With the key according to the invention, iasfe@soad.er® can advantageously be designed in such a way that the contact surface is arranged at such a distance from the transverse edge of the head gile that the contact points between the contact surface and the circumference of the nut for nuts of different diameters in the longitudinal direction of the gchltissels staggered and adapted in their Irümimmg to the respective nut diameter *

In this context it has proven to be particularly advantageous to use the key according to the invention in this way to train that the support surface of the head part is so curved »that the Bertihrungsstellen in the case of nuts corresponding to different diameters, together with the transverse edge, each approximately approximately the same Include the angle of the mother's circumference · This is how it is designed The power transmission between wrench and nut for different diameters of the latter is the same advantageous.

A further development of the -.- key according to the invention, character- "*" is based on the fact that the guide strips of the head part of the contact point of the support surface for smaller nut diameter aur contact point for larger nut diameter are arranged with an acceptable mutual distance; ' In such an embodiment, the width of the channel-shaped support on the inside is corresponding to the generally different nut height. Stereo rails easily adapted to diameters. Further ditreii the arcuate configuration of the support surface is achieved that di © Berüiirüngsstelle _s iimaer is arranged in a region at the circumference in the Hutter the mutual spacing of the lateral Mihrungsleieten Mutternhöae the corresponding "

The key according to the invention can also be designed in a known manner as a striking tool with a hammer head, in particular made of a comparatively flexible material, for example hard rubber or UgI ₉₈ . The key is formed for this purpose Eweöonäßig such that an at least unilaterally open hat for receiving a Hammerkqfes comparatively elastic at the top of the head part '■ erkstoff disposed "This enables the hammer head to © asy manner be inserted laterally into its housing * without this would require a special deformation of the wrench head.

The receptacle for the hammer head is expediently designed as a Schwalbeneehwansnut, which can also have a parallel open lateral transverse hole on its bottom surface and thus a depression arranged transversely to the recess of the hammer head Provided approach ζ , which engages in the recess and a safeguard against lateral

Sliding claretelli, the hammer head can, for example, be fitted επ · 2efanäßig by vulcanizing into the groove »whereby the indentation engaging in the one« is easily formed by hot deformation with a suitable pressure. The removal of the hammer head after the wear and tear has occurred is not significantly "hindered" due to the flexibility of the material.

Further features and advantages of the invention will appear from the following description of a Ausföhrtangsbeispiels, äaa is shown in the drawing "Herein aeigt Pig * 1 is a side view of the © rfimduagegemäBen key with partial section of the Sehlüsaelkopfes, Figure * a look ύοά DE® key with Blickriöiitnag above, according to Pig * 1 , Fig. 3 shows a cross section along line 111 «.

The key according to Pig * 1 consists of a head part (9) with verlängertem- stem (7) as Handhab® "The inside ea & Xopfteils (9) is designed bogeiiartig .konkaT and is placed on the Uafasg'einer cap nut (16).

In the embodiment shown, the front end (10) of the head part (9) is designed like a sleeve with a passage opening (11) which forms a transverse edge (12) on the inside of the head part. When the key is in place, the transverse edge (12) engages in a hat (17) of the nut (16) occurs a "while the arc-shaped inner bearing surface of the head part in the region (1a.) with the periphery of lutam.t'ter (16) 'in touch occurs ₀ Due to the arcuate configuration of the support surface Nut of smaller Durohmessers approximately in the area (Ib) ₈ a nut of larger diameter in the area (1) of the support surface with the key in contact. The curved course of the contact surface (1 to 1b) is adapted to the respective curvature of the Muiternurafang, whereby concentrated surface pressure and damage to the nut body is termied * In addition, with the different diameter knives of the nut body there is a circumferential angle between the transverse edge (12) and the point of contact on the support surface of the key includes * which is suitable for power transmission between key and nut and prevents slipping in the circumferential direction

In order to avoid pressure on the circumference of the body, there is an extra layer of mm, for example in the case of softer material or sensitive surfaces

Pressure pad (3) is provided * which _{fits into a corresponding · = the longitudinal recess of the support surface (1, la?} 1b) and extends approximately over the entire length of the support surface. If necessary, an adhesive fastening of the cushion to the support surface can also be considered

The top of the head part (9) can, for example, pig. 2 with reinforcement ribs (15). In the middle area of the head part there is a dovetail groove (5) open transversely to the longitudinal direction of the key, which is formed by mutually inclined lobes (15) of the key body.
