Description

[0001] Collecting container for workpiece particles, assembly comprising a motor-driven hand tool and a collecting container, motor-driven hand tool, and method

[0002] The invention relates to a collecting container for workpiece particles, which is intended for coupling to a motor-driven hand tool. The collecting container comprises a container body defined by an outer skin and a connecting piece for coupling the container body to the hand tool. The connecting piece has a free end that protrudes from the container body.

[0003] The invention is further directed to an assembly comprising a motor-driven hand tool and such a collecting container.

[0004] Furthermore, the invention is directed to a motor-driven hand tool for use in such an assembly.

[0005] Furthermore, the invention relates to a method for coupling a collecting container for workpiece particles and a motor-driven hand tool and to a method for decoupling a collecting container for workpiece particles and a motor-driven hand tool.

[0006] Such collection containers, assemblies, and motor-driven hand tools are known from the prior art. In this context, the outer skin of the container body is usually made of a material that is permeable to air but retains workpiece particles above a specified particle size. In other words, the outer skin acts as a filter to separate workpiece particles from air. Thus, an air-workpiece particle mixture resulting from material processing performed using the associated hand tool can be introduced into the collection container via the connection piece. The workpiece particles are retained in the collection container, so that the material processing causes comparatively little contamination.

[0007] Common collection containers are generally compatible with at least various motorized hand tools from the same manufacturer. If various motorized hand tools are required for material processing, the same collection container can be used. However, it must be detached from one hand tool when partially filled and then connected to another. Emptying the collection container also often requires disconnecting and reconnecting it from the associated hand tool.

[0008] In this context, it is known to equip the collection container with a locking mechanism that is spring-loaded into a closed position. Such locking mechanisms can be designed in such a way that, when the collection container is coupled to an associated hand tool, they are moved from the closed position to an open position against the spring load. When the collection container is uncoupled from the hand tool, the locking mechanism automatically returns to the closed position due to the spring load. However, collection containers with such locking mechanisms have the disadvantage that, upon uncoupling, a certain residual amount of workpiece particles is always released uncontrollably into the environment when the uncoupled collection container moves.

[0009] The object of the present invention is to eliminate or at least mitigate this disadvantage. Coupling and uncoupling the collecting container to a hand tool should remain simple. This object is achieved by a collecting container for workpiece particles, which is intended for coupling to a motor-driven hand tool. The collecting container comprises a container body, which is delimited by an outer skin, and a connecting piece for coupling the container body to the hand tool. The connecting piece has a free end that protrudes from the container body. The collecting container also comprises a connecting piece cover, which is rotatably mounted relative to the connecting piece and can selectively close or open the connecting piece. If the connecting piece cover closes the connecting piece, the connecting piece can also be referred to as closed or sealed.When the nozzle cover releases the connection nozzle, the connection nozzle can also be described as open. The nozzle cover can therefore be reliably closed. This prevents workpiece particles contained in the collecting container from being released into the environment in an undesirable manner. The rotatable mounting relative to the connection nozzle makes it easy to move the nozzle cover from an open state to a closed state and vice versa. It is understood that the rotatable mounting of the nozzle cover relative to the connection nozzle only allows a rotational movement of the nozzle cover relative to the connection nozzle. All other degrees of freedom of movement are blocked by the mounting.

[0010] As already explained, the nozzle cover serves to selectively close or open the connecting nozzle. The position of the nozzle cover relative to the connecting nozzle is irrelevant. This means that the nozzle cover can be located, for example, at the free end of the connecting nozzle, at an end of the connecting nozzle opposite the free end, or within the connecting nozzle. The nozzle cover can therefore also be referred to as a nozzle closure, although the terms nozzle cover and nozzle closure are used synonymously here.

[0011] The collecting container can also comprise a securing element by means of which the nozzle cover can be secured in a position in which it closes the connecting nozzle. The securing element can optionally assume a securing position in which it secures the nozzle cover in the position in which the nozzle cover closes the connecting nozzle. In addition, the securing element can optionally assume a releasing position in which it releases the nozzle cover so that it can be transferred from the position in which it closes the connecting nozzle to another position, in particular the position in which it releases the connecting nozzle. The securing element can comprise a linearly movable component or a rotationally movable component. The movable component is optionally spring-loaded or otherwise prestressed.The securing element comprises, for example, a securing hook, a securing lever, a securing clip, a securing pin, or another suitable means for securing the nozzle cover in the position in which it closes the connection nozzle. Using a securing element provides a particularly reliable way to prevent workpiece particles from escaping from the collection container.

[0012] Preferably, the safety element can be operated manually.

[0013] Depending on the specific application, the workpiece particles are also referred to as dust, e.g. grinding dust, or chips, e.g. sawdust.

[0014] The nozzle cover can be rotatable about a rotation axis that runs transversely to a longitudinal direction of the connecting nozzle. In other words, the rotation axis runs parallel to a tangential direction on an outer circumference of the connecting nozzle. A nozzle cover mounted in this way can, on the one hand, be easily converted from the open state to the closed state and vice versa. On the other hand, the nozzle cover can reliably seal the connecting nozzle in the closed state.

[0015] In one example, the nozzle cover can be rotated about an axis of rotation which, when the collecting container is in its use position, is either substantially horizontal or substantially vertical. A collecting container's use position corresponds to the position the collecting container assumes when it is coupled to an associated hand tool and the hand tool is in a normal or reference position. A processing zone lies along a vertical direction below the hand tool used to perform the processing. Thus, the processing zone also lies vertically below the collecting container. Information on the processing zone and the use position refers to this case. It goes without saying that some hand tools, which may also be equipped with collecting containers, also allow vertical or overhead work.However, such working positions are considered an exception in the present case and are not used as a reference. In the use position, a central axis of the connecting piece usually has a horizontal extension component. Preferably, the horizontal extension component is greater than a vertical extension component of the central axis of the connecting piece. More preferably, the horizontal extension component of the central axis of the connecting piece is at least twice as large as the vertical extension component. In this context, the connecting piece cover must be rotated about the essentially horizontal or essentially vertical axis of rotation in order to optionally close or release the connecting piece. From a user perspective, such rotatability is particularly simple and intuitive. Thus, a connecting piece cover mounted in this way can be operated particularly easily and reliably.

[0016] The nozzle cover can optionally close or open the connection nozzle at the free end. The nozzle cover therefore closes the connection nozzle at the end that protrudes from the container body. Consequently, when the nozzle cover is closed, at least those sections of the connection nozzle through which an air-workpiece particle mixture flows during operation of the collection container are located on the same side of the nozzle cover as the container body. In other words, when the nozzle cover is closed, those sections of the connection nozzle through which an air-workpiece particle mixture flows during operation of the collection container are separated from the surroundings of the collection container by the nozzle cover. Therefore, no workpiece particles can escape from this section of the connection nozzle. Undesirable contamination can thus be particularly reliably excluded.A further advantage of this configuration is that, when open, the nozzle cover can be positioned outside the sections of the connection nozzle through which an air-workpiece particle mixture flows during operation of the collection container. In other words, such flow is not obstructed or restricted by the nozzle cover.

[0017] According to one variant, the nozzle cover can selectively close or open the connection nozzle at an end on the container body side. The container body-side end of the connection nozzle is arranged opposite the free end of the connection nozzle. In other words, the connection nozzle can be selectively closed or opened at the end adjacent to the container body. This has the advantage that the nozzle cover can be arranged at least partially within the container body and / or within the connection nozzle. In this way, the nozzle cover can be protected from undesirable external influences, e.g., mechanical ones. At the same time, this prevents the nozzle cover from interfering with the handling of the collection container.A further advantage of a nozzle cover that can selectively close or open the connection nozzle at one end of the container body is that such a nozzle cover can open or close the connection nozzle regardless of the coupling state of the collecting container. This means that, in particular, when the collecting container is coupled to the motor-driven hand tool, the connection nozzle can be closed. Thus, when the collecting container is coupled to the motor-driven hand tool, workpiece particles present in the collecting container can be reliably prevented from leaving the collecting container and / or, possibly via the hand tool, from entering the environment.When the nozzle cover is in the closed position, at least a portion of the nozzle cover can rest against or be opposite the inner circumference of the connecting nozzle. Consequently, the collection container can be reliably closed. Any unwanted escape of workpiece particles is effectively prevented.

[0018] According to one embodiment, the nozzle cover is mounted on the connecting nozzle. The nozzle cover is thus mounted on the component of the collecting container that the nozzle cover can selectively open or close. This is structurally particularly simple. Furthermore, the maximum dimensions of a collecting container are generally defined by the container body. Accordingly, the connecting nozzle is normally set back, at least in sections, from an outer shell of the collecting container. This means that a nozzle cover mounted on the connecting nozzle does not increase the overall dimensions of the associated collecting container at all or only insignificantly. Handling of the collecting container is thus only slightly or not at all impaired by the nozzle cover.

[0019] According to one variant, the nozzle cover is mounted on the connecting nozzle via a bearing block. The bearing block is positioned on the outer circumference of the connecting nozzle. This provides the nozzle cover with a stable and reliable mechanical support. It can thus be moved from the open to the closed position and vice versa with high reliability. Furthermore, this type of bearing arrangement has a long service life.

