Abstract

A functional unit, in particular for a tool, a tool accessory and/or a lighting apparatus, that includes a housing, a suction region, which is arranged on the housing and with which the fastening apparatus can be fastened releasably to a substrate, and an electrically operated negative-pressure unit, which is arranged in the housing and to provide a negative pressure in the suction region. The fastening apparatus also includes at least one fastening interface for fastening the functional unit. Alternatively, or additionally, the fastening apparatus includes the functional unit. The functional unit includes a guide device, in particular a guide rail, a router guide, a routing template, a rolling guide rail, a drilling apparatus, a lamp and/or a grazing light.

First claim

The invention claimed is:

1. An arrangement comprising a fastening device and a function unit, the fastening device comprising:
a housing,
a suction region for releasably fastening the fastening device to an underlay, wherein the suction region is arranged on the outside of the housing, and
an electrically operated vacuum unit arranged in the housing, wherein the electrically operated vacuum unit is designed to provide a vacuum in the suction region, wherein
the fastening device further comprises at least one fastening interface for fastening the function unit,
wherein the function unit comprises a guide device comprising a guide structure defining a guide path.

2. The arrangement according to claim 1 , wherein the fastening interface is oriented in the same direction as the suction region, so that by way of one lay-on movement of the fastening unit onto the underlay, the suction region is able to be placed onto the underlay and, simultaneously, the fastening interface is able to be placed onto the function unit.

3. The arrangement according to claim 1 , wherein the fastening interface is designed to clamp the function unit between the fastening interface and the underlay, in a state in which the fastening device is fastened to the underlay.

4. The arrangement according to claim 1 , wherein the fastening device further comprises an energy store and/or an energy store interface, for attaching an energy store.

5. The arrangement according to claim 1 , wherein the fastening interface comprises a fastening mechanism, a slot nut, a toggle lever, an eccentric and/or a rotation lever.

6. The arrangement according to claim 1 , wherein the fastening device further comprises a sealing and/or lay-on arrangement, wherein the sealing and/or lay-on arrangement comprises a lay-on section and a sealing section running around the lay-on section.

7. The arrangement according to claim 6 , wherein the lay-on section and/or the sealing section is designed in an exchangeable manner.

8. The arrangement according to claim 6 , wherein the fastening device further comprises a suction side, wherein the suction region is provided on the suction side, and wherein the sealing and/or lay-on arrangement defines a lay-on plane for the laying on the underlay.

9. The arrangement according to claim 8 , wherein the lay-on plane is arranged at an angle with respect to the suction side.

10. The arrangement according to claim 6 , wherein the sealing and/or lay-on arrangement comprises a pressure sensor membrane.

11. The arrangement according to claim 1 , wherein the electrically operated vacuum unit is designed to provide two vacuum circuits.

12. The arrangement according to claim 11 , wherein the suction region comprises at least two separate suction sections, wherein each suction section belongs to a respective vacuum circuit.

13. The arrangement according to claim 1 , wherein the fastening device further comprises a venting valve for venting the suction region, and wherein the venting valve is coupled to an operating element.

14. The arrangement according to claim 1 , wherein the fastening device is designed to carry out a closed-loop control of the vacuum.

15. The arrangement according to claim 1 , wherein the fastening device is designed to detect an error state and to provide an error signal on the basis of the detected error state.

16. The arrangement according to claim 1 , wherein the fastening interface is a first fastening interface and the fastening device further comprises a second fastening interface.

17. The arrangement according to claim 16 , wherein the two fastening interfaces are arranged at different sides of the fastening device.

18. The arrangement according to claim 1 , wherein the fastening device comprises a plurality of suction regions.

19. The arrangement according to claim 18 , wherein the fastening device comprises a plurality of fastening units, wherein the fastening units are mechanically coupled to one another, and wherein each fastening unit provides one of the suction regions.

20. The arrangement according to claim 1 , further comprising a communication unit.

21. The arrangement according to claim 19 , wherein each fastening unit has an individual housing and/or an individual electrically operated vacuum unit.

22. The arrangement according to claim 1 , wherein the guide device comprises a guide rail, a router guide, a milling template and/or a roll guide rail.

23. A fastening device, comprising:
a housing,
a suction region for releasably fastening the fastening device to an underlay, wherein the suction region is arranged on the outside of the housing at the outside, and
an electrically operated vacuum unit which is arranged in the housing and which is designed to provide a vacuum in the suction region,
wherein the fastening device further comprises a function unit, and the function unit comprises a guide device comprising a guide structure defining a guide path and/or a drilling device.
