Definitions

  • This invention describes a new system for moving the equipment of a retractable roof, where the roof is made up of a number of trusses that move along rails, and with which a tarpaulin or similar surface can be folded or unfolded to cover a facility, such as a sports field, a recreational area, or an outdoor commercial or industrial area.
  • the system that is the subject of this invention corresponds to different types of retractable structures, more specifically to folding roof structures and, in particular, to the means, systems or equipment that make it possible for such roofs to be folded or unfolded.
  • retractable roofs mainly based on telescopic or retractable systems. They involve major construction problems at certain heights, limiting their field of application and preventing the trusses that make up such structures from moving correctly.
  • An example of this type of roof is given in document U.S. Pat. No. 2,603,171. This means that this type of roof has to be designed for each particular facility.
  • retractable tarpaulin systems such as those shown in document ES1054415U or document ES1016096U, which describe mechanisms for folding large tarpaulins, but which are not supported by a structure that provides resistance or durability against rain, wind or other environmental agents.
  • document ES2531203 describes a type of roof composed of a variable number of aligned movable trusses that move on two parallel rails.
  • the trusses are connected to each other by a tarpaulin deployed by the inertia of the first truss, which is set in motion by a motor operated by a remote control or pushbutton.
  • the roof can remain deployed as all the trusses are dragged by the first motor truss, the last truss being immobilised and fixed in position at all times.
  • the problem with this document is that it presents a displacement system that encounters jamming problems caused by weight, and it can also come off the rails, which can affect the safety and strength of the roof assembly.
  • the displacement system of this invention is designed to improve the movement of trusses that support tarpaulins or enclosures, and that constitute a retractable roof.
  • This roof is composed of a variable number of aligned retractable trusses.
  • the trusses move on two parallel guide rails and are joined together by a tarpaulin deployed by the inertia of the first truss, which is set in motion by a motor operated by a remote control or pushbutton, such that the roof can remain deployed as all the trusses are dragged by the first motor truss, the last truss being immobilised and fixed in position at all times.
  • the displacement system of this invention is based on the fact that a runner is coupled to each end of a truss with a number of grooved wheels connected in the form of a bearing by means of bolts, and each runner is connected to a guide rail.
  • the top and bottom faces of the guide rail comprise a curved surface with which the grooved wheels are in contact and along which they run.
  • the runner consists of two side walls facing each other, where a truss post is attached to the inner wall, and at least two grooved wheels are attached between the walls at two heights, the wheels being fixed between the side walls by means of a shaft.
  • a truss post is attached to the inner wall
  • at least two grooved wheels are attached between the walls at two heights, the wheels being fixed between the side walls by means of a shaft.
  • the wheels of the upper row are in contact with the upper curved surface of the rail, while the wheels of the lower row are in contact with the lower curved surface of the rail. In this way, the runner moves and remains in contact with the rail and cannot come off it, as the runner wraps around the rail.
  • the truss stays vertical; it enables smooth movement, ensuring there is no significant resistance when the tarpaulin is pulled to unfold, as it increases the free surface along which it can run. In turn, this improves the durability of the tarpaulin.
  • the system also enables safe movement without the tarpaulin coming out of the guide rail, as the rail is sandwiched between the two wheel heights and the side walls of the runner. There is also an improvement in the weight distribution of each truss and the tarpaulin in relation to the guide rail, preventing the movement from jamming.
  • this system can be used in any type of structure comprising a retractable roof, where the retractable roof can also be of different shapes depending on the facility in which it is to be installed.
  • the roof can be extended in length as desired, adding as many trusses as necessary and lengthening the surface of the tarpaulin to the desired size.
  • It can be made of any material known in the construction sector, such as steel, aluminium, wood or others; and the design of the truss can be of any shape as long as it complies with the manufacturing standards for roof construction. It can also be made up of pieces that can be assembled with through-bolts, always ensuring that the final truss is light, resistant and, above all, safe.
  • the roof can be supported in different ways.
  • the structure supporting the cover can be self-supporting, i.e. it is a self-supporting structure, without the need for it to be attached to the padel court or facility in question by means of the columns welded to the padel court, in which case if you were to remove the court, the cover might come down.
  • the retractable roof can be supported on a belt that joins all the columns and the columns can be fitted with braces to reinforce the structure so that it is supported without the need for it to be attached to the actual structure of the padel court or the facility that is to be covered.
