- In the following, various embodiments of a shock absorbing mat or tile (hereinafter referred to as “mat” for convenience only) are described. Broadly, each shock absorbing mat comprises a body having a generally planar, major top surface and an opposite major bottom surface, and a plurality of shock absorbing members depending from the bottom surface. At least one of the shock absorbing members has at least one relief formation formed therein. The at least one relief formation is designed, shaped or otherwise configured to accommodate lateral expansion of the shock absorbing member during axial compression thereof. The shock absorbing mat is designed to inhibit or prevent the transmission of vibration and/or noise. The shock absorbing mat can be used in isolation or with other shock absorbing mats to form a floor covering. The size and shape of the shock absorbing mat can be adjusted to suit particular environments in which the shock absorbing mat is used and to suit the desired floor surface area to be covered. Particular non-limiting examples of shock absorbing mats and floor coverings employing the same will now be described.
- Turning to
FIGS. 1 to 6 , an embodiment of a shock absorbing mat is shown and is generally identified byreference character 100. Theshock absorbing mat 100 is of unitary construction and is formed of rubber material or other suitable material such as for example natural rubber, styrene-butadiene rubber (SBR), recycled rubber etc. Theshock absorbing mat 100 is generally square-shaped and comprises abody 102 having a generally planar, majortop surface 110, an opposite majorbottom surface 112 and four (4) peripheral side surfaces 114 extending between thetop surface 110 and thebottom surface 112. Thebottom surface 112 comprises a substantially planarcentral portion 116 surrounded by a downwardly extendingperipheral lip 118. - A plurality of spaced-apart
shock absorbing members 104 arranged in an array depend from thecentral portion 116 of thebottom surface 112. Theshock absorbing members 104 of adjacent rows (or columns depending on viewpoint) in the array are offset or staggered. As a result, the shock absorbing members of every other or second row of the array are aligned. In this embodiment, theshock absorbing members 104 are all substantially identical. As can be best seen inFIGS. 2 and 5 , eachshock absorbing member 104 is roughly or generally parabolic in shape and has relief formations formed therein. In this embodiment, the relief formations are in the form of a plurality ofrelief grooves 120, in this example six (6)relief grooves 120, and a substantially cylindricalcentral recess 122. Therelief grooves 120 are substantially equally spaced about acentral axis 124 of theshock absorbing member 104 and extend radially with respect to thecentral axis 124. As best shown inFIG. 5 , three of therelief grooves 120 are of atype 120 a and three of therelief grooves 120 are of atype 120 b. Therelief grooves 120 a extend radially from thecentral recess 122 to anouter surface 126 of theshock absorbing member 104 and extend completely through theshock absorbing member 104 in the radial direction. Therelief grooves 120 b extend radially inward from theouter surface 126 towards thecentral recess 122 but only extend partially through theshock absorbing member 104 in the radial direction. In the axial direction, therelief grooves 120 a extend from a distal end or tip 128 of theshock absorbing member 104 towards abase 130 of theshock absorbing member 104. Therelief grooves 120 b extend in the axial direction from the base 130 towards thetip 128, ending at theouter surface 126 before reaching thetip 128. As will be appreciated, in another embodiment therelief grooves 120 b may extend radially outward away from thecentral recess 122. - Interlocking features or
elements 106 are provided about the periphery of thebody 102 at spaced locations. Each interlockingelement 106 is located adjacent arespective side surface 114 of thebody 102 and comprises an upwardly turned, L-shapedprotrusion 132 connected to theperipheral lip 118. Theprotrusion 132 extends laterally outward from theside surface 114 of thebody 102 and is adapted or configured to engage aperipheral lip 118 of an adjacent or neighbouringshock absorbing mat 100 to interlock adjacent or neighbouringshock absorbing mats 100 to one another. Each interlockingelement 106 extends lengthwise across theside surface 114 from which it projects, beginning near thecorner edge 134 of theside surface 114 and terminating adjacent the midpoint of theside surface 114. -
Supports 108 in the form ofsupport posts 136 andsupport ribs 138 also depend from thebody 102. Eachsupport post 136 is generally wave-shaped and depends from thecentral portion 116 of thebottom surface 112 of thebody 102. The support posts 136 are located adjacent the edges of thebottom surface 112 in gaps between theshock absorbing members 104 and theperipheral lip 118. Eachsupport rib 138 has a generally serpentine wall-like shape and extends downwardly from an interlockingelement 106, the adjacentperipheral lip 118 and thecentral portion 116. Thesupports 108 reinforce areas of theshock absorbing mat 100 devoid of theshock absorbing members 104, such as the corners (as shown inFIG. 6 ) and the edges of theshock absorbing mat 100, to provide stiffness uniformity across thetop surface 110 of theshock absorbing mat 100. - When a force with a downward component is applied to the
top surface 110 of theshock absorbing mat 100 as a result of an impact, theshock absorbing members 104 compress axially and expand laterally to provide shock absorption. The relief formations, specifically therelief grooves 120 andcentral recess 122 of eachshock absorbing member 104, provide space to accommodate the lateral expansion during axial compression and assist to reduce stresses within eachshock absorbing member 104. Additionally, as will be appreciated by one of ordinary skill in the art, the shock absorption characteristics of theshock absorbing mat 100 will depend on the shape and material of theshock absorbing members 104, among other factors. Providing therelief grooves 120 and thecentral recess 122 within theshock absorbing members 104 allows for greater customizability and control of these shock absorbing characteristics. - During use, one or more of the