[0020] In another variant, the nozzle cover is mounted on the outer skin outside the connection nozzle. In this variant, too, the nozzle cover is mounted in a mechanically stable and reliable manner. It can thus be transferred from the open state to the closed state and vice versa with high reliability. Furthermore, this type of mounting has a long service life. Mounting on the outer skin has the advantage that any disruptive influence of the nozzle cover on the coupling of the connection nozzle to the hand tool or on the decoupling of the connection nozzle from the hand tool can be eliminated or at least reduced.

[0021] The nozzle cover can be mounted on an outer side of the outer skin. Consequently, the nozzle cover can be easily mounted and removed from the outer skin. This configuration is therefore easy to maintain and repair.

[0022] It is also possible for the nozzle cover to be mounted on the inside of the outer skin. The nozzle cover's bearings are therefore protected from undesirable environmental influences by the outer skin.

[0023] According to an alternative, the nozzle cover is mounted on the outer skin via a bearing block that protrudes from the outer skin toward the interior of the container body. Such a mounting offers the possibility, particularly in a release position of the nozzle cover in which the nozzle cover releases the connecting nozzle, of arranging the nozzle cover outside, in particular at a distance from, a container-body-side end of the connecting nozzle, i.e. outside, in particular at a distance from, a container-body-side opening of the connecting nozzle. This eliminates any potential impairment of the flow of an air-workpiece particle mixture from the connecting nozzle into the container body.

[0024] In one embodiment, the nozzle cover is preloaded into a closed position by a spring device, in which the nozzle cover closes the connecting nozzle, particularly at the free end. The nozzle cover thus assumes the closed state when no forces other than the preload force act on it and the assumption of the closed state is not otherwise blocked. This prevents workpiece particles from undesirably escaping from the collection container.

[0025] The spring device comprises, for example, a leg spring made of metal. The nozzle cover can comprise a closure section and an actuating section offset therefrom, wherein the actuating section is designed for manually releasing the connecting piece, in particular the free end of the connecting piece. The closure section and the actuating section are therefore separate sections of the nozzle cover. The closure section and the actuating section can be formed integrally on the same component. Alternatively, the closure section and the actuating section are realized by two separate components that are coupled to one another. In both alternatives, the nozzle cover can be actuated particularly easily thanks to the actuating section. Furthermore, the connecting piece can be reliably closed thanks to the closure section.

[0026] Preferably, the locking portion and the actuating portion form an obtuse angle in a rotational plane. The included angle is the smallest angle formed by the locking portion and the actuating portion when viewed along the rotational axis. The actuating portion is thus always easily accessible. Furthermore, the associated actuating force can be conveniently applied.

[0027] The actuating section and the locking section can be positioned on opposite sides of the rotation axis. This also ensures good accessibility to the actuating section. Furthermore, in this variant, the actuating section forms an actuating lever, which, due to the leverage effect, allows the locking section to be actuated with comparatively low forces.

[0028] According to one embodiment, the axis of rotation is spaced from the outer circumference of the connecting piece, such that the actuating section, when viewed along the axis of rotation, is movable to a side of the axis of rotation facing the connecting piece. The actuating section can therefore be moved, at least in sections, closer to the connecting piece than the axis of rotation is away from the outer circumference of the connecting piece. As a result, the closure section can be brought into a position in which, when viewed perpendicular to a cross-section of the free end of the connecting piece, it lies outside the cross-section. In particular, in this position and when viewed in this manner, the closure section has a distance greater than zero from an outer circumference of the cross-section of the connecting piece. In simple terms, the connecting piece cover can be opened very wide.This ensures that the nozzle cover does not interfere with the coupling of the collection container to an associated hand tool or the decoupling of the collection container from the associated hand tool. In other words, there is plenty of space for coupling and decoupling.

[0029] In one embodiment, the closure section and the actuating section are connected via an actuating arm. Depending on the configuration, the actuating arm can be designed to be subjected to tensile, compressive, bending, and / or torsional stress to adjust the nozzle cover between the closed position and the release position. In all variants, the actuating arm serves to transmit an actuating force or torque acting on the actuating section into the closure section, so that the latter optionally closes or releases the connecting nozzle. In this context, the provision of an actuating arm allows the closure section and the actuating section to be spaced apart from one another and / or arranged in different spatial orientations. In other words, the actuating arm facilitates integration of the nozzle cover into a collecting container.

[0030] According to one variant, the outer skin has a through-opening. The nozzle cover extends through the through-opening, so that the actuating section and the closing section are positioned on opposite sides of the outer skin. This allows a nozzle cover whose closing section is positioned inside the outer skin to be operated reliably and easily.

[0031] In the release position, in which the nozzle cover releases the connection nozzle, the actuating section of the nozzle cover can conform to an outer side, in particular an outer circumference, of the connection nozzle or to an outer side of the outer skin. Conforming here means that at least a section of the actuating section at least substantially follows a local contour or a local profile of the outer side. In this context, the actuating section can have a section whose shape is similar to a section of the connection nozzle or a section of the outer skin. In particular, the actuating section can have a section that is curved or bent in such a way that it conforms to an outer circumference of the connection nozzle when the nozzle cover is in the release position. Optionally, the section of the actuating section bears against the outer side of the connection nozzle or the outer side of the outer skin.The actuating section is thus arranged compactly in the release position. Furthermore, the actuating section protrudes little or not at all from the outer shell of the collection container. This facilitates handling of the collection container. Furthermore, this positioning of the actuating section makes it easy and reliable for the user to recognize when the release position has been reached.

[0032] The connection piece can have a sealing section on its inner circumference, particularly adjacent to the free end. This allows the collection container to be reliably coupled to an associated hand tool. Any unwanted escape of workpiece particles in the coupling area is effectively prevented.

[0033] The nozzle cover can also have a sealing section on the cover side, which is designed to be at least partially opposite the connection nozzle-side sealing section in the closed position or to rest against the connection nozzle-side sealing section. Consequently, the collection container can be reliably closed. Any unwanted escape of workpiece particles is effectively prevented.

[0034] Preferably, at least one of the cover-side sealing section and the connection piece-side sealing section has a sealing element. This further increases the already mentioned high reliability of the seal. This significantly prevents unwanted escape of workpiece particles. According to an alternative, a retaining rib is provided on the nozzle cover to lock the collection container in a position coupled to the motor-driven hand tool. The collection container can thus be reliably coupled to the hand tool using the nozzle cover. The nozzle cover therefore has two functions. On the one hand, it serves to close the collection container in a situation in which it is decoupled from a hand tool. On the other hand, it serves to securely and reliably lock the collection container to the hand tool when the hand tool is coupled to the hand tool.

[0035] The retaining rib can be located on the locking section. This allows the collection container to be reliably locked to the hand tool.

[0036] In one variant, the retaining rib is positioned on a side of the closure section facing the connecting piece. This means that when the connecting piece is closed by the cover, the retaining rib is located inside the connecting piece. In other words, the retaining rib does not interfere with handling of the closed collection container. On the other hand, this positioning of the retaining rib enables simple and reliable locking of the collection container to the hand tool.

[0037] The retaining rib can have a mounting bevel. This facilitates the achievement of a state in which the collection container is locked to the hand tool by means of the nozzle cover. By bringing the mounting bevel into contact with an element on the hand tool designed to interact with the retaining rib, the retaining rib can be adjusted to a position required to lock the collection container to the hand tool.

[0038] According to one embodiment, a recess is provided on the nozzle cover for accommodating a portion of the hand tool when the collection container is coupled to the motor-driven hand tool. This allows the collection container to be coupled to the hand tool particularly reliably. Furthermore, this allows the nozzle cover to assume a position close to an outer contour of the hand tool when the collection container is coupled to the hand tool. This facilitates handling of the assembly comprising the collection container and hand tool.

[0039] The recess can be located on the closure section. This allows for a space-saving and reliable connection of the collection container to the hand tool.

[0040] In one variant, the recess is positioned on a side of the closure section facing the connecting piece. This means that when the connecting piece is closed by the cover, the recess is located inside the connecting piece. In other words, the recess does not interfere with handling of the closed collection container. Furthermore, this type of positioning of the recess enables a simple and reliable coupling of the collection container to the hand tool.

[0041] The retaining rib can be positioned closer to the nozzle cover's rotation axis than the recess. This allows the collection container to be reliably coupled to the hand tool and locked in place. Furthermore, this configuration saves space.

[0042] Preferably, in a release position in which it releases the connecting piece, in particular at the free end, the nozzle cover encloses an angle of greater than 90° with a connection cross-section of the connecting piece. This angle is preferably measured around the rotation axis of the nozzle cover. Put simply, the nozzle cover can be opened very wide. This ensures that the nozzle cover does not hinder coupling the collection container to an associated hand tool or decoupling the collection container from the associated hand tool. In other words, a large amount of space is available for coupling and decoupling. The same effect is also achieved if the rotation axis of the nozzle cover is at a comparatively large distance from an outer circumference of the connecting piece. In such a configuration, the nozzle cover can enclose an angle of greater than 90° with the connection cross-section of the connecting piece in the release position.Alternatively, it is also conceivable that the angle is 90° or less than 90°.

