ACCESSORIES THEREFOR; HANDCUFFS ## Abstract A prisoner transport kit is described including handcuffs, ankle cuffs, fetters, and locks for use in transporting a prisoner. ## Claims ### Claim 1 A prisoner transport kit, the kit comprising: a pair of rigid handcuffs; a lock; and a prisoner transport fetter; the lock comprising: a tongue-face defining a lock opening that is dimensioned to accept a tongue from the prisoner transport fetter; a locking mechanism which prevents removal of the tongue from the lock opening when the tongue is inserted a predetermined distance into the lock opening and the locking mechanism is in a locking position; and a key-face having a keyhole, the key-face being a different face of the lock than the tongue-face, the keyhole being dimensioned to accept a key that is adapted to engage the lock and to move the locking mechanism from the locking position, thereby allowing the removal of the tongue from the lock opening; the prisoner transport fetter having first and second opposing ends, the fetter comprising: the tongue, the tongue being located at the first end of the fetter and comprising a locking feature, the locking feature engaging with the locking mechanism when the tongue is inserted the predetermined distance into the lock opening and the locking mechanism is in the locking position; and a plurality of fetter openings spaced apart from each other along a length of the fetter, wherein the tongue can be inserted through one of the fetter openings before being inserted into the lock opening; and the pair of rigid handcuffs defining a channel that is dimensioned to allow the tongue to pass through the channel but not to allow the lock to pass through the channel. ### Claim 2 (depends on 1) The prisoner transport kit of claim 1, further comprising an attaching mechanism at the second end of the fetter, the attaching mechanism being capable of attaching the second end of the fetter to one of the fetter openings. ### Claim 3 (depends on 2) The prisoner transport kit of claim 2, wherein the fetter comprises a chain; spaces defined by links of the chain comprise the fetter openings; and the attaching mechanism comprises a clip. ### Claim 4 (depends on 3) The prisoner transport kit of claim 3, wherein the chain comprises stainless steel. ### Claim 5 (depends on 2) The prisoner transport kit of claim 2, wherein the fetter comprises a fiber belt; button holes in the belt comprise the fetter openings; and the attaching mechanism comprises a button. ### Claim 6 (depends on 5) The prisoner transport kit of claim 5, wherein the fiber belt is stretch-resistant, abrasion-resistant, and cut-resistant. ### Claim 7 (depends on 5) The prisoner transport kit of claim 5, where fiber of the fiber belt is selected from a group consisting of aramid and ultra-high-molecular-weight polyethylene. ### Claim 8 (depends on 5) The prisoner transport kit of claim 5, where the fiber belt is a polyester webbing. ### Claim 9 (depends on 1) The prisoner transport kit of claim 1, the locking feature comprising an opening in the tongue. ### Claim 10 (depends on 1) The prisoner transport kit of claim 1, the locking feature comprising a protrusion depending from a remainder of the tongue. ### Claim 11 (depends on 1) The prisoner transport kit of claim 1, further comprising another tongue at the second end of the fetter, the other tongue comprising a locking feature that is structured and dimensioned to engage with a locking mechanism of another lock when the other tongue is inserted the predetermined distance into a lock opening of the other lock and the locking mechanism of the other lock is in a locking position. ### Claim 12 (depends on 11) The prisoner transport kit of claim 11, further comprising the other lock. ### Claim 13 (depends on 11) The prisoner transport kit of claim 11, further comprising: a pair of ankle cuffs; and a center ring, each one of the pair of ankle cuffs being chained to the center ring, and the center ring being large enough for the other tongue at the second end of the fetter to pass through the center ring; wherein the second tongue can be inserted through a selected one of the fetter openings before being inserted into the lock opening of the other lock, and the fetter is long enough to encircle a prisoner's torso, with the tongue at the first end of the fetter inserted through one of the fetter openings before being inserted into the lock opening of the lock, and for the other tongue at the second end of the fetter to pass through the center ring before being inserted through the selected one of the fetter openings before being inserted into the lock opening of the other lock. ### Claim 14 A prisoner transport fetter having first and second opposing ends, the fetter comprising: a tongue located at the first end of the fetter and comprising a locking feature, the tongue having a length axis greater than a width axis, the width axis being greater than a height axis, the tongue having a first area in a plane defined by the length axis and the width axis, the locking feature having a second area in the plane, the first area being at least three times greater than the second area, and the locking feature being structured and dimensioned to engage with a locking mechanism of a lock when the tongue is inserted a predetermined distance into a lock opening of the lock while the locking mechanism is in a locking position; and a plurality of fetter openings spaced apart from each other along a length of the fetter, wherein the tongue can be inserted through one of the fetter openings before being inserted into the lock opening. ### Claim 15 (depends on 14) The prisoner transport fetter of claim 14, further comprising an attaching mechanism at the second end of the fetter, the attaching mechanism being capable of attaching the second end of the fetter to one of the fetter openings. ### Claim 16 (depends on 15) The prisoner transport fetter of claim 15, wherein the fetter comprises a chain; spaces defined by links of the chain comprise the fetter openings; and the attaching mechanism comprises a clip. ### Claim 17 (depends on 16) The prisoner transport fetter of claim 16, wherein the chain comprises stainless steel. ### Claim 18 (depends on 15) The prisoner transport fetter of claim 15, wherein the fetter comprises a fiber belt; button holes in the belt comprise the fetter openings; and the attaching mechanism comprises a button. ### Claim 19 (depends on 18) The prisoner transport fetter of claim 18, wherein the fiber belt is stretch-resistant, abrasion-resistant, and cut-resistant. ### Claim 20 (depends on 18) The prisoner transport fetter of claim 18, where fiber of the fiber belt is selected from a group consisting of aramid and ultra-high-molecular-weight polyethylene. ### Claim 21 (depends on 18) The prisoner transport fetter of claim 18, where the fiber belt is a polyester webbing. ### Claim 22 (depends on 14) The prisoner transport fetter of claim 14, the locking feature comprising an opening in the tongue. ### Claim 23 (depends on 14) The prisoner transport fetter of claim 14, the locking feature comprising a protrusion depending from a remainder of the tongue. ### Claim 24 (depends on 14) The prisoner transport fetter of claim 14, further comprising another tongue located at the second end of the fetter and comprising a locking feature that is structured and dimensioned to engage with a locking mechanism of another lock when the other tongue is inserted the predetermined distance into a lock opening of the other lock and the locking mechanism of the other lock is in a locking position.
