## Background
RELATED APPLICATIONS
The present invention is a Continuation-in-part of and claims the benefit of U.S. application Ser. No. 14/072,271, filed Nov. 5, 2013, the entire disclosures of which are incorporated herein by reference.


FIELD OF THE INVENTION
The present invention relates to a safety eyeglass case and accompanying mounting brackets to secure the case to a power tool and thereby stow safety glasses in a convenient manner for ready and immediate access.
BACKGROUND OF THE INVENTION
The use of safety glasses or protective eyewear has increased in both work and industrial environments. They are no longer only seen at construction sites and industrial establishments throughout the country, but at homes and commercial environments as well. Their use has resulted in reduced eye injuries, and an overall improvement in safety. One (1) area in which eyewear is typically used, or should be used, is when operating a string style trimmer when performing landscaping, or yard work. The possibility of grass clippings, stones, twigs, and the like, being thrown up into the operator's eyes is very real. One (1) of the most frequently heard excuses as to why an operator will not wear safety glasses is that they cannot be found, they are lost, or they take too long to go and get them. Then, when they are found, they are broken, scratched, or otherwise damaged. Accordingly, there exists a need for a means by which safety glasses can be provided in more ready access to be more easily and properly utilized when operating a string style trimmer or similar power tool.
SUMMARY OF THE INVENTION
The case and mounting bracket of the present invention is a safety glasses storage case designed to mount to the cylindrical shaft of a string-style trimmer or similar power tool. Upon initial observation of a string-style weed trimmer equipped with the present invention, nothing appears readily different. However, after closer inspection, it can be seen that there is a safety eyeglass case mounted to the shaft of the weed trimmer near the shaft handle grip. The case has a hinged lid that snap locks closed and will hold one (1) pair of safety eyeglasses complete with side shields. There also exists a means to secure a set of safety earplugs within the case as well. The case is capable of being attached to the shaft of the trimmer using the attached mounting brackets that are sized to fit a variety of circular power tool shafts, but may also be adapted to fit other shaft shapes as well. These features ensure that safety glasses will always be readily available when beginning operation of the power tool, and provides a handy place for storage where they will not get damaged or scratched.
In a preferred embodiment of the invention, the case has a bottom wall that has integral hemispherical-shaped base brackets, each capable of mating with a mounting bracket segment of a mounting bracket assembly, possessing a similar hemispherical shape. The arcuate mating sides of both the base brackets and mounting bracket segments are capable of conforming to an outer circumference of a cylindrical shaft of a work tool. Fasteners mate an aligned individual base bracket and mounting bracket segment pair.
In another embodiment of the invention, at least one (1) cylindrical receptacle is affixed within the interior of the case. Each holder is capable of retaining a conventional foam safety earplug therewithin.
In yet another embodiment of the invention, a first mounting bracket assembly differs from a second mounting bracket assembly in that a first mounting bracket segment is longer than the second mounting bracket segment. Such an additional length accommodates a bracket aperture, capable of either accepting another mounting means to mount the case to a different support structure, or for enabling routing of a hasp of a lock therethrough to prevent unauthorized removal of the case from the support structure.
Thus, when the present invention meets the need for a way to keep and store protective safety eyeglasses and safety earplugs when not using the tool, but also keeps them at ready access in an immediate location to encourage their consistent use, which results in better safety and protection for the operator.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
The best mode for carrying out the invention is presented in terms of its preferred embodiment, herein depicted within FIGS. 1 through 8. However, the invention is not limited to the described embodiment and a person skilled in the art will appreciate that many other embodiments of the invention are possible without deviating from the basic concept of the invention, and that any such work around will also fall under scope of this invention. It is envisioned that other styles and configurations of the present invention can be easily incorporated into the teachings of the present invention, and only one particular configuration shall be shown and described for purposes of clarity and disclosure and not by way of limitation of scope.
The terms “a” and “an” herein do not denote a limitation of quantity, but rather denote the presence of at least one of the referenced items.
The present invention describes a safety eyeglass case 20 with mounting bracket assemblies 10a, 10b (herein referred to as the “case”), which provides a means to retain a pair of safety eyeglasses 100 within the interior 54 of the case 20 that is mounted to the shaft 105 of a support structure such as a work tool so that said safety eyeglasses 100 are available for use by the tool user. There is also means within the interior 54 of the case 20 for the additional retention of a pair of collapsible foam safety earplugs 101.
Referring now to FIG. 1, an isometric view of the case 20 according to the preferred embodiment of the present invention, is disclosed. The case 20 also includes a lid 40 generally coextensive with an upper perimeter edge of the case side wall 26. A preferred embodiment of the case 20 and lid 40 is in a hemispherical configuration to generally match the profile of convention pair of safety eyeglasses 100 also having a general hemispherical shape. This preferred embodiment is efficient in that it minimizes the amount of wasted space in order to limit instances where the case 20, as attached the shaft 105 of a work tool, may be snagged or otherwise impeded normal use of the work tool.
