[0002] Corner connector unit for a frame unit of a frame device, module unit for a frame unit of a frame device, frame device and protective system

[0003] The present invention relates to a corner connector unit for a frame unit of a frame device, a module unit for a frame unit of a frame device, a frame device and a protection system.

[0004] Frame devices are known from the prior art. Typically, frame devices known from the prior art comprise several frame units.

[0005] For example, several frame units of the same length are manufactured and delivered to a user of the frame device. The user then determines the desired length of each frame unit by measuring an opening into which the frame device is to be inserted, or which the frame device or a protective device attached to the frame device is to cover. Next, the user cuts each frame unit to the desired length by separating the appropriate sections.

[0006] In another example, frame units are manufactured, each comprising two telescopically sliding sections, and delivered to the user of the frame device. The user then determines the desired length of each frame unit by measuring an opening into which the frame device is to be inserted, or which is to cover the frame device or a protective device attached to the frame device. Next, the user sets the desired length for each frame unit by sliding the telescopically sliding sections relative to each other.

[0007] In general, it is desirable that differently designed frame devices can be provided in a particularly simple way.

[0008] It is therefore the object of the present invention to provide differently designed frame devices in a particularly simple manner. According to a first aspect of the invention, this object is achieved by a corner connector unit with the features of claim 1.

[0009] The corner connector unit is configured for a frame unit of a frame device. The corner connector unit has a first connection section with which the

[0010] The corner connector unit can be connected to a second connection section of a first module unit, and a second connection section is provided with which the corner connector unit can be connected to a first connection section of a second module unit. Furthermore, the first connection section of the corner connector unit and the first connection section of the second module unit are identical in construction, as are the second connection section of the corner connector unit and the second connection section of the first module unit. Additionally, the first connection section of the corner connector unit has a first contact surface extending along a first plane, and the second connection section of the corner connector unit has a second contact surface extending along a second plane that intersects the first plane.Furthermore, the first connecting section of the corner connector unit and the second connecting section of the corner connector unit are designed such that the first connecting section of the corner connector unit can be connected to the second connecting section of the first module unit, and the second connecting section of the corner connector unit can be connected to the first connecting section of the second module unit, such that a direction of extension of the first module unit, along which the first module unit extends from a first connecting section to the second connecting section, and a direction of extension of the second module unit, along which the second module unit extends from the first connecting section to a second connecting section, run along two straight lines perpendicular to each other.Furthermore, the corner connector unit has a fastening section that extends from the first level to the second level and to which a first section of a protective device can be attached.

[0011] As already described, the corner connector unit has the first connection section, with which the corner connector unit can be connected to the second connection section of the first module unit, and the second connection section, with which the corner connector unit can be connected to the first connection section of the second module unit.Because the corner connector unit can be connected to the first connecting section of the first module unit via the first connecting section, and the corner connector unit can be connected to the first connecting section of the second module unit via the second connecting section, it is ensured that the corner connector unit, together with a module unit (e.g., the first module unit), can form a section of the frame unit of the frame device, and can be connected to another module unit (e.g., the second module unit), which forms a section of another frame unit of the frame device, so that the corner connector unit can connect two frame units of the frame device together.

[0012] As previously described, the first connection section of the corner connector unit and the first connection section of the second module unit are identical in construction, as are the second connection section of the corner connector unit and the second connection section of the first module unit. This identical construction of the first connection section of the corner connector unit and the first connection section of the second module unit, as well as the second connection section of the corner connector unit and the second connection section of the first module unit, ensures that the corner connector unit is compatible with module units of a system with identically constructed modules and can be integrated into that system.

[0013] As also previously described, the first connecting section of the corner connector unit has the first contact surface that extends along the first plane, and the second connecting section of the corner connector unit has the second contact surface that extends along the second plane that intersects the first plane.Because the first mounting surface extends along the first level, the first mounting surface provides an optimal mounting surface for a second mounting surface of a module unit, which extends along a second level relating to the module unit, so that in a connected state of the corner connector unit and the module unit a particularly robust connection is established between the corner connector unit and the module unit, especially against tilting of the module unit relative to the corner connector unit in the sense of pivoting the first connection section of the module unit perpendicular to an extension direction of the module unit around the second connection section of the module unit.Because the second mounting surface extends along the second level, the second mounting surface provides an optimal mounting surface for a first mounting surface of the module unit, which extends along a first level relating to the module unit, so that in a connected state of the corner connector unit and the module unit a particularly robust connection is established between the corner connector unit and the module unit, especially against tilting of the module unit relative to the corner connector unit in the sense of pivoting the second connection section of the module unit perpendicular to the extension direction of the module unit about the first connection section of the module unit.The fact that the first plane and the second plane intersect ensures that the first plane points in a first direction and the second plane points in a second direction, with the first direction and the second direction running along two perpendicular straight lines.

[0014] As previously described, the first and second connecting sections of the corner connector unit are designed such that the first connecting section of the corner connector unit can be connected to the second connecting section of the first module unit, and the second connecting section of the corner connector unit can be connected to the first connecting section of the second module unit, such that the extension direction of the first module unit, along which it extends from the first connecting section to the second connecting section, and the extension direction of the second module unit, along which it extends from the first connecting section to a second connecting section, run along two perpendicular straight lines. This ensures that,that the first connecting section of the corner connector unit and the second connecting section of the corner connector unit are designed such that the first connecting section of the corner connector unit can be connected to the second connecting section of the first module unit and the second connecting section of the corner connector unit can be connected to the first connecting section of the second module unit such that the direction of extension of the first module unit, along which the first module unit extends from the first connecting section to the second connecting section, and a direction of extension of the second module unit, along which the second module unit extends from the first connecting section to the second connecting section, run along two transverse straight lines, it is ensured that the corner connector unit connects two module units, namely the first module unit and the second module unit.two different frame units, namely the first module unit to a first frame unit and the second module unit to a second frame unit, can be connected to each other, wherein the two module units extend along two straight lines perpendicular to each other, along which one of the two frame units also extends. Thus, the first frame unit, which has the first module unit, can extend along a first straight line along which the extension direction of the first module unit runs, and the second frame unit, which has the second module unit, can extend along a second straight line along which the extension direction of the second module unit runs, with the first and second straight lines being perpendicular to each other. As also already described, the corner connector unit has the fastening section,which extends from the first level to the second level and to which a first section of a protective device can be attached. Because the corner connector unit has the mounting section extending from the first level to the second level, it is ensured that the mounting section extends along the entire length of the corner connector unit between two sections of the corner connector unit, to each of which a module unit can be attached. This allows for continuous mounting of the protective device within each frame unit and each frame fixture. The continuous mounting of the protective device to the corner connector unit ensures a particularly robust mechanical design of the protective system.

[0015] Using the corner connector unit according to the invention, a frame unit can be formed from the corner connector unit and several identically designed module units, which significantly simplifies the production of the frame unit. Furthermore, frame units of different lengths can be produced using the corner connector unit according to the invention and several identically designed module units. Additionally, different frame units can be connected to one another using the corner connector unit according to the invention, which significantly simplifies the overall construction of the frame device.

[0016] In summary, it can therefore be stated that with the help of the corner connector unit according to the invention, especially in combination with several identically designed module units, differently designed frame devices can be provided in a particularly simple way.

[0017] Preferably, the first connecting section of the corner connector unit has a plug-in projection, and the second connecting section of the corner connector unit has a plug-in recess. Because the first connecting section of the corner connector unit has the plug-in projection and the second connecting section has the plug-in recess, particularly simple connecting elements are provided for connecting the corner connector unit to the module units already described.

[0018] Preferably, the plug-in projection and the plug-in recess are dovetail-shaped. This dovetail design ensures a mechanically robust connection between the corner connector unit and one or more module units without the need for additional fasteners, making the connection of the corner connector unit to the module units particularly user-friendly.

