Load carrier system and clamping foot for a load carrier system

Description

[0001] The invention relates to a load carrier system for a vehicle, in particular a motor vehicle with roof rails. The load carrier system comprises a plurality of clamping feet for fastening in the roof area of ​​the vehicle, in particular to a roof rail. Each clamping foot has a base body and at least one contact area for contact with the roof rails of the vehicle. At least one clamping bolt is arranged on the base body. The invention further relates to a clamping foot for a load carrier system.

[0002] Load carrier systems are known in the art in a variety of designs. Load carrier systems typically have at least four clamping feet and two cross members. At each end of a cross member, a clamping foot is arranged for attachment to the roof or roof rails. The arrangement on the vehicle is usually such that the cross members span the roof in a direction transverse to the direction of travel of the vehicle. A load can then be directly attached to the cross members. Alternatively, there are load carrier systems that have a base plate so that a load can be attached to the base plate. Furthermore, load carrier systems are known that have a roof box, in particular with a base plate, in which a load can be arranged in the roof box and / or attached to the base plate of the roof box.

[0003] For example, US Pat. No. 5,275,320 A describes a roof rack for vehicles with a removable clamping arrangement. This clamping arrangement can be activated using a tensioning screw.

[0004] US 2016 / 332 581 A1 also describes a clamping arrangement with a clamping screw. This screw can be pivoted around its screw-in point via a cam element.

[0005] From CN 112 424 026 A a load carrier system is known which has a crossbeam with a slot extending in the longitudinal direction through which a screw is guided to a stop surface.

[0006] DE 10 2014 208 683 A1 is directed to a roof rack assembly in which movable clamping jaws enclose a support body. These clamping jaws can be tightened and released via a manually operated adjusting unit.

[0007] US Pat. No. 9,085,266 B2 describes a clamping device comprising a fastening element with a first and a second clamping section. These clamping sections correspond to one another and are movable relative to one another.

[0008] The disadvantage of the load-carrying systems known from the state of the art is that they are typically very tall, meaning they are positioned at a considerable distance from the roof surface when installed. This is disadvantageous from both an aerodynamic and driving dynamics perspective.

[0009] The present invention is therefore based on the object of specifying a load carrier system and a clamping foot for a load carrier system with which the distance to the roof surface is minimized in the assembled state.

[0010] The aforementioned object is achieved in a generic load carrier system according to the characterizing part of claim 1 in that the clamping bolt is slidably held on the base body at a first end. Preferably, the bearing point of the first end of the clamping bolt is arranged in the base body. A clamping bracket is arranged on the second end of the clamping bolt, so that a roof rail can be clamped between the clamping bracket and the contact area.

[0011] The base body of the clamping foot has a contact area for attachment to a vehicle's roof rail. The contact area is preferably at least partially curved, allowing it to be advantageously attached to the typically curved roof rails. The length of the clamping bolt is adjustable, allowing a clamping force to be exerted on the roof rail by the clamping angle and the contact area.

[0012] The contact area and the clamping angle are advantageously designed so that the clamping foot can be mounted on closed roof rails. Closed roof rails are characterized by the absence of an opening between the roof surface and the roof rail. The roof rail therefore extends directly into or onto the roof surface. The clamping foot, in particular the contact area and the clamping angle, are designed so that the roof rail does not have to be completely gripped, but rather that sufficient force is transmitted when the roof rail is resting on the side or partially gripping underneath.

[0013] Adjacent to the contact area is a connection area in which the base body can be connected, for example, to a cross member. In particular, the connection area has an outer cross-section, for example rectangular, which corresponds to the inner cross-section of the cross member, so that the connection area can be inserted into a cross member. The cross member preferably has a square or rectangular inner cross-section. The connection area preferably extends at least or exactly over approximately two-thirds of the length of the clamping foot. The base body is preferably produced by injection molding or an additive manufacturing process, for example 3D printing. The base body is at least partially made of a plastic, in particular of a glass fiber reinforced plastic, for example a plastic with at least 30% glass fiber content.

