[0031] FIGS. 1a, 1b, 2 and 3 show a first example of an add-on element 1. The add-on element 1 includes an attachment part 2 and an extension part 3. The attachment part 2 has a throughbore 4 and two threaded bores 5 with self-locking internal thread. It is understood that the threaded bores 5 are not necessarily required, when the dimensional accuracy of the structural parts is so good that an adjustment of a distance between the attachment part 2 and a perforated plate becomes unnecessary.

[0032] The extension part 3 has throughbores 6 arranged in a regular grid and is configured as a horizontal extension of the work area of a perforated plate.

[0033] The add-on element 1 has two struts 7 to stiffen the attachment part 2 and the extension part 3. Depending on the requirements for stiffness of the add-on element 1 and in dependence on the material of the add-on element 1, the need for struts 7 could also be dispensed with.

[0034] The use of the add-on element 1 on a perforated plate is explained in more detail with reference to FIGS. 4, 5a, 5b and 6. The attachment part 2 is mounted to the underside of a perforated plate 8, which has throughbores 9 arranged in a regular grid. For this purpose, a countersunk bolt 10 as connecting element passes through a respective throughbore 9 of the perforated plate 8 and the throughbore 4 of the attachment part 2.

[0035] A set screw 11 is screwed into each of the threaded bores 5 and pushes against the underside of the perforated plate 8. By adjusting the set screws 11, a variable adjustment of the distance between the attachment part 2 and the perforated plate 8 becomes possible in order to align the surfaces of the extension part 3 and the perforated plate 8 in relation to one another. It is understood that the set screws 11 are not necessarily required, when the dimensional accuracy of the components is so good that it is not necessary to adjust a distance between the attachment part 2 and a perforated plate.

[0036] As is readily apparent from FIG. 6, the extension part 3 forms a horizontal extension of the work area of the perforated plate 8.

[0037] FIGS. 7a, 7b, 8 and 9 show a second example of an add-on element 1. The add-on element 1 includes an attachment part 2 and an extension part 3. The attachment part 2 has two throughbores 4 and three threaded holes 5 with self-locking internal threads. It is understood that the threaded holes 5 are not necessarily required, when the dimensional accuracy of the components is so good that it is not necessary to set a distance between the attachment part 2 and a perforated plate.

[0038] The extension part 3 has throughbores 6 arranged in a regular grid and is designed as a horizontal extension of the work area of a perforated plate.

[0039] The add-on element 1 has a strut 7 to stiffen the attachment part 2 and extension part 3. Depending on the requirements with respect to stiffness of the add-on element 1 and in dependence on the material of the add-on element 1, the need for a strut 7 could also be dispensed with.

[0040] The use of the add-on element 1 on a perforated plate will be explained in more detail with reference to FIGS. 10, 11a, 11b and 12. The attachment part 2 is secured to the underside of a perforated plate 8, which has throughbores 9 arranged in a regular grid. For this purpose, countersunk bolts 10 as connecting element respectively pass through a throughbore 9 of the perforated plate 8 and a throughbore 4 of the attachment part 2.

[0041] A set screw 11 is screwed into each of the threaded holes 5 and pushes against the underside of the perforated plate 8. By adjusting the set screws 11. it is possible to variably adjust the distance between attachment part 2 and perforated plate 8 in order to align the surfaces of the extension part 3 and the perforated plate 8 in relation to one another. It is understood that the set screws 11 are not necessarily required, when the dimensional accuracy of the components is so good that it is not necessary to adjust a distance between the attachment part 2 and a perforated plate.

[0042] As is readily apparent from FIG. 12, the extension part 3 forms a horizontal extension of the work area of the perforated plate 8.

[0043] FIGS. 13a, 13b, 14a, 14b and 15 show a third example of an add-on element 1. The add-on element 1 includes an attachment part 2 and an extension part 3. The attachment part 2 has a throughbore 4 and two threaded holes 5 with self-locking internal thread. It is understood that the threaded holes 5 are not necessarily required, when the dimensional accuracy of the components is so good that it is not necessary to adjust a distance between the attachment part 2 and a perforated plate.

[0044] The extension part 3 has throughbores 6 arranged in a regular grid and is designed as a work area that is vertical to the work area of a perforated plate.

[0045] The add-on element 1 has two struts 7 to stiffen the attachment part 2 and the extension part 3, Depending on the requirements for stiffness of the add-on element 1 and in dependence on the material of the add-on element 1, the need for struts 7 could also be dispensed with.

[0046] The use of the add-on element 1 on a perforated plate is explained in more detail with reference to FIGS. 16, 17, 17b and 18. The attachment part 2 is secured to the underside of a perforated plate 8, which has throughbores 9 arranged in a regular grid. For this purpose, a countersunk bolt 10 as connecting element passes through a respective throughbore 9 of the perforated plate 8 and the throughbore 4 of the attachment part 2.

[0047] A set screw 11 is screwed into each of the threaded holes 5 and pushes against the underside of the perforated plate 8. By adjusting the set screws 11, it is possible to variably adjust the distance between the attachment part 2 and the perforated plate 8 in order to align the surfaces of the extension part 3 and the perforated plate 8 in relation to one another. It is understood that the set screws 11 are not necessarily required, when the dimensional accuracy of the components is so good that it is not necessary to adjust a distance between the attachment part 2 and a perforated plate.

[0048] As is readily apparent from FIG. 18, the extension part 3 forms a work area that is vertical to the work area of the perforated plate 8. The extension part 3 thus forms an angle located on one side of the perforated plate 8, without restricting the work area of the perforated plate 8.
