Definitions

  • the present invention relates to a table.
  • Such conference tables often have large-sized table tops to make room for depositing a variety of files, drawings, and the like, and to ensure that a large number of people can sit at that table. Accordingly, such a conference table also requires a sufficiently stable base.
  • the present invention seeks to provide an improved table that can be stowed to save space, effortlessly and without danger to an operator person.
  • a table which has a first plate part and a second plate part, which are pivotable relative to each other from a utilization position into a storage position.
  • the table has a first support and a second support, a first rod and a second rod and a transmission with a transmission carrier.
  • the first and second supports serve to support the table against a floor.
  • first plate member is pivotally coupled to the first support, while the second plate member is pivotally coupled to the second support. Further, the first plate member is pivotally coupled to the gear carrier about a first axis.
  • the second plate member is pivotally coupled to the gear carrier about a second axis.
  • the first rod is pivotally coupled to the first support about a third axis, and the second rod is pivotally coupled to the second support about a fourth axis.
  • the first rod is with the gear carrier about a fifth axis pivotally coupled, and the second rod is pivotally coupled to the gear carrier about a sixth axis.
  • the idea of the present invention is to provide a table whose table top has at least a first and a second plate part, which can be brought by pivoting into a position in which the plate parts require considerably less space than in their utilization position.
  • a foldability of the table according to the invention is achieved.
  • the first rod and the second rod are pivoted about the fifth axis and the sixth axis with respect to the transmission carrier.
  • the spatial orientation of the first plate member to the first support and to the transmission carrier while at the same time changes the spatial orientation of the second plate member to the second support and to the transmission carrier.
  • the first rod and the second rod are arranged such that they intersect when pivoting the plate parts from the utilization position into the storage position.
  • the first rod and the second rod are also arranged such that they intersect each other during the entire pivoting movement of the plate members from the utilization position into the stowage position.
  • the first rod and the second rod also cross each other in the utilization position and in the stowage position. Due to the crosswise arrangement of the first and second rod can be advantageously achieved that the first support and the second support in the stowage of the plate parts, in other words, in the folded state of the table are aligned in the same way to the ground as in the utilization position, ie the unfolded state of the table.
  • the rods crossing each other make it possible to achieve a dead center situation between the utilization position and the stowage position.
  • an approximation to the dead center situation can initially take place, and then an overrun of this.
  • the configuration may approach the position of the dead center during pivoting of the plate parts in the direction of the utilization position, wherein the latter is in turn passed over.
  • first axis and the second axis are arranged spaced from each other. This makes it possible to abut the first and second plate parts in the use position in a clean and aesthetic as well as narrow joint, while at the same time the first axis at a small distance from the first plate member and the second axis are arranged at a small distance from the second plate member can. At the same time, space is created between the first and the second plate part for accommodating the bars and the supports in the stowed position of the plate parts, and a substructure for the plate parts, for example involving trusses, profiles, carrier elements or housings, can be slender.
  • the fifth axis and the sixth axis are arranged spaced from each other.
  • a particularly simple transmission can be used for synchronizing the motion sequence, for example a gear with gears rotatably mounted about the fifth and the sixth axis or gear segments.
  • the first axis, the sixth axis and the fourth axis can occupy a position relative to one another during the pivoting of the plate parts between the utilization position and the stowage position in which the first, sixth and fourth axes are arranged in a first plane , The first, sixth and fourth axes are then within the first level.
  • the second axis, the fifth axis and the third axis can assume a position relative to one another during the pivoting of the plate parts between the utilization position and the stowage position in which the second, fifth and third axes are arranged in a second plane, in other words to lie in the second level.
  • the dead center situation is selected in such a way that even a slight deflection of the first and second plate parts from the stowage position does not lead to the dead center situation being exceeded, and the plate parts disturbed in this way automatically return to the stowage position by themselves. It then requires a deliberate action by an operator to bring the plate parts of the table in the utilization position. It is advantageous in this improvement of the invention not necessary to provide an additional locking device to lock the plate parts in the stowed position.
  • first plane and the second plane are inclined to each other. This can be avoided, for example, that the first support and the second support in the stowage of the plate parts engage with each other. This allows, for example, with space-saving construction of the supports nevertheless a stable even in the stowage table. In addition, a symmetrical design and opposing arrangement of the supports is possible, which may also be advantageous for aesthetic reasons.
  • first axis, the second axis, the third axis, the fourth axis, the fifth axis and the sixth axis are arranged substantially parallel to each other. This allows a simple, manageable for the operator folding without the risk of jamming.
  • the first axis is symmetrical about the second axis
  • the third axis is symmetrical about the fourth axis
  • the fifth axis is symmetrical about the sixth axis.
  • the first plate part is formed symmetrically with respect to the second plate part with respect to this plane of symmetry.
  • the first support may be formed symmetrically with respect to the second support with respect to this plane of symmetry.
  • the transmission is designed as a form-fitting acting gear.
  • the transmission couples the pivoting movements of the first and second rods relative to the transmission carrier with each other by means of a toothing.
  • Such a transmission makes it possible to couple the pivoting movements of the two rods with respect to the gear carrier without slippage.
  • misalignments of the first and second plate parts, the first and second rods and the first and second supports and the gear carrier to each other even with multiple folding and unfolding of the table can be avoided.
  • the transmission has two gear segments in engagement with each other.
  • a first of the gear segments about the fifth axis is rotatably mounted on the transmission carrier.
  • An end portion of the first rod is fixed to the first gear segment, and an end portion of the second rod is fixed to the second gear segment.
  • the first support and the second support each have a foot section.
  • the respective foot section is provided with one or more rollers, which are intended to carry the table rollingly displaceable.

  • the rollers are each pivotally coupled about a pivot axis with the foot portion of the associated support, wherein the pivot axes of the rollers provided on the first support and those on the second support in the use position and in the storage position are aligned substantially parallel to each other.
