Abstract

The hand-held machine tool (10) has a hook arrangement (28) with two hook arms (29a), which are movably supported on the housing (18) and which are assigned opposing housing walls (27a) of the housing. The hook arms are movably coupled such that the hook arm is moved away from its assigned housing wall by the movement of the other hook arm to its assigned housing wall.

Description

The invention relates to a hand-held machine tool, in particular a screwdriver and / or drill, with a housing, a drive motor and a drivable by the drive motor tool holder for receiving a particular designed as a drilling or screwing tool, and arranged on the housing hook arrangement for Hooking the hand-held machine tool on a counter-stop, for example on the clothing of an operator.

Such a hand-held power tool is, for example, in the non-prepublished German patent application DE 10 2009 024 112 displayed. With the help of the hook arm, which may also be referred to as a retaining clip, an operator can hang the hand-held machine tool, for example on a piece of clothing, in particular a belt, a bag or the like. Thus, therefore, the hand-held machine tool is easy to handle due to the holding clips or hook, in particular transportable.

The respective hand-held machine tool can only be mounted in a single position on the counter-stop, namely in that in which the hook is available. For example, by a tool attached to the hand-held machine tool, a screw magazine or the like, situations are possible in which the hand-held machine tool is not or only under difficult conditions can be attached to the counterhold. For example, depending on the location of the respective hook an unfavorable center of gravity may be present, which makes handling extremely difficult.

It is therefore the object of the present invention to provide a hand-held power tool with a convenient handling enabling hook assembly.

To solve the problem is provided in a hand-held power tool of the type mentioned that the hook assembly comprises a first hook arm and a second hook arm, which are associated with each other opposite first and second housing walls of the housing and movably mounted on the housing, and that the first hook arm and the second hook arm are coupled in such a manner that the other hook arm is moved away from the housing wall assigned to it by moving the one hook arm to the housing wall assigned to it, and / or vice versa.

A force that exerts the one hook arm on the other hook arm in the context of motion coupling, for example, a compressive force or a tensile force or both, especially when the hook arms are firmly coupled together.

A basic idea of the invention is that two hook arms are provided, so that the hand-held machine tool can be fastened to a counterhold at different locations, namely at the location of the respective hook arm. For example, the housing walls side walls of the housing so that right and left or front and rear each have a hook for convenient attachment of the hand-held machine tool to a counter-support is available. However, the invention goes one step further by namely the movement of the two hook arms. This makes it possible to have a hook arm from Housing away, to operate the other hook arm towards the housing in a single simultaneous movement.

In principle, it would be conceivable that the hook arms are not coupled and each hook arm is independent of the other movable, which would represent a self-inventive concept. By the movement coupling, however, it is possible that, for example, a hook arm in a Einhakstellung which is provided for hooking on the counter-support is moved, while the other hook arm is moved to a non-use position, which is not intended to be hooked to a counter-stop. The unneeded, located in the non-use position hook arm is closer to the housing so that it does not bother.

Preferably, the unneeded, in non-use position hook arm is directly on, in particular flat against the housing positioned. Thus, therefore, the hook arm in non-use position has a smaller distance to the housing wall assigned to it than the hook arm located in Einhakstellung.

It is preferred if the first and the second hook arm are fixedly coupled together by a coupling device. It is understood that, alternatively, a coupling gear or a driving can be provided, so that the first hook arm carries with it the other, second hook arm or vice versa.

The aforementioned preferred embodiment expediently provides that the first and second hook arm and the coupling device are firmly connected to one another, for example in one piece.

The first and second hook arm, for example, hook arms, the coupling means a base leg of a substantially U-shaped hook member, such as a bracket. It is preferred if the first and / or second hook arm extend obliquely inclined away from the base leg.

The oblique inclination can for example be made such that the respective hook arm is inclined obliquely in the sense of a greater distance of its free end than its end connected to the base leg - which facilitates hooking - or vice versa, which has a better grip on the backing result.

But it is also possible and realized in the embodiment so that at least one of the hook arms has an oblique inclination such that it is inclined, for example, with respect to a plane in which the base leg and from which it protrudes, for example, in the bottom region of the housing extending plane runs, for example, to a front or a rear side of the housing.

It is preferred if the first and / or second hook arm each have at their free ends an insertion bevel for insertion on the counter-stop. This facilitates handling.

The base leg of the hook arrangement is expediently arranged on an underside or bottom side of the housing, so that the first and the second hook arm run alongside housing side walls.

