    HEAT SHIELD FOR SLIDING GATES AND SLIDING GATE INCLUDING SUCH HEAT SHIELD
    This invention relates to a heat shield for shielding a lower guide beam from a sliding gate of incident solar heat.
    This invention also relates to a sliding gate which is provided with such a heat shield.
    Guide bars of sliding gates are guided when opening and closing these sliding gates relative to fixedly arranged guide elements of this sliding gate.
    When sunlight falls on the lower guide bar of a sliding gate, there is a danger that it will warp. This problem occurs, for example, at cold ambient temperatures of, for example, about -10 ° C, in which one side of this guide beam assumes the temperature of the environment, while the afternoon sun warms up the other side of this guide beam to a much higher temperature. Due to the large temperature difference between both sides of this guide beam, it starts to warp. This warping can then form a hindrance for guiding this guide beam relative to the fixedly arranged guide elements of the sliding gate. Such sliding gates are also usually provided with sensors that detect whether there are any obstacles in the opening of the sliding gate when it is closed, wherein the closing of the sliding gate is stopped in the presence of obstacles. A warped guide bar can come in line with these sensors when the sliding gate is closed, so that closing is stopped. In the worst case, the warping of the bottom bar will therefore prevent the sliding gate from opening and / or closing.
    The problem of warping a guide bar of a sliding gate occurs primarily at the lower guide bars. The lower guide beam is usually provided with an opening at the bottom, which means that sunlight falling on this guide beam is less easily spread over the entire guide beam. The upper guide bar of a sliding gate is usually smaller than the lower guide bar and is also usually rectangular in shape, with sunlight incident on this upper guide bar being better distributed over this upper guide bar and no such large temperature difference occurring over this guide bar.
    To prevent warping of guide beams from sliding gates, a guide beam in which the danger of warping is real can be provided with thermal interruptions in the structure of the guide beam itself. This solution against warping of a guide beam is, however, an expensive solution. Moreover, the problem of warping the guide bar only occurs with a relatively small number of the sliding gates produced. In most cases, such a large temperature difference will never be able to occur in the guide beam that leads to warping. Sliding gates are not always positioned in such a way that incident sunlight acts directly on the guide beam. These sliding gates are often placed in the shade of trees, for example. It is therefore undesirable to provide these thermal breaks in the guide beams during production, since this is an expensive adjustment, which is certainly not desirable where this problem of warping would not occur. Where this problem does occur, it is not only quite expensive, but also rather cumbersome and labor-intensive to provide these guide beams with thermal interruptions.
    Attempts were made to provide the lower guide bar with a special infrared reflective coating as a heat shield against solar heat incident on the sliding gate. However, such an infrared-reflecting coating does not appear to offer a satisfactory solution to the said problem of warping of the bottom beam.
    The object of this invention is therefore to provide a simpler to fix and cheaper solution that resolves the warping of the lower guide bar of a sliding gate in such a way that problems can no longer occur when opening and / or closing the sliding gate.
    This object of the invention is achieved by providing a heat shield for shielding a lower guiding beam from a sliding gate of incident solar heat, said heat shield comprising one or more profiles that can be attached to the lower guiding beam such that these profiles are mounted when mounted. extend at least partially on top of the guide beam and extend at least partially next to a longitudinal side of the guide beam, such that these profiles in mounted state are slidable at least in longitudinal direction with respect to the guide beam and such that in the mounted state of these profiles there is a space between these profiles and the guide bar.
    The space between these profiles and the lower guide beam here provides an additional buffer, which prevents solar heat incident on the heat shield, which nevertheless warms this heat shield slightly, from being directed to the guide beam and also heating it up. The profiles must be mounted so as to be slidable relative to the guide beam, in order to compensate for the difference in expansion between these profiles and the lower guide beam. Under the influence of the incident solar heat, the profiles will mainly expand in the longitudinal direction.
