Description

[0001] The invention relates to a bird deterrent device for preventing birds from landing and / or perching, wherein the bird deterrent device has a longitudinal dimension and a bottom surface for mounting the bird deterrent device on an object to be protected. The invention further relates to an object to be protected, such as a wayfinding system and / or a sign.

[0002] Various bird deterrent measures are known to prevent birds from landing, perching, and / or nesting. For example, perches and / or nesting sites can be made inaccessible with wire mesh and / or netting. Furthermore, bird spikes, also called pigeon spikes, are known, consisting of long metal spikes mounted on a strip. The spikes are usually V-shaped and attached to a plastic or stainless steel base. While pigeons and other birds are not usually killed by such a deterrent system, there is a possibility of injury. Magpies, in particular, have learned to remove the metal spikes from the pigeon spikes and use them in their own nests for protection against birds of prey. For these reasons, the use of pigeon spikes as a bird deterrent is not widely accepted.

[0003] The purpose of the invention is to improve the state of the art.

[0004] The problem is solved by a bird deterrent device having the features of claim 1. Further advantageous embodiments of the bird deterrent device are described in the dependent claims. Furthermore, the problem is solved by a wayfinding system and / or sign according to the features of claim 10.

[0005] This provides a bird deterrent device that effectively prevents birds from landing and / or perching, and consequently prevents the deterrent device and the object being protected from being soiled by bird droppings and feather fragments, thus eliminating the need for additional cleaning. Furthermore, it prevents health risks to humans from the transmission of pests and infectious diseases.

[0006] It is particularly advantageous that the bird deterrent device according to the invention, as a purely mechanical and structural measure, provides reliable bird control without harming health and without killing the birds. Furthermore, the installed bird deterrent device requires no special ongoing maintenance and can be attached to an outer surface of the object to be protected using simple tools and / or a simple connection technique.

[0007] A key aspect of the invention is to design the bird deterrent device in cross-section essentially in a triangular basic shape and, by forming the two interior angles together of ≥ 90° between the underside and the two sides of the triangular basic shape, to design the upper point in such a way that it is so acute-angled and / or has a narrow width that birds cannot perch on the upper point and / or the triangular basic shape.

[0008] It should be emphasized that the object to be protected can be any type of object where bird deterrents are necessary or desired. Besides wayfinding systems, signs, and / or displays, for example at a train station or tram stop, the object to be protected can also be a building facade, a balcony, a solar panel, a roller shutter box, a gutter, a bridge, or other structures. In the case of a gutter, it is particularly advantageous that the bird deterrent device covers the entire width and length of the typically open-topped gutter with its underside, thus preventing leaves, needles, and debris from landing in the gutter and therefore reducing cleaning effort.

[0009] The bird deterrent device can be made in one piece and extend the entire length of the object to be protected. However, two or more bird deterrent devices can also be arranged lengthwise, one behind the other and / or side by side, to partially or completely cover the length and / or width of the object to be protected.

[0010] At the upper corner of the triangular base, the triangular shape can transition into two vertically extending, at least partially opposing sections to form part of the upper point. One of these vertically extending sections can be taller than the other, so that the higher, upward-facing edge of the taller section prevents birds from landing and / or perching. This is particularly advantageous if, due to the width of the object to be protected and thus the underside of the bird deterrent device, the upper corner of the triangular base itself is not very acute and therefore only slightly less than 90°.

[0011] By means of a raised section and / or a flat, planar structural element positioned vertically upwards, it is particularly prevented that birds fly towards the bird deterrent device from above and, especially in the case of obtuse-angled and / or irregular triangles as the basic shape, attempt to land on the triangular base itself.

[0012] In principle, the triangular base shape can be an irregular, isosceles, equilateral, acute, right-angled, and / or obtuse triangle. Consequently, the shape and design of the bird deterrent device can be optimally adapted to the object being protected.

[0013] It is important to emphasize that the terms "perpendicular" and "vertically upward-pointing" do not necessarily imply an angle of 90° to the horizontal. Regarding its orientation, the component in question may also have a slightly smaller or larger angle than 90° to the horizontal. For example, a component's orientation can deviate by 90° ± 20°.

[0014] Preferably, at least one vertically oriented, flat component, such as a sheet metal strip, is arranged and / or connected between the two opposing, vertically upward-pointing sections of the triangular base. The sheet metal strip and / or the component can, in particular, be formed in one piece along the entire longitudinal dimension of the bird deterrent device. Likewise, two or more components can be arranged one after the other along the longitudinal dimension. The component need not necessarily be a sheet metal strip and / or a thin, flat sheet. For example, the component can also be slightly curved and / or corrugated.

