Alternatively or additionally, there is the possibility of arranging different tool units, for example, so that different types of activities can be performed with the tool device, as will be discussed below.
[0004] EP 1 479 284 A1 describes a lawnmower with an electric motor operated by a battery.
[0005] Further embodiments of handheld power tools are described in EP 1 424 002 A1, JP 2008-173047 A and JP 2014-27911 A. Summary of the invention
[0006] The object of the present invention is to provide a tool device of the type mentioned at the outset which has increased operational safety.
[0007] This object is achieved according to the invention in a tool device of the same type in that the tool device comprises a blocking element which can be transferred from a blocking position, in which the tool unit is fixed in the tool holder to prevent it from being removed, to a release position, in which the tool unit can be removed from the tool holder, and vice versa, wherein the blocking element can be transferred to the release position for releasing the tool holder in order to remove the tool unit only after the battery has been removed from the battery holder.
[0008] A blocking element is provided in the tool device according to the present invention. The blocking element can occupy a blocking position. In the blocking position, the tool unit arranged in the tool receiving portion is fixed and cannot be removed from the tool receiving portion. In order to remove the tool unit, the blocking element must first be transferred to the release position. According to the present invention, it is provided that the blocking element can only occupy the release position when the battery is removed from the battery receiving portion. Removing the battery ensures that the drive device is not electrically loaded, so that at least one tool cannot be started. As a result, when the tool unit is removed from the tool receiving portion, the user can be prevented from causing accidental movement of the tool. This reduces the risk of injury to the user. Compared with tool devices according to the category, the operational safety of the tool device is improved.
[0009] It will be appreciated that the battery may preferably be designed to be rechargeable.
[0010] In a preferred embodiment of the tool device according to the invention, it is provided that the blocking element and the battery include or are configured with corresponding contact elements, which contact each other in the inserted state of the battery and in the blocking position of the blocking element, and the blocking element cannot be transferred from the blocking position to the release position as long as the battery is in the inserted state in the battery receptacle. It is particularly provided that the blocking element cannot even move only when the battery is in the inserted state, because the contact elements of the blocking element and the battery cooperate in such a way that the blocking element cannot or substantially cannot move. The blocking element can only be transferred from the blocking position to the release position when the battery is in the removed state.
[0011] In another advantageous embodiment of the tool device according to the invention, the blocking element and the battery include or are configured with corresponding abutment elements, which, when the battery is in the inserted state, will abut against each other and prevent further movement of the blocking element when the blocking element is transferred from the blocking position in the direction of the release position, wherein the tool holder is partially released, but the tool unit cannot be removed from the tool holder. In such an embodiment, there is the possibility of moving the blocking element in the direction of the release position. As a result, the tool holder is partially released. However, the tool unit cannot still be removed from the tool holder and is still prevented from being removed by the blocking element. The blocking element and the corresponding abutment elements of the battery cooperate with each other and, after the movement of the blocking element, they abut against each other as long as the battery is still in the inserted state. Only after the battery is removed can the blocking element be moved further to the release position in order to remove the tool unit.
[0012] In the last-mentioned advantageous embodiment, for example, there may be the possibility of access to the tool unit arranged in the tool receptacle.

[0029] Advantageously, at least one tool unit comprises at least one eccentric element coupled to at least one tool, which is coupled directly or indirectly to a rotating drive element of the drive device arranged in the tool receptacle. The at least one eccentric element can be operatively connected to the drive element and thereby preferably rotate about an axis different from the axis of the drive element. Thus, the at least one tool can perform a reciprocating motion.
[0030] Advantageously, the tool device comprises a first locking element which is arranged on the blocking element and cooperates with a corresponding second locking element which is arranged on the tool receptacle in order to fix the blocking element in the blocking position on the housing. The locking element can be used to ensure that the blocking element cannot be accidentally transferred from the blocking position to the release position.
[0031] Advantageously, the second locking element is held on the tool receptacle in a positionally fixed manner. This facilitates the handling of the tool device for locking the blocking element.
[0032] The locking element can be in a force-locking and / or form-locking state in the inserted state. For example, form-locking, clamping connection, locking connection, etc. are conceivable.
