Description

Technical Field

[0001] The invention relates to a switching element for a hand-held power tool or as a component part of a hand-held power tool, the hand-held power tool having an electric drive motor which can be switched by means of the switching element, wherein the switching element has a switching element housing with a switching element chamber, in which a switching actuator which can be adjusted between at least two switching positions is arranged for actuating an electric switching element, the switching actuator being movably coupled to a actuating element which is arranged outside the switching element housing and can be adjusted between at least two actuating positions by means of a transmission element, wherein the transmission element passes through a through-opening at the wall of the switching element housing, so that the switching actuator can be adjusted by adjusting the actuating element for actuating the switching element. Background Art

[0002] Such a switching element is described in EP 2 395 527 A1. The switching element has a magnetic transmitter as a switching actuator, which is accommodated in the switching element chamber of the switching element housing. By means of a squeezing actuation of the actuating element, the switching actuator can be displaced, so that in this way the drive motor can be switched on and its rotational speed can be changed.

[0003] In order to set the respective rotational direction of the drive motor, for example in order to screw in and out threaded fasteners, a separate switching element is provided, which also operates magnetically. However, the magnetic switching actuator of the rotational direction switching element tends to attract ferromagnetic dust, chips and the like, so that the hand-held power tool can no longer be used. Summary of the Invention

[0004] Accordingly, it is an object of the present invention to provide an improved switching element for a hand-held power tool and a hand-held power tool equipped with such a switching element.

[0005] To solve this problem, in the case of a switching element of the type mentioned at the beginning, it is provided that a rotational bearing is arranged at the through-opening, at which the transmission element is rotatably supported about a rotational axis.

[0006] The rotational bearing simply enables, for example, the switching element to be designed as a rotational direction switching element, that is to say, the rotational direction of the drive motor can be preset by adjusting the switching actuator, for example the clockwise rotation (Rechtslauf) or counterclockwise rotation (Linkslauf) of the tool receptacle of the hand-held power tool.

[0007] For example, the rotational bearing is designed as a sliding bearing. However, the rotational bearing can also comprise a rolling bearing, for example a ball bearing or a roller bearing.

[0008] Preferably, the rotary bearing is part of the through-opening or part of the following wall where the through-opening is arranged. For example, the through-opening itself is designed as a support receptacle for the actuating element.

[0009] However, the rotary bearing, which supports the actuating element about its axis of rotation, can also be arranged directly next to the through-opening. For example, the rotary bearing can include a rolling bearing or a sliding bearing, which is designed as a rotary bearing separate from the wall (where the through-opening is arranged) or as a separate component. In this design, the through-opening can, for example, not be designed as a rotary bearing for the actuating element itself. However, in this case, it is also advantageous that the actuating element passes through the through-opening but is sealed at the through-opening.

[0010] Preferably, the axis of rotation passes through the wall where the rotary bearing is arranged. For example, the axis of rotation extends parallel to the side wall surface of the wall, that is to say, the rotary bearing is arranged directly in the wall, but has an axis of rotation, which, for example, is parallel to the wall of the switching element housing and extends in the wall.

[0011] However, the preferred concept is that the axis of rotation is angled, in particular at a right angle, with respect to the wall surface of the wall where the rotary bearing is arranged. However, it is also possible without any problem for the axis of rotation to be angled with respect to the wall surface, that is to say not at a right angle. For example, the transmission element is designed as a shaft element or has a shaft section, which is rotatably supported about the axis of rotation in the rotary bearing, and the axis of rotation passes through the wall surface at an angle.

[0012] The preferred concept is that the switching element chamber is closed except for the through-opening, in which the rotary bearing is accommodated or which forms the rotary bearing. That is to say, the transmission element closes the through-opening or is received in the through-opening in a sealing manner. The switching element chamber seals the switching actuator, so that environmental influences, such as dust, in particular ferromagnetic dust, cannot penetrate into the switching element housing and / or the switching element chamber in which the switching actuator is arranged.

[0013] At the through-opening, an anti-displacement profile or anti-displacement portion is preferably provided for holding the transmission element against displacement parallel to or along its axis of rotation. That is to say, the transmission element is preferably held against displacement about its axis of rotation at the through-opening. The anti-displacement portion or anti-displacement profile includes, for example, components of form-fitting profiles that engage into one another, wherein one form-fitting profile is arranged at the transmission element and the other form-fitting profile is arranged at the through-opening or at the wall of the switching element housing having the through-opening. The form-fitting profiles preferably enable the rotatability of the transmission element about its axis of rotation and / or support the transmission element about its axis of rotation and / or form part of a rotational bearing arranged at the through-opening.

