Wrench

The innovation relates to a wrench with mouths, rings or provided at both ends of the handle Push-on key heads pivotable about transverse axes, in which the handle has longitudinal recesses on both sides.

In the known wrenches of this type, there are usually raised labeling fields in the middle of the handle arranged, the recesses that extend from these designation fields to the handle ends are flat and have a trough-shaped cross-section.

If the wrench handle is smeared with oil or grease, which is inevitable in many jobs it can slide easily in the hand that is holding it. This makes the precise placement of the wrench, in particular but it makes it more difficult to attach a wrench head that can be pivoted about a transverse axis onto a nut or screw head. The resulting loss of time is bothersome and disadvantageous.

The wrench according to the innovation offers due to the special design and arrangement of the longitudinal recesses in

his handle part holding the key and him by Applying or pushing on the leading hand ensures a secure hold, even if the handle is smeared.

A new wrench with both Handle ends provided mouths, rings or key heads pivotable about transverse axes, in which the handle is on has longitudinal recesses on both sides, is essentially characterized in that the handle on its one side two longitudinal recesses, separated by a central designation field, only extending up to the vicinity of the ends of the handle and on the other side has a continuous longitudinal recess.

It is expedient to let the longitudinal recesses run out continuously at their ends, at least approximating them to give a triangular cross-section and their ends in the manner of a boat front part, i.e. with a pointed arch contour, to train.

From the following description of a selected embodiment shown in the drawing, which is only for Explanation of the innovation serves, but is not intended to constitute a restriction, the advantages of the new wrench handle shape result.

In the drawing show:

Pig. 1 a supervision of a modernization Wrench that holds fork holders at both ends of its handle and in these Push-on key heads pivotable about transverse axes Has;

Figure 2 is a rear view of the key of Figure 1;

Fig. 3 is a section along the line III-III of Fig. 2;

FIG. 4 shows a section along the line IV-IV in FIG. 2.

The wrench 1 illustrated in FIGS. 1 to 4 has at one end of its handle, which is essentially rectangular in cross section, a fork 2 in which the transverse axis j5 of a double-sided wrench head 4 is mounted. At the other end of the handle is the fork 5, in which the transverse axis 6 carries the key head 7.

On the "front" of the handle shown in FIG a designation field 8 is arranged in the middle of the handle, which is a brand name or the name of the manufacturer can accommodate and - for example because of light polishing - can be slightly raised compared to the surface of the handle. At the ends of the handle are still in front of the hollow, rounded transitions to those that are wider than the handle thickness Fork arms smaller fields 9 and 10 to accommodate the wrench size numbers.

The recesses 11 and 12 are now between these small fields 9 or 10 and the central designation field 8 attached or pressed in when pressing the handle part.

The recesses 11 and 12 run out steplessly on both sides, they have a triangular cross-section (see. Fig. 4) and their outgoing ends are like the front of a boat,

i.e. with an upper pointed arch contour. In the relatively short recesses - which are also trough-shaped or could have a hollow cylindrical inner limitation - the pingers of the hand holding the key handle find a firm hold Hold, even with greasy hands or an oily key grip, even when the Handle in hand.

On the back of the handle is - as Fig. 2 shows only a continuous recess 15 arranged, which between the two small fields 9 'and 10' for recording the width across flats and expires at their ends in the same way as the recesses 9 and 10. This continuous Recess provides a safeguard against unwanted turning of the key handle in the hand, independently whether the hand holds the handle "long" or "short".

The triangular cross-section of the recesses can be a Obtained vertex angles of about 90 to 1 ^ 0 °, thereby yielding A sufficient depth and incline of the two side surfaces to securely hold the handle, if the upper side The width of the recess is at least 70 # the width of the handle is.

The stepless tapering of the recesses on both sides makes it easier to wipe out the recesses in order to or remove grease residues.
