Definitions

  • the present invention relates to a mattress designed to be laid on an adjustable bed used for nursing care.
  • adjustable beds used as turning beds and the like operate to assist postural change of care recipients.
  • the postural change is generally achieved by inclining a part, or the entire mattress of the beds on which care recipients are lying so as to turn the care recipients in the direction of inclination (refer to Japanese Laid-Open Patent Application Publication No. H06-14824).
  • the majority of these types of beds employ a mechanism that tilts the mattress surface from a flat position across the width direction of the mattress in order to assist the postural change.
  • the present invention is a mattress to be laid on a platform of an adjustable bed having a transformable bed surface.
  • a fixture that engages with the platform to secure the mattress is disposed on a surface of the mattress facing the platform.
  • This structure prevents displacement of the mattress from the bed surface, which may occur when the adjustable bed is driven. Consequently, a care recipient in a recumbent position on the bed is able to safely start the postural change from the proper position. In addition, a good, sound sleep is guaranteed by this structure.
  • a mesh may be formed on a front face of the platform, and the fixture secures the mattress by tightly fitting into one or more interstices of the mesh.
  • the fixture may be detachable from the platform. This structure is desirable since it facilitates the mattress replacement and the maintenance of the adjustable bed.
  • the fixture may be disposed, on the surface of the mattress, in a part of the mattress corresponding to a lower back region of a user lying on the mattress. This structure is desirable since it facilitates stretching the mattress when the adjustable bed is driven.
  • An example of adjustable beds applying the present invention includes: the platform of which the front face is flexible; a flex mechanism operable to flex the platform to form a flexion position that includes at least one of a sitting-up position and a knee break; and a tilt mechanism operable to tilt the front face laterally.
  • both the flex mechanism and the tilt mechanism are operable with the other mechanism in operating condition.

  • FIG. 1 is a perspective view illustrating a structure of an adjustable bed 2 according to a first embodiment of the present invention.
  • the adjustable bed 2 is constituted such that a bed frame 10 is disposed on an adjustable stage 20 placed on a fixed stage 30 .
  • the bed frame 10 includes a coupled platform 11 a - 11 d , which is formed by dividing a surface part (i.e. upper surface of the bed) into four sections corresponding to the back, hip, upper-leg, and lower-leg regions of a care recipient's body lying on the bed, and coupling these sections together so as to be freely adjustable.
  • a coupled platform 11 a - 11 d an upper-body member 11 a , a lower-back member 11 b , an upper-leg member 11 c , and a lower-leg member 11 d are each coupled in the given order.
  • the lower-back member 11 b is fixed directly onto the adjustable stage 20 by welding, for example, thus preventing the bed frame 10 from being disengaged from the adjustable stage 20 .
  • Side members 12 Ra- 12 Rd and 12 La- 12 Ld for supporting the care recipient's body from the sides are coupled to the platform 11 a - 11 d on the right and left, respectively.
  • the upper-body member 11 a and upper-leg member 11 c of the bed frame 10 are respectively coupled, via L-shaped couplers 211 and 212 , to the shafts of direct-acting actuators M 1 and M 2 (see FIG. 3 showing a plan view of the bed) disposed on a center beam 21 A of the adjustable stage 20 .
  • the actuators M 1 and M 2 are able to transform the bed frame 10 so that the care recipient is placed in a flexion position (see FIG. 6 showing a bed form; FIG. 8B showing a side view of the bed).
  • a wire mesh is in fact placed over the surface of the coupled platform 11 a - 11 d and side members 12 Ra- 12 Rd and 12 La- 12 Ld of the bed frame 10 .
  • this wire mesh has been omitted from the drawing as well as the following drawings in order to illustrate the structure of the bed with clarity. Consequently, these drawings depict only the frames of the coupled platform 11 a - 11 d and side members 12 Rd- 12 Rd and 12 La- 12 Ld.
  • the coupled platform and side members are not confined to having the wire-mesh surface construction, and may alternatively be composed of coupled pieces of a board material.

