Description

The present invention relates to a profile leg, an edge plaster profile with a first such profile leg and a second profile leg and the use of such an edge plaster profile.

A profile leg with the features of the preamble of claim 1 is from US 2007/0022688 A1 known.

Edge plaster profiles are used in corner areas of walls, on the one hand to provide a pull-off edge necessary for plastering and, on the other hand, to provide stabilization in the edge area so that the edge does not break even when it is lightly used. By using different edge plaster profiles, which differ in terms of the angle formed by the profile legs, different plaster thicknesses can be implemented or edges can be plastered with different angles.

Common edge plaster profiles are often made of metal. With such edge plaster profiles made of metal, well-stabilized corner areas can be realized, but their production is relatively complex and expensive. The production effort increases further if these edge plaster profiles made of metal have to be additionally galvanized in order to achieve a corresponding corrosion resistance. In addition, with such edge plaster profiles, the angle formed by the profile legs cannot be changed. As a consequence, a different edge plaster profile must be kept for different plaster thicknesses be used. It would be conceivable to change the angle formed by the profile legs by bending the edge plaster profile, for example on the construction site, but in practice it is not possible to set a uniform angle over the entire length of the edge plaster profile, so that such a bent edge plaster profile for the creation of a clean plaster edge would be unsuitable.

In the case of edge plaster profiles made of plastic, on the other hand, it is not possible to adjust the angle by bending, since they are usually made of rigid PVC. Therefore, such edge plaster profiles must be produced and stored separately for each desired plaster thickness.

It is an object of the present invention to provide a profile leg for forming an edge plaster profile or an edge plaster profile, which can be produced inexpensively and can be used for different plaster thicknesses and edge angles. Furthermore, the profile leg or the edge plaster profile should be easy to use.

The object is achieved by a profile leg with the features of claim 1.

The profile leg has a leg surface, the leg surface being delimited at opposite ends by a corner longitudinal edge and a distal longitudinal edge, and the profile leg having a connecting section along its corner longitudinal edge. The profile leg according to the invention has a hinge axis on the connecting section and has a hinge bush on the distal longitudinal edge. Preferably, the hinge axis and the hinge bush are dimensioned so that the hinge axis in the hinge bush, for example another identical profile leg or the same profile leg, after this, preferably in the longitudinal direction, divided, can be clamped in such a way that a non-positive connection is created between the hinge axis and the hinge bushing.

In order to facilitate dividing the profile leg, preferably in the longitudinal direction, the profile leg preferably comprises a dividing aid between the corner longitudinal edge and the distal longitudinal edge, along which the profile leg can be divided. The dividing aid can be designed, for example, as a perforation that extends, preferably in the longitudinal direction, over the leg surface. Alternatively, the dividing aid can also be designed as a web which extends over the leg surface of the profile leg, preferably in the longitudinal direction. The web can be used to guide a cutting tool, such as a knife or saw, in order to divide the profile leg along the dividing aid. Instead of or in addition to a web and / or a perforation, a groove can also be provided in which a cutting tool can also be guided.

The invention also relates to an edge trim profile with a first profile leg, which is formed in one of the ways described above, and a second profile leg, which has a leg surface that is delimited at opposite ends by a corner longitudinal edge and a distal longitudinal edge, and the has a connecting section along its corner longitudinal edge, the connecting sections of the two profile legs being connected to one another by a hinge which is designed for setting and fixing an angle between the profile legs.

According to the invention, the edge trim profile has a first profile leg and a second profile leg. The two profile legs each have a leg surface, the two leg surfaces being delimited at opposite ends by a corner longitudinal edge and a distal longitudinal edge. The two profile legs each have a connecting section along their corner longitudinal edges. The connecting sections of the two profile legs are connected to one another by a hinge which is designed for setting and fixing an angle between the profile legs.

By attaching a hinge between the two profile legs, the edge trim profile according to the invention has the advantage that the angle formed by the profile legs can be set variably. The fact that the hinge is designed not only for setting, but also for setting the angle, ensures that the angle is not readjusted after setting, for example solely due to the elasticity of the material from which it was made. Thus, the desired angle of the edge plaster profile can be set precisely and permanently so that it can then be placed on a wall to be plastered. In addition, when the edge plaster profile is pressed against the wall edge to be plastered, a clamping effect is created due to the specified angle, by which the two profile legs are pressed against the respective wall section of the edge. When the edge plaster profile is pre-fastened in the desired position, which is usually done by so-called plaster lumps, this pre-fastening is thus reinforced, since a tendency for the profile legs to lift off the wall and thus detachment of the plaster lumps is counteracted. The possibility of adjusting the angle formed by the profile legs also makes it possible to plaster edges with different angles with a single type of edge plaster profile. Thanks to the adjustability of the angle, the same edge plaster profiles can also be used for different plaster thicknesses. This reduces production costs and storage costs, since only one type of edge plaster profile has to be produced for different edge angles and plaster thicknesses. There is also no need to keep several different edge plaster profiles. The connection with a hinge can be done in different ways and be permanent or detachable.

