DE202006004892U1 - Asymmetric handle for tool has support part forming even number of support services and grip part forming odd number of grip surfaces - Google Patents

Abstract

The asymmetric handle (1) includes a support part (20) and a grip part (30). The support part forms an even number of support surfaces (21), and the grip part forms an odd number of grip surfaces (31), or vice versa. The handle is suitable for a screwdriver. The form of the support surfaces may correspond to that of the thumb.

Description

technical area

The The invention relates to a single-ended handle that is asymmetrical supporting part and handle part.

State of technology

The handle of tool must prevent slipping when turning the workpiece. In order to increase the frictional force, a handle has been developed ( TW 251498 ), which is provided with pimples. However, these nubs can lead to pain of the user's hand. To prevent slippage, a square handle is also known ( TW 333117 ). However, this handle is not ergonomic.

Task of invention

Of the Invention is based on the object, a single-ended handle to create that fulfills the ergonomic condition.

These The object is achieved by the asymmetrical handle according to the invention solved, the one support part and a grip part, the support part even-numbered support surfaces and the handle part forms odd-numbered gripping surfaces. In use, the user wraps around with the palm of your hand and four fingers the handle surfaces and supports with your thumb against a suitable support surface, so that the rotation of the handle is relieved.

Ways to execute the invention

Like from the 1 to 5 can be seen, the invention consists essentially of a handle ( 1 ), such as handle of tool, which has a supporting part ( 20 ) and a handle part ( 30 ).

The support part ( 20 ) is located in the upper area of the handle ( 1 ) and serves to support the user's thumb. For this, the support part ( 20 ) even-numbered supporting surfaces ( 21 ). In the present embodiment, four support surfaces ( 21 ) provided uniformly on the outside of the support member ( 20 ) and correspond to the shape of the thumb.

The grip part ( 30 ) is located in the lower part of the handle ( 1 ) and adjacent to the support member ( 20 ) at. The grip part ( 30 ) corresponds to the shape of the palm and forms odd-numbered gripping surfaces ( 31 ). In the present embodiment, three gripping surfaces ( 31 ) provided uniformly on the outside of the handle part ( 30 ) are distributed. Due to the asymmetrical arrangement, the relative relationship between the support surfaces ( 21 ) and the gripping surfaces ( 31 ) differently. Therefore, in use, the user may choose a suitable support surface (depending on his hand size). 21 ) and grip surface ( 31 ) choose.

The asymmetrical supporting surfaces ( 21 ) and gripping surfaces ( 31 ) are not limited to this. This means that it is also possible to use odd-numbered support surfaces ( 21 ), like three, and even-numbered gripping surfaces ( 31 ), like four.

How out 6 can be seen, is the handle ( 1 ) at one end with a drive ( 40 ), which in the present example is a Phillips screw blade. When turning the workpiece, the user wraps around the grip surfaces with the palm of his hand and four fingers ( 31 ) and supports with its thumb against a suitable support surface ( 21 ). Therefore, the ergonomic condition is satisfied, so that the rotation of the handle is facilitated.

The The above description represents only a preferred embodiment of the invention and should not be used as a definition of boundaries and serve the scope of the invention. All equivalent changes and modifications are included to the scope of this invention.

by virtue of the above facts, the invention corresponds in its availability, Progressiveness and novelty fully on the requirements for a utility model.
