Abstract
A magnetic latch having a latch arm with a proximal end and a distal end, the proximal pivotally mounted to a butt end of a first handle half, wherein the proximal end of the latch end includes a first magnetic element that is magnetically coupled to the first handle half to preferentially extend the latch arm axially with respect to a long axis of the first handle half, and the distal end including a coupling element. The magnetic latch further having a retention element at the butt and of a second handle half that couples to the coupling element to securely latch the first handle half and the second handle half together. A butterfly knife having a magnetic latch to securely latch the first handle half and the second handle half together, either in in the closed or open position.
Claims18
A butterfly knife having a magnetic latch, comprising:
- a first handle half having a first side wall, a second sidewall, a front end, and a butt end;
- a second handle half having a first side wall, a second sidewall, a front end, a butt end, and a retention element at the butt end;
- a blade having a working end and a tang, wherein the front end of the first handle half and the front end of the second handle half are independently pivotally attached to the tang at independent pivot points;
- and wherein the first handle half and the second handle half can be independently moved to an open position and a closed position;
- and
- a latch arm having a proximal end and a distal end, the proximal end of the latch arm pivotally mounted to the butt end of the first handle half, wherein the proximal end of the latch end comprises a first magnetic element that is magnetically coupled to the first handle half to extend the latch arm axially with respect to a long axis of the first handle half in the absence of an applied force, and the distal end comprising a coupling element that couples to the retention element at the butt end of the second handle half to securely latch the first handle half and the second handle half together, either in in the closed or open position.
A magnetic latch for a folding butterfly knife, comprising:
- a latch arm having a proximal end and a distal end, the proximal end of the latch arm pivotally mounted to a butt end of a first handle half, wherein the proximal end of the latch end comprises a first magnetic element that is magnetically coupled to the first handle half to extend the latch arm axially with respect to a long axis of the first handle half in the absence of an applied force, and the distal end comprising a coupling element;
- and
- a retention element at the butt end of a second handle half, that couples to the coupling element to securely latch the first handle half and the second handle half together.