[0043] The connection piece can be provided on a dimensionally stable section of the outer skin. Due to the dimensionally stable section, the collection container has a fixed geometry in the area of ​​the connection piece. This facilitates coupling and uncoupling of the collection container to and from the hand tool.

[0044] The rigid section and the connecting piece can be manufactured as a single piece. This is efficient from a manufacturing perspective. Assembly operations for coupling the rigid section to the connecting piece are not necessary.

[0045] In one variant, the outer skin has a light incidence section that is translucent. Furthermore, the outer skin has a viewing window section that is transparent. At least one point of the light incidence section is connected to at least one point of the viewing window section by a straight line of sight. A user of the collecting container and a hand tool coupled thereto can thus determine the current fill level by looking through the viewing window section into the interior of the collecting container. Light can enter the interior of the collecting container through the light incidence section. Consequently, that area of ​​the interior of the collecting container is illuminated by light that enters via the light incidence section. The current fill level of the collecting container can thus be determined with high precision and reliability. At the same time, all other sections of the outer skin, i.e.All sections except the light incidence section and the viewing window section are permeable to air and can perform the desired filtering function for separating workpiece particles above a specified particle size from air. Optionally, the light incidence section is also permeable to air and acts as a filter. It should be emphasized that the light incidence section is a section of the outer skin and therefore always contains outer skin material. In other words, the light incidence section is not designed as an opening. The filtering effect is therefore only slightly influenced by the viewing window section and, if applicable, the light incidence section.

[0046] In one variant, an emptying opening for removing workpiece particles from the container body is arranged in the outer skin, and an emptying direction associated with the emptying opening extends from the interior of the container body through the emptying opening. The emptying direction is substantially perpendicular to an opening cross-section of the emptying opening. Furthermore, a closure means is provided which can be fastened to the container body at least in a closed position, so that the emptying opening can be selectively closed by means of the closure means. In a use position of the collecting container, when the closure means is in an open position, the emptying direction has an extension component pointing vertically in the direction of a processing zone. In the closed position of the closure means, the emptying opening is closed by means of the closure means. In the open position, the emptying opening is released.In the open position, the closure means can be connected to the container body or separated from the container body. A usage position of the collection container corresponds to the position which the collection container assumes when it is coupled to an associated hand tool and the hand tool is in a normal position or reference position. In this case, a processing zone lies along a vertical direction below the hand tool with which the processing is carried out. The processing zone is therefore also located vertically below the collection container. Information on the processing zone and the usage position refer to this case. It is understood that with some hand tools, which may also be equipped with collection containers, work in a vertical position or overhead is also possible. However, such working positions are regarded as an exception in the present case and not used as a reference.In the use position, a central axis of the connecting piece typically has a horizontal extension component. Preferably, the horizontal extension component is greater than a vertical extension component of the central axis of the connecting piece. More preferably, the horizontal extension component of the central axis of the connecting piece is at least twice as large as the vertical extension component. In the use position of the collecting container, the emptying direction thus has an extension component that points vertically downwards. Workpiece particles present within the collecting container can thus leave the interior of the collecting container through the emptying opening by utilizing gravity. The collecting container can remain connected to the associated hand tool, while the hand tool can assume its normal position.In other words, the hand tool with the attached collection container does not have to be placed in an ergonomically uncomfortable position. This makes emptying the collection container particularly easy. The fact that the emptying direction extends vertically downwards also means that the workpiece particles can be emptied directly into a container positioned below the collection container. This prevents unwanted contamination from workpiece particles.

[0047] The dimensionally stable section can be designed as a closure means for selectively opening or closing the emptying opening in the outer skin of the container body. The collection container can thus be selectively opened for emptying using the closure means.

[0048] According to one embodiment, the container body comprises a folding mechanism so that the container body can either assume a working position in which the outer skin encloses a first volume, or a transport position in which the outer skin encloses a second volume. The second volume is smaller than the first volume. In the working position, a first outer skin length dimension has a greatest length compared to the other outer skin length dimensions. In the transport position, the first outer skin length dimension defines a greatest length of the container body. In this context, an outer skin length dimension is understood to mean a length dimension of the outer skin. The orientation of the length dimension in space is not important. Depending on the spatial orientation of the container body, an outer skin length dimension can therefore be a length, a width, or a height.Furthermore, an outer skin length dimension can be defined between any pairs of surfaces, edges, and corners of the outer skin. Dimensions of surfaces and edges of the outer skin also fall under the term outer skin length dimension. For example, an outer skin dimension extends along an edge of the outer skin. The collection container according to the invention is therefore characterized in that a greatest length of the container body in the transport position is defined by that outer skin length dimension in the working position which has the greatest length in the working position. In other words, the container body can be folded using the folding mechanism in such a way that the greatest outer skin length dimension in the working position, which does not necessarily have to be the largest overall dimension of the container body, becomes the largest overall dimension of the container body in the transport position.The container body does not increase in length in any way due to folding. This allows for a good compromise between the largest possible volume of the container body in the working position and the smallest possible volume of the container body in the transport position. Ideally, the volume in the transport position is zero.

[0049] The problem is further solved by an assembly comprising a motor-driven hand tool and a collecting container according to the invention. The collecting container is fluidly coupled to the hand tool via the connecting piece, so that an air-workpiece particle mixture can be introduced from the hand tool into the collecting container. The connecting piece cover of the collecting container according to the invention is in an open state. It lies outside the sections of the connecting piece through which an air-workpiece particle mixture flows during operation of the collecting container. In other words, such a flow is not impeded or restricted by the connecting piece cover.The rotatable bearing on the connection piece also makes it easy to move the piece cover from an open state to a closed state when the collection container is uncoupled from the hand tool, and vice versa when the collection container is to be coupled to the hand tool.

[0050] The nozzle cover of the collection container can at least partially contact the contact area of ​​the hand tool. The nozzle cover thus assumes a defined position.

[0051] Alternatively or additionally, the nozzle cover can engage behind a retaining ridge on the hand tool, locking the collection container to the hand tool. This makes the connection between the collection container and the hand tool particularly secure and reliable. In particular, the retaining rib on the nozzle cover engages behind the retaining ridge on the hand tool.

[0052] The retaining bead can have a mounting bevel. This makes it easier to achieve a state in which the collection container is locked to the hand tool by means of the nozzle cover. By the mounting bevel on the retaining bead coming into contact with an element of the nozzle cover designed to interact with the retaining bead, the nozzle cover can be adjusted to a position required to lock the collection container to the hand tool.

[0053] The object is also achieved by a motor-driven hand tool for use in an assembly according to the invention. The motor-driven hand tool comprises an outlet for discharging an air-workpiece particle mixture, wherein a retaining bead for coupling a collecting container for workpiece particles is arranged on an outer circumference of the outlet. This collecting container is in particular the collecting container according to the invention. By means of the retaining bead, the collecting container can be coupled to the hand tool with particularly high reliability and locked there. In addition, the object is achieved by a motor-driven hand tool that is particularly suitable for use in an assembly according to the invention. The motor-driven hand tool comprises an outlet for discharging an air-workpiece particle mixture.In addition, the motor-driven hand tool has an outlet closure that is rotatably mounted relative to the outlet and can selectively close or open the outlet. By means of such an outlet closure, in a case in which a collecting container is coupled to the outlet, a flow connection between the outlet and the collecting container can be selectively opened or interrupted by means of the outlet closure. When the outlet closure is closed, no workpiece particles can pass from the collecting container into the interior of the motor-driven hand tool. Also, no air-workpiece particle mixture can pass from the motor-driven hand tool into the collecting container. This applies in particular when the collecting container and the motor-driven hand tool are coupled to one another and the collecting container does not have a nozzle cover.This means that a particularly simple collection container can be used.

[0054] In this context, the outlet closure can be designed according to any of the aforementioned nozzle cover designs. This means that all the above explanations regarding the nozzle cover also apply to the outlet closure.

[0055] Furthermore, the object is achieved by a method for coupling a collecting container for workpiece particles and a motor-driven hand tool. The collecting container has a container body for receiving workpiece particles, which is delimited by an outer skin. Furthermore, the collecting container has a connecting piece for coupling the container body to the hand tool. The method comprises:

[0056] Connecting the connection piece and the hand tool, whereby the

[0057] The connecting piece is closed by means of a nozzle cover, and the connecting piece is subsequently released by moving the nozzle cover from a closed position to a released position.

[0058] This ensures that when the collection container is connected to the motor-driven hand tool, workpiece particles cannot escape uncontrollably. The connection piece is only released once the collection container and the motor-driven hand tool are connected.

[0059] The method for coupling a collecting container for workpiece particles and a motor-driven hand tool can be carried out in conjunction with a collecting container according to the invention and / or in conjunction with a hand tool according to the invention.

[0060] Furthermore, the problem is solved by a method for decoupling a collecting container for workpiece particles from a motor-driven hand tool. The collecting container has a container body for receiving workpiece particles, which is delimited by an outer skin. Furthermore, the collecting container has a connecting piece for coupling the container body to the hand tool. The method comprises:

[0061] • Closing the connection piece using a piece cover, and

[0062] • Subsequent separation of the connection piece and the hand tool.