[0019] In one embodiment, the corner connector unit has a third contact surface extending along a third plane that intersects both the first plane and the second plane, wherein the third contact surface is designed such that when the first section of the protective device is attached to the fastening section, a second section of the protective device can rest against the third contact surface.Because the corner connector unit has a third contact surface extending along the third plane, which intersects both the first and second planes, and the third contact surface is designed such that when the first section of the guard is attached to the mounting section, a second section of the guard can rest against the third contact surface, a spatial separation is ensured between the attachment of the first section of the guard to the mounting section and the placement of the second section of the guard on the third contact surface, so that in the attached state of the guard on the mounting section, the third contact surface can ensure an optimal shape of the guard.

[0020] In one embodiment, the fastening section has a contact surface and several projections extending away from the contact surface. Preferably, each projection extends away from the contact surface. The fact that the fastening section has the contact surface and several projections extending away from the contact surface ensures that the section of the protective device is secured against slippage relative to the corner connector unit and is generally secured against slippage parallel to the contact surface.

[0021] In one embodiment, a guide groove extends from the first level to the second level, at least partially between the first connecting section of the corner connector unit and the fastening section of the corner connector unit, and at least partially between the second connecting section of the corner connector unit and the fastening section of the corner connector unit. The guide groove enables a cutting tool to be guided particularly reliably along the corner connector unit, allowing the cutting tool to be guided along the edges of the corner connector unit in order to cut off a protruding area of ​​a guard blank, thus ensuring an optimally shaped edge area of ​​the guard manufactured from the guard blank.This is because the guide groove extends from the first level to the second level, at least partially, between the first connecting section of the corner connector unit and the fastening section of the.

[0022] Corner connector unit and at least sectionally between the second

[0023] Connecting section of the corner connector unit and the fastening section of the

[0024] The extended corner connector unit ensures that the guide groove runs along the entire length of the unit between two sections, each of which can accommodate a module. This allows for the continuous removal of the protruding section of the guard blank within each frame unit and frame fixture. This continuous removal of the protruding section of the guard blank at the corner connector unit ensures particularly user-friendly operation of the guard system. For example, the corner connector units and module units can first be connected, then the guard can be attached to the corner connector units and module units, and finally the protruding section of the guard blank can be removed. This eliminates the need to measure the guard to its actual required dimensions.This is because the guide groove is located at least partially between the first connecting section of the corner connector unit and the fastening section of the.

[0025] Corner connector unit and at least sectionally between the second connecting section of the corner connector unit and the fastening section of the

[0026] The extended corner connector unit ensures that connecting the corner connector unit to two module units can be done spatially separate from attaching the protective device to the corner connector unit. This spatial separation ensures that the first connection section, the second connection section, and the fastening section can be individually adapted for their intended function.

[0027] According to a second aspect of the invention, the aforementioned problem is solved by a modular unit with the features of claim 5. The modular unit is configured for a frame unit of a frame device. Furthermore, the modular unit extends from a first connection section, with which the modular unit can be connected to a second connection section of an identically constructed further modular unit or with which the modular unit can be connected to a second connection section of a corner connector unit according to the first aspect of the invention, along a direction of extension towards a second connection section, with which the modular unit can be connected to a first connection section of an identically constructed further modular unit or with which the modular unit can be connected to a first connection section of a corner connector unit according to the first aspect of the invention.Furthermore, the first connecting section of the module unit and the first connecting section of the corner connector unit are identical in construction, as are the second connecting section of the module unit and the second connecting section of the corner connector unit. Additionally, the first connecting section of the module unit has a first contact surface extending along a first plane, and the second connecting section of the module unit has a second contact surface extending along a second plane parallel to the first plane.Furthermore, the first and second connecting sections of the module unit are designed such that both the first connecting section of the module unit can be connected to the second connecting section of an identically constructed further module unit in such a way that the extension direction of the module unit and the extension direction of the further module unit run along the same straight line, and the second connecting section of the module unit can also be connected to the first connecting section of an identically constructed further module unit in such a way that the extension direction of the module unit and the extension direction of the further module unit run along the same straight line. In addition, the module unit has a mounting section that extends from the first level to the second level and to which a first section of a protective device can be attached.

[0028] As already described, the module unit extends from the first connection section, with which the module unit can be connected to a second connection section of an identically constructed further module unit or with which the module unit can be connected to a second connection section of a corner connector unit according to the first aspect of the invention, along the direction of extension towards the second connection section, with which the module unit can be connected to the first connection section of an identically constructed further module unit or with which the module unit can be connected to the first connection section of the corner connector unit according to the first aspect of the invention.The fact that the module unit can be connected to the second connection section of an identically constructed further module unit via the first connection section, or to the second connection section of the corner connector unit, and that the module unit can be connected to the first connection section of an identically constructed further module unit via the second connection section, or to the first connection section of the corner connector unit, ensures that each frame unit of the frame device can be constructed using corner connector units and identically constructed module units.

[0029] As previously described, the first connection section of the module unit and the first connection section of the corner connector unit are identical in construction, as are the second connection section of the module unit and the second connection section of the corner connector unit. This identical construction of the first connection section of the module unit and the first connection section of the corner connector unit, as well as the second connection section of the module unit and the second connection section of the corner connector unit, ensures that the module unit is compatible with both corner connector units and module units of a system with identically constructed modules and can be integrated into that system.

[0030] As already described, the first connecting section of the module unit has a first mounting surface extending along a first plane, and the second connecting section of the module unit has a second mounting surface extending along a second plane parallel to the first plane.Because the first mounting surface extends along the first level, the first mounting surface provides an optimal mounting surface for the second mounting surface of the corner connector unit, which extends along the second level relating to the corner connector unit, so that in a connected state of the corner connector unit and the module unit, a particularly robust connection is established between the corner connector unit and the module unit, especially against tilting of the module unit relative to the corner connector unit in the sense of pivoting the second connection section perpendicular to the direction of extension around the first connection section.Because the second mounting surface extends along the second level, the second mounting surface provides an optimal mounting surface for the first mounting surface of the corner connector unit, which extends along the first level relating to the corner connector unit, so that in a connected state of the corner connector unit and the module unit, a particularly robust connection is established between the corner connector unit and the module unit, especially against tilting of the module unit relative to the corner connector unit in the sense of pivoting the first connection section perpendicular to the direction of extension around the second connection section.By ensuring that the first plane relating to the module unit and the second plane relating to the module unit extend parallel to each other, it is ensured that the first plane points in a first direction and the second plane points in a second direction, with the first direction and the second direction running along the same straight line.

[0031] As previously described, the first and second connecting sections of the module unit are designed such that both the first and second connecting sections of the module unit can be connected to the second connecting section of an identically constructed further module unit in such a way that the extension direction of the module unit and the extension direction of the further module unit run along the same straight line, and the second connecting section of the module unit can also be connected to the first connecting section of an identically constructed further module unit in such a way that the extension direction of the module unit and the extension direction of the further module unit run along the same straight line. Because the first and second connecting sections of the module unit are designed in this way,that both the first connecting section of the module unit can be connected to the second connecting section of an identically constructed further module unit in such a way that the extension direction of the module unit and the extension direction of the further module unit run along the same straight line, and that the second connecting section of the module unit can be connected to the first connecting section of an identically constructed further module unit in such a way that the extension direction of the module unit and the extension direction of the further module unit run along the same straight line, it is ensured that each frame unit of the frame device, which is constructed at least partially using identically constructed module units, can be formed at least partially along one extension direction of the frame unit by the identically constructed and interconnected module units.the extension direction of the frame unit runs along the same straight line along which the extension directions of the module units also run.

[0032] As previously described, the module unit features a mounting section extending from the first level to the second level, to which the first section of a protective device can be attached. This mounting section, extending from the first to the second level, ensures that it runs along the entire length of the module unit between two sections. Each of these sections can accommodate a corner connector or a module unit, thus enabling continuous mounting of the protective device within each frame unit and frame fixture. This continuous mounting of the protective device to the module unit ensures a particularly robust mechanical design for the protective system.

