  • Drainage and sealing system and a panel system comprising such a system
    Patent number: 6647683
    Abstract: In the drainage and sealing system, an external rain shield is designed as a separate flexible sealant strip (38,58,59), and an internal drain trench (44, 64) is provided on a separate drain element (40, 60) extending in parallel to and at a distance from the external sealant strip (38, 58, 59). The drain element (40) and the external sealant strip (38) comprise a flange portion (41, 38b) for releasable securing to a frame member of a panel in the panel system. The separate drain element (40, 60) can be designed as an internal cover strip where the drain trench (44, 64) is provided in an essentially U-shaped portion (43, 63), and where the drain element on the side facing away from the drain trench (44, 64) has a portion (42, 62) for reception of an internal sealant strip (45, 65).

  • Panel system
    Patent number: 6591557
    Abstract: The panel system is meant for construction of a panel fillet or a major panel surface to be mounted in a pitched roof or in a facade, comprising a number of fixed panels (1) together with a number of openable panels (2), each panel comprising a frame structure composed of frame members (13, 22) bordering a panelling element (32) between them, each frame member (13, 22) comprising a profile element (30) and at least a core element (35). The profile elements (30) are designed as uniform standard parts, and in that at least some frame members of the frame structure are provided with means to vary the moment of inertia, where the means can comprise at least one element (47) which is received in said core element (35) and which extend over essentially the entire length of the frame member.

  • Mounting and hinge fitting for a panel and a panel system comprising such fittings
    Patent number: 6487821
    Abstract: The panels (1, 2) are along a frame member connected to one or more support elements (3) in an angle of inclination in relation to a subjacent securing plane by means of mounting and hinge fittings (4) which can be adjusted in dependence of said angle of inclination, the fittings also constituting the hinge fittings of the openable panels. Each fitting (4) comprises a securing part for connection with the support element (3), a hinge part for connection with the frame structure of the panel (1, 2) and an adjustment part connecting the securing part with the hinge part.
