Description

Field of the Invention

[0001] The present invention relates to a roof for outdoor areas such as pergolas, and more particularly to a roof slat and a slatted grid comprising the slat.Background of the Invention

[0002] For outdoor areas such as terraces and atria, there is currently a great interest to cover them, especially for areas with outdoor furniture. The reason is both to protect the furniture from adverse weather conditions such as rain or snow, and to allow sitting outside even in bad weather. This is why different types of roofs have been developed in the form of slatted pergolas, which ventilate and let in light when the slats are open and make a flat roof when closed.

[0003] Document KR 102068117 describes a slat system comprising parallel opaque slats connected at each short end to one of a pair of side bars provided with guide grooves for guiding the slats, further comprising a movable bar located in one side region of the slats to allow movement of the slats along the axis of rotation. A similar solution according to document US 2006 / 0040607 is a pergola roof consisting of parallel slats mounted pivotally on slat hinges supported on carrier beams transverse to the slats. The slats are pivotable between a closed position in which their longitudinal adjacent edges overlap each other and an open position in which the slats are spaced apart. The slat hinges are mounted to the slats at their lower surface, and they allow pivoting of the slats between the closed position and the extreme open position by an angle of at least 90°. Such solutions provide a roof for outdoor areas and protection of outdoor furniture from adverse weather conditions. However, the disadvantage of such solutions is that the slats are only rotatable for roof when they are in a horizontal position, when they do not allow water to pass through, but neither do they allow sunlight. In the open position, the slats are in a vertical position, in which they allow sunlight to pass through, but only partially due to the arrangement of the slats, and rain can also pass through. Furthermore, such a solution does not address the drainage of water from the roof in the closed position.

[0004] The solution described in document CA 3 079 336 partially addresses these disadvantages, as it describes a slatted pergola with supporting columns that bear the frame. On the frame, two fixed opaque slats are arranged at opposite ends, and the space between them is filled with rotatable opaque slats. The opaque slats are pivotable between a closed position in which the rotatable opaque slats partially overlap each other, and an open position in which there is a gap between adjacent opaque slats allowing air to pass through. Each rotatable opaque slat is further equipped with a drainage channel for draining rainwater in the closed position. The disadvantage remains that the slats are only rotatable for roof, where in the closed position they do not allow sunlight to pass through, creating shade to near darkness under the pergola, and in the open position, sunlight partially passes through under the pergola, but rain can also pass through.

[0005] The drainage problem is also addressed by document WO 2016 / 099712, which describes a pergola roof consisting of a set of slats that move between an open upright position and a closed position covering the pergola. Each set of slats has a rotary shaft mounted for rotational movement between parallel cross beams of the pergola. The rotary shaft carries at least one movable slat. The movable slat has the shape of the letter S or the letter J, and at least part of the movable slat overlaps the adjacent slat in the closed position. This shape of the slat allows rainwater drainage along the sides of the pergola, creating a gutter when placed in the horizontal position. The disadvantage is that, in the vertical position, each slat has a larger surface area, and therefore, even less sunlight enters compared to the previous cases.

[0006] Document WO 01 / 12916 describes a louver or slat system comprising a plurality of profiles. Each profile includes a surface portion with an outer surface and fasteners for placing the profiles into grooves, allowing rotation in the grooves to allow sunlight to pass through. The fasteners join the panel members together to form the louver. The individual profiles may be two-component, joined with two adjacent components, one of which may be transparent. The disadvantage of such a solution is that although the slats are two-component, it involves the placement of two components on top of each other in a vertical plane, and thus no sunlight can pass through.

[0007] These disadvantages are partially eliminated in documents WO 2024 / 057160, KR 20170001457 or JP 2003221896, which describe a set of slats, where one slat is made from two profiles: one polycarbonate profile and one aluminium profile, arranged in the same plane, i.e. making an angle of 180° with each other. The aluminium profile according to JP 2003221896 may be further equipped with a solar panel. These documents thus describe an alternating solution to slat profiles connected to each other in the horizontal plane to allow more light to pass through, but they do not provide sufficient shading or sufficient passage of sunlight. For shading, the slats need to be rotated by 90°.

