I. Field of the Invention
The present invention relates generally to the field of tools, and more particularly to a multi-function tool that provides functionality common to painters' needs.
II. Description of the Related Art.
Often times, workers, such as painters, require supporting tools to perform their tasks. In addition to the basic equipment required by a painter, such as a paint brush and paint roller, a painter may require various additional pieces of equipment to perform necessary functions, such as scraping, various cutting tasks, spreading, cleaning rollers, scraping caulk, removing lids from paint cans, hammering nails, driving screws, and the like. It is appreciated that each of these tasks requires separate tools, the carrying and organization of which can burden the painter.
Thus, it is readily apparent that there is a need for a multi-function tool apparatus and system that allows a painter, or other worker, to conveniently perform many tasks or functions using a single tool or tool system.
Briefly described in a preferred embodiment, the present invention overcomes the above-mentioned disadvantages and meets the recognized need for such an invention by providing a multi-function tool apparatus and system comprising a handle and a utility blade operable to accommodate a plurality of functions, thus, reducing a number of ancillary tools required by a painter, or other worker.
According to its major aspects and broadly stated, the present invention, in its preferred form, is a multi-function tool apparatus and system comprising a handle having a butt end that includes a screwdriver in threaded engagement with the handle. The screwdriver may be removed to expose a shaft and a plurality of screwdriver bits of varying configuration. The butt end further preferably includes a bolt in threaded engagement therewith. The bolt may be removed to attach an elongated pole to allow performance of tasks or functions at remote areas. The structure of the utility blade preferably accommodates a plurality of functions including, but not limited to, scraping, putty spreading, caulk scraping, can opening, roller wiping, cutting; turning threaded fasteners; nail pulling, nail driving, and the like.
The system may further include one or more replaceable blade or point tips for replacement of a cutting blade or scraping point of the multi-function tool, which cutting blade or scraping point may be prone to wear, and may become worn to an extent that it is no longer useful well before other features of the tool have become worn or damaged through ordinary use. The replaceable blade(s) and/or point(s) are preferably retained in engagement with the multi-function tool via a removable sleeve that captures a replaceable blade or point and secures it to the utility blade of the multi-function tool. Disengagement of the sleeve from the utility blade preferably allows a worn blade or point to be replaced with a new blade or point.
In general, according to one aspect, the invention features a tool apparatus including a handle, a utility blade disposed on one end of the handle, and a butt end disposed on another end of the handle. The utility blade may include a first utility edge disposed on a first side portion thereof, a second utility edge on a second side portion thereof, and a third utility edge disposed between the first and second utility edges, generally defining a forward edge of the utility blade. Each utility edge may include one or more structures for performing associated tasks, such as a circular arc segment section for scraping a paint roller, a paint can opening level, a polygonal cutout for engaging a bolt head, a straight sharp cutting, scraping, and/or spreading edge, a curved sharp cutting and/or scraping edge, a cutting and/or scraping point and/or blade, or the like. Additionally, the utility blade may include one or more utility feature disposed on or through a broad surface of the blade, such as an aperture adapted to pull nails, or the like.
The handle includes a central handle portion, a butt portion in threaded engagement with the central handle portion and a bolt end in threaded engagement with the butt portion. The butt portion may include a sub-tool inverted to face inwards of a hollow interior of the handle. The inverted sub-tool is preferably a screwdriver removably attached to the handle via threading. When the bolt end is engaged with the butt portion, the bolt may be for hammering, such as to drive nails, or the like. The screwdriver may include a plurality of removable and interchangeable driver bits whereby a plurality of different fasteners of differing types may be rotated by the screwdriver. The bits are preferably housed in receiving sockets formed in the screwdriver for convenience and to prevent loss thereof. When the bold is removed from the butt portion, a rod or other member may be engaged with the butt portion, such as in order to reach remote areas for scraping, or the like.
In another aspect, the invention features method for performing painter's functions including providing a tool having a handle with a multifunctional blade having a first edge with a concave aperture, a second edge with a concave aperture and a hex profiled aperture, a third straight edge disposed between the first and second edges and having a first protrusion adjacent the first edge and a second protrusion adjacent the second edge, and a through-hole disposed on the multifunctional blade. The method further includes the steps of inserting a paint roller within the concave aperture on the first edge and running the paint roller along an edge of the concave aperture to clean the paint roller, spreading putty with the straight edge, scraping a surface with the straight edge, scraping caulk with the second protrusion, removing a lid from a paint can with the first protrusion, and/or removing a nail with the through-hole. The method may further include the steps of hammering an object with a bolt engaged with butt portion of the handle, removing the butt portion of the handle and rotating a fastener with a screwdriver of the butt portion, and/or removing a bolt from engagement with the butt portion and engaging an extension pole with the butt portion. The method may further include the steps of engaging a removable point or blade with a protrusion of the utility blade and securing the removable point or blade to the utility blade via a covering sleeve.
Accordingly, one feature and advantage of the present invention is its ability to provide a single tool apparatus capable of performing a plurality of tasks or functions associated with painting or other work, whereby the number of tools required by a painter or other workman may be reduced.
Another feature and advantage of the present invention is its ability to provide a removable screwdriver operable with a handle carrying a utility blade, whereby the screwdriver and a plurality of bits associated therewith may be stored and protected when not in use and may be conveniently carried by the handle and utility blade when not in use.
Another feature and advantage of the present invention is its ability to provide replaceable cutting blades and/or points, whereby replacement of the entire tool due to premature wear and/or damage to one portion thereof may be avoided.
