[0003] hand tool

[0004] The invention relates to a hand-held power tool according to the preamble of claim 1.

[0005] State of the art

[0006] Hand-held power tools with a functional unit accommodated in a housing are known from the state of the art.

[0007] Disclosure of the invention

[0008] The invention is based on the object of improving a hand-held power tool using simple design measures.

[0009] The object is achieved with a hand-held power tool having an operating unit for operating the hand-held power tool, with a machine housing, in particular designed as a housing half-shell, for receiving the operating unit and with a functional unit for providing an operating function of the hand-held power tool.

[0010] It is proposed that the hand-held power tool has a receiving unit arranged on the machine housing for receiving the functional unit and / or a further, in particular optional, functional unit.

[0011] Functional units that can be considered include deflection elements and / or spring elements of various types.

[0012] A handheld and / or hand-guided hand tool and preferably an angle grinder are preferably considered as the hand tool. It goes without saying that other hand tools that appear appropriate to a person skilled in the art are also considered. The hand tool can have a drive unit for directly or indirectly driving an accessory device, in particular a disc-shaped accessory device, preferably a grinding wheel. The drive unit can have a drive shaft, in particular one that is mounted so as to be movable about a drive axis. The hand tool can have a control or regulating unit for controlling or regulating the hand tool, in particular the drive unit. The hand tool can have a tool holder for receiving an accessory device, such as a grinding wheel. The tool holder can be mounted so as to be rotatable about an output axis.The tool holder can be driven by the drive unit, for example, to operate the accessory device. For this purpose, the handheld power tool can have a gear unit, in particular an angular gear unit. The gear unit can transmit a movement of the drive unit to the tool holder. To operate the handheld power tool, an actuating element can be provided which can be actuated, in particular actuated in such a way as to place the handheld power tool, in particular the drive unit, into an operating state. In an actuating state, for example, the drive unit can be placed into an operating state, in particular to drive the accessory device.

[0013] Operating unit for operating the hand-held power tool An operating unit can be designed in particular as an actuating unit and / or an adjusting unit.

[0014] The actuating unit can be provided for switching the handheld power tool or the drive unit of the handheld power tool on / off. The actuating unit can have an actuating element. The actuating element can be designed as an actuating pawl. The actuating element can be arranged on the machine housing, in particular a handle area of ​​the machine housing. The actuating element can extend along a longitudinal axis of the handheld power tool, in particular the machine housing. The actuating element can extend relative to a handle area of ​​the machine housing along the longitudinal axis by up to 100%, in particular by up to 90%, preferably by up to 80%, preferably by up to 70%, particularly preferably by up to 60%, and / or by at least 20%, preferably by at least 30%, preferably by at least 40%, particularly preferably by at least 50%, further preferably at least 60%.

[0015] The actuating unit can be configured to adjust the handheld power tool. The actuating unit can lock, release, and / or hold an actuation of the handheld power tool, in particular a drive unit of the handheld power tool, or a movement of the actuating element. The actuating unit can form a locking mechanism. The actuating unit can form a latching mechanism. An adjustment of the actuating unit for actuating the handheld power tool or the drive unit can be provided. The actuating unit can form a switching lock.

[0016] The actuating unit may comprise an actuating element.

[0017] The machine housing can be provided to accommodate the actuating unit. The machine housing can have a housing half-shell. The machine housing can essentially be formed in a half-shell design. The machine housing can enclose the drive unit, the control or regulating unit, the gear unit, and / or at least partially the tool holder.

[0018] The receiving unit can have a receptacle provided for receiving a functional unit, in particular a functional element, and another functional unit, in particular a further functional element. The receiving unit can form a receptacle according to a shape, a configuration, an arrangement, and / or a quantity for receiving the functional units.

[0019] The receiving unit and the machine housing can be formed as a single piece.

[0020] Functional unit for providing an operating function

[0021] An operating function is understood to mean, in particular, a function that is required to actuate and / or operate the handheld power tool, in particular the operating unit. For example, the operating function can enable the release, operation, locking, and / or resetting of the operating unit.

[0022] Alternative or optional functional units

[0023] "Different types" are understood to mean functional units that are replaceable, supplementable, and / or interchangeable with one another. In particular, the functional units should have essentially the same, similar, and / or different functionalities and / or functional means. For example, a functional unit can, in particular by means of a spring element, apply a restoring force to the operating unit, in particular an actuating unit, to return the operating unit from an actuated state to a released state.

[0024] For example, a further functional unit, in particular by means of a spring element, can apply a holding force or a locking force to the operating unit, holding the operating unit in an actuated state and / or in a released state. Accordingly, it is conceivable to provide a handheld power tool with a receiving unit for accommodating both functional units, in order to be able to provide either just one of the two or both functional units.

