Description

SAND CLEANING TOOL

BACKGROUND OF THE INVENTION

Field of the Invention:

The present invention relates to a cleaning tool, and more particularly, a sand cleaning tool.

Description of the Prior Art;

Numerous innovations for ground-debris cleaning devices have been provided in the prior art that will be described. Even though these innovations may be suitable for the specific individual purposes to which they address, however, they differ from the present invention.

A FIRST EXAMPLE, U.S. Patent Office Document No. 3,000,448, Issued on Sept. 19, 1961, to Piatt, et al . teaches a beach sand cleaning machine including a frame, wheels supporting the frame, a succession of rakes movably carried by the frame and operable to successively enter and continuously comb a strip of the stand along which the machine is advanced, an apparatus for mounting the rakes for movement into the sand and then upwardly to elevate debris separately from the sand, apparatus for actuating the rakes in such movement, and a hopper carried by the frame and positioned to receive the debris elevated by the rakes. The rakes are formed of flexible tines having an essentially comb arrangement and are unencumbered and spaced to pass the sand so that substantially none of the sand is elevated to the hopper. The tines have looped inner portions connected to the mounting apparatus,

A SECOND EXAMPLE, U.S. Patent Office Document No. 3,146,831, Issued on Sept. 1, 1964, to McConnell teaches a rake for maintenance of sand traps and putting greens of golf courses. The rake includes a head including an inflexible, reticulate, and generally oblong body portion of substantially concavo-convex shape in cross section. One edge of the concavo-convex body portion is reversely bent to provide an extension terminating in teeth adapted to penetrate and loosen the sand of a stand trap. The sand is rolled, by virtue of the reticulate construction of the body portion, to fluff and level the sand. A handle is fixed to the head. The handle is disposed at such an angle to the head that the terminal teeth of the body portion are substantially vertical to the ground. When the rake is held in position for use in a stand trap, the rake is turned over to effect engagement of the convex portion of the reticulate and oblong body portion with the green. The handle extends upwardly at approximately the same angle for the two different raking operations, thereby facilitating manipulation of the rake by the user.

A THIRD EXAMPLE, U.S. Patent Office Document No. 3,979,146, Issued on September 7, 1976, to Berg teaches a beach cleaning apparatus that includes a generally U-shaped bracket that opens downwardly, a handle attached to the bracket to manually pull the bracket forwardly, an open mesh bag, a fastener mechanism for releasably securing the adjacent parts of the mouth portion of the bag to the bracket, a knife blade extending between the legs of the bracket, and a retainer bar secured to the bracket and knife blade for retaining the lower edge portion of the mouth of the bag therebetween. The mesh of the bag is of a size to permit passage of sand and small stones therethrough, but retain larger objects within the bag.

A FOURTH EXAMPLE, U.S. Patent Office Document No. 4,828,690, Issued on May 9, 1989, to Montez teaches a hand tool having a tapered wedge head, an entrapment mesh supported by a carriage structure and cantilevered from the wedge head, and a handle adjustably coupled to the carriage structure. The tapered wedge head ramps materials, such as sand and soil, into the entrapment mesh. The entrapment mesh is fixed to the carriage structure so that the face and opposed sides of the carriage structure are open. The entrapment mesh is cantilevered from the wedge head to prevent contact of the mesh with the ground.

A FIFTH EXAMPLE, U.S. Patent Office Document No. 5,205,122, Issued on April 27, 1993, to Wong teaches a combination sand rake and shovel providing the ability to clean sandy with a tool having two configurations. When configured as a shovel, the debris may^¬ be lifted directly from the sand. When configured as a rake, the debris can be screened in a direction parallel to the grounds surface . A SIXTH EXAMPLE, U.S. Patent Office Document No. 6,857,479,

Issued on February 22, 2005, to Ohzeki, et al . teaches a beach cleaner for recovering waste while moving in a towed state by a traction vehicle. A grating-like portion scoops up waste present in front of the beach cleaner as the beach cleaner is moved and a reticulate portion that is formed behind the grating-like portion to hold waste. As the beach cleaner is moved, waste present in front of the beach cleaner is scooped up onto the grating-like portion and is held with the reticulate portion formed behind the grating-like portion. Sand that is scooped up together with the waste is allowed to drop through the gaps in the grating-like portion.

A SEVENTH EXAMPLE, U.S. Patent Office Document No. 8,689,533, Issued on April 8, 2014, to Abughazaleh teaches a lawn rake or lawn rake attachment providing a capture structure that cooperates with the tines of a lawn rake to increase the collection of small leaves and debris with each stroke of the rake. More specifically, the capture structure provides a broad surface, preferably, spanning the width of the rake and positioned an effective distance trailing behind the rake tine structure. In operation of the lawn rake equipped with the capture structure, during the course of a stroke of the rake the rake tines stir up the small leaves in or on the lawn grass. The stirring-up action propels the leaves a distance up above the ground before they fall back on the rake stroke trail. The trailing rake capture structure intercepts the airborne leaves and holds them at its surface while the rake is in a forward raking motion.

AN EIGHTH EXAMPLE, Article published on March 23, 2011 by Malgari teaches a manual tool to clean sandy areas. The manual tool solves the problem of keeping a sandy home-front clean and safe. One sweep makes either a beach club ready to welcome costumers or an isolated beach clean.

It is apparent now that numerous innovations for ground- debris cleaning devices have been provided in the prior art that adequate for various purposes. Furthermore, even though these innovations may be suitable for the specific individual purposes to which they address, accordingly, they would not be suitable for the purposes of the present invention as heretofore described.
