DESCRIPTION OF THE EXEMPLARY EMBODIMENTS

[0032] FIG. 1 shows part of a hand-held power tool 12a. The hand-held power tool 12a is designed as a chisel hammer, in particular as a demolition hammer. However, it is also conceivable for the hand-held power tool 12a to be in the form of a hammer drill, a rotary percussion hammer, or another hand-held power tool considered appropriate by a person skilled in the art. The hand-held power tool 12a is embodied as a portable hand-held power tool 12a, in particular a plug-in or battery-operated hand-held power tool. It is also conceivable that the hand-held power tool 12a is designed as a pneumatic hand-held power tool. The hand-held power tool 12a comprises at least one striking mechanism device 10a.

[0033] The striking mechanism device 10a is designed as a pneumatic striking mechanism, in particular as a wobble striking mechanism or as an eccentric striking mechanism. The striking mechanism device 10a preferably comprises at least one striker 16a. The striking mechanism device 10a preferably comprises a drive piston (not shown here), which is configured to drive the striker 16a. The pneumatic striking mechanism device 10a comprises at least one hammer tube 14a (cf. FIGS. 2 to 4) which is provided for guiding the striker 16a and/or the drive piston. A compression chamber of the striking mechanism device, in which an air cushion can be compressed during operation of the striking mechanism device designed as a pneumatic striking mechanism, is preferably arranged between the striker 16a and the drive piston. The drive piston can be driven, for example, via a wobble drive of the striking mechanism device 10a designed as a wobble striking mechanism, or via an eccentric drive of the striking mechanism device 10a designed as an eccentric striking mechanism. The drive piston and the striker 16a preferably have substantially the same maximum outer diameter. The hammer tube 14a is formed from sheet metal. The hammer tube 14a is designed to be seamlessly longitudinally slotted over at least a substantially entire longitudinal extension of the hammer tube 14a. The hammer tube 14a is formed of a single component that is entirely tubular in shape. The hammer tube 14a has a circular cross section over the entire longitudinal extension of the hammer tube 14a. The longitudinal extension, in particular the entire longitudinal extension, runs in parallel with a main axis of extension 48a of the hammer tube 14a.

[0034] The striking mechanism device 10a comprises at least one hammer tube guide element 28a, in which the hammer tube 14a can be arranged. At least in one operating state, the hammer tube 14a is arranged in the hammer tube guide element 28a (cf. FIG. 1 to 3). The hammer tube guide element 28a is tubular. The hammer tube guide element 28a has at least one circular internal cross section. A plurality of bearing ribs 52a is formed on an inner side 34a of the hammer tube guide element 28a, on which the hammer tube 14a rests in at least one operating state. The respective main axes of extension of the bearing ribs 52a run in parallel with a main axis of extension 54a of the hammer tube guide element 28a. The bearing ribs 52a extend over the entire longitudinal extension of the hammer tube guide element 28a. The longitudinal extension, in particular the entire longitudinal extension, of the hammer tube guide element 28a runs in parallel with the main axis of extension 54a of the hammer tube guide element 28a. The bearing ribs 52a are preferably distributed along a circumferential direction of the hammer tube guide element 28a which runs in a plane perpendicular to the main axis of extension 54 of the hammer tube guide element 28a. The bearing ribs 52a are designed to be interrupted in portions, at least as viewed along the respective main axes of extension of the bearing ribs 52a. However, it is also conceivable that the bearing ribs 52a, at least as viewed along the respective main axes of extension of the bearing ribs 52a, are designed without interruption. A maximum longitudinal extension of the hammer tube guide element 28a preferably corresponds to the maximum longitudinal extension of the hammer tube 14a. In at least one operating state, the hammer tube 14a is at least substantially completely surrounded by the hammer tube guide element 28a, as viewed at least radially. The hammer tube guide element 28a can be formed, for example, at least partially, preferably completely, from a light metal, in particular aluminum or the like, or from a plastics material. The hammer tube guide element 28a is fastened to a transmission housing 46a of the hand-held power tool 12a. It is also conceivable that the hammer tube guide element 28a is formed as a single piece together with the gear housing 46a of the hand-held power tool 12a.

