Description

 Movable floor bed

 Technical field

 [0001] The present invention relates to a movable floor-type bed for nursing care mainly for people in need of care, such as physically handicapped people and elderly people with weak illness.

 Background art

 Generally, disabled people, sick elderly people, hospitalized patients after surgery, etc. are forced to live in the floor, but because the physical function declines when bedriding time is prolonged, muscle strength is increased. Gait training is considered to be extremely effective in relieving decline and stimulating the cerebrum.

 [0003] However, a person having a major functional impairment can not get up by himself !, and also needs care by his / her family or professional carer when eating, excreting, bathing, and the like.

 [0004] In particular, when raising the back on the bed to eat or walking away from the bed, although the upper comforter may be in the way, it is possible for the care recipient who is weak to be able to bounce off the upper comforter by himself. You can not do it, and even if you ask your carer to do this, you may have trouble keeping the upper comforter.

 Therefore, a stabilizer installed on the floor below the bed, a vertically movable main pillar vertically installed on the stabilizer, and an upper portion of the head connected to the upper portion of the main pillar open and close operation An automatic comforter device has been proposed which has an opening and closing dome capable of being used, and a covering frame is held by a lattice frame which constitutes the opening and closing dome (for example, a patent) Literature 1).

 Also, a hanging sheet covering unit provided with a pair of left and right telescopic poles is provided at the rear (foot side) of the bed frame, and the cloth body is stretched onto the bed frame by the extension of the telescopic poles. A bed has been proposed in which the cloth body is folded and stored at the side of the hanging sheet covering unit when the telescopic pole is contracted (for example, Patent Document 2).

 Patent Document 1: Japanese Patent Application Laid-Open No. 2002-177342

Patent Document 2: Japanese Patent Application Laid-Open No. 2004-290348 Disclosure of the invention

 Problem that invention tries to solve

 However, according to Patent Document 1, a dedicated drive source (power source) is provided to perform the vertical movement of the main pillar and the opening and closing motion of the open / close dome, and the drive sources operate based on the switch input and sensor input. Because it is controlled, there is a problem as the cost of equipment increases.

 In addition, since the entire apparatus is installed on one side of the bed, it is difficult to provide care, and the backrest portion (upper body rest portion) supporting the upper body of the recumbent is on the one side of the bed on which the ups and downs are operated. There is a risk that the back and forth dome will be destroyed if the backrest of the bed is erroneously erected while the back and forth dome is closed when the door is installed. There is a risk of getting into dyspnea by being caught between the backrest area.

 Furthermore, since the upper comforter is attached to the lower part of the open / close dome by Velcro (registered trademark), attachment to the open / close dome is difficult with thick heavy upper comforters.

 [0011] On the other hand, in Patent Document 2, since both sides of the upper quilt (cloth body) are supported by a telescopic pole in a cantilever state, the telescopic pole is used in the bed unless it is a very lightweight upper quilt. It can not be extended or contracted along the length direction, and a hanging sheet covering unit including its telescopic pole can be installed only on the left and right sides of the bed because it is installed on the foot side of the layman. In the case of a bed that changes to a chair-like shape, there is a problem that the seat covering unit becomes an obstacle in the case of walking training with the sitting posture uplifting force.

 The present invention has been made in view of the above circumstances, and its object is to provide a structure in which a portion supporting the upper body of a recumbent person moves up and down, and to eat or walk on a bed.

 BEST MODE FOR CARRYING OUT THE INVENTION

 Hereinafter, the present invention will be described in detail based on the drawings. FIG. 1 is a schematic side view showing a configuration example of a movable floor type bed according to the present invention. In FIG. 1, reference numeral 1 denotes a base frame configured to include a pair of left and right side plates 11, and on the upper portion thereof, a floor plate frame 2 supported horizontally by the base frame 1 is provided. The floorboard frame 2 is for supporting a layman, on which the flexible mattresses Dl, D2, D3 (the two mattresses Dl, D2 are an integral connected structure, such as a three-divided mattress). Good) are laid, and those duvets D1 to D3 are fixed to the floor board frame 2 with a belt or the like.