[0033] Preferably, an identically constructed module unit or an identically constructed further module unit is constructed in the same way as the further module units or as the module unit itself. According to the present invention, the module units are therefore preferably identically constructed, which can also be described as identically designed. The fact that the module units are preferably identically constructed ensures that the module units can be manufactured particularly efficiently, since the module units can be produced, for example, using the same tool, such as an injection mold. The identically constructed further module unit, to whose second connecting section the first connecting section of the module unit can be connected or is connected in the connected state, can also be referred to as the first further module unit.The identically constructed additional module unit, whose first connecting section can be connected to the second connecting section of the module unit or is connected in the connected state, can also be referred to as the second additional module unit.

[0034] Preferably, the first connecting section of the module unit can be connected to the second connecting section of an identically constructed further module unit in such a way that the extension direction of the module unit and the extension direction of the further module unit run along the same straight line. Using such interconnected module units, frame units of different lengths can be produced. For example, the further module unit and the module unit can be module units of a frame unit, which can also be referred to as the first frame unit. The first frame unit and the second frame unit are preferably connected by means of corner connector units in such a way that the extension directions of the frame units run perpendicular to each other.

[0035] Using the modular unit according to the invention, a frame unit can be formed from several identically designed modular units and a corner connector unit, which significantly simplifies the production of the modular units and the frame unit. Furthermore, frame units of different lengths can be produced using the modular units according to the invention. In addition, different frame units can be connected to one another using the modular units according to the invention, particularly in combination with a corner connector unit, which significantly simplifies the overall construction of the frame device.

[0036] In summary, it can therefore be stated that differently designed frame devices can be provided in a particularly simple way using the modular unit according to the invention.

[0037] Preferably, the first connecting section of the module unit has a plug-in projection, and the second connecting section of the module unit has a plug-in recess. Because the first connecting section of the module unit has the plug-in projection and the second connecting section of the module unit has the plug-in recess, particularly simple connecting elements are provided for connecting the module unit to other identically constructed module units and to a corner connector unit already described.

[0038] Preferably, the plug-in projection and the plug-in recess are dovetail-shaped. This dovetail design ensures a mechanically robust connection between the module unit and other module units, as well as a corner connector unit, without the need for additional fasteners, making the connection of the module units and the corner connector units particularly user-friendly.

[0039] The features, technical effects and / or advantages described in connection with the corner connector unit according to the first aspect of the invention also apply, at least analogously, to the module unit according to the second aspect of the invention, and the features, technical effects and / or advantages described in connection with the module unit according to the second aspect of the invention also apply, at least analogously, to the corner connector unit according to the first aspect of the invention, so that a corresponding repetition is omitted here.

[0040] In one embodiment, the module unit has a third contact surface extending along a third plane that intersects both the first plane and the second plane, wherein the third contact surface is designed such that when the first section of the protective device is attached to the mounting section, a second section of the protective device can rest against the third contact surface.Because the module unit has a third contact surface extending along a third plane that intersects both the first and second planes, and because the third contact surface is designed such that when the first section of the guard is attached to the mounting section, a second section of the guard can rest against the third contact surface, spatial separation is ensured between the attachment of the first section of the guard to the mounting section and the contact of the second section of the guard against the third contact surface. This ensures that, when the guard is attached to the mounting section, the third contact surface can maintain an optimal shape for the guard. In one embodiment, the mounting section has a contact surface and several projections extending away from the contact surface.Preferably, each of the multiple projections extends away from the mounting surface. Because the fastening section comprises the mounting surface and the multiple projections extending away from the mounting surface, it is ensured that the section of the protective device is secured against slippage relative to the module unit and is generally secured against slippage parallel to the mounting surface.

[0041] In one embodiment, a guide groove extends from the first level to the second level, at least partially between the first connecting section of the module unit and the mounting section of the module unit, and at least partially between the second connecting section of the module unit and the mounting section of the module unit. The guide groove allows a cutting tool to be guided particularly reliably along the module unit, enabling it to be guided along the edges of the module unit to remove a protruding area of ​​a guard blank, thus ensuring an optimally shaped edge area of ​​the guard manufactured from the guard blank.By extending the guide groove at least partially between the first connecting section of the module unit and the mounting section of the module unit, and at least partially between the second connecting section of the module unit and the mounting section of the module unit, from the first level to the second level, it is ensured that the guide groove extends along the entire module unit between two sections of the module unit, to which a corner connector unit or a module unit can be attached, thus enabling continuous separation of the protruding area of ​​the protective device blank within each frame unit and each frame device.The continuous removal of the protruding area of ​​the protective device blank at the module unit ensures particularly user-friendly use of the protective system, since, for example, the corner connector units and module units can first be connected together, then the protective device can be attached to the corner connector units and module units, and subsequently the protruding area of ​​the protective device blank can be cut off, thus eliminating the need to measure the actual dimensions of the protective device.Because the guide groove extends at least partially between the first connecting section of the module unit and the mounting section of the module unit, and at least partially between the second connecting section of the module unit and the mounting section of the module unit, it is ensured that connecting the module unit to a corner connector unit and to another module unit, or to two module units, can be done spatially separate from attaching the protective device to the module unit. This spatial separation ensures that the first connecting section, the second connecting section, and the mounting section can be individually adapted for their intended function.

[0042] According to a third aspect of the invention, the aforementioned problem is solved by a frame device with the features of claim 9. The frame device comprises several frame units. Each frame unit of the several frame units comprises a corner connector unit according to the first aspect of the invention and a module unit according to the second aspect of the invention. Preferably, the corner connector unit and the module unit are connected to each other in each frame unit. Furthermore, preferably, each corner connector unit in each frame unit is connected to a module unit of the same frame unit and to a module unit of an adjacent frame unit.Furthermore, preferably, in each frame unit, each module unit is connected to the corner connector unit of the same frame unit and to another module unit of the same frame unit, or to two module units of the same frame unit, or to one module unit of the same frame unit and to a corner connector unit of an adjacent frame unit. Preferably, each corner connector unit of the frame device is a corner connector unit according to the first aspect of the invention, and each module unit of the frame device is a module unit according to the second aspect of the invention.The features, technical effects and / or advantages described in connection with the corner connector unit according to the first aspect of the invention and the features, technical effects and / or advantages described in connection with the module unit according to the second aspect of the invention also apply, at least analogously, to the frame device according to the third aspect of the invention, so that a corresponding repetition is omitted here.

[0043] According to a fourth aspect of the invention, the aforementioned problem is solved by a protective system with the features of claim 10. The protective system comprises a frame device according to the third aspect of the invention and a protective device that is attached to the frame units of the frame device and extends between the frame units. Because the protective device is attached to the frame units of the frame device and extends between the frame units, a recess defined by the frame device can be concealed by means of the protective device. Preferably, the protective device is elastically deformable and can be brought into an elastically deformed state. Preferably, when attached to the frame units, the protective device is in the elastically deformed state such that the protective device extends along a plane under mechanical preload.Preferably, the protective device is an insect screen or incorporates an insect screen, or is a sunshade or incorporates a sunshade. Preferably, the protective system can also be designed and designated as an insect screen system, pollen screen system, fine dust screen system, or temperature screen system. The features, technical effects, and / or advantages described in connection with the corner connector unit according to the first aspect of the invention, the features, technical effects, and / or advantages described in connection with the module unit according to the second aspect of the invention, and the features, technical effects, and / or advantages described in connection with the frame device according to the third aspect of the invention also apply, at least analogously, to the protective system according to the fourth aspect of the invention, so that a corresponding repetition is omitted here.

Additionally, a guide groove 45 extends from the first plane to the second plane, at least partially between the first connecting section 27 of the module unit 3 and the mounting section 37 of the module unit 3, and at least partially between the second connecting section 29 of the module unit 3 and the mounting section 37 of the module unit 3.

