Abstract
A vacuuming-off device includes at least one vacuuming-off unit that has at least one interface. The interface is mechanically and electrically connectable to a hand-held power tool, in particular to a hammer drill and/or chipping hammer, in at least one first application. The vacuuming-off device further includes an adapter unit that, in at least one second application, is connectable to the interface. The adapter unit has at least one connecting unit that is connectable to at least one energy supply.
Claims12
A vacuuming-off system, comprising:
- at least one vacuuming-off unit having an interface, the interface including a fastening element and an electrical contact point;
- and
- an adapter unit having at least one connecting unit configured to connect to at least one external energy supply, wherein:
- in a first configuration with the adapter unit removed, the fastening element mechanically connects the at least one vacuuming-off unit directly to a hand-held power tool and the electrical contact point electrically connects the at least one vacuuming-off unit directly to the hand-held power tool such that energy is supplied to the at least one vacuuming-off unit from the hand-held power tool in a first operating state,
- in a second configuration, the fastening element mechanically connects the at least one vacuuming-off unit directly to the adapter unit and the electrical contact point electrically connects the at least one vacuuming-off unit directly to the adapter unit such that energy is supplied to the at least one vacuuming-off unit from the external energy supply through the adapter unit in a second operating state,
- the adapter unit has at least one fastening, and
- in a third configuration with the adapter unit mechanically and electrically connected to the at least one vacuuming-off device such that energy is supplied to the at least one vacuuming-off unit from the external energy supply through the adapter unit in a third operating state, the at least one fastening mechanically connects the at least one vacuuming-off unit to a further hand-held power tool through the adapter unit.
4 more elements
An adapter unit for a vacuuming-off device, comprising:
- a single, contiguous body configured to removably directly electrically connect the adapter unit to an electrical contact point of a vacuuming-off unit interface and removably directly mechanically connect the adapter unit to a fastening element of the vacuuming-off unit interface, the vacuuming-off unit interface configured for removable mechanical and electrical connection to a hand-held power tool;
- at least one connecting unit configured to connect to at least one external energy supply so as to provide energy to the vacuuming-off unit in a first operational configuration;
- and
- at least one fastening configured to mechanically connect the adapter unit to a further hand-held power tool while the adapter unit is removably directly electrically connected to the electrical contact point of the vacuuming-off unit interface and removably directly mechanically connected to the fastening element of the vacuuming-off unit interface.
1 more element
A system, comprising:
- a first hand-held power tool;
- a further hand-held power tool configured differently from the first hand-held power tool;
- an external energy supply;
- a vacuuming-off device, including at least one vacuuming-off unit having at least one interface, the at least one interface including a fastening element and an electrical contact point;
- and
- an adapter unit having at least one connecting unit configured to connect to the external energy supply, wherein:
- in a first configuration with the adapter unit removed from the vacuuming-off device and the vacuuming-off device mechanically connected to the first hand-held power tool, the fastening element mechanically connects the vacuuming-off unit directly to the first hand-held power tool, the electrical contact point electrically connects the vacuuming-off unit directly to the first hand-held power tool, and the first hand-held power tool is mechanically connected with the external energy supply such that in a first operational state energy from the external energy supply is supplied to the vacuuming-off unit through the first hand-held power tool, and
- in a second configuration, with the vacuuming-off device mechanically connected to the further hand-held power tool, the fastening element mechanically connects the vacuuming-off unit directly to the adapter unit, the electrical contact point electrically connects the vacuuming-off unit directly to the adapter unit, and the adapter is mechanically and electrically connected to the external energy supply such that in a second operational state energy from the external energy supply is supplied to the vacuuming-off unit through the adapter unit.
