Definitions

  • the present invention relates to the technical field of handling devices of a roll-over roof element over a surface in the general sense.

  • a gantry comprises a winding mandrel for the cover element, extending transversely above the surface to be covered.
  • Such a device also comprises motor means simultaneously providing a rotational movement of the winding mandrel and a translational movement of the gantry along the guide rails.
  • a disadvantage of this solution lies in the need to equip the edges of the space to be covered by guide rails for the gantry, which hampers access to the space to be covered.
  • a handling device requires the use of synchronization means between the mandrel rotating drive means and the gantry displacement means so that such a device has a high cost and complexity of implementation. implemented.
  • a device for covering and uncovering a surface by means of a roll-up cover element is in the form of a gantry comprising a central shaft equipped at each end with a wheel forming part of a remote carriage from each other a measurement greater than the width of the surface to be covered.
  • a device also comprises a winding mandrel and unwinding for the cover element supported by the two carriages.
  • Such a device also comprises means for driving on the one hand the carriages and on the other hand the winding mandrel of the covering element.
  • Such a device does not allow to wind the cover element independently of the movement of the gantry.
  • the present invention therefore aims to achieve such an objective by providing a device for covering and uncovering a surface using a roll-up cover element, the device being designed as a gantry provided with displacement means ensuring its translation in a given direction above the surface substantially perpendicular to the width of said surface, the gantry comprising on the one hand a central shaft equipped at each end with at least one wheel remote from each other; a measurement greater than the width of the surface and secondly a winding mandrel and unwinding for the cover member, rotated by drive means.
  • the central shaft is provided with rotational guiding means for the mandrel which extends around said shaft being mounted free to rotate relative to the central shaft and in that the displacement means comprise a manual operating member adapted to allow to exert a force on the gantry in its direction of travel.

