    Lamel and its use
    It is known to produce light traps in the form of slats which comprise a longitudinal axis and waves across the longitudinal axis and where there is also a snap connection between a slat and its neighboring slats. The waves across the longitudinal axis ensure that light cannot fall through the space between the slats without having to be reflected multiple times from the surface of the slats, and by making the surface as slightly reflective as possible it is possible to obtain a light trap which allows only a very a small fraction of the light on one side of the light trap to penetrate to the opposite side.
    However, the slats must be kept at a fixed distance from one another and it is advantageous if they can be assembled without the use of tools and so that they are also separable, which allows individual slats to be replaced. Especially when light traps are used in front of ventilation openings, it is important that there is as little flow resistance for air passage through the light trap from one side to the other.
    The object of the invention is to provide a lamella with an integral molded snap connection between the lamella and neighboring lamellae where as little light transmission from one side to the other of a light trap is ensured, while ensuring good snap connection. An alternative to existing slats is also desired to be established with the invention.
    According to the invention, this is achieved by a snap connection in the slat comprising a hole in a slat adapted to receive a projection in a neighboring slat, the projection having two or more opposite snap hooks, a central portion between the snap hooks being formed as a resilient resilient vault.
    This ensures that the movement of the snap-hooks upon insertion of the projection into the
    The 2017 hole has reasonable resistance and at the same time the snap hooks cannot be pulled out of the hole without the vault having to resume their movement. By dimensioning the thickness of the vault, the resistance to the movement of the snap hooks can be predetermined to a desired size, and at the same time the area between the snap hooks will be closed, thus helping to prevent light reflection from one side to the other by a light trap with the lamella i. The snap hooks are squeezed resiliently against each other upon entry into the hole, and snap off when fully bottomed, so that they grip the rim around the hole, thereby being secured against accidentally being pulled out of the hole again.
    It is preferred that both holes and projections are disposed on each side of the plateau projecting in relation to the surface of the slat. It is hereby ensured that when several slats are snapped together in succession, they will sit at a fixed and even distance from one another. At the same time, the raised plateau helps to ensure stability in the transverse direction across the longitudinal direction of the slats when they are snapped together.
    According to an embodiment of the invention, the projection stands out as a spacer between the plateau and the snap hooks, so that the goods around a hole can be received here, with each snap hinge having a through opening in the plateau across the wall thickness, each opening also extending into the spacer. an underside of the associated snap chin. The through-hole opening in the plateau ensures that the snap-hook can be made in a mold without transverse core features, and at the same time allowing the opening to continue along the projection to the underside of the snap-hook ensures that the snap-hook has some movement.
    Advantageously, the length of the spacer between the plateau and the snap hooks corresponds to the thickness around the hole of a protruding plateau in a neighboring lamella to receive a projection. This ensures,
    DK 2017 70424 A1 that the snap function between a slat and a neighboring slat can be established completely without the risk of blurring between the individual collapsed slats.
    The slat appears as a profile having a longitudinal axis and wavy across the longitudinal axis, with each protruding plateau also providing a corresponding recess on an opposite side of the slab such that several slats are stackable as prominent platelets are accommodated in a stacked neighboring slab corresponding thereto. . At the same time, this construction will ensure a uniform thickness across what is, from one side, a raised plateau and from the other side appears as a depression.
    For each projection on a plateau, there is a hole in a plateau at an opposite side of the slat, such pairs of plateau with hole and plateau with protrusion being provided at each end of the slat so that two uniformly formed slats can always be connected in snap with each other via insertion of the projection of one lamella into the hole of the following lamella at each end of the lamellae when one lamella is end-facing with respect to the following lamella. By this construction, it is ensured that the identical slats, when facing the same, can be stacked close to each other, as raised plateaus can be accommodated in the corresponding recesses of the neighboring slats, whereas the slats, when each other is end-facing, can be collapsed at equal distance from each other. In the example, the integrally molded snap joints are used at each end of the slat, but it is possible to insert several pairs of snap joints along the longitudinal axis if necessary for the size of the slats or for stability.
