Definitions

  • the present invention is generally related to a retractable screen construction.
  • Outdoor screen constructions e.g. canopies, terrace canopies, pergolas, awnings, gazebos, pavilions, etc.
  • outdoor constructions are currently widespread which use curtains and movable walls constituted substantially by a flexible screen that can be unrolled from a roller (along a predefined direction, be it horizontal, vertical, oblique or curvilinear), in order to protect (upwardly or laterally) a predefined area and/or constitute a hindrance to access from the outside for people, insects and other animals, atmospheric agents, etc.
  • retractable screens are a common accessory of buildings and housings, such as awnings, canopies or terrace canopies, sunscreens, curtains, sun sails, etc.
  • a retractable screen may also provide an enclosed space, for example a tent, a gazebo, etc. Creating portable or non-permanent enclosures or spaces using retractable screens is particularly relevant for outdoor use.
  • Other applications may include retractable screens for protecting solar panels from rain or dust or for efficiently blocking or reducing sunlight exposure through a window.
  • the screen is usually manufactured from a flexible material, for instance fabric (e.g. textiles) or plastics material.
  • the screen may be transparent, partially transparent, or opaque to visible light.
  • Particular types of screens, when closed, may block wind and rain.
  • the materials used for these screens are light weight, which presents some problems for outdoor use. For example, wind may lift and/or bend the screen, thus interrupting the primary function of the screen. In some cases, the screen may become deformed or may even tear or break. This problem is alleviated by including fixed runners which hold the screen in place at the side thereof. However, runners are often insufficient, as the screen may be forced out of the runners by heavy gusts of wind.
  • one end of the screen is usually provided with a draw bar (also called a weight bar) which is guided in screen guide profiles. Due to its weight, the draw bar already tensions the screen. Furthermore, a locking mechanism is usually provided to lock the draw bar in a fixed position with respect to the screen guide beams. Once locked, the screen can be tensioned by partially retracting the screen.
  • a draw bar also called a weight bar
  • a locking mechanism is usually provided to lock the draw bar in a fixed position with respect to the screen guide beams. Once locked, the screen can be tensioned by partially retracting the screen.
  • a known locking mechanism involves providing spring-biased pins on the ends of the draw bar in combination with screen guide profiles provided with one or more catches to catch the pins thereby locking the draw bar in a fixed position.
  • Examples of such a locking system are disclosed in EP 1 785 545 A2 , EP 2 500 508 A1 , EP 3 708 762 and WO 2004/048715 A1 where the catches are defined by means of a complex groove/guide pattern.
  • WO 2016/131085 A1 where a rotatable cylindrical cam member mounted in the screen guide profiles defines various guide paths for a pin fixed on the draw bar.
  • a known issue with these systems is their durability. More specifically, when the screen is rolled-up, the guide paths are exposed to the outside atmosphere. As such, precipitation, dirt, insects, etc. can freely enter the guide paths and cause one or more blockages which may lead to malfunctions. Especially considering that the guide paths are mostly vertically oriented, water flow caused by gravity will, over time, deposit filth therein, which will cause blockages.
  • IT 2018/00007818 A1 proposes to place the guiding paths on the ends of the draw bar and to place a pivotable pin at the bottom end of the screen guide profiles that is then guided through the guiding paths when lowering/raising the draw bar.
  • outside exposure can interfere directly with the pivotable pin thus causing malfunctions.
  • EP 3 670 822 A1 discloses a retractable screen construction according to the preamble of claim 1 which allows, when used with the fixed keeper, the latch bolt to cycle through its various positions to provide for an automatic locking of the draw bar.
  • the latch bolt is retracted.
  • the latch bolt engages an inclined keeper surface thereby depressing the latch bolt (i.e.
  • the latch bolt thus moves from its retracted position to its depressed position and is then moved towards its extended position (i.e. outwards with respect to the draw bar) by a biasing member.
  • the resilient element is now in one of its extreme positions.
  • the latch bolt is caught in the keeper and the draw bar is locked and the screen may be tensioned.
  • the screen is again unrolled so that the latch bolt again contacts the inclined keeper surface thereby depressing the latch bolt to move it from its extended position to its depressed position.
  • the resilient element thus moves to its other extreme position.
  • the latch bolt Upon reversing the screen direction, the latch bolt is again urged outwards. However, the resilient element is then caught in the intermediate position so that the latch is kept in its retracted position and can be moved upwards without remaining caught in the keeper. By cycling through these positions, the draw bar is automatically locked and unlocked with respect to the guide beams without requiring user intervention.
  • the latch mechanism further comprises: a rototranslatable lever on which the latch bolt is pivotally mounted and having two cam members, the rototranslatable lever being slideable along the longitudinal direction and rotatable about a pivot axis perpendicular to the longitudinal direction; and a labyrinth member having a plurality of pathways in which said two cam members are guided, the plurality of pathways defining: at least one inner position for the rototranslatable lever which corresponds to the depressed position of the latch bolt; a rest position for the rototranslatable lever which corresponds to the retracted position of the latch bolt; and an actuated position for the rototranslatable lever which corresponds to the extended position of the latch bolt.
