Description

Technical Field

[0001] The invention relates to a handheld power tool according to the preamble of claim 1 . Background Art

[0003] The object of the present invention is to improve a hand-held power tool by means of simple structural measures.

[0004] This object is achieved by means of a handheld power tool having an operating unit for operating the handheld power tool, having a machine housing, in particular designed as a housing half-shell, for accommodating the operating unit, and a functional unit for providing operating functions of the handheld power tool.

[0006] Suitable functional units include, in particular, different types of deflection elements and / or spring elements.

[0007] Handheld machine tools

[0008] Preferably, a handheld and / or hand-guided handheld power tool and preferably an angle grinder are considered as handheld power tools. Of course, other handheld power tools that seem meaningful to a person skilled in the art may also be considered. The handheld power tool may have a drive unit for indirectly or directly driving an accessory device, in particular a disc-shaped accessory device, preferably a grinding disk. The drive unit may have a drive shaft, in particular a drive shaft movably supported around a drive axis. The handheld power tool may have a control or regulating unit for controlling or regulating the handheld power tool, in particular the drive unit. The handheld power tool may have a tool receiving portion for receiving an accessory device, such as a grinding disk. The tool receiving portion may be rotatably supported around an output axis. The tool receiving portion may be driven by means of a drive unit, for example, in order to operate the accessory device. For this purpose, the handheld power tool may have a transmission unit, in particular a bevel gear transmission unit. The transmission unit may transmit the movement of the drive unit to the tool receiving portion. In order to operate the handheld power tool, an operating element may be provided, which can be operated, in particular, so that the handheld power tool, in particular the drive unit, is placed in an operating state. In the actuated state, the drive unit can be placed, for example, into an operating state, in particular in order to drive an accessory device.

[0009] Operating unit for operating a hand-held machine tool

[0010] The operating unit can be designed in particular as an actuating unit and / or as a setting unit.

[0011] The operating unit can be provided for switching on / off the handheld power tool or the drive unit of the handheld power tool. The operating unit can have an operating element. The operating element can be configured as an operating handle. The operating element can be arranged on the machine housing, in particular on the handle area of ​​the machine housing. The operating element can extend along the longitudinal axis of the handheld power tool, in particular the machine housing. The operating element can extend along the longitudinal axis relative to the handle area of ​​the machine housing to 100%, in particular 90%, preferably 80%, advantageously 70%, particularly preferably 60%, and / or at least 20%, preferably at least 30%, advantageously at least 40%, particularly preferably at least 50%, further preferably at least 60%.

[0012] The adjustment unit can be configured to adjust the handheld power tool. The adjustment unit can lock, release and / or maintain the operation of the handheld power tool, in particular the drive unit of the handheld power tool, or the movement of the operating element. The adjustment unit can form a locking device. The operating unit can form a locking device. The adjustment of the adjustment unit can be set to operate the handheld power tool or the drive unit. The adjustment unit can constitute a switch lock.

[0013] The adjusting unit can have an adjusting element.

[0014] The machine housing can be configured to receive the operating unit. The machine housing can have housing half shells. The machine housing can be substantially designed in the form of a half-shell structure. The machine housing can surround the drive unit, the control or regulating unit, the transmission unit and / or at least partially surround the tool receiving portion.

[0015] The receiving unit may have a receiving portion which is provided for receiving a functional unit, in particular a functional element, and another functional unit, in particular another functional element. The receiving unit may form a receiving portion according to a shape, configuration, arrangement and / or number for receiving functional units.

[0016] The receiving unit and the machine housing may be designed integrally.

[0017] Functional unit for providing operational functions

[0018] An operating function is to be understood in particular as a function which is particularly required for manipulating and / or operating the handheld power tool, in particular the operating unit. The operating function can, for example, enable the release, operation, locking and / or resetting of the operating unit.

[0019] Alternative or optional functional units

[0020] “Different types” are to be understood as functional units that can be replaced, supplemented and / or exchanged with one another. In particular, the functional units should have essentially identical, similar and / or different functionalities and / or functional components. For example, the functional unit can exert a restoring force on the operating unit, in particular the adjustment unit, in order to reset the operating unit from an actuated state to a released state, in particular by means of a spring element.

[0021] For example, the other functional unit can exert a holding or locking force on the operating unit, in particular by means of a spring element, in order to hold the operating unit in the actuated state and / or the released state. It is therefore conceivable to provide a handheld power tool with a receiving unit for receiving two functional units, so that only one of the two functional units or both functional units can be provided.

[0022] Both functional units can be implemented in a single handheld power tool or in different handheld power tools.

