Description

State of the art

[0001] From US Patent 5,867,910 A, a handheld garden tool is known, comprising a main functional unit with a first control element and a first electrical unit, and a handle unit that can be coupled to the main functional unit and has a second control element and a second electrical unit. The handle unit can be mechanically attached to the main functional unit by means of a coupling unit. Attaching the handle unit and making an electrical connection, in particular by means of an electrical cable, are carried out separately in two different steps. Reference is also made to German patent DE 203 05 628 U1. Disclosure of the invention

[0002] The invention relates to a handheld garden tool with the features of claim 1. Advantageous embodiments are described in the dependent claims. The coupling unit is designed to electrically connect the first electrical unit to the second electrical unit when the handle unit is attached to the main functional unit, in particular directly and / or immediately, and especially without any additional intervention by a user and / or operator. "Designed" is understood to mean, in particular, specially designed and / or equipped. The phrase "designed" means, in particular, that an object is intended for a specific function and / or performs this specific function in at least one application and / or operating state.

[0003] In this context, a "main functional unit" shall be understood to mean in particular a unit, advantageously at least partially electrical and / or electronic, which advantageously comprises at least a large part of the components of the garden device required in particular for its operation and / or its correct functioning, and / or is intended to enable the operation and / or correct functioning of the garden device.Advantageously, the main functional unit can comprise at least one machine housing, at least one drive unit (preferably at least partially, preferably to a large extent, and particularly preferably completely) arranged within the machine housing, such as an internal combustion engine and / or advantageously an electric motor, at least one energy supply unit (advantageously at least operatively connected to the drive unit), such as a fuel cell, a gasoline tank, a battery, and / or advantageously an accumulator, at least one machining tool (particularly operatively connected to the drive unit), and / or at least one main handle (particularly separate from the handle unit). Furthermore, the main functional unit advantageously comprises at least a part of the coupling unit.The term "at least a large part" shall be understood to mean, in particular, at least 55%, advantageously at least 65%, preferably at least 75%, particularly preferably at least 85%, and particularly advantageously at least 95%. Furthermore, a "handle unit" shall be understood to mean a unit, in particular one designed separately and / or independently from the main functional unit and / or the main handle, which in particular comprises at least one handle housing and is intended to be touched and / or held by an operator in at least one operating state and / or at least during a switch-on process. The handle unit particularly preferably has a shape and / or contour that is advantageously closed and at least substantially D-shaped and / or O-shaped. In addition, the handle unit advantageously comprises at least a part of the coupling unit.

[0004] Furthermore, the term "control element" shall be understood to mean, in particular, an element, advantageously designed as an on / off switch and / or enable switch, which is intended to be touched and / or actuated by an operator, especially at least during the switching-on process and / or during operation of the garden tool. Advantageously, the first control element is arranged on and / or at least partially within the machine housing and preferably in the immediate vicinity of the main handle. In addition, the second control element is advantageously arranged on and / or at least partially within the handle housing.The term "close range" shall be understood to mean, in particular, a spatial area formed by points that are each located at a distance of no more than 10 cm, advantageously no more than 7.5 cm, preferably no more than 5 cm, particularly preferably no more than 2.5 cm, and particularly advantageously no more than 1 cm from a reference point and / or a reference component. Furthermore, the term "electrical unit" shall be understood to mean, in particular, an at least partially electrical and / or electronic unit that is designed, in particular, to enable the operation of the garden device, advantageously depending on contact and / or actuation of one of the operating elements, and / or to control at least another electrical unit, advantageously the drive unit and / or the power supply unit, in particular to start, switch on, and / or release it.The electrical unit can be configured at least partially, preferably at least largely, and particularly preferably entirely as any electrical unit that would be considered useful by a person skilled in the art, such as a switching unit, in particular a push-button switch and / or advantageously a microswitch, a control unit, an actuator unit, a pulse generator, and / or a pulse transmitter. In particular, the first electrical unit has at least one operative connection with the first operating element and is advantageously arranged at least partially, preferably at least largely, and particularly preferably entirely, within the machine housing. Furthermore, the second electrical unit has at least one operative connection with the second operating element and is advantageously arranged at least partially, preferably at least largely, and particularly preferably entirely, within the handle housing.Particularly preferably, the second control element and / or the second electrical unit is provided to enable an operation and / or the drive unit, and the first control element and / or the first electrical unit is provided to start an operation and / or the drive unit and / or to switch on.