    Such a heat shield can be realized in several ways. The guide beam can for instance be provided with fastening strips, in which one or more profile is included as a heat shield, an air layer being present between the profiles and the lower guide beam. Preferably, these one or more profiles then consist of plastic or another low heat-absorbing material. It is also possible to fasten one or more profiles to the lower guide beam with the aid of bolts, wherein, for example, longitudinal slots are provided in the profiles through which the bolts are arranged to mount the profiles slidably with respect to the lower guide beam. A multitude of other fixing methods are conceivable for fixing profiles as heat shield slidable relative to the lower guide beam on this guide beam.
    However, such a heat shield is preferably realized in such a way that each of the profiles is provided with one or more magnetic elements for magnetically fixing these profiles to said guide beam.
    A guide beam of a sliding gate in which the above problem of warping of the guide beam occurs is made of metal. Magnetic elements which are arranged on such a guide beam will therefore also magnetically couple to this guide beam. If this guide beam is not made of a ferromagnetic material, it can just as well be provided with magnetic elements corresponding to the magnetic elements of the heat shield.
    A major advantage of such a heat shield that is magnetically attachable is that, thanks to the simple attachment with the aid of magnets, the guide beam does not have to be adapted to attach the heat shield to it. The production of sliding gates should therefore not be adjusted for those cases where this problem may occur.
    The aforementioned possibilities for providing such a heat shield with the aid of fixing strips, or bolts, etc. each require an adaptation of the lower guide bar. Such an adjustment is not desirable in production, since it is more costly and aesthetically undesirable, where no such heat shield will be placed. Where such a heat shield is desired, these adjustments to the lower guide bar must also be made after production.
    A further advantage of a heat shield that can be attached to the lower guide bar with the aid of magnetic elements is that a layman can also easily and quickly attach this heat shield, so that no high adjustment costs of a sliding gate occur. Such a profile can also easily be sent to sliding gates that have already been placed and where the problem of warping of a guide beam arises.
    The one or more magnetic elements of a heat shield according to the present invention are preferably permanent magnets.
    Each of the profiles is furthermore preferably provided with one or more spacers that are located between the profiles and the guide beam in the mounted state of the profiles, in order to realize the said space. Individual spacers can be arranged on this profile for this.
    In a special embodiment of a heat shield according to the present invention, the magnetic elements are designed as spacers. If the magnetic elements do not serve as spacers, the magnetic elements can then be mounted on a corresponding spacer according to another special embodiment of a heat shield according to the present invention.
    Such a spacer is preferably attached to the corresponding profile by means of an adhesive strip. The magnetic elements are also preferably attached by means of an adhesive strip either directly to the corresponding profile or to the corresponding spacers. With the aid of such adhesive strips, these spacers and magnetic elements can be simply and quickly attached to the corresponding profiles. However, these spacers and these magnetic elements could also be attached to the corresponding profiles in any other way.
    Furthermore, each of the profiles of a heat shield according to the present invention is preferably a substantially L-shaped profile.
    In a preferred embodiment of a heat shield according to the present invention, each of the profiles comprises a first and a second side, the first side being of less width than the second side, the first side being adapted to at least fit in the mounted state of the profile. partially on top of the guide beam and wherein the second side is adapted to extend at least partially next to said longitudinal side of the guide beam in the mounted state of the profile.
    Above the lower guide bar of a sliding gate, fill-in elements are usually provided, which at least partially fill in the space between this lower guide bar and the upper guide bar. At the height of these fill-in elements, the guide beam is less susceptible to incident solar heat. The first side of such profiles can then be arranged at least partially on top of the guide beam in addition to these fill-in elements and will thereby shield the largest percentage of solar heat incident on top of the guide beam. The second side, which is arranged at least partially next to the said longitudinal side of the guide beam, is preferably wider than the first side, in order to be able to shield sufficient incident solar heat over the height of the lower guide beam.
    Per profile with said first and second side, the one or more magnetic elements then preferably comprise at least four magnets, each of which is mounted on a different end of one of the sides of this profile. Alternatively, for example, magnetic strips could be provided which extend over a certain length of the sides of the profile.
