    "CAGE NUT HAVING A RETENTION DEVICE" [0001] A cage nut comprising a retention device and a method for producing said cage nut are described. The cage nut comprises a nut that comprises an angled flange projecting radially, and a receptacle such as a threaded sleeve for a dowel. A support comprising a passage opening through which the pin receptacle passes as a glove, engages in a manner as a support on the angular flange of the nut. A retaining collar that surrounds the bolt receptacle as a nut sleeve is supported on the support in the region of the through opening.
    [0002] Such a cage nut is known from DE 94 09 087 U1 as a retention device for a nut. Cage nuts of this type are used as part of a connection of nut and bolt components, such as in motor vehicle engines or seats in a vehicle, which are connected by means of the cage nuts to a support of the vehicle body. To simplify the assembly, the cage nut is pre-assembled by means of the support in the region of the support passage opening, whose opening is indicated for threaded bolts. For this purpose, the support is rigidly connected to the support and, in the installation position, it engages over the nut that is loosely arranged within said support.
    [0003] During the subsequent screwing of a threaded bolt into the nut thread of the bolt receptacle as a threaded sleeve, the support provides fixed support in rotation for the radially projecting flange, which is provided on the nut. At the same time, the support prevents the nut from stretching in the axial direction of the threaded bolt. Consequently, the threaded bolt can be screwed into the nut without said nut having to be fixed manually or using corresponding tools.
    [0004] To compensate for mounting tolerances between a component to be mounted, such as an engine or a vehicle seat and the attachment points provided in the body that comprise a cage nut, the nut is retained in the support loosely. Consequently, a space remains between the outer radial periphery of the bolt receptacle as the threaded sleeve of the nut and the opening of
    2/14 passage in the support. As a result, when using the known support, there is a risk that the nut on the support may tip against the axial orientation of the threaded bolt. Due to the tilting movement of the nut, it becomes difficult to screw the threaded bolt into the inner thread of the nut in a coaxial direction.
    [0005] In addition, nuts on conventional supports cause a disturbing rattling noise when the cage nut is supplied to the component at a plurality of attachment points so that it is possible to use a plurality of component variants at any time. Excessive cage nuts, which are used in accordance with the assembly requirements of a plurality of different component variants, can move relatively freely in the support in this case and, as a result [0006] can cause these disturbing rattle noises, particularly within of a vehicle, especially since the nuts can move freely on known supports in an axial and radial direction and rotating from the angular flange region can lead to disturbing noises of metallic impact that give the impression that this model has been mounted in an unsafe and incorrect manner.
    [0007] The problem faced by the Order is that of providing a cage nut in which the risk of tipping is reduced, and noise is suppressed for cage nuts that have been mounted and fixed as a precautionary measure. One method is further specified using that such a cage nut can be produced.
    [0008] This problem is solved by independent claims. Advantageous developments emerge from the dependent claims.
    [0009] As a solution to this problem, a cage nut comprising a holding device and a method for producing said cage nut are described. The cage nut comprises a nut that comprises an angled flange projecting radially, and a receptacle such as a threaded sleeve for a dowel. A support comprising a passage opening through which the receptacle passes as a sleeve for a pin, engages in a manner as a support on the angular flange of the nut. A retaining collar that surrounds the receptacle as a glove for the nut bolt is supported on the support in the region of the through opening. The necklace of
    3/14 retention is in one piece and comprises first and second cover elements that cover the passage opening of the support on both sides. The retaining collar cover elements in one piece are mechanically connected by means of a connection sleeve that concentric joins the pin receptacle. The connection bushing is radially spaced apart from the through opening.
    [0010] An advantage of this cage nut that included a retention device is that when assembling the cage nut, the number of parts to be interconnected is reduced to three elements, specifically, a specially shaped cage nut, a support and a collar of retention, such that a cage nut of this type in its support and can be produced in a cost effective way. Another advantage is that, due to the fact that the retaining collar is in one piece, the displacement capacity of the nut is ensured while maintaining its axial orientation in the passage opening.
    [0011] In addition, the nut is fixed by the retaining collar in the axial direction, in such a way that tilting the centerline of the nut inside the support is no longer possible due to the retaining collar in one piece. Finally, the axial movement of the nut and the rotation of the angular flange are restricted to such an extent that touch or metallic contact that causes noise between the support and the nut is prevented by the retaining collar in one piece. Due to the retaining collar, the radial displacement that is allowed within limits does not lead to any mechanical contact between the metal nut and the metal support. Noise from unusual positions that have a cage nut is thus prevented.
