a therapeutic device includes a mat 10 having a first surface 12 , fig1 and 5 , and a second surface 14 opposite the first surface 12 . a plurality of pressure point fingers 16 extend from the second surface 14 in a substantially dense array . the mat 10 and the pressure point fingers 16 are formed of a suitable synthetic material . the mat 10 and the fingers 16 are substantially rigid to resist flexing or distortion . an elongated groove 13 is formed in surface 12 along one or more edges 13 a of mat 10 . each pressure point finger 16 , see also fig3 , includes a tip 16 a , a base 16 b and a shaft 16 c . the shaft 16 c tapers outwardly from the tip 16 a to the base 16 b . the base 16 b has a width dimension indicated as 16 w , such that the base 16 b is of a greater width than the tip 16 a . each shaft 16 c has a height dimension 16 h from the base 16 b to the tip 16 a . the height dimension 16 h of each shaft 16 c being fractionally greater than the width dimension 16 w of the base 16 b . however , both the height 16 h and the width 16 w are about 0 . 125 inches or less . thus , the pressure point fingers 16 are substantially rigid to resist flexing . each tip 16 a is substantially tapered but is slightly rounded . this construction is sufficient to stimulate therapeutic treatment while resisting skin penetration . the pressure point fingers 16 , see fig1 a , 2 a - c and 3 - 4 , may be of varying geometry . for example , the pressure point finger 16 of fig3 , includes a base 16 b having a circular cross - sectional shape , whereas the pressure point finger 16 of fig2 a includes a base 16 b having an oval cross - sectional shape . in fig2 b and 2 c , the pressure point fingers 16 have a base 16 b including a triangular cross - sectional shape and a rectangular cross - sectional shape , respectively . it is illustrated in fig1 a , that the pressure point fingers 16 are substantially equally spaced apart linearly and laterally as indicated by the similar distance dimensions 16 s . finally , as described above , the pressure point finger 16 of fig4 illustrates the rigidity of each finger 16 enabling resistance to pressure acting thereon as indicated by a force designated 16 f . a connector 20 , fig5 , 6 and 7 is provided as a means for connecting an edge 13 a of one mat 10 to an edge 13 a of an adjacent mat 10 . the connector 20 is preferably extruded and includes a first flange 22 and a second flange 24 connected to and spaced from the first flange 22 by means of a web 26 . the first and second flanges 22 , 24 , respectively , form a pair of opposed gaps 22 a , 22 b on opposite sides of the web 26 . the first flange 22 is of a greater width than the width of the second flange 24 . the second flange 24 includes a pair of elongated ribs 28 extending into each gap 22 a , 22 b . the elongated ribs 28 may be replaced by a row of protrusions if desired , however , the continuous , elongated rib 28 is preferred . connection of a mat 10 to the connector 20 is best illustrated in fig5 . one gap 22 b of connector 20 is shown empty to receive a mat 10 , and the opposite gap is shown engaged with a mat 10 . groove 13 receives a rib 28 when the mat edge 13 a nests against web 26 . manual pressure may be applied to either or both flanges 22 , 24 to seat rib 28 into groove 13 in an interference fit for easy attachment and detachment . although illustrative embodiments have been shown and described , a wide range of modification , change and substitution is contemplated in the foregoing disclosure and in some instances , some features of the embodiments may be employed without a corresponding use of other features . accordingly , it is appropriate that the appended claims be construed broadly and in a manner consistent with the scope of the embodiments disclosed herein .
a mat section can be connected to one or more additional mat sections to provide a desired size combination of the mat sections . one mat section can be used singly or interconnected with an adjacent one or more mat section by use of a connector member such that the adjacent mat sections can be connected together . each mat section includes an array of pressure point fingers .
