Definitions

• the present invention relates to a modular system for a building facade comprising polygonal modules with glass panels and/or nontransparent plate panels retained in mounted, interconnected frame members preferably consisting of metal or plastic profiles.
• Such modular systems which may comprise both openable window modules and fixed glass panels or nontransparent plate panels, are known in many different designs from EP published patent applications Nos. 0301166, 0334071, 0395040, 0431230 and 045137, DE patent publication No. 3540385, FR published patent application No. 2649441 and US patent publication No. 3527010.
• the common feature of the known designs is partly that usually they are limited to the use of uniform, rec ⁇ tangular modules, partly that relatively complicated frame structures, often with a considerable number of individual components, are required for the fastening of the panels to the building structure.
• the object of the invention is to provide a design of a modular system of the type indicated having a considerably increased flexibility and degree of liberty in the facade design.
• the modular system accord ⁇ ing to the invention is characterized in that said stationary modules are only connected with the building structure by the fastening of two substantially opposite frame members to supporting elements at or through a facade opening.
• the modular system according to the invention renders it possible to use polygonal modules of differ- ent shapes, such as triangular, trapezoidal or rhombic modules, in addition to conventional, rectangular modules.
• polygonal modules of differ- ent shapes such as triangular, trapezoidal or rhombic modules
• the horizontal facade lines may be displaced in the direction of height between the individual bays, and considerable architec ⁇ tonic liberty is achieved to design the facade with horizontally broken lines.
• the invention also opens up for architectonically more exciting facade designs with gable portions in which typically the upper part will be composed of triangular and/or trapezoidal modular elements.
• substantially opposite frame members should not be understood restrictively as parallel frame members, as the frame members connected with the building structure could well form, for example, the cathetus and the hypotenuse of a right-angled triangle.
• the connection of the modules with the building structure only at said opposite frame members also provides an advantageous possibility of adjusting the individual modules and equalizing any differences in tolerance in connection with the installation.
• said opposite frame members and fastening profiles in connection with said supporting elements are formed with engagement members for engagement with a mounting profile which is provided with locking elements for retention of the frame members and the fastening profiles in secure mutual engagement
• a specially easy-to-mount design in connection with such an adjustment possibility can thus be obtained by forming the mounting profiles for snap engagement with the frame members and the fastening profiles and temporary retention thereof in mutual engagement, which permits adjustment of the modular element before actuation of the locking elements.
• a design of the frame members suitable for indus- trial manufacture can be obtained in that at their interior side edge the frame members have an engagement flange having a cross-sectionally claw-shaped hook portion for engagement with a corresponding cross- sectionally claw-shaped hook portion on a first engage- ment member of the mounting profile, while a second engagement member of the mounting profile is formed with a groove which, when the mounting profile is turned about an axis determined by the engagement between said hook portions can be brought into engagement with a projecting nose portion on the fastening profile, that a sealing profile with a resilient edge part facing the frame member is arranged between the fastening profile and the frame member, and that the locking elements comprise fixation screws mounted in the mounting profile for screwing into a groove positioned behind the nose portion of the fastening profile, after the groove in the second engagement member of the mounting profile has been brought into engagement with the nose portion.
• frame members in this design can be formed with a uniform profile cross-section, for example as extruded, hollow aluminium or plastic profiles
• the adjoining frame members of neighbouring modular elements, for rectangular modules may be interconnected by a resilient sealing profile, and these sealing profiles may be formed with engagement members for engagement with the engagement flanges of the frame members, which flanges are used on the vertical frame members for the above temporary engagement with a mounting profi1e.
• the modular system may comprise at least one openable module with a substantially rectangular panel retained in a pivotal frame consisting of vertical and horizontal frame members, each of which, in the closed position of the module, adjoins a frame member of an adjacent fixed module, of which a horizontal frame member may be fastened to the adjoining horizontal frame member of a fixed module by means of a locking device, while each of the vertical frame members via at least one swinging arm is pivotally connected with a fastening profile associated with the adjoining vertical frame member of the fixed module.

