[0102] When describing the following figures, for reference numbers that are not explicitly explained in a figure, reference is made to the other figures.
[0103] FIGS. 1A, 1B, and 1C show a movement-tolerant wiring arrangement 10 including a mounting apparatus 20 comprising three segments 21 or segment portions 22 mounted in between. The segments 21 are respectively plugged into one another in the coupling portions 26. The mounting apparatus 20 is connected at both free ends with a fastening apparatus by using coupling parts 27, respectively. The respective segment 21 comprises an access or longitudinal slot 21.1 at a radially external side portion.
[0104] In FIGS. 2A, 2B, 2C, and 2D details of the respective segment portions 22 are shown. The segment portion 22 is formed of two halves, from which a lower half 22.1 is shown in FIG. 2A. Each half consists of a plurality of whirls or elements 23, which are linked to each other and are movable relative to one another by means of link sections 24. Preferably elements/whirls 23 have a cross-sectional profile having three side portions 23.1. Here the half 22.1 is formed integrally. Advantageously the elements/whirls 22 comprise an U-shaped cross-sectional profile including at least one lateral portion 23.1a axially protruding on at least one or both free ends of the U-shaped profile. The connection portions 24 are arranged approximately in the middle relative to a radial extension of the respective elements. The connection portions 24 are elastically deformable. To this end the connection portions 24 may be formed of a material with an especially high flexibility, and/or only a small width so that even relatively stiff materials are elastically deformable. A respective connection portion 24 is preferably formed by a small fillet that is made of the same material as further portions of the segment portion 22. Two adjacent elements 23 are connected by using two fillets/connection portions 24, respectively, in particular, at an upper side and at a lower side of segment 21. This can ensure that the segment 21R or the fastening apparatus 20 will not be twisted or bent by torsion. The connection portions 24 are arranged along a common longitudinal axis and constitute a kind of continuous backbone, this is a kind of backbone that is comparably stiff in structure, of the mounting apparatus 20. However, at an outer side or inner side no fillets are provided to allow for a maximum movement tolerance. In other words, each element 23 is arranged approximately parallel to the axis of rotation in a pivotable way.
[0105] At the inside and outside of the connection portions 24 recesses 25 are formed. The dimensions of the recesses 25 may define the amount of movement allowed. The recesses 25 ensure that the elements 23 allow for a high degree of freedom of movement relative to one another. Thus, the elements 23 may be arranged relative to one another about an axis of rotation in a way resulting in an optionally smaller or larger curvature radius of the segment 21. Each element 23 comprises three side portions 23.1 which enclose a line duct KL and extend at least approximately in a plane, respectively, with one of the side portions being a lateral section 23.1a arranged radially on the outside, limiting the line duct KL radially on the outside.
[0106] FIG. 2a shows that the halves 22.1, 22.2 comprise a coupling portion 22.1a, 22.2a, respectively, where the other half 22.1, 22.2 is connectable with the half 22.1, 22.2. The coupling portions 22.1a, 22.2a are thus formed by a single element 23, that is, by pins 23.2 on the one hand, and by pin retainers 23.3 on the other hand, each comprising engagement means 23.2a, 23.3a, respectively. The coupling portions 22.1a, 22.2a are provided at an inner side of the mounting apparatus 20. The pins 23.2 and pin retainers 23.3 are alternately arranged in series at the periphery. Thus, a resilient, robust plug connection may be provided by means of the coupling portion 22.1a. The respective halves 22.1, 22.2 may also be configured as identical parts.
