Description

Technical Field

[0001] This invention belongs to the field of structural mechanics of tools, particularly portable and / or handheld tools, for optimizing impact and / or collision behavior. The invention relates to a housing component for an energy supply device for portable tools and / or portable power tools. Furthermore, the invention relates to a protective element for portable tools. Additionally, the invention relates to a tool, particularly a portable motor-driven tool, having at least one housing component and / or protective element. Background Technology

[0002] Tools, especially portable and / or handheld tools, are used in different fields and environments depending on their purpose, and therefore must meet different requirements and characteristics.

[0003] For example, in the case of tools in the form of portable, motor-driven power tools, there is a requirement to ensure sufficient stability and / or strength in the event of an impact or collision to avoid damage or destruction. In the case of manual operation, power tools are particularly susceptible to the risk of impact or collision due to improper handling (e.g., accidental drops).

[0004] To protect the tool units and / or equipment inside the tool from damage or destruction, the tool housing should be used first, and external accessories such as guardrails may also be used. This is especially important for chainsaws, particularly battery-powered trimmers, hedge trimmers, or cutters, as there may be relatively high drop heights, which in turn can result in high impact energy during a collision.

[0005] The challenge associated with portable power tools, in particular (such as chainsaws, cutters, hedge trimmers, electric sickles, brush cutters, blowers, etc.), is to strike a balance between two aspects: relatively low weight for good manual operability and sufficient rigidity to protect the internal tool unit from mechanical loads and ensure functionality. Summary of the Invention

[0006] The object of this invention is to provide a housing component for an energy supply device for portable tools and / or portable power tools, characterized by improved energy absorption characteristics, particularly improved energy absorption characteristics during impact. Furthermore, the object of this invention is to provide a tool and / or energy supply device having at least one such housing component.

[0007] Another object of the present invention is to provide a protective element for portable tools, characterized by improved energy absorption characteristics, particularly improved energy absorption characteristics during a collision, so as to protect, first and foremost, the tool housing, and also the tool unit and / or equipment inside the housing. Furthermore, an object of the present invention is to provide a tool having such a protective element.

[0008] This objective is achieved by the features of claims 1 and 11. Other embodiments and applications of the invention are derived from the dependent claims and are explained in more detail in the following description with reference to the accompanying drawings.

[0009] According to one general aspect, the present invention relates to a housing component for portable tools, particularly for a housing component for a portable motor-driven power tool and / or a power supply device for a portable power tool, the housing component having a functional structure for absorbing impact energy during a collision, wherein the functional structure includes a contact section arranged and configured to directly (immediately) absorb impact energy and deform; wherein the functional structure includes a deformation region arranged at the contact section and configured to receive the deformation of the contact section; and wherein the functional structure includes a stop section arranged and configured to limit the deformation of the contact section, particularly limiting the deformation of the contact section in a defined direction, and transmitting at least a portion of the impact energy.

[0010] The present invention provides a housing component with a functional structure, characterized in particular by improved energy absorption behavior during a collision (i.e., during a collision in both space and time). The collision can result from the housing component or a tool equipped with the housing component impacting the ground and / or colliding with another object. For example, through the construction of the functional structure, impact energy in the form of shock energy in the direction of impact can be eliminated by deformation in at least one defined direction relative to the direction of impact and / or during a defined duration.

[0011] Specifically, the contact section forms the active section of the functional structure, which moves during the collision. The stop section, in particular, is the passive section of the functional structure, which does not move relative to the contact section and / or the entire housing component during the collision and / or substantially does not change its original shape.

[0012] Specifically, due to its inherent characteristic of directly (immediately) absorbing impact energy, the housing component is an external housing component for portable tools. For example, the housing component can be configured to house and / or guide at least one section of other tool units containing a replaceable power supply device and / or the tool itself. Regarding the tool, the power supply device can be configured as a rechargeable battery that can be replaced manually and / or without tools. In other words, the tool can be configured to operate using a rechargeable battery that can be replaced manually and / or without tools.

[0013] For example, portable tools can be portable, motor-driven power tools in the form of chainsaws (especially pruning saws, cutters, electric sickles, blowers, or hedge trimmers). Of course, portable tools can also be configured and / or constructed for other purposes. Tools can be configured for garden, home, recreational, forestry, industrial, and / or agricultural applications.

[0014] The deformation zone at the contact segment is particularly located in an area directly adjacent to the contact segment, which is used for the deformation of the contact segment. For example, the defining direction for limiting the deformation of the contact segment can be a direction substantially parallel to the generated or idealized collision direction. Additionally or alternatively, the defining direction of deformation can be at least one direction inclined to the collision direction.

[0015] According to another aspect of the invention, it is possible to configure: the stop section is constructed to be substantially shape-stable, particularly to be substantially shape-stable up to a defined energy limit value of the impact energy, so as to disperse at least a portion of the impact energy; and / or the contact section is constructed to be partially shape-variable, particularly to be partially shape-variable up to a defined energy limit value of the impact energy, and is configured to perform deformation substantially reversibly.

[0016] In other words, the stop segment can be constructed to be substantially resistant to deformation, and is characterized by corresponding material strength and / or structural strength such that it is substantially non-deformable, particularly not substantially non-deformable up to a defined energy limit. Therefore, during a collision, it can effectively protect the tool unit and / or tooling adjacent to the stop segment from damage or destruction. The stop segment can be constructed to be sufficiently rigid and / or stiff.

[0017] The contact segment can be configured to be partially shape-deformable, such that at least a portion of the contact segment is substantially reversibly deformed up to a defined energy limit value for the impact energy, and thus substantially returns to its original shape after the impact process. For example, the energy limit value for the impact energy can be defined by the drop height of the tool, which has an integrated or housed energy supply device and is provided with a housing component. For example, the energy limit value can be defined based on a 5 kg power tool designed for a drop height of 5 m, approximately 247 joules.

[0018] The deformation zone can be arranged between the contact section and the stop section, such that a distance is formed between the contact section and the stop section, wherein the distance along the circumferential extension of the deformation zone is substantially constant or varies, and in particular has a defined maximum value.

[0019] In other words, the contact section, deformation zone, and stop section can be constructed in a sandwich structure. Therefore, the functional structure can be characterized by a double-wall arrangement.

