Description

Technical Field

[0001] This invention relates to a handle device for detachably securing to a handheld tool, particularly a drilling machine or a turning machine, wherein the handle device has a clamping ring and a handle with a clamping receptacle for accommodating a fixed section of the handheld tool, particularly the machine neck, the handle extending from the clamping ring and configured for gripping and / or holding by an operator, wherein the clamping receptacle is adjustable between a clamping position for clamping the fixed section of the handheld tool and a detached position for releasing the fixed section of the handheld tool by means of a clamping maneuverable handle operated manually by the operator, wherein in the clamping position, the inner peripheral surface of the clamping receptacle abuts against the fixed section of the handheld tool in a clamping engagement manner, and in the detached position, the fixed section of the handheld tool can be inserted into the clamping receptacle along an insertion axis, and wherein the handle device has an axially shaped fitting body movably supported with respect to the clamping receptacle, the axially shaped fitting body having an axially shaped fitting profile for engaging with a mating axially shaped fitting profile of the fixed section of the handheld tool. Background Technology

[0002] Such a handle device is described, for example, in DE 38 29 801 A1. The handle device has a sleeve with a so-called stop protrusion as an axial form-fit profile, which engages in a groove at the spindle journal of a hand-held tool by adjusting the clamping receptacle to a clamping position. The clamping receptacle achieves a friction-fit, clamping retention of the handle device on the hand-held tool. The axial form-fit profile serves as a locking or fixing part for an additional axial form fit with respect to the insertion axis. For adjusting the handle device with respect to the hand-held tool (e.g., involving rotational position with respect to the insertion axis) and / or for disengaging the handle device, the clamping fit should be disengaged such that the clamping receptacle is adjusted to the disengaged position during the initial rotational operation phase of the handle. Furthermore, the axial form fit must also be eliminated by means of a subsequent rotational operation phase of the handle.

[0003] DE 10 2008 000 516 A1 and WO 2009 / 109247 A1 describe a handheld tool machine with a spring element that protrudes elastically into a clamping receptacle as an axially shaped fit.

[0004] Other handle devices are known from DE 10 2006 041 069 A1 or DE 10 2016 207 755 A1.

[0005] In known handle devices, operation is inconvenient. Summary of the Invention

[0006] Therefore, the objective of this invention is to provide an improved handle device.

[0007] To address the aforementioned task, the handle device of the type mentioned at the beginning is configured to have a shape-fitting handle separate from the clamping handle and manually operable by an operator independently of the clamping handle, for adjusting the axial shape-fitting body between an engaged position and a released position, in which the axial shape-fitting profile and the mating axial shape-fitting profile are engaged and the handle device is shape-fittedly locked to a fixed section of the handheld tool about the insertion axis, and in the released position, the axial shape-fitting profile and the mating axial shape-fitting profile are disengaged and the handheld tool and the retaining device can be displaced relative to each other about the insertion axis.

[0008] The basic idea here is that the clamping ring can be adjusted between a clamping position and a disengaged position by means of a clamping operating handle, and the axial shape-fitting profile can be operated independently of or separately from the clamping operating handle or the clamping ring by means of a shape-fitting operating handle. That is, there are two operating handles that can be manually operated independently of or separately from each other.

[0009] The axial shape-fitting profile, independent of the clamping ring and / or clamping receptacle, can be movably supported and / or manipulated. The axial shape-fitting profile can be movably supported relative to the clamping receptacle.

[0010] The axial shape-fitting profile is preferably designed as a rib. The mating axial shape-fitting profile is designed as a groove, for example, especially as an annular groove.

[0011] A ramp or slope can be provided at the axial shape fit profile and / or the mating axial shape fit profile, which makes it easy for the axial shape fit profile and the mating axial shape fit profile to be brought into the engagement.

[0012] Advantageously, the axial form-fitting profile, when in the disengaged position of the clamping receiver and / or the disengaged position of the clamping ring, can be adjusted between an engaged position and a released position by means of a form-fitting operating handle. It is feasible that the clamping between the handle assembly and the handheld tool machine is disengageable; that is, the clamping ring can be adjusted to its disengaged position, while the axial form-fitting profile remains engaged with the mating axial form-fitting profile of the fixed section of the handheld tool machine.

[0013] Advantageously, the axial form-fitting profile secures the handle device in the engagement position with respect to the mating axis in an axially displaced and / or form-fitting manner at the fixed section, and / or is designed for such fixation. Thus, the lateral widths of the axial form-fitting profile and the mating axial form-fitting profile about the mating axis can be, for example, identical except for the movement clearance, which enables the axial form-fitting profile to be brought into engagement with each other. That is, when the axial form-fitting profile engages with the mating axial form-fitting profile, the handle device cannot be displaced along the mating axis about the fixed section.

[0014] Advantageously, the axial form-fit profile protrudes beyond the inner peripheral surface of the clamping receiver in the engaged position. This design of the axial form-fit profile is advantageous regardless of the clamping receiver's position. However, it is particularly advantageous that the axial form-fit profile protrudes beyond the inner peripheral surface of the clamping receiver in the engaged position when the clamping receiver is in its disengaged position. Thus, the clamping receiver can be disengaged, for example, without the axial form-fit being eliminated. Therefore, even if the clamping is disengaged, the axial form-fit between the handle device and the handheld tool machine can be maintained.

[0015] Advantageously, the axial shape-fitting profile protrudes further into the inner peripheral surface of the clamping receptacle in the engaged position than in the released position.

[0016] It can be configured such that the axial shape-fitting profile, in the release position, does not protrude before and / or aligns with and / or retracts after the inner peripheral surface of the clamping receiver. All the previously mentioned design schemes can be implemented, for example, by making the adjustment path of the axial shape-fitting profile correspondingly wide between the engagement and disengagement positions. Thus, multiple disengagement positions can be provided, for example. For instance, it is feasible that, although the axial shape-fitting profile still protrudes before the inner peripheral surface of the clamping receiver in the disengagement position, it is no longer engaged with the mating axial shape-fitting profile. Through the corresponding adjustment path of the axial shape-fitting profile, it can be further adjusted away from the inner peripheral surface of the clamping receiver, thereby aligning the axial shape-fitting profile with or adjusting it back to its position.