  • the rotational drive means comprise a reducer coupled in rotation with the mandrel and with a drive motor member supported by the support body.
  • the rotary drive means comprise a geared motor coupled in rotation with the mandrel.
  • the rotational drive means comprise control means in the opposite direction to ensure the winding or unwinding of the cover element relative to the mandrel.
  • Another object of the invention is to remedy this drawback by proposing a new method for covering and uncovering a surface using a roll-up cover element adapted to support the weight of a person.
  • the method consists in simultaneously ensuring the winding control of the mandrel and the movement of the gantry above the surface in order to wind the flap on the mandrel.
  • the device 1 according to the invention is intended to cover and discover with the aid of a roll-up cover element 2, a surface 3 defining a two or three-dimensional space.
  • the cover element 2 which is schematically represented in the Fig. 1 Presents a windable character and is able to perform a protective function and / or concealment.
  • the roll-up cover element 2 is in the form of a tarpaulin, a curtain or a shutter.
  • the device 1 according to the invention thus makes it possible to cover and discover the surface 3, for example of a pool, a container, a vehicle or a meeting room.
  • the device 1 is in the form of a gantry comprising a central shaft 4 equipped at each end with at least one wheel 5 distant from each other by a measurement greater than the width 1 of the surface 3 to cover.
  • the gantry is thus intended to move above the surface 3 in a translation direction represented by the letter F, substantially perpendicular to the width 1 of said surface.
  • the wheels 5 and roll on the longitudinal edges 3 1 of the surface 3 to be covered.
  • each wheel 5 has a diameter greater than 50 cm and preferably of the order of 60 cm so as to facilitate the mobility of the gantry.
  • each wheel 5 is mounted on the shaft 4 by means of disengageable mounting means 6.
  • disengageable mounting means 6 may be formed by a connecting pin passing through the axis 4 and the hub 5 1 of a wheel 5.
  • the wheels 5 can be motorized to move the gantry in translation.
  • the device 1 also comprises a mandrel 7 for winding and unfolding for the covering element 2.
  • the mandrel 7 extends around the shaft 4 between the two wheels 5.
  • the mandrel 7 is guided in rotation by the guide means 8 mounted on the central shaft 4.
  • the mandrel 7 is rotatably mounted with respect to the central shaft 4. In other words, there is no angular connection between the mandrel 7 and the central shaft 4.
  • the mandrel 7 is supported at each end by a guide bearing 8 mounted on the central shaft 4.
  • the mandrel 7 surrounds thus concentrically the central shaft 4.
  • the device 1 also comprises means for driving in rotation 11 of the mandrel 7 so as to ensure the winding or unwinding of the cover member 2 around said mandrel.
  • the rotary drive means 11 are embedded on the gantry. These rotational drive means 11 are equipped with not shown control means for controlling the rotation of the mandrel 7 in two opposite directions of rotation to select the winding or unwinding of the cover member 2 around the mandrel 7.
  • the rotary drive means 11 are made in any suitable manner and may be fluidic, electric or manual in nature.
  • the rotary drive means 11 comprise a gear 12 coupled in rotation with the mandrel 7 and with a not shown drive motor member supported by a body 13.
  • a motor member of FIG. drive is an onboard electric motor mounted inside the support body 13 located at one end of the gantry.
  • the gear 12 may be connected to a receiving head for a removable motor, or for a manual drive member.
  • the rotary drive means 11 can be carried out by a tubular electric motor interposed between the shaft 4 and the mandrel 7.
  • the support body 13 is adapted to take up the tilting torque of the rotary drive means 11.
  • the support body 13 is supported by the central shaft in the vicinity a wheel 5 and is in contact with the ground S.
  • the gantry is provided with displacement means 14 ensuring its translation in the direction F.
  • the displacement means 14 are of manual type and comprise a manual operating member 15 adapted to exert a manual effort on the gantry in its direction of travel F, as will be explained in the following description.
  • the displacement means 14 support, at least in part, the drive means 11 of the mandrel 7.
  • the displacement means 14 are constituted by the support body 13 which is in the form of an arm extending substantially perpendicular to the central shaft 4 and ending with the actuating member 15 such as a handle.
  • the operator upon movement of the gantry, moves along a longitudinal edge 3 1 of the surface to cover 3.
  • the support body 13 is equipped with a rolling member 18 facilitating the movement of the gantry according to its direction of movement F.
  • the rolling member 18 such that a wheel is able to roll thus according to a parallel to the rolling direction of the wheels 5.
  • the wheel 18 is mounted at the end of a fork 19 extending from the arm 13 so that when the moving means 14 rest on the ground S, by the wheel 18, the handle 15 is positioned correctly to allow a user to apply a pushing force or traction on the gantry to ensure its longitudinal movement.
  • the device 1 For coating a surface 3, the device 1 according to the invention is arranged along a transverse edge 3 2 of the surface 3 to cover while being positioned to span the surface along its width.
  • the roll-up cover element 2 is attached by one of its ends to a transverse edge 3 2 delimiting the surface 3 to cover while its other end is attached to the mandrel 7 around which the bulk of the cover element 2 is wound.
  • the rotational drive means 11 are then controlled in a direction leading to the unwinding from the mandrel 7, the cover member 2. Simultaneously, an operator provides, for example, traction on the gantry, using the manual operating member 15.
  • This pulling force leads to displacement of the gantry above the surface 3 according to the traveling direction F, and the voltage of the cover member 2 which is held in from the mandrel 7.
  • the device 1 can be immobilized at any overlapping location of the surface 3.
  • the cover element 2 can be detached from the mandrel 7 of so as to be fixed on the other transverse edge 3 2 of the surface to be covered 3.
  • the rotary drive means 11 are controlled so as to ensure the winding of the cover element 2 around the mandrel 7.
  • the winding of the covering element 2 leads to the displacement of the gantry in its direction F so that the operator exerts a minimum force for example of thrust on the operating member 15.
  • the device 1 according to the invention makes it possible to cover and discover a surface easily, without, however, providing complex guide arrangements on the edges of the surface to be covered. Furthermore, the handling device 1 according to the invention offers the advantage of being able to cover and discover a surface without requiring the deployment of significant efforts.
  • Another advantage of the handling device 1 according to the invention is to allow the deployment of a cover element 2 of similar shape to that of the surface 3 either directly on the surface 3 such as on the surface of the water.
  • a basin for example, at least on the longitudinal edges 3 1 in order to avoid contact between the water surface and the cover member 2.
  • the process according to the invention is to realize as a roll-up cover element 2, a self-supporting flap of greater width than the surface 3 so that it can rest on the longitudinal edges 3 1 of the surface and possibly the transverse edge 3 2 opposite to that from which the flap is secured.
  • the self-supporting part is supported by transverse edge 3 2 of which it is fixed.
  • the self-supporting flap can therefore be made in various shapes similar to those of the surface 3, having larger dimensions to rest on the edges of the surface 3.
  • the self-supporting flap consists of a series of transverse rigid slats hinged together to allow the winding of the flap.
  • Such rigid hinged flap is adapted to bear at least the weight of a person when it is supported simply by the ends of the rigid slats.
  • the handling device which is made in the form of a gantry movable in a direction of translation above the surface 3, comprises a motorized mandrel of width adapted to receive such a self-supporting flap.
  • the gantry is dimensioned so as to be supported by the longitudinal edges 3 1 leaving, with each longitudinal flange 3 3 of the surface 3, a bearing space 25 for the self-supporting flap.
  • the covering of a surface 3 by means of a self-supporting flap is carried out as described previously. Indeed, during the unwinding command of the mandrel 7 and the concomitant movement of the gantry, the self-supporting flap is deposited above the surface 3 while resting on the bearing space 25 adjacent the longitudinal edges 3 1 . Of course, the self-supporting component rests on an edge surface large enough to form a rigid surface even when a person walks on such a flap.