[0023] For example, two functional units can be received by means of the receiving unit. The functional unit and the further functional unit can be arranged individually or separately in the receiving unit.

[0024] With the help of the present invention, a handheld machine tool with a machine housing can be provided, which can be used universally by allowing different or optional functional units to be received. In particular, different functional units can be arranged in the handheld machine tool with regard to different requirements and expectations of operators of the handheld machine tool. Because each functional unit requires the arrangement of the functional unit on the machine housing in order to meet the required function, the machine housing is provided with a corresponding receiving portion so that multiple functional units can be arranged on the machine housing. In other words, the machine housing can have different receiving units in a "redundant manner", which can be equipped with functional units when necessary. Therefore, even if the machine housing is not equipped with a first type of functional unit, but is equipped with a second type of functional unit, a receiving portion can be provided in the machine housing. The machine housing can thus be standardized. Resources and costs can thus be saved.

[0025] Therefore, there is no need to reconfigure the machine housing when the functional units are changed.

[0026] The dependent claims reveal further advantageous developments of the hand-held power tool according to the invention.

[0027] 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.

[0028] For example, the functional unit can be designed as a helical spring element. The functional unit can be coupled to an operating unit, in particular an operating unit and / or an adjustment unit. The functional unit can be arranged and / or clamped between a receiving unit or a machine housing and an adjustment unit. The functional unit can be arranged on the adjustment unit and / or coupled and / or clamped to the adjustment unit. The functional unit can be movably supported in the machine housing. The functional unit can be arranged in a recess of the adjustment unit in particular in each operating state.

[0029] For example, the further functional unit can be designed as a leaf spring element. The further functional unit can be coupled to the operating unit, in particular the operating unit and / or the adjustment unit. The further functional unit can be arranged and / or clamped between the receiving unit or the machine housing and the adjustment unit. The further functional unit can be arranged on the adjustment unit and / or coupled and / or clamped to the adjustment unit. The further functional unit can be movably supported in the machine housing. In the operating state, the further functional unit can be arranged in a groove (cutout) of the adjustment unit.

[0030] The adjusting unit can be provided for locking the actuating unit in an actuated state and / or a released state of the actuating unit.

[0031] Sustainable production of the machine housing can thereby be achieved in a particularly simple manner, whereby also faster process times can be achieved.

[0032] 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 another receiving area for receiving another functional unit. Furthermore, it may be expedient for the receiving area to be spaced apart from the other receiving area. This makes it possible to provide a particularly simple and compact receiving unit.

[0033] The receiving region can be provided for receiving a spring element, in particular a helical spring element. The further receiving region can be provided for receiving a further spring element, in particular a leaf spring element.

[0034] Furthermore, it may be expedient for the receiving area to be configured as a receiving groove and for the other receiving area to be configured as another receiving groove. The receiving unit may have a side wall. The receiving groove may be delimited by the side wall. The side wall may be arranged on the machine housing. The side wall may be surrounded by the machine housing. The side wall may be surrounded by the machine housing on the inside. The side wall may extend in the direction of the longitudinal axis of the machine housing, in particular the handle housing. The side wall may extend substantially perpendicularly to the machine housing. The side wall may extend transversely to, in particular perpendicularly to, the machine housing, in particular the inner surface of the machine housing. The side wall may delimit the receiving groove. The receiving area may be provided for being connected to the spring element, in particular in a form-locking manner. The receiving area may be provided for positioning the spring element on the machine housing.

[0035] In addition, it can be in accordance with the purpose that the machine housing has an adjustment groove for receiving the adjustment element. The receiving area can be arranged on one side of the adjustment groove, and another receiving area can be arranged on the other side of the adjustment groove away from the side. The adjustment groove can be arranged between the receiving area and the other receiving area. The adjustment groove can separate the receiving area from the other receiving area. The adjustment groove can extend through the machine housing. The adjustment groove can be constructed as a material penetration portion that passes through the entire material thickness of the machine housing. The receiving area and / or another receiving area can be connected to the adjustment groove or transition into the adjustment groove. The receiving area and the other receiving area can form a common receiving area with the groove. The adjustment groove can be provided for guiding the adjustment element.

[0036] Furthermore, it can be expedient for the spring element to overlap the adjustment groove and the adjustment element in the operating state, in particular in a direction transverse to the axis of motion of the adjustment element. Furthermore, it can be expedient for the other spring element to overlap the adjustment groove and the adjustment element in the operating state, in particular in a direction transverse to the axis of motion of the adjustment element. In the operating state, the spring element can be supported on the machine housing on one side and on the adjustment element on the other side. The spring element can be arranged in the adjustment groove in the gap between the adjustment element and the machine housing and / or extend beyond the gap. As a result, a particularly compact handheld machine tool can be provided.