[0025] Both functional units can be implemented either in a single handheld power tool or in different ones. For example, both functional units can be accommodated by the holding unit. The functional unit and the additional functional unit can be provided individually or separately in the holding unit.

[0026] By means of the present invention, a hand-held power tool can be provided with a machine housing which is universally applicable by enabling the accommodation of different or optional functional units. In particular with regard to the different requirements and wishes of the operators of the hand-held power tools, different functional units can be provided in the hand-held power tool. Since each functional unit requires an arrangement of the functional unit on the machine housing required to fulfill its function, it is provided to equip the machine housing with corresponding receptacles in order to be able to arrange a plurality of functional units on the machine housing. In other words, the machine housing can have different receptacle units in a "redundant manner", which can be equipped with a functional unit as required.Accordingly, a receptacle can be provided in the machine housing even if the machine housing is not equipped with a first type of functional unit, but with a second type of functional unit. This allows a machine housing to be standardized, thus saving resources and costs.

[0027] This means that there is no need to redesign a machine housing if functional units change.

[0028] The subclaims specify further expedient developments of the hand-held power tool according to the invention.

[0029] The functional unit can be designed as a spring element. The further functional unit can be designed as a further spring element. The functional unit, in particular the spring element, can have a different design than the further functional unit, in particular the further spring element. For example, the functional unit can be designed as a spiral spring element. The functional unit can be coupled to an operating unit, in particular an actuating unit and / or an adjusting unit. The functional unit can be arranged and / or clamped between the receiving unit or the machine housing and the adjusting unit. The functional unit can be arranged on the adjusting unit and / or coupled to it and / or clamped thereto. The functional unit can be movably mounted in the machine housing.The functional unit can be arranged in a recess of the actuating unit in one, in particular in every operating state.

[0030] For example, the further functional unit can be designed as a leaf spring element. The further functional unit can be coupled to an operating unit, in particular to an actuating unit and / or to an adjusting unit. The further functional unit can be arranged and / or clamped between the receiving unit or the machine housing and the adjusting unit. The further functional unit can be arranged on the adjusting unit and / or coupled and / or clamped thereto. The further functional unit can be movably mounted in the machine housing. In an operating state, the further functional unit can be arranged in a recess (notch) of the adjusting unit.

[0031] The actuating unit can be provided for locking the actuating unit in an actuating state and / or a release state of the actuating unit.

[0032] This makes it particularly easy to achieve sustainable production of a machine housing, which also allows for faster process times.

[0033] It may be expedient for the receiving unit to have a receiving area for receiving the functional unit. It may also be expedient for the receiving unit to have a further receiving area for receiving a further functional unit. Furthermore, it may be expedient for the receiving area to be spaced apart from the further receiving area. This allows for a particularly simple and compact receiving unit to be provided.

[0034] The receiving area can be provided for receiving a spring element, in particular a spiral spring element. The further receiving area can be provided for receiving a further spring element, in particular a leaf spring element.

[0035] Furthermore, it may be expedient for the receiving area to be designed as a receiving recess and the further receiving area as a further receiving recess. The receiving unit can have a side wall. The receiving recess can be delimited by a side wall. The side wall can be arranged on the machine housing. The side wall can be surrounded by the machine housing. The side wall can be enclosed internally by the machine housing. The side wall can extend in the direction of a longitudinal axis of the machine housing, in particular of the handle housing. The side wall can extend substantially perpendicular to the machine housing. The side wall can extend transversely, in particular perpendicularly, to the machine housing, in particular an inner surface of the machine housing. The side wall can delimit the receiving recess.The receiving area can be provided for a connection, in particular a form-fitting connection, to the spring element. The receiving area can be provided for positioning the spring element on the machine housing.

[0036] Furthermore, it may be expedient for the machine housing to have an adjusting recess for receiving an adjusting element. The receiving area can be arranged on one side of the adjusting recess and the further receiving area on a further side of the adjusting recess facing away from the side. The adjusting recess can be arranged between the receiving area and the further receiving area. The adjusting recess can separate the receiving area from the further receiving area. The adjusting recess can extend through the machine housing. The adjusting recess can be designed as a material opening through the entire material thickness of the machine housing. The receiving area and / or the further receiving area can adjoin the adjusting recess or merge into it. The receiving area and the further receiving area can form a common receiving area with the recess.The adjusting recess can be provided to guide the adjusting element.

