[0112] The following detailed description of the embodiments shown in the figures serves to provide further illustration or clarification and is not intended to limit the scope of the present invention in any way.DETAILED DESCRIPTION

[0113] FIG. 1 shows a first embodiment of the work apparatus 1 according to the present invention in the form of a drilling apparatus 1 in a first state in a perspective view. The work apparatus 1 can alternatively be formed, for example, as a stirring apparatus 1, a trimming apparatus 1, or a ramming apparatus 1.

[0114] The drilling device 1 according to the present invention is a mobile, hand-held, hand-guided, hand-operated and / or hand-portable drilling device 1 for generating a drill hole L in a ground B. For simplicity, only the term “drilling apparatus” will be used hereinafter. The ground B can be, for example, the ground B of a garden, a park, a sports facility, a construction site, an agricultural area, or a forestry area. In other words, the drilling apparatus 1 can be formed as an earth auger.

[0115] In order to create the drill hole L, the drilling apparatus 1 comprises a drilling tool 10 for processing the ground B. The drilling tool 10 can be formed as a drilling tool 10 known from the prior art for generating a drill hole L in ground B and can comprise, for example, a drill head with a cutter and a screw conveyor. The drilling tool 10 can be formed as an interchangeable (replaceable) drilling tool 10.

[0116] The drilling apparatus 1 comprises a drive unit 20. The drive unit 20 comprises an electric motor with a stator and a rotor. The rotor serves as a drive shaft for transmitting a generated torque. The electric motor is supplied with electrical energy, in particular in an operating state of the drilling apparatus 1, by an electrical energy supply device in the form of an interchangeable accumulator. In other words, the drilling apparatus 1 is a drilling apparatus 1 that can be operated autonomously (independently) from a stationary energy source. For reasons of clarity, the electric motor and the energy supply device are not shown in detail in the figures. Alternatively, it is possible for the drive unit 20 to be formed as a combustion engine drive unit 20, which comprises a fuel tank

[0117] A control element 823 on the handle 82 serves for adjusting, in particular for controlling, the power of the drive unit 20, in particular in conjunction with a locking element 822 for blocking and / or releasing the control element 823. The control element 823 can, for example, be configured in the form of a lever. The control element 823 is connected to a power control element (power electronics) of the electric motor.

[0118] The drilling apparatus 1 comprises a drive element 21 to which the drilling tool 10 can be releasably and / or interchangeably mounted, for example by means of a plug connection and a safety plug. The drive element 21 can be formed as a drive pinion with a tooth profile (drill spindle). The drive element 21 can be a direct (immediate) component or, in particular, a section of the rotor. Alternatively, the drive element 21 can be connected to the rotor via a coupling by means of a coupling drum and / or via a gearbox. The drive unit 20 can be coupled to the drilling tool 10 via the drive element 21 in order to drive the drilling tool 10 in a mounted and / or coupled state.

[0119] The location of the drive unit 20 and, in particular, of the rotor can be characterized by a drive axis 20X along which the rotor extends and / or around which the rotor rotates. Depending on the location of the drive unit 20, the drive axis 20X can be arranged essentially parallel or essentially perpendicular to a tool axis 10X of the drilling tool 10, along which the drilling tool 10 extends.

[0120] The drilling apparatus 1 comprises an apparatus frame 30. The apparatus frame 30 serves, among other things, to receive, that is, to arrange the drive unit 20 and to handle (operate), in particular guide, the drilling apparatus 1 by a user.

[0121] The apparatus frame 30 extends in and / or along a respective direction R1, R2, R3 differently. The directions R1, R2, and R3 represent, in particular, directions of the three-dimensional space, which are arranged and / or aligned perpendicular to each other. The first direction R1 can be arranged parallel to the drive axis 20X.

[0122] The apparatus frame 30 is characterized and / or defined in and / or along the first direction R1 by two outer sides, of which the outer sides 30A5 and 30A6 are marked in FIG. 1. The outer side 30A5 represents an upper side of the drilling apparatus 1, and the outer side 30A6 represents a lower side of the drilling apparatus 1, which, when the drilling tool 10 is hidden, is defined, among other things, by the drive element 21.

[0123] In and / or along the second direction R2, the apparatus frame 30 is characterized and / or defined by the outer sides 30A3 and 30A4. In and / or along the third direction R3, the apparatus frame 30 is characterized and / or defined by the outer sides 30A1 and 30A2. The extension of the apparatus frame 30 in the second direction R2 is greater than the extension of the apparatus frame 30 in the first direction R1 and than the extension of the apparatus frame 30 in the third direction R3. With regard to the apparatus frame 30 and / or the drilling apparatus 1 (as a whole), the first direction R1 can represent a vertical direction, the second direction R2 a longitudinal direction, and the third direction R3 a transverse direction, along each of which the apparatus frame 30 and / or the drilling apparatus 1 as a whole extends.

[0124] The apparatus frame 30 can, for example, be formed as a self-contained frame and / or as a cage-shaped frame. The apparatus frame 30 can be formed as a circumferential apparatus frame 30 in at least one view in at least one direction R1, R2, R3. The apparatus frame 30 comprises frame elements and / or frame sections which are formed, among other things or essentially, by tubes, tube segments and / or tube connections with essentially annular-shaped profiles, and of which the frame elements, frame segments and / or frame sections 31Q, 32Q, 35Q, 36Q are marked as cross members, 31L and 32L as longitudinal members, and 31U and 32U as transition sections / transition segments.

[0125] For the arrangement, in particular for the releasable fastening, of the frame elements 31Q and 32Q at defined positions of the apparatus frame 30, the connecting elements 110, 120, 130, 140 are provided, which connecting elements can be formed in one piece or in multiple parts. The frame elements 31Q and 32Q each comprise a handle 81 and 82 and therefore represent so-called handle tubes.

[0126] The drive unit 20 can be arranged completely (as a whole) within the apparatus frame 30, that is, within an inner area 301 of the apparatus frame 30, for example on a mounting plate of the apparatus frame 30. Alternatively, it is possible that the drive unit 20 is arranged at least partially within the apparatus frame 30 and thus protrudes in sections from the apparatus frame 30 in at least one direction R1, R2, R3.

[0127] The drilling apparatus 1 comprises an actuator unit 40. Depending on the respective configuration of the drilling apparatus 1, the actuator unit 40 can be configured for braking the drilling tool 10 and / or the drive unit 20, for switching off the drive unit 20 and / or for disconnecting a coupling between the drive unit 20 and the drilling tool 10. In the embodiment of the drilling apparatus 1 shown in FIG. 1, the actuator unit 40 is formed, for example, as a clutch and couples the rotor of the electric motor to the drive element 21. The clutch can be formed as a releasable and / or switchable clutch.

[0128] In other words, the actuator unit 40 serves to adjust the operation and / or the drive of the drilling apparatus 10 and / or the drive unit 20 in defined situations and / or operating states of the drilling apparatus 1, in particular within a defined period of time from the occurrence and / or detection (sensing) of an occurrence of an event. An adjustment of the operation and / or the drive of the drilling tool 10 and / or the drive unit 20 is made, for example, in the event, in which the drilling tool 10 suddenly gets caught and / or blocked in the ground B and is thus abruptly slowed down by components of the ground B, such as roots or stones, which in turn initiates a twisting of the drive unit 20 and thus of the apparatus frame 30 around the drive axis 20X.

[0129] The drilling apparatus 1 comprises an operating element 50. The operating element 50 serves for activating the actuator unit 40, in particular as a result of detecting (sensing) a twisting of the apparatus frame 30 and / or as a result of the operating element 50 coming into contact with the user. The detection of a twist can be realized, for example, with an angle sensor or with an inertia sensor, in particular in the form of an acceleration sensor. The operating element 50 can be formed in the form of an operable lever, bracket, arm, pedal, or as an operable rod. In the drilling apparatus 1 in FIG. 1, the operating element 50 is formed in the form of a so-called trigger lever, which extends in and / or along a longitudinal direction 50L of the operating element 50. The operating element 50 can be formed in sections in the form of a tube with an essentially annular cross-section.

[0130] According to the invention, the operating element 50 of the drilling apparatus 1 can be adjustably arranged between a standby state and a parking state, in order to keep the operating element 50 at least partially protected by the apparatus frame 30 in the parking state, in particular in at least one direction R1, R2, R3.

[0131] To adjust the parking state, which is characterized by a parking location PL, the operating element 50 is movably mounted on the first frame side profile 31SP. The operating element 50 is pivotably mounted on the first frame side profile 31SP, in particular by means of a bearing unit 60 with a bearing housing 61, about a first pivot axis 60X. The first pivot axis 60X can be arranged and / or aligned essentially parallel to the drive axis 20X. Alternatively, it is possible that the operating element 50 is pivotably mounted about a first pivot axis 60X on the drive unit 20 by means of a bearing unit 60.

[0132] The bearing unit 60 can be formed as a bearing unit 60 that can be operated manually via the operating element 50. Alternatively or additionally, the bearing unit 60 can be formed as an automated motor-driven bearing unit in order to adjust the operating element 50 from the standby state to the parking state and / or from the parking state to the standby state. The operating element 50 comprises a spring element 90 or is coupled to the bearing unit 60 via a spring element 90 in the form of a coil spring. The spring element 90 extends essentially in and / or along the longitudinal direction 50L, thereby realizing the operating element 50 to pivot about a second pivot axis 90X. The first pivot axis 60X and the second pivot axis 90X are arranged and / or aligned differently to each other, in particular essentially perpendicular to each other.