    All prominent plateaus are provided at a first edge and a second edge, respectively, along longitudinal lines parallel to the longitudinal axis of the slat. This detail helps to ensure that the slats are held together where, for example, they are subjected to the greatest load during cleaning with a high-pressure cleaner. In addition, the assembly of the slats along their edges helps to secure the slats against tilting or turning in relation to
    DK 2017 70424 A1 each other, which would otherwise cause greater resistance to flowing air across the longitudinal axis.
    When interlocking a lamella with a uniformly formed end-facing neighboring lamella, both lamellae will have edges extending in each plane, which are parallel and define a front and a parallel rear of a light trap. In this way, by collapsing a plurality of slats, according to the invention, a light trap with flat parallel front and rear sides and good stability is ensured. The light trap can be shipped with the slats tightly stacked so that the shipping volume becomes far less than the volume of a total light trap, and this ensures low shipping costs.
    The invention also relates to the use of slats in a light trap which is mounted in front of a daylight opening in a poultry house for housing. In such an application, it can be ensured that, for example, chickens or chickens are exposed only to the number of light hours per day, which are beneficial for optimizing growth or laying, even if the barn building has large openings against exposed daylight areas to secure it. necessary ventilation for the animals in the stable.
    When using the lamella, it is located in a series of lamellae that are all the same, each other lamella being end-facing and where each lamella is clipped or snap-connected to at least one neighbor lamella and where also a frame is clamped together around the row of slats and mounted in front of an opening against daylight in the poultry house. The light trap, which forms the row of slats, can be placed externally or internally in the stable according to conditions, and it will be extremely easy to clean by high pressure flushing, so that accumulated dust and feather coatings can be easily removed to ensure minimum flow -resistance.
    The invention will now be explained in more detail with reference to the drawings, in which:
    DK 2017 70424 A1
    FIG. 1 shows a front view of a light trap
    FIG. 2 is the light trap of FIG. 1 shown in horizontal section along the line AA in FIG. 1
    FIG. 3 is the light trap of FIG. 1 is a vertical sectional view taken along the line BB of FIG. 1
    FIG. 4 and FIG. 4a shows a close-up view in section through a 3d rendering of 3 slats,
    FIG. 5 and FIG. Fig. 5a shows a 3d view of a prominent plateau with a snap chin seen from the back,
    FIG. 6 and FIG. 6a is a front view of a projection with a snap hook on a plateau (7);
    FIG. 7 and FIG. 7a shows a sectional view in the horizontal plane through the snap connections for three connected slats and
    FIG. 8 is a 3d rendering of a facade section of a stable building with mounted light traps.
    FIG. 1 shows a collection of slats 1 which are retained in a frame 22 so as to form together a light trap 19, the slats 1 all, as seen in FIG. 2, are corrugated across their longitudinal axis 12. The frame 22 and associated slats can then be positioned with a side towards an opening against daylight and a side facing the interior of a barn building. This allows ventilation across the slats, while the daylight due to the waveform of the slats and light absorbing surfaces is prevented from entering the housing building 21.
    In the sectional view of FIG. 3, the longitudinal axis 12 is seen throughout its length, and 8 integrally molded snap joints 2 are visible, with four plateaus 7 pointing out of the plane of the image towards the front lamella, and 4 facing into the plane of the image as recesses 14 and adhering to an underlying lamella. It is noted that since the slat is plate-shaped, a raised plateau 7 on one side will always appear as a recess 14 on the opposite side of the same slat 1.
    DK 2017 70424 A1
    In FIG. 4, the projection 4 is seen and the two snap hooks 5 are most clearly shown in FIG. 5 and 6. A projection 4 comprises the spacer 8, snap hooks 5 and the arch 6 therebetween. The snap hooks 5 are opposite each other and a central portion between them is constituted by a resilient resilient vault 6. In the illustrated example of the invention, the vault 6 curves outward, but it can be made correspondingly curving inward. The vault 6 may be spherical as shown but with greater or less radius so that it more or less protrudes over the snap hooks 5 in the direction of the projection away was the slat, or it may be another form of vault composed of a plurality of planes. The vault 6 should be fully molded, thereby ensuring that the portion between the snap hooks 6 becomes completely impervious to light. However, the vault 6 may well be molded with less thickness than the rest of the slab 1, the flexibility of the vault 6 being hereby adjustable to the desired.