[0037] Furthermore, it may be expedient for the spring element, in an operating state, to overlap the adjusting recess and the adjusting element, in particular in a direction transverse to a movement axis of the adjusting element. Furthermore, it may be expedient for the further spring element, in an operating state, to overlap the adjusting recess and the adjusting element, in particular in a direction transverse to a movement axis of the adjusting element. In an operating state, the spring element can be supported on the machine housing on the one hand and on the adjusting element on the other. The spring element can be arranged in the adjusting recess in a gap between the adjusting element and the machine housing and / or protrude beyond the latter. This makes it possible to provide a particularly compact handheld power tool.

[0038] Furthermore, it may be expedient for the additional spring element to be designed to act on the spring element. The additional spring element can limit the movement of the spring element. As a result, the actuating element can be held in an actuated state by means of the additional spring element, for example.

[0039] Furthermore, it may be expedient for the spring element to be arranged, in particular clamped, in a holding recess of the actuating element.

[0040] Furthermore, it may be expedient for the spring element to be held, in particular in a direction transverse to a movement axis of the actuating element, by the holding recess of the actuating element and the receiving recess of the machine housing. Furthermore, it may be expedient for the functional units to be designed as deflection elements, in particular of different types. A deflection element can be provided for actuating a switch unit. The deflection element can transmit a movement, in particular a rotational movement, from an actuating unit to a switch unit. The deflection element can be provided for transmitting a movement from the actuating unit to the switch unit. The deflection element can be arranged at least partially, in particular operatively, between the actuating unit and the switch unit.

[0041] The functional unit can be designed as a deflecting element. The further functional unit can be designed as a further deflecting element. The deflecting element can have a different configuration than the further deflecting element. The deflecting element can be interchangeable with the further deflecting element by the deflecting element and the further deflecting element being arranged on the same receiving unit or storage unit. In particular, the deflecting elements are designed such that the deflecting elements can be arranged on the same receiving unit or storage unit.

[0042] The deflection elements can be coupled to the actuating unit. The deflection elements can be arranged and / or clamped between the actuating unit and the switch unit. The deflection element can be arranged on the actuating unit and / or coupled and / or clamped thereto. The deflection element can be movably mounted in the machine housing, in particular around the receiving unit. The deflection element can be arranged on the machine housing in one, in particular in every, operating state.

[0043] The switch unit can be designed as an on / off switch element. The switch unit can be designed as a potentiometer switch element.

[0044] It may be expedient for the receiving unit to have a receiving region for receiving a functional unit. It may further be expedient for the receiving region to have a receiving element designed as a receiving elevation for receiving the, in particular each, deflection element. The receiving elevation can be substantially cylindrical, in particular bolt-shaped. The receiving unit can be surrounded by the deflection element, in particular completely, preferably in a plane by 360°. The receiving element can be form-fittingly connected to the switch unit. The receiving element can position the switch unit on the machine housing. The receiving element can protrude transversely, in particular perpendicularly, from an inner region of the machine housing. The receiving elevation can have a first end which is arranged on the machine housing. The first end can form a fixed end.The receiving protrusion can have a second end arranged on the machine housing. The second end can form a free end. The receiving protrusion can be designed to be pluggable through the functional units or the deflection elements. For this purpose, the functional units or the deflection elements can each have a plug-in recess.

[0045] The deflection elements can transmit a movement of the actuating unit to the switch unit. The deflection elements can be movably mounted, in particular around a deflection axis. The deflection elements can be arranged between the actuating unit and the switch unit. The deflection elements can transmit an actuating movement, in particular by means of an actuating force, of the actuating unit to the switch unit.

[0046] This allows the mounting element to accommodate various deflection elements. The deflection elements can be adapted to the respective switch to be used, ensuring that only the deflection elements are adapted and not the machine housing.

[0047] It may be expedient for the deflection element, in particular each deflection element, to be rotatably mounted relative to the receiving element. The receiving element or bearing element can be designed to accommodate deflection elements of different types.

[0048] Furthermore, it may be expedient for the deflection element, in particular each deflection element, to be arranged between a switch unit and an actuating unit, wherein the deflection element, in particular each deflection element, deflects a movement of the actuating unit to the switch unit. This allows for a particularly compact design.

[0049] Furthermore, it may be expedient for the deflection element, in particular each deflection element, to have a contact element for contacting the actuating unit and another contact element for contacting the switch unit. The contact elements, in particular their contact points, can be arranged at a distance from the receiving element. The contact elements, in particular their contact points, can have a different distance from the receiving elevation.

[0050] Furthermore, it may be expedient for the contact element to be designed as a contact extension. The further contact element may be designed as a further contact extension. Furthermore, it may be expedient for the deflection element, in particular each deflection element, to have an arcuate section that connects the two contact elements. The deflection elements may differ in the arrangement and / or design of the contact elements of the deflection elements.

[0051] The invention further comprises a system comprising a plurality of hand-held power tools, having a deflection element or a further deflection element.