[0063] This process also ensures that when the collection container for workpiece particles and the motor-driven hand tool are decoupled, workpiece particles cannot leave the collection container in an uncontrolled manner.

[0064] The method for decoupling a collecting container for workpiece particles and a motor-driven hand tool can be carried out in conjunction with a collecting container according to the invention. Furthermore, the object is achieved by a method for transporting an assembly comprising a motor-driven hand tool and a collecting container. In particular, the assembly is an assembly according to the invention. The collecting container is coupled to the hand tool, i.e., mechanically connected. Furthermore, the collecting container and the hand tool are at least temporarily blocked from one another in terms of flow. In this context, the coupling of the collecting container and the hand tool can be achieved by connecting an outlet of the hand tool to a connection piece of the collecting container.The outlet and the connection piece are fluidically coupled provided that a nozzle cover of the collecting container and / or an optional outlet closure provided at the outlet are in a released state, i.e., they fluidly release the connection piece or the outlet. The fluidic isolation of the collecting container and the hand tool from each other can also be achieved by means of a nozzle cover of the collecting container and / or an optional outlet closure provided at the outlet. The nozzle cover and / or the optional outlet closure are in a closed position, i.e., the nozzle cover and / or the optional outlet closure fluidically close the connection piece or the outlet.In this way, when the collection container is coupled to the motor-driven hand tool, workpiece particles contained in the collection container are prevented from leaving the container in an undesirable manner. This can be useful, for example, in a situation where the collection container is transported while coupled to the motor-driven hand tool. Unwanted contamination during transport is thus reliably avoided.

[0065] Furthermore, the effects and advantages already explained in connection with the collecting container according to the invention and the assembly according to the invention also apply to the hand tool according to the invention, and vice versa. Likewise, the effects and advantages mentioned in connection with one or more of the methods according to the invention also apply to the structural aspects of the invention, i.e., to the collecting container according to the invention, the assembly according to the invention, and the hand tool according to the invention, and vice versa.

[0096] Figure 33 shows a variant of the collecting container from Figure 32.

[0097] Figure 1 shows a hand tool system 10.

[0098] The hand tool system 10 includes a storage container 12 and an assembly 14 having a motor-driven hand tool 16 and a collecting container 18 for workpiece particles.

[0099] In this example, the motor-driven hand tool 16 is a hand-held circular saw. However, this is purely exemplary.

[0100] The collecting container 18 is fluidically coupled to the hand tool 16, so that when working with the hand tool 16, an air-workpiece particle mixture can be introduced from the hand tool 16 into the collecting container 18. For this purpose, the collecting container 18 has a connecting piece 20, which forms an inlet opening 21, and a flexible container body 22, in which a certain amount of workpiece particles can be accommodated.

[0101] The connecting piece 20 is designed to be coupled to the hand tool 16 at its free end 24. At its opposite end, the connecting piece 20 opens into the container body 22.

[0102] The container body 22 comprises a supporting structure 26 constructed from a plurality of rigid struts 28 connected to one another via joints 30. The struts 28 and joints 30 form a folding mechanism 31, which will be explained below.

[0103] Furthermore, the container body 22 comprises an outer skin 32, which is formed as a covering 34 enclosing the support structure 26. It is noted that in the illustrations of Figures 1, 2, 5, and 6, the outer skin 32 is not shown for reasons of better visibility of the support structure 26.

[0104] The container body 22 assumes a transport position in Figures 1 and 2.

[0105] Furthermore, in the illustration according to Figure 1, the assembly 14 is arranged inside the storage container 12. A lid of the storage container 12 is not shown. It should be noted that, particularly in the illustration according to Figure 1, i.e., in a situation in which the assembly is arranged inside the storage container 12, the collecting container 18 is fluidically coupled to the hand tool 16. This is made possible by the compactness of the transport position.

[0106] A main extension 36 of the container body 22, i.e., the direction of the relatively largest length dimension of the container body 22, runs transversely to a main flow direction 38. In this context, the main flow direction 38 runs from an outer skin surface supporting the connecting piece 20 toward an opposite outer skin surface. It is understood that the main flow direction 38 is defined independently of whether or not an air-workpiece particle mixture actually flows from the hand tool 16 into the collecting container 18.

[0107] Furthermore, a height 42 of the container body 22 in the transport position is at most as large as a height 46 of the hand tool 16 defined vertically on a support plate 44 of the hand tool 16. In other words, a height 42 of the container body 22 in the transport position does not exceed the height 46 of the hand tool 16.

[0108] In addition, a length 48 of the container body 22 along a longitudinal direction 50 of the hand tool 16 amounts to a maximum of 50% of a length 52 of the support plate 44 when the container body 22 is in the transport position. In the example shown, the length 48 of the container body 22 is approximately 20% of the length 52 of the support plate 44.

[0109] Furthermore, a width overhang 54 of the container body 22 over a width 56 of the support plate 44 in the transport position amounts to approximately 40% of the width 56 of the support plate 44.

[0110] Figures 3 to 6 show the collecting container 18 according to the first embodiment in more detail. Figures 4 and 6 each show the transport position of the container body 22. Figures 3 and 5 show an operating position of the container body 22, which will be explained below.

[0111] In the illustrated embodiment, the support structure 26 is polygonal in a lateral view with respect to the main flow direction 34. In this context, the joints 30 form the polygon corners of the polygon shape, and the struts 28 form the polygon edges.

[0112] In the present case, the polygon has five polygon corners. In the transport position, one polygon corner, i.e., a joint 30, is accommodated between two polygon edges, i.e., between two struts 28, forming a concave outer peripheral section.

[0113] As a result, in the transport position, an outer skin section, ie a section of the outer skin 32, is folded into an interior of the container body 22.

[0114] By means of the folding mechanism 31, the container body 22 can be transferred into the working position, which is shown in Figures 3 and 5. In the working position, the container body 22 extends along the main flow direction 38. This means that a largest outer dimension of the container body 22 is oriented in the same direction as the main flow direction 38.

[0115] In the working position, the outer skin 32 encloses a first volume VI, which is much larger than a second volume V2 that encloses the outer skin 32 in the transport position. Thus, in the working position, a comparatively large quantity of workpiece particles can be accommodated inside the container body 22.

[0116] In the working position, the collecting container 18 has at least a first outer skin length dimension Lmax, which has a greatest length compared to the other outer skin length dimensions of the collecting container 18.

[0117] In the illustrated embodiment, the first outer skin length dimension Lmax is formed by a region of the outer skin 32 which rests on one of the struts 28.

[0118] The first outer skin length dimension Lmax corresponds to the length of the longest strut 28 of the collecting container 18.

[0119] The fact that in the working position, the first volume V1 enclosed by the outer skin 32 is much larger than the second volume V2 enclosed in the transport position, while at the same time the container body 22 is extremely compact in the transport position, is due to the fact that the first outer skin length dimension Lmax defines a maximum length of the container body in the transport position. In other words, the first outer skin length dimension Lmax determines the maximum external dimension of the container body 22 in the transport position.

[0120] It is understood that the container body 22 can also be transferred from the working position back into the transport position by means of the folding mechanism 31. In other words, the container body 22 can optionally assume either the transport position or the working position by using the folding mechanism 31.

[0121] In addition, the outer skin 32 comprises at least one elastically deformable outer skin section 58.

[0122] The folding mechanism 31 is configured such that the elastically deformable outer skin section 58 is maximally elastically stretched in an intermediate position which the container body 22 assumes when it is transferred from the transport position to the working position and vice versa.

[0123] As a result, the container body 22 can be held mechanically stable in the working position and in the transport position by means of the elastically deformable outer skin section 58. The intermediate position is mechanically unstable.

[0124] Figures 7, 8, and 9 show the assembly 14, with the collecting container 18 designed according to a second embodiment. Only the differences from the first embodiment will be explained below. Identical or corresponding components are provided with the same reference numerals.

[0125] As before, the support structure 26 is polygonal in a lateral view with respect to the main flow direction 34, with the joints 30 again forming the polygon corners of the polygon shape and the struts 28 again forming the polygon edges. However, in this case, the polygon has only four polygon corners.

[0126] A further difference is that the main extension 36 of the container body 22 in the transport position (see Figure 9) no longer runs transversely, but at an angle of approximately 30 degrees to the main flow direction 38.

[0127] This results in the situation that the container body 22 in the transport position has no width overhang beyond the width 56 of the support plate 44.

[0128] The length 48 of the container body 22 along the longitudinal direction 50 of the hand tool 16 is now approximately 70% of a length 52 of the support plate 44 when the container body 22 is in the transport position.

[0129] Furthermore, reference can be made to the explanations regarding the collecting container 18 according to the first embodiment.

[0130] Figures 10 and 11 show the assembly 14, with the collecting container 18 designed according to a third embodiment. Only the differences from the previously mentioned embodiments will be explained below. Identical or corresponding components are provided with the same reference numerals.

[0131] In this embodiment, the struts 28 and the joints 30 form a cross rod 60. In the working position (see Figure 10), the central regions of struts assigned to each other in pairs thus overlap in a cross-like manner.

[0132] In the transport position (see Figure 11), the paired struts are essentially placed on top of each other.

