Abstract:
A work mat on which a worker stands while operating a machine for comfort and for the purpose of easing of physical stress caused by standing on a non-compressible floor during a work day. The work mat includes a wooden platform with a peripheral synthetic border which tapers from the floor up to the top edge of the wooden platform. In addition, the synthetic border extends inward about one half inch under the peripheral edge of the wooden platform, thereby elevating the wooden platform above the floor. The wooden platform is therefore suspended over the floor and can flex up and down as a user walks on or stands on the mat, thereby absorbing some of the shock of walking and moving on the floor. The compressibility of the wooden platform adds to the comfort of the work mat as well.

       [0001]    This application claims priority to U.S. Provisional Application Ser. No. 61/967,755 filed on Mar. 24, 2014 and is incorporated herein by reference in its entirety. 
     
    
     TECHNICAL FIELD 
       [0002]    The present invention relates to the field of ergonomic and safety anti-fatigue matting. 
       BACKGROUND OF THE INVENTION 
       [0003]    Work-related musculoskeletal disorders (MSD) result when there is a mismatch between the physical capacity of workers and the demands of the job. Musculoskeletal disorders are the leading cause of disability of people in their working years, afflicting over 19 million workers. One-half of the nation&#39;s work force is affected at some time during their working lives. Statistics show a steady increase in musculoskeletal disorders. Each year thousands of workers in the United States report work related MSDs such as tendonitis, epicondylitis, carpal tunnel syndrome, and back injuries. Many of these are caused or aggravated by work related stressors such as lifting, reaching, pulling, pushing, and bending. 
         [0004]    About one-third of all occupational injuries and illnesses stem from over exertion and/or repetitive motion. Cost to the nation in direct work&#39;s comp costs exceed $20 billion. Several high profile studies have been conducted over the last few years by respected scientists from the National Academy of Sciences (NAS), the National Institute for Occupational Safety and Health (NIOSH), and others. 
         [0005]    Ergonomics is the applied science of equipment design for the workplace, intended to maximize productivity by reducing operator fatigue and discomfort. 
         [0006]    According to occupational therapy doctors a person standing, walking and working on hard surfaces such as concrete for prolonged periods of time may develop significant cumulative trauma or other injury, such as musculo-skeletal illness, pain, fatigue and inhibited circulation. Both load bearing stress and the gait cycle i.e. walking on concrete requires compressive force and stress loads on a body&#39;s muscles, joints and tendons which overtime wear out causing pain, discomfort and often times requiring painful surgery. In these conditions the musculo-skeletal structure is basically the body&#39;s internal shock absorption system. Unfortunately, heel spurs and plantar fasciitis are common problems as they are a direct interface to the concrete and the first point of shock absorption. Other systemic injuries include the knees, pelvic, lower back and vascular related problems. The pain, fatigue and general discomfort can result in tendinitis, arthritis as well as reduced worker productivity, higher turnover and diminished quality and moral. 
         [0007]    In an attempt to alleviate such occupational hazards, employers often place cushioned matting on floors proximate employee workstations. Unfortunately, as employees walk, twist and turn on these mats they sprain, strain and tear soft tissue and other related musculo-skeletal matter in their body&#39;s due to their foot sticking while being compressed into the mat. These types of injuries are analogous to downhill skiing injuries in that they more frequently occur when more fatigue is present in the workers typically later in their shift. Due to the frequency and costs of these types of injuries, major companies are restricting the use of matting to limited static jobs only where no walking, twisting and turning is required. Also, bunching and curling of matting create tripping hazards in many settings, including occupational environments. Such hazards are a top recordable complaint in occupational settings. In some cases, the matting is taped, glued and screwed to the floor making that matting a permanent one time use product. Other mats are fastened to the floor via bolts or screws. However the bolts and screws can be the cause of tripping hazards for personnel. 
