Abstract

A head-mountable electronic device can include a viewing frame, a window secured to the viewing frame, a waveguide configured to direct light displayed at the window, and a pair of securement arms extending distally from the viewing frame. Each securement arm of the pair of securement arms can include a splay hinge and a proximal portion connected to the viewing frame at the splay hinge, the proximal portion having a splay range of motion up to 20 degrees outward from a default position and relative to the viewing frame. The splay hinge can apply a force of the proximal portion against a head between 50 Nmm and 90 Nmm within the splay range of motion.

First claim

What is claimed is:

1 . A head-mountable electronic device, comprising:
a viewing frame; a window secured to the viewing frame; a waveguide configured to direct light displayed at the window; and a pair of securement arms extending distally from the viewing frame, each securement arm of the pair of securement arms comprising:
a hinge; and
a proximal portion connected to the viewing frame at the hinge, the proximal portion having a splay range of motion up to 20 degrees outward from a default position and relative to the viewing frame; and
wherein the hinge is configured to apply a force of the proximal portion against a head between 50 Nmm and 90 Nmm within the splay range of motion.

2 . The head-mountable electronic device of claim 1 , wherein:
each securement arm of the pair of securement arms further comprises:
a tip hinge; and
a distal portion connected to the proximal portion at the tip hinge;
the splay range of motion is a first splay range of motion; and
the distal portion includes a second splay range of motion up to 25 degrees outward beyond a default position of the distal portion relative to the proximal portion;
the force is a first force; and the tip hinge is configured to apply a second force of the distal portion against the head between 20 Nmm and 45 Nmm within the second splay range of motion.

3 . The head-mountable electronic device of claim 2 , wherein:
the first splay range of motion is between 4 degrees and 15 degrees; the proximal portion is configured to apply the first force within the first splay range; the second splay range of motion is between 5 degrees and 20 degrees; and the distal portion is configured to apply the second force within the second splay range.

4 . The head-mountable electronic device of claim 3 , wherein:
the first force varies less than 5 percent within the first splay range of motion; and the second force varies less than 5 percent within the second splay range.

5 . The head-mountable electronic device of claim 1 , wherein the hinge comprises:
a cam; and a spring engaging the cam.

6 . The head-mountable electronic device of claim 5 , wherein:
the cam comprises a projection engaging the spring; and the cam is configured to translate relative to the projection.

7 . The head-mountable electronic device of claim 1 , wherein:
the proximal portion defines a first longitudinal axis; and the hinge comprises a compression spring defining a second longitudinal axis disposed perpendicular to the first longitudinal axis.

8 . The head-mountable electronic device of claim 7 , wherein:
the compression spring is a first compression spring; the hinge comprises a second compression spring defining a third longitudinal axis; the third longitudinal axis is disposed perpendicular to the first longitudinal axis; and the first compression spring is disposed adjacent the second compression spring.

9 . The head-mountable electronic device of claim 1 , wherein the hinge comprises a spiral spring.

10 . The head-mountable electronic device of claim 9 , wherein:
the spiral spring is a first spiral spring; and the hinge comprises a second spiral spring.

11 . The head-mountable electronic device of claim 1 , wherein the hinge comprises a spring having an adjustable preload.

12 . The head-mountable electronic device of claim 1 , wherein:
the hinge comprises:
a compression spring; and
a plunger;
the proximal portion comprises a proximal end of the securement arm, the proximal end including an engagement surface engaging the plunger; and when the splay of the securement arm increases past the default position, a distance between where the engagement surface of the securement arm engages the plunger and an axis of rotation of the splay hinge decreases.

13 . A wearable device, comprising:
a frame; and a securement arm extending from the frame, the securement arm comprising:
a distal portion;
a proximal portion coupled to the frame, the proximal portion disposed between the distal portion and the frame; and
a tip hinge rotatably connecting the proximal portion to the distal portion;
wherein:
the distal portion is rotatable outward from a default position of the distal portion relative to the proximal portion;
the tip hinge comprises a spring configured to bias the distal portion toward the default position when the distal portion is rotated outward from the default position; and
the spring includes an adjustable preload.

14 . The wearable device of claim 13 , wherein:
the tip hinge comprises a screw disposed within the securement arm, the screw engaging the spring; and a rotation of the screw adjusts the preload of the spring.

15 . The wearable device of claim 14 , wherein:
the securement arm further comprises a removably attachable cover adjacent to the spring; and removing the cover provides user access to the screw.

16 . The wearable device of claim 13 , wherein:
the securement arm comprises an interchangeable block having a projection configured to engage the spring, the projection having a length; and the preload of the spring is based on the length.

17 . The wearable device of claim 13 , wherein the spring is a compression spring and the preload of the spring is adjustable by compressing or decompressing the compression spring.

18 . A wearable device, comprising:
a frame; a securement arm extending distally from the frame, the securement arm comprising: a proximal portion defining an engagement surface; and a hinge coupling the proximal portion to the frame, the hinge comprising:
a compression spring; and
a plunger;
wherein:
the hinge defines a splay angle range of the proximal portion relative to the frame of 20 degrees beyond a default angle;
the engagement surface is configured to engage the plunger at a contact point to compress the compression spring during a rotation of the securement arm relative to the frame; and
when an angle of the securement arm relative to the frame increases beyond the default angle, a distance between the contact point and an axis of rotation of the hinge decreases.

19 . The wearable device of claim 18 , wherein:
the plunger comprises a first projection; the engagement surface defines a second projection; and the first projection is configured to engage the second projection.

20 . The wearable device of claim 18 , the securement arm further comprising:
a distal portion; and a tip hinge coupling the proximal portion to the distal portion; wherein:
the splay angle range is a first splay angle range;
the default angle is a first default angle;
the tip hinge defines a second splay angle range of the distal portion relative to the proximal portion of 25 degrees beyond a second default angle;
the tip hinge comprises a spring biasing the distal portion toward the second default angle; and
a preload of the spring of the tip hinge is adjustable.
