Fastener holder, mounting system and method for mounting a fastener

Description

[0001] The invention relates to an assembly system and a method for assembling a fastening device.

[0002] Screws and other fasteners, such as bolts, are already known from the prior art. These serve to clamp a first component to a second component. For this purpose, the bolts are inserted into a hole in the first component and then screwed into a threaded nut, for example, in the second component. However, a problem arises because the bolt can easily fall out of the hole in the first component if it is not immediately screwed into the threaded nut. This can lead to bolts being lost, especially in complex manufacturing processes, because the assembly step of screwing them in usually does not take place immediately after insertion into the hole in the first component.

[0009] A state-of-the-art assembly system is shown in WO 2004 / 102016 A1.

[0010] The object of the invention is therefore to provide a way to allow simple assembly of fastening devices, which is also cost-effective.

[0011] This problem is solved by a mounting system according to claim 1 and by a method for mounting a fastening element according to claim 14. Further advantages, features and advantageous embodiments will become apparent from the dependent claims, the description and the figures.

[0012] According to the invention, a fastener holder is provided. The fastener holder serves to hold or position a fastener in a mounting hole without requiring the fastener to be screwed in. In other words, fastener holders according to the invention, for example, or advantageously, do not serve to transfer an operating load between the fastener and the component(s). Therefore, fastener holders advantageously serve only to temporarily support the fastener and / or to support the fastener against its own weight. In other words, the fastener holder is thus, particularly in one embodiment, a temporary fixing or holding device. The mounting hole of the fastener holder can, for example, be an elongated hole, a bore, or another recess or opening.Advantageously, the mounting hole has an internal thread in its inner wall and / or is preferably designed to be completely free of internal threads. The fastening holder according to the invention allows for the particularly simple pre-positioning of a fastening element in a mounting hole, whereby the fastening element held by the fastening element holder can be permanently screwed in at a later time. The fastening element holder has a base body. This base body is, in particular, one or the main component or, more specifically, the central component of the fastening element holder. The base body extends in the longitudinal direction. Advantageously, the longitudinal direction is the direction in which the base body has its largest main dimension and / or in which the length of the base body is determined and / or in which the receiving opening extends.The receiving opening completely penetrates the base body in the longitudinal direction. Advantageously, a radial direction extends perpendicular to the longitudinal direction, and a circumferential direction extends around the longitudinal direction. In other words, the longitudinal direction, the radial direction, and the circumferential direction can form a cylindrical coordinate system, where the longitudinal direction is the vertical coordinate, the radial direction is the radial coordinate, and the circumferential direction is the angular coordinate. As already explained, the fastener holder has a receiving opening that extends completely through the base body. The receiving opening serves—in a holding state—to receive the fastener and exert a holding force on the fastener to prevent it from falling out of the receiving opening. According to the invention, this holding force is generated by an interference fit.achieved by a press fit between the fastener and the receiving opening.

[0013] The receiving opening is essentially rotationally symmetrical about its longitudinal direction and therefore has an inner wall that is also essentially rotationally symmetrical about its longitudinal direction. "Essentially rotationally symmetrical" can be understood to mean, in particular, that the receiving opening is rotationally symmetrical about its longitudinal direction, except for minor manufacturing tolerances. Alternatively, or preferably, the receiving opening can also be completely rotationally symmetrical about its longitudinal direction. This essentially rotationally symmetrical design allows for a particularly cost-effective design of the receiving opening, which can nevertheless reliably exert a holding force on a fastener. The fastener holder has at least one mounting structure extending transversely to the longitudinal direction. This mounting structure extends radially away from the base body.The at least one mounting structure, preferably the plurality of mounting structures, serves to come into contact with the mounting hole (or a mounting hole) in a mounted state such that, particularly through the existing friction, they generate or provide a holding force in conjunction with the mounting hole. In other words, in a mounted state, the mounting structures form at least a friction-fit retaining connection with the mounting hole in order to prevent the fastener holder and the fastener from falling out, at least by friction, and in particular exclusively by friction, or by friction and form-fit. The mounting structures can be designed, in particular, as planar structures, for example as ears, flaps, or as radially circumferential flange elements or as a radially circumferential flange.A planar structure can be understood to mean, in particular, that the main direction of extension of the object, or its dimensions in this direction, are larger than in the longitudinal direction. Alternatively, a planar structure can also be understood to mean that the dimensions perpendicular to the direction of the material thickness are at least as large, preferably twice as large, and particularly preferably at least three times as large as the material thickness of the planar element or component. Alternatively or additionally preferably, the mounting structures can also be designed as, preferably separate, flange segments. The radially limiting end regions of the mounting structures, in particular the flange segments and / or the flange, are preferably designed to contact the mounting hole in which the fastener is to be held when assembled.The fastener holder according to the invention enables particularly simple assembly and provision of holding force for a fastener, and furthermore, the fastener holder results in a particularly cost-effective design due to the essentially rotationally symmetrical design of the receiving opening around the longitudinal direction or the inner wall of the receiving opening.