[0133] The standby state of the operating element 50 is, in particular, a state in which the operating element 50 is arranged in a defined location relative to the drive unit 20 and / or the apparatus frame 30 in order to activate the actuator unit 40. The standby state of the operating element 50 can be a prerequisite for an operational state of the drilling apparatus 1. In FIG. 1, the operating element 50 is in the standby state, which comprises a standby location BL of the operating element 50 and / or which is characterized by a standby location BL of the operating element 50. In the standby location BL, the operating element 50 protrudes in sections from the apparatus frame 30 in a view in the first direction R1, in particular in a top view of the drilling apparatus 1. In addition, reference is made to the top view in FIG. 3 in connection with a second embodiment of the drilling apparatus 1, which also shows the operating element 50 in a standby state, which is characterized by the arrangement of the operating element 50 in a standby location BL.

[0134] The parking state is, in particular, a state in which the operating element 50 is in a parking location PL, in particular relative to and / or on the apparatus frame 30, in order to be kept at least partially protected by the apparatus frame 30 in at least one direction R1, R2, R3, for example when subjected to an external stress in the form of an impact. The adjustable arrangement of the operating element 50 in a parking location PL provides, for example, improved transportability of the drilling apparatus 1. In FIG. 1, the operating element 50 in the parking location PL is shown and marked with a dashed line. The parking state can therefore comprise or characterize a transport state of the operating element 50, in which the operating element 50 is in a parking location PL, so that the drilling apparatus 1 can be transported more easily in the course of a transport process.

[0135] Both the standby location BL and the parking location PL can each be characterized by a defined position and / or by a defined alignment of the operating element 50, in particular relative to the apparatus frame 30, the actuator unit 40, and / or the drive unit 20.

[0136] The apparatus frame 30 comprises a first frame side profile 31SP and a second frame side profile 32SP, which are arranged opposite each other and spaced apart from each other in the third direction R3, and which each define the outer side 30A1 and 30A2 of the apparatus frame 30 in the third direction R3.

[0137] The operating element 50 can be subjected to a preload force by the bearing unit 60, for example, in order to be pressed against a frame section of the apparatus frame 30 with a defined force in the standby state and thus in the standby location BL. The frame section thus acts as a stop for the operating element 50 and, in the first embodiment of the drilling apparatus 1, is formed by the transition section / transition segment 31Ü.

[0138] The drilling apparatus 1 comprises a retaining element 70 for locking the operating element 50 in the parking state, that is, in the parking location PL. The retaining element 70 is arranged on the apparatus frame 30, in particular on the cross member 31Q, and is formed to retain the operating element 50 in the parking location PL in the first direction R1 and / or in the second direction R2, supporting the preload force applied to the operating element 50.

[0139] The retaining element 70 can, for example, be formed in the form of a bracket, a clamp or a hook. In addition or alternatively, the retaining element 70 can be formed to be essentially dimensionally stable in sections and / or dimensionally variable in sections. For example, a section of the retaining element 70 can be formed to be essentially reversibly deformable in order to ensure a certain degree of flexibility in the course of the adjustment of the operating element 50 into the parking location PL. In the parking state and thus in the parking location PL, the operating element 50 and the retaining element 70 form a releasable, essentially form-fit retaining connection and / or a releasable, essentially force-fit, in particular a friction-locking, retaining connection. The retaining connection 50, 70 can comprise at least one of the following or be formed as at least one of the following retaining connections: a hook-in connection, a plug-in connection, a snap-in connection, a clamping connection.

[0140] In the parking state and thus in the parking location PL, the operating element 50 is kept protected by the apparatus frame 30 in the three directions R1, R2, R3 and, in particular, is shielded in sections by the apparatus frame 30 in the third direction R3 on the outer side 30A2.

[0141] The parking location PL represents in particular a location and thus a position and / or an alignment in which the operating element 50 is essentially within the apparatus frame 30 and is at least partially spaced apart from frame profiles 30A1, 30A2, 30A3, 30A4, 30A5, 30A6, which each define an outer side of the apparatus frame 30, in order to ensure a protection of the operating element 50 by the apparatus frame 30.

[0142] In a further embodiment of the drilling apparatus 1, the parking state can also comprise a parking location PL in which, depending on the configuration of the operating element 50, among other things, the operating element 50 is kept at least partially protected by the apparatus frame 30, but protrudes from the apparatus frame 30 in at least one direction R1, R2, R3. The parking state can comprise a parking location PL of the operating element 50 in which the operating element 50 protrudes in sections from the apparatus frame 30 in a view in the first direction R1, in particular in a top view of the work apparatus 1, that is the drilling apparatus 1, by a maximum of 20 percent of the total length of the operating element 50 along the longitudinal direction 50L of the operating element 50.

[0143] As already explained, the apparatus frame 30 comprises a first handle 81 and a second handle 82 for handling the drilling apparatus 1 by a user.

[0144] The first handle 81 is arranged between the first frame side profile 31SP and the second frame side profile 32SP on the frame element 32Q, that is on the cross member 31Q, and the second handle 81 is arranged between the first frame side profile 31SP and the second frame side profile 32SP on the frame element 32Q, that is on the cross member 32Q.

[0145] Both the first handle 81 and the second handle 82 are arranged offset in the first direction R1, in particular essentially parallel to the drive axis 20X of the drive unit 20, relative to the frame sections of the apparatus frame 30 in the form of the frame elements 31L and 32L, which each represent longitudinal members of the apparatus frame 30, and relative to the frame sections of the apparatus frame 30 in the form of the transition sections / transition segments 310 and 320 with an offset in the second direction R2 in order to keep the first handle 81 and the second handle 82 essentially protected in the respective direction R1, R2.

[0146] In a view in the second direction R2, in particular in a side view of the work apparatus 1, that is the drilling apparatus 1, the handle 81 and the handle 82 are arranged offset in the first direction R1 inwards toward the inner area 301 of the apparatus frame 30, in particular toward the drive unit 20.

[0147] The first handle 81 is also arranged relative to the frame sections of the apparatus frame 30 in the form of connecting elements 110 and 120, each with an offset in the first and second direction R1, R2. The same applies to the second handle 82 with regard to the connecting elements 130 and 140. The connecting elements 110, 120, 130, 140 represent front sections of the apparatus frame 30, which each define at least partially an outer side 30A1, 30A2, 30A3, 30A4, 30A5 of the apparatus frame 30 in the respective direction R1, R2, R3.

[0148] The frame elements 31L, 32L, 31Q, 32Q of the apparatus frame 30 also serve, among other things, to receive and / or transmit at least part of a stress energy when subjected to external stress. The external stress can be caused, for example, by a tipping event of the work apparatus 1, that is, the drilling apparatus 1. This allows the handles 81, 82 to be kept essentially free of stress in at least one direction R1, R2, R3.

[0149] The cross member 31Q is connected to the frame elements / frame sections / frame segments 31L, 31Ü and 32L, 32U via the connecting elements 110 and 120, that is it is fastened to the frame sections / frame segments 31L, 31Ü and 32L, 32Ü. The same applies to the cross member 32Q in conjunction with the connecting elements 130 and 140. In other words, the apparatus frame 30 comprises a first cross member 31Q for the offset arrangement of the first handle 81 and a second cross member 32Q for the offset arrangement of the second handle 82.

[0150] A maximum distance D82 (see also FIGS. 3 and 4) between the first cross member 31Q and the second cross member 32Q, in particular between the first handle 81 and the second handle 82, in the second direction R2 is smaller than a distance between the opposite front faces 31SF and 32SF of the apparatus frame 30 in the second direction R2 (see also FIGS. 3 and 4).

[0151] As can also be seen from the illustration in FIG. 1, in a view in the longitudinal direction 81L, 82L of the respective handle 81, 82, which is parallel to the third direction R3, the respective frame section of the apparatus frame 30 in the form of the transition section / transition segment 31, 32U and / or the connecting element 110, 120; 130, 140 is characterized by an arcuate outer contour 30K, which, each in this view, is arranged offset relative to the respective handle 81, 82.

[0152] As can be seen from the illustration in FIG. 1, the connecting elements 110, 120, 130, 140 are characterized relative to the apparatus frame 30, that is, the frame elements 31L and 32L, at least in the first direction R1 by a raised position and / or by a raised shape.

[0153] The connecting elements 110, 120, 130, 140 therefore contribute, among other things, that the apparatus frame 30 comprises a support profile 30AP on the outer side 30A5 in the first direction R1, in order to place the work apparatus 1, for example, on an essentially flat and / or essentially level ground B while forming a distance between the handles 81 and 82 and / or the drive unit 20 and the ground B. As a result, for example, a simplified replacement process of the working tool 10 in the form of the drilling tool 10 can be realized, in which damage to the handles 81, 82 and / or to the drive unit 20 is simultaneously prevented.

[0154] Each of the connecting elements 110, 120, 130, 140 comprises a mounting section 110M, 120M, 130M, 140M and a receiving section 110A, 120A, 130A, 140A. For the sake of simplicity, the connecting element 110 is described in more detail below, which applies accordingly to the other connecting elements 120, 130, and 140.

[0155] The mounting section 110M serves to fasten, in particular releasably fasten, the connecting element 110 to the frame section / frame element / frame segment in the form of the transition segment 310 and / or the longitudinal member 31L (see also the figures with the further embodiment of the work apparatus 1).

[0156] The receiving section 110A serves to fasten, in particular to releasably fasten, the frame element in the form of the cross member 31Q. The mounting section 110M and the receiving section 110A are formed and / or arranged offset in three directions R1, R2, R3 relative to each other in order to arrange the cross member 31Q, and in particular the handle 81 associated therewith, on the apparatus frame 30 in a defined location. As already described above, the three directions R1, R2, R3 represent, in particular, directions of the three-dimensional space, which are oriented, arranged and / or aligned perpendicular to each other.

