    ABSTRACT A cable tie(l) with means (8,9,lO,ll,l2) to form aloop(5) in order to mount cables(l9) against apanel(l3,l5) or a marking badge(20). The cable tie has anintegrated panel anchor(2) having a wider flattened bodythat have one or more weaker segments that areperpendicular to the longitudinal axis if the cable tie.The cable tie is intended to be folded in said weakersegments and then mounted into a long and narrowopening(l4) in a panel(l3). The weaker segments are made of grooves(3), cut throughslots(4), elastomeric bridge(6) or a combination thereof.The mounting starts with a bending around the panelanchor, then the panel anchor gets folded in the weakersegments. After that the panel anchor is mounted into theelongated opening(l4) and then rotated 90°, turning thefolded panel anchor(7) perpendicular to the elongatedopening(7). When releasing the bending, the band on eachside of the panel anchor is fixed in the long and narrowopening(l4) and the edges(l8) of the panel anchor isfixed towards the back-side of the panel. 12

    A CABLE TIE FOR MOUNTING OF CABLES DESCRIPTION OF THE INVENTION This invention relates to a cable tie(l) designed tocollect and hold one or more cables(l9), tubes, hoses orsimilar details against a panel. The cable tie is made ofplastic, normally PA(Nylon). It consists of a band withmeans to form a loop(5). This description will focusmainly on a cable tie consisting of one end with aribbed(8) side and the other with a locking device(9)formed as a hole(lO) that can receive the ribbed part anda locking mechanism(ll) inside locking the loop in atightened position. The function of forming a loop couldhave any kind of mechanism since the claims of theinvention is focused around mounting the cables(l9)towards a panel(l3,l5). The ends could actually justconsist of holes designed for mounting of Velcro band,but the benefit of the design with locking devicedescribed above is that it is extremely robust and whentightened to engage the locking mechanism it will be evenmore robustly mounted to the panel.
    There are types with a release function(l2) integrated inthe locking mechanism that can open up the loop andeasily dismount the cable tie. This release function issuitable for this invention since one of its advantagesis the easy way of mounting and dismounting it from thepanel. The cable tie is therefore a band of plastic withmeans to form a loop(5).
    The cable tie has, on a specific place along its length,a panel anchor(2) for panel mounting that can be mountedinto an opening(l4) in a panel(l3). The panel anchor(2)is a flat and wide part integrated with the cable tie.This panel anchor have segments that are weaker andtherefore can bend, turning the flat panel anchor(2) intoa folded panel anchor(7). The weaker segments areelongated sections that are perpendicular to thedirection of the cable ties elongated axis. The weakeningof these segments are made either by grooves(3), cut-through slots(4) or by a double molded elastomericbridge(6), a part that are integrated with the cable tieon both sides. The weakening can also be made of acombination of these three. The weakening can be only onesegment or a number of parallel segments acting likehinges. After folding, the folded panel anchor(7) gets anelongated shape with a V- or U- shaped cross section(seedetail C of figure l2) depending of the number ofgrooves. The grooves(3) can be made from one or bothsides of the flat part. Parts of the grooves can havecut-through slots(4) in order to make the bending easier.
    The opening in the panel(l4), aimed to receive the foldedpanel anchor(7), has a long and narrow shape of arectangle, oval or ellipse, alternatively it can have ashape that is the sum of a circle(l6) and a long andnarrow shape that are overlapping, this is morebeneficial for thick panels(l5). The width of the longand narrow opening is slightly bigger than the width(W)of the band and the length of the long and narrow openingis slightly longer than the width(L) of the panelanchor(2). It is an advantage, as will be shown later,that the band on each side of the anchor has an outwardtension after being mounted into the panel. The benefitof folding the panel anchor into an elongated shapeinstead of molding an integrated elongated body (seeBerglund GB2509002) is that it is molded as a flat cabletie. There is no need for curves in order to get theright positioning between the folded panel anchor and theband. A flat cable tie is an advantage in production,since the molding tool is simpler and cheaper. Most ofall, it is easier to handle ,pack and store these cableties since they take up less space and they don't havethe same tendency to hook into each other as with themolded panel anchor(Berglund GB2509002) that arepositioned offset from the band.
