Description

The invention relates to a protection and guiding device for cables or hoses.

For the sake of simplicity, in the following reference is made to cables or the like only as cables, although other flexible elements, such as in particular hoses, can also be accommodated in the protective and guiding device instead of cables. In particular, one or more cables, such as power or fiber optic cables, and / or one or more pipes or hoses, such as pneumatics or hydraulic hoses, are accommodated in such a protection and guide device, which, starting from a stationary part, is a movable part of a machine tool or a Supply other machines with electrical energy, supply energy in the form of compressed air or serve for signal transmission. The protection and guiding device guides and protects the cable safely and reliably while the moving part is moving. The protection and guiding device is sometimes also referred to as a guiding chain due to its design and function. The protection and guiding device can be used, for example, in a machine tool, a conveyor device, a construction machine, a semiconductor device, a pharmaceutical sample storage device, a vehicle door opening / closing device or the like. In particular, the protection and guiding device for cables assumes a linear, extended position or a curved position in accordance with the relative movement between the movable part and the stationary part.

From the Japanese patent application JP 2008-190 684 A and in use there is known a cable protection and guiding device 500 as shown in FIG 18th is shown wherein a plurality of pairs of spaced apart right and left side panel portions 510 are connected to one another from a fixed mounting end to a movable mounting end. Connecting webs 540 are respectively arranged in a bridging manner on the side of the side plate regions 510 arranged on the outside during bending and on the side arranged on the inside during bending at predetermined intervals. A cable is received in a cable receiving space formed by the side plate regions 510 and the connecting webs 540 and extending from the fixed mounting end to the movable mounting end. The side plate portion 510 includes a link unit 520 having a predetermined number of integrally molded side plates 522 connected by connecting portions 524 and stopper members 530.

In this protection and guiding device 500, the link units 520 are designed in the manner described below. As in 19th As shown, a connecting hook 527 is formed at one end of the link unit 520 and has an external shape similar to the shape of a connecting portion 524. This connecting hook 527 has an arcuate cutout portion 527c at a side end portion. The portion extending from a cable receiving room-side connecting arm 526 is formed as an arcuate convex portion (not shown) having the same shape as a member formed on a cable receiving room side of the connecting portion 524.

A connecting plate 528 is formed at the other end region of the link unit 520. Further, an arcuate convex portion 528c is formed on the outer side surface of this connecting plate 528 and a portion extending from the connecting arm 526, which protrudes into the arcuate cutout portion 527c formed on the connecting hook 527. Furthermore, on a surface of the connecting plate 528 on the side of the cable receiving space and at a position which is arranged as a mirror image of a position at which the arcuate convex region 528c is arranged with respect to the connecting plate 528, an arcuate convex region 528d is formed, which has the same shape, like the arcuate convex portion 528c as shown in FIG 18th evident.

The connecting hook 527 and the connecting plate 528 are connected to each other in such a way that the arcuate cutout portion 527c of the connecting hook 527 and the arcuate convex portion 528c of the connecting plate 528 abut each other (see FIG 19th ). An upper convex portion 527a provided on an upper portion of the connecting hook 527 and an upper concave portion 531 provided on a connecting portion of the lower supporting portion 534 of the stopper member 530 are engaged with each other, thereby forming a clip connection. Two link units 520 are connected to one another. Then, a back surface of the connecting hook 527, which includes an arcuate convex portion extending from the cable receiving space side of the connecting arm 526, engages with an arcuate cutout portion 528e formed on a side end portion of the connecting plate 528 and on an arc portion 539 of the stopper member 530 .

From the DE 10 2007 061 296 A1 is known a protection and guiding device for cables or the like, comprising a number of pairs of right and left, spaced apart side plate portions, which are connected to one another from a stationary mounting end to a movable mounting end, connecting arms, the are respectively arranged bridging on the side arranged inside during bending and the side arranged outside during bending at predetermined intervals, so that the side plate regions and the connecting arms form a cable receiving space. A plurality of side plate areas are cast in one piece and form a module member. The module member has connection areas which connect the side plate areas to one another.

Such a protection and guiding device for cables still leaves something to be desired, in particular with regard to the attachment of the device to a machine or the like.

The invention is based on the object of improving a protective and guiding device of this type for cables, it being particularly intended that the length of the device can be determined in a simple manner. In addition, the strength of the areas in which the link units are connected to one another should be increased. Furthermore, the assembly is to be simplified and a possibility for attaching mounting brackets to the ends is to be provided in order to attach the protective and guiding device as easily as possible to a stationary part and a movable part of a machine or the like.