[0157] For arrangement of the cross member 31Q in the defined location, the mounting section 100M and the receiving section 110A are formed and / or arranged at a distance from each other, in particular in the first direction R1, in particular parallel to the drive axis 20A of the drive unit 20.

[0158] The defined location comprises a protected, in particular a deformation-protected, position and / or alignment of the cross member 31Q and thus of the handle 81.

[0159] The connecting element 110 is arranged and / or formed on the apparatus frame 30 as a corner connecting element 110. The connecting element 110 is configured to at least partially shield, in particular to encase, the apparatus frame 30, in particular the transition segment 310 and / or the longitudinal member 31L, in at least one direction R1, R2, R3.

[0160] The mounting section 100M is configured to form a releasable, essentially form-fit and / or a releasable, essentially force-fit connection with the longitudinal member 31L and / or the transition segment 310. Due to its arcuate formation, the transition segment 31Ü is characterized by a direction-changing course.

[0161] The connecting element 110 is formed in multiple parts. The connecting element 110 comprises a first connecting part 111 and a second connecting part 112. The first connecting part 111 and the second connecting part 112 are each manufactured as separate individual part. The mounting section 110M is / will be formed by the first connecting part 111 and by the second connecting part 112.

[0162] The first connecting part 111 and the second connecting part 112 are connected to each other via a first screw connection and a second screw connection, which are not marked in detail in FIG. 1 for reasons of clarity. A screw of the respective screw connection penetrates the longitudinal member 31L at a defined point in the first direction R1. By connecting the first connecting part 111 to the second connecting part 112 by means of two screw connections, an operating torque occurring in an operating state of the work apparatus 1, that is the drilling apparatus 1, can be transmitted to the cross member 31Q in an improved manner.

[0163] The first connecting part 111 and the second connecting part 112 together with a section of the longitudinal member 31L form an essentially form-fit connection. By means of the two screw connections, an essentially force-fit connection with the longitudinal member 31L in the form of a clamping connection can be formed additionally. In other words, the first connecting part 111 and the second connecting part 112 serve to fasten the connecting element 110 to the longitudinal member 31L by forming a clamping connection with the longitudinal member 31L. The first connecting part 111 is described in more detail below with reference to FIG. 7.

[0164] The receiving section 110A is formed and / or arranged on the first connecting part 111. The receiving section 110A comprises two retaining segments 113, 114, which are spaced apart and / or arranged opposite each other to form a releasable, essentially form-fit connection and / or a releasable, essentially force-fit connection with a front segment 31QS of the cross member 31Q. Each of the retaining segments 113, 114 is formed shell-shaped and / or essentially complementary to an outer surface of the front segment 31QS of the cross member 31A.

[0165] In order to apply a preload force, in particular in the form of a clamping force, to the front segment 31QS, at least one of the retaining segments 113, 114 can be formed to be essentially reversibly deformable at least in sections. In order to fasten the front segment 31QS and thus the cross member 31Q to the receiving section 110A, a screw connection is formed between the retaining segments 113, 114, wherein a screw penetrates the front segment 31QS, in particular in the first direction R1. For reasons of clarity, the screw connection is not marked in detail in FIG. 1, but is graphically visible at the receiving section 120A of the connecting element 120.

[0166] The connecting element 110 or its components 111, 112, 113, 114 is formed in particular from an electrically insulating material with inherent electrical insulating properties and resulting insulating capabilities, or comprises at least one layer of an electrically insulating material. The electrically insulating material can be based on a plastic. This allows, for example, the cross member 31Q to be fastened to the connecting element 110 in an electrically insulated manner.

[0167] The connecting element 110 comprises the bearing unit 60, which is described below with reference to further figures.

[0168] FIG. 2 shows a second embodiment of the work apparatus 1, that is, the drilling apparatus 1, according to the present invention in a second state in a perspective view. The drilling apparatus 1 according to the second embodiment is formed and / or configured in sections similar to the drilling apparatus 1 of the first embodiment.

[0169] In addition to a drive unit 20 and a drive element 21 for coupling an interchangeable (replaceable) drilling tool 10, the drilling apparatus 1 comprises a apparatus frame 30 for receiving the drive unit 20, an actuator unit 40 for braking the drilling tool 10 and / or for switching off the drive unit 20 and / or for disconnecting a coupling between the drive unit 20 and the drilling tool 10, an operating element 50 for activating the actuator unit 40, a bearing unit 60 for bearing the operating element 50, and a retaining element 70 for retaining the operating element 50 in the parking location PL of the operating element 50.

[0170] In the illustration in FIG. 2, the operating element 50 is in a parking state and thus in a parking location PL, in which it is received at and supported by the retaining element 70. For reasons of clarity, the drilling tool 10 is hidden in FIG. 2 and the other FIGS. 3 to 5 of the second embodiment of the drilling apparatus 1.

[0171] In addition to the frame elements and / or frame sections 31Q, 32Q, 31L, 32L, 35Q, 36Q, the frame elements 33Q and 34Q are characterized as cross members of the apparatus frame 30. The frame elements 33Q and 34Q are part of a circumferential and closed subframe, which is connected to further frame elements of the apparatus frame 30 at coupling sections 31V, 32V, 33V, 34V (see also FIG. 3). The retaining element 70 is arranged on the frame element 33Q of the closed and circumferential subframe and not on the frame element 31Q in the form of the handle tube.

[0172] The frame elements 31Q, 32Q are releasably connected via the respective connecting elements 110, 120, 130, 140 and their respective receiving sections 110A, 120A, 130A, 140A and mounting sections 110M, 120M, 130M, 140M with the frame elements 31L and 32L as longitudinal members of the apparatus frame 30, whereby a plug connection and a screw connection are formed in each case.

[0173] The connecting elements 110, 120, 130, 140 are plugged onto respective front segments 31LS, 32LS of the longitudinal members 31L, 32L via their mounting sections 110M, 120M, 130M, 140M.

[0174] Each of the connecting elements 110, 120, 130, 140 comprises a functional structure 115, 125, 135, 145 for absorbing, transferring, and / or transmitting stress energy when subjected to an external stress, for example in the form of an impact. The functional structures 115, 125, 135, 145 extend in particular in and / or along the second direction R2. Thus, in defined situations of the drilling apparatus 1, the functional structures 115, 125, 135, 145 help to keep the operating element 50 protected in the parking state, that is, in a parking location PL.

[0175] In the illustration in FIG. 2, the operating element 50 is, for example, hooked onto the retaining element 70 in the parking state and is aligned and / or arranged essentially parallel to the frame element 31Q and / or to the frame element 33Q, wherein a spring force of a spring element of the bearing unit 60, which is not visible in FIG. 2, presses the operating element 50 in and / or along the second direction R2 against the retaining element 70.

[0176] From the illustration in FIG. 2, the respective offset of the mounting portion 110M, 120M and the receiving portion 110A, 120A relative to each other in the three directions R1, R2 and R3 can be seen, for example, on the basis of the formation of the connecting element 110 or 120. The respective formation of the connecting element 110, 120, 130, 140, which is accompanied by a respective arrangement of the cross members 31Q and 32Q and thus of the handles 81 and 82, allows, for example, a more compact design of the apparatus frame 30 to be achieved.

[0177] FIG. 3 shows the drilling apparatus 1 from FIG. 2 in a first state in a top view, that is, in a view in and / or along the first direction R1. In the first state of the drilling apparatus 1, the operating element 50 is in a standby state, which is characterized by the standby location BL of the operating element 50. The operating element 50 protrudes in sections from the apparatus frame 30 in and / or along the directions R2 and R3.

[0178] The location of the bearing unit 60 with the bearing housing 61 for the pivotable mounting of the operating element 50 is clearly visible. In the top view of the drilling apparatus 1, the bearing unit 60 and, in particular, the first pivot axis 60X (see also FIG. 2) are arranged within the apparatus frame 30, which already provides a protected arrangement of the bearing unit 60 in a respective direction R1, R2, R3, with associated protected bearing of the operating element 50.

[0179] FIG. 4 shows the drilling apparatus 1 from FIG. 2 in the second state in a top view. The operating element 50 is in the parking location PL, that is, it has been adjusted from the operating location BL to the parking location PL and is retained in this location by the retaining element 70.

[0180] In the top view of the drilling apparatus 1, the operating element 50 extends in the state of the parking location PL, that is in the parking state, from the first frame side profile 31SP essentially parallel to the frame element 31Q and / or to the frame element 33Q toward the second frame side profile 32SP and ends within the apparatus frame 30, in particular in and / or along the third direction R3. In other words, in the top view of the drilling apparatus 1, the operating element 50 is arranged in the state of the parking location PL in and / or along the third direction R3 within the apparatus frame 30 in order to keep the operating element 50 protected by the apparatus frame 30.

[0181] In and / or along the second direction R2, the operating element 50 is also arranged within the apparatus frame 30 in the state of the parking location PL in order to keep the operating element 50 protected by the apparatus frame 30.

[0182] The operating element 50 can therefore be kept protected in the event of an external stress acting on the drilling apparatus 1 and in particular on the apparatus frame 30, thereby preventing damage to the operating element 50, for example. By the adjustable arrangement of the operating element 50 from the operating state and thus from the operating location BL into the parking state and thus into the parking location PL, an improved transport process of the drilling apparatus 1 can furthermore be ensured, for example.

[0183] In other words, the operating element 50 of the drilling apparatus 1 according to the present invention is characterized by an extended pivot angle range in order to be able to pivot the operating element 50 into a transport position. The operating element 50 can, for example, be pivotably mounted on the apparatus frame 30 in a pivot angle range of at least 70°. Alternatively, other pivot angle ranges are also conceivable. The apparatus frame 30 can form a stop for the operating element 50, which limits the pivot angle range of the operating element 50. In particular, the operating element 50 can be mounted and formed on the drilling apparatus 1 in such a way that the operating element 50 does not protrude above and / or out of the apparatus frame 30 in the transport position, for example.