[0107] In FIG. 2a is further shown that the half 22.1 comprises a coupling portion 26 at both free ends. A first coupling portion 26.1 is formed at the first free end, and a second coupling portion 26.2 is formed at the second free end. Both couplings portions 26.1, 26.2 are formed complementary to one other or in a geometrically corresponding way, so that the first coupling portion 26.1 of a first segment portion 22 may be plugged into a second coupling portion 26.2 of a second segment portion 22.2. Adjacent to the first coupling portion 26.1 a pin 23.2 is arranged, and a pin retainer 23.3 is arranged adjacent to the second coupling portion 26.2. In this configuration the halves 21.1, 22.2 can be used easily as identical parts for a modular configuration of the fastening apparatus 20. The respective coupling portion 26 may alternatively form a coupling part 27 to connect to the fastening apparatus.
[0108] In FIG. 2B the structure of one single element 23 of one of the halves 22.1, 22.2 is shown in detail. The coupling portions 22.1a, 22.2a are formed by pins 23.2 having a T-shaped cross-sectional profile and pin retainers 23.3 each including a retainer cavity with a respective geometrically corresponding cross-sectional profile. The pins 23.2 and pin retainers 23.3 are arranged at the inner side portion 23.1, respectively. The pins 23.2 comprise engagement means 23.2a being adapted as engagement hooks, respectively, which may be elastically biased, and the pin retainers 23.3 comprise engagement means 23.3a being adapted as steps or undercuts, respectively, provided in a geometrically corresponding way to the engagement hooks. An abutment edge 21.1a at the lateral portion 23.1a allows for the isolation of an access or longitudinal slot formed between two halves.
[0109] FIG. 2C shows how the two halves 22.1, 22.2 are pluggable into one another. The shown segment 21 of the mounting apparatus 20 extends along a longitudinal axis L and is arranged helically. The mounting apparatus or respective segment 21 has an (outer) diameter dk20 that is variable and may be at least as large as the diameter of an annular cavity within which a relative movement of the mounting apparatus may be/is to be performed. The coupling part 27 provided on at least one free end of the segment portion 22 comprises first engagement means 27.1 adapted as engagement hooks which may be elastically biased, as well as second engagement means 27.2 adapted as steps or undercuts that are configured in a geometrically corresponding way to the respective engagement hooks.
[0110] FIG. 2D shows how the halves 22.1 of adjacent segment portions are pluggable into one another.
[0111] FIG. 3 shows an upper part 32 of the fastening apparatus 30 that is attachable to one of the connection components (not shown), in particular, to the socket (see FIG. 9A) by using a fastening section 31 comprising fastening means 31.1, in particular, through-bores. For example, screws can be used to screw the fastening apparatus 30 to the socket.
[0112] The upper part 32 comprises a latch 36 protruding in a peripheral direction that includes an abutment surface 36.1 that is curved inwards in the direction of the rotational axis. The mounting apparatus 20 may abut abutment surface 36.1, in particular, at one of the inner side portions 23.1 of the segment 21 mounted to the fastening apparatus 30. The latch 36 includes a curvature radius R36 that defines a minimum curvature radius of the mounting apparatus 20. This ensures that no excessive stress is applied on the plug connection between the mounting apparatus 20 and the fastening apparatus 30 and that the mounting apparatus 20 will be bent only to a certain degree. The upper part 32 and the lower part 34 shown in FIG. 4 constitute the fastening apparatus 30.
[0113] FIG. 4 shows a lower part 34 of the fastening apparatus that constitutes the latch 36 together with the upper part 32. The upper part 32 and the lower part 34 are pluggable into one another by means of a plug connection 35 comprising pin recesses 35.1 at the upper part 32 and pins 35.2 at the lower part 34.
[0114] FIGS. 3 and 4 show that the coupling part 37 comprises first engagement means 37.1 adapted as engagement hooks that may be elastically biased, as well as second engagement means 37.2 adapted as steps or undercuts that are formed in a geometrically corresponding way to the respective engagement hooks and steps in the segment portions.
