[0002] From the German patent application DE 10 2008 012 133 A1, a car jack console for fastening to a motor vehicle body is known, comprising a base body which comprises a receiving area for a car jack and a fastening area which can be inserted into a body-side opening and which can be fixed in the body-side opening by a fastening element, for example a clamping screw, wherein the fastening area of ​​the base body is assigned a separate holding element which can be adjusted relative to the fastening area by means of the fastening element.From the German utility model DE 20 2006 019 863 U1, a car jack holder for fastening to a body of a motor vehicle is known, comprising a base body comprising a receiving area for a car jack, which comprises a fastening area engaging in a body-side opening, which is to be fixed to the body by means of an expansion pin, wherein in the area of ​​a support surface of the base body facing the motor vehicle body, a sealing arrangement is provided, which is formed by a sealing plate which is to be arranged between the support surface of the base body and the motor vehicle body.European patent application EP 2 020 352 A2 discloses a car jack console for fastening to a vehicle floor, with a support surface facing the vehicle floor and a console body having said support surface, from which an extension projects for engagement in a wall hole in the vehicle floor, said extension having an inner centering body formed as one piece on the console body and an outer latch body connected to said centering body and latchable on the wall hole, wherein the centering body is enclosed in the outer latch body in such a way that the two form a multi-part extension serving to firmly lock the console to the wall hole, wherein the latch body has two latch legs projecting from its central head part on both sides, which, when the extension is pushed into the wall hole, are pressed resiliently inwards by sliding contact of their outer inclined surfaces with the edge of the hole and then snap outwards, overlapping the edge of the hole.German patent DE 10 2006 030 769 B3 discloses a device for supporting a motor vehicle jack, comprising a base body made of hard plastic, which has spaced-apart, resilient mounting fingers projecting from one side of the base body. German utility model DE 20 2006 005 417 U1 discloses a jack support with a base body made of impact-resistant, hard plastic, from which base bodies protrude at a distance on a side facing the vehicle, with integral mounting fingers projecting from the base body, wherein a spreader pin can be inserted between the mounting fingers.

[0003] The object of the invention is to simplify the fastening of a car jack to a supporting structure of a motor vehicle by means of a holding element.

[0004] This object is achieved by a car jack receptacle having the features of patent claim 1. The captive attachment of the holding element to the car jack receptacle significantly simplifies installation of the car jack receptacle on the motor vehicle. In one of the positions, the holding element can advantageously be mounted on the support structure in a simple manner, for example, by being inserted into an opening in the support structure. The support structure is preferably part of a bodyshell of the motor vehicle, also referred to as the body. In another position, the car jack receptacle can particularly advantageously be pre-assembled on the support structure of the motor vehicle with the aid of the holding element. The holding element is preferably integrated into the car jack receptacle in such a way that the holding element can be moved in a defined manner relative to the car jack receptacle between the at least two positions.This further simplifies the handling of the jack support with the holding element during assembly. The defined movement between the open and closed positions can be achieved, for example, by at least one guide rail. However, the defined movement can also advantageously be achieved by at least one hinge or a hinge-like mechanism. This defined movement advantageously prevents errors during assembly. The fact that the holding element is pivotally attached to the jack support between the open and closed positions enables quick and easy assembly of the jack support with the holding element to the vehicle's supporting structure.

[0005] A preferred embodiment of the jack receptacle is characterized in that the holding element is clamped or latched to the jack receptacle in the closed position in order to secure the jack receptacle with the holding element to the support structure. This advantageously enables pre-assembly of the jack receptacle with the holding element to the support structure of the motor vehicle. Particularly advantageously, no additional tools, in particular no tools at all, are required for pre-assembly. The holding element in the open position can, for example, simply be pushed into an existing opening in the support structure. The pre-assembly can then be completed by a defined pivoting movement of the jack receptacle relative to the holding element fixed to the support structure.After pre-assembly, the jack support can be secured relative to the support structure and the retaining element, for example, using at least one suitable fastener. Clamping or locking is preferably performed in at least two places. This allows for a quick and easy, stable pre-assembly of the jack support with the retaining element.

[0006] A further preferred embodiment of the jack receptacle is characterized in that, in the closed position, the retaining element comprises at least one internal clamping point on the jack receptacle facing the support structure. The retaining element is secured in a defined direction at the internal clamping point during pre-assembly.

[0007] A further preferred embodiment of the jack receptacle is characterized in that, in the closed position, the retaining element comprises at least one external clamping point on the jack receptacle facing away from the support structure. When the jack receptacle is pivoted relative to the retaining element, the jack receptacle is positioned in a defined manner with the retaining element on the support structure.

[0008] A further preferred embodiment of the jack receptacle is characterized in that the holding element comprises at least one through-hole for a fastening body, preferably two through-holes for two fastening bodies, which protrude from the jack receptacle. With the at least one fastening body, the jack receptacle can preferably be positioned in a direction transverse to a connection between the inner clamping point and the outer clamping point. This ensures in a simple manner that the jack receptacle with the holding element is securely positioned in all three spatial directions during pre-assembly. The at least one fastening body serves to receive a fastening means with a screw. The jack receptacle, secured by clamping or locking with the holding element, is finally fastened to the supporting structure with the fastening means or the screw.Depending on the design, the jack holder with the holding element can also be easily dismantled again, but preferably only after removing the fastening device or the screw.

[0009] A further preferred embodiment of the jack receptacle is characterized in that the jack receptacle comprises a support body for support against the supporting structure. The support body allows the jack receptacle to be easily and stably supported against the supporting structure. This reliably prevents the jack receptacle from becoming accidentally detached from the supporting structure.