         [0008]    Wood floors are commonly used on basketball and volleyball courts as well as for other sports as a preferred alternative to concrete because of wood&#39;s softer, more therapeutic and forgiving composition. Therefore wood floors help reduce injuries in these high impact activities and are now the standard best practice for collegiate and professional sports. Some wood floors are also constructed to maximize a spring type effect utilizing some methods of suspension to further compression absorption and reduce stress. Many factories were made with wood floor during the industrial revolution for these same reasons when they were built on multiple levels. The modern industrial complex of today is generally one level with a floor consisting of concrete. While efficient and cost effective from a construction standpoint, concrete is not very ergonomic in nature as a work floor surface. Due to the non-compressible nature of concrete, a workers joints, tendons and muscles absorb all of the impact due to walking, jumping or any other movements on the floor. Cumulative job activities performed on concrete can and potentially will lead to a multitude of back and lower extremity injuries. 
         [0009]    The present invention incorporates a modular ergonomic wood work platform raised slightly above a support surface such as a floor providing cushioning and resilience for users thereof. The purpose of this invention is to offer occupational workers a therapeutic, flexing and cushioning work surface to protect them from the aforementioned health risks of working, walking and standing on a concrete floor. or an anti-fatigue mat usable in a modular form to build platforms. This ergonomic wood work platform is raised off the floor to offer suspension thus promoting a spring effect for absorbing and returning compression force resulting in reduced stress loads and compression force providing an anti-fatigue mat usable in modular form to build platforms for people as an alternative to walking or standing on concrete floors. This product is constructed with a modular design having tapered peripheral borders connecting together and to the raised wood platform providing a seamless transition for a snug gap-free fit. The vertical plane or edge of the wood has a thickness providing connection points that provide a leveling effect and further enhance the fit of said modules.

       SUMMARY OF THE INVENTION 
       [0011]    In accordance with the present invention, there is provided a modular wooden ergonomic safety work mat comprising, consisting of, or consisting essentially of at least one and preferably two mating work mate sections. A female work mat section, a male work mat section and any desired number of expander work mat sections can be assembled together providing a work platform. 
         [0012]    For example, the female work mat section contains a first rectangular wooden platform bounded by a first border on three sides. The first rectangular wooden platform has a top surface, a bottom surface, two long sides and two short sides. The first border surrounds the first rectangular wooden section on a first one of the long sides and on the two short sides. The first border has a generally right triangular cross-section wherein a long side of the right triangle rests on the floor. The hypotenuse of the right triangle extends from about the top edge of the first rectangular wooden platform down to the floor, and a short side of the right triangle extends from a top edge of the first rectangular wooden platform down to the floor with an outer surface of the short side of the right triangle adjacent to an outer surface of a first one of the long sides and the two short sides of the first rectangular wooden platform. The first border includes two spaced apart web elements which are parallel to the short side of the right triangle. The first of the web elements is spaced apart from the short side of the right triangle and thereby forms a first aperture sized to accept a first square wooden dowel of a first size. The second of the web elements is spaced apart from the first web element and thereby forms a second aperture to accept a second wooden dowel of a second size. The first border has a first horizontal web member extending from the intersection of the short side and the long side inward under an outer edge of the first one of the long sides and on the two short sides of the wooden platform thereby elevating the first rectangular wooden platform above a top surface of the floor. The second of the two long sides of the first rectangular wooden platform has a plurality of spaced apart horizontal biscuit slots formed therein. 