It is preferred if the first hook arm and / or the second hook arm and / or the hook arrangement as a whole, for example the aforementioned hook element, consist of metal, for example of steel. It goes without saying that plastic, in particular fiber-reinforced plastic, as a base material for a hook arm or the hook assembly as a whole in question.

It is preferred if the first and / or second hook arm are resilient relative to their associated housing wall. The respective hook arm has, for example, a spring tension towards the respective housing wall.

It is preferred if the hook assembly is releasably attachable to the housing, in particular fastened without tools. This is particularly simple when a plug-in receptacle or a plug-in projection for the hook arrangement is present, so that it can be attached to the housing. For example, a plug-in receptacle is provided for the coupling device, into which it can be inserted. In principle, it is also possible to insert individual hook arms in corresponding plug receptacles. The plug-in receptacle can form or have a sliding bearing for the hook arrangement. Preferably, the plug-in receptacle is provided with a plug-in coding, so that the hook arrangement can be inserted only in a single position, expediently a middle position. When the first and / or the second hook arm are moved away from this central position, it projects in front of the housing wall assigned to it, so that it is ready for hooking to a counterhold. Thus, the plug-in receptacle at the same time still has a holding function, namely that the respective hook arm from the plug-in receptacle can not be moved out, if he takes the aforementioned, intended for hooking on the counterhold Einhakstellung.

Although it would be possible in principle to provide pivotable or movable hook arms. However, it is preferred if the first and / or second hook arm are mounted on a slide bearing displaceable on the housing.

The coupling device forms, for example, a bearing section displaceably guided on the sliding bearing of the hook arrangement. It is understood that the hook arms may also slide bearings on sections to be performed on the sliding bearing. This is the case in particular when the first and second hook arm are separate units from each other.

The sliding bearing advantageously has a guide channel for guiding a bearing section of the hook arrangement. An insertion opening of the guide channel, which is provided for insertion or removal of the hook assembly, expediently has an inner contour, which correlates with an outer contour of the bearing portion of the hook assembly in such a way that the hook assembly can be inserted only in the region of an insertion longitudinal position in the guide channel. This insertion longitudinal position is, for example, a center position, in which the first and second hook arm are approximately equidistant from the housing wall assigned to it in each case.

Neither the first nor the second hook arm have in the insertion longitudinal position, for example, provided for a comfortable operation in itself hooking distance or a Einhakstellung. Advantageously, it is then provided that the hook arrangement is displaced into a longitudinal position away from the insertion longitudinal position, for example the central position, so that the hook arrangement is held captive in the guide channel. The inner contour of the guide channel and / or the outer contour of the bearing section expediently have holding projections in order to keep the bearing section of the hook arrangement in the guide channel away from the insertion longitudinal position.

These holding projections are expediently arranged on the respective end regions of the guide channel or of the bearing section. It is preferred if the retaining projections are provided approximately in corner regions of a triangle, particularly preferably a quadrangle in the respective longitudinal end regions, which allows a good grip of the hook arrangement in the guide channel. The holding projections serve advantageously to transfer loads or forces of the hook assembly on the housing, which arise through the use of the hook assembly.

The hand-held power tool expediently has latching means for latching the first or second hook arm at a respective distance from the housing wall associated therewith. The rest distance is, for example, the aforementioned hooking distance or the non-use distance. Thus, therefore, the locking means in the hooking or non-use position are effective.

It is preferred if the locking means are provided on the coupling device, for example on the base leg.

The locking means advantageously comprise at least one arranged on the hook arrangement, resilient or spring-loaded latching projection for engagement in a latching recess. The recess is conveniently located on the housing. It is understood that the latching means - also in conjunction with a latching projection on the hook assembly, and at least one latching projection provided on the housing may have, which engages in a latching recess on the hook assembly.

When the respective locking projection, it is advantageous if it is integral with the component, for example with the housing or the hook assembly, on which it is arranged. It is understood that the locking projection also, for example, by a spring-loaded ball or another spring-loaded form-fitting element may be formed.

The hook arrangement as a whole or else the first and / or second hook arm are expediently lockable by means of a bolt on the housing. In this case, it is preferred if the hook arrangement or the first or second hook arm are also movable in terms of mobility relative to the housing, in particular when they are locked by the latch or latches on the housing, i. in the respective locked position. However, it is also possible in principle that a bolt which performs the locking function forms part of a clamping means or clamping means and clamps in the locked position, the first hook arm, the second hook arm or the hook assembly as a whole in their respective position.

