Description

  TECHNICAL FIELD The present invention relates to a movable bed for care mainly intended for a care recipient such as a disabled person or a sickly elderly person, and an overhanging device for a bed.

  In general, people with disabilities, sick elderly people, hospitalized patients after surgery, etc. are forced to live on the floor, but as bedridden time increases, physical function declines, so the decline in muscle strength is recovered. Walking training is considered to be extremely effective for stimulating the cerebrum.

  However, those who have a major functional disorder cannot get up on their own, and they need to be cared for by their relatives and specialized caregivers during meals, excretion and bathing.

  In particular, when you wake up on the bed and eat or walk away from the bed, the upper comforter may be in the way, but the incapacitated caregiver cannot jump off the upper comforter, Even if this is done by a caregiver, it may be difficult to place the upper comforter.

  Therefore, a stabilizer installed on the floor under the bed, a main pillar vertically installed on the stabilizer, and an upward / downward movement of the main pillar connected to the upper part of the main pillar. There has been proposed an automatic comforter device that has an openable / closable dome and an upper comforter that is held by a lattice frame-like frame that constitutes the openable / closable dome (for example, Patent Document 1).

  In addition, a hanging sheet covering unit having a pair of left and right telescopic poles is provided at the rear part (foot side) of the bed frame body, and the cloth body extends on the bed frame body due to the extension of the telescopic pole, and the telescopic pole A bed has been proposed in which the cloth body is folded and stored on the hanging sheet covering unit side when the size is reduced (for example, Patent Document 2).

Furthermore, a device has been proposed in which a support is provided on one side of the base, and one end edge of a holding frame forming a lattice shape is rotatably attached to the upper part of the support so that the holding frame on which the upper comforter is hung can be flipped up. (For example, Patent Document 3)
JP 2002-177342 A JP 2004-290348 A JP-A-10-57427

  However, according to Patent Document 1, a dedicated drive source (power source) is provided to perform the vertical motion of the main pillar and the open / close operation of the open / close dome, and the drive source is controlled to operate based on the switch input or the sensor input. Therefore, there is a problem that the device cost becomes high.

  In addition, since the entire apparatus is installed on one side of the bed, it is difficult to provide care, and when the apparatus is installed on one side of the bed where the backrest part (upper body rest part) that supports the upper body of the lying person performs the undulation action, If the backrest part of the bed is accidentally raised while the open / close dome is closed, there is a risk that the open / close dome will be destroyed, and the lying person will be between the open / close dome and the backrest part of the bed. There is a risk of falling into breathing difficulty.

  Further, since the upper comforter is attached to the lower part of the opening / closing dome by Velcro (registered trademark), it is difficult to attach the upper comforter to the opening / closing dome with a thick heavy upper comforter.

  On the other hand, in Patent Document 2, since both sides of the upper comforter (cloth body) are supported by the cantilevered telescopic poles, the telescopic poles are arranged in the length direction of the bed unless they are extremely lightweight. It cannot be extended and retracted, and the hanging seat covering unit that includes the telescopic pole is installed on the foot side of the lying person, so it can only enter and exit from both the left and right sides of the bed, changing to a chair shape There is a problem that the seat covering unit becomes an obstacle when walking up from a sitting posture in a bed.

  Further, in Patent Document 3, since the support column always stands on the side of the lying person, it is difficult to care for the lying person, and the holding frame is supported in a cantilevered state. It is difficult to use, and when the holding frame is flipped up, there is a high possibility that the upper comforter will slide down.

  Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 1 is a schematic side view showing a configuration example of a movable floor bed according to the present invention. In FIG. 1, reference numeral 1 denotes a base frame that includes a pair of left and right side plates 11, and a floor plate frame 2 that is supported horizontally by the base frame 1 is provided on the top frame. The floorboard frame 2 is for supporting a lying person, and on the top, there is a flexible mattress D1, D2, D3 such as a mattress divided into three (the two mattresses D1, D2 may be an integrally connected structure) ) And the mattresses D1 to D3 are fixed to the floor board frame 2 with a belt or the like.

