Abstract

An anti-slip torque tool that utilizes a plurality of grooves to prevent slippage and facilitate torque transfer to a fastener. The tool includes a wrench torque-tool body and an at least one engagement element. The wrench torque-tool body includes a plurality of internal sidewalls, a first base, and a second base. Further, each of the internal sidewalls includes a bracing surface. The engagement element includes at least one first groove and at least one second groove, wherein each further includes a primary cavity and a secondary cavity. The engagement element is laterally integrated into a specific sidewall to provide additional gripping action. The first groove and the second groove are positioned offset from each other, along the bracing surface of the specific sidewall. The primary cavity and the secondary cavity each traverse normal and into the bracing surface from the first base to the second base.

First claim

What is claimed is:

1 . An anti-slip torque tool comprises:
a wrench torque-tool body; an at least one engagement element; a second cavity; a third cavity; a fourth cavity; the wrench torque-tool body comprises a plurality of internal sidewalls, a first base, and a second base; each of the plurality of internal sidewalls comprises a first lateral edge, a second lateral edge, and a bracing surface; the engagement element comprises at least one first groove and at least one second groove; the plurality of internal sidewalls being radially distributed about a pivot axis of the wrench torque-tool body; the engagement element being laterally integrated into a specific sidewall from the plurality of internal sidewalls; the engagement element being centrally positioned in between the first lateral edge and the second lateral edge of the specific sidewall; the at least one first groove and the at least one second groove being positioned offset from each other along the bracing surface of the specific sidewall; the second cavity being positioned in between the second lateral edge of the specific sidewall and the at least one second groove; the second cavity traversing normal and into the bracing surface of the specific sidewall; the second cavity being extended from the first base to the second base; the third cavity being positioned adjacent to the first lateral edge of an opposing sidewall from the plurality of internal sidewalls; the third cavity traversing normal and into the bracing surface of the opposing sidewall; the third cavity being extended from the first base to the second base; the fourth cavity being positioned adjacent to the second lateral edge of an opposing sidewall from the plurality of internal sidewalls; the fourth cavity traversing normal and into the bracing surface of the opposing sidewall; the fourth cavity being extended from the first base to the second base; the fourth cavity comprising a convex portion and a concave portion; the convex portion and the concave portion being adjacently connected to each other; the concave portion being positioned adjacent to the second lateral edge of the opposing sidewall from the plurality of internal sidewalls; and the convex portion being positioned adjacent to the bracing surface of the opposing sidewall.

2 . The anti-slip torque tool as claimed in claim 1 comprises:
a wrench handle; and
the wrench handle being externally and laterally connected to the wrench torque-tool body.

3 . The anti-slip torque tool as claimed in claim 2 comprises:
a fastener-receiving hole;
the fastener-receiving hole traversing through the wrench torque-tool body, perpendicular to the pivot axis;
the fastener-receiving hole being positioned opposite the wrench handle, across the wrench torque-tool body; and
the fastener-receiving hole being oriented parallel to the specific sidewall.

4 . The anti-slip torque tool as claimed in claim 1 comprises:
at least one primary serration;
the at least one primary serration being positioned in between the at least one first groove and the first lateral edge of the specific sidewall;
the at least one primary serration being laterally integrated into the bracing surface of the specific sidewall; and
each within the at least one primary serration extending from the first base to the second base.

5 . The anti-slip torque tool as claimed in claim 1 comprises:
at least one secondary serration;
the at least one secondary serration being positioned adjacent to the first lateral edge of an opposing sidewall from the plurality of internal sidewalls;
the opposing sidewall being positioned parallel and opposite to the specific sidewall, across the wrench torque-tool body;
the at least one secondary serration being laterally integrated into the bracing surface of the opposing sidewall; and
each within the at least one secondary serration extending from the first base to the second base.

6 . The anti-slip torque tool as claimed in claim 1 comprises:
a first cavity;
the first cavity being positioned adjacent to the first lateral edge of the specific sidewall;
the first cavity traversing normal and into the bracing surface of the specific sidewall; and
the first cavity being extended from the first base to the second base.

7 . The anti-slip torque tool as claimed in claim 6 comprises:
at least one primary serration; and
the first cavity being positioned in between the first lateral edge of the specific sidewall and the at least one primary serration.

8 . The anti-slip torque tool as claimed in claim 1 comprises:
the third cavity comprising a convex portion and a concave portion;
the convex portion and the concave portion being adjacently connected to each other;
the concave portion being positioned adjacent to the first lateral edge of the opposing sidewall from the plurality of internal sidewalls; and
the convex portion being positioned adjacent to the bracing surface of the opposing sidewall.

9 . The anti-slip torque tool as claimed in claim 8 comprises:
at least one secondary serration; and
the at least one secondary serration being positioned within the convex portion of the third cavity.

10 . The anti-slip torque tool as claimed in claim 1 comprises:
an intermediate sidewall from the plurality of internal sidewalls being perpendicularly positioned in between the specific sidewall and an opposing sidewall from the plurality of internal sidewalls;
an entire cross-section of the intermediate sidewall being a partially-circular profile; and
the partially-circular profile being concave along a direction from the first lateral edge to the second lateral edge of the intermediate sidewall.

11 . The anti-slip torque tool as claimed in claim 1 comprises:
the plurality of internal sidewalls comprising an arbitrary sidewall and an adjacent sidewall; and
the arbitrary sidewall adjacently adjoining to the adjacent sidewall by a curved corner.

12 . The anti-slip torque tool as claimed in claim 1 comprises:
the plurality of internal sidewalls comprising an arbitrary sidewall and an adjacent sidewall; and
the arbitrary sidewall adjacently adjoining to the adjacent sidewall by an angled corner.

13 . The anti-slip torque tool as claimed in claim 1 comprises:
the at least one first groove and the at least one second groove each comprise a primary cavity and a secondary cavity;
the primary cavity and the secondary cavity traversing normal and into the bracing surface of the specific sidewall;
