Definitions
- the invention relates to a handle device for releasable attachment to a hand machine tool, in particular a drill or screwdriving machine, the handle device having a clamping ring with a clamping receptacle for receiving a fastening section, in particular a machine neck, the hand machine tool and a handle, which protrudes from the clamping ring and is intended and designed for gripping and / or for gripping by an operator, the clamping receptacle between a clamping position that clamps the fastening section of the hand-held machine tool, in which a Inner circumferential surface of the clamping receptacle rests in a press fit on the fastening section of the hand machine tool, and a release position that releases the fastening section of the hand machine tool is adjustable, in which the fastening section of the hand machine tool into the clamp m receptacle can be inserted along a plug-in axis, and wherein the handle device has a movably with respect to the clamping recept
- a handle device of this type is described, for example, in DE 3829801 A1.
- the handle device has a sleeve with a so-called Arre animal nose as an axial form-fitting contour, which engages in a groove on the spindle neck of the hand machine tool by adjusting the clamping receptacle in the clamping position.
- the clamping receptacle enables a frictional, clamping hold of the handle device on the hand machine tool.
- As an additional axial form-fitting locking or fixing with respect to the plug-in axis is used by the axial form-fitting contour.
- the clamping seat To adjust the handle device with respect to the hand machine tool, for example with respect to the rotational position with respect to the plug-in axis and / or to release the handle device, the clamping seat must be released by moving the clamping receptacle into the release position during an initial rotary actuation section of a handle. In addition, the axial form fit must also be canceled by means of an adjoining rotary actuation section of a handle.
- a handle device of the type mentioned has a separate from the clamping actuating handle and manually operated by the operator independently of the clamping actuating handle form-locking actuating handle for adjusting the Axialform circuit body between an engagement position in which the The axial form-locking contour is in engagement with the counter-axial form-locking contour and the handle device is positively locked with respect to the plug-in axis on the fastening section of the hand-held power tool, and has a release position in which the axial form-locking contour is out of engagement with the counter-axial form-locking contour and the hand-held power tool and the holding device are displaceable relative to one another with respect to the quick-release axle.
- a basic idea here is that the clamping ring with the clamping actuation handle can be adjusted between the clamping position and the release position and the axial form-fitting contour can be actuated independently and / or separately from the clamping actuation handle or the clamping ring using the form-fitting actuation handle. So there are two independent and / or separately manually operable operating handles IN ANY of each other.

- the axial form-fitting contour in the engagement position protrudes further in front of the inner circumferential surface of the clamping receptacle than in the release position.
- the axial form-fitting contour in the release position does not protrude in front of the inner circumferential surface of the clamping receptacle and / or is aligned with the inner circumferential surface and / or is set back behind the inner circumferential surface of the clamping receptacle.

- a concept shown in FIG. 9 provides that the axial form-fitting body 80 is only provided as an additional safety measure for clamping the handle device 40 on the hand machine tool 10, which only prevents the handle device 40 from being completely removed from the hand machine tool 10.
- elements previously described are structurally identical, in particular the handle device 40 is not modified, while an alternative fastening body 35A or an alternative hand machine tool 10A equipped with it are provided.

- the width of the groove 26A or counter-axial form-locking contour 25A with respect to the plug-in axis S is dimensioned such that the rotational form-locking contours 30, 50 are disengaged by an axial displacement of the handle device 40 and the hand machine tool 10A along the plug-in axis S relative to one another by an adjustment path VS. can be brought into engagement, but the handle device 40 can only be removed from the hand machine tool 10A when the Axialform gleichkör is adjusted by 80 in the release position F, in which it no longer engages in the opposite axial form-locking contour 25A.
- a width of the axial shape Closing contour 81 is changeable with respect to the plug-in axis S, so that the axial form-locking body 80, for example, also in the groove 26 or counter-axial form closing contour 25 in the engagement position E has a play in relation to the plug-in axis S, which makes it possible to engage the rotationally form-fitting contours 30, 50 or disengage.
- an axial form-locking body 80A shown in FIG the hand grip device 40 has on the hand machine tool 10, on the support surface 28 of the groove 26 furthest away from the counter-rotational interlocking contours 30 and thus a form-fitting hold of the handle device 40 on the even when the clamping ring 41 is moved into the release position L.
- Hand machine tool 10 is implemented in both the radial and axial directions of the quick-release axis S with respect to the plug-in axis S.
- the axial form-fitting body 80A can also be adjusted into the release position F using the form-fitting actuating handle 90, in which it no longer engages the counter-axial form-fitting contour 25, so that the handle device 40 can be completely removed from the hand machine tool .

- the holding contour 81 A is designed, for example, as a holding projection, in particular as a rib, a sloping surface or the like, which protrudes in front of the front surface 82, but is at a distance from the support surfaces 83 with respect to the plug-in axis.
- the handle device 40 When the axial interlocking body 80A is adjusted into the intermediate position Z, the handle device 40 has a play with respect to the plug-in axis S such that the support surfaces 83A of the retaining projection or the holding contour 81 A between the support surfaces 28 of the groove 26 can be displaced with respect to the plug-in axis S. so that the rotationally interlocking contours 30 and 50 can be disengaged and brought into engagement, but the handle device 40 cannot be removed from the fastening section 20 of the hand machine tool 10.
