The projections are pushed through a circular opening and spring back into their original position after being pushed through.

From the U.S. patent application US 2006/0070900 A1 Another case for holding tools or small parts is known. Tool holders can be attached to the inside of the cover or the base body in various positions.

From the U.S. patent US 6,279,744 B1 a tool case is known in which subdivisions of the volume of the tool case in the form of plates can be used at different positions in the base body.

From the Australian published application AU 2009243523 A1 a tool case is known, the interior of which can be equipped with containers of different sizes.

From the U.S. patent US 5,379,887 a tool case is known, which is provided on the inside of the lid with a receptacle for order forms. The holder is fixed in a fixed position on the inside of the cover.

With the invention, a case for holding tools or small parts is to be improved in terms of its flexibility.

According to the invention, a case for receiving tools or small parts is provided with the features of claim 1. Advantageous developments of the invention are mentioned in the subclaims.

A case according to the invention for holding tools or small parts has a base body, a cover pivotally hinged to the base body and a receptacle for documents and / or small parts fastened to an inside of the cover, the inside of the cover being provided with a plurality of first fastening devices which are designed to match the second fastening devices on the receptacle, the first and second fastening devices being designed and arranged such that the receptacle can be fixed in at least two different positions on the inside of the cover.

The inside of the lid can thus optionally be provided with a receptacle and the receptacle can be fixed in at least two different positions on the inside of the lid. This makes the interior of the case more flexible to use. If, for example, the accommodation of an electric tool in a certain area, for example the handle area, requires a particularly large amount of space in the case, the receptacle can be arranged such that it does not touch the handle of the electric tool when the lid is closed. Depending on what is to be stored in the case, for example an electric tool or small parts, the receptacle can thus be arranged in different positions or can be omitted entirely. The holder can be used, for example, for operating instructions, data sheets, but also small parts such as tools, USB sticks and the like.

In a further development of the invention, the first and second fastening devices are designed as latching devices.

In this way, the receptacle can be attached to the inside of the cover in a very simple manner, in particular without tools. Depending on the application for which the case is intended, the receptacle is then simply snapped into the desired position on the inside of the lid.

In a further development of the invention, the receptacle in the area of the second fastening devices each has at least one through opening, the at least one through opening allowing the fully latched state of the latching devices to be visually checked.

By being able to visually check the completely locked state of the locking devices, a very simple and quick checking possibility is given. Such a check, since it is done optically, can also be automated, for example, using cameras.

In a further development of the invention, the first fastening devices have undercut openings and the second fastening devices have projections with undercuts.

As a result, the receptacle can be locked in a very simple manner on the inside of the cover by inserting the undercuts of the projections into the undercuts of the openings.

In a further development of the invention, the openings have an insertion section and at least one elongated holding section starting from the insertion section, a width of the holding section being smaller than a width of the insertion section.

The projections with the undercuts are thus inserted into the insertion section of the openings and then pushed into the elongated holding section. A size of the openings is dimensioned such that the projections can be pushed in, the width of the holding section is dimensioned such that the projection can engage behind the holding section.

In a further development of the invention, two holding sections starting from the insertion section are provided, which enclose an angle of at least 90 ° between them.

In this way, two different latching positions can be achieved starting from the opening by using either a first holding section or a second holding section for inserting the projections with the undercuts.

In a further development of the invention, the second fastening devices have a peg extending from an underside of the receptacle and a latching projection arranged at the free end of the journal, which projects laterally beyond the journal, so that an undercut is formed between the latching projection and the underside of the receptacle.

A simple and reliable latching can be achieved by means of such a second fastening device.

In a further development of the invention, the receptacle has a through opening in the area of the latching projection, so that the latching projection is visible through the through opening when the receptacle is removed from the cover and is at least partially covered by the inside of the cover when the receptacle is correctly mounted on the cover.

Such a design enables the correct interlocking to be checked optically in a simple manner.

In a further development of the invention, the cover has at least one design protruding into the interior, the cover having a cover part arranged on the inside of the cover and at least partially surrounding the design, the cover part and the at least one design essentially having a flat inside of the cover form.

Such a cover part can be used to straighten the inside of the cover, which may not be flat. This allows, for example, small parts to be arranged in the case so that the inside of the lid closes the compartments for the small parts when the lid is closed, so that the small parts cannot fall around in the case. In addition, a substantially flat inside of the lid facilitates the arrangement of the receptacle in several different positions.

