Description

[0001] The invention relates to a carrier system for transporting and / or for stationary storage of at least one bicycle with the preamble features of claim 1.

[0002] A carrier system with the features outlined in claim 1 is known from US patent 2018 / 0265014 A1.

[0003] Another carrier system is known, for example, from DE 10 2019 208 542 A1 and is designed as a rear-mounted carrier system for transporting bicycles. The known carrier system has a base frame in the form of a carrier profile, which can be mounted to the vehicle by means of two extension profiles. Several profile rails are supported on the carrier profile, each designed to hold a front and / or rear wheel of the bicycles to be transported. The profile rails each form a longitudinally extended mounting track. The known carrier system also has a holding device in the form of a support bracket. The support bracket is U-shaped and is hinged relative to the carrier profile, allowing it to be moved between a functional position extending approximately orthogonally to the carrier profile in the vertical direction and a non-functional position folded flat against the carrier profile.For this purpose, the support bracket is pivotally connected to the carrier profile about a pivot axis. The pivot axis is oriented parallel to the longitudinal direction of the recording tracks.

[0004] Another carrier system with a foldable holding device is known from FR 2 829 082 A1.

[0005] The object of the invention is to provide a carrier system of the type mentioned above which has improved properties compared to the prior art and in particular enables an improved mounting of at least one bicycle.

[0006] This problem is solved by providing a support system with the features of claim 1. According to the invention, the holding device comprises a multi-section folding frame extending laterally offset to the receiving track, with at least one first frame section pivotally mounted to the base frame and a second frame section pivotally connected to the first frame section. The frame sections can be folded and unfolded relative to each other and relative to the base frame between the functional and non-functional positions in a folding plane extending substantially longitudinally and vertically. The folding frame according to the invention offers improved stability and thus better support for the at least one bicycle compared to conventional support brackets.Compared to conventional support brackets, the folding frame according to the invention can absorb the forces occurring when holding at least one bicycle significantly better. The base frame is designed differently depending on the specific embodiment. For example, the base frame can be a frame construction assembled from several frame profiles, a platform extending in the longitudinal and transverse directions, or the like. If the carrier system is designed for transporting at least one bicycle, the base frame preferably has a fastening device for detachably attaching the base frame to a motor vehicle. The fastening device can, for example, be designed for attachment to a ball joint head of a trailer hitch of the motor vehicle. The at least one mounting track can be a longitudinally extending track in the geometric sense and / or be formed by a physically present component.In one embodiment, the receiving track is formed by a rail- or trough-shaped component and / or a rail- or trough-shaped section of the base frame. In another embodiment, the receiving track is an imaginary line extending longitudinally along the base frame, along which the at least one bicycle is placed on the base frame for transport and / or storage. In the use of the carrier system, the longitudinal direction of the bicycle to be transported and / or stored is oriented parallel to the longitudinal direction of the at least one receiving track. The folding frame primarily serves to absorb longitudinal and lateral forces. The folding frame has several frame members, namely at least the first frame member and the second frame member. The first frame member is hinged to the base frame, and the second frame member is hinged to the first frame member.The folding plane of the resulting movement and / or folding mechanism of the folding frame extends essentially in the longitudinal and vertical directions. Accordingly, the respective pivot axes of the first and second frame members are each oriented essentially in the transverse direction. Preferably, the folding plane extends parallel to the longitudinal and vertical directions, so that it can also be referred to as a vertical longitudinal plane. In this case, the respective pivot axes of the first and second frame members are oriented parallel to the transverse direction. During a folding movement between the functional and non-functional positions, the frame members move within the folding plane. In the functional position, the folding frame projects vertically from the base frame and is thus unfolded and / or extended.In its non-use position, the folding frame is folded up and, in particular, compactly positioned against the base frame in the vertical direction. The folding frame can also be described as a multi-hinged frame. Since the folding frame has a third frame member in addition to the first and second frame members, it can also be referred to as a frame quadrilateral and / or a four-hinged frame. The longitudinal, vertical, and transverse directions are each orthogonal to one another and form a spatial Cartesian coordinate system. Preferably, the first frame member extends longitudinally between a first end and a second end, with the first end pivotally mounted to the base frame about a first pivot axis. Preferably, the second frame member extends longitudinally between a first end and a second end, with the first end pivotally connected to the second end of the first frame member about a second pivot axis.

