Definitions

  • the present invention relates to the field of tables, and more particularly that of tables having a tray and one or more movable feet (s).
  • Such tables are already known, conventionally characterized in that the movable foot, if the table has only one, or each movable foot, if the table has several, is able to be moved to adopt at least one predetermined position in which the table is in a stable use configuration.
  • the table includes a foldable rectangular tray; and two movable feet which are both pivotable about an associated vertical axis, so that both feet can be arranged both in the lateral direction of the tray, when it is desired to fold the latter, than in the longitudinal direction of the plateau, when it is desired to deploy the latter.
  • the wheelbase i.e. the inter-foot distance
  • the width of the plate is limited by the width of the plate.
  • the small range of movement of the movable legs of a table according to this patent requires the designer to have to make an exclusive choice between ensuring a good stability of the table in its expanded tray configuration and prefer to opt for a tray having a large length.
  • the present invention proposes to realize such a new kinematics.
  • a table according to the present invention is defined by claim 1.
  • horizontal is meant a direction that is substantially parallel to the upper face of the plate (ie the face of the plate which is intended to serve as useful surface of the table, on which objects can be placed) and the ground plane when the table is placed on its feet on a supposed horizontal ground.
  • vertical will be used to describe a direction that is substantially perpendicular to the upper face of the plateau and to the ground plane, when the table is placed on its feet on a supposed horizontal ground.
  • the first foot is not connected directly to the plate but on the contrary via a connecting rod.
  • the first leg is pivotable relative to the connecting rod, which itself is pivotable relative to the plate.
  • the first foot can thus deviate and approach the first axis with a range of motion that depends only on the size of the center of the connecting rod (the distance between the first axis and the second axis).
  • first foot and / or the rod can further translate in the lateral direction of the table during their respective movement between the first and second position of the first foot (For example, to allow locking / unlocking the first foot in its first or second position), it is still preferable to prevent these translational movements to increase the robustness of the table.
  • first leg is pivotally rotatable about the second axis of the connecting rod to move from a first position in which its first end and its second end are respectively turned towards the plate and towards the ground, to a second position. position in which its first end and its second end are respectively turned towards the ground and towards the plateau.
  • first and second ends of the first leg are both free to move relative to the plate while allowing that in the first position, the plate rests on the first end of the first foot.
  • the table may advantageously comprise means for wedging the first end of the first foot relative to the plate in the first position, so as to prevent any inadvertent movement of the first foot when the latter has adopted his first position.
  • the stability of the table can be improved when the first foot occupies its first position.
  • the connecting rod is connected to the first foot in a place of the latter which is located between its first and second ends (in an intermediate position of the first foot which is located between the first end and the second end of the first leg) and at a distance of these.
  • first and second ends of the first foot can both describe a circular path in the reference frame of the connecting rod.
  • the fact that the first foot can be returned can be advantageously used so that the table is able to rest on the first foot not only when it adopts its first position but also when it adopts its second position.
  • the plate can advantageously be supported on the second end of the first foot when the latter is in its second position, so as to increase the rigidity and stability of the table in this configuration.
  • the table may optionally include means for wedging the second end of the first foot relative to the plate in the second position, so as to avoid inadvertent movement of the first foot and thus increase the stability of the table when the first foot is in its second position.
  • the first foot since the first foot is connected to the connecting rod by a pivot connection whose axis is the second axis, the first foot forms a first angle with the connecting rod when it adopts its first position, and forms a second angle distinct from the first with the connecting rod when he takes his second position.
  • any value for the first angle and any value for the second angle can be chosen, provided only that, from a first position in which its first end and its second end are respectively turned towards the plate and towards the ground, the first leg can be returned by pivoting around the second axis of the connecting rod to adopt a second position in which its first end and its second end are respectively rotated towards the ground and towards the plateau.
  • the second angle is close to zero (in particular less than 10 ° in absolute value), so that when the first foot is in its second position, the latter is substantially parallel to the connecting rod.
  • the first foot has a recess in which at least a portion of the rod is housed when the first foot adopts its second position.

  • the table may advantageously comprise a substructure to which is connected the first foot via its connecting rod and the second foot.
  • the tray can then be fixedly mounted on this substructure when it is desired to assemble the table to use it.
  • the tray can also be detached from this substructure when it is desired to disassemble the table to store it.
  • the tray is stored separately from the substructure which can occupy a minimized volume advantageously taking advantage of the kinematics of the present invention so that the first foot in its second position is close to the second foot.
  • the plate comprises a support portion which supports the first axis of the connecting rod, and at least a first folding portion pivotally mounted relative to the support portion, so as to be able to move between an unfolded configuration in which the first foot can be placed under the first folding part, and a folded configuration in which the first foot is placed under the support part.
  • first position of the first foot is obtained when the latter is placed under the first foldable part in its unfolded configuration, while the second position of the first foot is obtained when the latter is placed under the support part so as to be able to fold down the first folding part.
  • the first folding portion in its unfolded configuration may advantageously come to bear on the first end of the first foot, when The last one adopts its first position, so that the first foot participates in maintaining the first folding part in its unfolded configuration.