[0014] The anti-displacement profile includes, for example, an annular flange that extends partially or completely annularly about the axis of rotation and engages into a partially or completely annular annular groove. The annular flange can be arranged at the transmission element and the annular groove can be arranged at the through-opening. However, conversely, it is also possible that the annular flange is arranged at the through-opening, that is to say, for example, projects radially inwards into the through-opening, while the annular groove is arranged at the transmission element. It is understood that the annular flange can include two or more partially annular annular flange sections, between which there is an angular spacing about the axis of rotation. It is further understood that at least two pairs of correspondingly engaging annular flanges and annular grooves can be provided at an axial spacing with respect to the axis of rotation of the transmission element. The annular flange is, for example, disc-shaped. The annular flange and / or the annular groove are preferably integral with the transmission element.

[0015] The annular flange and the annular groove can be, for example, part of a seal to be explained later. The annular flange and the annular groove particularly advantageously form part of a labyrinth seal. However, it is also possible that the annular flange and the annular groove do not have a sealing function, for example when they are only partially annular.

[0016] At the through-opening and / or at the rotational bearing, a seal is preferably arranged. Preferably, the rotational bearing and / or the through-opening are designed as a seal or have a seal. For example, components of a labyrinth seal can simultaneously be part of the rotational bearing or the through-opening. Preferably, a component complementary to the seal, for example also a component of a labyrinth seal, is arranged at the transmission element.

[0017] The seal can be, for example, a sliding seal of the type of a sliding bearing, including an O-ring or the like.

[0018] Preferably, the seal surrounds the transmission element annularly. For example, it is advantageous if the seal includes a sealing flange that engages in an annular seal receptacle. The sealing flange is arranged, for example, at the transmission element, while the annular seal receptacle is arranged at the bearing receptacle of the rotary bearing. However, it is also feasible that the rotary bearing has an annular sealing flange that projects radially inwards to the transmission element and engages in an annular seal receptacle at the transmission element. Also suitable as a sealing flange is an O-ring. In particular, it is feasible that an O-ring or other rubber seals or elastic seals are also arranged at the sealing flange.

[0019] Preferably, the seal includes a labyrinth seal or is formed by it. For example, the previously mentioned sealing flange can be designed in the type of a labyrinth seal. Preferably, only a labyrinth seal is provided between the transmission element and the through-opening and no elastic seal is provided. The labyrinth seal can simultaneously form a sliding bearing or form part of a sliding bearing. Thereby, for example, when the transmission element rotates in the rotary bearing or the sliding bearing, little wear can be achieved.

[0020] The actuating element for driving or actuating the rotatable transmission element is preferably supported translationally at the sliding bearing with respect to the switch housing. The sliding bearing can be part of the switch housing or arranged at the switch housing. Preferably, the sliding bearing is arranged at the machine housing of the hand-held power tool.

[0021] Between the switch and the actuating element, especially between the transmission element and the actuating element, a transmission mechanism is preferably arranged. Obviously, it is feasible that, for example, a transmission mechanism is arranged between the transmission element and the switching actuator.

[0022] The transmission mechanism can be arranged completely or partially within the switch housing, especially within the switch chamber. Preferably, however, the transmission mechanism is arranged completely or integrally outside the switch housing. Thereby, for example, only a section of the transmission element and the switching actuator are arranged within the switch housing or the switch chamber.

[0023] The transmission mechanism is preferably designed or arranged to convert the linear or translational movement of the actuating element into a rotational movement of the switching actuator. This conversion can occur, for example, by means of a wedge drive or an inclined plane drive. A toothed drive (especially a combination of a rack and a gear) can also perform the previously mentioned function. For example, a rack or a rack section is arranged at the actuating element and meshes with a gear or a circumferential toothing at the transmission element. In a particularly preferred embodiment shown in the drawing, the transmission mechanism includes a crank drive or is formed by it.

[0024] The transmission drive preferably has a drive part coupled to and / or driven by the actuating element and a driven part for driving or carrying the switching actuator. Preferably, the drive part and / or the driven part are arranged at the transmission element. The transmission element particularly has the drive part and the driven part in one piece.

[0025] Advantageously, the transmission element is designed as a crankshaft element or a crankshaft or is rotationally connected or fixedly coupled to the crankshaft. For example, the transmission element has a shaft section which can be rotatably supported at the through-opening of the switching element housing. A crank arm projects at an angle, in particular at a right angle, from the shaft section. Advantageously, an actuating arm projects at an angle, in particular at a right angle, from the crank arm. The shaft section and the actuating arm preferably extend parallel to each other or have a longitudinal extension extending parallel to each other. The shaft section, the crank arm and the actuating arm form, for example, a stepped profile or extend stepwise in a side view. Preferably, only the shaft section engages in the switching element housing and / or passes through the through-opening. The shaft section projects, for example, at opposite sides before the through-opening. Furthermore, advantageously, at least one seal for sealing the shaft section at the switching element housing and / or one of the anti-displacement profiles and / or at least one of the annular grooves or annular flanges is arranged at the shaft section for engagement in another of the annular grooves or annular flanges at the switching element housing, in particular at the through-opening.

