Abstract
The folding bunk beds of this invention fold between a horizontal sleep position and a vertical storage position. The various embodiments, both manually operated and power operated, of the folding bunk beds use vertically shifting pivot points to accommodate larger bed decks. The bed decks are hinged to carriages that slide on vertical shafts mounted within a wall frame. Bed decks are mounted to support arms that are pivotally connected to the carriages. A linkage mechanism or guide track allows the bed decks to pivot simultaneously between a horizontal sleep position and a vertical storage position as the carriages shift along the shafts. The vertically shifting pivot point allows the bed decks to kneel down, that is to fold up at a pivot point lower on the wall.
Claims20
A folding bunk bed mounted to a vertical wall comprising:
- an upright mountable to the vertical wall and having an elongated interior defined therein;
- a vertical shaft mounted longitudinally within the upright interior,
- a carriage mounted to the shaft for reciprocal movement along the length of the shaft within the upright interior;
- a first deck pivotally connected to the carriage;
- a second deck pivotally connected to the carriage and spaced below the first deck;
- and
- a linkage pivotally connected between the upright and one of the first deck and second deck such that the first deck and second deck pivot simultaneously between a substantially horizontal sleep position and a vertical storage position as the carriage moves along the length of the shaft.
A folding bunk bed mounted to a vertical wall comprising:
- a frame mountable to the vertical wall;
- a first track arm and a second track arm extending outward from the frame, each of the first track arm and the second track arm having an elongated slot;
- a vertical shaft mounted to the frame,
- a carriage mounted to the shaft for reciprocal movement along the length of the shaft;
- a first deck pivotally connected to the carriage;
- a second deck pivotally connected to the carriage and spaced below the first deck;
- the first deck having a roller shiftably disposed within the slot of the first track arm and the second deck having a roller shiftably disposed within the slot of the second track arm such that the first deck and second deck pivot simultaneously between a substantially horizontal sleep position and a vertical storage position as the carriage moves along the length of the shaft.
A folding bunk bed mounted to a vertical wall comprising:
- a frame mountable to the vertical wall, the frame includes an upright having an elongated interior defined therein and a longitudinal slot therein;
- a vertical shaft mounted to the frame, the shaft disposed longitudinally within the upright interior;
- a carriage mounted to the shaft for reciprocal movement along the length of the shaft, the carriage shiftably disposed within the upright interior;
- a first deck pivotally connected to the carriage, the first deck includes a support arm pivotal to the carriage and extending outward from the upright through the upright slot;
- a second deck pivotally connected to the carriage and spaced below the first deck;
- and
- a linkage pivotally connected between the frame and one of the first deck and second deck such that the first deck and second deck pivot simultaneously between a substantially horizontal sleep position and a vertical storage position as the carriage moves along the length of the shaft.