[0017] Advantageously, the axial shape-fitting profile protrudes radially inward in the engagement position before the annular or circular interlocking cross section of the clamping receptacle and adjusts back to or aligns with the interlocking cross section in the release position, thereby providing or releasing the annular interlocking cross section for insertion into the fixed section of the handheld tool machine in the release position of the axial shape-fitting profile.

[0018] The clamping and receiving part has, for example, a columnar shape.

[0019] In this regard, it should be mentioned that the insertion cross-section of the clamping receptacle is preferably annular and / or has a diameter of exactly or approximately 43 mm. Thus, the handle device is compatible with multiple handheld tool machines whose fixed sections have clamping portions whose outer peripheries are approximately annular and / or have a diameter of approximately 43 mm. Even if the handheld tool machine does not have a matching mating axial shape-fit profile, the axial shape-fit profile of the handle device does not cause interference when it occupies or is adjusted to the release position.

[0020] Preferably, the clamping ring as a whole and / or in the region of the clamping receptacle is non-conductive or electrically insulating. Advantageously, at least the clamping receptacle is electrically insulating or non-conductive. For example, the clamping receptacle or clamping ring as a whole is made of plastic material, especially non-conductive plastic material. However, a metal clamping ring is also feasible, directly providing the clamping receptacle. For electrical insulation, the metal clamping ring can be equipped with an electrically insulating coating in the region of the clamping receptacle.

[0021] The axial shape-fitting body is preferably a body separate from the clamping ring. The axial shape-fitting body is preferably a body separate from the clamping ring. The axial shape-fitting body is preferably not a one-piece assembly with the clamping ring.

[0022] Preferably, the axial shape fit is adjustable independently of the clamping handle between the engaged and released positions and / or is not kinematically coupled to the clamping handle and / or is not in actuated engagement.

[0023] Preferably, the axial form-fitting body can only be manipulated between an engaged position and a released position by a form-fitting operating handle, particularly from the engaged position to the released position and / or from the released position to the engaged position.

[0024] Advantageously, the axial shape-fitting body cannot be operated by a clamping handle. Thus, for example, the clamping handle can be adjusted to a clamping position corresponding to the clamping receptacle and / or to a disengaged position corresponding to the clamping receptacle, without adjusting the axial shape-fitting body between the engaged and released positions.

[0025] Advantageously, when the clamping receiving part is in the clamping position, the axial shape-fitting body can be adjusted between the engaged position and the released position. Thus, even when the clamping ring clamps the fixed section of the handheld tool machine, the axial shape-fitting body can be adjusted to the released position.

[0026] It is understood that multiple axial shape-fitting profiles can be provided, that is, at least two axial shape-fitting profiles can be provided. The axial shape-fitting profiles can be located at the same axial shape-fitting body. However, it is also feasible to provide multiple axial shape-fitting bodies.

[0027] To manipulate at least one axial form-fitting body, a unique form-fitting operating handle can be provided. This handle is connected to one or more axial form-fitting bodies, for example, via a transmission mechanism, drive assembly, or the like. However, it is also possible to provide multiple form-fitting operating handles for one or more axial form-fitting bodies. Thus, the operator can simultaneously manipulate the same or multiple axial form-fitting bodies, for example, by operating different form-fitting operating handles, such as two different handles.

[0028] Advantageously, the axial form-fitting body and the form-fitting operating handle are fixedly connected to each other or are one piece. Alternatively, a drive mechanism and / or transmission mechanism or the like may be arranged between at least one form-fitting operating handle and at least one axial form-fitting body. The drive mechanism may be, for example, a transmission mechanism. The drive mechanism may also include a Freigang between the axial form-fitting body and the form-fitting operating handle.

[0029] While it is feasible for the axial shape-fitting body to be manually manipulated from the engaged position to the released position and vice versa, it is preferable that the axial shape-fitting body is loaded into the engaged position by a spring assembly. Thus, the operator overcomes the force of the spring assembly to manipulate the axial shape-fitting body in the direction toward the release position, while the spring assembly acts in the opposite direction (i.e., into the engaged position). For example, the axial shape-fitting body is designed as a locking unit that is loaded in the direction toward the engaged position.

[0030] The spring assembly includes, for example, a helical spring and / or a metal spring. Preferably, the spring assembly is passed through or penetrated by a clamping anchor for adjusting the clamping ring between a disengaged position and a clamped position.

[0031] Advantageously, the spring assembly includes at least one spring that is separate from the axially shaped fitting.

[0032] The spring assembly is preferably not formed by an elastic hinge portion of the axial shape-fitting body and / or not by a spring separate from the axial shape-fitting body. That is to say, the axial shape-fitting body itself does not have elastic properties, for example, in a way that allows it to be elastically hinged to other bodies, such as clamping rings.

[0033] However, it is clearly feasible for the spring assembly to be formed or include a spring-elastic hinge portion, for example, an axially shaped fit at the base of the clamping ring.

[0034] Preferably, the axially shaped fitting is supported relative to the clamping ring in a linearly displaceable manner along the adjustment axis. A spring or spring assembly acts on the axially shaped fitting, particularly along the direction of the adjustment axis. It is feasible that the axially shaped fitting is supported relative to the clamping ring only in a linearly displaceable manner along one or more adjustment axes. Furthermore, it is feasible that the axially shaped fitting is not allowed to twist or oscillate relative to the clamping ring. Advantageously, the axially shaped fitting is supported only linearly with respect to the clamping ring, but not oscillatingly.

