Description

  The present invention relates to a mattress, and more particularly to a mattress used in a reclining bed in which a back bottom can be turned upside down.

  Conventionally, in beds that are frequently used for nursing care, etc., a back bottom for supporting the back of a person lying on the bed in a supine position is attached to the base in a tiltable manner. A reclining bed having a drive mechanism interposed therebetween is widely used (for example, see Patent Document 1).

  In this reclining bed, by driving the drive mechanism and raising the back bottom to the base, the back bottom supports the back of a person lying in a supine position through the mattress in an inclined manner on the bed. The upper body can be held in a raised position.

  However, as shown in FIG. 6 (a), in the conventional reclining bed 101, when the back bottom 103 is gradually raised from the base 102, a person lying on his / her back in a supine position is accompanied accordingly. The upper body is also raised gradually, but the center of rotation (base end) of the back bottom 103 and the center of rotation of the mattress 104 do not match, and the center of rotation of the mattress 104 is more than the center of rotation of the back bottom 103. Therefore, the mattress 104 is distorted in the vicinity of the center of rotation of the mattress 104, and the back of a person lying on the back is squeezed to give discomfort.

  This is because the distance between the center of rotation of the back bottom 103 and the center of rotation of the mattress 104 becomes longer and the distortion increases as the thickness of the mattress 104 is increased in order to improve the sleeping comfort.

  Therefore, as shown in FIG. 6B, it is possible to use mattresses 105 and 106 laminated in a plurality of layers instead of simply increasing the thickness of the mattress 104, but in the mattresses 105 and 106 laminated in a plurality of layers, As shown in FIG. 6B, although the upper bottom mattress 105 and the lower mattress 106 are displaced when the back bottom 103 stands up, the occurrence of distortion can be suppressed. If the up and down is repeated, even if the back bottom 103 is laid down, the mattresses 105 and 106 in the upper and lower layers do not return to their original state, and there is a possibility that the back of a person lying on the back is pressed and uncomfortable.

Therefore, according to the first aspect of the present invention, in the mattress used in the reclining bed in which the back bottom can be turned up and down, the upper layer side mattress constituent body and the lower layer side mattress constituent body are laminated in a vertical layer, and the upper layer side mattress The left and right side portions of the structure and the left and right side portions of the lower layer mattress structure are connected to each other between a position that is a predetermined distance away from the top of the head and a position that is a predetermined distance away from the toe, and is separated from the top of the head by a predetermined distance. The position was determined to be closer to the top of the head than the rotation axis of the base end of the back bottom .

Further, in the present invention according to claim 2, in the mattress used in the reclining bed in which the back bottom can be turned up and down, the upper layer side mattress constituent body and the lower layer side mattress constituent body are laminated in the upper and lower layers, and the upper layer side mattress The left and right side portions of the constituent body and the left and right side portions of the lower layer mattress constituent body are connected between a position that is a predetermined distance away from the top and a position that is a predetermined distance away from the toe portion, and a predetermined distance from the toe portion. The position away from the base end of the lower leg that is pivotally connected to the tip of the upper leg that can be raised and lowered is on the side opposite to the toe .

According to the third aspect of the present invention, in the mattress used in the reclining bed in which the back bottom can be turned up and down, the upper layer side mattress constituent body and the lower layer side mattress constituent body are laminated in a vertical layer, and the upper layer side mattress The left and right side portions of the structure and the left and right side portions of the lower layer mattress structure are connected to each other between a position that is a predetermined distance away from the top of the head and a position that is a predetermined distance away from the toe, and is separated from the top of the head by a predetermined distance. The position of the lower leg is the top of the rotation axis of the base end of the back bottom, and the position away from the foot tip by a predetermined distance is the lower leg that is pivotally connected to the tip of the thigh bottom that can be tilted It was decided to be on the side opposite to the foot than the base end of the bottom .

Moreover, in this invention which concerns on Claim 4, in this invention which concerns on any one of the said Claims 1-3, in connecting the said upper layer side mattress structure and a lower layer side mattress structure so that isolation | separation is possible. did.

  And in this invention, there exists an effect described below.

  That is, in the present invention, in the mattress used in the reclining bed in which the back bottom can be turned upside down, the upper layer side mattress constituent body and the lower layer side mattress constituent body are laminated in the upper and lower layers, and the left and right sides of the upper layer side mattress constituent body And the left and right sides of the lower mattress structure are connected between a position separated from the top by a predetermined distance and a position separated from the toe by a predetermined distance, so that the upper and lower layers are Displacement of the mattress structure can suppress the occurrence of distortion, and the upper and lower layer mattress structure can be restored to its original position when the back bottom is lying down. The feeling of use of the reclining bed can be improved without being pressed.

