(See FIG. 6).

The foot bottom 11d of the bed apparatus 6 is provided with a foot side mattress stop 21 having a mattress displacement prevention function (see FIGS. 1 and 2).
The foot-side mattress stop 21 is provided to support the end of the mattress 12 placed on the foot bottom 11d of the bed so as not to be displaced, and is formed by bending a rod-shaped member on the end surface of the mattress 12 in the longitudinal direction. It has a U-shaped contact portion 21a and foot portions 21b and 21b that contact each other. These foot portions 21b and 21b are bent at right angles parallel to each other from the abutment portion 21a (referred to as a horizontal portion H), then bent at right angles from a predetermined location (referred to as a vertical portion V), and further, the distal end side is The return portion 21c is bent at a right angle (see FIG. 7).

It is connected. The bottom unit 11U has a large number of through holes 25 arranged at appropriate intervals. The support frame member 24 passes through one of the through holes 25 and passes through the foot portions 21b and 21b of the foot side mattress stop 21 near the foot bottom 11d of the support frame members 24 and 24. The locking holes 26, 26 are formed.
The dimension between the pair of legs 21b is set to be slightly larger than the dimension between the locking holes 26 in the support frame members 24, 24.

The bed apparatus 6 concerning this invention is comprised as mentioned above, and demonstrates the effect | action below.
The mattress 12 placed on the bottom 11 is displaced in the longitudinal direction and the width direction by the user getting on and off the mattress 12 or by adjusting the inclination of the bottom 11. These shifts are blocked by the protrusion 15 on the side face of the bed frame 10 attached to the headboard 14, the foot end mattress stop 21 near the footboard 27, and the side slip prevention member 16 on the side face of the bottom. .

First, when the mattress 12 is placed on the bottom 11 on the projecting surface portion 15 of the headboard 14 facing the back bottom 11a, the end of the mattress 12 comes into contact. At this time, since the projecting surface portion 15 is formed in a planar shape, the end portion of the mattress 12 hits the projecting surface portion 15 evenly. Thereby, even when the mattress 12 is displaced from the back bottom 11a on the head side in the longitudinal direction when the bed is used, particularly when the bottom inclination is adjusted, it can be suitably suppressed (see FIGS. 2 and 3).
Further, even when the user is lying on the mattress 12, the end of the mattress 12 is in contact with the projecting surface portion 15 of the headboard 14, so that there is no gap between the headboard 14 and the mattress 12. When the air flows into the user's head from between the headboard 14 and the mattress 12, it is possible to cut off the breeze that is uncomfortable and flows.

Further, the lateral displacement of the mattress 12 occurs particularly when the user gets on and off the bed side surface. This lateral displacement can be prevented by lateral displacement preventing members 16 attached to the end caps 13 at both ends in the bottom width direction of the waist bottom 11b at the center of the bed apparatus 6 (see FIGS. 1 and 4).
The lateral displacement prevention member 16 can be easily attached to the end cap 13 of the waist bottom 11b via two sets of hooks 18f and holding arms 18a. That is, the hook 18 f in the lateral displacement prevention member 16 enters a hook receiving hole 19 a provided on the upper edge side of the end cap 13, and then the holding arm 18 a in the lateral displacement prevention member 16 is provided on the lower edge side of the end cap 13. The lateral displacement prevention member 16 can be held so as not to rattle against the cut hole 19b (see FIG. 5).

The lateral displacement prevention member 16 mounted as described above hits the side surface of the mattress 12, and lateral displacement is suitably prevented.
Then, the bottom undulation mechanism is operated to adjust the inclination of the bottom 11.
Then, the inclined back bottom 11a and knee bottom 11c can be seen through the arc-shaped edges 16E and 16E on both ends of the upper side of the longitudinal side of the lateral displacement prevention member 16.
Here, inside the arcuate edges 16E and 16E, inclination angle indicating recesses 20 and 20 that are developed within a range of approximately 90 ° are provided, and the inclination angle indicating recess 20 has an angle of 0 to 75 °. Since the angle scale is given in the range, the inclination angles of the back bottom 11a and the knee bottom 11c seen through the arcuate edges 16E and 16E can be easily grasped (see FIG. 6).

Further, the shift of the mattress 12 to the foot side in the longitudinal direction can be prevented by the foot side mattress stop 21 on the bottom end side close to the foot board 27.
The foot-side mattress stop 21 is locked in a state where the abutting portion 21a is lying on the bottom 11 before use, that is, when it is newly loaded (see FIGS. 8 and 9). ).
At this time, the second locking grooves 23 formed in the horizontal portion H of the foot portion 21b of the foot side mattress stop 21 are both crossed by the support frame members 24, 24 on the back side of the foot bottom 11d and the foot bottom 11d. In the through hole 25, the support frame members 24, 24 on the side that can be seen through the through hole 25 are engaged with the engaging holes 26 on the side of the supporting frame members 24, 24 while being biased outward in the bottom width direction. Thus, since the foot side mattress stop 21 can be packed and transported in the state of being attached to the bottom 11, it is not necessary to separately store and manage the foot side mattress stop 21 like other accessory parts.

In use, first, the pair of foot portions 21b, 21b of the foot side mattress stop 21 are pressed so as to be close to each other, and the second locking groove 23 of the horizontal portion H is formed from the locking hole 26. By removing the first locking groove 22 in the vertical portion V of the foot portion 21b in the locking hole 26, the return portion 21c is oriented in the bottom longitudinal direction on the back side of the support frame members 24, 24, The vertical portion V is held in a state of penetrating the bottom in the vertical direction, and further the horizontal portion H is held in contact with the bottom upper surface. At this time, the U-shaped contact portion 21a is held in a state oriented in the bottom width direction and along the footboard 27 side end surface of the foot bottom 11d (see FIG. 10).
Since the dimension between the pair of feet 21b is set to be slightly larger than the dimension between the locking holes 26 in the support frame members 24, 24, the first locking groove 22 in the foot 21b is The locking hole 26 is locked in a state of being biased outward in the bottom width direction and cannot be easily removed. For example, even if the groove portion 22 is detached from the locking hole 26, the leg portion 21b can be prevented from falling off the locking hole 26 by the return portion 21c (see FIG. 11).