[0133] In this context, the first outer skin length dimension Lmax is formed by a region of the outer skin 32 that rests on one of the cross-shaped struts 28. In other words, the first outer skin length dimension Lmax again corresponds to the length of the longest strut 28.

[0134] In contrast to the aforementioned embodiments, in the third embodiment the outer skin as a whole is elastically deformable.

[0135] The width overhang in the transport position of the container body now amounts to approximately 15%.

[0136] The length 48 of the container body 22 along the longitudinal direction 50 of the hand tool 16 is now approximately 40% of a length 52 of the support plate 44 when the container body 22 is in the transport position.

[0137] Figures 12 and 13 show the assembly 14, with the collecting container 18 constructed according to a fourth embodiment. Only the differences from the previously mentioned embodiments will be explained below. Identical or corresponding components are provided with the same reference numerals.

[0138] In this embodiment, the struts 28 are each C-shaped.

[0139] They each have a joint 30 at the ends of the C-shape, via which the struts 28 are connected to one another in an articulated manner.

[0140] In the illustrated embodiment, all joints 30 have the same joint axis. The struts 28 can thus be rotated relative to each other in a fan-like manner and can thus be adjusted between the working position, in which the struts 28 are fanned out (see Figure 12), and the transport position, in which the struts 28 are stacked on top of each other (see Figure 13).

[0141] In this context, the first outer skin length dimension Lmax is formed by the arc height of the C-shaped struts 28. In contrast to the aforementioned embodiments, in the fourth embodiment, the outer skin 32 can be designed entirely without an elastic section. Thus, the outer skin as a whole is not elastically deformable.

[0142] The width overhang in the transport position of the container body now amounts to approximately 15%.

[0143] The length 48 of the container body 22 along the longitudinal direction 50 of the hand tool 16 is now approximately 40% of a length 52 of the support plate 44 when the container body 22 is in the transport position.

[0144] Figures 14 and 15 show a fifth embodiment of the collecting container 18. The collecting container 18 according to the fifth embodiment is a variant of the collecting container 18 according to the second embodiment (see Figures 7 to 9). Therefore, only the differences from the second embodiment will be explained below. Identical or corresponding components are provided with the same reference numerals.

[0145] In the collecting container 18 according to the fifth embodiment, the outer skin 32 has a serrated section 62 in the working position. This serves to enlarge the surface area of ​​the outer skin 32, while at the same time allowing the outer dimensions of the container body 22 to be kept the same as in a collecting container 18 with an outer skin 32 without the serrated section. This can improve the filtering function of the outer skin 32.

[0146] The serrated section 62 is formed by two of the struts 28 of the support structure 26 being serrated (see Figure 15). The serrated struts 28 are additionally provided with the reference numeral 64a and the reference numeral 64b, respectively.

[0147] The points of the serrated struts 64a, 64b are arranged such that, when viewed along the main flow direction 38, the circumference of the container body 22 remains constant along the main flow direction 38. This is achieved by the arrangement of the points of the serrated struts 64a, 64b. For better understanding, an imaginary zero line NI of the points is drawn in Figure 15 for the serrated strut 64a. An imaginary zero line N2 is drawn for the serrated strut 64b.

[0148] The zero lines NI, N2 correspond to the course of a straight, ie non-serrated strut, which could be used instead of the serrated struts 64a, 64b.

[0149] In addition, several exemplary circumferences 66a, 66b, 66c are illustrated in Figure 15.

[0150] The points of the struts 64a, 64b, ie, the corresponding peaks and valleys, extend evenly on both sides of the respective zero line N1, N2. Furthermore, the points of the struts 64a, 64b each extend in a single plane.

[0151] However, this plane is inclined relative to the side surfaces of the collecting container 18 defined by the respective struts 64a, 64b. More precisely, the planes in which the prongs of the struts 64a, 64b extend are inclined relative to the side surfaces of the collecting container 18 defined by the respective struts 64a, 64b such that the plane in which the prongs extend forms the same angle with each of these planes.

[0152] Thus, the serrated portion 62 extends over the side surface shown at the front in Figures 14 and 15, the side surface shown at the rear in Figures 14 and 15, and the side surface shown at the top in Figures 14 and 15.

[0153] Due to the inclination of the planes in which the points of the struts 64a, 64b extend, the corresponding peaks and valleys of the points compensate for each other such that the circumference of the container body 22 remains constant along the main flow direction 38. The exemplary circumferences 66a, 66b, 66c in Figure 15 are therefore equal. Consequently, the outer skin 32 can be formed without an elastic section. Furthermore, the outer skin 32, especially when unfolded, has a comparatively simple geometry.

[0154] In the embodiment according to Figures 14 and 15, the outer skin 32 is made from a continuous piece of material, ie not composed of several parts.

[0155] Figure 16 shows a sixth embodiment of the collecting container 18. The collecting container 18 according to the sixth embodiment is a variant of the collecting container 18 according to the fifth embodiment (see Figures 14 and 15). Therefore, only the differences from the fifth embodiment will be explained below. Identical or corresponding components are provided with the same reference numerals.

[0156] Again, for a better understanding of the serrated strut 64a, an imaginary zero line NI of the serrations is drawn.

[0157] In addition, several exemplary circumferences 66a, 66b, 66c are again illustrated in Figure 16.

[0158] In the sixth embodiment, the support structure 26 comprises only a single serrated strut 64a.

[0159] As before, the points of strut 64a, ie, the corresponding peaks and valleys, extend evenly on both sides of the zero line NI. Furthermore, the points of strut 64a extend in one plane.

[0160] As already explained in connection with Figures 14 and 15, the plane in which the prongs extend is inclined relative to the side surfaces of the collecting container 18 defined by the 64a, with the plane in which the prongs extend forming the same angle with each of these side surfaces. The effect of increasing the surface area while maintaining the same circumference of the outer skin 32 is also achieved in this way.

[0161] It is understood, however, that in the example of Figure 16, the circumference in general and in particular the exemplary circumferences 66a, 66b, 66c, are constant in amount when viewed transversely to the main flow direction 38.

[0162] In the fifth and sixth embodiments (see Figures 14 to 16), corrugated struts can also be used instead of serrated struts 64a, 64b. This ensures that the outer skin 32 of the collecting container 18 has a corrugated section. Corrugated struts differ from serrated struts in that they do not have any straight sections, at least in the corrugation area. The above explanations apply equally to collecting containers 18 whose outer skin 32 has a corrugated section.

[0163] Figures 17 to 19 show in detail a portion of the assembly 14 from Figures 1 to 6, in which the collecting container 18 according to the first embodiment is coupled to the motor-driven hand tool 16. This means that the collecting container 18 is fluidly coupled to the hand tool 16 via the connecting piece 20, so that an air-workpiece particle mixture can be introduced from the hand tool 16 into the collecting container 18.

[0164] In the illustrated embodiment, the connecting piece 20 is provided on a dimensionally stable section 68 of the outer skin 32. As a result, the collecting container 18, or more precisely the container body 22, has a comparatively high degree of dimensional stability in the region of the connecting piece 20, so that the collecting container 18 can be easily handled for coupling to and detaching from the hand tool 16.

[0165] The connecting piece 20 is also dimensionally stable.

[0166] Furthermore, the dimensionally stable section 68 and the connecting piece 20 are manufactured as a single piece. The free end 24 of the connecting piece 20 protrudes from the container body 22. Furthermore, a bearing block 72 is positioned on the outer circumference 70 of the connecting piece 20, via which a piece cover 74 is rotatably mounted on the connecting piece 20.

[0167] An associated rotation axis 76, about which the nozzle cover 74 is rotatable, runs transversely to a longitudinal extension direction 78 of the connecting nozzle 20.

[0168] The rotation axis 76 is spaced from the outer circumference 70 of the connecting piece 20. The distance between the rotation axis 76 and the outer circumference 70 is therefore greater than zero.

[0169] Thus, the nozzle cover 74 can optionally close (see Figure 20) or release (see Figures 17 to 19) the connection nozzle 20 at the free end by corresponding rotation about the rotation axis 76.

[0170] The collecting container 18 can only be coupled to the hand tool 16 if the nozzle cover 74 releases the connection nozzle 20.

[0171] The coupled state is characterized in that a connection piece-side sealing section 80, which is positioned on an inner circumference 82 of the connection piece 20 adjacent to the free end 24, is in contact with a hand tool-side sealing section 84 (see Figures 18 and 19).

[0172] When the nozzle cover 74 closes the connection nozzle 20, ie when the nozzle cover 74 is in the closed position, a cover-side sealing section 86 lies at least partially opposite or on the connection nozzle-side sealing section 80 (see Figure 20).

[0173] In this case, a sealing element 88 in the form of a sealing lip is arranged on the connection piece-side sealing section 80.

[0174] A sealing element 90 in the form of a sealing lip is also provided on the hand tool-side sealing section 84. The nozzle cover is preloaded into the closed position by a spring device 92.

[0175] The nozzle cover 74 is shown in isolation in Figures 22 and 23.

[0176] The nozzle cover 74 has a closure portion 94 which is designed to selectively close the free end 24 of the connection nozzle 20.