At this point it should be mentioned that overall advantageous clamping means for clamping the first and / or second hook arm or the hook assembly can be provided as a whole in a respective distance to the him or her associated housing wall. However, this is not the case in the later presented embodiment.

If a bolt is present, it is advantageous in a respective locking arm or the hook assembly as a whole locking locking position and / or locked in a release position in which the hook arm or the hook assembly is released, for example, for removal from the housing.

The bolt advantageously has a mushroom-like projection which is held in the housing. The arrangement is suitably made such that the bolt is held captive on the housing. This is of course possible with other means than with the aforementioned mushroom-like projection.

The hook arrangement expediently has an insertion opening for the bolt, for example in the region of the coupling device or else at another point, through which the bolt can be pushed through in its release position for removing the hook arrangement from the housing or for attachment to the housing. The insertion opening is preferably a central insertion opening, which is arranged for example in the middle of the coupling device, in particular in the middle of the base leg of the U-shaped hook element. The insertion opening preferably has a matching to the outer contour of the bolt inner contour. If the bolt is adjusted, for example, twisted or shifted, the hook assembly is no longer attachable to the bolt, so that it is inserted through the through-hole.

The bolt is in the locking position in front of the insertion opening, for example with an operating area. Although a tool-free operation is possible in principle here. It is preferred, however, if an actuating region of the bolt is to be actuated with a tool, for example a coin or a screwdriver, so that it can not be inadvertently moved from its locking position into its unlocked position.

An advantageous embodiment of the invention provides that the bolt can be pushed through the insertion opening only in the insertion longitudinal position of the hook arrangement with respect to the guide channel. If the hook assembly is longitudinally displaced with respect to this insertion longitudinal position, ie, away from it, the bolt acts as a locking element, regardless of its respective position, in particular rotational position. The bolt expediently holds the hook arrangement in connection with, for example, the abovementioned retaining projections of the inner contour of the guide channel in the guide channel.

The hand-held power tool is preferably a screwdriver and / or a power drill. The hand machine tool may be mains powered or battery operated in a preferred embodiment of the invention.

It is understood that a hook arrangement according to the invention can be arranged on a base housing of the hand-held machine tool, in which the drive motor is accommodated. However, it is also possible for the hook arrangement to be arranged on an additional housing which can be detachably fastened to the basic housing, for example a battery or rechargeable battery housing.

It is possible that the hook arrangement, in particular the coupling device, is arranged on the outside of the housing such that it passes through the housing or that it is arranged between the basic housing and the additional housing.

Advantageously, the hook arrangement according to the invention is attached to a heavy area, e.g. in the range of a rechargeable battery or the like, of the housing, in particular of the additional housing. The hook arrangement, in particular the coupling device, is preferably located on a bottom region of the respective housing.

In the hand-held power tool 10 shown in the drawing is a screwing machine 11 with an output shaft 13 driven by a schematically indicated drive motor 12. On the output shaft 13, for example, a chuck for holding a drilling tool can be arranged.

The free end of the output shaft 13 also has directly a tool holder 14 into which a schematically indicated screwing 15, such as a screwdriver bit, can be inserted.

In the present case, the hand-held power tool 10 is a cordless power tool, wherein the accumulator (not shown) is arranged in an additional housing 17 that can be detachably fastened to the base housing 16. The basic housing 16, in which the drive motor 12 is accommodated, and the additional housing 17 form a housing 18 as a whole, as in FIGS FIGS. 1 . 2 shown.

The basic housing 16 has a handle region 19 with a pressure switch 20 for switching on and off the hand-held power tool 10 and, moreover, for setting the speed of the drive motor 12. The handle portion 19 and the drive motor 12 receiving drive portion 21 of the base housing 16 are at an angle to each other, so that a total of a gun-like arrangement is made. Also approximately parallel to the handle portion 19 also extends a front protection area 22, which is connected on the one hand to the drive portion 21 and on the other hand via a connecting portion 23 on the drive portion 21 opposite side of the base housing 16 with the handle portion 19. Between the handle portion 19 and the connecting portion 23 a penetration for grasping with one hand is present.

The connecting portion 23 forms, so to speak, a support base for the additional housing 17, which is arranged in the drawing below at the connecting portion 23 of the base housing 16. The additional housing 17 is replaceable, namely, when a respective accumulator is used up and must be recharged. The solvents or bonding agents required for this purpose are not described in more detail, but are familiar to the person skilled in the art.

The additional housing 17 has a substantially cubic shape, with corner and edge regions are ergonomically rounded, which is incidentally also the case 16 of the case.