    PA, polyamide often used in cable ties have a tendencyto break if the bending stress is high combined with alow humidity in the air. PA absorbs and releases water asthe surrounding air humidity changes, so in the middle ofthe winter in the northern parts of Europe it might breakwhen the bending forces are too tough. Therefore it mightbe an advantage to use a type of plastic that can takethe tensions in the thin areas under the grooves. Thelong term effects is not important because if it wouldbreak in these areas after mounting it will just be splitup in two panel anchors, if it is correctly mounted thetension of the band will still be there, although itmight lose some rigidity against rotation. Plastic hingescan break if they are bent back and forth many times butthis is not the case here. The critical phase here is theinitial bending prior to mounting and normally it willonly be mounted once. If PA is used it is important tochoose a type that is modified to endure stress, at leastonce. But if the double molding is used with anelastomeric bridge(6) there is now risk that the cabletie will be split up in two pieces. Elastomer is likerubber but it can be molded in the same machines thatmold plastic, and the bonds between them are very strong.The molding is done in a so called 2K-molding where bothplastic and elastomer is molded in different tools but inthe same machine. These tools are more complicated and expensive but the product will be extremely robust withno risk for cracks and breakage when mounted.
    The direction of the long and narrow opening should beperpendicular to the directions of the cables, tubes orhoses to be mounted to the panel.
    The mounting starts with a bending(Fig. l2) of the twosides of the panel anchor, this makes the flattened panelanchor bend, in the weaker segments. Then the foldedpanel anchor can be mounted into the panel opening(Fig.l3). First the folded anchor is mounted through theopening until it is completely on the backside of panel,after that the cable tie is rotated 90°(Fig l4). Therotation can be done in any direction even though thepicture is showing only one. After that the bending isreleased(Fig. l5). The tension from the initial bendingis now trying to restore the band into its original flatshape and by doing that the band will be fixed into thetwo ends of the long and narrow opening and the edges(l8)of the folded panel anchor(7) will be pushed towards thebackside of the panel. In this situation the cable tie ismounted quite loosely but still locked in all directionsplus rotation. Then when it is tightened aroundcables(l9) the whole area around the anchor is tightened,pushing the edges(l8) of the panel anchor that areparallel to the weakened segments against the backside ofthe panel, it is fixed.
    Since the 90° rotation can be chosen in any direction,the choice is made so that the making of the loop iseasy, the side where the space is sufficient at thatspecific spot.
    The distance between the locking mechanism and the anchoron the cable tie should not exceed the diameter of thesmallest cable to be mounted.
    One advantage with this specific type of cable tie isthat it fits in panels with different thicknesses. As anexample, the panel thickness that one cable tie type canfit might be in the range of l-4mm. And that covers mostof the plates used when building cars, airplanes andmachines that needs a lot of mounted electrical cables.When the panel is thick it is an advantage with achamfer(l7) on the openings front side edges, at least onthe circular part(l6) of the opening. With a thinpanel(l3), the simple long and narrow opening withoutchampers or circular parts are sufficient. It might alsobe an advantage to make the opening slightly bigger whenplaced on a thicker panel. In that way the range ofdifferent thickness that one single cable tie can fitwill be increased. Another advantage with the panelanchor of this type is that it can also fit in openingson panels that are not flat. Vaulted or curved plates,that are common in cars, airplanes and machines is not a problem, and it works for the same reasons describedabove for handling different panel thickness.
    This cable tie can also be used for marking cables, partsand details with article numbers, text or symbols. Thenall you need is a small plate with text or otherinformation, this marking plate shall also contain thelong and narrow opening(l3). Then the anchor is mountedto the marking plate opening before the cable tie ismounted and tightened around the detail to be marked.
    The cable ties are easy to manufacture as molded parts, asimple molding tool with only two halves, and no need forany moving inserts in the tool. There might be achallenge to fill the mold since the thinner areas underthe grooves might obstruct the flow of melted plastic,but with the thinner area longer than the width of theband the cross section area should be about the same.Normally these issues are solved by carefully placing theinlet of melted plastic and outlet of air in the moldingtool design.
