    DESCRIPTION
    Assistive device for lifting a roof element Scope of the invention
    The present invention relates to the scope of roof structures intended to partially or completely cover a surface on the floor, such as that defined by the glass of a pool.
    The invention relates above all to a device that facilitates the opening of said structures.
    State of the art
    In the prior art there are several types of pool ceilings, especially the roofs commonly called "low cover", so named because they have a height less than the size of a human being. These ceilings are composed of several juxtaposed roof elements, in a longitudinal direction to the pool vessel, each roof element covering a part of the length of the vessel along its entire width.The roof elements can be independently manipulated from each other to release access to the covered surface.
    Each roof element consists of two longitudinal support edges that rest respectively on the flange or the curb that surrounds the two opposite longitudinal edges of the pool vessel.
    To partially discover the pool vessel, the roof elements are mounted so that they can be ajar individually to modulate the opening of the vessel to the outside. For this purpose, one of said longitudinal support edges of a roof element is mounted in an articulated manner, in rotation, so that it can ajar the roof element by raising the other longitudinal support edge on the opposite edge of the vessel.
    To ensure that the ajar position of the roof element is maintained, various solutions are provided.
    The simplest solution is to use independent and removable elements that act as supports on which the other longitudinal support edge rests when it is ajar. This solution has numerous drawbacks, mainly in terms of the manipulation of the roof elements. On the one hand, this solution forces the user who wishes to open the roof element, taking into account the weight

    significant of the roof element, to exert a relatively important effort to make it swing in relation to its articulation. On the other hand, the placement of the supports is complicated to carry out. Indeed, it is difficult to keep the roof element in ajar position and install the support at the same time. In addition, this solution results in a relatively long installation for all the roof elements that constitute the roof.
    In recent years, numerous improvements have been made to lighten the lifting operation of the roof elements by proposing, above all, various lifting assistance systems to limit the efforts required by the user. Among others, patents FR 2,785,937 and FR 2,900,952 may be mentioned.
    However, despite these different innovations that significantly improve the passage of the roof elements from a closed position to a partially open position avoiding the maximum efforts that the user must make during this operation, the opening of said roof elements continues being a complicated handling operation.
    Description of the invention
    The present invention aims to remedy these disadvantages.
    The present invention aims above all to provide an effective solution that allows to reduce, in a significant way, or cancel the effort exerted to open the roof element considered, further ensuring its maintenance in a partially open position.
    Thus, the invention relates to an assistive device for lifting a roof element, especially for pool cover, said roof element comprising a first and second opposite longitudinal support edges intended to rest on a surface of support, the first longitudinal support edge being able to pivot, at the level of an articulation axis, to allow the roof element to switch between a closed position and a half-open position.
    The closed position corresponds to a position in which the two opposite longitudinal support edges rest on the support surface, keeping the second longitudinal support edge against the support surface, for example by reversible fixing means.
    The ajar position corresponds to a position in which only the first longitudinal support edge rests on the support surface, the second support edge being
    5
    10

    longitudinal free and distant from the support surface, thus allowing access to the surface covered by the roof.
    By "longitudinal", and "transverse" extension, corresponding directions are understood, respectively, to those of the length and width of the coated surface, especially a pool vessel, whether these adjectives are applied to said ceiling elements as to other constitutive pieces.
    Similarly, "outside" means the environment above the roof element, not protected by the roof element.
    And "inside" means the environment covered by the roof element. In the preferred example of a roof element for pool cover, the interior is located on the side of the pool vessel.
    The lifting aid device is characterized in that it consists of return means intended to be placed outside the roof element, on the side of the first longitudinal support edge, and arranged to facilitate the rotational movement of the roof element towards the position ajar when the second longitudinal support edge separates from the support surface. Said return means comprise a first end intended to be jointly and severally connected to the pivoting ceiling element and a second end intended to be attached to the support surface.
    This feature is especially advantageous because it alleviates the drawbacks of the lifting assist devices of the prior art. In fact, by placing the lifting device on the side of the first longitudinal support edge, unlike the prior art lifting assistance devices that are placed on the side of the second longitudinal support edge, this ensures the rotational movement of the roof element over a given angular range, sufficient to ajar the roof element and authorize access to the coated surface. The opening of the roof element, as regards the separation of the second longitudinal support edge from the support surface, is automatic, the roof element being rotatably driven by the return means.
    The use of return means allows to ease the weight of the roof element for the user and facilitate the operation of opening said roof element by a single user. In this way, the user can manipulate the roof element to their liking without effort or with a slight lifting or holding effort.
    In addition, the placement of the return means very close to the first support edge

