Description

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

[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. The container body comprises a folding mechanism so that the container body can selectively assume a working position in which the outer skin encloses a first volume, and selectively assume a transport position in which the outer skin encloses a second volume. The second volume is smaller than the first volume.

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

[0004] Furthermore, the invention relates to a hand tool system with such an assembly and a storage container.

[0005] Such hand tool systems, assemblies, and collection containers 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 predetermined 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.

[0006] AS: TOP workpiece particles are retained in the collection container, so that material processing causes comparatively little contamination.

[0007] In order to collect the largest possible quantity of workpiece particles and thus only rarely have to empty the collection container, the largest possible volume of the container body in the working position is desirable. In other words, the initial volume should be large. Furthermore, the outer skin should have the largest possible surface area in the working position. This is beneficial for the filter function explained above. In addition, any air-workpiece particle mixture flowing into the collection container must be slowed down within the collection container. This can be achieved particularly effectively if one dimension of the container body along a corresponding main flow direction is as large as possible.

[0008] In contrast, the aim for the transport position is always to keep the container body as small as possible. In other words, the second volume should be as small as possible.

[0009] The working position and the transport position therefore result in contradictory requirements for the collection container.

[0010] The object of the invention is therefore to create a collection container that resolves or at least mitigates this conflict of requirements. The aim is to create a collection container that has a comparatively large volume in the working position and is as compact as possible in the transport position.

[0011] The problem is solved 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. The container body comprises a folding mechanism so that the container body can optionally assume a working position in which the outer skin encloses a first volume, and optionally assume 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 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 length 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 the outer skin length dimension that 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 largest outer skin length 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 therefore does not become any longer as a result of folding. This allows a good compromise to be achieved 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.

[0012] The fact that, in the collection container according to the invention, the first outer skin length dimension defines a greatest length of the container body in the transport position means in the present case that the first outer skin length dimension determines or establishes the greatest length of the container body in the transport position. In particular, the first outer skin length dimension alone defines the greatest length of the container body in the transport position. The first outer skin length dimension therefore alone determines the greatest length of the container body in the transport position or alone establishes the greatest length of the container body in the transport position. The greatest length of the container body in the transport position can essentially correspond to the first outer skin length dimension. The greatest length of the container body in the transport position and the first outer skin length dimension can therefore be essentially the same.Alternatively, the greatest length of the container body in the transport position and the first outer skin length dimension may be different, although the first outer skin length dimension always defines, i.e., determines or specifies, a greatest length of the container body in the transport position. In other words, the greatest length of the container body in the transport position is a function of the first outer skin length dimension or at least dependent on the first outer skin length dimension.

[0013] In one example, the container body in the working position has a filling volume that is greater than 0.8 liters.

[0014] Depending on the specific application, the workpiece particles are also referred to as dust, e.g. grinding dust, or chips, e.g. sawdust.

[0015] In one embodiment, the container body comprises a support structure formed from struts that are connected to one another in an articulated manner. The outer skin is then formed by a covering that encloses the support structure. Such a container body can be easily transferred from the working position to the transport position and vice versa. The container body is mechanically stable in both positions. Furthermore, a support structure formed from struts that are connected to one another in an articulated manner can be compactly folded up. In this context, the joints that connect the struts to one another form the folding mechanism. At least two struts can be C-shaped, at least in sections, and connected to one another in an articulated manner. Alternatively, the struts can form at least two strut assemblies, each of which is at least in sections C-shaped. In this case, the at least two struts that are at least in sections C-shaped orThe two strut assemblies, which are at least partially C-shaped, can be rotated in a fan-like manner relative to each other. Consequently, in the working position, the two C-shaped struts or the two C-shaped strut assemblies can be spanned in a fan-like manner to achieve a comparatively large volume of the container body. In the transport position, the two C-shaped struts or the two C-shaped strut assemblies can essentially be placed on top of each other, so that the container body is compact in the transport position.

[0016] In this context, both the C-shaped struts and the C-shaped strut assemblies each have joint elements at their ends. Within a C-shaped strut and within a C-shaped strut assembly, the joint elements arranged at each end share a common joint axis. In a container body comprising at least two C-shaped struts or at least two C-shaped strut assemblies, the joint axes of adjacent struts or strut assemblies are close to one another or coincide.