[0035] However, alternatively, it is also feasible to support the axially shaped fitment in a swinging motion between the engagement and release positions, or in a displaceable swinging motion, or along a curved track. For example, the axially shaped fitment can be supported between the release and engagement positions by means of a swinging support member, or by means of a slider guide along a curved track and / or in a displaceable swinging motion. The swinging support member can, for example, have an axial unit connected to the axially shaped fitment, which is swingably supported at the support receiving portion about a swinging axis.

[0036] Preferably, a guide mechanism or linear support is provided to provide a displaceable support for the axially oriented form-fitting body. Preferably, a guide mechanism is provided and / or arranged at the handle and / or clamping ring for linearly guiding the axially oriented form-fitting body along the adjustment axis. For example, the guide surface of the guide mechanism can be arranged not only at the clamping ring but also at the handle, particularly at the support of the handle, where the axially oriented form-fitting body is linearly supported about the adjustment axis.

[0037] Preferably, the axis is adjusted to be tangential to or radially tangential to the inner peripheral surface of the clamping and receiving portion.

[0038] Advantageously, the axial shape-fitting profile has a bevel or wedge for abutting and / or wedging against the mating axial shape-fitting profile, for example, its bottom. The bottom is, for example, the bottom of a groove in the mating axial shape-fitting profile designed as a slot. Particularly advantageously, the axial shape-fitting body is designed as a wedge or has a wedge shape, designed and / or configured to wed against the mating axial shape-fitting profile of a handheld tool machine. Preferably, the bevel or wedge is slightly inclined about the adjustment axis. For example, the bevel or wedge has a slope of less than 30°, especially less than 25°, preferably even less than 20° or less than 15°. That is, the bevel or wedge and the adjustment axis are angled relative to each other at this angle. In this regard, it should be mentioned that the bevel or wedge can also have an arcuate shape or arcuate sections. Therefore, the bevel or wedge does not necessarily have to be a flat or planar surface.

[0039] The adjusting force, acting along the adjusting axis, is amplified by the slope of the wedge or ramp, and the axial shape-fitting body acts on the mating axial shape-fitting profile by means of this clamping force. The spring force of the spring assembly, for example, acting on the axial shape-fitting body, generates a clamping force on the mating axial shape-fitting profile, for example, to its bottom. This clamping force is amplified, in particular, several times, by the small angle between the ramp or wedge on one side and the adjusting axis on the other, as mentioned earlier. That is, the tangential force introduced by the axial shape-fitting body is arguably enhanced.

[0040] A preferred design is that the handle has a longitudinal central axis, and the adjustment axis is parallel to or coaxial with the longitudinal central axis.

[0041] Advantageous measures are provided such that the axial shape-fitting profile is supported in a way that allows for displacement with respect to the inner peripheral surface of the clamping receiver and / or tangentially with respect to the center of the clamping receiver.

[0042] Preferably, the clamping handle and the form-fit handle are supported with respect to the clamping ring in different degrees of freedom of movement; that is, for example, the clamping handle can rotate with respect to the clamping ring, and the form-fit handle can displace with respect to the clamping ring. Thus, an embodiment is provided in which the clamping handle is rotatably supported with respect to the clamping ring to adjust the clamping receiving portion between a clamping position and a disengaged position, and the form-fit handle is displaced with respect to the clamping ring to adjust the axial form-fit body between an engaged position and a released position. However, it is also generally conceivable that the form-fit handle is also rotatably supported with respect to the clamping ring to adjust the axial form-fit profile between the engaged position and the released position. Here, it is feasible to convert the rotational movement of the form-fit handle into linear movement of the form-fit profile by means of a transmission mechanism.

[0043] The axial form-fitting body and the clamping actuation mechanism are advantageously arranged coaxially, especially with respect to the clamping axis, which will be explained later, and / or the longitudinal axis of the clamping anchor, which will also be explained later.

[0044] Advantageously, the clamping and operating handle is formed by or has a lever-shaped handle body that can be gripped by the operator with the inside of their hand. That is, the handle body forms part of the handle, particularly important part or main part, which extends from the clamping ring and is for holding and guiding the handheld tool machine so that the operator can grip and / or hold it.

[0045] By changing, for example, the handle body or using different handle bodies, the handle can be designed with different geometries, such as different diameters and / or different lengths. This allows for seamless ergonomic matching.

[0046] Advantageously, the form-fitting control handle is positioned between the clamping control handle and the clamping ring. This means that the operator can manipulate the form-fitting control handle, for example, by gripping the clamping control handle or the handle body with their thumb and / or forefinger.

[0047] An advantageous design provides a gap between the gripping section of the clamping handle (e.g., the previously mentioned handle body) for gripping the clamping handle and the gripping surface of the form-fitting handle for manual operation, approximately corresponding to the distance between the thumb joint and the index finger of an adult operator's hand when the thumb is extended. This allows the operator to grip the gripping section of the clamping handle while simultaneously manipulating the form-fitting handle with the thumb joint. The operator can, for example, axially move the form-fitting handle toward the gripping section of the clamping handle, particularly for manipulating the axial form-fitting body in the direction toward the release position.

[0048] On the side facing the form-fitting control handle, the handle body that holds the control handle preferably has a support protrusion, especially a flange protrusion, at which the operator's hand can be supported, especially for operating the form-fitting control handle.

[0049] Advantageously, the shape of the operating handle is designed as a ring or a sleeve. Such a sleeve particularly has a gripping surface configured for operation by the operator, the gripping surface being oriented upward toward its side away from the clamping ring and / or having a gripping notch.

[0050] The clamping handle is preferably supported at the clamping ring independently of the shape-fitting handle.