[0005] Preferably, the coupling unit, particularly for mechanically attaching the handle unit to the main functional unit, includes a fastening unit. The fastening unit can be any type of fastening unit that would be considered suitable by a person skilled in the art, such as at least partially, preferably at least largely, and most preferably entirely as a snap-fit ​​connection, a plug connection, a bayonet connection, and / or preferably as a screw connection. Furthermore, the coupling unit advantageously includes, particularly for electrically connecting the first electrical unit and / or the second electrical unit, an electrical contacting unit, which is advantageously designed to establish an electrical connection between the first electrical unit and the second electrical unit.Advantageously, the coupling unit is designed to provide at least a substantially positive-locking connection between the handle unit and the main functional unit. A contact surface and / or coupling surface of the handle unit and a contact surface and / or coupling surface of the main functional unit are particularly preferably designed to correspond at least substantially to each other. Furthermore, the coupling unit is preferably designed as a Poka-Yoke system, which allows for a simple, quick, and consistently reliable connection between the main functional unit and the handle unit. By appropriately designing the handheld garden tool, efficiency can be improved, particularly in terms of installation space efficiency, component efficiency, assembly efficiency, and / or time efficiency, especially during assembly.Furthermore, a space-saving and advantageously stable connection between the handle unit and the main functional unit can be achieved, which particularly facilitates maintenance, assembly, and / or the replacement of components. In particular, the handheld garden tool is free of additional connecting cables and / or plug connections between the main functional unit and the handle unit.

[0006] The fastening unit and the contacting unit could, for example, be formed integrally. In this case, it is conceivable that electrical contact between the first electrical unit and / or the second electrical unit is made indirectly and / or directly by means of at least one fastening element of the fastening unit, such as a screw, a screw hole, and / or a locking element. Preferably, however, the coupling unit comprises a fastening unit, in particular several screw holes and advantageously several screws, and a separately formed electrical contacting unit. This allows for a particularly secure connection and fastening.

[0007] In a preferred embodiment of the invention, it is proposed that the handle unit comprises an electrical handle contact unit and the main functional unit comprises an electrical main contact unit corresponding to the handle contact unit, both of which are part of the contacting unit. Preferably, the main contact unit comprises at least one main contact element, advantageously female and / or at least partially configured as a socket element, and in particular electrically connected to the first electrical unit. The handle contact unit comprises at least one handle contact element, advantageously male and / or at least partially configured as a plug element, and in particular electrically connected to the second electrical unit, which make electrical contact, particularly in an assembled state. This allows for a particularly simple, quick, and / or cost-effective connection.

[0008] Furthermore, it is proposed that the handle contact unit has at least one handle contact element which at least partially projects beyond and / or protrudes from the handle unit via a handle housing, in particular the aforementioned handle housing, thereby achieving a particularly advantageously simple contact. Alternatively, however, it is also conceivable that at least one handle contact element of the handle contact unit and / or all handle contact elements of the handle contact unit are arranged in a recess, preferably in the handle housing, thereby advantageously protecting a handle contact element in a disassembled state.

[0009] In one embodiment of the invention, it is proposed that the main contact unit comprises at least one main contact element, which is arranged at least largely and advantageously completely within a recess of a machine housing, in particular the aforementioned machine housing of the main functional unit. Advantageously, all main contact elements of the main contact unit are arranged within a recess, preferably of the machine housing. This allows for particularly simple, reliable, and / or precise positioning. Furthermore, a main contact element can be advantageously protected in a disassembled state.

[0010] A particularly stable and / or secure connection can be achieved if the fastening unit is located in close proximity to the contact unit, especially at a maximum distance of 10 cm. This also advantageously reduces the torque acting on the contact unit.

[0011] If the handle unit is free of a power supply unit, especially a battery, the complexity of the connection and / or the weight of the handle unit can be advantageously reduced. Furthermore, component efficiency and / or cost efficiency can be increased.

[0012] In a preferred embodiment of the invention, it is proposed that the coupling unit comprises at least one contact element, advantageously the main contact element of the main contact unit mentioned above, the distal end of which includes an insertion aid for at least one further contact element of the coupling unit, advantageously the handle contact element of the handle unit mentioned above. In this context, an "insertion aid" is understood to mean, in particular, an object designed to facilitate coupling between the contact element and the further contact element during a coupling process and / or during the attachment of the handle unit to the main functional unit, and / or to prevent incorrect coupling between the contact element and the further contact element.Furthermore, a "distal end" is understood to be an end of the contact element facing the other contact element during the coupling process. This allows for a particularly simple and / or functionally correct coupling.

