Description

The present invention relates to a holder for fastening a surface element of a sun, insect, rodent, dust and / or pollen protection device to a window frame or a door. The holder has a connecting region for connection to the surface element. In addition, the holder forms a fastening space into which a portion of the frame is to be inserted. The present invention furthermore relates to a sun, insect, rodent, dust and / or pollen protection device comprising a planar element for covering an opening of a window or a door and at least one holder for fastening the planar element to a window frame of the window or the door.Such a sun, insect, rodent, dust and / or pollen protection device is regularly attached to a window or a door for protecting the interior space, in particular the interior space of the building, delimited by the window or the door. As a rule, the surface element of the sun, insects, rodent, dust and / or pollen protection device, which extends in a planar manner, comprises a covering material, which is in particular configured as a grid, grid fabric, knitted fabric and / or knitted fabric, and a surface element frame which holds and surrounds the covering material. The surface element frame can be designed as a tenter frame.For fastening the surface element to the frame, holders of the type mentioned at the beginning can be used. In practice, such a holder is frequently formed in one piece and is manufactured, for example, from flat steel. The support may have a Z-shape in cross section, the Z-shape being understood to mean a three-armed arrangement in which each of the three legs is arranged at right angles to the respective adjacent leg and in which two outer ones of the legs extend in opposite directions and at opposite ends from a middle one of the legs. One of the outer legs forms the connecting region for in particular a firm connection to the surface element. The connecting region can have, for example, recesses for screw connection to the surface element. The two other legs, in particular together with the surface element, delimit the fastening space into which a section of the frame is to be inserted.Holders of the above-described type are, however, suitable only for certain frame thicknesses, which is why these holders can be used comparatively inflexible. A connection of such a holder to the frame is also frequently unstable and entails undesired movements of the surface element and associated noises. Furthermore, sun, insect, rodent, dust and / or pollen protection devices with such holders are relatively complicated to mount. Due to the often fixed connection of the holder and the surface element, such holders are usually associated with damage to the surface element, in particular to the surface element frame, for example due to penetration of screws. In addition, in the case of holders to be screwed to the surface element, these holders are exclusively suitable for use with surface elements which make such a screw connection possible at all. The range of application of the holders and the flexibility of the sun, insect, rodent, dust and / or pollen protection device are thus limited.The object of the present invention is therefore to provide a holder in which the disadvantages of the prior art are at least partially reduced. It is a further object of the present invention to provide a sun, insect, rodent, dust and / or pollen protection device in which the disadvantages of the prior art are at least partially reduced.The object is achieved by a holder according to claim 1 and a sun, insect, rodent, dust and / or pollen protection device according to claim 19. Advantageous further developments of the invention can be taken from the respective dependent claims referred back thereto, the following description and the figures.According to the invention, the holder has a two-part construction with a separate first holder part and a separate second holder part which, in the mounted position of the holder, engages with the first holder part. The first mounting part and the second mounting part are designed to be adjustable in an adjustment direction in order to adapt the fastening space to different frame thicknesses.With the holder according to the invention, the surface element is preferably to be arranged on the outside of the window frame, that is to say on a side of the window frame facing away from an interior space bounded by the window or the door. For this purpose, the connecting region, in particular the part of the holder forming the receiving space, is preferably formed in such a way that, in the mounted position of the holder, it is arranged on the outside of the frame.The window frame is understood to mean the frame of the window or of the door that is to be fixedly mounted. The window frame preferably has a web projecting toward the center of the window frame, which web partially covers a leaf of the window or of the door when viewed from an outer side of the window or of the door. In particular, the web of the frame is to be inserted into the fastening space. The frame thickness preferably relates to an extension of the