    longitudinal is especially interesting, because it allows not to hinder the support surface, on the side of the second longitudinal support edge, and facilitates access to the coated surface.
    In addition, the return means are advantageously placed outside the ceiling element to avoid any contact with the chlorinated medium, an aggressive medium that could accelerate its degradation.
    Following preferred modes of application, the invention also responds to the following characteristics, applied separately or in each of its technically operational combinations.
    According to preferred embodiments, the return means comprise a linear actuator and a lever arm intended to be connected with a transverse arc and capable of transforming the linear movement generated by the linear actuator into an angular movement of the ceiling element when the second edge Longitudinal support is separated from the support surface, that is, when the second longitudinal support edge is released from the reversible fixing means. The return means are sized in such a way that the force exerted by said return means directly opposes the weight of the roof element to be overcome. In this way, the return means allow to compensate totally, almost or more, the weight of the roof element. Therefore, the user opens the ceiling element effortlessly or with a slight effort, which allows a single user to easily manipulate the opening of the ceiling element.
    According to preferred embodiments, the lever arm is arranged so that it can be inserted into one of the transverse arches of the ceiling element. The transverse arches associated with the longitudinal support edges partly form a framework of the roof element. The transverse arches extend over the entire width of the surface covered by the roof element.
    According to preferred embodiments, the lever arm is arranged so that it can be supported, by a second end, on a lower face of a transverse arc of the ceiling element, the lower face being located on the side of the coated surface.
    According to preferred embodiments, the linear actuator is a spring arranged so that it works in compression or traction.
    According to preferred embodiments, the linear actuator is a gas spring arranged so that it works in compression or in tension.

    According to preferred embodiments, the linear actuator is associated with an adjustment screw designed to allow the linear actuator to adapt to the bearing surface taking into account the linearity defects at the location of said linear actuator.
    According to preferred embodiments, the return means comprise an angular motion actuator capable of dragging the rotating roof member about the axis of rotation when the second longitudinal support edge separates from the support surface, that is, when the Second longitudinal support edge is released from the reversible fixing means. The return means are sized in such a way that the torque exerted by said return means directly opposes the torque formed by the weight of the roof element to be manipulated. In this way, the return means allow to compensate totally, almost or more, the weight of the roof element. Therefore, the user opens the ceiling element effortlessly or with a minor or reduced effort, which allows a single user to easily manipulate the opening of the ceiling element.
    According to preferred embodiments, the angular motion actuator is a helical torsion spring, a spiral spring or a mechanical reducer driven in rotation.
    The invention also relates to a cover, especially of a pool vessel, comprising at least one roof element, which comprises at least one support device for raising the at least one roof element according to one of its modes and shapes. of realization.

    Detailed description of an embodiment of the invention
    As illustrated in Figure 1, a cover 100 according to an embodiment of the invention is a cover of the low, collapsible type cover, which covers a pool-type glass 500, lying in a longitudinal direction, illustrated by the X axis. More especially, in Figure 1, the cover 100 is shown in a semi-open configuration above a part of the vessel 500.
    Although the cover 100 is described to cover a pool glass 500, it can also ensure the coating of any other surface on the floor, such as a cultivation plot, a sports / game area or a decorative pond, without deviating from the frame of the invention.
    The cover 100 consists of several roof elements 10 of the type that are composed, each of them, on the one hand, of a cover formed by panels 11 and, on the other hand, of a rigid, light and sturdy shaped frame of transverse arcs 111, arranged in transverse directions, illustrated by the Y axis in Figure 1, and secured by longitudinal crossbars 121, 122, 123, to support said coverage.
    As can be seen in Figure 1, by way of example, three roof elements 10 are represented in a closed position and allow partially covering the vessel 500 and four roof elements 10 are represented in a half-open position and thus allow to discover partially the 500 pool glass.
    The panels 11 are made in a known manner with a preferably translucent material such as polycarbonate, for example.
    The transverse arches can present any profile. For this purpose, the profile illustrated in the figures should not be considered as limiting the invention.
    The transverse arches are preferably made of a metal or resin / composite material.
    The two longitudinal crossbars 121, 123 that delimit and constitute the two fences

