The present invention relates to an eyewear frame assembly that is impact resistant. More particularly, the present invention relates to an impact resistant eyewear frame assembly having a split frame for easily inserting and removing a lens. Still more particularly, the present invention relates to an impact resistant split frame having projections adapted to be received by a sleeve to secure a lens within the frame, as well as a threaded fastener and a threaded bushing received inside the sleeve to form a reinforcement assembly for two portions on the split frame.
Eyewear frame assemblies often need to be impact resistant, such as when worn for sporting activities. ASTM F803 is a stringent standard governing impact resistance requirements for eyewear worn during sporting activities. Polycarbonate is the material of choice for eyewear frames meeting the ASTM F803 requirements. That is used for non Rx-able frames known as Plano frames, no prescription lenses. For prescription eyewear, there needs to be a way to insert the lenses and still maintain the impact strength of the material. Heating of the eyerim of a frame is the known norm for the insertion of lenses into plastic sport frames. Heating of most eyewear frame materials, such as polycarbonate, to insert lenses in the eyewear frames destroys the impact resistance strength of the frames. Some materials are extremely resistant to heat, thereby preventing heating as an option for inserting lenses in the eyewear frames. Still other materials require an excessively thick eyewear frame to meet the impact resistance requirements, so that the resulting eyewear frames are aesthetically undesirable, bulky and awkward for wearers. A need exists for eyewear frames that allow for insertion of lenses without affecting the impact resistance of the eyewear frames and still provide aesthetically pleasing and efficient eyewear frames.
Eyewear frames in which lenses can be easily inserted and still withstand impact are greatly desired by wearers. Heating frames to insert lenses and still maintain impact usually requires the frame to be bulky. Eyewear frames exist that allow the wearer to remove and insert lenses. However, most existing eyewear frames do not provide the impact resistance required by ASTM F803. Wearing such eyewear frames during a sporting activity could result in serious injury to wearers if the frames and lenses are not able to sustain impacts. A need exists for eyewear frames that allow for easy insertion and removal of lenses, while still meeting the impact resistance requirements for use during sporting activities.
Thus, there is a continuing need to provide improved eyewear frame assemblies.
Accordingly, it is a primary objective of the present invention to provide an improved eyewear frame assembly that is impact resistant and reinforced.
Another object of the present invention is to provide an aesthetically appealing and efficient eyewear frame assembly having a minimal amount of material that meets the impact resistance requirements needed for safe use during sporting activities.
Another object of the present invention is to provide an eyewear frame assembly that allows for easy insertion and removal of lenses while still providing the impact resistance required for use during sporting activities.
The foregoing objects are basically attained by providing an eyewear frame assembly having an aperture for receiving a lens, the frame having a split to expand upper and lower portions of the frame to insert or remove the lens from the aperture, first and second projections extending outwardly from the upper and lower frame portions, respectively, the first and second projections having first and second tapered portions, respectively, a sleeve receiving the first and second projections, the sleeve having first and second inwardly extending tapered tabs adapted to receive the first and second tapered portions to secure the first and second projections within the sleeve, the upper and lower portions of the frame being prevented from expanding when the first and second projections are received within the sleeve, first and second openings in the sleeve for providing access to depress the first and second projections to remove the first and second projections from the sleeve; a bushing coupled to one of the upper and lower portions and having a threaded passageway therein; and a fastener coupled to the other of the upper and lower portions and having a threaded section threadedly engaged with the threaded passageway to prevent the upper and lower portions from moving away from one another, the bushing and the fastener being located inside the sleeve.
Other objects, advantages and salient features of the invention will become apparent from the following detailed description, which, taken in conjunction with the annexed drawings, discloses a preferred embodiment of the invention.
Referring now to the drawings that form a part of the original disclosure:
An eyewear frame assembly 11 according to the present invention is shown in
While an eyewear frame assembly 11 having first and second apertures is hereinafter described, the present invention is also applicable to an eyewear frame assembly having a single aperture for receiving a single lens.
The frame 21, as shown in
A second split 24 in the frame 21 separates the frame into second upper and second lower portions 26 and 28, respectively, as shown in
A first projection 31 extends outwardly on the first upper portion 25 of the frame 21, as shown in
A third projection 35 extends outwardly on the second upper portion 26 of the frame 21, as shown in
A first sleeve 41 receives the first and second projections 31 and 33 through an opening 42 in a first end 44 of the sleeve, as shown in
A second sleeve 51 receives the third and fourth projections 35 and 37 through an opening 52 in a first end 54 of the sleeve, as shown in
First temple arm 91 has a first passageway 92 therethrough that receives the first fastener 75 to pivotally connect the first temple arm to the first sleeve 41, as shown in
Second temple arm 95 has a second passageway 96 therethrough that receives the second fastener 85 to pivotally connect the second temple arm to the second sleeve 51, as shown in
Preferably, the frame 21 and first and second sleeves 41 and 51 are made of plastic. More preferably, the frame 21 and first and second sleeves 41 and 51 are made of nylon or other similar strength material.
Assembly and Disassembly of First Embodiment of
A fully assembled eyewear frame assembly 11 is shown in
The first upper and lower portions of the frame 25 and 27 are pulled apart at the first split 23 so that a first lens 13 may be inserted in the first groove 16. Once the lens is inserted, the resiliency of the frame pulls the first upper and lower portions 25 and 27 back together. First and second projections 31 and 33 are then inserted into the opening 42 at the first end 44 of the first sleeve 41, as shown in
As shown in
First fastener 75 is inserted through first fastener hole 73 in the outer surface 48 of the first sleeve 41 and through the aligned passageway 92 in the first temple arm, as shown in
To remove the first and second projections 31 and 33 from the first sleeve 41, the first pin 71 is removed from the third opening 72 in the first sleeve. The first and second projections 31 and 33 are then depressed through first and second openings 47 and 49 in the outer surface 46 of the first sleeve 41, such as with pliers. By depressing the first and second projections, the first and second projections may be disengaged from the first and second inwardly extending tapered tabs 43 and 45 and pulled out through the first opening 42 in the first sleeve. The first and second upper portions 25 and 27 may then be pulled apart at the first split 23 to change the first lens 13 as desired.
The same process applies to the assembly and disassembly of the third and fourth projections 35 and 37 with the second sleeve 51 and second temple arm 99.
Second Embodiment of
A second embodiment of the present invention is shown in
More specifically, as seen in
