Universal bed system
View Patent ↗An adjustable bed system includes first and second end boards. A first height adjustment mechanism is secured to the first end board via a first mounting member and a second height adjustment mechanism is secured to the second end board via a second mounting member. The second height adjustment mechanism is independent of the first height adjustment mechanism. An external housing member is engagable with one of the first and second mounting members. A transition box is operatively engagable with one of the first and second height adjustment mechanisms. The transition box is positioned within the external housing such that the transition box is substantially inhibited from rotation during height adjustment of the bed system. A drive shaft interconnects the transition box, at a first end thereof, and the other of the first and second height adjustment mechanisms, at a second end thereof.
1. A method of assembling an adjustable bed, comprising:
coupling a first end board to a frame, the first end board including a first height adjustment mechanism;
coupling a second end board to the frame, the second end board including a second height adjustment mechanism;
determining whether the first and second end boards are similar or different;
coupling a transmission box to the first height adjustment mechanism, wherein coupling the transmission box to the first height adjustment mechanism includes:
if the first and second end boards are determined to be similar, coupling a first output of the transmission box to the first height adjustment mechanism; and
if the first and second end boards are determined to be different, coupling a second output of the transmission box to the first height adjustment mechanism; and
coupling a drive shaft between an input of the transmission box and the second height adjustment mechanism.
2. The method according to claim 1 , wherein determining that the first and second end boards are similar includes determining that rotation of drive screws of each of the first and second height adjustment mechanisms effects height adjustment in a similar direction.
3. The method according to claim 1 , wherein determining that the first and second end boards are different includes determining that rotation of drive screws of each of the first and second height adjustment mechanisms effects height adjustment in an opposite direction.
4. The method according to claim 1 , wherein coupling the drive shaft between the input of the transmission box and the second height adjustment mechanism with the first output of the transmission box coupled to the first height adjustment mechanism further includes extending the drive shaft to a first length, and wherein coupling the drive shaft between the input of the transmission box and the second height adjustment mechanism includes with the second output of the transmission box coupled to the first height adjustment mechanism further includes extending the drive shaft to a second, different length.
5. The method according to claim 1 , wherein coupling the drive shaft between the input of the transmission box and the second height adjustment mechanism further includes inserting the drive shaft through a bracket member extending from the frame.
6. The method according to claim 5 , wherein coupling the drive shaft between the input of the transmission box and the second height adjustment mechanism further includes coupling a ring member about the drive shaft adjacent the bracket member to inhibit translation of the drive shaft relative to the frame.
7. The method according to claim 1 , wherein coupling the first output of the transmission box to the first height adjustment mechanism includes moving a door of the transmission box to expose the first output.
8. The method according to claim 1 , wherein coupling the second output of the transmission box to the first height adjustment mechanism includes moving a door of the transition box to expose the second output.
9. The method according to claim 1 , further including coupling a hand crank to one of the first or second height adjustment mechanisms, the hand crank operable to raise and lower the bed frame relative to the first and second end boards.
10. The method according to claim 1 , wherein coupling the transmission box to the first height adjustment mechanism further includes engaging an external housing of the transmission box with a mounting member of the first height adjustment mechanism to inhibit relative rotation therebetween.