[0014] Advantageously, the inner wall surrounds the longitudinal direction. In other words, the inner wall can be designed such that it forms a completely closed contour in a cross-sectional plane perpendicular to the longitudinal direction, with the longitudinal direction located within this contour. Particularly or alternatively, the center point of the inner wall lies on the longitudinal direction. This results in particularly simple manufacturing and thus a cost reduction for the fastener holder.

[0015] Advantageously, the center of gravity of the base body and / or the mounting structures and / or the fastener holder lies along the longitudinal axis. By arranging the center of gravity of the base body and / or the mounting structures or the fastener holder along the longitudinal axis, a particularly balanced and easy-to-handle structure of the fastener holder can be achieved, thus facilitating both the casting process and the handling of the fastener holder.

[0016] Advantageously, the base body has an outer wall that is rotationally symmetrical about the longitudinal direction, in particular a cylindrical outer wall. This allows for a particularly simple-to-manufacture and mechanically robust base body structure. Advantageously, this rotationally symmetrical outer wall can only extend a portion of the base body outwards in the radial direction. Alternatively, or preferably, the base body can have an outer wall that is rotationally symmetrical about the longitudinal direction along its entire length, with this rotational symmetry being disrupted only by the mounting structure or the connection areas of the mounting structures. In other words, this can mean, for example, that the base body is completely rotationally symmetrical on the outside, except for the areas connected to the mounting structures.

[0017] Advantageously, the mounting structure or structures have a material thickness—particularly in the longitudinal direction—where the material thickness is less than the longitudinal length of the base body. In other words, the material thickness of the mounting structures, particularly of all mounting structures, or at least of one mounting structure, can be less than the longitudinal length of the base body. Advantageously, the material thickness is the thickness of the mounting structure, especially in the longitudinal direction. Alternatively, or additionally preferably, the material thickness can also be the dimension in which the mounting structure has its smallest main dimension.By providing a material thickness for the mounting structures that is less than the longitudinal length of the base body, a particularly cost-effective design of the fastener holder can be achieved. Furthermore, this allows for a high degree of flexibility in the mounting structure(s), enabling particularly easy insertion of the fastener holder into a mounting opening or hole. Preferably, the material thickness of the mounting structure(s) is in the range of 0.3 to 8 mm, more preferably in the range of 0.4 to 2 mm, and most preferably in the range of 0.7 to 1.2 mm.

[0018] In an advantageous embodiment, the ratio of the material thickness of the mounting structure to the diameter of the receiving opening is in the range of 0.05 to 0.3, preferably in the range of 0.07 to 0.25, and particularly preferably in the range of 0.09 to 0.2. The diameter of the receiving opening is, in particular, the nominal diameter of the receiving opening and / or the diameter of the smallest possible circle in a cross-sectional plane that can just surround the receiving opening, wherein the cross-sectional plane is, in particular, perpendicular to the longitudinal direction. With a ratio in the range of 0.05 to 0.3, a particularly good holding force and thus a particularly high degree of holding capacity for a fastener can be achieved by means of the fastener holder in a mounting hole.However, if the ratio is in the range of 0.07 to 0.25, the applicant has surprisingly discovered that this allows for particularly simple and cost-effective manufacturing. To achieve a particularly high degree of adaptability, especially with regard to angular compensation, of the fastening element, the ratio should be in the range of 0.09 to 0.2. The relevant material thickness is, in particular, the average material thickness of the mounting structure along its length; advantageously, the connection section of the mounting structure is not included in the determination of the material thickness.

[0019] It is particularly advantageous to design the material thickness to decrease continuously in the radial direction. This allows for a design that is particularly well-suited to the mechanical load. Alternatively, and preferably, the material thickness can also be constant in the radial direction. This allows for particularly simple and cost-effective manufacturing.