shock absorbing mats 100 are placed on a base surface such as for example a floor surface. In the event that more than oneshock absorbing mat 100 is used, adjacent or neighbouringshock absorbing mats 100 are connected to one another via respective interlockingelements 106 and peripheral lips 118 (seeFIG. 6 ). Theshock absorbing mats 100 provide a substantially uniform and planar working top surface that is supported above the base surface by theshock absorbing members 104 and supports 108. As such, the base surface is provided with improved shock absorption characteristics and as such the transmission of noise and vibration through the base surface is mitigated. - Turning to
FIGS. 7 to 11 , another embodiment of a shock absorbing mat is shown and is generally identified byreference character 200. Theshock absorbing mat 200 is similar to theshock absorbing mat 100 previously described, with the exception of theshock absorbing members 204. In this embodiment, theshock absorbing members 204 havewider relief grooves 220 b that are circumferentially expanded about thecentral axis 124 to extend substantially between therelief grooves 120 a as compared torelief grooves 120 b of theshock absorbing members 104. Theshock absorbing members 204 are otherwise identical to theshock absorbing members 104 previously described. - Turning to
FIGS. 12 to 22 , another embodiment of a shock absorbing mat is shown and is generally identified byreference character 300. Themat 300 is of unitary construction and is formed of rubber material or other suitable material such as for example natural rubber, styrene-butadiene rubber (SBR), recycled rubber etc. Theshock absorbing mat 300 is generally square-shaped and comprises abody 302 having a generally planar, majortop surface 310, an oppositebottom surface 312 and four (4) peripheral side surfaces 314 extending between thetop surface 310 and thebottom surface 312. Thebottom surface 312 comprises a substantially planarcentral portion 316 surrounded by a downwardly extendingperipheral lip 318. Acutout 344 is provided in eachside surface 314 of thebody 302. At eachcutout 344, a plurality ofdetents 342 is formed in thebottom surface 312. - A plurality of spaced-apart
shock absorbing members 304 arranged in an array depend from thecentral portion 316 of thebottom surface 312. Theshock absorbing members 304 of adjacent rows (or columns depending on viewpoint) in the array are offset or staggered. As a result, the shock absorbing members of every other or second row of the array are aligned. In this embodiment, eachshock absorbing member 304 is substantially cylindrical in shape and has relief formations formed therein. In this embodiment, the relief formations are in the form of arelief groove 320 and a substantially cylindricalcentral recess 322. Therelief groove 320 extends circumferentially about acentral axis 324 of theshock absorbing member 304 and is concentric with thecentral recess 322 and anouter surface 326 of theshock absorbing member 304. In the axial direction, therelief groove 320 extends from thedistal end 328 of theshock absorbing member 304 to thebase 330 of theshock absorbing member 304. Therelief groove 320 andcentral recess 322 divide theshock absorbing member 304 into two (2) annular portions orcylindrical rings 340, namely innerannular portion 340 a and outerannular portion 340 b. Adistal end 328 a of the innerannular portion 340 a is recessed with respect to adistal end 328 b of the outerannular portion 340 b. - A pair of interlocking
elements 306 extends from eachside surface 314 of thebody 302. Each pair of interlockingelements 306 comprises an outwardly extending, L-shapedprojection 306 a and an inwardly extendingcomplimentary void 306 b. Thecomplimentary void 306 b is delimited by theperipheral lip 318, the plurality ofdetents 342, thecutout 344 and the portion of thebottom surface 312 at thecutout 344. Theprojection 306 a is adapted or configured to pass through thecutout 344 of an adjacent or neighbouringshock absorbing mat 300 and an upwardly turned end of theprojection 306 a is crenulated to engage thedetents 342 of the adjacent or neighbouringshock absorbing mat 300, to interlock theshock absorbing mats 300 to one another thereby to form a floor covering. - Supports in the form of
support posts 308 depend from thebody 302. The supports posts 308 are hollow and generally semi-circular in shape. Eachsupport post 308 extends downwardly from thecentral portion 316 of thebottom surface 312 and abuts theperipheral lip 318. The supports posts 308 are located or positioned to provide additional reinforcement in areas of theshock absorbing mat 300 devoid of theshock absorbing members 304 and theperipheral lip 318, to provide stiffness uniformity across the top surface of theshock absorbing mat 300. - When a force with a downward component is applied to the
top surface 310 of theshock absorbing mat 300 as a result of an impact, theshock absorbing members 304 compress axially and expand laterally to provide shock absorption. Therelief groove 320 andcentral recess 322 of eachshock absorbing member 304 provide space to accommodate this lateral expansion during axial compression and assist to reduce stresses within eachshock absorbing member 304. Additionally, as will be appreciated by one of ordinary skill in the art, the shock absorption characteristics of theshock absorbing mat 300 will depend on the shape and material of theshock absorbing members 304, among other factors.
