を提供することを目的とする。Therefore, in order to be usable regardless of the installation location during assembly, that is, the left side of the bed should be moved toward the wall or the right side should be moved. In this case, the switching means needs to be attachable in both the left and right directions so that it can be installed in either case. Further, since the switching means cannot obtain a clear operation feeling (mechanical click feeling) from the mechanism structure, it cannot be reliably detected whether or not the switching has been performed. Was lacking. The present invention has been proposed in order to solve such inconvenience. For example, in a back-knee interlocking switching mechanism provided on a bed or the like having a back-raising function and a knee-raising function, a clear operational feeling can be obtained for the mechanism structure. In addition, an object of the present invention is to provide a back-knee interlocking switching mechanism in which a bed or the like is installed in consideration of an arrangement so as not to restrict installation.

大きい。Next, when only the back is to be raised, a snap operation is performed so that the grip portion 22 of the switching lever 19 is grasped and bent downward. Then, the lever 13 is moved to the torsion coil spring 2.
The pin member 16 is displaced clockwise around the rotation axis p against the urging force of 0, and is attached to the end of the activation arm 15.
Is disengaged from the concave portion 17 of the lever 13 and becomes freely movable in the elongated hole 14 of the guide member 12 (see FIG. 6).
Even if the back raising operation is performed, the interlocking rod 10 and the activation arm 15 projecting from the shaft 9a of the knee raising link 9 are in a state where the interlocking state is cut off, so that only the back raising operation can be performed. Since the above-described back-knee interlocking switching mechanism 11 is disposed on the support frame 5 below the foot side of the bottom 2 of the home bed 1, the home bed 1 can be moved to either side of the room wall. There is a large degree of freedom in installation, such as being able to place it.
