Abstract

Apparatus movable over an approach surface and down a lane surface includes a shield plate which has a forward edge positionable to prevent cleaning fluid from nozzles from reaching the approach surface behind a foul line while permitting cleaning of the lane surface beyond the foul line. A pair of forward wheels are used for support during movement over the approach surface and are arranged to drop down into side gutters to engage support rollers with the lane surface and to also drop a fluid pick-up head into engagement with the approach surface at the foul line.

Claims

1. Apparatus for cleaning a bowling alley lane, wherein one end of a lane surface and a coplanar approach surface are contiguous along a foul line and wherein a pair of gutters extend along opposite sides of said lane surface from said approach surface to the opposite end of said lane surface, said apparatus comprising:

a frame structure, roller means for supporting said frame structure for movement in a forward direction over said approach surface and along said lane surface to said opposite end thereof and then in a rearward direction back to said approach surface, fluid-applying means on said frame structure for applying a cleaning fluid onto said lane surface, and suction means supported from said frame structure and including pick-up head means extending across the full width of said lane surface to remove cleaning fluid applied by said fluid-applying means, said fluid-applying means and said suction means being constructed and arranged for preventing application of cleaning fluid to said approach surface behind said foul line while permitting application and removal of cleaning fluid to and from said lane surface ahead of said foul line, wherein said fluid-applying means includes fluid-intercepting wall means supported on said frame structure and having a forward edge extending transversely across said lane surface, said wall means being effective to intercept fluid and prevent fluid from reaching portions of said lane surface positioned behind said forward edge of said wall means, and said forward edge forming a forward-most edge portion of said apparatus and being positioned for view by an operator of said apparatus to facilitate accurate positioning of said forward edge relative to said foul line.

2. Apparatus for cleaning a bowling alley lane as defined in claim 1, wherein said fluid-applying means includes nozzle means spaced upwardly from said wall means and behind said forward edge thereof and arranged for projecting fluid forwardly beyond said forward edge onto said lane surface.

3. Apparatus for cleaning a bowling alley lane as defined in claim 2, wherein said wall means includes a generally horizontal plate extending forwardly from said frame structure and detachably secured thereto.

4. Apparatus for cleaning a bowling alley lane, wherein one end of a lane surface and a coplanar approach surface are contiguous along a foul line and wherein a pair of gutters extend along opposite sides of said lane surface from said approach surface to the opposite end of said lane surface, said apparatus comprising:

a frame structure, roller means for supporting said frame structure for movement in a forward direction over said approach surface and along said lane surface to said opposite end thereof and then in a rearward direction back to said approach surface, fluid-applying means on said frame structure for applying a cleaning fluid onto said lane surface, and suction means supported from said frame structure and including pick-up head means extending across the full width of said lane surface to remove cleaning fluid applied by said fluid-applying means, said fluid-applying means and said suction means being constructed and arranged for preventing application of cleaning fluid to said approach surface behind said foul line while permitting application and removal of cleaning fluid to and from said lane surface ahead of said foul line, wherein said fluid-applying means includes fluid-intercepting wall means supported on said frame structure and having a forward edge extending transversely across said lane surface, said wall means being effective to intercept fluid and prevent fluid from reaching portions of said lane surface positioned behind said forward edge of said wall means, wherein said fluid-applying means includes nozzle means having a fluid distribution pattern which is such as to include a primary region extending across said lane and having a relatively high fluid density and a marginal region behind said primary region and having a density which gradually tapers off from that of said primary region, said forward edge of said wall means being so positioned relative to said primary and marginal regions as to insure that adequate fluid will reach portions of said lane surface which are positioned forwardly from said forward edge while preventing fluid from reaching portions of said lane surface which are positioned behind said forward edge and while also limiting the volume of fluid intercepted by said wall means.

5. Apparatus for cleaning a bowling alley lane wherein one end of a lane surface and a coplanar approach surface are contiguous along foul line and wherein a pair of gutters extend along opposite sides of said lane surface from said approach surface to the opposite end of said lane surface, said apparatus comprising:

a frame structure, roller means for supporting said frame structure for movement in a forward direction over said approach surface and along said lane surface to said opposite end thereof and then in a rearward direction back to said approach surface, fluid-applying means on said frame structure for applying a cleaning fluid onto said lane surface, and suction means supported from said frame structure and including pick-up head means extending across the full width of said lane surface to remove cleaning fluid applied by said fluid-applying means, said roller means comprising support rollers journaled on said frame structure and arranged for supporting engagement with said lane surface, and guide rollers journaled on said frame structure and arranged for engagement with surface portions of said gutters adjacent opposite sides of said lane surface to limit transverse movement of said apparatus during longitudinal movement over said lane surface.

6. Apparatus for cleaning a bowling alley lane as defined in claim 5, wherein said roller means further comprise wheels journaled on said frame structure and arranged for supporting engagement with said approach surface, said wheels including pair of forward wheels arranged to drop down into said gutters and to drop said support rollers into engagement with said lane surface.

7. Apparatus for cleaning a bowling alley lane as defined in claim 6, wherein said pair of forward wheels are so positioned in forwardly spaced relation to said pick-up head means as to drop said pick-up head means into engagement with said approach surface behind said foul line when said pair of forward wheels drop into said gutters.

8. Apparatus for cleaning a bowling alley lane as defined in claim 7, wherein said fluid-applying means and said suction means are constructed and arranged for preventing application of cleaning fluid to said approach surface behind said foul line while permitting application and removal of cleaning fluid to and from said lane surface ahead of said foul line.

9. Apparatus for cleaning a bowling alley lane surface wherein a coplanar approach surface and one end of said lane surface meet at a foul line and wherein a pair of gutters extend along opposite sides of said lane surface from said approach surface to the opposite end of said lane surface, said apparatus comprising:

a frame structure, roller means for supporting said frame structure for movement in a forward direction over said approach surface and along said lane surface to said opposite end thereof and then in a rearward direction back to said approach surface, fluid-applying means on said frame structure for applying a cleaning fluid onto said lane surface, and suction means supported from said frame structure and including pick-up head means extending across the full width of said lane surface to remove cleaning fluid applied by said fluid-applying means, said pick-up head means comprising forward and rearward blade members of resilient material for extending across said lane surface and outer and inner support members for supporting said blade members, said support members having cross-sectional configurations of generally inverted U-shaped form, each including a pair of forward and rearward side walls extending downwardly from forward and rearward edges of a horizontal wall, said forward blade member having an upper portion clamped between said forward walls of said inner and outer support members and said rearward blade member having an upper portion clamped between said rearward side walls of said inner and outer support members.
