Abstract:
1. A reinforcement device comprising: a rail having a top wall, a bottom wall located corresponding to the top wall, and a sidewall extending between the top wall and the bottom wall, the sidewall having a first face and a second face on opposing sides thereof, the top wall, the bottom wall, and the first face of the sidewall defining a slide path, the sidewall configured to form upper and lower longitudinally extending offset-bend portions thereof to define an undulating cross-section of the rail, the undulating cross-section defining a recessed reinforcement path on the second face of the sidewall bounded by a first inner wall and a second inner wall respectively defined by the upper and lower offset-bend portions, and a connection wall extending between the first and second inner walls, the connection wall being recessed relative to a surrounding surface of the second face; a planar reinforcement member having first and second surfaces on opposing sides thereof, the reinforcement member being slidably retained in the reinforcement path of the rail in recessed manner against the connection wall, the reinforcement member thereby substantially filling the reinforcement path, with the first surface bearing against the connection wall, and an extension support bearing against the second surface of the reinforcement member to capture the reinforcement member against the rail, the extension support having a first flange, a second flange, and a first connection portion extending between the first flange and the second flange, the first flange, the second flange and the first connection portion defining an arm, the first flange and the second flange respectively engaging in displaceable manner the top wall and the bottom wall of the rail, wherein top and lower protrusions are disposed on the rail intermediately between the top and bottom walls of the rail to retain the reinforcement member therein, the top protrusion extending from the second face located adjacent to the first inner wall, the top protrusion reaching into the reinforcement path, the lower protrusion extending from the second face located adjacent to the second inner wall, the lower protrusion reaching into the reinforcement path, the reinforcement member contacting the top and lower protrusions so that the reinforcement member remains movably connected to the reinforcement path of the rail.
