    THREADING DEVICETECHNICAL FIELD The present invention relates to a threading device for threading a line orcable repeatedly past cross members of a cable ladder. The threadingdevice can also be used when threading a mooring line of a boat througha mooring ring. By the use of the threading device, a cable can be pulledpassed the cross beams of the cable ladder in an easy way with the userstanding on the floor beneath the cable ladder. ln this way, a cable can beinstalled on the cable ladder without having to thread the cable to passeach cross beam. One advantage of the threading device is that theinstallation operation can be performed from underneath the cable ladder, without having to reach the upper side of the cable ladder.BACKGROUND ART When installing a cable in a larger building or in a factory, several cablesare normally routed in specific cable ducts in order to provide a well-arranged cable installation that is easy to maintain. Separate cables areoften installed side by side on cable ladders or cable trays. Some cabletrays are closed and some cable ladders or cable trays are open. Differentcables conducting different signals and different voltages are oftenseparated some or are installed on separate cable ladders. A cable laddercomprises two longitudinal bars or beams interconnected by crossmembers or rungs arranged at a specific distance, which may be e.g.between 20 - 50 cm depending on the size of the cable ladder.
    One problem when installing a cable on a cable ladder is that the cableladder is often positioned high, close to the ceiling or at least above headheight of humans. When installing a cable, the electrician must stand on aladder or a platform in order to be able to reach the upper side of the cableladder, where the cable is installed. Cables may be installed one by onebut normally, a cable bundle comprising several cables is pulled over the cable ladder by the use of a pulling line. However, the pulling line mustfirst be positioned on the cable ladder, which is time consuming anddifficult due to the high position of the cable ladder. ln order to reach theupper side of the cable ladder, a platform or a ladder must be used. Theplatform or ladder may be unstable and must be moved constantly in orderto reach into the complete cable ladder. The installation of several cables at the same time is normally performed in new installations.
    When a single cable is to be installed at a later stage, e.g. in a buildingthat is being used, it is often unpractical to use a platform. ln such a case,a ladder can be used. A ladder may however be unstable and it has to bemoved constantly in order to reach the complete cable ladder. Often thecable ladder is concealed by a dropped ceiling which consists of agridwork of metal channels holding ceiling tiles or panels. The panels areremoved in order to reach the cable ladder. However, the installation of acable is difficult since the cable must be threaded past both the crossmembers of the cable ladder and the grid work of the ceiling. This is oftenthe case when a new communication line or a fibre is to be installed e.g. inan office building. Different threading devices have been proposed,adapted to thread a wire or line through a single ring shaped member.These threading devices are mainly adapted to simplify the mooring of aboat to a buoy or the like, where a single threading action is enough.
    US 4,560,098 relates to a device suitable for threading a line through aring member or the like. This solution is adapted for a single threadingaction in a predetermined direction. DE 10 2006 029 810 A1 discloses adevice for threading a line through a ring member or the like. This deviceis adapted to a single threading action and the device must be moved intwo different directions in order to thread a line through a ring member. GB287,40 and GB 442,85 show further examples of threading devices.
    Both are rather complicated and require a specific looped line end to function. WO 2009124934 A1 shows a threading device adapted for asingle threading action of a line through a mooring ring.
    There is thus a need for an improved threading device adapted to simplify the installation of a cable on a cable ladder.DISCLOSURE OF INVENTION An object of the invention is therefore to provide a threading device forrepeatedly threading a cable past cross members of a cable ladder.
    With a threading device for threading a line or cable past a cross memberof a cable ladder, comprising a housing, a rotatable arc-shaped elementsuspended in the body and having an opening, and a line or cable holdingmeans arranged to slide on the arc-shaped element, where the arc-shaped element is adapted to assume a first position with the opening in afirst direction and a second position with the opening in a second direction,and further comprising transfer means adapted to transfer a movement ofa handle to an outer surface of the arc-shaped element in order to rotatethe arc-shaped element between the first position and the second position,the object of the invention is achieved in that the threading device furthercomprises a resilient means adapted to return the arc-shaped element toits starting position, and that the resilient means can be set in a first stateadapted to return the arc-shaped element to the first position and in asecond state adapted to return the arc-shaped element to the secondposition.
