Abstract

A pin extractor is disclosed. The pin extractor can comprise a press to act against a clip securing a pin to be extracted. The press can have a clip interface feature at an end of the press configured to compress the clip radially inward upon application of a force against the clip. The pin extractor can also comprise a puller having a claw to engage the pin. The puller can be movable relative to the press to extract the pin as the press compresses the clip radially inward.

First claim

What is claimed is:

1. A pin extractor, comprising:
a press to act against a clip securing a pin to be extracted, the press having
a lower portion with a clip interface feature at an end of the press configured to compress the clip radially inward upon application of a force against the clip, and
an upper portion having a ramp;

a puller slidably coupled to the press; and
a claw, pivotally coupled to the puller, with a first end to engage the pin, and a second end opposite the first end that interfaces with the ramp, wherein the puller and the claw are simultaneously slidably movable relative to the press to extract the pin as the press compresses the clip radially inward, and the ramp interface with the second end of the claw forces the claw to pivot toward an engaged position with the pin.

2. The pin extractor of claim 1 , wherein the clip interface feature is configured to contact and slide over the clip to compress the clip radially inward upon the application of the force against the clip.

3. The pin extractor of claim 1 , further comprising an opening defined at least in part by a rim of the clip interface feature to receive at least a portion of the clip as the rim slides over the clip.

4. The pin extractor of claim 1 , wherein the end of the press is configured to facilitate passage of the pin about the press upon extraction of the pin.

5. The pin extractor of claim 4 , wherein the end of the press comprises a cylindrical configuration.

6. The pin extractor of claim 1 , wherein the claw is biased toward an engaged position.

7. The pin extractor of claim 1 , wherein an upper portion of the press further comprises a claw interface surface proximate the ramp that interfaces with the second end of the claw to maintain the claw in the engaged position as the puller moves relative to the press.

8. The pin extractor of claim 1 , wherein the claw comprises an opening defined by first and second protrusions, the opening being configured to receive a neck of the pin and the first and second protrusions being configured to engage a head of the pin.

9. The pin extractor of claim 1 , wherein the press comprises a handle at an end opposite the clip interface feature to interface with a palm of a user to apply the force against the clip.

10. The pin extractor of claim 9 , wherein the puller comprises a grasping feature to interface with a finger of a user to move the puller relative to the press.

11. The pin extractor of claim 10 , wherein the grasping feature and the handle are biased away from one another.

12. The pin extractor of claim 1 , wherein the press and the puller are constrained to sliding relative movement by a pin and channel configuration.

13. A pin extraction system, comprising:
a pin to be extracted;
a clip securing the pin; and
a pin extractor, including
a press to act against the clip, the press having a lower portion with a clip interface feature at an end of the press configured to compress the clip radially inward upon application of a force against the clip, and an upper portion having a ramp, and
a puller slidably coupled to the press; and
a claw, pivotally coupled to the puller, with a first end to engage the pin, and a second end opposite the first end that interfaces with the ramp, wherein the puller and the claw are simultaneously slidably movable relative to the press to extract the pin as the press compresses the clip radially inward, and the ramp interface with the second end of the claw forces the claw to pivot toward an engaged position with the pin.

14. The system of claim 13 , wherein the clip comprises a pin securing portion biased outward to secure the pin.

15. The system of claim 14 , wherein the pin securing portion comprises a plurality of independently movable segments.

16. The system of claim 13 , wherein the pin comprises a base configured to interface with the clip, a neck extending from the base, and a head coupled to the neck.