    The profiles of a heat shield according to the present invention are furthermore preferably provided with thermal insulation material which, when mounted, fills the said space at least partially.
    The one or more profiles of a heat shield according to the present invention are further preferably manufactured from plastic.
    In a specific embodiment of a heat shield according to the present invention, the one or more profiles are substantially light-impermeable.
    Furthermore, the one or more profiles can be more specifically essentially infrared reflective.
    A further specific embodiment of a heat shield according to the present invention comprises two or more said profiles which at least partially overlap each other in the mounted state. When the profiles are expanded under the influence of incident solar heat, these profiles will then preferably continue to partially overlap each other, so that the external design of the sliding gate remains virtually unchanged.
    The object of this invention is also achieved by providing a sliding gate which comprises one or more of the heat shields according to the invention described above.
    The present invention will now be explained in more detail with reference to the following detailed description of a preferred embodiment of a heat shield and a sliding gate according to the present invention. The purpose of this description is to give only illustrative examples and to indicate further advantages and details of this heat shield and sliding gate, and thus cannot be interpreted as limiting the scope of the invention or the patent rights claimed in the claims. .
    In this detailed description reference is made to the accompanying drawings by reference numerals, in which - Figure 1 shows a sliding gate in perspective; figure 2 shows a detail of the bottom beam of a sliding gate according to the present invention, on which a heat shield according to the present invention is arranged, is shown in perspective; figure 3 shows a profile of a heat shield according to the present invention in perspective; figure 4 shows the profile of figure 3 in front view; figure 5 shows the profile of figure 3 in side view; figure 6 shows a detail of the side view of figure 5 at the height of a magnet.
    Figure 1 shows a cantilevered sliding gate (1) which comprises two roller blocks (12) and a frame movable with respect to these roller blocks (12), which comprises a lower and an upper guide bar (2, 10), between these guide bars (2, 10) fill-in elements (11) are provided. Such sliding gates (1) are often provided with openings of walls, fences, etc. to close entrances and / or exits. The frame of such sliding gates (1) can shift in the horizontal direction relative to the roller blocks (12), as a result of which these sliding gates (1) release or close these entrances and / or exits. These roller blocks (12) are guide elements of the sliding gates (1) which are fixedly arranged. When the lower guide bar (2) is warped under the influence of sunlight incident on it, it will be more difficult or even no longer shiftable with respect to the roller blocks (1) or will slide in front of the sensors which are provided to detect obstacles during closing the sliding gate (1), or will it not completely close the opening, etc.
    To prevent this lower guide bar (2) from warping, it can be provided with a heat shield (3) according to the present invention as shown in Figure 2.
    This heat shield (3) comprises two substantially L-shaped profiles (4). Such an L-shaped profile (4) was shown separately in Figures 3 to 6.
    This L-shaped profile (4) comprises a first side (7) and a second side (8). The first side (7) is of less width than the second side (8). This first side (7) is adapted to be arranged at least partially on top of the lower guide bar (2) and next to the fill-in elements (11) of this sliding gate (1), as can be seen in figure 2. The second side (8) is adapted to be attached at least partially to the corresponding longitudinal side of the lower guide bar (2), as can also be seen in figure 2.
    This L-shaped profile (4) is preferably substantially light-impermeable and substantially infrared-reflecting and is preferably made from a slightly heat-absorbing material, such as, for example, plastic. In this way, this profile (4) can ensure that as little solar heat as possible can reach the screened part of the lower profile beam (2), whereby heating of this lower guide beam (2) is greatly reduced under the influence of incident sunlight. In order to make this profile (4) substantially light-impermeable, it can be made of a light-transmitting material, or it can be provided with a substantially light-impermeable coating. In order for this profile (4) to be substantially infrared-reflecting, this can also be provided with an infrared-reflective coating. In any case, for aesthetic reasons, this profile (4) is preferably finished corresponding to the finish of the sliding gate (1). To this end, this profile (4) can for instance be provided with a coating in the same RAL color as the sliding gate (1).