web of the frame in the adjustment direction. The fastening space is understood to mean a space which is bounded at least on two sides but is not closed.The adjustment direction is in particular a double direction, along which the first mounting part and the second mounting part can be adjusted both towards one another and away from one another for adapting the fastening space. The adjustment direction runs in particular perpendicular to a plane spanned by the surface element.The adaptation of the fastening space is understood to mean a change in the extent of the fastening space in the adjustment direction, that is to say in particular along a direction running perpendicular to the planar element plane in the mounted position of the holder.The holding parts are preferably designed to be adjustable relative to one another in such a way that they can be connected to one another in different positions relative to one another. Preferably, the boundaries of the fastening space lying in the adjustment direction can be changed by adjusting the holding parts, in particular can be displaced towards one another and / or away from one another in the adjustment direction.Preferably, the holder has an extension of 10 millimeters to 70 millimeters, preferably of 20 millimeters to 60 millimeters, particularly preferably of 30 millimeters to 50 millimeters, in particular of 40 millimeters, in a direction transverse to the adjustment direction and in particular parallel to a longitudinal extension of the frame profile. The holder is thus particularly stable.The holder according to the invention is thus suitable for fastening to frame members of different frame thicknesses and is therefore of flexible design. The holder can also be mounted in a simple manner. The holder also makes a detachable, damage-free and / or residue-free connection to the window frame possible.In a preferred embodiment of the invention, the connecting region forms a receiving space into which a section of the planar element is to be inserted, in particular wherein the receiving space is a receiving groove bounded by the first mounting part, in particular on three sides. The receiving space is understood to mean a space bounded at least on two sides. The part of the holder forming the receiving space preferably forms a clip for in particular clamping connection to the holder part. The holder can thus be connected to the surface element in a simple manner in a detachable manner and without damage.In a further preferred embodiment, the first holding part forms a receiving stop delimiting the receiving space, up to which the planar element is to be inserted in its insertion direction through a receiving opening of the receiving space opposite the receiving stop. The receiving stop is formed in particular by a base of the first holding part. By means of the receiving stop, in the mounted position of the holder, a defined position of the surface element relative to the holder is achieved.Preferably, the first holding part has an additional stiffening base, which is arranged in particular parallel to the receiving stop and stiffens the receiving stop. For this purpose, the stiffening base is preferably connected to the receiving stop, in particular via connecting webs. The stiffening base is preferably arranged spaced apart from a base of the first holding part forming the receiving stop. The reinforcing floor additionally reinforces the floor forming the receiving region. When the holder is heated, for example by solar radiation, an undesired deformation of the holder, in particular a deformation of the receiving space, is at least reduced. Thus, the part of the holder forming the receiving space is formed more stably. The accommodation of the surface element is comparatively stable and secure.In a further preferred embodiment, the first holding part has a narrow point of the receiving space for fixing the surface element in the mounted position. Preferably, the constriction narrows the receiving space at least in regions, in particular in the adjustment direction. A section of the surface element, in particular the preferably present surface element frame, is thus fixed in a region of the receiving space bounded by the constriction after passing the constriction, when being introduced into the receiving space. The end point is preferably formed by at least one additional web projecting into the receiving space or at least one bulge of the holding parts delimiting the receiving space projecting into the receiving space. Preferably, the part of the holder forming the constriction, in particular a wall delimiting the receiving space and forming the constriction, is designed to be at least partially elastically bendable. Thus, the constriction for passing the section of the surface element to be fixed can be temporarily enlarged and, after passing the section to be fixed, can be reduced again to a smaller, in particular its original, size. The size of the constriction is in particular smaller in the adjustment direction than an extension of the section of the surface element to be fixed, in particular the surface element frame