  Accordingly, a gap indicated by d in FIG. 2 is formed by the difference in the width dimension between the side fence 11 and the back floor portion 7a located at the site where the side fence 11 is provided. When the back floor portion 7a, which is a movable member, is driven in the raising direction by the gap d, the user's body, for example, a hand, is placed between the widthwise end of the back floor portion 7a and the inner surface of the side rail 11. It is designed to prevent pinching.

  Even when the side fence 11 is provided at the other end in the width direction of the one end 3a of the bed body 1 or the side of the other end 4a in the longitudinal direction, a similar gap d is formed, The body is prevented from being pinched strongly between the floor board 7a and the second customer member 7e.

  The back floor portion 7a and the waist floor portion 7b, and the first leg floor portion 7d and the second leg floor portion 7e are rotated by a pair of rotating levers 9a (in FIG. Only one rotating lever 9a located on the side is driven up and down.

  Therefore, when each floor portion is driven in the downward direction by the drive mechanism 9, even if a body or an object is sandwiched between the lower surface of the floor portion or between the floor portion and the side rail 11, the floor portion is raised. Since the body is freely displaced in the direction, the sandwiched body is not strongly pressed.

  On the upper surface of the floor plate body 7, a mattress 14 configured to be bendable by a material such as urethane or fiber indicated by a chain line in FIGS. 1 and 2 is placed. The width dimension of the mattress 14 is set to be larger than the width dimension of the floor plate body 7 and smaller than the width dimension of the one end portion and the other end portion 4a of the bed main body 1.

  On the both sides in the width direction of the central portion in the longitudinal direction of the bed main body 1, a detent means 15 is provided. This slip prevention means 15 has a holding body 16 as shown in FIGS. The holding body 16 has a hollow accommodating portion 17 formed at one end in the front-rear direction, and the mounting piece 18 extends from the upper surface of the accommodating portion 17 toward the other end in the front-rear direction at the same height as the upper surface. Has been issued. As shown in FIG. 4, the attachment piece 18 is set to have a width dimension shorter than that of the housing portion 17.

  A slit 19 is formed in the upper surface of the housing portion 17 over substantially the entire length in the width direction. The slit 19 has a plate-like shape, and a slip prevention member 21 whose upper end is curved into a convex arc is movable in the vertical direction. Has been passed. A bag-like first holding portion 22 having an open bottom surface is provided on one side surface at both ends in the width direction of the lower end portion located in the housing portion 17 of the slip prevention member 21.

  A pair of bag-like second holding parts 23 (shown in FIGS. 5 and 6) whose upper surfaces are opened are provided on the inner bottom part of the housing part 17 facing the pair of first holding parts 22. Both ends of a spring 24 as an urging member are accommodated and held in the first and second holding portions 23 of each pair facing each other.

  The spring 24 elastically biases the displacement preventing member 21 in the upward direction. Accordingly, the upper end of the shift prevention member 21 protrudes from the slit 19. The slip prevention member 21 urged in the upward direction by the spring 24 is positioned opposite to the side surface of the mattress 14.

  As shown in FIG. 5, when the first holding portion 22 of the slip prevention member 21 rises to the upper limit corresponding to the stopper 25 provided on the inner surface of the upper portion of the housing portion 17, the upper end of the slip prevention member 21 is mattress. It is located at a height of about two-thirds of the thickness of 14.

  Note that the height position of the upper end when the slip prevention member 21 rises between the ascent limits is not limited to two-thirds of the thickness of the mattress 14, but may be more or less than that. It is desirable to be at a position lower than the upper surface of.

  Further, the slip prevention member 21 is prevented from being pulled out from the slit 19 when the first holding portion 22 hits a stopper 25 provided on the inner surface of the upper wall of the housing portion 17 at the upper limit. Yes.

  As shown in FIGS. 5 and 6, the holding body 15 of the shift preventing means 15 having the above-described configuration is configured such that the mounting piece 18 is attached to the upper surface of the end in the width direction of the fixed floor portion 7 c of the floor plate body 7. It is fixed and provided.