[0014] At least one clamping bolt is preferably connected to the base body. The clamping bolt is held displaceably within the base body by a first end side. "Displaceable" in this context means that the position of the first end side, i.e., the bearing point of the first end side, is changed within the base body by displacement. The base body has, for example, at least one fastening cavity that defines the limits for the displaceability of the clamping bolt, in particular the bearing point at the first end side. The clamping bolt is preferably arranged such that its first end side is translationally displaceable within the base body.

[0015] Advantageously, it is provided that the clamping bolt is translationally movable along at least one straight line. Alternatively, it is also provided that the first end side is movable along a spline-shaped or curved path. For example, the clamping bolt is movable with respect to a height direction (x-direction) of the base body in the assembly position within the base body. However, it is also provided that the clamping bolt is held so as to be movable in a lateral direction (z-direction) with respect to the base body and / or a depth direction (y-direction) with respect to the base body. Preferably, it is provided that the clamping bolt is only translationally movable in a height direction of the base body. In the usual assembly state of the clamping foot on a vehicle, the height direction is oriented from top to bottom.

[0016] The bearing point of the clamping bolt is preferably displaceable in such a way that when the first end side of the clamping bolt - the bearing point - is moved from a first end position to a second end position, at least half the height of the clamping foot, preferably two-thirds of the height, is covered.

[0017] At the second end of the clamping bolt, a clamping bracket is connected to the clamping bolt in such a way that a roof rail can be clamped between the clamping bracket and the contact area of ​​the base body in order to secure the clamping foot to the roof rail. In the assembled state, a substantially diagonally oriented clamping force between the clamping bracket and the contact area is transferred from the clamping bolt to the base body. The clamping bolt and / or the clamping bracket are preferably made of a metal, preferably a stainless metal, in particular a stainless steel.

[0018] The load carrier system preferably comprises at least one base plate that can be fastened to cross members arranged between the clamping feet. The base plate is preferably riveted or can be riveted or screwed or can be screwed to the cross members. The base plate has a shape such that it engages over the roof rails of the vehicle. In particular, the base plate only rests against the vehicle in the area of ​​the windshield and is otherwise advantageously spaced all the way around from the vehicle roof. It is further preferably provided that the base plate is the base plate of a roof box, wherein a cover element can be connected to the base plate of the roof box. The cover element can preferably be pivotably connected or connected to the base plate. The base plate can be fastened to the cross members of the load carrier system. The cover element can be fastened to the base plate, advantageously pivotably.For example, the lid element can be connected to the base plate via pivoting lid supports.

[0019] In particular, it is provided that the length of the roof box formed by the base plate and the cover element is adjustable, in particular by the cover element and the base plate having at least one joint at which the base plate and the cover element can be cut to the desired length, so that the two elements can then be joined together by gluing. In this way, the length of the base plate and / or the roof box can be individually adjusted to the vehicle length.

[0020] The load carrier system preferably has at least, in particular exactly four, at least six, in particular exactly six, or at least eight, in particular exactly eight, clamping feet.

[0021] For example, it is provided that the load carrier system has at least four, in particular exactly four, clamping feet and at least two, in particular exactly two, support feet, or at least four, in particular exactly four, support feet. The support feet serve only for stabilization and, when installed, rest against the roof rail. Preferably, the support feet are designed essentially like the clamping feet, with the exception that there are no tension bolts. Furthermore, it is also provided that the load carrier system has at least six, in particular exactly six, clamping feet and at least two, in particular exactly two, support feet.

[0022] Compared to prior art load carrier systems, the invention has the advantage that the clamping feet are designed to be very flat due to the movable clamping bolt. This allows the load carrier system to be positioned very close to the vehicle's roof when installed. This has a beneficial effect on the vehicle's aerodynamics and, due to the low center of gravity, on its driving dynamics. The movable clamping bolt also ensures advantageous adaptability to roof rails with different cross-sections.

[0023] According to one embodiment of the load carrier system, the clamping bolt is pivotably mounted at least at its first end. The clamping bolt is pivotably mounted, for example, in the vertical and / or lateral direction. Preferably, the clamping bolt is pivotably mounted only in the vertical direction. Preferably, the clamping bolt is pivotable in an imaginary pivot plane. The pivot plane preferably includes the vertical direction. Particularly preferably, the clamping bolt is pivotably and displaceably mounted in the base body at one end. This simplifies assembly and enables adaptation to different roof rail shapes.