In particular, the floor board frame 2 is connected to the central rest 21 for supporting the buttocks of the layman, and an upper body rest for supporting the upper body (head and back) of the layperson connected to one end of the central rest 21. 22 and a lower leg rest 23 supporting the lower leg of the layman in a row on the other end side of the central rest 21 and having flexibility via the duvets D1 to D3 on the floor board frame 2 The sliding cover U is hung. Incidentally, one end of the upper body rest 22 (one end on the central rest 21 side) is the fulcrum shaft P1 on the bracket 12 formed in the upper edge center of the side plate 11 of the base frame. The first gear (gear 3) is fixed to its fulcrum shaft PI.

Then, according to the floor board frame 2 concerned, when the upper body rest 22 is converted into the laid posture and the upright posture, and when the upper body rest 22 is converted into the upright posture, the lower thigh rest 23 is the central rest. By being separated from one end portion of 21 and housed in the base frame 1, the whole changes into a chair-like shape, but such a mechanism will be described later.

On the other hand, in the upper part of the base frame 1, when the upper body rest 22 is converted to the laid posture, the floor plate frame 2 (accurately when the upper body rest 22 is interlocked with the ups and downs of the upper body rest 22). There is provided an overhead removal means 4 for lifting the upper comforter U hung on the floorboard 2 to a predetermined position above the floor 2. In FIG. 1, an imaginary line shows a state in which the upper covering member U is lifted by the upper cover removing means 4.

In the present embodiment, the overhead covering removal means 4 is provided on the left and right sides of the base frame 1 and turns upward when the upper body rest portion 22 is converted to the lying posture and the standing posture. It has a plurality of pivoting arms 41, 42 standing on the left and right sides, and a canopy frame 43 which forms a rectangular framework for holding the upper cover U connected to the free end sides of the respective pivoting arms 41, 42. Ru.

 The swing arms 41 and 42 are provided two on each of the left and right sides of the base frame 1 so as to be pivotable in the vertical direction, and a pair of left and right swing arms 41 and 41 provided in the center between the two. The second gear is engaged with the above gear 3 on the fulcrum shaft P2 of which one end is knotted by the pivot shaft P2 (pivotal fulcrum) for turning on the bracket 12 of the base frame 1 as the driving shaft. ) Is fixed.

 Also, a pair of left and right swing arms 42, 42 provided on both front sides (head side of a layman) of the base frame 1 have follower nodes that turn in accordance with the swing arms 41, 41 on the driving side. Each end is knotted with a bracket 13 formed on the upper edge front of the side plate 11 of the base frame at a fulcrum shaft P3.

On the other hand, as is apparent from FIGS. 1 and 2, the canopy frame 43 has a pair of left and right side links 43A, 43A connecting the free ends of the pivot arms 41, 41 and a pair of pivot arms 41, 41 and a second horizontal link shaft 43B, and a second horizontal link shaft 43B parallel to the first horizontal link shaft 43B and between one end of the side link 43A (the pair of left and right swing arms 42) Horizontal shaft 43C Is made.

 In particular, one end (the side covering the foot of the layman) of the upper comforter U is locked by a string or a belt to the first horizontal shaft 43B, and the second horizontal shaft 43C is shown in FIG. As shown by the dotted line, the middle portion of the upper cover U (the folded portion of the upper cover U folded up in half by folding up the head side, that is, the side covering the chest of the layman) is wound.

 [0031] And, according to the top covering removal means 4 concerned, when the upper body rest portion 22 of the floor board frame 2 is in the lying posture, the pivoting arms 41, 42 also lie in the laid posture along the side edges of the floor board frame 2. Although it maintains, when the upper body rest part 22 changes to a standing posture, the driving force is transmitted to the pivoting arms 41, 41 via the gears 3, 5 to allow the pivoting arms 41, 42 to be the fulcrum shaft P2. , P3 pivot upward in the direction opposite to the upper body rest 22 and stand on the left and right sides of the base frame 1, thereby pivoting the upper comforter U folded in half on the canopy frame 43. Arm 41 , 42 can be carried on floorboard frame 2 by the equivalent of length.

 Incidentally, in FIG. 1, it is preferable that forces having different lengths of the swing arms 41 and 42 have the same length so that the canopy frame 43 can be expanded horizontally. However, the combined length of the pivot arm 42 and the side link 43 A is set longer than the distance from the fulcrum shaft P3 of the pivot arm 42 to the free end of the pivot arm 41 and pivots when the pivot arms 41 and 42 fall. The nodal point of the arm 42 and the cyclic 43A bends upward (see the turning arm 42 and the side link 43A shown by the solid line in FIG. 1), whereby the turning arm 42 and the side link 43A are reversely directed. The canopy frame 43 is deployed above the floor plate frame 2 when the pivoting arms 41 and 42 are pivoted upward.