[0051] For manipulating the clamping ring, a clamping anchor is advantageous. For example, the clamping ring can be adjusted between a clamping position and a disengaged position via the clamping anchor. The clamping anchor can be manipulated linearly along the clamping axis by clamping the handle body of the operating handle, for example, via the aforementioned handle body. Preferably, the handle body is rotatably supported at the base of the handle about the clamping axis and forms a clamping operating body. A threaded section is provided at the clamping anchor, for example, which is screwed into a screw-in receiving portion that is anti-rotatably connected to the handle body. By rotating the operating handle body, the clamping anchor can be linearly adjusted relative to the screw-in receiving portion to adjust the clamping ring between the clamping position and the disengaged position.

[0052] The clamping anchor, like the handle body already mentioned, is preferably replaceable.

[0053] It is feasible to achieve larger or smaller gaps by using clamping anchors of different lengths, for example, by designing the handle length differently and / or between the clamping ring and the clamping operating handle, especially the handle body. For example, distance elements of different lengths, especially the supports mentioned in the detailed description, can be arranged between the clamping operating handle and the form-fit operating handle, especially such distance elements penetrated by clamping anchors.

[0054] The clamping anchor is, for example, a rod-shaped or pin-shaped structural component. The clamping anchor can, for example, tension the opposing ring ends of the clamping rings toward each other in order to adjust them in the direction toward the clamping position, and release them to move away from each other in order to disengage (that is, in the direction toward the disengagement position) or actively adjust the ring ends away from each other in the direction toward the disengagement position.

[0055] In other words, the clamping anchor extends, for example, between the clamping ring and the clamping operating handle, especially its handle body.

[0056] Advantageously, the axially shaped fit is guided by a clamping anchor through which and / or at the clamping anchor. That is, the clamping anchor can simultaneously form a guiding element for the axially shaped fit or the already mentioned guiding mechanism.

[0057] In a preferred embodiment, the handle assembly is configured such that it has at least one rotational shape-fitting profile for engagement with a mating rotational shape-fitting profile at a fixed section of the handheld tool machine, wherein the mating rotational shape-fitting profile and the rotational shape-fitting profile, when engaged with each other, fix the handle assembly relative to the fixed section of the handheld tool machine about a mating axis without rotation. The rotational shape-fitting profile and the mating rotational shape-fitting profile can be brought into engagement and disengaged, for example, by relative movement of the fixed section and the handle assembly along the mating axis. The rotational shape-fitting profile and the mating rotational shape-fitting profile are designed, for example, as ribs, teeth, or the like, or have such a structure. For example, annular teeth can be used as the rotational shape-fitting profile and the mating rotational shape-fitting profile. The rotational shape-fitting profile is designed in particular such that the handle assembly can be fixed relative to the fixed section without torsion about the mating axis in at least two, preferably multiple, angular positions.

[0058] For example, a rotating shape-fitting profile is arranged on the end side of the clamping ring through which the insertion axis passes. It is particularly advantageous that rotating shape-fitting profiles are correspondingly provided on opposite end sides of the clamping ring. Thus, the handle assembly can be fixed in the fixed section in opposite assembly positions, wherein the rotating shape-fitting profiles engage with each other. In both assembly positions, the handle extends from the fixed section of the handheld tool machine on the corresponding other opposite side.

[0059] Advantageously, the axial form-fitting profile secures the handle assembly in the engagement position in a fixed section with resistance to axial displacement about the insertion axis and / or with proper form fit, such that the rotary form-fitting profile remains engaged with the mating rotary form-fitting profile, and / or is designed for this securing. For example, the spacing between the axial form-fitting profile and the rotary form-fitting profile, or the spacing to the opposing ends of the clamping ring, is designed to secure the handle assembly in the engagement position in a fixed section with resistance to axial displacement about the insertion axis and / or with proper form fit, such that when the handle assembly is mounted in the fixed section, the rotary form-fitting profile is held engaged with the mating rotary form-fitting profile.

[0060] An advantageous design allows the handle device to be axially displaced, yet prevented from loss, in a fixed section relative to the mating axis in either the engaged position or an intermediate position between the engaged and disengaged positions of the axially fitted profile and the mating axially fitted profile. For example, it is feasible for the axially fitted profile to retain the handle device in a fixed section with resistance to displacement in the engaged position and to remove the handle device from the fixed section in the disengaged position, while in the intermediate position, a portion or a section of the axially fitted profile engages with the mating axially fitted profile, yet allowing axial clearance of the handle device relative to the fixed section of the handheld tool machine with respect to the mating axis.

[0061] For example, the lateral width of the mating axial shape-fitting profile with respect to the interlocking axis can be designed to be sized and / or provide an adjustment path such that, while the axial shape-fitting profile engages with the mating axial shape-fitting profile, it can be movably accommodated therein in the engagement position or the aforementioned intermediate position along the interlocking axis. It is also possible that this axial mobility or adjustment path is achieved, for example, by an inclined profile of the axial shape-fitting profile and / or by a retaining protrusion of the axial shape-fitting profile, the inclined profile extending obliquely relative to the free end region or front region of the axial shape-fitting profile, the retaining protrusion protruding before the base of the axial shape-fitting profile, or the like.

[0062] Preferably, the axial adjustment path in the engaged position, or especially in the aforementioned intermediate position, is designed with dimensions such that the rotating shape-fitting profile of the handle device and the mating rotating shape-fitting profile of the fixed section can be brought into disengagement from each other and into engagement with each other. That is to say, while the axial shape-fitting profile engages with the mating axial shape-fitting profile, thus holding the handle device securely in the fixed section without loss, the handle device can move away from the mating rotating shape-fitting profile along the insertion axis, thereby enabling it to rotate about the insertion axis.

[0063] Preferably, the handheld tool is a drilling machine or a turning machine. The handheld tool advantageously forms part of a system comprising the handheld tool and a handle device. Preferably, the working tool that can be mounted on the handheld tool is a drilling tool or a turning tool. Attached Figure Description

[0074] System 5 includes a handheld tool machine 10, such as a screwdriver, and a handle device 30.

