extends beyond the other respective panel 106, 108. In other words, in the illustrated mat 26, the upper surface 27 of the mat 26 that forms the lower lip 54 (which is the portion of panel 108 that extends beyond panel 106) is absent the treads 31. Thus, the locking pin holes 32 on the exemplary upper lip 46 are surrounded by treads 31, while the locking pin holes 32 on the illustrated lower lip 54 are not surrounded by treads 31. Of course, when the same mat 26 is turned over, the former lower lip 54 (absent treads 31) becomes an upper lip 46 having treads 31. Some exemplary raised traction promoting elements that may be used on the mats 26 in some embodiments are shown and described in U.S. Patent No. 6,511,257.

[00070] It should be noted, however, that the present disclosure is not limited to use with the above-described or referenced types and configurations of support surfaces 16, mats 26, locking pins 34 and holes 32, or to the disclosures of the above-referenced patents and patent applications. Any suitable support surfaces, mats and holes may be used.

[00071] Referring back to Figure 2, in some embodiments, a gap 22 may be formed between adjacent edges 44 of adjacent interconnected mats 26 in the support surface 16, and one or more seal members 10 may be included therein. For example, the seal member(s) 10 may provide a liquid-tight seal in the gap 22 between adjacent mats 26 to prevent liquid introduced onto the support surface 16 from seeping or flowing between mats 26 and/or other components and below the support surface 16.

[00072] Some embodiments of seal members 10 that may be used in the gaps 22 are disclosed in U. S. Patent No. 9,212,746 to McDowell, issued on December 15, 2015 and entitled "Apparatus and Methods for Sealing Between Adjacent Components of a Load- Supporting Surface", U. S. Patent Application Serial Number 14/948,340, filed on November 22, 2015 and entitled "Method of Sealing Between Adjacent Components of a Load- Supporting Surface With at Least One Closed-Cell Compressible Rubber Seal", U. S. Patent Application Serial Number 14/730,938, filed on June 4, 2015 and entitled "Load-Supporting Surface with Actively Connected Gap Seals and Related Apparatus and Methods", and U.S. Patent Application Serial Number 14/733,324, filed on June 8, 2015 and entitled "Load- Supporting Surface with Interfacing Gap Seal Members and Related Apparatus and Methods", all of which have a common Assignee as the present patent application and the entire contents of which are hereby incorporated by reference herein in their entireties.

[00073] The support surface 16 may include or be associated with other components, and the seal member(s) 10 may also or instead be used between any combination of mats 26 and other components associated with the support surface 16. Some examples of such additional components that may be useful in connection with support surfaces 16, such as berm members, spacers, drive-over barriers, liquid drain assemblies, etc., are shown and disclosed in U.S. Patent 9,039,325 and U.S. Patent Application Serial Number 13/790,916.

[00074] In some instances, such as shown in Figure 4A, the support surface 16 may be used around an underground borehole 120, such as with the use of a borehole edge seal system 110. Various embodiments of exemplary borehole edge seal systems 110 are shown and described in U.S. Patent Application Serial Number 14/497,429, entitled "Apparatus and Methods for Sealing Around the Opening to an Underground Borehole" and filed on September 26, 2014 and U.S. Patent Application Serial Number 14/666,584 entitled "Apparatus and Methods for Mechanically Coupling a Sealing System Around the Opening to an Underground Borehole" and filed on March 24, 2015, both of which have a common Assignee as the present patent application and the entire contents of which are hereby incorporated by reference herein in their entireties.

[00075] In various embodiments, such as shown in Figure 4B, one or more electrically- conductive covers 115 may be used in connection with the support surface 16. Various embodiments of electrically-conductive covers are shown and described in U.S. Patent Application Serial Numbers 14/496, 105 and 14/838,064. If desired, one or more illuminators (not shown) may be used in connection with the support surface 16. Various embodiments of illuminators are shown and described in U.S. Patent Application Serial Number 14/336,163.

[00076] However, it should be understood that none of the particular embodiments or features described or shown in Figures 1-4C, or in the above-referenced patents and patent applications, is required for, or limiting upon, the present disclosure unless and only to the extent as may be explicitly required in a particular claim hereof or in a patent claiming priority hereto and only for such claim and any claims depending therefrom.