[0177] Furthermore, the nozzle cover 74 has an actuating portion 96 comprising an actuating surface 98 designed to be subjected to a compressive force by a human finger in order to move the nozzle cover 74 from the closed position to the open position, counter to the force exerted by the spring device 92. The actuating portion 96 is thus designed for manually releasing the free end 24 of the connecting nozzle 20.

[0178] The nozzle cover 74 is designed as a single, continuous component. Accordingly, the closure section 94 and the actuating section 96 are also designed as a single piece but separate from each other.

[0179] The closure section 94 and the actuating section 96 enclose an obtuse angle 100 in a plane of rotation, ie viewed along the axis of rotation 76.

[0180] In addition, the locking portion 94 and the actuating portion 96 are positioned on opposite sides of the rotation axis 76.

[0181] In other words, the closure portion 94 and the actuating portion 96 are spaced apart from each other.

[0182] Furthermore, a retaining rib 102 with a mounting bevel 104 is formed on the closure section 94.

[0183] The retaining rib 102 serves to lock the collecting container 18 in a position coupled to the motor-driven hand tool 16 (see Figures 18 and 19). The retaining rib 102 is positioned on a side of the closure section 94 facing the connecting piece 20. Accordingly, in the closed position, the retaining rib 102 projects into the interior of the connecting piece 20.

[0184] A recess 106 is also provided on the closure section 94.

[0185] The recess 106 serves to receive a portion of the hand tool 16 in a position of the collecting container 18 coupled to the motor-driven hand tool 16 (see Figure 18).

[0186] The recess 106 is also positioned on a side of the closure section 84 facing the connecting piece 20.

[0187] The retaining rib 102 is closer to the rotation axis 76 than the recess 106.

[0188] An outlet 108 of the motor-driven hand tool 16, which is part of the assembly 14, can be seen in detail in Figure 21.

[0189] The outlet 108 serves to discharge the air-workpiece particle mixture from the hand tool 16. A retaining bead 112 for coupling the collecting container 18 for workpiece particles is arranged on an outer circumference 110 of the outlet 108.

[0190] The retaining bead 112 is also provided with a mounting bevel 114.

[0191] Furthermore, the hand tool 16 has a contact area 116. This is designed to be contacted by the nozzle cover when the collecting container 18 is coupled to the hand tool 16.

[0192] The nozzle cover 74 can thus lock the collecting container 18 to the hand tool 16 in a situation in which the collecting container 18 is coupled to the hand tool 16. For this purpose, the retaining rib 102 of the nozzle cover 74 engages behind the retaining bead 112 of the hand tool 16. Furthermore, the nozzle cover 74 contacts the contact area 116 of the hand tool 16, at least in sections, in the area of ​​the recess 106 (see Figures 17 and 18).

[0193] Due to the fact that the nozzle cover 74 is pre-tensioned into its closed position by means of the spring device 92, the locked state of the collecting container 18 on the hand tool 16 can only be released by the application of force.

[0194] This can be done by applying an actuating pressure force to the actuating section 96.

[0195] By means of such an actuation, the actuating section 96 can be moved closer to the outer circumference 70 of the connecting piece in a view along the rotation axis 76, so that the closure section lifts off from the hand tool 16.

[0196] In this way, the nozzle cover 74 can be brought into a release position in which it releases the connecting nozzle 20 at the free end 24 and encloses an angle 118 of more than 90° with a connection cross-section of the connecting nozzle 20 (see Figure 19).

[0197] In such a position of the nozzle cover 74, the connecting nozzle 20 can be pulled off the outlet 108 or pushed onto the outlet 108 with little resistance. In other words, in such a position of the nozzle cover 74, the collecting container 18 can be easily coupled to the hand tool 16 and just as easily uncoupled from it.

[0198] If the nozzle cover 74 is not actuated in a state in which the collecting container 18 is not connected to the hand tool, it closes the connecting nozzle 20 (see Figure 20). In this position, the actuating section 96 is located on a side of the rotation axis 76 facing away from the connecting nozzle 20.

[0199] To release the free end 24 of the connecting piece 20, the piece cover 74 must now be actuated such that the actuating section 96 is moved to a side of the rotation axis 76 facing the connecting piece 20 (see Figure 19). The piece cover 74 and the associated devices of the collecting container 18 and the motor-driven hand tool 16 were explained above using the collecting container 18 according to the first embodiment (see Figures 1 to 6). However, it is understood that the explanations regarding the piece cover 74 and the associated devices of the collecting container 18 and the motor-driven hand tool 16 apply equally to the other embodiments of the collecting container 18.

[0200] As can be seen from Figure 24, the dimensionally stable portion 68 of the outer skin 32 further comprises an emptying opening 120.

[0201] The emptying opening 120 serves to remove workpiece particles from the container body 22, e.g., when machining of a workpiece is completed and the container body 22 is to be returned to the transport position, or when a limit filling level of the container body 22 with workpiece particles is reached during machining of the workpiece.

[0202] The collecting container 18 further comprises a closure means 122 which can be fastened to the container body 22 at least in a closed position, so that the emptying opening 120 can be selectively closed by means of the closure means 122.

[0203] In the illustrated embodiment, the closure means 122 is designed as a dimensionally stable lid 124.

[0204] The section of the dimensionally stable section 68 of the outer skin 32 surrounding the emptying opening 120 further forms a dimensionally stable frame 126 which delimits the emptying opening 120.

[0205] The closure means 122, more precisely the lid 124, is pivotally attached to the container body 22, more precisely to the dimensionally stable frame 126, via a hinge 128.

[0206] In the present case, the connecting piece 20 is also arranged on the closure means 122, i.e., on the cover 124. The connecting piece 20 and the cover 124 are formed as a single piece. Thus, the inlet opening 21 and the discharge opening 120 are positioned on the same outer skin surface of the outer skin 32.

[0207] The collecting container 18 further comprises a locking unit 130, shown only schematically in Figure 24, by means of which the closure means 122 can be locked in a closed position on the frame 126.

[0208] The locking unit 130 comprises a first actuating surface 130a and a second actuating surface 130b, via which the locking unit 130 can be actuated.

[0209] The first actuating surface 130a and the second actuating surface 130b are spaced apart by a maximum of 15 cm. Thus, the first actuating surface 130a and the second actuating surface 130b can be simultaneously grasped by different fingers of a single human hand. In other words, the locking unit 130 can be actuated with a single human hand.

[0210] Figures 24 and 25 show a collecting container 18 according to a seventh embodiment. The container body 22 is shown only in sections in each case. More precisely, only a dimensionally stable section 68 of the outer skin 32, on which the connecting piece 20 is arranged, is shown.

[0211] As before, the dimensionally stable section 68 comprises the emptying opening 120, which can be optionally closed by means of a closure means 122 designed as a dimensionally stable cover 124.

[0212] The sections of the dimensionally stable section 68 of the outer skin 32 surrounding the emptying opening 120 further form a dimensionally stable frame 126 which delimits the emptying opening 120.

[0213] The closure means 122, more precisely the lid 124, is pivotally attached to the container body 22, more precisely to the dimensionally stable frame 126, via a hinge 128. The closure means 122 can be locked in a closed position on the frame 126 by means of a locking unit 130.

[0214] Figure 24 represents a perspective view along the direction XXIV in Figure 25 and Figure 25 represents a perspective view along the direction XXV in Figure 24.

[0215] The collecting container 18 is shown in a state in which it is decoupled from the motor-driven hand tool 16.

[0216] As before, the following only deals with the differences compared to the embodiments already explained, in particular compared to the embodiment explained with reference to Figures 17 to 23.

[0217] The differences concern the nozzle cover 74.

[0218] In the seventh embodiment of the collecting container 18, the nozzle cover 74 is rotatably mounted on the outer skin 32, more precisely on the dimensionally stable section 68 of the outer skin 32.

[0219] In the illustrated embodiment, the nozzle cover 74 is rotatably mounted on the cover 124.

[0220] The bearing is arranged outside the connection piece 20.

[0221] Furthermore, the bearing is positioned on an outer side of the outer skin 32.

[0222] The associated axis of rotation 76, about which the nozzle cover 74 is rotatable, runs transversely to a longitudinal extension direction 78 of the connecting nozzle 20. In addition, the axis of rotation 76 is oriented substantially horizontally in a use position of the collecting container 18.

[0223] Thus, the nozzle cover 74 can close and release the connecting nozzle 20 by corresponding rotation about the rotation axis 76. In Figures 24 and 25, the nozzle cover 74 is shown in an intermediate position, i.e., neither fully open nor fully closed, for the sake of simplicity. As before, the nozzle cover 74 comprises an actuating section 96 and a closing section 94.

[0224] The closure section 94 is plate-shaped and shaped such that it can close the connection piece 20 at one end on the container body side.

[0225] For this purpose, an end of the closure section facing away from the actuating section 96 is rounded in such a way that it can lie opposite an inner circumference of the connecting piece 20 in the closed position.

[0226] The actuating portion 96 is designed such that, in the release position of the nozzle cover 74, it can conform to an outer circumference of the connecting nozzle 20. For this purpose, the actuating portion 96 is curved, with a radius of curvature essentially corresponding to a radius of the outer circumference of the connecting nozzle 20.

[0227] At the end of the actuating section 96 facing away from the closure section 94, an actuating collar 158 is also provided, which protrudes from the other sections of the nozzle cover 74.