[0024] According to a further embodiment of the load carrier system, it has proven particularly advantageous if the clamping bolt is pivotable at its first end side within an angular range of at least 30°, in particular at least 45°, preferably at least 60°. It is provided that the angular range - due to the displaceability of the first end side - can relate to different positions of the first end side in the base body. The entire angular range therefore does not have to be coverable in every position, but the entire angular range can also only be reached by displacement. The angle that can be covered by the clamping bolt, in particular in a pivoting plane, is preferably at least 30°, in particular at least 45°, particularly preferably at least 60°. A further development also provides that the clamping bolt is held so as to be pivotable within an angular range of up to 60°.

[0025] A particularly advantageous balance between stability and ease of assembly can be ensured according to a further embodiment in that the clamping bolt can be pivoted at its first end side, in particular starting from a substantially horizontal position, in particular in the assembled state, between an angle of +30° and -30°. Consequently, in the assembled state of the load carrier system, the clamping bolt can be pivoted upwards by approximately 30° and downwards by approximately 30°. The total traversable angle is then 60°. As described above, it is provided that both angles can only be achieved if the first end side is shifted to a lower position for a first angle of +30°, for example, and to an upper position for a second angle of -30°. The horizontal reference position therefore shifts with the first end side, in particular its bearing point.

[0026] Particularly preferably, the clamping bolt is pivotable between an angle of +25° and -15°. It is also provided that the clamping bolt is pivotable, in particular, between an angle of +19.5° and -7°. The clamping bolt can therefore be pivoted upwards by approximately 19.5° and downwards by approximately 7°. The angle specification always refers to the bearing point of the clamping bolt in the base body, which—as described above—is held displaceably, in particular translationally displaceably.

[0027] According to a further embodiment of the load carrier system, the clamping bolt is mounted at its first end in a transversely threaded bolt. The transversely threaded bolt is preferably designed as a cylindrical bolt having at least one recess with an internal thread in its transverse extension. In this way, the clamping bolt can preferably be screwed into the transversely threaded bolt, so that the clamping bolt can subsequently be pivoted about the longitudinal axis of the transversely threaded bolt. The transversely threaded bolt is preferably held in a fastening cavity of the base body so that it can be moved translationally, in particular in a vertical direction. In this way, both the displaceability and the pivotability of the clamping bolt are realized. The shape of the fastening cavity limits the displaceability of the transversely threaded bolt.The second end side with the clamping angle is therefore freely movable within the limits given by the fastening and limited by the base body.

[0028] A further embodiment of the load-bearing system provides that the clamping bolt has at least one clamping screw, in particular with an external thread, and at least one clamping sleeve, in particular with a corresponding internal thread. The clamping sleeve preferably has an external thread on a first end, with which the clamping sleeve can be screwed into the transversely threaded bolt. The clamping sleeve is attached to the transversely threaded bolt. The clamping screw preferably passes through the clamping bracket and is screwed with its external thread to the internal thread of the clamping sleeve. In this way, the length of the clamping bolt and thus the clamping force can be adjusted by means of a screw.

[0029] According to a further embodiment of the load carrier system, the clamping bolt has at least one guide sleeve, and the guide sleeve at least partially surrounds the clamping screw, in particular in the region of the external thread, and / or the clamping sleeve. Preferably, the guide sleeve at least partially surrounds both the clamping screw and the clamping sleeve. Preferably, the guide sleeve rests on the outer circumference of the clamping sleeve. The degree of overlap is determined in particular by the degree to which the clamping screw is screwed into the clamping sleeve. The guide sleeve advantageously prevents dirt from penetrating the clamping bolt.

[0030] For interaction with the clamping angle, it has proven advantageous if the guide sleeve has at least one stop collar, and if the guide sleeve, with the stop collar, rests in a recess on the clamping angle. The clamping angle preferably has at least one recess through which the clamping bolt, in particular the guide sleeve and the clamping screw, pass.