thickness, in this direction. The holder is thus designed for the latching connection to the surface element. The connection of the holder and the surface element is therefore damage-free and secure. An undesired detachment of the holder from the surface element is avoided.The fastening space is preferably a fastening groove which is preferably bounded on three sides and in particular both by the first holding part and by the second holding part. The fastening space is preferably bounded overall on three sides by the holder, in particular the holder parts together. In particular, the part of the holder forming the fastening space forms a clip for clamping connection to the frame. Thus, a releasable connection to the frame, in particular to the web of the frame, is achieved in a simple manner.The holder preferably has a fastening stop delimiting the fastening space, up to which the frame is to be inserted in its insertion direction through an insertion opening of the fastening space opposite the fastening stop. The fastening stop is preferably designed to bear against the frame in the mounted position of the holder. In particular, the fastening stop delimits the fastening space on a central side of the three sides. A defined position of the frame relative to the holder is thus achieved in the mounted position of the holder. In addition, the holder is comparatively simple to mount.In a preferred embodiment, a receiving opening of the receiving space and an insertion opening of the fastening space are arranged on opposite sides of the holder. Preferably, an insertion direction of the surface element to be inserted into the receiving space is arranged opposite to an insertion direction of the frame to be inserted into the fastening space. The ease of assembly of the holder is thus increased.In a further preferred embodiment, the fastening space is bounded on a first side by the first mounting part and on a second side opposite the first side by the second mounting part. The first side and the second side are preferably opposite each other in the adjustment direction. In addition, the first side and the second side are preferably each arranged adjacent to the middle side forming the fastening stop. The frame is to be arranged between the first side and the second side in particular in the adjustment direction. The first holding part is preferably designed for bearing on the outside on the frame. The second holding part is preferably designed for bearing on the inside against the frame. The part of the first holder part forming the first side preferably also forms with its side facing away from the fastening space the connecting region, in particular the part of the holder delimiting the receiving space. A constructionally simple implementation of the adjustability of the holder is thus promoted.Preferably, the first mounting part and the second mounting part can be connected to each other so as to be displaceable in the adjustment direction in order to adapt the fastening space to different frame thicknesses. For displacing the boundaries of the fastening space lying in the adjustment direction, the parts of the holder delimiting the fastening space, in particular the first holder part and the second holder part, are connected to one another such that they can be displaced relative to one another in the adjustment direction in the mounted position of the holder. This achieves a movable connection of the mounting parts to one another in a simple manner.The second mounting part preferably has a holding arm running transversely to the adjustment direction, which in the mounted position of the mounting is designed to engage over the frame on its side facing away from the surface element. Transverse is understood to mean obliquely or vertically. In the mounted position of the holder, the frame is overlapped in particular at least in regions. Thus, a connection to the frame is made in a simple manner.In a preferred embodiment of the invention, a part of the holding arm protrudes relative to a remainder of the holding arm in the direction directed towards the center of the fastening space and is in particular designed to at least partially enclose a seal arranged on the inside of the frame in the mounted position of the holder. The seal is preferably designed as a stop seal for a stop of the window or door leaf on the window frame. The protruding part of the holding arm preferably protrudes increasingly with increasing distance from the rest of the second holding part. In particular, the holding arm is curved or angled in the direction directed toward the center of the fastening space. The holding arm thus hooks on the seal of the frame. The connection of the holder to the frame is particularly secure.In a further preferred embodiment, the holding arm has, on its side facing the fastening space, at least one projection, in particular designed as a rib, for improved connection to the frame. Thus, adhesion between the bracket and the frame can be improved.Preferably, the fastening stop is formed by a connecting portion of the holder in which the first holder part and the second holder