[0007] In this embodiment of the invention, the second frame member is detachably rigidly connected to the base frame at one end, at least in the functional position. "Rigidly" here means not hinged and / or immobile. At the other end, the second frame member is hingedly connected to the first frame member. The rigid connection to the base frame can be positive-locking and / or friction-locking. To move the folding frame from the functional position to the non-functional position, the aforementioned connection between the second frame member and the base frame can be released, preferably manually. The rigid, detachable connection of the second frame member to the base frame in the functional position prevents the folding frame from being unintentionally moved into the non-functional position.

[0008] In a further embodiment of the invention, the second frame member is detachably rigidly connected at one end to a first connecting section of the base frame in the functional position and at the other end to a second connecting section of the base frame in the non-functional position. The first connecting section and the second connecting section of the base frame are spaced apart from each other along the longitudinal direction. Preferably, the second connecting section is positioned closer to the pivot point between the first frame member and the base frame than the first connecting section, with respect to the longitudinal direction. At the other end, the second frame member is pivotally connected to the first frame member. The detachable connection of the second frame member to the base frame in the non-functional position particularly counteracts unintentional displacement of the folding frame towards the functional position.The rigid, detachable connection of the second frame member to the first connecting section and the second connecting section can each be force-fit and / or form-fit. The detachable connection between the base frame and the second frame member is preferably designed as a locking bolt connection.

[0009] In a further embodiment of the invention, a locking device is provided by means of which the second frame member is detachably locked at one end to the base frame, at least in the functional position. The locking device serves in particular to secure a detachable connection between the second frame member and the base frame in the functional position. The locking device prevents unintentional loosening of said connection. To loosen the connection, the locking device must first be released and / or the locking mechanism disengaged. Only then can the connection be loosened.

[0010] In a further embodiment of the invention, an additional receiving track extending longitudinally parallel to the receiving track is provided, with the folding frame arranged transversely between the two receiving tracks. This additional receiving track serves to hold a front and / or rear wheel of another bicycle. The folding frame is arranged transversely between the two receiving tracks and thus also between the two bicycles to be transported and / or stored. In this respect, the folding frame is associated with both bicycles. This enables a particularly simple and compact design of the carrier system. Regarding further features of the additional receiving track, reference is made to the descriptions already given for the receiving track.

[0011] In a further embodiment of the invention, the first frame member, in its functional position, extends longitudinally at least predominantly in the vertical direction, and in its non-functional position, it extends longitudinally at least predominantly in the longitudinal direction. In other words, in its functional position, the first frame member is folded upwards from the base frame and thus extends longitudinally at least predominantly in the vertical direction. In its non-functional position, the first frame member is folded against the base frame and thus extends longitudinally at least predominantly in the longitudinal direction. Preferably, in its functional position, the first frame member extends longitudinally parallel to the vertical direction and / or parallel to the longitudinal direction in its non-functional position.

[0012] In a further embodiment of the invention, the second frame member is extended longitudinally at least predominantly in the longitudinal direction in the functional position and at least predominantly in the longitudinal direction in the non-functional position. In the functional position, the second frame member is spaced further away from the base frame in the vertical direction than in the non-functional position. In both positions, the second frame member is extended longitudinally at least predominantly, i.e., the main direction of extension of the second frame member is oriented longitudinally. This does not preclude the possibility that the frame member is extended longitudinally at least partially inclined to the longitudinal direction in the functional and / or non-functional position.

[0013] In a further embodiment of the invention, the first frame member extends continuously straight along its entire length between a first end and a second end. Such a continuously straight longitudinal extension allows, in particular, simplified and therefore cost-effective manufacturing.

[0014] In a further embodiment of the invention, the second frame member is at least simply angled and comprises a first frame section and a second frame section, wherein, in the functional position, the first frame section extends longitudinally parallel to the longitudinal direction, and the second frame section extends longitudinally inclined from the first frame section in the vertical direction from top to bottom and in the longitudinal direction from back to front. Such a shape and orientation of the second frame member allows, in particular, improved stability of the folding frame in the functional position. Furthermore, the space required in the non-functional position can be further reduced. Preferably, the first frame section and the second frame section each extend continuously in a straight longitudinal direction. The first frame section is pivotally connected to the first frame member at one end and rigidly connected to the second frame section at the other end.The second frame section is rigidly connected to the first frame section at one end. At the other end, the second frame section is preferably detachably rigidly connected to the base frame. This is the case, at least, in the functional position.

