Definitions

  • the present invention relates to a bed system according to the preamble of the first claim, as well as the use of such a bed system.
  • WO2010037415 also describes a bed system.
  • This bed system comprises a mattress supporting structure.
  • the mattress supporting structure in turn comprises an upper surface for receiving a mattress, a chassis and an intermediate layer between the upper surface and the chassis.
  • the intermediate layer is arranged for resiliently supporting the mattress on the upper surface, and for that purpose is provided with at least one spring means, in this case a plurality of springs mounted with their spring direction pointing up.
  • the chassis is arranged to support the entirety of the intermediate layer and the mattress on the upper surface on a floor.
  • Such a mattress supporting structure is sometimes referred to as a box spring.
  • the circumference of the chassis is delimited by first and second longitudinal sides and first and second transverse sides, wherein the first longitudinal side is mounted opposite the second longitudinal side and the longitudinal sides are connected to each other by the transverse sides, wherein the first transverse side is mounted opposite the second transverse side.
  • the chassis further comprises at least one transverse beam.
  • the transverse beam is mounted between the first and second longitudinal sides, with a first transverse end of the transverse beam at the first longitudinal side and a second transverse end of the transverse beam at the second longitudinal side.
  • the transverse beam is mounted rotatably about a rotational axis according to the lengthwise direction of the transverse beam.
  • the transverse beam can be rotated between different rotational positions, of which at least a first and a second differ from each other.
  • the spring means according to WO2010037415 are arranged on the chassis in such a way that they are supported at their bottom side by the transverse beam, and they extend according to their spring direction to the upper surface.
  • the transverse beam in particular the circumference of the transverse beam in the circumferential direction of the transverse beam, is delimited by at least one longitudinal face and a second longitudinal face which are mutually different.
  • the first longitudinal face constitutes a first supporting face for at least one spring
  • the second longitudinal face constitutes a second supporting face for the same spring.
  • the first supporting face supports the spring means in the first rotational position of the transverse beam
  • the second supporting face supports the spring means in the second rotational position of the transverse beam.
  • the first and second supporting faces are at different distances from the rotational axis, allowing the height of the bottom of the spring to be adjusted relative to the chassis.
  • This adjustment of the bottom of the spring allows the supporting characteristics of the upper surface to be adjusted for the mattress, and thus allows the support for a person lying on the mattress to be adjusted.
  • This adjustment allows the support for a person on a mattress to be individualized, offering the person a better support during sleep. Thus, for instance, back problems, sleeping problems etc. can be taken care of.
  • the rotation of the transverse beam according to WO2010037415 is not limited.
  • the transverse beam can therefore be rotated several times clockwise or counter-clockwise.
  • the entire circumference in the circumferential direction of the transverse beam has to be provided to support the spring, and the transverse beam also has to be suspended in a freely rotatable way in the chassis.
  • specific requirements were made of the suspension of the transverse beam in the rest of the chassis, and for instance to the shape of the transverse beam.
  • the transverse beam and the suspension for instance have to be able to resist bending forces when the transverse beam, suspended in a freely rotatable way, has a load placed on it by a person on a mattress on the upper surface.
  • Specific demands are also made of the circumference of the transverse beam in the circumferential direction, at least in the places where a spring means is supported.
  • the mattress supporting structure comprises
  • the intermediate layer is arranged for at least partly resiliently supporting the mattress on the upper surface.
  • the chassis is arranged to support the entirety of the intermediate layer and the mattress on the upper surface, resiliently supported by the intermediate layer, on a floor.

