Abstract:

Embodiments herein provide a modular gutter for use by bicycles and other conveyances. When utilized, a conveyance may be guided along the gutter either by an individual on the conveyance or adjacent to it, whether up or down the gutter. The gutter may be manufactured in various lengths and arrangements, and additionally, the components of the gutter are designed to permit multiple subunits to be coupled to form longer gutters. Alternatively, the gutters may be cut to a desired length should the manufactured length be too long. Thus, the gutter may be sized for any of a variety of staircases. The gutter may be removably installed on existing staircases without the need to redesign or reconstruct the staircase.