[0020] The circumferential direction can characterize at least one direction and / or directional variation of the housing component, wherein the housing component, and thus the functional structure (particularly on the outer side), extends along this direction and / or directional variation. Since the distance between the contact segment and the stop segment is substantially constant or varies, the deformation behavior of the contact segment can be realized, and thus the defined energy absorption behavior of the functional structure can be achieved. Furthermore, the distance, particularly when it has a defined maximum value, can define and / or realize, for example, the maximum deformation path of at least a portion of the contact segment. Variations in the distance and / or the distance along the contact segment and / or the stop segment can characterize the construction of the deformation zone.

[0021] According to another aspect of the invention, the contact segment can be configured to include at least one predetermined fracture point, which is configured to cause a predetermined fracture of the contact segment when a predetermined energy limit value of the impact energy is reached and / or exceeded.

[0022] The predetermined fracture point can be the point at the contact segment that is damaged or destroyed during the impact, in order to absorb at least a portion of the impact energy, particularly preserving the remaining structure (other than the functional structure) of the stop segment or housing component without damage or destruction. The predetermined fracture point can be a localized limiting point at the contact segment, characterized, for example, by a relatively small thickness of the contact segment or a notch in the contact segment. For example, the defined energy limit can be determined by a drop test having a defined drop direction, thus having a defined impact direction, and / or having a defined drop height and / or having a defined tool position. The defined fracture can be a gewaltbruch (forced fracture).

[0023] The contact section, deformation zone, and / or stop section may be configured to be curved in a common direction; and / or in the front view, the deformation zone is characterized by an arc-shaped profile with a rounded transition between the contact section and the stop section.

[0024] For example, this can increase the stiffness of the functional structure while maintaining its energy absorption characteristics. For example, the rounded transitions can prevent the concentration of mechanical loads (e.g., in the form of stress) in the functional structure during a collision, and optimally disperse and / or transfer at least a portion of the impact energy to other points.

[0025] According to another aspect of the invention, it is possible to configure the deformation zone as a cavity, or to at least partially fill the deformation zone with a filling material, wherein the filling material is configured to suppress and / or delay the deformation of the contact segment in time.

[0026] By incorporating a portion with a deformation zone and filling material, the deformation zone (i.e., the filling material) can actively participate in and influence the deformation of the contact segment during the collision process. The filling material can be a foam material, such as a polyurethane-based foam material.

[0027] By using filler materials, the duration of deformation of the contact segment can be extended (i.e. delayed) in order to gradually eliminate impact energy.

[0028] The chamber can be configured to be closed or partially open in at least one direction.

[0029] The thickness of the contact segment can be substantially constant along its circumferential extension. In this case, the contact segment can be constructed as a simple wall segment with a substantially constant thickness.

[0030] Alternatively, the thickness of the contact segment may vary along the circumferential extension of the contact segment, and in particular, decrease (e.g., steadily decrease) from a defined maximum value to a defined minimum value, and in particular, subsequently increase (e.g., steadily increase) to the defined maximum value.

[0031] The contact segment can be a wall or wall segment of a functional structure, characterized by a varying thickness, wherein, in the circumferential direction, the thickness varies from a defined maximum value to a defined minimum value, so as to subsequently increase again to the defined maximum value. In other words, the thickness can be a varying wall thickness of the contact segment, wherein the contact segment narrows along its circumferential extension to a minimum wall thickness, then remains substantially constant if necessary, and then widens again.

[0032] For example, this enables defined, targeted, or intentional deformation behavior of the contact segment during a collision, wherein a region of the contact segment with a defined minimum thickness value dominates the deformation of the contact segment. This region of the contact segment with the defined minimum thickness value can be surrounded by the remaining regions of the contact segment in at least two directions.

[0033] According to another aspect of the invention, it is possible to provide that the contact section and the stop section have different stiffnesses, wherein, in particular, the stiffness of the stop section is greater than the stiffness of the contact section.

[0034] For example, the stiffness generated and / or idealized by the stop section can be at least twice that generated and / or idealized by the contact section.

[0035] This ensures that, during a collision, the absorption of impact energy is primarily achieved by the contact section combined with the deformation zone, and the stop section provides sufficient limitation on the deformation of the contact section.

[0036] The stiffness of the contact segment along its circumferential extension can be greater than the stiffness in at least one direction perpendicular to it. This can be achieved, for example, by using a fiber-reinforced plastic material that allows for targeted influence of stiffness characteristics in the respective directions.

[0037] The functional structure may include a reinforcing element configured to increase the stiffness of the stop section and to at least partially absorb and / or substantially counteract torsional loads that occur during a collision, wherein the reinforcing element is arranged on the side of the stop section opposite to the deformation zone, and / or wherein the reinforcing element is segmentally constructed as a hollow shaft or tube and extends substantially perpendicular to the circumferential direction and / or the deformation direction of the contact section.

[0038] The reinforcing element, which is directly constructed at or transitions to the stop section, can be characterized by a generally circular cross-section in the front view or at least in the sectional view. The reinforcing element can be connected to other reinforcing elements of the housing component, such as ribs, struts, grooves, and / or rolled edges.

[0039] According to another aspect of the invention, it is possible to configure the housing component and the functional structure as a single component, particularly by at least one injection molding process, at least one casting process and / or at least one lamination process; and the functional structure is configured to be semi-open and / or bottomless in a direction substantially perpendicular to the circumferential direction, and / or the contact section and / or the stop section are configured as strips and / or ribs, and extend in the circumferential direction respectively.

[0040] In other words, the functional structure can be an integral part of the housing components, and therefore an impact structure or collision structure of the housing components.

[0041] Additionally or alternatively, the housing components can be constructed using at least one 3D printing process or at least one sintering process. The housing components can be substantially constructed from a plastic-based material. The plastic can be injection-molded, castable, and / or curable. The stop section can be constructed at least partially from fiber-reinforced plastic.

[0042] According to another aspect of the invention, it is possible to arrange and / or construct at least one of the following elements at the stop section to support at least one tool unit and / or device of the tool in the installed state, particularly an energy supply device: ribs, supports, grooves, creases, protrusions and / or at least one semi-open chamber having, for example, a triangular or rectangular profile.

[0043] For example, this can increase stiffness at the defined points of the housing components to further improve the protection of the housing components for the tool unit and / or equipment, especially when mechanical loads occur during a collision.

