POWER TOOL SYSTEM AND METHOD FOR CONNECTING A VACUUMING DEVICE TO A POWER TOOL

Abstract

A power tool system and to a method for connecting a vacuuming device to a power tool. The system comprises a power tool having a tool, a vacuuming device for extracting dust that arises when working with the power tool, and a suction connection device, wherein the suction connection device is arranged between the tool of the power tool and the power tool and is connectable to the power tool in that a toothing of the power tool is able to be engaged with a mating toothing on the suction connection device. The present invention advantageously makes it possible for a suction hose that connects the vacuuming device and the suction connection device of the power tool system together to be able to be fixed relative to a handle of the power tool. Furthermore, an angle between the suction hose and the handle of the power tool can be set particularly easily.

Preferably, a toothing (5) can be integrated in the handle (7) of the power tool (1), said toothing (5) being able to cooperate with a mating toothing (6) on the suction connection device (4) (see FIG. 4 onward) such that an adjustable connection is formed between the power tool (1) and suction connection device (4). The toothing (5) of the handle (7) of the power tool (1) comprises a series of teeth, i.e. protruding elements or regions, which can pass into engagement with recessed regions or depressions of the mating toothing (6) of the suction connection device (4), with the result that the connection can be formed.

[0033] FIGS. 4 to 6 show preferred configurations of the suction connection device (4). In particular, FIG. 4 shows an oblique view of a preferred embodiment of a suction connection device (4). The suction connection device (4) can preferably be used for connecting the power tool (1) to its tool (3), for the one part, and for connecting the power tool (1) to a vacuuming device (2, illustrated solely schematically in FIG. 5), for the other part. Therefore, the suction connection device (4) preferably has three inputs or outputs, which are also referred to as connecting regions (8-10) according to the invention. According to the invention, it is preferred that the suction connection device (4) has a first connecting region (8) for connecting the suction connection device (4) to the tool (3) of the power tool (1). This first connecting region (8) is illustrated at the top right of FIG. 4. According to the invention, it is preferred that the first connecting region (8) and a second connecting region (9) are arranged along a central axis (11) within the suction connection device (4), wherein this central axis (11) may coincide preferably with the drive axis or drilling axis of the power tool (1). Preferably, the suction connection device (4) has a second connecting region (9) for connecting the suction connection device (4) to the power tool (1), wherein the power tool (1) may preferably also be configured as a core drill. Furthermore, the suction connection device (4) may have a third connecting region (10) for connecting the suction connection device (4) to a vacuuming device (2), wherein the vacuuming device (2) is preferably designed to extract the dust that accumulates during operation of the power tool (1) so as to prevent the dust from getting into the airways of a user.