[0053] The frame device 5 comprises several frame units. Each frame unit 47 of the multiple frame units comprises a corner connector unit 1 and a module unit 3. The corner connector unit 1 and the module unit 3 of each frame unit 47 are connected to each other. Furthermore, each frame unit 47 comprises additional module units, with each module unit 3 of the additional module units being constructed in the same way as module unit 3. Thus, module unit 3 and the additional module units are identical in construction. The identical construction of the module units ensures that they can be manufactured particularly efficiently, since the module units can be produced, for example, using the same tooling, such as an injection mold.The frame unit 47 thus comprises a multitude of module units, the multitude of which includes module unit 3 and the further module units. The characteristics, technical effects, and / or advantages described in connection with "the module unit" apply at least analogously to each module unit 3, i.e., also to the "further module unit" and the "further module units." Therefore, each module unit 3 is also designated with the same reference symbol in the figures.

[0054] Module unit 3 can also be referred to as the first module unit 3 of the plurality of module units of the corresponding frame unit 47. The first module unit 3 of the plurality of module units of the corresponding frame unit 47 is thus connected to the corner connector unit 1 of the corresponding frame unit 47. A second module unit 3 of the plurality of module units of the corresponding frame unit 47, which can also be referred to as the first module unit 3 of the further module units of the corresponding frame unit 47, is connected both to the first module unit of the plurality of module units of the corresponding frame unit 47 and to a third module unit of the plurality of module units of the corresponding frame unit 47, which can also be referred to as the second module unit 3 of the further module units of the corresponding frame unit 47.Thus, in each frame unit 47, the module units of the plurality of module units are connected to one another in such a way that, with the exception of the first module unit 3 of the plurality of module units and one last module unit of the plurality of module units, each module unit of the plurality of module units is connected to two corresponding adjacent module units of the plurality of module units in such a way that the module units of the plurality of module units are arranged one after the other in ascending order from the first module unit to the last module unit. The first module unit 3 of the plurality of module units is connected to the corner connector unit 1 of the corresponding frame unit 47 and to the second module unit of the plurality of module units. Furthermore, the last module unit of the plurality of module units is connected to a corner connector unit 1 of an adjacent frame unit 47 and to a penultimate module unit of the plurality of module units.Figures 17 and 18 each show a corner connector unit 1 of a corresponding frame unit 47. Figures 17 and 18 also each show a first module unit 3 of the corresponding frame unit 47 and a last module unit of an adjacent frame unit 47. Figure 19 shows sections of each frame unit 47, with the corner connector unit 1, the first module unit 3, and the last module unit being shown for each frame unit 47. Each first module unit 3 and each last module unit of each frame unit 47 is designated with the reference numeral 3, since, as already described, the module units are identically constructed. The corner connector unit 1 is thus designed for a frame unit 47 of the frame device 5. Likewise, the module unit 3 is designed for a frame unit 47 of the frame device 5.

[0055] The protective system 7 comprises the frame device 5 and a protective device that is attached to the frame units of the frame device 5 and extends between the frame units. Because the protective device is attached to the frame units of the frame device 5 and extends between them, it can cover a recess defined by the frame device 5. Preferably, the protective device is elastically deformable and can be brought into an elastically deformed state. Preferably, when attached to the frame units, the protective device is in the elastically deformed state such that it extends along a plane under mechanical preload. Preferably, the protective device is an insect screen or includes an insect screen, or is a sunshade or includes a sunshade.Preferably, the protection system 7 can also be designed and designated as an insect protection system, pollen protection system, fine dust protection system, or temperature protection system. Each corner connector unit 1 of each frame unit 47 of the multiple frame units is a corner connector unit 1, which will be discussed in more detail below. The corner connector units are identically constructed, which can also be described as identically designed. Because the corner connector units are identically constructed, it is ensured that they can be manufactured particularly efficiently, since they can be produced using the same tool, such as an injection mold. Likewise, each module unit 3 of the module units of each frame unit 47 of the multiple frame units is a module unit 3, which will be discussed in more detail below.As previously described, the module units have an identical structure, which can also be described as identical design. This identical structure ensures particularly efficient manufacturing, as the module units can be produced using the same tooling, such as an injection mold.

[0056] A significant advantage of the present invention is that each corner connector unit 1 can be connected to each module unit 3, and each module unit 3 can in turn be connected to any other module unit 3. When a particular corner connector unit 1 is connected to a particular module unit 3, this state can also be described as the connected state of that particular corner connector unit 1 and that particular module unit 3. Likewise, when a particular module unit 3 is connected to another particular module unit 3, this state can also be described as the connected state of that particular module unit 3 and that other particular module unit 3. Using such interconnected module units, frame units of varying lengths can be manufactured, and corner connector units compatible with the module units are also provided.so that for each length of a corresponding frame unit 47, a transition to an adjacent frame unit 47 is clearly defined by means of the corner connector unit 1 of the corresponding frame unit 47, and, for example, connecting sections on the module units that would ensure a connection of two module units can be dispensed with, such that a direction of extension 31 of a first module unit 3 of the two module units, along which the first module unit 3 extends from a first connecting section 27 to a second connecting section 29, and a direction of extension 31 of a second module unit of the two module units, along which the second module unit 3 extends from a first connecting section 27 to a second connecting section 29, run along two perpendicular straight lines. Thus, the module unit 3 can have a particularly large number of outer surfaces extending along the direction of extension 31.which extend continuously from the first level to the second level, thus ensuring safe handling for a user of the module unit 3. Furthermore, the corner connector unit 1 can be designed and adapted for use as a connecting piece between two corresponding frame units. For example, the dimensions of the corner connector unit 1 can be adapted to a dimension of the module unit 3 measured perpendicular to the extension direction 31 of the module unit 3, so that even at the transition from one frame unit 47 to the next frame unit 47, many outer surfaces extending continuously from the first level to the second level can be provided on the corner connector unit 1, thus ensuring safe handling for a user of the corner connector unit 1.

[0057] As previously described, corner connector unit 1 has the first connection section 9 and the second connection section 11. As also previously described, module unit 3 has the first connection section 27 and the second connection section 29. Corner connector unit 1 can be connected to the first connection section 9 and the second connection section 29 of a first module unit 3. Furthermore, corner connector unit 1 can be connected to the second connection section 11 and the first connection section 27 of a second module unit 3. Module unit 3, i.e., each module unit 3, and thus both the first and second module units 3, can be connected to the second connection section 29 of another identically constructed module unit 3 via the first connection section 27, or to the second connection section 11 of corner connector unit 1. Furthermore, module unit 3,Thus, each module unit 3, and therefore both the first module unit 3 and the second module unit 3, can be connected via the second connecting section 29 to a first connecting section 27 of an identically constructed further module unit 3, or to the first connecting section 9 of the corner connector unit 1. Furthermore, the first connecting section 9 of the corner connector unit 1 and the first connecting section 27 of each module unit 3 are identically constructed, and the second connecting section 11 of the corner connector unit 1 and the second connecting section 29 of each module unit 3 are also identically constructed. Because the corner connector unit 1 can be connected via the first connecting section 9 to the second connecting section 29 of the first module unit 3, and the corner connector unit 1 can be connected via the second connecting section 11 to the first connecting section 27 of the second module unit 3,The fact that the module unit 3 can be connected to a second connecting section 29 of an identically constructed further module unit 3 via the first connecting section 27, or to the second connecting section 11 of the corner connector unit 1, and that the module unit 3 can be connected to a first connecting section 27 of an identically constructed further module unit 3 via the second connecting section 29, or to the first connecting section 9 of the corner connector unit 1, ensures that each frame unit 47 of the frame device 5 can be constructed using corner connector units and identically constructed module units. Furthermore, the first connecting section 9 of the corner connector unit 1 and the second connecting section 11 of the corner connector unit 1 are designed such thatthat the first connecting section 9 of the corner connector unit 1 can be connected to the second connecting section 29 of the first module unit 3, and the second connecting section 11 of the corner connector unit 1 can be connected to the first connecting section 27 of the second module unit 3, such that the extension direction 31 of the first module unit 3, along which the first module unit 3 extends from the first connecting section 27 to the second connecting section 29, and an extension direction 31 of the second module unit 3, along which the second module unit 3 extends from the first connecting section 27 to the second connecting section 29, run along two transverse straight lines. This is achieved by the fact that the first connecting section 9 of the corner connector unit 1 and the second connecting section 11 of the corner connector unit 1 are designed in such a way thatthat the first connecting section 9 of the corner connector unit 1 can be connected to the second connecting section 29 of the first module unit 3 and the second connecting section 11 of the corner connector unit 1 can be connected to the first connecting section 27 of the second module unit 3 such that the extension direction 31 of the first module unit 3, along which the first module unit 3 extends from the first connecting section 27 to the second connecting section 29, and an extension direction 31 of the second module unit 3, along which the second module unit 3 extends from the first connecting section 27 to the second connecting section 29, run along two transverse straight lines, it is ensured that the corner connector unit 1 connects two module units, namely the first module unit 3 and the second module unit 3, from two different frame units,namely, the first module unit 3 of a first frame unit 47 and the second module unit 3 of a second frame unit 47 can be connected to each other, wherein the two module units extend along two straight lines perpendicular to each other, along which one of the two frame units also extends. Thus, the first frame unit 47, which has the first module unit 3, can extend along a first straight line along which the extension direction 31 of the first module unit 3 runs, and the second frame unit 47, which has the second module unit 3, can extend along a second straight line along which the extension direction 31 of the second module unit 3 runs, wherein the first straight line and the second straight line are perpendicular to each other.

