Description

CROSS REFERENCE TO RELATED APPLICATION

This application takes the benefit of and claims priority to U.S. Provisional Application Ser. No. 62/362,272 filed on Jul. 14, 2016, the contents of which are herein incorporated by reference.

FIELD OF THE INVENTION

The present invention generally relates to tools, and more particularly, to a one piece forged floor scraper designed to retain both 2mm and 4mm scraper blades.

BACKGROUND OF THE INVENTION

Floor scrapers, also known as floor strippers are used to remove tile, glue, wood, etc. from the floors. Through the years floor scrapers have taken on many changes in shape, size, function, and design. Many present floor scrapers consist of a straight steel tube handle with some having a rubber or special designed hand grip around it. At the working end, the tube is connected to a steel holder, known as a scraper head. The scraper head holds the scraper blade. Typical conventional floor scraper designs use standard scraper blades that are usually replaceable. Blades typically range in size but the standard 8″ scraper blade is commonly utilized. The scraper blade is attached to the scraper head by screws and a flat plate that mates with the scraper head.

In certain aspects, floor scrapers are designed with a broad blade cutting tool having a shank adapted for insertion into the bushing portion of a power-driven hammer mechanism, such as an air-operated hammer, for cutting asphalt pavement.

Further, many of these floor scrapers and cutter mechanisms comprise of multiple parts that require the user to assemble the parts before use.

SUMMARY OF THE INVENTION

The instant apparatus, as illustrated herein, is clearly not anticipated, rendered obvious, or even present in any of the prior art mechanisms, either alone or in any combination thereof. Thus, the several embodiments of the instant system are illustrated herein.

In one aspect, the present apparatus introduces a novel floor scraper mechanism comprising a one piece forging design.

Another aspect of the present apparatus introduces a new floor scraper mechanism comprising a one piece forging design, with a working end wherein the working end may retain both 2 mm and 4 mm scraper blades. In yet another aspect, the system provides a new floor scraper that is user friendly and easy to utilize.

Yet another aspect of the present apparatus introduces a new floor scraper that provides easy removal of floor coverings such as tile, carpet, adhesives and more.

Another aspect of the present apparatus introduces a floor scraper with an innovative head design which helps to prevent shearing off of the bolt heads as an edge portion disposed for a blade to rest against is introduced. Further, the floor scraper's all steel design produces a long life for the tool and a protective coating prevents corrosion and rust.

In addition, an aspect of the present apparatus introduces a floor scraper that has increased efficiency and higher durability.

In one aspect of the present invention, the floor scraper mechanism comprises of a hex shank floor scraper system, wherein the hex shank may be used to attach the floor scraper to a series of mechanical instruments or prime motivator systems to create vibration onto the flooring or other surface.

Realizing one aspect of the apparatus is a new floor tool that provides an efficient and durable floor scraper that comprises a one piece forging design and wherein the working end of the floor scraper mechanism may retain both 2mm and 4mm scraper blades. The new floor scraper is user friendly and easy to utilize, as well as, the innovative head design helps to prevent shearing off of the bolt heads and the all steel design produces a long life for the tool. In addition, a protective coating prevents corrosion and rust.

There has thus been outlined, rather broadly, the more important features of the versatile hex shank floor scraper system embodiments in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated.

DETAILED DESCRIPTION OF THE DRAWINGS

The detailed description set forth below in connection with the appended drawings is intended as a description of presently-preferred embodiments of the system and does not represent the only forms in which the present system may be constructed and/or utilized. The description sets forth the functions and the sequence of steps for constructing and operating the apparatus in connection with the illustrated embodiments. However, it is to be understood that the same or equivalent functions and sequences may be accomplished by different embodiments that are also intended to be encompassed within the spirit and scope of the invention.

Referring now to the figures to better illustrate the present apparatus, FIG. 1 exemplifies a perspective view of one embodiment of the floor scraper mechanism 10 fully assembled and functional. The floor scraper mechanism comprises an upper shank portion 12, a handle portion 14, and a working end portion 30 comprising a steel holder 18 or scraper head, and a scraper blade device 20. The steel holder 18 comprises a set of attachment mechanisms 16, such as flange bolts and flange nuts, and retains the scraper blade device 20. Herein, the upper shank portion 12 may comprise of a one and one-eighth hexagon-shaped shank.

FIG. 2 illustrates a bottom view of the floor scraper mechanism 10, wherein the scraper blade device is removed so that the working end portion 30 and the scraper holder 18 is fully visible. Again, the upper shank portion 12 has an upper portion 34 preferably of hexagonal shape and adapted to fit into the bushing portion of a known type of power operated hammer. The hex shank portion 34 terminates in a collar 32 which functions to lock the tool into the bushing portion of the power operated hammer.

Additionally, located below the collar 34 is the handle portion 14, which may generally comprises a circular cross section, but may be varied as required for design considerations. The handle portion 14 merges into the working end portion 30 and the working end portion 30 is disposed to retain the steel holder 18. The scraper holder 18 is next disposed to retain the scraper blade device 20. The scraper blade device 20 terminates at its lower end in a chisel-like edge.

In order to properly retain the scraper blade device 20, the scraper holder 18 may have a series of attachment mechanisms 16 which are in mechanical communication with the steel holder 18 through drilled apertures 38 as seen in FIG. 3.

FIG. 3 illustrates a top plan view of the floor scraper mechanism 10. The drilled apertures 38 are shown. When wanting to attach a scraper blade, a user would align the scraper blade with the drilled apertures 38. Then, an attachment means like bolts are in communication with the drilled apertures 38 and the scraper blade device, securing the scraper blade device to the floor scraper mechanism 10.

FIG. 4a illustrates a right side view of one embodiment of the floor scraper mechanism 10, wherein a blade apparatus is not attached. FIG. 4b illustrates a rear view of one embodiment of the floor scraper mechanism, wherein a blade apparatus is not attached. FIG. 4c illustrates a rear perspective view of the steel holder 18 of one embodiment of the floor scraper mechanism, wherein a blade apparatus is not attached.

FIG. 5 illustrates a rear view of one embodiment of the floor scraper mechanism, illustrating the upper shank portion 12 and an extended handle portion 14.
