This invention relates to hand tools and, more particularly, to a multi-functional tool for assisting a user to install drywall in a building structure.
As anyone who performs a lot of physical work will attest, nothing beats having the proper tool for a job. The proper tool can save time, save money, produce a higher quality job, reduce damage to equipment, and provide for the increased safety of the worker. One (1) type of work common to new construction, remodeling, repair, general maintenance and the like is that of drywall work.
While a minimum of tools is needed for such work, they are utilized almost continuously. Perhaps three (3) of the most common are the putty knife, the hammer and the Phillips screwdriver. A worker must constantly flip back and forth between all of these tools to complete a task. However, such tools are not always handy, forcing the worker to stop what he or she is doing and look for them. Such lost time results in lost income for a contractor and aggravation for the casual user. Accordingly, there is a need for a means by which one (1) drywall tool can be afforded the functionality of multiple drywall tools.
In view of the foregoing disadvantages inherent in the prior art, it has been observed that there is need for a multi-functional tool for assisting a user to install drywall in a building structure.
The apparatus comprises a tool comprising an obliquely shaped body and an auxiliary implement which is removably coupled directly to the handle receiving aperture, the auxiliary implement being axially centered with the upper body portion and medially disposed between the fastener receiving end. The obliquely shaped body comprises an upper body portion, a lower body portion, a fastener receiving end disposed within a bottom side of the lower body portion, a hammering end disposed within a first side of the upper body portion and a handle receiving aperture disposed within the lower body portion. The hammering end is monolithically formed within the upper body portion. In a separate embodiment, the hammering end has an arcuate outer surface for smoothing protrusions.
The auxiliary implement may comprise a handle formed at a proximal end and a blade formed at a distal end. The blade may extend longitudinally from the distal end. The proximal end may be slidably interfitted within the handle receiving aperture. The proximal end may maintain a frictional interlocking relationship with the handle receiving aperture during operating conditions such that the auxiliary implement remains fixedly aligned along a longitudinal centerline of the body.
The lower body portion may be further provided with a first fastener aperture disposed adjacent to the handle receiving aperture and spaced therefrom, while the auxiliary implement further may include a second fastener aperture which is formed within the proximal end. The first fastener aperture and the second fastener aperture may be centrally aligned for removably receiving a locking member therethrough such that the auxiliary implement is prohibited from prematurely detaching away from the body.
The upper body portion may also comprise a slot which is disposed within a second side of the upper body portion opposite the hammering end. The slot may be configured to removably receive a fastener bit therein while the fastener bit may be received within the slot, while a distal end of the fastener bit remains outwardly exposed from the body for engaging a work surface.
The fastener bit may comprise one (1) fastener which is selected from a group of fasteners including, but not limited to: a Phillips head screwdriver, a flat head screwdriver, and a polygonal-shaped screwdriver. The slot may comprise a plurality of spring-loaded ball bearings which are housed within and are capable of partially traversing a travel path of the fastener. A plurality of engagement pins may directly abut against the ball bearings when the fastener is inserted into the slot.
The upper body portion may also have a cubby hole which is incorporated in a side wall of the upper body portion which is suitable for slidably engaging and storing the fastener bit during non-operating conditions. The auxiliary implement may comprise one (1) tool selected from a group of tools including, but not limited to: a putty knife, a trowel, and a scraper.
A method for employing the multi-functional tool during drywall installation comprises the steps as follows: first, obtaining a body having a hammering end, a handle receiving end and a fastener bit receiving end; second, inserting a proximal end of an applicator handle into a handle receiving aperture such that the handle is frictionally retained therein; third, attaching an applicator handle to a body wherein the handle linearly extends away from the body; fourth, inserting a fastener bit in a slot to matingly engaging therewith; and last, grasping an exposed end of the handle and selectively utilizing the multi-functional tool as a hammering device, a fastener driving device, and an applicator respectively.
The method may further comprise the steps as follows: first, inserting a locking member into a securing aperture and a hanging aperture of the handle; and, last, securing a bolt within the securing aperture by applying a nut at an opposing end of the bolt. The method may further comprise the additional step of removing a fastener bit from the slot by transversely pulling the fastener bit away from the body.
The method may last comprise the steps as follows: first, removing the bolt from the hanging aperture of the handle and the securing aperture of the body; second, removing a proximal end of the handle from the handle receiving aperture of the body portion by pulling transversely therefrom; and last, storing the handle away from the body for later utilization.

Common screwdriver fastener bits 50 comprise a hexagonally-shaped the chuck 55 or the like to be inserted therein the slot 60 such that the head portion 56 of the fastener bit 50 is extending beyond the upper end of the screwdriver bit receiving end 40. On the opposing end of the screwdriver bit receiving end 40 is the hammering end 45 designed to be utilized for driving in recessed nails, removing obstructions, and the like. There hence, the apparatus 10 eliminates the need to replace tools for alternate screwdrivers and wall finishing functions.
The apparatus 10 provides more functionalities within a single tool in which may be utilized with a single hand thereby utilizing the opposing hand to help maintain balance, to hold other work-related items such as a pan of putty or other materials, or the like. For instance, a worker may be utilizing the putty knife 20 to spread drywall putty on drywall and may notice a nail on the wall that require pounding to provide a smoother surface. While still holding the pan of putty or maintaining balance with one (1) hand, the worker can then grasp the exposed handle 25 of the putty knife 20 with the opposing hand and swing the apparatus to provide a levering action to utilize the hammering end 45 to drive in the nails.
Further, the worker may also notice that whilst applying putty or mud utilizing the putty knife 20 that a screw is protruding outwardly and requires tightening. While still holding the pan of putty or maintaining balance with one (1) hand, the worker can then grasp the exposed handle 25 once again and insert the fastener bit 50 into the head of the screw and rotate to tighten said screw providing that the desired interchangeable screwdriver fastener bit 50 is already removably engaged therein the slot 60 positioned at the screwdriver bit receiving end 40.
Another example of an instance may include a worker may occasionally need to remove a drywall screw from a sheet of drywall. The worker may utilize the screwdriver fastener bit 50 removably engaged therewithin the slot 60 as previously indicated, which results in a raised shoulder about the periphery of the hole from which the drywall screw is removed. The worker may turn the apparatus 10 over and utilize the hammering end to pound the raised shoulder to form a dimple within the drywall sheet to which drywall putty may be applied by turning the apparatus 10 over and utilizing the blade 28 of the putty knife 20. As previously mentioned, these are just examples of how useful the apparatus 10 is in instances a common worker may experience while working on the job.