[0058] In the embodiment of the corner connector unit 1 shown schematically in Figures 1 to 8, the extension direction 31 of the first module unit 3 and the extension direction 31 of the second module unit 3 run along two transverse straight lines such that the lines are perpendicular to each other. The first connecting section 9 and the second connecting section 11 of the corner connector unit 1 are designed such that the first connecting section 9 of the corner connector unit 1 can be connected to the second connecting section 29 of the first module unit 3, and the second connecting section 11 of the corner connector unit 1 can be connected to the first connecting section 27 of the second module unit 3, such that the extension direction 31 of the first module unit 3, along which the first module unit 3 extends from the first connecting section 27 to the second connecting section 29,and the extension direction 31 of the second module unit 3, along which the second module unit 3 extends from the first connection section 27 to the second connection section 29, runs along two perpendicular straight lines. This is achieved by the fact that the first connection section 9 of the corner connector unit 1 and the second connection section 11 of the corner connector unit 1 are designed such that the first connection section 9 of the corner connector unit 1 can be connected to the second connection section 29 of the first module unit 3, and the second connection section 11 of the corner connector unit 1 can be connected to the first connection section 27 of the second module unit 3, such that the extension direction 31 of the first module unit 3, along which the first module unit 3 extends from the first connection section 27 to the second connection section 29, and the extension direction 31 of the second module unit 3,By ensuring that the corner connector unit 1 can connect two module units, namely the first module unit 3 and the second module unit 3, from two different frame units, namely the first module unit 3 from the first frame unit 47 and the second module unit 3 from the second frame unit 47, with the two module units extending along two perpendicular lines, along which one of the two frame units also extends. Thus, the first frame unit 47, which includes the first module unit 3, can extend along a first line along which the extension direction 31 of the first module unit 3 runs, and the second frame unit 47,which has the second module unit 3, extend along a second straight line, along which the extension direction 31 of the second module unit 3 runs, wherein the first straight line and the second straight line are perpendicular to each other.

[0059] Furthermore, the first connecting section 27 of the module unit 3 and the second connecting section 29 of the module unit 3 are designed such that both the first connecting section 27 of the module unit 3 can be connected to the second connecting section 29 of an identically constructed further module unit 3 in such a way that the extension direction 31 of the module unit 3 and the extension direction 31 of the further module unit 3 run along the same straight line, and the second connecting section 29 of the module unit 3 can be connected to the first connecting section 27 of an identically constructed further module unit 3 in such a way that the extension direction 31 of the module unit 3 and the extension direction 31 of the further module unit 3 run along the same straight line. Because the first connecting section 27 of the module unit 3 and the second connecting section 29 of the module unit 3 are designed in such a way,that both the first connecting section 27 of the module unit 3 can be connected to the second connecting section 29 of an identically constructed further module unit 3 in such a way that the extension direction 31 of the module unit 3 and the extension direction 31 of the further module unit 3 run along the same straight line, and that the second connecting section 29 of the module unit 3 can be connected to the first connecting section 27 of an identically constructed further module unit 3 in such a way that the extension direction 31 of the module unit 3 and the extension direction 31 of the further module unit 3 run along the same straight line, it is ensured that each frame unit 47 of the frame device 5, which is constructed at least partially using identically constructed module units,along a direction of extension of the frame unit 47, at least sectionally, it can be formed by the identically constructed and interconnected module units, wherein the direction of extension of the frame unit 47 runs along the same straight line along which the directions of extension of the module units also run.

[0060] As previously described, the corner connector unit 1 has the first connecting section 9 and the second connecting section 11. The first connecting section 9 has the first contact surface 13, which extends along the first level, and the second connecting section 11 has the second contact surface 15, which extends along the second level. Here, the first level and the second level refer to the corner connector unit 1.Because the first mounting surface 13 extends along the first level, the first mounting surface 13 provides an optimal mounting surface for the second mounting surface 35 of the module unit 3, which extends along the second level relating to the module unit 3, so that in a connected state of the corner connector unit 1 and the module unit 3 a particularly robust connection is established between the corner connector unit 1 and the module unit 3, especially against tilting of the module unit 3 relative to the corner connector unit 1 in the sense of pivoting the first connection section 27 perpendicular to the extension direction 31 about the second connection section 29.Because the second mounting surface 15 extends along the second plane, it provides an optimal mounting surface for the first mounting surface 33 of the module unit 3, which extends along the first plane relating to the module unit 3. This results in a particularly robust connection between the corner connector unit 1 and the module unit 3 when connected, especially against tilting of the module unit 3 relative to the corner connector unit 1 by means of a pivoting of the second connection section 29 perpendicular to the direction of extension 31 about the first connection section 27. The first plane relating to the corner connector unit 1 and the second plane relating to the corner connector unit 1 intersect.The fact that the first plane relating to the corner connector unit 1 and the second plane relating to the corner connector unit 1 intersect ensures that the first plane points in a first direction and the second plane points in a second direction, with the first direction and the second direction running along two perpendicular straight lines. In the embodiment of the corner connector unit 1 shown schematically in Figures 1 to 8, the first plane relating to the corner connector unit 1 and the second plane relating to the corner connector unit 1 intersect at a right angle.The fact that the first plane relating to the corner connector unit 1 and the second plane relating to the corner connector unit 1 intersect at a right angle ensures that the corner connector unit 1 can connect two module units of two frame units, wherein the two module units extend along two perpendicular lines and the two frame units extend along the same two perpendicular lines.