    10
    fifteen

    25
    30
    Longitudinal parallel sections of a roof element are called longitudinal support edges 121, 123.
    These two longitudinal support edges 121, 123 rest on longitudinal flanges 501 of the vessel 500 or are rearward in relation to the longitudinal flanges of the vessel, on a glass of the vessel or on a terrace surrounding the vessel. These longitudinal or curb flanges define a bearing surface S for each roof element 10.
    As illustrated in Figure 1, each roof element 10 is of the type in which at least one longitudinal support edge is articulated in relation to the support surface, articulation in relation to which pivots to move from the closed position to A slightly open position. This longitudinal support edge is called the first longitudinal support edge 121.
    The first longitudinal support edge 121 is fixed to the support surface by fixing means (not shown in the figures) that act as a hinge, and is articulated at the level of an articulation axis 124. The other longitudinal support edge, called Second longitudinal support edge 123, substantially parallel to the first edge, is free and rests on the support surface S. The second longitudinal support edge 123 is removably fixed to the support surface by reversible fixing means.
    In order to partially discover the vessel 500, the second longitudinal support edge 123 of at least one roof element 10 is released from its reversible fixing means on the support surface S, allowing said roof element to perform a tilting movement on its first Longitudinal support edge 121 according to an angular expansion, represented by arrow B in Figure 1.
    When a roof element is in a half-open position, supports 30 (Figure 7) are arranged at the level of the second longitudinal support edge 123 and ensure a connection with the support surface S to keep the roof element 11 in a half-open position and provide a complementary security to a user of the glass.
    In a particular embodiment, illustrated in Figure 7, pins 40 are arranged, preferably at the level of the second longitudinal support edge, such that they join two roof elements juxtaposed with each other when they are in a half-open position. In this way, the number of supports 30 is limited and allows not to clog the support surface on the side of the second longitudinal support edge 123, offering easier and safer access to the vessel.
    According to an advantageous feature of the invention, to facilitate the rotation movement

    25
    30
    of a roof element 10, the first longitudinal support edge 121 of said roof element is associated with a lifting aid 20.
    The lifting aid 20 comprises, advantageously, return means 21; 25 arranged to facilitate the rotational movement of the roof element 11 towards the ajar position.
    Said means of return 21; 25 comprise a first end intended to be fixedly attached to the pivoting ceiling element 10, at the level of the first longitudinal support edge 121, and a second end intended to be fixedly joined, that is, without degree of attachment and / or rotation, to the surface of support S.
    The return means 21; 25 are adapted to exert, according to their embodiments and their placement in relation to the roof element 10, a force or a pair on the roof element 10 that substantially compensates for the weight of said roof element. In this way, the ceiling element 10 can be raised to the level of its second longitudinal support edge 123 without difficulty by a user.
    The return means are preferably placed outside the ceiling element so as not to disturb the users using the vessel or cause possible injuries in case of contact of the users with these return means.
    In a first embodiment, as illustrated in Figures 2a to 3b, the return means 21 comprise a linear actuator 22 and a lever arm 23 capable of transforming the linear movement generated by the linear actuator 22 into a rotational movement of the roof element.
    The return means 21 are adapted to exert a force on the ceiling element that substantially compensates, or more, the weight of the ceiling element 10 to be manipulated.
    The linear actuator 22 is attached, on the one hand at a first end 221 to the bearing surface S in a fixed manner and, on the other hand at a second opposite end 222 to a first end 231 of the lever arm 23. The lever arm 23 is connected, by a second opposite end 232, to a transverse arc 111 or to the articulation axis 124, in case said articulation axis is connected to the transverse arc 111.
    In one embodiment, the lever arm 23 and the corresponding transverse arc 111 form a single piece.
    In other embodiments, as illustrated in Figures 4a and 4b, the lever arm 23 and the corresponding transverse arc 111 are different parts.