  • Fan-shaped members 13 R/ 13 L ( 13 R not shown) are coupled to the edges of the side members 12 Rd/ 12 Ld corresponding to the care recipient's lower-leg region. These members are normally housed in the pockets of the side members 12 Rc/ 12 Lc, respectively. Then, when the bed frame 10 is transformed into a flexion position, the fan-shaped members 13 R and 13 L come out of the pockets to support the care recipient's knee region.
  • the adjustable stage 20 has a rectangular frame construction composed of the center beam 21 A, side beams 21 R and 21 L, and two parallel end bars connected to either end of the center beam 21 A and side beams 21 R and 21 L.
  • rollers 200 , 201 , 202 , and 203 are disposed so as to slide in a y direction on roller slide bars 300 of the fixed stage 30 , as indicated in FIG. 1 .
  • Ladder-shaped side-member support frames 24 R/ 24 L are respectively disposed on the side beams 21 R/ 21 L of the adjustable stage 20 .
  • Each of the ladder-shaped side-member support frames 24 R and 24 L is composed of two bars 22 R/ 22 L and 23 R/ 23 L that run in the same direction as the side beam 21 R/ 21 L, and two connecting bars 231 R/ 231 L and 232 R/ 232 L.
  • the bars 23 R and 23 L have concave sections in the area where the side-member support frames 24 R/ 24 L meet the side members 12 Rb/ 12 Lb, so that the side members 12 Rb/ 12 Lb fit in the space provided by the concave sections (see FIG. 3 showing a plan view of the bed).
  • the adjustable stage 20 is designed in such a way that the side members 12 Rb/ 12 Lb will not interfere, in a thickness direction of the bed, with the side members 12 Ra/ 12 La and the side members 12 Rc/ 12 Lc on either side of the side members 12 Rb/ 12 Lb, when the bed frame 10 is transformed into the flexion position.
  • the bars 22 R/ 22 L are coupled respectively to the side beams 21 R/ 21 L by couplers 236 Ra/ 236 La and 236 Rb/ 236 Lb, allowing the bars 22 R/ 22 L to rotate freely through an axial direction while remaining secured to the side beams 21 R/ 21 L.
  • FIGS. 2A-2C are schematic sectional views of the bed showing the operation of actuators in the vicinity of the adjustable stage 20 and the upper-leg member 11 c of the bed frame 10 .
  • direct-acting actuators M 3 R and M 3 L are symmetrically disposed on the adjustable stage 20 to the left and right of the center beam 21 A (i.e. in the y direction toward the coupling members 236 Ra and 236 La, respectively).
  • the tips of shafts of the actuators M 3 R/M 3 L are coupled to L-shaped members 235 R/ 235 L fixed directly below the rotating bars 22 R/ 22 L.
  • the shafts of the actuators M 3 R/M 3 L extend, and thereby the L-shaped members 235 R/ 235 L and bars 23 R/ 23 L are rotated on the axis of the rotating bars 22 R/ 22 L. Then, the side-member support frames 24 R/ 24 L are raised from the horizontal plane to a position perpendicular to the horizontal bed surface (FIGS. 2 A ⁇ 2 B ⁇ 2 C).
  • Stage bars 27 R/ 27 L are provided on the underside of the side beams 21 R/ 21 L, and tightly fitted into stage-bar bearings 36 R/ 36 L (U-shaped cross-sectional) located to the side of the fixed stage 30 .

  • FIG. 4 is a perspective view illustrating a structure of the fixed stage 30 .
  • the fixed stage 30 includes a rectangular frame 31 .
  • a pair of shorter ends of the frame 31 forms the roller slide bars 300 so that the rollers 200 - 203 of the adjustable stage 20 travel back and forth on them.
  • Side beams 32 R and 32 L of the fixed stage 30 are slide-slot members (square-bracket cross-sectional), and are disposed such that the slide slots face one another.

  • actuators M 4 R/M 4 L are respectively disposed at an angle.
  • parallelogram mechanisms 35 R/ 35 L which are based on horizontal slide mechanisms, are formed on the right and left sides of the fixed stage 30 .
  • the rotating arms 351 R/ 351 L and 352 R/ 352 L move in a circular motion centering on the points at which they are coupled to the side beams 32 R/ 32 L.
  • One ends of the support arms 354 R/ 354 L and 356 R/ 356 L travel back and forth on the inside of the side beams 32 R/ 32 L, while being regulated by the rotating arms 351 R/ 351 L and 352 R/ 352 L.
  • the support arms 354 R/ 354 L and 356 R/ 356 L oscillate in a vertical direction, and thereby the adjustable stage 20 , supported by the stage-bar bearings 36 R and 36 L, and the bed frame 10 are able to move vertically up and down from either or both the right and left sides of the fixed stage 30 . Therefore, the adjustable bed 2 can be elevated even in a small space as a consequence of space saving, while the use of the rollers 200 - 203 and the parallelogram mechanisms 35 R and 35 L realizes space saving even during postural change operations.
  • By driving one of parallelogram mechanisms 35 R and 35 L corresponding respectively to the side beams 32 R and 32 L postural change from the supine to lateral position is achieved.
