The present invention relates to a hand-held and hand-guided tool device, comprising a housing with at least one handle device for a user, a drive device arranged in the housing, a battery for providing electrical energy, a battery receptacle for receiving the battery in an inserted state, which in a removed state from the Battery holder is removed, at least one tool unit which can be driven by the drive device and which comprises at least one tool, in particular for the separating processing of objects and a tool holder arranged on the housing, the tool unit in a working position being partially arranged in the tool holder and coupled to the drive device and is removed in a released position of the tool holder.

Due to the design of the tool unit, such a tool device can be, for example, an electric hedge trimmer, in which the tool unit has at least one reciprocating knife, preferably two counter-rotating knives, for cutting thin branches or the like. The electrical energy for the drive device is provided by the battery which is in the inserted state. The tool device can comprise a drive element which drives the at least one tool, in particular such that it can move back and forth. If the battery is removed from the battery receptacle and is in the removal state, the drive device cannot be supplied with electrical energy and the tool device cannot be operated, so that the at least one tool cannot move.

The tool unit can be removed from the tool holder, for example, for maintenance, in particular for re-sharpening. As an alternative or in addition, there is, for example, the possibility that different tool units are provided, as a result of which various activities can be carried out with the tool device, which will be discussed below.

An electric motor-operated grass shear with battery operation is in the EP 1 479 284 A1 described.

Further embodiments of handheld tool devices are disclosed in US Pat EP 1 424 002 A1 , the JP 2008-173047 A and in the JP 2014-27911 A described.

The object of the present invention is to provide a tool device of the type mentioned at the beginning, which has a higher level of operational reliability.

This object is achieved in a generic tool device according to the invention in that the tool device comprises a blocking element which moves from a blocking position in which the tool unit is secured against removal in the tool holder, to a release position in which the tool unit can be removed from the tool holder, and vice versa can be transferred, wherein the blocking element can only be transferred into the release position for releasing the tool holder after the battery has been removed from the battery holder, in order to remove the tool unit.

A blocking element is provided in the tool device according to the invention. The blocking element can assume a blocking position. In the blocking position, the tool unit arranged in the tool holder is secured and cannot be removed from the tool holder. In order to remove the tool unit, the blocking element must first be moved into the release position. Provision is made according to the present invention that the blocking element can only assume the release position when the battery has been removed from the battery receptacle. Removing the battery ensures that the drive device is not acted upon electrically, so that the at least one tool cannot be started. This protects the user from unintentional movement of the tool when the tool unit is removed from the tool holder. This reduces the risk of injury to the user. As a result, the operational reliability of the tool device is increased in relation to a generic tool device.

It goes without saying that the battery can preferably be designed to be rechargeable.

In a preferred embodiment of the tool device according to the invention, it is provided that the blocking element and the battery comprise or form corresponding contact elements that rest against one another when the battery is inserted and when the blocking element is in the blocking position, and that the blocking element is in the inserted state in the battery receptacle as long as the battery is in the inserted state , cannot be transferred from the blocking position to the release position. In particular, it is provided here that the blocking element is not even movable when the battery assumes the inserted state, because the contact elements of the blocking element and the battery interact in such a way that the blocking element cannot or essentially cannot be moved. Only in In the state of removal of the battery, the blocking element can be transferred from the blocking position to the release position.

In another advantageous embodiment of the tool device according to the invention, it is provided that the blocking element and the battery comprise or form corresponding contact elements which come to rest against each other when the blocking element is transferred from the blocking position in the direction of the release position and prevent further movement of the blocking element when the battery assumes the inserted state, the tool holder being partially released, but the tool unit cannot be removed from it. In such an embodiment there is the possibility of moving the blocking element in the direction of the release position. The tool holder is partially released. However, the tool unit cannot yet be removed from the tool holder and is further secured against removal by the blocking element. The corresponding contact elements of the blocking element and the battery work together and can rest against one another after the blocking element has been moved as long as the battery is still in the inserted state. Only after the battery has been removed can the blocking element be moved further into the release position in order to remove the tool unit.

In the last-mentioned advantageous embodiment, for example, there may be the possibility of accessing the tool unit arranged in the tool holder. This is conceivable, for example, for maintenance purposes, for example for lubricating moving parts of the tool unit and / or the drive device.

