Abstract

A hex key comprising an actuating end (10) formed in a shaft shape and provided with an actuating end face (11) and six equally divided support surfaces (12), wherein at least one of the support surfaces (12) is formed an incision (121) one arranged on the support surface (12) and connected edge angle (θ) is arranged, wherein the at least one incision (121) through the actuating end face (11) passes therethrough.

Description

Technical area

The The invention relates to a hand tool, in particular a hex key.

State of the art

To the Use of a conventional Allen key becomes its end of operation inserted into the receptacle of a hexagon screw, wherein the actuating end of the hexagon wrench is rotated and thereby a force on the inner wall of the recording the hexagon screw exerts; after a long time Time, said inner wall will wear out by frequent turning of the hex key, so that the end of the operation no longer reliable Press against the inner wall of the receptacle and can exert a force on it. As a result, the operating end slips light, so that the user can not efficiently exert a force.

Object of the invention

Of the Invention is based on the object to a hex key create, at the support surfaces incisions are formed, wherein the edge angle in the most verschwandsten inner walls of the Engage recording so that the operating end reliably against Press the inner wall of the receptacle and exercise a force on it can, causing the end of the operation not slip easily, making an efficient exercise force achievable is.

Technical solution

These The object is achieved by a Allen key solved with the features of claim 1. Advantageous embodiments are Subject of the dependent Claims.

Of the Hexagonal key according to the invention comprises an end of operation, the shaft-shaped formed and with an actuating end face and six equally divided support surfaces is provided, wherein at least one of the support surfaces an incision is formed, which at a bordering on the support surface and connected edge angle is arranged, wherein the at least one cut through the actuating end face passes through.

At the hexagon key according to the invention three beabestandet arranged by the said support surfaces respectively two cuts on.

At the hex key according to the invention has each of the support surfaces one Incision on, with the incisions on the same side of each corresponding support surface are located.

At the hexagon key according to the invention two opposite ones of the six support surfaces respectively an incision, with the incisions on the same side the respective corresponding support surface.

Of the hexagonal key according to the invention advantageous insofar as formed on the support surfaces incisions are, with the edge angle in the most verschwandissten inner walls engage the recording, so that the operating end reliably against Press the inner wall of the receptacle and exercise a force on it can, causing the end of the operation not slip easily, making an efficient exercise force achievable is.

Ways of executing the invention

in the Following are the tasks, features and benefits of the present Invention with reference to the detailed description of the embodiments and the attached Drawings closer be explained. However, the invention should not be limited to the description and the accompanying drawings limited become.

According to the first preferred embodiment of 1 to 3 is the invention formed according to Allen key L-shaped and includes an actuating end 10 ,

How out 1 . 3 and 4 As can be seen, the end of the operation is 10 shank-shaped and inserted into a receptacle A1 of a hexagon socket A screw. The end of the operation 10 is with an actuating end face 11 and six equally divided support surfaces 12 Mistake; the actuating front 11 is a plane, and on at least one of the support surfaces 12 is an incision 121 formed on one of the support surface 12 adjacent and connected edge angle θ is arranged, wherein the at least one incision 121 is elongated and parallel to the axis of the actuating end 10 runs, wherein the at least one incision 121 through the actuating face 11 passes through; preferably all have cuts 121 a triangular cross section.

According to the first preferred embodiment, six cuts 121 of which three are beaerbet arranged and two incisions 121 have, so that the operating end 10 can engage in the inner peripheral wall of the receptacle A1 when turning both clockwise and counterclockwise.

Continue on 4 directed. The end of the operation 10 is inserted into the receptacle A1 of a hexagon socket screw A, wherein the edge angle θ in the inner wall of the receptacle A1 so engages that the actuating end 10 can reliably press against the inner wall of the receptacle A1 and thereby does not slip easily, whereby an efficient exercise of force can be achieved.

According to the second preferred embodiment of 5 are six cuts 121 provided, the six support surfaces 12 one incision each 121 have, with the incisions 121 on the same side of the corresponding support surface 12 are located. That means the cuts 121 According to the second preferred embodiment are in the same direction of rotation, from the actuating end 11 considered to run counterclockwise.

According to the third preferred embodiment of 6 are two cuts 121 provided, with two opposite of the six support surfaces 12 one incision each 121 have, with the incisions 121 on the same side of the corresponding support surface 12 are located.

According to the fourth preferred embodiment 7 is an incision 121 intended.

In the hexagonal wrench according to the invention, it is crucial that the edge angle θ can engage in the most wear-resistant inner wall of the receptacle, the number and the arrangement manner of the incisions 121 are not limited in the present invention.

The The above description represents only the preferred embodiments of the invention and is not intended to limit the claims. All equivalent changes and modifications made in the spirit of the claims will belong to the scope of the present invention.
