    SLIDING DOOR ARRANGEMENT Technical field The present disclosure relates to a sliding door arrangement comprising at leastone sliding door, at least one rail guiding the sliding motion of the door, a brakingdevice attached to one of the door and the rail, and a co|ector device, attached to theother of the door and the rail. The braking device interacts with the co|ector device tobrake the sliding motion of the door when the door approaches an end position.
    BackgroundSuch an arrangement is disc|osed for instance in EP-2050907-A2. One issue associated with sliding door arrangements in general is how to simplify installation,especially as this is often carried out by an end user.
    SummaryOne object of the present disclosure is therefore to simplify installation. This object is achieved by means of a sliding door arrangement as defined in claim 1.More specifically, a sliding door arrangement of the initially mentioned kind has aco|ector device, which has a base portion, attached to an attachment surface of thedoor or the rail, and an arm portion, which is pivotally connected to the base portionby means of a joint/hinge. Further, a biasing arrangement is connected to the baseand arm portions, and urges the arm portion to pivot at said joint towards the attach-ment surface, and an adjustment actuator, which is attached to the arm portion,projects towards the attachment surface and rests on the attachment surface or asurface connected to the attachment surface, such that adjusting the adjustmentactuator pivots the arm portion at the joint. This provides for easy and reliable adjust-ment of the co|ector device with sufficient accuracy.
    The co|ector device may be attached to the rail, and the braking device may beattached to the door or vice-versa.
    The biasing arrangement may include a spring, such as a torsion spring. Ahelical portion of the spring may be attached to the joint/hinge of the co|ector device.
    The rail may have a U-shaped cross section, in which the co|ector device maybe hidden.
    The base portion and the arm portion may be made by injection moulding aplastic material.
    The base portion may be attached to the rai| by means of a screw, the head ofwhich fits into a channel in the rai|. Further, protrusions on a surface of the baseportion may extend into this channel.
    Brief description of the drawinqs Fig 1 illustrates schematically a sliding door arrangement.
    Fig 2 shows an exploded view of a collector device.
    Fig 3 shows in partial cross section a collector attached to a rai| where thecollector interacts with a braking device, attached to a door.
    Fig 4 shows a cross-section through a rai| with an attached collector device.
    Detailed descriptionSliding doors are widely used, for instance to cover an opening to a closet or storage space, or to optionally divide a room into two parts. Fig 1 illustrates schema-tically a sliding door arrangement. Usually, two or more doors 1, 3 are used, whichtogether cover an opening 5 with some overlap when closed. A rai| arrangement 7, 9,usually employing a top rai| 7 and bottom rai| 9 may be used to guide the slidingmotion of a door between two end positions 11, 13. Alternatives exist where thebottom rai| 9 carries the weight of the door, and others where the door is suspendedfrom the top rai| 7. Combinations are also possible. ln order to avoid that a sliding door slams e.g. into the side of the opening, abraking device 15 is used that brakes the motion of the door when it is about to reachone of its end positions. Othervvise a door could be damaged, or could damage otherobjects. The braking device 15 can be combined with a retraction arrangement intoan attenuation- and retraction device that breaks the motion of the door and at thesame time pulls the door to the end position 11, as is well known per se.
    The braking device 15 interacts with a collector device 17 when reaching anend position. Typically, the braking device catches a protruding part of the collectordevice, or vice-versa. lf the braking device 15 is connected to the door 1, the col-lector device 17 may be connected to the rai| 7 as schematically illustrated in figure1, although the opposite arrangement, where the braking device is connected to therai| 7 and the collector device is connected to the door 1 is also possible. 2 The present disclosure is mainly concerned with how to accomplish the collect-or device 17. The collector device may be adjustable in order to deal with manu-facturing tolerances and tolerances that arise when the sliding door arrangement isassembled. The sliding door arrangement may often be assembled by an end user,and, if so, the end user should be capable of adjusting the collector device in areliable and easy way, typically such that it presents a protruding portion that reliablyinteracts with the braking device.
    Fig 2 shows an exploded view of a collector device 17. The collector devicecomprises a base portion 19 and an arm portion 21, which is connected to the baseportion 19 by means of a joint/hinge 23, which makes the arm portion 21 pivotablewith regard to the base portion 19. The base 19 and arm 21 portions may be madefrom injection-moulded plastic, for instance (30%) glass fibre reinforced polyamide(PA). The joint/hinge 23 may be made up from protruding pins 25 of the base portion19, which snap into holes 27 in the arm portion 21. Needless to say, the skilledperson is capable of providing a hinge orjoint in other ways.
    The base portion 19 may be attached to a surface of the rail 7, cf. fig 1, suchthat it is fixed with regard to the rail. This may be accomplished by means of a squarehead screw 29, which is inserted into a channel in the rail 7, matching the head of thescrew, wherein a threaded portion 31 of the screw extends through a hole 33 in thecollector base portion 19. A nut 35 may be firmly attached to this threaded screwportion 31 on the other side of the base portion 19 in order to attach the base portion19 to the rail 7. However, it should be noted that other ways of attaching the baseportion 19 to the rail 7 are possible, such as e.g. fastening the base portion by meansof a screw from below, which is fastened to e.g. the ceiling above the rail.
    A biasing or pre-tensioning arrangement in the form of a spring, in the illustratedcase a helical torsion spring 37 is used to bias or pre-tension the collector device armportion 21 _ A helical part of the spring may for instance be attached to inward extend-ing pins 39 of the base portion 19, and the ends 20, 22 of the spring act on the bot-tom surfaces, as seen in fig 2, of the base 19 and arm 21 portions, respectively. Thismeans that any pivoting movement of the arm portion 21 relative to the base portion19 clockwise as seen in fig 2, away from the rail, will tension the spring 37 to counter-act this movement. The joint may be provided with a limiter which gives a maximumflexing of for instance 30° which protects the spring from being permanently deform-ed.
    An adjustment actuator in the form of an adjustment screw 41 is attached to thearm portion 21 by being inserted in a threaded hole. The top end of this screw maywhen inserted rest on the rai|. Thereby, adjusting the screw pivots the arm portion atsaid hinge. Thanks to this arrangement, turning the adjustment screw 41 moves thefree end 43 of the arm portion 21 towards or away from the rai| 7, the spring 37making sure that the end of the adjustment screw remains in contact with the rai| 7.
    The user may thus very accurately adjust how much the free end 43 protrudesfrom the rai|, and it is the free end 43 that interacts with a braking device, or an at-tenuation- and retraction device.
    This is i|ustrated in fig 3, which shows a co|ector 19, 21, 23 attached to a rai| 7that interacts with a braking device, a protruding portion 45 of which is visible in fig 3.The co|ector device and the rai| are shown in cross section. ln the i|ustrated case,the door rests on wheels running on a bottom rai| (not shown). The top rai| 7 has anupside-down U-shaped cross section across its |ongitudina| direction. Wheelsattached to the top part of the door may run on the inside of the legs of the U-shapein order to stabilise the top of the door laterally with regard to the travelling directionof the door 1. The co|ector device can be hidden inside the U-shaped cross sectionof the rai| 7.
    Fig 3 shows how the free end surface 43 of the co|ector arm portion 21 caninteract very accurately with a protruding portion 45 of the braking device, thanks tothe adjusting arrangement. The adjustment screw 41 rests on the rai| 7, and thespring 37 urges the arm portion 21 upwards in order to obtain this. The user canadjust the screw e.g. by means of an Allen key. As i|ustrated, the arm portion 21 mayalso provide a surface 47 facing towards the adjacent end of the rai|, this surfacebeing adapted to interact with a retraction device that may pull the door 7 to the endposition.
    Fig 4 shows a cross-section through a rai| 7 with an attached co|ector device,as seen from the adjacent end of the rai|. The rai| 7 is a double rai| with U-shapedopenings for two sliding doors. As i|ustrated, each opening has a channel 49, wherethe head of a screw 29 fits in the channel, as previously mentioned. The channel 49has an opening with a narrower width as compared to the channel as a whole, suchthat the screw head can rest on the opening. The rai| 7 may be made of extrudedaluminium and may thus substantially have the same cross section along its length.Therefore, the position of the co|ector 17 along the length of the rai| may be easily 4 adjusted by slightly Ioosening the nut 35 and sliding the base portion 19 to a desiredposition on the rai| 7. The collector device may also be easily replaced, even withoutremoving the screw 29.
    As shown in fig 2, the upper side of the base portion 19 may be provided withprojections 34 that enter the channel 49 to provide a steering function that aligns thelongitudinal direction of the collector device 17 with the one of the rai| 7.
    The present disclosure is not restricted to the examples given above, and maybe varied and altered in different ways within the scope of the appended claims.
