A portable overlapping secured mat system with uniformly sized plastic mats joined together to form structural support surface for use by persons or equipment. The mats' edges have recessed upper and lower lips with finger projections extending from the upper lips sized to fit into holes of adjacent mats' lower lips securing the mats together when the front edge of the finger projections are moved into a recesses of the back wall of the hole.

Overlapping secured mat system

An mat system with each mat having sloping lips which overlap with an adjacent mat's sloping lips and are secured by interlocking joints in the mats' lips and/or by captive locking pins to form an easily assembled and interconnected flat surface. In use, opposing ledges forms a slot within holes in the top overlapping lips to receive a captive locking pin. The pin is captive by mid body prongs which fix underneath the ledges in a mat's upper lip's holes, and the pin locks and unlocks with rotary turning of the pin resulting in the pin's keeper feet fixing underneath the similar ledges in the holes of the lower lip of an adjacent mat.

Interlocking mat

A fastening device having a pin with an enlarged head and a central longitudinal bore to receive a rod having a head with a drive receiving recess and a footed keeper. The pin and rod have adjacent surfaces that aid in the prevention of turning relative to each other. In use, the pin, with the footed keeper in alignment, is inserted to aligned openings in overlapping maps used in roadways and a tool is used to turn the keeper a quarter turn to prevent the pin from coming out of the opening and securing the mat.