    [0012] In another embodiment, the cage nut support comprises an insertion slot for the retaining collar to insert the retaining collar into the passage opening. Said insertion slot has an opening width which is, however, less than the outer diameter of the retaining collar connecting bushing in one piece. It is therefore provided that the connecting bush comprises, respectively, opposite slots in the transitions for the covering elements, such that a resilient portion is formed on both sides of the threaded bush, whose
    4/14 tion stretches into the insertion slot when the retaining collar is pushed, and jumps back to its original shape when it reaches the through opening. Due to this jump back, permanent loss protection is achieved as soon as the bolt receptacle as threaded sleeve is pushed into the retaining collar.
    [0013] It is also provided that, to fix the cage nut on the retaining collar, the bolt receptacle as a threaded sleeve protrudes beyond the retaining collar in one piece, and comprises caulking points distributed over the periphery of the projecting region.
    [0014] Said caulking points can be made in a compression press by means of a punch in a simple way, and are usually distributed over three points on the periphery of the projecting end of the peg receptacle. The depth of the caulking points can be adjusted on the compression press. By adjusting the size of the caulking point, the sliding displacement capacity of the retaining collar in one piece on the support in the region of the through opening can finally be adjusted, especially since, when caulking, the retaining ring in one piece is fixed between the radially projecting angular flange and the caulking points.
    [0015] In addition, it is provided that the first retaining collar cover element in one piece is arranged between the projecting angular flange and the support projecting beyond the angular flange edge faces. Due to this protrusion of the first cover element beyond the edge of the angular flange, it is also ensured that radial displacements of the nut, and thus of the angular flange in the support, cannot lead to a metallic contact that causes noise between the support and the nut. This provides protection against noise and ensures complete electrical insulation between the nut and the support.
    [0016] The complete isolation of the nut that has an internal thread, provides another advantage in which, for example, during subsequent coating operations in a dip cathodic coating bath, only the cage nut support, whose support is welded to the body , is coated. Since the nut itself
    5/14 cannot be exposed to the coating potential, the coating remains limited to the metal support. The nut itself, which is electrically insulated by means of the retaining collar on a piece made of plastic material, and in particular its internal thread, remains free of a coating layer in spite of the metallic conductive cage. In addition, it is provided that the second cover element that is supported on the support does not protrude beyond the support itself and is preferably disk-shaped. The outer dimensions of the cage nut are thus determined by the support.
    [0017] In another embodiment, the first cover element is a plate that is arranged between the projecting angular flange and the support, said plate comprising dentures formed in a wave resiliently pre-tensioned in the transverse edges to the insertion slot in relation to the Support. By pushing the retaining collar into the insertion slot, said resiliently pre-tensioned waveformed teeth ensure that the connecting sleeve is axially oriented and the nut can be positioned in a resiliently pre-tensioned axial orientation in the connection bushing, without problems.
    [0018] Additionally, it is provided that the second cover element that rests on the support comprises protrusions. Said protrusions are provided in such a way that the second covering element, when pushed into the insertion slot, can pre-tension the resilient wave-shaped indentations of the first covering element on the support. The second cover element can be correspondingly formed, and can or comprise pre-tensioned elastic elements if the first cover element comprises corresponding protrusions to compress the elastic elements of the second cover element against the support, or the second cover element it may comprise corresponding protrusions for pre-tensioning the pre-tensioned waveformed teeth mentioned above of the first cover element against the support in the region of the through opening. These modalities are presented in detail in the figures below.
    [0019] In addition to the radial cracks mentioned above in the transition regions
    6/14 between the cover element and the connection bushing to form elastic elements of the connection bushing and to form the wave-shaped indentations or protrusions of the cover elements, another measure is provided to improve the radially displaceable seat of the nut on the passage opening. For this purpose, other transverse slots are provided in the connecting element. Said transverse slits are provided so as to be parallel to the resilient wave-shaped indentations and transverse to the insertion slit in the transition from the connecting element to the first covering element. Said additional cracks in the connection bushing, which are positioned transverse to the insertion slot and parallel to the wave-shaped indentations or protrusions, weaken the connection bushing that mechanically connects the first and second cover elements of the retaining collar in a piece, but they are not cut or cut so deeply in order to unbalance the coherence of the retaining collar in a piece. These free cuts make it possible to arrange the resilient waveformed dentures closer to the connection bushing, and thus produce a larger region of action that has pre-tensioning.