[0031] Advantageously, the clamping bracket is arranged on the clamping bolt between the stop collar of the guide sleeve and an annular fastening element. For example, the fastening element is pressed onto the guide sleeve. The clamping screw is inserted into the guide sleeve and screwed into the internal thread of the clamping sleeve. Advantageously, at least one washer is arranged between a head of the clamping screw and the guide sleeve, in particular the stop collar of the guide sleeve.

[0032] The load carrier system according to the present invention is preferably further developed in that at least two crossbeams are provided. A clamping foot is preferably arranged at each end of a crossbeam. The clamping feet of a crossbeam are movable in the crossbeam to adjust a clamping width on a vehicle roof and can be continuously fixed. For this purpose, the base body of a clamping foot is preferably at least partially inserted into the inner circumference of a crossbeam at one end. The crossbeam preferably has at least one adjusting screw at one end, which is guided in a guide groove with an opposite clamping block in the base body. The base body has a corresponding guide groove so that the penetration depth of the clamping foot, in particular of the base body of the clamping foot, into the crossbeam can be continuously adjusted and fixed in the set position.

[0033] Each cross member is preferably at least partially curved, in particular curved with a radius. For example, starting from each end side of the cross member, the cross member is completely straight, with the middle third of each cross member having a curve. The cross member is preferably curved such that, in the assembled state, it extends convexly away from the vehicle roof.

[0034] According to a further embodiment, it has proven advantageous to provide at least eight clamping feet for attaching a base plate to the load-carrying system. Four of the eight clamping feet can each be connected to two crossbeams. A further four of the eight clamping feet can be connected to a support beam. Preferably, four support beams and two crossbeams are provided. The clamping feet are, in particular, of identical design.

[0035] Preferably, at least two, in particular exactly two, cross beams are provided, so that at least one clamping foot is arranged at each end region of a cross beam. The support beams are designed similarly to a cross beam. Each support beam has a length that corresponds to a partial length of a cross beam. Preferably, a support beam has a length that corresponds approximately to one third of the length of a cross beam. The cross section of the support beam corresponds, for example, to the cross section of the cross beam. Each clamping foot can be inserted at least partially into a support beam, in particular with its base body, and can be moved and continuously fixed in the support beam to adjust a clamping width. The corresponding mechanism is designed as described above for the cross beams.

[0036] Preferably in systems in which a base plate is fastened to the cross members, it has proven advantageous according to a further embodiment if at least two, in particular four, vibration damping means are provided. The vibration damping means are fastened to the cross members and / or to the support members in such a way that they extend in a plane below the base plate and bear against the base plate from below. The vibration damping means are designed, for example, in the form of vibration damping angles which, for example, cover an angle of approximately 90°, so that in the assembled state they extend essentially perpendicularly in a plane away from the cross member and / or the support member. It is preferably provided that at least one vibration damping means, in particular in the form of a vibration damping angle, is fastened to each of the four support members.Preferably, the cross members are arranged in the center, while the support beams are mounted at the front and rear, respectively. In this way, vibration of the floor panel during travel, particularly due to wind influences, can be advantageously prevented in the assembled state, preferably in the assembled state of a floor panel.

[0037] According to one embodiment of the load carrier system, the base body has at least one substantially U-shaped recess, and the clamping bolt is arranged in the U-shaped recess. The clamping bolt preferably extends substantially parallel to the two—imaginary—U-shaped legs of the U-shaped recess. Furthermore, it is particularly provided that the base body has at least one ramp, particularly in the region of the U-shaped recess. The ramp represents a recess in the material of the base body and enables pivoting of the clamping bolt within the angular ranges described above.

[0038] A further embodiment of the load carrier system provides for a counterholder to be arranged on the clamping bolt. The counterholder is arranged on the clamping bolt in the longitudinal direction of the clamping bolt at a distance from the clamping angle. The counterholder initially extends away from the clamping bolt preferably essentially orthogonally to the longitudinal direction of the clamping bolt and has an angle in its end region facing away from the clamping bolt. The angle preferably extends in the direction of the clamping angle and interacts with it. The counterholder therefore contacts the clamping angle at a distance from the clamping bolt, in particular at a distance in the radial direction. The counterholder is preferably arranged on the guide sleeve of the clamping bolt. For example, the counterholder is connected to the clamping bolt, in particular to the guide sleeve, in a form-fitting, force-fitting, and / or material-fitting manner.