[0033] It can be provided that the tool unit is acted upon by means of the first locking element, with the force being directed in the direction of the tool receptacle, so that the tool unit can be held in a fixed position in the tool receptacle by means of the locking element.
[0034] Advantageously, the first locking element is fastened to the blocking element and is preferably held captively on the blocking element.
[0035] In order to simplify the installation and removal of the tool device, it is advantageous if the first locking element can be actuated manually and without tools for locking with the second locking element and for unlocking the second locking element.
[0036] In a preferred embodiment of the tool device according to the invention, the first locking element comprises a rotary knob or is designed as such a rotary knob.
[0037] For example, it can be provided that a recess is formed on the first locking element, into which the second locking element is introduced, wherein at least one engaging strip and groove are arranged on the recess and on the second locking element. Advantageously, when the blocking element is transferred into the blocking position, the second locking element is introduced into the recess. For example, at least one strip is arranged on the recess, which can be embedded in the groove on the second locking element. Or vice versa. As described above, when the knob is provided, the recess can be shaped, for example, in sections in an arcuate manner, so that the second locking element can be fixed to the first locking element by turning the knob.
[0038] Advantageously, the tool unit engages with the second locking element, thereby ensuring the positioning of the tool unit in the tool receptacle.
[0039] Advantageously, a through-opening is provided which is formed on the tool unit and through which the second locking element penetrates.
[0040] Advantageously, the tool device comprises an orientation element which is arranged at a distance from the second locking element, is held in an orientation-fixed manner on the tool receptacle and engages with the tool unit. This allows the positioning of the tool unit in the tool receptacle to be ensured.
[0041] For example, a through-opening is provided which is formed on the tool unit and through which the orientation element is passed or into which the orientation element is inserted.
[0042] Advantageously, the tool unit engages with the second locking element and the orientation element.
[0043] The second locking element and the orientation element are advantageously designed as bolts.
[0044] The tool device preferably comprises a plurality of tool units which comprise tools which differ from one another in terms of their type, their purpose and / or size.

[0064] Two advantageous embodiments of the tool device according to the invention are described below. The same reference numerals are used for the same or identical features and components. First, the following will discuss Figures 1 to 4 The tool equipment shown in the figure is then explained Figures 5 to 7 Further advantageous embodiments of the invention are shown in part or in full in FIG. Here, only the embodiments according to Figures 1 to 4 The same advantages can be achieved using both embodiments.
[0065] Figure 8 and 9 A partial view of a section of a tool unit and a drive mechanism for the tool unit is shown, which can be used in both embodiments of the invention. The same applies to Fig.10 and 11 Therefore, refer to Figures 8 to 11 The explanation applies to both embodiments.
[0066] according to Figures 1 to 4 The tool device according to the invention is designated as a whole by reference numeral 10. It is designed as an electric hedge trimmer and comprises a tool unit 12 having two counter-acting tools 14, as described below, which are cutting tools, also referred to as knives 16, for separating small branches and the like. The tool unit 12 is Figures 1 to 4 Only partially shown. Figure 6 and 7 The tool unit 12 is shown in its entirety.
[0067] The tool device 10 further comprises a housing 18. The housing 18 has two housing half shells 20, 22 joined to one another. The housing 18 has an upper side 24 and an underside 26 as well as a rear side 28 and a front side 30.
[0068] In the present case, the position and orientation indications are to be considered in relation to the intended use of the tool device 10. When used as intended, the user grips the tool device 10, in particular from the rear, so that the rear side 28 faces the user. The tool unit 12 protrudes from the front side 30. The upper side 24 faces the user, while the lower side 26 points away from the user.
[0069] A handle device 32 is provided, which is formed by a recess on the housing 18. An actuating element 34 for activating the tool device 10 is arranged on the handle device 32. Furthermore, a further curved handle device 36 is provided, which serves to guide the tool device 10.
[0070] The housing 18 has a receiving space formed between the housing half shells 20, 22. A drive device 38 for driving the tool 14 is received in the receiving space. The drive device 38 comprises, in particular, an electric motor 40 ( Figure 8 ).