  • the latch bolt can be cyclically moved between three distinct positions (i.e. the depressed position, the retracted position and the extended position).
  • the use of a rototranslatable lever guided in a labyrinth member allows for an accurate and reliable guiding of the rototranslatable lever between three distinct positions without relying on a resilient element. Since the latch bolt is pivotally positioned on the rototranslatable lever, its sliding motion is also accurately and reliably controlled between its depressed, retracted and extended position.
  • the labyrinth member has an open side facing the rototranslatable lever, the open side being directed towards a ground surface.
  • the rototranslatable lever has a closed side opposite the open side. This further reduces the risk of pathway blockages due to water, dirt, insects, etc. More specifically, even should debris be able to enter the draw bar interior, since the labyrinth is mounted upside down (i.e. with is open side facing a ground surface), gravity will aid in removing such debris from the labyrinth member.
  • Providing a closed side is advantageous as this provides an easy way to fix the labyrinth member inside the draw bar as the closed surface can be mounted against an inside wall.
  • the labyrinth member is substantially planar.
  • the use of a planar labyrinth member allows for an easy placement of the labyrinth member in the draw bar, e.g. the closed side may be attached to an inside surface of the draw bar.
  • the labyrinth member is static. Using a static labyrinth member avoids the need for moving parts that modify the pathways during the cyclic displacement of the rototranslatable lever. Such moving parts may be especially problematic for outdoor use.
  • the plurality of pathways extend mainly in the longitudinal direction. This allows to provide a relatively narrow labyrinth member (i.e. one which is longer that it is wide) which allows for an easier placement in the draw bar as this is also an elongated structure.
  • the keeper comprises: an engagement surface for engaging the latch bolt when the retractable screen is being unrolled from said screen roller to slide the latch bolt into its depressed position; and a catch for catching the latch bolt when the latch bolt is in its extended position and the retractable screen is being rolled up said screen roller, the catch being located closer to the cross beam than the engagement surface.
  • the engagement surface causes the automatic depression of the latch bolt when unrolling the screen, while the catch acts as a stop for the latch bolt (and thus the draw bar) when in the extended position.
  • the engagement surface comprises an inclined face. This provides for a gradual automatic depression of the latch bolt.
  • the screen unrolling speed and the inclination angle determine the latch bolt movement speed and thus also the rototranslatable lever movement speed so that this can be optimized to avoid sudden large or fast movements which could lead to malfunctions in the cyclic pathing (e.g. a movement to the wrong position and/or along the wrong pathway).
  • the plurality of pathways comprise: at least one first pathway between the rest position and the at least one inner position; a second pathway between the at least one inner position and the actuated position; and a third pathway between the actuated position and the at least one inner position, the third pathway being different from the second pathway.
  • the plurality of pathways define at least two different inner positions for the rototranslatable lever each corresponding to the depressed position of the latch bolt.
  • the plurality of pathways comprising: a first pathway between the rest position and a first one of said at least two inner positions; a second pathway between the first inner position and the actuated position; a third pathway between the actuated position and a second one of said at least two inner positions; and a fourth pathway between the second inner position and the rest position.
  • Having two different inner positions for the rototranslatable lever means that there are four rototranslatable lever positions thus avoiding that a single inner position has to be used twice during different locking/unlocking actions.
  • Having four distinct pathways linking these four rototranslatable lever positions further avoids having to use a single pathway twice, thereby further reducing possible malfunctions.
  • the labyrinth member comprises: a first catch defining said rest position and configured for catching a first one of said cam members; a first inclined element configured for guiding a second one of said cam members when the latch bolt is slid from its retracted position to its depressed position, the first inclined element causing a rotation of the rototranslatable lever thereby moving said first one of said cam members out of the first catch; a second catch defining said actuated position and configured for catching one of said cam members, said one of said catch member preferably being said first one of said cam members; and a second inclined element configured for guiding the other one of said cam members when the latch bolt is slid from its extended position to its depressed position, the second inclined element causing a rotation of the rototranslatable lever thereby moving said one of said cam members in range of the first catch.
  • the latch bolt and the rototranslatable lever are always urged to a same side of the labyrinth member. Furthermore, having only two catches minimizes the labyrinth design as each may correspond to one of the positions in which the latch bolt must remain for extended periods of time (i.e. the retracted position and the extended position which are both considered stable positions).
  • the inclined elements change the position of the cam members in the direction perpendicular to the longitudinal direction, thereby determining in which catch one of the cam members will be caught when sliding outwards (with respect to the draw bar) in the longitudinal direction.
  • cam member to be in both catches provides an easy design as there is then a catch cam member and a guiding cam member with the catch cam member defining the latch bolt position and the guiding cam member causing latch bolt positional changes. This may also minimize the amount of rotation required of the rototranslatable lever during its cyclical positional chain when compared to an embodiment where one cam member is caught in the first catch and the other one is to be caught in the second catch which may require the rototranslatable lever to have to undergo a full 180° rotation.
