[0003] Mounting element for attaching building components via a keyhole-shaped recess
[0004] 5
[0005] The present invention generally relates to a mounting element for fastening components via a keyhole-shaped receptacle, as well as a corresponding mounting system comprising a mounting element and a fastening element, or a system comprising a component for arrangement on a substrate with a plurality of mounting systems according to the invention.
[0006] When installing building components, such as facade panels, on a substrate, mounting points, such as screws or other fasteners, can be attached to the substrate. The facade panels can then be positioned at these mounting points, for example, using the keyhole-shaped recesses within them. A common problem is that the mounting points are often concealed by the building components during installation and are therefore not visible to the installer. This means that the installer frequently has to blindly place the building components onto the mounting points. The installer must shift the building component relative to the substrate to find the correct point and angle of contact between the concealed mounting points and the keyhole-shaped recesses.Especially with large building components, such as facade panels or support profiles, a large number of mounting points are often used to secure the component, making it difficult to locate them by feel. The sheer number of mounting points isn't the only problem. Inaccuracies during the installation process can also cause the mounting points to deviate slightly from their intended position in the substrate. This can be particularly problematic with a large number of mounting points, as these inaccuracies can compound. This makes it difficult to find the correct relative position of mounting points and keyhole-shaped recesses by feel and can also lead to stress within the component. If the component is subjected to stress during the installation process, this can result in damage to the component or visual defects (e.g., bumps or dents).
[0007] The object of the present invention is therefore to overcome the aforementioned disadvantages and to provide a mounting point that simplifies the relative arrangement of a component on a substrate.
[0008] This problem is solved by an assembly element, an assembly system, and a system comprising a component and an assembly system according to the invention, as described in the independent claims. Preferred and advantageous embodiments are described in the dependent claims and in the following description.
[0009] A mounting element according to the invention for the relative arrangement of a component on a substrate comprises a sleeve-shaped body and a holding area. The sleeve-shaped body has a channel for receiving a fastening element. A fastening element can be, for example, a screw, a nail, a bolt, a dowel, or the like, as well as a combination of two or more of the aforementioned examples. The sleeve-shaped body preferably has a longitudinal extension, wherein the channel for receiving a fastening element is aligned along the longitudinal extension. The sleeve-shaped body is preferably cylindrical. However, the sleeve-shaped body can also have another geometric shape, for example, a (preferably right) prism, such as a rectangular or square column, a triangular or polygonal prism.Such prisms typically have a lateral surface, a top surface, and a bottom surface, with the channel for receiving a fastener preferably oriented from the top surface of the prism to the bottom surface. Furthermore, the channel preferably has an opening at each of its ends. A fastener inserted into the channel can be accessed through these openings. For example, a tool can protrude through the opening into the channel to reach the fastener. If the fastener is a screw, a tool can thus reach a drive mechanism at the screw head. Additionally, the fastener can protrude from one or both openings. This allows, for example, the fastener to pass through the channel and protrude through one of the openings to reach the substrate in which the fastener is to be anchored.Alternatively, the fastener can protrude from the opening on both sides of the channel. In this case, one head of the fastener, when installed, can rest against the outside of the channel opening furthest from the substrate. Furthermore, the channel can have a diameter adapted to the dimensions of the fastener. One of the two open ends of the channel can be tapered relative to the channel's diameter, allowing the head of the fastener to rest against the tapered end when the fastener is used to secure the mounting element to the substrate or a structural component. The channel can also have one or more internal projections that interact with the fastener to limit its movement relative to the mounting element when installed.In one embodiment, one or more projections can be designed in such a way that they not only limit the range of motion of the fastening element, but also form the narrowing of the channel against which the head of the fastening element can rest.
[0010] The holding area can be located on the sleeve-shaped body of the mounting element, or the sleeve-shaped body can transition gradually or continuously into the holding area.
[0011] The retaining area of the mounting element is adapted to engage in a keyhole-shaped receptacle. A keyhole-shaped receptacle, sometimes also called a keyhole bore or keyhole recess, is a receptacle that has a section with a larger diameter and a section with a smaller diameter. An example of a keyhole-shaped receptacle is shown in Figure 1, where the section with the larger diameter is labeled with diameter d and the section with the smaller diameter is labeled with diameter d2, i.e., d2 > d2. A clearance is preferably located behind the section of the keyhole-shaped receptacle that has the smaller diameter (d2).If the keyhole-shaped recess is located in a substrate, a space is created behind the smaller-diameter section of the recess. This space has a diameter approximately equal to or greater than that of the larger-diameter section. This can be achieved, for example, by creating a blind hole in the substrate and covering it with a plate containing a keyhole-shaped opening. The two differently sized sections forming the keyhole shape of this opening restrict access to the blind hole, creating the aforementioned space behind the keyhole-shaped recess.If the keyhole-shaped receptacle is located in a support profile, the free space into which the holding area of a mounting element can engage results, for example, from the fact that the support profile is thinner than the holding area is long, so that the holding area can extend through the receptacle and lie against a back side of the support profile like a hook and can be secured against slipping out of the keyhole-shaped receptacle by the section with the smaller diameter.
