  • A mattress is placed on the bed frame to use the bed and the bed is provided with specific functions by improving the bed frame.
  • An example of the bed frame is disclosed in Korean Utility Model Registration No. 20-0436046, titled “Bed frame”, which has been filed by the applicant(s) and registered in Korea.
  • According to this bed frame, a crank is fitted on a shaft of a decelerator, a support member is vertically mounted on the crank, a mattress support frame is disposed on the support member, and three straight sticks are fastened to both sides of the mattress support frame, respectively.
  • Further, the outer ends of the sticks are fixed to the outer frame of the bed frame by ball joints.
  • Further, though not shown in detail in the drawings, the mattress is placed on the three sticks at both sides and the mattress support frame at the center.
  • The configuration of the bed frame described above is briefly described as followings.
  • As the decelerator is operated by a driving unit, such as an electric motor, the crank rotates and operates the support member, in which the support member is vertically arranged, such that it seems to move up/down when seen from a side, and also seems to rotate when seen from the front.
  • Therefore, the mattress support frame at the center turns and the portion corresponding to the waist of the mattress turns, such that the waist is turned. Accordingly, it says that the bed frame is useful for health or medical care.
  • However, the following problems are pointed in the bed frame described above.
  • Although the main object of beds is for users to lie thereon, practically, the users may carefully lie or jump on the beds, or more shock or external force may be applied to the beds. Accordingly, the mattress is pushed to one side by the shock or external force.
  • Further, the part substantially supporting the mattress is the mattress support frame and the six sticks at both sides; however, in this structure, some portions of the mattress floating in the air because the distances between the sticks are large, such that the mattress cannot be stably supported. In particular, there is a problem that a safety accident may occur, such as that the feet is stuck, the users step on the regions between the sticks.
  • On the other hand, when the decelerator is controlled to stop the operation, the decelerator stops at the controlled timing and the mattress support frame is positioned at a specific height. Accordingly, the bed is stopped with the center portion of the mattress rising and it is very inconvenient to normally used the bed with the center portion of the mattress rising as described above.
  • Further, it is very inconvenient to get on/off or lie on the bed with the mattress support frame depressed down.
  • Therefore, the bed frame described above has a difficulty in maintaining the horizontal position when stopping the operation. Accordingly, the horizontal position cannot be ensured and the user feels inconvenience when lying or getting up.
  • Further, although the bed frame can be used for waist exercise or medical care, it has a limit in that it cannot be used as a common bed that is used in normal houses.