[0015] To prevent birds from perching on the legs of the triangular base itself, the vertically upward-pointing structural element and / or the higher section of the triangular base can have a significantly greater height than the upper corner of the triangular base.

[0016] Preferably, the triangular base shape is formed from a single sheet of metal, with or without sections that are at least partially opposite each other. The sheet can be any type of metal, such as sign metal. It can be made of aluminum or steel, for example. Preferably, the sheet is an aluminum composite panel, such as Alu Dibond. ®FR. The aluminum composite panel has a material thickness of 3.0 to 6.0 mm. The aluminum composite panel can be designed to be flame-retardant and fire-rated, for example, according to fire protection class D1. The aluminum composite panel can have a polyethylene core and two thin, opposing aluminum cover layers on the opposite surfaces of the panel. To form the triangular shape, the sheet metal and / or the aluminum composite panel can be bent, folded, and / or shaped. In the case of the aluminum composite panel, it can be cut and / or milled at the appropriate locations to form the inner corners of the triangular shape and then bent into the triangular shape. Likewise, the two vertically projecting sections, which are at least partially opposed, can be aligned at their ends by bending.

[0017] Preferably, the vertically oriented component and / or the sheet metal strip has a material thickness that is at least somewhat less than that of the sheet metal and / or the aluminum composite panel. For example, the component and / or the sheet metal strip can have a material thickness in the range of 0.3 to 0.5 mm.

[0018] If the bird deterrent device is made of sheet metal and / or an aluminum composite panel and is therefore a hollow body, the two opposing sides of the bird deterrent device can be open or closed lengthwise. In principle, both sides can be open or closed, or only one side can be closed. The sides can, in turn, be closed by means of sheet metal and / or an aluminum composite panel. Alternatively, each side can be closed in a different way, for example, by means of a plastic cap.

[0019] In principle, the bird deterrent device can have any color and / or surface finish. Preferably, the entire bird deterrent device is RAL 5022 Night Blue.

[0020] The bird deterrent device can be attached to the object to be protected using any connection technique. For example, the bird deterrent device can be screwed and / or glued to the object to be protected.

[0021] The invention will now be explained in more detail using an exemplary embodiment. Figures show... Fig. 1. A three-dimensional representation of a bird deterrent device, and Fig. 2 a sectional view of the bird deterrent device in the area of ​​a blind rivet.

[0022] A bird deterrent device 101, designed as a pigeon deterrent, has a triangular base 103 with a base 105 and two lateral legs 109. The bird deterrent device 101 has a width 64 mm and a length 500 mm at its base 105. At an upper corner 113 of the triangular base 103, it transitions into an upper point 107. The upper point 107 has a right point section 115 and a left point section 117. The two pointed sections 115 and 117, together with the triangular base 103, are formed from an aluminum composite panel. A sheet metal strip 119, designed as a vertically oriented, flat component, is arranged internally between the right point section 115 and the left point section 117. The sheet metal strip 119 extends beyond the height of the two tip sections 115, 117.The sheet metal strip 119 is firmly connected to the two tip sections 115, 117 by means of four blind rivets 123 distributed over the length of the bird deterrent device 101, each with a washer 125 arranged underneath.

[0023] The bird deterrent device 101 is rigidly attached to the upper surface of a guide sign of a wayfinding system (not shown in the figures) and occupies the entire length and width of the guide sign on its upper surface. The bird deterrent device 101 has a total height of 61.8 mm, with the height of the triangular base 103, including the two pointed sections 115 and 117, being 47.2 mm, such that the upper end of the sheet metal strip 119 projects 14.6 mm beyond the upper ends of the two pointed sections 115 and 117. The triangular base 103 and the two pointed sections 115 and 117 have a material thickness of 4.0 mm. The sheet metal strip 119 has a material thickness of 0.4 mm. Due to its narrow upper edge, pigeons and other birds cannot perch on the upper surface of the sheet metal strip 119. Because the respective interior angle 111 between the underside 105 and the respective leg 109 on both sides is 45° ( Fig.2) pigeons and other birds cannot perch directly on the outside of the legs 109 of the triangular base 103, especially since the upper point 107 with the vertically upward-pointing sheet metal strip 119 prevents them from flying up from above.

[0024] Thus, the bird deterrent device 101 with the triangular base shape 103, the upper point 107 and the vertically upward-pointing sheet metal strip 119 achieves effective pigeon and bird deterrence.