[0044] According to another general aspect, the present invention relates to a tool, particularly a portable motor-driven power tool, having at least one housing component as disclosed herein, wherein the at least one housing component is arranged and configured to support and / or protect the power supply device of the tool in at least one collision direction, and in particular, the power supply device capable of manual and / or tool-free replacement.

[0045] Additionally or alternatively, at least one housing component can be arranged and configured to support and / or protect the drive unit of the tool during a collision in at least one collision direction, particularly a drive unit in the form of an electric motor.

[0046] According to another aspect of the invention, the tool can be configured to include a first housing component and a second housing component, wherein the first housing component and the second housing component are constructed substantially symmetrically with respect to the central plane of the tool, particularly with respect to the central plane of the channel for the energy supply device, and / or are constructed opposite to each other, wherein the functional structures extend segmentally in a direction substantially perpendicular to the central plane and / or are spaced apart from the central plane, in particular to provide at least one inlet for the operating elements of the tool.

[0047] According to another aspect of the invention, it is possible to configure: the first housing component and the second housing component respectively to form openings of a channel at their free ends, particularly for inserting an energy supply device in the insertion direction, and the functional structures of the first housing component and the second housing component are respectively arranged at their free ends so as to support the inserted energy supply device on the tool side adjacent to and / or adjacent to the opening during an impact, and to absorb and / or dissipate at least a portion of the impact energy around the energy supply device.

[0048] This is especially effective in protecting energy supply devices (such as those in the form of lithium-ion batteries) during a collision, thus preventing damage or destruction to the energy supply device.

[0049] The insertion direction can be the same as the insertion direction of the energy supply device.

[0050] According to another general aspect, the present invention relates to a protective element for portable tools, particularly for portable motor-driven power tools, for absorbing impact energy during a collision in the mounted state, wherein the protective element includes at least one coupling section and at least one locking section for tool-free mounting, particularly manual tool-free mounting, to at least one housing component of the tool, wherein the at least one coupling section is configured to form a first releasable connection with an associated mounting section of the at least one housing component; wherein the at least one locking section is configured to form a second releasable connection with an associated retaining section of the at least one housing component; and wherein the at least one coupling section is arranged and / or configured to carry out pivoting movement of the protective element about a pivot axis during mounting at the at least one mounting section.

[0051] In other words, the protective element is configured to be pivotally mounted on at least one housing component of the tool. Specifically, the mounting includes releasable fasteners and / or releasable fastener configurations. At least one housing component can be configured as disclosed herein.

[0052] The protective element according to the invention provides further improved impact and collision protection for tools, which can be optionally equipped with the protective element. The protective element is characterized in particular by simple manual installation, especially tool-free installation, and therefore also allows for manual tool-free removal.

[0053] Specifically, the protective element is a separate external impact or collision structure for portable tools, which can be used on the tool if needed.

[0054] The first releasable connection can be a first type of connection, and the second releasable connection can be a second type of connection that is different from the first releasable connection.

[0055] At least one coupling segment can be configured to partially plug into and / or hook onto an associated mounting segment.

[0056] This ensures that the protective element is confined to at least one housing component from the start of the installation process, thus providing a defined guide for the protective element for further installation, which in turn makes installation easier.

[0057] In other words, at least one coupling section has a pluggable, coupled-to-ground configuration and / or a pivotable, coupled-to-ground configuration at the mounting section. The hinge function between at least one housing component and the protective element can be achieved by (directly) hooking the protective element with the aid of at least one coupling section and the associated mounting section.

[0058] According to another aspect of the invention, it is possible to provide that the first releasable connection and / or the second releasable connection respectively comprise substantially form-fitting and / or substantially force-fitting connections, or at least are configured as substantially form-fitting and / or substantially force-fitting connections, wherein, in particular, the second releasable connection comprises a plug connection and / or a latching connection.

[0059] The latch connection can be configured as a releasable latch clamping connection, which can be formed during installation by applying pressure with a defined minimum pressure value to the protective element, i.e., in particular to at least one locking section.

[0060] At least one coupling section and at least one locking section may be arranged spaced apart from each other in the longitudinal direction of the protective element, wherein at least one coupling section is arranged in the longitudinal direction at the outer end of the protective element.

[0061] This ensures a secure and durable installation of the protective element at the pre-set point on the tool. Furthermore, the arrangement of at least one coupling segment at the outer end of the protective element, through the clear identifiability and relevance of its location, further simplifies the operation of installing the protective element onto at least one housing element.

[0062] The longitudinal direction is the direction in which the protective element extends the longest, thus maximizing its size.

[0063] According to another aspect of the invention, at least one coupling segment can be provided with a protrusion (particularly a rib) to form an undercut for pivotally supporting the protective element, the protrusion extending substantially transversely to the longitudinal direction of the protective element.

[0064] For example, by forming an undercut, it is ensured that the protective element will not slip or be accidentally released during installation. This also makes it easier to hook the protective element to at least one coupling section.

[0065] According to another aspect of the invention, it is possible to configure the protective element to be bent at least segmentally with a substantially constant thickness and / or with a variable thickness; and the protective element to be partially deformable in the bending region up to a defined energy limit value of the impact energy, particularly in a defined manner, especially in a defined manner, reversibly deformable.

[0066] For example, during or after a collision, following the deformation of the protective element, the element can essentially return to its original shape, at least segmentally. A defined stiffness, depending on the tool's configuration and construction, can be achieved through a bend with a substantially constant or varying thickness.

[0067] The protective element may be substantially constructed as a shell, cover, or basin, which transitions at least segmentally in the edge region along the circumferential direction to a contact flange for contacting at least one shell component, wherein, in particular, the contact flange is characterized by a defined transition radius in order to dissipate and / or transmit at least a portion of the impact energy.

[0068] The protective element can be constructed as a shell, a cover, or a basin. In particular, the area of ​​the contact flange with a defined transition region can be the bending region of the protective element.

[0069] The protective element may include a contact flange that extends at least segmentally in the circumferential direction and is configured to contact at least one housing component in the installed state.

[0070] Additionally or alternatively, the protective element may include at least one deformable section to directly absorb at least a portion of the impact energy and to deform, wherein the at least one deformable section is arranged and configured relative to a contact flange of the protective element for contacting at least one housing component, particularly in the installed state of the protective element, and in the installed state of the protective element, to construct a cavity, particularly a gap, relative to at least one housing component, which has a constant distance or a distance varying in the longitudinal direction of the protective element.