    [0020] Another modality provides that the radially projecting angular flange is rectangular. In this case, the support comprises three angled legs of a base plate that comprises the passage opening, the three legs engaging on three edge faces of the nut's rectangular flange. By means of these three legs the cage nut can be safely welded to a position of fixation of the body region and, at the same time, the nut can be fixed on the support and in the fixation position in a way fixed in rotation, but radially displaceable through the rectangular flange.
    [0021] The capacity of displacement of the nut inside the support does not depend on the requirements of the tolerance bands in the manufacture, but it is provided that the nut that comprises the retaining collar that is pre-tensioned in the support has greater radial displacement in the direction of the crack insertion than in the direction transversal to the insertion slot. The cage nut can thus be prefabricated with a relatively high elongated slit length and elongated slit width
    7/14 low, such that the bolt receptacle as a threaded sleeve can be moved to the position of a threaded bolt.
    [0022] Although, as already mentioned above, the nut and the support comprise metal alloys, the retaining collar in one piece can be made of plastic material. Such a plastic material should be dimensionally stable and, nevertheless, have resilient properties to provide the various resilient elements for the cover plates of the cover elements.
    [0023] A method for producing a cage nut has the following method steps: Firstly a plurality of supports formed in support and comprising a base plate and three angled legs of a through opening comprising an insertion slot in the base plate, they are punctured from a sheet metal plate. This can take place in a single punching step, in such a way that mass production of supports conformed to this type of support is possible. Nuts are then produced, which comprise a radially projecting angular flange and have a bolt receptacle as a threaded sleeve for a bolt.
    [0024] After puncturing and then producing these two components for a cage nut, or at the same time, a retaining collar can be injection molded, the retaining collar comprising two cover elements that can cover the support opening opening on both sides and is provided with a connection bushing that connects the cover elements. Now that these three components are available for the cage nut, the retaining collar is first placed on the base plate of the support through the insertion slot, until the cover elements cover the edge regions of the through opening on both sides .
    [0025] The bolt receptacle as a threaded sleeve of the nut is then moved axially into the connection collar of the retaining collar in the passage opening. One end of the bolt receptacle as a threaded sleeve is then caulked, the end of which protrudes from the retaining collar to an axially oriented cage nut, which is mounted radially in the opening of
    8/14 pass. In this last step of the method, the contact pressure of the two cover elements over the edge region of the passage opening in the support can be additionally adjusted.
    [0026] This method has the advantage that cage nuts can be produced using relatively cost-effective manufacturing means and tools, and are fixed to the support in such a way that they are moreover sliding in the radial direction and remain axially oriented, however the nut cannot move in the axial direction so that the occurrence of noise or inclination is possible.
    [0027] A compression press that uses a caulking punch is provided for caulking, the entire projecting end of the bolt receptacle not being caulked in an annular manner, however, instead, caulking only takes place in three positions distributed over the periphery.
    [0028] A method for attaching components to a vehicle that uses a plurality of cage nuts according to the above modalities and that uses appropriate bolts, provides that vehicle seats are attached to profiled rails on the vehicle, or engines are attached to panels in a vehicle engine chamber, after which, legs of the cage nut supports are welded on the profiled rails or on the panels in predetermined fixing positions of supports. In this case it is possible, advantageously, to provide fastening points that are provided for other ranges of models, for example, in seat fastening, without the said cage nuts being fixed using blind threads or stops. The cage nuts are arranged so that they are attached to the support only by the retaining collar in one piece, in such a way that shocks cannot trigger any noise sources or loosen the nut of said retaining collar.
    [0029] Modalities are now described in greater detail with reference to the attached figures, in which:

    [0042] Figure 1 is a schematic perspective view of a nut 4 for a cage nut according to the first embodiment. Said nut 4 comprises an approximately angular flange and a collar 5, from which a pin receptacle 6 for a threaded pin protrudes. Said nut 4 comprises a continuous internal thread 31 which extends from the underside of the flange 32 to a projecting end 33 of the bolt receptacle 6. The projecting radially flange 5 is rectangular in this embodiment and has four edge faces 18, 19, 20 , 21. The length of the flange 5 between the edge face 18 and the edge face 20 is l1 and the width of the flange 5 between the edge face 19 and the edge face 21 is b1.