[0017] In another embodiment, the struts form a cross-bar assembly. Thus, at least two struts are rotatably attached to one another via their respective center sections. This allows the at least two struts to assume a relative position in the working position in which they intersect when viewed along the axis of rotation. In the transport position, the struts can be essentially placed on top of one another due to their rotatable attachment to one another. This makes it easy to achieve a large volume for the container body when it is in the working position and a small volume when the container body is in the transport position.

[0018] The support structure can also be polygonal in a lateral view with respect to a main flow direction. The main flow direction runs from an outer skin surface, which includes an inlet for the air-workpiece particle mixture, toward an opposite outer skin surface. A polygonal support structure allows a comparatively large volume to be spanned in the working position.

[0019] In this context, the polygonal shape can comprise four or five polygonal corners, each formed by articulated connections of struts. The articulated connections are components of the folding mechanism. The polygonal support structure can thus be folded from the working position to the transport position and vice versa.

[0020] In the transport position, it is possible for at least one polygon corner to be accommodated between two polygon edges, forming a concave outer peripheral section. This allows for an extremely compact transport position.

[0021] In one variant, at least one area of ​​the outer skin resting on one of the struts forms a first outer skin length dimension. The outer skin length dimension thus essentially corresponds to a length dimension of the strut on which the outer skin area rests. Since the first outer skin length dimension has the greatest length compared to the other outer skin length dimensions, the first outer skin length dimension corresponds to the length of the longest strut. In the transport position, the container body is folded so that this longest strut defines the total length of the container body.

[0022] The struts can be rigid, meaning they can only be moved relative to each other via joints. This allows the container body to be moved in a defined manner, especially from the transport position to the working position and vice versa.

[0023] In the transport position, at least one outer skin section can also be folded into the interior of the container body. In this way, the container body has a comparatively small volume and comparatively small external dimensions in the transport position. In other words, the container body is compact in the transport position. In the working position, the container body preferably extends along a main flow direction. The main flow direction again runs from an outer skin surface, which includes an inlet for the air-workpiece particle mixture, towards an opposite outer skin surface. Due to such an extension, the air-workpiece particle mixture flowing into the collecting container can be reliably, in particular continuously or steadily, decelerated within the collecting container.Turbulence and / or backflow of the air-workpiece particle mixture are avoided or eliminated. The air-workpiece particle mixture is thus distributed with high uniformity within the container body. This allows a comparatively large surface area of ​​the outer skin to contribute to filtering the air-workpiece particle mixture. The previously described filter function can therefore be provided with high reliability.

[0024] Advantageously, the container body extends transversely to the main flow direction in the transport position. It is understood that in the transport position, no air-workpiece particle mixture flows into the container body, and thus, strictly speaking, there is no main flow direction. However, this means that the container body extends transversely to a direction in the transport position, which runs from an outer skin surface containing an inlet for the air-workpiece particle mixture toward an opposite outer skin surface. The collection container is therefore particularly compact in this direction.

[0025] According to one variant, the outer skin has a corrugated or serrated outer skin section, at least in the working position. Such outer skin sections allow an outer skin surface to be locally enlarged without affecting the overall dimensions of the container body. In this way, a relatively large outer skin surface can be provided within a comparatively small volume, which, as already explained, acts as a filter. The filtering properties of the container body are thus improved by means of a corrugated or serrated outer skin section. The corrugated or serrated outer skin section can be formed by at least one corrugated or serrated strut. In this way, a corrugated or serrated outer skin section can be structurally easily formed. In this context, the outer skin can be formed by a covering that is, for example, elastic in sections. However, elasticity is not absolutely necessary.

[0026] In one variant it can be provided that in the working position when viewed along the main flow direction a circumference of the container body remains constant in amount along the main flow direction or changes linearly in amount. Alternatively, in the working position when viewed transversely to the main flow direction a circumference of the container body can remain constant in amount transversely to the main flow direction or change linearly in amount. The change can be an enlargement or a reduction. A linear change is understood to mean that adjacent circumferences, which are plotted for example above the main flow direction or transversely to it, are linearly related, i.e. can be mathematically described by a linear function. If the circumference remains constant in amount, a covering with a constant circumference can be used.This is then pulled over the struts of the container body, with the serrations or waves compensating for each other along the circumference. This allows for the use of a structurally comparatively simple covering. Furthermore, the process of installing the covering is simplified. The same applies whether the circumference increases or decreases linearly. In both cases, the geometry that a corresponding covering must have is developable. This means that a covering mounted on the container body does not need to exhibit elastic stretching or a non-adherent material section. In all variants, the container body has a comparatively large outer skin surface that acts as a filter surface.