[0071] For example, through the deformation of at least one deformable segment, most of the impact energy can be dissipated and thus absorbed by the protective element. For example, the contact flange can transition directly to at least one deformable segment and / or be arranged adjacent to and / or spaced apart from at least one deformable segment in a defined manner.

[0072] It should be understood that the contact flange and / or at least one deformable segment used to construct the chamber can be constructed to be substantially complementary and / or substantially identical and / or similar to at least one housing component.

[0073] At least one deformable section can be constructed from the wall and / or wall section of the protective element.

[0074] According to another aspect of the invention, the contact flange can be configured to include at least one recess and / or at least one bend in the circumferential direction, respectively for constructing a cavity, in particular a gap, between the contact flange and at least one housing component, so as to disperse at least a portion of the impact energy at a defined point on at least one housing component in the installed state.

[0075] In particular, in order to construct at least one first deformable segment and at least one second deformable segment, the protective element may include a first sidewall and a second sidewall, which are arranged spaced apart from each other and / or arranged opposite each other, and extend in the longitudinal direction of the protective element, wherein the first sidewall and the second sidewall are respectively constructed as flat and / or plate-shaped, and / or wherein the first sidewall and the second sidewall are arranged obliquely to each other.

[0076] According to another aspect of the invention, it is possible to configure a first sidewall and a second sidewall to be connected to each other via a common rear wall extending in the longitudinal direction of the protective element, wherein the first sidewall, the second sidewall, and the rear wall are configured as gripping shells for manual installation of the protective element.

[0077] The rear wall may be constructed and / or arranged as a third deformable segment.

[0078] The reinforcing element may be arranged in the internal region of the protective element at the rear wall of the protective element. The reinforcing element is configured to be flat and / or plate-like, wherein, in the longitudinal direction of the protective element, the reinforcing element is arranged between at least one mounting section and at least one locking section.

[0079] According to another aspect of the invention, the protective element can be configured to include at least one recess that is closed in the circumferential direction and / or partially open in the longitudinal direction of the protective element, so as to respectively construct a defined stiffness of the protective element and / or realize an inlet for at least one operating element of the tool in the installed state.

[0080] The protective element can be integrally constructed as a single component and / or the protective element can be constructed from an elastic material, particularly by at least one injection molding process and / or at least one casting process.

[0081] According to another aspect of the invention, it is possible to provide that, in the longitudinal direction of the protective element, a first sidewall transitions to a first protective member, and a second sidewall transitions to a second protective member, wherein the first protective member and the second protective member are arranged spaced apart from each other and / or arranged opposite to each other, and wherein the first protective member and the second protective member are respectively configured to support and / or prop up the protective element in the direction of the pivot axis in the installed state.

[0082] According to another aspect of the invention, it is possible to configure at least one locking segment as a U-shaped protrusion in the front view, or to include a U-shaped protrusion that extends in a defined manner from a corresponding sidewall of the protective element into the internal region of the protective element to construct a latching element.

[0083] The protective element can be constructed in a manner that is substantially symmetrical with respect to the central plane.

[0084] According to another general aspect, the present invention relates to a tool, particularly a portable motor-driven power tool, having at least one first housing component, at least one second housing component, and a protective element as disclosed herein, wherein the protective element is releasably mounted at at least one first housing component and at least one second housing component under pretension to create a clamping force between at least one first housing component and at least one second housing component, particularly substantially in the direction of the pivot axis.

[0085] Alternatively or additionally, the clamping force may be formed between at least one first housing component and at least one second housing component by a protective element, wherein at least one coupling segment is constructed at the first housing component and an associated retaining segment is constructed at the second housing component.

[0086] At least one first housing component and / or at least one second housing component can be constructed as disclosed herein.

[0087] The tool can be configured to operate using a replaceable power supply (e.g., in the form of a manual tool-free installation, replaceable, rechargeable battery). The tool can be constructed as disclosed herein.

[0088] The tool can include at least one housing component with a functional structure according to the invention as disclosed herein, and a protective element according to the invention as disclosed herein.

[0105] In the accompanying drawings, identical or functionally equivalent devices, units, or elements are labeled with the same reference numerals. For the purpose of explanation, reference has also been made in part to the description of other embodiments and / or the accompanying drawings to avoid repetition.

[0106] The following detailed description of the embodiments shown in the accompanying drawings is intended to illustrate or explain in more detail, and is not intended to limit the scope of the invention. Detailed Implementation

[0107] Figure 1A first embodiment of the tool 1 according to the invention is shown in a perspective view. The tool has two housing components 10 and 20 according to the invention and an energy supply device 2 for the tool 1.

[0108] Tool 1 can be a portable power tool, a hand-operated power tool, an autonomous (electric grid-independent) power tool, and / or an electric motor-driven power tool. For example, Tool 1 can be constructed as one of the following: gardening tools, such as pruners, shears, sickles, blowers, or brush cutters; forestry tools, such as chainsaws; cleaning equipment, such as pressure cleaners; blowers or vacuum cleaners; or other electrical equipment, such as drills, cutters, saws, vacuum cleaners, or compressors. Other constructions and configurations of Tool 1 are possible.

[0109] In the illustrated embodiment, tool 1 is a portable, motor-driven power tool in the form of a motor-driven chainsaw, but for clarity, the saw chain and associated guide rails for the saw chain, which are the tool units of tool 1, are concealed. Here, chainsaw 1 is a so-called trimming saw.

[0110] The energy supply device 2 is constructed as a separate device and is configured to supply electrical power to the tool 1. The energy supply device 2 can be constructed as a portable, tool-free, manually installed, and / or replaceable battery, and can include, for example, multiple lithium-ion batteries.

[0111] Tool 1 includes a first housing component 10 and a second housing component 20. Furthermore, tool 1 includes additional housing components for forming the tool housing of tool 1, wherein additional housing components 30 and 40 are labeled for clarity. Additionally, housing components 10, 20, 30, and 40 serve to house the equipment and / or tool units and protect them from external influences, particularly mechanical loads in the form of impacts during collisions. It should be understood that tool 1 includes corresponding tool units, such as control devices, motors, lubrication tanks for saw chains, hand guards, handle tubes, operating handles with operating elements, etc., to achieve its intended function.