  Hereinafter, a specific configuration of the mattress according to the present invention will be described with reference to the drawings.

As shown in FIGS. 1 and 2, the mattress 1 according to the present invention is used by being placed on an upper part of a reclining bed 2.
First, the structure of the reclining bed 2 will be described. The reclining bed 2 includes a base 3 for installation on the floor and a cradle 4 for supporting the body of a lying person.

  The base 3 has legs 6 and 7 attached to the lower front and rear ends (lower left and right ends in FIGS. 1 and 2) of the rectangular frame-shaped main frame 5 and a rectangular plate-shaped headboard at the front end of the main frame 5. 8, a rectangular plate-like footboard 9 is attached to the rear end of the main frame 5.

  The cradle 4 is attached to a middle part of the front side of the main frame 5 with a base end portion of a back bottom 10 for supporting a back portion of a person lying in a supine position rotatably via a rotation shaft 11. A bottom bottom 12 for supporting the butt of a person lying down is fixed to the front side of the center of the frame 5, and the upper leg of the person lying down is supported to the rear side of the center of the main frame 5. The base end of the upper thigh bottom 13 is pivotally attached, and the base end of the lower thigh bottom 14 is supported to support the lower leg of a person lying on the tip of the upper thigh bottom 13 Installed on.

  A driving mechanism (not shown) is connected to the back bottom 10, and an interlocking mechanism (not shown) is connected between the back bottom 10 and the upper thigh bottom 13. The upper leg bottom 13 and the lower leg bottom 14 are tilted in conjunction with the tilting of the back bottom 10.

  Next, the structure of the mattress 1 will be described. As shown in FIGS. 3 and 4, the mattress 1 includes a rectangular plate-shaped upper mattress structure 16 inside a rectangular bag-shaped outer cover 15 having elasticity. The lower layer side mattress constituting body 17 is accommodated in a state of being laminated in a layered manner in the vertical direction. The upper layer side mattress constituting body 16 and the lower layer side mattress constituting body 17 are connected to each other by a connecting body 18 at the left and right side portions.

  The upper layer side mattress constituting body 16 is accommodated in a state in which a rectangular plate-like upper layer side upper mat 20 and an upper layer side lower mat 21 are layered vertically in a rectangular bag-shaped upper layer side inner cover 19 having elasticity. doing.

  Here, the upper-layer-side upper mat 20 is made of urethane that has excellent breathability and detergency that has been subjected to profile processing that provides a body-pressure dispersion effect, and the upper-layer-side lower mat 21 Uses polyethylene that has excellent breathability and cleanability, and extends in the width direction at the bent part (base end of the back bottom 10, base end of the upper thigh bottom 13, base end of the lower thigh bottom 14) The concave slit 22 is formed to improve the flexibility.

  The lower-layer side mattress constituting body 17 accommodates a rectangular plate-like lower-layer side mat 24 inside a rectangular bag-like lower-layer side inner cover 23 having elasticity.

  Here, the lower mat 24 is made of hard cotton having excellent durability and cleanability, and a concave slit 25 extending in the left-right width direction is formed at a predetermined interval to improve flexibility. I am letting. It should be noted that the distortion generated in the upper mattress structure 16 that directly presses the back of a person lying down so that the residual distortion during compression of the upper and lower upper and lower mats 20, 21 is smaller than that of the lower mat 24. Is made smaller than the lower layer mattress constituting body 17.

  The connecting body 18 attaches the upper side of the strip-shaped connecting piece 26 extending back and forth to the left and right sides of the upper layer side inner cover 19 of the upper layer side mattress constituting body 16, while the lower layer side inner cover 23 of the lower layer side mattress constituting body 17 The lower side of the strip-shaped connecting piece 27 extending in the front-rear direction is attached to the left right side, and the lower side of the connecting piece 26 and the upper side of the connecting piece 27 are connected to each other with a fastener 28 so as to be separable.

  As shown in FIG. 3, the connecting body 18 has a predetermined distance (L1) from the top of the head and a predetermined distance from the top of the foot when the mattress 1 is placed on the cradle 4 of the reclining bed 2. The left and right side portions of the upper layer side mattress constituting body 16 and the left and right side portions of the lower layer side mattress constituting body 17 are connected to a position separated by a distance (L2).

  In particular, here, the predetermined distance (L1) from the top of the head is shorter than the length of the back bottom 10 (distance from the tip to the base) (L3), and is separated from the top by a predetermined distance (L1). The position is such that it is closer to the top than the base end of the back bottom 10.