 [0033] Here, the second horizontal shaft 43C is provided with a non-slip member that also has a plurality of projecting forces of a plurality of rubber members or the first horizontal bridge so that the upper quilt U carried up by the top covering removal means 4 does not hang down. Preferably, a third horizontal shaft (not shown) is provided between the shaft 43B and the second horizontal shaft 43C. However, the second horizontal shaft 43C and the above-mentioned third horizontal shaft are pivot arms 41, As it does not touch the recumbrate at the time of 42 lodgings, especially if the recumbent hits the knees, both ends are bent downward to form a portal (back concave including arched) so that it has a height. Character).

Next, the structure of the floor board frame and the operation mechanism thereof will be described with reference to FIG. 3. The center rest 21 has one end on the upper body rest 22 side of the bracket 12 of the base frame 1 as a fulcrum It is knotted at the axis P4, and the lower thigh rest 23 side turns up and down around the fulcrum axis P4. Incidentally, a triangular cam body 6 projecting into the base frame 1 is provided at the bottom of the central rest 21 and the operation will be described later.

 On the other hand, in the upper body rest portion 22, one end on the central rest portion 21 side is knotted with the fulcrum shaft P1 to the bracket 12 of the base frame 1 as described above, and the fulcrum shaft P1 is used as a center It turns up and down. In particular, as apparent from FIG. 3, the pivot point (fulcrum shaft P1) of the upper body rest 22 is set at a position higher than the pivot point (fulcrum shaft P4) of the central rest 21. According to this, when the upper body rest portion 22 turns around the fulcrum axis P1 and changes from the laid posture to the upright posture, the duvet D2 on the upper body rest portion 22 and the duvet D1 on the central rest portion 21 bend. Since it is prevented from being raised on the side of the layman at the boundary between the two under pressure, the layman does not feel uncomfortable as if the waist is compressed, and the force also acts on the boundary between the duvets D1 and D2. Since the bending pressure is reduced, the uprest operation of the upper body rest 22 can be smoothly performed under low load.

 Reference numeral 7 denotes a drive mechanism for converting the upper body rest portion 22 to a falling posture posture and a standing posture, which is rotationally driven by a driving source 71 (reversible motor) attached to the base frame 1 and the driving source. The screw shaft 72 and the rotational movement of the screw shaft 72 also constitute a force such as a slider 73 moving in the axial direction. Among them, the screw shaft 72 is provided along the longitudinal direction of the base frame 1 and both ends thereof are rotatably supported by a bearing unit 74 fixed to the side plate 11 of the base frame 1.

 Further, the slider 73 is formed by integrally putting together a nut portion 73A screwed to the screw shaft 72 and a slide plate 73B in sliding contact with the side plate 11 of the base frame 1, and the slide plate 73B vertically A long hole 73C extending in the direction is drilled.

 The screw shafts 72 and the sliders 73 are provided opposite to the left and right sides (only one side is shown in FIG. 3) of the base frame 1, and the left and right slide plates 73, 73 have long holes. Cross shaft 75 is stretched at position 73C. And, a cross arm shaft 75 and a bracket 22 A fixed to the upper body rest portion 22 are connected by a connecting arm 76.

Thus, when the slider 73 moves to the right in FIG. 3 by the rotational drive of the screw shaft 72, the connecting arm 76 gradually rises and the downward force on the upper body rest 22 in the lying posture also pushes up. In order to act in a collapsing manner, the upper body rest portion 22 pivots upward about the fulcrum shaft P1 and the lying posture force is also converted to the standing posture, and the overhead removing means 4 shown in FIG. 1 interlocks with this.

Further, according to the movable floor type bed according to the present invention, when the upper body rest portion 22 is converted to the laid posture, the lower leg rest portion 23 side in the base frame 1 is interlocked with this. The movable frame 8 is provided to move the force to the upper body rest 22 side.

The movable frame 8 is connected to the slider 73 via the horizontal support shaft 75, and when the slider 73 moves to the right in FIG. 3, the movable frame 8 moves in the same direction along the slider 73. It has become.