The edge trim profile is advantageously made of plastic. In comparison to known edge plaster profiles made of metal, the edge plaster profile according to the invention can be manufactured much more economically. In particular, methods known from plastics processing, such as injection molding, extrusion or coextrusion, can be used. A complex production with several steps, as is necessary for edge plaster profiles made of metal, such as cutting and shaping the metal, can be dispensed with. Furthermore, the production of the edge trim profile from plastic enables the edge trim profile according to the invention to be much lighter than an edge trim profile made from metal. In principle, the edge trim profile can also consist of metal, for example of galvanized steel, in particular strip steel. Production from a combination of materials, in particular a combination of plastic and metal, is also conceivable. Here, for example, the hinge could be made of plastic and the profile legs could be made at least essentially of metal.

The edge trim profile is advantageously designed to be foldable by the hinge. In particular, the hinge can allow complete or almost complete folding together, so that the two profile legs come to rest completely or almost completely on one another. Both the storage and the transport are thus simplified compared to known edge plaster profiles, since the edge plaster profile according to the invention in its folded form requires significantly less space than the usual, angular edge plaster profiles. In the case of the edge plaster profile according to the invention, the desired angle can then, for example, only be set and determined directly before use, ie on the construction site, by appropriately opening the edge plaster profile. The minimum adjustable angle between the profile legs can preferably be between 0 ° and 30 °, advantageously between 0 ° and 20 °, in particular between 0 ° and in the case of an approximate collapse by the hinge 10 °. When fully collapsed, the minimum angle is essentially 0 ° or exactly 0 °.

Another aspect of the invention relates to the use of a profile leg according to the invention for producing an edge plaster profile. For this purpose, the profile leg is divided between the corner longitudinal edge and the distal longitudinal edge and the hinge axis is inserted into the hinge socket in order to produce the edge trim profile.

The invention also relates to the use of an edge plaster profile according to the invention, in which the edge plaster profile is stored and / or transported folded up, is unfolded before being attached to an edge to be plastered until a desired angle between the profile legs is set and determined, and then in the unfolded state the edge is created.

Further developments of the invention are given in the dependent claims, the description and the accompanying drawings.

As an alternative to the invention, the hinge can in principle be formed by a plastically deformable area of the connecting section, in particular by a plastically deformable plastic. This means that after the desired angle has been set, it is automatically established, ie retained. It is thus prevented that the set angle changes without external influence, for example due to an elasticity of the connecting section and possibly the plastic. The plastically deformable plastic can preferably be polyethylene (PE), polypropylene (PP), polyurethane (PU), polyamide (PA) or polyvinyl chloride (PVC), preferably PVC, very particularly preferably soft PVC. The leg surfaces, on the other hand, can preferably be formed from a hard plastic so that the edge trim profile receives a corresponding rigidity. For the production of the leg surfaces, polyethylene (PE), polypropylene (PP), polyurethane (PU), polyamide (PA) or polyvinyl chloride (PVC) can be used, particularly preferably PVC, very particularly preferably a rigid PVC. The hinge is advantageously made of soft PVC, while the leg surfaces are made of hard PVC. The hinge is preferably designed as a film hinge. Such a film hinge can be produced simply by injection molding, extrusion or coextrusion, for example, without having to resort to further processing steps, so that production costs can be reduced. In addition, it is preferred if the leg surfaces and the connecting sections are produced jointly by coextrusion. This allows leg surfaces and connecting sections to be produced simultaneously in one work step, even if they have different materials.

According to one embodiment of the invention, the first profile leg has a hinge axis on the connection section, while the second profile leg has a hinge bush on the connection section. The hinge bushing of the second profile leg engages around the hinge axis of the first profile leg in a form-fitting manner. This forms a hinge without having to resort to different materials for the leg surfaces and the connecting sections. This makes it possible to carry out the production method in a particularly simple manner, which contributes to a reduction in production costs.