  In addition, the predetermined distance (L2) from the foot toe is longer than the length of the lower leg 14 (distance from the distal end to the proximal end) (L4), and is separated from the toe by a predetermined distance (L2). The position is such that it is on the side opposite to the foot side than the base end portion of the lower leg bottom 14 (on the opposite side of the foot tip side and between the base end portion and the distal end portion of the upper leg bottom 13).

  The mattress 1 is configured as described above. As shown in FIG. 5A, when the back bottom 10 of the reclining bed 2 is erected, the mattress 1 bends at the base end portion of the back bottom 10. At that time, the upper layer mattress constituting body 16 is displaced from the lower layer side mattress constituting body 17. Therefore, generation | occurrence | production of distortion is suppressed in the bending part of the mattress 1.

  Thereafter, as shown in FIG. 5B, when the back bottom 10 of the reclining bed 2 is laid down, the upper layer mattress constituting body 16 and the lower layer side mattress constituting body 17 are connected by the connecting body 18, A force that the upper layer side mattress constituting body 16 shifts in the opposite direction acts on the lower layer side mattress constituting body 17 to restore the displacement of the upper and lower layer side mattress constituting bodies 16 and 17 to the original state.

  Similarly, when the upper thigh bottom 13 and the lower thigh bottom 14 are tilted, a shift occurs at the time of standing to suppress the occurrence of distortion at the bent portion, and the shift is restored at the time of lying down.

  At that time, the mattress 1 is folded in a valley shape inside the base end (rotation center) of the back bottom 10 at the portion where the back bottom 10 is tilted, so that the base end of the back bottom 10 If the upper and lower mattress constituents 16 and 17 are not connected to the top of the head by the connecting body 18, the mattress 1 is bent inward and presses the back of the person lying on the side. Therefore, the position away from the top of the head by a predetermined distance (L1) is set to the top of the head from the base end of the back bottom 10.

  On the other hand, in the part where the lower leg bottom 14 is tilted with respect to the upper leg bottom 13, the mattress 1 is bent in a mountain fold shape outside the base end portion (rotation center) of the lower leg bottom 14, so that the lower leg bottom 14 If the upper and lower mattress components 16 and 17 are connected by the connecting body 18 from the base end portion to the toe side, the mattress 1 cannot be bent smoothly along the upper thigh bottom 13 and the lower thigh bottom 14. It will be in a state of being stretched. Therefore, the position away from the foot tip by a predetermined distance (L2) is set on the side opposite to the foot with respect to the base end of the crus bottom 14.

  As described above, the mattress 1 includes the upper-layer mattress constituent body 16 and the lower-layer mattress constituent body 17 stacked in layers in the vertical direction, and the left-right side portion of the upper-layer mattress constituent body 16 and the lower-layer mattress structure. The left and right sides of the body 17 are connected to each other between a position separated from the crown by a predetermined distance (L1) and a position separated from the foot tip by a predetermined distance (L2).

  Therefore, in the mattress 1 configured as described above, the upper and lower layer side mattress constituting bodies 16 and 17 can be prevented from being displaced when the back bottom 10 is erected, and the upper and lower layer side mattress structure can be suppressed when the back bottom 10 is lying down. The displacement of the bodies 16 and 17 can be restored to the original state, whereby the feeling of use of the reclining bed 2 (mattress 1) can be improved without squeezing the back of a lying person.

  Further, the mattress 1 has a configuration in which the upper layer side mattress constituent body 16 and the lower layer side mattress constituent body 17 are detachably connected.

  Therefore, in the mattress 1 having the above-described configuration, the upper and lower layer side mattress constituting bodies 16 and 17 can be separated and maintenance such as replacement and cleaning can be easily performed.

  Further, the mattress 1 has a position away from the top of the head by a predetermined distance (L1) from the base end of the back bottom 10 to the top of the head.

  Therefore, in the mattress 1 having the above-described configuration, it is possible to reliably prevent the occurrence of distortion on the top side of the base end portion of the back bottom 10.

  Furthermore, the mattress 1 is more anti-toe than the base end portion of the lower leg bottom 14 that is pivotally connected to the distal end portion of the upper leg bottom 13 that can be raised and lowered at a predetermined distance (L2) from the toe portion. The department side.

  Therefore, in the mattress 1, even in the reclining bed 2 in which the upper and lower thigh bottoms 13 and 14 can be tilted, it is possible to reliably prevent the occurrence of distortion on the toe side with respect to the base end portion of the lower thigh bottom 14. .
