Abstract
Systems and methods for adjusting a level of force exerted by the temple arm portions of a frame of a head mounted wearable device are provided. Hinge mechanisms that provide for the rotatable coupling of a temple arm portion to a rim portion of a frame of the head mounted wearable device, or glasses, may include a rotation mechanism that facilitates rotation of the temple arm portion relative to the rim portion, and a biasing mechanism that can be adjusted to apply a desired level of lateral force to a head of a user wearing the glasses. The hinge mechanisms may allow for adjustments to biasing rates and/or pre-load levels and/or amounts of temple arm portion rotation prior to engagement to adjust the applied force to desired levels and maintain user comfort.
Claims20
A head mounted wearable device, comprising:
- a frame, including:
- a front frame portion;
- an arm portion coupled to the front frame portion;
- and
- a hinge mechanism rotatably coupling the arm portion to the front frame portion, the hinge mechanism including:
- a rotation mechanism coupled between the front frame portion and the arm portion to rotatably couple the arm portion to the front frame portion of the frame;
- a biasing mechanism coupled to the rotation mechanism and configured to exert a biasing force in response to rotation of the arm portion;
- and
- an adjustment mechanism coupled to at least one of the rotation mechanism or the biasing mechanism and configured to provide for adjustment of at least one of:
- a biasing force exerted by the biasing mechanism;
- or
- a point of engagement of the biasing mechanism during rotation of the arm portion;
- wherein the hinge mechanism includes a friction element configured to output a damping force in response to rotation of the arm portion relative to the front frame portion.
A hinge mechanism, comprising:
- a rotation mechanism coupled between a front frame portion and an arm portion of a frame;
- a biasing mechanism coupled to the rotation mechanism and configured to exert a biasing force in response to rotation of the arm portion;
- and
- an adjustment mechanism coupled to at least one of the rotation mechanism or the biasing mechanism and configured to provide for adjustment of:
- a biasing force exerted by the biasing mechanism;
- a point of engagement of the biasing mechanism during rotation of the arm portion relative to the front frame portion;
- and
- a friction element configured to output a damping force in response to rotation of the arm portion relative to the front frame portion.