Particularly preferably, a non-positive connection is formed between the hinge bushing of the second profile leg and the hinge axis of the first profile leg in order to define an angle formed between the two profile legs. The non-positive connection can be achieved, for example, in that the hinge axis is dimensioned such that it is clamped in the hinge bushing, so that a frictional force between Hinge axis and hinge bush occurs. To set the angle between the profile legs, the frictional force between the hinge axis and the hinge bushing must then be overcome so that the frictional force determines the angle set between the profile legs.

It is preferred that the hinge axis of the first profile leg is clipped or pushed into the hinge socket of the second profile leg. In this way, the two profile legs can be produced independently of one another and then joined together to form the edge plaster profile.

The first profile leg preferably has a hinge bush on the distal longitudinal edge and the second profile leg has a hinge axis on the distal longitudinal edge.

The hinge axis preferably has a first latching means, in particular on its outside, and the hinge bushing preferably has a second latching means on an inside of the bushing, which can latch with the first latching means when the hinge axis is arranged in the hinge bushing. This creates a kind of ratchet grid through which, when the two profile legs are pivoted towards one another, the angle set is fixed and at the same time it is prevented from being inadvertently changed after the angle has been set.

Furthermore, it is preferred that the corner longitudinal edge of the first profile leg is at least substantially identical to the distal longitudinal edge of the second profile leg and / or that the corner longitudinal edge of the second profile leg is at least substantially identical to the distal longitudinal edge of the first profile leg is trained. Particularly preferably, the first profile leg and the second profile leg are at least essentially identical. This reduces production and inventory costs, as is the case for both Profile legs each the same tools or machines can be used for production. There is also no need to keep two different profile legs. Two identical profile legs can simply be used to produce the edge trim profile, one of the profile legs being rotated 180 ° around its longitudinal axis so that the hinge bushing of one profile leg comes to lie adjacent to the hinge axis of the other profile leg. The two profile legs can then be connected to one another via the hinge axis and the hinge bushing.

Furthermore, it is preferred that in a completely folded state of the edge trim profile, the hinge axis of the first profile leg is arranged in the hinge socket of the second profile leg and the hinge axis of the second profile leg is arranged in the hinge socket of the first profile leg. As a result, the edge trim profile can be stored and / or transported in a space-saving manner as a set with two profile legs, with the interlocking of the hinge axes and hinge bushes on the corner and distal longitudinal edges preventing the edge trim profile from being opened unintentionally.

Regardless of the design of the hinge, the leg surfaces of the first and second profile legs preferably have at least one opening. This makes it possible to quickly and easily fix the edge plaster profile with a mortar, for example in the form of so-called plaster lumps, on the wall to be plastered. It is particularly preferable for the leg surfaces of the first and second profile legs to have a large number of openings. Very particularly preferably, the openings form a hole pattern which has a honeycomb structure. The openings make it possible to further reduce the cost of materials for the production of the edge trim profile, which is also associated with a reduction in weight. A honeycomb structure formed by a hole pattern enables particularly light profile legs with sufficient flexural strength to be produced with very little material expenditure. The edge trim profile preferably has a fixing means by which the angle set and fixed by the hinge can be permanently fixed. This makes it possible, for example, to set several edge plaster profiles to the desired angle and then install them one after the other without the risk of the preset edge plaster profiles being inadvertently adjusted if, for example, undesired external forces act on the edge plaster profile inadvertently.

The fixing means is preferably in the form of a bar-shaped spacer, in particular, the spacer having at least one holding section which can be coupled to a mating section formed on one of the profile legs for fixing the set angle. The mating section is particularly preferably designed as a fixing opening formed in the profile leg. Such a counter-section designed as a fixing opening can be produced particularly easily, for example by injection molding, without an additional work step being necessary for this. Alternatively, such a fixing opening can be punched out of the leg surfaces at any point as required.

According to a particularly preferred variant, the fixing means is fixed at one end but can be pivoted, in particular with a film hinge, attached to one of the profile legs. This makes it possible to produce the fixing means together with the profile leg, for example by an injection molding process. In another particularly preferred variant, the fixing means has at least two opposing holding sections.

The fixing means is preferably designed as a break-out fixing means that is integrated in at least one of the leg surfaces and is secured, for example, by webs in the leg surface. This allows the fixing agent to be used during manufacture integrate the leg surface in this, so that the fixing means does not have to be kept as a separate component. The securing of the fixation means in the thigh area prevents it from being lost or unintentionally flipping out of the thigh area and being damaged in the process.