It is advantageous if electrical contact elements for interacting with the battery are arranged on the battery receptacle and if the blocking element covers the contact elements in the release position. As a result, the contact elements can preferably be protected from dirt and / or moisture.

It can be provided that the blocking element completely covers the battery receptacle in the release position.

It is favorable if the at least one tool unit is free from housing parts of the housing. For example, this can result in advantages in the handling of the at least one tool unit due to the smaller dimensions. The production costs for the tool unit can advantageously be reduced. This can be particularly advantageous if a plurality of tool units is provided in the tool device and a respective housing part can be saved as a result.

It is advantageous if the blocking element comprises or forms a cover element which at least partially and preferably completely or essentially completely closes the tool holder in the blocking position. In this case, it is preferably provided in particular that the cover element covers a section of the tool unit arranged in the tool holder and blocks this section of the tool unit from being removed from the tool holder.

It is favorable if the tool holder can be closed in a sealing manner by means of the cover element in order to make it more difficult or even to prevent the penetration of dirt and / or moisture into the tool holder.

If the cover element assumes the blocking position, it can preferably be secured in the blocking position by means of at least one locking element in order to prevent unintentional movement from the blocking position into the release position. The locking of the blocking element, in particular the cover element, will be discussed below.

For simple handling of the tool device, it is advantageous if the blocking element is designed to be displaceable relative to the housing for transferring from the blocking position to the release position and vice versa.

The cover element is expediently displaceable in a plane defined by it, for example in the case of a planar configuration.

It proves to be advantageous if the housing comprises or forms a guide device for the blocking element, in particular the cover element, for guiding the movement of the blocking element. The guide device makes it easier for the user to transfer the blocking element from the blocking position to the release position and preferably vice versa.

It is advantageous if the battery of the battery receptacle can be removed in a removal direction, and if the blocking element in the removal direction from the blocking position into the Release position is transferable. This makes it easier for the user to handle the tool device. The user can first transfer the battery in the removal direction into the removal state in an easy-to-use manner. The blocking element can then be moved into the release position in the removal direction. Conversely, the user can preferably move the blocking element into the blocking position counter to the removal direction and insert the battery into the battery receptacle counter to the removal direction.

The blocking element is advantageously held captive on the housing. The blocking element is preferably secured on the housing regardless of its position. For this purpose, it can, for example, be in engagement with a guide formed by the housing regardless of its position. A stop element can be provided on the housing, against which the blocking element strikes, for example in the release position, in order to prevent further movement relative to the housing.

In a preferred embodiment, provision can be made for the housing to have half-shells which, when joined together, form a recess between them in which the blocking element is received, and preferably a stop element for the blocking element occupying the release position. The blocking element engages, for example, between two sections of the housing separated at a distance from one another and via the recess, each section being formed by one of the half-shells. Edges of the recess preferably form the guide device for the blocking element. The stop element preferably limits the range of motion, in particular the displacement paths of the blocking element.

The blocking element is preferably arranged on a side of the housing facing away from the handle device, in particular on an underside. This reduces the probability that the user, when accessing the blocking element, actuates an actuating element arranged on the handle device, with which the drive device could be started.

To drive the at least one tool unit, the drive device preferably comprises a drive element. The drive element is, for example, coupled to a drive motor or part of the drive motor. In a preferred embodiment, the drive element can in particular be designed as a drive shaft or drive pin which can be driven to rotate about an axis. For example, the drive element protrudes into the tool holder and is there in operative connection with the tool unit.

It is favorable if the at least one tool unit comprises at least one eccentric element which is coupled to the at least one tool and which is coupled directly or indirectly to a rotating drive element of the drive device that is arranged in the tool holder. The at least one eccentric element can be in operative connection with the drive element and thereby preferably rotate about an axis that differs from the axis of the drive element. As a result, the at least one tool can perform a reciprocating movement.

It is advantageous if the tool device comprises a first locking element which is arranged on the blocking element and interacts with a corresponding second locking element arranged on the tool holder in order to secure the blocking element in the blocking position on the housing. The locking elements can be used to ensure that the blocking element is not inadvertently transferred from the blocking position to the release position.

The second locking element is advantageously held in a stationary manner on the tool holder. This facilitates the handling of the tool device for locking the blocking element.