• the facade design shown in Fig. 1 represents the simplest embodiment of a modular system according to the invention and comprises a number of fixed, rectangular modular elements or panels 1, which may each comprise either a sealed insulating glass unit with several layers of glass or a nontransparent plate element.
• the modular elements 1 are shown having a uniform size and shape. This, however, is not at all necessary, as the point of the invention is that it renders possible the use of rectangular modular elements 1 of different heights, but preferably of a uniform width.
• the facade design may comprise polygonal modules of a non-rectangular shape, such as triangular, trapezoidal or rhombic modules.
• the modular elements 1 designed as sealed insulat ⁇ ing glass units or nontransparent plate elements are manufactured in a factory with mounted frame members 2, which, in addition to ensuring better manufacturing and installation conditions and control possibilities, also results in an advantageous protection of the modular elements all the way from the place of manufacture until installation has taken place at the final installation site.
• the modular elements 1 are fastened only at the vertical sides to vertical supporting elements, which may be either free-standing through-going column elements 3 specially designed for the modular system according to the invention, or be load-bearing columns in the building structure.
• the sectional view of Fig. 2 shows a specially designed horizontal main frame profile 4 for connection with the lowest horizontal frame members on modular elements 1 which are to be placed at the bottom in a facade opening against a load-bearing structural element, usually a storey partition.
• the main frame profile 4 is anchored to the storey partition, not shown, by means of anchor bolts, not shown, the position of which is indicated by the dashed- and-dotted line 5.
• the vertical and horizontal frame members 2, which may be assembled around the sealed insulating glass unit or nontransparent plate element of the modular element 1 are formed as a relatively flat, for example extruded, hollow aluminium or plastic profile, in which a track 6 for receiving the sealed insulating glass unit or the plate element 7 is delimited by upright profile portions 8 and 9 for abutment with the sealed insulating glass unit or the plate element 7 on the exterior and the interior sides thereof, respectively.
• a relatively narrow groove 10 is formed for receiving a resilient weather strip, not shown, of an elastomeric material and intended for abutment with a corresponding, also not shown weather strip arranged in a relatively narrow groove 12 formed in the top of an exterior profile portion 13 of the main frame profile 4, which can also be formed as an extruded aluminium or plastic profile.
• a weather strip 14 serves to seal against the profile portion 9 at the inside of the frame member 2 and is connected with the main frame profile 4 through a snap engagement strip 15 formed with two downwards projecting hook flanges 16 and 17 for snap engagement with corresponding hook-shaped flange parts 18 and 19 on an upwardly projecting part 20 of the main frame profile 4, in which a track 21 is further formed to receive a backwards facing bead part 22 of the weather strip 14 at the snap engagement.
• the snap engage ⁇ ment strip 15 is held in place without the use of screws.
• a spring clip 23 having a substantially U-shaped engagement member 24 arranged in engagement with hook edges 25, 26 at a U-shaped track 27 formed to this end and serving as a drainage channel, is arranged in the main frame profile 4 and has a backwards projecting spring leg 28, which rests against a downwards project ⁇ ing edge 29 on the profile portion 9 of the frame member 2.

• the column 30 is connected with a fastening profile 32 by means of a screw or bolt connection, not shown, marked by the dashed-and-dotted line 31, and this profile and each of the vertical frame members 2 are formed with engagement members to engage with a mounting profile 33 which is provided with locking elements for retention of the frame members 2 in secure engagement with the fastening profile 32.
• the frame members 2 within the profile portion 9 are formed with an engagement flange 34 having a claw-shaped hook portion 35, and at one end the mounting profile 33 has a first engagement member 36 with a corresponding claw-shaped hook portion 37.
• the side of the fastening profile 32 facing outwards is formed with a track 38 for engagement with two projecting flap members 39 on a sealing profile 40 arranged between the fastening profile 32 and the frame members 2 and having a basis 41 in contact with the outer side of the fastening profile 32 and two resilient legs or edge parts 42, 43 for contact with the engage ⁇ ment flanges 34 on the two neighbouring frame members 2.
• the track 38 is delimited by two projecting flange parts 44, 45 which also form a projecting nose portion 46 at their interior side facing away from the sealing profile 40.
• the mounting profile 33 For engagement with this nose portion 46, the mounting profile 33 has a second engagement member 47 with a groove 48.
• the first engagement member 36 with the hook portion 37 of the mounting profile 33 is brought into engagement with the hook portion 35 on the engagement flange 34 of the frame member 2 in question.
• the groove 48 at the second engagement member 47 may now be brought into snap engagement with the nose portion 46 on the fastening profile 32.
• the establishment of this snap engagement along the vertical frame members of a module ensures temporary retention of modules, which renders possible an adjustment before the final fasten ⁇ ing.
• the mounting profile 33 comprises locking elements which, in the embodiment shown, are constituted by fixation screws 49 which, after estab ⁇ lishment of said snap engagement between the groove 48 and the nose portion 46 and a possible subsequent adjustment of the module, are screwed into a groove 50 formed in the fastening profile behind the nose portion 46.
• the mounting profile 33 comprises a third engagement member in the form of an inwardly directed nose portion 51 which, by tightening of the fixation screws 49, is brought into engagement behind a corresponding outwardly oriented nose portion 52 of a sideways projecting engagement flange 53 on the fastening profile 32.
• This engagement ensures a controllably uniform gasket pressure between the frame members 2 and the fastening profile 32 at the tighten ⁇ ing.
• the fastening and mounting profiles 32, 33 may be made as extruded metal or plastic profiles.
• both the fastening profile 32 and the sealing profile 40 arranged between the fastening profile and the frame members 2 in neighbouring modules are formed symmetrically, and as mentioned, the fastening profile 32 is formed as a special profile for fastening to a vertical supporting element in the form of a load-bearing column 30 in the building structure itself.
• the sectional view of Fig. 4 shows the fastening of a vertical frame member 2 to a vertical main frame profile 4.
• the fastening profile is here formed as an integral part of the main frame profile 4, the flange portion 45 with the nose portion 46 and the engagement flange 53 with the nose portion 52 in the design of Fig.