[0012] In this way, a keyhole-shaped receptacle allows the holding area of a mounting element to be inserted into the keyhole-shaped receptacle via the area with the larger diameter, moved within the receptacle to the area with the smaller diameter, and thus anchored in the keyhole-shaped receptacle. For this to work, the maximum diameter of the holding area is smaller than the larger diameter of the keyhole-shaped receptacle, but larger than the smaller diameter of the keyhole-shaped receptacle.Preferably, the retaining area also has a geometry adapted to the geometry of the keyhole-shaped receptacle. In this context, "adapted" means that the adapted geometry allows displacement from the area of the keyhole-shaped receptacle with the larger diameter to the area with the smaller diameter, while simultaneously providing a secure fit in the area with the smaller diameter because the retaining area cannot slip out of the receptacle in the area with the smaller diameter. This can be achieved, for example, by the retaining area having a recess or step that can be inserted into the receptacle in the area of the keyhole-shaped receptacle with the larger diameter, but cannot be guided out again in the area of the keyhole-shaped receptacle with the smaller diameter.In other words, the indentation or step can reach through the keyhole-shaped recess and, like a hook, prevent it from slipping out or being pulled out at its rear.
[0013] According to the invention, the holding area includes an assembly aid. The assembly aid is designed to facilitate insertion into the keyhole-shaped receptacle. The assembly aid can, for example, be formed from a section of the holding area that projects from the sleeve-shaped body of the mounting element, the diameter of which decreases with increasing distance from the sleeve-shaped body. Regardless of whether the holding area is located on the sleeve-shaped body or whether the sleeve-shaped body transitions gradually or continuously into the holding area, it can be said that the holding area—and thus the assembly aid—projects from the sleeve-shaped body.The maximum diameter of the mounting aid is smaller than the diameter of the larger, keyhole-shaped receptacle, allowing the mounting aid to slide into the larger diameter section. The change in diameter from its smallest to its maximum can be formed, for example, by a conical section—in other words, the mounting aid has a conical section. Alternatively, the change in diameter can be gradual.
[0014] Preferably, the holding area features a transition from the maximum diameter of the mounting aid to the sleeve-shaped body, formed by a step. This step creates a transition from the maximum diameter of the mounting aid to the comparatively smaller diameter of the sleeve-shaped body. This allows the holding area to slide into the keyhole-shaped receptacle. This transition, or step, secures the holding area within the smaller diameter portion of the keyhole-shaped receptacle. According to the invention, the mounting element is formed from two or more parts. For illustrative purposes, a two-part embodiment is assumed below; however, this can be abstracted to any multi-part embodiment within the scope of a person skilled in the art.For example, the sleeve-shaped body and the retaining area can each form a part in the sense of a two-part design. Likewise, a first part can be formed from a first section of the sleeve-shaped body and a first section of the retaining area, and a second part from a second section of the sleeve-shaped body and a second section of the retaining area. This two-part design of the mounting element allows access to the internal channel of the sleeve-shaped body, so that a fastening element can be manufactured separately from the mounting element and inserted into it.
[0015] The mounting element according to the invention simplifies insertion into a keyhole-shaped receptacle by means of the mounting aid provided by the holding area. For example, the decreasing diameter of the mounting aid can make it easier to locate the keyhole-shaped receptacles in a blind installation, since an object with a small diameter (e.g., the tip of a cone) is initially inserted into the keyhole-shaped receptacle, and the mounting aid then slides deeper into the keyhole-shaped receptacle by means of its increasing diameter. The initially small diameter of the mounting aid thus increases the probability of the mounting aid being correctly positioned in the keyhole-shaped receptacle during a blind installation.At the same time, the holding area offers secure protection against slipping out of the keyhole-shaped recess, for example through the increasing diameter of the mounting aid, which results in a large contact area of the holding area in the keyhole-shaped recess when mounted.
[0016] Furthermore, as described above, stresses can arise when a large number of mounting elements are used to fasten large components if the relative positions of the mounting elements anchored in the substrate exhibit inaccuracies. These inaccuracies can be compensated for with the mounting elements incorporating the mounting aids according to the invention. For example, if one or more of a large number of mounting elements exhibit minor deviations from an intended fastening position (i.e., ideal positioning), the simplified location of the keyhole-shaped receptacles using the mounting aids of the mounting elements can cause the holding areas to slide into the appropriate positions and be centered by their respective mounting aids, thereby compensating for minor deviations from ideal positioning.