    [0043] Figure 2 is a schematic view in perspective of a support 7 for the
    10/14 cage nut according to the first modality. The support 7 comprises a base plate 30 in which a through opening 8 is provided, through which the bolt receptacle as threaded sleeve 6 of the nut 4 shown in figure 1 can be inserted in. The diameter d 3 of said passage opening 8 is considerably smaller than the diameter d1 shown in figure 1 of the pin receptacle. The base plate 30 is folded on three sides to form legs 27, 28 and 29, which can engage on the edge faces 19, 20 and 21, shown in figure 1, of the flange 5.
    [0044] An edge face 34 that does not comprise a leg of this type, has an insertion slot 13, of which the width b3 is smaller than the diameter d3 of the passage opening 8. In addition, the opposite legs 27 and 29 comprise foot elements 35, 36 and 37, by means of which the support 7 can be welded on a support of a vehicle body. The legs 27 and 29 then engage the edge faces 19 and 21 shown in figure 1 of the radially projecting flange 5.
    [0045] Figure 3 is a schematic perspective view of a retaining collar 9 for the cage nut according to the first embodiment. Said retaining collar 9 is in one piece, and is composed of three components, specifically, of a first cover element 10, which can cover the passage opening 8 shown in figure 2, from below, of a second protection element cover 11, which can cover the passage opening 8 shown in figure 2 from above, and a connection sleeve 12, arranged between them that mechanically interconnects the two cover elements 10 and 11.
    [0046] The inner diameter d 4 of the connection sleeve 12 is dimensioned in such a way that it corresponds to the outer diameter d1 of the pin receptacle 6 of the nut 4 in figure 1, additional inner strands 40 ensuring a press fit of the pin receptacle 6 when mounting the cage nut. The outer diameter d5 of the connection bushing 12 is smaller than the inner diameter d3 of the through opening 8 shown in figure 2. As a result, sufficient play between the retaining collar in one piece 9 and the support 7 inside the through opening 8 of the support 7 shown in figure 2 is secured. The outer diameter d5 of the connecting sleeve 12 of the retaining collar 9 is also smaller than the width b3 of the insertion slot 13 of the support 7
    11/14 shown in figure 2.
    [0047] When pushing the retaining collar 9 into the passage opening 8 of the support 7 in the direction of arrow A through the insertion slot 13 as shown in figure 2, the retaining collar 9 should remain caught in the opening slot insertion
    13. To prevent this, the connection bushing 12 comprises radial slits 14 and 15 at the transitions from the connection bushing 12 to the cover elements 10 and 11, in such a way that opposite elastic elements 16 emerge. When inserting the retaining collar 9 into the insertion slot 13 in the direction of arrow A, said elastic elements 16 of the connecting sleeve 12 elongate and make it possible to position the retaining collar 9 in the through opening 8. In this case, the spacing remains between the connection bushing 12 and the passage opening 8, since the outer diameter d 5 is smaller than the inner diameter ds. This spacing makes it possible for the retaining collar 9 to be moved radially in the through opening 8.
    [0048] Due to the two cover elements 10, 11, the retaining collar 9 ensures that radial sliding displacement on the base plate 30 of the support 7 is possible. To ensure pre-tensioning between the support 7 and the retaining collar 9, the first cover element 10 is formed as a plate that comprises a waveformed toothing 25 at each of its edges 22, 23, the toothing of which can elongate from resiliently, the second cover element 11 conversely comprises projections 24 which are supported on the base plate 30 of the support 7 such that after inserting the retaining collar 9 into the through opening 8 through the insertion slot 13 the collar The retaining bracket is fixed to the base plate 30 in a sliding way.
    [0049] The inner opening 39 of the retaining collar 9 always remains axially oriented during possible radial displacements. After sliding the support 7 and the retaining collar 9 together, the nut 4 comprising the pin receptacle 6 can be moved through the inner opening 39 in the direction of arrow B as shown in figure 1, such that the legs 27 and 29 of the support 7 engage the flange 5 and edge 5 of the nut 4 on the faces 4. Pushing on part 4, the elastic element 16 is automatically locked, and this makes removal impossible
    Destructive 12/14. An assembled cage nut of this type can then be attached to a support by means of the foot elements 35, 36 and 37 of the legs 27 and 29 and a threaded bolt can be inserted through the underside of the flange 32 into the nut 4 which is held stable way in the axial direction.