The additional housing 17 has a bottom wall 24 and a top wall 24 opposite the top wall 25, which in turn abuts substantially flat on the connecting portion 23 when the additional housing 17 is fixed to the base housing 16. Between the walls 24, 25 extend short narrow side walls 26 and between the narrow side walls 26 extending, side walls forming housing walls 27a, 27b. The two narrow side walls 26 form, for example, a front and a rear wall of the additional housing 17, while the housing walls 27a, 27b are longitudinal wall sides of the additional housing 17.

The auxiliary housing 17 forms a support base for a hook assembly 28 arranged thereon with a first hook arm 29a and a second hook arm 29b, which are associated with the housing walls 27a, 27b. The hook arms 29 are coupled together by means of a coupling device 30, in the embodiment firmly coupled together.

The coupling device 30 is formed by a base leg 31 of a hook element 32, the side arms of which form the two hook arms 29a, 29b.

The base leg 31, thus also the coupling device 30, runs along the bottom wall 24 of the additional housing 17.

The base leg 31, like the two hook arms 29a, 29b, has a wall-like, plate-like shape.

The two hook arms 29a, 29b are substantially rectangular with respect to one of the bottom wall 24 flat associated flat side 51 from.

The base leg 31 has a transverse length between the hook arms 29a, 29b, which is greater by a distance 33 than a transverse width 34 of the bottom wall 24. The distance measure 33 makes it possible, such as in FIG. 2 shown to bring the hook arm 29b in a Einhakabstand 35 with respect to the adjacent to him housing wall 27b. The other hook arm 29a, however, has in the in FIG. 2 shown position of the hook member 32 a non-use distance 36 to its associated housing wall 27a. In the non-use distance 36, the hook arm 29a lies at least in sections flat against the housing wall 27a.

But now the hook element 32 does not have to be in the in FIG. 2 shown position, in which substantially the hook arm 29b for hooking on a counter-stop, for example, the belt of a user, arranged next to the housing wall 27a and thus advantageously usable. The hook element 32 is adjustable from the first longitudinal position 37 shown in solid lines in a second longitudinal position 38 shown with dashed lines.

The hook assembly 28 is slidably mounted by means of a sliding bearing 39 with respect to the housing 18, specifically the additional housing 17. The sliding bearing 39 is arranged on the bottom wall 24 and comprises a guide channel, in which the base leg 31 is displaceably guided, so that it forms a bearing portion 73 of the hook assembly 28 insofar.

In an approximately between the two longitudinal positions 37, 38 centrally arranged insertion longitudinal position 41, shown in the FIGS. 7a, 7b , the hook member 32 may be inserted into the guide channel 40. An outer contour 42 then fits through an inner contour of an insertion opening 44 of the guide channel 40. The outer contour 42 extends between the side arms or hook arms 29a, 29b on longitudinal narrow sides of the base leg 31.

The hook element 32 as a whole is expediently designed as a stamped and bent part, whereby the outer contour 42 can be formed in a simple manner by corresponding punching.

The outer contour 42 comprises two arranged on the narrow sides of the base leg 31 and thus opposite each other, present contoured contour sections 52, the course correlate with contour portions 53 facing each other overreaching portions 54 of the guide channel 40. The contour sections 52 each comprise a center projection 45, which is arranged approximately in a longitudinal center between the two hook arms 29a, 29b. The center projection 45 is disposed between two guide portions 46. The center projection 45 and the two guide portions 46 are approximately the same length. The center projection 45 protrudes outward in front of the two guide portions 46.

Between the guide portions 46 and the hook arms 29a, 29b, a recess 55 and a retaining projection 47 is still provided, the free end is aligned approximately with the free narrow side of the guide portion 46.

The center projection 45 is assigned a center recess 48 of the inner contour 43. The middle recess 48 is adjoined in each case by a guide region 49, which is assigned to the guide region 46 of the outer contour 42. At the respective longitudinal end regions, ie close to the hook arms 29a, 29b, a holding projection 50 is still present. The four retaining projections 50 provided at the longitudinal end regions of the guide channel 40 fit in the insertion longitudinal position 41 (FIG. FIGS. 7a, 7b ) by the corresponding recesses 55 on the hook element 32. The same applies to the center projections 45, which can be pushed through the center recesses 48.