[0112] Housing components 10 and 20 are each constructed as a semi-shell shape and form a channel 2S in the installed state of the tool 1 for releasably accommodating the energy supply device 2 in the insertion direction S, which is the installation direction of the energy supply device 2. In other words, housing components 10 and 20 form a so-called cover for the tool 1. In the state of insertion into the channel 2S, and therefore in the installed state, the energy supply device 2 can be locked and released within the tool housing, particularly within housing components 10 and 20, by means of a manually operable operating element 50 in the form of a pivotally supported locking lever. There are additional operating elements in the form of locking levers for locking and releasing the energy supply device 2, but they are not shown for clarity. Housing components 10 and 20 and the operating element 50 are constructed and / or arranged substantially symmetrically with respect to the central plane E1 of the tool 1.

[0113] Tool 1 and energy supply device 2 are characterized by their respective weights based on their masses, and together they contribute to a total weight in the installed state, with energy supply device 2 accounting for a significant (i.e., non-negligible) share of the total weight. In particular, based on their masses and the resulting total weight, the tool housing must be constructed and configured accordingly to provide protection for energy supply device 2 and any other tool units it houses.

[0114] Since tool 1 is a portable, manually operated tool, it is also used at the corresponding working height (see also...). Figure 4 Therefore, tool 1 may be subjected to a collision, i.e., an impact, and thus be subjected to a brief mechanical impact load. For example, when tool 1 falls, a collision process with the ground B may occur, during which impact energy is generated, which is essentially absorbed by tool 1 during the collision process.

[0115] To protect the tool units and equipment, particularly the power supply equipment 2, arranged inside the tool housing from damage or destruction, in this embodiment, housing component 10 and housing component 20 respectively include functional structures 100 and 200 for absorbing impact energy during the collision with the ground B along the collision direction K1 (see also...). Figure 4 ).

[0116] The features of functional structure 100 described below are applicable to functional structure 200, and the features of functional structure 200 are applicable to functional structure 100.

[0117] Functional structure 100 is an impact structure or collision structure integrated into the housing component 10, and functional structure 200 is an impact structure or collision structure integrated into the housing component 20. Figure 1In particular, the functional structure 100 and its construction are visible. The functional structure 100 includes a contact segment 101, which is arranged and configured to directly (immediately) absorb impact energy and perform deformation. Thus, the contact segment 101 is a deformation segment, i.e., a deformation wall of the functional structure 100, whose corresponding geometry and / or material construction is designed to directly (immediately) absorb impact energy and eliminate it through deformation.

[0118] Functional structure 100 includes a deformation zone 103 disposed at the contact section 101 and configured to receive deformation of the contact section 101. Functional structure 100 includes a stop section 102 disposed and configured to limit deformation of the contact section 100 and to transmit and / or disperse at least a portion of the impact energy, more specifically, to transmit and / or disperse at least a portion of the impact energy to the housing member 10, other walls and / or wall sections of the housing member 20, and / or also to transmit and / or disperse to other housing members 30, 40 of the tool housing.

[0119] In this embodiment, the contact segment 101 and the stop segment 102 are respectively constructed as ribs or strips and extend along the circumferential direction U1. In particular, the circumferential direction U1 can be an outer circumferential direction U1, extending along the extension of the contact segment 100, especially occurring in and / or idealized as a plane substantially parallel to the central plane E1 (not shown in the figure). Figure 1 As shown, the functional structure 100 is configured to be half-open in a direction substantially perpendicular to the central plane E1.

[0120] A deformation zone 103 is arranged between the contact section 101 and the stop section 102, and is a cavity. The deformation zone 103 may be at least partially filled with a filler material, wherein the filler material is configured to inhibit and / or delay the deformation of the contact section 101 in time. For example, the filler material may be a foam material. The functional structure 100 is at least segmented and constructed as a sandwich structure, and is a so-called buffer zone.

[0121] At the stop section 102, a reinforcing element 110 is arranged and / or constructed, as well as additional wall and / or wall sections extending in the direction of the channel 2S as ribs, supports, grooves, flanges and / or webs.

[0122] Mounting section 11 is constructed at the first housing member 10, and mounting section 21 is constructed at the second housing member 20. Furthermore, retaining sections 230 and 430 are visible at housing members 20 and 40.

[0123] Mounting sections 11 and 21, together with retaining sections 230 and 430, are used to mount the individual protective element 3 to the tool housing, i.e., to housing components 10, 20, 30, and 40.

[0124] The protective element 3 and housing components 10, 20, 30, and 40 will be described in more detail below with reference to other accompanying drawings. The functional structure 100 will be described in more detail below with reference to partial V1.

[0125] Figure 2 Shown in cross-sectional view (side view) Figure 1 Tool 1. Figure 2 The front view shows the functional structure 200. The channel 2S for housing the energy supply device 2 can be clearly observed, which is defined in its opening area by a shell component 20 with corresponding ribs, webs and / or struts to enhance rigidity.

[0126] Functional structure 200 is similar in construction to functional structure 100 and includes a contact section 201, a stop section 202, and a deformation zone 203. Furthermore, a reinforcing element 220 is arranged and / or constructed at the stop section 202. Functional structure 200 will now be described in more detail with reference to partial V2.

[0127] Figure 3A It shows Figure 1 The magnified portion of tool 1, namely portion V1, shows the functional structure 100 in a stereoscopic view.

[0128] As a special wall section or deformable section of the functional structure 100, the contact section 101 is constructed to be partially shape-deformable, particularly up to a defined energy limit value for the impact energy. The contact section 101 can be configured to reversibly deform so as to substantially return to its original shape after the impact process. The energy limit value for the impact energy can be defined, for example, by the drop height of the tool 1 having an integrated (i.e., installed) energy supply device 2.

[0129] Due to the arrangement of the deformation zone 103 between the contact section 101 and the stop section 102, a distance A12 is formed between the contact section 101 and the stop section 102, which characterizes the deformation zone 103 in at least one direction and determines and / or limits the maximum deformation of the contact section 101 in at least one direction. The stop section 102 is constructed to be substantially shape-stable, particularly substantially shape-stable up to a defined energy limit value of the impact energy. In other words, the stop section 102 is a substantially rigid or deformation-resistant stop structure used to limit the deformation of the contact section 102 in at least one deformation direction.

[0130] The distance A12 can be substantially constant or variable along the extension of the deformation zone 103 in the circumferential direction U1, and in particular has a limited maximum value.