  • the second catch fully encompasses the first catch in a direction perpendicular to the longitudinal direction.
  • the first catch has a certain width and the second catch protrudes with respect to the first catch on either side thereof. As such, as of the moment the cam members are outside the width of the first catch, they will be caught in the second catch.
  • each pathway ends in either the first catch or the second catch. This avoids that there are any pathways that would lead to undesired positions, thus improving the robustness of the latch mechanism.
  • the second catch has a width which is about equal to a width of the labyrinth member. There is thus no way for the cam members to extend in a width position beyond the second catch. In other words, one of the cam members will always be caught in the second catch (unless it is caught in the first catch). This improves robustness of the latch mechanism.
  • the latch bolt pivots with respect to the rototranslatable lever about a further pivot axis which corresponds to said pivot axis of the rototranslatable lever.
  • the retractable screen construction further comprises: a motor for driving the retractable screen; and a controller configured to control the motor, the controller being preferably configured to, when a limit movement of the retractable screen is detected, control to motor to reverse a screen movement direction.
  • a motor improves user comfort as there is no need for a user to manually operate the retractable screen. Reversing screen movement direction when a limit movement is detected allows tensioning the retractable screen as the draw bar is locked with respect to the guide beams during (or soon after) the limit movement.
  • the controller can be preprogrammed to reverse screen movement direction to tension the screen. This may however be less accurate and may not take thermal expansion effects into account.
  • a detector is used to detect the screen limit movement.
  • the detector may be a torque sensor which are known in themselves and provide for a reliable detection mechanism.
  • the pivot axis of the rototranslatable lever is parallel to the guide beams.
  • the rototranslatable lever (and the labyrinth) is horizontally positioned. This allows attaching the labyrinth to the top or bottom inside of the draw bar which is easy. This further minimizes space requirements when compared to an inclined labyrinth positioning.
  • the latch bolt is configured to cycle through a positional chain, the chain being: starting in the retracted position, continuing to the depressed position, continuing to the extended position, continuing to the depressed position, and returning to the retracted position.
  • the rototranslatable lever is configured to cycle through a positional chain, the chain being: starting in the rest position, continuing to the at least one inner position, continuing to the actuated position, continuing to the at least one inner position, and returning to the rest position.
  • the positional chain includes both. This, as described above, reduces malfunction risk.
  • both embodiments above in fact have the same advantage, namely of providing a latch mechanism which, when used with a corresponding keeper, can provide an automatic locking and unlocking of the draw bar.
  • the locking assembly is configured to lock a retractable screen draw bar in a fixed position and comprises a fixed keeper and a latch mechanism, the latch mechanism comprising: a latch bolt which is slideable along a longitudinal direction between a depressed position, a retracted position and an extended position, the depressed and extended positions defining two opposite extreme points for a free end of the latch bolt with the free end of the latch bolt being between these opposite extreme positions when the latch bolt is in the retracted position; a biasing member urging the latch bolt towards its extended position; a rototranslatable lever on which the latch bolt is pivotally mounted and having two cam members, the rototranslatable lever being slideable along said longitudinal direction and rotatable about a pivot axis perpendicular to said longitudinal direction; and a labyrinth member having a plurality of pathways in which said two cam members are guided, the plurality of pathways defining: at least one inner
  • the present invention is further directed towards a method of operating the retractable screen construction described above, the method comprising: unrolling the screen; depressing the latch bolt which preferably occurs automatically during the unrolling of the screen; rolling the screen up until the latch bolt is caught in the keeper thereby locking the draw bar, this may particularly further involve tensioning the screen by retracting the screen when the draw bar is locked; and unlocking the draw bar, which unlocking preferably comprises: unrolling the screen; depressing the latch bolt which preferably occurs automatically during the unrolling of the screen; and rolling up the screen.
  • the present invention generally relates to closure and locking of retractable screens, which advantageously provides high resistance against wind while still allowing flexible, lightweight materials to be used, such as polymer, glass fiber, glass cloth, textiles and the like.
  • the locking may be automatic and safe without requiring any user intervention.
  • the present invention may provide automatic locking when the retractable screen is completely deployed (closed), and it can provide automatic release when requested to retract (open).
  • the locking assembly used in the present invention is compact and the required elements can be fitted in a small volume, for example in a draw bar of the retractable screen, which holds the screen and provides tension to the material of the screen at least due to gravity.
  • the retractable screen construction according to the present invention may be highly (or even fully) automated, without the need of programming of controllers or self-learning algorithms.
  • the construction may also be compatible with manual control, for example manual locking of the screen at a predetermined position.
  • present invention is not limited by the actual mechanism of retraction.
  • the present invention may be applied to any type of deployment and retraction of retractable screens, whether the screens are actually wound or folded.
  • the present invention may also be applied to various types of screen, whether it is a textile screen or a screen formed by rigid strips of material connected to each other.
