20120005973 | HANDRAIL FOR STAIRCASE OR RAMP - An improved handrail for a staircase or ramp. In one embodiment, the handrail includes an elongated member such as a cylinder or bar that spans the length of the staircase or ramp and a riser barrier. The riser barrier has an extender portion and a riser portion. The extender portion of the riser barrier keeps the elongated member a sufficient distance horizontally from the riser portion that a person can slide his or her hand on the rail without interference. The riser portion projects vertically a sufficient distance above the elongated member to deter sliding down the elongated member. Thus, sliding on the member is deterred, while the function of the cylinder as a handrail is preserved. | 01-12-2012 |
