The present invention relates to a glass etching and breaking apparatus. Specifically, the glass etching and breaking apparatus of the present invention comprises a glass cutting tool and a flexible bridging element for inducing a score line into a pane of glass and aiding in breaking the pane of glass along the score line. The cutting tool is removable and storable within the body of the glass cutting apparatus. A magnet is provided for holding the cutting tool in place and for holding metal or magnetic objects. Methods of using the same are further provided.
Glass cutting has been around for centuries, if not millennia. Tools have been developed to aid in allowing users to provide specific and desired score lines in panes of glass, and to break the panes of glass precisely along the score line. For example, to place a score line into a pane of annealed glass, a cutting tool is typically used. The cutting tool generally comprises a small cutting wheel made of hardened steel or tungsten carbide that is generally about 4 to about 6 mm in diameter with a V-shaped profile called a “hone angle.” The cutter is then rolled firmly over the glass, producing a “score line” or “fissure,” weakening the glass along this line. Tools, of course, have been developed to aid users in providing score lines in panes of annealed glass.
For example, a glass cutting apparatus called “Studio Pro™” by Diamond Tech and similar apparatuses comprise a hollow base with a grip on one side that is Tillable with oil (to aid as a lubricant in the cutting process), and a cutting tool extending form a corner thereof. The cutting tool may be used to etch a score line into a pane of glass, and the oil may drip from the base to lubricate the glass during the score line etching process. However, this apparatus tends to leak oil, is difficult to manage, and is unwieldy and difficult to hold and store due to the cutting tool that extends from the body at an oblique angle.
A need, therefore, exists for an improved glass etching and breaking apparatus. Specifically, a need exists for a glass etching and breaking apparatus having an extendible glass cutting tool that can be removed and changed. More specifically, a need exists for a glass etching and breaking apparatus having a storage slot or chamber within the body of the glass cutting apparatus for holding and storing the glass cutting tool so the same is not lost.
Breaking the glass along the score line is often the most difficult part of the process, in that if incorrectly done, or if the score line is not sufficient, the glass can break in locations that are unintended, leading to waste of the glass, and in more serious circumstances, injury to the user. Tools have been developed to aid in breaking glass along score lines as intended by users.
For example, a tool called the “Safety Break” from Morton Glass Works comprises a pair of parallel flexible bridging members attached together on each end. The bridging members can flex toward each other when depressed on one or the other side thereof. Thus, a pane of glass having a score line etched therein that is placed adjacent one of the flexible bridging members and pressed toward the bridging member causes the pane of glass and the bridging member to flex, breaking the pane of glass along the score line. A user can press upon the glass using his or her fingers, or may use another tool, such as a round button or the like. This tool can be effective at breaking a score line etched in a pane of glass where desired, but it is limited because it does not include a cutting tool as part of the apparatus, requiring a separate cutting tool to etch the score line.
A need, therefore, exists for an improved glass etching and breaking apparatus that provides both etching and aids in breaking a pane of glass. Specifically, a need exists for an improved glass etching and breaking apparatus comprising flexible members that can be used to break etched glass along a score line, while also including a cutting tool extending therefrom. More specifically, a need exists for an improved glass etching and breaking apparatus comprising a cutting tool that is removable and storable within the body of the flexible members, thereby holding and storing the cutting tool so the same is not lost.

Additional features and advantages of the present invention are described in, and will be apparent from, the detailed description of the presently preferred embodiments and from the drawings.
The drawing figures depict one or more implementations in accord with the present concepts, by way of example only, not by way of limitations. In the figures, like reference numerals refer to the same or similar elements.
The present invention relates to a glass etching and breaking apparatus. Specifically, the glass etching and breaking apparatus of the present invention comprises a glass cutting tool and a flexible bridging element for inducing a score line into a pane of glass and aiding in breaking the pane of glass along the score line. The cutting tool is removable and storable within the body of the glass cutting apparatus. A magnet is provided for holding the cutting tool in place and for holding metal or magnetic objects. Methods of using the same are further provided.
Now referring to the figures, wherein like numerals refer to like parts,
The first bridging leg 14 and the second bridging leg 16 each have a degree of flex, such that pressing down on one or both of the first and second bridging legs 14, 16 causes them to deflect towards each other. When released, each of the first and second bridging legs 14, 16 retain their original position. Thus, each of the first and second bridging legs 14, 16 acts as a leaf spring, where deformation of each may be caused by pressing on each, but each springs back to its original position when the pressure is released.
Extending from the second end 22, preferably at an oblique angle to the sides of the base 12 may be a cutting tool 24, which may extend from a cavity 26. In one embodiment, the cutting tool 24 may be permanently sealed in the cavity 26. In a preferred embodiment, the cutting tool 24 may be removable from the cavity 26, as described in more detail below. A cutting wheel 28 may be disposed on an end of the cutting tool 24 for etching a score line in a pane of annealed glass, as illustrated in
A magnet 29 may be positioned within the second end 22 of the apparatus 10, which may have multiple functionalities. In an embodiment, the magnet 29 may hold the cutting tool 24 within the cavity 26 so that the same does not readily fall out of the cavity 26 when in use. In addition, or alternatively, the magnet 29 may be utilized by a user to magnetically attract magnetic or metallic items, such as metal item 40 (showing a metal ball that may be used in the etching and breaking of the glass, as apparent to one of ordinary skill in the art) as shown in
As shown in
Referring now to
Alternatively, the cutting tool 24 may be turned around and disposed within the cavity 26 for storage of the same out of the way, as illustrated in
Guide ridges 34, 36 may extend within the cavity 26 on inside surfaces of the legs 14, 16, respectively, to guide the cutting tool 24 as it is fully inserted therein. Therefore, the cutting tool 24 may be placed therein and stored within the cavity 26 when not in use so the same is not lost. Moreover, the cutting tool 24 may be removed and placed within the cavity 26 when the apparatus 10 is used in a manner in which the cutting tool 24 would get in the way. For example, as illustrated in
It should be noted that various changes and modifications to the presently preferred embodiments described herein will be apparent to those skilled in the art. Such changes and modifications may be made without departing from the spirit and scope of the present invention and without diminishing its attendant advantages. Further, references throughout the specification to “the invention” are nonlimiting, and it should be noted that claim limitations presented herein are not meant to describe the invention as a whole. Moreover, the invention illustratively disclosed herein suitably may be practiced in the absence of any element which is not specifically disclosed herein.