[00077] Now referring to Figures 5A-C, an embodiment of an upright member support system 300 for supporting at least one upright member 310 from the support surface 16 is shown. The upright member 310 with which the support system 300 may be used may have any desired components, configuration, operation and use. For example, the upright member 310 may be, or include, a bar, post, frame or the like. In this embodiment, the upright member 310 is a pole 312 useful to support one or more signs, fences or safety barriers, and may be constructed of any suitable material, such as aluminum, steel or fiberglass. In Figure 12, for example, multiple upright member support systems 300 are shown supporting multiple poles 312 which are part of a safety barrier system 420. For another example, Figure 13 shows multiple upright member support systems 300 each supporting an upright member 310 that carries a sign 418. However, the present disclosure is not limited to these exemplary types of upright members 310. In fact, the support system 300, present disclosure and appended claims are not intended to be limited by the type, function or any other characteristics of the upright member 310.

[00078] As shown, the exemplary support system 300 positions the upright member 310 to extend vertically upwards from the mat 26. In other embodiments, the system 300 could position the upright member 310 to extend angularly upwards from the mat 26, sideways or in another orientation. As used herein and in the appended claims, the phrases "extending from", "upright", "upwardly" and variations thereof when used in the context of the relationship of the upright member (e.g. 310) relative to the support surface (e.g. 16) means extending therefrom in any direction other than downwardly into the ground 20. Thus, the present disclosure is not limited by the particular orientation of the upright member 310 relative to the support surface 16, as long as the support system 300 supports the upright member 310 relative to the support surface 16 in a direction other than down into the ground 20.

[00079] As shown in Figure 5B, the illustrated support system 300 includes at least one elongated carrier 320 (See also Figures 6A-C). As used herein, the terms "elongated" and variations thereof mean an item having an overall length that is greater than its average width. The exemplary carrier 320 engages the upright member 310 and the support surface 16, and assists in supporting the upright member 310 as it extends from the support surface 16.

[00080] The carrier 320 may have any suitable form, configuration, components, construction and operation and may engage the upright member 310 and support surface 16 in any suitable manner. In this embodiment, as shown in Figures 7A-E, the carrier 320 includes a threaded upper end 322, a lower end 324 and at least one longitudinally-oriented bore 326. In this example, as shown in Figure 7A, the bore 326 extends into the carrier from one or more openings 332 formed in the upper end 322 of the carrier 320 to an internal surface 330 (e.g. Figure 7C) located proximate to the lower end 324. In other embodiments, one or more internal surfaces 330 may be located elsewhere, angled or not included. The illustrated bore 326 is configured to (i) receive at least part of the upright member 310 which, in this embodiment, is slideable therein, and (ii) hold the upright member 310 it its desired upright position relative to the support surface 16.

[00081] As shown in Figures 5B and 5G, the lower end 324 of the illustrated carrier 320 is releasably engageable with the support surface 16. For example, at least part of the lower end 324 is insertable into and through at least one hole 32 of the illustrated mat 26 and releasably securable to the mat 26. In this embodiment, the lower end 324 is shown is engaged with the "locking pin" hole 32 of the upper lip 46 of the illustrated mat 26. In other embodiments, the lower end 324 may be engaged with the locking pin hole 32 of a mat's lower lip 54, a hole 32 in another part of the mat 26, or aligned holes 32 of multiple mats 26 and/or other components.

[00082] Any suitable arrangement for engaging the lower end 324 of the carrier 320 to the mat 26 may be used. Referring back to Figures 7A-C, for example, the lower end 324 may include a neck portion 334 that is rotatable within the hole 32 of the mat 26 (e.g. Figure 5B), and at least one coupler 336 situated below the neck portion 334 and configured to extend through the hole 32 and engage the mat 26. The neck portion 334 and coupler 336 may have any suitable form, configuration and operation. In this example, the neck portion 334 has a cross-sectional shape (e.g. circular) so that when the neck portion is positioned in the exemplary (e.g. non-circular shaped) hole 32, the lower end 324 of the carrier 320 is freely rotatable relative to the hole 32. The exemplary coupler 336 includes at least one foot 340 having at least two protrusions, or toes, 344 extending laterally outwardly therefrom and configured to be insertable through the hole 32 of the mat 26 (or another component or multiple aligned mats and/or other components) of the support surface 16 in at least a first position of the lower end 324 of the carrier 320. When the exemplary lower end 324 is (at least partially) rotated into at least a second position, the exemplary toes 344 are configured to extend below and outwardly relative to the hole 32 of the mat 26. (See also, e.g. Figure 5G). For example, each ninety-degree rotation of the illustrated carrier 320 moves the exemplary toes 344 between positions.