[0184] In the view in the first direction R1, that is, in the top view of the work apparatus 1, that is, the drilling apparatus 1, the handle 81 forms a minimum distance D12 in the second direction R2 to a definable and / or idealized boundary line GL1, which serves to define a maximum dimension of the apparatus frame 30 in the second direction R2.

[0185] Corresponding to the handle 81, the handle 82 forms, in the second direction R2, a minimum distance D22 to a definable and / or idealized boundary line GL2, which serves to define a maximum dimension of the apparatus frame 30 in the second direction R2.

[0186] FIG. 5 shows the drilling apparatus 1 from FIG. 2 in the second state in a side view, that is, in a view in and / or along the second direction R2.

[0187] The arrangement of the bearing unit 60 of the operating element 50 within the apparatus frame 30 and the alignment of the first pivot axis 60X can be seen. In this view, the operating element 50 is arranged in the parking location PL within the apparatus frame 30 and is in turn kept protected by the apparatus frame 30.

[0188] In the view in the second direction R2, that is, in the side view of the work apparatus 1, that is, the drilling apparatus 1, the handle 81 and the handle 82 each form, in the first direction R1, a minimum distance to a definable and / or idealized boundary line GL3, which serves to define a maximum dimension of the apparatus frame 30 in the first direction R1, of which the minimum distance D21 of the handle 82 is visible and marked in FIG. 5.

[0189] The minimum distance D12 and / or D22 (see FIGS. 3 and 4) is each greater than the minimum distance D21. Alternatively, the opposite can also be the case, whereby the minimum distance D21 is greater than the minimum distance D12 and / or D22.

[0190] FIG. 6 shows an enlarged section of the work apparatus 1, that is, the drilling apparatus 1, from FIG. 2.

[0191] The fastening of the connecting element 120 to the longitudinal member 32L is realized by means of the mounting portion 120M of the connecting element 120 and by means of the front segment 32LS of the longitudinal member 32, wherein the formation of a screw connection is furthermore employed.

[0192] The fastening of the cross member 31Q via the front segment 31QS to the mounting section 120A of the connecting element 120 is also clearly visible, whereby a screw connection is also formed.

[0193] The mounting section 120M and the receiving section 120A are formed and / or arranged offset relative to each other in the three directions R1, R2, and R3, whereby the cross member 31Q and / or the handle 81 can be arranged in the defined, in particular offset, location.

[0194] The functional structure 125 for absorbing, distributing, and / or transmitting a stress energy when subjected to an external stress comprises several deformation zones in the form of chambers, which are arranged adjacent to each other and / or in a row. The chambers are connected to each other via respective wall sections of the connecting element 120.

[0195] The connecting element 120 is characterized above all by a relatively compact design. The connecting element 120 is, in particular, manufactured integrally in one piece and / or without forming, in particular by at least one of the following processes: an injection process, a casting process, a sintering process, a 3D printing process, a shrinkage process, a curing process. The connecting element 120 can be manufactured in particular by an injection molding process. The same applies to the other connecting elements 110, 130, and 140 of the work apparatus 1 from FIG. 2.

[0196] FIG. 7 shows the first connecting part 111 of the connecting element 110 of the work apparatus 1 from FIG. 1.

[0197] The first connecting part 111 comprises a channel 116 for contacting a first outer side of the longitudinal member 31L and / or the transition segment 31Ü, that is, a respective outer surface. The channel 116 is formed at least in sections essentially complementary to the first outer side of the longitudinal member 31L and / or the transition segment 31Ü.

[0198] Five contact ribs 117 are arranged one behind the other within the channel 116. The respective contact front faces of the contact ribs 117 are formed essentially complementary to the first outer surface of the longitudinal member 31L and / or the transition segment 31U in order to contact the longitudinal member 31L and / or the transition segment 310 at defined points in an assembly state and thus to fasten the connecting element 110 to the longitudinal member 31L.

[0199] The receiving section 110A for fastening the front segment 31QS of the cross member 31Q is also clearly visible. The receiving section 110A is formed on the first connecting part 111 and comprises the retaining segments 113, 114. The retaining segments 113, 114 are formed shell-shaped. The retaining segments 113, 114 are arranged spaced apart from each other and / or opposite each other.

[0200] As can be seen from the illustration in FIG. 7, the connecting element 110 comprises the bearing unit 60 with the bearing housing 61. The bearing unit 60 is configured to movably support the operating element 50. In particular, the bearing unit 60 is configured to pivotably support the operating element 50 so that it can pivot about the pivot axis 60X between the standby state, that is, the standby location BL, and the parking state, that is, the parking location PL. The bearing housing 61 can be an integral, one-piece component of the connecting element 110, in particular of the first connecting part 111.

[0201] The connecting element 110 and, in this case, the first connecting part 111 is formed and / or configured to arrange the bearing unit 60 with each an offset in relation to the apparatus frame 30, in particular to the cross member 31Q (not shown in FIG. 7), in at least one direction R1, R2, R3, in particular within the inner area 301 of the apparatus frame 30 (see also FIG. 1).

[0202] At least one reinforcing element 118 can each be formed and arranged between the receiving section 110A and / or the first connecting part 111 and / or the bearing housing 61 in order to stiffen the connecting element 110, that is the first connecting part 111, in at least one direction R1, R2, R3. The reinforcing element 118 can, for example, be formed as a rib or as a lamella.

[0203] A switching unit 150 is arranged on the at least one connecting element 110, in particular on a side opposite the bearing unit 60. In other words, the connecting element 110 comprises a switching unit 150.

[0204] The switching unit 150 is formed in particular as an electromechanical switching unit 150. The switching unit 150 is coupled to the bearing unit 60 and configured to close or interrupt a circuit for activating the actuator unit 40 of the work apparatus 1 when the operating element 50 is operated in the standby state.

[0205] The operating element 50 can be configured in the standby state by operating the switching unit 150 to activate the drilling apparatus 1, in which the drilling apparatus 1 is in an operational state. In addition or alternatively, the operating element 50 can be configured in the parking state by operating the switching unit 150 to deactivate the drilling apparatus 1, in which the drilling apparatus 1 is in a transportable state.

[0206] FIG. 8 shows, for further illustration, an enlarged section of the work apparatus 1 from FIG. 1 in a perspective view, wherein the operating element 50 is shown decoupled from the bearing unit 60. In addition, a housing part of the bearing unit 60 is hidden for reasons of clarity.

[0207] The arrangement of the bearing unit 60 of the operating element 50, which is offset inwards toward the inner area 301 relative to the outer sides 30A1 and 30A3 by the connecting element 110, is clearly visible, whereby the bearing unit 60 can be kept protected by the apparatus frame 30.

[0208] Furthermore, the illustration in FIG. 8 shows the fastening of the operating element 50 to a rotary guide (rotary body) of the bearing unit 60 by means of screw connections, which are not marked in detail and / or are partially hidden for reasons of clarity.

[0209] FIG. 9 shows an enlarged section of the work apparatus 1 from FIG. 1 in a perspective view, whereby some elements of the bearing unit 60 are hidden and / or indicated by dashed lines.

[0210] As can be seen from the illustration in FIG. 9, an applying element 190 is arranged on the connecting element 110, or the connecting element 110 comprises an applying element 190. The applying element 190 is configured, in particular at least in the standby state, to apply a preload force to the operating element 50 in order to retain the operating element 50, in particular to retain it in the standby state. The preload force can be a defined compressive force.

[0211] In the present embodiment, the applying element 190 is formed as a spring element, in particular as a coil spring element. The applying element 190 is arranged or received within the bearing unit 60, that is within a housing part of the bearing housing 61, and is guided along the pivot axis 60X. For this purpose, the housing part of the bearing housing 61 extends along the pivot axis in the form of a hollow cylinder in order to receive the applying element 190 therein.

[0212] The applying element 190 can be supported on the bearing unit 60. Alternatively, the applying element 190 can be supported on a frame element / frame section / frame segment of the apparatus frame 30.

[0213] The switching unit 150 is connected to the bearing unit 60, in particular to the applying element 190 for applying the preload force to the operating element 50, in a force-decoupled manner. The switching unit 150 can be formed as a rotary cam switching unit for this purpose.

[0214] FIG. 10 shows a further enlarged section of the work apparatus 1 from FIG. 1 in a further perspective view, in particular essentially in the first direction R1 and thus in a perspective top view.

[0215] A housing part of the switching unit 150 in the form of a cover is hidden so that further elements of the switching unit 150 are visible, which, however, are not marked in detail.

[0216] FIG. 10 clearly shows, among other things, that the switching unit 150 is also arranged within the apparatus frame 30 and thus within the inner area 301 of the apparatus frame 30, particularly in a top view of the work apparatus 1.

[0217] The formation or configuration of the connecting element 110, which in particular comprises the switching unit 150 and / or the bearing unit 60, or on which in particular the switching unit 150 and / or the bearing unit 60 are arranged, can, for example, avoid the need for a further (separate) mounting part for supporting the switching unit 150 and / or the bearing unit 60, which also characterizes the work apparatus 1 of the present invention.

[0218] By the present invention, in particular a work apparatus 1 can be provided which is further improved with respect to functionality and design. Furthermore, in particular an improved protection of respective elements and / or units can be ensured.