[0115] FIG. 5 shows a further fastening apparatus 40 adapted for mounting in a rotationally locked way to the further connection component (not shown), in particular, at the spindle (see FIG. 9A). The further fastening apparatus 40 can provide a junction with a predefined curvature radius between the mounting apparatus 20 and the spindle. The rotational lock configuration/arrangement may be ensured by means of taps and springs 44.1 that engage with a corresponding groove at the connection component. As opposed to the fastening apparatus 30, it is not intended to fasten the connection component in a predefined relative position. The fastening apparatus 40 comprises a lower part 44 and an upper part 42 (see FIG. 6). The lower part 44 is formed as helical annular disk and expands about at least approximately 360°, which equals one winding. The lower part 44 comprises a support surface 44.3, on which the segment may rest. The support surface 44.3 extends in a radial direction over a width rK that is larger than the radial width of the mounting apparatus 20. The width rK defines the dimension of an annular cavity, within which the mounting apparatus 20 is able to perform a relative movement in a radial direction. The support surface 44.3 preferably forms a sliding pair with the mounting apparatus 20 or at least comprises a low friction coefficient or is adapted as a sliding support surface. The support surface 44.3 may, for example, be made of polyamide.
[0116] The lower part 44 includes a passage 44.4 extending radially inwards that passes through a wall 44.5. The passage 44.4 is a recess formed in wall 44.5. Lines can be routed through the passage 44.4 to a spindle.
[0117] FIG. 6 shows the upper part of the first fastening apparatus 40 that forms an interface (coupling part 47) to the mounting apparatus 20 together with the lower part 44. The upper part 42 and the lower part 44 are pluggable into one another by means of a plug connection 45 comprising pin retainers 45.1 at the lower part 44 and pins 45.2 (shown as dashed lines) at the upper part 42. The upper part 42 includes a plane upper surface 42.1 where a segment may rest upon. The upper side 42.1 is arrangeable at least approximately in the same plane as the support surface 44.3. The upper part 42 includes a leading-edge 42.2, 44.2 like the lower part 44, by means of which an insert 50 (see FIG. 7) may be coupled to the fastening apparatus 40.
[0118] The upper part 42 and the lower part 44 may be plugged into another by means of a plug connection 45 comprising pin retainers 45.1 at the upper part 42 and pins 45.2 at the lower part 44. In addition, the position of the parts 42, 44 relative to one another may be fixed, in particular, by using screws, by means of a securing portion 41 including securing means 41.1, in particular, (threaded) through-bores.
[0119] FIGS. 5 and 6 show that the coupling part 47 comprises first engagement means 47.1 adapted as engagement hooks, which may be elastically biased, as well as second engagement means 47.2 adapted as steps or undercuts that are formed in a geometrically corresponding way to the respective engagement hooks and steps in the segment portions.
[0120] FIG. 7 shows an insert 50 adapted as cover or lid for covering routed lines. The insert 50 comprises two guiding profiles 50.2 adapted in a geometrically corresponding way to the leading edges 42.2, 44.2. The insert 50 comprises a plane upper side 52 which lies at least approximately in the same plane as the support surface 44.3 or the upper side 42.1. In addition, the insert 50 includes engagement hooks 51 that are adapted to fix the insert 50 to the mounting apparatus 40, and which are adapted in a geometrically corresponding way to the respective engagement means of the mounting apparatus 40. The insert 50 further includes a radial partition 53 that is arranged radially outside, by means of which a line duct KL being formed by the fastening apparatus 40 may be isolated. The insert 50 is preferably mounted after the routing of lines. Due to the insert 50 the further fastening apparatus 40 or the mounting apparatus 20 remain easily accessible. The insert 50 includes a bracket 54 protruding radially inwards that may engage with the passage of the spindle and guide the line(s) through the passage, for example, in particular, without the risk of damaging the lines in the passage.
[0121] In many applications the lines are routed preferably upwards within the spindle, in particular, for ceiling stands. The bracket 54 may thus create a security space between the line portions routed in the spindle and further windings of the mounting apparatus. On the bracket an elevation may be provided/formed that has the external radius of the spindle and thus replicates the shape of the spindle. Thereby an interlocking of the mounting apparatus at the passage or the spindle window 3.2 can be prevented.
