Abstract

An anti-slip fastener remover tool includes a torque-tool body, a plurality of paired engagement features, and a plurality of intersection points. The plurality of paired engagement features that grips the lateral surface of the stripped fastener head is radially positioned around a rotation axis of the torque-tool body. The torque-tool body is inwardly extended from an outer wall of the torque-tool body to the plurality of paired engagement features. Each paired engagement feature comprises a first engagement feature and a second engagement feature. The first engagement feature and the second engagement feature each comprise a bracing section, a cavity section, and a connector section. The cavity sections of the first and second engagement features are adjacently connected to each other. The bracing sections of the first and second engagement feature are oppositely positioned about the cavity sections of the first and second engagement features.

First claim

What is claimed is:

1 . An anti-slip fastener remover tool comprises:
a torque-tool body; a plurality of paired engagement features; a plurality of intersection points; the torque-tool body being inwardly extended from an outer wall of the torque-tool body to the plurality of paired engagement features; the plurality of paired engagement features comprising an arbitrary paired engagement feature and an adjacent paired engagement feature; each of the plurality of paired engagement features comprising a first engagement feature and a second engagement feature; a number of the plurality of paired engagement features being six; a cross section for the first engagement feature and the second engagement feature each comprising a bracing section, a cavity section, and a connector section; the plurality of paired engagement features being radially distributed about a rotational axis of the torque-tool body; a first base being an opening of the torque-tool body; a second base being within the torque-tool body, opposite the first base, and comprising an innermost wall; the plurality of paired engagement features being perimetrically connected around the first base, extending from the first base to the second base; each of the plurality of paired engagement features being configured to simultaneously engage about the center of a fastener lateral surface along the first base to the second base; each of the plurality of paired engagement features being equal in length measured along a distance parallel with the rotational axis extending from the first base to the innermost wall; a third angle delineated between the bracing section of the first engagement feature of the arbitrary paired engagement feature and the bracing section of the second engagement feature of the adjacent paired engagement feature being less than 180 degrees; the bracing section of the first engagement feature for each of the plurality of paired engagement features being connected to the cavity section of the first engagement feature by the connector section of the first engagement feature; the bracing section of the second engagement feature for each of the plurality of paired engagement features being connected to the cavity section of the second engagement feature by the connector section of the second engagement feature; the cavity section of the first engagement feature for each of the plurality of paired engagement features being adjacently connected to the cavity section of the second engagement feature of each of the plurality of paired engagement features; the bracing section of the first engagement feature of the arbitrary paired engagement feature being connected to the bracing section of the second engagement feature of the adjacent paired engagement feature by one of the plurality of intersection points; and the cavity section of the first engagement feature and the cavity section of the second engagement feature being oriented away from the rotational axis for each of the plurality of paired engagement features.

2 . The anti-slip remover tool of claim 1 , wherein the each of the plurality of intersection points is a sharp point.

3 . The anti-slip remover tool of claim 1 , wherein the each of the plurality of intersection points is a curved section.

4 . The anti-slip remover tool of claim 1 , further comprising:
the plurality of intersection points each further comprising a third segment; and the third segment being flat.

5 . The anti-slip remover tool of claim 4 , further comprising:
the plurality of intersection points comprising an arbitrary third segment and an opposite third segment; and the arbitrary third segment being oppositely positioned about the torque-tool body from the opposite third segment.

6 . The anti-slip remover tool of claim 5 , wherein the arbitrary third segment and the opposite third segment are parallel.

7 . The anti-slip remover tool of claim 5 , wherein the arbitrary third segment and the opposite third segment are not parallel.

8 . The anti-slip remover tool of claim 1 , further comprising:
the plurality of paired engagement features further comprising a distant paired engagement feature; and the bracing section of the first engagement feature of the adjacent paired engagement feature being connected to a bracing section of the second engagement feature of the distant paired engagement feature by one of the plurality of intersection points.

9 . The anti-slip remover tool of claim 8 , wherein the bracing section of first engagement feature of the arbitrary paired engagement feature is offset from the bracing section of the second engagement feature of the distant paired engagement feature.

10 . The anti-slip remover tool of claim 1 , wherein the bracing section of the first engagement feature and the second engagement feature of the plurality of paired engagement features is concave.

11 . The anti-slip remover tool of claim 1 , wherein the bracing section of the first engagement feature and the second engagement feature of the plurality of paired engagement features is convex.

12 . The anti-slip remover tool of claim 1 , wherein the connector section is colinear with the bracing section for each of the plurality of paired engagement features.

13 . The anti-slip remover tool of claim 1 , wherein the bracing section is colinear with a tangent line to the cavity section at an intersection of the cavity section and the connector section for each of the plurality of paired engagement features.

14 . The anti-slip remover tool of claim 1 , wherein the third angle is less than 90 degrees.

15 . The anti-slip remover tool of claim 1 , further comprising:
a first length being a length of the bracing section of the first engagement feature for any cross section of the torque-tool body parallel to the first base and the second base; a second length being a length of the bracing section of the second engagement feature for any cross section of the torque-tool body parallel to the first base and the second base; and the first length being equal to the second length.

16 . The anti-slip remover tool of claim 1 , further comprising:
a first length being a length of the bracing section of the first engagement feature for any cross section of the torque-tool body parallel to the first base and the second base; a second length being a length of the bracing section of the second engagement feature for any cross section of the torque-tool body parallel to the first base and the second base; and the first length being greater than or less than the second length.

17 . The anti-slip fastener remover tool as claimed in claim 1 , wherein the connector section is a concave segment, wherein the connector section is oriented toward the rotational axis.

18 . The anti-slip fastener remover tool as claimed in claim 1 , wherein the bracing section of the first engagement feature and the bracing section of the second engagement feature are positioned offset of each other.

19 . The anti-slip fastener remover tool as claimed in claim 1 , comprising:
an engagement bore; an attachment body; the attachment body being centrally positioned around and along the rotational axis; the attachment body being adjacently connected to the torque-tool body; and the engagement bore traversing into the attachment body along the rotational axis, opposite of the torque-tool body.
