  • This may be a fixed roof, but in modern residential building there is an increasing demand for opening roofs, for example sliding flat roofs, i.e. roofs in which the surface runs almost horizontally without a slope.
  • the roof filling of an openable roof may for example consist of a rollable tarpaulin, lamellae which rotate around their axis, or segments which can slide over each other.

  • the end of the second body is bent so that at least part of the second body extends back in the direction of the front panel wall of the second panel.
  • the two bodies could also be regarded as one continuous body with one or more bends.
  • the connection element ( 220 ) comprises a first body which extends laterally rearward from the rear panel wall of the first panel ( 201 ). Squarely on the end of the first body is a downwardly pointing second body.
  • the downwardly pointing second body is partially curved in order to form a step-like surface with a structure which corresponds to the surface of the complementary connection point ( 225 ).
  • the end of the second body is bent so that at least part of the second body extends back in the direction of the rear panel wall of the first panel. This form ensures that, on a downward movement of the first panel ( 201 ) onto the second panel ( 202 ), the connection element ( 220 ) can engage on the connection point ( 225 ) in order to connect the two coupled panels ( 201 , 202 ).
  • the first panel ( 201 ) furthermore comprises a stiffening element ( 290 ) comprising an upwardly pointing body which extends laterally from the rear panel wall of the first panel ( 201 ).
  • the stiffening element ( 290 ) is connected to the connection element ( 220 ), in particular by a front part of the body of the connection element ( 220 ) which extends rearward from the rear panel wall of the first panel ( 201 ).
  • the stiffening element ( 290 ) stands perpendicularly relative to the top face of the first panel ( 201 ).

  • the stiffening element ( 290 ) which is arranged on or above the connection element ( 220 ) protrudes above the top surface of the first panel ( 201 ).
  • the stiffening element which extends upward on the top of the panel increases the surface moment of inertia of the cross-section of the connection element and the panel, since a large part of the surface of the cross-section of the stiffening element ( 290 ) lies at a greater distance from the center of gravity of the assembly of the connection element ( 220 ) and the stiffening element ( 290 ), in particular in the height direction of the first panel ( 201 ).
  • said assembly can offer better resistance to flexion, in particular in the height direction which is the direction in which the greatest load can be expected, for example loads from the influence of a layer of snow, wind load etc.
  • the stiffening element extends approximately vertically upward, or in other words approximately transversely relative to the almost horizontal top surface of the first panel ( 201 ), since in this manner the distance of the surface of the cross-section of the stiffening element ( 290 ) relative to the center of gravity is maximized, or the surface moment of inertia and resistance to flexion are maximized.
  • Approximately vertically and/or approximately transversely here means a deviation of maximum+/ ⁇ 10°, preferably a deviation of maximum+/ ⁇ 5°, preferably a deviation of +/ ⁇ 3° relative to the vertical or transverse direction.
  • the height of this stiffening element ( 290 ) or in other words the distance by which the stiffening element ( 290 ) protrudes above the top surface of the first panel ( 201 ), or in yet other words the length of the stiffening element ( 209 ) in the vertical direction, is selected so as to give an increased flexion resistance of the assembly formed by the stiffening element ( 290 ) and the connection element ( 220 ).
  • the height of the stiffening element ( 290 ) is greater than the thickness of the first panel ( 201 ), preferably 150% or more of the thickness of the first panel ( 201 ).

  • the stiffening element ( 290 ) can support the second panel ( 202 ), and loads on the surface of the roof device can be spread over the plurality of coupled panels. It is however clear that embodiments of the stiffening element ( 290 ) as described above, for example with reference to the first panel ( 201 ) and the adjacent panel ( 220 ), may also be applicable to more than one such panel ( 201 ) of a roof device, preferably even to each panel of such a roof device, more particularly to each movable panel of such a roof device.

  • the connection element ( 220 ) can couple rollably with the connection point ( 225 ).
  • this roller bearing ( 235 ) comes into contact with an end of the connection point ( 225 ) of the second panel ( 202 ), whereby the body of the connection point ( 225 ) can roll over the roller bearing ( 235 ).
  • the roller bearing ( 235 ) prevents friction between the bodies of the connection element ( 220 ) and the connection point ( 225 ), and thereby improves the coupling/decoupling.
  • the clip ( 230 ) or the roller bearing ( 235 ) which is attached to an end of the connection element ( 220 ) is configured so as, during coupling, to come into contact with an end of the connection point ( 225 ) of the adjacent panel ( 200 ) and limit the friction between the connecting element ( 220 ) and the connection point ( 225 ).