[0026] Advantageously, the transmission element has a shaft section which projects freely in front of the wall or side wall of the switching element housing having the or a through-opening and projects into the switching element chamber of the switching element housing limited by the wall or side wall. Advantageously, one of the seals and / or anti-displacement profiles mentioned above and / or an annular flange extending partially or completely annularly about the axis of rotation and / or a partially or completely annular annular groove are arranged at the shaft section. At least one annular or partially annular annular flange of the shaft section engages in the annular groove at the through-opening, while the annular groove at the shaft section is in engagement with a projection projecting radially from the axis of rotation at the through-opening, for example an annular flange.

[0027] In these two embodiments of the transmission element mentioned above, a shaft section is provided. The switching actuator is preferably arranged at the shaft section. The actuating arm or crank arm of the transmission element which is designed to rotationally manipulate the transmission element about the axis of rotation and is arranged at the shaft section preferably projects radially from the shaft section further away from the axis of rotation than the switching actuator. The switching actuator is, for example, a contactless switching transmitter, in particular a magnetic transmitter or a magnet.

[0028] However, it is also possible that the transmission drive reverses the linear movement direction of the actuating element in a first direction into a linear adjustment of the switching actuator in a second direction different from the first direction (for example a direction at an angle to the first direction, in particular a right angle to the first direction).

[0029] Preferably, no locking profile is arranged at the transmission drive mechanism, and when one operating element is in a predetermined operating position, the other operating element can be locked by means of the locking profile.

[0030] The transmission element is preferably supported not only at the rotational support arranged at the wall of the switching element housing, and in addition is supported at the switching element housing at a longitudinal distance with respect to the rotational axis, for example at the wall of the switching element housing opposite to the through-opening. Advantageously, the transmission element is rotatably supported at opposite walls of the switching element housing with respect to its rotational axis.

[0031] An advantageous concept is provided such that the switching element not only has the aforementioned operating element and the switching actuator, but the operating element forms a first operating element and the switching actuator forms a first switching actuator for operating the switching element, which presents a first switching element. In addition, the switching element has a second operating element arranged outside the switching element housing and adjustable between at least two operating positions and a second switching actuator operable by the second operating element for operating a second electrical switching element. That is to say, the switching element can perform a second function by means of the second switching actuator and the second electrical switching element.

[0032] The second operating element and the second switching actuator are preferably kinematically coupled by means of a second transmission element, which passes through a second through-opening in the wall of the switching element housing. The wall can be the same wall at which the transmission element, at which the first switching actuator can also be rotatably supported, is located.

[0033] Although the second transmission element can also be rotatably supported with respect to the switching element housing. However, preferably, the second transmission element is supported linearly along a sliding axis with respect to the switching element housing.

[0034] Advantageously, the second transmission element can be linearly displaced along the sliding axis through the through-opening, for example, can be displaceably supported at the through-opening. Here, particularly preferably, the sliding axis is parallel to the rotational axis of the first switching actuator.

[0035] By means of the second transmission element and the second switching actuator, for example, a drive motor can be switched on and / or switched off and / or its rotational speed can be changed.

[0036] Preferably, the operating elements are arranged on the same side of the switching element housing. Thereby, the two operating elements can be operated by the operator from the same side.

[0037] Advantageously, the axis of rotation of the first transmission element and the sliding axis of the second transmission element enclose an angle of less than 90°, in particular less than 60°, and particularly preferably less than 30° relative to one another.

[0038] Advantageously, the axis of rotation of the first transmission element and the sliding axis of the second transmission element are parallel to one another or extend parallel to one another.

[0039] At least one of the actuating elements or both of the actuating elements expediently have a locking profile for locking the other actuating element. Particularly advantageously, the actuating element and / or the locking profile of the actuating element are designed for mutual locking. For example, it is feasible that one of the actuating elements locks the actuation of the other actuating element from the first actuating position to the second actuating position in a predefined actuating position (for example, in the intermediate actuating position). Thereby, it can be set, for example, that the actuating element that can be moved in a sliding manner locks the actuation of the first actuating element when it is adjusted from its non-actuated initial position into the actuating position, so that when the drive motor is already running, for example, the direction of rotation of the drive motor cannot be changed. However, it is also feasible that the actuating element for the direction of rotation (preferably, the first actuating element) only allows the actuation of the second actuating element when the first actuating element is in a defined first or second actuating position (however, not in the intermediate position between the first and second actuating positions), and by means of the second actuating element, the drive motor can be switched on, for example. In the first and second actuating positions, the clockwise or counterclockwise operation of the drive motor can be set by means of the first actuating element, for example.

[0040] Preferably, the locking profile is arranged directly at the respective actuating element, in particular at its actuating body or actuating housing.

[0041] The switching element chamber accommodating the first switching actuator expediently forms a first switching element chamber. The second switching actuator is arranged in a second switching element chamber separated from the first switching element chamber. Thus, that is to say, the two switching actuators are arranged in separate switching element chambers.

