Definitions

  • the invention relates to a seat, such as a folding stool.
  • the US patent US 2002/0043866 proposes a device consisting of a flat sheet on which are arranged a plurality of fold lines. These fold lines define the outline of a seating surface, a plurality of foot portions and a plurality of sail portions all contiguous with each other.
  • the sheet can be folded along the fold lines to form a stool that can be placed on a support surface, the seating surface being away from the support surface, the feet extending from the surface of the sitting on the support surface, and the adjacent web portions being secured to one another.
  • the sheet is made of a thin but strong flexible material such as cardboard.
  • This device is lightweight and, in its unfolded state, has a very small footprint, which makes it easy to store and transport.
  • this foldable seat has a drawback, in that, to be able to form the stool, it is necessary to fix the parts of the sails to each other by means of a nut and a bolt, snap fasteners etc ... , which makes editing difficult. Indeed, the user will first of all have to fold the sheet according to the fold lines, then implement the fixing means which is relatively difficult and results in a waste of time, which can be detrimental, particularly when the you have to assemble a lot of stools, for example during a specific event. In addition, in its unfolded form, this device has no application.
  • the object of the present invention is therefore to overcome these disadvantages by providing a seat, such as a stool, foldable, lightweight, practical and easy to use, which, in its unfolded state also has a function, especially by acting of carpet, and folds into a stool by a single operation requiring no complex manipulation of the stool by the user.
  • this seat is economically advantageous.
  • the subject of the invention is a seat, such as a stool, foldable consisting of a sheet of flat material having a plurality of fold lines defining the contours of a central seating surface, feet and parts in fins between the feet, characterized in that said sheet is made of a flexible and flexible material and further comprises at the area corresponding to said feet and said seat surface at least one layer of rigid material the flat sheet being provided with means for controlling the folding of the sheet, so that when said folding control means is actuated, the sheet folds along said fold lines to form the seating surface and the feet a seat, the folding control means being arranged to fold the areas corresponding to the feet substantially perpendicular to the seating surface, and when the control means cease their effect, the seat is re unfolds in sheet.
  • a seat such as a stool, foldable consisting of a sheet of flat material having a plurality of fold lines defining the contours of a central seating surface, feet and parts in fins between the feet, characterized in that said sheet is made of a flexible and flexible material and
  • the folding seat according to the invention in its unfolded state, is in the form of a sheet of plane material, similar to a carpet, on which the user can extend or sit , avoiding him having to be in contact with the ground.
  • the user can at any time convert the carpet into a stool by a very simple operation of operating the control means which causes folding to achieve the folding seat according to the invention.
  • the seat according to the invention consists of a flat sheet provided with a plurality of fold lines formed on said sheet.
  • the fold lines define the contours of a central seating surface, a plurality of feet, and flexible vanes formed between the legs.
  • These fold lines are the main fold lines that can be formed, for example by ribbing, sewing or any other suitable method.
  • the flat sheet is made of a flexible and flexible material such as a high-resilience foam, which can be enclosed in a flexible fabric envelope.
  • the areas corresponding to the feet and the seat surface further include a rigid material such as plywood, flat board or any other suitable material conferring the desired rigidity. It is possible to fix, for example by gluing, this rigid material on the underside of the sheet, or alternatively insert it between two layers of flexible material constituting the sheet, or to put it in place in the flexible envelope enclosing a layer of foam.
  • the area corresponding to the seating surface and feet forms a cross consisting substantially of two rectangles whose intersection forms the central portion defining the seating surface of the folded seat, and whose branches define the foot zones.
  • the free surfaces or fin parts located between the branches of the cross are four in number and preferably have their substantially circular free edge.
  • the main fold lines are defined along the rectangles which constitute the cross comprising the rigid material and are materialized by a seam.
  • the folding control means are constituted by a plurality of flexible control members such as ropes, ropes or the like, fixed at one end to the underside of the sheet, to the foot zones and, at the opposite end, to a gripping member such as a handle, located on the top face of the flat sheet, through a central orifice of the sheet.