[0219] The present invention is not limited to the embodiments described above. Rather, a variety of variants and modifications are possible which also make use of the inventive concept and therefore fall within the scope of protection. In particular, the present invention also claims protection for the subject matter and features of the dependent claims independently of the claims referred to.LIST OF REFERENCE SIGNS1 work apparatus, drilling apparatus

[0112] The following detailed description of the embodiments shown in the figures serves to provide further illustration or clarification and is not intended to limit the scope of the present invention in any way.DETAILED DESCRIPTION

[0113] FIG. 1 shows a first embodiment of the work apparatus 1 according to the present invention in the form of a drilling apparatus 1 in a first state in a perspective view. The work apparatus 1 can alternatively be formed, for example, as a stirring apparatus 1, a trimming apparatus 1, or a ramming apparatus 1.

[0114] The drilling device 1 according to the present invention is a mobile, hand-held, hand-guided, hand-operated and / or hand-portable drilling device 1 for generating a drill hole L in a ground B. For simplicity, only the term “drilling apparatus” will be used hereinafter. The ground B can be, for example, the ground B of a garden, a park, a sports facility, a construction site, an agricultural area, or a forestry area. In other words, the drilling apparatus 1 can be formed as an earth auger.

[0115] In order to create the drill hole L, the drilling apparatus 1 comprises a drilling tool 10 for processing the ground B. The drilling tool 10 can be formed as a drilling tool 10 known from the prior art for generating a drill hole L in ground B and can comprise, for example, a drill head with a cutter and a screw conveyor. The drilling tool 10 can be formed as an interchangeable (replaceable) drilling tool 10.

[0116] The drilling apparatus 1 comprises a drive unit 20. The drive unit 20 comprises an electric motor with a stator and a rotor. The rotor serves as a drive shaft for transmitting a generated torque. The electric motor is supplied with electrical energy, in particular in an operating state of the drilling apparatus 1, by an electrical energy supply device in the form of an interchangeable accumulator. In other words, the drilling apparatus 1 is a drilling apparatus 1 that can be operated autonomously (independently) from a stationary energy source. For reasons of clarity, the electric motor and the energy supply device are not shown in detail in the figures. Alternatively, it is possible for the drive unit 20 to be formed as a combustion engine drive unit 20, which comprises a fuel tank

[0117] A control element 823 on the handle 82 serves for adjusting, in particular for controlling, the power of the drive unit 20, in particular in conjunction with a locking element 822 for blocking and / or releasing the control element 823. The control element 823 can, for example, be configured in the form of a lever. The control element 823 is connected to a power control element (power electronics) of the electric motor.

[0118] The drilling apparatus 1 comprises a drive element 21 to which the drilling tool 10 can be releasably and / or interchangeably mounted, for example by means of a plug connection and a safety plug. The drive element 21 can be formed as a drive pinion with a tooth profile (drill spindle). The drive element 21 can be a direct (immediate) component or, in particular, a section of the rotor. Alternatively, the drive element 21 can be connected to the rotor via a coupling by means of a coupling drum and / or via a gearbox. The drive unit 20 can be coupled to the drilling tool 10 via the drive element 21 in order to drive the drilling tool 10 in a mounted and / or coupled state.

[0119] The location of the drive unit 20 and, in particular, of the rotor can be characterized by a drive axis 20X along which the rotor extends and / or around which the rotor rotates. Depending on the location of the drive unit 20, the drive axis 20X can be arranged essentially parallel or essentially perpendicular to a tool axis 10X of the drilling tool 10, along which the drilling tool 10 extends.

[0120] The drilling apparatus 1 comprises an apparatus frame 30. The apparatus frame 30 serves, among other things, to receive, that is, to arrange the drive unit 20 and to handle (operate), in particular guide, the drilling apparatus 1 by a user.

[0121] The apparatus frame 30 extends in and / or along a respective direction R1, R2, R3 differently. The directions R1, R2, and R3 represent, in particular, directions of the three-dimensional space, which are arranged and / or aligned perpendicular to each other. The first direction R1 can be arranged parallel to the drive axis 20X.

[0122] The apparatus frame 30 is characterized and / or defined in and / or along the first direction R1 by two outer sides, of which the outer sides 30A5 and 30A6 are marked in FIG. 1. The outer side 30A5 represents an upper side of the drilling apparatus 1, and the outer side 30A6 represents a lower side of the drilling apparatus 1, which, when the drilling tool 10 is hidden, is defined, among other things, by the drive element 21.

[0123] In and / or along the second direction R2, the apparatus frame 30 is characterized and / or defined by the outer sides 30A3 and 30A4. In and / or along the third direction R3, the apparatus frame 30 is characterized and / or defined by the outer sides 30A1 and 30A2. The extension of the apparatus frame 30 in the second direction R2 is greater than the extension of the apparatus frame 30 in the first direction R1 and than the extension of the apparatus frame 30 in the third direction R3. With regard to the apparatus frame 30 and / or the drilling apparatus 1 (as a whole), the first direction R1 can represent a vertical direction, the second direction R2 a longitudinal direction, and the third direction R3 a transverse direction, along each of which the apparatus frame 30 and / or the drilling apparatus 1 as a whole extends.

[0124] The apparatus frame 30 can, for example, be formed as a self-contained frame and / or as a cage-shaped frame. The apparatus frame 30 can be formed as a circumferential apparatus frame 30 in at least one view in at least one direction R1, R2, R3. The apparatus frame 30 comprises frame elements and / or frame sections which are formed, among other things or essentially, by tubes, tube segments and / or tube connections with essentially annular-shaped profiles, and of which the frame elements, frame segments and / or frame sections 31Q, 32Q, 35Q, 36Q are marked as cross members, 31L and 32L as longitudinal members, and 31U and 32U as transition sections / transition segments.

[0125] For the arrangement, in particular for the releasable fastening, of the frame elements 31Q and 32Q at defined positions of the apparatus frame 30, the connecting elements 110, 120, 130, 140 are provided, which connecting elements can be formed in one piece or in multiple parts. The frame elements 31Q and 32Q each comprise a handle 81 and 82 and therefore represent so-called handle tubes.

[0126] The drive unit 20 can be arranged completely (as a whole) within the apparatus frame 30, that is, within an inner area 301 of the apparatus frame 30, for example on a mounting plate of the apparatus frame 30. Alternatively, it is possible that the drive unit 20 is arranged at least partially within the apparatus frame 30 and thus protrudes in sections from the apparatus frame 30 in at least one direction R1, R2, R3.

[0127] The drilling apparatus 1 comprises an actuator unit 40. Depending on the respective configuration of the drilling apparatus 1, the actuator unit 40 can be configured for braking the drilling tool 10 and / or the drive unit 20, for switching off the drive unit 20 and / or for disconnecting a coupling between the drive unit 20 and the drilling tool 10. In the embodiment of the drilling apparatus 1 shown in FIG. 1, the actuator unit 40 is formed, for example, as a clutch and couples the rotor of the electric motor to the drive element 21. The clutch can be formed as a releasable and / or switchable clutch.

[0128] In other words, the actuator unit 40 serves to adjust the operation and / or the drive of the drilling apparatus 10 and / or the drive unit 20 in defined situations and / or operating states of the drilling apparatus 1, in particular within a defined period of time from the occurrence and / or detection (sensing) of an occurrence of an event. An adjustment of the operation and / or the drive of the drilling tool 10 and / or the drive unit 20 is made, for example, in the event, in which the drilling tool 10 suddenly gets caught and / or blocked in the ground B and is thus abruptly slowed down by components of the ground B, such as roots or stones, which in turn initiates a twisting of the drive unit 20 and thus of the apparatus frame 30 around the drive axis 20X.

[0129] The drilling apparatus 1 comprises an operating element 50. The operating element 50 serves for activating the actuator unit 40, in particular as a result of detecting (sensing) a twisting of the apparatus frame 30 and / or as a result of the operating element 50 coming into contact with the user. The detection of a twist can be realized, for example, with an angle sensor or with an inertia sensor, in particular in the form of an acceleration sensor. The operating element 50 can be formed in the form of an operable lever, bracket, arm, pedal, or as an operable rod. In the drilling apparatus 1 in FIG. 1, the operating element 50 is formed in the form of a so-called trigger lever, which extends in and / or along a longitudinal direction 50L of the operating element 50. The operating element 50 can be formed in sections in the form of a tube with an essentially annular cross-section.

[0130] According to the invention, the operating element 50 of the drilling apparatus 1 can be adjustably arranged between a standby state and a parking state, in order to keep the operating element 50 at least partially protected by the apparatus frame 30 in the parking state, in particular in at least one direction R1, R2, R3.

[0131] To adjust the parking state, which is characterized by a parking location PL, the operating element 50 is movably mounted on the first frame side profile 31SP. The operating element 50 is pivotably mounted on the first frame side profile 31SP, in particular by means of a bearing unit 60 with a bearing housing 61, about a first pivot axis 60X. The first pivot axis 60X can be arranged and / or aligned essentially parallel to the drive axis 20X. Alternatively, it is possible that the operating element 50 is pivotably mounted about a first pivot axis 60X on the drive unit 20 by means of a bearing unit 60.

[0132] The bearing unit 60 can be formed as a bearing unit 60 that can be operated manually via the operating element 50. Alternatively or additionally, the bearing unit 60 can be formed as an automated motor-driven bearing unit in order to adjust the operating element 50 from the standby state to the parking state and / or from the parking state to the standby state. The operating element 50 comprises a spring element 90 or is coupled to the bearing unit 60 via a spring element 90 in the form of a coil spring. The spring element 90 extends essentially in and / or along the longitudinal direction 50L, thereby realizing the operating element 50 to pivot about a second pivot axis 90X. The first pivot axis 60X and the second pivot axis 90X are arranged and / or aligned differently to each other, in particular essentially perpendicular to each other.

