The rotating detachable handle assembly (101) is generally made herein as a straight handle, having a rotating and detachably locking provisions for the ‘Tapered Degree Part (A)’, which helps the Part (A) to get effectively engaged within the corresponding cavity of the culinary vessel pocket (F) of the utensil.

The preferred embodiment of the rotating detachable handle assembly (101), as herein described and illustrated in the accompanying drawings, is preferably made as an assembly of five components (A), (B), (C), (D) and (E).

Part (A) is the main component of the handle assembly (101), which gets inserted and engaged within the cavity of pocket (F) of the utensil. Dimension and surface of said Part (A) is made slightly tapered from its distal end, at which the initial guide (i) is positioned, to the proximal end, where it is connected to other components of the handle assembly (101). The degree of tapering of the said tapered surface of the Part (A) is so chosen that on effective engagement of the Part (A) with the Pocket (F), said tapered surface of the Part (A) completely touches and matches the inner surface of the cavity within the culinary vessel pocket (F).

The tapered degree Part (A), in the handle assembly (101) is directly connected to the Gripping Part (C), particularly through the Fastener component (D) and its screwing mechanism involving Nut (E) therein. Above the Gripping Part (C), there is a Protective Part (B), which covers the Part (C) and also provides better hand holding grip for the user.

The Fastener (D) is preferably a metallic cylindrical rod like component having threads or knurling all over its cylindrical surface, wherein one end of the Fastener (D) is fixedly assembled with the proximal end of the Part (A). Another end of the screwable cylindrical rod component Part (D), involving the Nut (E), is provisioned to be screwably assembled at one side of the Gripping Part (C). Gripping Part (C) is provisioned with a threading pattern within its one end, which is in contact with the Part (A), wherein said threading pattern is corresponding to the threads or knurling on the said Part (D). The other side of the Gripping Part (C), opposite to its inwardly threaded end, has the Protective Part (B).

On the other hand, the culinary vessel pocket (F), fixed installed on the outer surface of the utensil, has a dimension matching with the overall shape and dimension of the tapered degree part (A), wherein the inner region or the cavity of the said Pocket (F) is so created that it matches with the outer surface and shape of the Part (A) of the said handle assembly (101). The culinary vessel pocket (F), is also provisioned with a slot or cavity corresponding to the shape and volume of the initial guide (i), positioned at the distal end of the Part (A). The inner region/cavity of the said pocket (F) also has tapered surface, which starts from the proximity of the utensil side towards the distal end of the said Pocket (F). Shape and dimension of the said Pocket (F) is so designed that it does not completely covers the total tapered surface area of the Part (A) and particularly covers only the upper half surface of the tapered degree part (A). Thus, the dimension of the said Pocket (F) allows the user to easily place the Part (A) of the said handle assembly (101) wherein firstly the initial guide (i) of the said Part (A) is places in the corresponding cavity of the said Pocket (F).

The Part A, the tapered degree part of the said handle assembly (101) is when inserted in the culinary vessel pocket (F), fixed installed on the outer surface of the utensil, particularly with the help of its ‘initial guide’ (i)and rotated there within to tighten the fastener mechanism with the help of part (D+E), the locking of part (A) and culinary vessel pocket (F) is established.

This locking of parts enables a safer usage of handle for handling the culinary vessels.

The fixed part (D) inside the gripping part (C) helps the combination of part (C+B+D) act as one assembly. This assembly is then attached to the combination of part (A+E) so an easy rotation of the assembly can be established.

As the rotation of the parts (B+C+D) is initiated the lateral movement of the assembly of part (A+E) occurs. This lateral movement helps to lock the tapered degrees of part (A) and static surface of part (F). During the lateral movement of Part (A) with respect occurred by the rotation of the fastener system help to lock the part (A) inside the static surface of part (F) by surface (2+3+4). The tapered degree locking occurred at the surfaces shown in the detailed view (3+4) helps the part (A) to provide a better grip on the static surface of part (F). The contact locking of surface shown in the detailed view (2) help to provide a better grip to the static surface of part (F) and the vertical surface of part (A).

Rotating and Detachably Locking Mechanism of the Handle assembly (101) with the culinary vessel pocket (F) of the utensil: Step I:-The user, holding the surface of Part (B) of the rotating detachable handle assembly (101), inserts the Part (A) of the said handle assembly (101) in the cavity of Pocket (F), fixed installed on the outer surface of the utensil.

Step II: -wherein The ‘initial guide’ (i) of said Part A gets accommodated within the corresponding cavity made within the inner most surface of the pocket (F) and thus the rest of the tapered surfaces of the Part (A) get positioned to be engaged with the inner surface of the said Pocket (F);

Step III:- Then the handle assembly (101) is rotated clockwise, so as the Fastener Part (D) gets screwably tightened within Part (C) and therefore the fastener mechanism involving the parts (D+E) initiated the lateral movement of the assembly of part (A+E) within the said pocket (F), supported with the said guide (i) and therefore pulls the Part (A) in forward direction.

Step IV:- Once the pull of tapered degree Part (A) within the pocket (F), actuated by rotational motion of the handle assembly (101), gets completed, locking of part (A) and culinary vessel pocket (F) is established.

It will be apparent to those skilled in the art that various modifications and variations can be made in the scheme(s), programming of various software based instructions involved, modules provisioned for data analysis and transmission/storage involved, or other possible arrangements and rearrangements within the present invention, without departing from the spirit or scope of the invention.