To set an angle between two profile legs of an edge plaster profile according to the invention, an adjustment gauge can be used which comprises a flat base body with an adjustment side, with at least one fixation receptacle and at least one adjustment receptacle being provided on the adjustment side, the fixation receptacle for receiving a first profile leg and the adjustment receptacle are designed to receive a second profile leg of the edge plastering profile, wherein the at least one fixing receptacle has an undercut acting in the direction of the adjustment side for the first profile leg of the edge plastering profile, which counteracts removal of a first profile leg received in the fixing receptacle in the direction of the adjustment side, and at least an adjustment receptacle is designed so that the second profile leg of the edge trim profile can be inserted into it. The undercut of the fixation receptacle is formed by a projection extending away from the at least one adjustment receptacle, which projection is designed such that the first profile leg of the edge trim profile can be hooked onto it.

A handle side is preferably provided on a side of the flat base body opposite the adjustment side, a handle surface being spanned between the adjustment side and the handle side.

The adjustment gauge can be used to set a constant angle between the profile legs over the entire length of the edge plaster profile.

Furthermore, in the case of the adjustment gauge, a handle side can be provided opposite the adjustment side, the adjustment side and the handle side spanning a gripping surface. The flat base body of the adjustment gauge preferably has a thickness which extends perpendicular to the grip surface and which is smaller than a length of the grip side. The thickness is particularly preferably less than or equal to 5.0 cm, most preferably less than or equal to 3.0 cm. The thickness between 0.3 cm and 1 cm, in particular approx. 0.5 cm, is particularly preferred. An adjustment gauge with such a thickness can be gripped particularly well and still has the necessary stability to be guided over the length of the edge plaster profile and thereby set the desired angle between the two profile legs of the edge plaster profile.

The base body can have a passage opening which is designed as an opening in the base body formed on the handle side.

The at least one adjustment receptacle of the adjustment gauge is preferably designed to be open to the adjustment side via a receptacle opening through which the second profile leg can be inserted into the at least one adjustment receptacle. When the free end of the second profile leg is inserted into the adjustment receptacle, the remaining part of the second profile leg thus protrudes from the receiving opening. The at least one adjustment receptacle can in particular be designed in such a way that it widens in the direction of the receptacle opening. This can be achieved, for example, by a rounded receiving opening of the adjustment receptacle. This makes it easier to insert the second profile leg. It can also be preferred to design the at least one fixation receptacle in a similar manner so that it is in particular an im Cross-section widened free end of the first profile leg does not engage when it is received in the at least one fixing receptacle. This makes it possible that the first profile leg can be inserted into the fixation receptacle in the direction of the adjustment side, ie the adjustment gauge can be slipped onto the first and second profile legs transversely to the longitudinal direction of the edge plaster profile.

Furthermore, the receiving opening of the at least one adjustment receptacle of the adjustment gauge can be designed such that the at least one adjustment receptacle narrows in the direction of the receiving opening. In order to enable the second profile leg to be inserted into the adjustment receptacle, the adjustment gauge with the adjustment receptacle can be pushed onto the second profile leg from the end face of the edge plaster profile in the longitudinal direction of the edge plaster profile. As a result of the narrowing of the receiving opening, a free end of the second profile leg, in particular with a widened cross section, can be encompassed by the adjustment receptacle, so that the second profile leg cannot be moved out of the adjustment receptacle in the direction of the adjustment side. After the adjustment fixture has been pushed onto the second profile leg, the adjustment gauge can then be moved along the longitudinal direction of the edge trim profile without the second profile leg being inadvertently movable out of the adjustment fixture of the adjustment gauge through the accommodation opening in the direction of the adjustment side.

It can also be preferred to design the at least one fixation receptacle in a similar manner so that it encompasses, in particular, a free end of the first profile leg with a widened cross section when this is received in the at least one fixation receptacle. This reliably prevents the first profile leg from being inadvertently moved out of the fixing receptacle of the adjustment gauge through a receiving opening in the fixing receptacle after the fixing receptacle has been pushed onto the first profile leg.

At least one, but not more than ten, adjustment receptacles are preferably provided on the adjustment side of the adjustment gauge. It is particularly preferred if the adjustment gauge has 1, 2, 3 or 4 adjustment receptacles.

In addition, at least one, but not more than ten, fixation receptacles are preferably provided on the adjustment side of the adjustment gauge. It is particularly preferred if the adjustment gauge has 1, 2, 3 or 4 fixing receptacles.

When using the edge trim profile according to the invention, the desired angle between the profile legs is preferably set using the adjustment gauge by moving the adjustment gauge relative to the edge trim profile along a longitudinal direction of the edge trim profile, while the first profile leg is received in the fixing seat and the second profile leg in an adjustment seat is. In this way, a constant angle between the profile legs can be reliably set over the entire length of the edge plaster profile in a simple manner. The profile legs can be received in the fixation or adjustment receptacles by attaching the adjustment gauge to the profile legs transversely to the longitudinal direction of the edge plaster profile or by sliding the fixation and adjustment receptacles onto the respective profile legs parallel to the longitudinal direction.