[0027] According to one embodiment, at least two corrugated or serrated struts run along the main flow direction, and each circumference extends over a wave crest or a serrated crest of one of the struts and through a wave trough or a serrated valley of the other strut. In this context, a wave crest and a serrated crest are understood to be the portion of the strut that runs above an imaginary zero line. Accordingly, a wave trough or a serrated valley is understood to be the portion of the strut that lies below an imaginary zero line. In this way, corrugated or serrated outer skin sections are generated, which can also be referred to as folded outer skin sections. However, one circumference remains constant along the main flow direction, i.e., wave crests and troughs, as well as serrated crests and troughs, compensate each other around the circumference. Thus, a covering that can be developed circumferentially can be used.Therefore, the covering does not have to be elastically deformable, which of course does not exclude the use of elastically deformable coverings.

[0028] The outer skin preferably has at least one elastically deformable outer skin section. Manipulation of the outer skin by a user can thus be unnecessary when transferring the container body from the transport position to the working position and vice versa. This makes transferring from the transport position to the working position particularly simple. In addition, an elastic outer skin section can be used to specifically apply a force resulting from an elastic deformation to another component of the container body, e.g., to an element of the supporting structure. This allows the container body to be stabilized easily and reliably.

[0029] The collection container can also be transferred from the transport position to the working position and vice versa via an intermediate position. In this case, the elastically deformable outer skin section is maximally stretched in the intermediate position. In other words, the collection container is designed to be bistable and assumes a stable state in both the transport position and the working position. In the intermediate position, the collection container is unstable. This ensures that the collection container always assumes a defined state. The elastically deformable outer skin section acts as a spring or energy storage element. 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 viewing axis.A user of the collection container and a hand tool coupled to it can thus determine the current fill level by looking through the viewing window section into the interior of the collection container. Light can fall into the interior of the collection container through the light incidence section. Consequently, that area of ​​the interior of the collection container is illuminated by light that falls through the light incidence section. The current fill level of the collection container can therefore 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 filter function of 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 comprises 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.

[0030] 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.

[0031] The connecting piece can have a free end that protrudes from the container body. In this case, a connecting piece cover can be provided which is rotatably mounted on the connecting piece and can selectively close and open the connecting piece at the free end. The connecting piece cover therefore closes the connecting piece at the end that protrudes from the container body. Consequently, when the connecting piece cover is closed, at least those sections of the connecting piece through which an air-workpiece particle mixture flows during operation of the collecting container are located on the same side of the connecting piece cover as the container body. In other words, when the connecting piece cover is closed, those sections of the connecting piece through which an air-workpiece particle mixture flows during operation of the collecting container are separated from the surroundings of the collecting container by means of the connecting piece cover.No workpiece particles can escape from this section of the connection piece. Undesired contamination can therefore be ruled out. The rotatable bearing on the connection piece makes it easy to move the nozzle cover from an open state to a closed state and vice versa. It goes without saying that the rotatable bearing of the nozzle cover on the connection piece only allows a rotational movement of the nozzle cover relative to the connection piece. All other degrees of freedom of movement are blocked by the bearing. A further advantage of the nozzle cover of the collecting container according to the invention is that, 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 nozzle cover.

[0032] Furthermore, the object is achieved by an assembly comprising a motor-driven hand tool and a collecting container according to the invention. The collecting container is fluidically coupled to the hand tool such that a mixture of air and workpiece particles can be introduced from the hand tool into the collecting container. The fluid coupling can be achieved, for example, via a connecting piece provided on the collecting container and fluidically connected to the interior of the container body. Due to the fact that the container body has a comparatively large volume in the working position and a comparatively small volume in the operating position, the assembly only needs to be interrupted relatively rarely in order to empty the collecting container. At the same time, the assembly is very compact when it is to be transported, i.e. when the hand tool is not in use and the collecting container is in the transport position.

[0033] In the transport position, a main extension of the container body can be oriented transversely to the main flow direction. In this context, the main extension of the container body refers to its largest dimension in terms of length. This results in a compact assembly consisting of the hand tool and the collection container.

[0034] In one variant, the container body, in the transport position, does not exceed a height of the hand tool defined vertically on a support plate of the hand tool. In this context, a support plate is understood to be a plate-shaped component of the hand tool that is intended to be placed against a workpiece to be machined or to slide along it. Thus, in the transport position, the container body is the same height as or lower than the hand tool. This results in a compact design and easy transportability of the assembly.