[00083] In the second, or locked, position of the lower end 324, as shown in Figure 5G, the exemplary toes 344 are misaligned with the hole 32, preventing the lower end 324 from being removed from the hole 32 and the carrier 320 from being disengaged from the mat 26. For example, the illustrated toes 344 are shown engaging the recess 33 formed in the lower surface 29 of the mat 26 around the hole 32. (In Figures 6A-C, the toes 344 are also shown in the locked position relative to the mat 26.) In other embodiments, the toes 344 may engage the lower surface 29 of the mat 26 itself, another portion of the mat 26 or other component of the support surface 16 adjacent to the hole 32.

[00084] If desired, the foot 340 may be formed, configured and operate similarly as the foot (e.g. foot 66) described and illustrated in U.S. Patent No. 9,068,584 and U.S. Patent Application Serial No. 14/752,067. While the foot 66 of U.S. Patent No. 9,068,584 and App. Serial No. 14/752,067 is particularly described as being inserted through the connecting holes 18 of two mats 12, 14, the foot 340 of the present disclosure may be similarly inserted through one or more holes 32 of one or more mats 26 or other components. However, the lower end 324 of the carrier 320 may be secured to the mat 26, another component of the support surface 16 or a combination of multiple mats 26/other components in any other suitable manner. [00085] Referring back to Figures 5A-C, the illustrated upright member support system 300 also includes at least one releasable base 350 arranged and adapted to extend at least partially around at least part of the lower end 324 of the carrier 320 and rest upon, abut or engage the support surface 16 (or any other component, intermediate surface or material disposed atop the support surface 16). If desired, the base 350 may be configured to assist in transferring load from the carrier 320 to the mat 26 and/or for any other desired purpose(s).

[00086] The base 350 may have any suitable form, configuration, components, construction and operation. Referring to Figures 8A-E, in this embodiment, the base 350 includes a longitudinally-oriented bore 354 extending therethrough to allow the base 350 to be slid over the top of the carrier 320 from the upper end 322 thereof and down the carrier 320 until it at least partially surrounds at least part of the lower end 324 thereof above the mat 26 (See e.g. Figures 5B & 6C). If desired, as shown in Figures 8B & C, the base 350 may include at least one longitudinally-oriented receiving slot 358 formed therein and extending at least partially along the length of, and in communication with, the bore 354. For example, when included, each exemplary slot 358 may be configured to mate with or receive at least one distinct alignment rib 338 extending outwardly from the carrier 320 along at least part of its length (e.g. Figures 7A-C) when the base 350 is positioned over the lower end 324 of the carrier 320. This slot 358/rib 338 arrangement may be included, for example, to assist in preventing, limiting or reducing rotation of the carrier 320 relative to the support surface 16, stabilizing the upright member support system 300 and upright member 310 or any other desired purpose. The present embodiment includes, for example, three sets of slideably mating elongated alignment ribs 338 and elongated slots 358. However, any desired number of alignment ribs 338 and receiving slots 358 may be used.

[00087] Still referring to Figure 8A-E, the base 350 may have any suitable shape and purpose. For example, the illustrated base 350 may be configured to abut, and transfer load placed upon the carrier 320 to, the face or upper surface 27 of the mat 26 (e.g. Figures 5B & C) (or any other component, intermediate surface or material disposed atop the mat 16) and/or reduce the bending moment of the carrier 320. Thus in the context of the relationship of the base 350 and the mat 26, as used herein and in the appended claims the phrase "upper surface" of the mat 26 includes and encompasses the upper surface 27 of the mat 26 and any other component, material or intermediate surface disposed atop the mat 16. In this embodiment, the base 350 has a conical outer shape with four perimeter corners 360 configured to transfer and spread load from the carrier 320 to different points or areas on the upper surface 27 of the mat 26 (e.g. Figures 5B & C). In other embodiments, the base 350 may include two or more (e.g. three, four, five, etc.) perimeter corners 360 or have a different configuration to transfer and spread load from the carrier 320 to different points or areas on the upper surface 27 of the mat 26 and/or any other desired purpose(s).

[00088] If desired, the base 350 may include at least one gripper 366 configured to grip or engage the mat 26 or other component to prevent, limit or reduce rotation of the base 350 and carrier 320 relative to the mat 26, or one or more other desired purposes. The gripper 366 may have any suitable form, construction, components, configuration and operation. In this embodiment, the gripper 366 includes multiple spaced-apart teeth 370 protruding downwardly from the base 350 and configured to engage the mat 26. While four such teeth 370 are shown, any desired number of teeth may be included, such as two, three, four, five, six, seven, etc. For example, the teeth 370 may be positioned proximate to the bore 354 of the base 350 (e.g. Figure 8C) so that they fit within the recess 33 (e.g. Figure 5D) extending around the hole 32 of the mat 26. The four exemplary spaced-apart teeth 370 will seat within the oval-shaped recess 33 at different positions so that they will abut the wall of the recess 33 upon any attempted twisting or rotational motion applied to the base 350 or carrier 320, preventing, limiting or reducing actual rotation thereof. In other embodiments, any desired number of grippers 366 (e.g. one, two, three, four, five, six, etc.) may instead or also engage the upper surface 27 of the mat 26 or raised traction promoting elements (treads) 31 (e.g. Figure 4C) formed in or extending from the upper surface 27 of the mat 26 or any other component(s).