[0131] In this embodiment, the contact segment 101 includes a predetermined fracture point 110, the location of which is marked by a dashed line. The predetermined fracture point 110 is configured to cause a defined fracture, particularly a strong fracture, of the contact segment 101 when a predetermined energy limit value for the impact energy is reached and / or exceeded. The predetermined fracture point 110 is locally confined at the contact segment 101, particularly in the circumferential direction U1. For example, the predetermined fracture point 110 is characterized by a corresponding thickness D101 and / or corresponding material of the contact segment 101 in this region.

[0132] The contact section 101, the deformation zone 103, and the stop section 102 are each configured to bend in a common direction, particularly outward relative to the tool 1. For example, this can further increase the stiffness of the functional structure 100, while the functional structure 100 still retains its function as a buffer for the tool 1.

[0133] At the first end of the functional structure 100, the contact section 101 transitions to the stop section 102 via a transition section R11. Specifically, the transition section R11 can be a rounded transition section. Correspondingly, in Figure 3A At the second end that is not visible in the middle, the functional structure 100 can transition to the stop section 102 via another rounded transition portion.

[0134] The reinforcing element 120 is configured to further increase the stiffness of the stop section 102 and, in particular, to at least partially absorb and / or substantially counteract the torsional loads that occur during the collision process, wherein the reinforcing element 120 is arranged and / or constructed on the side of the stop section 102 opposite to the deformation zone 103. The reinforcing element 120 is segmentally constructed as a hollow shaft or tube and extends substantially perpendicular to at least one deformation direction of the circumferential direction U1 and / or the contact section 101. Furthermore, corresponding ribs, struts, grooves, and / or webs of the housing component 10 extend away from the reinforcing element 120 in the direction of the channel 2S; for clarity, these ribs, struts, grooves, and / or webs are not marked in more detail.

[0135] Figure 3B It shows Figure 2 The magnified local view of tool 1, namely local view V2, shows the functional structure 200 in a way that is essentially shown from the previous view (main view).

[0136] The front view shows the orientation of the contact segment 201, the stop segment 202, and the deformation zone 203 along the circumferential direction U1. In this view, the deformation zone 203 is characterized by an arc-shaped segmental profile with rounded transition portions R21 and R22 between the contact segment 201 and the stop segment 202, particularly in at least one deformation direction of the contact segment 201, so as to transfer at least a portion of the impact energy to the stop segment 202 without damaging or destroying the transmission point.

[0137] Along the circumferential extension U1 of the contact segment 201, the thickness D201_U1 of the contact segment 201 at a defined first circumferential position decreases (particularly steadily) from a defined maximum value to a defined minimum value D201_U2 at a defined second circumferential position, and then increases (particularly steadily) further in the direction to a defined third circumferential position D201_U3. For example, the defined maximum value can be the same as the regular and / or standardized wall thickness of the wall segment of the housing member 20, which supports the energy supply device 2 in the installed state. Figure 3B In the passage 2S, at least one such wall segment is adjacent to the functional structure 200, wherein, for example, two semi-open chambers with triangular profiles are constructed between the wall segment and the stop segment.

[0138] This achieves the construction of the contact segment 201, which is configured at a defined second circumferential position and / or in the region of the defined second circumferential position to maximize the deformation of the contact segment 201.

[0139] The contact section 201 can have a stiffness different from that of the stop section 202, and in particular, a stiffness less than that of the stop section 202, thus the contact section 201 is regarded as a deformation section of the functional structure 200. Alternatively, the thickness D201 of the contact section 201 can be substantially constant in the circumferential direction.

[0140] The thickness D202 of the stop section 202 can be at least equal to or greater than the thickness D201 of the contact section 201, which has a limited maximum value.

[0141] from Figure 3B The diagram also shows that the functional structure 200 is configured to be semi-open and / or without undercut in the direction substantially perpendicular to the central plane E1 and / or substantially perpendicular to the circumferential direction U1.

[0142] Figure 4 The collision process is shown in a stereoscopic view. Figure 1 A portion of tool 1 is shown. The energy supply device 2, housed in channel 2S, is idealized with a dotted label representing gravity G2 acting in the direction of ground B, according to the mass it generates. The generation and / or idealized gravity G1 of tool 1 in the absence of energy supply device 2 is also shown.

[0143] The collision process occurs in the generated and / or idealized collision direction K1 and is related to the contact segment 201 of the functional structure 200 that contacts the ground B.

[0144] Furthermore, the impact energy generated and / or occurring in this situation is produced by the total gravity (“total weight”) of tool 1 and energy supply device 2, and thus by the sum of gravity G1 and G2. The impact energy is absorbed by functional structure 200, wherein, during the collision process, contact segment 201 deforms at least partially within deformation zone 203 in the direction toward stop segment 202, which in Figure 4 The corresponding arrows indicate this. Due to the deformation of the contact section 201 in the deformation zone 203, at least a portion of the impact energy is absorbed and thus eliminated. The stop section 202 restricts the deformation of the contact section 201, but due to sufficient stiffness, the stop section 202 maintains a basically unchanged shape, thus maintaining a stable basic shape.

[0145] At least another portion of the impact energy can be transmitted and / or dispersed to the stop section 202 via the transition sections R21 and R22.

[0146] Due to the characteristics and relationships between the contact section 201, the stop section 202, and the deformation zone 203 described herein, a functional structure 200 is provided that is effective in terms of collision or impact behavior. The housing component 20 is characterized by this functional structure, which is particularly used to protect the energy supply device 2 from damage or destruction. This also applies to the housing component 10 having the functional structure 100.

[0147] The housing component 20 is integrally constructed as a single part with the functional structure 200. The housing component 20 can be constructed by at least one injection molding process, at least one casting process, and / or at least one lamination process. In particular, the stop section 202 can be constructed from a fiber-reinforced plastic material.

[0148] Figure 5 A first embodiment of the protective element 3 according to the present invention is shown in a perspective view.

[0149] The protective element 3 is configured to be mounted on the portable tool 1 disclosed herein, and in the mounted state, to absorb impact energy during a collision in order to provide extended protection for the tool element 1. In other words, the protective element 3 for the tool 1 is an additional and / or external collision or impact structure that protects the tool housing, particularly at least the housing components 10, 20, 30, 40, and the device 2 and / or tool unit housed within the tool housing.