[0035] The hammer tube 14a has a longitudinal slot 26a. The longitudinal slot 26a is formed in a lateral surface 50a of the hammer tube 14a. The longitudinal slot 26a extends in parallel with the main axis of extension 48a of the hammer tube 14a. However, it is also conceivable that the longitudinal slot 26a extends transversely, in particular at an angle of in particular less than 90°, preferably less than 45° and very particularly preferably less than 15°, to the main axis of extension 48a of the hammer tube 14a. The hammer tube 14a is rotationally symmetrical to the main axis of extension 48a of the hammer tube 14a. The hammer tube 14a has two free longitudinal edges 18a, 20a. The two free longitudinal edges 18a, 20a delimit the longitudinal slot 26a. The two free longitudinal edges 18a, 20a lie opposite each other, at least when viewed along a circumferential direction of the hammer tube 14a which extends in a plane perpendicular to the main axis of extension 48a of the hammer tube 14a. The two free longitudinal edges 18a, 20a are designed without teeth and/or have a straight profile along a portion that corresponds to at least 25% of a maximum longitudinal extension of the hammer tube 14a. The two free longitudinal edges 18a, 20a run in parallel with the main axis of extension 48a of the hammer tube 14a. However, it is also conceivable that the two free longitudinal edges 18a, 20a run transversely, in particular at an angle of in particular less than 90°, preferably less than 45° and very particularly preferably less than 15°, to the main axis of extension 48a of the hammer tube 14a. The longitudinal slot 26a is free of a weld seam, an adhesive seam, or the like, in particular over the entire longitudinal extension of the hammer tube 14a. A region between the two free longitudinal edges 18a, 20a, at least as viewed along the circumferential direction of the hammer tube 14a, is free of an adhesive seam, a welded seam, or the like, in particular over the entire longitudinal extension of the hammer tube 14a.

[0036] The two free longitudinal edges 18a, 20a contact each other without a material bond, at least in one operating state. The two free longitudinal edges 18a, 20a are at least in contact with each other when the hammer tube 14a is arranged in the hammer tube guide element 28a. The two free longitudinal edges 18a, 20a contact each other without a material bond over the entire longitudinal extension of the hammer tube 14a. A maximum outside diameter of the hammer tube 14a corresponds to a maximum inside diameter of the hammer tube guide element 28a. The maximum inside diameter of the hammer tube guide element 28a is particularly preferably smaller than the maximum outside diameter of the hammer tube 14a. Dimensions of the hammer tube 14a and/or the hammer tube guide element 28a, in particular the maximum inside diameter of the hammer tube guide element 28 and/or the maximum outside diameter of the hammer tube 14a, are selected in such a way that an arrangement of the hammer tube 14a in the hammer tube guide element 28a prevents out-of-roundness in the hammer tube 14a and a distance between the two free longitudinal edges 18a, 20a or the like can be corrected. The maximum inside diameter of the hammer tube guide element 28a is specified by the bearing ribs 52a of the hammer tube guide element 28a. By inserting the hammer tube 14a into the hammer tube guide element 28a, a movement of the two free longitudinal edges 18a, 20a can be produced, in particular until the two free longitudinal edges 18a, 20a contact each other.