[00089] Referring back to Figure 5A-C, the exemplary system 300 may also include at least one releasable lock 380 configured to assist in securing the position of the base 350 and carrier 320 relative to the mat 26. The lock 380 may have any suitable form, configuration, components, construction and operation. For example, the illustrated lock 380 is generally tubular in shape and includes a threaded bore 382 (e.g. Figures 9A-E) configured to mate with the threaded upper end 322 (e.g. Figure 5E) of the carrier 320. In this embodiment, after the illustrated base 350 is positioned over the lower end 324 of the carrier 320, the lock 380 is screwed down onto the carrier 320 until its lower surface 384 abuts the base 350, effectively sandwiching the base 350 against the mat 26. For example, the lock 380 may force and hold the base 350 in abutting contact with the mat 26 and assist in holding the carrier 320 in its locked position on the mat 26. In this example, as shown in Figures 9A-E, the body 386 of the lock 380 includes numerous at least partially hollowed spokes 388, such as for ease of gripping and rotating the lock 380, to optimize the size, weight and/or material used in manufacturing the lock 380 or other desired purposes(s). However, the spokes 388 may not be included in various embodiments.

[00090] Referring again to Figures 5A-C, the upright member support system 300 may also include one or more releasable upright member anchors 390 useful to help secure the position of the upright member 310 relative to the carrier 320 or other desired purpose. The upright member anchor 390 may have any suitable form, configuration, components, construction and operation. For example, the anchor 390 may include one or more ratchetlike mechanisms, wingnuts or other component(s) arranged and adapted to releasably engage the upright member 310. In some embodiments, the anchor 390 and lock 380 may be integrally formed as a single component or as interconnected components.

[00091] In this embodiment, as shown in Figure 5E, the anchor 390 includes at least one compression member 394 and at least one compression nut 400. The compression member 394 may have any suitable form, configuration, construction and operation. The illustrated compression member 394 is a spring ring 395 configured to at least partially engage, squeeze or grip the upright member 310. The exemplary compression nut 400 is configured to bias and hold the compression member 394 in gripping engagement with the upright member 310 (e.g. above the lock 380). Any suitable arrangement may be used. In the present embodiment, as shown in Figures lOA-C, the body 396 of the illustrated compression member 394 is formed in an overall ring-like shape and is at least partially deformable. If desired, the compression member 394 may have one or more grip-enhancement features that encourages or enhances its ability to grip the upright member 310. For example, in the illustrated embodiment, the body 396 of the compression member 394 has a sine-wave shape. Other examples may include a series of ribs, pimples, cut-outs or rough areas formed in the outer surface of the body 396 of the compression member 394. In this embodiment, the compression member 394 is the only component of the upright member support system 300 that clamps or grips the upright member 310. However, in other embodiments, multiple components of the support system 300 may grip or clamp the upright member 310.

[00092] Referring now to Figures 11A-D, the compression nut 400 may likewise have any suitable form, configuration, construction and operation. It should be noted that while the term nut is used as part of the term "compression nut", this component 400 need not necessarily be a nut as that term is typically defined or known in a technical sense. Thus, the compression nut 400 is not limited to a "small flat piece of metal or other material, typically square or hexagonal, with a threaded hole through it for screwing onto a bolt as a fastener" or the like, but may take any other form suitable for the purposes described herein or as will otherwise be apparent from this specification and the appended drawings and claims.

[00093] For example, the illustrated compression nut 400 is generally tubular and includes a threaded bore 404 configured to mate with the threaded upper end 322 of the carrier 320 around the compression member 394. In this embodiment, as shown in Figure 5E, the compression nut 400 screws onto the carrier 320 above the lock 380, and inwardly biases, or places crushing forces, upon the compression member 394. For example, the illustrated compression nut 400 may bias the compression member 394 between (i) one or more interior ledges 408 of the compression nut 400, (ii) one or more upper lips 332 of the carrier 320 and (iii) the upright member 310. In this example, the ledge 408 and lip 332 may be angled to assist in biasing and/or retaining the compression member 394 into engagement with the upright member 310. In some applications, the compression nut 400 may be threaded or moved down the carrier 320 sufficiently far to abut the lock 380.