part are connected to one another. The connecting portion is formed in particular by a first connecting portion of the first mounting part and a second connecting portion of the second mounting part connected to the first connecting portion. A longitudinal extension of the connecting section preferably runs in the adjustment direction. The mounting is thus of a structurally simple design.Preferably, one of the holding parts forms a guide for the other of the holding parts in the connecting section, in particular wherein the one of the holding parts at least partially surrounds the other of the holding parts. In the connected position, the second holding part preferably engages at least partially around the first holding part. The gripping is preferably effected in the respective preferably present first or second connecting section of the holding part. By means of the encompassing, the connection of the holding parts, which connection is in particular designed as a latching connection, is preferably fixed to one another and an undesired release of the connection is prevented. In particular, at least a part of the enclosing holding part is designed to be elastically bendable for adjusting the holding device. Due to the elastic angle-fitting, this part can free a space for moving the other holding part and thus for adjustment. In this way, a secure connection of the holding parts and a simple adjustability are realized.In a preferred embodiment, one of the holding parts has at least one first latching element formed integrally therewith and the other holding part has a plurality of second latching elements formed integrally therewith for adjustably latching connection to the first latching element. Preferably, the first holding part, in particular the first connecting section, has at least one first latching element, in particular designed as a latching nose. The second holding part, in particular the second connecting section, preferably has a plurality of second latching elements, in particular each formed as a latching nose. Preferably, at least one of the holding parts, in particular both holding parts, has a plurality of first or second latching elements arranged one behind the other in the adjustment direction. In the mounted position of the holder, at least one of the latching elements of one of the holder parts is adjustably latchingly engaged with at least one other of the latching elements of the other holder part. The latching elements preferably prevent a movement of the mounting parts, in particular of the sides delimiting the fastening space, away from one another along the adjustment direction. The latching connection can thus be mounted in a particularly short time and in a simple manner. In addition, this allows particularly rapid and simple adaptation to different frame thicknesses.The holding part with a plurality of second latching elements formed integrally therewith is designed such that it can be curved in particular in the adjustment direction. For this purpose, the second latching elements are arranged on an end of the holding part lying in the adjustment direction. In addition, the holding part preferably has at least one separating aid, which is in particular designed as a notch. The separating aid is arranged in particular in the adjustment direction between two second latching elements. Thus, a separation point of the holding part is marked in a secure manner.The latching elements preferably allow a relative movement of the mounting parts transversely to the adjustment direction. Thus, for simpler mounting of the holder, in a first step, the first holder part and the second holder part can be connected, in particular pushed one inside the other, laterally, that is to say transversely to the adjustment direction. Subsequently, in a second step, the holder can be adapted to the frame thickness by moving the holder parts towards each other in the adjustment direction and an associated adjustment of the latching elements finally. In order nevertheless to ensure a secure connection of the two holding parts, the holding device preferably has centering means for centering the holding parts with respect to one another transversely to the adjustment direction. The centering means can be formed, for example, as a projection formed integrally with one of the mounting parts and as a recess of the other mounting part interacting with the projection for centering.In a further preferred embodiment, the first mounting part and the second mounting part each have at least one first latching plane with at least one first of the respective latching elements and each have at least one second latching plane with at least one second of the respective latching elements. In particular, at least one of the holding parts has a plurality of latching elements per latching plane. The connection of the holding parts to one another is thus particularly secure.Preferably, at least one of the holding parts forms a section for bearing against the frame on a side of the frame lying in the adjustment direction, wherein the section is designed to be elastically bendable, in particular