[0037] Alternatively or additionally, it is conceivable that a cavity or a spacing is formed between the two free longitudinal edges 18a, 20a. A gap is formed between the two free longitudinal edges 18a, 20a. The two free longitudinal edges 18a, 20 are spaced apart from each other, viewed along the circumferential direction of the hammer tube 14a, in particular in such a way that end faces of the two free longitudinal edges 18a, 20a are not in contact. The cavity or the spacing is or can be formed between the two free longitudinal edges 18a, 20a, at least when the hammer tube 14a is not arranged in the hammer tube guide element 28a. It is also conceivable that a cavity or a spacing is formed between the two free longitudinal edges 18a, 20a when the hammer tube 14a is arranged in the hammer tube guide element 28a, in particular depending on a permissible tolerance range for a minimum inside diameter of the hammer tube 14a for guiding the striker 16a. The cavity or the spacing preferably extends along the entire longitudinal extension of the hammer tube. The two free longitudinal edges, viewed in the circumferential direction, preferably have a maximum spacing of in particular less than 1 mm, preferably less than 0.5 mm, particularly preferably less than 0.1 mm, and very particularly preferably less than 0.01 mm. The cavity or the spacing is in particular at least free of a weld seam, an adhesive seam, or the like.

[0038] The striking mechanism device 10a has at least one cover element 22a which, in particular in at least one operating state, contacts an outer surface 24a of the hammer tube 14a and overlaps the longitudinal slot 26a of the hammer tube 14a in such a way that a gap seal can be produced between the longitudinal slot 26a and the cover element 22a (cf. FIG. 3). The cover element 22 preferably overlaps the longitudinal slot 26a at least as viewed along the circumferential direction of the hammer tube 14a. The cover element 22a overlaps the longitudinal slot 26a over an entire longitudinal extension of the longitudinal slot 26a. The cover element 22a has at least one main axis of extension 56a, which runs in parallel with the main axis of extension 48a of the hammer tube 14a and/or with the main axis of extension 54a of the hammer tube guide element 28a at least in one operating state. The cover element 22a overlaps the longitudinal slot 26a when the hammer tube 14a is arranged in the hammer tube guide element 28a, in particular in an operating position. The cover element 22a is arranged between two bearing ribs 52a of the bearing ribs 52a, at least as viewed along the circumferential direction of the hammer tube guide element 28a, at least when the hammer tube 14a is arranged in the hammer tube guide element 28a. Along the circumferential direction of the hammer tube guide element 28a, at least one recess 32a is formed on the inner side 34a of the hammer tube guide element 28a, in which recess the cover element 22a is arranged. The recess 32a is delimited by at least two bearing ribs 52a of the bearing ribs 52a which are directly adjacent along the circumferential direction of the hammer tube guide element 28a. The cover element 22a is provided to seal the longitudinal slot 26a in a fluid-tight manner, in particular in an air-tight manner. The region, in particular the cavity or the spacing between the two free longitudinal edges 18a, 20a, is at least substantially, preferably completely, free of the cover element 22a. The cover element 22a is designed differently from the hammer tube 14a.

[0039] Alternatively, it is conceivable in at least one exemplary embodiment for the cover element 22a to be formed by the hammer tube 14a, wherein, for example, at least one free longitudinal edge 18a of the two free longitudinal edges 18a, 20a of the hammer tube 14a is folded back in such a manner, in particular in a Z or S shape, in particular at least when viewed along the circumferential direction of the hammer tube 14a, that a gap seal can be produced.

[0040] The hammer tube guide element 28a has at least one elongate elevation 30a which forms the cover element 22a. The elongate elevation 30a extends over the entire longitudinal extension of the hammer tube guide element 28a. The elongate elevation 30a preferably has a curvature, in particular as viewed along the circumferential direction of the hammer tube guide element 28a, which corresponds to a curvature of the hammer tube 14a, preferably the outer surface 24a of the hammer tube 14a, in particular as viewed along the circumferential direction of the hammer tube 14a, at least in a region of the longitudinal slot 26a. The elongate elevation 30a is arranged between two bearing ribs 52a of the bearing ribs 52a, at least as viewed along the circumferential direction of the hammer tube guide element 28a.

