DETAILED DESCRIPTION

[0071] FIG. 1 shows an embodiment of a connection of a structural component S, which may be a vehicle body, with a component or add-on part A, which may be a vehicle light. The structural component S and the add-on part A are connected with each other by means of an adjustment element 1, an embodiment of which can be seen in a sectional view in FIG. 1.

[0072] The structural component S comprises a fastening opening B with an inner thread. According to a further embodiment, the fastening opening B may be provided by means of a blind rivet nut C with inner thread or by means of a welding nut (not shown) or by means of a thread opening directly in the structural component S.

[0073] FIG. 1 shows the blind rivet nut C in a not yet crimped state in the fastening opening B. FIG. 13 shows an embodiment in which the blind rivet nut C may have already been fastened in the fastening opening B of the structural component S.

[0074] The structural component may be provided with a threadless opening. The adjustment element 1 can be fastened to this opening with a blind rivet, a plug connection, a bayonet connection, a locking pin or the like.

[0075] In the following, a thread bolt 90 as an exemplary fastening means is described.

[0076] The adjustment element 1 according to FIG. 1 may consist of a sleeve like hollow screw 10. The sleeve like hollow screw 10 is formed similar to a hollow cylinder with a circumferential wall 12. The circumferential wall 12 comprises an outer thread 14 on its radial outside. The hollow screw 10 and thus the adjustment element 1 may be screwed together with the add-on part A via the outer thread 14.

[0077] The outer thread 14 may have a self-inhibiting configuration. The hollow screw 10 can thus be rotated in an opening of the add-on part A without the thread connection between the hollow screw 10 and the add-on part A releasing.

[0078] The thread connection between the hollow screw 10 and the add-on part A has the advantage that a rotating of the hollow screw 10 about its longitudinal axis L displaces the add-on part A relative with respect to the hollow screw 10 in the direction of the longitudinal axis L of the hollow screw 10. In this way, a distance Z between the add-on part A and the structural component S may be changeable and settable, as is shown in FIG. 1.

[0079] For this purpose, the hollow screw 10 is fastened to the structural component S, may be rotatable around its longitudinal axis L. The fastening is explained in more detail further below.

[0080] The bolt 90 may be rotatably screwed together with the structural component S by means of a central thread bolt 90. The thread bolt 90 is arranged in a tubular fastening opening 16 of the hollow screw 10. An inner diameter of the fastening opening 16 is larger than an outer diameter of the shaft 92 of the thread bolt 90. Based on this geometric configuration, the hollow screw 10 may be displaceable radially relative to the shaft 92 of the thread bolt 90, before the thread bolt 90 is firmly screwed together with the structural component S (see below). If the structural part S, to which the hollow screw 10 is fastened, is considered as an x-y-fastening plane with the fastening opening B arranged in there, the hollow screw 10 is displaceable in x-y-direction on the plane of the structural component S for the purpose of tolerance compensation before the thread bolt 90 is tightened (see FIG. 1).

[0081] Thus, beside the connecting of the add-on part A with the structural component S, the adjustment element 1 realizes a tolerance compensation in all three spatial directions x, y, z between the structural component S and the add-on part A. The adjustment possibility may guarantee in, for example, the vehicle construction the setting of desired gap sizes between a vehicle body and a vehicle lamp.

[0082] A similar embodiment of the hollow screw 10 is shown in FIG. 2. The hollow screw 10 extends along the longitudinal axis L with the thread 14 on the radial outer wall. The circumferential wall 12 may not comprise any thread on a radial inside 18.

[0083] Furthermore, the hollow screw comprises a fastening collar 20 projecting radially to the inside at a first axial end. The fastening collar 20 may extend inside of the hollow screw 10 in an enclosed manner, thus defining a tubular fastening opening 16.

[0084] The fastening collar 20 may have an inner radially extending rim 22 and an outer radially extending rim 24.

[0085] In the installed state of the adjustment element 1, the outer rim 24 rests against the structural component S directly or adjacent to it, which may be on the retention collar of a blind rivet nut C. An axial support sleeve 40 is arranged within the tubular fastening opening 16.

[0086] The support sleeve 40 may be configured longer than an axial distance between the inner rim 22 and the outer rim 24 of the fastening collar 20. If the hollow screw 10 is fastened to the structural component S, the outer rim 24 and the adjacent axial end 44, i.e. the end 44 of the support sleeve 40 which axially faces to the outside, rest against the structural component S. Accordingly, the outer rim 24 and the end 44 are aligned in a flush manner to one another. Due to the axial length of the support sleeve 40 in comparison with a length of the tubular fastening opening 16, expressed by the axial distance of the rims 22, 24, the end 42 of the support sleeve 40 which faces to the inside projects beyond the inner rim 22.