  Accordingly, the accommodating portion 17 of the holding body 16 is located in the concave portion 6 of the bed body 1 as shown in FIG. 2, and the lower surface of the portion of the mattress 14 located in the concave portion 6 is shown in FIGS. As shown, the holding body 16 is supported by an inner portion of the upper surface than the slit 19.

The holding body 16 of the slip prevention means 15 is attached to the upper surface of the fixed floor portion 7c of the floor plate body 7, but may be attached to the upper surface of the bed body 1, that is, the lower surface of the fixed floor portion 7c. In short, the holding body 16 may be attached directly or indirectly to the bed main body 1.

  Further, the displacement prevention member 21 protruding from the slit 19 of the housing portion 17 contacts or faces the side surface of the portion of the mattress 14 located in the recess 6 so that the mattress 14 faces the floor plate body 7. The upper surface of the plate is restricted from moving in the width direction.

  According to the bed apparatus having such a configuration, the mattress 14 placed on the upper surface of the floor plate body 7 is formed in the width direction by the pair of displacement prevention members 21 positioned opposite to both side surfaces in the width direction of the center portion in the longitudinal direction. The movement is limited.

  Therefore, even if the floor portion 7b over the back floor portion 7a or the first and second leg floor portions 7d and 7e is driven up and down, or the user gets on and off the mattress, the mattress 14 is not moved. Shifting in the width direction on the upper surface of the floor plate 7 is prevented.

  The pair of displacement prevention members 21 are elastically biased in the upward direction by the springs 24 and protrude from the slits 19 on the upper surface of the housing portion 17 of the holding body 16. Although the protrusion height of the slip prevention member 21 is lower than the upper surface of the mattress 14 as shown in FIG. 5, the user moves the body to the end in the width direction of the mattress 14 or sits on the end. If the end portion of the mattress 14 is compressed by the weight of the user's body as indicated by an arrow L in FIG. 6, the above-described displacement prevention member 21 hits the user's body.

  When the displacement preventing member 21 is pressed against the user's body, the displacement preventing member 21 is displaced downward while compressing the spring 24. As a result, the upper end of the displacement preventing member 21 is prevented from strongly pressing the user's body, so that the user is prevented from feeling uncomfortable or uncomfortable.

  That is, according to the displacement preventing means 15 having the above-described configuration, it is possible to prevent the mattress placed on the floor board 7 from shifting in the width direction without causing discomfort to the user.

  Concave portions 6 are formed on both sides in the width direction of the central portion of the bed body 1 in the longitudinal direction. Since the caregiver positions his / her body in the recess 6, the user can approach the user who is supine on the mattress 14, so that the user can be easily cared for.

  On the other hand, the width dimension of the mattress 14 is made larger than the width dimension of the bed body 1 in order to prevent the body and the like from being sandwiched between the portion of the floor plate body 7 that is driven up and down and the side fence 11. Both end portions in the width direction of the mattress 14 protrude outward in the width direction from the floor plate body 7. Therefore, when a load is applied to the upper surface of the protruding portion of the mattress 14, it may be easily bent downward. In particular, since the both sides of the central portion in the width direction of the bed main body 1 are formed in the concave portion 6 having a smaller width dimension than the other portions, the support state of the mattress 14 may not be reliable.

  However, the lower surface of the part located in the width direction both ends of the center part in the longitudinal direction of the mattress 14 is supported by the upper surface of the accommodating portion 17 of the displacement preventing means 15. For this reason, the portion corresponding to the concave portion 6 of the mattress 14 is difficult to bend downward, so that the user got down on the mattress 14 from the side of the central portion of the longitudinal service, or touched the side. Stability can be improved.

  In the above embodiment, the floor plate body is divided into a plurality of floor portions and described as an example of the bed apparatus configured to be driven up and down by the drive mechanism. However, the floor plate body provided in the bed body is driven up and down. Even in the case of a structure having no gap, the deviation preventing means of the present invention can be applied.