[0020] Advantageously, at least one mounting structure, preferably the majority of the mounting structures, and particularly preferably all mounting structures, extends substantially perpendicularly, preferably vertically, to the longitudinal direction. "Substantially perpendicular" means that the smaller angle between the enclosed directions must not be less than 60°, preferably 80°, particularly preferably 85°, and most preferably 88°. By providing mounting structures extending substantially perpendicularly to the longitudinal direction, both simple manufacturing and a high degree of holding force can be achieved. The direction of extension is understood to be, in particular, the direction or course of extension that points from the connection area of ​​the mounting structures to the distal ends of the mounting structures, which are, in particular, freely extending.In other words, the longitudinal dimension of the mounting structure can extend perpendicularly or at least substantially perpendicular to the longitudinal direction.

[0021] Advantageously, the mounting structures form the radial distal region of the fastener holder. The radial distal regions are those areas of the fastener holder that are furthest from the longitudinal direction in the radial direction. In other words, the distal end regions of the fastener holder are formed by the mounting structures in the radial direction. This ensures particularly good holding force and particularly easy installation of the fastener holder.

[0022] Advantageously, the mounting structure and / or structures have an outer surface bounded in a radial direction, the contour of which forms a projection radius in a projection plane, the projection plane being defined in particular by the longitudinal and radial directions. The rounded design of the radially bounding areas of the mounting structures allows for particularly good mounting and holding force development, as the outer surface that is to contact the mounting hole is already pre-adapted to the contour of the mounting hole. The center point of one, and in particular all, projection radii is expediently located on the longitudinal direction.

[0023] In a preferred embodiment, the ratio of the diameter of the receiving opening to the projection radius is in the range of 0.6 to 1.8, preferably in the range of 0.7 to 1.5, and particularly preferably in the range of 0.8 to 1.3. By using a ratio in the range of 0.6 to 1.8, a particularly good holding force can be generated. However, if the ratio is in the range of 0.7 to 1.5, a particularly simple-to-manufacture variant of the fastener holder can be achieved. If, however, the ratio is in the range of 0.4 to 1.3, the assembly of the fastener holder can be simplified, as the applicant has surprisingly discovered that this results in a particularly comfortable assembly force requirement for the user. In other words, a particularly easy-to-assemble device can be achieved.

[0024] Advantageously, the ratio of the outer wall diameter to the projection radius is in the range of 1.05 to 3.33, preferably in the range of 1.25 to 2.5, and particularly preferably in the range of 1.5 to 2.0. By designing the ratio in the range of 1.05 to 3.33, a particularly good holding force can be generated. However, if the ratio is in the range of 1.25 to 2.5, a particularly simple-to-manufacture variant of the fastener holder can be achieved. If the ratio is in the range of 1.5 to 2.0, the assembly of the fastener holder can be simplified, as the applicant has surprisingly discovered that this results in a particularly comfortable assembly force requirement for the user. In other words, a particularly easy-to-assemble device can be achieved.

[0025] Preferably, the mounting structure, preferably the majority of mounting structures, and particularly preferably all mounting structures, have a connection section, wherein the mounting structure is / are connected to the base body via the connection section, wherein the connection section may have a connection groove, in particular a connection fillet, wherein the connection fillet has a groove radius. The connection section can also be referred to as the connection region or connection section. By providing a connection section on the mounting structure, a particularly mechanically robust and compact design of the fastener holder can be achieved. By providing a connection fillet in the connection section, the mechanical strength, in particular the fatigue strength, of the fastener holder can also be increased.The throat radius of the connecting fillet of the connecting section is determined in particular in a plane that is spanned by the radial and longitudinal directions. Furthermore, by designing the connecting section as a fillet, the notch effect factor can also be reduced.

[0026] In a preferred embodiment, the ratio of the throat radius to the diameter of the receiving opening is in the range of 0.05 to 0.3, preferably in the range of 0.09 to 0.25, and particularly preferably in the range of 0.09 to 0.2. If the ratio of the throat radius to the diameter is in the range of 0.05 to 0.3, a particularly robust yet elastic connection of the mounting structure to the base body can be achieved, thus enabling particularly good holding force generation or provision of a holding force for a fastener in the fastener holder. To achieve a particularly low notch effect and thus a particularly high degree of fatigue strength, the ratio should be in the range of 0.09 to 0.25.However, if the ratio is in the range of 0.09 to 0.2, the applicant has surprisingly found that a particularly advantageous manufacturing method, especially by means of injection molding, can be achieved, resulting in a particularly cost-effective fastener holder.

