     BACKGROUND 
     The disclosure is based on a hand power tool according to the description below. 
     There has already been proposed a hand power-tool device, in particular for an angle grinder, having an at least substantially rod-shaped housing region that, during operation, serves as a main handle element, and having at least one operating element, which extends, on the housing region, along a direction of main extent of the housing region. 
     SUMMARY 
     The disclosure is based on a hand power-tool device, in particular for an angle grinder, having an at least substantially rod-shaped housing region that, during operation, serves as a main handle element, and having at least one operating element, which extends, on the housing region, along a direction of main extent of the housing region. 
     It is proposed that the hand power-tool device has at least one bearing, by which at least one operating face of the operating element is carried so as to be swivelable about at least one axis aligned at least substantially parallelwise in relation to the direction of main extent. In particular, a “rod-shaped housing region” is to be understood to mean a region of a housing of a hand power tool having a longitudinal extent that is at least twice as long, advantageously at least three times as long, particularly advantageously at least four times as long, as a maximum transverse extent. Preferably, the rod-shaped housing region has an at least partially rounded outer face, particularly preferably an at least substantially cylindrical outer face. Preferably, the rod-shaped housing region has, in particular, a substantially round outer cross section, on at least a plane aligned perpendicularly in relation to the direction of main extent, advantageously on a greater part of a total length. Alternatively or additionally, the housing region could have one or more outer cross sections, considered appropriate by persons skilled in the art, for example polygonal and/or elliptical outer cross sections. Preferably, the outer cross section is less than 15 cm, particularly preferably less than 10 cm. In particular, one or more housing elements can constitute the rod-shaped housing region. Furthermore, the hand power-tool device could have a plurality of rod-shaped housing regions. Preferably, the rod-shaped housing region encloses at least one function element of a hand power tool, and in particular it encloses a function element of a drive train of the hand power tool such as, for example, a motor, a transmission and/or an electronics unit. The expression “during operation” is to be understood to mean, in particular, during a work operation conducted by an operator. In particular, the term “main handle element” is to be understood to mean, in particular, an element provided to be gripped by the operator, in particular during a work operation in a confined space. “Provided” is to be understood, in particular, as specially configured. In particular, an “operating element” is to be understood to mean an element by means of which the operator influences the state of the hand power tool, advantageously a state of a motor of the hand power tool, during a work operation. Preferably, the operator influences a rotational speed of an insert tool by means of the operating element. The expression “along the housing region” is to be understood to mean, in particular, that the operating element has at least one partial face adjacent to and, in particular, separated by less than 5 mm from, the housing region. In particular, a “direction of main extent” is to be understood to mean a direction in which an element parallel to an outer contour has a maximum extent. Preferably, the housing region and/or, in particular, the operating face has a plane of symmetry aligned parallelwise in relation to the direction of main extent, over a region along the direction of main extent. Alternatively, the housing region and/or the operating face can be realized asymmetrically. A “bearing” is to be understood to be, in particular, a unit provided to exert upon the operating element a bearing force that counteracts a motion other than a swiveling motion. In particular, an “operating face” is to be understood to mean a face of the operating element upon which an operator exerts a force during an actuation. The expression “substantially parallelwise” is to be understood to mean, in particular, that an angle between the direction of main extent of the housing region and the axis is less than 30 degrees, particularly preferably less than 10 degrees. In particular, the expression “carried so as to be swivelable” is to be understood to mean that the bearing fastens the operating element such that it is rotatable about an axis, over an angular range. The configuration of the hand power-tool device according to the disclosure makes it possible to achieve comfortable operation, in particular in combination with a dead-man circuit. In particular, an actuating force and an actuating stroke of the operating element are substantially constant at differing locations along the direction of main extent of the operating element. Owing to the swivelable mounting, there is little susceptibility to jamming, this being particularly advantageous, in particular in comparison with an operating element that is moved translationally. A “dead-man circuit” is to be understood to mean, in particular, a circuit that automatically deactivates the hand tool in the case of a termination of an intended activation of the hand power tool, for example in the case of unconsciousness, and/or in the case of intentional release. 
     In a further configuration, it is proposed that the operating element has a direction of main extent aligned at least substantially parallelwise in relation to the direction of main extent of the housing region, whereby, through simple configuration, particularly comfortable and safe operation can be achieved, in particular substantially irrespective of an operator hand position along the main extent. 
