Locking screw driver handle
View Patent ↗A driver including a handle, lever, swivel cap, shaft, and a tip mechanically connected to the lever configured to engage a screw. Engaging the lever causes the tip to either compress or expand so as to lock the screw to the driver. According to one exemplary embodiment, the cap can be translated releasing the lever, thereby releasing the screw from the tip. According to one embodiment, the cap is a swivel cap allowing for jeweler style use. Advantages of the present system and method, according to various embodiments, include a tip compressing a feature that is within an outer diameter of the screw allowing a driver, or a portion thereof, to have a maximum diameter equal to or smaller than the maximum diameter of a screw.
1. A screwdriver comprising:
a handle having a proximal end and a distal end;
a shaft including a proximal end and a distal end, wherein said proximal end of said shaft is coupled to said distal end of said handle;
a cap member disposed on said proximal end of said handle;
a tip disposed on said distal end of said shaft;
an actuation member disposed on said handle, wherein said actuation member is configured to selectively actuate said tip, transitioning said tip from a locked position to an unlocked position;
a retention orifice defined on said actuation member; and
a protrusion disposed on a distal end of said cap member;
wherein said cap member is configured to engage said actuation member via said retention orifice when engaged; and
wherein said cap member is configured to release said actuation member from an engaged position when said rotatable cap is slidably translated from said handle.
2. The screwdriver of claim 1 wherein said cap member comprises a rotatable cap disposed on said proximal end of said handle, said rotatable cap being configured to independently rotate with respect to said handle.
3. The screw driver of claim 2 , further comprising a torque gauge incorporated in said screw driver.
4. The screwdriver of claim 1 , wherein said actuation member is configured to selectively retract and advance said tip; and
wherein said tip includes an outer taper;
wherein said selective retraction of said tip into said shaft compresses said tip.
5. The screwdriver of claim 1 , in combination with a fastener, wherein said tip is configured to compress about a feature of said fastener.
6. The screwdriver of claim 5 , wherein said fastener further comprises a head portion having a maximum diameter;
wherein said fastener feature is disposed within said maximum diameter of said fastener.
7. The screwdriver of claim 6 , wherein said shaft further comprises a largest diameter;
wherein said tip includes a largest diameter; and
wherein said largest diameter of said shaft and said largest diameter of said tip are both at least as small as said maximum diameter of said fastener.
8. The screwdriver of claim 1 , in combination with a fastener, wherein said actuation member is configured to selectively cause said tip to expand and contract;
wherein said tip is configured to expand within a feature of said fastener to secure said fastener to said tip.
9. The screwdriver of claim 1 , wherein said tip is configured to couple with at least one feature of a fastener.
10. The screwdriver of claim 9 , wherein said tip compressively engages said feature to secure said fastener to said tip.
11. The screwdriver of claim 9 , wherein said tip is configured to expand within said feature to secure said fastener to said tip.
12. A screwdriver comprising:
a handle having a proximal end and a distal end;
a shaft including a proximal end and a distal end, wherein said proximal end of said shaft is coupled to said distal end of said handle;
a tip translation member including a proximal and a distal end slideably positioned within said shaft;
a tip disposed on said distal end of said tip translation member proximate said distal end of said shaft, said tip being movable from a locked position to an unlocked position;
an actuation member pivotably disposed on said handle, said actuation member rotatably coupled to said proximal end of said tip translation member;
a retention orifice defined on said actuation member; and
a protrusion disposed on a distal end of a cap member disposed on said proximal end of said handle;
wherein said protrusion is configured to releaseably couple with said retention orifice to secure or release said actuation member, and
wherein said actuation member is configured to selectively actuate said tip, via said tip translation member, between said locked position and said unlocked position.
13. The screwdriver of claim 12 , wherein said actuation member is configured to selectively retract and advance said tip in relation to said shaft;
wherein said tip includes an outer taper; and
wherein said selective retraction of said tip into said shaft compresses said tip in a locked position.
14. The screwdriver of claim 12 , wherein said tip is configured to couple with at least one feature of a fastener.
15. The screwdriver of claim 14 , wherein said tip compressively engages said feature to secure said fastener to said tip.
16. The screwdriver of claim 14 , wherein said tip is configured to expand within said feature to secure said fastener to said tip.
17. The screwdriver of claim 12 , wherein said actuation member is rotatable between a first position and a second position, wherein in said first position said tip is in said unlocked position and in said second position said tip is in said locked position.
18. The screwdriver of claim 12 , wherein said tip comprises two or more tip members.