  • the cover can be fixed to the structure of the facility itself, i.e. a padel court, as in the previous case.
  • a padel court i.e. a padel court
  • the roof rests on support pillars, either in the self-supporting structure or the conventional structure of the facility itself.
  • the truss runners are then inserted through the ends of the rails.
  • This operation can be quick and simple, and only requires two workers: one worker lifts each truss by its middle using a manual load elevator, while the other worker checks that the runner is in line with the guide rail and inserts it in the rail from a ladder.
  • one of the workers inserts a through-bolt in all the ends of the guide rails as a safety stop to prevent the trusses from sliding out lengthwise.
  • the guide rails are sections welded to another rectangular section that has a third element attached, i.e. a toothed rack to enable the traction of the trusses on the guide rail by means of the motor pinion and cogs, where these elements thus create a single assembly.
  • This unit is fitted by joining together as many sections as necessary to cover the desired area.
  • the support pillars are structural sections that can be attached to the metal structure of the place where the roof is to be installed, for example, a padel court, by means of flanges or bolted plates when there is an existing structure, which will save in building work, discreetly integrating the design of the roof.
  • the space will also be used and, in this way, no obstacle will be placed in the perimeter corridors of the court.
  • the height of the support pillars is variable depending on the facility or area that is to be covered. For sports facilities, the height will depend on the sport in question, always leaving a free space up to the height authorised by each federation or official body.
  • the outer wall of the runner comprises a central opening to improve the connection between the guide rail and the support pillar. This allows for better movement or displacement of the runners, and improves the connection between the guide rail and the support pillars. This is important when there is a large number of such support pillars and they are fixed on the outside of each rail.
  • This central opening improves the movement of the runner and also avoids jamming or problems with the connection at the fastening points between the guide rail and the support pillars.
  • the material for the tarpaulin can be canvas, cloth, plastic or any flexible or pliable material. Air exhaust valves can be fitted to the cover material to prevent the sail effect.
  • the tarpaulin is fitted when all the trusses have been installed and collected at the end.
  • the tarpaulin is fastened to each truss using conventional pressure elements, preferably threaded.
  • the tarpaulin fits across the entire cover but sections of tarpaulin can also be fitted to cover the sides.
  • a motor is started up by remote control.
  • the motor is bolted to the first truss, the cog of the motor moves along a rack attached longitudinally to the guide rail and it extends from the start to the end of said guide.
  • This first truss is also fitted with bearings that turn a shaft that runs from one end of the truss to the other.
  • the ends of the shaft are fitted with cogs that transmit the movement of the motor when it moves from one guide to the other.
  • It is also fitted with a rack to enable the runners to move simultaneously on the two rails and ensure that the trusses are parallel.
  • the motor stops when the limit switch comes into contact with a fixed stop. The motor can be stopped at any time by operating the remote control.
  • the motor is operated with the remote control and the drive truss runs in reverse along the same sweep. This slackens each section of tarpaulin, dragging each mobile truss on the way owing to the contact of the wheeled runners on each truss against each other. At end of the sweep, the motor stops when the limit switch comes into contact with a fixed stop.
  • the retraction and extension actions described above are to collect the cover on one side of the facility only. To retract the tarpaulin on both sides of the facility, simply remove the racks and couple two shafts at the ends.
  • One will be the drive shaft and will be connected to the motor, which will be fixed by a fastening plate, and the other shaft will be driven by a chain joining them together from end to end of the sweep of the cover.
  • the motor trusses When the cover is extended, the motor trusses will be in the middle of the sweep. Accordingly, the chain will be attached to one of the drive trusses in the section that goes in one direction, and the other drive truss will be attached to the section that moves in the opposite direction.
  • the motor rotates in one direction
  • the chain will separate the two trusses and when it rotates in the opposite direction, it will bring them together.
  • the two rotation directions will therefore extend or retract the cover.
  • the motor At the end of the sweep, the motor will stop when a rev-counter limit switch counts the revs set for the extension and retraction of the cover.
  • the displacement system of the retractable roof object of this invention can be implemented in a structure comprising a retractable roof, where all such movement is automatic. Furthermore, the displacement system differs from any other system known in the state of the art. It improves stability, avoids jamming, makes it possible to maintain the verticality of the truss posts, does not interfere with the motor mechanisms of the cover, enables smooth movement of the assembly, which improves the durability of the cover, and in short, it improves the displacement of the retractable roof.
