Rotation of the first rotating element rotates a second rotating element, releasing the second rotating element from the ratchet teeth of the handcuff strand and allowing release of the handcuff strand when both of the pair of buttons are depressed. ## Claims ### Claim 1 A handcuff comprising: a handcuff strand comprising ratchet teeth; a pair of buttons on opposing sides of the handcuff, the pair of buttons connected by a button joining element; and a spring configured to receive rotational force from a key and cause rotation of a first rotating element; wherein the first rotating element rotates about the button joining element, and rotation of the first rotating element about the button joining element rotates a second rotating element, releasing the second rotating element from the ratchet teeth of the handcuff strand and allowing release of the handcuff strand when both of the pair of buttons are depressed. ### Claim 2 (depends on 1) The handcuff of claim 1, wherein the button joining element comprises a further spring. ### Claim 3 (depends on 2) The handcuff of claim 2, wherein the further spring passes through an opening in the first rotating element. ### Claim 4 (depends on 1) The handcuff of claim 1, further comprising a star wheel configured to engage the ratchet teeth of the handcuff strand and inhibit a foreign object from contacting the second rotating element. ### Claim 5 (depends on 1) The handcuff of claim 1, further comprising a key action spring configured to maintain the second rotating element in a position inhibiting movement of the ratchet teeth of the handcuff strand. ### Claim 6 (depends on 1) The handcuff of claim 1, further comprising a top double strand through which the key passes and configured to receive a first button of the pair of buttons. ### Claim 7 (depends on 6) The handcuff of claim 6, further comprising a bottom double strand configured to receive a second button of the pair of buttons. ### Claim 8 (depends on 7) The handcuff of claim 7, further comprising a star wheel element configured to join the top double strand and the bottom double strand, engage the ratchet teeth of the handcuff strand, and inhibit a foreign object from contacting the second rotating element. ### Claim 9 A handcuff comprising: a handcuff strand comprising ratchet teeth; a pair of buttons connected by a button joining element, each button of the pair of buttons positioned within a respective opposite facing exterior strand of the handcuff; and a spring configured to receive rotational force from a key and cause rotation of a first rotating element; wherein the first rotating element rotates about the button joining element, and rotation of the first rotating element about the button joining element rotates a second rotating element, releasing the second rotating element from the ratchet teeth of the handcuff strand and allowing release of the handcuff strand when both of the pair of buttons are depressed. ### Claim 10 (depends on 9) The handcuff of claim 9, wherein the button joining element comprises a further spring. ### Claim 11 (depends on 10) The handcuff of claim 10, wherein the further spring passes through an opening in the first rotating element. ### Claim 12 (depends on 9) The handcuff of claim 9, further comprising a star wheel configured to engage the ratchet teeth of the handcuff strand and inhibit a foreign object from contacting the second rotating element. ### Claim 13 (depends on 9) The handcuff of claim 9, further comprising a key action spring configured to maintain the second rotating element in a position inhibiting movement of the ratchet teeth of the handcuff strand. ### Claim 14 (depends on 9) The handcuff of claim 9, further comprising a star wheel element configured to join the top double strand and the bottom double strand, engage the ratchet teeth of the handcuff strand, and inhibit a foreign object from contacting the second rotating element. ### Claim 15 A handcuff comprising: a handcuff strand comprising ratchet teeth; a first button positioned within a first double strand element, the first button positioned proximate to and opposite a second button positioned within a second double strand element; a button joining element located between the first button and the second button; and a spring configured to receive rotational force from a key and cause rotation of a first rotating element; wherein the first rotating element rotates about the button joining element, and rotation of the first rotating element about the button joining element rotates a second rotating element, releasing the second rotating element from the ratchet teeth of the handcuff strand and allowing release of the handcuff strand when the first button and the second button are depressed. ### Claim 16 (depends on 15) The handcuff of claim 15, wherein the button joining element comprises a further spring. ### Claim 17 (depends on 16) The handcuff of claim 16, wherein the further spring passes through an opening in the first rotating element. ### Claim 18 (depends on 15) The handcuff of claim 15, further comprising a star wheel configured to engage the ratchet teeth of the handcuff strand and inhibit a foreign object from contacting the second rotating element. ### Claim 19 (depends on 15) The handcuff of claim 15, further comprising a key action spring configured to maintain the second rotating element in a position inhibiting movement of the ratchet teeth of the handcuff strand. ### Claim 20 (depends on 15) The handcuff of claim 15, further comprising a star wheel element configured to join the first double strand element and the second double strand element, engage the ratchet teeth of the handcuff strand, and inhibit a foreign object from contacting the second rotating element.