         [0013]    The male work mat section contains a second rectangular wooden platform bounded by a second border on three sides. The second wooden platform has a top surface, a bottom surface, two long sides and two short sides. The second border surrounds the second rectangular wooden section on a first one of the long sides and on the two short sides. The second border has a generally right triangular cross-section wherein a long side of the right triangle rests on the floor. The hypotenuse of the right triangle extends from about a top edge of the second rectangular wooden platform down to the floor, and the short side of the right triangle extends from a top edge of the second rectangular wooden platform down to the floor with an outer surface of the short side of the right triangle adjacent to an outer surface of a first one of the long sides and the two short sides of the second rectangular wooden platform. The second border includes two spaced apart web elements. The web elements are parallel to the short side of the right triangle. The first of the web elements is spaced apart from the short side of the right triangle and thereby forms a first aperture sized to accept a first square wooden dowel of a first size. A first square wooden dowel extends outward from the first aperture. The second of the web elements is spaced apart from the first web element and thereby forms a second aperture to accept a second wooden dowel of a second size. A second square wooden dowel extends outward from the second aperture. The second border has a second horizontal web member extending from an intersection of the short side and the long side inward under an outer edge of the first one of the long sides and on the two short sides of the wooden platform thereby elevating the second rectangular wooden platform above a top surface of the floor. The second of the two long sides of the second rectangular wooden platform has a plurality of spaced apart horizontal biscuits extending therefrom. The biscuits are spaced apart to match the spacing of the biscuit slots of the first rectangular wooden platform. 
         [0014]    An expander work mat section contains a third rectangular wooden platform bounded by a third border on a first short side and a fourth border on a second short side. The third wooden platform has a top surface, a bottom surface, two long sides and two short sides. The third and the fourth borders have a generally right triangular cross-section wherein a long side of the right triangle rests on a floor, a hypotenuse of the right triangle extends from about a top edge of the third rectangular wooden platform down to the floor, and a short side of the right triangle extends from a top edge of the third rectangular wooden platform down to the floor with an outer surface of the short side of the right triangle adjacent to an outer surface of the two short sides of the third rectangular wooden platform. The third and the fourth borders include two spaced apart web elements. The web elements are parallel to the short side of the right triangle. The first of the web elements is spaced apart from the short side of the right triangle and thereby forms a first aperture sized to accept a first square wooden dowel of a first size. The second of the web elements is spaced apart from the first web element and thereby forms a second aperture to accept a second wooden dowel of a second size. The third and fourth borders have third and fourth respective horizontal web members extending from an intersection of the short side and the long side inward under an outer edge of the two short sides of the third wooden platform thereby elevating the first rectangular wooden platform above a top surface of the floor. The first of the two long sides of the third wooden platform has a plurality of spaced apart biscuit slots formed therein and spaced apart to match the spacing of the biscuits in the male work mat section. The second of the two long sides of the third rectangular wooden platform has spaced apart biscuits extending outward therefrom. The biscuits are spaced apart to match the spacing of the biscuit slots in the female work mat section. The third and fourth borders have square dowels extending therefrom on border ends adjacent to the second of the two long sides of the third rectangular wooden platform. The long sides of the first, second and third wooden platforms are equal in length and thickness.

         [0073]    As illustrated best in  FIGS. 1 ,  3 ,  4 , and  5 , the sockets  17  of the first inner edge  2  of the first section  10  cooperatively engage the opposing projections  16  of the third inner end edge  5  of the third center section  12 . The sockets  17  of the third inner end edge  4  of the third center section  12  cooperatively engage the projections  16  of the second inner end edge  3  of the second section  11  to form the work mat  1 . 
         [0074]      FIG. 2  shows an extendable middle or center section  11  including alternating sockets  17  and projections  16  on each one of the opposing end edges  7  and  8 . 
         [0000]    including one female end section  10 , one male end section  12  and a selected number of expander sections  11 . If only a short length of work mat is required for a particular installation, then only a female section  10  and a male section  12  will be assembled to one another. When a longer work mat is needed, any number of expander sections  11  are added between the female section  10  and the male section  12  to provide the desired length of work mat  5 .  FIG. 1  shows a work mat  5  including a female section  10  and a male section  12  with one expander section  11 . 
         [0075]      FIG. 2  shows a female section  10  including a rectangular wooden platform  14  including a top surface, a bottom surface, two long sides and two short sides. A border  13  extends around two short sides and one long side of the rectangle. The exposed side of the wooden platform  10  contains biscuit slots  17  to provide a proper joint with a mating section. The wooden platform  14  is one fourth to one inch or more thick. Preferably, the wooden platform  14  is in the range of one-half to three quarters of an inch. 