The first and the second profile leg of the edge trim profile can in particular be inserted into one of the fixation or adjustment receptacles of the adjustment gauge by inserting the first and second profile legs into the corresponding fixation or adjustment receptacle in the direction of the adjustment side. This procedure is particularly suitable for inserting the first and second profile legs when the receiving opening of the at least one adjustment receptacle of the adjustment gauge is designed such that the at least one adjustment receptacle is located widened in the direction of the receiving opening and the at least one fixing receptacle does not encompass a free end of the first profile leg with a widened cross section when this is received in the at least one fixing receptacle.

It is particularly preferred to push the adjustment gauge onto the first and second profile legs from the end face of the edge plaster profile in the longitudinal direction of the edge plaster profile. Sliding on from the front side is particularly advantageous if the receiving opening of the at least one adjustment receptacle of the adjustment gauge is designed so that the at least one adjustment receptacle narrows in the direction of the receiving opening, i.e. the adjustment receptacle is designed in such a way that it encompasses in particular a free end of the second profile leg that is broadened in cross section when this is received in the at least one fixing receptacle and / or the at least one fixing receptacle is designed in a similar way so that it in particular has a widened cross section engages around the free end of the first profile leg when it is received in the at least one fixing receptacle.

In the Figs. 1 to 4 a section of an edge trim profile 1 according to a not claimed first embodiment alternative to the invention is shown, which extends along a longitudinal direction L. The edge trim profile 1 is preferably made of plastic, in particular PVC. A first profile leg 2 is in Fig. 1 shown. It has a leg surface 3 which is delimited by a corner longitudinal edge 4 and a distal longitudinal edge 5, which extend in the longitudinal direction L, and is pierced by a multiplicity of perforations 7. The openings 7 here form a honeycomb structure. On the distal longitudinal edge 5 there is provided a flange 20 which extends in particular over the entire length of the first profile leg 2 and by means of which a stiffening of the profile leg 2 is achieved. On the side of the corner longitudinal edge 4, the first profile leg 2 has a connecting section 6, via which it is connected to a second profile leg 8. The second profile leg 8 can essentially be identical to the first profile leg 2 and is in Fig. 1 not visible because it is covered by the first profile leg 2.

Like in particular from Fig. 2 As can be seen, the first profile leg 2 and the second profile leg 8 are connected via their connecting sections 6 at their corner longitudinal edges 4 by a hinge 9. Due to the hinge 9, the two profile legs 2, 8 can be folded apart. The hinge 9 is formed by a plastic material, the material properties of which ensure that the two profile legs 2, 8 of the edge plaster profile 1 can not only be set to an angle, but can also be fixed. This means that the set angle is held by the hinge 9 without the action of external force. The edge trim profile 1 can then be arranged on an edge 22 formed by two converging walls 21, so that the two distal longitudinal edges 5 of the profile legs 2, 8 come to rest against the walls 21, as shown, for example, in FIG Fig. 3 is shown.

As in Fig. 4 is illustrated, different plaster thicknesses can be applied to the walls 21 by different angles of the edge plaster profile 1. Thus, a larger angle between the two profile legs 2, 8 leads to a lower plaster thickness and a smaller angle between the two profile legs 2, 8 to an increased plaster thickness. By applying the edge plaster profile 1 asymmetrically to the edge 22, ie if the distal longitudinal edge 5 of the first profile leg 2 has a different distance from the edge 22 than the distal longitudinal edge 5 of the second profile leg 8, the two converging sides of the Walls to be plastered can be made of 21 different plaster thicknesses.

As in Fig. 5 As shown, the hinge 9 can comprise a hollow chamber 24 between the two profile legs 2, 8. A spring effect is achieved by the hollow chamber 24, which when increasing the angle, for example when pressing on the edge 22, causes a counterforce to reduce the angle. Thus, a restoring force is generated to smaller angles, so that the edge plaster profile 1 does not push them apart when plastering with lumps of plaster, but rather clamps them.

The FIGS. 6a to 13 relate to different configurations of different embodiments of an edge plaster profile 1 according to the invention or a profile leg 2 according to the invention. Basically identical or similar elements are given the same reference numerals as in FIGS Figs. 1 to 5 designated. A dividing aid is not shown in the figures. In Figure 6a a first profile leg 2 of an edge plaster profile 1 is shown in perspective. The first profile leg 2 has a leg surface 3 which is delimited by a corner longitudinal edge 4 and a distal longitudinal edge 5, which extend in the longitudinal direction L, and is pierced by a multiplicity of openings 7. On the side of the corner longitudinal edge 4, the first profile leg 2 has a connecting section 6 on which is provided with a hinge axis 10.