[0037] Furthermore, it can be expedient for a further spring element to be arranged to act on the spring element. The further spring element can limit the movement of the spring element. Thus, the adjustment element can be held in the actuated state of the adjustment element by means of the further spring element, for example.

[0038] Furthermore, it may be expedient for the spring element to be arranged, in particular clamped, in a retaining recess of the adjustment element.

[0039] Furthermore, it can be expedient if the spring element is held, in particular in a direction transverse to the axis of movement of the adjusting element, by a holding recess of the adjusting element and a receiving recess of the machine housing.

[0040] Furthermore, it may be expedient for the functional unit to be designed as a deflection element, in particular a deflection element of a different type. The deflection element may be provided for actuating the switching unit. The deflection element may transmit, in particular a rotational movement, from the actuating unit to the switching unit. The deflection element may be provided for transmitting a movement from the actuating unit to the switching unit. The deflection element may be arranged at least partially, in particular effectively, between the actuating unit and the switching unit.

[0041] The functional unit can be configured as a deflection element. The further functional unit can be configured as a further deflection element. The deflection element can have a different configuration than the further deflection element. The deflection element can be exchanged with the further deflection element in such a way that the deflection element and the further deflection element can be arranged on the same receiving unit or support unit. In particular, the deflection element is configured such that the deflection elements can be arranged on the same receiving unit or support unit.

[0042] The deflection element can be coupled to the operating unit. The deflection element can be arranged and / or clamped between the operating unit and the switch unit. The deflection element can be arranged on the operating unit and / or coupled and / or clamped to the operating unit. The deflection element can be movably supported in the machine housing, in particular movably supported around the receiving unit. The deflection element can be arranged on the machine housing in particular in each operating state.

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

[0044] It may be expedient for the receiving unit to have a receiving area for receiving the functional unit.

[0045] In addition, it can be in accordance with the purpose that the receiving area has a receiving element configured as a receiving protrusion for receiving the deflection element, in particular each deflection element. The receiving protrusion can be configured substantially cylindrically, in particular bolt-shaped. The receiving unit can be surrounded by the deflection element, in particular completely surrounded, preferably in a 360° plane. The receiving element can be connected to the switch unit in a form-locking manner. The receiving element can position the switch unit on the machine housing. The receiving element can protrude laterally, in particular vertically, from the inner area of ​​the machine housing. The receiving protrusion can have a first end arranged on the machine housing. The first end can constitute a fixed end. The receiving protrusion can have a second end arranged on the machine housing. The second end can constitute a free end. The receiving protrusion can be configured to be inserted through the functional unit or the deflection element. For this purpose, the functional unit or the deflection element can have an insertion groove respectively.

[0046] The deflection element can transmit the movement of the operating unit to the switch unit. The deflection element can be mounted movably, in particular, about a deflection axis. The deflection element can be arranged between the operating unit and the switch unit. The deflection element can transmit the operating movement of the operating unit, in particular by means of an operating force, to the switch unit.

[0047] Thus, the receiving element can be provided for receiving different deflection elements. In this case, the deflection elements can be respectively adapted to the switches used, so that only the deflection elements are adapted and not the machine housing.

[0048] It may be expedient for the deflection element, in particular each deflection element, to be mounted rotatably relative to the receiving element. The receiving element or the bearing element may be designed to receive different types of deflection elements.

[0049] Furthermore, it may be expedient if the deflection element, in particular each deflection element, is arranged between the switching unit and the actuating unit, wherein the deflection element, in particular each deflection element, deflects a movement of the actuating unit onto the switching unit. This allows a particularly compact design to be achieved.

[0050] Furthermore, it can be expedient for the deflection element, in particular each deflection element, to have a contact element for contacting the actuation unit and a further contact element for contacting the switching unit. The contact element, in particular the contact point of the contact element, can be arranged spaced apart from the receiving element. The contact element, in particular the contact point of the contact element, can have different distances from the receiving projection.

[0051] Furthermore, it can be expedient for the contact element to be designed as a contact projection. The other contact element can be designed as another contact projection. Furthermore, it can be expedient for the deflection element, in particular each deflection element, to have an arc section connecting the two contact elements. The deflection elements can differ in the arrangement and / or construction of the contact elements of the deflection elements.

[0052] The invention also includes a system comprising a plurality of handheld power tools which have a deflection element or a further deflection element. BRIEF DESCRIPTION OF THE DRAWINGS
