Abstract
Dual-frame eyeglasses that include a foundation eyeglass frame that may be worn on the user's head, and a pivot eyeglass frame that is rigidly coupled to the foundation eyeglass frame via a pair of pivot mechanisms. The pivot eyeglass frame may be substantially similar in form and profile to the foundation eyeglass frame. The pivot eyeglass frame may be configured to incrementally rotate about the pivot mechanism from a first position that substantially overlaps a user's line of sight through to a second position that is angularly offset away from the user's line of sight. Additionally, the foundation eyeglass frame may include a nose bridge that separates into two elements at a coupling point on the nose bridge to facilitate each half of the foundation eyeglass frame folding into a separate, compact form.
Claims9
A pair of dual-frame eyeglasses, comprising:
- a pivot eyeglass frame comprising:
- a left focus lens unit and a right focus lens unit;
- a left pivot arm, the left pivot arm further comprising a first left pivot arm end and a second left pivot arm end, the first left pivot arm end being rigidly fixed to a left outer portion of the left focus lens unit via a first left hinge, and the second left pivot arm end of the left pivot arm being rigidly fixed to a left pivot mechanism, the left pivot arm having a pivot thickness dimension that is measured perpendicular to a centroidal axis of the first left hinge;
- a right pivot arm that is a mirror image of the left pivot arm;
- a foundation eyeglass frame comprising:
- a left temple arm that is configured to rest on a head of a wearer of the pair of dual-frame eyeglasses, the left temple arm having a first left temple arm end and a second left temple arm end, wherein the first left temple arm end is rigidly fixed to a left outer portion of the foundation eyeglass frame via a second left hinge, and the second left temple arm end is rigidly fixed to the left pivot mechanism, the left temple arm having a temple thickness dimension that is measured perpendicular to the centroidal axis of the first left hinge, the temple thickness dimension being double the pivot thickness dimension;
- a right temple arm that is the mirror image of the left temple arm;
- and
- the left pivot mechanism being configured to selectively couple the left pivot arm and the left temple arm via a magnetic interaction between a first set of magnets that are rigidly fixed to the left temple arm and a second set of magnets that are rigidly fixed to the left pivot arm, wherein a first number of magnets of the first set of magnets is double that of a second number of magnets of the second set of magnets, and
- wherein, a right pivot mechanism is the mirror image of the left pivot mechanism.