[0228] Furthermore, the nozzle cover 74 includes an indicator 160 that indicates its release position. In the illustrated embodiment, the word "work" is applied to the actuating portion 96 for this purpose. This is positioned such that it is only clearly visible when the nozzle cover 74 is in the release position. In the present case, the word "work" is applied to a convex outer side of the curved portion of the actuating portion 96. It can thus be clearly seen by a user when the actuating portion 96 is pressed against the connecting nozzle 20.

[0229] The nozzle cover also includes an indicator 162 that indicates its closed position. In the illustrated embodiment, the word "no work" is applied to the actuating collar of the actuating section 96. This word is positioned such that it is only clearly visible when the nozzle cover 74 is in the closed position. In the present case, the word "no work" is applied to a side of the actuating collar facing away from the closure section 94. It can thus be clearly seen by a user when the nozzle cover 74 closes the connecting nozzle 20.

[0230] In the embodiment of Figures 24 and 25, the closure section 94 is further arranged in an interior of the container body 22, ie within an area surrounded by the outer skin 32, and the actuating section 96 is arranged outside the container body 22. To make this possible, the outer skin 32 has a passage opening 164 through which the nozzle cover 74 extends.

[0231] In the embodiment of Figures 24 and 25, the passage opening 164 is formed on the cover 124.

[0232] As before, the nozzle cover 74 is designed as a single, coherent component. Accordingly, the closure section 94 and the actuating section 96 are also designed as a single piece but separate from each other.

[0233] The closure section 94 and the actuating section 96 enclose an angle 100 of substantially 180 degrees in a rotational plane, ie viewed along the rotational axis 76.

[0234] In contrast to the embodiment of Figures 17 to 23, the nozzle cover 74 of the embodiment of Figures 24 and 25 does not have a retaining rib. In the embodiment according to Figures 24 and 25, the collecting container can be coupled to the outlet 108 of the motor-driven hand tool 16 via a coupling ring 166 provided at the free end 24 of the connecting nozzle 20.

[0235] Figures 26 and 27 show a collecting container 18 according to an eighth embodiment. The container body 22 is again shown only in sections. The collecting container 18 is shown in a state in which it is decoupled from the motor-driven hand tool 16.

[0236] Figure 26 represents a perspective view along the direction XXVI in Figure 27 and Figure 27 represents a perspective view along the direction XXVII in Figure 26. However, in Figure 26 the nozzle cover 74 assumes a closed position and in Figure 27 a released position.

[0237] As before, in the following only the differences compared to the embodiments already explained, in particular compared to the embodiment explained with reference to Figures 24 and 25, will be discussed.

[0238] The differences concern the nozzle cover 74.

[0239] In the eighth embodiment of the collecting container 18, the nozzle cover 74 is again rotatably mounted on the outer skin 32, more precisely on the dimensionally stable section 68 of the outer skin 32. However, the mounting is now positioned on an inner side of the outer skin 32.

[0240] The associated axis of rotation 76, about which the nozzle cover 74 is rotatable, runs transversely to a longitudinal extension direction 78 of the connecting nozzle 20. In addition, the axis of rotation 76 is oriented substantially horizontally in a use position of the collecting container 18.

[0241] Thus, the nozzle cover 74 can close and release the connection nozzle 20 by corresponding rotation about the rotation axis 76.

[0242] As before, the nozzle cover 74 comprises an actuating section 96 and a closing section 94.

[0243] The closure section 94 is again plate-shaped, so that it can close the connecting piece 20 at one end on the container body side. The actuating section 96 is now connected to the closure section 94 via an arcuate actuating arm 168. A center point of the arcuate shape of the actuating arm 168 lies on the rotation axis 76.

[0244] The actuating portion 96 is designed such that, in the release position of the nozzle cover 74, it can nestle against an outer side of the outer skin 32. More precisely, in the release position, the actuating portion 96 rests against the outer side of the outer skin 32 (see Figure 27).

[0245] On the actuating section 96, an actuating collar 158 is also provided, which protrudes from the other sections of the actuating section 96.

[0246] Furthermore, the nozzle cover 74 includes an indicator 160 that indicates its release position. In the illustrated embodiment, the word "work" is applied to the actuating collar 158 for this purpose. This is positioned such that it is clearly visible only when the nozzle cover 74 is in the release position.

[0247] The nozzle cover also includes an indicator 162 that indicates its closed position. In the illustrated embodiment, the word "travel" is applied to the actuating portion 96. This is positioned such that it is only clearly visible when the nozzle cover 74 is in the closed position.

[0248] In the embodiment of Figures 26 and 27, the closure portion 94 is further arranged in an interior of the container body 22, ie within an area surrounded by the outer skin 32, and the actuating portion 96 is arranged outside the container body 22. To make this possible, the outer skin 32 has a passage opening 164 through which the actuating arm 168 extends.

[0249] In the embodiment of Figures 26 and 27, the passage opening 164 is formed on the cover 124. - M -

[0250] As in the embodiment of Figures 24 and 25, the nozzle cover 74 of the embodiment of Figures 26 and 27 does not have a retaining rib. In the embodiment according to Figures 26 and 27, the collecting container 18 can be coupled to the outlet 108 of the motor-driven hand tool 16 via a coupling ring 166 provided at the free end 24 of the connecting nozzle 20. However, for reasons of clarity, the coupling ring 166 is not shown in Figures 26 and 27.

[0251] Figures 28 and 29 show a collecting container 18 according to a ninth embodiment. The container body 22 is again shown only in sections.

[0252] The collecting container 18 is shown in a state in which it is decoupled from the motor-driven hand tool 16.

[0253] Figure 28 represents a perspective view along the direction XXVIII in Figure 29 and Figure 29 represents a perspective view along the direction XXIX in Figure 28.

[0254] In Figures 28 and 29, the nozzle cover 74 is shown in an intermediate position, ie neither fully open nor fully closed, for reasons of ease of explanation.

[0255] In the following, as before, only the differences compared to the embodiments already explained, in particular compared to the embodiments explained with reference to Figures 24 and 25 and Figures 26 and 27, will be discussed.

[0256] The differences concern the nozzle cover 74.

[0257] In the ninth embodiment of the collecting container 18, the nozzle cover 74 is again rotatably mounted on the outer skin 32, more precisely on the dimensionally stable section 68 of the outer skin 32. Again, the mounting is positioned on an inner side of the outer skin 32. In contrast to the embodiment of Figures 26 and 27, however, the nozzle cover 74 is now mounted on the outer skin 32 via a bearing block 170 that protrudes from the outer skin 32 toward an interior of the container body 22.

[0258] The associated axis of rotation 76, about which the nozzle cover 74 is rotatable, runs transversely to a longitudinal extension direction 78 of the connecting nozzle 20. In addition, the axis of rotation 76 is oriented substantially vertically in a use position of the collecting container 18.

[0259] Thus, the nozzle cover 74 can close and release the connection nozzle 20 by corresponding rotation about the rotation axis 76.

[0260] As before, the nozzle cover 74 comprises an actuating section 96 and a closing section 94.

[0261] The closure section 94 is again plate-shaped so that it can close the connection piece 20 at one end on the container body side.

[0262] The actuating section 96 is rod-shaped and is connected to the closure section 94 via an actuating arm 168 designed as a straight torsion bar. Such an actuating arm 168 can also be referred to as a shaft. A central axis of the actuating arm 168 coincides with the rotational axis 76.

[0263] In the embodiment of Figures 28 and 29, the closure section 94 is again arranged in an interior of the container body 22, ie within an area surrounded by the outer skin 32, and the actuating section 96 is arranged outside the container body 22. To make this possible, the outer skin 32 has a passage opening 164 through which the actuating arm 168 extends.

[0264] In the embodiment of Figures 24 and 25, the passage opening 164 is formed on the cover 124. As in the embodiment of Figures 24 and 25, the nozzle cover 74 of the embodiment of Figures 28 and 29 does not have a retaining rib. In the embodiment according to Figures 28 and 29, the collecting container 18 can be coupled to the outlet 108 of the motor-driven hand tool 16 via a coupling ring 166 provided at the free end 24 of the connecting nozzle 20.

[0265] The collecting container 18 according to the embodiments shown in Figures 24 to 29 further differs from the collecting container 18 explained with reference to Figures 17 to 23 in that in the collecting container 18 according to the embodiments shown in Figures 24 to 29, the nozzle cover 74 can be transferred into the closed position, i.e., can close the connecting nozzle 20, while the collecting container 18 is coupled to the motor-driven hand tool 16. In this way, in a state in which the collecting container 18 is coupled to the motor-driven hand tool 16, workpiece particles received in the collecting container 18 are prevented from undesirably leaving the collecting container 18. This may be useful, for example, in a situation where the collection container 18 is transported while coupled to the motor-driven hand tool 16.

[0266] Using a collecting container 18 according to an embodiment shown in Figures 24 to 29, a method for coupling a collecting container 18 for workpiece particles and a motor-driven hand tool 16 can also be carried out.

[0267] At the beginning of the process, the nozzle cover 74 is in the closed position, ie the connecting nozzle 20 is closed by means of the nozzle cover 74.