[0039] The clamping bracket advantageously has an effective area in which it can interact with a railing of a vehicle when installed. The effective area is arranged in particular on a first side of the clamping bolt or a longitudinal axis of the clamping bolt. The counterholder advantageously interacts with the clamping bracket on a second side opposite the clamping bolt or the longitudinal axis of the clamping bolt, so that the clamping bracket can be supported on the counterholder when force is applied by a railing. The clamping bracket is supported, in particular in the installed state, on the counterholder, so that a greater force can be transmitted with the clamping bracket.

[0040] A further advantageous embodiment provides that the counterholder is non-rotatably attached to the clamping bolt. For example, the counterholder is non-rotatably connected to the clamping bolt, in particular to the guide sleeve of the clamping bolt, in a force-fitting, form-fitting, and / or material-fitting manner. It is advantageously provided that the counterholder interacts non-rotatably with the clamping angle, preferably in a form-fitting manner. The counterholder preferably has an angle in an end region facing away from the clamping bolt. For example, the angle has at least one recess that interacts with a projection of the clamping angle.

[0041] Preferably, the recess is slightly wider than the projection, allowing the clamping wedge to rotate within the recess. The counterholder serves primarily as an assembly aid and ensures anti-twist protection for the clamping wedge.

[0042] The invention further relates to a clamping foot, in particular for a load carrier system according to one of the embodiments described above, advantageously designed according to one of the embodiments described above.

[0043] Further advantageous embodiments of the invention emerge from the following description of the figures and the dependent subclaims.

[0045] In the various figures of the drawing, identical parts are always provided with the same reference symbols.

[0046] The scope of the invention is determined by the patent claims. However, the description and drawings are to be used to interpret the patent claims.

[0047] Fig. 1 shows an embodiment of a load carrier system 1 for a vehicle (not shown) in perspective view. The load carrier system 1 has a plurality of clamping feet 2 for fastening in the roof area of ​​the vehicle. Each clamping foot 2 has a base body 3 and a contact area 4 for attachment to a roof rail (not shown) of a vehicle. At least one clamping bolt 5 with a clamping angle 6 is arranged on each base body 2. In the assembled state, a roof rail can be clamped between the clamping angle 6 and the contact area 4, whereby the load carrier system 1 is fastened to the vehicle.

[0048] The clamping feet 2 of the embodiment of the Fig. 1 are in the Fig. 2 , 3 and 4 shown separately in different views. Fig. 2 shows a clamping foot 2 with clamping bolt 5 and clamping angle 6, Fig. 3 shows the clamping foot 2 without the clamping bolt 5 and the clamping angle 6. According to Fig. 2 and 3 The clamping base 2 has a contact area 4 for attachment to a roof rail of a vehicle. The contact area 4 is formed on a first end side 7 of the base body 3.

[0049] Adjacent to the first end side 7, the base body 3 has a connecting area 8 which has an outer contour which allows the base body 3 to be inserted into a Fig. 1 The connecting region 8 has a longitudinally extending and centrally arranged guide groove 11, which cooperates with a clamping block (not shown) of a fastening screw 12 such that the base body 3 can be fixed in its position relative to the cross member 9 or the support member 10, whereby the load carrier system 1 can be adjusted to a vehicle width or a railing distance of a vehicle. To make it easier for a user to adjust to the vehicle width, a scale 13 is also formed on the base body 3, in particular on the connecting region 8.

[0050] Fig. 4 shows an embodiment of a clamping foot 2 in longitudinal section. The base body 3 is essentially formed as a single piece, injection-molded part, and is covered at the first end 7 with a cover 14. A guide cavity 15 is formed between the first end 7 and the connecting area 8. Arranged in the guide cavity 15 is a transversely threaded bolt 16, into which the clamping bolt 5 with the external thread 17 of a clamping sleeve 18 is screwed.