[0042] For example, it is feasible that the first and second switching element chambers are separated or isolated from one another by a partition wall. The partition wall can be connected, for example, to the side wall or peripheral wall of the switching element housing.

[0043] Furthermore, it is advantageous that the first switching element chamber is sealed relative to the second switching element chamber. For example, there are provided sealing profiles, sealing protrusions or the like, which engage with one another and seal and separate the switching element chambers from one another. Advantageously, at least one labyrinth seal and / or an elastic seal or a rubber seal is provided between the first and second switching element chambers.

[0044] Suitably, the second switching element chamber is closed or sealed except for the second through-opening or bearing opening for the second transmission element. For example, the first and / or second switching element chambers are surrounded by a peripheral wall, a respective bottom wall, and a covering wall.

[0045] At the second through-opening or bearing opening for the second transmission element, a seal is preferably arranged, such as an annular seal, an O-ring, or the like. The sealing measures already mentioned in connection with the first transmission element (i.e., for example, a sealing flange engaged in an annular seal receptacle) are also feasible without problems in the second transmission element.

[0046] Preferably, in the switching element, it is arranged such that it has a spring assembly for loading at least one switching actuator, in particular the second switching actuator, into a predetermined switching position. A latching assembly, clamping assembly, or other fixing assembly for latching or fixing at least one switching actuator in a predetermined switching position is advantageous. For example, the first actuating element or a structural component coupled to the first actuating element can be latched by means of the latching assembly or fixing assembly in order to, in particular, fix the rotational direction preset of the switching element.

[0047] The spring assembly or the latching assembly can act directly on the switching actuator, but also on the actuating element that actuates the switching actuator accordingly.

[0048] At least one switching actuator, preferably the two switching actuators, is designed as a magnet or has a magnetic transmitter and / or a contactless switching transmitter, such as a capacitive or optical transmitter, or is designed in such a way. Obviously, other actuation principles, such as mechanically actuated actuation principles, optical transmitters, etc., are also feasible without problems. The switching actuator can also, for example, actuate an electrical contact, for example, between a closed position and an open position.

[0049] At least one of the electrical switching elements is suitably arranged outside the switching element housing and / or at the conductor plate. The conductor plate suitably forms part of a current-carrying mechanism for energizing the drive motor of the hand-held power tool. Thereby, for example, one or more switching elements that can be actuated by the switching element can already be arranged at the conductor plate. Thus, the switching element can have switching elements, but this is not necessary. It is sufficient that the switching element forms part of the conductor plate, while at least one switching actuator forms part of the switching element according to the invention.

[0050] The electrically switchable element that can be switched by a switching element is advantageously arranged at the conductor plate, wherein the respective switching element is preferably arranged in a sandwich-like manner between the switching element housing and the conductor plate. Alternatively or additionally, it is advantageous for the conductor plate and the switching element housing to be cast with a casting material. Preferably, the switching element housing or the switching element has a sealing projection that projects into the conductor plate and limits the accommodation capacity for the respective switching element. Thereby, for example, it is possible that the casting material does not flow to the switching element, but rather remains outside the cavity for the switching element through the sealing projection so to speak.

[0051] The invention furthermore relates to a hand-held power tool having a switching element according to the above description.

[0052] Preferably, the hand-held power tool according to the invention is a screwing machine and / or a drilling machine. However, other hand-held power tools can also be designed without problems with the switching element according to the invention, in particular such hand-held power tools in which the rotational direction of the drive motor can be preset with the switching element according to the invention, for example clockwise operation or counterclockwise operation.

[0053] The switching element housing is preferably two-piece and / or has mutually matching housing sheaths that delimit one or more switching element chambers in the state of being arranged against each other. For example, the switching element housing includes a housing bottom that is covered by a housing cover. Side walls projecting in the direction towards the respective other part can be provided at the housing bottom and the housing cover respectively. A seal is preferably provided between the two housing parts (i.e., the housing bottom and the housing cover). The housing parts (that is to say the housing bottom and the housing cover) can complementarily delimit through openings or support openings for one or two of the previously mentioned transmission elements.

[0067] The hand-held power tool machine 10 has a machine housing 11 in which a drive train 15 with a drive motor 16 is arranged. The drive train 15 is in a drive part 12 that projects from the drive part by a handle part 13 that can be grasped or enveloped by an operator. The handle part 13 projects from the drive part 12, for example, in the type of a pistol grip, angled, in particular at an angle of approximately 80 - 90°.

[0068] The drive motor 16 can directly drive a driven element 19 having a corresponding tool receptacle in which, for example, a screwdriver bit, a drill or the like can be accommodated. However, currently a transmission mechanism 17 is connected between the drive motor 16 and the driven element 19.