  In particular, the floorboard frame 2 includes a central rest portion 21 that supports the recumbent's buttocks, an upper body rest portion 22 that supports the upper body (head and back) of the recumbent, connected to one end of the central rest portion 21; The upper quilt U is composed of a crus rest part 23 that is connected to the other end of the central rest part 21 and supports the lower leg part of the lying person, and has flexibility on the floorboard frame 2 via mattresses D1 to D3. Is multiplied. One end of the upper body rest portion 22 (one end on the side of the central rest portion 21) is knotted by a fulcrum shaft P1 to a bracket 12 formed at the center of the upper edge of the side plate 11 of the base frame. The gear 3 is fixed to P1.

  According to the floorboard frame 2, the upper body rest portion 22 is converted into the lying posture and the standing posture, and when the upper body rest portion 22 is changed into the standing posture, the lower leg rest portion 23 is one end of the central rest portion 21. The entire structure is changed into a chair shape by being separated from the portion and accommodated in the base frame 1, and the mechanism will be described later.

  On the other hand, on the upper part of the base frame 1, when the upper body rest portion 22 changes from the lying posture to the standing posture in conjunction with the raising and lowering movement of the upper body rest portion 22, the floor frame 2 (exactly the floor plate frame) 2 is provided for lifting the upper comforter U, which is hung on the floor 2) to a predetermined height position on the floor board frame 2. In FIG. 1, a state in which the upper comforter U is lifted up by the upper hook removing means 4 is indicated by an imaginary line.

  In this example, the overhanging means 4 is provided on the left and right sides of the base frame 1 and is in a plane parallel to the length direction of the base frame 1 when the upper body rest portion 22 changes from the lying posture to the standing posture. And a plurality of swivel arms 41 and 42 that rise upward on both the left and right sides of the base frame 1 and a rectangular frame that is connected to the free end side of each of the swivel arms 41 and 42 to hold the upper comforter U. It is comprised with the canopy frame 43 to form.

  Two turning arms 41, 42 are provided on each of the left and right sides of the base frame 1 so as to be turnable in the vertical direction. Of these, the pair of left and right turning arms 41, 41 provided at the center of both sides serve as a driving node. Each end thereof is connected to a bracket 12 of the base frame 1 by a fulcrum shaft P2 for turning, and a gear 5 that meshes with the gear 3 is fixed to the fulcrum shaft P2.

  Also, the pair of left and right turning arms 42 and 42 provided at the front portions on both sides (the side of the lying person) of the base frame 1 is a follower that turns following the turning arms 41 and 41 on the driving side. Each end is configured to be knotted by a fulcrum shaft P3 to a bracket 13 formed at the upper edge front portion of the side plate 11 of the base frame.

  On the other hand, as can be seen in FIGS. 1 and 2, the canopy frame 43 is formed between the pair of left and right side links 43 </ b> A and 43 </ b> A connecting the free ends of the swing arms 41 and 42 and the pair of left and right swing arms 41 and 41. The first horizontal shaft 43B installed between the first horizontal shaft 43B and the second horizontal shaft 43C installed between one end of the side link 43A (on the pair of left and right turning arms 42) in parallel with the first horizontal shaft 43B. It consists of.

  In particular, one end on the foot side of the upper comforter U (the side covering the feet of the lying person) is locked to the first horizontal shaft 43B by a string or a belt, and the second horizontal shaft 43C is indicated by a dotted line in FIG. As shown in the figure, an intermediate part of the upper comforter U (the folded part of the upper comforter U that is folded up by folding the head side, that is, the side covering the chest of the lying person) is wound.

  Then, according to the overhanging exclusion means 4, when the upper body rest portion 22 of the floorboard frame 2 is in the lying posture, the swing arms 41 and 42 also maintain the lying posture along both side edges of the floorboard frame 2. When the upper body rest portion 22 changes to the standing posture, the driving force is transmitted to the swing arms 41 and 41 via the gears 3 and 5, so that the swing arms 41 and 42 are centered on the fulcrum axes P2 and P3. The upper comforter U is turned upward in the opposite direction to the upper body rest portion 22 and rises to the left and right sides of the base frame 1, whereby the upper comforter U held in a folded state on the canopy frame 43 is equivalent to the length of the turning arms 41 and 42. Only can be carried on the floorboard frame 2.