The locking elements can be in a non-positive and / or positive engagement in an engaged state. For example, a form fit, a clamp connection, a latching connection or the like is conceivable.

It can be provided that the tool unit is acted upon by means of the first locking element with a force pointing in the direction of the tool holder, so that the tool unit can be held in a secured position in the tool holder by means of the locking element.

It is advantageous if the first locking element is fixed on the blocking element and is preferably held captive thereon.

For simplified handling of the tool device, it is advantageous if the first locking element can be actuated manually and without tools is for locking with the second locking element and for unlocking from the second locking element.

In a preferred embodiment of the tool device according to the invention, the first locking element comprises a rotary knob or is designed as such.

It can be provided, for example, that a recess is formed on the first locking element, into which the second locking element can be inserted, with at least one engaging strip and groove being arranged on the recess and on the second locking element. The second locking element is expediently introduced into the recess when the blocking element is transferred into the blocking position. At least one strip is arranged on the recess, for example, which can engage in a groove on the second locking element, or vice versa. If a rotary knob is provided, as explained above, the recess can, for example, be configured in sections in an arcuate manner, so that the second locking element can be secured on the first locking element by turning the rotary knob.

The tool unit is expediently in engagement with the second locking element. In this way, the position of the tool unit in the tool holder can be secured.

A through opening formed on the tool unit is expediently provided, through which the second locking element engages.

It is advantageous if the tool device comprises an alignment element which is arranged at a distance from the second locking element, is held in a stationary manner on the tool holder and is in engagement with the tool unit. This makes it possible to secure the position of the tool unit in the tool holder.

The tool device according to the invention according to the 1 until 4th is assigned the reference numeral 10 as a whole. It is designed as an electric hedge trimmer and includes a tool unit 12th with two counter-rotating tools as explained below 14th . With the tools 14th are cutting tools, also known as knives 16 for separating small branches or the like. The tool unit 12th is in the 1 until 4th only partially shown. the 6th and 7th show the tool unit 12th Completely.

The tool device 10 further comprises a housing 18th . The case 18th has two housing half-shells joined together 20th , 22nd on. The case 18th has a top 24 and a bottom 26th on and also a back 28 and a front 30th .

Information on position and orientation are present as referring to the intended use of the tool device 10 related to understand. The user grasps the tool device 10 when used as intended, especially from the rear, so that the back 28 facing the user. The tool unit 12th stands from the front 30th away. The user is the top 24 facing, and the bottom 26th points away from the user.

A handle device 32 is provided, formed by a recess on the housing 18th . On the handle device 32 is an actuator 34 to activate the tool device 10 arranged. In addition, there is a further, bow-shaped handle device 36 for guiding the tool device 10 intended.

Between the housing half-shells 20th , 22nd is a receiving space of the housing 18th educated. A drive device is located in the receiving space 38 to drive the tools 14th recorded. The drive device 38 includes in particular an electric motor 40 ( 8th ).

The electric motor 40 drives a drive element 42 on, which in the present case is designed as a peg-shaped polygon with a non-circular cross-section. The drive element 42 defines an axis 44 .

To provide electrical energy for the drive device 38 has the tool device 10 a presently rechargeable electric battery 46 on. For the battery 46 is at the bottom 26th , adjacent to the back 28 , a battery holder 48 on the housing 18th intended.

The battery 46 can adopt a removal state in which they are in the battery receptacle 48 is arranged and is fixed therein, for example, latching. The battery 46 can be transferred to a removal state in which it is the battery receptacle 48 is removed. In particular, the battery 46 in a removal direction 50 to the rear out of the battery holder 48 pulled.

Battery electrical contact elements 46 can in the inserted state with electrical contact elements 52 cooperate on the battery holder 48 are arranged. Here are the contact elements 52 at the back 28 facing away from the battery holder 48 arranged ( 2 ).

On the bottom 26th is on the housing 18th a tool holder 54 arranged. In the tool holder 54 can the tool unit 12th in a working position with a section 56 be partially included. The tool unit 12th can from the housing 18th can be solved by the section 56 the tool holder 54 is removed. A Separating the tool unit 12th from the housing 18th can for example be advantageous to the tool unit 12th to maintain, especially the knives 16 to sharpen.

Alternatively or in addition, it can be provided that in the case of the tool device 10 Different types of tool units are used, which differ with regard to the at least one tool 14th differ from each other.

