Definitions

  • This application relates to a sofa bed, and specifically, to a novel sofa bed iron frame mechanism.
  • a bed is one of essential household items in home life of people. However, a bed usually occupies a large area and often occupies a quite considerable amount of living space.
  • the sofa bed allows people to obtain a larger activity space through conversion between a sofa and a bed, greatly improving space utilization, so that people can enjoy a more comfortable living environment in limited space.
  • An existing sofa bed iron frame mechanism has the following problems in use:
  • a booster spring in an existing bed frame is connected to and passes through an entire side plate, which increases abrasion and wear among the spring, the side plate, and a soft decoration part in actual use.
  • the spring passes through the entire side plate, thereby increasing risks in use. For example, a hand may be squeezed and injured by the booster system when being inserted from the portion of the side plate.
  • a backrest When a backrest is configured to be unfolded and in a horizontal state and bears a large load, abrasion occurs between the backrest and the booster system (a spring and a connecting rod), resulting in damage or abrasion and wear of the backrest and the booster system (the spring and the connecting rod).
  • An objective of the present invention is especially to alleviate this situation.
  • This application is intended to overcome defects of the prior art and provides a novel sofa bed iron frame mechanism.
  • the function of conversion between a sofa and a bed is achieved through unfolding and folding of two interrelated sofa bed frames and a rotatable backrest.

  • the entire overturning mechanism is enabled to have a self-locking function in an open state.
  • the first support rod and the second support rod, and the third connecting rod and the back plate connecting member are all in a linear state, thereby avoiding accidental actions of the overturning mechanism.