[0013] The handheld garden tool is not limited to the application and embodiment described above. In particular, the handheld garden tool may, to fulfill the functionality described herein, have a different number of individual elements, components, and units than specified herein. drawing

[0016] The Fig. 1 and Fig. Figure 2 shows an exemplary handheld garden tool designed as hedge shears in an unassembled state (see Figure 2). Fig. 1) and in an assembled state (see Fig. 2), in particular in Fig. 2. For the sake of clarity, some components of the garden tool have been removed. The handheld garden tool is designed to be motorized. The handheld garden tool is also cordless. In this case, the handheld garden tool is battery-operated and / or rechargeable battery-operated. In this case, the handheld garden tool is designed for two-handed operation. Alternatively, it is conceivable to design a handheld garden tool as any other handheld garden tool that a specialist would deem useful, such as grass shears and / or loppers. Furthermore, a handheld garden tool could be corded and thus, in particular, mains-powered.

[0017] The handheld garden tool has a main functional unit 10. The main functional unit 10 comprises most of the components required for operating the garden tool. The main functional unit 10 includes a machine housing 48. Furthermore, the main functional unit 10 includes a processing tool 62. The processing tool 62 is designed as a cutting blade. In addition, the main functional unit 10 includes a drive unit (not shown). The drive unit is completely enclosed within the machine housing 48. The drive unit is designed as a motor, in this case, specifically an electric motor. The drive unit has a functional connection with the processing tool 62. The drive unit is designed to operate the processing tool 62 in at least one operating state. For power supply, the main functional unit 10 also includes a power supply unit (not shown).The power supply unit is designed to be interchangeable and / or replaceable. The power supply unit can be coupled to the machine housing 48. In this case, the power supply unit is designed as a rechargeable battery. Alternatively, it is conceivable to design the power supply unit as a battery, a fuel cell, and / or a gasoline tank. The power supply unit has a functional connection with the drive unit. The power supply unit is intended, at least in one operating state, to supply the drive unit with energy. Furthermore, the main functional unit 10 has a main handle 64. The main handle 64 is designed as a rear handle. The main handle 64 is arranged on a side of the garden tool facing away from the processing tool 62. The main handle 64 is intended, at least substantially, for holding the garden tool.

[0018] The main functional unit 10 also includes a first control element 12. The first control element 12 is designed as an actuating element. The first control element 12 is located in the immediate vicinity of the main handle 64. In this case, the first control element 12 is located on the inside of the main handle 64.

The main functional unit 10 also includes a first electrical unit 14. The first electrical unit 14 is located entirely within the machine housing 48. In this case, the first electrical unit 14 is designed as a switching unit. The first electrical unit 14 has an operative connection with the first control element 12.Furthermore, the first electrical unit 14 has an operative connection with the drive unit and / or the power supply unit. The first electrical unit 14 is designed to control the drive unit and / or the power supply unit in at least one operating state.

[0019] The first electrical unit 14 is designed to start the drive unit and / or supply the drive unit with energy, in particular by means of the power supply unit, depending on the actuation of the first control element 12 in at least one operating state. Furthermore, a main functional unit can comprise other units, such as a control unit, an electronics unit, and / or a gearbox unit.

[0020] The handheld garden tool has a handle unit 16. The handle unit 16 is separate from the main functional unit 10. The handle unit 16 is separate from the main handle 64. In this case, the handle unit 16 is free of a power supply unit, in particular a battery and / or accumulator. The handle unit 16 is designed as a front handle. The handle unit 16 is located in close proximity to the working tool 62. The handle unit 16 has a shape and / or contour that is at least substantially D-shaped. The handle unit 16 is also at least substantially ring-shaped. The handle unit 16 is completely closed in the circumferential direction. The handle unit 16 thus corresponds to a closed loop. The handle unit 16 is designed at least substantially for guiding the garden tool. In addition, the handle unit 16 has a handle housing 40.