[00094] If desired, the various components of the upright member support system 300 may be reusable and constructed of any suitable material that is sufficiently strong to bear and transfer loads placed upon the upright member 310, and sufficiently weather-resistant, wear- resistant and durable, as desired. In this embodiment, the carrier 320, base 350, lock 380 and compression nut 400 may, for example, be constructed of fiber-reinforced plastic, such as glass-filled polyurethane or glass-filled nylon. The exemplary compression member 394 may, for example, be constructed of unfilled nylon.

[00095] Now referring to Figures 5B, 5C & 5F, in yet another independent aspect of the present disclosure, the system 300 may include one or more directional indicators 414 configured to provide a visual indication that the lower end 324 of the carrier 320 is in locking relationship with the support surface 16. The directional indicator 414 may have any desirable form, configuration and operation. In this embodiment, the directional indicator 414 is provided on the base 350 to indicate when the coupler 336 (e.g. Figure 5B) is in locking engagement with the mat 26. For example, the directional indicator 414 may be in the form of one or more visible arrows 416 that indicates when the toes 344 of the exemplary coupler 336 are in a locked position relative to the hole 32. In this embodiment, the carrier 320 is locked to the mat 26 when one arrow 416 points to the edge 44a of the upper lip 46 of the mat 26. In other embodiments, the arrow 416 may point to the edge 44b of a lower lip 54, or another desired part of the mat 26 or support surface 16 to indicate the carrier 320 is locked to the mat 26.

[00096] Referring to Figures 5A-F, in an exemplary embodiment of a method of use of the illustrated upright member support system 300, the carrier 320 may first be releasably secured to one or more mats 26 of the support surface 16. For example, the carrier 320 may be releasably secured to one or more holes 32 (e.g. locking pin hole) of one or more mats 26, such as described above. The exemplary releasable base 350 is placed over and down the carrier 320 so it covers at least part of the lower end 324 thereof and rests upon, contacts or abuts the mat 26, such as also described above. The illustrated lock 380 is engaged with (e.g. screwed onto) the carrier 320 above the base 350. If desired, the lock 380 may be tightened relative to the carrier 320 and base 350 sufficient to push or secure the base 350 into the desired contact or engagement with the mat 26. In some embodiments, the lock 380 may assist in securing the teeth 370 of the base 350 into the recess 33 of the hole 32 or otherwise grip the mat 26 or other component(s).

[00097] The exemplary upright member 310 is inserted into the bore 326 (e.g. Figure 7A) of the exemplary carrier 320 (this can be done at any time, typically after the carrier 320 is secured to the support surface 16). In this particular embodiment, for example, the upright member 310 rests upon an internal surface 330 of the carrier 320. Before or after the upright member 310 is inserted into the illustrated carrier 320, the anchor 390 is releasably secured to the carrier 320 (e.g. above the lock 380). For example, the illustrated compression member 394 may be placed inside the compression nut 400, which is then threaded onto the carrier 320 above the lock 380. Once the upright member 310 is inserted into the exemplary carrier 320, the illustrated anchor 390 is adjusted to grip the upright member 310. For example, the compression nut 400 may be tightened onto the carrier 320 until the compression member 394 grips the upright member 310 as desired. The exemplary system 300 is reusable and may be disassembled for maintenance, reuse or repair, such as, for example, by reversing the order of some or all of the above actions.

[00098] In some embodiments, the geometry, interaction and/or engagement of the various parts of the exemplary upright member support system 300 and with respect to the upright member 310 and support surface 16 are configured to maintain the upright member 310 in the desired upright position (e.g. vertical) relative to the support surface 16 under expected operating conditions. In some cases, these conditions may include up, to or at least, approximately 200 lbs. of wind forces or other loads imparted to the upright member 310 and/or to meet current and expected OSHA load targets for leaning loads on safety barriers. For example, referring to Figures 5B & 5E, in the present embodiment, the upright member 310 is supported by the carrier 320 and gripped by the compression member 394 so that when the upright member 310 bends under normal or expected use conditions, it acts upon the interior wall 346 of the exemplary carrier 320. Much or all of the expected forces placed upon the illustrated carrier 320 by the bending upright member 310 are transferred to the base 350, which is configured to displace at least some, most or all of those forces to the support surface 16.

[00099] Preferred embodiments of the present disclosure thus offer advantages over the prior art and are well adapted to carry out one or more of the objects of this disclosure. However, the present invention does not require each of the components and acts described above and is in no way limited to the above-described embodiments or methods of operation.
