Definitions

  • the invention relates to a convertible furniture, i.e. a piece of furniture which can be changed into another piece of furniture.
  • the invention is especially related to a furniture which can be converted from a bed to a table and vice versa.
  • Patent publications US 60339 A, HU 195416 B, FR 1420300 A, US 277637 A and US 4277856 A show pieces of furniture that can be arranged either as a table or as a bed.
  • the prior art solutions are complex and difficult to use.
  • a convertible furniture according to the invention can be converted between a table and a bed.

  • first and the second furniture parts comprise a frame with first and second end supports.
  • the at least one bed and/or at least one table part are supported on the frames.
  • one of the furniture parts comprises no end supports.
  • one of the furniture parts is a support structure without a table part or a bed, e.g. a plate or a panel that is arranged to be attached to e.g. a wall.
  • first and the second furniture parts are arranged to support a bed and a table part.
  • This provides for a furniture with two beds.
  • the two beds are arranged side by side in the bed position, i.e. the furniture provides for a double bed.
  • the first and second table parts are arranged horizontally, thereby forming a horizontal table surface, and the beds are unusable;
  • the beds are usable forming a double bed, and the table parts are not usable.
  • the convertible furniture comprises a table lock arranged to secure the first and second furniture parts in the table position.
  • the lock is adapted to be moved with an actuator between a locked position, securing the furniture parts in the table position and an open position, allowing movement of the furniture parts towards the bed position.

  • the shaft may extend from the lock at the middle of the table and past the bed under the table part all the way close to the outer edge of the table part.
  • a sideways turnable relatively long lever facilitates the use of the lock.
  • the shaft may be a lever turning around a pivot point.
  • One or more wheels are attached to the end supports.
  • the wheels may be partly hidden, i.e. only a part of the wheel is visible, i.e. the wheels protrude over an edge of the end support.
  • the wheels ease the movement of the furniture against a floor or other support beneath it.
  • these wheels are situated in table position at the lower outer corner of the end supports. More advantageously the wheels are at the corners but protrude only over vertical end support edges.
  • the pivoting means between the furniture parts are constructed in such a way that in bed position, no part or no moving part of the pivoting means reaches over the upper edges of the end supports. This makes the use of the furniture safe and comfortable.
  • Movable extra supports to be engaged with the floor or other support are arranged under a table part e.g. on to the end support.
  • the support When preparing to move the furniture into bed position, the support is engaged with the end support edge that is meant against the floor in bed position. Now, the support will engage the floor.
  • the weight of the furniture in bed position rests on possible wheels and at least partly on the extra supports. There may be more of these extra supports on different points of the furniture.

  • the hinge structure is an important if not the main support structure between the two halves of the furniture when they are moved between the table and bed positions. Strength and robustness of the hinge arms is important. They may be made e.g. of a metal such as steel, plastic or some other suitable material.
  • All the pivoting means, such as the hinges or gas springs, as well as the wheels need to be robust enough to support movement of the furniture parts. Also, the supporting of these parts to the furniture parts needs to similarly robust. One good possibility is to arrange them supported on one or more relatively large support plates, which are easy to attach e.g. on the end supports of the furniture parts.
  • the support plate may be made of e.g. metal, such as steel or aluminium plate or any suitable plastic or composite material. Every piece of pivoting means, e.g. hinges or gas springs may have their own support plates on each furniture part. Also, each wheel may be supported on its own support plate.

If the support plate 16a, 16b is attached at an inner side face of the end support 12a, 12b, at least some of the movable pivoting means, e.g. one of the hinge arms, may need a cavity inside the end support 12a, 12b, to provide space for its moving. Also the wheels 14a, 14b need a cavity inside the end support 12a, 12b.
  • the hinge structure is an important if not the main support structure between the two halves of the furniture when they are moved between the table and bed positions. Strength and robustness of the hinge arms 5a and 5a’ is therefore important. They may be made of a metal such as steel, plastic or some other suitable material.
  • Feet or other supports may be arranged in panel edges so that they contact the floor in table and bed positions. These feet or other supports may give extra friction between the furniture and the floor in order to prevent the furniture from unwanted rolling.