    By this first embodiment of the threading device according to the invention,a threading device is obtained which is adapted for a repeated threadingof a cable over a plurality of cross members of a cable ladder. The arc-shaped element is returned to its starting position by a resilient means,which allows a user to repeatedly perform a plurality of threading actions,e.g. when threading a line or cable past a plurality of cross members of acable ladder. This allows for a time efficient threading of a line or cable, without the need to use a ladder or platform in order to reach above thecable ladder. The resilient means can be set in a first state or in a second state, allowing for a pulling threading action or a pushing threading action. ln an advantageous further development of the threading device accordingto the invention, the resilient means can be set in a third state, in which thearc-shaped element is not returned to its starting position. ln this way, thethreading device can be used for a single threading action, e.g. for themooring of a boat at a mooring ring. lt is also possible to use a lockingmeans to lock the arc-shaped element in a fixed position, preferably in thefirst position. ln this way, the threading device can be used e.g. as aconventional boat hook. ln an advantageous further development of the threading device accordingto the invention, the outer surface of the arc-shaped element is providedwith a plurality of teeth. The teeth are adapted to interact withcorresponding teeth of a transfer means, which is used to rotate the arc-shaped element from the first position to the second position or from thesecond position to the first position. ln an advantageous further development of the threading device accordingto the invention, the transfer means comprises several balls and a pusherarranged in an endless ball channel. This gives the threading device asmooth operation and provides low friction for the movement of the arc-shaped element. The use of a pusher to move the balls in the ball channelallows for an operation in both directions. The cable is attached to thecable holding means and the cable is then forvvarded past the crossmembers of the cable ladder from below. When several cables are to beinstalled at the same time, it is possible to first thread a pilot pulling lineover the cable ladder which is attached to the cables. The cables are thenpulled in position by the pulling line. The transfer means may also be achain, a toothed drive belt or a roller chain. ln an advantageous further development of the threading device accordingto the invention, the pusher is attached to a handle, such that the arc-shaped element is moved between the first position and the secondposition by pulling or pushing the handle. By mounting the pusher to ahandle, the length of the threading device can be adapted to the height ofthe cable ladder. The handle is preferably telescopic and extendable. ln an advantageous further development of the threading device accordingto the invention, the resilient means is an elastic band attached to thehandle and to at least one slider, where the elastic band runs over at leastone pulley. By using an elastic band and at least one pulley changing thedirection of the elastic band, a relatively uniform force can be obtainedfrom the elastic band over the complete rotational movement of the arc-shaped element. ln another embodiment of the threading device according to the invention,the pusher of the threading device is a toothed wheel driven by a motor.The motor may be controlled by switches operated by the user. The motorcan drive the arc-shaped element from one position to the other positionand a resilient means can return the arc-shaped element to its startingposition. lt is also possible that the motor preloads the resilient means andthat the arc-shaped element is returned to the starting position byreleasing the resilient means by a switch. lt is also possible that the motordrives the arc-shaped element from one position to the other position andthat the motor also returns the arc-shaped element to its starting position.

    Figs. 1 to 3 show a first embodiment of the inventive threading device. Thethreading device 1 comprises a housing 2 having outer side walls. Theside walls are parallel and are positioned apart with a predefined distance.The housing 2 comprises a head 16 and an elongated body 17. ln thehead, a circular arc-shaped element 3 is arranged. The arc-shapedelement 3 is provided with teeth 6 on the outer surface 14. The toothedarc-shaped element extends out of the body and is part-circular with anopening 4 having an opening angle preferably extending over a rangebetween 60 and 120 degrees. The diameter of the opening in the arc-shaped element is determined on the size of the cross beams of the cableladder, and is preferably larger than 6 cm.