     Furthermore, it is proposed that the operating element extends over at least a greater part of a total length of the rod-shaped housing region, whereby very particularly safe and comfortable operation is made possible through simple configuration. A “total length” is to be understood to mean, in particular, an extent along the direction of main extent. In particular, the expression “extend over at least a greater part of a total length” is to be understood to mean that planes aligned perpendicularly in relation to the direction of main extent intersect the housing region and the operating element on at least 50%, preferably at least 75% of the total length of the housing region. 
     Further, it is proposed that the operating face is realized in a convexly curved manner, enabling an operator to comfortably and reliably operate the operating means from differing sides. In particular, the operating element is equally suited for operation by left-handed and right-handed operators. Preferably, the operating face is convexly curved in at least one plane aligned perpendicularly in relation to the direction of main extent of the operating element. 
     Advantageously, the operating face in this plane is convexly curved on a segment of at least 10 mm, advantageously 20 mm. Preferably, the convexly curved operating face has a radius of greater than 20 mm, particularly preferably greater than 40 mm. 
     In addition, it is proposed that the hand power-tool device comprises an inhibiting device for inhibiting the operating element, having a release element that is provided to undo the inhibiting of the operating element, whereby particularly safe operation can be achieved, because the operating element can be inhibited against unintentional actuation, for transport and/or storage. An “inhibiting device” is to be understood to mean, in particular, a device that prevents at least a reaction to an actuating force acting upon the operating element, i.e. a force in an actuating direction. Advantageously, the inhibiting device prevents, in particular mechanically, an actuating movement of the operating element. Alternatively or additionally, the inhibiting device could interrupt an output of energy, in particular electrical energy, to a means that can be actuated by means of the operating element. For example, a switching unit could interrupt a supply of energy to the motor. Preferably, the release element differs haptically from the operating element and/or has advantageously differing actuating directions. An “actuating direction” is to be understood to mean, in particular, a direction in which the operating element is carried such that it can be moved from a non-actuated position into an actuated position. 
     Furthermore, it is proposed that the housing region encloses at least one free region, into which the operating element is carried such that it can be sunk, at least partially, upon an actuation, whereby, advantageously, the operating element can be operated and well protected. A “free region” is to be understood to mean, in particular, a region that is adjacent to the operating element and that, when the operating element is not actuated, is free of the operating element and, in particular, third elements. Preferably, the operating element can be actuated by being moved in the direction of the free region. In particular, “enclose” is to be understood to mean that the free region is disposed within the housing region, i.e. in particular, that the housing region encloses the free region, at least largely, on a hemisphere. 
     In an advantageous realization of the disclosure, it is proposed that the operating element, when in a non-actuated operating state, is disposed in an at least partially sunk manner in the housing region, such that the operating element is disposed in an advantageously protected manner. “Disposed in an at least partially sunk manner” is to be understood to mean, in particular, that at least 5%, advantageously at least 10% of a material of the operating element, when in a non-actuated operating state, is disposed within a face that spans a surface of the housing region, advantageously an inner face of the housing. Advantageously, at least one stop of the operating element is disposed in a sunk manner in the housing region, which stop prevents the operating element from moving completely out of the housing region. Preferably, the operating element protrudes from the housing region at a through-hole or, alternatively, at a plurality of through-holes. 
     In a further configuration, it is proposed that the bearing comprises at least one film hinge, with the result that little resource input is required for structural configuration and production costs are kept low. A “film hinge” is to be understood to mean, in particular, a hinge in which a flat, flexible material transmits a bearing force. Preferably, the film hinge is realized so as to be integral with the housing region and/or, advantageously, with the operating element. 
     Preferably, the film hinge has a flexurally soft region, which transmits substantially only tensile and/or compressive forces. 
     Furthermore, it is proposed that the bearing has at least one oblong hole, at least for guiding the operating element, thereby enabling the operating element to move, particularly advantageously, in a guided manner. An “oblong hole” is to be understood to mean, in particular, a blind hole and/or a through opening, having a non-round, preferably elongate outer form in relation to a surrounding face. 
     Further, it is proposed that the operating element has at least two operating faces carried so as to be movable relative to each other, enabling an advantageous symmetry of the operating element to be achieved. Preferably, the operating faces are carried so as to be tiltable by at least 10 degrees, preferably at least 20 degrees, in relation to each other. 
     In addition, the disclosure is based on a hand power tool having a hand power-tool device, it being the case that all hand power tools considered appropriate by persons skilled in the art, such as, in particular, drills, hammer drills, saws, planes, screwdrivers, routers, sanders, multifunction tools, garden appliances and/or, advantageously, angle grinders, would be conceivable, thereby making it possible to provide a hand power tool that is particularly comfortable to use.

