Abstract
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.
Claims15
A plurality of riser barriers for a handrail of a staircase or ramp, the handrail being an elongated cylinder supported at a height above the staircase or ramp by a plurality of external supports, each of the riser barriers comprising:
- an extender portion and a riser portion, wherein the plurality of riser barriers are solely supported by the elongated cylinder at a first set of spaced-apart locations along the elongated cylinder,
- wherein the plurality of external supports support the elongated cylinder at a second set of spaced-apart locations along the elongated cylinder, no location in the second set coinciding with any location in the first set, each riser portion being generally vertical and each extender portion being generally horizontal,
- wherein each of the extender portions has a length between a proximal end and a distal end, each of the proximal ends having attached thereto an arcuate portion that is adapted and fastened to the curvature of the bottom of the cylinder, and each of the distal ends being fastened to a respective riser portion at a position below the height of the elongated cylinder,
- wherein the length of each of the extender portion holds a respective riser portion a horizontal distance away from the elongated cylinder to permit passage of a hand along the elongated cylinder, and
- wherein each of the riser portions has a length that extends above the height of the elongated cylinder so as to deter sliding along the elongated cylinder.
