    FACADE ELEMENT AND MOUNTING RAIL FOR RETROFITTING THEFACADE ELEMENT Technical field The present disclosure relates to a façade element and mounting rail device for retrofitting façade elements.
    Background art Multi-storey buildings can be constructed in a variety of ways. Common to all multi-storey buildings, however, is a façade element. The façade element can be constructedto constitute an integral part of the building as a load bearing component or it may onlyserve as a weather protective layer. There may of cause also be different combinationsof façade elements with load bearing properties and weather protective layers. If thefaçade element only is used as a weather protective layer to seal the building then it isusually formed as a plate. In such a case the multi-story building comprises a building structure onto which the plate formed façade elements are attached.
    It is common that the façade elements arrive at the Working site on pallets. These palletsare then off-loaded by a tower crane, a mobile crane, a site hoist or the like and lifted tothe floor of the multi-story building on which they are to be mounted. This step oflifting and installing façade elements is one of the most time consuming tasks when anew multi-storey building is built. Thus, by reducing this time it is possible to reducethe overall time it takes to complete the whole multi-storey building. A furtherdrawback of the conventional construction method is that handling and storage of thefaçade elements occupies space on the construction site. Moreover, unloading, transporting and installation of the façade panels demands a lot of manual labor Brunkeberg Systems AB has developed an efficient method for mounting façadeelements which substantially reduces the time to unload, lift and mount façade elementson a building structure of a multi-storey building. According to the method, which isdisclosed in WO2010070082, façade elements are transported on a conveyer directlyfrom a delivery truck to a multi-storey building. The façade elements are then hoisted by an elevator unit, i.e. a crane, whilst inserted in slots of guiding rails mounted on the building structure, i.e. the vertical edges of the façade element Will run in slots Whilehoisted. This Will make the hoisting procedure less sensitive to Weather conditions, suchas Wind, since the façade elements run steadily in the slots. The guiding-rails aremounted on the building structure all the Way up to the floor that is beneath the floor tobe mounted, i.e. With this method the façade elements are mounted from the bottom andup. When the façade elements have reached the floor on Which they are to be mountedthey are pushed in a horizontal direction towards the building and attached appropriatelyto the building.
    When the façade elements have been mounted onto the building structure for one floor,the interior Work of that floor may start, i.e. equip and decorate the floor. One of thef1nal decorating tasks is to hang curtains and the like. Usually one uses different curtainrods Which are fastened to the façade element. One disadvantage With this procedure isthat it might damage the façade element and Weaken its structural strength. It istherefore common to design façade elements With a security margin due to damagecaused to the façade element When decorating the interior of the building. This Will ofcourse make the façade elements both heavier and more bulky than necessary, Which in the end leads to a more expensive building process.
    Thus, it is an object of the present invention to achieve a façade element Withdimensions that are limited by the conditions that prevail When mounted to the buildingstructure and not by stress that is caused When decorating the interior of the building. Inparticular, it is an object of the present invention to achieve a façade element Withthinner frames than are used today. A further object of the present invention is toachieve a mounting rail for engagement With the façade element, Which mounting rail easy may be retrofitted With curtains, illumination etc.
    Summary of the invention According to a first aspect of the present disclosure at least one of these objectsis achieved by a façade element comprising a frame and façade material, Wherein theframe is provided to surround and hold the façade material. An upper part of the façadeelement has a length L, said upper part being provided With a mounting area. An elongate recess With an undercut is extending at least along a major part of the length L of the upper part of the frame, said recess With the undercut being adapted for receiving a mounting rail in a locking engagement.
    The elongate recess of the façade element may according to one embodiment extend along the entire length L of the upper side of the frame.
    According to some embodiments the façade element may be provided With a recess that is substantially L-shaped or a recess that is substantially anchor-shaped.
    According to a second aspect of the present disclosure at least one of these objects isachieved by a mounting rail for retrofitting a façade element. The façade elementcomprises a frame and façade material. The frame is provided to surround and hold thefaçade material. An upper part of the façade element has a length L, said upper partbeing provided With a mounting area. The mounting rail comprises a L-shaped liftingportion, a shoulder and a locking mechanism, Which are adapted to be received by andin locking engagement With an elongate recess of the façade element. The recess isprovided With an undercut and extends at least along a major part of the upper part ofthe frame. The length of the recess corresponds to a length of the mounting rail, suchthat When the mounting rail is in an engaged state the L-shaped lifting portion isinserted in the recess of the frame and the shoulder rests on a surface of the upper part atone side of the recess and the locking mechanism rests on a surface of the upper part at another side of the recess.
    Furthermore, the locking mechanism is pivotable between an open position, in Whichthe mounting rail is insertable into the recess of the frame and a locked position, in Which is the mounting rail is in locking engagement With the recess of the frame.
    According to an exemplary embodiment the locking mechanism is provided With aspring biased locking ball adapted to engage a cavity of the mounting rail, When the locking mechanism is in the locked position.
    Furthermore, the mounting rail may be provided with illumination means and/or with holding means adapted for receiving curtain hangers.