[0015] According to the invention, the folding frame further comprises a third frame member, which is pivotally mounted to the base frame at one end, has a handle section for gripping the front or rear wheel at the other end, and is also pivotally connected to the second frame member. The pivot point of the third frame member with the second frame member is located between the handle section and the base frame, and thus between the two ends of the third frame member. The handle section interacts with the front or rear wheel when the support system is in use. For example, the handle section can be designed in a hook or claw shape and configured to grip the front or rear wheel rim of the bicycle. Due to the pivotal connection with the base frame on the one hand and the second frame member on the other, the third frame member is guided when the second frame member is moved, and vice versa.In its functional position, the third frame member preferably projects predominantly upwards from the base frame. In its non-functional position, the third frame member is preferably folded compactly against the base frame.

[0016] In a further embodiment of the invention, the third frame member, in its functional position, projects from the base frame vertically from bottom to top and longitudinally from back to front. This orientation of the third frame member in its functional position provides even greater stability of the folding frame in this position.

[0017] Further advantages and features of the invention will become apparent from the claims and from the following description of a preferred embodiment of the invention, which is illustrated with reference to the drawings. Fig. Figure 1 shows a schematic perspective view of an embodiment of a carrier system according to the invention for a bicycle, wherein the carrier system has a base frame and a holding device in the form of a multi-part folding frame, Fig. 2 in schematic perspective representation the support system according to Fig. 1, wherein the folding frame assumes an open functional position, Fig. 3. In a schematic perspective representation, the support system according to the Fig. 1 and Fig. 2, wherein the folding frame assumes an intermediate position moving from the functional position towards the base frame, Fig. 4 in schematic perspective representation the support system according to the Fig. 1 to 3, wherein the folding frame assumes a folded, non-used position, and Fig. 5, Fig. 6, Fig. 7 each in a partially cut-off, schematic perspective view of the support system according to the Fig. 1 to 4 in a front area of ​​the base frame, with the folding frame in the functional position ( Fig. 5), the intermediate position ( Fig. 6) and assumes the non-use position ( Fig. 7).

[0018] According to Fig. 1 is a carrier system 1 for transporting and / or for stationary storage of at least one bicycle F. As detailed below. Fig. As shown in Figures 2 to 7, the support system 1 has a base frame 2, at least one recording track S1 and a folding frame 3.

[0019] In the illustrated embodiment, the base frame 2 is designed both for mounting on a motor vehicle (not shown in detail) and for placement on a flat surface (not specified in detail). For mounting on the motor vehicle, the base frame 2 has a fastening device (not shown in detail) that allows the base frame 2 to be detachably attached to a rear section or the roof of the motor vehicle. Such fastening devices are generally known to those skilled in the art. Moreover, the method of attaching the base frame 2 to the motor vehicle is not important with regard to the present invention, so further explanations in this respect are unnecessary. For placement on the ground, the base frame 2 can have several support feet or the like arranged on its underside, which ensure that the base frame 2 stands securely.This aspect is also of minor importance with regard to the present invention, so further explanations in this regard are omitted.

[0020] The receiving track S1 is arranged on the base frame 2 and extends longitudinally in the X direction. The receiving track S1 serves to receive the front and rear wheels of the bicycle F ( Fig. 1) In the embodiment shown, the receiving track S1 is formed by a wheel rail 4, which is attached to the base frame 2 in a manner not shown in detail. In an embodiment not shown in the drawing, the receiving track S1 is a track and / or line in the geometric sense along which the bicycle F is placed on or pushed onto the base frame 2. In the embodiment shown in the drawing, the following applies: Fig. In the configuration shown in 1, the recording track S1 and a track of the bicycle F formed by the front and rear wheels are coaxially oriented.

[0021] The folding frame 3 is in a functional position relative to the base frame 2 ( Fig. 1, Fig. 2, Fig. 5) and a non-use position ( Fig. 4, Fig. 7) relocatable. In the functional position, the folding frame 3 projects upwards from the base frame 2 to hold the bicycle F in the vertical direction Z. In the non-functional position, the folding frame 3 is moved compactly against the base frame 2 to reduce the space required by the carrier system 1.

