Abstract

The present invention relates to a tool (10) for reworking and smoothing joints filled with a jointing compound, wherein the tool (10) comprises a substantially plate-shaped body which has an edge extending, in particular perpendicular to the plane of the plate, with differently curved sections. It is provided that the body is constructed in multiple parts and comprises a first part (1) with a first curved edge section (31) and a second part (2) with a second curved edge section (32), wherein the parts (1, 2) have connecting means (41, 42) for creating a detachable connection with one another.

Description

[0001] The present invention relates to a tool for reworking and smoothing joints filled with a joint compound, according to the preamble of claim 1.

[0002] Such joints come in a variety of shapes and sizes, for example, between tiles or between a pane of glass and a frame, and are usually filled with elastic joint sealants such as mortar or silicone for sealing purposes. The joint sealant is typically applied to the joint in a malleable state and hardens after some time. Various tools are known in the art to smooth the joint sealant and give the final joint a pleasing visual appearance.

[0003] EP 0 711 887 A1 discloses a tool for refinishing joints, which consists of a plate with a circumferential edge projecting perpendicularly to the plate plane on both sides. The plate has a substantially triangular shape, with one of the ends curved and two straight. The longer of the two straight ends and the curved end form an acute angle and merge into one another in an arc, so that this rounded corner can be used to remove excess joint compound and create concave joint surfaces.

[0004] To expand the range of possible joint shapes and curvatures, EP 0 810 337 A1 proposes a tool with an essentially boomerang-shaped plate featuring two rounded corners with different radii of curvature. However, due to the extended shape of this tool, the joint material to be processed can sometimes be difficult or even impossible to access in confined joint spaces. Furthermore, despite the second rounded corner, the number of possible joint shapes remains limited even with this tool.

[0005] From DE 20 2019 100 122 U1 a tool with several scraper blades is known, which are rotatably mounted on a common joint and have differently shaped working heads.

[0006] The present invention is therefore based on the object of providing a tool for reworking and smoothing joints filled with joint compound, which allows a larger number of joint shapes to be produced and at the same time allows the processing of joints in confined spaces.

[0007] This object is achieved according to the invention by a tool having the features of claim 1. Advantageous embodiments of the invention emerge from the subclaims and the following description.

[0008] Starting from a generic tool with a substantially plate-shaped body and an edge with differently curved sections, it is proposed to construct the body in several parts and to provide a first part and a second part with connecting means by means of which the parts can be detachably connected to one another. The connecting means are in particular an integral part of the first and second parts, i.e. no external or separate connecting means are provided for connecting the tool parts. According to the invention, the first part has a first curved edge section and the second part a second curved edge section, i.e. each of the detachable parts comprises at least one curved edge section for producing concavely shaped joints.

[0009] This means that each of the parts can be used as a separate tool for refinishing and smoothing joints filled with joint compound. Compared to a single body, a longer edge area and more corners are available, and therefore a potentially larger number of possible edge shapes and curves for creating and processing a wide variety of joint shapes. The advantage over separate, permanently separated tools is that the individual tool parts can be assembled into a single body, which simplifies storage and transport. The individual parts cannot easily be lost and there is no need to carry several separate parts. If necessary, the individual parts can be taken apart and used as standalone tools, for example in a cramped joint environment where the large, assembled tool would be too bulky.

[0010] The assembled body can essentially have a boomerang shape, as is known in principle from EP 0 810 337 A1. This provides the additional advantage of ergonomic handling. The pistol-grip shape when assembled allows the tool to be held securely and comfortably in the hand and guided along the joint to be worked on.

[0011] In one possible embodiment, the edge of the plate-shaped body extends at least partially perpendicular to the plate plane, i.e., it is formed at least partially by end faces extending perpendicular to the plate plane. In particular, the edge can extend perpendicular to the plate plane in the region of the first and second curved edge sections.

[0012] In one possible embodiment, the first and second curved edge sections are curved to different degrees. This allows these edge sections to be used to create joints with differently curved surfaces. The first and / or second edge section can have a constant curvature with a defined radius of curvature. In this case, the first and second curved edge sections preferably have different radii of curvature.

[0013] In a further possible embodiment, the edge of the first part comprises a first end face and a second end face, which merge into one another via the first curved edge section. The transition between the first curved edge section and the adjacent end faces is in particular continuous, i.e., formed without abrupt edges. The first and second end faces and the first curved edge section form sections of the edge surrounding the first part, preferably extend perpendicular to the plate plane of the first part, and preferably have a constant width perpendicular to the plate plane.