[0133] The standby state of the operating element 50 is, in particular, a state in which the operating element 50 is arranged in a defined location relative to the drive unit 20 and / or the apparatus frame 30 in order to activate the actuator unit 40. The standby state of the operating element 50 can be a prerequisite for an operational state of the drilling apparatus 1. In FIG. 1, the operating element 50 is in the standby state, which comprises a standby location BL of the operating element 50 and / or which is characterized by a standby location BL of the operating element 50. In the standby location BL, the operating element 50 protrudes in sections from the apparatus frame 30 in a view in the first direction R1, in particular in a top view of the drilling apparatus 1. In addition, reference is made to the top view in FIG. 3 in connection with a second embodiment of the drilling apparatus 1, which also shows the operating element 50 in a standby state, which is characterized by the arrangement of the operating element 50 in a standby location BL.

[0134] The parking state is, in particular, a state in which the operating element 50 is in a parking location PL, in particular relative to and / or on the apparatus frame 30, in order to be kept at least partially protected by the apparatus frame 30 in at least one direction R1, R2, R3, for example when subjected to an external stress in the form of an impact. The adjustable arrangement of the operating element 50 in a parking location PL provides, for example, improved transportability of the drilling apparatus 1. In FIG. 1, the operating element 50 in the parking location PL is shown and marked with a dashed line. The parking state can therefore comprise or characterize a transport state of the operating element 50, in which the operating element 50 is in a parking location PL, so that the drilling apparatus 1 can be transported more easily in the course of a transport process.

[0135] Both the standby location BL and the parking location PL can each be characterized by a defined position and / or by a defined alignment of the operating element 50, in particular relative to the apparatus frame 30, the actuator unit 40, and / or the drive unit 20.

[0136] The apparatus frame 30 comprises a first frame side profile 31SP and a second frame side profile 32SP, which are arranged opposite each other and spaced apart from each other in the third direction R3, and which each define the outer side 30A1 and 30A2 of the apparatus frame 30 in the third direction R3.

[0137] The operating element 50 can be subjected to a preload force by the bearing unit 60, for example, in order to be pressed against a frame section of the apparatus frame 30 with a defined force in the standby state and thus in the standby location BL. The frame section thus acts as a stop for the operating element 50 and, in the first embodiment of the drilling apparatus 1, is formed by the transition section / transition segment 31Ü.

[0138] The drilling apparatus 1 comprises a retaining element 70 for locking the operating element 50 in the parking state, that is, in the parking location PL. The retaining element 70 is arranged on the apparatus frame 30, in particular on the cross member 31Q, and is formed to retain the operating element 50 in the parking location PL in the first direction R1 and / or in the second direction R2, supporting the preload force applied to the operating element 50.

[0139] The retaining element 70 can, for example, be formed in the form of a bracket, a clamp or a hook. In addition or alternatively, the retaining element 70 can be formed to be essentially dimensionally stable in sections and / or dimensionally variable in sections. For example, a section of the retaining element 70 can be formed to be essentially reversibly deformable in order to ensure a certain degree of flexibility in the course of the adjustment of the operating element 50 into the parking location PL. In the parking state and thus in the parking location PL, the operating element 50 and the retaining element 70 form a releasable, essentially form-fit retaining connection and / or a releasable, essentially force-fit, in particular a friction-locking, retaining connection. The retaining connection 50, 70 can comprise at least one of the following or be formed as at least one of the following retaining connections: a hook-in connection, a plug-in connection, a snap-in connection, a clamping connection.

[0140] In the parking state and thus in the parking location PL, the operating element 50 is kept protected by the apparatus frame 30 in the three directions R1, R2, R3 and, in particular, is shielded in sections by the apparatus frame 30 in the third direction R3 on the outer side 30A2.

[0141] The parking location PL represents in particular a location and thus a position and / or an alignment in which the operating element 50 is essentially within the apparatus frame 30 and is at least partially spaced apart from frame profiles 30A1, 30A2, 30A3, 30A4, 30A5, 30A6, which each define an outer side of the apparatus frame 30, in order to ensure a protection of the operating element 50 by the apparatus frame 30.

[0142] In a further embodiment of the drilling apparatus 1, the parking state can also comprise a parking location PL in which, depending on the configuration of the operating element 50, among other things, the operating element 50 is kept at least partially protected by the apparatus frame 30, but protrudes from the apparatus frame 30 in at least one direction R1, R2, R3. The parking state can comprise a parking location PL of the operating element 50 in which the operating element 50 protrudes in sections from the apparatus frame 30 in a view in the first direction R1, in particular in a top view of the work apparatus 1, that is the drilling apparatus 1, by a maximum of 20 percent of the total length of the operating element 50 along the longitudinal direction 50L of the operating element 50.

[0143] As already explained, the apparatus frame 30 comprises a first handle 81 and a second handle 82 for handling the drilling apparatus 1 by a user.

[0144] The first handle 81 is arranged between the first frame side profile 31SP and the second frame side profile 32SP on the frame element 32Q, that is on the cross member 31Q, and the second handle 81 is arranged between the first frame side profile 31SP and the second frame side profile 32SP on the frame element 32Q, that is on the cross member 32Q.

[0145] Both the first handle 81 and the second handle 82 are arranged offset in the first direction R1, in particular essentially parallel to the drive axis 20X of the drive unit 20, relative to the frame sections of the apparatus frame 30 in the form of the frame elements 31L and 32L, which each represent longitudinal members of the apparatus frame 30, and relative to the frame sections of the apparatus frame 30 in the form of the transition sections / transition segments 310 and 320 with an offset in the second direction R2 in order to keep the first handle 81 and the second handle 82 essentially protected in the respective direction R1, R2.

[0146] In a view in the second direction R2, in particular in a side view of the work apparatus 1, that is the drilling apparatus 1, the handle 81 and the handle 82 are arranged offset in the first direction R1 inwards toward the inner area 301 of the apparatus frame 30, in particular toward the drive unit 20.

[0147] The first handle 81 is also arranged relative to the frame sections of the apparatus frame 30 in the form of connecting elements 110 and 120, each with an offset in the first and second direction R1, R2. The same applies to the second handle 82 with regard to the connecting elements 130 and 140. The connecting elements 110, 120, 130, 140 represent front sections of the apparatus frame 30, which each define at least partially an outer side 30A1, 30A2, 30A3, 30A4, 30A5 of the apparatus frame 30 in the respective direction R1, R2, R3.

[0148] The frame elements 31L, 32L, 31Q, 32Q of the apparatus frame 30 also serve, among other things, to receive and / or transmit at least part of a stress energy when subjected to external stress. The external stress can be caused, for example, by a tipping event of the work apparatus 1, that is, the drilling apparatus 1. This allows the handles 81, 82 to be kept essentially free of stress in at least one direction R1, R2, R3.

[0149] The cross member 31Q is connected to the frame elements / frame sections / frame segments 31L, 31Ü and 32L, 32U via the connecting elements 110 and 120, that is it is fastened to the frame sections / frame segments 31L, 31Ü and 32L, 32Ü. The same applies to the cross member 32Q in conjunction with the connecting elements 130 and 140. In other words, the apparatus frame 30 comprises a first cross member 31Q for the offset arrangement of the first handle 81 and a second cross member 32Q for the offset arrangement of the second handle 82.

[0150] A maximum distance D82 (see also FIGS. 3 and 4) between the first cross member 31Q and the second cross member 32Q, in particular between the first handle 81 and the second handle 82, in the second direction R2 is smaller than a distance between the opposite front faces 31SF and 32SF of the apparatus frame 30 in the second direction R2 (see also FIGS. 3 and 4).

[0151] As can also be seen from the illustration in FIG. 1, in a view in the longitudinal direction 81L, 82L of the respective handle 81, 82, which is parallel to the third direction R3, the respective frame section of the apparatus frame 30 in the form of the transition section / transition segment 31, 32U and / or the connecting element 110, 120; 130, 140 is characterized by an arcuate outer contour 30K, which, each in this view, is arranged offset relative to the respective handle 81, 82.

[0152] As can be seen from the illustration in FIG. 1, the connecting elements 110, 120, 130, 140 are characterized relative to the apparatus frame 30, that is, the frame elements 31L and 32L, at least in the first direction R1 by a raised position and / or by a raised shape.

[0153] The connecting elements 110, 120, 130, 140 therefore contribute, among other things, that the apparatus frame 30 comprises a support profile 30AP on the outer side 30A5 in the first direction R1, in order to place the work apparatus 1, for example, on an essentially flat and / or essentially level ground B while forming a distance between the handles 81 and 82 and / or the drive unit 20 and the ground B. As a result, for example, a simplified replacement process of the working tool 10 in the form of the drilling tool 10 can be realized, in which damage to the handles 81, 82 and / or to the drive unit 20 is simultaneously prevented.

[0154] Each of the connecting elements 110, 120, 130, 140 comprises a mounting section 110M, 120M, 130M, 140M and a receiving section 110A, 120A, 130A, 140A. For the sake of simplicity, the connecting element 110 is described in more detail below, which applies accordingly to the other connecting elements 120, 130, and 140.

[0155] The mounting section 110M serves to fasten, in particular releasably fasten, the connecting element 110 to the frame section / frame element / frame segment in the form of the transition segment 310 and / or the longitudinal member 31L (see also the figures with the further embodiment of the work apparatus 1).

[0156] The receiving section 110A serves to fasten, in particular to releasably fasten, the frame element in the form of the cross member 31Q. The mounting section 110M and the receiving section 110A are formed and / or arranged offset in three directions R1, R2, R3 relative to each other in order to arrange the cross member 31Q, and in particular the handle 81 associated therewith, on the apparatus frame 30 in a defined location. As already described above, the three directions R1, R2, R3 represent, in particular, directions of the three-dimensional space, which are oriented, arranged and / or aligned perpendicular to each other.