[0017] Preferably, the mounting element according to the invention is anchored in the substrate, and a building element (e.g., a facade panel) having keyhole-shaped recesses is slid onto the mounting elements according to the invention. However, the present invention also encompasses anchoring the mounting elements according to the invention to the building element and creating the keyhole-shaped recesses in the substrate. For this purpose, for example, an elongated bore can be created in the substrate, and this bore can be covered by a plate having a keyhole-shaped bore. In this context, it should be noted that the term "substrate" is not limited to substrates in the sense of masonry. Support profiles or frames are also considered substrates within the meaning of the present invention, whereby support profiles or frames can also constitute building elements in some embodiments.If the substrate is a support profile, for example made of bent metal, the keyhole-shaped hole can be created directly in the metal.
[0018] Furthermore, the inventive design of the mounting element enables a simple setting process of the mounting element either on the substrate or on the component. Due to its geometry, the mounting aid is sized appropriately to allow the user to hold the mounting element in place during the setting process. The sleeve-shaped body with the channel for receiving a fastener allows the fastener to rotate freely within the channel. This enables the fastener to be set in rotation independently of the mounting element, for example, when the fastener is screwed into a substrate. It is known, for instance, that self-drilling or self-tapping fasteners tend to wobble during the setting process, which can cause the fastener to slip during installation.Since the fastener is set into rotation during the setting process, the user cannot hold the fastener itself and secure it in a position laterally to the substrate to prevent wobbling. However, when using the mounting element according to the invention, the user can hold the mounting element and secure it laterally to the substrate, while the fastener is freely rotatable within the channel of the mounting element and guided by the orientation of the channel, which can reduce or prevent wobbling of the fastener during the setting process.
[0019] Further preferred embodiments of the mounting element according to the invention are described below.
[0020] In a preferred embodiment, the mounting element is made of at least one type of plastic. In a preferred embodiment, the holding area or the mounting aid of the holding area can be made of a softer plastic, and the sleeve-like body can be made of a metal or a harder plastic. If the holding area as a whole or the mounting aid is made of a softer, for example, elastically deformable, plastic, inaccuracies in the arrangement can be compensated for to a particularly high degree, since the softer material allows it to be easily deformed when finding the appropriate contact position between the mounting aid and the component to be mounted. Furthermore, a softer plastic can help to decouple the component attached to the substrate with the mounting element relative to the substrate and, for example, reduce thermal and / or acoustic transmission.
[0021] In a preferred embodiment, a first part of the two or more parts of the mounting element comprises a first section of the sleeve-shaped channel and a first section of the holding area, and a second part of the two or more parts of the mounting element comprises a second section of the sleeve-shaped channel and a second section of the holding area. The first part of the mounting element can be hinged to the second part of the mounting element. A hinge allows the mounting element to be configured as a two-part or multi-part assembly, while still maintaining a single-piece design. The mounting element can be opened via the hinge, providing access to the channel within the sleeve-shaped body and thus allowing the insertion of a fastening element.In this case, the holding area preferably has an opening located at a position on the axis of the fastener when the fastener is inside the sleeve-shaped body. This ensures that the fastener drive remains accessible to a tool, even when the fastener is inside the mounting element. The opening can, for example, be referred to as a tool opening. The opening can be formed by recesses in the first and second parts of the mounting element, which create the opening when they are folded together.
[0022] As an alternative to a hinge connection, the first and second parts of the mounting element can also be connected to each other via a plug connection.
[0023] In an alternative embodiment, a first part of the two or more parts of the mounting element comprises the sleeve-shaped body, and a second part of the two or more parts of the mounting element comprises at least a section of the retaining area; that is, the second part can comprise the entire retaining area or only a section of it. The first part of the mounting element can be connected to the second part of the mounting element via a plug connection. In other words, the retaining area, or at least a section of it, can be plugged onto the sleeve-shaped body. In this case, a fastening element can, for example, be inserted into the channel of the sleeve-shaped body before the second part of the mounting element is plugged onto the sleeve-shaped body.In other words, the entire holding area can be fitted onto the sleeve-shaped body, or the first part of the mounting element comprises the sleeve-shaped body and a section of the holding area, and the second part of the mounting element comprises another section of the holding area, so that the sections of the holding area are assembled when the first and second parts of the mounting element are fitted together. Again, in this case, the holding area preferably has an opening, which can be called a tool opening, located at a position on the holding area that lies on an axis with the fastener when the fastener is inside the sleeve-shaped body. This ensures that the drive of the fastener remains accessible to a tool even when the fastener is inside the mounting element.