         [0076]    As shown in the figures, the border  13  covers the edges of wooden platform  14  and tapers down to the floor to prevent a user from tripping on one of the edges. As seen in  FIGS. 4-9 , the border is a longitudinal extruded member having a generally triangular cross-sectional shape. With reference to  FIG. 8 , the triangle is a right triangle wherein the sloped surface or hypotenuse  26  is the only exposed side and provides an inclined plane reaching from the floor to the top surface of the wooden platform  14 . The border  13  is formed form an extruded longitudinal tube or strip of polymeric material having a triangular cross sectional. A flat bottom or base  21  rests upon a support surface such as a floor. An end section or end wall  24  of the border  13  integrally joins the base  21  at a right angle of 90 degrees forming the short leg of the triangular member extending upward for abutting and cooperative engagement with a selected edge of the section or panel and is generally up to about two inches high and in at least one embodiment ranges from one fourth to two inches high. 
         [0077]    The top load supporting surface  22  of the border  13  integrally joins the top edge of the end wall  24  to the opposing front end edge of the base  21  at an acute angle of 45 degrees or less, preferably an angle less than thirty-five degrees and more preferably from about 5 to 35 degrees. One embodiment of the invention includes a border having a base  21  and top surface  26  forming an acute angle A in the range of eight to thirty-five degrees wherein the length of the top surface or hypotenuse  26  is in the range of two to eight inches in length and more preferably in the range of three to four inches in length. As shown in the drawings, the top surface  26  of the border forms an inclined plane extending upward from a tip  40  formed by a junction with the base  21  the floor or support surface, toward the top of the short end wall  24  to integrally join the front edge of the base  21  forming the hypotenuse whereby the border cross-sectional shape defines an inclined plane or slope. As shown in  FIGS. 6-10  the plane is a straight line forming a substantially flat inclined plane; however, it is anticipated that the top surface  26  forming the hypotenuse could extend upward a selected length forming an extended included plane portion having a greater slope which then extends horizontally outward or at a selected obtuse angle  37  or curve forming a leg  39  joining the end wall  24  and abut the edge of the selected section as shown in  FIG. 13 . It is contemplated that the top surface  26  can also be extruded or molded having a slightly curved shaped forming either surface concave or convex surface extending from the tip  40  or pointed portion resting on the support surface to the end wall or having a curved portion therein between so long as the tip rests upon the support surface and the opposing end joins the end wall  24  providing a generally seamless transition from the border to the surface of the platform section  14 . Moreover, the top sloped surface  26  may include an irregular, stamped, grooved or stamped pattern  42  to improve traction and minimize slippage by the user. 
         [0078]    The web  36  comprising at least two spaced apart vertical walls  22  and  23  are parallel to the short end  24  and provide compression and lateral support to the triangular boarder  13  against collapse of the hypotenuse  26 , when the boarder  13  has a downward load applied.  FIGS. 6-11  show an end view of a border extruded from a polymeric material showing the hollow longitudinal cavities between the tip and end wall separated by vertical wall sections of webbing disposed between the top surface and base. Dowel members are inserted into the distal ends of the longitudinal cavities as means of joining two adjacent sections of border together. Of course, additional longitudinal members can be inserted into the longitudinal passages of the border to provide structural strength thereto and minimize compression of same under load. 
         [0079]    A border base flange which may be an extension of the base  21  defines a flange  30  extending past the end  24  of the border. The extension  30  has a length in the range of one quarter inch to two inches and is preferably in the range of three quarters inch to one inch long. The thickness of the extension  30  is in the range of one eight to one quarter inches thick. 
         [0080]      FIG. 8  shows the wooden platform  14  resting on the extension  30  of the border piece  13 . This provides a gap  20  between the bottom surface of the platform  14  and the top surface of the floor. This gap  20  is preferably in the range of one eighth of an inch to two inches. A spacer  25  as shown in  FIG. 11  may be added to the between the platform  14  and the top surface of the flange  30  to increase the thickness of the base flange to provide a seamless smooth surface between the surface  26  of the border and the platform surface  14 . 