[0014] The first end face preferably has a straight or flat profile in the peripheral direction of the edge. Alternatively or additionally, the second end face preferably has a convexly curved profile in the peripheral direction of the edge, with the first curved edge section being more strongly curved than the second end face. By continuously transitioning the more pronounced curvature of the first curved edge section into the less pronounced or "gentler" curvature of the second end face, a depth of the smoothed joint can be varied as desired. For example, the second end face of the first part can be used to create floor joints due to its smaller curvature, while the more strongly curved first edge section and the rounded corner formed thereby between the first and second end faces allow for the creation of smaller, rounded joints, such as bathroom or balcony joints.

[0015] In a further possible embodiment, it is provided that the first part has a substantially triangular shape, wherein the first and second end faces preferably form an acute angle (0° < α ≤ 90°) with each other. In the case of a convexly curved second end face, this may mean that the first end face forms an acute angle with a tangent at the transition between the second end face and the first curved edge portion, in particular with any tangent to the second end face outside the first curved edge portion. The transition between the first curved edge portion and the second end face may be characterized by a (preferably continuous or steady) change in the radius of curvature of the edge.

[0016] The first and second end faces, which converge and end in the first curved edge section, or the shape of the first part, which tapers towards the first curved edge section, enable joints to be processed even in areas with poor spatial accessibility.

[0017] In a further possible embodiment, the first part has a third end face on which at least one first connecting means is arranged for establishing the detachable connection to the second part. The at least one first connecting means is preferably formed integrally with the first part or the corresponding partial body. The first curved edge section preferably forms a corner of the first part opposite the third end face, so that the first curved edge section forms an outer and easily accessible end of the tool, with which joints to be machined can be easily reached, even when connected to the second part.

[0018] In a further possible embodiment, the edge of the first part has a third curved edge portion, which is preferably formed on a first projection that borders the third end face. Because the third curved edge portion is formed on a protruding projection, joints to be machined between components inclined relative to one another can be better reached. The first projection can preferably taper toward the third curved edge portion and, in particular, transitions continuously into the second and / or third end face.

[0019] The additional "nose" thus formed represents, in addition to the first curved edge section, another working edge of the first part, with which joints can be smoothed. Preferably, the third curved edge section is more curved than the first and / or second curved edge section, thus expanding the range of joint surfaces that can be produced with the tool according to the invention. This additional nose in the area of the third end face enables, for example, the production of smaller joints.

[0020] In a further possible embodiment, the edge of the first part has a stripping edge running perpendicular to the plane of the panel, which is preferably formed on a second projection that borders the third end face. Because the stripping edge is formed on a protruding projection, points to be worked on between components that are inclined towards one another can be reached more easily. The second projection can preferably taper towards the stripping edge and in particular merges continuously into the first and / or third end face. The additional stripping edge can be used to clean the area around the joint of joint compound or to smooth the joint edges, for example if smeared joint material is still left on a glass pane or tile after the joint has been worked on.Due to the comparatively sharp contour of this scraper edge (which can also be seen as a rounded corner with a very small radius of curvature), even special joints of small width can be created, e.g. between the glass pane and the frame.

[0021] In a further possible embodiment, both the described peel-off edge and the third curved edge section are formed on the first part, and, viewed along the circumferential direction of the edge, the third curved edge section is formed between the third and second end faces, and the peel-off edge is formed between the third and first end faces. Alternatively, conversely, the third curved edge section can be formed between the third and first end faces, and the peel-off edge can be formed between the third and second end faces. The peel-off edge and the third curved edge section are thus located, so to speak, at the corners between the third end face and the first and second end faces of the first part, or form these corners.

[0022] The peeling edge or the third curved edge section, as well as the third end face, form, in particular, sections of the edge surrounding the first part and run perpendicular to the plate plane of the first part. The third end face can have a varying width perpendicular to the plate plane or a width that differs from the first and second end faces.

[0023] The additional stripping edge or the third curved edge section in the area of the third end face is available in particular because the tool is designed in several parts and therefore the first part, when released, has additional corners that can be used for joint processing.

[0024] In a further possible embodiment, the edge of the second part has a fourth end face and a fifth end face, which merge into one another via the second curved edge section. The transition between the second curved edge section and the adjacent end faces is, in particular, continuous, i.e., formed without abrupt edges. The fourth and fifth end faces and the second curved edge section form sections of the edge surrounding the second part, extend perpendicular to the plate plane of the second part, and preferably have a constant width perpendicular to the plate plane.