  • flexible control members such as ropes, ropes or the like
  • control members which, fixed to the zones forming the feet, cause the latter to bend along the fold lines situated along the contours of the seating surface for folding said legs perpendicular to the seating surface, each fin portion projecting outwardly between two adjacent legs to form a seat.
  • the points where these control members are connected to the foot zones are located substantially at 2/3 of the height of the foot, so as to ensure greater stability to the stool.
  • the seating surface is parallelepipedal, preferably square, and the flexible control members are four in number, and each fixed at one of their ends to an apex of a folding square having the same center as the seating surface and whose middle sides are the tops of the seating surface.
  • the control members are further connected to the handle through an orifice in the center of the seating surface.
  • the flexible members are all of the same length.
  • the seat surface is of rectangular section for example, the length of the flexible members is determined to allow the corresponding folding.
  • the folding control means further comprise a locking means for locking the control members in the folded position of the seat.
  • the locking means is constituted by a notch formed at the periphery of the seating surface and wherein the flexible control members are engageable so that the handle abuts against the notch.
  • the control means is locked in the folded position of the seat.
  • This stool is then rigid and stable so that an adult can sit. It will be sufficient for the user to release the control members and the handle out of the locking means so that the stool redeploys into a carpet.
  • folding control means comprising articulated rigid rods fixed on the underside of the sheet, in particular along the main fold lines, flexible control members being fixed to said rods to cause them to bend. and unfolding them.
  • additional fold lines are provided along the sides of the fold square, as well as the along four segments parallel to the members of the central cross and extending between the vertices of the folding square and the ends of the members of said cross.
  • Figure 1 illustrates the device according to a preferred embodiment of the invention in its unfolded state, forming a carpet.
  • the seat is in the form of a flat sheet 1 comprising at least one layer of flexible and flexible material 10 such as a high-resilience foam.
  • This foam is here enclosed in an envelope 11, for example fabric.
  • this sheet 1 is defined a zone having the shape of a cross based on two rectangles 2, 2 'intersecting at right angles, defining the seating surface 3 in the form of a square C and four zones forming the feet 4 of the stool.
  • This cross-shaped area is defined by layers 12 of plywood inserted into the envelope 11 on the underside of the layer 10 of high resilience foam.
  • the parts in fins 5 defined between the branches 4 of the cross have their substantially circular free edge.
  • the carpet here has a substantially square shape with rounded corners.
  • the sheet 1 has main fold lines 6 materialized by seams along the rectangles constituting the cross, that is to say on the contours of the seating surface 3 and the branches 4 of the cross.
  • the folding control means consist of four flexible control members 7 such as cords whose one end is fixed on a foot zone 4, substantially at 2/3 of the height of the foot, in the vicinity of a vertex d. a folding square C 'having the same center as the cross and whose sides of the sides are the vertices of the seat square C.
  • the other end of the control members 7 is fixed to a handle 9, the control members 7 passing through a hole in the center of the seating surface 3.
  • each flexible member 7 is defined so that each foot zone 4 is folded perpendicular to the seat surface 3 by a single stroke of the handle 9.
  • the seat surface 3 can be parallelepiped section square or rectangular or other.
  • the seating surface is of circular section, the fold lines being defined accordingly.
  • Figure 2 illustrates the same device in folding phase folded into a stool.
  • the legs of the stool are being folded perpendicularly to the seating surface 3, and the wing portions 5 protrude.
  • the control members 7, connected to the handle have also been driven outwards through the orifice provided in the center of the seat surface 3.
  • the four control members 7 are thus in contact with each other between the handle 9 and the central orifice.
  • the control members 7 are no longer in contact with the sheet 1 only between the central orifice and the points of attachment with the feet of the stool. Stretched each between these two points, these control members 7 ensure the folding of the stool.
  • a means for locking the folded position of the seat is provided.
  • This locking means is preferably constituted by a notch formed at the periphery of the seat surface 3 and into which the flexible control members are inserted, the handle 9 abutting the outside of the notch.