[0122] FIGS. 8A and 8B show the further fastening apparatus 40 in an assembled state including the insert 50. To enable a simple exchange of systems components, the disc-like fastening apparatus 40 is formed of multiple parts. Together with the insert 50, the fastening apparatus 40 may form a line duct KL to define a routing path of line(s), as can be seen in FIG. 9A. The fastening apparatus 40 comprises a diameter dK defining a diameter of the annular cavity K (see FIG. 11), within which the mounting apparatus may/is to perform a relative movement. The inner radius of the line duct KL may be about 50 mm, for example, the outer radius about 40 mm, for example, and a deflection angle about 90°, for example.
[0123] FIG. 9A shows a connection component adapted as a socket 4, where the fastening apparatus 30 of the wiring arrangement 10 is fastened in a fastening portion 4.1. The socket 4 is rotatably mounted to a hollow spindle 3, shown in FIG. 9B, that defines an axis of rotation D. Here the socket 4 is part of a rotary joint 7 or forms said rotary joint 7, in particular, together with the spindle 3. To this end the socket 4 may include at least one bearing, for example, a ball bearing. The socket 4 is connected with a carrier arm 5 in a non-rotatable manner. The fastening apparatus 30 includes a cable duct 5.1 of the carrier arm, in which one or more lines may be routed. In a lower area of the wiring arrangement 10 the line duct KL that is formed by the further fastening apparatus 40 is displayed.
[0124] In FIG. 9B a line 70 is indicated that is routed in the cable duct 5.1 and guided through the fastening apparatus 30 to the mounting apparatus 20. Thus, the lines from a lower end of the mounting apparatus, that means starting at the further fastening apparatus 40, may be routed through a passage 3.2 and within the spindle 3 upwards or downwards, in particular, to a ceiling flange. As described above, the fastening apparatus 30 is fastened to the socket 4 and the spindle 3 in a rotationally locked manner by spring(s) 44.1 engaging with groove(s) 3.1. When the carrier arm 5 is pivoted relative to the spindle 3, the rotational position of the fastening portion 4.1 is displaced relative to the further fastening apparatus 40. Here the mounting apparatus 20 will be compressed or expanded, and thus its curvature radius is enlarged or reduced. The mounting apparatus 20 expands itself radially or contracts itself radially. For this end, the mounting apparatus has a predefined movement area K, in particular, an annular cavity formed between the external lateral surface of the spindle 3 and an interior lateral surface of the socket 4 or an insert (see FIG. 10A, 10B).
[0125] FIG. 10A, 10B show an insert 60 adapted as tray or radial partition that is arrangeable between an inner side of the socket and the mounting apparatus. The height of the insert 60 equals at least approximately the height of the socket. Engagement hooks 61 are arranged on the upper side and lower side of the insert 60 which are configured to attach the insert to the socket in a form-fitting and/or force-fitting way (see FIG. 11). The insert 60 includes a planar inner surface 60.2 where a radial outer side of the mounting apparatus may abut. This ensures that the mounting apparatus will not interlock with any steps or protrusions of the socket, regardless of the configuration of the socket. Instead the mounting apparatus may be guided at the inner surface 60.2 in an almost frictionless way. The inner surface 60.2 encloses the annular cavity K section-wise radially on the outside.
[0126] FIG. 11 shows the wiring arrangement 10 in a finally mounted state, wherein the lines guided by the wiring arrangement 10 are not shown.
[0127] The wiring arrangement 10 described above enables the simple routing of lines and an adequate arrangement of lines about an axis of rotation in a way that a relative rotation of two connection components may be performed without the risk of jamming or interlocking the lines, in particular, also with large relative rotational angles of more than 360°. The mounting apparatus 20 of the wiring arrangement 10 is thus displaceable in a radial direction in an annular cavity and variable in its curvature radius, that means expandable/enlargeable or reduceable.