[0008] Currently, the most used slat system for covering outdoor areas consists of opaque slats. Each opaque slat includes a carrier body, which is made of a hollow, flat and elongated profile. The carrier body is further provided with front faces that have pins for guiding the carrier body in the guide grooves of the slat system, thus allowing rotary movement for the closed horizontal position, where neither water nor sunlight passes through. In the open vertical position, sunlight is partially allowed to pass through. This type of slats also has a sliding movement to fully retract the roof to the side, allowing sunlight to pass through completely. However, the disadvantage is that it does not provide the option of combining roofs that prevent water ingress while still allowing sunlight to pass through.

[0009] It is therefore an object of the present invention to provide a roof slat and a slatted grid comprising the slat, which would eliminate the above disadvantages, providing the possibility of roofing outdoor areas both without allowing sunlight to pass through and with allowing sunlight to pass through.Summary of the Invention

[0010] The stated object is achieved by providing a slatted grid for the roof, which includes a carrier body, which is made of a hollow, flat, and elongated profile. The carrier body is provided with front faces that have pins for guiding the carrier body in the guide grooves of the slatted grid. The essence of the invention is that the slatted grid for the roof further includes a transparent wing attached longitudinally to the carrier body along its entire length, making an angle α with the carrier body, ranging from 60° to 120°, preferably 90°. Such a solution provides the possibility of roofing outdoor areas without allowing sunlight to pass through when the carrier bodies of the slats are placed in a horizontal or closed position, where the transparent wing is placed perpendicular to the carrier body above the plane of the roof. This solution also provides the possibility of roofing with allowing sunlight to pass through when the transparent wings are placed in a horizontal or open position, where the carrier body is placed perpendicular to the transparent wing below the plane of the roof.

[0011] For the purposes of the description of the present invention, the term "roof plane" refers to the area of horizontal placement of the carrier bodies or transparent wings of the set of slats that creates the roof for outdoor areas such as a pergola or atrium. It is the area defined by the guide grooves.

[0012] In a preferred embodiment, the carrier body is equipped with a U-shaped base for mounting the transparent wing, which preferably extends along the entire length of the carrier body. Such a solution provides a secure mounting of the transparent wing and prevents it from moving or falling out of the slat structure.

[0013] In another preferred embodiment, the front face is provided with an arm and a handle for mounting and carrying the transparent wing at a distance I from the carrier body. This arrangement allows for secure anchoring of the transparent wing from the sides, preventing the transparent wing from moving in gusty winds.

[0014] In another preferred embodiment, the transparent wing is made of glass, as glass made of transparent materials provides the maximum transmission of sunlight.

[0015] In another preferred embodiment, the base on the side remote from the side for mounting the transparent wing is equipped with a seal for seating the adjacent slat. This arrangement prevents the damage to the carrier body as well as the transparent wing during rapid rotation of the slat system from the open to the closed position.

[0016] In another preferred embodiment, the transparent wing includes a seating surface, which is equipped with a seal for seating the adjacent slat. This arrangement allows for maximum tightening of the transparent wings in the horizontal position for the roof without gaps between individual slats, while the seal prevents both mechanical damage to the transparent wing and ensures the creation of a solid roofing without rainwater ingress under the roof.

[0017] In another preferred embodiment, the carrier body on the edges of the profile is equipped with drip rails, which create a drainage gutter for draining water from the roof.

[0018] The stated object is further achieved by providing a slatted grid system comprising a set of slats. Each slat includes a carrier body, which is made of a hollow, flat and elongated profile. The carrier body is provided with front faces that have pins for guiding the carrier body in the guide grooves of the slat system. The essence of the invention is that the slatted grid includes a set of the slats as described above. In the open position of the slatted grid, the transparent wings of the slats are in a horizontal position, and the transparent wing of the slat is seating on the carrier body of the adjacent slat, with the carrier bodies arranged below the plane of the roof. In the closed position of the slatted grid, the carrier bodies are in a horizontal position, and the drip rails of one slat extend over the drip rails of the adjacent slat to create a solid connection, with the transparent wings arranged above the plane of the roof. This solution provides the possibility of roofing outdoor areas both without allowing sunlight to pass through and with allowing sunlight to pass through.