wherein the holding parts can be braced against the frame by means of elastic bending of the section in the mounted position of the holder for clamping connection to the frame. The bracing takes place in particular by elastic bending of the section relative to a further part of the holder. The section is arranged angled in particular towards the frame side before the bracing and is angled at least to a lesser extent towards the frame after the bracing, in particular arranged parallel to the frame. Preferably, an angle of the connecting section forming the fastening stop to the section to be angled before the clamping is less than 90 degrees, preferably 50 to 89 degrees, particularly preferably 60 to 89 degrees, further particularly preferably 70 to 89 degrees. A firm fit of the holder on the frame is thus achieved. Relative movements between the holder and the frame and noises resulting therefrom are reduced.The holder is preferably made of a plastic, for example of polyurethane. As a result, the above-described features which depend on an elasticity of the holder can be realized in a simple manner.The holder is produced in particular by means of deep-drawing or injection molding. The holder can thus be produced comparatively easily and cost-effectively.The sun, insect, rodent, dust and / or pollen protection device according to the invention comprises a surface element for covering a window or a door and at least one holder of one of the above-described embodiments for fastening the surface element to a window frame of the window or the door. Thus, the sun, insect, rodent, dust and / or pollen protection device benefits the advantages described above in connection with the bracket.Further advantages and details of the invention can be seen from the following description of the figures.The figures show schematically: FIG. 1 shows a front view of a window with a sun, insect, rodent, dust and / or pollen protection device and a holder according to the invention, FIG. 2 shows a sectional view of the object from FIG. 1 along line II-II from FIG. 1, FIG. 3 shows a detailed view of the object from FIG. 2 according to detail III from FIG. 2, FIG. 4 shows a perspective view of a further embodiment of a first mounting part of a mounting according to the invention, FIG. 5 is a side view of the first mounting part from FIG. 4 , FIG. 6 shows a perspective view of a further embodiment of a first mounting part of a mounting according to the invention, FIG. 7 is a side view of the first mounting part from FIG. 6 , FIG. 8 shows a perspective view of a further embodiment of a first mounting part of a mounting according to the invention, FIG. 9 is a side view of the first mounting part from FIG. 8, FIG. 10 shows a perspective view of a further embodiment of a first mounting part of a mounting according to the invention, FIG. 11 is a side view of the first mounting part from FIG. 10 , FIG. 12 shows a perspective view of a further embodiment of a second mounting part of a mounting according to the invention, FIG. 13 is a side view of the second mounting part from FIG. 12 , FIG. 14 shows a perspective view of a further embodiment of a second mounting part of a mounting according to the invention, FIG. 15 is a side view of the second mounting part from FIG. 14 , FIG. 16 shows a perspective view of a further embodiment of a second mounting part of a mounting according to the invention, FIG. 17 is a side view of the second mounting part from FIG. 16 , FIG. 18 shows a perspective view of a further embodiment of a second mounting part of a mounting according to the invention, and FIG. 19 is a side view of the second mounting part from FIG. 18.Identically or similarly acting parts are provided with identical reference numerals, provided that they are used. The features and details of the invention described below can also be the subject matter of the invention in combinations other than those shown in the exemplary embodiments.FIGS. 1 and 2 show a window 10 with a window frame 8 and a window sash 13 (cf. FIG. 2 ). A sun, insect, rodent, dust and / or pollen protection device 6, comprising a surface element 4 and in the present case a plurality of holders 2, is attached to the frame 8 by means of the holders 2. In the present case, two holders 2, i.e. a total of eight holders 2, are provided on each circumferential surface element side.FIG. 3 shows in detail one of the holders 2 for fastening the planarly extending surface element 4. the surface element 4 comprises in the present case a covering material embodied as a protective grid 7 and a surface element frame 13 surrounding the protective grid 7. The holder 2 has a connecting region 12 for connecting to the surface element 4 and forms a fastening space 14, into which a section 9 of the window frame 8, in particular a window frame web protruding toward the interior of the window, is to be inserted. The holder 2 has a two-part construction with a separate first holder part 16 and a separate second holder part 18 which is in engagement with the first holder part 16 in the illustrated, mounted position of the holder 2. the first holder part 16 and