Abstract

An out-the-front knife, components thereof, and associated methods. The out-the front knife can be a double-action spring-assisted knife. The knife includes a handle and a blade. The handle includes a rear end and a front opening opposite the rear end. The blade is movable with respect to the handle between stowed and deployed positions. In the stowed position, the blade is biased rearward. The knife includes an actuator movable in a deploying direction to spring the blade forward away from the stowed position toward the deployed position.

Claims (25)

1. An out-the-front knife comprising:

a handle having a rear end and a front opening opposite the rear end;

a blade supported by the handle, the blade having a cutting edge, the blade being movable with respect to the handle between a stowed position in the handle and a deployed position in which the blade extends out of the front opening; and

an actuator supported by the handle, the actuator being movable with respect to the handle in a deploying direction to move the blade forward away from the stowed position toward the deployed position;

a blade driver supported by the handle, the blade driver being configured to spring the blade toward the deployed position responsive to movement of the actuator in the deploying direction;

wherein the blade when in the stowed position is biased rearward, and the blade driver includes a blade pusher configured to push the blade forward against said rearward bias responsive to movement of the actuator in the deploying direction, the blade driver being configured to spring the blade toward the deployed position after sufficient forward pushing force is applied to the blade by the blade pusher to overcome the rearward bias.

2. An out-the-front knife as set forth in claim 1 , further comprising a retainer configured to engage the blade in rearward biasing engagement to bias the blade rearward in the stowed position.

3. An out-the front knife as set forth in claim 2 , wherein the blade is configured to push the retainer out of rearward biasing engagement with the blade when sufficient force is applied to the actuator in the deploying direction.

4. An out-the-front knife as set forth in claim 3 , wherein the blade includes a ramp configured to push the retainer out of rearward biasing engagement with the blade when sufficient force is applied to the actuator in the deploying direction.

5. An out-the-front knife as set forth in claim 3 , wherein the knife is free of structure, other than the blade, configured to engage the retainer to move the retainer out of rearward biasing engagement with the blade.

6. An out-the-front knife as set forth in claim 2 , wherein the retainer comprises a cam configured to cam against the blade to convert a lateral bias of the cam to the rearward bias of the blade in the stowed position.

7. An out-the-front knife as set forth in claim 6 , wherein the blade includes a ramp and the cam is configured to engage the ramp to bias the blade rearward when the blade is in the stowed position.

8. An out-the-front knife as set forth in claim 2 , wherein the retainer is retractable from a retaining position in engagement with the blade to a retracted position, the retainer being configured for non-pivoting movement from the retaining position to the retracted position.

9. An out-the-front knife as set forth in claim 2 , wherein the retainer is retractable from a retaining position in engagement with the blade to a retracted position, the retainer being configured for generally linear movement from the retaining position to the retracted position.

10. An out-the-front knife as set forth in claim 1 , wherein the blade driver includes at least one spring, and the blade driver is configured to create spring force in the spring to spring the blade toward the deployed position responsive to movement of the actuator in the deploying direction.

11. An out-the-front knife as set forth in claim 10 , wherein the blade driver is configured to, responsive to movement of the actuator a first distance in the deploying direction, create spring force in the at least one spring, and the blade driver is configured to, responsive to movement of the actuator beyond the first distance in the deploying direction, cause the blade pusher to begin pushing the blade forward toward the deployed position.

12. An out-the-front knife as set forth in claim 1 , wherein the blade pusher is a first blade pusher, the blade driver including a spring for springing the blade away from the stowed position toward the deployed position, the blade driver including a second blade pusher different from the first blade pusher, the second blade pusher being operatively connected to the spring to transfer spring force from the spring to the blade to spring the blade toward the deployed position, the second pusher being configured to spring the blade toward the deployed position via spring force from the spring after sufficient forward pushing force is applied to the blade by the first blade pusher to overcome the rearward bias.

13. An out-the-front knife as set forth in claim 12 , wherein the blade driver is configured to, responsive to movement of the actuator a first distance in the deploying direction, create spring force in the spring for springing the blade toward the deployed position, and the blade driver is configured to, responsive to movement of the actuator beyond the first distance in the deploying direction, cause the first blade pusher to begin pushing the blade forward toward the deployed position.

14. An out-the-front knife as set forth in claim 12 , wherein the actuator is movable with respect to the handle in a stowing direction to move the blade rearward away from the deployed position toward the stowed position.

15. An out-the-front knife as set forth in claim 12 , further comprising a retainer configured to engage the blade in rearward biasing engagement to bias the blade rearward in the stowed position.

16. An out-the front knife as set forth in claim 15 , wherein the blade is configured to push the retainer out of rearward biasing engagement with the blade when sufficient force is applied to the actuator in the deploying direction.

17. An out-the-front knife as set forth in claim 16 , wherein the blade includes a ramp configured to push the retainer out of rearward biasing engagement with the blade when sufficient force is applied to the actuator in the deploying direction to overcome the rearward bias.

18. An out-the-front knife as set forth in claim 16 , wherein the knife is free of structure, other than the blade, configured to engage the retainer move the retainer out of rearward biasing engagement with the blade.

19. An out-the-front knife as set forth in claim 15 , wherein the retainer comprises a cam configured to cam against the blade to convert a lateral bias of the cam to the rearward bias of the blade in the stowed position.

20. An out-the-front knife as set forth in claim 1 , wherein when the blade is in the stowed position, the actuator is in an at-rest position from which the actuator is movable in the deploying direction.
