Abstract
An energy dispersion mechanism can be integrated into the eyewear design to incorporate a more resilient lens holding structure that can disperse the energy received during an impact and retain the lens in place. The energy dispersion mechanism comprises an impact dispersing material seated within a groove of a first frame portion, the impact dispersing material extending beyond the first frame portion to form a nose bridge which joins the first frame portion to a second frame portion; and the impact dispersing material is seated within a groove of a second frame portion. The impact dispersing material may be overmoulded on the eyewear to allow efficient manufacturing.
Claims21
An energy dispersion mechanism for eyewear comprising, in at least one frame portion for retaining a lens within a lens retaining groove:
- a groove formed in and extending at least partially along the frame portion that surrounds the lens such that part of the frame portion is interposed between the lens retaining groove and the groove;
- and
- an impact dispersing material positioned and extending within the groove such that the impact dispersing material does not contact with and is spaced apart from the lens and has the frame portion interposed therebetween.
Eyewear having an energy dispersion mechanism, comprising:
- a first frame portion surrounding and retaining a first lens within a first lens retaining groove;
- a second frame portion surrounding and retaining a second lens within a second lens retaining groove;
- first and second arms extending from the first and second frame portions respectively;
- and
- a bridge portion connecting the first frame portion to the second frame portion;
- wherein the energy dispersion mechanism comprises, in at least one of the frame portions:
- a groove formed in and extending at least partially along that frame portion that surrounds the respective lens such that part of that frame portion is interposed between the respective lens retaining groove and the groove;
- and
- an impact dispersing material positioned and extending within the groove such that the impact dispersing material does not contact with and is spaced apart from the respective lens and has the respective frame portion interposed therebetween.
A method of providing an energy dispersion mechanism to eyewear, comprising:
- forming a groove in and extending at least partially along at least one frame portion of the eyewear, the frame portion retaining a lens within a lens retainer and surrounding the lens such that part of the frame portion is interposed between the lens retaining groove and the groove;
- and
- applying an impact dispersing material to extend within the groove such that the impact dispersing material does not contact with and is spaced apart from the lens and has the frame portion interposed therebetween.