    The arc-shaped element is in the shown example provided with a groove22 which will slide in correspondingly shaped protrusions in the head. lnthis way, the arc-shaped element can be held in position in the head andwill be able to rotate in the head. The arc-shaped element will rotate withthe opening facing inwards towards the head, and the rotation of the arc-shaped element is approximately 270 degrees. The arc-shaped element isfurther provided with a slit 23. A cable holding means 5 extends throughthe slit 23 and will slide in the slit when the arc-shaped element rotates.The length of the slit preferably corresponds to the amount of rotation ofthe arc-shaped element, such that the cable holding means can act as endstops of the rotation. The arc-shaped element 3 is adapted to assume afirst position 25 with the opening in a first direction and a second position26 with the opening in a second direction.
    The outer surface of the arc-shaped element is in the shown exampleprovided with teeth 6 adapted to interact with a transfer means adapted torotate the arc-shaped element from the first position to the second positionor from the second position to the first position. The transfer means maye.g. consist of balls, a chain, a toothed drive belt or a roller chain. lt ishowever important that the transfer means has a relatively long extensionsuch that it can interact with the arc-shaped element through the completerotation of the arc-shaped element. ln the shown example, the angularopening of the arc-shaped element is approximately 90 degrees and thetransfer means extend over approximately 120 degrees. ln this way, thetransfer means will always be in contact with part of the arc-shapedelement during a rotation of the arc-shaped element from one position tothe other position. ln the shown example, balls are used as the transfer means. lnside thehousing 2, an endless ball channel 9 is arranged. ln the endless ballchannel, a plurality of balls 7 and a pusher 8 are arranged. The pusher isadapted to push the balls in a forward or backward direction in the ball channel, depending on the desired rotational direction of the arc-shapedelement. The end surfaces of the pusher may be provided with sphericalsurfaces adjacent the balls such that an end surface resembles part of aball. This allows the pusher to push the balls in a smooth and reliable way.The pusher 8 extends out of the ball channel with an attachment section18 adapted to be attached to a handle 10 with e.g. screws. Theattachment section runs in a groove in the ball channel and can move in alongitudinal direction along the elongated body 17. The pusher can movebetween a fon/vard end position 20 and a rearvvard end position 21. Thedistance between the forward end position 20 and the rearvvard endposition 21 preferably corresponds to the amount of rotation of the arc-shaped element, such that the pusher can act as an end stop for therotation of the arc-shaped element. The length of the body is preferablymatched to the distance between the forward end position 20 and therearvvard end position 21.
    The ball channel is filled with balls apart from the pusher. The toothedouter surface of the arc-shaped element 3 extends into part of the ballchannel in the head of the threading device. When the pusher is moved inone direction, the pusher will push the balls in the same direction. Theballs will glide or rotate and push each other in the same direction, and thetoothed outer surface of the arc-shaped element will rotate in the desireddirection, moving the arc-shaped element from one position to the otherposition.
    The attachment section 24 of the pusher 8 is fixedly attached to a handle10, e.g. by screws or rivets. ln this way, the pusher can be moved bypulling or pushing the handle. ln the example shown in Fig. 1, the pusheris in the forward end position 20, i.e. in the inner position, and the arc-shaped element 3 is in the first position 25. ln this position, the inner endof the handle 10 is also at the end position 20. By pulling the handle, thepusher and the handle will move away from the head of the threading device, towards the rearvvard end position 21. At the same time, the ballswill rotate the arc-shaped element counter-clockwise from the first position25 to the second position 26, as shown in Fig. 2.
    By pushing the handle from this extended position, the pusher and thehandle will return to the forward end position 20 and the arc-shapedelement will return to the first position 25, i.e. the starting position, with a clockwise rotation.