  • the transverse beam is mounted between two opposing sides of the circumference of the chassis.
  • the transverse beam is rotatable about a rotational axis according to the lengthwise direction of the transverse beam mounted between the two opposing sides of the circumference of the chassis.
  • the transverse beam is furthermore rotatable between a first rotational position and a second rotational position different from the first rotational position.
  • the rotational positions are characterized, for instance, by a position of the transverse beam around the rotational axis that can be expressed in degrees or radials relative to a reference point.
  • the reference point may be freely chosen.
  • the intermediate layer comprises at least one spring means which extends, supported at its bottom by the transverse beam, along the spring direction between the transverse beam and the upper surface.
  • the spring means is for instance a spring, in particular a pocket spring, where the spring is housed in a pocket.
  • the transverse beam preferably the circumference of the transverse beam, more preferably the circumference of the transverse beam in the circumferential direction of the transverse beam, is delimited by at least a first face and a second face different from the first face.
  • the first and second faces are longitudinal faces.
  • the first face constitutes a first supporting face and the second face constitutes a second supporting face, wherein the first supporting face supports the spring means in the first rotational position of the transverse beam and the second supporting face supports the spring means in the second rotational position of the transverse beam.
  • the first and second supporting faces are at different distances from the rotational axis, so that the height of the bottom of the spring means relative to the chassis can be adjusted.
  • the first and second rotational positions are terminal rotational positions.
  • first and second rotational positions are terminal rotational positions, and moreover the first and second rotational positions are also different, a rotational range of positions that cannot be taken up by the transverse beam is created between the two rotational positions.
  • at least a part of the beam does not need to be adapted to support the at least one spring means, allowing, for instance, means that strengthen the transverse beam to be provided in that location, so that the transverse beam can resist the bending forces caused by stress.
  • the transverse beam comprises retaining means to prevent the rotation of the transverse beam beyond the first and second positions. These retaining means help to ensure that the transverse beam cannot be rotated beyond the terminal rotational positions.
  • the retaining means comprise first and second blocking parts.
  • the first blocking part prevents rotation of the transverse beam beyond the first rotational position by abutting against a third blocking part of the chassis.
  • the second blocking part prevents rotation of the transverse beam beyond the second rotational position by abutting against a fourth blocking part of the chassis.
  • the transverse beam is further delimited, more preferably in the circumferential direction, by a third, preferably longitudinal, and a fourth, preferably longitudinal, face.
  • the first blocking part preferably comprises the third face and the second blocking part preferably comprises the fourth face.
  • Such third and fourth longitudinal faces allow the first and second blocking parts to be integrated into the shape of the transverse beam, further simplifying the assembly of the transverse beam in the chassis.
  • the first and/or second blocking parts comprise at least one protrusion that extends relative to the respective third and/or fourth faces. Such blocking parts can further prevent the transverse beam from rotating beyond the terminal rotational positions.

  • the first and second supporting faces are adjacent. It was found that such a shape of the transverse beam is easy to manufacture.

  • the chassis comprises a supporting face.
  • the supporting face may for instance be formed by a series of slats, a grid, a plate, preferably a substantially solid plate or a solid plate, or a combination of more than one of these.
  • the supporting face can for instance be made of wood, although other materials, such as for instance plastic, metal, etc. are also possible.
  • the curved surface is provided to slide over the supporting face when rotating the transverse beam.
  • Providing such a configuration allows support of the transverse beam to be provided by the supporting face, as a result of which the transverse beam will be less subject to bending stresses, as the transverse beam will be subjected more to compression stresses.
  • the transverse beam is provided with the curved surface over substantially its entire length, and the transverse beam is thus supported by the supporting face over substantially its entire length, allowing the bending load of the transverse beam to be further reduced.
  • the suspension of the transverse beam can also further be simplified. This, for instance, a simple snap connection can be provided, both in the longitudinal direction and to for instance maintain the transverse beam in discrete rotational positions, as this connection is subjected to fewer forces.
  • first and second rotational positions are terminal rotational positions, and moreover the first and second rotational positions are also different, a rotational range of positions that cannot be taken up by the transverse beam is created between the two rotational positions. This range can for instance be taken up by the curved surface.
  • the chassis comprises respective first and second bearings for rotatably receiving a first end of the transverse beam and a second end of the transverse beam, respectively.
  • Such bearings are easily provided and further simplify the construction.
  • the first and/or second bearings are for instance gliding bearings or a roller bearing, for instance a ball bearing.
  • the bearings and the transverse beam are mounted onto the supporting face.
  • the supporting face thereby forms the third and fourth blocking parts.

  • the bed system comprises means for providing a visual indication of the rotational position of the transverse beam.
  • the visual indication shows the user in a simple manner that a particular rotational position has been reached.
  • the circumference of the chassis is delimited by first and second longitudinal sides and first and second transverse sides.
  • the first longitudinal side is mounted opposite the second longitudinal side and the longitudinal sides are connected to each other by the transverse sides, wherein the first transverse side is mounted opposite the second transverse side.
