Abstract
A moveable gutter for a bowling lane is disclosed. The gutter includes a bumper surface that functions as a bumper when said inner edge is raised from a lower position to a fixed upper position higher than the adjacent lane surface. One or more illumination sources may be disposed along the surface of the gutter and bumper surface. A portion of said bumper surface is approximately parallel with the surface of a bowling ball on the bowling lane when the upper surface is in the upper position.
Claims8
A moveable gutter with illumination sources comprising:
- a gutter having a concave upper gutter surface, said upper surface having an inner edge adjacent to the bowling lane and an outer edge distal from the bowling lane;
- said inner edge of said gutter surface comprising a bumper and said outer edge being rotatably mounted such that said gutter may be raised from a lower position to a fixed upper position higher than the adjacent lane surface;
- at least one illumination source disposed longitudinally about said upper surface, wherein said at least one illumination source comprises a self-illuminating fluorescent material that glows in the dark when exposed to light, said at least one illumination source is disposed within reverse tapered grooves running lengthwise along said upper surface, said at least one illumination source is formed in a cross-sectional shape corresponding to said tapered grooves, and the upper surface of said at least one illumination source comprises a rounded cross sectional shape extending slightly above the surface of the gutter, thereby forming longitudinal ridges along the length of the gutter;
- and
- a plurality of gutter ridges formed directly in said upper surface, each of said plurality of gutter ridges having a rounded surface, wherein a bowling ball rolling in the gutter contacts only the rounded surface of said plurality of gutter ridges when said gutter is in said lower position.

A moveable gutter for a bowling lane comprising:
- moveable gutter means having a concave upper gutter surface, said upper surface having an inner edge adjacent to the bowling lane and an outer edge distal from the bowling lane;
- said inner edge of said gutter surface further comprising bumper means;
- means for rotating said moveable gutter means from a lower position to a fixed upper position higher than the adjacent lane surface;
- and
- illumination means disposed about said upper surface, wherein said illumination means comprises a self-illuminating fluorescent material that glows in the dark when exposed to light, said illumination means is disposed within reverse tapered grooves running lengthwise along said upper surface, said illumination means is formed in a cross-sectional shape corresponding to said tapered grooves, and the upper surface of said illumination means comprises rounded cross sectional shape extending slightly above the surface of the gutter, thereby forming longitudinal ridges along the length of the gutter;
- and
- a plurality of gutter ridges formed directly in said upper surface, each of said plurality of gutter ridges having a rounded surface, wherein a bowling ball rolling in the moveable gutter means contacts only the rounded surface of said plurality of gutter ridges when said moveable gutter means is in said lower position.
