The cylindrical member 38 is attached to the upper end of the vertical member 33 so as to be rotatable and detachable. A rotation adjusting screw 42 is screwed onto the vertical member 33 from the upper end surface of the cylindrical member 38. A grip 41 having a sufficiently large diameter as compared with the screw 42 is provided at the rear end of the rotation adjusting screw 42. If the rotation adjusting screw 42 is loosened, the horizontal member 34 can be rotated with one end provided with the cylindrical member 38 as a fulcrum, and if it is screwed in, it is fixed in a non-rotatable state at a predetermined position.

  As shown in FIG. 4, a strip-shaped receiving member 43 is fixed to the horizontal member 34 at the middle part and the other end part in the longitudinal direction of the horizontal member 34, and the horizontal member 34. It is provided along the direction that intersects. A rectangular table 44 is placed on the pair of horizontal members 34 and fixed by screws 45.

  A base end portion of a flexible shaft 46 is attached to one side portion of the table plate 44 in the middle portion of the horizontal member 3. An illumination lamp 47 is provided at the tip of the flexible shaft 46. The illumination lamp 47 can change the illumination direction freely by deforming the flexible shaft 46.

  According to the bed apparatus having such a configuration, the movable member 14 is released from the fixed state by the stopper 21 by rotating the lever 25, the movable member 14 is moved along the guide member 12, and the table plate 44 is moved to the user. Position it at an easy-to-use position.

  Next, the lever 25 is rotated to fix the movable member 14 to the guide member 12 so as not to move. Next, the height position of the vertical member 33 of the attachment member 32 is adjusted with a height adjustment screw 36 so that the user can easily use it.

  If necessary, the rotation position of the table plate 44 in the horizontal direction is adjusted by the rotation adjustment screw 42 to a position that can be easily used by the user. In such a state, the user uses the table plate 44 by placing items such as tableware and books on the upper surface of the table plate 4.

  A mounting member 32 composed of a vertical member 33 and a horizontal member 34 holding the table plate 44 is provided integrally with the bed frame 1. Therefore, even if an inadvertent external force is applied to the mounting member 32, the table plate 44 can be prevented from moving with respect to the bed frame 1. Therefore, since the articles placed on the table plate 44 can be prevented from falling, the table plate 44 can be used satisfactorily in a stable state.

  The movable member 14 provided with the attachment member 32 can be moved along the guide member 12. Therefore, when the bed apparatus is used in a back-up state in which one end portion of the mattress 5 located on the headboard 3 side is raised, a position where the user can easily use the movable member 14 according to the back-up angle. It can be moved to and used.

  The horizontal member 34 to which the table plate 44 is attached is provided such that it can rotate in the horizontal direction with respect to the vertical member 33 and can be fixed by a rotation adjusting screw 42 at a predetermined rotational position. Therefore, when the user gets off the mattress 5 or does not use the table plate 44, the movable member 14 provided with the attachment member 32 is moved to the footboard 4 side along the guide member 12 as shown in FIG. If the table plate 44 is rotated from the upper side of the mattress 5 to the side, the table plate 44 and the mounting member 32 can be retracted so as not to disturb the user.

  When the table plate 4 is used, the movable member 14 movably provided on the guide member 12 is fixed to the guide member 12 by the stopper 21 so as not to move. However, the table plate 4 may be used without being fixed. Since the attachment member 32 is provided integrally with the bed frame 1, even if an unintentional external force is applied to the attachment member 32, it is possible to prevent the table plate 44 from moving greatly.

  Further, an illumination lamp 47 is attached to the horizontal member 34 by a flexible shaft 46. Therefore, the position of the illuminating lamp 47 can be changed to a position that the user can easily use by deforming the flexible shaft 46, for example, a position that can reliably illuminate the upper surface of the table plate 44 according to the back raising angle. .

  FIG. 10 is a perspective view of a bed apparatus showing a second embodiment of the present invention. This 2nd Embodiment is a modification of the attachment member which attaches the table board 44 to the bed frame 1 so that a movement is possible.

  That is, in this embodiment, a guide member 12 (only one is shown) is provided on each of the pair of side members 2 of the bed frame 1. Each guide member 12 is provided with a movable member 14 having the same configuration as that of the first embodiment. That is, each movable member 14 is provided with a roller 19, a stopper 21 and a short pipe 31.
