Description
DRYWALL HAWK
Field of the invention The present invention relates to a drywall hawk. More particularly, the present invention relates to a drywall hawk to be used with mortar, plaster, and the like, in order to carry out various masonry, plastering, and surfacing applications.
Background of the invention Drywall hawks are very well known in the art. They generally consist of a substantially flat metallic plate having top and bottom surfaces and a wooden handle projecting perpendicularly from the bottom surface of the metallic plate.
Mortar, plaster and the like are generally supported onto the top surface of the hawk for carrying out various masonry, plastering, and surfacing applications, with drywall and with other types of surfaces. The hawk may also be used for straightening out and leveling these various working materials onto the above-mentioned types of surfaces.
A major problem associated with the above-mentioned type of instrument is that a user will often have to manipulate it in various ways, namely will often have to use his fingers to rotate the handle in order to rotate the plate, which is rigidly connected to the handle, so as to be able to properly carry out the necessary work involved. The conventional design of the drywall hawk, in addition to the choice of materials used for its various components, namely the plate and handle thereof, make handling and holding of the hawk fairly difficult and strenuous, especially when employing the hawk during a long period of time and when carrying out various handling maneuvers. For example, the rotation of the handle with the fingers of the same hand which holds the hawk is a common maneuver that often has to be repeated several times during normal masonry, plastering, and surfacing applications. This often results in aches and pains in the fingers, as well as the formation of calluses thereon due to the rubbing of the fingers with the various components of the drywall hawk moving thereagainst.
Therefore, it would be very useful to provide an improved hawk enabling a more ergonomic hand!ing thereof than what is possible with the hawks known in the prior art.
Hence, in light of the aforementioned, there is a need for an improved hawk which, by virtue of its design and components, would be able to overcome some of the above-mentioned problems and concerns.
Summary of the invention The object of the present invention is to provide a hawk which satisfies some of the above-mentioned needs and which is thus an improvement over other related hawks known in the prior art.
In accordance with the present invention, the above object is achieved by a hawk for use with a substantially malleable working material, the hawk comprising:
a plate having top and bottom surfaces;
a handle projecting from the bottom surface of the plate; and swiveling means operatively positioned between the bottom surface of the plate and an upper portion of the handle for enabling the bottom surface of the plate to be rotatably moveable about the swiveling means, the swiveling means comprising at least one ring mounted about the upper portion of the handle, the at least one ring having top and bottom surfaces, the top surface of the at least one ring being slidably moveable against the bottom surface of the plate for allowing a rotation of the plate about said at least one ring.
Preferably, the at least one ring may be either a swivel ring, a cushioning ring or a combination of both.