[0071] The electric motor 40 drives a drive element 42 which is in the present case pin-shaped and designed as a polygon with a non-circular cross section. The drive element 42 defines an axis 44 .
[0072] To supply the drive device 38 with electrical energy, the power tool 10 has a battery 46 , which in the present case is rechargeable. A battery receptacle 48 is provided for the battery 46 on the housing 18 on the bottom side 26 adjacent to the rear side 28 .
[0073] For example, the battery 46 can assume a removal state in which the battery is arranged in the battery receptacle 48 and is fixed therein in a locking manner. The customer transfers the battery 46 to the removal state by removing the battery from the battery receptacle 48. In particular, the battery 46 is pulled out of the battery receptacle 48 in the removal direction 50 in a rearward direction.
[0074] In the inserted state, the electrical contact elements of the battery 46 can cooperate with the electrical contact elements 52 arranged on the battery receiving portion 48. In the present case, the contact elements 52 are arranged on the side of the battery receiving portion 48 facing away from the rear side 28 ( Figure 2 ).
[0075] The tool holder 54 is arranged on the housing 18 on the bottom side 26. In the working position, the tool unit 12 can be partially accommodated in the tool holder 54 with the section 56. The tool unit 12 can be removed from the housing 18 by removing the section 56 from the tool holder 54. It is advantageous to separate the tool unit 12 from the housing 18, for example, in order to repair the tool unit 12, in particular to sharpen the tool 16.
[0076] Alternatively or additionally, it may be provided that different types of tool units are used in the tool device 10 , which tool units differ from one another with respect to at least one tool 14 .
[0077] Viewed from the rear side 28 to the front side 30 , the tool receptacle 54 adjoins the electrical receptacle 48 and extends substantially as far as the front side 30 .
[0078] In order to form the tool receptacle 54, a housing part 58 ( Figure 4 and 8 ). For example, the electric motor 40 is held on the housing part 58 .
[0079] The housing part 58 delimits the tool receiving portion 54 upward in the height direction of the tool device 10. Figures 1 to 4 As shown, since the tool device 10 is usually turned over for maintenance purposes, the housing part 58 can be regarded as forming the “bottom” of the tool receptacle 54 .
[0080] The tool receptacle 54 is laterally delimited by edges 60 and 62 formed by the housing half shells 20 and 22. The edges 60, 62 protrude beyond the housing part 58, so that a recess 64 is formed between the edges between the half shells 20, 22. A lead-through 66 for the tool unit 12 is present on the front side 30.
[0081] To close the tool receptacle 54 , a cover element 68 is provided, which represents a blocking element 69 according to the present invention. The cover element 68 can be viewed in a broad sense as a housing part 70 of the housing 18 .
[0082] The cover element 68 is arranged on the underside 26 and is designed in the present case in the form of a plate. The cover element 68 is flat on the underside 26, thereby making it difficult for dust to adhere and facilitating cleaning.
[0083] A cover element 68 is inserted into the recess 64 , wherein the edge of the cover element 68 adjoins the edges 60 , 62 .
[0084] The cover element 68 is held on the edges 60, 62 in a displaceable manner relative to the housing 18. In this case, the edges 60, 62 form a guide device 72 and in each case a guide element.
[0085] The cover element 68 can be displaced relative to the housing 18 in the longitudinal direction of the tool device 10. There is the possibility of displacing the cover element 68 in the direction of the rear side 28. This corresponds to a movement in the removal direction 50. Conversely, the cover element 68 can be displaced back in the direction of the front side 30, counter to the removal direction 50.
[0086] The cover element 68 is inserted between the half shells 20, 22 in such a way that it is held captive on the housing 18. The half shells 20, 22 are provided with stop elements 74 on the edges 60, 62, so that the cover element 68 can only be moved back to the end of the tool receptacle 54 and cannot be separated from the edges 60, 62.
[0087] The forward movement path of the cover element 68 is defined by a locking element 134 disposed on the tool receptacle 54 , as will be discussed below.
[0088] The drive element 42 is guided through the housing part 58 and projects from there into the tool receptacle 54 .
[0089] Especially from Figure 8 and 9 As can be seen in FIG. 1 , the knives 16 are disposed flat against each other. An elongated hole (not shown) extending in its longitudinal direction is formed on the respective knives 16 on a section 56 that can be inserted into the tool holder 54 .