the second holder part 18 are designed to be adjustable relative to one another in an adjustment direction 22 in order to adapt the fastening space 14 to different frame thicknesses 20. The holder 2 can thus be mounted in a simple manner and without damage and can be flexibly adapted to different frame thicknesses 20.In the present case, the connecting region 12 forms a receiving space 24, into which a section 5 of the planar element 4 is to be inserted. As illustrated, the receiving space 24 is in particular a receiving groove bounded by the first mounting part 16 on three sides 25, 27, 29. The first holding part 16 forms a clip for connection to the surface element 4. This enables damage-free connection of the holder 2 to the surface element 4.The first holding part 16 forms in the present case a receiving stop 26 delimiting the receiving space 24, up to which the planar element 4 is to be inserted in its insertion direction 3 through a receiving opening 32 of the receiving space 24 opposite the receiving stop 26. The surface element 4 thus bears in the mounted position against the receiving stop 26 and in a defined position.The fastening space 14 is in the present case a fastening groove bounded on three sides 15, 17, 19 and by both the first mounting part 16 and the second mounting part 18. Thus, for simple assembly with the frame 8, the holder 2 can be placed with this fastening groove on the web of the frame 8.The fastening space 14 is bounded on its central side 17 by a fastening stop 38 up to which the frame 8 is to be inserted in its insertion direction 30 through an insertion opening 40 of the fastening space 14 opposite the fastening stop 38.The receiving opening 32 of the receiving space 24 and the insertion opening 40 of the fastening space 14 are arranged on opposite sides 42, 44 of the holder 2 in the present case for the simple mounting of the holder 2.The fastening space 14 is bounded on a first side 46 by the first mounting part 16 and on a second side 48 opposite the first side 46 by the second mounting part 18. The extension of the fastening space 14 in the adjustment direction 22 can thus be influenced in a simple manner by the position of the holding parts 16, 18 with respect to one another.The first mounting part 16 and the second mounting part 18 can be connected to one another so as to be displaceable in the adjustment direction 22 in order to adapt the fastening space 14 to different frame thicknesses 20. Thus, the position of the mounting parts 16, 18 relative to each other can be changed in a simple manner.The second mounting part 18 has a holding arm 50 running transversely to the adjustment direction 22, which in the mounted position of the mounting 2 is designed to engage over the frame 8 on its side 52 facing away from the surface element 4. A positive connection of the holder 2 and the frame 8 is thus achieved in a simple manner.A part 51 of the holding arm 50 protrudes relative to a remainder 53 of the holding arm 50 in the direction 55 directed toward the center of the fastening space 14. In particular, the part 51 is designed to at least partially enclose a seal 54 arranged on the inside of the frame 8, in particular a stop seal for the window sash 11, in the mounted position of the holder 2. In the present case, the part 51 of the holding arm 50 is curved towards the interior of the fastening space 14. The connection of holder 2 to frame 8 is thus particularly secure.The security of the connection of the holder 2 and the frame 8 can be further improved in that the holding arm 50, as shown in FIGS. 12 and 13, has at least one protrusion 58 designed as a rib on its side 56 facing the fastening space 14 for improved connection to the frame 8. Alternatively or additionally, the second holding part 18 can have an additional bend 59 for at least partially engaging behind the seal 54. In the present case, the bend 59 is designed as a wall arranged at one end of the holding arm 50 and directed towards the seal 54 (cf. FIG. 3 ).The fastening stop 38 shown in FIG. 3 is formed by a connecting section 60 of the holder 2, in which the first holder part 16 and the second holder part 18 are connected to one another in a latching and adjustable manner. The connecting section 60 extends with its longitudinal extension in the adjustment direction 22. one of the mounting parts 16, 18 forms a guide for the other of the mounting parts 16, 18 in this connecting section 60, wherein the one of the mounting parts 16, 18 partially encompasses the other of the mounting parts 16, 18 for secure connection to one another. In the present case, the second holding part 18 engages around the first holding part 16, in particular also second latching elements 64 of the first holding part 16 which are in engagement with the second holding part 18, in the connecting section 60.One of the holding parts 16, 18, in the present case the second holding part 18, has at least one first latching element 62 formed integrally therewith. For adjustably latching connection to this first latching element 62, the other of the holding parts 16, 18, in the present case the first holding