This object is achieved by a protective and guiding device for cables or hoses with the features of claim 1. Advantageous configurations are the subject of the subclaims.

According to the invention, a protection and guiding device for cables or hoses is provided, comprising a plurality of left and right link units which form spaced apart left and right side plate regions and are connected to one another in the longitudinal direction between a fixed mounting end and a movable mounting end. Connecting webs are each arranged in a bridging manner on the side of the side plate regions arranged on the inside during bending and on the side of the side plate regions arranged on the outside during bending at predetermined intervals. A cable or hose can be received in a cable receiving space which is formed by the side plate areas and the connecting webs and extends from the fixed mounting end to the movable mounting end. The link units comprise side panels and / or areas of side panels which are cast in one piece and connected to one another by means of a predetermined number of connection areas. Flexible connecting arms extend from the connecting areas, connecting the side panels or areas of side panels to the connecting areas. Stopper members are connected from the cable receiving space side in engagement between two adjacent side plates or between a side plate and a region of side plates or between two adjacent regions of side plates and with the connecting region arranged therebetween by means of a clip mechanism. The link units have a connecting plate with a protruding element and a connecting plate with a recessed element, which are respectively connected to the other longitudinally adjacent link units. The connecting plates cooperate with the other connecting plates of the adjacent link units. The protruding link plate and the recessed link plate are each formed with the same external shape as the side plates when connected to a recessed link plate and a protruded link plate of an adjacent link unit, respectively. It should be noted that in the present case link units without side plates can also be provided, which form the side plate areas. In this case, link units are provided with two connecting plates and a connecting area arranged therebetween, which is connected to the connecting plates via connecting arms. Here, the connecting areas between the individual link units, ie the areas where the connecting plates are connected to one another, are in different places than in the 18th and 19th shown, known protection and guiding device is provided, namely at other points than the contact areas between the connecting areas arranged between the connecting arms and the stopper members attached thereto. Thus, the connection strength is increased. In addition, since the wall thickness of the connecting plates with a protruding member and the connecting plates with a recessed member can be made equal to the wall thickness of the side plate, the strength of the individual link member portions can be increased. In addition, a link-clamp adapter is provided in the device according to the invention, in which a connection plate with a protruding element or a connection plate with a recessed element is provided at the first end and a connection area is provided at the second end. This link-clamp adapter can be connected to a link unit. The link-bracket adapter may have any number of side plates and connection areas, the number and hence the length of the link-bracket adapter being determined by cutting off a link arm of a link unit at the desired position. Mounting brackets are provided at the ends of the device formed by the link-bracket adapters, namely at the later stationary mounting end to a movable mounting end. The mounting brackets are each in engagement with the connection area, which is provided at the end of the link-bracket adapter. Here, the connection area and the mounting bracket are connected to one another by means of a clip mechanism. By providing a clip mechanism for connecting the connecting area and the mounting bracket, which corresponds to the clip mechanism between the stopper member and link unit or stopper member and link-bracket adapter, assembly can be simplified.

It should be noted here that “any number of side panels” also means that no side panel is provided, ie in the case of a link-bracket adapter, it consists of a connecting plate (also referred to as the area of a side plate), a connecting arm and a connecting area exists, wherein the second connecting arm, which starts from the connecting area, is cut off, so that the shortest possible length for a link-clamp adapter results.

The connecting plate with protruding element and the connecting plate with recessed element of adjacent link units as well as mutually adjacent link units and link-bracket adapters each have a convex, i.e. protruding area and a concave, i.e. recessed area in the central area of their end faces. The connecting plates are connected to one another by means of a twist-and-snap mechanism in which the two connecting plates are connected by engaging the protruding area in the recessed area and then rotating the connecting plates in opposite directions. Due to the prepositioning and subsequent rotation that takes place first, the connection of two link units can take place in a simple manner, in particular before the attachment of the stopper links including the connecting arms. Furthermore, in the event of damage, a link unit or a link-clamp adapter can simply be replaced; in particular, a link unit with a plurality of side plates can also be supplemented to the length of the original link unit by combining a plurality of short link units without side plates or with fewer side plates just replace. It is therefore not necessary to keep different link units in stock, since any length can be combined. Furthermore, even in the case of finished chains, the length can be changed easily and in relatively small length increments given by the length of a link unit without side plates by replacing individual, long link units with shorter ones or adding new link units. Storage is also simplified by the fact that link-clamp adapters can simply be produced from the link units, for which purpose they only have to be cut off in a suitable position next to a connection area.