[0022] In the based Fig. In the configuration shown in Figure 1, the bicycle F is attached to the folding frame 3 by means of a clamping device 5. The clamping device 5 has a function and design generally known to those skilled in the art and engages the bicycle F, more precisely its down tube, at one end and the folding frame 3 at the other. In this way, the forces occurring when the bicycle F is mounted can be transferred in the longitudinal direction X and in the transverse direction Y to the folding frame 3 and from there to the base frame 2. In other words, the folding frame 3 primarily serves to absorb longitudinal and transverse forces. Conversely, the base frame 2 primarily absorbs the weight force of the bicycle F acting along the vertical direction Z.

[0023] The folding frame 3 extends laterally in the transverse direction Y relative to the receiving track S1. Furthermore, the folding frame 3 is designed with multiple sections and comprises at least a first frame section 6 and a second frame section 7. The two frame sections 6, 7 can be folded and unfolded between the functional and non-functional positions in the longitudinal direction X and in the vertical direction Z relative to each other and relative to the base frame 2. The hinge and / or movement mechanism of the folding frame 3, which will be described in more detail below, accordingly has a folding plane extending in the longitudinal direction X and in the vertical direction Z. In other words, the folding plane of the folding frame 3 is a vertically oriented longitudinal plane and / or XZ plane. In the embodiment shown, the folding plane of the folding frame 3 coincides with the vertical central longitudinal plane of the support system 1.

[0024] In order to ensure the aforementioned folding mobility of the folding frame 3, the first frame member is hinged at one end on the base frame 2 and the second frame member 7 is hinged to the first frame member 6.

[0025] The first frame member 6 is pivotally mounted at one end on the base frame 2 about a first pivot axis G1. At the other end of the first frame member 6, the folding frame 3 has a second pivot axis G2, about which the first frame member 6 and the second frame member 7 are pivotally movable relative to each other. The first pivot axis G1 and the second pivot axis G2 are each oriented parallel to the transverse direction Y.

[0026] In the embodiment shown, the second frame member 7 is at least in the functional position ( Fig. 1, Fig. 2, Fig. 5) at its end furthest from the first frame member 6, the frame is detachably and rigidly connected to the base frame 2. To move the folding frame 3 into the non-use position, the said connection between the second frame member 7 and the base frame 2 can be released in a manner described in more detail below.

[0027] Further structural and functional features of the support system 1 are explained in detail below. These features are considered advantageous, but not essential with regard to the present invention.

[0028] In the illustrated embodiment, the base frame 2 has a further receiving track S2. This additional receiving track S2 extends longitudinally parallel to the receiving track S1. The receiving tracks S1 and S2 can also be referred to as the first receiving track S1 and the second receiving track S2. The second receiving track S2 serves to hold another bicycle, which is not shown in detail.

[0029] The folding frame 3 is arranged transversely Y between the first mounting track S1 and the second mounting track S2 and is assigned to both mounting tracks S1 and S2. This eliminates the need for a separate holding device or a separate folding frame for holding a bicycle mounted on the second mounting track S2. A further clamping device 5' is provided for holding another bicycle assigned to the second mounting track S2 and is attached at one end to the folding frame 3.

[0030] The second receiving track S2 is formed by a second wheel rail 4'. The statements made regarding the first wheel rail 4 apply analogously to the second wheel rail 4'. In the compact, unused position, the folding frame 3 is lowered at least partially in the vertical direction Z between the two wheel rails 4, 4' and thus also the receiving tracks S1, S2 formed by them.

[0031] In embodiments not shown in detail in the drawings, the support system has either only one receiving track or more than the two receiving tracks shown here. For example, if three parallel longitudinally extending receiving tracks are provided, it is advantageous to have two corresponding hinged frames.

[0032] In the illustrated embodiment, the first frame member 6 extends longitudinally between a first end 61 and a second end 62. The first pivot axis G1 is located at the first end 61. The second pivot axis G2 is located at the second end 62. In the illustrated embodiment, the first frame member 6 extends continuously in a straight line between its first end 61 and its second end 62. In the functional position, the first frame member 6 is oriented parallel to the vertical direction Z. In the non-functional position, the first frame member 6 is aligned parallel to the longitudinal direction X.