[0035] Alternatively or additionally, a length of the container body along a longitudinal direction of the hand tool in the transport position can amount to a maximum of 50% of a length of the support plate. In this context, a longitudinal direction of the tool corresponds to a main working direction of the hand tool. In further preferred variants, a length of the container body along the longitudinal direction of the hand tool in the transport position amounts to a maximum of 20%, a maximum of 30%, or a maximum of 40% of the length of the support plate. In the event that the hand tool is a saw with a circular disk-shaped saw blade, e.g. a circular saw, a length of the container body along a longitudinal direction of the hand tool in the transport position can amount to a maximum of 50% of a saw blade diameter. 50% of the saw blade diameter corresponds to the saw blade radius.

[0036] In one alternative, the width overhang of the container body over the width of the support plate of the hand tool in the transport position is at most 40% of the width of the support plate. More preferably, the width overhang is at most 15%, at most 20%, at most 25%, at most 30%, or at most 35% of the width of the support plate. Such a configuration also ensures that the assembly is compact.

[0037] In the event that the hand tool is a saw with a circular disk-shaped saw blade, e.g. a circular saw, the width overhang may not exceed 50% of the saw blade radius.

[0038] The object is also achieved by a hand tool system comprising an assembly according to the invention and a storage container. The assembly is arranged inside the storage container. In this context, the collecting container is coupled to the hand tool. It therefore does not need to be uncoupled before the hand tool and the collecting container are positioned inside the storage container. This simplifies the handling of the assembly consisting of the hand tool and the collecting container. In a case where the storage container is used for transport, the storage container can also be referred to as a transport container. Such storage containers are sometimes also referred to as "Systainers."

[0039] The container body preferably assumes the transport position. The assembly consisting of the hand tool and the collection container is thus compact. This means that a comparatively small storage container is sufficient to accommodate the assembly consisting of the hand tool and the collection container. The storage container is therefore also compact.

[0040] 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 system and vice versa.

[0065] Figure 27 shows a variant of the collecting container from Figure 26.

[0066] Figure 1 shows a hand tool system 10.

[0067] 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.

[0068] In this example, the motor-driven hand tool 16 is a hand-held circular saw. However, this is purely exemplary.

[0069] 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.

[0070] 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 received.

[0071] 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.

[0072] 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.

[0073] 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.

[0074] The container body 22 assumes a transport position in Figures 1 and 2.

[0075] 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.

[0076] 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.

[0077] 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.

[0078] Furthermore, 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 amounts to approximately 20% of the length 52 of the support plate 44. Furthermore, a width projection 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.

[0079] 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.

[0080] 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.

[0081] The polygon in this case has five polygon corners.

[0082] In the transport position, a polygon corner, ie a joint 30, is accommodated to form a concave outer peripheral section between two polygon edges, ie between two struts 28.

[0083] 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.

[0084] 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.

[0085] 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.

[0086] 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.

[0087] 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.

[0088] The first outer skin length dimension Lmax corresponds to the length of the longest strut 28 of the collecting container 18.

[0089] 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.

[0090] 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.

[0091] In addition, the outer skin 32 comprises at least one elastically deformable outer skin section 58.

[0092] 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.

[0093] 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.

[0094] 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.

[0095] As before, the support structure 26 is polygonal in a lateral view with respect to the main flow direction 34, wherein the joints 30 again form the polygon corners of the polygon shape and the struts 28 again form the polygon edges.

[0096] However, the polygon in this case only has four polygon corners.

[0097] 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.

[0098] 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.

[0099] 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.

[0100] For further details, please refer to the explanations regarding the collecting container 18 according to the first embodiment. Figures 10 and 11 show the assembly 14, with the collecting container 18 being 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.

[0101] 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.

[0102] In the transport position (see Figure 11), the paired struts are essentially placed on top of each other.

[0103] In this context, the first outer skin length dimension Lmax is formed by a region of the outer skin 32 which rests on one of the cross-shaped struts 28.

[0104] In other words, the first outer skin length dimension Lmax again corresponds to the length of the longest strut 28.

[0105] In contrast to the aforementioned embodiments, in the third embodiment the outer skin as a whole is elastically deformable.

[0106] The width overhang in the transport position of the container body now amounts to approximately 15%.

[0107] 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.

[0108] 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. In this embodiment, the struts 28 are each C-shaped.

[0109] 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.

[0110] 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).

[0111] In this context, the first outer skin length dimension Lmax is formed by an arc height of the C-shaped struts 28.