[0075] The housing 11 of the handheld tool machine 10 has a drive section 12 from which a handle section 13 protrudes. An energy storage device 14A, such as a battery pack, can be detachably arranged at a free foot section 14 of the handle section 13, away from the drive section 12, for supplying power to the handheld tool machine 10. Alternatively to or supplementing the removable energy storage device 14A, the handheld tool machine 10 also has a network connection, particularly a network cable, for connecting to a power supply network.

[0076] A drive motor 15, such as an electric or pneumatic drive motor, is arranged in the drive section 12. It has a tool receiving portion 17 for accommodating working tools 19, such as turning tools or drilling tools, directly or via a transmission mechanism 16. The drive motor 12 drives the tool receiving portion 17, for example, about a rotation axis DA.

[0077] The drive motor 15 can be turned on and off by means of the switching element 18, and its speed can be changed.

[0078] The tool receiving section 17 is provided in the fixed section 20 of the handheld tool machine 10, such as the so-called machine neck.

[0079] Objects, such as drill presses and, in particular, the handle device 40 explained later, can be inserted into the fixed section 20 along the insertion axis S.

[0080] The fixed section 20 has a receiving section 21 extending from its free end 22 to the end 23 of the machine housing 11 (particularly the drive section 12), where a tool receiving portion 17 is arranged. The receiving section 21 has a cylindrical shape about the insertion axis S. The receiving section 21 has a retaining surface 24, which is designed as a cylindrical circumference or a cylindrical circumference extending about the insertion axis S. The retaining surface 24 is suitable for use as a clamping surface. The end 23 is at an angle, for example, a right angle, relative to the retaining surface 24.

[0081] To secure the object in a shape-fitting manner at the fixing section 21 parallel to the insertion axis S, a mating axial shape-fitting profile 22 is provided at the retaining surface 24. A mating axial shape-fitting profile 25 is provided at the receiving section 21 between end sides 22 and 23. The mating axial shape-fitting profile 25 is designed, for example, as a groove 26, having a bottom 27, with sidewalls or support surfaces 28 extending away from the bottom to the retaining surface 24, for example, extending at right angles.

[0082] Preferably, the mating axial shape-fitting profile 25 extends around the entire outer periphery of the receiving section 21 about the insertion axis S. However, it is also possible for the mating axial shape-fitting profile to extend only on a portion of the periphery of the receiving section 21. Advantageously, multiple mating axial shape-fitting profiles can also be provided, for example, arranged adjacent to each other about the insertion axis S and / or adjacent to each other about the insertion axis S in the peripheral direction at the receiving section 21. The mating axial shape-fitting profiles arranged adjacent to each other about the insertion axis S can be designed, for example, in the form of a rib structure comprising two or more receiving slots. The mating axial shape-fitting profiles arranged adjacent to each other about the insertion axis S in the peripheral direction at the receiving section 21 can extend, for example, correspondingly in angular segments around the insertion axis S, for example, designed as partially annular receiving slots.

[0083] A rotating shape-fitting profile 30 is used to hold an object in a fixed section 20 in a circumferential or rotational direction about the insertion axis S. The rotating shape-fitting profile 30 protrudes, for example, before the end side 23 up to the retaining surface 24 and / or radially outwards before the retaining surface 24. The rotating shape-fitting profile 30 has, for example, a plurality of shape-fitting protrusions 31 protruding parallel to the insertion axis S before the end side 23. The rotating shape-fitting profiles 30 have the same radial spacing 32 about the insertion axis S, so that the object to be fixed in the fixed section 20 can be fixed in multiple angular positions, the angular spacing of which corresponds to the spacing 32.

[0084] The fixed section 20 is disposed at the fixed body 35 of the handheld tool machine 10, forming part of or being connected to the machine housing 11. The fixed body 35 includes a peripheral wall 36 (whose radial outer periphery provides a retaining surface 24) and an end wall 37 that protrudes in a flange-like manner before the peripheral wall 36, where an end side 23 is disposed.

[0085] An accessory 17A, such as a drill chuck, an angle attachment (Winkelvorsatz), or the like, can also be arranged at the tool housing 17. The working tool 19A (e.g., a drill) can be detachably fixed to the accessory 17A (according to...). Figure 2 (Example: drill chuck). It is crucial for drilling operations that the operator can securely grip the handheld tool to maintain control over the forces generated during drilling. For this purpose, the handheld tool can be gripped not only at its housing 11, for example at the handle section 13 and, if necessary, at the drive section 12, but also via a handle device 40 that is detachably connected to the handheld tool 10.

[0086] The handle assembly 40 has a clamping ring 41 for securing to the handheld tool machine 10. The clamping ring 41 includes a clamping receiving portion 42 into which the fixing section 20 of the handheld tool machine 10 can be inserted along the insertion axis S. The clamping receiving portion 42 has a columnar inner peripheral surface 43, particularly a clamping surface, which is provided and designed to clamp against the retaining surface 24 of the handheld tool machine 10. When the clamping receiving portion 42 is in a clamping engagement with the retaining surface 24, the handle assembly 40 is frictionally held at the handheld tool machine 10.

[0087] The clamping ring 41 has an annular body 44 that restricts the clamping receiving portion 42. The annular body 44 has a slit 45A on its peripheral side, by means of which the insertion cross-section of the clamping receiving portion 42 can be adjusted about the insertion axis S. The slit 45A is radially oriented about the insertion axis S. The annular ends 45 and 46 of the annular body 44 are opposite each other in the region of the slit 45A. The insertion cross-section of the clamping receiving portion 42 can be reduced about the insertion axis S by manipulating the annular ends 45 and 46 of the clamping ring 41 toward each other along the clamping axis SP, so as to clamp the fixed section 20 of the handheld tool machine in the clamping position K thus formed. The clamping position K is in Figure 7 The image is shown in dashed lines. As the ring ends 45 and 46 move away from each other, the insertion cross-section of the clamping receiving portion 42 increases and is adjusted to the disengagement position L, which is... Figure 7 As shown in solid lines, in the disengaged position, the fixed section 20 is able to shift within the clamping receiving portion 42 about the insertion axis S.

