Description

    FIELD OF THE INVENTION
  • The invention relates generally to the field of safety equipment and more particularly to a safety mat for use with a parapet wall having a cap.
  • BACKGROUND OF THE INVENTION
  • Many flat building roofs have parapet walls around the edges of the roof. The parapet wall in turn usually has a cap over the top of the wall and extending partially down each side of the wall for sealing the top of the wall. This cap is made of a variety of materials including sheet metal. In many cases in order to access the roof a ladder must be raised to the side of the parapet wall and the person trying to access the roof will have to step onto and over the wall from the ladder. Such a maneuver can be dangerous under the best conditions and especially so if the cap is wet from dew, rain snow, sleet or ice.
  • The concept of utilizing a mat over a surface to increase traction is well known. Various designs of mats for use in roofing settings have been put forth. U.S. Pat. No. 5,935,676 to Meniman et al. discloses a slip resistant floor mat for use on angled roofs. The mat includes a layered anti-slip surface with cloth reinforcing strip. The mat is held in place by hooks attached to the mat at one end.
  • Another example is seen in U.S. Pat. No. 4,674,245 to Turner in which a portable roof mat is disclosed. This mat is designed to be utilized on roof surfaces to create a walkway on a roof.
  • Other safety mat designs have incorporated features pertaining to how the anti-slip surface is to be designed. For example, U.S. Pat. No. 4,137,356 to Shoemaker et al. discloses a specific pattern of raised projections for supplying traction.

  • DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
  • Referring now to FIG. 1 a safety mat 10 according to a preferred embodiment is shown. In this embodiment the mat 10 is preferably made of rubber and is generally rectangular in shape, although other shapes could be utilized. The mat 10 includes opposite length sides 12, 14 and a opposite width sides 16, 18. The mat 10 is comprised of three primary regions extending between the width sides 16, 18. The center region 20 is of a crossing pattern defining opening 22 for allowing moisture to pass through. On each side of the center region is a solid side region 24. Furthermore, the mat 10 includes a top side 26 that is coated with an anti-slip coating like a sandpaper for grip. The bottom side (not shown) is not coated to protect the surface under the mat 10.
  • The safety mat 10 further includes a cap strap system. This cap strap system includes two opposite pairs of cinch down straps 28, 30. The first pair of straps 28 extends from the interior of the mat near opposite width sides 16, 18 and over the first length side 12. The location near, but not at the width sides 16, 18 ensures that the straps 28 stays over the mat 10 during use. The opposite pair of straps 30 extends from the interior of the mat near opposite width sides 16, 18 and over the second length side 14. Each strap includes an end 32 hanging over the length sides 12, 14 and each end 32 is attached to a hook 34. In this preferred embodiment the cinch down straps 28, 30 are of a releasable cam-buckle design; however any tightening straps known in the art could be utilized. For example, bungee cords or racheting straps could be used. This holds tile for any of the cinch down straps described herein.
  • The safety mat 10 also includes a ladder strap system. This ladder strap system includes a pair of ladder cinch down straps 36. The ladder cinch down straps 36 extend from the interior of the mat 10 closer to the first length side 12 than the second length side 14 and preferably a ladders-width apart and centered on the middle of the width of the mat 10. The ladder cinch down straps 36 do not extend past the length sides 12, 14. Each of the ladder cinch down straps 36 includes an end 38 including a hook 40.
  • Finally, the safety mat 10 includes a ladder mounting system. This ladder mounting system includes a pair of ladder lifting straps 42. The ladder lifting straps 42 extend from the interior of the mat 10 closer to the second length side 14 than the first length side 12 and preferably a ladders-width apart and centered on the middle of the width of the mat 10. The top 44 of one of the ladder lifting straps 42 and the bottom (not shown) of the other ladder lifting straps preferably includes hook and loop fasteners.
  • Referring now to FIGS. 2-4 the safety mat 10 is shown in use. In most cases in order to use the safety mat 10 the mat must be raised into position and attached to a cap on top of a parapet wall 60. This is best accomplished by attaching the mat 10 to a ladder 50. The ladder 50 includes side rails 52 and a plurality of steps 54. The ladder cinch down straps 36 are attached to the side rails 52 several steps down from the top of the ladder 50 as seen in FIG. 2. Referring now to FIG. 3, the ladder lifting straps 42 are wrapped around a ladder step 54 above where the cinch down straps 36 are placed and secured to each other utilizing the hook and loop fasteners, thus securing the mat 10 to the ladder 50.
  • Next, the ladder 50 is positioned with the safety mat 10 in contact with the cap 62 of a parapet wall 60. Preferably the safety mat 10 is positioned with the center region 20 extending slightly over the sides 64 of the cap 62. This will keep moisture from building up on top of the safety mat 10. Once the ladder 50 is raised and positioned, the person utilizing the mat 10 can climb the ladder and undo the ladder lifting straps 42 to allow the safety mat 10 to overlap the top of the cap 62 as seen in FIG. 4.
  • The final step of the installation is to secure the cap strap system to the cap 62. The cinch down straps 28, 30 are put into place with the hook 34 over a lower edge 66 of the cap 62. The cinch down straps 28, 30 are then tightened and the safety mat 20 is secured to the cap 62. It is important to note that preferably the ladder cinch down straps 36 remain in place in order to keep the ladder in place during use.
  • While the principles of the invention have been shown and described in connection with specific embodiments, it is to be understood that such embodiments are by way of example and are not limiting.
