Abstract

The present invention relates to a mounting system for exterior and interior cladding systems, specifically for interior cladding systems, which allows for a reduced gap between the mounted panels, and a reduced wall-to-panel-distance, which mounting system can universally be used for the "start" panel, the "middle" panel(s) and the "end" panel, and preferably also angled mounting problems.

Description

  • The present invention relates to a mounting system for exterior and interior cladding systems, specifically for interior cladding systems, which allows for a reduced gap between the mounted panels, and a reduced wall-to-panel-distance, which mounting system can universally be used for the "start" panel, the "middle" panel(s) and the "end" panel, and preferably also angled mounting arrangements.
    • Problem with known attachment systems
  • Typical façade cladding systems in the past were made from hot pressed resin/fiber laminates (HPL material) which were relatively thick, and thus heavy. For this reason, they were predominately used for exterior and not interior applications. In recent years new types of facade cladding systems were developed, which are based on lightweight aluminum cover sheets and a non-combustible mineral or mineral polymer core. Compared to HPL panels the aluminum-based panels are considerably thinner and light weighed, so that they can also be used for interior applications. Yet, since typical mounting systems for cladding panels have been developed for exterior cladding systems these mounting systems are less suited for interior applications because the gap between the mounted panels is between about 10 to 20 mm, which is unattractive for interior applications. Moreover, the wall-to-panel-distance with these known "exterior mounting systems" is very high (> 30 mm) so that the interior living space is excessively reduced which is economically unattractive. Another disadvantage with known mounting systems is that three different mounting systems must be provided for the "start" panel, the "middle" panel(s) and the "end" panel; even more and - beyond that - other systems are needed when the panels are mounted on angled walls.
    • Object of the present invention
  • It was, therefore, an object of the present invention to provide a mounting system
    • which can be used for exterior (withstanding high wind resistance) as well as interior (exhibiting thin system thickness) cladding systems, specifically for interior cladding systems
    • which allows for a reduced gap between the mounted panels, preferably with a gap distance of <10 mm, more preferred ≤ 8 mm and most preferred ≤ 6 mm; especially for interior applications the gap preferably has a distance of ≤ 5 mm, more preferred of ≤ 3 mm and most preferred between 1 and 2 mm;
    • with a wall-to-panel-distance of ≤ 30 mm, preferably ≤ 25 mm and more preferred ≤ 20 mm;
    • which can universally be used for the "start" panel, the "middle" panel(s) and the "end" panel, and preferably angled mounting problems (one system for all mounting tasks).
    Solution
  • The above problems are solved with a mounting system which is a combination of joined U-shaped profiles, comprising
    • 2 U-shaped profiles U1 and U2 each consisting of a straight base B and two straight legs L1 and L2, wherein the two U-shaped profiles are attached to each other by the joint straight base B and
    • a straight link attached to one straight leg L1 or L2 of U2, and
    • a further U-shaped profile U3 attached to the end of the straight link, which is not attached to L1 or L2 of U2, such that the two U-shaped profiles U2 and U3 are facing each other with their U-openings like mirror images, and
    • at least one of
      1. a) a further U-shaped profile U4 attached to U3 by the joint straight base with U3, so that the U-openings of U3 and U4 point in 180° opposite directions; (see Fig. 2b);
      2. b) a further U-shaped profile U4 attached to the straight base B of U3 via one of U4's straight legs L1 or L2 so that the U-openings of U3 and U4 point in directions, which form an angle of 90° (see Fig. 2a).

    Definition of terms
  • According to the present invention a "U-shaped profile" is the three-dimensional extension in z-direction of the two-dimensional (x-y-direction) shape of the letter "U" in a Cartesian coordinate system (see Fig. 1). A Cartesian coordinate system for a three-dimensional space consists of an ordered triplet of lines (the axes) x, y and z that go through a common point (the origin), and are pair-wise perpendicular. The two-dimensional (x-y-direction) shape of the letter "U" consists of a straight base (B), having a length "lB" and a thickness "tB", wherein the base has a straight leg attached at each end of the base (L1 and L2), having a length "lL1" and "lL2" and a thickness "tL1" and "tL2". Each of the (inner) angles α1 and α2 between the base and L1 and/or L2 is - independent from one another - 90°±10°, preferably ±5°, more preferred ±2° and most preferred ±0°.
  • "U-opening" is the open side of the U-shaped profile, which is located opposite of the base (B).
  • The three-dimensional extension in z-direction, i.e. the profile depth in the mounting systems (1) according to the present invention is typically between 10 mm and 200 mm, preferably between 15 mm and 150 mm, more preferred between 20 mm and 100 mm.
  • The thickness tB, tL1 and tL2 is - independent from one another - between 0.5 mm and 5.0 mm, preferably between 0.8 mm and 3.0 mm, more preferred between 1.0 mm and 2.0 mm. Preferably, the thicknesses of tB, tL1 and tL2 are about identical.
  • The length of the straight base (B) "lB" depends on the thickness of the cladding system and is typically in the range of from 2 mm to 20 mm, preferably from 3 mm to 15 mm and more preferred from 3 mm to 6 mm.
  • The length of the straight legs L1 and L2 "lL1" and "lL2" are - independently from one another in the range of from 5 mm to 50 mm, preferably from 7 mm to 25 mm and more preferred from 8 mm to 15 mm.
  • The straight link, which joins the two back to back combined U's U1 and U2 with U3 determines the gap between the panels (2) and is typically 10 mm to 60 mm, preferably from 15 mm to 40 mm and more preferred from 18 mm to 22 mm long.
  • The topography of the surface of the straight legs may be even, i.e. not showing any elevations, or it may exhibit a wave-like structure or several elevations with peak to valley distances from 0.1 mm to 0.5 mm, preferably from 0,2-0,4 mm, more preferred from 0,2-0,3 mm.
  • The mounting system (1) may further exhibit guiding rails for Fixation means such as a rivet (3) or nail eventually in combination with a washer (4).
  • The material of the mounting system (1) is not critical and can be a plastic material like polypropylene, polyamide or a metal such as aluminum, iron or the like.
  • The mounting system (1) can be manufactured by known methods e.g. by mold casting, 3D printing or sinter technology to name just a few.
    • Advantages of the mounting system according to the invention
  • Figure 3 shows an exemplary mounting system (1) of the present invention (with two panels (2) mounted).The conventional way to install a panel (2) with known mounting systems is easy, but require an about 15 mm space to slide the edge of each panel (2) inside. The solution according to the present invention is different: slots on the back of the panel (2) allow for an installation from top to bottom. As a result, there is almost no visible gap (see Fig. 5 right); literally, the gap can be reduced to 0 mm.
  • For a vertical layout, usually prior art systems use a small screw and a washer (4) to support the panel (2) at the bottom. However, this screw and washer (4) can only be assembled at a workshop on a bench with a vise. The present mounting system (1) can use a cheaper and easier solution using e.g. a black lacquered rivet (3); the assembly can be made at building site (see Fig. 9).
  • For the "start" panel (2) (see Fig. 6), the "middle" panel(s)(2) and the "end" panel (2) (see Fig. 7), the mounting system (1a) according to the present invention can easily be adapted by cutting the profile accordingly (see Fig. 4).
  • The system can also be used for angled wall cladding (see Fig. 8).