If now the hook member 32 from the middle, the insertion longitudinal position 41 in the first or second longitudinal position 37 or 38 is adjusted, such as in FIG. 7c shown, the retaining projections 50 engage over the guide portions 46. In addition, the center projections 45 dive under the guide portions 49 of the inner contour 43, so that there is a firm grip. At the respective other longitudinal end region, the retaining projections 50 engage over the retaining projections 47 so that a firm hold of the hook element 32 with respect to the housing 18 is ensured overall, both in the middle section of the base leg 31 and at its longitudinal end regions.

In the first and second longitudinal position 37, 38 latching projections 56 of locking means 57 engage in latching recesses 58, so that the hook assembly 28 is latched in the longitudinal positions 37, 38 and held there. The latching projections 56 are arranged on spring tongues 59, which are located on the base leg 31 of the hook element 32. The spring tongue 59 are punched out of the flat side 51. The locking recesses 58, however, are provided on the bottom wall 24 recesses.

The overlapping portions 54 are from side walls 60 of the guide channel 40, on the inside of the hook assembly 28 with the outer contour 42, in particular the protruding center projection 45 slides along and is thus guided laterally. The two overlapping portions 54 face each other. The overlapping portions 54, the side walls 60 and the bottom wall 24 define guide grooves 61 in which the hook member 32 is guided and received.

The hook element 32 is detachably mountable on the housing 18, so that it can be used, for example, when changing an additional battery housing 17 against another additional housing 17. The hook assembly 28 is provided with a latch 62 on the auxiliary housing 17 lockable. The latch 62 is rotatably mounted on the housing 18, specifically the additional housing 17.

A bearing portion 63 of the bolt 62 passes through a suitably provided between two housing parts 64 of the additional housing 17 bearing opening (not visible). The additional housing 17 is formed from two presently designed as half shells housing parts 64, so that when mounting the two housing parts 64 to each other, for example, welding, screwing or the like, at the same time the bolt 62 can be inserted into the bearing opening between the housing parts 64. Thus, a simple installation is possible.

By way of example, the bearing section 63 is substantially cylindrical, wherein recesses or recesses may be provided as in the exemplary embodiment.

The bearing section 63 extends between an actuating region 66 which provides an actuating region 65 and an abutment region 67 which is supported on the additional housing 17 and which comprises an abutment plate 68. The abutment plate 68 is designed like a mushroom and has on its side facing the bearing portion 63 locking projections 69 which cooperate in associated recesses on the inside of the additional housing 17. The latching projections 69 latch in a locking position V (FIG. FIGS. 7b, 7c ) in the recesses. In addition, it is advantageous if the latching projections 69 also engage in the release position F provided for removing the hook element 32 with the non-visible latching recesses on the inside of the bottom wall 24, so that removal or attachment of the hook element 32 on the additional housing 17 is simplified.

In the release position F, an outer contour of the actuating plate 66, which in the present case is substantially rectangular, fits. exactly to an inner contour of an existing on the hook assembly 28 through opening 70, which therefore therefore has a substantially rectangular inner contour. The longer side of the insertion opening 70 extend approximately parallel to the contour section 52. As in Figure 7a shown, the hook member 32 is inserted into the guide channel 40 when the latch 62 is in its release position F. If the latch 62 is rotated into its locking position V, in the present case by 90 °, the actuating plate 66 engages over the base leg 31, ie the actuating plate 66 projects outwardly beyond the through-opening 70, which contributes to an additional retention of the hook element 32 on the additional housing 17.

For turning the bolt 62, a slot 71 is expediently provided on the actuating region 65, for example for a coin or a screwdriver. Overall, however, it is advantageous if the bolt 62 without tools or, for example, with the coin operated.

The slot-like configuration of the through opening 70 makes it possible to move the hook element 32 between the two longitudinal positions 37, 38 along the sliding bearing 39. Both in the longitudinal positions 37, 38 and in the insertion longitudinal position 41, the bolt 62 engages in its locking position V, the hook assembly 28 so that it is held captive on the additional housing 17.

The additional housing 17 is relatively heavy due to the accumulators arranged therein. It is therefore advantageous to arrange the hook arrangement 28 according to the invention there, ie in a relatively heavy area of a respective housing of a hand-held machine tool according to the invention.

The hook arms 29a, 29b are inclined away from the housing walls 27a, 27b at their free ends, so that insertion slopes 72 are formed there.

The hook element 32 is located approximately in a rear region of the additional housing 17, i. approximately below the handle portion 19. The hook arms 29a, 29b are obliquely forward, i. in the direction of the protective region 22 obliquely inclined from the base leg 31 from. This facilitates hooking the hook assembly 28 to a backing.
