Socket wrench kit.

In automobile construction, for example, it corresponds to the rule that for the screw connections implemented on a motor vehicle no uniformly shaped and uniformly sized screws and nuts are used. To tighten and loosen the same must therefore, keys are provided that correspond to the respective screw or nut connection in the size and shape of the one in question Have connecting end of a group of screws or nuts, in this context adjustable wrench designs, like adjustable wrenches, English or French,

should remain sighted.

This is why they are used in most motor vehicle workshops today the fitters with a large number of socket wrenches assembled into a kit, all of which are shaft-shaped Have handle part which has a curved end portion at least at one end and in a plug end polygonal cross-section ends. The mating end corresponds to the most frequently used screws and nuts The individual keys are designed as triangles, squares and hexagons, in order to fit into the appropriately designed To fit the indentations of the head of the individual screws, while with other wrenches the plug end as polygonal shaped blind hole is designed to be attached to nuts of appropriate shape can. Such Socket wrench kits can also include keys in which the cross-section of the respective plug end overlaps the entire key length continues. The shaft-shaped handle part thus has, for example, a continuous hexagonal one Cross-section, so that both ends form a respective plug-in end for cylinder screws with hexagon socket.

Such socket wrench kits consisting of a large number of individual keys are for use in workshops Ideally suited, especially because the shaft length of the handle part is taken into account for every key the forces required to tighten and loosen the respective group of screws or nuts to achieve an advantageous lever arm can be optimally selected. The accommodation of such a mortise wrench kit in a toolbox is not possible due to lack of space, which is why all automobile manufacturers today For reasons of cost, content with only one mostly as

Double key trained socket wrench as an associated Supplied with tools that one or two of the most important groups of nuts or bolts can handle can be.

The invention is based on the intended purpose, a In particular, a socket wrench kit suitable as an accessory for the tool box of a motor vehicle is available with which a large variety of different screws or nuts can be handled. The object of the invention is to provide one of these ideas to create corresponding socket wrench kit that can be accommodated in a space-saving manner.

According to the invention, this object is achieved by a shaft-shaped handle part, at least at its one End ends in a male end with a polygonal cross-section, and an exchange kit consisting of several push-on parts, in which each individual plug-on part at one end of its defined plug-in axis is attached to the plug-in end of the handle part adapted plug connection and at the other end of the axle a different to the other push-on parts Has screw or nut connection.

In the case of the socket wrench kit according to the invention the plug end of the handle part, for example, as a square formed, which is arranged at the end of a curved end portion and on which the individual slip-on parts can be attached via a square blind hole. The single ones Push-on parts differ from one another in terms of their differently sized and shaped screw and nut connections, so that a screw connection for example in the

509826/0278

Shape of a triangle and "with another one a connection is in the shape of a hexagon, which is shown in this cross-sectional shape "different for other push-on parts Have sizes. Since such slip-on parts have a relatively small size, it is possible to use the entire Carry out the kit to save space, the size being mainly determined by the size of the shaft-shaped Handle part and still only due to the number of, in contrast, very small slip-on parts that are in one Toolbox can experience an arrangement that also takes into account the shape of the handle part. Since in Compared to the known kits of spring socket wrenches, practically only the plug end remains the kit according to the invention can be manufactured and offered much cheaper because of the considerable material costs omitted, which arise in the known kits through the handle part of the individual socket wrench.

Further advantageous and expedient developments of the invention are covered in the related claims.

An embodiment of the invention is shown schematically in the drawing and is explained in more detail below. It shows:

Figures 1 and 2 the shaft-shaped handle part of the socket wrench kit according to the invention,

Figures 3 through 6 have four different clip-on parts, respectively in a side view and in the two front views, and

Figures 7 to 10 in a respective cross-sectional view these four slip-on parts in the attached state on the handle part according to FIGS. 1 and 2.

S09826 / 0278 _ ₅ _

The shaft-shaped handle part 1 of the socket wrench kit according to the invention consists of a round steel 2, the end sections 3 and 4, which are essentially bent at right angles which end in a respective plug end 5 and 6. These Plug-in ends each have the shape of a square, whereby it is preferably provided that one square has a larger one Cross-section than the other. Alternatively, it can also be provided that at one end of the handle part, for example a square is formed as a plug end, while a hexagon is formed at the other end. One plug end 6 of the handle part is one for attaching each one larger variety of slip-on parts provided that a Form exchange set. For this purpose, the individual push-on parts 7> 8, 9 and have their defined plug-in axis at one end a blind hole 17, 18, 19 and 20, the cross-sectional size of which is adapted to that of the square 6. At the other The individual slip-on parts have different ends of the thru-axle large or differently shaped plug connections, namely either a square 11 in the Push-on part 7 and a square 12 in the push-on part 8, which are of different sizes and which also differ in size of the square 5 and the square 6, a hexagon 13 in the slip-on part 9 and a larger hexagon with the push-on part 10. While the push-on part 10 has the overall shape of its hexagonal plug connection, the other three push-on parts 7 »8 and 9 each have one cylindrical main body 14, 15 and 16, in one end face the square blind holes 17 »18 and 19 let in and the other end face of the square connections 11 and 12 or the hexagonal connection 13 protrudes will. Instead of the full cross-section, these connections 11, 12 and 13 can be used for further push-on parts can also be made hollow so that it can be fitted with such other push-on parts is also possible to fiddle with nuts by using them

by means of their recess on the respective nut _{to be tightened or loosened y} as well as the slip-on parts shown in the drawing are inserted via the appropriate connection 11, 12 or 13 in the corresponding recess of a screw to be tightened or loosened.