[0088] Rotational shape-fitting profiles 50, located at opposite ends 47 and 48 of the clamping ring 41 and for engaging the rotational shape-fitting profile 30 of the handheld tool machine 10, are responsible for preventing the clamping ring 41 from twisting about the insertion axis S at the fixed section 20. By providing rotational shape-fitting profiles 50 at each end 47 and 48 of the clamping ring 41, the rotational shape-fitting profile 30 of the fixed section 20 can be correspondingly brought into engagement with the rotational shape-fitting profile 50 of the handle device 40 along each insertion direction about the insertion axis S.

[0089] The rotating shape-fitting profile 50 includes a shape-fitting receiving portion 51 for engaging the shape-fitting protrusion 31, which has an angular spacing 52 about the insertion axis S, the angular spacing corresponding to the spacing 32. Advantageously, the shape-fitting receiving portion 51 has an angular width about the insertion axis S in the regions of the ring ends 45 and 46 of the clamping ring 41, so as to achieve a movement clearance of the clamping ring 41 about the rotating shape-fitting profile 30 in the regions of the ring ends 45 and 46 when adjusted from the disengaged position L to the clamping position K.

[0090] A handle 60 extends from a clamping ring 41. The handle 60 has a support body 61 supported at the clamping ring 41. The support body 61 includes a sleeve body 62, with a support protrusion 63 protruding before the sleeve body. The support protrusion 63 protrudes to a receiving portion 53 at the annular end 46 of the annular body 44. A support profile 64 of the support body 61 is supported about the clamping axis SP at a support profile 54 of the clamping ring 41. The support profile 54 is constructed, for example, at the end side of the peripheral wall 55 of the receiving portion 53, but can also be included, without problem, as a stepped portion inside the receiving portion 53.

[0091] A clamping anchor 66 is used to adjust the clamping ring 41 between a clamping position K and a disengaged position L. The clamping anchor passes through the clamping ring 41 in the regions of the ring ends 45 and 46, so as to allow or induce movement of the ring ends 45 and 46 toward each other in order to adjust the clamping receptacle into the clamping position K, or to allow or induce movement of the ring ends 45 and 46 away from each other in order to adjust in the direction toward the disengaged position L. The clamping anchor 66 has a head 67 anti-torsionally received in a receptacle 49 at the ring end 45, which is arranged at the pin section 68. The head 67 and the receptacle 49 have, for example, complementary, particularly polygonal, anti-torsional profiles.

[0092] The pin section 68 passes through the through openings 56 and 57 at the ring ends 45 and 46 and the support 61, and engages with the free ring end into the insertion opening 77 of the handle body 70 of the handle 60. A thread is provided at the free end of the pin section 68, which screws into a nut 69, which is torsionally accommodated in the handle body 70.

[0093] Furthermore, it is advantageous to provide a stop 69A, such as a torsionally secured nut, flange protrusion, or the like, at the free end of the pin section 68, which restricts the nut 69 along the adjustment path of the pin section 68, thereby preventing the nut 69 from being lost and / or the pin section 68 from being completely unscrewed from the nut 69. Thus, the stop 69A forms an anti-loss feature for the nut 69.

[0094] The handle 60 and, in particular, the handle body 70, have a longitudinal profile and extend along the longitudinal central axis LM of the handle 60.

[0095] The handle body 70 is torsionally oriented about a rotation axis D relative to the support body 61 and relative to the annular body, the rotation axis preferably being coaxial with the clamping axis SP and / or coaxial with the longitudinal central axis LM. This allows the nut 69 to be tightened along the pin section 68, thereby moving the head 67 of the clamping anchor 66, which forms the support body, toward or away from the handle body 70. Consequently, the ring end 45 is manipulated toward the ring end 46 into the clamping position K, or manipulated or released in the direction toward the disengaged position for movement away from the ring end 46. The operator BE's hand H can, for example, grasp the gripping section 71 with multiple fingers F and rotate the handle body 70 about the rotation axis D, thereby rotating the operating nut 69. The handle body 70 forms a clamping operating handle 78 for adjusting the clamping receiving portion 42 between the disengaged position L and the clamping position K.

[0096] Obviously, instead of nut 69, threads can also be provided directly or integratedly on handle body 70 for screwing into pin section 68. In addition, handle body 70 can also have a screwing protrusion that screws into a screwing receiving portion at the ring end 45 of annular body 44 to facilitate clamping operation with respect to clamping axis SP.

[0097] The handle body 70 has a gripping section 71 for the operator to grip. The gripping section 71 extends between support protrusions 72 and 73, which are located at the free end region of the handle 60 or facing the support body 61. The support protrusions 72 and 73 are designed as flange protrusions. The handle body 70 also has a retaining and receiving portion 74 for the nut 69.

[0098] An elastic layer 75 is preferably provided in the area of ​​the gripping section 71 and / or the support protrusion 72.

[0099] A reinforcement 76 is advantageously provided at the support protrusion 73, by means of which the handle body 70 is supported at the support body 61.

[0100] An axially shaped fitting 80 is used to axially and shaped-fit lock or secure the handle assembly 40 about the insertion axis S to a fixed section 20 of the handheld tool machine 10. The axially shaped fitting has an axially shaped fitting profile 81 for engagement with a mating axially shaped fitting profile 25 in the fixed section 20. The axially shaped fitting profile 81 has a front face 82 that, when engaged with the mating axially shaped fitting profile 25, opposes or supports the bottom 27 of the groove 26. A support surface 83, such as a side or sidewall, extends angularly away from the front face 82 (e.g., at a right angle), configured for shaped-fit support at the support surface 28 of the groove 26.