[0090] The tool 16 has a coupling member 76 on the section 56, in which a through opening 78 is formed. Fig. 9 FIG. 7 shows only a coupling member 76 having a through-opening 78. The through-opening 78 is non-circular and in the present case is in particular approximately elliptical.
[0091] The drive member 80 is inserted into the through-opening 78. The drive member 80 is a disk with a circular shape and forms an eccentric element. Two through-openings 82 are formed eccentrically in the drive member 80. Two further through-openings 84 are formed laterally next to the through-openings 82 in the drive member 80.
[0092] The tool unit 12 comprises a holding member 86 which covers the chisel 16 . Two through-openings 88 are formed in the holding member 86 , which are arranged at a distance from one another and are located above the elongated hole in the chisel 16 .
[0093] Furthermore, a through opening 90 is formed in the holding member 86. A connecting member 92, which is in the form of a circular disk, is accommodated in the through opening 90. A receptacle 94 is formed in the center of the connecting member 92. The receptacle 94 is shaped in cross section in such a way that it cooperates with the drive element 42. The drive element 42 rotating about the axis 44 can thus also drive the connecting member 92 to rotate about the axis 44.
[0094] A through-opening 96 is formed laterally next to the receptacle 94 in the connecting member 92 . The through-opening 96 can be aligned with the through-openings 84 of the two drive members 80 .
[0095] The fixing member 98 in the form of a pin penetrates through the through-opening 96 of the connecting member 92 and the through-opening 84 of the drive member 80 and is fixed by force or form closure in such a way that the drive member 80 and the connecting member 92 are connected to one another.
[0096] The drive element 42 passes through different through-openings 82 in the drive links 80 , so that the drive links 80 are not aligned one above the other. Instead, the drive links 80 are each positioned eccentrically relative to the drive element 42 , but in opposite directions.
[0097] When the drive element 42 rotates, the drive members 80 are thereby each rotated eccentrically about the axis 44 and move the tool 16 in the opposite direction.
[0098] The tool unit 12 further comprises a reinforcement element 100 in the form of a profile, which is placed on the housing part 58 and engages therewith in a form-fitting manner, thereby securely holding the tool unit 12 in the tool receptacle 54 both in the longitudinal direction and in the transverse direction.
[0099] An orientation element 102 in the form of a bolt 104 is arranged in a fixed position on the housing part 58. The bolt 104 penetrates through the elongated hole of the tool 16 and one of the through-openings 88 and serves to additionally fix the tool unit 12 in the tool receptacle 54. A further orientation element 106 in a fixed position is arranged at a distance from the orientation element 102 and is also designed as a bolt 108. The bolt 108 also penetrates through the elongated hole of the tool 16 and another through-opening 88 therein.
[0100] Especially from Figure 3 It can be seen that the section 56 is arranged in the tool receptacle 54 in the working position of the tool unit 12. The tool unit 12 is thus engaged with the drive element 42 and the two bolts 104 and 108. The tool 16 and the reinforcement element 100 penetrate through the leadthrough 66 and protrude from the housing 18.
[0101] The cover element 68 can occupy a blocking position. Figure 1 and 2 In the blocking position, the cover element 68 covers the tool receptacle 54 and the section 56 of the tool unit 12 contained in the tool receptacle. If the cover element 68 occupies the blocking position, the tool unit 12 cannot be removed from the tool receptacle 54, which lays the basis for the designation of the blocking element 69.
[0102] Only after the cover element 68 is moved from the blocking position to the release position can the tool unit 12 be removed from the tool receiving portion 54. If the cover element 68 occupies the release position, the cover element 68 is moved relative to the housing 18 to such an extent that the removal opening of the tool receiving portion 54 is exposed, so that the tool unit 12 can be removed. Figure 3 and 4 ). In the released position of the cover element 68 , the tool unit 12 or another type of tool unit can be inserted into the empty tool receptacle 54 .
[0103] A particular advantage of the invention is that the cover element 68 can only be moved into the release position when the battery 46 is removed from the battery receptacle 48 .