[0024] In a preferred embodiment, the channel of the sleeve-shaped body has two or more internal projections. These internal projections can serve to guide a fastening element within the channel. For example, the fastening element can be aligned—e.g., centered—by the projections. The projections can extend completely inside the channel or be formed in sections. Depending on the design of the projections, a mounting element according to the invention can be configured either as a sliding-point sleeve or as a fixed-point sleeve. While a fixed-point sleeve holds the internal fastening element firmly in position and allows virtually no relative movement between the fastening element and the mounting element, in a sliding-point sleeve the fastening element is arranged to be movable within limits, so that lateral movement (i.e., displacement) between the mounting element and the fastening element is permitted.The latter allows for the compensation of stresses that arise, for example, from thermal deformation of a component attached to the mounting element. In contrast, the projections in the case of a fixed-point sleeve are designed to be robust in order to bear the load from the component's own weight. In the case of a sliding-point sleeve, the projections are equipped with one or more predetermined breaking points to ensure they break off when stresses occur.
[0025] In a preferred embodiment, the sleeve-shaped body has a collar positioned at a distance from the mounting aid. Preferably, the distance between the collar and the mounting aid is greater than the thickness of the material in which the keyhole-shaped receptacle is formed, for example, the support profile or a plate that is placed onto a bore. This allows the smaller diameter portion of the keyhole-shaped receptacle to slide into a space formed between the mounting aid and the collar. The collar thus provides protection between the substrate and the component. Such a collar is particularly advantageous when the mounting element is made of plastic, as the plastic can dampen vibrations that may occur due to stresses in the component, for example, as a result of thermally induced deformation.Such a collar is therefore particularly advantageous in the case of sliding point sleeves. This makes such an embodiment especially suitable for improving the acoustic properties of facade panel fixings. The collar according to the invention can be formed circumferentially or in sections. To improve the seating of the mounting element on the substrate, the collar can have one or more projections that extend from the mounting element on the side where the collar rests against the substrate when installed. In other words, the projections can extend from the collar in the direction in which the fixing element protrudes from the mounting element to penetrate the substrate. The same applies to the seating on the building element when the mounting element is attached to the building element with the fixing element instead of to the substrate.The protrusions can deform during the installation of the mounting element on the substrate / component, thereby improving the fit of the mounting element. This can occur, for example, when the protrusions are pressed against the substrate / component by pressure during tightening of the fastener. The protrusions can extend around the entire collar, across the collar, or form a pattern on the collar.
[0026] The features of the preferred embodiments described above are not exclusive. Instead, they can be combined, provided they do not contradict each other.
[0027] The aforementioned problem is also solved by a mounting system according to the invention. The mounting system comprises a mounting element according to one of the embodiments described above.
[0028] Furthermore, the mounting system comprises a fastening element. In the present invention, the fastening element preferably comprises a head, a shaft, and a drill tip. The head and drill tip are typically arranged at opposite ends of the shaft. The extension of the fastening element between the head and drill tip can define an axis. When the fastening element is inserted into a substrate, this axis can typically be substantially perpendicular to the substrate. This axis can run in the direction of installation. Furthermore, the shaft of the fastening element has a projection. The projection can be adapted to interact with internal projections of the channel of the sleeve-shaped body and to form a positive-locking connection, which results in the lateral movement of the fastening element relative to the mounting element being limited or completely prevented.In a preferred embodiment, the projection is ring-shaped and arranged on the shaft of the fastening element.
[0029] The head of the fastener preferably has a tool holder. The fastener preferably has a thread between the drill tip and the projection. Furthermore, the fastener preferably has an unthreaded area between the thread and the projection.
[0030] Preferably, the holding area has an opening located at a position on the axis of the fastening element when the fastening element is inside the sleeve-shaped body. This allows access to the fastening element's drive mechanism even when the fastening element is inside the sleeve-shaped body.
[0031] The aforementioned problem is also solved by a system according to the invention. The system according to the invention comprises a component for mounting on a substrate and a plurality of the mounting systems described above. Either the keyhole-shaped receptacle is located in the component to be mounted on the substrate, and the fastening element is adapted to be anchored in the substrate, or the keyhole-shaped receptacle is located in the substrate, and the fastening element is adapted to be anchored in the component to be mounted on the substrate. In a preferred embodiment, which serves to fasten components relative to a substrate, the plurality of mounting systems of the system includes both mounting systems whose mounting elements are designed as fixed-point sleeves and mounting systems whose mounting elements are designed as sliding-point sleeves.Preferably, one mounting system equipped with a fixed-point sleeve is provided for each component to be fastened, while the other mounting systems used to fasten the respective component are equipped with a sliding-point sleeve. The particular advantage of this is that the mounting system with the fixed-point sleeve securely fixes the component at one point, and the design of the other mounting systems as sliding-point sleeves allows stresses that occur during thermally induced deformation to be compensated for by permitting a small degree of movement of the components relative to the substrate.The use of both fixed and sliding point sleeves, instead of solely sliding point sleeves, ensures that the fixed point sleeves define a structure that maintains a visually appealing appearance and prevents the components from shifting unintentionally or even becoming wedged together. Of course, a professional will recognize that the use of both sliding and fixed point sleeves is not limited to cases where only a single fixed point sleeve is used per component. Rather, the geometry of the components or the nature of the substrate may necessitate the use of more than one fixed point sleeve per component.