In a further development of the invention, the first fastening devices are provided on the cover part.

Since the cover part surrounds the indentation on the inside of the cover in sections and at the same time forms an essentially flat inside of the cover together with the indentation, the cover part can be arranged in areas at a distance from the wall of the cover. This means that there is enough space on the cover to accommodate one To form locking device with undercuts, for example a through opening with an insertion section and a holding section.

In a further development of the invention, the receptacle is designed as an injection molded plastic part. Training as a plastic injection molded part enables inexpensive production in large quantities. The second fastening devices can be produced in one piece with the receptacle, for example in the form of pins and locking projections arranged at the free end of the pins.

In a further development of the invention, the receptacle has a spring tongue resting against the inside of the cover.

By means of such a spring tongue, documents can be reliably held within the receptacle so that they do not fall out during transport and when the case is opened.

In a further development of the invention, the first fastening devices on the cover and the second fastening devices on the receptacle are arranged in the same grid.

An arrangement of the first and second fastening devices in one and the same grid enables in a very simple manner that the receptacle can be fastened in several different positions on the inside of the cover.

In a development of the invention, the distances between the first fastening devices on the cover and the distances between the second fastening devices on the receptacle are arranged in the same grid both in the longitudinal direction and in the transverse direction of the cover.

In this way it is possible not only to move the receptacle in one direction relative to the lid and then to fasten it again to the lid, but the receptacle can also be attached to the inside of the lid in two different positions rotated by 90 ° to one another.

In a further development of the invention, the second fastening devices are arranged on the receptacle at the corner points of an imaginary square, one side length of the square corresponding to a distance between the first fastening devices on the cover or a multiple of this distance.

This facilitates the arrangement of the receptacle in different positions rotated by 90 ° to one another.

The representation of the Fig. 1 shows a case 10 according to the invention with a base body 12 and a pivotally hinged to the base body 12 cover 14. On the inside of the cover 14, a receptacle 16 is provided, which is provided for inserting documents, for example operating instructions or data sheets. The receptacle 16 is designed as an injection molded part and is fastened to a cover part 18 on the inside of the cover 14. The cover part 18 has the shape of a passe-partout and surrounds an indentation 20 on the inside of the lid 14. The indentation 20 extends inwards when the lid of the case 10 is completely closed, see for example Fig. 8 . In the representation of the Fig. 1 The expression 20 thus extends upwards, in the direction of the viewer. Since the cover part 18 surrounds the shape 20, an essentially flat inside of the cover 14 is created.

The cover part 18 is provided with a total of eight first fastening devices 22, wherein in the illustration the Fig. 1 only three of the first fastening devices 22 can be completely recognized, the remaining first fastening devices are at least partially covered. The first fastening devices 22 are each provided as through openings for latching second fastening devices 24 onto the receptacle 16. The receptacle 24 is provided with a total of four second fastening devices, which in the illustration of the Fig. 1 but can only be recognized in sections. The second fastening devices 24 of the receptacle 16 are inserted into the openings of the first fastening devices 22, specifically into an essentially circular insertion section 26. Starting from the insertion section 26, the second fastening devices 24 are then linearly displaced in the direction of a slot-shaped holding section 28 or 30. Since the holding sections 28, 30 are each designed in the form of an elongated slot and are narrower than the insertion section 26, the second fastening devices 24 on the receptacle can engage behind the cover part 18 in the region of the holding sections 28 or 30 and thereby the receptacle 16 securely on the cover part 18 and thus lock on the inside of the cover 14.

It is already in the Fig. 1 It can be seen that the receptacle 16 can be displaced in the direction of the first holding section 28, starting from the insertion section 26, in order to latch onto the cover part 18 Fig. 1 so to the right. As an alternative to this, the receptacle 16 can also be displaced in the direction of the second holding section 30, in the illustration of FIG Fig. 1 so up. This alone makes different positions of the receptacle 16 possible on the cover part.