[0150] The protective element 3 is configured for manual and / or tool-free installation onto housing components 10, 20, 30, and 40, and for this purpose includes two coupling sections 510 and 520 and four locking sections 610, 620, 630, and 640, wherein, in Figure 5In this configuration, except for coupling sections 510 and 520, locking section 640 is visible. Coupling sections 510 and 520 are respectively configured to form a first type of releasable connection 11, 510 and 21, 520 with their respective associated mounting sections 11, 21. Mounting sections 11, 21 are constructed at housing members 10 and 20, and for example in... Figure 1 and Figure 4 The middle is visible. Mounting sections 11 and 21 can be configured as edges or flanges, respectively.

[0151] Locking sections 610, 620, 630, 640 (see...) Figure 6 The second type of releasable connections 130, 610; 230, 620; 330, 630 and 430, 640 are constructed with the associated retaining sections 130, 230, 330, 430, which are located at the respective housing parts 10, 20, 30, 40. Retaining sections 230 and 430 are located at... Figure 1 The middle is visible, while sections 130 and 330 remain in Figure 7 The middle is visible. Each retaining section 130, 230, 330, 430 is constructed at the corresponding housing parts 10, 20, 30, 40, and is also a component of the screw cap (Schraubdom).

[0152] To explain in more detail, Figure 6 The previous view (main view) shows Figure 5 The protective element 3, among which, among others, locking sections 610, 620, 630, and 640 are visible.

[0153] The first type of releasable connections 11, 510 and 21, 520, and the second type of releasable connections 130, 610; 230, 620; 330, 630 and 430, 640, to be constructed and / or already constructed, are essentially form-fit connections, particularly plug-in or latch-in connections. Furthermore, the second type of releasable connections 130, 610; 230, 620; 330, 630 and 430, 640, to be constructed and / or already constructed, are essentially force-fit connections, particularly in the form of releasable latching connections. The latching connections 130, 610; 230, 620; 330, 630 and 430, 640 can be constructed by applying sufficient (external) installation pressure to the protective element 3 during installation onto the housing components 10, 20, 30, 40. Furthermore, the latch clamping connections 130, 610; 230, 620; 330, 630 and 430, 640 can be released by applying sufficient installation pull force to the protective element 3 during disassembly, so that the protective element 3 can be removed from the housing components 10, 20, 30, 40 again.

[0154] In order to construct latching connections 130, 610; 230, 620; 330, 630 and 430, 640 with the respective associated retaining sections 130, 230, 330, 430 of the corresponding housing components 10, 20, 30, 40, each locking section 610, 620, 630, 640 includes a latching element 611, 621, 631, 641 in the form of a protrusion. In the respective front view, the latching element is configured as a U-shape and extends in a defined manner from the respective sidewalls 514, 524 of the protective element 3 into the inner region 504 of the protective element 3. The corresponding latching elements 611, 621, 631, and 641 are located in the associated retaining sections 130, 230, 330, and 430 and / or in the associated retaining sections 130, 230, 330, and 430, i.e., within the corresponding screw caps, wherein additional clamping force is provided to fully secure the protective element 3.

[0155] The coupling segments 510, 520 and the locking segments 610, 620, 630, 640 are arranged spaced apart from each other in the longitudinal direction L3 of the protective element 3, wherein the coupling segments 510, 520 are arranged at the outer end of the protective element 2 in the longitudinal direction L3. In particular, the longitudinal direction L3 is the direction in which the protective element 3 extends the longest and thus extends the most in terms of its size.

[0156] The coupling sections 510 and 520 are configured to enable pivoting movement of the protective element 3 about the pivot axis A13 during installation onto the associated mounting sections 11 and 21. Specifically, the coupling sections 510 and 520 are configured to partially insert and / or hook onto the associated mounting sections 11 and 21. Each coupling section 510 and 520 includes protrusions 511 and 521, respectively, to form an undercut for pivotally supporting the protective element 3, wherein... Figure 5In the middle, the protrusion 521 of the coupling section 520 is visible. Protrusions 511 and 522 extend substantially transversely to the longitudinal direction L3 of the protective element 3 and / or substantially in the direction of the pivot axis A13, respectively. In particular, protrusions 511 and 521 are respectively constructed as ribs. The pivot axis A13 is defined in particular by the coupling sections 510, 520 and the associated mounting sections 11, 21. The coupling sections 510, 520 and the associated mounting sections 11, 21 are constructed substantially complementary to each other. In other words, the protective element 3 is configured to be pivotally mounted to the tool housing of the tool 1, which includes housing components 10, 20, 30, 40. This particularly ensures the ease of installation of the protective element 3 in a pivoting motion and subsequent latching process, wherein the protective element 3 is first inserted and / or hooked in an inclined position to the associated mounting sections 11 and 21 via coupling sections 510, 520 for pivotable support. Then, during pivoting about the pivot axis A13, the protective element 3 can be releasably, yet still securely, mounted to the housing components 10, 20, 30, 40 by constructing latching connections 130, 610; 230, 620; 330, 630.

[0157] The protective element 3 includes a contact flange 505 that extends at least segmentally in the circumferential direction U3 and is configured to contact housing components 10, 20, 30, and 40 in the installed state. The contact flange 505 may include at least one recess and / or at least one bend along the circumferential direction U3, respectively, for constructing a cavity, particularly a gap, between the contact flange 505 and the corresponding housing component 10, 20, 30, and 40, so as to transmit and / or disperse at least a portion of the impact energy at a defined point on the housing component 10, 20, 30, and 40 in the installed state.

[0158] Furthermore, the protective element 3 includes a plurality of deformable segments 500, 503, 514, and 524 in the form of walls and / or wall sections, wherein deformable segments 503, 514, and 524 are configured as sidewalls of the protective element 3, and deformable segment 500 is configured as the rear wall of the protective element 3, so as to directly (immediately) absorb at least a portion of the impact energy during a collision in the installed state, and to at least partially deform. The deformable segments 500, 503, 514, and 524 are arranged and / or configured relative to the contact flange 505 by defined positions and / or dimensions, and in the installed state of the protective element 3, form a chamber H23 relative to the corresponding housing components 10, 20, 30, and 40 (see...). Figure 9ASpecifically, at least one gap H23 is constructed, which has a constant distance or a varying distance in the longitudinal direction L3 of the protective element 3 relative to the housing components 10, 20, 30, and 40 (i.e., their outer surfaces). Thus, in the installed state, the protective element 3 provides an additional deformation possibility for the deformable segments 500, 503, 514, and 524, which further improves the protection of the tool 1 during a collision. See below for further details. Figure 9 and 9A The description was further explained.