[0041] Figure 10 shows a mounting method for the relative arrangement of a support profile with a keyhole bore on a mounting element that is anchored in a substrate;
[0042] Figure 11 illustrates the relative positioning of the mounting element and its insertion into a keyhole-shaped receptacle in the assembled state. Figure 1 shows examples of a keyhole-shaped receptacle 100a, loob in various orientations, the orientation depending on whether the receptacle is located in the substrate or in the component to be attached to the substrate. In both examples in Figure 1, the keyhole-shaped receptacle 100a, loob has a region 105 with a larger diameter and a region 110 with a smaller diameter d2.
[0043] Figure 1(a) shows the case where the keyhole-shaped receptacle 100a is located in the component that is to be mounted on mounting elements attached to the substrate. In this case, the mounting aid of the mounting element attached to the substrate can be inserted into the area 105 with the larger diameter (d) and the component can be suspended from the mounting element by gravity. Gravity causes the component to shift relative to the mounting element, and the keyhole-shaped receptacle 100a slides along the holding area of the mounting element, ultimately moving the holding area of the mounting element into the area 110 of the keyhole-shaped bore, which has the smaller diameter (d2).In comparison, Figure 1 (b) shows the case where the keyhole-shaped receptacle 100b is located in the substrate, which is why the holding area of the mounting element attached to the component slides into the area 100b of the keyhole-shaped receptacle, which has the smaller diameter (d2), due to gravity.
[0044] Figure 2 shows an embodiment of a mounting element 200a according to the invention in various views, wherein the mounting element 200a is pluggable. Figures 2(a) to (c) show various views of the assembled mounting element 200a with an inserted fastening element (cf. fastening element 300 in Figure 6), and Figures 2(d) and (e) show views of the disassembled mounting element 200a. Figure 2(d) shows a first part 205a of the mounting element 200a, which has the sleeve-shaped body and a first section of the holding area 211, and Figure 2(e) shows a second part 210a of the mounting element 200a, which has a second section of the holding area 211. The mounting element 200a in Figure 2 has a sleeve-shaped body with a channel (not shown in Figure 2) for receiving a fastening element and a holding area 211.
[0045] The sleeve-shaped body has a collar 230 with a plurality of projections 235. In this embodiment, the collar 230 forms a plate from which the plurality of projections 235 extend. The projections 235 serve to be compressed between the collar 230 and the substrate / component during the mounting of the mounting element 200a to a substrate or component, in order to improve the fit.
[0046] The retaining area 211 has a section 215, which is conical in shape. This section 215 has a variable diameter. The cone has its largest diameter at a point 255 located on the sleeve-shaped body. At this point 255, the retaining area 211 transitions into the sleeve-shaped body of the mounting element via a step. The cone projects from the sleeve-shaped body in the opposite direction to the projections 235 of the collar 230 and has its smallest diameter at a point furthest from the sleeve-shaped body. At the point of smallest diameter (i.e., at the rear end of the mounting element), the cone has an opening 290 through which access to the internal fastening element 300 can be obtained. Figure 2(b) shows a top view of the rear end of the mounting element.As can be seen in this partial illustration, a drive 370 of the fastening element 300 can be accessed through the opening 290 and the fastening element 300 can be set in rotation via a setting tool.
[0047] In the assembled state shown in Figures 2 (a) and (c), it can be seen that the mounting element 200a has a recess 250 between the collar 230 and the retaining area 211. A boundary of a keyhole-shaped receptacle can slide into this recess 250 when the retaining area 211 is inserted sufficiently far into the keyhole-shaped receptacle 100a, 100b.