As in Fig. 7 shown, the first profile leg 2 together with an identically designed second profile leg 8 forms an edge plaster profile according to the invention. To connect the two profile legs 2, 8, the connecting section 6 of the second profile leg 8 has a hinge bush 11. Since the hinge bushing 11 of the second profile leg 8 engages around the hinge axis 10 of the first profile leg 10, a hinge 9 is formed. According to the invention, the hinge 9 allows the angle between the two profile legs 2, 8 to be set and fixed, as will be described in more detail below. The hinge bush 11 and the hinge axis 10 are dimensioned in such a way that the hinge axis 10 is clamped in the hinge bush 11, i.e. a non-positive connection is formed between the hinge axis 10 and the hinge bush 11, the frictional connection being between the profile legs 2, 8 the set angle. Further latching means 12, 14 are not provided on the hinge axis 10 and on the hinge bush 11.

In the Figures 8a and 8b enlarged views of the hinge bushing 11 and the hinge axis 10 are shown. A first latching means 12 is provided on the outside of the hinge axis 10, which can engage with a second latching means 14, which is arranged on the inner side 13 of the hinge bushing 11, when the hinge axis 10 is arranged in the hinge bushing 11. This enables the set angle to be specified so that unintentional adjustment of the set angle is prevented. As a result, several edge plaster profiles 1 can initially be set as desired and then installed one after the other. The first latching means 12 is designed as a latching projection which can in particular extend over the entire length of the hinge axis 10. In principle, the locking projection could also be designed to be interrupted over its length. In addition, several latching projections can in principle also be provided, as in FIG Figure 8d shown. The second latching means 14 comprises, as in FIG Figures 8a and 8c shown, a plurality of latching recesses, which preferably extend over the entire length of the hinge sleeve 11. In the circumferential direction, the locking recesses can be, as in Figure 8a shown, only over a partial angular range of the hinge bush 11 or, as in FIG Figure 8c shown, extend over the entire angular range of the hinge bush 11. In principle, the latching recesses can also be designed to be interrupted, adapted to the latching projection. It is also conceivable that, in a corresponding manner, the first latching means 12 are designed as a latching recess and the second latching means 14 as a latching projection, as shown in FIG Figures 8e and 8f is shown.

In Fig. 9 three cross-sections of an edge plaster profile 1 are shown, which is set to three different angles. The edge plaster profile 1, whose cross-sections in Fig. 9 shown comprises a hinge bushing 11 according to FIG Figure 8c on the corner long edge 4 of the second profile leg 8 and a hinge axis 10 according to Figure 8d on the corner longitudinal edge 4 of the first profile leg 2. Similar cross-sections as in Fig. 9 are in Fig. 10 shown for an edge plaster profile 1, the second profile leg 8 on the corner longitudinal edge 4 a hinge bush 11 according to Figure 8e and its first profile leg at the corner longitudinal edge 4 has a hinge axis 10 according to Fig. 8f having.

Regardless of the specific shape of the hinge bush and the hinge axis, the first profile leg 2 preferably has, in addition to the hinge axis 10 provided on the connecting section 6, a hinge bush 11 which runs along the distal longitudinal edge 5. At the same time, the second profile leg 8 can have a hinge axis 10 along its distal longitudinal edge 5, in addition to the hinge bushing 11 running along its corner longitudinal edge 4. In this case, in a folded state of the edge trim profile 1, as in FIG Fig. 11 shown, the hinge sleeve 11 of the second profile leg 8 encompass the hinge axis 10 of the first profile leg 2 on the side of the corner longitudinal edge 4 in a form-fitting manner, while on the side of the distal longitudinal edge 5, the hinge axis 10 of the second profile leg 8 from the hinge sleeve 11 of the first profile leg 2 is positively encompassed. This prevents the edge trim profile 1 from being able to unfold unintentionally, which is particularly advantageous during transport and storage. Basically, the edge trim profile 1 can also be designed so that on the side of the distal longitudinal edge 5, the hinge axis 10 of the second profile leg 8 is not positively encompassed by the hinge sleeve 11 of the first profile leg 2, as shown in FIG Fig. 12 is shown. As a result, the edge trim profile 1 can be set and fixed to an angle very quickly without the hinge axis 10 of the second profile leg 8 having to be moved out of the hinge bush 11 of the first profile leg 2 beforehand. Regardless of the design of the connecting sections 6, at least one fixing means 15 can be provided in the leg surfaces 3, which is in particular designed as a web-shaped spacer and has a holding section 16. Different variants for such fixing means 15 are in the Figure 6a and 6b shown. By means of the holding section 16, the fixing means 15 for fixing the set angle can be coupled to a mating section 17 formed on one of the profile legs 2, 8, for example as shown in FIG Fig. 7 is shown. In this way, the angle set and set by the hinge 9 is additionally fixed, which effectively prevents the set angle from being inadvertently adjusted by forces inadvertently acting on the edge trim profile 1.