[0268] Then, in a first step, the connecting piece 20 and the hand tool 16 are connected. The connecting piece 20 remains closed by the piece cover 74.

[0269] In a subsequent second step, the connecting piece 20 is released by moving the piece cover 74 from a closed position to a released position. Furthermore, a method for decoupling a collecting container 18 for workpiece particles and a motor-driven hand tool 16 can be carried out using a collecting container 18 according to an embodiment shown in Figures 24 to 29.

[0270] At the start of the decoupling process, the nozzle cover 74 is in the release position, ie the connection nozzle 20 is released or open.

[0271] It is then closed by means of the nozzle cover 74 in a first step of the process for decoupling the connecting nozzles 20.

[0272] Subsequently, in a second step of the decoupling process, the connecting piece 20 and the hand tool 16 are separated.

[0273] Figure 30 shows the hand tool 16 in a machining position. In Figure 30, a machining zone 132 is located below the hand tool 16.

[0274] The collecting container 18 is coupled to the hand tool 16. Consequently, in a use position of the collecting container 18, the hinge 128 is positioned on a side of the connecting piece 20 facing away from the processing zone 132.

[0275] On the one hand, this has the effect that in the use position of the collecting container 18, ie in the position shown in Figure 30, the force of gravity acts in the closing direction on the closure means 122 and the container body 22.

[0276] Furthermore, in a use position of the collecting container 18, ie in the position shown in Figure 30, an emptying direction 134, which is perpendicular to an opening cross-section of the emptying opening 120 and, starting from an interior of the container body 22, points through the emptying opening 120, in the direction of the processing zone 132.

[0277] More specifically, in a situation in which the closure means 122 is in an open position, the emptying direction 134 has an extension component 136 pointing vertically in the direction of the processing zone 132. It is emphasized that the collecting container 18 is coupled to the hand tool 16 both in an open position of the closure means 122 and in a closed position of the closure means 122.

[0278] Figure 31 shows a variant of the embodiment of Figure 30. The discharge opening 120 is arranged on an outer skin surface of the outer skin 32, which is located laterally with respect to the main flow direction 38.

[0279] Figure 31 also shows the hand tool 16 in a machining position. Here, the machining zone 132 is again located below the hand tool 16.

[0280] The hinge 128 is now arranged on a side of the emptying opening 120 facing away from the connecting piece 20. Thus, when the closure means 122 is open, the emptying direction 134 again points toward the processing zone. In the variant shown in Figure 31, the emptying direction 134 is oriented vertically. It therefore only has component 136, which points vertically downward toward the processing zone 132.

[0281] Both with the collecting container 18 according to the variant from Figure 30 and with the collecting container according to the variant from Figure 31, a method for emptying a collecting container 18 of an assembly 14 with a motor-driven hand tool 16 and a collecting container 18 can be carried out.

[0282] In an initial state, the collecting container 18 is coupled to the hand tool 16, so that an air-workpiece particle mixture can be introduced from the hand tool 16 into the collecting container 18. This coupling remains intact throughout the entire process for emptying the collecting container 18.

[0283] In a first step, the closure means 122 is unlocked by actuating the locking unit 130. Subsequently, in the variant according to Figure 30, the section of the container body 22 of the collecting container 18 that supports the dimensionally stable frame 126 is tilted upward against the force of gravity relative to the hand tool 16 and the closure means 122. As already mentioned, the coupling between the collecting container 18 and the hand tool 18 is maintained.

[0284] Now, the component 136 of the emptying direction 134 points vertically downwards in the direction of the processing zone 132, so that workpiece particles can be easily removed from the interior of the container body 22.

[0285] For this purpose, the assembly 14 comprising the motor-driven hand tool 16 and the collecting container 18 can be held, for example, over a bucket or other suitable container. It is important that the hand tool 16 is held in the same position it assumes during use for material processing.

[0286] When a sufficient amount of workpiece particles has been removed from the interior of the container body 22, the section of the container body 22 that supports the dimensionally stable frame 126 is tilted downward again in the direction of gravity and the closure means 122 is locked to the frame 126 by means of the locking unit 130.

[0287] In the variant according to Figure 31, the closure means 126 is folded downwards supported by gravity.

[0288] Now the emptying direction 134 points vertically downwards in the direction of the processing zone 132, so that workpiece particles can be easily removed from the interior of the container body 22.

[0289] Once a sufficient quantity of workpiece particles has been removed from the interior of the container body 22, the closure means 126 is returned to its closed position against gravity and locked there to the frame 126 by means of the locking unit 130. It is again understood that the explanations of Figures 30 and 31 apply not only in connection with the first embodiment of the collecting container 18, but can be combined with all of the embodiments explained above.

[0290] Figure 32 shows the collecting container 18 according to the first embodiment from Figures 3 and 4 in another perspective view.

[0291] Figure 32 shows that the outer skin 32 has a light-incidence section 138 that is translucent. In the illustrated embodiment, the light-incidence section is translucent but not transparent.

[0292] It is made of a white or light gray textile material that is dimensionally stable. The light-incidence section 138 thus contributes to the filtering effect of the outer skin 32.

[0293] In addition, light can fall into the interior of the container body via the light incidence section 138.

[0294] In addition, the outer skin 32 has a viewing window section 140.

[0295] This is made of an optically transparent, shape-stable plastic material. This material can also be referred to as plastic film.

[0296] In the illustrated embodiment, the viewing window section 140 is sewn to the remaining sections of the outer skin 32, ie it is connected to the remaining sections of the outer skin 32 via a sewing thread.

[0297] It is understood that in other embodiments, the viewing window portion 140 is alternatively or additionally connected to the remaining portions of the outer skin 32 by means of a weld seam, an adhesive seam or other suitable means.

[0298] The viewing window section 140 also has an antistatic section 142, which in this case is embodied as an electrically conductive coating. It is understood that the antistatic section may, but need not, fill the entire surface of the viewing window section 140.

[0299] The antistatic portion 142 is further electrically connected to an electrical connection contact 144 arranged on the connection piece 20.

[0300] Alternatively, the antistatic section 142 may comprise a material with hydrophilic properties, allowing an electrostatic charge to be transferred to humid room air by means of this material. In other words, when using a hydrophilic material, potential equalization can occur between the antistatic section and the humidity of the room air.

[0301] The electrical connection contact 144 is designed to enable electrical potential equalization between the antistatic section 142 and the hand tool 16.

[0302] In this way, an electrostatic charge of the viewing window section 140 is reliably avoided or at least reduced to such an extent that the function of the viewing window section 140 is not restricted.

[0303] In the present exemplary embodiment, both the viewing window section 140 and the light incidence section 138 are arranged on an outer skin surface of the outer skin 32 which is located laterally with respect to the main flow direction 38.

[0304] The light incidence section 138 is formed on a first outer skin surface 146 of the outer skin 32 and the viewing window section 140 is formed on a second outer skin surface 148 of the outer skin 32.

[0305] The first outer skin surface 146 and the second outer skin surface 148 adjoin one another at an outer skin edge 150. The light incidence section 148 and the viewing window section 140 thus delimit a transmitted light zone 152 that extends inside the container body 22.

[0306] The transmitted light zone 152 comprises at least one viewing axis 154 which connects at least one point of the light incidence section 138 with at least one point of the viewing window section 140 in a straight line.

[0307] Light can thus enter the interior of the container body 22 through the light incidence section 138. This allows a user of the collecting container 18 to visually determine the fill level of the collecting container 18 with high precision through the viewing window section 140.

[0308] Optionally, the viewing window section 140 is provided with a fill level scale 156.

[0309] It is understood that the same effects and advantages can also be achieved if the light incidence section 138 and the viewing window section 140 are formed on outer skin surfaces of the outer skin 32 that are at least partially opposite one another. This configuration also results in a straight line of sight that connects at least one point of the light incidence section 138 with at least one point of the viewing window section 140.

[0310] Figure 33 shows a further variant of the collecting container 18 according to the first embodiment from Figures 3 and 4.

[0311] In this variant, the closure means 122, designed as a lid 124, is made of a transparent, dimensionally stable plastic material. The lid 124 thus encompasses the light incidence section 138.

[0312] Thus, the light incidence section 138 and the connecting piece 20 are arranged on the same outer skin surface. The viewing window section 140 is implemented in the same way as in the embodiment according to Figure 32.

[0313] Since in the variant shown in Figure 33 both the light incidence section 138 and the viewing window section 140 are made of a transparent material, the function of the light incidence section 138 and the viewing window section 140 can also be reversed. In this context, the cover 124 includes the viewing window section 140.

[0314] It is again understood that the explanations regarding Figures 32 and 33 apply not only in connection with the first embodiment of the collecting container 18, but can be combined with all of the embodiments explained above. Furthermore, the nozzle cover 74 was always described above in several embodiments as a component that can selectively close or open the connecting nozzle 20. Alternatively or additionally, however, the nozzle cover 74 can be provided on the outlet 108 of the motor-driven hand tool, so that the outlet 108 can be selectively opened or closed by means of the nozzle cover 74. In such a case, the nozzle cover 74 can also be referred to as an outlet closure. The above explanations, in particular the statements regarding the nozzle cover 74 in Figures 17 to 29, apply accordingly to the outlet closure.