[0019] The advantages of the roof slat and the slatted grid comprising the slat according to the present invention are mainly that it provides the possibility of roofing outdoor areas both without allowing sunlight to pass through and with allowing sunlight to pass through.Explanation of drawings

[0021] The slatted grid 2 for roofing outdoor spaces consists of a set of rotary slats 1, 1' about an axis, as shown in Figs. 5 to 7. The slat 1, 1' is made in the shape of the letter "L" and includes a carrier body 3 and a transparent wing 6, with the carrier body 3 and the transparent wing 6 making an angle α equal to 90°. This arrangement of the slat 1, 1' is shown in Figs. 1 to 3. In another non-illustrated exemplary embodiment, the carrier body 3 and the transparent wing 6 make an angle α in the range from 60° to 120°.

[0022] The carrier body 3 is made of a hollow, flat, and elongated aluminium profile, as shown in Fig. 4. In another non-illustrated exemplary embodiment, the carrier body 3 is made of another material, such as wood or polycarbonate coated with a dark film. At the ends, the hollow, flat, and elongated profile is provided with front faces 4, 4' made of the same material, which are attached to the profile using screws. In the centre of each front face 4, 4', there is a pin 5, 5' that guides the carrier body 3 in the guide grooves of the slatted grid 2 and allows the slat 1, 1' to rotate. The front face 4, 4' is further provided with an arm 8, 8' and a handle 9, 9', which is made in one piece from a casting for mounting and carrying the transparent wing 6 at a distance I from the carrier body 3. In this embodiment, the distance I is 110 mm, and in another non-illustrated exemplary embodiment, the distance I is in the range from 100 to 130 mm. Such a slat 1, 1' is shown in Figs. 1 and 3. In another non-illustrated exemplary embodiment, the front face 4, 4' is not provided with an arm 8, 8' and / or a handle 9, 9'. The carrier body 3, as shown in Fig. 4, is equipped with drip rails 13, 13' on the edges of the profile. In another non-illustrated exemplary embodiment, the carrier body 3 is not equipped with drip rails 13, 13'.

[0023] The transparent wing 6 is made of glass. In another non-illustrated exemplary embodiment, the transparent wing 6 is made of frosted glass or polycarbonate. The transparent wing 6 is connected to the carrier body 3 at one end by means of a base 7 in the shape of the letter "U", in which the transparent wing 6 is mounted, and which is an integral part of the hollow, flat, and elongated profile of the carrier body 3, as shown in Fig. 4. The base 7 runs along the entire length of the carrier body 3 for secure anchoring of the transparent wing 6, thus preventing water from entering the hollow, flat, and elongated profile. In another non-illustrated exemplary embodiment, the base 7 does not run along the entire length of the carrier body 3. The base 7, on one side fitted with the transparent wing 6 and on the other side provided with a seal 10 for seating the drip rail 13 of the adjacent slat 1' during the rotation of the set of slats 1, 1'. The other end of the transparent wing 6 includes a seating surface 11, on which there is a seal 12 for seating the drip rail 13' of the adjacent slat 1'.

[0024] The set of slats 1, 1' has the possibility of rotational movement in the slatted grid 2 between the open position and the closed position. In the open position, the transparent wings 6, 6' are in the horizontal position, and the transparent wing 6 is seating tightly with the seal 12 on the seating surface 11 against the drip rail 13' of the adjacent slat 1', where the carrier body 3, 3' is placed perpendicular to the transparent wing 6, 6' below the plane of the roof, as shown in Fig. 5. In the closed position, the carrier bodies 3, 3' are in the horizontal position, where the drip rail 13 of the carrier body of one slat 1 is seating on the seal 10 on the base 7 on the side remote from the side for mounting the transparent wing 6' of the adjacent slat 1', and the transparent wing 6, 6' is placed perpendicular to the carrier bodies 3, 3' above the plane of the roof, as shown in Fig. 7.Industrial applicability