The lid 40 and case 20 are constructed preferably of a rigid thermoplastic, or other such material, as two (2) individual parts in an injection molding process. The case 20 includes an arcuate case sidewall 26, a planar case rear wall 23, and a planar case bottom wall 24 to form an interior 54 of sufficient volume for the storage of a pair of safety eyeglasses 100. The case sidewall 26 conjoins along all abutting edges of the case rear wall 23 and case bottom wall 24. At least one (1), and preferably a pair, of earplug holders 80 are affixed to the inner surface of the case bottom wall 24 and extend upward into the interior 54. The holders 80 are cylindrical receptacles and are preferably located along a common centerline of the case bottom wall 24. The preferred location of the holders 80 enable a pair of safety eyeglasses 100 can be placed in the case and not be interfered with by the holders 80. The cylindrical receptacle shape of each holder 80 enables a convention foam safety earplug 80 to be inserted therein, wherein the deforming aspect of the foam safety earplugs 101 enable a frictional secure fit therewithin.
The case bottom wall 24 incorporates two (2) bracket base 32 portions in a unitary construction. The bracket base portions 32 are aligned along a common centerline of the case bottom wall 24 and are capable of mating to one (1) of the first and second mounting bracket assemblies 10a, 10b via a fastener 71 removably placed within a channel 36 passing through the thickness of the bracket base 32. More than one (1) channel 36 may exist. As best illustrated in FIG. 4, each bracket base 32 is provided with a base passageway 34 which is a hemispherical void in said bracket base 32 capable of conforming to the cylindrical shaft 105 of the work tool. In some embodiments the case bottom wall 24 may have contours other than a strictly planar configuration without limiting the scope of the case 20.
The lid 40 is much thinner than the case 20, yet generally has a coextensive shape thereof. The lid 40 includes an arcuate lid sidewall 42, a planar lid rear wall 43, and a planar lid upper wall 44. The lid sidewall 42 conjoins along all abutting edges of the lid rear wall 43 and lid upper wall 44.
Referring now to FIGS. 2 and 3, isometric views of the case 20 in an open configuration both empty and filled with commonly used safety equipment, such as safety eyeglasses 100 and safety earplugs 101, is disclosed. The lid rear wall 43 and the case rear wall 23 are attached to opposite leaves of a hinge 52 preferably by means of rivets, or other such fasteners, in order to enable the lid 40 to be hingedly attached to the case 20. The lid 40, when fully closed against the case 20, fully covers the interior 54 of the case 20. The hinge 52 would preferably incorporate a spring, or spring like device to hold the case 20 in a closed configuration.
As best illustrated in FIG. 4, the lower bracket segments 62a, 62b of the bracket assemblies 10a, 10b are each comprised preferably of a rigid thermoplastic, or other such material and formed with a bracket passageway 64 similar to the base passageway 34 in the bracket base 32 pieces previously discussed. When each bracket base 32 is conjoined with a corresponding lower bracket 62a, 62b the base passageway 34 and the bracket passageway 64 form a joined passageway permitting entrance of a cylindrical shaft 105 of a work tool. Disposed in the lower bracket segments 62a, 62b is at least one (1) bracket aperture 66, which, when aligned with an individual channel 36 of the base brackets 32, fasteners 71 can then clamp the case 20 to a shaft 105 of a work tool.
A preferred embodiment includes a first mounting bracket assembly 10a and a second mounting bracket assembly 102. The first mounting bracket assembly 10a differs from the second mounting bracket assembly 109b in that the first lower bracket segment 62a has a greater length than the second lower bracket segment 62b in order to accommodate a bracket aperture 63. The bracket aperture 63 is a passthrough channel that is capable of enabling the case 20, when attached to the first mounting means assembly 10a and via an external mounting means, to another location instead of a cylindrical shaft 105. The bracket aperture 63 also enables the hasp of a lock to be routed through to provide a secure locking means for the case 20 to the cylindrical shaft 105.
FIGS. 5 through 8 illustrate various views of the safety eyeglass case 20 with the mounting bracket assemblies 10a, 10b installed thereon, in accordance with the preferred embodiment of the present invention.
The preferred embodiment of the present invention can be utilized by the enabled user in a simple and straightforward manner with little or no training. After initial purchase or acquisition of the case 20, it would be installed as indicated in FIG. 1. The method of installing and utilizing the case 20 may be achieved by performing the following steps: installing the case 20 onto a shaft 105 of a work tool by fitting the shaft 105 into the base passageways 34 of each bracket base 32; fitting the bracket passageway 64 of the lower bracket segments 62a, 62b onto the shaft 105 opposite from the bracket bases 32; aligning the bracket apertures 66 with the channels 36; installing the required number of fasteners 71; repeating the procedure to complete the installation of the remaining lower bracket segments 62; and inserting a user-supplied pair of safety eyeglasses 100 into the case 20. Also, a pair of safety earplugs 101 can be secured within the holder 80 located in the interior 54 of the case 20 as desired.
Alternately, the bracket aperture 63 can be used to mount the case 20 to a different location than the shaft 105 of a work tool, or be utilized to rout a hasp of a locking device in order to prevent unauthorized removal of the case 20 from the shaft 105 of the work tool.