[0069] To control and operate the transmission system 15 and thus the entire hand-held power tool 10, a control module 20 is provided, which includes a current supply mechanism 21. The control module 20 is basically located in the handle part 13. Regarding the machine housing 11, it should also be noted that only other housing parts 14 at the rear are shown in the drawing, while the complementary housing parts that, together with the shown housing parts 14, enclose the interior space of the machine housing 11 are not visible in the drawing.

[0070] The current supply mechanism 21 includes a board 22 at which different electronic and electrical structural components (not visible in the drawing) are arranged for controlling the drive motor 16, in particular for supplying current thereto. However, switching elements 23 and 24, for example magnetic sensors, are schematically shown. By means of the switching element 23, the current supply mechanism 21 and thus the drive motor 16 can be switched on or off, for example. In addition, the rotational speed of the drive motor 16 can be preset by means of the switching element 23. The switching element 23 can also be referred to as a throttle switching element. The direction of rotation of the drive motor 16, for example clockwise or counterclockwise operation, can be set by means of the switching element 24.

[0071] The current supply mechanism 21 is connected or can be connected via a line 25 to the drive motor 16, in particular to the excitation coil of the excitation coil assembly (not more specifically labeled in the drawing) thereof. The drive motor 16 is, for example, a brushless motor or an electronically commutated motor. However, without any problem, the switch 30 can also be used with a universal motor or other electric motors, by means of which the switching elements 23 and 24 can be switched.

[0072] The current supply mechanism 21 is connected or can be connected via a line 26 to a supply interface 28 through which the hand-held power tool 10 can be supplied with electrical energy. For example, an electrical supply line, such as a mains cable, can be provided at the supply interface 28 in a manner not shown for connection to an electrical supply network, for example an electrical supply network having an alternating voltage of 110 volts or 230 volts. However, currently the hand-held power tool 10 is a wirelessly operable hand-held power tool. The supply interface 28 is for connecting a schematically illustrated electrical energy storage 29, such as a battery pack. The electrical energy stored in the energy storage 29 is used to supply the current supply mechanism 21 and thus the drive motor 16.

[0073] However, when the hand-held power tool machine 10 operates in an environment particularly exposed to dust, there is a risk that sensitive electrical structural components, switching elements or the like may become soiled. Particular problems are caused by ferromagnetic dust, which can magnetically adhere to the magnetic transmitter, for example to the magnetic transmitter of a switching element according to EP 2 395 527 A1. However, this problem does not occur or occurs to a significantly reduced extent in the switching element 30.

[0074] The switching element 30 includes actuating elements 31 and 32 by means of which the switching elements 23 and 24 can be actuated. That is to say, correspondingly here, the drive motor 16 can be switched on and off and influenced in terms of its rotational speed by means of the actuating element 31, while the actuating element 32 is provided for presetting the direction of rotation of the drive motor 16.

[0075] The switching element 30 has a switching element housing 33 in which separate switching element chambers 34 and 35 are provided. The switching element housing 33 includes a housing bottom 36 which is closed by a housing cover 37. The two switching element chambers 33 and 34 are closed at the peripheral side, except for the through openings 53, 54, at the side walls 51, 52 of the switching element chambers 34 and 35. In addition, there is a partition wall 42 between the switching element chambers 34 and 35, which separates the switching element chambers 34 and 35 from each other.

[0076] The housing bottom 36 and the housing cover 37 form complementary housing parts 36A, 37A which enclose the switching element chambers 34, 35.

[0077] The housing bottom 36 has a bottom wall 45 from which a peripheral wall 46 projects. The housing cover 37 has a covering wall 47 from which a peripheral wall 48 projects. The end sides of the peripheral walls 46, 48 and the wall sections of the housing bottom 36 and the housing cover 37 which form the partition wall 42 face each other with their end sides.

[0078] At the end sides of the peripheral walls 46, 48 and the partition wall sections of the partition wall 42, there are provided sealing projections 38, 39 for restricting the switching element chambers 34, 35 and complementary sealing receptacles 40, 41, the sealing projections 38, 39 engaging sealingly into the sealing receptacles and thereby forming seals 38A, 39A. The seals 38A, 39A seal the switching element chambers 34, 35 relative to each other and relative to the surroundings. The sealing projections 38, 39 are designed, for example, in the form of springs which engage into the sealing receptacles 40, 41 designed as receiving grooves.

[0079] The sealing projections 38, 39 together with the sealing receptacles 40, 41 form, for example, a labyrinth seal. Instead of the sealing projections 38, 39, a sealing receptacle can be provided without any problem, into which, for example, a rubber seal, in particular in the form of an O-ring, a sealing lip, is inserted. Furthermore, the sealing projections 38, 39 can also be designed as elastic sealing projections or rubber sealing projections.