    With such a façade element provided with a recess having an undercut the frame of thefaçade element may be designed with smaller dimensions then is customary, since onenow no longer need to damage the façade element when decorating the interior of the building.
    By using a mounting rail that it inserted into the elongate recess it is possible to retrof1tthe façade element with curtain hangers, illumination and other interior decoration itemswithout having to damage the façade element. Furthermore, the time to fit the mountingrail by “snapping” it into to the recess and tuming the locking mechanism is negligiblecompared to the traditional way to decorate the inside of the building, which requires measuring, drilling, fixing etc.

The invention may, however, be embodied in many differentforms and should not be oonstrued as limited to the embodiments set forth herein.Rather, these embodiments are provided so that this disclo sure will be thorough andcomplete, and will fully convey the scope of the invention to those skilled in the art.
    Thus, the invention is only limited by the appended claims.
    Figure 1 shows a schematic view of an exemplary embodiment of a façade element 2.The façade element 2 oomprises, a reoess 10, a frame 12, façade material 14, an upperpart 16, and a reinforoement frame 18. The main components of the façade element 2are the façade material 14, the upper part 16 and the frame 12. The façade material mayby any material suitable used for building multi-story buildings, such as glass, concrete,metal, bricks, insulation etc. The façade element 2 may oomprise one or more façadematerials in different oombinations. Also the upper part 16 of the façade element 2 maybe considered as a façade material or as part of the frame 12. In the exemplaryembodiment of the façade element 2 in figure 1, the façade material comprises glass(windows) 14 and a combination of aluminium and insulation in the upper part 16. Thealuminium/insulation combination oorresponds in this exemplary embodiment to anarea of the ceiling structure of the building, i.e. it will cover and extend below the ceiling structure when mounted to the building structure.
    The façade material 14, 16 is surrounded and held by the frame 12. In the exemplary embodiment disclosed in figure 1, the façade element 2 is further reinforced by a reinforcement post 18. The use of such a reinforcement post 18 is optional and dependson which size the façade element 2 has. As is realized by a person skilled in the art theremay be numerous ways to design reinforcement frame 18 and it is believed to be withinin the capabilities of such a person to design a suitable reinforcement frame taking thedimensions of the façade element into account. However, there may also be otherconsiderations than strength, such as the appearance of a façade element 2, when designing the reinforcement frame.
    The upper part 16 of the façade element 2 is provided with a recess 10 and has a lengthL. The recess 10 is designed and adapted to receive a mounting rail, with help of whichthe façade element 2 may be retrofitted with curtain hangers, illumination etc. Therecess 10 will be closer described in conjunction with figures 2 and 3 and the mountingrail will be closer described in conjunction with figures 4 and 5. The interactionbetween the recess 10 and the mounting rail and how they are brought into a locking engagement is closer described in conjunction with figures 6 to 8.
    Tuming now to Figure 2 an exemplary embodiment of the recess 10 will be described.The recess 10 is provided on the upper part 16 of the frame 12, i.e. a mounting area.Figure 2 shows an enlarged side view of the upper part 16 of the façade element 2. Therecess 10 is provided with an undercut 11, i.e. it has a hollow space under the surface 4of the upper part 13 of the frame 12. The undercut 11 is, in the embodiment of figure 2,defined as being the hollow space that is to the left of an axis X that is perpendicular tothe upper part 16 and running adj acent to the opening of the recess 10. The undercut 11is an important feature when bringing the mounting rail into locking engagement withthe recess 10 as will be explained further below. The shape of the recess 10 as seen in the enlarged side view of figure 2 may be defined as L-shaped or boot-shaped.
    Figure 3 shows another exemplary embodiment of the recess 10. In this embodimentthe recess 10 is provided with two undercuts 11, 11” instead of one. The principles forthe undercut are the same as in figure 2 and will therefore not be described again. Thesecond undercut 11” in figure 3 is a mirror image of the first undercut 11 in figure 2,which gives the recess 10 an anchor-like shape. One advantage with having a recesswith double undercuts is that the mounting rail may be inserted into the recess 10 fromtwo different directs, which may be beneficial during the retrofitting process of the façade elements 2. As is understood by a person skilled in the art the recess 10 may be designed in a Variety of ways. As mentioned above it is import that the recess has anundercut in order to create a locking engagement with the mounting rail. The importantfeature is that the undercut is adapted such as it may receive the mounting rail 20, andespecially the lifting portion 21 of the mounting rail 20. In the described embodimentsthe lifting portion 21 of the mounting rail 20 is shown as L-shaped, but may for examplealso be J -shaped or any other suitable shape adapted for locking engagement with a mating recess 10 having an undercut 11.
    Figure 4 shows a side view of a mounting rail 20 and Figure 5 shows an enlarged sideview of the mounting rail 20. The mounting rail 20 comprises a lifting portion 21, ashoulder 22, illumination 23, locking mechanism 24 and different fastening means 25,27 for different types of curtain hangers and the like. The mounting rail 20 may bemanufactured in aluminium, steel or any other suitable metal or material with themechanical properties for lifting a façade element 2. The illumination may be fitted inbetween two lips. In the example embodiment in figure 4, there is provided fourillumination sources, but this number as understood by a person skilled in art a designoption when designing the mounting rail. The different fastenings means 25, 27 areadapted to receive different type of curtain hangers or other interior decorationselements. In the exemplary embodiment in figure 5 a curtain hanger 28 with a hook isprovided onto which a curtain may be hanged. The hook may be fastened to a rail thatextends the whole length of the mounting rail 20. Typically the mounting rail 20 has thesame length as the length L of the façade element 2, i.e. the width of the façade element2.