[0101] The axial shape-fitting body 80 is supported by a guide mechanism 87 along the adjustment axis SA between the engagement position E and the disengagement position L. In the engagement position, the axial shape-fitting profile 81 is engaged with the mating axial shape-fitting profile 25 or the groove 26. In the disengagement position, the axial shape-fitting body 80 or the axial shape-fitting profile 81 is disengaged from the mating axial shape-fitting profile 25.

[0102] The front face 82 is inclined about the adjustment axis SA and forms a ramp 82B or has a ramp as an introduction ramp 82B. The introduction ramp 82B makes it easy to bring the axial shape mating profile 81 and the mating axial shape mating profile 25 into engagement.

[0103] The clamping anchor 87 can be used, for example, as part of the guide mechanism 87, and the clamping anchor penetrates the through opening 86 of the axial shape-fitting body 80. The axial shape-fitting body 80 is supported about the adjustment axis SA with displacement along the clamping anchor 87.

[0104] Furthermore, the receiving portion 53 at the clamping ring 41 is designed to receive and / or guide the axial shape-fitting body 80. The axial shape-fitting body 80 is received in the receiving portion 53 and / or guided along the adjustment axis SA.

[0105] A generally cylindrical segment 88 of the axially shaped fitting 80 is, for example, accommodated in a generally cylindrical guide receiving portion 58 at the ring end 46.

[0106] In the release position F, the axial shape-fitting body 80 is only in and / or retracted into the guide receiving portion 58. In the engagement position E, the axial shape-fitting body 80 protrudes beyond the guide receiving portion 58 and is recessed into the support receiving portion 59 at the ring end 47, which is opposite to and aligned with the guide receiving portion 58. However, it is also generally feasible for the axial shape-fitting body 80, for the corresponding length, to also at least partially engage in the support receiving portion 59 in the release position F. Preferably, the support receiving portion 59 and the guide receiving portion 58 have the same cross-section transverse to the adjustment axis SA. Thus, the axial shape-fitting body 80 is supported transversely to the insertion axis S in the engagement position E at the two ring ends 46 and 47, and thereby the handle device 40 is optimally supported at the fixed section 20 of the handheld tool machine 10 with respect to the force acting axially along the insertion axis S.

[0107] Furthermore, the axial shape-fitting body 80 is preferably guided in an anti-torsional manner with respect to the adjustment axis SA at the handle device 40, for example, with respect to the clamping ring 41. For this purpose, the axial shape-fitting body 80 has, for example, an anti-torsional profile 89, particularly a guide protrusion that projects radially outward with respect to the insertion axis S, which engages with a mating anti-torsional profile 59A, such as a groove, slot, or similar guide receiving portion. The anti-torsional profile 89 and the mating anti-torsional profile 59A extend parallel to the adjustment axis SA and preferably have a longitudinal profile with respect to the adjustment axis.

[0108] The form-fitting operating handle 90 is used to operate the axial form-fitting body 80. Although the form-fitting operating handle 90 can in principle be kinematically coupled to the axial form-fitting body 80, for example by coupling the drive contours that engage with each other, it is preferred to be a single piece with the axial form-fitting body 80.

[0109] The form-fitting operating handle 90 includes a gripping section 91 designed as a sleeve body 91A, located at the end region of section 88 of the axial form-fitting body 80 opposite to the axial form-fitting profile 81. The gripping section 91 has a gripping surface 92, which preferably has an inclined profile and / or a gripping notch. The gripping surface 92 rises from the clamping ring 41 in the direction toward the handle body 70. Thus, the gripping surface 92 can be easily grasped by the thumb DA of the operator BE, and when the operator BE grips the handle body 60 with his other fingers F, it can be operated along the adjustment axis SA in the direction toward the handle body 60.

[0110] On its side facing the clamping ring 41, the form-fitting operating handle 90 has a receiving portion 93 into which a peripheral wall 55 engages, the peripheral wall constraining the receiving portion 53 at the clamping ring 41. The components engaged with each other also form part of the guiding mechanism 87. In any case, the peripheral wall 55 engages with the receiving portion 93 of the gripping section 91 in the engaged position E. Advantageously, the peripheral wall 55 also engages at least partially with the receiving portion 93 in the released position F.

[0111] The axially shaped fitting 80 and its axially shaped profile 81 are spring-loaded into the engagement position E by a spring assembly 95. The spring assembly 95 includes a spring 96, such as a coil spring. The spring assembly 95 is supported on the axially shaped fitting 80 in a receiving portion 94, for example, at the longitudinal end region of section 88 facing the handle body 70; and on the support body 61, for example, at its support protrusion 63, particularly at the end side of the support protrusion 63. That is, the axially shaped fitting is actuated from the engagement position E to the release position F by the force of the spring assembly 85. The release position F is equipped with a stop 65 that fixes the position of the handle 60. The stop 65 is formed by or provided by, for example, the support profile 64 of the support body 61, and the stop 97 of the gripping section 91 stops at said support profile in the release position F.

[0112] In order to facilitate the engagement of the axial shape-fitting profile 81 with the groove 26, a slope 84 is provided on the front surface 82, which rises toward the free end 85 of the axial shape-fitting body 80, such that the free end 85 has a larger distance to the clamping and receiving portion 42 or the inner peripheral surface 43 compared to the region of the front surface 82 facing the axial shape-fitting body 80.

[0113] Advantageously, a rounded region 82A is provided on the front surface 82, the rounded portion of which approximately corresponds to the rounded portion of the inner peripheral surface 43, so that region 82A can fit in a form fit against the bottom 27 of the groove 26 in the engagement position E.