It is particularly preferred that the connection direction, i.e. the rotary movement, does not lie in the working direction of the device, i.e. the bending direction, so that the link units can be securely connected and the forces during operation do not load the connection areas of the link units or only load them slightly. Furthermore, the locking areas which are arranged in the upper and lower areas around the protruding area and the recessed area, respectively, make it possible to achieve good durability of the device.

In the device according to the invention, a first connecting web is preferably cast in one piece on the side of a pair of right and left stopper members arranged on the inside during bending, and a second connecting web is preferably with first and second ends, the bridging on the right-hand side of the pair arranged on the outside during bending and left stopper members, the second connecting web having said first end flexible and integrally molded with one of the pair of right and left stopper members, and said second end releasably attached to the other of the pair of right and left stopper members, so that the second connecting web is an openable / closable connecting arm. This results in a one-piece, cast design of the pairs of stopper members with the two connecting webs.

Overall, the protection and guiding device for cables can reduce the number of parts that are required for this. The assembly can also be simplified. This also enables a reduction in possible assembly errors.

Materials that are suitable for the link unit, the stopper link, the connecting webs and the like, which are used in the protective and guiding device for cables according to the invention, are sufficiently strong, fatigue-resistant and impact-resistant materials, in particular engineering plastics such as polyamide 6, polyamide 12, Polyamide 46, polyamide 66, acrylic, polyacetal, and the like. These materials withstand the bending stresses that occur during bending, and the device exhibits excellent dimensional stability. In particular, when molding a synthetic resin fatigue-resistant material in which an elastomer or rubber component is contained in a polyamide resin or polybutylene terephthalate resin, the contained elastomer or rubber component provides improved flexibility and impact resistance. A fatigue-resistant synthetic resin material also shows Impact resistance and fatigue resistance, and it can withstand repeated bending without deformation. For this reason, fatigue-resistant materials with an elastomer or rubber component are preferably used.

In the following, with reference to an embodiment and the 1 until 15th a protection and guiding device 100 for cables according to the present invention. the 16 and 17th show a second embodiment of possible link units from which the protection and guiding device can be composed. The devices according to the two exemplary embodiments serve to protect and guide a power cable (not shown) of a machine tool, which is arranged between a stationary part (not shown) and a movable part (not shown), but can also be used for other purposes. Depending on the position of the movable part in relation to the stationary part, the devices can assume an extended or bent position.

Here, according to the first embodiment, there are a pair of spaced apart left and right side plate portions 110 with each other from a stationary mounting end, which is attached to the stationary part, to a movable mounting end, which is attached to the movable part, are provided, with fixed connecting webs 142 and openable / closable connecting bridges 144 each bridging on the side of the side plate areas which is arranged on the inside during bending and the side of the side plate areas which is arranged on the outside during bending 110 are arranged at predetermined intervals, and a cable (not shown) is accommodated in a cable accommodating space having a rectangular cross section from the stationary mounting end to the movable mounting end surrounded by the pair of left and right side plate portions 110 , fixed connecting webs 142 and openable / closable connecting webs 144 .

The side plate area 110 has limb units 120 with a predetermined number of side plates 122 on. The side panels 122 of the individual link units 120 are integrally connected to one another via diamond-shaped connecting areas 124 (please refer 1 ) and flexible connecting arms 126 that differ from these connection areas 124 extend out. There are also stopper members 130 as part of the side plate areas 110 intended. Each stopper link is here 130 with the two opposing and spaced apart side plate areas 110 from the cable receiving space side, and is engaged with the connecting portion 124 of the opposing link units 120 connected by means of a clip mechanism. In the present embodiment, a link unit 120 a side plate area 110 three full side panels 122 on.

Furthermore, as in 3 shown, said fixed connecting web 142 integral with a pair of right and left stopper links on the side that is inwardly disposed during bending 130 poured. One end of said openable / closable connecting web 144 is flexible and integral with one side of a pair of right and left stopper members on the side that is outwardly disposed when bending 130 cast, and the other end of the openable / closable connecting web 144 is detachable with the side of the pair of right and left stopper links that is on the outside when bending 130 connected. As a result, there are a pair of right and left stopper members 130 , a fixed connecting bridge 142 and an openable / closable connecting bridge 144 designed as a one-piece cast part, so that the number of parts and the control effort during assembly are reduced.

