  • An increasing with increasing tension of the leg spring spring force counteracts the effect that decreases with increasing deflection of the support arm of the storm spring, the proportion of the spring force, which acts in the direction of the roof surface.
  • the acting in the direction of the roof surface portion of the tangential acting along the circular arc spring force decreases with increasing deflection angle of an effective support arm relative to the roof surface according to the cosine function.
  • the effective holding arm refers to the distance between the breakpoint and the axis of rotation of the leg spring.
  • the storm spring according to the invention has the advantage that when a hard Sturmbö acting elastically, it allows a movement, a "opening up" of the roof tile.
  • Very strong, hard winds or storms that are suitable would be to destroy a roof construction, can be taken over spring-mounted roof tiles such their tips that destruction of the roof structure is avoidable.
  • a resulting at the top of the pan vacuum can be reduced by lifting the roof tile.
  • the corresponding energy of Sturmbö is at least partially absorbed initially by the torsion springs and subsequently used to retract the roof tile in position.
  • the distance by which the roof tile can be raised is additionally limited by the length of the holding device in the sense of a safety function, so that even under extreme exhaustive conditions a holding function of the storm spring is provided.
  • the storm spring is designed such that, in an elastic operation, it allows spring-mounted lifting of the roof pan relative to the roof batten up to a maximum predefinable lifting height.
  • the storm spring according to the invention has the advantage that over a predeterminable Anstell Scheme the leg spring approximately the same pressure provides the opportunity to use the same storm spring for roof tiles of different heights universal or at least partially universal.
  • the storm spring is designed such that upon connection of a roof tile with a roof batten the torque acting on the arm is directed around so that a portion of the spring force, which acts parallel to the roof surface, is directed upward, in the direction of a ridge.
  • This configuration complicates a gravitational slippage of the roof tile and allows to hold the roof tile with the help of the spring force in position or return this.
  • the leg spring with the clamping device is connected such that in the connection of the clamping device with the roof batten, the winding of the leg spring can be arranged laterally in front of a transverse side of the roof batten.
  • an arrangement of the winding in front of the upper transverse side of the roof batten offers the mechanical advantage that a leg can be shortened for bridging a projection of a roofing pan to be secured below, resting on the roof batten.
  • this embodiment has the advantage that the storm spring does not penetrate into the space below the roof battens, so that it can be used for the arrangement of films or insulation.
  • connection of the leg spring with the clamping device is resilient.
  • Such a configuration has the advantage that the leg spring can be resiliently removed from the clamping device in a clamping of the storm spring on a batten, so that the leg spring is not obstructive during assembly. Thus, the installation of the storm spring is facilitated.
  • the storm spring is designed such that a voltage of the connected by means of the clamping device with a batten storm spring leads to a pressure of the leg spring against a transverse side of the roof batten, or that the leg spring connected by means of the clamping device with a roof batten storm spring by a voltage of Leg spring is pressed against a transverse side of the roof batten.
  • This embodiment has the advantage that an additional frictional connection between the storm spring and the roof batten is created by a tensioning of the storm spring.
  • a common in the prior art clamping device is U-shaped and adapted to be laterally pushed onto a rectangular roof batten and to clamp the batten of a maximum of three sides.
  • a resilient connection of such a clamping device with a leg spring is executable such that the winding of the leg spring against the fourth, not enclosed by the clamping device side of a rectangular batten is pressed.
  • this embodiment has the advantage that the storm spring on an additional page, in the case of a rectangular roof batten from four sides with the roof batten is connectable.
  • this embodiment has the advantage that over the resulting pressure point between leg spring and batten, the torque of the leg spring is well derivable on the roof batten.
  • a direct contact between the winding of the leg spring and the batten reduces the distance between the pivot point of the leg spring and the batten to the shortest possible distance.
  • the derivation of the torque is not only about the leg arm, but also on the outside of the winding. The winding is pressed against the batten and thus the storm spring additionally secured against slipping sideways or breaking. Due to the direct contact of the winding and batten, an abutment is formed, which has a stabilizing effect on the arrangement.
  • this embodiment has the advantage that by a bias of the spring-loaded connection between the clamping device and leg spring, a four-sided fixation of the storm spring on the batten without a voltage of the storm spring is possible. It thus allows the locking of the storm spring on the batten without the connection with a roof tile. Thus, the risk that the storm spring falls during assembly or disassembly work due to lack of tension in a roof construction or to the ground, can be significantly reduced.
  • the winding of the storm spring is advantageously pressed against the upper half of the transverse side, wherein the upper half of the roof batten half is called, which faces a roof covering or the roof tile.
  • the upper half of the transverse side of the roof batten thus denotes half of the transverse side, which faces the roof tile.
  • the holding device has an engagement device.
  • the engagement device is designed such that it allows the engagement of a tool to clamp the holding device against the torque of the leg spring can. It thus enables a release of the connection between the storm spring and the roof tile, so that, for example, the roof tile can be removed.

If the angle between the effective holding arm and the roof surface reaches a value of 90 °, a maximum height deflection of the storm spring is achieved.
  • the leg spring has more than one turn, in particular, for example, 1.75 or more turns.
  • Such a configuration has the advantage that the spring characteristics of the entire storm spring including the clamping and the holding device are mainly determined by the spring characteristics of the leg spring. It also offers the advantage that the spring constant is tunable so that over a predeterminable angle range similarly strong pressure forces act on a roof tile and the storm spring is thus suitable for roof tiles of different thickness.

  • the upper end of the tilting portion 31 is in the engagement 5, which has a hook in the form of a downwardly open bow.
  • FIG. 8 Furthermore, a clamping device 3 can be seen wherein the, the clamping device 2 out of the plane of the drawing out U-shaped and is adapted to be laterally pushed onto a transverse side of a rectangular roof batten 22.
  • the storm spring 1 "" has an abutment in the form of the winding 17 of a leg spring 4, through which the storm spring 1 "" a batten 22 on the side not enclosed by the clamping device 3 can be pressed.
  • the storm spring 1 "" is completely executed by a spring wire and contactable via one contact point 33, 34, 35, 36, each with a side of a rectangular roof batten 22.
  • One of the contact points 33, 34, 35, 36 namely contact point 33, points to a parallel to the roof batten 22 aligned coordinate axis, that is, along one of the direction 32 aligned coordinate axis, opposite two of the other contact points 34, 35, 36, for example, the contact points 34 and 35, a negative offset.
  • the clamping device 3 is designed such that the first longitudinal leg 7 of the U-shaped clamping device 3 spans a surface 37 for partial support on the upper longitudinal side of a roof batten 22.
  • the surface 37 is oriented on the first longitudinal limb 7 such that it comes to lie approximately parallel to the upper longitudinal side of a roof lath 22 in the mounted state of the storm spring 1 "".
  • the surface 37 is realized by an additional lateral bending of a spring wire end of the clamping device 3 in the form of a triangle. Furthermore, the surface 37 is formed to have a curve in the direction of the opening of the U-shape. In addition, the profile of the surface 37 at its edge has a rounding, since it is formed by a curved wire with a round profile. By a further bend, the surface 37 is almost closed. A remaining opening 38 corresponds approximately to the strength of the spring wire.
  • FIG. 9 shows a schematic drawing of the fifth embodiment of the invention in a perspective view, from which the position of the contact points 33. 34, 35, 36 is better visible.
  • the angle 10 between the surface 37 and the transverse leg 9 has an amount of 88 degrees.