In addition, as already shown in the Fig. 1 can be seen, the cover part 16 not only in the in Fig. 1 position shown, but also in a compared to the position shown to the left shifted position on the inside of the lid 14 are attached. For this purpose, the second fastening sections 24 would only have to be in the in Fig. 1 the first fastening devices 22 shown on the far left on the cover part 18. The receptacle 16 is always arranged with all four second fastening devices 24 on the first fastening devices 22 arranged on the cover part 18 in a suitable manner and in the same grid as the second fastening devices 24.

The receptacle 16 is designed as an injection molded part and has a spring tongue 32 which, when the receptacle 16 is locked on the inside of the cover 14, bears against an inside of the cover. In the illustrated embodiment and when, as in Fig. 1 the receptacle 16 is empty, the spring tongue rests on the inside of the shape 20 of the cover 14. The spring tongue reliably holds documents inserted into the receptacle 16 in place.

The representation of the Fig. 2 shows a section of the representation of the Fig. 1 enlarged. The design of the first fastening devices 22 on the cover part 18 can be seen, each with a circular insertion section 26 and two elongated holding sections 28, 30 extending from the insertion section 26, the first holding section 28 and the second holding section 30 forming an angle of 90 ° to one another. On the first fastening device 22, which in Fig. 2 as the second from the left, part of the insertion opening 26 can still be seen. The rest of the insertion opening 26 and the two holding sections 28, 30 are covered by the receptacle 16. The second fastening device 24 of the receptacle 16 can also only be seen in sections. The second fastening devices 24 have two through openings 34, 36 which are separated from one another by a web and which together form approximately a circular shape. A peg extends from the web and extends into the first holding section 28. At the free end of the pin, a projection projecting in the radial direction is then arranged which engages behind the first holding section 28 and thereby locks the second fastening device 24 onto the first fastening device 22. The two through openings 34, 36 enable an optical control of the fully locked state. Because if the circular insertion opening 26 can still be seen through the through openings 34, 36, the fully latched state has not yet been reached. Only when the two through openings 34, 36 are covered by the sections of the cover part 18 which are adjacent to the first holding section 28 is the fully locked state achieved. It can be checked in a very simple manner whether the receptacle 16 is correctly locked on the cover part 18. Such a check can also be carried out automatically using cameras, for example.

The representation of the Fig. 3 shows a top view of the lid 14 of FIG Fig. 1 . In the representation of the Fig. 3 It can be seen that the first fastening devices 22 on the inside of the cover 14 or on the cover part 18 are arranged in the same grid as the second fastening devices 24 on the receptacle 16. Specifically, the distance in the transverse direction of the cover 14 is in Fig. 3 that is, from bottom to top, between the second fastening devices 24 on the receptacle 16 as large as twice the distance between two first fastening devices 22 on the inside of the cover 14, also seen in the transverse direction, that is to say in Fig. 3 from the bottom up. This allows the receptacle 16 not only in the in Fig. 3 to position shown on the cover 14, but also offset from the position shown by the distance between two first fastening devices 22 in the transverse direction, in Fig. 3 so shifted upwards.

Fig. 4 shows the lid 14 of the Fig. 3 also in a plan view, the receptacle 16 relative to the position of the Fig. 3 has been rotated 90 ° counterclockwise. This is possible because the distance between the first fastening devices 22 in the longitudinal direction of the cover 14, in 3 and 4 from right to left, corresponds to the distance between the second fastening devices 24. The second fastening devices 24 on the receptacle 16 are thus arranged at the four corners of an imaginary square. Starting from the in Fig. 4 position shown, the receptacle 16 can be seen still offset upwards by the distance between two first fastening devices 22 on the cover 14. In addition, the recording 16 in Fig. 4 can be arranged rotated by 90 ° or 180 ° on the inside of the cover 14.

As has been stated, a total of eight first fastening devices 22 are provided on the inside of the cover 14, the first fastening devices 22 being arranged in the same grid as the second fastening devices 24 on the receptacle. The second fastening devices 24 on the receptacle are also arranged at the corner points of an imaginary square, the side length of the square corresponding to twice the distance between two first fastening devices 22 on the inside of the cover 14. It is thereby possible to arrange the receptacle 16 in a total of six different positions on the inside of the cover 14. Specifically, these are the two in 3 and 4 represented positions as well as one in addition to the Fig. 3 Position rotated clockwise by 90 °. In addition, three additional positions are possible if the in Fig. 3 first fastening means 22 shown above can be used. Even when using these two upper first fastening devices 22 and then in FIG Fig. 3 respectively. Fig. 4 three second positions of the receptacle 16, which are each rotated through 90 ° to one another, are then possible as the second first fastening devices shown from below.