[0027] Advantageously, the fastener holder has at least one, preferably a plurality of, through-openings, wherein at least one, preferably all, of the through-openings are formed in the mounting structure and / or between mounting structures. In other words, one or more through-openings can be provided that extend through a mounting structure or are formed between the mounting structures. The through-openings serve to allow moisture to pass through or around the mounting structures in order to prevent corrosion. The through-openings can be designed such that they completely penetrate the mounting structures, particularly in the longitudinal direction. Alternatively or additionally preferably, one or more of the through-openings can be designed such that they separate the mounting structures from one another.For example, through-holes can be incorporated into the radial end regions of the mounting structures in such a way that one mounting structure is effectively divided into two. In addition to the effect of moisture permeability, increased flexibility of the mounting structures can be achieved, particularly through radially positioned through-holes.

[0028] Advantageously, the through-holes, particularly at least three, are arranged equidistantly in a circumferential direction. "Equidistant in the circumferential direction" means that the angle between the through-holes is always the same. For example, with three through-holes, the angle between them can always be 120°. This equidistant arrangement of the through-holes allows for particularly good centering of the fastener being mounted by the fastener holder in the mounting hole.

[0029] InIn a preferred embodiment, the through-holes separate the mounting structures, or at least two mounting structures, from each other in the circumferential direction. "Separation" here means that the through-holes create independent mounting structures, in particular different radial distal regions of the mounting structures. In other words, at an extreme, the through-holes can be designed such that the mounting structures are mechanically completely independent of each other. In other words, the through-holes can be designed such that the mounting structures are no longer connected to each other in any way—except indirectly via the base body.By separating the mounting structures through the through-holes, the flexibility and elasticity of the mounting structures can be increased, making assembly easier while simultaneously providing a high holding force.

[0030] Advantageously, the mounting structure(s) and / or the base body are formed in one piece, with the entire fastener holder being advantageously formed in one piece. This one-piece design allows for a particularly robust mechanical structure. It is particularly advantageous if the entire fastener holder and / or the mounting structures are formed in one piece together with the base body. "One piece" in this context means, in particular, that the relevant components or elements were manufactured by a single primary forming process.

[0031] Advantageously, the mounting structure(s) and / or the base body are made of a polymer, particularly a rubber, preferably a synthetic rubber, and / or a metal. Using a polymer allows for a particularly cost-effective version of the fastener holder. However, if a rubber is used, the fastener holder, mounting structures, and / or base body can be adapted very flexibly to the respective complementary component, especially the mounting hole and / or the fastener. Using a synthetic rubber results in particularly simple and cost-effective manufacturing of the fastener holder or the respective component made of synthetic rubber.If, alternatively or additionally, at least one of the components is preferably made of metal, this can increase the mechanical strength of the fastener holder.

[0032] In an advantageous embodiment, the mounting structure(s) and / or the base body are made of EPDM and / or the synthetic rubber is EPDM. EPDM, which can also be described as ethylene propylene diene monomer rubber, offers a high degree of UV resistance, thus increasing the shelf life of the fastener holder. Furthermore, this ensures that the flexibility of the fastener holder and / or the EPDM element is maintained even in cold temperatures. This can be particularly important for providing sufficient holding force for the fastener during winter.

[0033] Advantageously, the fastener holder has at least two, preferably at least three, and particularly preferably a plurality of mounting structure rows in the longitudinal direction. This allows for a particularly high holding force to be provided. The term "mounting structure row" is understood to mean, in particular, that a series of mounting structures is formed when there is a plane perpendicular to the longitudinal direction in which several independent and / or interconnected mounting structures are present. Advantageously, several mounting structure rows are present, spaced apart from each other in the longitudinal direction. For example, such a mounting structure row can be formed by providing three radially outwardly extending mounting structures, particularly in the form of flaps, in a plane.Advantageously, a second row of mounting structures, designed in the same or a similar manner, can be provided longitudinally spaced from the first row of mounting structures to increase the available holding force. Alternatively, or preferably, the resulting advantages can also be achieved by arranging several fastener holders in a longitudinal row on the fastener in the assembled state. The advantage of two or more fastener holders compared to just one fastener holder with two or more rows of mounting structures is that they can be easily demolded, resulting in more cost-effective and simpler manufacturing.