    Figures 6 to 8 show enlarged views of different stages of the procedure when themounting rail 20 is brought into locking engagement with the recess 10 of the façadeelement 11. In Figure 6 a first stage of the locking engagement between the mountingrail 20 and the recess 10 is shown. In this stage the mounting rail 20 is angled and the L-shaped lifting portion 21 of the mounting rail 20 is inserted into the recess 10. As soonas the L-shaped lifting portion has been inserted into the recess 10, the mounting rail 21is rotated in the direction of the arrow T into an upright position, i.e. perpendicular tothe surface 4 of the upper part 16 of the frame 12. During this movement the L-shapedlifting portion 21 will slide into the undercut 11.
    In Figure 7 the mounting rail 20 is shown in its upright position. In this position theupper part of the L-shaped recess 10 is almost completely filled out by the L-shapedlifting portion 21. The shoulder 22 of the mounting rail 20 is designed such that it abutsthe surface 4 of the upper part 16 of the frame 12 when the mounting rail 20 has reachedits final upright position. In this position the mounting rail 20 cannot be rotated anymorein the direction of arrow T, since the abutment of the shoulder 22 works as a stopper forthe rotational movement in the direction of arrow T. Also the design of the L-shapedlifting portion 21 of the mounting rail 20 and the undercut 11 of the recess 10 acts as astopper, since the L-shaped lifting portion 21 will abut the surface of the undercut 11when the mounting rail 20 is in its final upright position. Thus, the mounting rail 20 issecurely fixed into recess 10 and may withstand forces applied in the direction of thearrow T. However, if forces are applied in an opposite direction of the arrow T themounting rail 20 will reverse its previous movement and fall out of the recess 10. Toprevent such a movement and securely fix the mounting rail 20 in the upright positionthe mounting rail 20 is provided with a locking mechanism 24. In figure 7 the lockingmechanism 24 is shown in an open position, i.e. the mounting rail 20 has not been securely fixed into the recess 10.
    Tuming now to Figure 8 the locking mechanism 24 is shown in a locked position. Infigure 8, the area of the locking mechanism 24 is also shown in an enlarged view inorder to better understand how the looking mechanism 24 functions. The lockingmechanism 24 may be a block that is pivotally attached to the mounting rail 20. Whenthe locking mechanism 24 is in its closed position one end surface of the lockingmechanism 24 is in abutment with the surface 4 of the upper part 16 of the frame 12. Inthis position the mounting rail 20 is in a locking engagement with the recess 10. In apreferred embodiment the locking mechanism 24 may furtherrnore be provided with aspring-biased ball 26. The spring-biased ball 26 is adapted to interact with a cavity 29provided on the mounting rail 20. The cavity 29, the ball 26 and the spring 28 are bestshown in the enlarged view of figure 8. When the locking mechanism 24 is tumed fromthe open position to the locking position the spring 28 will push the ball 28 into thecavity 29 when the locking mechanism 24 has reached its final position and therebysecurely fix the mounting rail 20 into the recess 10. As realized by a person skilled inthe art there may be many other ways of securing the locking mechanism 24 in itslocking position, such as spring-biased pins, pins and holes or a groove in the mounting rail adapted to receive the locking mechanism when it is in its final position etc. It is of course also possible to provide the spring-biased ball on the mounting rail and the cavity in the locking mechanism instead.
    Even if the steps of engagement between the mounting rail 20 and the recess 10 infigures 6 to 8 relate to a recess having a L-shaped cross section, the steps are of coursealso applicable for the anchor shaped recess shown in figure 3 or any other suitable recess having an undercut.
    Figure 9 and Figure 10 show a partial front view of the mounting rail with the lockingmechanism 24 in is its open and locking position, respectively. The spring biased-ball26 is indicated in the figures by dotted lines, since it is hidden by the lockingmechanism 24 in figures 9 and 10. In figures 9 and 10 the full length of the mountingrail 20 is not show, but only the two ends where the locking mechanisms 24 areprovided. The number of locking mechanisms 24 depends on the length of the mountingrail 20, and is preferably two for a façade element with a width (same as length of upperpart 16) of 3 m. The length of the mounting rail 20 may in a preferred embodimentcorrespond to the length L of upper part 13 of the frame 12. Using the whole length L ofupper side 13 of the frame will make it possible to retrof1t the entire width of the façade elements with curtains, illumination etc.
    Thus, it is believed that different embodiments have been described thoroughly forpurpose of illustration and description. However, the foregoing description is notintended to be exhaustive or to limit example embodiments to the precise formdisclosed. Thus, modifications and variations are possible in light of the aboveteachings or may be acquired from practice of various altematives to the providedembodiments.