In the case of the Figure 6a As shown in the variant shown, the fixing means 15, which is preferably T-shaped, is connected to the first profile leg 2 by a film hinge 18. The fixing means 15 can thus be folded out of the leg surface 3 in order to be coupled with its holding section 16 to the preferably T-shaped counter-section 17 formed on the second profile leg 8. The free end of the pivoted fixing means 15 is first passed through an opening section of the counter-section 17 extending in the longitudinal direction of the second profile leg 8 and then pivoted into an opening section extending transversely to the longitudinal extension of the second profile leg 8. The holding section 16 and the mating section 17 are designed in such a way that, once the coupling has been carried out, it is not possible to enlarge or reduce the angle set between the profile legs 2, 8 without explicitly releasing the coupling. For this purpose, the fixing means 15 has lateral projections 23 which, after coupling, engage behind the opening edges of the mating section 17.

Another variant that appears in Figure 6b is shown, provides that the fixing means 15 is initially fixed with webs 19 in the leg surface 3. The fixative 15 has at least two opposing holding sections 16, with which a mating section 17 of the first profile leg 2 and a mating section 17 of the second profile leg 8 can be coupled after the fixing means 15 has been broken out of the leg surface and the edge trim profile 1 has been set to a certain angle. The coupling takes place in a manner similar to that described above, in that the two free ends of the fixing means 15 are first inserted into the opening sections of the counter-section 17 that run in the longitudinal direction of the profile legs 2, 8. Subsequently, the preferably double-T-shaped fixing means 15 is rotated by 90 ° about its longitudinal axis, so that corresponding lateral projections 23 engage behind the opening edges of the mating section 17. Both in the Figure 6a and 6b In the variants shown, the holding sections 16 comprise a plurality of lateral projections 23 in order to enable different set angles to be fixed. In addition, it can be advantageous if a plurality of fixing means 15 and counter-sections 17 are provided over the longitudinal direction L. This makes it easy to achieve stabilization over the entire length of the edge trim profile 1.

At the in Fig. 13 A plurality of securing means 25, which prevent a hinge axis 10 arranged in the hinge bushing 11 from being displaced in the longitudinal direction L, are provided along the inside of the bushing 14. In particular, corresponding counter-locking means can also be provided on the outside of the hinge axis 10. As a result, the two profile legs 2, 8 are secured in such a way that they do not move relative to one another in the longitudinal direction L when the edge plaster profile is erected, for example. The securing means 25 as well as the counter-locking means can for example be designed as transverse grooves or projections or as corrugations or the like.

In the Figures 14a to 14d side views of a set of an edge plaster profile 1 and an adjusting gauge 26 are shown schematically. To get the overview true, are in the Figures 14a to 14d only the reference numerals of the Katenputzprofils 1 necessary for the explanation of the adjustment gauge 26 are shown. It goes without saying, however, that in principle each of the Figs. 6 to 13 edge plaster profiles 1 described with the in the Figures 14a to 14d Adjustment gauge 26 shown is adjustable to an angle between the profile legs 2, 8. The adjustment gauge 26 for setting an angle between two profile legs 2, 8 of an edge plaster profile 1 comprises a flat base body 27 with an adjustment side 28. A handle side 29 is arranged opposite the adjustment side 28. A gripping surface 30 is stretched between the adjustment side 28 and the grip side 29. On the adjustment side 28, a fixing receptacle 31 and four adjustment receptacles 32 are provided, in which Figures 14a to 14d A first profile leg 2 with a hinge bush 11 formed on the distal longitudinal edge 5 of the first profile leg 2 and a second profile leg 8 of the edge plaster profile 1 are inserted in one of the adjustment seats 32. On the fixing receptacle 31, a projection 33 extending away from the adjustment receptacles 32 is formed, which forms an undercut 33a for the first profile leg 2 of the edge trim profile 1 that acts in the direction of the adjustment side 28, on which the first profile leg 2 of the edge trim profile 1 and the one on the The hinge bush 11 formed in the distal longitudinal edge 5 is hooked, so that a removal of a first profile leg 2 received in the fixing receptacle 31 in the direction of the adjustment side 28 is counteracted. In Figure 14a the second profile leg of the edge plaster profile 1 is inserted into the adjustment receptacle 32 furthest away from the fixing receptacle 31, whereby a large angle is formed between the profile legs 2, 8. A smaller angle can be set between the profile legs 2, 8 by inserting the second profile leg 8 into one of the other three adjustment receptacles 32 ( Figures 14b, c, d ). The adjustment receptacles 32 have a receptacle opening 34 which is open to the adjustment side 29 and on which roundings 35 are formed.

