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 a first pair of grooves and a second pair of grooves, 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 pair of grooves and the second pair of grooves 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.

Claims (37)

1. An anti-slip wrench-type tool comprising:

a wrench torque-tool body;

at least one engagement element;

the wrench torque-tool body comprising a plurality of internal sidewalls, a first base and a second base;

the plurality of internal sidewalls comprising an arbitrary sidewall and an adjacent sidewall;

the arbitrary sidewall adjacently adjoining to the adjacent sidewall by a curved corner;

each of the plurality of internal sidewalls comprising a first lateral edge, a second lateral edge and a bracing surface;

the engagement element comprising a pair of first grooves and a pair of second grooves;

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 internal sidewall from the plurality of internal sidewalls;

the pair of first grooves and the pair of second grooves being positioned offset from each other along the bracing surface of the specific internal sidewall;

the pair of first grooves and the pair of second grooves each comprising a primary cavity and a secondary cavity, the primary cavity and the secondary cavity traversing into the wrench torque-tool body from the first base to the second base, the primary cavity and the secondary cavity traversing normal and into the bracing surface of the specific internal sidewall, the primary cavity and the secondary cavity intersecting each other at an intersection point, the intersection point being not collinear with the bracing surface of the specific internal sidewall, a depth of the secondary cavity being greater than a depth of the primary cavity; and

the primary cavity from the pair of first grooves being positioned adjacent to the primary cavity from the pair of second grooves.

2. The anti-slip wrench-type tool as claimed in claim 1 comprising:

an attachment body;

an engagement bore;

the attachment body being centrally positioned around and along the pivot axis;

the attachment body being connected adjacent to second base; and

the engagement bore traversing into the attachment body along the pivot axis, opposite the wrench torque-tool body.

3. The anti-slip wrench-type tool as claimed in claim 1 comprising:

an attachment body;

the attachment body being centrally positioned around and along the pivot axis; and

the attachment body being adjacently connected to the second base.

4. The anti-slip wrench-type tool as claimed in claim 1 comprising:

an entire cross-section for each of the plurality of internal sidewalls being a partially-circular profile; and

the partially-circular profile being convex along a direction from the first lateral edge to the second lateral edge.

5. The anti-slip wrench-type tool as claimed in claim 1 comprising:

an entire cross-section of the primary cavity 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.

6. The anti-slip wrench-type tool as claimed in claim 1 comprising:

an entire cross-section of the secondary cavity 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.

7. The anti-slip wrench-type tool as claimed in claim 1 , wherein the engagement element being centrally positioned in between the first lateral edge and the second lateral edge of the specific internal sidewall.

8. The anti-slip wrench-type tool as claimed in claim 1 comprising:

the at least one engagement element being a plurality of engagement elements;

the plurality of engagement elements being radially distributed about the pivot axis; and

each of the plurality of engagement elements being laterally integrated into a corresponding internal sidewall from the plurality of internal sidewalls.