The tool holder 54 closes when viewed from the rear 28 to the front 30th to the battery holder 48 and extends essentially to the front 30th .

For training the tool holder 54 is between the housing half-shells 20th , 22nd a housing part 58 inserted ( 4th and 8th ). On the housing part 58 is for example the electric motor 40 held.

The housing part 58 limits the tool holder 54 in the height direction of the tool device 10 up. As the tool device 10 like in the 1 until 4th shown is usually turned upside down for the purpose of maintenance, the housing part 58 as the "bottom" of the tool holder 54 be viewed as training.

The tool holder is on the side 54 of edges 60 and 62 limited by the housing half-shells 20th or. 22nd are formed. The edges 60 , 62 stand over the housing part 58 addition, so that between them a recess 64 between the half-shells 20th , 22nd is formed. On the front side 30th is an implementation 66 for the tool unit 12th available.

For closing the tool holder 54 is a cover element 68 provided that a blocking element 69 of the present invention. The cover element 68 can in the broader sense as a housing part 70 of the housing 18th be considered.

The cover element 68 is at the bottom 26th arranged and designed in the present case plate-shaped. On the bottom 26th is the cover element 68 planar, which makes it difficult for dirt to settle and makes cleaning easier.

The cover element 68 is the recess 64 used, with edges of the cover element 68 with the edges 60 , 62 couple.

At the edges 60 , 62 is the cover element 68 movable relative to the housing 18th held. Thereby form the edges 60 , 62 a guide device 72 and one guide element each.

The cover element 68 can be relative to the housing 18th in the longitudinal direction of the tool device 10 be moved. It is possible to use the cover element 68 towards the rear 28 to move. This corresponds to a movement in the removal direction 50 . Conversely, the cover element 68 towards the front 30th moved back against the direction of removal 50 .

The cover element 68 is like that between the half-shells 20th , 22nd inserted that it on the case 18th is held captive. Thereby the half-shells form 20th , 22nd a stop element 74 at the edges 60 , 62 so that the cover element 68 backwards only to the end of the tool holder 54 can be moved, but not out of engagement with the margins 60 , 62 got.

The displacement path of the cover element 68 forward is through a on the tool holder 54 arranged locking element 134 limited, which will be discussed below.

The drive element 42 reaches through the housing part 58 and thereby protrudes into the tool holder 54 .

As in particular from the 8th and 9 can be seen, the knives are 16 flat on top of each other. On a respective knife 16 is at the section 56 that goes into the tool holder 54 can be used, (not shown) formed an elongated hole running in its longitudinal extension.

At the section 56 point the knife 16 a coupling link 76 on, in which a through opening 78 is formed. The present is in 9 only one coupling link 76 with a through opening 78 shown. The passage opening 78 is out of round and in the present case in particular approximately elliptical.

In the through opening 78 is a drive link 80 used. The drive link 80 is in the present case a disc with a circular shape and forms an eccentric element. Two through openings are eccentric 82 in the drive link 80 educated. On the side next to a through opening 82 are two more through openings 84 in the drive link 80 educated.

The tool unit 12th includes one of the knives 16 covering holding member 86 . In the holding member 86 are two through openings 88 formed, which are arranged at a distance from one another and above the elongated holes in the knives 16 are positioned.

In addition, is in the holding member 86 a through opening 90 educated. In the through opening 90 is a link 92 added, in this case a disc in the shape of a circle. Central on the connecting link 92 is a recording 94 educated. The recording 94 is designed in cross-section so that it connects to the drive element 42 cooperates. That about the axis 44 rotating drive element 42 can thereby the connecting link 92 also around the axis 44 drive rotating.

On the side next to the recording 94 are through openings 96 in the link 92 educated. The through openings 96 can with the through holes 84 both drive links 80 cursing.

Fixing members 98 in the form of pins reach through the through openings 96 of the connecting link 92 and 84 the drive links 80 and are fixed by a force fit or form fit so that the drive links 80 and the connecting link 92 are connected to each other.

The drive element 42 reaches through from the drive links 80 a different one of the through openings 82 so that the drive links 80 are superimposed in a non-aligned manner. Instead, the drive links are 80 each eccentric to the drive element 42 positioned but in opposite directions.