         [0081]    With reference to  FIGS. 8 and 9 , it can be seen that the top surface of the platform  14  is at the same height as the top edge of the border  13 . The height  24  of the triangular boarder  24 , the thickness of the wooden platform  14 , and the thickness of the extension  30  and spacer  25  (if used) are selected so that the top surface of the platform  14  is about even with the top edge of the border  13 . 
         [0082]      FIGS. 4-5 , and  6 - 7  show mating pairs of female-male ends of the border piece  13 . The male end in  FIG. 7  is defined by the two wooden dowels  18  which will be forcibly inserted into the respective apertures  19  of the female end in  FIG. 6 . Therefore, the combination of dowels  18  inserted into apertures  19  and the insertion of the biscuits  16  into the biscuit holes  17  provide a secure joint between mating sections of work mat. The biscuits  16  insure that when a user stands on one section of the work mat, edges of that section don&#39;t dip below the adjoining and causing a trip hazard. If desired, the mating edges of the wooden platforms and the biscuit joints are glued to provide a stronger joining of the sections. 
         [0083]      FIGS. 10 and 11  show partial mating sides of wooden platforms  14  of two modular sections of the work mat  5 . The wooden edges of adjoining section alternately contain biscuit slots  17  and biscuits  16  which inserted into biscuit slots  17  to align and secure the edges of the adjacent wooden platforms  14 . If desired, glue is included in the joining of two wooden platforms  14 . With this biscuit joint, the top surfaces of the two adjacent wooden platforms are guaranteed to be approximately flush with one another, thus preventing trip hazards at the edges. 
         [0084]      FIG. 15  is an end view of a border extruded from a polymeric material showing the hollow longitudinal cavities between the tip and end wall separated by vertical wall sections of webbing disposed between the top surface and base, and showing a portion of the base extending pass the end wall a selected distance for supporting the edge of a panel above the support surface or floor whereby the working mat is supported a selected distance above the support surface and a compression pad  35  abuts the base flange and is disposed between the platform and the supporting surface. 
         [0085]    It is anticipated that at least the top surface of the wooden platform  14  of the modular sections are coated with a smooth, textured, granular or electro-static dissipative finish or laminate. 
         [0086]    Furthermore, a compressible material can be fastened underneath or above the wood offering further ergonomic properties combined with the function of said platform. An even or flush horizontal work surface can be provided where the highest point of the vertical wall edge of the tapered border adjoins the top work surface of a compressible material. A seamless and flush joint is formed with the top of a floor panel or floor section supported by a compressible bottom layer. The layer of compressible material applied to the top of said platform has a compression force deflection according to ASTM D 3574-08 up to 75 psi and preferably from 5 to 75 pounds per square inch. A compressible material may be used used on the bottom side of the floor platform or section supporting same either alone or in combination with compressible material on the top surface which provides the floor panel, floor platform or section with a compression force deflection according to ASTM D 3574-08 up to 75 psi and preferably from 5 to 75 psi. The compressible material on a top surface of the platform, section, or floor panel ranges in compression set under constant deflection according to ASTM D 1056-00 up to 70 psi. and preferably from 3 -70 psi. The compressible material on the bottom side ranges in compression set under constant deflection according to ASTM 1056-00 up to 70 psi and preferably from 3-70 psi. 
         [0087]    The attached compressible material comprises of an open or closed cell foam material, or vinyl like composite. Both open-cell and closed-cell products are available in a large variety of compression deflection ranges. Padding may still be capable of providing proper ergonomic support to both stationary and walking activities 
         [0088]    Open cell material looks and acts like a sponge. Closed cell material looks like a bunch of bubbles glued together. When force is applied to an open cell product, after release of the force, the product bounces back to shape because the open cell structure allows air to flow back into the material. On the contrary, when force is applied to a closed cell product, some of the bubbles may burst, resulting in a loss of cushion and support. The closed cell structure impedes the flow of air so that the structure does not return to its original shape as quickly after release of the force. 