part 16, has a plurality of second latching elements 64 formed integrally therewith. Thus, depending on which of the second latching elements 64 is in engagement with the first latching element 62, different positions of the mounting parts 16, 18 with respect to one another and thus different extents of the fastening space 14 in the adjustment direction 22 can be realized.At least one of the holding parts 16, 18 forms a section 70 for bearing against the frame 8 on a side 72 of the frame 8 lying in the adjustment direction 22, wherein the section 70 is designed to be elastically bendable. For simple bending, the section 70 is connected to the rest of the holding part 16 in the present case via a circular segment- or circular arc-shaped bending section 73. The mounting parts 16, 18 can thus be braced against the frame 8, in particular in the mounted position of the mounting 2, for clamping connection to the frame 8, by means of elastic bending of the section 70. For this purpose, for example, by manually compressing the holding parts 16, 18 in the adjustment direction 22, an angle 80 between section 70 and connecting section 60 can be increased, and at the same time an angle between section 70 and the side 72 of the frame 8 can be reduced. The connection is thus reduced in movement and noise and is comparatively secure.FIGS. 4 and 5 show an embodiment of a first holding part 16 with a narrow point 36 of the receiving space 24 for fixing the planar element 4 (cf. FIG. 3 ) in the mounted position. The constriction 36 is formed by bulges 37 of the parts of the first holding part 16 delimiting the receiving space 24. The bulges 37 are directed towards the interior of the receiving space 24 and narrow the receiving space 24 in regions. Thus, the surface element 4, which in sections has an extension exceeding the size of the constriction 36 in the adjustment direction 22, in particular surface element frame thickness, in this direction, is held in the mounted position by the bulges 37 in the receiving space 24. The surface element frame 13 is thus held in the receiving space 24.Alternatively or additionally to the embodiment shown in FIGS. 4 and 5, the constriction 36, as shown in FIGS. 6 and 7, can be formed by webs 39 projecting into the receiving space 24. The webs 39 are inclined in the insertion direction 3 of the surface element 4, so that insertion of the surface element 4 is facilitated and detachment of the first holding part 16 from the surface element 4 counter to the insertion direction 3 is made more difficult.The holding part 16, 18 comprising the plurality of second latching elements 64 formed integrally therewith, in the present case the first holding part 16, is designed such that it can be moved in the adjustment direction 22. For this purpose, the second latching elements 64 are arranged at an end of the first holding part 16 lying in the adjustment direction 22. In addition, the first holding part 16 in the present case has at least one separating aid 74 designed as a notch. The separating aid 74 is arranged between two second latching elements 64 in the adjustment direction 22. Thus, the first holding part 16 can be easily shortened at the location marked by the separating aid 74. The holder 2 is thus flexibly adaptable to rather small frame thicknesses.FIGS. 8 and 9 show a further embodiment of a first holding part 16 with an additional stiffening base 34 arranged parallel to the receiving stop 26 and stiffening the receiving stop 26. Thus, the part of the first holding part 16 forming the receiving space 24 is particularly stable. Alternatively or additionally, the wall delimiting the outer side 29 of the receiving space 24 facing away from the frame 8 (cf. FIG. 3 ) in the mounted position has an increased wall thickness relative to the remaining holder 2.As shown in FIGS. 10 and 11 and 14 to 19, the first holding part 16 and the second holding part 18 each have at least one first latching plane 66 with at least one first of the respective latching elements 62, 64 and at least one second latching plane 68 with at least one second of the respective latching elements 62, 64. The connection of the holding parts to one another is thus particularly secure.FIGS. 10 and 11 show an embodiment of a first holding part 16 with a central web 76 running in the adjustment direction 22 and two latching planes 66, 68 arranged on opposite sides of the central web 76.In addition, the first holding part has a support element 78 formed integrally therewith and in particular formed as a web for supporting on the frame 8 (cf. FIG. 3 ) on its side parallel to the adjustment direction 22. Thus, preferably both holding parts 16, 18 have a defined stop on the frame 8 transversely to the adjustment direction 22.In the embodiment of a second mounting part 18 shown in FIGS. 14 and 15, a first latching element 62 is provided for each latching plane 66, 68. For this purpose, the second holding part 18 has two walls which are arranged parallel to one another and which each form one of the latching planes 66, 68. The first latching elements 62 of the latching planes 66, 68 face one another.