[0041] A plurality of positioning elements 40a is formed on the hammer tube 14a, which positioning elements are provided for axial positioning and/or for positioning in a circumferential direction of the hammer tube 14a relative to the hammer tube guide element 28a. It is also conceivable that only at least one positioning element 40a is formed on the hammer tube 14a. The positioning elements 40a are designed as outwardly directed tabs. The positioning elements 40a are distributed along the circumferential direction of the hammer tube 14a. The positioning elements 40a are formed on an axial end 58a of the hammer tube 14a. A further axial end 60a of the hammer tube 14a, which is arranged remote from the axial end 58a of the hammer tube 14a, is free of positioning elements. The positioning elements 40a are intended to interact with at least one positioning element 62a of the hammer tube guide element 28a for the purpose of axial positioning of the hammer tube 14a and/or for positioning in the circumferential direction of the hammer tube 14a relative to the hammer tube guide element 28a. A plurality of positioning elements 62a is formed on the hammer tube guide element 28a. The positioning elements 62a of the hammer tube guide element 28a are formed on an axial end 64a of the hammer tube guide element 28a. A further axial end of the hammer tube guide element 28a, which is arranged remote from the axial end 64a of the hammer tube guide element 28a, is free of positioning elements. The positioning elements 62a of the hammer tube guide element 28a are formed on the bearing ribs 52a, in particular on axial ends of the bearing ribs 52a. The positioning elements 62a of the hammer tube guide element 28a are designed as latching notches to which the positioning elements 40a of the hammer tube 14a form the counterpart. A movement of the hammer tube 14a along the circumferential direction of the hammer tube 14a relative to the hammer tube guide element 28a and/or an axial movement of the hammer tube 14a relative to the hammer tube guide element 28a is blocked in at least one direction by the interaction of the positioning elements 40a of the hammer tube 14a with the positioning elements 62a of the hammer tube guide element 28a.

[0042] The striking mechanism device 10a has at least one clamping element 42a, which is provided for axially clamping the hammer tube 14a with the hammer tube guide element 28a. The clamping element is designed, for example, as an elastic element, in particular as a piece of rubber, preferably as an O-ring.

The lateral surface 50f of the hammer tube 14f and the lateral surface 80f of the cover element 22f each have a plurality of ventilation openings 36f, 38f, which are in particular arranged in alignment with each other at least in one operating state.

[0053] At least in one operating state, the hammer tube 14f is at least substantially completely surrounded by the cover element 22f, in particular at least as viewed radially. In at least one operating state, the hammer tube 14f is arranged radially with respect to the cover element 22f. The maximum outside diameter of the hammer tube 14f corresponds to a maximum inside diameter of the cover element 22f. The maximum outside diameter of the cover element 22f corresponds to a maximum inside diameter of a hammer tube guide element (not shown here) 28f of the striking mechanism device 10f; the maximum inside diameter of the hammer tube guide element 28f is particularly preferably smaller than the maximum outside diameter of the cover element 22f. The cover element 22f is at least substantially identical to the hammer tube 14f except for a maximum inside and/or outside diameter and/or except for dimensions and/or a number of ventilation openings. Positioning elements 76f are formed on the cover element 22f, which positioning elements are provided for axial positioning and/or for positioning in a circumferential direction of the cover element 22f, which runs in a plane perpendicular to the main axis of extension 56f of the cover element 22f, relative to the hammer tube 14f. The positioning elements 76f are distributed along the circumferential direction of the cover element 22f. The plurality of positioning elements 76f are formed on an axial end 78f of the cover element 22f. A further axial end (not shown here) of the cover element 22f which is arranged remote from the axial end 78f of the cover element 22f, is designed without positioning elements. The positioning elements 76f of the cover element 22f are designed as outwardly directed tabs. It is also conceivable for the positioning elements 76f of the cover element 22f to be in the form of other positioning elements that appear sensible to a person skilled in the art. The positioning elements 76f of the cover element 22f are provided for interacting with positioning elements 40f of the hammer tube 14f for axial positioning and/or for positioning along the circumferential direction of the cover element 22f relative to the hammer tube 14f.