     DETAILED DESCRIPTION 
       FIGS. 1 and 2  show a hand power tool  36 a according to the disclosure having a hand power-tool device  10   a . The hand power tool  36   a  is realized as an angle grinder. The hand power tool  36   a  has a weight of less than 3.5 kg, preferably less than 2.5 kg. It comprises a removable ancillary handle  38   a , an insert-tool fastening  40   a , an insert-tool guard  42   a  and a housing  44   a  . An insert tool  46   a  is fastened to the insert-tool fastening  40   a . 
     The hand power tool device  10   a  has a housing region  12   a  constituted by a surface of the housing  44   a . The housing region  12   a  is realized in the shape of a rod. During operation, it serves as a main handle element. For this purpose, the housing region  12   a  has a roundish cross section on a plane aligned perpendicularly in relation to a direction of main extent  16   a . A direction of main extent of the ancillary handle  38   a  is aligned substantially perpendicularly in relation to the direction of main extent  16   a  of the housing region  12   a . The insert-tool guard  42   a  is disposed between the insert-tool fastening  40   a  and the housing region  12   a . It protects an operator&#39;s hand as it grips the housing region  12   a.    
     In addition, the hand power-tool device  10   a  has an operating element  14   a . The operating element  14   a  extends on the housing region  12   a , along the direction of main extent  16   a  of the housing region  12   a , extending on a side of the housing region  12   a  that faces toward the insert-tool fastening  40   a . Alternatively, it could also be disposed on a side of the housing region  12   a  that faces away from the insert-tool fastening  40   a , or on another side considered appropriate by persons skilled in the art. In particular, the housing region  12   a  could be rotatable relative to the insert-tool fastening  40   a . The operating element  14   a  has a direction of main extent  24   a , which is aligned parallelwise in relation to the direction of main extent  16   a  of the housing region  12   a . The operating element  14   a  in this case extends over at least a greater part of a total length of the rod-shaped housing region  12   a . The operating element  14   a  has an operating face  20   a  having a substantially rectangular projection face. The operating face  20   a  is realized so as to be convexly curved about a center axis of the housing region  12   a  that extends along the direction of main extent  16   a  of the housing region  12   a . Disposed between the operating element  14   a  and the housing  44   a  there is a sealing lip, not represented in greater detail, or other overlapping element, by means of which the housing  44   a  is protected against the ingress of dirt. The sealing lip or the overlapping element is fastened to the housing  44   a.    
     The hand power-tool device  10   a  has a bearing  18   a , by which the operating face  20   a  of the operating element  14   a  is carried so as to be swivelable, relative to the housing region  12   a , about an axis  22   a  aligned parallelwise in relation to the direction of main extent  16   a  of the housing region  12   a . For this purpose, the housing region  12   a  comprises a free region  30   a , into which the operating element  14   a  is carried such that it can be partially sunk upon an actuation. The hand power-tool device  10   a  comprises a spring element, not represented in greater detail, which effects a force upon the operating element  14   a , which force is provided to swivel the operating element  14   a  out of the free region  30   a  upon termination of an actuation. When in a non-actuated operating state, the operating element  14   a  is disposed so as to be at least partially sunk in the housing region  12   a , at least a stop  48   a  of the operating element  14   a  being disposed in a sunk manner. The stop  48   a  prevents the operating element  14   a  from being swiveled completely out of the housing region  12   a  by the spring element. 
     As shown by  FIGS. 3, 4 and 5 , the bearing  18   a  comprises two studs  50   a ,  52   a  and two recesses  54   a ,  56   a . One of the studs  50   a  is formed on to the operating element  14   a , on a corner  58   a  of the operating element  14   a  that faces toward the insert-tool fastening  40   a . The associated recess  54   a  is formed on to the housing  44   a , on a side of the housing region  12   a  that faces toward the insert-tool fastening  40   a . The other recess  56   a  is formed on to the operating element  14   a , on a corner  60   a  of the operating element  14   a  that faces away from the insert-tool fastening  40   a . The associated stud  52   a  is formed on to the housing  44   a , on a side of the housing region  12   a  that faces away from the insert-tool fastening  40   a . Alternatively, studs and/or recesses of the bearing  18   a  could be constituted by discrete units or materials; for example, a metallic stud, in particular a steel stud, could be pressed a recess in the housing  44   a  and/or in the operating element  14   a  and carried with rotational play in the respectively other component. 