  • FIG. 1 shows a perspective view of the displacement system of this invention, namely how a runner is coupled to and runs along a guide rail.
  • a runner comprising two wheels in the upper row and two wheels in the lower row, where the wheels are in contact with the upper and lower curved surfaces of the guide rail.
  • This figure also shows how the truss post is fixed to the inner wall of the runner.
  • FIG. 2 shows a front elevation view of a retractable roof over a padel court, the retractable roof comprising the runner-and-rail system that is the subject of this invention.
  • FIG. 3 shows an enlarged view of the previous figure with the system that is the subject of this invention.
  • FIG. 4 shows a side elevation view of the retractable roof according to FIG. 2 , where it can be seen that the roof comprises a number of trusses that move by means of the system of this invention, where each truss has runners that move along the guide rails.
  • FIG. 5 shows an enlarged view of the previous figure with a runner comprising a top and bottom row, each with three wheels
  • FIG. 6 shows an enlarged view of FIG. 4 with a runner comprising a top and bottom row, each with two wheels.
  • FIG. 7 shows an aerial view of the retractable roof according to FIG. 2 , illustrating how the retractable roof can protect the entire surface of a padel court.
  • FIG. 8 shows a perspective view of the retractable roof comprising the runner-and-rail system subject of this invention in deployed position.
  • FIG. 9 shows a perspective view of the retractable roof in the retracted position.
  • the displacement system is designed to improve the movement of the trusses ( 1 ) that support the tarpaulins ( 2 ) or roof, and which, when joined together, form a retractable roof.
  • the roof is composed of a variable number of aligned mobile trusses ( 1 ), which move on two parallel rails ( 3 ), and the trusses are joined together by a canvas ( 2 ), deployed by the inertia of the first truss and set in motion by a motor ( 14 ) operated by a remote control or a pushbutton.
  • This moves the chains attached to at least one of the trusses to allow them to move, so that the roof can be kept unfolded as all the trusses are pulled by the first drive truss and where the last truss, which always remains fixed in position, is generally immobilised.
  • each truss ( 1 ) is made up of lateral posts ( 11 ) and transverse sections ( 12 ) that hold up the tarpaulin ( 2 ).
  • each side post ( 11 ) of a truss has a runner ( 4 ) attached with a number of grooved wheels, where each runner ( 4 ) is fitted to a guide rail ( 3 ) such that the runner can move along the guide rail.
  • a runner ( 4 ) is made up of two side walls facing each other, where the truss is fixed on the inner wall ( 5 ) to the post ( 11 ), and between these walls there are at least two grooved wheels fixed at two heights.
  • the wheels are fixed between the side walls by means of a shaft in the form of a bolt bearing ( 6 ). Therefore, there is an upper row ( 7 ) of grooved wheels and a lower row ( 8 ) of grooved wheels.
  • the upper side of the guide rail ( 3 ) comprises an upper curved surface ( 9 ) and the lower side has a lower curved surface ( 10 ) with which the grooved wheels of the runner make contact and along which they run.
  • FIGS. 5 and 6 show that within the same system, there can be runners where the top and bottom row of the grooved wheels can each have two and three wheels. It is recommended that in the initial and final trusses, which are more exposed to stress forces, the runners have more than two wheels, as this improves the stability of the assembly and the displacement of the set of trusses joined together by the tarpaulin.
  • the truss can remain vertical; the movement is smooth; the durability of the tarpaulin is improved; the movement is safe with no runner coming out of the rail as the rail is enclosed between the two wheel heights and the side walls of the runner; and there is an improvement in the weight distribution of each truss and the tarpaulin in relation to the guide rail, preventing the movement from jamming.
  • the guide rails ( 3 ) are mounted on self-supporting pillars ( 13 ), which are distributed at the same height along the entire side of the padel court, such that the guide rails are not only aligned and parallel, but also level, and the runners move correctly so that the tarpaulin ( 2 ) can fold and unfold as necessary, therefore covering the padel court as shown in FIG. 8 or leaving it in the open air, as shown in FIG. 9 .
  • the outer wall of the runner comprises a central opening ( 15 ) to improve how the runners ( 4 ) slide along the guide rail ( 3 ), preventing jamming or problems with the connection between the guide rail ( 3 ) and the support pillars ( 13 ).
