Switchblade
A switchblade includes a casing that defines a cavity and a blade having a cutting edge. The blade has a retracted position in which the cutting edge is inside the cavity and a deployed position in which the cutting edge is outside of the cavity. A spring is operably connected to the blade to bias the blade to the deployed position. An actuator extends through at least a portion of the casing and has a hold position that engages with the blade to prevent movement of the blade with respect to the casing and a release position that permits movement of the blade with respect to the casing. A safety is operably connected to the actuator and has a lock position that prevents operation of the actuator and an unlock position that permits operation of the actuator.
1. A switchblade, comprising:
a casing, wherein said casing defines a cavity;
a blade having a cutting edge, wherein said blade has a retracted position in which said cutting edge is inside said cavity and a deployed position in which said cutting edge is outside of said cavity;
a spring operably connected to said blade to bias said blade to said deployed position;
an actuator that extends through at least a portion of said casing, wherein said actuator has a hold position that engages with said blade so that said actuator prevents movement of said blade with respect to said casing and a release position that permits movement of said blade with respect to said casing; and
a safety operably connected to said actuator, wherein said safety has a lock position that prevents operation of said actuator and an unlock position that permits operation of said actuator, wherein said safety is biased in said lock position.
2. The switchblade as in claim 1 , wherein said safety defines a projection, said casing defines a recess, and said projection of said safety is engaged with said recess of said casing when said safety is in said lock position and disengaged from said recess when said safety is in said unlock position.
3. The switchblade as in claim 1 , wherein said safety moves in a first direction from said lock position to said unlock position, said actuator moves in a second direction from said hold position to said release position, and said first direction is perpendicular to said second direction.
4. The switchblade as in claim 1 , wherein said blade moves parallel to a longitudinal axis of said cavity when said blade moves from said retracted position to said deployed position.
5. The switchblade as in claim 1 , further comprising a charging handle in sliding engagement with said casing, wherein said charging handle moves with respect to said casing to engage said blade to overcome said spring bias to move said blade to said retracted position.
6. The switchblade as in claim 5 , further comprising a releasable latch between said charging handle and said casing.
7. The switchblade as in claim 6 , wherein said releasable latch is pivotally connected to said charging handle.
8. A switchblade, comprising:
a casing, wherein said casing defines a cavity;
a blade having a cutting edge, wherein said blade has a retracted position in which said cutting edge is inside said cavity and a deployed position in which said cutting edge is outside of said cavity;
a spring operably connected to said blade to bias said blade to said deployed position;
an actuator releasably engaged with said blade, wherein said actuator has a hold position that engages with said blade so that said actuator prevents movement of said blade with respect to said casing and a release position that permits movement of said blade with respect to said casing;
a safety operably connected to said actuator, wherein said safety has a lock position that prevents operation of said actuator and an unlock position that permits operation of said actuator; and
said safety defines a projection, said casing defines a recess, and said projection of said safety is engaged with said recess of said casing when said safety is in said lock position and disengaged from said recess when said safety is in said unlock position.
9. The switchblade as in claim 8 , wherein said safety is biased in said lock position.
10. The switchblade as in claim 8 , wherein said safety moves in a first direction from said lock position to said unlock position, said actuator moves in a second direction from said hold position to said release position, and said first direction is perpendicular to said second direction.
11. The switchblade as in claim 8 , wherein said blade defines a detent that engages with said actuator in said hold position.
12. The switchblade as in claim 8 , wherein said spring moves said blade linearly when said actuator is placed in said release position.
13. The switchblade as in claim 8 , further comprising a charging handle in sliding engagement with said casing, wherein said charging handle moves with respect to said casing to engage said blade to overcome said spring bias to move said blade to said retracted position.
14. The switchblade as in claim 13 , further comprising a releasable latch between said charging handle and said casing.
15. The switchblade as in claim 14 , wherein said releasable latch is pivotally connected to said charging handle.