     The corners  58   a ,  60   a  in this case are disposed between an edge  62   a  of the operating element  14   a  that is aligned parallelwise in relation to the direction of main extent  16   a  and, respectively, an edge  64   a  that is aligned perpendicularly in relation to the direction of main extent  16   a  and perpendicularly in relation to a rotational axis  66   a  of the insert-tool fastening  40   a . The two corners  58   a ,  60   a  in this case are located on the same side of the operating element  14   a , as viewed in the direction of main extent  16   a , it being irrelevant for operation whether the corners  58   a ,  60   a  are disposed on the left or on the right. The axis  22   a  of the bearing  18   a  is thus disposed at a distance from a plane that is spanned by the rotational axis  66   a  of the insert-tool fastening  40   a  and the direction of main extent of the housing region  12   a.    
     During assembly, the operating element  14   a  is fastened by a fastening directed on to the insert-tool fastening  40   a . In this case, one of the studs  50   a ,  52   a  penetrates, respectively, into one of the recesses  54   a ,  56   a . The axis  22   a  of the bearing  18   a  extends through the two studs  50   a ,  52   a . In addition, the bearing  18   a  could have further bearing elements, in particular between the studs  50   a ,  52   a , and the recesses  54   a ,  56   a.  Alternative arrangements of the studs and recesses that are considered appropriate by persons skilled in the art are possible. Further, a film hinge between the operating element  14   a  and the housing  44   a  would be possible. 
     The housing  44   a  has a housing element  68   a , which fastens a motor  70   a  of the hand power tool  36   a . In addition, the housing  44   a  has a housing element  72   a , which fastens an electronics unit  74   a  of the hand power tool  36   a . This housing element  72   a  is realized as two shells. One shell thereof is represented in  FIG. 3 . The housing element  68   a  that fastens the motor  70   a  has one of the studs  52   a  and one of the recesses  54   a . This housing element  68   a  therefore carries the operating element  14   a . The housing element  72   a  that fastens the electronics unit  74   a  prevents the operating element  14   a  from moving along the direction of main extent  16   a , when in an assembled state. As a result, the studs  50   a ,  52   a  are held in the recesses  54   a ,  56   a.    
     The hand power-tool device  10   a  has an actuation pickup  76   a . Upon an actuation, the actuation pickup  76   a  generates an electrical characteristic quantity, which contains at least information relating to the actuation. It comprises the spring element, not represented in greater detail, a lever  78   a  and an electrical switching component  80   a . The lever  78   a  is carried so as to be movable about an axis  82   a  and, upon an actuation, converts a movement of the operating element  12   a  in a manner suitable for the switching component  80   a.    
     The hand power-tool device  10   a  has an inhibiting device  26   a , which is represented in greater detail in  FIGS. 4 and 6 .  FIG. 4  shows the the operating element  14   a  in a non-actuated state and the inhibiting device  26   a  in an inhibiting state.  FIG. 6  shows the operating element  14   a  in an actuated state and the inhibiting device  26   a  in a non-inhibiting state. The inhibiting device  26   a  has a release element  28   a  and a stop  84   a . The release element  28   a  is carried, on the operating element  14   a , so as to be swivelable. It is disposed centrally on the operating element  14   a . The stop  84   a  is formed on to the housing  44   a . When the release element  28   a  is in an inhibiting configuration, the release element  28   a  supports on the housing  44   a  an actuating force acting upon the operating element  14   a.    
     The hand power-tool device  10   a  comprises a switch-on locking mechanism  86   a , represented only in  FIGS. 1 and 7 . The switch-on locking mechanism  86   a  has an operating means  88   a , a spring element  90   a  and a latching means  92   a . The operating means  88   a  is carried so as to be movable perpendicularly in relation to an actuating direction  94   a  of the operating element  14   a . The spring element  90   a  effects a restoring force upon the operating means  88   a . When the operator has actuated the operating element  14   a , he can move the operating means  88   a , against the spring element  90   a , into a latching position represented in  FIG. 7 . In the latching position, the operating means  88   a  latches into the operating element  14   a , by means of the latching means  92   a . When in a latched-in state, the switch-on locking mechanism  86   a  prevents the operating element  14   a  from moving back into a non-actuated initial position, even if the operator does not exert any actuating force upon the operating element  14   a . If the operator moves the operating element  14   a , in a latched-in state, in the actuating direction  94   a , the latching of the latching means  92   a  opens and the spring element  90   a  moves the operating means  88   a  into a non-locking position, not represented in greater detail. 
     During a parting operation, the operator holds the housing region  12   a , advantageously by gripping with the left or the right hand, along the direction of main extent  16   a , in a central region, or in a front region facing toward the insert-tool fastening  40   a . The operator in this case uses either the ball of the hand or the thumb to actuate the operating element  14   a . During overhead working, the operator advantageously holds the housing region  12   a  at a rear region that faces away from the insert-tool fastening  40   a . During surface working, i.e. when the insert tool  46   a  is aligned approximately parallelwise in relation to a surface that is to be worked, the operator advantageously uses the tip of the finger opposite the thumb to actuate the operating element  14   a.

