US 2026/0062923 A1 · CONNECTION SYSTEM FOR PORTABLE FLOORING

Abstract

At each straight edge of a plywood section which is to be coupled to an adjacent plywood section, one half of a coupling structure is provided and the other half of the coupling structure is provided to the other plywood section which is to be coupled thereto. A system is provided which only requires a single set screw to hold elongated coupling halves together while absolutely preventing warpage or displacement of plywood sections with respect to one another. Thus, a ramp structure is incorporated into a recess which results in the vertical dimension of a tongue substantially matching the vertical dimension of the recess when the coupling halves are coupled together. The ramp structure best facilitates sliding the coupling halves into connection and a single set screw can be advanced to hold the coupling halves together with assurance that no warpage or misaligning will take place.

Dependent claims

A coupling system for portable flooring comprising:

a) a coupling half comprising an elongated body having a top surface, a bottom surface, a first side, and a second side;
b) said first side including a first recess configured to receive an edge of a flooring section, said second side including a second recess with an opening at said second side;
c) said second recess having a substantially flat bottom wall and a top wall having a ramp surface reducing a top to bottom dimension of said second recess in a direction from said second recess opening toward said first side.

A coupling system for portable flooring comprising:

a) a first coupling half comprising an elongated body having a top surface, a bottom surface, a first side, and a second side;
b) said first side including a first serrated recess configured to receive an edge of a flooring section, said second side including a second recess with an opening at said second side;
c) said second recess having a substantially flat bottom wall and a top wall having a ramp surface reducing a top to bottom dimension of said second recess in a direction from said second recess opening toward said first side;
d) a second coupling half comprising an elongated body having a top surface, a bottom surface, a first side, and a second side, said first side of said second coupling half including a first serrated recess configured to receive an edge of a further flooring section, said second side of said second coupling half including a tongue extending in a direction away from said first side, said tongue having an upwardly angled bent distal end configured to be received within said second recess of said first coupling half to couple together said first and second coupling halves while maintaining said top surfaces of said coupling halves in a substantially common plane.