[0087] The axially inner end 42 of the support sleeve 40 may form a ring like abutment for a support disc 50. The support disc 50 is supported on the axially inner end 42 of the support sleeve 40. For this purpose, an outer diameter of the support disc 50 may be larger than an outer diameter of the support sleeve 40, thus guaranteeing that the support disc 50 is completely supported on the support sleeve 40 so as to transfer the mechanical fastening tensions from the underside of the head of the thread bolt 90 via the support sleeve 40 into the structural component S.

[0088] The support sleeve 40 may comprise a central opening 52. The shaft 92 of the thread bolt 90 passes through the central opening 52 in order to fasten the hollow screw 10 in the fastening opening B of the structural component S.

[0089] The difference in length between the tubular fastening opening 16 and the support sleeve 40 may guarantee a distance between the inner rim 22 of the fastening collar 20 and a side of the support disc 50 which faces the inner rim 22 in the fastened state of the hollow screw 10. This distance guarantees that even when in the fastened state, i.e. when screwed together with the structural component S, the hollow screw 10 is rotatable around its longitudinal axis L.

[0090] By that, which may be in the fastened state of the hollow screw 10, the distance Z between the add-on part A and the structural component S can be changed by rotating the hollow screw 10.

[0091] FIG. 4 shows the hollow screw 10 in combination with the support sleeve 40 after the production, which may be with a 2K injection molding method. Thus, the hollow screw 10 and the support sleeve 40 may consist of different plastic materials, which may be processed in the same manufacturing method. As a result, the hollow screw 10 and the support sleeve 40 shown here are available being connected by means of a predetermined breaking point 46 after the production method within the injection mold.

[0092] A 1K injection molding method may be used for the production of the hollow screw 10 and the support sleeve 40. The production routes which are described in the following may be applicable for both a 1K injection molding method as well as a 2K injection molding method.

[0093] According to a first manufacturing alternative, the hollow screw 10 and the support sleeve 40 according to FIG. 4 may be present after concluding the 2K injection molding method. After demolding, the two parts are separated and the support sleeve 40 is inserted into the tubular fastening opening 16 of the hollow screw 10 so as to achieve the arrangement according to FIG. 5.

[0094] According to a further manufacturing alternative, the predetermined breaking point 46 may be automatically separated during demolding the arrangement according to FIG. 4 and the support sleeve 40 is pressed into the fastening opening 16. For this purpose, the injection molding tool is adapted in order to release the predetermined breaking point 46 and to connect the hollow screw 10 and the support sleeve 40 with one another. Again, the result may be the arrangement according to FIG. 5 with the advantage that after the demolding, no further work step is necessary. Rather, the combination of hollow screw 10 and support sleeve falls out of the injection molding tool and is processible.

[0095] The support sleeve 40 within the tubular fastening opening 16 realizes a play between the support sleeve 50 and the fastening collar 20 via its length. A clamping of the hollow screw 10 due to the connection between the thread bolt 90 and the structural component S is thereby avoided.

[0096] The support sleeve 40 is retained in the fastening opening 16 which may be in a friction fit manner. Therefore, a friction between the support sleeve 40 and an inner wall of the fastening opening 16 determines a rotation resistance of the hollow screw 10 against the rotating of the hollow screw 10 around the longitudinal axis L. This rotation resistance may guarantee a set angle position of the hollow screw 10 around the longitudinal axis L. Furthermore, the rotation resistance has a stabilizing effect in terms of possible vibrations of the adjustment element 1 which could lead to a rotating of the hollow screw 10.

[0097] The friction fit between the inside of the fastening opening 16 and the radial outside of the support sleeve 40 may depend on the shape of the support sleeve 40. According to a configuration, the support sleeve 40 may be configured hollow-cylindrically (see FIG. 6a). For increasing the rotation resistance, radially projecting axial ribs 28, a knurling, projecting knobs and/or teeth are provided on the radial outside 48 of the support sleeve 40 and/or on the radial inside 26.

[0098] According to a further configuration of the support sleeve 40, the same may include a circumferential end collar 46 (see FIG. 6b). The end collar 46 provides and additional attachment surface at the hollow screw 10 which increases the rotation resistance and provides an axial limitation in the direction of the fastening opening 16. In addition, the same features may be provided on the radial outside of the support sleeve 40 as in the support sleeve 40 according to FIG. 6a.

[0099] As a further embodiment, FIG. 6 shows a support sleeve 40 having the shape of a truncated cone. The truncated cone-like support sleeve 40 has an outer diameter Dn. The outer diameter Dn may be larger than the inner diameter of the fastening opening 16. The radial outside may be provided with the same constructive features as the support sleeve 40 according to FIG. 6a.