The following descriptions and the drawings are limited substantially to the differences between the exemplary embodiments and, in respect of components having the same designation, in particular in respect of components having the same references, in principle reference may also be made to the drawings and/or the description of the other exemplary embodiments, in particular of  FIGS. 1 to 7 .

The housing  44   b  constitutes a rod-shaped housing region  12   b , which, during operation, serves as a main handle element. The housing  44   b  has a pot-shaped housing cover  96   b , and has a housing element  68   b  provided to fasten a motor, not represented in greater detail. The housing  44   b  fastens the operating element  14   b . The operating element  14   b  extends, on the housing region  12   b , along a direction of main extent  16   b  of the housing region  12   b . In addition, the hand power-tool device  10   b  has a bearing  18   b .

As an alternative to the pot-shaped housing cover  96   b , the operating element  14   b  could also be carried in a housing element, not represented in greater detail, provided to fasten a transmission. 
     The hand power-tool device  10   b  comprises an actuation pickup  76   b  having a switching component  80   b . The actuation pickup  76   b  is provided to directly actuate the switching component  80   b  upon a movement of the operating element  14   b  in the actuating direction  94   b.

During operation, the housing region  12   c  serves as a main handle element. The operating element  14   c  extends, on the housing region  12   c , along a direction of main extent  16   c  of the housing region  12   c . It has two operating faces  20   c . The bearing  18   c  carries the operating face  20   c  of the operating element  14   c  so that it can be swiveled and in addition tilted, respectively, about an axis  22   c  aligned parallelwise in relation to the direction of main extent  16   c . The axes  22   c  are disposed at a distance from the hand power-tool device  10   c.    
     The bearing  18   c  has oblong holes  34   c ,  35   c  for the purpose of guiding the operating element  14   c . The oblong holes  34   c ,  35   c  are disposed on a housing  44   c  of the hand power tool, being disposed on two sides of a free region  30   c  of the housing  44   c , a represented side facing toward an insert-tool fastening of the hand power tool, and a non-represented side facing away from the insert-tool fastening. Two of the represented oblong holes  34   c  are disposed in a mirror-symmetrical manner in relation to a symmetry plane  98   c  that extends through the third oblong hole  35   c  represented. These two oblong holes  34   c  guide, respectively, one of the two operating faces  20   c  substantially perpendicularly in relation to the symmetry plane  98   c . The third oblong hole guides both operating faces  20   c  equally in a direction parallel to the symmetry plane  98   c . The bearing has a film hinge  32   c , which carries the two operating faces  20   c  of the operating element  14   c  movably in relation to each other. It is possible to have between the operating faces  20   c  an alternatively realized bearing, considered appropriate by persons skilled in the art. 
       FIG. 11  shows a further exemplary embodiment of a switch-on locking mechanism  86   d  of a hand power-tool device  10   d  having an operating element  14   d . The switch-on locking mechanism  86   d  has an operating means  88   d , a spring element  90   d  and a latching means  92   d . The operating means  88   d  is carried so as to be movable about an axis  100   d , which is aligned perpendicularly in relation to the axis  22   d  of the operating element  14   d . The spring element  90   d  effects a restoring force upon the operating means  88   d . When the operator has actuated the operating element  14   d , he can move the operating means  88   d  of the switch-on locking mechanism  86   d , against the spring element  90   d , into a latching position. 
       FIG. 12  shows a further exemplary embodiment of a hand power-tool device  10   e , having an operating element  14   e , which has two operating faces  20   e  that are carried movably in relation to each other. The two operating faces  20   e  are mounted such that they can be swiveled, respectively, about an axis  22   e . One of the operating faces  20   e  has an opening  102   e , into which a portion of another of the operating faces  20   e  can be sunk upon an actuation of the operating element  14   e.    
       FIG. 13 , in an exploded representation, shows a further exemplary embodiment of a hand power-tool device  10   f , having a rod-shaped housing region  12   f , an operating element  14   f  and a bearing  18   f . The bearing  18   f  has a rod  104   f , which extends along an axis  22   f  of the bearing  18   f . The housing region  12   f  and the operating element  14   f  have openings  106   f , through which the rod  104   f  extends when in an assembled operating state. The rod  104   f  in this case carries the operating element  14   f  such that it can be swiveled relative to the housing region  12   f.