[0021] The handle unit 16 further comprises at least one second operating element 18. In the present case, the handle unit 16 includes three second operating elements 18, which in particular enables particularly comfortable handling regardless of the grip position. The second operating elements 18 are at least substantially identical to each other. The second operating elements 18 are designed as actuating elements. The second operating elements 18 are arranged on an inner side of the handle housing 40. The second operating elements 18 are each arranged at an angle of approximately 90° to each other. The second operating elements 18 are spring-loaded (see in particular [reference]). Fig. 3) Alternatively, it is also conceivable to mount the second operating elements in any other manner that would appear sensible to a specialist. Furthermore, the second operating elements 18 are each designed as enabling switches and / or safety switches. The second operating elements 18 are intended to be actuated by an operator at least during the initial switch-on process of the garden tool. In the present case, one of the second operating elements 18 can be actuated selectively during a switch-on process. The handle unit 16 also has at least one second electrical unit 20 (see in particular...). Fig. 3) In the present case, the handle unit 16 comprises three second electrical units 20. The second electrical units 20 are electrically connected to each other, in this case, in particular by means of a cable. The second electrical units 20 are completely arranged within the handle housing 40. The second electrical units 20 are designed as switching units, in this case, in particular as microswitches. Each of the second electrical units 20 has an operative connection, advantageously by means of an actuator element, with one of the second operating elements 18. In addition, the second electrical units 20 have an electrical connection with the first electrical unit 14 in the assembled state.The second electrical units 20 are each designed to control the first electrical unit 14, depending on the actuation of the corresponding second control element 18 in at least one operating state, and in particular to activate the drive unit and / or a power supply to the drive unit. Furthermore, a handle unit could comprise additional units, such as an electronic unit and / or an additional power supply unit. It is also conceivable that a handle unit has exactly one second control element and / or exactly one second electrical unit. In addition, a handle unit could have any other number of second control elements and / or second electrical units that would be considered reasonable by a person skilled in the art, such as at least two, at least three, and / or at least four second control elements and / or second electrical units.Furthermore, the number of second control elements could differ from the number of second electrical units.

[0022] Furthermore, the handheld garden tool has a coupling unit 22. The coupling unit 22 is at least partially formed by the main functional unit 10. The coupling unit 22 is also at least partially formed by the handle unit 16. In this case, the coupling unit 22 is designed to form a positive-locking connection between the main functional unit 10 and the handle unit 16. A contact surface of the main functional unit 10 and a contact surface of the handle unit 16 are designed to correspond to each other, which allows for a precise attachment and advantageously eliminates the need for additional covers. The coupling unit 22 is also designed as a Poka-Yoke system, which allows for a simple, quick, and consistently reliable coupling. The coupling unit 22 is designed for the mechanical attachment of the handle unit 16 to the main functional unit 10.The coupling unit 22 includes a fastening unit 24. In this case, the fastening unit 24 is designed at least substantially as a screw connection. The fastening unit 24 includes at least one first screw hole 26. In this case, the fastening unit 24 includes four first screw holes 26. The first screw holes 26 are designed at least substantially identically to each other. The first screw holes 26 are arranged in and / or on the machine housing 48. In this case, the first screw holes 26 are arranged on a lower surface of the machine housing 48. Furthermore, the fastening unit 24 includes at least one second screw hole 28. In this case, the fastening unit 24 includes four second screw holes 28. The second screw holes 28 are designed at least substantially identically to each other. In addition, the second screw holes 28 correspond to the first screw holes 26.The second screw holes 28 are located in and / or on the handle housing 40. In this case, the second screw holes 28 completely penetrate the handle housing 40. The second screw holes 28 are located on the inside of the handle housing 40. Specifically, the second screw holes 28 are located on an inside surface of the handle housing 40 opposite and / or adjacent to the second operating elements 18. Furthermore, the fastening unit 24 has four screws 29. The screws 29 are intended to fasten the handle unit 16 to the main functional unit 10 by means of the first and second screw holes 26, 28. Alternatively, it is conceivable to design a fastening unit as any other fastening unit that would be considered useful by a person skilled in the art, such as a snap-fit ​​connection and / or a plug connection.Furthermore, a fastening unit could have any other number of first and / or second screw holes, such as at least two, at least three, at least four, at least five and / or at least six screw holes.

[0023] Furthermore, the coupling unit 22 is designed to electrically connect the first electrical unit 14 with at least one of the second electrical units 20, and in this case, in particular all of the second electrical units 20, when the handle unit 16 is attached to the main functional unit 10, especially directly and without any additional intervention by the operator. For this purpose, the coupling unit 22 comprises an electrical contacting unit 30. The contacting unit 30 is separate from the mounting unit 24. The contacting unit 30 is located in close proximity to the mounting unit 24. A maximum distance between the contacting unit 30 and the mounting unit 24 is 10 cm. In this case, the distance between the contacting unit 30 and the mounting unit 24 is 3 cm. The contacting unit 30 is also designed in at least two parts.The contacting unit 30 is designed to establish an electrical connection between the first electrical unit 14 and at least one of the second electrical units 20, in this case, in particular, all of the second electrical units 20.

The handle contact unit 32 also has at least one contact element 36, 38, 58, 60. The at least one contact element 36, 38, 58, 60 of the handle contact unit 32 is designed as a handle contact element 36, 38, 58, 60. In the present case, the handle contact unit 32 comprises exactly two handle contact elements 36, 38, 58, 60.The handle contact elements 36, 38, 58, 60 are designed as male contact elements.