[0033] The second frame member 7 is oriented essentially parallel to the longitudinal direction X in both the functional and non-functional positions. The second frame member 7 is located between a first end 71 and a second end 72 ( Fig. 3) longitudinally extended. The second articulation axis G2 is located in the region of the first end 71 of the second frame member 7. In other words, the first end 71 and the second end 62 are connected to each other in a relatively movable manner about the second articulation axis G2.

[0034] The second end 72 of the second frame member 7 is detachably rigidly connected to a first connecting section 21 of the base frame 2 in the functional position. In the non-functional position, the second end 72 of the second frame member 7 is detachably rigidly connected to a second connecting section 22 of the base frame 2. The first connecting section 21 is located at a front end region of the base frame 2 with respect to the longitudinal direction X. The second connecting section 22 is set back from the front end of the base frame 2 towards an unspecified rear end. The second connecting section 22 is positioned closer to the first pivot axis G1 with respect to the longitudinal direction X than the first connecting section 21.

[0035] For the detachable connection with the two connecting sections 21, 22, the hinged frame 3 has at least one connecting element which can be detachably connected to the respective connecting section.

[0036] In the illustrated embodiment, the folding frame 3 has two connecting bolts 721, 722 arranged transversely spaced apart from each other. The connecting bolts 721, 722 are arranged at the second end 72 of the second frame member 7 and can also be referred to as the first connecting bolt 721 and the second connecting bolt 722. The connecting bolts 721, 722 are spring-loaded in opposite directions outwards with respect to the vertical central longitudinal plane in the transverse direction Y.

[0037] The connecting sections 21, 22 have bolt receptacles 211, 212, 221, 222 arranged opposite each other in the transverse direction Y. The bolt receptacles 211, 212, 221, 222 are designed to receive the connecting bolts 721, 722. The bolt receptacles 211, 221 can each also be referred to as the first bolt receptacle. The bolt receptacles 212, 222 can each also be referred to as the second bolt receptacle.

[0038] In the operating position, the connecting bolts 721, 722 are detachably locked into the bolt receptacles 211, 212 of the first connecting section 21. Specifically, the first connecting bolt 721 engages in the first bolt receptacle 211, and the second connecting bolt 722 engages in the second bolt receptacle 212. In the non-operating position, the connecting bolts 721, 722 are detachably locked into the bolt receptacles 221, 222 of the second connecting section 22. Specifically, the first connecting bolt 721 engages in the first bolt receptacle 221, and the second connecting bolt 722 engages in the second bolt receptacle 222.

[0039] It is understood that, notwithstanding the present embodiment, the second end 72 of the second frame member 7 can be detachably connected to the base frame in various ways. In this respect, the bolted connection shown here between the connecting bolts and the bolt receptacles is to be understood as purely exemplary.

[0040] Furthermore, the second end 72 does not necessarily have to be connected to the base frame 2 in the non-use position.

[0041] To lock the aforementioned bolted connection, a locking device 8 with a rotary handle 81 is provided. The locking device 8 is located in the region of the second end 72 of the second frame member 7 and acts on the two connecting bolts 721, 722 in a manner not shown in detail. By manually turning the rotary handle 81, the connecting bolts 721, 722 can be displaced inwards and / or outwards in the transverse direction Y. This allows the connection of the second end 72 to the respective connecting section 21, 22 to be locked and / or released. However, such a locking mechanism is not mandatory and is therefore not present in all embodiments.

[0042] In the illustrated embodiment, the second frame member 7 has a first frame section 73 and a second frame section 74, wherein the two frame sections 73, 74 are oriented at an angle to each other. In other words, the second frame member 7 is angled, curved, and / or cranked. The first frame section 73 has the first frame end 71 at one end and is connected to the second frame section 74 at the other. The second frame section 74 is connected to the first frame section 73 at one end, as already explained, and has the second end 72 at the other. In the functional position, the first frame section 73 extends longitudinally parallel to the longitudinal direction X and is thus oriented orthogonally to the first frame member 6. In this embodiment, the two clamping devices 5, 5' engage the first frame section 73.In its functional position, the second frame section 74 is inclined forward in the longitudinal direction X and downward in the vertical direction Z relative to the first frame section 73. In its non-functional position, the two frame sections 73 and 74 are essentially aligned along the longitudinal direction X. Fig. 4).

