Definitions

• the present invention is in the field of screens. It relates more precisely to mobile screens with variable lateral deployment.
• screen any interposed object, arranged in a vertical plane, which is used in particular, but not exclusively, to conceal or protect a space.
• screens have been composed of elements of defined dimensions and connected together by hinges or other pivoting connection systems. They include several modules that must be placed side by side in more or less closed angles to each other to keep them standing on a horizontal surface.
• Other screens consist of a panel held in a vertical position by feet fixed perpendicular to said panel, thereby hampering the movement of people and things. These types of screens are relatively unstable. The surface used to protect or hide a person or a set of objects is rigidly defined by the dimensions, the arrangement and the number of modules available.
• Other types of screens are fixed to the ceiling or wall and due to their permanent installation are not easily movable.
• Another type of existing screen consists of a fixed container from which a panel or a canvas is extracted to hang it at another fixed point. A variant is that the container is movable, but heavy and unwieldy due to its strong ballast.
• the present invention aims in particular to remedy the problems of visual and temporary masking or privacy, in particular in medical offices, homes for elderly residents or people with disabilities, hospital rooms, temporary exhibitions, offices and meeting rooms. open conference, some interior public spaces, private apartments.
• the present invention provides a solution consisting of a screen of total mobility, mobile by nature, easily movable with one hand, even from one room to another, and extendable in width without fixed bearings and taking up very little space when it is waiting to be used.
• the present invention relates to a screen as defined in the main claim.
• the screen consists essentially of three main parts which consist partly of a movable support element, of an extractable element without bearing, and secondly of a holding receiver element.
• the carrier element is composed of a hollow tube arranged vertically, of polygonal section. It is held in its lower part by a fixed and rigid link on a hollow base and containing a mechanism controlling a platform on casters.
• the base is provided on its lower periphery with a rubber-type seal for connection to the ground.
• a return spring winding axis is maintained vertically around which is fixed and wound a fabric or a film of a structure and an appropriate holding. This fabric or film is held outside the carrier element at its free end by a small diameter cylinder protruding at the top and bottom of the fabric or film, allowing the attachment and retention on the wall.
• the receiving element is mainly composed of two hooks fixed on a vertical surface such as a wall, a partition or any other architectural element.
• the hooks are in two parts, one fixed to the wall and the other removable.
• the shape of the removable hooks makes it possible to retain the cylinder at will while allowing the vertical displacement of said cylinder.

• the mobile screen with variable lateral deployment is composed of a carrier element 1 provided with retractable casters 11, a flexible element 2 and extractable without bearing, and a holding receiver element 3.
• the carrier element is in the form of a vertical tube 4 fixed on a hollow foot 5 containing a mechanism 14 controlling a mobile platform 10 with retractable casters 11 by means of a handling handle 6. Its foot 5 comprises a seal 13 for connection to the ground.
• a return spring axis 12 is maintained around which a fabric 2 or a film 2 is wound.
• the extractable element such as a fabric 2 or a film 2 is maintained outside the support element 4 at its free end by a rigid element 7 protruding above and below allowing the attachment to the wall with the hooks 8.9.
• the receiving element 3 is composed of two hooks 8, 9 part of which is fixed to a vertical surface such as a wall, and the other part is removable.
• the control mechanism 14 transforms the rotary movement of the handling handle 6 incorporated into the hollow tube 4 into a linear and vertical movement of the platform 10 on wheels 11, keeping the latter in strict horizontality during its movement.
• One of the preferred operations of the invention is as follows: in the rest position, the carrier element rests on the ground, the screen retracted, the rollers raised. To move the load-bearing element, the platform on casters is lowered by slightly actuating the handling handle, thereby lifting the load-bearing element from the ground, allowing effortless movement of this load-bearing element and its extractable element. 'chosen place.
• the carrier element is approached near the vertical surface where the hooks are fixed beforehand. The ends of the cylinder integral with the extractable element are introduced into the two hooks.
• the handle is actuated again, lifting the load-bearing element, lowering the rollers, thus making it possible to roll towards the wall hooks, the fabric wrapping around its special spring-loaded axle, releasing the handle, the rollers retract and the support element rests stable on the floor, thus taking up very little space when stored. All these operations are easily done with one hand, the whole being very light.