[0112] 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.

[0113] The width overhang in the transport position of the container body now amounts to approximately 15%.

[0114] 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.

[0115] 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.

[0116] 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.

[0117] 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.

[0118] The teeth of the serrated struts 64a, 64b are arranged such that, when viewed along the main flow direction 38, a circumference of the container body 22 along the main flow direction 38 remains constant in amount.

[0119] 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.

[0120] 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.

[0121] In addition, several exemplary circumferences 66a, 66b, 66c are illustrated in Figure 15.

[0122] 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.

[0123] 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.

[0124] 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.

[0125] 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.

[0126] Consequently, the outer skin 32 can be formed without an elastic section. Furthermore, the outer skin 32, especially when unrolled, has a comparatively simple geometry.

[0127] 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.

[0128] 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.

[0129] Again, for a better understanding of the serrated strut 64a, an imaginary zero line NI of the serrations is drawn.

[0130] In addition, several exemplary perimeters 66a, 66b, 66c are again illustrated in Figure 16. In the sixth embodiment, the support structure 26 comprises only a single serrated strut 64a.

[0131] 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.

[0132] 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 delimited by the 64a, wherein the plane in which the prongs extend encloses the same angle with each of these side surfaces.

[0133] The effect of increasing the area while maintaining the same circumference of the outer skin 32 is also achieved in this way.

[0134] 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.

[0135] 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.

[0136] 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.

[0137] 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.

[0138] The connecting piece 20 is also dimensionally stable.

[0139] Furthermore, the dimensionally stable section 68 and the connecting piece 20 are manufactured in one piece.

[0140] 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.

[0141] 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.

[0142] 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.

[0143] Thus, the nozzle cover 74 can selectively close (see Figure 20) and release (see Figures 17 to 19) the connection nozzle 20 at the free end by corresponding rotation about the rotation axis 76.

[0144] The collecting container 18 can only be coupled to the hand tool 16 if the nozzle cover 74 releases the connection nozzle 20.

[0145] The coupled state is characterized by the fact that a connection piece side

[0146] Sealing section 80, which is positioned on an inner circumference 82 of the connecting piece 20 adjacent to the free end 24, is in contact with a hand tool-side sealing section 84 (see Figures 18 and 19).

[0147] 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).

[0148] In this case, a sealing element 88 in the form of a sealing lip is arranged on the connection piece-side sealing section 80.

[0149] A sealing element 90 in the form of a sealing lip is also provided on the hand tool-side sealing section 84.

[0150] The nozzle cover is pre-tensioned into the closed position by means of a spring device 92.

[0151] The nozzle cover 74 is shown in isolation in Figures 22 and 23.

[0152] The nozzle cover 74 has a closure portion 94 which is designed to selectively close the free end 24 of the connection nozzle 20.

[0153] 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.

[0154] The nozzle cover 74 is designed as a single, continuous component. Accordingly, the closure portion 94 and the actuating portion 96 are also designed as a single piece but separately from one another. The closure portion 94 and the actuating portion 96 form an obtuse angle 100° in a plane of rotation, i.e., viewed along the axis of rotation 76.

[0155] In addition, the locking portion 94 and the actuating portion 96 are positioned on opposite sides of the rotation axis 76.

[0156] In other words, the closure portion 94 and the actuating portion 96 are spaced apart from each other.

[0157] Furthermore, a retaining rib 102 with a mounting bevel 104 is formed on the closure section 94.

[0158] 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).

[0159] The retaining rib 102 is positioned on a side of the closure portion 94 facing the connecting piece 20. Accordingly, in the closed position, the retaining rib 102 projects into the interior of the connecting piece 20.

[0160] A recess 106 is also provided on the closure section 94.

[0161] 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).

[0162] The recess 106 is also positioned on a side of the closure section 84 facing the connecting piece 20.

[0163] The retaining rib 102 is closer to the rotation axis 76 than the recess 106.

[0164] 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. 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.

[0165] The retaining bead 112 is also provided with a mounting bevel 114.

[0166] 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.

[0167] 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).

[0168] 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.

[0169] This can be done by applying an actuating pressure force to the actuating section 96.

[0170] 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 the hand tool 16.

[0171] 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). In such a position of the nozzle cover 74, the connecting nozzle 20 can be pulled off the outlet 108 with little resistance or pushed onto the outlet 108. 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.

[0172] 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.

[0173] In order 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).