[0048] Figures 2(d) and (e) show the embodiment of the mounting element 200a of Figure 2 in a disassembled or unassembled state. A first part 205a of the mounting element 200a is shown in Figure 2(d), wherein this part 205a comprises the sleeve-shaped body and a first part 212 of the retaining area 211, the collar 230 projecting from a first end of the sleeve-shaped body and the first part 212 of the retaining area 211 projecting from a second end of the sleeve-shaped body. In this case, the first part 212 of the retaining area 211 forms a projection that extends circularly from the sleeve-shaped body. A second part 210a of the retaining area 211, shown in Figure 2(e), can be slid onto this projection like a cap.Preferably, the cap has projections that engage like hooks behind the first part 212 of the holding area 211 and snap into place like a snap fastener when the second part 210a of the holding area 211 is pushed onto the first part 212 of the holding area 211.
[0049] Before the second part 210a of the retaining area 211 is slid onto the first part 212 of the retaining area 211, a fastening element 300 can be inserted into the channel. Preferably, the fastening element has a head 320 with a comparatively large diameter, which bears against the rear end of the channel or the first part 212 of the retaining area 211 from the outside. The rear end of the channel or the first part 212 of the retaining area 211 forms a support for the head 320 of the fastening element 300. If the mounting element 200a is designed as a sliding sleeve, the head 320 can slide over this support if the component deforms. A preferred embodiment of the fastening element 300 is shown in Figure 6 and is described in more detail in connection with this figure.
[0050] Figure 3 shows an alternative embodiment of a mounting element 200b according to the invention in various views, wherein the mounting element 200b is pluggable. Figures 3(a) to (c) show various views of an assembled mounting element 200b with the fastening element 300 inserted, and Figures 3(d) and (e) show views of a disassembled mounting element 200b, wherein Figure 3(d) shows a first part 205b of the mounting element 200b with the fastening element 300 inserted, and Figure 3(e) shows a second part 210b of the mounting element 200b.
[0051] In the assembled state of Figures 3 (a) to (c), the external shape of this embodiment of the mounting element 200b is comparable to the external shape of the embodiment 200a shown in Figure 2. The embodiments of Figures 2 and 3 differ in the way in which the inner channel 220 of the sleeve-shaped body is accessible for inserting the fastening element 300 – in the case of the embodiment of Figure 2, the fastening element 300 can be inserted into the inner channel through an opening in the inner channel when the second part 210a of the mounting element has been removed (cf. Figure 3).Figure 2(d)), whereas in the embodiment of Figure 3, the inner channel 220 of the sleeve-shaped body is accessible lengthwise, and the fastening element 300 can be inserted lengthwise (wholly or partially) into the inner channel 220, as long as the first part 205b and the second part 210b of the mounting element are not connected to each other (see Figure 3(d)). Apart from the accessibility of the channel 220 for inserting the fastening element 300, the (external) geometry of the respective mounting elements 200a, 200b can be comparable or identical, so that a further detailed description of the components and features is omitted.
[0052] Unlike the embodiment shown in Figure 2, where the second part 210a of the mounting element 200 (i.e., Figure 2(e)) formed exclusively a section of the retaining area 211, the first part 205b of the mounting element shown in Figure 3 is formed from a first section of the sleeve-shaped body and a first section of the retaining area 211, and the second part 210b is formed from a second section of the sleeve-shaped body and a second section of the retaining area 211. In the embodiment shown, the two parts of the mounting element 200b have pins and recesses that can interlock when the two parts 205b, 210b are assembled. It is possible for one of the two parts 205b, 210b to have only pins, while the other part has only recesses.Alternatively, the two parts can each have pins and recesses, the number of each pin and recess of the two parts 205b, 210b being coordinated in such a way that the two parts 205b, 210b can be connected to each other. In the embodiment shown in Figures 3(d) and (e), for example, the part 205b shown in Figure 3(d) may have only pins and the part 210b shown in Figure 3(e) may have only recesses, or the parts 205b and 210b shown in Figures 3(d) and (e) may have a pin at position 260, 200" shown above in the respective image and a recess at position 200', 260"' shown below in the image - in other words, the first part 205b and the second part 210b may be identical - so that joining the parts in this case also results in a pin meeting a recess.
[0053] Figure 4 shows an alternative embodiment of a mounting element 200c according to the invention in various views, wherein the mounting element 200c is foldable. Figures 4(a) to (c) show different views of a folded mounting element 200c with the fastening element 300 inserted, and Figure 4(d) shows a view of an unfolded mounting element 200c with the fastening element 300 inside.
[0054] In the folded state shown in Figures 4 (a) to (c), the external shape of this embodiment of the mounting element 200c is comparable to the external shape of the embodiments 200a and 200b shown in Figures 2 and 3. Only the accessibility of the channel 220 for inserting the fastening element 300 differs from the other mounting elements 200a and 200b, so a further detailed description of the components and features is omitted.