[0157] For arrangement of the cross member 31Q in the defined location, the mounting section 100M and the receiving section 110A are formed and / or arranged at a distance from each other, in particular in the first direction R1, in particular parallel to the drive axis 20A of the drive unit 20.

[0158] The defined location comprises a protected, in particular a deformation-protected, position and / or alignment of the cross member 31Q and thus of the handle 81.

[0159] The connecting element 110 is arranged and / or formed on the apparatus frame 30 as a corner connecting element 110. The connecting element 110 is configured to at least partially shield, in particular to encase, the apparatus frame 30, in particular the transition segment 310 and / or the longitudinal member 31L, in at least one direction R1, R2, R3.

[0160] The mounting section 100M is configured to form a releasable, essentially form-fit and / or a releasable, essentially force-fit connection with the longitudinal member 31L and / or the transition segment 310. Due to its arcuate formation, the transition segment 31Ü is characterized by a direction-changing course.

[0161] The connecting element 110 is formed in multiple parts. The connecting element 110 comprises a first connecting part 111 and a second connecting part 112. The first connecting part 111 and the second connecting part 112 are each manufactured as separate individual part. The mounting section 110M is / will be formed by the first connecting part 111 and by the second connecting part 112.

[0162] The first connecting part 111 and the second connecting part 112 are connected to each other via a first screw connection and a second screw connection, which are not marked in detail in FIG. 1 for reasons of clarity. A screw of the respective screw connection penetrates the longitudinal member 31L at a defined point in the first direction R1. By connecting the first connecting part 111 to the second connecting part 112 by means of two screw connections, an operating torque occurring in an operating state of the work apparatus 1, that is the drilling apparatus 1, can be transmitted to the cross member 31Q in an improved manner.

[0163] The first connecting part 111 and the second connecting part 112 together with a section of the longitudinal member 31L form an essentially form-fit connection. By means of the two screw connections, an essentially force-fit connection with the longitudinal member 31L in the form of a clamping connection can be formed additionally. In other words, the first connecting part 111 and the second connecting part 112 serve to fasten the connecting element 110 to the longitudinal member 31L by forming a clamping connection with the longitudinal member 31L. The first connecting part 111 is described in more detail below with reference to FIG. 7.

[0164] The receiving section 110A is formed and / or arranged on the first connecting part 111. The receiving section 110A comprises two retaining segments 113, 114, which are spaced apart and / or arranged opposite each other to form a releasable, essentially form-fit connection and / or a releasable, essentially force-fit connection with a front segment 31QS of the cross member 31Q. Each of the retaining segments 113, 114 is formed shell-shaped and / or essentially complementary to an outer surface of the front segment 31QS of the cross member 31A.

[0165] In order to apply a preload force, in particular in the form of a clamping force, to the front segment 31QS, at least one of the retaining segments 113, 114 can be formed to be essentially reversibly deformable at least in sections. In order to fasten the front segment 31QS and thus the cross member 31Q to the receiving section 110A, a screw connection is formed between the retaining segments 113, 114, wherein a screw penetrates the front segment 31QS, in particular in the first direction R1. For reasons of clarity, the screw connection is not marked in detail in FIG. 1, but is graphically visible at the receiving section 120A of the connecting element 120.

[0166] The connecting element 110 or its components 111, 112, 113, 114 is formed in particular from an electrically insulating material with inherent electrical insulating properties and resulting insulating capabilities, or comprises at least one layer of an electrically insulating material. The electrically insulating material can be based on a plastic. This allows, for example, the cross member 31Q to be fastened to the connecting element 110 in an electrically insulated manner.

[0167] The connecting element 110 comprises the bearing unit 60, which is described below with reference to further figures.

[0168] FIG. 2 shows a second embodiment of the work apparatus 1, that is, the drilling apparatus 1, according to the present invention in a second state in a perspective view. The drilling apparatus 1 according to the second embodiment is formed and / or configured in sections similar to the drilling apparatus 1 of the first embodiment.

[0169] In addition to a drive unit 20 and a drive element 21 for coupling an interchangeable (replaceable) drilling tool 10, the drilling apparatus 1 comprises a apparatus frame 30 for receiving the drive unit 20, an actuator unit 40 for braking the drilling tool 10 and / or for switching off the drive unit 20 and / or for disconnecting a coupling between the drive unit 20 and the drilling tool 10, an operating element 50 for activating the actuator unit 40, a bearing unit 60 for bearing the operating element 50, and a retaining element 70 for retaining the operating element 50 in the parking location PL of the operating element 50.

[0170] In the illustration in FIG. 2, the operating element 50 is in a parking state and thus in a parking location PL, in which it is received at and supported by the retaining element 70. For reasons of clarity, the drilling tool 10 is hidden in FIG. 2 and the other FIGS. 3 to 5 of the second embodiment of the drilling apparatus 1.

[0171] In addition to the frame elements and / or frame sections 31Q, 32Q, 31L, 32L, 35Q, 36Q, the frame elements 33Q and 34Q are characterized as cross members of the apparatus frame 30. The frame elements 33Q and 34Q are part of a circumferential and closed subframe, which is connected to further frame elements of the apparatus frame 30 at coupling sections 31V, 32V, 33V, 34V (see also FIG. 3). The retaining element 70 is arranged on the frame element 33Q of the closed and circumferential subframe and not on the frame element 31Q in the form of the handle tube.

[0172] The frame elements 31Q, 32Q are releasably connected via the respective connecting elements 110, 120, 130, 140 and their respective receiving sections 110A, 120A, 130A, 140A and mounting sections 110M, 120M, 130M, 140M with the frame elements 31L and 32L as longitudinal members of the apparatus frame 30, whereby a plug connection and a screw connection are formed in each case.

[0173] The connecting elements 110, 120, 130, 140 are plugged onto respective front segments 31LS, 32LS of the longitudinal members 31L, 32L via their mounting sections 110M, 120M, 130M, 140M.

[0174] Each of the connecting elements 110, 120, 130, 140 comprises a functional structure 115, 125, 135, 145 for absorbing, transferring, and / or transmitting stress energy when subjected to an external stress, for example in the form of an impact. The functional structures 115, 125, 135, 145 extend in particular in and / or along the second direction R2. Thus, in defined situations of the drilling apparatus 1, the functional structures 115, 125, 135, 145 help to keep the operating element 50 protected in the parking state, that is, in a parking location PL.

[0175] In the illustration in FIG. 2, the operating element 50 is, for example, hooked onto the retaining element 70 in the parking state and is aligned and / or arranged essentially parallel to the frame element 31Q and / or to the frame element 33Q, wherein a spring force of a spring element of the bearing unit 60, which is not visible in FIG. 2, presses the operating element 50 in and / or along the second direction R2 against the retaining element 70.

[0176] From the illustration in FIG. 2, the respective offset of the mounting portion 110M, 120M and the receiving portion 110A, 120A relative to each other in the three directions R1, R2 and R3 can be seen, for example, on the basis of the formation of the connecting element 110 or 120. The respective formation of the connecting element 110, 120, 130, 140, which is accompanied by a respective arrangement of the cross members 31Q and 32Q and thus of the handles 81 and 82, allows, for example, a more compact design of the apparatus frame 30 to be achieved.

[0177] FIG. 3 shows the drilling apparatus 1 from FIG. 2 in a first state in a top view, that is, in a view in and / or along the first direction R1. In the first state of the drilling apparatus 1, the operating element 50 is in a standby state, which is characterized by the standby location BL of the operating element 50. The operating element 50 protrudes in sections from the apparatus frame 30 in and / or along the directions R2 and R3.

[0178] The location of the bearing unit 60 with the bearing housing 61 for the pivotable mounting of the operating element 50 is clearly visible. In the top view of the drilling apparatus 1, the bearing unit 60 and, in particular, the first pivot axis 60X (see also FIG. 2) are arranged within the apparatus frame 30, which already provides a protected arrangement of the bearing unit 60 in a respective direction R1, R2, R3, with associated protected bearing of the operating element 50.

[0179] FIG. 4 shows the drilling apparatus 1 from FIG. 2 in the second state in a top view. The operating element 50 is in the parking location PL, that is, it has been adjusted from the operating location BL to the parking location PL and is retained in this location by the retaining element 70.

[0180] In the top view of the drilling apparatus 1, the operating element 50 extends in the state of the parking location PL, that is in the parking state, from the first frame side profile 31SP essentially parallel to the frame element 31Q and / or to the frame element 33Q toward the second frame side profile 32SP and ends within the apparatus frame 30, in particular in and / or along the third direction R3. In other words, in the top view of the drilling apparatus 1, the operating element 50 is arranged in the state of the parking location PL in and / or along the third direction R3 within the apparatus frame 30 in order to keep the operating element 50 protected by the apparatus frame 30.

[0181] In and / or along the second direction R2, the operating element 50 is also arranged within the apparatus frame 30 in the state of the parking location PL in order to keep the operating element 50 protected by the apparatus frame 30.

[0182] The operating element 50 can therefore be kept protected in the event of an external stress acting on the drilling apparatus 1 and in particular on the apparatus frame 30, thereby preventing damage to the operating element 50, for example. By the adjustable arrangement of the operating element 50 from the operating state and thus from the operating location BL into the parking state and thus into the parking location PL, an improved transport process of the drilling apparatus 1 can furthermore be ensured, for example.

[0183] In other words, the operating element 50 of the drilling apparatus 1 according to the present invention is characterized by an extended pivot angle range in order to be able to pivot the operating element 50 into a transport position. The operating element 50 can, for example, be pivotably mounted on the apparatus frame 30 in a pivot angle range of at least 70°. Alternatively, other pivot angle ranges are also conceivable. The apparatus frame 30 can form a stop for the operating element 50, which limits the pivot angle range of the operating element 50. In particular, the operating element 50 can be mounted and formed on the drilling apparatus 1 in such a way that the operating element 50 does not protrude above and / or out of the apparatus frame 30 in the transport position, for example.