The following is a connection structure between the link units 120 and the stopper member 130 and their function explained in more detail.

As in 1 until 3 shown is the stopper member 130 into a connection area 124 the limb unit 120 installed from the cable receiving space side by means of a clip mechanism, whereby the bending angles are limited in both directions, ie both the maximum bending and the maximum stretching (or possibly also overstretching) are limited.

According to the present embodiment, there is an upper convex end region 124a at an upper end portion of the diamond-like connecting portion 124 provided, which in 6th is shown. This upper convex end area 124a is with an upper concave area 131 engaged on an upper portion of the stopper member 130 is provided, as in 4th shown. At the same time there is a lower concave end area 124b , the one at a lower end portion of the diamond-like connecting portion 124 is provided in engagement with a lower concave portion 132 attached to a lower portion of the stopper member 130 is provided so that a clip mechanism is formed. Furthermore, there is a cylindrical protruding area 124d slightly above the middle of the connection area 124 provided as in 6th shown in a circular indentation 136 is fitted, which is slightly above the center of the stopper link 130 is designed as in 4th shown so that the connection between the connection area 124 and the stopper member 130 is strengthened.

Upper convex side areas 137 of the stopper link 130 , shown in 4th , are on the back of a side panel 122 , shown in 6th , added, ie in the upper contact areas 122a that are at the upper right and left areas on the cable compartment side of the side panel 122 are trained. Correspondingly, there are lower convex side areas 138 of the stopper link 130 , shown in 4th , in lower contact areas 122b that are at lower right and left areas on the cable compartment side of the side panel 122 are designed as in 6th shown. An arcuate convex area 124c is on the cable compartment side of the connection area 124 trained as in 6th shown, and lies on an arcuate area 139 of the stopper link 130 on.

4th shows the stopper member 130 which is integral with an upper link support area 133 and a lower connection support area 134 is poured, which is the connection area 124 that is between the side panels 122 the limb unit 120 is trained to support. As in 2 shown, the upper link support area fits 133 between adjacent side panels 122 and the top of the connection area 124 is between adjacent side panels 122 educated. Such a structure is limited to the side of the protective and guiding device which is arranged on the outside during bending 100 for cables a bending, so that the side which is arranged on the outside during bending is not bent over an essentially straight line in the present case. It should be noted that an area denoted by the reference symbol 135 in 4th is characterized is a concave contact area with which the openable / closable end of the openable / closable connecting web 144 is in contact.

The lower connection support area 134 is at a lower portion of the connection area 124 at that between adjacent side plates 122 is trained. split S. are between the side panels 134a of the lower connection support area 134 and lower side surfaces 122c of the adjacent side plates 122 in 4th shown. As in 2 shown, lies a side plate 134a of the lower connection support area 134 on a lower side surface 122c the side plate 122 to the bending angle on the side of the protective and guiding device that is arranged on the inside during bending 100 for cable limit. That is why the link arm 126 does not impose excessive bending stress, so that the device has improved durability.

A link-clamp adapter, which is an essential part of the present invention, is explained in more detail below. The link-clamp adapter forms the connection between a link unit 120 and a mounting bracket 150A or. 150B . As in 3 shown in which the link-bracket adapter with the reference numerals 161 or. 162 these are link-bracket adapters 161 and 162 each between a link unit 120 and a mounting bracket 150A , 150B and arranged connected to the same, so that the exact length of the protection and guiding device 100 can be determined exactly. These link bracket adapters 161 and 162 can by cutting off a link unit 120 in the area of the corresponding connecting arm 126 be designed so that the link-bracket adapter has the required length. Any link-bracket adapter 161 , 162 has such a shape with a connecting area 124 at one end and a connecting plate 127 with a protruding element or a connecting plate 128 with a receding element at the other end. Here is a connecting arm 126 a link unit 120 , as in 5 shown at a position ( 161 ) cut off in such a way that one link of a link-bracket adapter 161 is designed as in 3 shown, and a connecting plate 127 with protruding element and a connecting area 124 includes. 7th Figure 3 is a perspective view of a link-bracket adapter 161 . The same way becomes a link arm 126 a link unit 120 , shown in 5 , at one position 163 cut through, making a three-pronged link-bracket adapter 163 , shown in 8th arises, which is a connecting plate 127 with protruding element and three connecting areas 124 as well as two side plates 122 includes. This link-bracket adapter 163 is at a position opposite the link-bracket adapter 162 , shown in 3 used, that is, the link-bracket adapter 163 and the link-bracket adapter 162 can be used as a pair.

