Abstract

A switchblade includes a casing that defines a cavity. A blade having a cutting edge 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. An actuator is slidably engaged with the casing. A slider inside the cavity defines a tab on a first side of the slider and engaged with the actuator and front and rear sloped surfaces on a second side of the slider. A front operator and a rear operator are inside the cavity, and a spring connects the front operator to the rear operator. A front lock on the second side of the slider inside the cavity is engaged with the blade in the deployed position. A rear lock on the second side of the slider inside the cavity is engaged with the blade in the retracted position.

Claims (46)

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;

an actuator slidably engaged with said casing;

a slider inside said cavity of said casing, wherein said slider defines a tab on a first side of said slider and engaged with said actuator, a front sloped surface on a second side of said slider opposite said first side, and a rear sloped surface on said second side of said slider;

a front operator inside said cavity;

a rear operator inside said cavity;

a spring connecting said front operator to said rear operator;

a front lock on said second side of said slider inside said cavity engaged with said blade in said deployed position; and

a rear lock on said second side of said slider inside said cavity engaged with said blade in said retracted position.

2. The switchblade as in claim 1 , wherein said casing defines a longitudinal recess, and at least a portion of the front operator, the rear operator, and the spring reside in said longitudinal recess of said casing.

3. The switchblade as in claim 1 , wherein said slider has a uniform thickness between said first side and said second side.

4. The switchblade as in claim 1 , wherein said slider defines a longitudinal channel through said slider between said first and second sides, and at least a portion of said spring is located in said longitudinal channel.

5. The switchblade as in claim 4 , wherein said longitudinal channel has a longitudinal midpoint with a reduced width.

6. The switchblade as in claim 1 , wherein said rear operator engages with said blade to move said blade to said deployed position, and said front operator engages with said blade to move said blade to said retracted position.

7. The switchblade as in claim 1 , wherein said rear sloped surface on said second side of said slider disengages said rear lock from said blade to allow said blade to move to said deployed position, and said front sloped surface on said second side of said slider disengages said front lock from said blade to allow said blade to move to said retracted position.

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 front operator inside said cavity, wherein said front operator engages with said blade to move said blade to said retracted position;

a rear operator inside said cavity, wherein said rear operator engages with said blade to move said blade to said deployed position;

a spring connecting said front operator to said rear operator;

an actuator slidably engaged with said casing,

a slider inside said cavity of said casing, wherein said slider defines a tab on a first side of said slider and engaged with said actuator, a front sloped surface on a second side of said slider opposite said first side, and a rear sloped surface on said second side of said slider; and

wherein said slider has a uniform thickness between said first side and said second side.

9. The switchblade as in claim 8 , wherein said casing defines a longitudinal recess, and at least a portion of the front operator, the rear operator, and the spring reside in said longitudinal recess of said casing.

10. The switchblade as in claim 8 , wherein said slider defines a longitudinal channel through said slider between said first and second sides, and at least a portion of said spring is located in said longitudinal channel.

11. The switchblade as in claim 10 , wherein said longitudinal channel has a longitudinal midpoint with a reduced width.

12. The switchblade as in claim 8 , wherein said rear operator engages with said slider to move said blade to said retracted position, and said front operator engages with said slider to move said blade to said deployed position.

13. The switchblade as in claim 8 , further comprising a front lock on said second side of said slider inside said cavity engaged with said blade in said deployed position, and a rear lock on said second side of said slider inside said cavity engaged with said blade in said retracted position.

14. The switchblade as in claim 13 , wherein said front sloped surface on said second side of said slider disengages said front lock from said blade to allow said blade to move to said retracted position, and said rear sloped surface on said second side of said slider disengages said rear lock from said blade to allow said blade to move to said deployed position.

15. 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;

an actuator slidably engaged with said casing;

a slider inside said cavity of said casing, wherein said slider defines a tab on a first side of said slider and engaged with said actuator, a front sloped surface on a second side of said slider opposite said first side, and a rear sloped surface on said second side of said slider; and

a front operator inside said cavity, wherein said front operator engages with said slider to move said blade to said deployed position;

a rear operator inside said cavity, wherein said rear operator engages with said slider to move said blade to said retracted position;

a spring connecting said front operator to said rear operator;

a front lock on said second side of said slider inside said cavity engaged with said blade in said deployed position; and

a rear lock on said second side of said slider inside said cavity engaged with said blade in said retracted position.

16. The switchblade as in claim 15 , wherein said casing defines a longitudinal recess, and at least a portion of the front operator, the rear operator, and the spring reside in said longitudinal recess of said casing.

17. The switchblade as in claim 15 , wherein said slider defines a longitudinal channel through said slider between said first and second sides, and at least a portion of said spring is located in said longitudinal channel.

18. The switchblade as in claim 17 , wherein said longitudinal channel has a longitudinal midpoint with a reduced width.

19. The switchblade as in claim 15 , wherein said rear operator engages with said blade to move said blade to said deployed position, and said front operator engages with said blade to move said blade to said retracted position.

20. The switchblade as in claim 15 , wherein said rear sloped surface on said second side of said slider disengages said rear lock from said blade to allow said blade to move to said deployed position, and said front sloped surface on said second side of said slider disengages said front lock from said blade to allow said blade to move to said retracted position.