[0061] As already described, the corner connector unit 1 has the fastening section 17, which extends from the first level relating to the corner connector unit 1 to the second level relating to the corner connector unit 1 and to which a section of the protective device, which can also be referred to as the first section of the protective device, can be attached.Because the corner connector unit 1 has a fastening section 17 extending from the first level to the second level of the corner connector unit 1, it is ensured that the fastening section 17 extends along the entire length of the corner connector unit 1 between two sections of the corner connector unit 1, each of which can be fitted with a module unit 3. This allows for continuous fastening of the protective device within each frame unit 47 and each frame device 5. The continuous fastening of the protective device to the corner connector unit 1 ensures a particularly robust mechanical design of the protective system 7.As previously described, the fastening section 17 has the contact surface 19 and several projections extending away from the contact surface 19, each projection 21 extending away from the contact surface 19. Because the fastening section 17 has the contact surface 19 and several projections extending away from the contact surface 19, each projection 21 extending away from the contact surface 19, it is ensured that the section of the protective device is secured against slippage relative to the corner connector unit 1 and is generally secured against slippage parallel to the contact surface 19. Each projection 21 has a cross-section perpendicular to the direction of extension, viewed along its extension from the contact surface 19 to a free end of the projection 21, and this cross-section is constant along the direction of extension.Because each projection 21 has a cross-section perpendicular to its direction of extension, measured from the mounting surface 19 to a free end of the projection 21, and this cross-section is constant along the direction of extension, it is ensured that the section of the protective device can be connected to and detached from the corner connector unit 1 particularly easily. The projections are arranged sequentially along the corner connector unit 1, from the first level to the second level, so that the section of the protective device can be connected to the corner connector unit 1 at several points along the corner connector unit 1 using the projections.In the embodiment of the corner connector unit 1 shown schematically in Figures 1 to 8, two groups of protrusions are provided, wherein the protrusions of a first group 49 of the second group are arranged one after the other from the first plane along a first straight line and the protrusions of a second group 51 of the second group are arranged one after the other from the second plane along a second straight line, wherein the first straight line and the second straight line run perpendicular to each other.By providing two groups of projections, wherein the projections of a first group 49 and the second group are arranged one behind the other along a first straight line from the first plane, and the projections of a second group 51 are arranged one behind the other along a second straight line from the second plane, with the first and second straight lines running perpendicular to each other, it is ensured that the section of the protective device can be attached to the corner connector unit 1 in a particularly optimal way, since, for example, a section of the protective device can lie flat on a section of the corner connector unit 1 and can be held in this flat-lying configuration by means of the first group 49 and the second group 51. In the embodiment of the corner connector unit 1 shown schematically in Figures 1 to 8, the first straight line and the second straight line run perpendicular to each other.The fact that the first and second lines are perpendicular to each other ensures that, when the corner connector unit 1 connects two module units whose extension directions run along perpendicular lines, the protective device can be optimally attached to the corner connector unit 1. Furthermore, in the embodiment of the corner connector unit 1 shown schematically in Figures 1 to 8, a section of the contact surface 19 of the fastening section 17 is provided between the first group 49 and the second group 51, on which no protrusion 21 is provided; this section of the contact surface 19 can also be referred to as the protrusion-free section of the contact surface 19.By providing a section of the contact surface 19 of the fastening section 17 between the first group 49 and the second group 51, on which no protrusion 21 is provided, it is ensured that the protective device can only be attached to the fastening section 17 in such a way that the forces acting on the protective device from the fastening section 17 in the attached state are optimally aligned. In the embodiment of the corner connector unit 1 shown schematically in Figures 1 to 8, these forces preferably act only parallel or perpendicular to each other, so that the protective device can be optimally pre-tensioned by means of the protrusions.

[0062] As previously described, the corner connector unit 1 has a third contact surface 23 that extends along the third plane, intersecting both the first and second planes. As also previously described, the third contact surface 23 is designed such that when the first section of the protective device is attached to the mounting section 17, a second section of the protective device can rest against the third contact surface 23.Because the corner connector unit 1 has the third contact surface 23, which extends along the third plane that intersects both the first plane and the second plane, and the third contact surface 23 is designed such that when the first section of the guard is attached to the mounting section 17, a second section of the guard can abut the third contact surface 23, a spatial separation is ensured between the attachment of the first section of the guard to the mounting section 17 and the attachment of the second section of the guard to the third contact surface 23, so that in the attached state of the guard to the mounting section 17 the third contact surface 23 can ensure an optimal shape of the guard.In the embodiment of the corner connector unit 1 shown schematically in Figures 1 to 8, the third plane intersects both the first and second planes at a right angle. This right-angle intersecting of both planes ensures that the third contact surface 23 provides a contact surface for the protective device that extends parallel to each direction 31 of each module unit 3 connected to the corner connector unit 1.

[0063] Furthermore, in the embodiment of the corner connector unit 1 shown schematically in Figures 1 to 8, the third contact surface 23 points in a first direction, and each projection 21 extends from the contact surface 19 in a second direction opposite to the first direction. Because the third contact surface 23 points in the first direction and each projection 21 extends from the contact surface 19 in a second direction opposite to the first direction, it is ensured that a section of the protective device, which can also be referred to as the second section, can abut the third contact surface 23 and be held in this position with particular mechanical robustness by the projections engaging the protective device in the second direction.

[0064] As previously described, the guide groove 25 extends from the first level to the second level, at least partially between the first connecting section 9 of the corner connector unit 1 and the fastening section 17 of the corner connector unit 1, and at least partially between the second connecting section 11 of the corner connector unit 1 and the fastening section 17 of the corner connector unit 1. The guide groove 25 allows a cutting tool to be guided particularly reliably along the corner connector unit 1, enabling it to cut off a protruding area of ​​a guard blank along the edges of the corner connector unit 1, thus ensuring an optimally shaped edge area of ​​the guard manufactured from the guard blank. This is achieved by the fact that the guide groove 25 extends from the first level to the second level, at least partially between the first connecting section 9 of the

[0065] Corner connector unit 1 and the fastening section 17 of the corner connector unit 1 and at least sectionally between the second connecting section 11 of the

[0066] The guide groove 25 extends along the entire length of the corner connector unit 1 between two sections of the corner connector unit 1, to each of which a module unit 3 can be attached, thus enabling continuous separation of the protruding area of ​​the protective device blank within each frame unit 47 and each frame device 5.The continuous removal of the protruding area of ​​the protective device blank at the corner connector unit 1 ensures particularly user-friendly use of the protective system 7, since, for example, the corner connector units and module units can first be connected to each other, then the protective device can be attached to the corner connector units and module units, and subsequently the protruding area of ​​the protective device blank can be removed, thus eliminating the need to measure the actual dimensions of the protective device.The fact that the guide groove 25 extends at least partially between the first connecting section 9 of the corner connector unit 1 and the fastening section 17 of the corner connector unit 1, and at least partially between the second connecting section 11 of the corner connector unit 1 and the fastening section 17 of the corner connector unit 1, ensures that connecting the corner connector unit 1 to two module units can be carried out spatially separately from attaching the protective device to the corner connector unit 1. This spatial separation ensures that the first connecting section 9, the second connecting section 11, and the fastening section 17 can be individually adapted for their intended function.

[0067] Furthermore, the contact surface 19 of the fastening section 17 is designed such that the distance, measured perpendicular to the third plane, between the third contact surface 23 and the contact surface 19 of the fastening section 17 increases from the guide groove 25 towards the vicinity of the corner connector unit 1. This design of the contact surface 19 of the fastening section 17, such that the distance, measured perpendicular to the third plane, between the third contact surface 23 and the contact surface 19 of the fastening section 17 increases from the guide groove 25 towards the vicinity of the corner connector unit 1, ensures that when a section of the protective device is connected to the fastening section 17 and rests against the contact surface 19, it engages the protrusions in a particularly robust mechanical manner.

[0068] As previously described, module unit 3 extends from the first connection section 27 along the extension direction 31 to the second connection section 29. As also previously described, the first connection section 27 of module unit 3 has the first mounting surface 33, which extends along the first level, and the second connection section 29 of module unit 3 has the second mounting surface 35, which extends along the second level. Here, the first level and the second level refer to module unit 3.Because the first mounting surface 33 extends along the first level, the first mounting surface 33 provides an optimal mounting surface for the second mounting surface 15 of the corner connector unit 1, which extends along the second level relating to the corner connector unit 1, so that in a connected state of the corner connector unit 1 and the module unit 3 a particularly robust connection is established between the corner connector unit 1 and the module unit 3, especially against tilting of the module unit 3 relative to the corner connector unit 1 in the sense of pivoting the second connection section 29 perpendicular to the extension direction 31 about the first connection section 27.Because the second mounting surface 35 extends along the second plane, it provides an optimal mounting surface for the first mounting surface 13 of the corner connector unit 1, which extends along the first plane relating to the corner connector unit 1. This results in a particularly robust connection between the corner connector unit 1 and the module unit 3 when connected, especially against tilting of the module unit 3 relative to the corner connector unit 1 by means of a pivoting of the first connection section 27 perpendicular to the direction of extension 31 about the second connection section 29. The first plane relating to the module unit 3 and the second plane relating to the module unit 3 extend parallel to each other.Because the first plane and the second plane relating to the module unit 3 extend parallel to each other, it is ensured that the first plane points in a first direction and the second plane points in a second direction, with the first direction and the second direction running along the same straight line. In the embodiment of the module unit 3 shown schematically in Figures 9 to 16, both the first plane and the second plane extend perpendicular to the direction of extension 31.Because both the first and the second plane run perpendicular to the extension direction 31, a connection between the module unit 3 and two further module units or between the module unit 3 and another module unit 3 and a corner connector unit 1 can each be designed to form a frame unit 47 which also extends along the extension direction 31 in a particularly robust mechanical manner.