[0051] The transverse threaded bolt 16 is guided in the guide cavity 15 in such a way that it is guided in a height direction H - along the double arrow according to Fig. 4 and parallel to the x-direction - between a first end position 15a and a second end position 15b. Preferably, the transverse threaded bolt is held immobile in the z-direction and y-direction, in particular apart from any necessary play. The transverse threaded bolt 16 is displaceable approximately over half the height of the base body 3. Because the transverse threaded bolt 16 is movable in a translational vertical direction in the clamping foot 2 or in the base body 3, the clamping bolt 5 is movable within an angular range of +26° and -18°, starting from a horizontal line that essentially coincides with the longitudinal axis L. The horizontal line for determining the respective angle shifts with the bearing point of the first end side of the clamping bolt 5, here the transverse threaded bolt 16.

[0052] Fig. 4 shows the clamping bolt 5 at an angle α of approximately +8°. To enable the pivotability of the clamping bolt 5 within the aforementioned angular range of approximately 44°, the base body 3 has a ramp 19, which expands the range of motion when pivoting the clamping bolt 5.

[0053] In this way, the clamping bracket 6 can assume a variety of orientations in order to clamp a roof rail together with the contact area 4. In this exemplary embodiment, the clamping bolt 5 further comprises a clamping screw 20, the external thread 21 of which is screwed into a corresponding internal thread 22 of a clamping sleeve 18. Both the clamping screw 20 and the clamping sleeve 18 are surrounded by a guide sleeve 23. The guide sleeve 23 has a stop collar 24, with which the guide sleeve 23 rests in a recess 25 in the clamping bracket 6. The clamping bracket 6 is fixed relative to the guide sleeve 23 with a fastening element 26. The fastening element 26 is pressed on.

[0054] A washer 27 is arranged between a head of the clamping screw 20 and the stop collar 24. The length of the clamping bolt 5 can be adjusted by means of the clamping screw 20 by screwing it into the clamping sleeve 18. To prevent the clamping bolt 5 from becoming loose from the transversely threaded bolt 16 when the length is adjusted via the clamping screw 20, a counter screw 36 is screwed into the clamping sleeve 18 at the front of the first end of the clamping bolt 5. Due to the flat base body 3 and the displaceability of the clamping bolt 5 at its first end, the present load carrier system 1 has a low overall height compared to load carrier systems known from the prior art.

[0055] To stabilize the clamping bracket 6, it has stabilizing deformations 28. To prevent damage to roof rails, a protective rubber 29 is arranged on the clamping bracket 6. The connecting area 8 of the base body 3 has a guide groove 11. Below the guide groove 11, the connecting area 8 is formed with cavities 37 to reduce the weight of the base body 3.

[0056] Fig. 5 shows the embodiment of a load carrier system 1 according to Fig. 1 with partially assembled base plate 30. The base plate 30 has two mounting rails 31 for securing loads, such as luggage. The base plate 30 is connected, for example, screwed or riveted, to the cross members 9 and the support beams 10. The base plate 30 also has two hinges 32 for interacting with a lid for a roof box.

[0057] Fig. 6 shows a fully assembled base plate 30 on a load carrier system 1, in which the base plate 30 is completed with side part elements 33 to completely cover a roof rail (not shown) and thus improve the aerodynamics of the load carrier system 1. The base plate 30 is preferably designed such that, in the assembled state, it only rests in the area of ​​the vehicle's windshield. This prevents damage to painted surfaces. A damping means, such as a rubber, is preferably arranged between the base plate and the windshield.

[0058] According to Fig. 1 A vibration damping means 34 in the form of a vibration damping angle is provided on each of the support beams 10, which reduces the vibration of the base plate 30 in the front and rear areas of the load carrier system 1 when the base plate 30 is mounted. The vibration damping means 34 are according to Fig. 1 attached to the support beams 10 in such a way that they extend in the direction of the front and rear of the vehicle in the assembled state.

[0059] According to Fig. 2 and 3 The base body 3 has a U-shaped recess 35 into which the clamping bolt 5 extends. A ramp 19 is formed in the lower region of the U-shaped recess, which extends the pivoting range of the clamping bolt 5.