When the drive element 42 rotates, the drive links rotate 80 thus each eccentric around the axis 44 , and the knives 16 are moved in opposite directions.

The tool unit 12th further comprises a reinforcement element 100 in the form of a profile that is on the housing part 58 rests and is positively engaged with this. This is the tool unit 12th Reliable in the tool holder both in the longitudinal direction and in the transverse direction 54 held.

On the housing part 58 is stationary an alignment element 102 in the form of a peg 104 arranged. The cone 104 reaches through the oblong holes of the knife 16 and one of the through openings 88 and is used for additional fixation of the tool unit 12th in the tool holder 54 . Another stationary alignment element 106 is at a distance from the alignment element 102 provided and also as a pin 108 designed. The cone 108 also reaches through the oblong holes of the knife 16 and the other of the through holes 88 .

Like in particular from 3 is recognizable is the section 56 in the working position of the tool unit 12th in the tool holder 54 arranged. The tool unit 12th stands with the drive element 42 and the two pegs 104 and 108 engaged. The knife 16 and the reinforcement element 100 crack down on the implementation 66 and protrude from the housing 18th out.

The cover element 68 can assume a blocking position. The blocking position of the cover element 68 is in the 1 and 2 shown. In the blocking position, the cover element covers 68 the tool holder 54 and the section contained therein 56 the tool unit 12th . Takes the cover element 68 the blocking position, the tool unit 12th not from the tool holder 54 can be taken from what the designation blocking element 69 justified.

A removal of the tool unit 12th from the tool holder 54 is only possible after the cover element 68 has been moved from the blocking position to a release position. Takes the cover element 68 the release position, it is so far relative to the housing 18th moved that a removal opening of the tool holder 54 is exposed to the removal of the tool unit 12th to enable ( 3 and 4th ). In the release position of the cover element 68 can the tool unit 12th or another type of tool unit in the empty tool holder 54 can be used.

In the present invention, there is a particular advantage that the cover element 68 can only be moved to the release position when the battery 46 the battery holder 48 has been removed.

Is the battery 46 in the battery holder 48 In contrast, when used, this is not possible. The battery 46 and the cover element 68 include corresponding investment elements 110 or. 112 . The investment element 110 is on the cover element 68 facing end of the battery 46 arranged. The investment element 112 is at that of the battery 46 facing end face of the cover element 68 arranged.

In the blocking position of the cover element 68 are the plant elements 110 , 112 to each other when the battery 46 in the battery holder 48 is inserted ( 1 ). This prevents the cover element 68 to move. For this purpose, first is the battery 46 the battery holder 48 refer to. This is the battery intake 48 exposed ( 2 ). Then the cover element 68 from the the section 56 concealing and the tool holder 54 locking position, in the present example, via the battery receptacle 48 moved and into the Release position are transferred so that the tool unit 12th is removable ( 3 and 4th ).

It is advantageous for handling that the battery can be removed 46 and moving the cover element 68 in both cases in the direction of removal 50 he follows.

In the release position there is the advantage that the cover element 68 the battery holder 48 at least partially covered so far that the contact elements 52 are covered. This will make the contact elements 52 protected from dirt and moisture. At the tool device 10 becomes the battery intake 48 even essentially completely covered, as in the 3 and 4th can be seen.

The ones in the 5 until 7th shown and with the reference number 120 The occupied embodiment of the tool device according to the invention differs from the tool device, for example, in the last-mentioned point 10 . As from the 5 until 7th can be seen is the housing 18th at the tool device 120 compared to the tool device 10 designed longer. The handle device 32 upstream is a housing section 122 arranged. Sections of the housing located in front of and behind in the longitudinal direction 18th are identical to the housing 18th the tool device 10 designed.

At the tool device 120 covers the cover element 68 the battery holder in the release position 48 so only partially.

Another difference between the tool devices 10 and 120 is that the cover element 68 at the tool device 120 starting from the blocking position can be moved in the direction of the release position. However, the release position can only be taken when the battery 46 as with the tool device 10 was taken.

5 represents this. The cover element 68 starting from the blocking position shifted until the contact elements 110 , 112 to the system and the battery 46 the further displacement of the cover element 68 prevented.

In this case the tool holder is 54 partially released, the tool unit 12th however, this cannot be removed.