[0055] Unlike the embodiment shown in Figures 2 and 3, embodiment 200c of Figure 4 is formed in one piece and can be folded open instead of being made in two pieces and pluggable together. In the folded state (see Figures 4 (a) to (c)), the folding mechanism can be indicated by a seam 270.
[0056] The embodiment shown in Figure 4 does not depict any pins, recesses, projections, or the like that could be used to secure the mounting element 200c in its folded state against unfolding. Generally, such a securing mechanism is unnecessary, as the slight deformation that occurs when the mounting element 200c is inserted is sufficient to keep it closed. If a foldable mounting element 200c has a collar 230 with deformable projections 235 as shown in Figure 4, these can improve the fit through deformation and thus also prevent unintentional unfolding. Alternatively, securing mechanisms can be provided. For example, a pair consisting of a pin and a recess as described in connection with Figures 3(d) and (e), one or more hooks, or an adhesive or welded connection are conceivable.Preferably, in all embodiments, the insertion of the fastening element into the mounting element and the assembly of the mounting element are carried out before delivery to the user. In the case of the embodiment described in Figure 4, a pin, hook, adhesive, or welded connection may be preferred to secure the assembled mounting element against unintentional opening during transport.
[0057] Figure 5 shows representations of various embodiments of a mounting element 200a, 200b, 200c, 2ood according to the invention with an internal fastening element 300, wherein the illustrated mounting elements 200a, 200b, 200c, 2ood each have a collar 230 with one or more projections 235 arranged thereon, which improve the seating of the mounting element 200a, 200b, 200c, 2ood when anchoring it in the substrate. Here, Figures 5 (a) and (b) correspond to embodiment 200a from Figure 2, Figures 5 (c) and (d) to embodiment 200b from Figure 3, and Figures 5 (e) and (f) to embodiment 200c from Figure 4. Embodiment 2ood of Figures 5 (g) and (h) is a modification of the embodiment from Figure 2 or Figures 5 (a) and (b) with a circumferential projection instead of a circumferential projection in combination with transverse projections.Although the embodiments shown in Figure 5 each show a collar 230 with projections 235, the person skilled in the art recognizes that the invention also includes embodiments with a collar 230 but without projections, in particular if the person skilled in the art wishes to use the advantages of the collar as a support for a sliding movement of the component relative to the substrate in the case of a sliding point sleeve, but wishes to do without the deformation of projections to improve the fit.
[0058] Figure 6 is a detailed perspective view of the fastening element 300, already shown in Figures 2 to 5, as it can be used within the scope of the present invention. The fastening element 300 has a shank 310 and a head 320. The fastening element 300 also has a drill tip 330, which is configured to drill a hole in a substrate. A projection 340 is preferably arranged on the shank 310 of the fastening element 300.
[0059] The embodiment of the fastening element 300 shown in Figure 6 has a thread 350 on the shaft 310 after the drill tip 330 and a threadless area 360 is located between the thread 350 and the projection 340.
[0060] The head 320 of the fastening element 300 is designed to provide a bearing in the mounting element according to the invention, for example at the rear end of the inner channel 220 of the sleeve-shaped body of the mounting element. The head 320 also has a drive 370, which can also be referred to as a tool holder.
[0061] The fastening element 300 shown in Figure 6 can be used with all disclosed embodiments. The fastening systems shown in Figures 2 to 6 and 8 to 11 are identical to the fastening element shown in Figure 6 or differ only slightly. However, those skilled in the art will recognize that the illustrated embodiments of the mounting element can also be used with other fastening elements.
[0062] Figure 7 shows an assembly aid 2ood, 2ooe according to the principles of Figure 5 (g) in the embodiments as (a) fixed point sleeve and as (b) sliding point sleeve.
[0063] In the case of the sliding point sleeve in Figure 7(a), the head 320 of the fastening element 300 is not positively engaged at the rear end of the inner channel 220 of the sleeve-shaped body, but can rest on the sleeve-shaped body in the region of the rear opening of the channel and is displaceable on this support relative to the mounting element 2ood. At the front end of the channel, projections 28od are provided which can initially guide the fastening element to ensure proper positioning during the assembly process. However, due to a tapering of the material, these projections 28od have a predetermined breaking point which can break under stress, for example, due to thermally induced deformation, so that the fastening element is not positively engaged, but is supported relatively within the mounting element.In the case of the fixed-point sleeve in Figure 7(b), the diameter of the channel of the sleeve-shaped body of the mounting element is dimensioned such that the projection 340 of the fastening element 300, as shown in Figure 6, sits almost form-fit in the channel 220. In other words, the inner walls of the inner channel 220 can be reinforced by their thickness and thus form a projection 280e within the meaning of the present invention, which extends over the length of the inner channel.