[0010] The invention also relates to a motor vehicle with a jacking point as described above. The motor vehicle advantageously comprises at least two, preferably four, such jacking points.

[0011] In a method for mounting a previously described jack receptacle on a motor vehicle, the above-mentioned object is achieved alternatively or additionally by at least one, several or each of the following assembly steps. First, the holding element in the open position is pre-assembled to the support structure. In this case, the holding element, which is preferably pivoted relative to the jack receptacle, is inserted, for example, into a corresponding opening in the support structure. Thereafter, the holding element pre-assembled to the support structure is clamped or locked to the jack receptacle in the closed position in order to secure the jack receptacle to the support structure. In this case, the jack receptacle is advantageously pivoted relative to the holding element until the holding element has assumed its closed position relative to the jack receptacle.After pre-assembly, the jack support, secured with the retaining element, is securely fastened to the supporting structure with at least one fastener. This fastener could be a screw, for example, that is screwed into at least one fastening element on the jack support.

[0012] Further advantages, features, and details of the invention will become apparent from the following description, in which various embodiments are described in detail with reference to the drawings. They show: Fig. 1 a perspective view of a car jack with a holding element in its closed position; Fig. 2 a perspective view of the jacking point from Fig. 1 with the holding element in its open position; Fig. 3 shows a section through a supporting structure of a motor vehicle, to which a jacking point is fastened with a holding element and a fastening means, in a longitudinal section through the fastening means; Fig. 4 a similar sectional view as in Fig. 3, but not through the fastener to show an external clamping point; and Fig. 5 a similar representation as in Fig. 4 to show an inside clamping point.

[0013] In the Fig. 1 and Fig. 2 shows a perspective view of a car jack 1 with a base body 3. Two fastening bodies 4, 5 protrude from the base body 3 into the Fig. 1 and Fig. 2 essentially upwards.

[0014] When installed, the jacking point 1 has the task of holding a jack or a lifting platform. Fig. 1 and Fig. 2 alone shown jack support 1 is in the Fig. 3 to 5 in various sectional views in their assembled state.

[0015] The fastening bodies 4, 5 essentially have the shape of straight circular cylinder shells and are advantageously designed as riveted connection elements. The support body 8 is integrally connected to the fastening bodies 4, 5 via the base body 3.

[0016] A retaining element 10, designed as a retaining plate, is integrated into the jack receptacle 1. The retaining element 10 comprises two through holes 11, 12, which serve to pass through the fastening bodies 4, 5.

[0017] In Fig. 1 shows the jack support 1 with the integrated retaining plate or the integrated retaining element 10 in its closed position. Fig. 2 the holding element 10 is shown in its open position.

[0018] Between the Fig. 1 shown closed position and the one in Fig. In the open position shown in Figure 2, the holding element 10 is movable in a defined manner. To achieve the defined movement, the holding element 10 is advantageously pivotably mounted on the base body 3 of the car jack holder 1. The pivotable mounting is preferably essentially hinge-like.

[0019] In the Fig. Figures 3 to 5 show various sectional views of a supporting structure 30 of a motor vehicle. The supporting structure 30 represents a bodyshell of the motor vehicle.

[0020] The shell 30 includes, as can be seen in Fig. 3, a total of four profile sections 31, 32, 33, 34. Profile section 31 extends essentially in a horizontal direction. Profile section 32 extends from profile section 31 essentially vertically downward.

[0021] The profile section 33 extends essentially from the profile section 32 to the right, i.e. essentially parallel to the profile section 31. On its upper side, the profile section 33 is slightly inclined.

[0022] The profile section 34 extends from the profile section 33 in Fig. 3 downwards. A support symbol 36 is Fig. 3 indicates that the jack holder 1 with the support body 8 is supported on the profile section 34 of the support structure 30.

[0023] Profile sections 31 to 33 represent a Fig. 3 is a U-profile open to the right. The holding element 10 or the holding plate 10 is located in Fig. 3 from above to the profile section 33. The jacking point 1 is located in Fig. 3 from below to the profile section 33.

[0024] The fastening body 4 extends, as can be seen in Fig. 3, through the profile section 33 and through the through-hole 11 in the holding plate 10 upwards. A fastening means 38 designed as a screw is screwed from below through the jack receptacle 1 into the fastening body 4 in order to fasten the jack receptacle 1 with the holding plate or the holding element 10 to the profile section 33 of the supporting structure 30.

[0025] For pivoting attachment, the holding element 10 can be locked to the jack holder 1. The Fig. 2 The opened jack receptacle 1 can be pushed into the support structure 30 with the retaining plate 10. There, the retaining plate or retaining element 10 clamps itself to the actual jack receptacle 1 during pre-assembly.

[0026] In Fig. Figure 4 shows a cross-sectional view of an external clamping point 41 between the retaining plate 10 and the jack receptacle 1. The external clamping point 41 includes, for example, a locking hook 42 that engages with the jack receptacle 1.

[0027] In Fig. 5, an inner clamping point 52 is visible in a further section between the holding plate or the holding element 10 and the jack receptacle 1. During pre-assembly, the holding plate 10 inserted into the open support structure 30 is clamped at the outer clamping point 41 and the inner clamping point 52 by a relative pivoting between the jack receptacle 1 and the holding plate 10.

[0028] Pre-assembly is complete as soon as the retaining plate 10 is in its closed position relative to the jack receptacle 1. The profile section 33 of the support structure 30 is then clamped between the base body 3 and the retaining plate 10.

[0029] The assembly of the pre-assembled jack support 1 is completed by screwing the fastening element 38 into the fastening body 4. Similarly, for the stable fastening of the jack support 1 to the support structure 30, another fastening element is screwed into the fastening body (5 in Fig. 1) screwed in.