    The two snap hooks 5 have edges, for example, as follows, which follow a circular stroke having the center of the same longitudinal axis of the projection on which the spherical vault 6 has a center. At the same time, the snap hooks 5, in the axial direction of the projection, have conically shaped surfaces so that, together with the arch, they have an arrow-shaped cross-section. This assists in their penetration into the hole 3 of the adjacent lamina's plateau 7, to which they are to be inserted by interlocking lamina 1 with a neighbor lamella 10.
    As seen in FIG. 5, the area under each snap hook 5 is cored so that there is an aperture 9 which pierces the plateau 7 and is contiguous with an aperture in the protrusion spacer 8 below the snap hook 5. This, on the one hand, ensures that the snap hooks 5 have the necessary flexibility. and, on the other hand, it helps to avoid significant accumulations of material which could otherwise give rise to long cooling times for the injection molding operation, thereby producing the slats. Further, the opening 9 in the plateau 7 provides assurance that the snap hook 5 can
    DK 2017 70424 A1 is formed without applying core features to the injection molding tool to form the slats 1. It is noted that when the projection 4 is inserted into a hole 3 in an adjacent slat, the plateau 7 around this hole 3 will cover the opening 9, thus that there is no light transmission through the opening 9.
    In FIG. 4, it can be seen that the raised plates 7 on which the projection 4 and the hole 3 are provided define the distance between the individual slats 1; 10 when snapped at each other. The platforms 7 are connected to the slat 1 via tapered skirts 23 connecting the integrally molded snap joints 2 to the plane of the slat 1.
    The distance between the plateau 7 and the underside 11 of the snap hook 5 is the same as the thickness of an opposing plateau 7 around its hole.
    3. Typically, a thickness of material which is the same for the entire workpiece is chosen, as this will help to optimize the process time, but if a reinforced bond in the snap joint is desired, the thickness of the goods around the hole 3 and the length of the spacer 8 can be adjusted.
    Each slat 1; 10 includes one or more waves across its longitudinal axis as seen in FIG. 7, and to ensure a stable connection between the collapsed slats, there is snap connection on both sides, close to the first rim 13 and the second rim 15 of the slab, respectively, and at a suitable distance from each other along the longitudinal axis. In the cross section shown in FIG. 3 it is seen that there are snap connections 2 at each end of the slat 1.
    The snap joints are in pairs, with at a projection 4 and associated raised plateau 7 there will be a recess 14 with associated hole 3. This means that when the slats 1, as shown in FIG. 4 is aligned with each other slab end-facing, the raised plateau 7 with the projection may be snapped against the recess 14 of the following lamina 10 with hole 3, and the same lamella recess 14 with the hole may be snapped against the projection 4 of a preceding lamella.
    DK 2017 70424 A1
    The first ledge 13 and the second ledge 15 define a plane, and by the end turn here is meant a rotation of 180 degrees about an axis perpendicular to this plane.
    Thus, the raised plateaus 7 on a slat 1 will have projections 4 on one side and on the other side show holes 3, and the slabs belonging to a slat 1 form two parallel planes (not shown), the movement for establishing the snap connection being perpendicular on these plans. Hereby, the slat 1 can be pressed against a neighboring slat 10 without being deformed by collapsing a slat 1 against an end-facing neighboring slat 10.
    The cross section shown in FIG. 7 across the longitudinal axis shows the section through 3 lamellae, a middle lamella 1 being intersected with two neighboring lamella 10. As mentioned, the lamellae are quite similar, but the lamella 1 is inverted relative to the neighboring lamellae 10.
    As seen in FIG. 3, all prominent platens 7 are provided at the first and second edges 13; 15 and further, these lie along longitudinal lines parallel to the longitudinal axis of the slats such that the slats 1; 10 by interlocking with their edges 13,15 each form its own plane 17; 18, which here will constitute the front and back of a light trap.
    As seen in FIG. 1, an outer frame 22 is established around the collapsed slats, which holds the slats 1 together and gives the structure stability, and also allows suspension of the light trap in front of an opening, for example a ventilation opening for a stable building.
    In FIG. Figure 8 shows part of a facade for a stable building 21, on which a number of light traps 19 are mounted in a row across ventilation openings.

    This ensures that the barn can be ventilated at all times of the day without outside daylight entering the barn, and interferes with the circadian rhythm that is desired for the poultry herd here.
