<p>A FOOT MAT IS COMPOSED OF A PLURALITY OF ELONGATED RAIL MEMBERS (20) ARRANGED CLOSELY ADJACENT EACH OTHER WITH A GAP BETWEEN EACH ADJACENT PAIR OF RAIL MEMBERS. EACH RAIL MEMBER IS OF UNIFORM CROSS SECTION ALONG ITS LENGTH AND INCLUDES A BODY PORTION (22) AND A PAIR OF SPACED-APART DEPENDENT LEG PORTIONS (27). AN ELONGATED TREAD MEMBER (100, 104, 106, 108 OR 110) IS RECEIVED ON THE UPPER SURFACE OF EACH RAIL MEMBER. EACH ADJACENT PAIR OF RAIL MEMBERS IS JOINED BY AN EXTRUDED PLASTIC CONNECTOR MEMBER (30) THAT HAS A CONNECTING WEB PORTION (32) AND A PAIR OF GENERALLY U- SHAPED SOCKET PORTIONS (38). EACH LEG PORTION OF EACH RAIL AND EACH SOCKET PORTION OF EACH CONNECTING MEMBER ARE CONFIGURED TO SNAP-FIT TOGETHER AND HAVE INTERENGAGING SHOULDERS (27S AND 38S) THAT ARE CONFIGURED TO RETAIN THE LEG PORTION IN THE SOCKET PORTION. EACH RAIL MEMBER HAS A PAIR OF LATERALLY SPACED-APART DEPENDENT ELONGATED ANCHOR TAB PORTIONS (28), EACH OF THE ANCHOR TAB PORTIONS ENGAGING A SOCKET PORTION OF ONE OF THE TWO CONNECTOR MEMBERS TO WHICH THE RAIL MEMBER IS COUPLED AND HAVING BEEN PLASTICALLY DEFORMED TO GRIP THE SOCKET PORTION SO AS TO PREVENT LONGITUDINAL DISPLACEMENT OF THE RAIL MEMBER RELATIVE TO THE TWO CONNECTOR MEMBERS.</p> |