[0128] FIG. 12 shows that between the inlay 60 or single inlay trays and an external lateral surface 3.3 of the spindle 3 an annular cavity K is defined that is bounded by the support surface 42.1, 44.3; 52 of the lower fastening apparatus 40 or insert in the lower direction. On the one hand, the mounting apparatus 20 is capable to perform a sliding relative movement in a radial direction and a peripheral direction on the support surface 42.1, 44.3; 52 relative to the support surface 42.1, 44.2; 52, and on the other hand, a sliding relative movement in axial direction and peripheral direction along the inner surface 60.2 of the inlay.
[0129] A line may be routed/guided starting at the carrier arm 5 through the mounting apparatus 20 and be guided in the area of the first (lower) fastening apparatus inwards through the passage 3.2 into the cylindrical cavity of the hollow spindle 3, wherein the radially inward protruding racket 54 may prevent a chafing with the edges of the passage 3.2.
[0130] FIG. 13 shows that due to the wiring arrangement 10 described above a cladding 6 of a stand device 1 or carrier arm 5 may be provided in a way that no lines are visible or may jammed. The wiring arrangement 10 may be enclosed completely by the cladding 6 and thus may be integrated in a carrier arm 5 or a rotary joint between two carrier arms.
[0131] FIG. 14 shows a socket 104 that includes a fastening portion 104.1 adapted as a rib. The rib protrudes axially from a plane lower side of the upper annular portion of the socket 104. The rib 104.1 extends at least approximately radially or parallel to a radial direction, depending on the preferred position of the rib. The rib includes at least one bore or at least one opening 104.1a, where a fastening apparatus of a wiring arrangement according to the invention may be fastened. In addition, the rib comprises an abutting face 104.1b formed in a geometrically corresponding way to the respective abutment face of the fastening apparatus. Preferably, the abutting face extends at least approximately in a radial direction or parallel to a radial direction. The abutting face may also be described as radial flank.
[0132] The rib 104.1 enables or facilitates a (de)assembly of the wiring arrangement even in cases where the stand device has already been assembled or has been at least partly put in operation.
[0133] FIG. 15 shows the wiring arrangement 10 according to the invention including the components mounting apparatus 20, fastening apparatus 130, and further mounting apparatus 140. The mounting apparatus 130 includes a fastening portion 131 including an abutting face 131a and fastening means, in particular, bores 131.1. The abutting face 131a is formed in a geometrically corresponding way to the respective abutting face 104.1b of the socket. An upper fastening part 132 comprises a hook 132.1 configured for mounting to the socket. The hook 132.1 is formed in a geometrically corresponding way to a respective portion of the socket. The hook is preferably configured to enclose an outer rim or edge of a peripheral contour of the socket at least in a form-fitting way. By means of the hook 132.1, the fastening apparatus 130 may be fixed to the socket, even if the fastening apparatus 130 has not yet been fastened to the fastening portion. Thus, last but not least, the hook 132.1 facilitates assembly. The hook 132.1 can also facilitate a positioning of the fastening apparatus 132, for example, to fix the fastening apparatus 130 to the fastening portion 104.1. The hook 132.1 may also be formed as a clamp or as U-shaped profile, for example.
[0134] The further fastening apparatus 140 may be partitioned at a coupling 148 which improves mounting or facilitates any exchange at the site.
[0135] FIG. 16 shows first and second parts 144a, 144b of a lower fixing part 144 of the further fastening apparatus 140. The coupling 148 is formed between the two parts 144a, 144b as a plug coupling. The coupling 148 extends radially along the complete width of an annular portion of the lower fixing part 144 and partitions the lower fixing part 144 in two parts that extend over a pitch circle or along an arc of at least about 180°, respectively. Said partitioning in two halves allows for a simple (de)assembly and a good access independent of the relative rotational position of said lower fixing part 144 relative to the socket.