In the top view of the Fig. 3 and the Fig. 4 it can be clearly seen that the completely locked state of the first and second fastening devices 22, 24 can be checked optically from above. Because in the fully latched state shown, the two through openings 34, 36 are almost completely closed and the insertion section 26 is in turn covered by the receptacle 16.

As has already been explained, in addition to the six different positions described, six further positions of the receptacle 16 on the inside of the cover 14 can be realized by using not the first holding section 28 but the second holding section 30 for locking the respective second fastening devices 24 becomes.

With regard to the arrangement of the receptacle 16 on the inside of the lid 14, there is a great deal of flexibility and the receptacle 16 can be arranged in such a way that there is enough space for accommodating a wide variety of tools in the case 10.

The representation of the Fig. 5 shows a view of the section plane VV in Fig. 4 and the representation of the Fig. 6 shows the enlarged detail VI Fig. 5 . It can be seen that the cover part 18 is connected to the inside of the cover 14 only in sections. Specifically, the cover part 18 is connected to the cover 14 in the region of projections 38 on the inside thereof. In the area of these projections 38, the cover part 18 is ultrasonically welded to the cover 14. Both the cover 14 and the cover part 18 are made of plastic, which can be welded by means of ultrasound. The projections 38 can each have the shape of a ring or the shape of domes, for example. As shown, the shape of the projections 38 and the shape of the cover part 18 are selected such that tolerances in the manufacture of the cover 14 and the cover part 18 can be compensated for.

The representation of the Fig. 7 shows a top view of the case 10 with the lid 14 completely closed. The shape 20 in the lid 14, which can be seen in the illustration of FIG Fig. 7 downwards, i.e. into the image plane.

Fig. 8 shows a view of the section plane VIII-VIII in Fig. 7 . It can be seen that not only the in Fig. 8 the cover 14 located below has an indentation 20 projecting into the interior of the case 10, but also that in FIG Fig. 8 the underside of the base body 12 lying at the top has a corresponding configuration 20.

In the representation of the Fig. 8 The cover part 18 can be seen on the inside of the cover 14 and it can also be seen that the cover part 18 and the inner surface of the shape 20 provide a substantially flat inside of the cover 14. It can also be seen in Fig. 8 the receptacle 16 fastened to the inside of the cover 14.

The representation of the Fig. 9 shows the enlarged detail IX Fig. 8 . A section of the cover 14 and the cover part 18 placed on the inside of the cover can be seen. A section of the receptacle 16 and, in particular, the formation of one of the second fastening devices 22 on the receptacle 16 can also be seen Fastening devices 24 each have a pin 40 extending away from the receptacle, at the free end of which there is a projection 42 extending in the radial direction away from the pin 40. In the embodiment shown, the projection is in the form of a circular disk. An outer diameter of the projection 42 is slightly smaller than an inner diameter of the insertion section 26 of the first fastening devices 22 on the cover part 18, see Fig. 1 . In the in Fig. 9 In the position shown, the receptacle 16 has already been displaced relative to the cover part 18 in such a way that the pin has been inserted into the first holding section 28 or the second holding section 30 and as a result the projection 42 engages behind the cover part 18 by resting on the underside of the areas which are in contact adjoin the first holding section 28 or the second holding section 30.

The representation of the Fig. 11 shows one of the Fig. 7 corresponding view of the case 10 from above. The section planes XII-XII and XIII-XIII are in Fig. 11 but placed differently than the cutting planes VIII-VIII and XX in Fig. 7 .

Fig. 12 shows a view of the section plane XII-XII in Fig. 11 . The expression 20 in the cover 14, which is shown in the illustration of FIG Fig. 12 is arranged above. The cover part 18, which surrounds the shape 20 in the form of a passe-partout and which together with the inside of the shape 20 provides a substantially flat inside of the cover 14, can also be seen.

The representation of the Fig. 13 shows a view of the section plane XIII-XIII of the Fig. 11 . The receptacle 16, and in particular the spring tongue 32 of the receptacle 16, can be clearly seen, which, when no documents are inserted into the receptacle 16, lies against the inside of the cover 14.