    The shown threading device is provided with a resilient means 11 which isadapted to return the arc-shaped element to the starting position. ln theshown example, the resilient means is an elastic band which runs over afront pulley 12 and a rear pulley 13. One end of the elastic band isattached to a first slider 18 and the other end of the elastic band isattached to a second slider 19. ln the shown example, the first slider 18 ispositioned in the forward end position 20 and is attached to the handle 10,close to the position of the attachment section 24. The second slider 19 ispositioned at the rearward end position 21 and bears at the body. ln thisexample, the elastic band will run from the second slider 19, over the rearpulley 13, over the front pulley 12 to the first slider 18 which is attached tothe handle.
    By pulling the handle, the elastic band is extended at the same time as thearc-shaped element is moved from the first position to the second position.When the handle is fully extended, such that the inner end of the handle,the pusher and the first slider is in the rearward end position, the elasticband has been extended by approximately twice its length. This position isshown with dashed lines in Fig. 3b.
    When a cable is threaded over a cross member of a cable ladder, theinner surface of the arc-shaped element will bear on a cross beam of acable ladder. ln this way, the inner surface will slide and rotate on thecross beam, which at the same time will provide the reaction force to the pulling force of the handle when the handle is pulled. ln this way, thethreading device can be operated with one hand. When the arc-shapedelement is in the second position and the arc-shaped element is releasedfrom the cross beam, the elastic band will pull the handle back to thestarting position, i.e. to the inner position, and the arc-shaped element willat the same time return to the first position, i.e. to the starting position. Thecable has now passed the cross member and the threading device is ready to thread the cable passed another cross member.
    The second slider 19 is in the shown example positioned at the rearwardend position 21. ln this way, the pusher can be pulled from the forwardend position 20 to the reanNard end position 21 and is returned by theelastic band to the forward end position 20. The second slider 19 may alsobe attached to the inner end of the handle when the inner end of thehandle and the pusher are positioned at the rearward end position, withthe arc-shaped element in the second position 26. ln this case, the firstslider will be positioned at the forward end position 20. The elastic bandwill in this case run from the second slider 19, over the rear pulley 13, overthe front pulley 12 to the first slider 18. ln this way, the starting position ofthe pusher will be the rearward end position 21. By pushing the handleinwards, the pusher will move from the rearvvard end position to theforward end position and the arc-shaped element will move from thesecond position to the first position.
    When threading a cable over a cross member of a cable ladder, the innersurface of the arc-shaped element will bear against the cross member ofthe cable ladder, such that the handle can be operated by one hand.When the arc-shaped element is released from the cross member, thepusher and the handle will be pulled back to the starting position by theelastic band and the arc-shaped element will be returned to the starting position, which in this case is the second position. 11 The threading device is preferably provided with a pin or the like that willallow a user to select which slider that is to be attached to the handle. lnthis way, the user can decide which type of action that the threadingdevice should be operated with. By attaching the first slider 18 to thehandle, a pulling action is obtained, by attaching the second slider 19 tothe handle, a pushing action is obtained. Some users may prefer a pullingaction and some users may prefer a pushing action.
    The resilient means can also be set in a third state in which the arc-shaped element is not returned to its starting position. This may be doneby releasing the resilient means from the handle, e.g. by leaving both thefirst slider and the second slider unattached to the handle. ln this way, thethreading device can be used for a single threading action, e.g. for themooring of a boat at a mooring ring. lt is also possible to use a lockingmeans, e.g. a releasable button, a pin or the like, to lock the arc-shapedelement in a fixed position, preferably in the first position. The lockingmeans may act directly on the arc-shaped element, directly on the handleor may block the transfer means. ln this way, the threading device can beused e.g. as a conventional boat hook. lt is also possible to use a coil spring as the resilient means. A coil springmay be arranged inside the handle, e.g. between the rear part of the bodyand a position at the rear end of an elongated handle. Depending onwhere in the handle the rear end of the coil spring is attached, a pullingforce or a pushing force can be provided by the coil spring. When a coilspring is used, it may be preferred to elongate the body somewhat in orderto provide a relatively uniform spring force from the coil spring.