[0114] A slope or wedge surface 82B is further constructed at the front face 82, which can be brought into engagement with the mating axial shape-fitting profile 25 in a wedge-like manner. The wedge surface 82B is inclined at an angle α relative to the adjustment axis SP. The angle α is, for example, an acute angle of about 5° to 25°, and in the present case about 10° to 15°. Through the wedge surface 82B, the adjustment force Fs acting along the adjustment axis SP, for example generated by the spring assembly 95, is converted into a clamping force Fa, which acts on the bottom 27 of the mating axial shape-fitting profile 25. Therefore, the slight slope of the wedge surface 82B, that is, the small angle α, here results in an increased force, that is, the clamping force Fa is greater than the adjustment force Fs, especially several times greater.

[0115] Advantageously, the handle device 40 has a depth stop element 99 for setting the insertion depth of the working tool 19 or 19A into the workpiece. The depth stop element 99 is, for example, a rod, which is displaceably received in a receiving portion 98 of the handle device 40 parallel to the insertion axis S. The receiving portion 98 is provided at the clamping ring 41, particularly at the ring end 45.

[0116] When the handle assembly 40 should be removed from the handheld tool machine 10, it is configured such that the clamping receiving part 42 is first adjusted from the clamping position K to the disengaged position L. For this, it is sufficient to slightly twist the handle body 70 (that is, the clamping operating handle 78) about the rotation axis D. Then, the operator disengages the form-fit locking by adjusting the axial form-fit body 80 from the engaged position E to the released position F, i.e., by adjusting the form-fit operating handle 90 in the direction toward the handle body 70, for example, by shifting it using the thumb joint DAG at the front of the thumb DA. For this, a short adjustment path is sufficient. The operator can then, for example, completely remove the handle assembly 40 from the fixed section 20 of the handheld tool machine 10, that is, remove it along the insertion axis S.

[0117] Alternatively, the operator can adjust the handle device 40 only partially along the insertion axis S, thereby disengaging the rotating form-fitting profiles 30, 50 and allowing the handle device 40 to rotate about the insertion axis S relative to the handheld tool machine 10. If a suitable angular position of the handle device 40 relative to the machine housing 11 is set, then the handle device 40 is adjusted towards the machine housing 11 along the insertion axis S, wherein the rotating form-fitting profiles 30, 50 are engaged with each other. Advantageously, the axial form-fitting body 80 is also locked into the mating axial form-fitting profile 25 by the force loading of the spring assembly 95.

[0118] exist Figure 9The illustrated design arranges the axial shape-fitting body 80 merely as a safety measure for clamping the handle device 40 at the hand-held tool machine 10, preventing the handle device 40 from being completely removed from the hand-held tool machine 10. Figure 9 The components described so far are structurally identical, especially the handle device 40, which has not been modified, but alternative fixing bodies 35A or alternative handheld tool machines 10A equipped with them are provided. Instead of the mating axial shape-fitting profile 25, a mating axial shape-fitting profile 25A with a wider groove 26A about the insertion axis S is provided, and its support surface 28A has a larger distance about the insertion axis S compared to the support surface 28. Thus, although the handle device 40 can be displaced along the insertion axis S and along the retaining surface 24 after being disengaged from the clamping receiving part 42 (that is, after it is adjusted to the disengaged position L), it can only be displaced so far that the axial shape-fitting body 80 is stopped in a shape fit at one of the support surfaces of the support surface 28A. The width of the slot 26A or the mating axial shape-fitting profile 25A about the interlocking axis S is designed such that the rotational shape-fitting profiles 30, 50 can be brought into engagement and disengaged or engaged by axially shifting the handle device 40 and the handheld tool machine 10A relative to each other along the interlocking axis S via an adjustment path VS. However, the handle device 40 can only be removed from the handheld tool machine 10A when the axial shape-fitting body 80 is adjusted to the release position F, in which the axial shape-fitting body is no longer engaged with the mating axial shape-fitting profile 25A. It is understood that, alternatively to or supplementing the solution, for example, the width of the axial shape-fitting profile 81 about the interlocking axis S can also be changed so that the axial shape-fitting body 80, in the engagement position E, also has a movement clearance about the interlocking axis S in the slot 26 or the mating axial shape-fitting profile 25, which enables the rotational shape-fitting profiles 30, 50 to be brought into engagement or disengaged.

[0119] exist Figure 4In the case of the axial form-fitting body 80A shown, it can be said that the two solutions explained up to this point are combined with each other. On the one hand, the axial form-fitting body 80A, in the engaged position E, rests against the support surface 28 of the groove 26, which is furthest from the mating rotary form-fitting profile 30, with a support surface 83. Thus, even when the clamping ring 41 is adjusted to the disengaged position L, the handle device 40 is held in a form-fitting manner with respect to the insertion axis S, not only in the radial direction but also in the axial direction of the insertion axis S. The support surface 83 has a large distance to the mating rotary form-fitting profile 30 in the corresponding assembly position of the handle device 40 in the hand-held tool machine 10. Furthermore, the axial form-fitting body 80A can also be adjusted to the release position F by means of the form-fitting operating handle 90, in which it is no longer engaged in the mating axial form-fitting profile 25, so that the handle device 40 can be completely removed from the hand-held tool machine.

[0120] Furthermore, the intermediate position Z of the axial shape-fitting body 80 can be set between the engaged position E and the released position F, in which, for example, the retaining profile 81A protruding before the ramp 84 is also engaged with the mating axial shape-fitting profile 25. The retaining profile 81A is designed, for example, to retain the protrusion, particularly as a rib, ramp, or the like, which protrudes before the front face 82, but has a distance to the support surface 83 about the insertion axis. When the axial shape-fitting body 80A is adjusted to the intermediate position Z, the handle device 40 has a movement clearance about the insertion axis S such that the support surface 83A of the retaining protrusion or the retaining profile 81A can be displaced about the insertion axis S between the support surface 28 of the slot 26, thereby allowing the rotating shape-fitting profiles 30 and 50 to be brought into disengagement and into engagement, however, the handle device 40 cannot be removed from the fixed section 20 of the handheld tool machine 10.