[0069] As previously described, the module unit 3 has a mounting section 37 that extends from the first level to the second level of the module unit 3 and to which a section of the protective device, which can also be referred to as the first section of the protective device, can be attached. Because the module unit 3 has the mounting section 37 extending from the first level to the second level of the module unit 3, it is ensured that the mounting section 37 extends along the entire module unit 3 between two sections of the module unit 3, to each of which a corner connector unit 1 or a module unit 3 can be attached, thus enabling continuous mounting of the protective device within each frame unit 47 and each frame device 5.The continuous attachment of the protective device to the module unit 3 ensures a particularly robust mechanical design of the protective system 7. In the embodiment of the module unit 3 shown schematically in Figures 9 to 16, the fastening section 37 extends from the first plane relating to the module unit 3 along the direction of extension 31 to the second plane relating to the module unit 3, thus ensuring that the protective device is attached to the module unit 3 along the direction of extension 31.

[0070] As previously described, the fastening section 37 has the mounting surface 39 and the several projections extending away from the mounting surface 39, each projection 41 of the several projections extending away from the mounting surface 39. Because the fastening section 37 has the mounting surface 39 and the several projections extending away from the mounting surface 39, each projection 41 of the several projections extending away from the mounting surface 39, it is ensured that the section of the protective device is secured against slippage relative to the module unit 3 and is generally secured against slippage parallel to the mounting surface 39. Each projection 41 has a cross-section arranged perpendicular to the direction of extension, viewed along its extension from the mounting surface 39 to a free end of the projection 41, and this cross-section is constant along the direction of extension.Because each projection 41 has a cross-section perpendicular to its extension direction, measured from the mounting surface 39 to a free end of the projection 41, and this cross-section is constant along the extension direction, it is ensured that the section of the protective device can be connected to and detached from the module unit 3 particularly easily. The projections are arranged one after the other along the module unit 3, from the first level to the second level, so that the section of the protective device can be connected to the module unit 3 at several points along the module unit 3 using the projections. In the embodiment of the module unit 3 shown schematically in Figures 9 to 16, a group of projections is provided, with the projections of the group arranged one after the other along the extension direction 31.By providing a group of protrusions, wherein the protrusions of the group are arranged one after the other along the extension direction 31, it is ensured that the section of the protective device can be continuously attached to the module unit 3 along the extension direction 31, since, for example, a section of the protective device can lie flat on a section of the corner connector unit 1 and can be held in this flat-lying configuration by means of the group.

[0071] As previously described, module unit 3 has a third mounting surface 43 that extends along the third level, intersecting both the first and second levels. As also previously described, the third mounting surface 43 is designed such that when the first section of the protective device is attached to the mounting section 37, a second section of the protective device can rest against the third mounting surface 43.Because the module unit 3 has the third mounting surface 43, which extends along the third plane that intersects both the first plane and the second plane, and the third mounting surface 43 is designed such that when the first section of the protective device is attached to the mounting section 37, a second section of the protective device can abut the third mounting surface 43, a spatial separation is ensured between the attachment of the first section of the protective device to the mounting section 37 and the attachment of the second section of the protective device to the third mounting surface 43, so that in the attached state of the protective device to the mounting section 37 the third mounting surface 43 can ensure an optimal shape of the protective device.In the embodiment of the module unit 3 shown schematically in Figures 9 to 16, the third plane intersects both the first and second planes at a right angle. This right-angle intersecting of both planes ensures that the third contact surface 43 provides a contact surface for the protective device that extends parallel to the direction of extension 31 of the module unit 3.

[0072] Furthermore, in the embodiment of the module unit 3 shown schematically in Figures 9 to 16, the third contact surface 43 points in a first direction, and each projection 41 extends from the contact surface 39 in a second direction opposite to the first direction. Because the third contact surface 43 points in the first direction and each projection 41 extends from the contact surface 39 in a second direction opposite to the first direction, it is ensured that a section of the protective device, which can also be referred to as the second section, can abut the third contact surface 43 and be held in this position with particular mechanical robustness by the projections engaging the protective device in the second direction.

[0073] As previously described, the guide groove 45 extends from the first level to the second level, at least partially between the first connecting section 27 of the module unit 3 and the fastening section 37 of the module unit 3, and at least partially between the second connecting section 29 of the module unit 3 and the fastening section 37 of the module unit 3. The guide groove 45 enables a cutting tool to be guided particularly reliably along the module unit 3, allowing the cutting tool to be guided along the edges of the module unit 3 in order to cut off a protruding area of ​​a guard blank, thus ensuring an optimally shaped edge area of ​​the guard manufactured from the guard blank.By extending from the first level to the second level, at least partially between the first connecting section 27 of the module unit 3 and the fastening section 37 of the module unit 3, and at least partially between the second connecting section 29 of the module unit 3 and the fastening section 37 of the module unit 3, it is ensured that the guide groove 45 extends along the entire module unit 3 between two sections of the module unit 3, to which a corner connector unit 1 or a module unit 3 can be attached, so that continuous separation of the protruding area of ​​the protective device blank is made possible within each frame unit 47 and each frame device 5.The continuous removal of the protruding area of ​​the protective device blank at the module unit 3 ensures particularly user-friendly use of the protective system 7, since, for example, the corner connector units and module units can first be connected to each other, then the protective device can be attached to the corner connector units and module units, and subsequently the protruding area of ​​the protective device blank can be removed, thus eliminating the need to measure the actual required dimensions of the protective device.The fact that the guide groove 45 extends at least partially between the first connecting section 27 of the module unit 3 and the fastening section 37 of the module unit 3, and at least partially between the second connecting section 29 of the module unit 3 and the fastening section 37 of the module unit 3, ensures that connecting the module unit 3 to a corner connector unit 1 and to another module unit 3, or to two module units, can be carried out spatially separately from attaching the protective device to the module unit 3. This spatial separation ensures that the first connecting section 27, the second connecting section 29, and the fastening section 37 can be individually adapted for their intended function.

[0074] Furthermore, the contact surface 39 of the mounting section 37 is designed such that the distance, measured perpendicular to the third plane, between the third contact surface 43 and the contact surface 39 of the mounting section 37 increases from the guide groove 45 towards the surroundings of the module unit 3. This design of the contact surface 39 of the mounting section 37, such that the distance, measured perpendicular to the third plane, between the third contact surface 43 and the contact surface 39 of the mounting section 37 increases from the guide groove 45 towards the surroundings of the module unit 3, ensures that when a section of the protective device is connected to the mounting section 37 and rests against the contact surface 39, it engages the protrusions in a particularly robust mechanical manner.