[0025] The fourth end face and / or the fifth end face preferably have a straight or flat profile in the peripheral direction of the edge. Alternatively, the fourth or fifth end face can have a convexly curved profile, in which case the curvature can differ from that of the second end face of the first part to enable different joint surfaces.

[0026] In a further possible embodiment, it is provided that the fourth and fifth end faces form an acute angle (0° < α ≤ 90°) with each other. Due to the fourth and fifth end faces converging and ending in the second curved edge section, i.e. due to the shape of the second part tapering towards the second curved edge section, it is possible to process joints even in areas with poor spatial accessibility.

[0027] In a further possible embodiment, the second part has a sixth end face on which at least one second connecting means is arranged for establishing the detachable connection to the first part. The at least one second connecting means can in particular be connected or engaged with the at least one first connecting means of the first part and is preferably formed integrally with the second part. The sixth end face preferably forms a side of the second part opposite the fourth end face.

[0028] The second part can essentially have the shape of a shoe, with the second curved edge portion forming the "toe" and preferably the fourth end face forming the "sole." The sixth end face can, to continue with this analogy, form the upper side in the area of the "entry opening" of the shoe, which preferably merges into the second curved edge portion via the fifth end face.

[0029] In a further possible embodiment, it is provided that the first part and / or the second part has a seventh end face in the form of a surface of an edge region that is bevelled on one side and tapers at an acute angle to a cutting edge running parallel to the plane of the panel. In other words, the seventh end face preferably forms a cutting edge in that it runs from an upper side of the second part to its underside, bevelled on one side, wherein, starting from the upper side, the width decreases perpendicular to the plane of the panel to the underside at an acute angle. The scraper blade or edge shaped in this way can be used to clean the area around joints of joint material over larger areas or to smooth the joint edges, for example if smeared joint material is still present on a glass pane or tile after joint processing. The cutting edge can have a linear or a convex or concave curved profile.

[0030] Preferably, the seventh end face is arranged on the second part, with the second curved edge section in particular forming a rounded corner of the second part opposite the seventh end face. Referring to the previously used shoe analogy, the seventh end face preferably forms the "shoe rear part," which extends between the "entry opening" (sixth end face) and the "shoe sole" (fourth end face).

[0031] It is advantageous if the seventh end face or the cutting edge forms a right angle with the fourth end face and merges into it via a sharp edge or corner. This allows the cutting edge to be inserted or the second part to be placed on surfaces and corner areas arranged at right angles to each other.

[0032] The edge of the plate-shaped body preferably runs perpendicular to the plate plane everywhere except for the seventh end face or the cutting edge.

[0033] Preferably, the first and second parts are configured such that the cutting edge, and in particular the corner between the cutting edge and the fourth end face, can be used and is accessible even when the tool is assembled. This allows the cutting edge to be used with the large, assembled tool or with the individual second part, as needed.

[0034] In a further possible embodiment, the connecting means are designed such that they can be pushed into one another perpendicular to the plane of the panel to establish the connection between the first and second parts. Preferably, the first connecting means form projections projecting from the third end face, and the second connecting means form recesses complementary thereto, or vice versa. To ensure a stable connection, preferably at least two projections and correspondingly at least two recesses are provided.

[0035] Ideally, the connecting means secure the parts in a form-fitting manner in every direction parallel to the plane of the plate when connected. In other words, the connecting means are preferably designed such that the parts cannot be moved relative to one another along the plane of the plate when connected, and the parts cannot be separated from one another in this direction. In contrast, the connecting means preferably allow relative movement of the parts perpendicular to the plane of the plate, preferably only from one side.

[0036] In a further possible embodiment, the connecting means are at least partially conical in shape, which is designed such that sliding the connecting means into one another is only possible until a connecting position is reached in which the plate planes of the first and second parts lie in a common plane. The connecting position here refers to a relative position of the parts to one another in which they are connected to one another and can be used as a common tool. A conical shape of the connecting means is understood here to mean that at least part of the connecting means tapers perpendicular to the plate plane.