[0159] The protective element 3 includes a first deformable segment 514 in the form of a first sidewall 514 and a second deformable segment 524 in the form of a second sidewall 524, which are arranged spaced apart from each other and / or opposite to each other, and extend in the longitudinal direction L3 of the protective element 3, respectively. The first sidewall 514 and the second sidewall 524 are respectively constructed to be substantially flat and / or plate-like. The first sidewall 514 and the second sidewall 524 are arranged obliquely to each other.

[0160] Furthermore, the first sidewall 514 and the second sidewall 524 are connected to each other via a third sidewall 503, which is another deformable segment 503 and 500, and a common rear wall 500. The rear wall 500 extends in the longitudinal direction L3 of the protective element 3.

[0161] Specifically, the first sidewall 514, the second sidewall 524, and the rear wall 500 are configured as gripping shells for manual installation of the protective element 3. Generally, the protective element 3 can be configured as a basin, shell, or cover.

[0162] The protective element 3 includes a recess 502 constructed in a closed manner in the rear wall 500 and a semi-open recess 501 constructed in the longitudinal direction L3 of the protective element 3, so as to respectively form a defined rigidity of the protective element 3 and / or realize an inlet for the operating element 50 of the tool 1 in the installed state.

[0163] The semi-open recess 501 is defined in the direction of the pivot axis A13 by a first sidewall 514 and a second sidewall 524. In the region of the semi-open recess 501, the first sidewall and the second sidewall form the shape of skids 513 and 523 along the longitudinal direction L3, or are characterized by a skid-like orientation. Furthermore, along the longitudinal direction L3, the first sidewall 514 transitions to the first protective member 512, and the second sidewall 524 transitions to the second protective member 522. The first protective member 512 and the second protective member 522 are arranged spaced apart from each other and / or opposite each other, and are respectively configured to support and / or reinforce the protective element 3 in the direction of the pivot axis A13 in the installed state, which further improves the fastening of the protective element 3 at the tool 1.

[0164] Furthermore, the protective element 3 may also include a reinforcing element 506 in its internal region 504, which may be configured as a plate and disposed at the rear wall 500. The reinforcing element 506 may help dissipate and / or transfer at least a portion of the impact energy along at least one defined direction.

[0165] In particular, the protective element 3 is integrally constructed as a single component. The protective element 3 can be constructed from an elastic material (e.g., a plastic-based elastic material), especially by at least one injection molding process and / or at least one casting process.

[0166] Figure 7 A perspective view showing the start of the installation process. Figure 1 Tool 1 and Figure 5 The installation process of the protective element 3 is schematically shown with dashed arrow lines. The protective element 3 is inserted into and / or hooked onto the associated mounting sections 11 and 21 of the housing parts 10 and 20 by means of coupling sections 510 and 520, and then toolless and / or manually pivoted to the housing parts 10, 20, 30 and 40 until the latching elements 611, 621, 631, 641 latch with the associated retaining sections 130, 230, 330, 430, so as to form the corresponding releasable latching connections 130, 610; 230, 620; 330, 630 and 430, 640, such that the contact flange 505 contacts the housing parts 10, 20, 30, 40, and the protective element 3 thus abuts against the tool housing.

[0167] The protective element 3 can be configured to be releasably installed under pretension to create clamping forces between housing components 10 and 20, 10 and 30, 10 and 40, 20 and 30, and / or 20 and 40, respectively. This improves the fastening of the protective element 3 at the tool 1 and makes it more resistant to vibrations, for example, that occur during the operation of the tool 1.

[0168] Figure 8 Shown in top view Figure 1 Tool 1. The respective semi-shell-like structures of housing components 10 and 20, the interior of the channel 2S with plate-like contact elements for accommodating and attaching the energy supply device 2, and the external structure and arrangement of functional structures 100 and 200 that cause the tool housing to bend and / or bulge can be clearly observed.

[0169] Figure 8A It shows Figure 8 The magnified local area of ​​tool 1, namely local V3.

[0170] The positions and structures of contact sections 101 and 201, stop sections 102 and 202, and deformation zones 103 and 203 located between them can be clearly observed. Figure 8A The illustration clearly shows that functional structures 100 and 200 are constructed and / or arranged substantially symmetrically with respect to the central plane E1.

[0171] Functional structures 100 and 200 extend in segments substantially perpendicular to the central plane E1 and / or are arranged at intervals relative to the central plane E1 to provide an entry point for the operating element 50 of the tool 1 for manual operation.

[0173] Figure 9A It shows Figure 9 The magnified portion of tool 1 and protective element 3, namely local V4.

[0174] The protective element 3 is in the installed state, which can also be observed from the visible latching connections 130, 610 and 230, 630 constructed between the locking sections 610, 620 and the associated retaining sections 130 and 230.

[0175] Contact flange 505 contacts housing components 10, 20, 30, and 40. The transition between the first sidewall 514 and contact flange 505 is characterized by a transition radius R505. The same applies to the transition between the second sidewall 524 and contact flange 505, wherein, for clarity, Figure 9A No further detailed markings were made in the text.

[0176] In addition, from Figure 9 and 9A As can be seen from the illustration, housing components 10 and 20 are connected to each other via a threaded connection S12, wherein each associated screw cap forms, or at least is a component thereof, retaining sections 130 and 230 associated with locking sections 610 and 630.

[0177] The side walls 514, 524 and / or the rear wall 500 are arranged and / or constructed together with the contact flange 505 such that, in the installed state of the protective element 3, a cavity H23 is formed between the respective walls 514, 524, 500 and the associated housing parts 10, 20, 30, 40 (i.e., their outer surfaces), particularly in the form of a gap H23. Figure 9A The location of the chamber H23 between the protective element 3 (i.e., the inner side of the rear wall 500) and the tool housing (i.e., housing parts 10 and 20) is shown.

[0178] For the walls 514, 524 and 500 used as deformation sections, the chamber H23 can be used as a deformation zone to receive the corresponding deformation during the collision process, thereby absorbing at least a portion of the impact energy.