[0104] This is not possible if the battery 46 is inserted in the battery receptacle 48. The battery 46 and the cover element 68 comprise corresponding contact elements 110 and 112, respectively, the contact element 110 being arranged on the end side of the battery 46 facing the cover element 68. The contact element 112 is arranged on the end side of the cover element 68 facing the battery 46.
[0105] In the blocking position of the cover element 68, when the battery 46 is inserted into the battery receiving portion 48 ( Figure 1 ), the abutment elements 110, 112 abut against each other. This prevents the cover element 68 from moving. For this purpose, the battery 46 is first removed from the battery receiving portion 48. As a result, the battery receiving portion 48 is exposed ( Figure 2 ). The cover element 68 can then be moved from the blocking position, in this example, covering the section 56 and closing the tool receiving portion 54, above the battery receiving portion 48 and transferred to a movable release position, so that the tool unit 12 can be removed ( Figure 3 and 4 ).
[0106] For handling, it is advantageous if the removal of the battery 46 and the displacement of the cover element 68 take place in both cases in the removal direction 50 .
[0107] The advantage in the released position is that the cover element 68 at least partially covers the battery receptacle 48 to the extent that it covers the contact element 52. This protects the contact element 52 from dust and moisture. Figure 3 and 4 It can be seen that in the tool device 10 the battery receptacle 48 is even substantially completely covered.
[0108] exist Figures 5 to 7 The embodiment of the tool device according to the invention shown in FIG. 1 and assigned reference numeral 120 differs from the tool device 10 , for example, in the last-mentioned aspect. Figures 5 to 7It can be seen that in the tool device 120, the housing 18 is designed longer than the housing of the tool device 10. A housing section 122 is arranged upstream of the handle device 32. The front and rear sections of the housing 18 in the longitudinal direction are designed identically to the housing 18 of the tool device 10.
[0109] In the tool device 120 , the cover element 68 therefore only partially covers the battery receptacle 48 in the released position.
[0110] A further difference between the tool devices 10 and 120 is that in the tool device 120 the cover element 68 can be moved from the blocking position in the direction of the release position. However, the release position can only be assumed when the battery 46 is removed, as in the tool device 10.
[0111] Figure 5 The situation is shown in which the cover element 68 has been moved from the blocking position until the contact elements 110 , 112 are in contact and the battery 46 prevents a further movement of the cover element 68 .
[0112] In this case, the tool receptacle 54 is partially released, but the tool unit 12 cannot be removed therefrom.
[0113] The cover element 68 can be locked in the blocking position by means of a locking device 130 . This secures the cover element 68 against undesired and erroneous movement into the release position. The locking device 130 comprises a first locking element 132 and a second locking element 134 .
[0114] The locking element 132 is arranged on the cover element 68 and is in particular fastened thereto. The locking element 132 is designed as a knob 138 that can be rotated about an axis 136. The axis 136 is perpendicular to the plane of the cover element 68. The knob 138 can be actuated manually and without tools.
[0115] Especially from Fig.10 and 11 It can be seen that a recess 140 in the form of a notch is formed on the knob 138. The recess 140 includes a radial section 142 and an arc section 144, which extend radially or in the circumferential direction of the axis 136. On the edge of the arc section 144, a strip 146 is arranged.
[0116] The second locking element 134 is formed in the present case by the bolt 108. The locking element 134 comprises an annular groove 148 near the free end.
[0117] When the cover element 68 is closed, the radial section 142 is oriented toward the locking element 134. As a result, the locking element 134 can be inserted into the recess 140. Fig.10 Shown in.
[0118] By rotating about the axis 136 (such as Fig.10 By turning the knob 138 (indicated by the arrow 150 in the figure), the locking element 134 can be introduced into the arc section 144. As a result, the strip 146 is embedded in the annular groove 148 in a form-fitting manner, and the locking elements 132 and 134 are held together by the form-fitting. Figures 2 to 4 and 11.
[0119] Conversely, for unlocking, the knob 138 is turned counter to the direction of the arrow 150 until the locking element reaches the radial section 142. Subsequently, when the battery 46 is removed, the cover element 68 can be transferred from the blocking position into the release position.
