Abstract
As disclosed herein, a bidirectional ratchet for an anti-slippage knob-ratchet to adjust strap length for securing a virtual reality headset onto the head of a user is provided. In one aspect, the bidirectional ratchet may include a first pawl, configured to engage with a stationary ratchet drum in an outer housing to allow movement of a pinion in a clockwise direction. The bidirectional rachet may include a second pawl, configured to engage with the stationary ratchet drum to allow movement of the pinion in a counterclockwise direction. A knob system and a headset are also provided.
Claims18
A ratchet, comprising:
- a first pawl, configured to engage with a stationary ratchet drum in an outer housing to allow movement of a pinion in a clockwise direction, wherein the pinion is coupled to the ratchet by a spring;
- and
- a second pawl, configured to engage with the stationary ratchet drum to allow a movement of the pinion in a counterclockwise direction.
A knob system for adjusting a strap length of a headset, comprising:
- a rotating cap, including:
- a strap-lengthening configuration,
- a strap-shortening configuration, and
- a strap-locking configuration;
- a ratchet coupled to the rotating cap and configured to rotate in a first direction when the rotating cap is in the strap-lengthening configuration, to rotate in a second direction when the rotating cap is in the strap-shortening configuration, and to remain in a fixed position when the rotating cap is in the strap-locking configuration;
- a pinion coupled to the ratchet at a hub, to a left headset strap on a first edge of the left headset strap, and to a right headset strap on a second edge of the right headset strap, wherein the pinion is coupled to the ratchet by a spring;
- and
- a housing, including:
- a strap coupling to receive the left headset strap and the right headset strap, and
- a stationary ratchet drum to engage with the ratchet in a stop-hold configuration when the rotating cap is in the strap-lengthening configuration or in the strap-shortening configuration, and in a lock configuration when the rotating cap is in the strap-locking configuration.
A headset, comprising:
- a visor, including a display configured to provide an immersive reality view to a user;
- a left strap attached to a left side of the visor;
- and
- a right strap attached to a right side of the visor, the left strap and the right strap coupled on an opposite side of the visor via a knob, the knob including a bidirectional ratchet, wherein:
- the bidirectional ratchet includes multiple pawls disposed around a pinion coupled to the bidirectional ratchet by a spring, and
- the bidirectional ratchet enables a strap-lengthening configuration, a strap-shortening configuration, and a strap-locking configuration.