[0060] Fig. 7 and 8 show a sectional view through an embodiment of a clamping foot 2. Fig. 7 shows the clamping bolt 5 in a first angular position, while the transverse threaded bolt 16 is arranged in the first end position 15a; Fig. 8 the clamping bolt 5 in a second angular position, while the transverse threaded bolt 16 is arranged in the second end position 15b. The angular range that the clamping bolt 5 can cover – at different positions of the transverse threaded bolt 16 in the guide cavity 15 – is approximately 26.5°. When considering the angular range, the angles α in the first end position 15a upwards and in the second end position 15b downwards are added together as a value.

[0061] Fig. 7 shows the clamping bolt 5 at an angle α of approximately +19.5°. Fig. 8 shows the clamping bolt 5 at an angle α of approximately -7°. The position of the transverse threaded bolt 16 varies in each case. The angle α is always measured from a substantially horizontal line. The horizontal line is always at least parallel to the longitudinal axis L - see Fig. 4 - or to the y-direction.

[0062] Due to the displaceability of the transverse threaded bolt 16 within the guide cavity 15, the clamping bolt 5 - while maintaining a flat design of the clamping foot - can assume a variety of orientations in order to clamp a roof rail together with the contact area 4 and to assemble the load carrier system 1. The clamping bolt 5 has a clamping screw 20, the external thread 21 of which is screwed into a corresponding internal thread 22 of a clamping sleeve 18. Both the clamping screw 20 and the clamping sleeve 18 are surrounded by a guide sleeve 23. The guide sleeve 23 has a stop collar 24 with which the guide sleeve 23 rests in a recess 25 in the clamping bracket 6. The clamping bracket 6 is fixed relative to the guide sleeve 23 with a fastening element 26. The fastening element 26 is pressed on.

[0063] A washer 27 is arranged between a head of the clamping screw 20 and the stop collar 24. The length of the clamping bolt 5 can be adjusted by means of the clamping screw 20 by screwing it into the clamping sleeve 18. To prevent the clamping bolt 5 from becoming loose from the transversely threaded bolt 16 when the length is adjusted via the clamping screw 20, a lock screw 36 is screwed into the clamping sleeve 18 at the front end of the first end of the clamping bolt 5.

[0064] Fig. 9 and Fig. 10 show an embodiment of a clamping foot 2, Fig. 9 in sectional view, Fig. 10 in perspective view. In this embodiment, a counterholder 38 is arranged on the clamping bolt 5, along the longitudinal axis of the clamping bolt 5, spaced from the clamping angle 6. The counterholder 38 is connected in a rotationally fixed manner to the clamping bolt 5, in particular to the guide sleeve 23. The clamping angle 6 has an effective area 6a, which cooperates with a railing in the assembled state. The protective rubber 29 is preferably also arranged in the effective area 6a. The effective area 6a extends on a first side - according to Fig. 9 and 10 below - the clamping bolt 5.

[0065] The counterholder 38 extends from the clamping bolt 5 to a second side opposite the first side with respect to the clamping bolt 5 or its longitudinal axis. In an end region facing away from the clamping bolt 5, the counterholder 38 has an angle 38a. The angle 38a interacts with the clamping angle 6 in that the clamping angle 6 and the counterholder 38 bear against one another. In this way, when a force is applied from a railing in the effective area 6a on the opposite, second side, the clamping angle 6 can be supported on the counterholder 38, thereby increasing stability in the assembled state.

[0066] The counterholder 38 has a recess 39 at its angle 38a, which interacts with a projection 40 on the clamping angle 6, in that the projection 40 is arranged in the recess 39. The interaction between the recess 39 and the projection 40 not only provides an assembly aid but also provides anti-twist protection for the clamping angle 6. The counterholder 38 is fastened to the clamping bolt 5 in a rotationally fixed manner. In this embodiment, the recess 39 is slightly wider than the projection, allowing a certain rotational alignment of the clamping angle 6 during assembly.

[0067] The scope of the invention is determined by the patent claims. However, the description and drawings are to be used to interpret the patent claims. Bezugszeichen