[0080] It is particularly advantageous if the switching element chambers 34 and 35 are sealed from one another and / or sealed from one another by seals 38A, 39A. For example, the seals 38A, 39A include a sealing section 38B, for example in the manner of a labyrinth seal, which extends along an area 35A where the switching element chambers 34 and 35 directly adjoin one another. For example, the sealing section 38B includes sections of sealing projections 38, 39 and sealing receptacles 40, 41 which engage in one another in the manner of a labyrinth seal.

[0081] Therefore, the two switching element chambers 34, 35 are sealed by the sealing assembly on the one hand from the environment and on the other hand from each other. That is, the switching actuators 65, 75 accommodated in the interior of the switching element chambers 34, 35 are protected from environmental influences.

[0082] The housing bottom 36 and the housing cover 37 are locked to each other by means of a locking assembly. For example, a locking projection 43, in particular a locking hook or the like, is provided at the housing bottom 36, which engages in a locking receptacle 44 of the housing cover 37. The locking projection 43 and the locking receptacle 44 form a locking assembly 43A and are provided, for example, in the region of the peripheral walls 46, 48. Preferably, a plurality of locking projections and locking receptacles arranged at a distance from each other are provided, so that the housing cover 37 is fixedly held at the housing bottom 36. Obviously, bonding, welding or other similar connections of the housing bottom 36 and the housing cover 37 are also possible, so that the two parts are fixedly held at each other and the switching element chambers 34, 35 are sealed.

[0083] A line receptacle 49 is advantageously provided on the switch element housing 33 , for example on the housing cover 37 , which line receptacle is suitable for receiving a line, in particular the line 25 .

[0084] Furthermore, the switching element housing 33 is supported at the conductor plate 22 by means of the support feet 50. By means of the support feet 50, a spacing is provided between the bottom wall 45 and the conductor plate 22, in which spacing switching elements 23, 24, such as semiconductor structural elements, are arranged in a sandwich-like manner. It is feasible that the bottom wall 45 is in contact with the switching elements 23, 24, for example, lying flat against their upper sides facing the switching element 30. However, it is also feasible that there is a spacing between the bottom wall 45 and the switching elements 23, 24. Preferably, a sealing projection 51A projects from the bottom wall 45 in the direction of the conductor plate 22, which limits the internal space in which the switching element 23 and / or the switching element 24 are arranged. That is, the switching element housing 33 is advantageously cast with the conductor 22 by means of a casting material 27A, which is blocked by the sealing projection 51A, so that the switching elements 23, 24 do not come into contact with the casting material 27A, but are accommodated in a cavity that is so to speak enclosed by the casting material 27A, the bottom wall 45 and the conductor plate 22. The casting material 27A forms a casting body 27, which holds the switching element housing 33 at the conductor plate 22 and preferably protects the electrical structural components arranged at the conductor plate 22 against environmental influences.

[0085] The actuating element 31 is connected to the switching actuator 65 by means of a transmission element 60. The switching actuator 65 includes, for example, a magnet or is formed by a magnet 65A, and the switching element 23 can be actuated by the action of the magnet. The transmission element 60 forms part of a sliding guide or a sliding bearing 60A. The transmission element 60 has a shaft section 61, which is connected to the actuating element 31 by means of a holding section 62, such as a holding projection, for example, engaging into the holding receptacle 31A, in particular the plug-in receptacle, of the actuating element. That is to say, the transmission element 60 extends from the actuating element 31 in the direction towards the switching element housing 33 and engages into the switching element housing.

[0086] At the longitudinal end of the shaft section 61 opposite the actuating element 31, a slide block 63 is arranged, which is linearly guided in a slide block guide 57 with respect to a sliding axis S. The slide block guide 57 is provided in the switching element chamber 34, so that the slide block 63 can be displaceably accommodated in the switching element chamber 34 with respect to the sliding axis S or along the sliding axis S. The slide block guide 57 includes, for example, guide projections 57A and guide receptacles 57B at the slide block 63 and the switching element chamber 34.

[0087] The sliding axis S and the rotational axis D are parallel to each other.

[0088] At the slider 63, a switching actuator 65, for example a magnet, is arranged. By adjusting the slider 63 and thus the switching actuator 65 along the sliding axis S, the relative position of the switching actuator 65 with respect to the switching element 22 can be set such that it occupies different switching positions. That is to say, when the actuating element 31 is actuated, for example, starting from the actuating position A corresponding to the off position, in the direction towards the actuating position E (that is to say, the on position) ( Figure 4 ), the magnetic field of the switching actuator 65 actuates the switching element 23, for example in order to switch on or off the drive motor 16 or to change its rotational speed.

[0089] Advantageous measures are provided such that when the actuating element 31 is actuated for the first time in the direction from the actuating position A towards the actuating position E, the switching element 23 is so to speak awakened and activates the remaining components of the current conducting mechanism 21. When the switching element 31 is held unactuated (that is to say occupies the actuating position A) for a predetermined time, the switching element 23 switches off the hand-held power tool 10 or its electronic components, in particular the current conducting mechanism 21, that is to say a sleep mode is implemented, so that the power consumption is minimal or even switched off.

