Abstract: A bumper apparatus includes a roller rack and rack fasteners for mounting the roller rack vertically along a dock structure; a bumper assembly having a buoyant structure having sufficient buoyancy to cause the bumper assembly to rise and fall with the water surface and thus with the tide and with any adjacent water vessel; and a rack engaging structure slidably interconnecting the roller rack and the bumper assembly so that the bumper assembly is slidable vertically relative to the roller rack. The roller rack preferably includes a spaced apart upright pair of opposing first and second mounting rails; and a longitudinal series of substantially horizontal cylindrical rollers mounted on individual roller axles extending between and connected to the first and second mounting rails so that the rollers protrude forwardly from the mounting rails.

Abstract: A mailbox includes a box having a box wall with a panel opening, the panel opening being fitted with a translucent panel marked with indicia; an electric power source; a light source secured relative to the box and positioned to radiate light from within the box through the translucent panel to enhance visibility of the indicia; and a light source circuit electrically interconnecting the power source and the light source.

Abstract: A gate supporting assembly for a truck bed having a bed bottom wall, a bed wall and a bed gate, the bed gate being pivotally secured to the bed to pivot upwardly to close the bed and to pivot downwardly to become substantially horizontal and thereby open the bed, includes a gate supporting mechanism releasibly supporting the gate at an angle substantially midway between horizontal and vertical, to retain cargo while minimizing drag, increasing fuel efficiency, providing air foil traction enhancement while leaving the rear bumper exposed and functional.