[0100] On a face side of the support sleeve 40 facing the support disc 50 (not shown), FIG. 7 may show partial recesses, ribbings, teeth or any selection or combination thereof. They may serve for increasing the friction value between the fastening means 90 and the support sleeve 40 transmitted by the support disc 50.

[0101] According to a further configuration, the hollow screw 10 comprises a drive feature 60 at the first axial end 6 adjacent to the fastening collar 20 on the radial outside. The drive feature 60 may be a polygon, which may be a hexagon. It is arranged directly on the outside of the hollow screw 10.

[0102] According to a further constructive alternative, an axial projection 62 may be provided at the first axial end 6. It may have a smaller diameter than the hollow screw 10 in the portion of the outer thread 14. In this way, the drive feature 62 includes a radial free space which facilitates the engagement of a positive matching tool.

[0103] According to a further embodiment, the hollow screw 10 may have a radially inboard drive feature 64 at the second axial end 8. The inboard drive feature 64 may be adapted to form a form fit rotation connection with a tool 80. For this purpose, the radial inside of the circumferential wall 12 has a plurality of axially extending radially outwardly recessed grooves 66. The grooves 66 may be evenly distributed on the inner circumference of the hollow screw 10. The form-fit adapted tool 80 comprises evenly distributed axial webs 82 which engage into the grooves 66 (see FIGS. 8, 9, 12, 14).

[0104] The grooves extend in axial direction starting at the second axial end 8. The end of the grooves 66 facing away from the second axial end 8 each form a radial recess in order to hold the engaging axial web 82 of the tool 80. At a certain axial depth of the grooves 66, which may be ramp slopes 68 connect adjacent grooves 66. The ramp slopes 68 reduce the radial height of the radial limiting walls of the radial recess 66. As soon as an engaging axial web 82 reaches the ramp slope 68 and leaves the lower groove 66 because the tool 80 is removed from the second axial end 8, the form fit connection between the tool 80 and the hollow screw 10 is released.

[0105] When the tool 80 is for example rotated clockwise, the hollow screw 10 is screwed into the add-on part A. Meanwhile, the add-on part A moves in the direction of the second axial end 8 and encounters the tool 80 in form of the skirt 84. The skirt 84 encompasses the axial webs 82 at a radial distance. Furthermore, the skirt 84 extends in axial direction so that it partly covers the axial webs 82.

[0106] When the hollow screw 10 is screwed into the add-on part A, the tool 80 is moved through the add-on part A by means of the skirt 84 in the direction of the second axial end 8. Due to this movement in axial direction of the hollow screw 10, the axial webs 82 are displaced from the engagement in the grooves 66 into the portion of the ramp slopes 68, causing the form fit between tool 80 and hollow screw 10 to be released. In this way, it is avoided that the hollow screw 10 can be screwed out of the engagement with the add-on part A.

[0107] A further embodiment of an inboard form fit drive feature is shown in FIG. 10. A polygonal profile 70 is provided on the radial inside of the wall 12. A complementary formed tool can engage into this profile so that a torque between tool and hollow screw 10 can be transmitted. The tool may be configured similarly as the tool 80 with skirt 84. Instead of the axial webs 82, a polygonal structure is formed which engages the polygonal profile 70 in a form fit manner.

[0108] FIG. 11 shows an embodiment of an adjustment element 1 which may be fastened to a structural component S by means of a blind rivet nut C. The blind rivet nut C has been set into a fastening opening B of the structural component S. The adjustment element 1 is screwed together with the blind rivet nut C by means of a thread bolt 90 (not shown). The add-on part A is screwed onto the outer thread 14 of the hollow screw 10 and fastened there. The structural component S may be a part of the body of a vehicle and the add-on part A is a light.

[0109] FIGS. 12 and 13 illustrate a simplified installation of the add-on part A to the structural component S. For preparing the installation method, the adjustment element 1 may be screwed into an opening of the add-on part A, which may be_a lamp. That means that the add-on part A and the adjustment element 1 are available to the worker as a prepared component who only needs to fasten same to the structural component S and adjust the add-on part A in terms of its position.

[0110] In order to facilitate the fastening of the add-on part A to the structural component S for the worker, a fastening opening B in the shape of a thread opening is provided in the structural component S. According to a first embodiment, the fastening opening B may have an inner thread at its radial inner wall. The add-on part A with adjustment element 1 and a thread bolt 90 arranged in there in a loss-proof manner having a support disc 50 may be provided for the worker. The worker then screws the thread bolt 90 into the fastening opening B and fastens the add-on part A. After that, the distance between the add-on part A and the structural component S is changed with the help of the tool 80 according to a desired clearance.