[0034] The fastener has an external thread, wherein the external thread has a diameter, and wherein the external thread is preferably a metric or an imperial thread, and / or wherein the ratio of the diameter of the receiving opening to the thread diameter can advantageously be in the range of 0.7 to 0.95, preferably in the range of 0.75 to 0.92, and particularly preferably in the range of 0.8 to 0.9. In other words, the fastener can have an external thread, wherein this external thread has a nominal diameter. To achieve particularly versatile and cost-effective application of the mounting system, the external thread should be a metric or an imperial thread.If the ratio of the diameter of the receiving opening to the thread diameter of the external thread is in the range of 0.7–0.95, this allows for particularly easy installation of the fastener in the fastener holder. However, if the ratio is in the range of 0.75–0.92, this allows for a particularly high holding force between the fastener holder and the fastener.

[0035] In an advantageous embodiment, the mounting system comprises two, preferably three or a plurality, fastener holders as described above and below. This allows the holding force provided by the mounting system for the fastener to be further increased effectively and easily. Advantageously, the fastener holders can be arranged such that they are in contact with each other when mounted. This increases the compactness of the mounting system.

[0036] Another aspect of the invention relates to a method for assembling a fastening device with the features of claim 14.

[0037] Such a method allows for the achievement of the advantages described above and below. Advantageously, such a method for mounting a fastener can include the further step of inserting the fastener holder into a mounting opening or hole, particularly in a component to be clamped. The method can also incorporate the features of the devices described above and below in at least an equivalent manner.

[0038] Further advantages and features of the present invention will become apparent from the following description with reference to the figures. Individual features of the illustrated embodiments can also be used in other embodiments, unless this has been expressly excluded. The figures show: Figure 1 is an isometric view of a fastener holder; Figure 2 a longitudinal view of a fastener holder; Figure 3 a side view or sectional view of a fastener holder; Figure 4 a side view or sectional view of another fastener holder; and Figure 5 a mounting system.

[0039] In the Figure 1 A fastener holder 1 is shown. The fastener holder 1 comprises a base body 10 and three mounting structures 50, which extend transversely to the longitudinal direction L. The base body 10 has a cylindrical outer wall 16 and a receiving opening 12, which has an inner wall 14 symmetrically formed about the longitudinal direction L. The mounting structures 50 are separated from each other in the circumferential direction U by the through-openings 60. Each of the mounting structures 50 has an outer surface 52 bounded in a radial direction R.

[0040] In the Figure 2 A view of a fastener holder 1 is shown, with the viewing direction in the Figure 2 is directed opposite to the longitudinal direction L. Extending radially away from the longitudinal direction L is the radial direction R. The circumferential direction U is formed around the longitudinal direction L. In principle, the Figure 2 illustrated embodiment to the Figure 1 and / or to the one in the Figure 3 The embodiment shown is suitable. The three mounting structures 50 of the fastener holder 1 extend in the radial direction R and are each connected to the base body 10 via a connection section 54. The mounting structures 50 have an outer surface 52 bounded in the radial direction R, the contour of which is defined in the Figure 2The projection plane shown forms a projection radius R1. The outer surface 52 forms a part of the radial distal areas 53 of the mounting structures 50. Between the mounting structures 50 is a through-hole 60, which is radially introduced from the outside and extends in the longitudinal direction L. The receiving opening 12 is located centrally in the base body 10, with the center point of the receiving opening 12 lying on the longitudinal direction L.

[0041] In the Figure 3 A side view of a fastener holder 1 is shown. In the Figure 3 The outer diameter D16 of the outer wall 16 of the base body 10 is visible. As the Figure 3 As can be seen, the longitudinal direction L is perpendicular to the radial direction R. The in the Figure 3The mounting structures 50 shown have a material thickness d, and the connection section 54, designed as a connection groove, has a groove radius R2. The fastener holder 1 has a length L1 of the base body 10 in the longitudinal direction L.

[0042] In the Figure 4 An alternative embodiment of a fastener holder 1 is shown, wherein the [missing information] Figure 4 The embodiment shown differs primarily in that it is described in Figure 3 The illustrated embodiment differs in that in the Figure 4 Several assembly structure series 51 are available.

[0043] In the Figure 5A mounting system 100 according to the invention is shown, comprising a fastening element 110 and two fastening element holders 1. In the illustrated embodiment, the fastening element 110 is a screw, in particular a high-strength screw. The fastening element 110 has an external thread 112 with a thread diameter D112. The two fastening element holders 1 are mounted on the external thread 112 of the fastening element 110. The axial cover surfaces of the respective base bodies 10 of the fastening element holders 1 contact each other, so that the fastening element holders 1 are arranged directly adjacent to each other on the external thread 112 of the fastening element 110.