As previously described, by cutting off a connecting arm 126 the limb unit 120 with the aid of a knife or the like, a link-clamp adapter can easily be formed at the appropriate position, which has a connection area at one end 124 which is built into a mounting bracket and has a connecting plate at the other end. The connection has a clip mechanism. The number of connection areas 124 is monitored in this way. At the other end is a connecting plate 128 with a recessed element or a connecting plate 127 formed with a protruding element, which with a connecting plate 127 with a protruding element or a connecting plate 128 with receding element of the adjacent link unit 120 connected. Further, since the link-bracket adapter has the same structure as the link units except that one end of the link-bracket adapter is through a connecting portion 124 is formed, the connection between the stopper member 130 and the link-bracket adapter in the same manner as between a link unit 120 and the stopper member 130 . Because of this, assembly is easy. Furthermore, in the present exemplary embodiment it is not necessary to provide an additional metal casting mold for the production of the link-clamp adapter.

A mounting bracket, which is also an essential part of the present invention, is described in more detail below. The mounting brackets are identified by the reference symbols 150A and 150B in the 1 and 3 referred to, wherein there is a stationary assembly end and a movable assembly end of the protection and guiding device 100 are. The mounting brackets 150A , 150B are each attached to a stationary part or a movable part of the machine tool. The mounting brackets 150A and 150B like them in the 1 and 3 are shown, are mirror images and are provided at the stationary mounting end and at the movable mounting end. A connection area 124 , which is provided at one end of the above-described link-bracket adapter, includes a clip mechanism and is attached to the mounting bracket.

9 Figure 13 shows an enlarged perspective view of a mounting bracket 140A. How out 9 you can see the mounting bracket 150A molded in one piece with one side of a stop member through a mounting area 151A is replaced. In the assembly area 151A is a through opening 152A for feeding through a fastening screw for fastening the mounting bracket 150A intended. An area of the mounting bracket 150A having the same shape as a stopper member is with a connecting portion 124 (please refer 7th and 8th ) connected, the connection area 124 occurs at one end of the link-bracket adapter and forms the same connection structure as that of the link unit described above 120 and the stopper member 130 . At the same time is the stopper link 130 in engagement with a connecting plate 127 with protruding element (cf. 7th ) or a side plate 122 (see. 8th ) associated with the connection area 124 connected is. It should be noted that in the case of a mounting bracket 150B with a mirror image of the mounting bracket 150A , a portion having the same shape as a stopper member of the mounting bracket 150B with a connection area 124 (not shown) is connected. At the same time, the portion having the same shape as a stopper member is engaged with a connecting plate 128 with a recessed element or a side plate 122 that go with the connection area 124 connected is. It should be noted that since the connection between the mounting bracket and the link-bracket adapter is the same as the connected structure between the above-mentioned link unit 120 and a stopper member 130 is referred to a detailed description of the areas that the stopper member 130 in 4th are omitted, the reference numerals from 130 in 4th in 9 are increased by 20 each.

The following is the connection mechanism between the link units 120 explained in more detail. A limb unit 120 has a connecting plate 127 with protruding element and a connecting plate 128 with receding element, each connected to a different link unit, as in 5 and 6th shown. When the connecting plate 127 with protruding element and the connecting plate 128 with a recessed element with a connecting plate 128 with recessed element or a connecting plate 127 with protruding element of the adjacent link units 120 connected, they have the same external shape as a normal side plate 122 , as in area A of 1 is shown. For this reason, the connecting plates are also referred to as "areas of side plates".

The connecting plate 127 with protruding element is at one end of the link unit 120 provided as in 10 shown. The external shape of the connecting plate 127 with protruding element is cut in a vertical center line and has a cylindrical protruding portion 127a roughly in the middle of their end face. An upper locking area 127b and a lower locking area 127c are integral at upper and lower positions that are point-symmetrical to the central axis of the cylindrical protruding area 127a are.

The connecting plate 128 with the receding element is at the other end of the link unit 120 provided as in 11 shown. The external shape of the connecting plate 128 The receding element is also cut in a vertical centerline and has a circular receding area 128a roughly in the middle of their end face. An upper locking area 128b and a lower locking area 128c are integral at upper and lower positions that are point-symmetrical to the central axis of the circular recessed area 128a are.