[0043] According to the invention, the folding frame 3 also has a third frame member 9. The third frame member 9 is pivotally mounted on the base frame 2 at one end, has a handle section 91 at the other end, and is also pivotally connected to the second frame member 7. The third frame member 9 is pivotally mounted on the base frame 2 at one end about a third pivot axis G3. The third pivot axis G3 is oriented parallel to the transverse direction Y and thus also to the first pivot axis G1 and the second pivot axis G2. The third frame member 9 and the second frame member 7 are pivotally connected to each other about a fourth pivot axis G4. The fourth pivot axis G4 is oriented parallel to the third pivot axis G3. Regarding the orientation of the fourth pivot axis G4 with respect to the transverse direction Y and the other pivot axes G1 and G2, the same applies analogously as already stated for the third pivot axis G3.

[0044] In the illustrated embodiment, the third frame member 9 extends between a first end 92 and a second end 93. The third pivot axis G3 is located in the region of the first end 92. The handle section 91 is located in the region of the second end 93. The fourth pivot axis G3 is located between the first end 92 and the second end 93 with respect to the longitudinal extent of the third frame member 9.

[0045] The third frame member 9 is assembled from several frame sections 94, 95, 96. The two frame sections 94, 95 can also be referred to as longitudinal sections. The frame section 96 can also be referred to as a transverse section and connects the two longitudinal sections 94, 95 to each other in the transverse direction. The latter are spaced apart from each other with respect to the transverse direction Y.

[0046] Furthermore, the second frame member 7 is fork-shaped in the area of ​​the fourth pivot axis G4. This fork shape is formed by two fork sections 741, 742 of the second frame section 74. The fork sections 741, 742 are spaced apart from each other in the transverse direction Y. The third frame member 9, more precisely its longitudinal sections 94, 95, engage transversely between the two fork sections 741, 742.

[0047] The handle section 91 is designed to grip the front and / or rear wheel of bicycle F. In the following Fig. In the configuration shown in Figure 1, the handle section 91 engages the rear wheel of bicycle F. The handle section 91 can be used to stabilize bicycle F for further fastening using the clamping device 5, thus eliminating the need to hold bicycle F manually in the interim.

[0048] In the embodiment shown, the third frame member 9 also has a further grip section 91'. This is assigned to the second receiving track S2 and is arranged at the other end of the transverse section 96.

[0049] In the functional position, the third frame member 9 projects upwards in the vertical direction Z and forwards in the longitudinal direction X from the base frame 2, starting from the third pivot axis G3. In the non-functional position, the third frame member 9 is essentially oriented in the longitudinal direction X and pivoted compactly against the base frame 2.

[0050] Starting from the functional position, the folding frame 3 can be moved into the non-use position as follows: First, the rotary handle 81 of the locking device 8 is manually gripped and turned. This releases and / or causes axial movement of the connecting bolts 721, 722. The connecting bolts 721, 722 then disengage from the bolt receptacles 211, 212 of the first connecting section 21. The second end 72 of the second frame member 7 is then detached from the base frame. In this detached state, the folding frame 3 can be folded by operating the rotary handle 8. Of course, an operator can also grip the folding frame 3 at a different point for this purpose. During folding, the first frame member 6 – in relation to the line of sight of the Fig.Frame members 1 to 7 pivot clockwise around the first pivot axis G1 towards the base frame 2. Simultaneously, the second frame member 7 folds counterclockwise around the second pivot axis G2 towards the first frame member 6. As a result of the connection with the second frame member 7, the third frame member 9 is also moved along with it, pivoting clockwise around the third pivot axis G3 relative to the base frame 2. Furthermore, the second frame member 7 and the third frame member 9 move relative to each other around the fourth pivot axis G4. Once the folded, unused position is reached, the folding frame 3 can be locked to the base frame 2 at the second end 72. This locking is achieved by means of the locking device 8 and the aforementioned bolt connection between the connecting bolts 721, 722 and the bolt receptacles 221, 222 of the second connecting section 22.

[0051] The first pivot axis G1 and the third pivot axis G3 are fixed in position relative to the base frame 2. The second pivot axis G2 and the fourth pivot axis G4 are movable relative to the base frame 2. When the folding frame 3 is opened and closed, the second pivot axis G2 moves along an arc around the first pivot axis G1. The same applies analogously to the movement of the fourth pivot axis G4, which moves along an arc around the third pivot axis G3.
