Description

BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWINGS

[0021] The invention will be better understood and objects other than those set forth above will become apparent when consideration is given to the following detailed description thereof. Such description makes reference to the annexed drawings wherein:

[0022] FIG. 1 is a perspective view of the cutting device of the present invention.

DETAILED DESCRIPTION OF THE INVENTION

[0023] In the following detailed description, reference is made to the accompanying drawings which form a part hereof, and in which is shown by way of illustration specific embodiments in which the invention may be practiced. These embodiments are described in sufficient detail to enable those skilled in the art to practice the invention, and it is to be understood that the embodiments may be combined, or that other embodiments may be utilized and that structural and logical changes may be made without departing from the spirit and scope of the present invention. The following detailed description is, therefore, not to be taken in a limiting sense, and the scope of the present invention is defined by the appended claims and their equivalents.

[0024] In construction industries Drywall is a product commonly used to finish building interiors. It is also known as plasterboard, wallboard, and gypsum board and also known as a panel made of gypsum plaster pressed between two thick sheets of paper. It is used to make interior walls and ceilings. Drywall is made of a core of gypsum that is sandwiched between two layers of heavy paper. Without the paper, the gypsum will crack and break apart easily. Gypsum is a soft white or gray rock that generates dust when it is cut. Tools that do not generate dust and that are designed for cutting the paper are best. To cut a straight line on the drywall, a short metal blade has been developed for electric-powered reciprocating tools that are designed specifically to cut holes into existing drywall.

[0025] The present invention comprises a drywall cutting device, for marking and making cuts parallel or perpendicular to a reference edge of a drywall (gypsum wallboard) sheet. FIG. 1 of the present disclosure illustrates the use of the present device. The device essentially comprises a pivot pin 1, a head portion 2, a screw 3 for cutting circles, a decker 4, a tool arm 5, tool guide locking pin, a guide 7 for sliding along the arm, a stationary back 8, a clamping screw 9 and center pivot point 10 respectively.

[0026] The invention is used in its preferred embodiment by attaching a marking device to the drywall surface. The user then holds the drywall cutting device in one hand. After measuring the desired length, the tool arm 05 is moved such that the decker slides along with the drywall surface for straight cut. The adjustable tool clamp 08 holds all cutting and marking tools. The adjustable tool clamp 08 allows for easy adjustment for all the measurements ranges from 0-2 feet. The device is made from light weighted material like aluminum.

[0027] Use of the circle cutting device is as follows: The user selects the point on a sheet of drywall that the center point of a circular opening in the sheet. The user embeds the fixing guide locking pin 06 in the chosen center point by pressing on the pivot point 10. Then by choosing the appropriate groove for the size chosen hole, and inserting the drywall cutting device through the selected groove into the sheet of drywall. The user then pushes the tool arm 05, utilizing the end removal point 03, in a circle until completing a 360° arc, thus cutting or scoring a circular opening in the drywall.

[0028] It is to be understood that the above description is intended to be illustrative, and not restrictive. For example, the above-discussed embodiments may be used in combination with each other. Many other embodiments will be apparent to those of skill in the art upon reviewing the above description.

[0029] The benefits and advantages which may be provided by the present invention have been described above with regard to specific embodiments. These benefits and advantages, and any elements or limitations that may cause them to occur or to become more pronounced are not to be construed as critical, required, or essential features of any or all of the embodiments.

[0030] While the present invention has been described with reference to particular embodiments, it should be understood that the embodiments are illustrative and that the scope of the invention is not limited to these embodiments. Many variations, modifications, additions and improvements to the embodiments described above are possible. It is contemplated that these variations, modifications, additions and improvements fall within the scope of the invention.