[0184] In the view in the first direction R1, that is, in the top view of the work apparatus 1, that is, the drilling apparatus 1, the handle 81 forms a minimum distance D12 in the second direction R2 to a definable and / or idealized boundary line GL1, which serves to define a maximum dimension of the apparatus frame 30 in the second direction R2.

[0185] Corresponding to the handle 81, the handle 82 forms, in the second direction R2, a minimum distance D22 to a definable and / or idealized boundary line GL2, which serves to define a maximum dimension of the apparatus frame 30 in the second direction R2.

[0186] FIG. 5 shows the drilling apparatus 1 from FIG. 2 in the second state in a side view, that is, in a view in and / or along the second direction R2.

[0187] The arrangement of the bearing unit 60 of the operating element 50 within the apparatus frame 30 and the alignment of the first pivot axis 60X can be seen. In this view, the operating element 50 is arranged in the parking location PL within the apparatus frame 30 and is in turn kept protected by the apparatus frame 30.

[0188] In the view in the second direction R2, that is, in the side view of the work apparatus 1, that is, the drilling apparatus 1, the handle 81 and the handle 82 each form, in the first direction R1, a minimum distance to a definable and / or idealized boundary line GL3, which serves to define a maximum dimension of the apparatus frame 30 in the first direction R1, of which the minimum distance D21 of the handle 82 is visible and marked in FIG. 5.

[0189] The minimum distance D12 and / or D22 (see FIGS. 3 and 4) is each greater than the minimum distance D21. Alternatively, the opposite can also be the case, whereby the minimum distance D21 is greater than the minimum distance D12 and / or D22.

[0190] FIG. 6 shows an enlarged section of the work apparatus 1, that is, the drilling apparatus 1, from FIG. 2.

[0191] The fastening of the connecting element 120 to the longitudinal member 32L is realized by means of the mounting portion 120M of the connecting element 120 and by means of the front segment 32LS of the longitudinal member 32, wherein the formation of a screw connection is furthermore employed.

[0192] The fastening of the cross member 31Q via the front segment 31QS to the mounting section 120A of the connecting element 120 is also clearly visible, whereby a screw connection is also formed.

[0193] The mounting section 120M and the receiving section 120A are formed and / or arranged offset relative to each other in the three directions R1, R2, and R3, whereby the cross member 31Q and / or the handle 81 can be arranged in the defined, in particular offset, location.

[0194] The functional structure 125 for absorbing, distributing, and / or transmitting a stress energy when subjected to an external stress comprises several deformation zones in the form of chambers, which are arranged adjacent to each other and / or in a row. The chambers are connected to each other via respective wall sections of the connecting element 120.

[0195] The connecting element 120 is characterized above all by a relatively compact design. The connecting element 120 is, in particular, manufactured integrally in one piece and / or without forming, in particular by at least one of the following processes: an injection process, a casting process, a sintering process, a 3D printing process, a shrinkage process, a curing process. The connecting element 120 can be manufactured in particular by an injection molding process. The same applies to the other connecting elements 110, 130, and 140 of the work apparatus 1 from FIG. 2.

[0196] FIG. 7 shows the first connecting part 111 of the connecting element 110 of the work apparatus 1 from FIG. 1.

[0197] The first connecting part 111 comprises a channel 116 for contacting a first outer side of the longitudinal member 31L and / or the transition segment 31Ü, that is, a respective outer surface. The channel 116 is formed at least in sections essentially complementary to the first outer side of the longitudinal member 31L and / or the transition segment 31Ü.

[0198] Five contact ribs 117 are arranged one behind the other within the channel 116. The respective contact front faces of the contact ribs 117 are formed essentially complementary to the first outer surface of the longitudinal member 31L and / or the transition segment 31U in order to contact the longitudinal member 31L and / or the transition segment 310 at defined points in an assembly state and thus to fasten the connecting element 110 to the longitudinal member 31L.

[0199] The receiving section 110A for fastening the front segment 31QS of the cross member 31Q is also clearly visible. The receiving section 110A is formed on the first connecting part 111 and comprises the retaining segments 113, 114. The retaining segments 113, 114 are formed shell-shaped. The retaining segments 113, 114 are arranged spaced apart from each other and / or opposite each other.

[0200] As can be seen from the illustration in FIG. 7, the connecting element 110 comprises the bearing unit 60 with the bearing housing 61. The bearing unit 60 is configured to movably support the operating element 50. In particular, the bearing unit 60 is configured to pivotably support the operating element 50 so that it can pivot about the pivot axis 60X between the standby state, that is, the standby location BL, and the parking state, that is, the parking location PL. The bearing housing 61 can be an integral, one-piece component of the connecting element 110, in particular of the first connecting part 111.

[0201] The connecting element 110 and, in this case, the first connecting part 111 is formed and / or configured to arrange the bearing unit 60 with each an offset in relation to the apparatus frame 30, in particular to the cross member 31Q (not shown in FIG. 7), in at least one direction R1, R2, R3, in particular within the inner area 301 of the apparatus frame 30 (see also FIG. 1).

[0202] At least one reinforcing element 118 can each be formed and arranged between the receiving section 110A and / or the first connecting part 111 and / or the bearing housing 61 in order to stiffen the connecting element 110, that is the first connecting part 111, in at least one direction R1, R2, R3. The reinforcing element 118 can, for example, be formed as a rib or as a lamella.

[0203] A switching unit 150 is arranged on the at least one connecting element 110, in particular on a side opposite the bearing unit 60. In other words, the connecting element 110 comprises a switching unit 150.

[0204] The switching unit 150 is formed in particular as an electromechanical switching unit 150. The switching unit 150 is coupled to the bearing unit 60 and configured to close or interrupt a circuit for activating the actuator unit 40 of the work apparatus 1 when the operating element 50 is operated in the standby state.

[0205] The operating element 50 can be configured in the standby state by operating the switching unit 150 to activate the drilling apparatus 1, in which the drilling apparatus 1 is in an operational state. In addition or alternatively, the operating element 50 can be configured in the parking state by operating the switching unit 150 to deactivate the drilling apparatus 1, in which the drilling apparatus 1 is in a transportable state.

[0206] FIG. 8 shows, for further illustration, an enlarged section of the work apparatus 1 from FIG. 1 in a perspective view, wherein the operating element 50 is shown decoupled from the bearing unit 60. In addition, a housing part of the bearing unit 60 is hidden for reasons of clarity.

[0207] The arrangement of the bearing unit 60 of the operating element 50, which is offset inwards toward the inner area 301 relative to the outer sides 30A1 and 30A3 by the connecting element 110, is clearly visible, whereby the bearing unit 60 can be kept protected by the apparatus frame 30.

[0208] Furthermore, the illustration in FIG. 8 shows the fastening of the operating element 50 to a rotary guide (rotary body) of the bearing unit 60 by means of screw connections, which are not marked in detail and / or are partially hidden for reasons of clarity.

[0209] FIG. 9 shows an enlarged section of the work apparatus 1 from FIG. 1 in a perspective view, whereby some elements of the bearing unit 60 are hidden and / or indicated by dashed lines.

[0210] As can be seen from the illustration in FIG. 9, an applying element 190 is arranged on the connecting element 110, or the connecting element 110 comprises an applying element 190. The applying element 190 is configured, in particular at least in the standby state, to apply a preload force to the operating element 50 in order to retain the operating element 50, in particular to retain it in the standby state. The preload force can be a defined compressive force.

[0211] In the present embodiment, the applying element 190 is formed as a spring element, in particular as a coil spring element. The applying element 190 is arranged or received within the bearing unit 60, that is within a housing part of the bearing housing 61, and is guided along the pivot axis 60X. For this purpose, the housing part of the bearing housing 61 extends along the pivot axis in the form of a hollow cylinder in order to receive the applying element 190 therein.

[0212] The applying element 190 can be supported on the bearing unit 60. Alternatively, the applying element 190 can be supported on a frame element / frame section / frame segment of the apparatus frame 30.

[0213] The switching unit 150 is connected to the bearing unit 60, in particular to the applying element 190 for applying the preload force to the operating element 50, in a force-decoupled manner. The switching unit 150 can be formed as a rotary cam switching unit for this purpose.

[0214] FIG. 10 shows a further enlarged section of the work apparatus 1 from FIG. 1 in a further perspective view, in particular essentially in the first direction R1 and thus in a perspective top view.

[0215] A housing part of the switching unit 150 in the form of a cover is hidden so that further elements of the switching unit 150 are visible, which, however, are not marked in detail.

[0216] FIG. 10 clearly shows, among other things, that the switching unit 150 is also arranged within the apparatus frame 30 and thus within the inner area 301 of the apparatus frame 30, particularly in a top view of the work apparatus 1.

[0217] The formation or configuration of the connecting element 110, which in particular comprises the switching unit 150 and / or the bearing unit 60, or on which in particular the switching unit 150 and / or the bearing unit 60 are arranged, can, for example, avoid the need for a further (separate) mounting part for supporting the switching unit 150 and / or the bearing unit 60, which also characterizes the work apparatus 1 of the present invention.

[0218] By the present invention, in particular a work apparatus 1 can be provided which is further improved with respect to functionality and design. Furthermore, in particular an improved protection of respective elements and / or units can be ensured.

[0219] The present invention is not limited to the embodiments described above. Rather, a variety of variants and modifications are possible which also make use of the inventive concept and therefore fall within the scope of protection. In particular, the present invention also claims protection for the subject matter and features of the dependent claims independently of the claims referred to.LIST OF REFERENCE SIGNS1 work apparatus, drilling apparatus
