POOL CLEANING TOOL Filed Dec. 26, 1961 .FZTG. 3. /2
INVENTOR. L000 wco "M BURA TT/ Arroeusr United States Patent 3,192,678 POOL CLEANING TOOL Ludovico N. Buratti, 7542 New Castle Ave., Reseda, Caiif. Filed Dec. 26, 1961, Ser. No. 162,017 1 Claim. (Cl. 51-390) This invention relates to a pool cleaning tool and, more particularly, to a tool adapter to easily and readily remove stains and other deposits from the white plaster coating of conventional swimming pools.
It is well known to those skilled in the art that the white plaster coating of swimming pools is particularly susceptible to unsightly stains such as rust, algae, and the like.
Prior art expedients utilized to remove such stains have included emerystone and the like which have necessitated direct application to the stain by hand. Even then, such expedients have been relatively ineffective.
It is, therefore, an object of my invention to provide a pool cleaning tool which is adapted for the remote removal of such stains.
Another object of my invention is the provision of a pool cleaning tool of the aforementioned character which includes an elongated body, a demountable covering of abrasive material on said body, and a clamp for maintaining said abrasive material in overlying relationship with said body.
A further object of my invention is the provision, in a tool of the aforementioned character, of a body having a curvilinear supporting surface for said abrasive material which has angular extremities facilitating its application in relatively confined spaces.
An additional object of my invention is the provision of a cushion between said body and said abrasive material.
A further object of my invention is the incorporation of clamping means in said body adapted to tension said abrasive material on said body.
Other objects and advantages of my invention will be apparent from the following specification and accompanying drawing which is for the purpose of illustration only, and in which:
FIG. 1 is a side elevational view;
FIG.2 is an isometric view of the pool cleaning tool of the invention;
FIG. 3 is a fragmentary, sectional View illustrating an extremity of the device;
FIG. 4 is a vertical, sectional view taken on the broken line 4-4; and
FIG. 5 is a vertical, sectional view similar to FIG. 4, prior to the adjustment of the clamping means of the invention.
Referring to the drawing and, particularly, to FIG. 1 thereof, I show a pool cleaning tool constructed in accordance with the teachings of my invention and including an elongated body 12 which is of semi-circular configuration and which has clamping means 14 associated therewith. The clamping means 14 is adapted to maintain a flexible covering of abrasive material 16 in operative relationship with the elongated body 12.
The elongated body 12 may be fabricated from any desired material, such as an aluminum extrusion, a plastic extrusion, or the like. The body 12 provides a semicircular exterior supporting surface 18 to which is secured,
as by means of a suitable adhesive, a cushion 20 of resilient material such as foam rubber, polyurethane foam, or the equivalent.
If desired, the opposite extremities of the body 12 may be cut to an acute angle, as at 24, to insure that the abrasive material 16 will contact relatively inaccessible sur faces such as the corner 26 of a pool, as best shown in FIG. 3 of the drawing.
The clamping means 14 incorporated in the pool cleaning tool 10 includes an elongated rectangular plate 32 having beveled side edges 34 adapted to co-operate with corresponding beveled side edges 36 which define the outer extremities of lands 38 adapted to receive and support the plate 32 and the associated extremities 40 of the abrasive material 16.
The plate 32 is maintained in operative relationship with the body 12 of the tool 10 by the provision of a pair of bolts 42 whose upper extremities project beyond the upper edges of the body 12 and are adapted to protrude through corresponding openings 44 in the plate 32. When the plate 32 is installed thereupon, the upper extremities of the bolts 42 are engaged by wing nuts 46 or similar fasteners adapted to draw the plate 32 downwardly upon the associated surfaces of the lands 38 and the associated extremities 40 of the abrasive material.
Secured to the upper surface of the plate 32 intermediate the bolt holes 44 is a bracket 48 which is adapted to receive the lower extremity of a pole 52 whereby the tool 10 may be manipulated under the surface of the water in a pool to remove stains therefrom. The length of the body 12 may be determined by the particular application for which the tool 10 is intended and, thus, various sizes of the tool 10 may be provided to cope with different applications.
The process of installing a covering of abrasive material 16 in operative relationship with the body 12 entails the formation of a blank having tapered side edges adapted to conform to the angularly configured extremities 24 of the body 12. The free extremities 40 of the abrasive material are then wrapped about the upper edges of the body 12 and are engaged by the under surface of the plate 32, as best illustrated in FIG. 5.
Therefore, when the wing nuts 46 are rotated to urge the plate 32 downwardly, the free extremities 4B are clamped between the beveled edges 34 of the plate 32 and the beveled sides 36 of the lands 38, thus causing the abrasive material 16 to be drawn tightly into engagement with the associated cushion 20. The provision of the cushion 20 permits the abrasive material 16 to conform to irregularities in the pool surface and, thus, results in maximum engagement of the abrasive material 16 with said surface.
I thus provide by my invention a pool cleaning tool which is characterized by its ease of application to stained surfaces of a pool. Furthermore, the abrasive material mounted thereupon is easily replaced and is tightly drawn into operative relationship with the body of the tool by the clamping means of the tool.
While the invention has been described by means of specific examples and specific embodiments the invention is not limited thereto. since obvious modifications and variations will occur to those skilled in the art without departing from the spirit and scope of the invention as defined by the appended claims.
In a pool cleaning device, the combination of: an elongated body of semi-ciylindrical cross section, said body having angularly oriented extremities adapted to permit its insertion into areas of reduced accessibility, said body also having a pair of lands formed therein, each of said lands having beveled side edges at their outer extremities; a plate having a pair of beveled side edges on said lands; an abrasive covering on said body extending over said lands; a resilient cushion between said covering and said body to permit said covering to conform to irregularities in the pool surface; and means for clamping said plate against said lands to draw said covering tightly into en gagement with said cushion.