[0090] The switching actuator 65 is spring-loaded in the direction towards the actuating position A by a spring assembly 64A having a spring 64 (which is supported on the side opposite the through-opening 53, that is to say at the support 58). Thus, that is to say, the operator can actuate the switching actuator 65 against the spring force of the spring 64 from the actuating position A in the direction towards the actuating position E by means of the operating force BK.

[0091] At the through-opening 53 (which simultaneously represents a support receptacle for the sliding bearing of the transmission element 60), a seal 66 is preferably arranged. The seal 66, for example a sealing ring, in particular a sealing ring made of foam material and / or an O-ring, is passed through by the transmission element 60 and seals against its outer peripheral edge. In the switching element housing 33, in particular in the side wall 51 in the region of the through-opening 53, a seal receptacle 55 for the seal 66, for example an annular groove, is provided, in which the seal 66 is received. The housing bottom 36 and the housing cover 37 have support receptacles 67 or sub-sections 67A, 67B of the through-opening 53 in the region of the side wall 51. At the support receptacle 67 or the through-opening 53, the transmission element 60 is linearly guided with respect to the sliding axis S. The support receptacle 67 includes, for example, sleeve-shaped sub-sections 67A, 67B arranged at the housing bottom 36 and the housing cover 37.

[0092] In order to actuate the switching actuator 75, a transmission element 70 is provided, which is pivotably supported about a pivot axis D with respect to the switching element housing 33. The transmission element 70 has a shaft section 71, which is substantially within the switching element chamber 35 and passes through a through-opening 54 at the side wall 52 of the switching element chamber 35 or at the switching element housing 33. The through-opening 54 simultaneously forms a bearing receptacle of a rotary bearing 77 at the side wall 52. At the housing bottom 36 and at the housing cover 37, bearing receptacles 79 or sleeve-shaped sub-sections 79A, 79B of the through-opening 54 are provided.

[0093] On the side opposite to the side wall 52, the shaft section 71 is pivotably supported in a bearing receptacle 59 of a rotary bearing 59A. For example, in order to form the bearing receptacle 59, a support section or wall section 59B projects in front of the wall section of the peripheral wall 46 and / or in front of the wall section of the peripheral wall 48.

[0094] Between the bearing receptacle 59 and the rotary bearing 77, a switching actuator 75, for example a magnet 75A, is arranged at the shaft section 71, for example at a receptacle 73, by means of which the switching element 24 can be actuated. Depending on the respective rotational position or angular position of the switching actuator 75 about the pivot axis D, the switching actuator 75 is adjusted between switching positions, which are assigned to opposite rotational directions of the drive motor 16, for example clockwise operation and counterclockwise operation. Here, an actuating element 32, which is designed, for example, as a sliding element, assumes actuating positions R and L.

[0095] The actuating element 32 is supported on the machine housing 11 along an adjustment axis BS. The machine housing 11 has, for example, a bearing receptacle 95, at which the actuating element 32 is displaceably supported with respect to the adjustment axis BS. In the actuating position R, for example, the actuating section 96 of the actuating element 32 projects further in front of one side of the machine housing 11 than the actuating section 97 of the actuating element 32 projects in front of the other opposite side of the machine housing 11. That is to say, the operator presses on one of the actuating sections 96 or 97 in order to actuate the actuating element 32 from the actuating position R into the actuating position L or vice versa.

[0096] In order to transfer the linear movement of the actuating element 32 along the adjustment axis BS into a rotational movement of the transmission element 70 about the pivot axis D, a transmission mechanism 80 is provided. The transmission mechanism 80 is, for example, a crank mechanism 81. For example, a crank arm 72 projects at an angle, in particular at a right angle, from the shaft section 71 of the transmission element 70. An actuating arm 74 projects in turn at an angle from the crank arm 72, wherein the actuating arm 74, the crank arm 72 and the shaft section 71 extend stepwise in a side view. That is to say, the longitudinal axis of the shaft section 71, which corresponds to the pivot axis D, and the longitudinal axis of the actuating arm 74 are parallel to each other.

[0097] The crank arm 72 is rotatable about the axis of rotation D and oscillates about the axis of rotation D in a circular orbit. The crank arm 72 is pivotably received between the drive projections 82 that project from the actuating element 32. That is, a rotary bearing or a swing bearing 83 having a rotary axis or a swing axis K for the actuating arm 74 is provided between the drive projections 82. Thereby, the component of the transmission element 70 disposed outside the switching element housing 33 and the rotary bearing 82 form a crank drive mechanism 81.

[0098] It is schematically shown in the drawings, but it is also possible without any problem, for example, to arrange a gear 172 at the shaft section 71 instead of the crank arm 72, which gear meshes with a tooth section 182 of the actuating element 32, which tooth section is arranged, for example, at the side of the actuating element 32 facing the gear 172 and extends between its actuating sections 96, 97.