 In particular, a lower leg rest 23 unconnected to the central rest 21 is fixed on the upper surface of the movable frame 8 as a body, and the left and right side plates 11 of the base frame 1 are movable frames A pair of guide rails 14 and 15 for guiding the movement of six is provided on the left and right sides. In the present embodiment, the guide rails 14 and 15 are slits formed by cutting through the side plate 11 of the base frame, and the end of the horizontal shaft 75 passes through the movable frame 8 and one guide rail 14. A guide roller 81 provided in the movable frame 8 is fitted in the other guide rail 15 which is inserted in the long hole 73 C of the slider. As shown in FIG. 4, a guide roller 82 fitted to the guide rail 14 and the long hole 73C of the slide plate is also provided at the end of the horizontal shaft 75.

 Thus, when the slider 73 for raising the upper body rest 22 is moved to the right in FIG. 3, the movable frame 8 is also along the guide rails 14 and 15 from the lower thigh rest 23 side from the upper body rest 2 Move to 2 side.

 When the movable frame 8 starts moving toward the upper body rest 22, the movable frame 8 is converted to the inclined posture while being lowered by the end shape of the guide rails 14 and 15. There is. For this reason, the lower leg rest 23 fixed on the upper surface of the movable frame 8 releases the force at one end of the central rest 21 so that the inside of the base frame 1 is integrated with the movable frame 8 on the upper body rest 22 side. You can move to

The movable frame 8 is provided with a press roller 83 as a contact that engages with the cam body 6, and the movable frame 8 moves toward the upper body rest 22 also with the lower leg rest 23 side force. In the initial stage, one of the V-shaped end faces of which the pressure roller 83 forms the cam profile of the cam body 6 By pressing 6A, the central rest 21 provided with the cam body 6 at the bottom is pivoted upward about the fulcrum shaft P4.

According to this, in order that the upper thighs of the liever M are pushed up as shown in FIG. 5, the buttocks of the layover M slide toward the lower thigh rest 23 by the standing motion of the upper body rest 22. It is possible to prevent In the stage where the movable frame 8 moves to the middle point (the stage when the inclination angle of the upper body rest 22 reaches 30 to 50 degrees), the contact of the pressure roller 83 switches the one 6A force of the V-shaped end face to the other 6B. Thus, the pivoting of the central rest 21 is turned downward.

 As is clear from FIGS. 3 and 5, a rolling roller 23A is provided at the end of the lower leg rest 23 over the entire width thereof, and the movable frame 8 and the lower leg rest 23 are at the top. When moving to the body rest 22 side, the lower thighs of the recumbent are supported by the rolling rollers 23A, so that the lower legs are smoothly lowered until the feet land.

 Next, FIG. 6 shows a state in which the upper body rest 22 is turned to the standing posture. As is apparent from this figure, according to the bed of the present invention, when the upper body rest 22 is turned to the standing posture, the lower leg rest 23 is accommodated in the base frame 1 at the lower position of the central rest 21. The bed is in the form of a chair with the central rest 21 as a seating surface, and in this state the recumbent (in this stage, the recumbent M becomes a seated person) folds the lower leg (leg) into an acute angle to form a central rest. It is permitted to land the foot in the lower position of the section 21, which allows the seat occupant to move the center of gravity of the body forward and stand up without assistance from the caregiver.

 In the chair-shaped state shown in FIG. 6, it is possible to eat, and if the central rest 21 is fitted with a toilet bowl, it is also possible to perform defecation. Further, as is apparent from FIG. 6, when the upper body rest 22 is in the upright posture, the canopy frame 43 is above the upper body rest 22 in the upright posture and is held by the canopy frame 43. The upper comforter does not interfere with the occupant's head.

On the other hand, when the drive source 41 is driven in the reverse direction in the state of FIG. 6, the movable frame 8 is returned to the initial position while the upper body rest 22 is pivoted downward, and the central rest 21, The upper body rest portion 22 and the lower leg rest portion 23 are connected in a flat shape to return to the bed form as shown in FIG. Next, the specific structure of each member constituting the movable floor type bed as described above will be described. First, the structure of the base frame 1 will be described with reference to FIGS. 7 to 9. The base frame 1 is a box having a pair of left and right side plates 11 and 11, a bottom plate 16 and a front plate 17.