The locking areas 127b , 127c , 128b , 128c both connecting plates 127 and 128 are each designed corresponding to one another with a protruding, ie undercut, area formed by an undercut (see 12th ), in which an undercut area of the other connecting plate engages as a result of the rotary movement.

The connecting plate 127 with protruding element and the connecting plate 128 with recessed elements are connected to one another by means of a twist-snap connection mechanism. like in the 12th until 15th shown. First, as in 12th shown two link units 120 brought closer together, with the orientation of the connecting plates 127 and 128 is substantially perpendicular to the final alignment. Here are the connecting plates 127 and 128 arranged opposite one another. As in 13th shown are the above area 127a in the receding area 128a fitted. As in 14th both connecting plates are shown 127 and 128 in opposite directions using the fitted protruding area 127a in the receding area 128a rotated as the center so that a face of the connecting plate 127 with a protruding element and a surface of the connecting plate 128 with the receding element are in contact or almost in contact with one another. At this point, the upper locking area will engage 127b the connecting plate 127 with protruding element and the upper locking area 128b the connecting plate 128 with the receding element into each other, and at the same time engage the lower locking area 127c the connecting plate 127 with protruding element and the lower locking area 128c the connecting plate 128 with the receding element into each other. As in 15th shown is the connection between the connecting plate 127 with protruding element and the connecting plate 128 completed with a recessed element, and the outer shape consists of the two connecting plates connected to one another 127 and 128 corresponds to the outer shape of the side plate 122 .

It should be noted that the connection between the connecting plate 127 with a protruding element of a link unit 120 and the connecting plate 128 with a recessed element of a link-clamp adapter and the connection between the connecting plate 128 with a recessed element of a link unit 120 and the Connecting plate 127 with the protruding element of a link-clamp adapter can be carried out in the same way as when connecting two of the link units mentioned above 120 .

When such a rotary snap mechanism when connecting the link units 120 and the connection between a link unit 120 and a link-bracket adapter is used, since a connecting portion itself has a connecting force, the connection between the link units can 120 or the connection between the link unit and the link-clamp adapter can be made first and then the stopper links 130 to be built in. The stress caused by the assembly is significantly reduced and, at the same time, batch processing during assembly can be provided. Once assembled, the link unit and link-bracket adapter can be easily interchanged with other link units or link-bracket adapters of a different number of side plates. Therefore, the total length of the protection and guiding device 100 can easily be changed and adapted so that their functionality can be improved.

The connection between the link units and the connection between a link unit and a link-clamp adapter is preferably made by a direction of rotation that is not in direct relationship with a loading direction of the protective and guiding device. After connection, a force that is applied in a load direction during operation is absorbed by locking portions which are arranged in upper and lower regions around the protruding region and the recessed region, respectively, and form the rotary snap mechanism. All components are engaged with each other so that strength and durability are improved.

It should be noted that in the embodiment described above, one link unit consists of three side plates, but the number of side plates fixedly connected to one another can also be four, two or less. Furthermore, an embodiment without a side plate is even possible. With the number of side plates, the length of the total length of the protection and guiding device for cables can be adjusted exactly.

For attaching the device 100 between a stationary or a movable mounting end are thus at the ends of interconnected link units 120 Link-clamp adapter 161 , 162 , 163 and mounting brackets 150A , 150B provided, the connection between link unit 120 and link-bracket adapters 161 , 162 , 163 the connection of two link units 120 corresponds to, and the connection between the link-bracket adapter 161 , 162 , 163 and a mounting bracket 150A , 150B the connection between a link unit 120 and a stopper member 130 is equivalent to. The link-bracket adapter 161 , 162 , 163 can be done simply by cutting off a link unit 120 getting produced.

16 Fig. 3 is a perspective view of a link unit 220 from the outside, in which no side plate is provided. Both ends of the flexible link arms 226 extend from a connection area 224 off, being a connecting plate 227 with protruding element and a connecting plate 228 is provided with a receding element, which are each connected to corresponding adjacent link units. 17th Figure 10 shows the perspective view of the link unit 220 from 16 from the inside, ie from the cable receiving room side. It should be noted that the shapes of the connecting plates 227 and 228 , the connection area and its functions are those of the link unit described above 120 correspond.