    [0050] Figure 4 is a schematic longitudinal section through the cage nut 1 according to the first modality. In this longitudinal section, the three components that have been described above with reference to figures 1 to 3 are connected in such a way that the retaining collar 9 is arranged in the through opening 8 of the support 7 and covers the through opening 8 with its cover 10 and 11. The connection bushing 12 that mechanically connects the cover elements 10 and 11 of the retaining collar 9, keeps the nut 4 in the support 7 in an axially oriented manner by means of a coaxial press fit. In addition, the nut 4 is fixed in the inner opening 39 of the connection bushing 12 by means of its pin receptacle as threaded sleeve 6.
    [0051] A projecting region 41 from the retaining collar 9 comprises caulking points 17 that are distributed over the periphery and prevent the pin receptacle 6 from sliding out of the retaining collar 9. Opposite this region 41 of the nut 4, protruding from the retaining collar 9, the underside 32 of the radially projecting angular flange 5 is arranged, from whose underside a threaded bolt can be screwed into the inner thread 31 of the nut
    4. Since the foot elements 37 and 38 of the leg 29 are materially connected to a support of a panel, the nut 4 is fixed against, rotating the support 7 by means of the rectangular flange 5.
    [0052] In addition, the first cover element 10 of the retaining collar 9 made of plastic material, is adapted to the rectangular flange 5 such that the length l2 shown in figure 3 is slightly longer than the length l1 shown in figure 1 of the rectangular flange 5 and, likewise, the width b2, shown in figure 3, of the first cover element 10 of the retaining collar 9 is greater than the width b1 of the rectangular flange 5 shown in figure 1, which ensures that the rectangular flange 5 in the assembly as shown in figure 4, does not cause a
    13/14 short-circuit despite the radial displacement capacity of the retaining collar 9 in the passage opening 8, and the nut 4 remains insulated in all positions of the support 7. No electrical contact with the body thus occurs that in cathode dip coating in a cathode dip coating bath, the nut and its internal thread are also not coated.
    [0053] Figures 5 to 8 show a cage nut 2 according to a second embodiment of cage nut 1 described in figures 1 to 4. Components in figure 5 to 8 that have the same function as those in figures 1 to 4 are indicated by identical reference signs and are no longer discussed. It is easy to see that nut 4 and support 7 in figures 5 and 6 do not differ from nut 4 shown in figure 1 and support 7 shown in figure 2 and therefore further discussion is unnecessary. A modified retaining collar 9 'is only shown in figure 7 and differs from the retaining collar in figure 3 in that the connecting bushing comprises another slot across the insertion slot 3 shown in figure 2 as a free cut 42 in addition to the slots radials 14 and 15.
    [0054] Said free cut 42 can be seen more clearly in figure 8 which is a schematic longitudinal section through the cage nut 2 according to the second modality. In this longitudinal section according to figure 8, the free cut 42 can be seen in the circle marked C, it being possible by means of this free cut 42 that the resilient wave shaped toothing 25 is arranged considerably closer to the passage opening 8, so that both the elastic constant of the resilient wave-shaped dentition 25 can be reduced and a compact construction of the cage nut 2 is possible, since the longitudinal extension of the projecting flange radially 5 can be reduced. Figures 9 to 12 show a third embodiment of a cage nut 3, in which components that have the same functions as in the preceding figures are also indicated by identical reference signs and are no longer discussed. In this third embodiment, nut 4 can also be seen in figure 9, and support 7, as can be seen in figure 10, remains unchanged as already described with reference to figures 1 and 2.
    14/14 [0055] Only the retaining collar 9 differs from the previous embodiment in that the lower cover element 10 has a flat surface from which protruding projections 24 protrude. Elastic elements 25 protrude from the opposite cover element 11 in the direction of the base plate 30 shown in figure 10, of the support 7, whose elastic elements ensure that the retaining collar 9 can be inserted in the support 7 under pre-tensioning. In this embodiment, also, by means of the size of the flat cover element 10, it is ensured that the radially projecting angular flange 5 cannot cause a short circuit between the support 7 and the nut 4, despite the radial displacement capacity of the collar. retention 9 on support 7. Noise is also prevented by this new retaining collar 9.