[0099] The crank drive mechanism 81 and thus the transmission drive mechanism 80 are arranged outside the switching element housing 33. Conversely, the switching actuator 75, for example a magnet, is arranged inside the switching element housing 33, i.e., inside the switching element chamber 35.

[0100] The actuating arm 74 forms a drive part 74A of the transmission drive mechanism 80 and at the same time of the transmission element 70. The shaft section 71 forms a driven part 71A of the transmission drive mechanism 80 and at the same time of the transmission element 70. The transmission element 70 thus integrally has a drive part 74A and a driven part 71A.

[0101] A seal 76 is arranged at the rotary bearing 77, so that the transition region between the transmission element 70 and the switching element chamber 35 is sealed. For example, the seal 76 includes a sealing flange 78, for example configured as an annular flange 78B, which projects radially outward in front of the shaft section 71 and engages in a sealing receiving portion 56 of the switching element housing 33. The sealing receiving portion 56 includes, for example, an annular groove 56B at the side wall 52.

[0102] Furthermore, by means of the sealing flange 78 and the sealing receiving portion 56, the transmission element 70 is held at the switching element housing 33 so as to be longitudinally displaceable about the axis of rotation D. Thereby, the sealing flange 78 and the sealing receiving portion 56 form anti-displacement profiles 78A and 56A, which hold the transmission element 70 anti-displaceably about the axis of rotation D at the through-opening 54. The anti-displacement profiles 78A and 56A engage form-fittingly with each other and / or have or form a support profile perpendicular to the axis of rotation D, so that the support profile holds the transmission element 70 anti-displaceably about the axis of rotation D. However, the anti-displacement profiles 78A and 56A enable the transmission element 70 to be rotatable about the axis of rotation D with respect to the switching element housing 33.

[0103] Depending on the respective angular position or switching position MN, ML, MR of the switching actuator 75, such as a magnet, the switching element 24 assumes different switching positions, by means of which, for example, clockwise or counterclockwise operation of the drive motor 16 can then be set. The switching positions MN, ML, MR are assigned to and / or are related to the operating positions N, L, R of the operating element 32. In the switching positions MN, ML, MR, the magnetic field of the switching actuator 75 can pass through the switching element 24 in different directions, thereby manipulating the switching element 24 for outputting, for example, different sensor signals or control signals SIG to the control means 21A, such as a microcontroller. By means of the control signal or sensor signal, the switching element 24, for example, pre-sets the control means 21A, i.e., the control means manipulates the current supply means 21 for supplying current to the drive motor 16 in a leftward or rightward rotational direction.

[0104] However, when no definite rotational direction is set, that is, when the operating element 32, for example, occupies the middle or neutral operating position N and the switching actuator 75 occupies the middle, so to speak, undefined switching position MN, the locking profiles 90, 91 are responsible for preventing the operating element 31 from being manipulated from its operating position A into one of the operating positions E. On the other hand, in the case of the operating element 31 being manipulated into one of the operating positions E, a change in the rotational direction of the drive motor 16 is locked, that is, when the operating element 31 is manipulated into one of the operating positions E (that is, the switching-on position of the drive motor 16), the locking profiles 90, 91 prevent the operating element 32 from being adjusted from the operating position R to the operating position L and vice versa.

[0105] The locking profiles 90, 91 act directly on each other. Advantageously, the locking profiles 90, 91 do not act directly on the transmission drive 80 or its components. The locking profiles 90, 91 are suitably not in engagement with and / or not in direct contact with the transmission drive 80 or its components and / or the transmission element 70.

[0106] The locking profiles 90, 91 include, for example, locking projections 92, 93 on the operating elements 31, 32. The locking projection 92, for example, projects beyond the upper side of the operating element 31 facing the operating element 32. The locking projection 92 is designed in particular as a rib. A locking profile 91 in the form of a locking projection 93 projects from the operating element 32. In the operating position N, the locking projections 92, 93 abut against each other, so that manipulation of the operating element 31 in the direction towards one of the operating positions E is not possible.

[0107] There is a free space or a recess next to the locking projection 92, into which the locking projection 93 can engage when the actuating element 32 is adjusted into one of the actuating positions R or L. Then, the actuating element 31 can be adjusted from the actuating position A into one of the actuating positions E. On the other hand, it is then not possible, however, for the actuating projection 93 to be actuated from one of the actuating positions R, L to the respective other actuating position L, R via the actuating projection 92.

[0108] Then, i.e., the locking projection 93 abuts against the side of the locking projection 92 which extends parallel to the sliding axis S.

[0109] Preferably, the actuating element 32 can be latched by means of a latching assembly 98. The latching assembly includes, for example, a latching projection 99 which is fixed in position with respect to the switching element housing 33 and / or the machine housing 11 and engages into one of two latching recesses 99R, 99L in the actuating positions R, L.