[0064] In some embodiments of a fixed-point sleeve, the head 320 of the fastening element 300 can additionally be laterally fixed to further reduce the movement between the fastening element and the mounting element. In such a case, also shown in Figure 7(b), the area of the rear opening of the channel 220 of the sleeve-shaped body can have a recess 285c into which the head 320 of the fastening element 300 can penetrate and be positively engaged. In this way, the fastening element 300 is positively engaged at several points with the mounting element 200, which is shown in Figure 7(b), and relative displacement between the fastening element 300 and the mounting element 200 is prevented. In this case, the mounting element is therefore a fixed-point sleeve.
[0065] Figure 8 shows an assembly aid 200g according to the invention based on the principles of Figure 4 in the embodiments of (a) fixed-point sleeve 200g and (b) sliding-point sleeve 200g. As in the embodiments of Figure 7, projections 280g are provided through which the fastening element is guided and – in the case of the fixed-point sleeve – held in a form-fitting manner, or – in the case of the sliding-point sleeve – which can break off or be deformed under force due to thermally induced deformation of the components, in order to allow a relative displacement of the fastening element relative to the mounting element.
[0066] Furthermore, the person skilled in the art understands that the principles of positive locking from Figure 7 can also be used with a hinged sleeve as in Figure 8, and that the projections located inside the channel of the embodiment from Figure 8 can also be used with a two-piece design as in Figure 7.
[0067] Figure 9 shows illustrations of an assembly method for the mounting element 200 according to the invention on a substrate 400. In a first process step in Figure 9(a), the mounting element 200 with the inserted fastening element 300, which in this case is designed as a self-drilling / self-tapping screw, is guided to a substrate 400 and set in rotation to penetrate the substrate 400. For this purpose, a setting tool can penetrate through the opening in the holding area (see Figures 2(b), 3(b), 4(b)) and engage the drive of the fastening element 300 to set it in rotation. Figure 9(b) shows the state of a mounted mounting element 200 by fully screwing the fastening element 300 into the substrate until the collar of the mounting element, in particular its projections, rests against the surface of the substrate 400.
[0068] Figure 10 shows a representation of an assembly method for the relative arrangement of a component (here a support profile 500) with a keyhole bore 100 on a mounting element 200, which is anchored in a substrate 400. The mounting element 200 can, for example, be anchored in the substrate 400 according to the principles of Figure 9.
[0069] Figures 10(a) and (b) show how the support profile 500 is slid over the conical retaining area of the mounting element 200. For this to occur, the conical retaining area penetrates the area of the keyhole-shaped receptacle 100 with the larger diameter. The dashed arrow and the top view of the keyhole-shaped receptacle 100 indicate its orientation within the support profile 500, as this orientation would otherwise not be apparent in the cross-sectional drawing of Figure 10. The sliding onto the conical retaining area is indicated by the arrow in Figure 10(b). Once the retaining area is fully inserted into the keyhole-shaped receptacle 100, the support profile 500 can be moved relative to the mounting element 200, with the retaining area sliding into the area of the keyhole-shaped receptacle 100 with the smaller diameter.Since the illustrated embodiment of the mounting element 200 has a collar and a step behind the retaining area, Figure 10(c) shows how the boundary of the keyhole-shaped receptacle 100 of the support profile 500 sits in the recess 250 (cf. Figures 2(c), 3(c), 4(c)) between the collar and the retaining area. This secure fit is illustrated in two further views in Figures 11(a) and (b), where it becomes clear how the retaining area, which slid into the receptacle in the area of the keyhole-shaped receptacle, was displaced relative to it by a displacement of the support profile 500.
[0070] Although the methods described with reference to Figures 9 and 10 are based on the case where the mounting element 200 is anchored in the substrate 400 and a structural element in the form of a support profile 500 is attached to the holding area of the mounting element 200, those skilled in the art understand that the same principles also apply when the mounting element 200 is attached to a structural element and the keyhole-shaped receptacle 100 is located in the substrate 500 or another structural element to be attached to the structural element. In this context, reference should again be made to the orientation of the keyhole-shaped receptacle 100 mentioned in connection with Figure 1. If the mounting element 200 is attached to a structural element, the structural element can, for this purpose, have a receptacle for the fastening element 300 of the mounting element, for example, in the form of a section with an internal thread.In this case, the fastening element 300 does not need to be self-drilling / self-tapping.
[0071] The above description contains exemplary embodiments of one or more embodiments of the invention. Naturally, it is not possible to describe every conceivable combination of the components and methods according to the invention in the aforementioned exemplary embodiments. Rather, a person skilled in the art will recognize that there are numerous further combinations of other embodiments. Accordingly, the described exemplary embodiments are intended to encompass all such further combinations, modifications, variations, and embodiments that fall within the scope of the appended claims.