[0037] The conical shape of the connecting elements means that the tool parts can only be connected from one side. Once the connecting elements are fully pushed together and the parts have thus reached their connecting position, any further movement of the parts relative to one another is blocked. This prevents the connecting elements from slipping. Since the body of the tool is preferably made of an elastic plastic such as a thermoplastic or an elastomer, the conical shape of the connecting elements also clamps the parts when they are pressed against each other into the connecting position, creating a stable connection and preventing the parts from accidentally falling apart.

[0038] In a further possible embodiment, the first and second parts each have two opposing, concavely shaped side surfaces, each of which is at least partially surrounded by a circumferential seam. The seam is delimited outwardly by the edge of the respective part. Towards the inside (i.e., toward the center of the respective side surface), the seam preferably transitions continuously into the concave region, i.e., in particular, without an abrupt step or 90° edge.

[0039] The concave areas can serve as handles or gripping surfaces, thus improving ergonomics when holding and guiding the tool or individual parts. Furthermore, the concave areas collect removed joint material, preventing it from falling off the tool during joint processing and contaminating the joint area.

[0040] The circumferential seam preferably has a flat profile and, if appropriate, a constant width at least in sections, and at least partially surrounds the respective concave region. In the region of the optionally provided additional projections of the first part, i.e., the third curved edge section and / or the peel-off edge, the seam can be wider.

[0041] The surrounding seam serves, on the one hand, to stiffen the body and its respective components at their edges, creating stable edges that won't crack or break apart after even minimal use. Furthermore, the surrounding seam encloses any grout that has accumulated or accumulated in the concave area, allowing it to be removed from the body after use or at regular intervals. Because the seam seamlessly transitions into the concave area and there is no sharp edge or step, grout cannot settle and dry there, which would be difficult to remove.

[0042] The concave regions of the first and second parts are preferably configured such that, when joined, they merge continuously, i.e., without abrupt edges. Thus, the third and sixth end faces of the first and second parts can have a smaller width perpendicular to the plane of the plate than the other end faces, since they extend within the concave regions of the respective side surfaces and ensure that, when the parts are joined together, a single, continuous concave region is formed on each side surface.

[0043] Optionally, it can be provided that the first part and / or the second part has an inner cavity which can be filled with air, for example. This makes it possible to design the tool according to the invention such that it floats in water and does not sink. As an alternative to or in addition to a cavity filled with a gas or a liquid, this effect can also be achieved in that the first part and / or the second part, which is made of a first material (e.g. a first thermoplastic or a first elastomer), has an inner region made of at least one second material (e.g. a second thermoplastic or a second elastomer) and at least partially encloses this. The use of a two-component injection molding is conceivable, for example.The different materials can be selected in such a way that the first and / or second part has a stable, elastic structure that enables good joint processing, while at the same time the second material ensures the buoyancy of the tool.

[0044] Preferably, the lateral edges of the first and second end faces and the first curved edge region of the first part and / or the lateral edges of the fourth and fifth end faces and the second curved edge region of the second part run parallel to one another (in the case of the fourth end face, apart from the optionally provided region in which it tapers to the cutting edge described above).

[0045] Further features, details, and advantages of the invention will become apparent from the following exemplary embodiment explained with reference to the figures. They show: Figure 1: the tool according to the invention according to a preferred embodiment in the assembled state in a plan view of one of the side surfaces; Figure 2: a cross section through the tool according to Figure 1 ; Figure 3: the first part of the tool according to Figure 1 in a single view; and Figure 4: the second part of the tool according to Figure 1 in a single view.

[0046] In the Figure 1A first exemplary embodiment of the tool 10 according to the invention is shown in the connected state in a plan view of one of the side surfaces. The tool 10 comprises a substantially plate-shaped body, which can be made of an elastic plastic such as a thermoplastic or an elastomer. The edge of the body comprises various curved regions 31, 32 and end faces 11, 12, 24, 25, which are described in detail below. The body is essentially in the shape of a boomerang and comprises two legs with rounded ends 31, 32, which serve to remove joint compound or to create joints with a curved surface. In addition, the body has a cutting edge 28 for cleaning the area around the joint of joint material or for smoothing the joint edges.

[0047] The body comprises a first end face 11 with a flat or straight profile and a second end face 12 with an arcuate, or more precisely, convexly curved profile. The second end face 12 can have a constant curvature over its entire length, although a varying curvature is also conceivable. The second end face 12 merges continuously into the first end face 11 via a first curved edge section 31, the first curved edge section 31 being more curved than the second end face 12 and forming a rounded corner of the tool 10. The first and second end faces 11, 12 converge parallel to the plate plane, so that the leg formed by the first and second end faces 11, 12 tapers towards the first curved edge section 31.It can be provided that the first end face 11 forms an acute angle with each tangent adjacent to the second end face 2 (outside the first curved edge section 31).