    In an exemplary embodiment, illustrated in Figure 4a, the transverse arc 111 is a hollow profile. The lever arm 23 has a dimension, in cross-section, adapted to allow the insertion of the second end 232 in the hollow of the profile.
    In another exemplary embodiment, illustrated in Figure 4b, the second end 232 of the lever arm 23 is supported at the level of a lower face 112 of the transverse arc 111.
    The underside means the face facing the glass, on the inside of the cover.
    In a first embodiment of a linear actuator, as illustrated in Figures 2a and 2b, the linear actuator 22 is a gas spring 22. The gas spring consists of a body 223 and a rod 224 that slides in said body. The lever arm 23 transforms the linear movement of the rod 224 of the gas spring into a rotational movement of the transverse arc 111, and consequently of the roof element.
    In a first embodiment of the gas spring, Figure 2a, said gas spring is a tension spring.
    When the second longitudinal support edge 123 is separated from the support surface S, the rod 224 of the tension spring linearly exits the body 223, as illustrated by arrow A in Figure 2a, causing a movement of the lever arm 23 which, in turn, draws the roof element 10 in rotation, according to arrow B, to its ajar position.
    In another embodiment of a gas spring, Figure 2b, said gas spring is a compression spring.
    When the second longitudinal support edge 123 separates from the support surface S, the rod 224 of the compression spring enters the body 223, as illustrated by arrow A in Figure 2b, causing a movement of the lever arm 23 which, in turn, draws the roof element 10 in rotation, according to arrow B, to its ajar position.
    In an alternative to the first embodiment of the linear actuator 22, illustrated in Figures 3a and 3b, the linear actuator 22 is a spring.
    In a first embodiment of the spring, Figure 3a, said spring is a tension spring.
    When the second longitudinal support edge 123 is separated from the support surface S, the spring is naturally compressed, as illustrated by arrow A in Figure 3a, causing a movement of the lever arm 23 which, in turn, drags the element of
    5
    10
    fifteen
    twenty
    25
    30
    roof 10 in rotation, according to arrow B, to its ajar position.
    In another embodiment of the spring, Figure 3b, said spring is a compression spring.
    When the second longitudinal support edge separates from the support surface S, the spring naturally extends, as illustrated by arrow A in Figure 3b, causing a movement of the lever arm 23 which, in turn, drags the roof element 10 in rotation, according to arrow B, to its ajar position.
    Whatever the embodiment of the linear actuator, when the user wishes to close the roof element again, pull the second longitudinal support edge to lower it. The force, and respectively the torque, exerted by the user on the roof element, associated with the weight of said element, is greater than or equal to the force, respectively the torque, exerted by the lifting aid for opening and maintaining the roof element, and allows said roof element to be closed.
    Resorting to linear actuators is especially advantageous, since it has a minor obstruction and, consequently, does not cause any projection regardless of the position, closed or ajar, of the ceiling element. On the other hand, the cost of carrying out the lifting aid device is reasonable.
    In a preferred embodiment, the linear actuator is associated with an adjustment screw 60 to adapt it to the bearing surface and take into account linearity defects at the location of said linear actuator.
    In a preferred embodiment, the linear actuator is housed in a box 50 integrated on the longitudinal flanges 501 of the vessel 500 or, preferably, on the drill to make the lifting aid device more aesthetic but above all to ensure the implantation of the linear actuator.
    In a variant embodiment, the gas springs or springs are replaced by controllable linear actuators, for example both hydraulic, pneumatic and even electric springs.
    The hydraulic or pneumatic spring used by the invention works by feeding a fluid or a gas into its body to drive the rod.
    The practical application of the invention by electric, pneumatic or hydraulic automation is within the scope of the person skilled in the art using known tools.
    In one embodiment, the linear actuators can be remotely controlled, by
    5
    10
    fifteen
    twenty
    25
    30
    example using a wireless remote control.
    The box 50, advantageously, can be used to house a device for automating the movements of the controllable linear actuator.
    In a second embodiment of the return means, as illustrated in Figures 5 and 6, said return means comprise an actuator 25 of angular movement of the ceiling element.
    The angular movement actuator 25 is adapted to exert a torque on the ceiling element 10 that substantially compensates for the torque formed by the weight of the ceiling element 10 to be manipulated.
    In a preferred embodiment, illustrated in Figure 5, the angular movement actuator 25 is a torsion coil spring. The torsion spring consists of turns 251, of which at least a part of the turns is driven by the articulation axis 124. The torsion spring is provided with a first 252 and second 253 branch which extends on both sides of the turns 251, the first branch 252 being fixedly attached to a support that receives the articulation axis 124. The second branch 253, which defines the pivoting arm, is connected with a transverse arc 111 of the ceiling element 10 or of the articulation axis 124 .
    In another embodiment, the angular motion actuator is a spiral spring, the placement and operation of which is almost identical to the torsion spring.
    In another embodiment, the angular motion actuator is a gearmotor or a motor 255 with belt multiplier 256 or gears, as illustrated in Figure 6.
    Particular embodiments of the present invention have been described. Various variants and modifications will be apparent to the person skilled in the art. Above all, the invention adapts to any form of roof element panel 11.
    The above description clearly illustrates that, by its different characteristics and advantages, the present invention achieves the set objectives. In particular, it provides an assistive device for lifting a ceiling element that allows said panel element to be opened in a simplified and automatic manner as soon as the second longitudinal support edge is released from its locking means, while retaining the modular nature of the roof elements, thus facilitating their manufacture, transport and installation. Another advantage of the device lies in the gain of time obtained for the opening of these ceiling elements, without particular effort on the part of the user, that of
    This mode can be only for maneuvering the ceiling elements, unlike the prior art solutions that need two users.