         [0089]    Open-cell foam products typically have lower compression set numbers. However, their structure permits the absorption of water, which may require them being sealed to prevent mold and mildew when utilized in the present invention. For example, Rubberlite Inc. offers a polyurethane open-cell product called HYPUR-CEL® H0705 that may be used in the present invention. Rubberlite Inc. also offers closed-cell sponge rubber materials that may be used in the present invention. Both products exhibit 40% compression set. Armacell LLC offers a neoprene blend named IG-2 that supports 25% compression set. These materials are provided for exemplary purposes only and not intended to limit the scope of the present invention. 
       EXAMPLE 1 
       [0090]    For example, one preferred embodiment of the present invention would include the following features and is described as follows: 
         [0091]    The modular wood platform ranges from ¼″ to 1″ in thickness with the bottom surface raised off the floor with a range of ⅛″-2″ for suspension effect comprising a spring bounce and absorption effect for weight bearing stress in static and rhythmic posture. 
         [0092]    A tapered border provides safe ingress and egress transition on and off from said wood platform is affixed or attached to a wood platform providing a seamless transition therewith. The attached border comprises a polymer and more particularly a plastic or other synthetic material such as polyvinylchloride (“PVC”), an elastomer material, a rubber material, a polyblend (plastic and rubber composite material), or other polymeric compound or like material providing good resilience, traction, controlled compressibility, and insulating properties with a slope ranging up to 45 percent, more preferably from 1 to 45 percent, more preferably from 5 to 40 percent and even more preferably from 8 to 35 percent. In one preferred embodiment, the attached border ranges in width from 2 to 8 inches depending upon the thickness of the wood platform base with a slope ranging from 8%-35%. 
         [0093]    In at least one embodiment, the sloped attached border system includes panels or sections having two or three side and end surface areas opposite the sloped side area comprising at least one vertical plane or side edge and one horizontal plane ranging from ½″ to 1 inch for adjoining the panels or sections of the wood platform. 
         [0094]    The sloped attached border system comprises a tapered body having a slope in a range of from 8-35% with two or three side and/or end surface edge areas opposite the sloped side with a vertical plane or thickness ranging from ⅛ to 2 inches. The adjoining sloped border contains a channeled or hollow inner configuration that enables modular connection methods of said ergonomic wood and border system via a biscuit and insert configuration. 
         [0095]    The sloped border having an internal construction contains at least one, preferably two, and more preferably a plurality of between 3-5 channels for connection to the other like modular constructed platform utilizing connectors made of wood, plastic, nylon, PVC or metal in either modular or permanent male and female connection in tongue and groove form and function. The wood platform ranges in height up to three inches, and typically has a thickness of from ⅛ to 2 inches with an attached border system containing a sloping or tapered edge or chamfered border of 5-35 percent and having an overall width extending from the wood platform outer peripheral edge of from 2 to 8 inches. 
         [0096]    The chamfered border optionally includes a hollowed interior portion optionally including a selected number of spaced apart vertical support walls or up to five inside vertical supports and at least one and more preferably from 3 to 5 horizontal support members to provide modular male/female connection. A second wood platform or section with an adjoining sloped or chamfered border with a selected corresponding sized top vertical range of for example ½ to 2 inches and a bottom sloped vertical height of under ⅜″ can be connected thereto. 
         [0097]    The surface of the wood platform with adjoining sloped border system can be coated with a smooth, textured, granular, or electro static dissipative finish or laminate and may include compression properties. A modular raised wood platform with a sloped border on up to four sides with the vertical riser consisting of PVC or like material on the bottom surface is either integrated into the sloped border material or independently fastened to the bottom of wood platform. The raised wood platform comprising or consisting of a sloped border system supports the wood above a resting surface or the ground while additionally providing anti-slip bottom surface traction to said platform. The horizontal plane of surface area of the raised wood platform is even with or as much as ⅛″ greater than the top vertical rise of the tapered border.