[0048] At its end opposite the first curved edge section 31, the second end face 12 terminates in a projection with a third curved edge section 33, which, however, is not visible when the tool is assembled and is described further below. At its end opposite the first curved edge section 31, the first end face 11 transitions via a short, convexly curved section into a fifth end face 25 with a flat profile. A fourth end face 24 of the body also has a flat profile and transitions continuously via a second curved edge section 32 into the fifth end face 25. The fourth end face 24 preferably forms an acute angle with the fifth end face 25.

[0049] The second curved edge portion 32 is preferably more curved than the first curved edge portion 31 (and thus, in particular, also than the second end face 12). In particular, the first and second curved edge portions 31, 32 each have a constant curvature, with the second curved edge portion 32 having a smaller radius of curvature than the first curved edge portion 31. These rounded corners of the tool 10 allow different joint shapes or curvatures to be achieved, which expands the range of applications of the tool 10.

[0050] The first, second, fourth, and fifth end faces 11, 12, 24, 25, as well as the first and second curved edge sections 31, 32, extend perpendicular to the plate plane along which the body extends, and preferably have a constant width perpendicular to the plate plane (except for the end section of the fourth end face 24 bordering the cutting edge 28), which width particularly defines the maximum width of the tool 10. The aforementioned end faces 11, 12, 24, 25 and curved edge sections 31, 32 are each delimited perpendicular to the plate plane by two parallel lateral edges 6 (cf. Figure 2 ), the distance between which defines the width of the respective edge section.

[0051] In addition, the body comprises a seventh end face 27, which, however, is not perpendicular to the plane of the plate, but rather diagonally to it. Starting from an upper side of the body (which in the Figure 1can be seen), the seventh side surface 27 runs obliquely downwards and ends in the cutting edge 28. The latter is formed by the body tapering towards the cutting edge 28, i.e. the thickness of the body decreases towards the cutting edge 28, preferably at an acute angle.

[0052] As in the Figure 1As can be seen, the cutting edge 28 in the exemplary embodiment discussed here does not have a linear, but rather a slightly convex curved profile. The cutting edge 28 is separated from the second end face 12 by the aforementioned projection with the third curved edge section 33. The second end face 12 and the cutting edge 28 are preferably shaped such that overall an outer contour is produced with a uniform, continuous curvature that extends over both regions 12, 28. The aforementioned outer contour can have a constant curvature overall, but this is not mandatory. An embodiment is also conceivable in which the cutting edge projects beyond the second end face 12 or is set back.

[0053] The cutting edge 28 preferably forms a right angle with the adjacent fourth side surface 24 at the transition point, ie the body preferably has a right-angled corner at this point.

[0054] The body has two sides, one of which is in the Figure 1 shown in plan view. The side surfaces each have a concavely shaped region 50, which is surrounded by a flat seam 52 towards the outside, towards the lateral edges 6 of the end faces 11, 12, 24, 25 and curved edge sections 31, 32. The seam 52 surrounds the respective concave region 50 in the assembled state of the tool (cf. Figure 1 ) complete.

[0055] According to the invention, the body is not formed in one piece, but in several parts. The exemplary embodiment shown in the figures shows a tool 10 with a two-part body, which comprises a first part 1 and a second part 2. The two parts 1, 2 each comprise connecting means 41, 42, by means of which they can be detachably connected to one another. Figure 1 shows the tool 10 in the assembled state, ie the first and second parts 1, 2 are connected to each other via their connecting means 41, 42.

[0056] In principle, more than two parts 1, 2 could be provided, each of which can be connected to each other via appropriate connecting means.

[0057] In the Figure 2 is a cross section through the assembled tool 10 along the Figure 1shown by the dashed line A, which runs through two interconnected connecting means 41, 42. The outer lines, forming a rectangle, represent the lateral edges 6 of the end faces 11, 12, 24, 25 with a constant width, while the two inner, concavely curved lines indicate the thickness of the body along the cutting line A. This shows the shape of the concave regions 50 of the side surfaces, which merge into the circumferential seam 52 without sharp steps or edges.