The handle contact elements 36, 38, 58, 60 are arranged in a recess of the base element 66. In the present case, the handle contact elements 36, 38, 58, 60 are arranged such that, in a mounted state, the handle contact elements 36, 38, 58, 60 protrude at least partially beyond the handle housing 40 (see Figure 1).in particular . Fig. 6 and Fig. 7) Furthermore, the handle contact elements 36, 38, 58, 60 have an electrical connection with at least one of the second electrical units 20, in the present case in particular all of the second electrical units 20.

[0025] The Fig. 1 and Fig. Figure 4 shows the main contact unit 34. The main contact unit 34 is part of the main functional unit 10. The main contact unit 34 is designed separately from the handle contact unit 32. The main contact unit 34 is separable from the handle contact unit 32. The main contact unit 34 is designed to correspond to the handle contact unit 32. The main contact unit 34 is arranged on the machine housing 48. The main contact unit 34 comprises a further base element 68. The further base element 68 has at least one receiving recess 70. In this case, the further base element 68 comprises two receiving recesses 70. The further base element 68 has a shape and / or contour that is at least substantially rectangular. The further base element 68 is made of plastic.The further basic element 68 is attached to the machine housing 48, in particular in a recess 46 of the machine housing 48, especially by means of a force-fit, a form-fit, and / or a material-fit connection. The main contact unit 34 also has at least one contact element 42, 44, 50, 52. The at least one contact element 42, 44, 50, 52 of the main contact unit 34 is designed as a main contact element 42, 44, 50, 52. In the present case, the main contact unit 34 comprises exactly two main contact elements 42, 44, 50, 52. The main contact elements 42, 44, 50, 52 are designed as female contact elements. The main contact elements 42, 44, 50, 52 correspond to the grip contact elements 36, 38, 58, 60. The main contact elements 42, 44, 50, 52 are at least substantially V-shaped when viewed from the side. The main contact elements 42, 44, 50, 52 are made of an electrically conductive material.In this case, the main contact elements 42, 44, 50, 52 are made of steel. The main contact elements 42, 44, 50, 52 are arranged on the further base element 68. In this case, the main contact elements 42, 44, 50, 52 are overmolded with the further base element 68. The main contact elements 42, 44, 50, 52 are each completely arranged in one of the receiving recesses 70 of the further base element 68. A distal end of the main contact elements 42, 44, 50, 52 includes an insertion aid 54, 56 for the handle contact elements 36, 38, 58, 60, which in particular simplifies the connection of the main contact elements 42, 44, 50, 52 and the handle contact elements 36, 38, 58, 60. In this case, the insertion aid 54, 56 consists of an outwardly bent and / or a part of the main contact elements 42, 44, 50, 52 bent away from the grip contact elements 36, 38, 58, 60.Furthermore, the main contact elements 42, 44, 50, 52 are arranged such that, in an assembled state, the main contact elements 42, 44, 50, 52 are arranged to a large extent in the recess 46 of the machine housing 48 (see in particular also . Fig. 6 and Fig. 7) Furthermore, the main contact elements 42, 44, 50, 52 have an electrical connection with the first electrical unit 14. Alternatively, it is conceivable that a handle contact unit and / or a main contact unit has a different number of contact elements, such as exactly one and / or at least three contact elements. In addition, a contact element could consist at least partially, at least largely, or entirely of a material other than steel, such as gold, aluminum, brass, and / or copper. It is also conceivable to form a handle housing and a base element and / or a main functional housing and another base element in one piece.

[0026] The Fig. 6 and Fig. Figure 7 shows the main contact unit 34 and the handle contact unit 32 in the unassembled state (see in particular Fig. 6) and in the assembled state (see in particular Fig.7) in a lateral sectional view. In the assembled state, the handle contact elements 36, 38, 58, 60 engage with the main contact elements 42, 44, 50, 52. This results in an electrical connection between the handle contact elements 36, 38, 58, 60 and the main contact elements 42, 44, 50, 52 immediately upon attachment of the handle unit 16 to the main functional unit 10, and thus in particular also between the first electrical unit 14 and at least one of the second electrical units 20, in this case in particular all of the second electrical units 20, thereby enabling the operation of the garden tool.Such a design of a handheld garden tool makes it possible to achieve a space-saving, advantageously stable and quick connection between the main functional unit and the handle unit, thereby eliminating the need for additional connecting cables and / or plug connections between the main functional unit and the handle unit.
