Description

  The present invention relates to a bottom fixing structure of a bed apparatus that fixes a bottom of a bed to a frame.

  A bed that performs ups and downs such as raising the back and legs for nursing care and medical care can divide the bottom into multiple parts, for example, the back bottom, the waist bottom, the knee bottom, and the foot bottom, and bend them mutually. A basic configuration is such that they can be bent by connecting them or by pivotally supporting a part of them on a frame that supports the bottom.

  It is necessary to fix the bottom to the frame so that the bottom moves following the up and down movement of the bed and does not shift. For example, as disclosed in Patent Document 1, there is a method of fixing the bottom to the frame using a pin or the like.

  FIG. 6 is an explanatory diagram for fixing the bottom to the frame with pins. This figure is a view from the bottom of the bed. The frame 101 has through holes for pinning on the side surfaces. On the other hand, a protruding piece 104 provided with a fixing hole 103 is also formed in the bottom 102 at a position corresponding to the through hole. When assembling the bed, the user positions the positioning member (not shown) on the back surface of the bottom 102 by placing it on a predetermined position of the frame. Then, looking at the lower side of the side surface of the bed, it is confirmed that the through hole of the frame 101 and the fixing hole 103 of the bottom 102 are aligned, and the L-shaped pin 105 is inserted. As shown in FIG. 6B, when the L-shaped pin 105 passes through the protruding piece 104 of the frame 101 and the bottom 102, the snap pin 106 is attached and fixed.