[0174] Above, the nozzle cover 74 and the associated features of the collecting container 18 and the motor-driven hand tool 16 were explained using the collecting container 18 according to the first embodiment (see Figures 1 to 6). However, it should be understood that the explanations regarding the nozzle cover 74 and the associated features of the collecting container 18 and the motor-driven hand tool 16 apply equally to the other embodiments of the collecting container 18.

[0175] As can be seen from Figure 24, the dimensionally stable portion 68 of the outer skin 32 further comprises an emptying opening 120.

[0176] 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 fill level of the container body 22 with workpiece particles is reached during machining of the workpiece. 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.

[0177] In the illustrated embodiment, the closure means 122 is designed as a dimensionally stable lid 124.

[0178] 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.

[0179] 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.

[0180] 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.

[0181] Thus, the inlet opening 21 and the discharge opening 120 are positioned on the same outer skin surface of the outer skin 32.

[0182] 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.

[0183] 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.

[0184] 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 grasped simultaneously with different fingers of a single human hand. In other words, the locking unit 130 can be actuated with a single human hand. Figure 24 shows the hand tool 16 in a processing position. In Figure 24, a processing zone 132 is located below the hand tool 16.

[0185] 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.

[0186] 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 24, the force of gravity acts in the closing direction on the closure means 122 and the container body 22.

[0187] Furthermore, in a use position of the collecting container 18, ie in the position shown in Figure 24, 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.

[0188] 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.

[0189] 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.

[0190] Figure 25 shows a variant of the embodiment of Figure 24. 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.

[0191] Figure 25 also shows the hand tool 16 in a processing position. Here, the processing zone 132 is again located below the hand tool 16. 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 from Figure 25, the emptying direction 134 is oriented vertically. It therefore only has component 136, which points vertically downward toward the processing zone 132.

[0192] Both with the collecting container 18 according to the variant from Figure 24 and with the collecting container according to the variant from Figure 25, 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.

[0193] 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.

[0194] In a first step, the closure means 122 is unlocked by actuating the locking unit 130.

[0195] Subsequently, in the variant according to Figure 24, 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.

[0196] 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.

[0197] 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.

[0198] 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.

[0199] In the variant according to Figure 25, the closure means 126 is folded downwards supported by gravity.

[0200] 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.

[0201] When a sufficient amount 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 the force of gravity and locked there to the frame 126 by means of the locking unit 130.

[0202] It is again understood that the explanations of Figures 24 and 25 apply not only in connection with the first embodiment of the collecting container 18, but can be combined with all embodiments explained above.

[0203] Figure 26 shows the collecting container 18 according to the first embodiment from Figures 3 and 4 in another perspective view.

[0204] Figure 26 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.

[0205] It is made of a textile material with a white or light grey colour that is dimensionally unstable.

[0206] The light incidence section 138 thus contributes to a filtering effect of the outer skin 32. Furthermore, light can enter the interior of the container body via the light incidence section 138.

[0207] In addition, the outer skin 32 has a viewing window section 140.

[0208] This is made of an optically transparent, shape-stable plastic material. This material can also be referred to as plastic film.

[0209] 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.

[0210] 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.

[0211] 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.

[0212] The antistatic portion 142 is further electrically connected to an electrical connection contact 144 arranged on the connection piece 20.

[0213] Alternatively, the antistatic section 142 can comprise a material with hydrophilic properties, so that an electrostatic charge can be released into 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. The electrical connection contact 144 is designed to enable electrical potential equalization between the antistatic section 142 and the hand tool 16.

[0214] 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.

[0215] 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.

[0216] 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.

[0217] The first outer skin surface 146 and the second outer skin surface 148 adjoin one another at an outer skin edge 150.

[0218] The light incidence section 148 and the viewing window section 140 thus delimit a transmitted light zone 152 which extends inside the container body 22.

[0219] 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.

[0220] 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.

[0221] Optionally, the viewing window section 140 is provided with a fill level scale 156 for this purpose. 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.

[0222] Figure 27 shows a further variant of the collecting container 18 according to the first embodiment from Figures 3 and 4.

[0223] 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.

[0224] Thus, the light incidence section 138 and the connecting piece 20 are arranged on the same outer skin surface.

[0225] The viewing window section 140 is realized in the same way as in the embodiment according to Figure 26.

[0226] Since in the variant shown in Figure 27 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.

[0227] It is again understood that the explanations of Figures 26 and 27 apply not only in connection with the first embodiment of the collecting container 18, but can be combined with all embodiments explained above.
