Definitions

  • the invention relates to a snow gun according to the preamble of patent claim 1.
  • Such a snow catch hook is known from the utility model DE 78 00 625 U1.
  • Such snow catch hooks are mounted on a pitched roof to hold snow and ice, so that the departure of a roof avalanche is prevented.
  • the disadvantage of the known snow catch hook is that in a relatively short design, in which the angled support is located near the covered section of the provided with the snow catch roof tile, the force to be dissipated by the support is introduced approximately in the middle of the roof tile, so that the roof tile is exposed to increased breaking load.
  • a better dissipation of the force is achieved if the snow catch hook is carried out so long that the support is located in the area of the overlapping portion of the roof tile, so that the force is transmitted via the underlying covered roof tile on the supporting roof batten.
  • the disadvantage of such a long snow catch hook is that it tends to rattle in the snow-free time in strong wind or storm.
  • a snow guard device which consists of a snow guard nose and an adjoining fastening part (DE 33 03 306 A1). At least the snow guard nose is bent from a strip-shaped metal band. In the area bounded by the snow guard nose, a stiffening insert in the direction of the longitudinal center plane of the snow guard nose is introduced.
  • Another well-known roof snow catcher has a fastening part extending parallel to the roof, provided for snow guard, approximately perpendicular to the fastening part extending catch part and a the upper end of the catching part on the back connecting to the fastening part supporting part (DE 40 09 164 A1).
  • a transverse extending, on both sides over the width of the catching part projecting tentacle is attached.
  • a snow hook for tile roofs is also known in which two different widths formed beads are provided on a mounting strap (CH 457 786, AT 225 102).
  • Object of the present invention is to provide a snow catcher that allows the favorable derivation of the power to the batten back without bending stress of the roof tile, is easy to make and does not rattle in snow-free state even in a storm.
  • the snow catch hook rests hollow in the unloaded state on the roof tile bearing it between hook and support.
  • the snow catch hook When installed on the roof, the snow catch hook is bent flat by the weight of the roof tile covering it, so that the end portion having the support is pressed onto the roof pan bearing the snow catch hook. It has been shown that a force of about 0.15 kp is sufficient to prevent rattling during storms.
  • the snow catch hook is made of elastic material.
  • the snow catch hook can also be installed in the curved watercourse of a profiled roof tile, if the flat material has a portion adjacent to the hook-shaped bent end with a width of less than 20 mm, advantageously less than 17 mm.
  • This narrow section lies in the installed state on the roof in the covered area of the roof tile and lifts the overlapping roof tile very little. If the covered section was made in full width, depending on the profiling of the roof tile used, different embodiments of the snow guard hook would be required, which have an adapted transverse curvature in this section.
  • the angled support can absorb high forces if it has a stiffening, which is essentially triangular in side view and connected in the region of the bend with the snow catch hook.
  • a particularly high stability of the support is achieved by simple means, if additionally stiffening longitudinally extending beads are provided in the region of the support and the stiffening. In the interior of the stiffening triangle may also be provided a plate arranged in the longitudinal direction.
  • the snow catch hook 10 made of flat material has at one end a hook 12 pointing to the underside. At the other end an upwardly angled support 14 is arranged. Between the hook 12 and the support 14, the snow catch hook 10 has an upward curvature 16.
  • the angled support 14 has a stiffening 18 which is substantially triangular in shape and connected in the region of the bend 20 with the snow catch hook 10.
  • Fig. 2 which shows the snow catcher 10 in plan view
  • the snow catcher hook has a portion 22 adjacent to the end with the hook 12 and having a width of less than 20 mm, for example 17 mm.
  • beads 24, 26 are provided in the region of the support 14 and the stiffening 18 extending in the longitudinal direction beads 24, 26.
  • FIG. 3 shows a variant of the snow guard hook according to the invention in a side view.
  • This snow catch hook 30 has at one end again a hook pointing to the bottom, which consists of the mutually perpendicular hook portions 31 and 43.
  • To the hook portion 43 includes a transition piece 44, which communicates with a narrow portion 32 in conjunction, which corresponds to the portion 22 in Fig. 2.
  • a transition section 33 is provided, wherein the boundary between the two sections 42, 34 is characterized by a slight bend 45.
  • the section 42 is followed by a small, oblique section 41, which merges into a section 40.
  • This portion 40 terminates in a curve 39 leading to a snow trapping ridge 38 which is substantially perpendicular to the portion 40.
  • This snow catcher fin terminates in a cap 37 which communicates with an inclined support 36.
  • a section 46 which merges via a rounding 35 in the support 36.
  • the curvature or curvature according to the invention is in this case essentially formed by the sections 32, 33 and 34.
  • FIG. 5 shows two snow guards 50, 60 in a side view, in conjunction with roof tiles 49, 51 to 53, which are mounted with their one side in slats 54 to 57 and with its other end on a snow catch hook or on the rest on the adjacent roof tile.
  • the snow catch hook 60 rests freely on the roof tile 53, ie it is from above not charged.
