Embodiment Construction

[0026] exist figure 1 A cover device 10 and a power tool 12 are shown in an oblique view, wherein the cover device 10 has not yet been mounted on the power tool 12 . The power tool 12 is an angle grinder which generally has a first housing part 14 for receiving a motor (not shown) and a second housing part 16 which accommodates a bevel gear. A driven shaft 18 ( FIG. 2 ) extends from the bevel gear, which extends along an axis 19 and on which a grinding and cutting tool 20 is attached in the exemplary embodiment.

[0027] A protective cover 24 , which partially surrounds the grinding and cutting tool 20 , is attached to the second housing part 16 via a flange 22 .

[0028] as in figure 1 As can be seen in the figure, the cover device 10 is constructed in multiple parts and has a receiving part 26 as a central part. The receptacle 26 is designed in such a way that it can receive the protective hood 24 in a suitable manner. The receiving part has a rear wall 28 and is open on...

Abstract

The device (10) has a protective bonnet (24) i.e. angle grinder, comprising a receiving part (26) for receiving the protective bonnet. A closure part (30) is movably attached at the receiving part and movable between an open position and a closed position. The receiving part opens the closure part in an axial direction (19) over the protective bonnet of an electric power tool (12) relative to sharpening and/or separation tools (20) and is fastenable by closing//locking of the closure part at the protective bonnet.

Description

technical field [0001] The invention relates to a cover device with a dust suction device for use with an electric tool. Background technique [0002] The invention relates to a cover device for at least partially covering a grinding and / or cutting tool of an electric tool with a protective cover, in particular an angle grinder. Such cover devices are mounted separately from the protective cover. The invention also relates to a power tool having a protective hood and a cover mountable on the protective hood. [0003] EP 1 642 674 A1 discloses a cover device which has a counter part which delimits a receiving chamber for receiving a shielding element and a pivot part which is mounted pivotably about a pivot axis relative to the counter part. The pivoting part is formed by a suction connection, which has a connection device to which a suction line can be connected. [0004] This design has the disadvantage that the mounting of the cover element on the protective hood of the...