    Even though one type can fit into different panelthicknesses, there will probably be a need for a numberof variations, such as sizes, colors, an extra big loopor a version with double anchors, used for both mountingand marking. Despite the above mentioned differences,there is a big probability that one type is sufficient todo all cable attaching job in one machine.
    STATE OF THE ART AND DESCRIPTION OF PROBLEMS TO BE SOLVED Cable ties made of plastic, normally Nylon (PA), is acommonly used technique to mount things to each other.The big advantage is that they are very robust and theloop they create is very flexible in size in the way thatone single cable tie can be used to fasten things ofdifferent sizes, but when fastening a bunch of cablesagainst something, you normally need to let the cable tiewrap around that something. When it is to be fastenedagainst a panel or a plate, two holes can make it, if youenter in one and go back out through the other and thenform the loop around the cables. One problem is that onedoes not always have access to the backside of the plate.In different kinds of machines it is normal that thecables are fastened against the chassis or similar wherethere is no access to the backside to enable you to enterone hole and go back in another. With the presentinvention and the specially shaped hole in the samechassis we can just enter the anchor part through thehole and rotate 90°, and then form the loop around thecable bunch.
    One type of existing cable tie has a snap function inorder to snap into a round or square hole, see forexample Franks Patent WOZOO5/099402. These are mostlyadapted for one particular panel thickness, but there aretypes that are designed to fit two different thicknessesby having two snap functions at different depths. Thetype that snaps into a round hole does not have a lockingfunction against rotation. Normally these are alsodifficult to dismount without having access to thebackside of the panel since under normal circumstancesone would have to squeeze the snap function together fromthe back in order to dismount it. There are cable tiesthat are dismountable from the front but then the snapfunction tends to grow so that the cable(s) no longer isclose to the panel. When the cable is mounted offset fromthe panel the robustness against mechanical vibrationdeclines significantly. Also, for reason ofelectromagnetic disturbances (EMC-problems) it is betterto have the electrical cables clamped close to a metallicplate, it prevents the cable from becoming an antennadipole that can send or receive electromagnetic noise.
    Yet another type of panel mounting for cable ties is aso called tree-mounting type, it has a protrudingmechanism that looks like a Christmas-tree with branchesof decreasing length closer to the top. The mechanism ismounted into a round or square hole with the top firstand its branches are deformed and the mechanism getsstuck. This type is independent of the panel thickness and it can even fit into different sizes of holes but isnot very robust and can easily get loose if exposed toforces or vibrations. A somewhat similar type has a partof a plastic rivet integrated with the cable tie, it's atube like protrusion that is split in two halves from thetip. The protrusion is mounted into the hole and then aplastic sprint is pushed into the tube protrusion forcingthe two halves aside and making it expand on the backsideof the panel. They are robust but consist of two partsand are therefore more expensive. When mounted, the bendis quite tough and puts a lot of stress to the split tubepart and can cause it to break, especially in the winterwhen the humidity in the air is low. It works on onethickness only and also lacks protection againstrotation.
    There are also cable ties with one surface covered withadhesive to be attached to the plate or a hole for screwmounting it towards the panel. They can either beintegrated with the cable tie or a separate part with asmall loop that the cable tie can be mounted through. Theadvantage with the adhesive type is that you do not haveto make a hole in the panel but it is hard to find thebalance between sticking to the plate and a possibilityto remove it later on. With time adhesives also have atendency to dry out and loose the adhesiveness,especially in a warm environment, as in many machines.The type with a screw is very robust but a threaded holehas to be made either directly in the panel if it isthick enough or by mounting a thread insert. The problemis that it takes time to both make the thread and thenscrewing it in place. To simply punch a hole, even if itis a little bit complex is very cheap and is madeautomatically.
    As mentioned earlier Berglunds patent GB2509002 issimilar to the present invention but the curves makes itmore difficult to handle in production, packaging andwhen being used in the field. The curves close to thepanel anchor gives the unmounted cable ties a tendency tohook into each other and therefore makes them lessefficient for the manufacturer and user.
    To summarize, the existing cable ties often have one or more of the following drawbacks: l.