The Figures 14a to 14d show how an edge plaster profile 1 can be set to four different angles with the adjustment gauge 26, whereby in turn four different plaster thicknesses can be implemented without having to resort to differently designed edge plaster profiles 1.

In the Fig. 15 shown perspective view of the adjustment gauge 26 of Figures 14a to 14d shows that the flat base body 27 has a thickness d extending perpendicularly to the grip surface 30, which is smaller than the length w of the grip side 29. On the grip surface 30, labels 36 are assigned to the four adjustment receptacles 32 which indicate the plaster thickness for which the edge plaster profile 1 is to be used or which angle is set between the profile legs 2, 8.

In the case of the Fig. 16 An alternative embodiment of an adjustment gauge 26, shown in perspective, is formed on the adjustment side 28 with four fixing receptacles 31 and four adjustment receptacles 32. The adjustment receptacles 32 narrow in the direction of the adjustment side 28, so that a second profile leg 8 of an edge plaster profile 1 (in Fig. 16 not shown) cannot be moved in the direction of the adjustment side 28 through the receiving opening 34 out of the adjustment receptacle 32 in which it is received. On each of the fixing receptacles 31, projections 33 are provided, on which the first profile leg 2 of the edge trim profile 1 with a hinge bush 11 formed on the distal longitudinal edge 5 can be hooked. At the in Fig. 16 The illustrated embodiment, inscriptions 36 are also assigned to the four adjustment receptacles 32 on the grip surface 30, which indicate the plaster thickness for which the edge plaster profile 1 or which angle between the profile legs 2, 8 is set. Further inscriptions 36 are assigned to the four fixing receptacles 31, which also indicate the plaster thickness for which the edge plaster profile 1 or which angle between the profile legs 2, 8 is set. Each adjustment receptacle 32 with a first inscription 36 is assigned a fixation receptacle 31 with the same inscription. The flat base body 27 has a perpendicular to the grip surface 30 extending thickness d, which is smaller than the length w of the grip side 29. On the grip surface 30 of the base body 27, a penetration opening 37 is formed, which represents an opening through the base body 27.

To set a desired angle between the profile legs 2, 8, the edge plaster profile 1 is first opened and the first profile leg 2 is inserted into the fixing receptacle 31 of the adjustment gauge 26 and hooked onto the projection 33, for example with one on the distal longitudinal edge 5 of the first profile leg 2 formed hinge bush 11. The second profile leg 8 is inserted into one of the adjustment receptacles 32 of the adjustment gauge 26, whereby the angle between the profile legs 2, 8 is determined, the insertion of the second profile leg 8 is facilitated by the rounded portions 35 of the openings 34. Depending on which of the adjustment receptacles 32 the second profile leg 8 is used in, a different angle is set between the profile legs 2, 8. When the first profile leg 2 is received in the fixation receptacle 31 and the second profile leg 8 in one of the adjustment receptacles 32, the adjustment gauge 26 is moved along the longitudinal direction L of the edge trim profile 1, which reliably moves along the entire length of the edge trim profile 1 through the distance from Fixing mount 31 and adjustment mount 32 can be set at specified angles. For easier handling, the Fig. 16 The adjustment gauge 26 shown has a reach-through opening 37 into which a user can reach in order to move the adjustment gauge along the longitudinal direction L of the edge trim profile 1 after inserting the first profile leg 2 into one of the fixing receptacles 31 and the second profile leg 8 into one of the adjustment receptacles 32 Has.

It is also possible to have a profile leg 2, as in the Figure 6a and 6b shown to be divided in the longitudinal direction L between the corner longitudinal edge 4 and the distal longitudinal edge 5, and the hinge axis 10, which runs along the corner longitudinal edge 4 in the along the distal longitudinal edge 5 extending hinge bushing 11 to form an edge trim profile 1 with two profile legs 2, 8, which can then be set to a desired angle between the profile legs 2, 8, as described above.
