Rotatable connector
A rotatable connector formed from two parts, each comprising a body extending from a connecting head having a first face and an opposed second face, the second face having an arcuate tail section on an outer perimeter edge and shaped to be received by a tail socket defined between the first face and a pin extending from a proximal end of the body. When the two parts are engaged, the connecting heads are coaxial to define an axis of rotation. When the parts are rotated on the axis relative to one another, the tail section of the first part travels through the tail socket of the second part and the tail section of the second part travels through the tail socket of the first part, thereby connecting the two parts together. When the parts are rotated in the opposite direction, the parts are disconnected from each other.
1. A rotatable connector ( 200 ) formed from two parts ( 100 ), each part comprising: a body ( 20 ) extending from a connecting head ( 10 ), the bodies ( 20 ) of the two parts ( 100 ) being identical; wherein the connecting head ( 10 ) has a first face ( 11 ) and an opposed second face ( 12 ), characterized in that the second faces of each part ( 12 ) include an arcuate tail section ( 13 ) arranged on an outer perimeter edge of a segment of each connecting head ( 10 ) and each second face is shaped and dimensioned to be received through a tail socket ( 30 ) defined between the first face ( 11 ) and a pin ( 40 ) extending from a proximal end of the body ( 20 ); so that when the two first faces ( 11 ) abut each other, the two parts ( 100 ) are engaged as engaged parts ( 100 ) and the two connecting heads ( 10 ) are coaxial to define an axis of rotation, and when the engaged parts ( 100 ) are rotated relative one to another, the tail section ( 13 ) of the first part travels through the tail socket ( 30 ) of the second part and the tail section ( 13 ) of the second part travels through the tail socket ( 30 ) of the first part, thereby connecting the two parts ( 100 ) together; and when the two parts are rotated in an opposite direction, the two parts are disconnected one from the other.
2. A rotatable connector ( 200 ) according to claim 1 wherein the two parts ( 100 ) are identical.
3. A rotatable connector ( 200 ) according to claim 1 wherein the first face ( 11 ) is planar.
4. A rotatable connector ( 200 ) according to claim 1 wherein the connecting head ( 10 ) has an aperture ( 14 ) through which a hook, carabiner, line, or lanyard can be received.
5. A rotatable connector ( 200 ) according to claim 4 wherein the aperture ( 14 ) is substantially central.
6. A rotatable connector ( 200 ) according to claim 4 wherein the aperture ( 14 ) includes a reinforced ring.
7. A rotatable connector ( 200 ) according to claim 1 wherein the tail section ( 13 ) is tapered from a first end ( 13 A) to a second end.
8. A rotatable connector ( 200 ) according to claim 7 wherein the tail socket ( 30 ) is tapered.
9. A rotatable connector ( 200 ) according to claim 1 formed from a synthetic plastics material.
10. A rotatable connector ( 200 ) according to claim 1 wherein contact surfaces of the tail section ( 13 ) and tail socket ( 30 ) have serrations or teeth formed therein in order to provide a detent mechanism in the form of a rack-and-pinion.
11. A method of connecting two parts ( 100 ) as described in claim 1 including the steps of positioning the two first faces ( 11 ) adjacent one to another so that they abut; and rotating at least one part in a first direction with respect to the other part so that the tail section ( 13 ) of each part enters the tail socket ( 30 ) of the other part.
12. A method of disconnecting two parts ( 100 ) as described in claim 11 having the steps of rotating at least one of the parts in a second direction that is opposite to the first direction so that the tail sections ( 13 ) of each part travel through the tail sockets ( 30 ) of each part until disconnected to separate the parts.