    In order to be able to attach this L-shaped profile (4) to the lower guide beam (2), this L-shaped profile (4) is provided with four permanent magnets (5), each on a different end of one of the sides ( 7, 8) of this profile (4) are attached, as can be clearly seen in figure 3. In this way this profile (4) can easily be magnetically attached to the lower guide bar (2).
    This profile (4) is further provided here with spacers (6) which, in the mounted condition of the profile (4), are located on the lower guide beam (2) between the profile (4) and the guide beam (2), so as to create space between this profile (4) and this guide bar (2). Thanks to this space, a buffering air layer is provided between the profile (4) and the guide beam (2), so that heat from the profile (4) is guided as little as possible to the lower guide beam (2) as a result of sunlight incident on it. In order to additionally insulate the guide beam (2) from the profile (4), this profile (4) can also be provided with thermal insulation material which, in the mounted state of this profile (4), at least partially fills the said space. Such thermal insulation material was not shown in the figures. Such thermal insulation material can for instance be manufactured from PUR. To provide a heat-buffering layer in addition to the lower guide bar (2), the profile (4) could also be made hollow.
    The magnets (5) themselves can also serve as spacers (6). In the illustrated embodiment, these magnets (5) are arranged on top of the spacers (6), so that an even larger space is created between the profile (4) and the lower guide bar (2). The spacers (6) are attached to the profile (4) with the aid of a double-sided adhesive tape (9). These can also be attached to this in any other suitable way.
    The ideal length of such an L-shaped profile (4) for easy assembly and for production and transport seems to be 1 to 2 m. However, sliding gates (1) are often made longer than 2 m. Two or more such L-shaped profiles can therefore be arranged next to each other or partly overlapping on the lower guide beam (2). If these profiles (4) are arranged next to each other, a sufficient gap between the profiles (4) must be provided in each case, so that they do not interfere with each other in the event of expansion under the influence of incident solar heat.
    A major advantage of such a compact L-shaped profile (4) is that it can easily be sent to sliding gates (1) that have already been placed and where the problem of warping of the lower guide bar (2) occurs. Thanks to the simple attachment with the aid of magnets (5), the lower guide bar (2) does not have to be adjusted to attach the heat shield (3) to it. A layman can easily and quickly attach this heat shield (3).
    Instead of being L-shaped, this profile (4) could also be U-shaped, with the upright sides of the U-shape being arranged above and below the lower guide beam (2). Preferably, only two of the three sides of the U-shaped profile (4) are provided with magnets to provide the necessary clearance for a smooth assembly. In addition, for example, a curved profile (4) could also be used as part of a heat shield (3) according to the present invention.
    In the illustrated embodiment of a heat shield (3) according to the present invention, the profiles (4) of this heat shield (3) are provided with magnets (5) for fixing these profiles at least longitudinally displaceable with respect to the guide beam (2). Thanks to these magnets (5), these profiles (4) are also slidably mounted in other directions relative to the guide beam (2).
    As an alternative to the fixing method with the aid of magnets (5), such profiles (4) can also be provided with the aid of other fixing means on the lower guide beam (2). The lower guide beam (2) can for instance be provided with two fixing strips which are provided at a mutual distance, in which one or more profiles (4) can be received as heat shield (3), by placing them between the fixing strips and behind these hooks on the fastening strips. It is also possible to fix one or more profiles (4) to the lower guide beam (2) with the aid of bolts, wherein for example longitudinal slots are provided in the profiles (4), through which the bolts are arranged, around the profiles ( 4) can be slidably mounted with respect to the lower guide bar (2). Yet another possibility is to provide the profiles (4) with a kind of mounting hooks which can be hooked around vertical fill-in elements (11), as shown in figure 2, to attach the profiles (4) to this. A variety of other fixing methods are conceivable for attaching profiles (4) to this guide beam (2) as a heat shield slidable with respect to the lower guide beam (2).