    The housing is preferably made from a reinforced plastic, such as a fibrereinforced polyamide. The arc-shaped element is preferably manufacturedfrom a strong and rigid material. lt can be cast or machined from a metalor may also be made from a reinforced plastic, such as a fibre reinforced polyamide. 12 ln a second embodiment of the threading device according to theinvention, shown in Fig. 4, the pusher of the threading device is a toothedwheel 31 driven by a motor 30. The toothed wheel is positioned in theend|ess ball channel, which in this example is much shorter than in theembodiment described above. The toothed wheel 31 will be rotated by themotor such that the balls are moved in a forward or rearvvard direction.The balls will rotate the arc-shaped element from one position to anotherposition. The motor is preferably positioned perpendicular to the toothedwheel in order to fit in a handle, which means that the toothed wheelpreferably is driven through a worm drive comprising a worm and a wormgear. ln this way, the rotational speed of the motor will also be reduced and the torque of the motor will be increased.
    The motor may be controlled by switches 33 operated by the user. Themotor can drive the arc-shaped element from the first position to thesecond position by e.g. activating a forward switch, and drive the arc-shaped element from the second position to the first position by activatinga backward switch. lt is also possible that the motor drives the arc- shapedelement from the first position to the second position and that a resilientmeans returns the arc-shaped element to its starting position. The resilientmeans may in this case be a clock spring arranged at the toothed wheel.The motor may also preload the resilient means such that the resilientmeans will drive the arc-shaped element from the first position to thesecond position by releasing a catch, and the motor will then return thearc-shaped element to its starting position. The motor is preferablypowered by rechargeable batteries 32, which may be built in or may be exchangeable.
    Fig. 5 and 6a - 6f demonstrates the installation of a cable on a cableladder by using the inventive threading device. The cable ladder 40comprises a plurality of cross members or rungs 41. Since the cableshould be installed on top of the cable ladder, the cable must be threaded 13 over each cross member. The end of the cable is attached to the cableholding means in a secure way. The threading device is then placed at thefirst cross member with the inner surface of the arc-shaped elementresting on the cross member, with the arc-shaped element in the firstposition, as shown in Fig. 6a and 6f. The threading device is pulled by thehandle which causes the arc-shaped element to rotate from the firstposition to the second position, see Figs 6b - 6d. By pulling the handle,the handle extends outwards and extends the resilient member. The endof the cable will now be on the other side of the cross member and thethreading device can be released from the cross member and can bemoved to the next cross member. At the same time, the arc-shapedelement is returned to the first position by the resilient means, and thehandle is returned to its inner position, as seen in Fig. 6e. The threadingdevice is now ready to thread the cable over the next cross member. Atthe next cross member, the inner surface of the arc-shaped element isagain placed bearing on the cross member and the handle is pulled. Theend of the cable will now pass the cross member and the process can be repeated until the cable end has passed all cross members.
    The invention is not to be regarded as being limited to the embodimentsdescribed above, a number of additional variants and modifications beingpossible within the scope of the subsequent patent claims. lt is e.g.possible to integrate the threading device in different types of handles, andthe rotatable, arc-shaped element can be suspended in the body of the threading device in a number of ways encompassed by the claims. 14 REFERENCE SIGNS ¿9 ¿¿¿ ¿:P ¿.UF ¿9 ¿h' ¿9 ¿9 m9 mmmm:FFPNf m.UF m9 co9 OO¿ 4>4>coco#999 Threading deviceHousingArc-shaped elementOpening Cable holding meansTooth Ball Pusher Ball channel Handle Resilient meansFront pulley Rear pulley Outer surface Inner surface Head Body First slider Second sliderForward end positionRean/vard end positionGroove Slit Attachment sectionFirst positionSecond positionMotor Toothed wheelBattery Switch Cable ladder Cross member