[0075] In the connected state of the frame device 5, each corner connector unit 1 is connected to two module units, and each module unit 3 is connected either to one corner connector unit 1 and one module unit 3, or to two module units. In the connected state of the frame device 5, the first level relating to each corner connector unit 1 corresponds to the second level relating to one of the module units 3 connected to the corner connector unit 1. Furthermore, in the connected state of the frame device 5, the second level relating to each corner connector unit 1 corresponds to the first level relating to another of the module units 3 connected to the corner connector unit 1.When the frame device 5 is connected, the first level relating to each module unit 3 connected to two module units corresponds to the second level relating to one of the module units 3 connected to that module unit 3. Furthermore, when the frame device 5 is connected, the second level relating to each module unit 3 connected to two module units corresponds to the first level relating to another of the module units 3 connected to that module unit 3. Additionally, when the frame device 5 is connected, the fastening sections of the corner connector units and the fastening sections of the module units form a continuous and circumferential fastening section of the frame device 5, allowing the protective device to be continuously and circumferentially attached to the frame device 5.Furthermore, in the connected state of the frame device 5, the guide grooves of the corner connector units and the guide grooves of the module units form a continuous and circumferential guide groove of the frame device 5, so that a cutting tool can be guided particularly reliably along the frame device 5 with the help of the continuous and circumferential guide groove in order to guide the cutting tool along the edges of the frame device 5 in order to cut off a protruding area of ​​a guard device blank, so that an optimally shaped edge area of ​​the guard device produced from the guard device blank is ensured.

[0076] Furthermore, in the embodiment of the corner connector unit 1 according to the invention shown in Figures 1 to 8, the first connecting section 9 of the corner connector unit 1 has a plug-in projection 53 and the second connecting section 11 of the corner connector unit 1 has a plug-in recess 55. Because the first connecting section 9 of the corner connector unit 1 has the plug-in projection 53 and the second connecting section 11 of the corner connector unit 1 has the plug-in recess 55, particularly simple connecting elements are provided for connecting the corner connector unit 1 to one or more module units. The plug-in projection 53 and the plug-in recess 55 are dovetail-shaped.Because the plug-in projection 53 and the plug-in recess 55 are dovetail-shaped, a mechanically robust connection between the corner connector unit 1 and the module unit 3 and further module units is ensured without the need for additional connecting means, making the connection of the corner connector unit 1 with the module units particularly user-friendly.

[0077] Furthermore, in the embodiment of the corner connector unit 1 according to the invention shown in Figures 1 to 8, two dovetail legs extend away from the first contact surface 13 in such a way that a distance parallel to the first contact surface 13 between a first dovetail leg 61 of the two dovetail legs and a second dovetail leg 63 of the two dovetail legs increases with increasing distance from the first contact surface 13.Because the distance between the first dovetail leg 61 and the second dovetail leg 63, which runs parallel to the first contact surface 13, increases with increasing distance from the first contact surface 13, the first dovetail leg 61 and the second dovetail leg 63 define a cavity 65 between them, into which the first dovetail leg 61 and the second dovetail leg 63 are inserted by elastic deformation of the first dovetail leg 61 and the second.

[0078] dovetail leg 63 can be deformed into it, so that in the connected state the first dovetail leg 61 and the second

[0079] The dovetail legs 63 can be elastically deformed, so that in the connected state a particularly backlash-free force connection can be ensured by a force-locking contact of the first dovetail leg 61 of the corner connector unit 1 on a first dovetail contact surface 67 of the second connection section 29 of the module unit 3 and of the second dovetail leg 63 of the corner connector unit 1 on a second dovetail contact surface 69 of the second connection section 29 of the module unit 3 between the corner connector unit 1 and each module unit 3 (see Figure 12).

[0080] A reinforcing section 71 extends between the first dovetail leg 61 and the second dovetail leg 63. The reinforcing section 71 is connected to the first dovetail leg 61 and to the second dovetail leg 63 in such a way that when the first dovetail leg 61 and the second dovetail leg 63 are deformed into the cavity 65 by elastic deformation of the first dovetail leg 61 and the second dovetail leg 63, a compressive force acts on the reinforcing section 71 from the first dovetail leg 61 and from the second dovetail leg 63.The reinforcement section 71 thus reduces deformation of the first dovetail leg 61 and the second dovetail leg 63 into the cavity 65 when the first dovetail leg 61 and the second dovetail leg 63 are subjected to a load in the direction of the cavity 65, so that in the connected state the force transmission between the first dovetail leg 61 of the corner connector unit 1 and the first dovetail contact surface 67 of the second connection section 29 of the module unit 3 and between the second dovetail leg 63 of the corner connector unit 1 and the second dovetail contact surface 69 of the second connection section 29 of the module unit 3 is mechanically particularly robust.

[0081] Furthermore, in the embodiment of the module unit 3 according to the invention shown in Figures 9 to 16, the first connecting section 27 of the module unit 3 has a plug-in projection 57 and the second connecting section 29 of the module unit 3 has a plug-in recess 59. Because the first connecting section 27 of the module unit 3 has the plug-in projection 57 and the second connecting section 29 of the module unit 3 has the plug-in recess 59, particularly simple connecting means are provided for connecting the module unit 3 with identically constructed further module units and with the corner connector unit 1. The plug-in projection 57 and the plug-in recess 59 are dovetail-shaped.Because the plug-in projection 57 and the plug-in recess 59 are dovetail-shaped, a mechanically robust connection between the module unit 3 and other module units, as well as between the module unit 3 and the corner connector unit 1, is ensured without the need for additional connecting means, making the connection of the module unit 3 to the other module units and to the corner connector unit 1 particularly user-friendly.

[0082] Furthermore, in the embodiment of the module unit 3 according to the invention shown in Figures 9 to 16, two dovetail legs extend away from the first contact surface 33 such that the distance between a first dovetail leg 73 of the two dovetail legs and a second dovetail leg 75 of the two dovetail legs, running parallel to the first contact surface 33, increases with increasing distance from the first contact surface 33. Because the distance between the first dovetail leg 73 and the second dovetail leg 75, running parallel to the first contact surface 33, increases with increasing distance from the first contact surface 33, the first dovetail leg 73 and the second dovetail leg 75 define a cavity 77 between them.into which the first dovetail leg 73 and the second dovetail leg 75 can be deformed by elastic deformation of the first dovetail leg 73 and the second dovetail leg 75, so that in the connected state the first dovetail leg 73 and the second dovetail leg 75 can be elastically deformed, so that in the connected state a particularly backlash-free force connection is achieved by a force-fit contact of the first dovetail leg 73 of the module unit 3 with a first dovetail contact surface 67 of the second connecting section 29 of another module unit 3 or with a first dovetail contact surface 79 of the second connecting section 11 of the corner connector unit 1 and the second,

[0083] dovetail leg 75 of the module unit 3 on a second

[0084] The dovetail mounting surface 69 of the second connecting section 29 of the further module unit 3 or on a second dovetail mounting surface 81 of the second connecting section 11 of the corner connector unit 1 can be ensured either between the module unit 3 and a further module unit 3 or between the module unit 3 and the corner connector unit 1 (see Figures 4 and 12).

[0085] A reinforcing section 83 extends between the first dovetail leg 73 and the second dovetail leg 75. The reinforcing section 83 is connected to the first dovetail leg 73 and to the second dovetail leg 75 in such a way that when the first dovetail leg 73 and the second dovetail leg 75 are deformed into the cavity 77 by elastic deformation of the first dovetail leg 73 and the second dovetail leg 75, a compressive force acts on the reinforcing section 83 from the first dovetail leg 73 and from the second dovetail leg 75.The reinforcing section 83 thus reduces deformation of the first dovetail leg 73 and the second dovetail leg 75 into the cavity 77 when the first dovetail leg 73 and the second dovetail leg 75 are subjected to a load in the direction of the cavity 77, so that in the connected state the force transmission between the first dovetail leg 73 of the module unit 3 and the first dovetail contact surface 67 of the second connecting section 29 of another module unit 3 or the first dovetail contact surface 79 of the second connecting section 11 of the corner connector unit 1 and between the second dovetail leg 75 of the module unit 3 and the second dovetail contact surface 69 of the second connecting section 29 of the other module unit 3 or the second dovetail contact surface 81 of the second connecting section 11 of the corner connector unit 1 is mechanically particularly robust.It should be further noted that "having" does not exclude any other elements or steps, and "a" or "an" does not exclude a plurality. It should also be noted that features described with reference to one of the above embodiments may also be used in combination with other features of other embodiments described above.