[0058] The two parts 1, 2 of the tool 10 are individually in the Figures 3 and 4each shown in a plan view of their side surfaces. The first part 1 has a substantially triangular shape (and, like the entire body, is substantially plate-shaped) and comprises the previously described first and second end faces 11, 12 as well as the first curved edge portion 31. The second part 2, which is also substantially plate-shaped, in contrast, has substantially the shape of a shoe and comprises the aforementioned fourth, fifth, and seventh end faces 24, 25, 27 (i.e., also the cutting edge 28) as well as the second curved edge portion 32.

[0059] The first part 1 has a third end face 13, on which, in the exemplary embodiment shown here, two first connecting means 41 are formed in the form of T-shaped recesses that extend into the partial body of the first part 1. The second part 2 also has a further, sixth end face 26, on which second connecting means 42 are formed, complementary to the recesses 41, in the form of T-shaped projections that protrude from the partial body of the second part 2 in the plate plane. The first and second connecting means 41, 42 are therefore preferably formed integrally with the first and second parts 1, 2 and, in particular, also consist of an elastic plastic.

[0060] The projections 42 are conical in shape and taper perpendicular to the plate plane in the direction of Figure 4 . The recesses 41 are also conical in shape (in the Figure 3not indicated). As a result, the projections 42 can be pushed perpendicular to the plate plane into the recesses 41 from one side only, until a connecting position is reached in which the projections 42 lie completely within the complementarily shaped recesses 42. In the connecting position (cf. Figure 1) the plate planes (these are defined in particular by the planes running centrally, i.e. at half the thickness through the respective partial bodies) lie in a common plane. In addition, the side surfaces of the first and second parts 1, 2 adjoin one another continuously in the connecting position, i.e. without a jump. The concave regions 50 of the side surfaces are shaped in particular such that the concave edges of the concave regions 50, which form the lateral edges of the third and sixth end faces 13, 26, abut one another in the connecting position, so that a continuous concave region 50 is formed on each side surface of the assembled tool (cf. Figure 1 ).

[0061] This design of the connecting means 41, 42 allows the two parts 1, 2 to be pushed together only from one side and only in a defined relative orientation. This not only ensures a connection that can be made easily and correctly, but also prevents the two parts 1, 2 from slipping through each other or being pushed too far together during connection. Once the connection position is reached, the parts 1, 2 can no longer be pushed together any further. Furthermore, the preferably elastic design of the connecting means 41, 42 ensures that after the parts 1, 2 are pressed together, they remain firmly connected to one another and do not accidentally separate from one another.

[0062] The connecting means 41, 42 secure the parts 1, 2 in a form-fitting manner relative to one another in every direction parallel to the plane of the panel when connected. Due to their conical shape, the parts 1, 2 are also positively secured perpendicular to the plane of the panel in the insertion direction when connected, while movement in the opposite direction (to release the connection) is possible, and in this direction, in particular, only a force-fitting connection exists.

[0063] Instead of the wing-shaped or T-shaped connecting means 41, 42 shown here, any other shapes are conceivable that allow the connecting means to be pushed into one another and thus to create a detachable connection between the first and second parts 1, 2. Furthermore, only one connecting means or more than two connecting means can be provided per part 1, 2.

[0064] The division of the tool 10 creates additional working edges and end faces, which significantly expand the range of applications of the tool 10 according to the invention. Thus, in the exemplary embodiment shown here, the first part 1 has, in the transition area between the second end face 12 and the third end face 13 caused by the division, an additional first projection or nose with a third curved edge section 33. This is preferably more curved than the first and second curved edge sections 31, 32 and therefore enables the production or machining of even smaller joints. The third curved edge section 33 lies between the second and third end faces 12, 13 and, in particular, merges continuously into them.

[0065] At the other end of the third end face 13, an additional second projection in the form of a fin is also provided, which tapers parallel to the panel plane to a preferably linear stripping edge 34 running perpendicular to the panel plane, in particular at an acute angle. The second additional projection is formed by the division of the body into the first and second parts 1, 2 slanting into the first end face 11 or into the concavely curved edge section between the first and fifth end faces 11, 25. This additional stripping edge 34 enables pinpoint cleaning of smeared joint material from the area surrounding the joint, as well as precise production of the finest joints between components angled to one another.

[0066] In principle, it would be conceivable to provide the first and / or second additional projection not on the first part 1, but on the second part 2. Furthermore, both parts 1, 2 could optionally have additional projections or working edges at the corners of the respective third and sixth end faces 13, 26. List of reference symbols:
