    The present invention relates to a roof rack (10) adapted to be arranged on a flange (11) directed towards the roof with a first and a second side (13, 14). The roof rack (10) comprises a roof part (20) adjustably arranged to a working part (50), and adapted so that post-assembly abuts against a roof surface (12). The roof part (20) comprises a coupling device (30) for releasably attaching the roof rack (10) to the flange (11). The coupling device (30) comprises at least a first and a second coupling part (31, 32) arranged to cooperate with each other and in the direction of each other on each side of the flange (11) with a force (P1, P2) so that said coupling device (30) is kept connected to the flange (11). The force (P1, P2) arises as a function of gravity. The working part (50) has a working surface (51) for relief or work. The force (P1, P2) is transmitted via the roof part to said first and second coupling part in a direction parallel to the roof surface (12). The present invention has a simple construction which provides a strong coupling to a flange on a roof. (Figure 1 for publication)

    15 20 30 PG182xxSEOO 2 provides a good power transmission to the flange. A large contact surface with the flange can be used.
    The above-mentioned force can be said to be a first and a second force in opposite directions to each other.
    According to an aspect of the present invention, the roof part has a first and a second longitudinal bar, the first coupling part being arranged to the first longitudinal bar and the second coupling part being arranged to the second longitudinal bar. This provides a good power transmission between the roof part and the coupling parts on the coupling device.
    Preferably, the first and second coupling parts each have a substantially elongate shape. With a substantially elongated shape, a large contact surface can be obtained, which gives a high friction between the contact surface and the flange. The elongate coupling parts have a first and a second short side, wherein in connection with the first and the second short side a coupling rod (Išßa, 33lo, Söa, 35b) is loosely arranged to the first and second longitudinal rod (23, 24). This provides a robust coupling device which can withstand high pressures and gives a high friction between the involved surfaces. According to one aspect of the present invention, the sum of the lengths of the first coupling rods is longer than the length of said first transverse rod on the roof part.
    This means that the roof rack cannot, without significant deformation or breakage, accidentally come loose from the flange. In the same way, the sum of the lengths of the second connecting rods can be longer than the length of the first transverse rod on the roof part. This further improves the property that the roof rack cannot, without significant deformation or breakage, accidentally come loose from the flange.
    According to one aspect of the present invention, the first and second coupling members each comprise a substantially rectangular contact surface adapted to abut the flange after mounting. This means that a relatively large contact area can be obtained. For example, the area of the contact surface can be 5 ~ 40 cm 2, preferably 5430 cm 2, preferably 8- »25 cm In one embodiment, the area of the contact surface is 5-40 cm 2, preferably 5-30 cm 2, preferably 8 ~ 25 cm 2, regardless of the shape of the contact surface. In one embodiment, the first and the second exhibit PG182xxSEO0 cm 2, more preferably 8-25 cm 2.
    The roof part can have a first and a second transverse side, a first and a second longitudinal side, the working part being rotatably arranged to the roof part in connection with the first transverse side of the roof part, for example by hinges or by a flexible but durable material, such as leather or a nonwoven fabric .
    Between the roof part and the working part extends at least one adjusting rod, preferably two, pre-adjusting the angle between the roof part and the working part.
    The first and the second longitudinal side of the roof part constitute in one embodiment a first and a second longitudinal bar, and that said first and second transverse side of the roof part consist of a first and a second transverse bar. The first and second longitudinal bars each have a contact surface adapted to abut the roof surface, and an opposite upper side. The first and second transverse bars are arranged on, and abut, the upper side of the first and second longitudinal bars. This means that the roof rack can easily be placed over the flange during mounting to the roof surface.
    According to an aspect of the invention, the roof part and the working part are arranged at an angle, and fixed to each other during said power transmission via the first and the second coupling part.
    BRIEF DESCRIPTION OF THE DRAWINGS With reference to the accompanying figures, the invention will be described in more detail, wherein; Figure 1 shows a roof rack according to an embodiment of the present invention after mounting to a roof; figure 2 shows the roof rack from figure 1 in perspective view; figure 3 shows the roof rack from figure 1 with a side view and; figures 4a ~ 4b show parts of the roof rack from figure 1 and the function of the coupling device. PG182XXSE00 4 DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS Figure 1 shows a roof rack 10 according to the present invention on which a worker can sit while working. The roof rack 10 is specifically adapted to be connected to an upright flange 11, also called rebates, which are commonly found on sheet metal roofs. The flange 11 extends from a roof surface 12 and joins two sheet metal parts on the sheet metal roof.
    The roof rack gives a worker a comfortable working position, which spares joints and knees for the worker, but can also function as a relief surface for tools or materials.
    Figure 2 shows the roof rack 10 which comprises a roof part 20 and a working part 50.
    The roof part has a first and a second transverse bar 21, 22, a first and a second longitudinal bar 23, 24 which are substantially rectangular in their cross-sections.
    However, the cross-sections may be square, circular or have another suitable shape.
    The first and the second longitudinal rod 23, 24 each have a contact surface 25, an upper side 26 and an inner and outer side 27, 28. The contact surface 25 is adapted to abut against the roof surface 12 during assembly. The first and second transverse rod 21, 22 abuts the upper side 26 of the first and second longitudinal bars 23, 24 and connects them to form the roof part 10. The roof flange 11 can thus run freely under the first and second transverse bars 21, 22. The flange 11 has a first and a second side 13, 14. The first side 13 of the flange faces the first longitudinal bar 23 and the second side 14 of the flange faces the second longitudinal bar 24 of the roof portion 20 after mounting, as shown in Figure 2.
    The roof part 10 has a coupling device 30 which is arranged to releasably connect the roof rack to the flange 11. The roof rack 10 is mainly attached to a flange 11, but it is conceivable that there are a plurality of coupling devices which attach to the same or to other flanges on the roof surface 12. The coupling device 30 comprises a first and a second coupling part 31, 32. The coupling parts 31, 32 are rotatably arranged to the roof part 20. In cases where only one coupling part is described, it is within the scope of the invention that both the second coupling part 32 also have similar features, which can be seen in figure 2. The first coupling part 31 is articulated to the first longitudinal rod 23 on the roof part 20 via a first and a second coupling rod 33a, 33b. The first and second coupling rods 33a, 33b are hingedly arranged both to the first longitudinal rod 23 and the coupling part 31 so that the coupling part 31 can be rotated without the angle of the contact surface 34 of the coupling part being appreciably changed. The contact surface 34 of the coupling part 31 is thus substantially parallel but the inner side 28 of the first longitudinal rod 23. In the same way the second coupling part 32 is articulated to the second longitudinal rod 24 of the roof part 20. via a first and a second coupling rod 35a, 36b. The first and second coupling rod 35a, 35b are hingedly arranged both to the second longitudinal rod 24 and the coupling part 33 so that the coupling part 32 can be rotated without changing the angle of the contact surface 37 of the coupling part. The contact surface 37 of the coupling part 32 is thus substantially parallel but the inner side 28 of the second longitudinal rod 24.
    The first and second coupling part 31, 32 each have a substantially elongate shape and, as mentioned, have a contact surface 34, 37 which is intended to abut against the first and second side 13, 14 of the flange 11. The contact surfaces 34, 37 are preferably made of a rubber material such as natural rubber or synthetic rubber. Preferably, a friction-increasing material is used as the contact surface 34, 37. The contact surfaces 34, 37 are preferably substantially flat between the transverse ends. The contact surfaces 34, 37 have an area of 5-40 cm 2, preferably 5-30 cm 2, preferably 8 25 cm 2. Between the first and the second coupling part 31, 32, a spring is advantageously arranged (not shown). The spring acts on the first and the second coupling part 31, 32 so that they are pulled towards each other. Alternatively, a spring may be arranged between the first coupling part 31 and the first longitudinal rod 23, and a spring may be arranged between the second coupling part 32 and the second longitudinal rod 24 so that the first and the second coupling part 31, 32 are pulled towards each other. Alternatively, the spring may be arranged to the first transverse rod 21. Instead of a spring, a contracting device, eg an elastic element, may be used, such as a rubber band or the like.
    The working part 50 has a working surface 51. The working surface 51 can be used for setting tools on, standing on, or otherwise connecting other working positions. In the embodiment shown in figure 2, the arloet part 50 consists of a board with about 0.1-0.4 m2, preferably about 020.3 m2. The working part 50 has a substantially rectangular framework 52 to which a disc 53, which forms the working surface 51, of e.g. wood is arranged. A framework 52 also forms a step 54 in that the disc 53 is arranged at a distance from ..._. - ..._._ | ._1__ lf fl 1 ...: ..__. & -.-__ I _ PP lälIlVÜlKÜlb OZ. LVälgäÜ / 'IIUB KISIIIL OC). PG182xxSE00 6 At least one adjusting rod 60, 61 for adjusting and / or fixing the angle d between the roof part 20 and the working part 50 extends between the roof part 20 and the working surface 50.
    The embodiment of Figure 2 shows a first and a second adjusting rod 60, 61 with which the angle oi can be adjusted by changing the length of the first and the second adjusting rod 60, 61. Preferably, the angle can be adjusted so that the working part 50 with its working surface 51 is substantially horizontal. It should be noted that the working part 50, with the working surface 51, is fixed to the roof part 20 after assembly and after the angle has been adjusted to the desired value.
    The force transmission which takes place via the coupling device 30 operates in full despite the fact that the working part 50, with the working surface 51, is fixed to the roof part 20.
    Figure 3 shows the roof rack 10 with a side view. Specifically, the flange 11 is shown which extends from the roof surface 12. On the roof surface 12 rests the roof part 20. The short side of the first and the second transverse rod 21, 22 can be seen lying on the upper side 26 of the second longitudinal rod 24 so that they extend over the flange 11.
    The function of the coupling device will be described below. When the roof rack 10 has been laid on the roof surface 12 and the coupling device 30 has been connected to the flange 11, the coupling part 30 tilts the roof rack to the flange 11 so that the position of the roof rack on the roof surface 12 is maintained. The roof rack acts with a force mg, illustrated by the arrow mg which illustrates the mass times the gravity in figure 3. The force mg can be made to be strengthened by applying a weight to the work surface 51, e.g. by a worker standing on the work surface 51. The force mg together with the roof surface 12 acts on the roof rack 10 with a force P, which wants to move the roof rack 10 in the direction of the force P, i.e. down the roof due to of the slope of the roof.
    Figures 4a ~ 4b show how the force P acts on the roof part 20. For the sake of clarity, certain parts have been removed from the roof rack 10. When the force F acts on the roof part 20, a movement is transmitted to the coupling device 30, unless the coupling device is already engaged with the flange 11, e.g. . via an astringent device as mentioned above. The downward force F in turn gives rise to two inwardly directed forces P1, P2, which press the contact surfaces 34, 37 on the first and the second coupling part 31, 32 against the first and the second side 13, 14 on the flange 11. The forces P1 P2 are parallel to the roof surface 12 and therefore transmit the downward force P in a very good manner and without PG182xxSEO0 7 As noted in Figure 4a, the first coupling part 31 is rotatably coupled to the first longitudinal rod 23 and the second coupling part 32. rotatably coupled to the second longitudinal rod 24. In one embodiment if the coupling parts 31, 32 are coupled to the first and second longitudinal rod 23, 24 at only one pivot point, then the distance between that pivot point and the first transverse rod 21 of the roof part 20 less than the distance between the first transverse bar 21 on the roof part 20 and the pivot point on the coupling part. In the embodiment shown in Figures 4a-4b, the coupling parts 31, 32 are arranged to the first and the second longitudinal rod 23, 24 via the coupling rods 33a, 33b, 35a, 35b via each a first and a second pivot point 71, 72. The first and the the second coupling part 31, 32 are connected to the coupling rods 33a, 33b, 35a, 35b via a third and a fourth pivot point 73, 74. In this embodiment the distance between the first transverse rod 21 on the roof part 20 and the first and the second pivot point 71 , 72 less than the distance between the first transverse bar 21 on the roof part 20 and the third and the fourth pivot point 73, 74.
    The above-mentioned distances are indicated in Figure 4b with broken lines.
    The length of the first connecting rods 33a, 35a together is longer than the length of the first transverse rod 21 of the roof part 20. The length of the second connecting rods 3310, 35lo together is longer than the length of the first transverse rod 21 of the roof part 20. This gives a power transmission to the flange 11 which keeps the roof rack in place. In practice, it is very difficult to release the coupling device 30 by pressure through high load without any material breaking or breaking.