[0111] According to a further embodiment, a blind rivet nut C may be fastened in the fastening opening B. Same provides a fastening thread for the thread bolt 90. The installation method proceeds accordingly as described above, with the exception that the thread bolt 90 is screwed into the inner thread of the set blind rivet nut C (see FIG. 13).

[0112] At the add-on part A, the preinstalled adjustment element 1 already comprises a blind rivet nut C arranged on the thread bolt 90. Therefore, the worker may arrange the add-on part A in a fitting manner in the structural component S, with the shaft 92 of the thread bolt 90 with preinstalled blind rivet nut C being inserted into the fastening opening B of the structural component S. As soon as the blind rivet nut C has been arranged in a fitting manner, the worker starts rotating the thread bolt 90 with the help of a suitable tool. The blind rivet nut C is set into the fastening opening B of the structural component by means of the rotation of the thread bolt 90 and the adjustment element 1 is fastened. After that, the worker adjusts the distance between the structural component S and the add-on part A (see FIG. 13).

[0113] In FIGS. 16-18, steps of an installation method of the add-on part A are shown at a structural component S with the help of an adjustment element 1. In addition to that, FIGS. 19 and 20 show steps for changing a distance between the structural component S and the add-on part A according to a desired clearance or other arrangement concepts.

[0114] Firstly, the structural component S with a fastening opening B and a blind rivet nut C fastened in there is provided (step S1, FIG. 16).

[0115] As a further preparation of the installation of the add-on part A, the hollow screw 10 or the complete adjustment element 1 may be screwed into an opening of the add-on part A (step S2a, FIG. 16).

[0116] According to a further configuration, the add-on part A with adjustment element 1 already fastened to it may be delivered or provided (step S2b). Therefore, the worker does not have to screw the adjustment element 1, which may be the hollow screw 10, in an opening of the add-on part A.

[0117] The thread bolt 90 is or will be arranged jointly with the support disc 50 within the axial support sleeve 40 (step S3). Due to the arrangement of the support sleeve 40 between the support disc 50 and the structural component S, the hollow screw 10 is rotatably held at the structural component S even after the thread bolt 90 has been tightened (FIGS. 17, 18).

[0118] After having arranged the thread bolt 90 in the adjustment element 1 and in the fastening opening B of the structural component S, the thread bolt 90 is screwed together with the thread of the fastening opening B and fastened with it (step S4a).

[0119] Before or during screwing tight the thread bolt 90 in the fastening opening B, the adjustment element 1 is moved in the plane of the structural component in order to compensate tolerances (see above and FIG. 1).

[0120] The lateral tolerance compensation may be enabled as a result of the inner diameter of the support sleeve 40 being larger than the outer diameter of the shaft 92 of the thread bolt 90 which passes through the support sleeve 40 (step S4b).

[0121] Once the add-on part A has been fastened to the structural component S by means of the adjustment element 1, the hollow screw 10 is rotated with the form-fit/positively acting tool 80. With the help of the rotation of the hollow screw 10, the distance between the structural component S and the add-on part A changes (step S5).

[0122] The positively acting tool 80 may engage into the second axial end 8 of the hollow screw 10. A structure is provided there, which may be at the radial inner side of the wall 12, which guarantees a form-fit and releasable rotation connection with the tool 80 (see FIGS. 19, 21 and 10).

[0123] The hollow screw 10 may be rotated with a tool by means of the radially outer drive feature 60 so as to set the distance suitably (step S6).

[0124] As can be seen from the sectional view in FIG. 21, the skirt 84 of the tool 80 guarantees that the hollow screw 10 is not screwed out from the add-on part A (see above).

[0125] For the sake of completeness and with reference to FIGS. 23 to 26, different alternative embodiments of the fastening means are shown which may be used instead of the thread bolt 90. FIG. 23 shows the use of a latching bolt 94 having a locking web 96 in connection with an additional spring element 98, e.g. in the shape of a circumferential spiral spring or an elastomer ring as fastening means. The associated FIG. 24 illustrates the necessary fastening opening B in the structural component S.

[0126] FIGS. 25 and 26 in turn show the use of a blind rivet nut 100 as fastening means. In FIG. 25, the adjustment element 1 is present in a non-fastened arrangement in the fastening opening B of the structural part S, complementary to that, a schematic single illustration of the used blind rivet 100 is shown on the left side in FIG. 25. In contrast to that, FIG. 26 illustrates the adjustment element 1 in a fastened arrangement. It can therefore be seen here that a compressed bead 102 has been formed.

[0127] These different fastening means may all fulfil the same function as the thread bolt 90 as fastening means. The adjustment element 1 may be fastened to the structural component S by means of these fastening means, wherein a rotation of the hollow screw 10 can be realized even after fastening the hollow screw 10 to the structural component S.