  In FIG. 1, the lengths of the swivel arms 41 and 42 are different, but it is preferable that the lengths are the same because the canopy frame 43 can be deployed horizontally. However, the combined length of the swivel arm 42 and the side link 43A is set to be longer than the distance from the fulcrum axis P3 of the swivel arm 42 to the free end of the swivel arm 41. 42 and the side link 43A are bent upward (see the swivel arm 42 and the side link 43A shown by the solid lines in FIG. 1), whereby the swivel arm 42 and the side link 43A are turned in the opposite direction. The canopy frame 43 is developed above the floorboard frame 2 when the swivel arms 41 and 42 are swung upward by performing a swivel operation.

  Here, a slip stopper made of a rubber material or a plurality of protrusions is provided on the second horizontal shaft 43C so as not to hang down the upper comforter U lifted by the upper hook removing means 4, or the first horizontal shaft 43B Although it is preferable to provide a third horizontal shaft (not shown) between the second horizontal shaft 43C and the second horizontal shaft 43C and the third horizontal shaft, In order to avoid contact with the lying person at times, in particular, the both sides are bent downward so that the height of the lying person does not hit even when standing on the knee, and the gate shape (reverse concave shape including the arch shape) is formed. .

  Next, the configuration of the floorboard frame and its operation mechanism will be described with reference to FIG. 3. The central rest portion 21 is connected to the bracket 12 of the base frame 1 at one end on the upper body rest portion 22 side at the fulcrum shaft P4. Then, the lower leg rest portion 23 side turns in the vertical direction around the fulcrum axis P4. In addition, although the triangular cam body 6 which protrudes in the base frame 1 is provided in the bottom part of the center rest part 21, the effect | action is mentioned later.

  On the other hand, the upper body rest portion 22 has one end portion on the side of the central rest portion 21 connected to the bracket 12 of the base frame 1 at the fulcrum axis P1 as described above, and is vertically moved around the fulcrum axis P1. It is designed to turn. In particular, as is clear from FIG. 3, the turning fulcrum (fulcrum axis P1) of the upper body rest portion 22 is set at a position higher than the turning fulcrum (fulcrum axis P4) of the central rest portion 21. According to this, when the upper body rest portion 22 turns around the fulcrum axis P1 and changes from the lying posture to the standing posture, the mattress D2 on the upper body rest portion 22 and the mattress D1 on the central rest portion 21 are subjected to bending pressure. Is prevented from rising to the recumbent side at the boundary part between the two, so that the recumbent does not feel uncomfortable as the waist is compressed, and the bending pressure on the boundary part of the mattresses D1 and D2 is reduced. Therefore, the standing motion of the upper body rest portion 22 can be smoothly performed under a low load.

  Reference numeral 7 denotes a drive mechanism that changes the upper body rest portion 22 from a lying posture to a standing posture, which includes a drive source 71 (reversible motor) attached to the base frame 1 and a screw shaft 72 that is rotationally driven by the drive source. And a slider 73 that moves in the axial direction when the screw shaft 72 is rotationally driven. Among these, the screw shaft 72 is provided along the longitudinal direction of the base frame 1, and both ends thereof are rotatably supported by bearing units 74 fixed to the side plate 11 of the base frame 1.

  The slider 73 is formed by integrating a nut portion 73A that is screwed onto the screw shaft 72 and a slide plate 73B that is in sliding contact with the side plate 11 of the base frame 1. The slide plate 73B has a long hole that extends in the vertical direction. 73C is drilled.

  The screw shaft 72 and the slider 73 are provided opposite to the left and right sides of the base frame 1 (only one side is shown in FIG. 3), and the pair of left and right slide plates 73, 73 are at the position of the long hole 73C. A horizontal shaft 75 is stretched over. The horizontal shaft 75 and the bracket 22 </ b> 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 articulated arm 76 acts to push up the upper body rest portion 22 from below while gradually rising. The rest portion 22 turns upward about the fulcrum axis P1 to change from the lying posture to the standing posture, and the overhanging exclusion means 4 shown in FIG.

  In addition, according to the movable bed type bed according to the present invention, when the upper body rest portion 22 is changed from the lying posture to the standing posture, the upper body is moved in the base frame 1 from the lower leg rest portion 23 side in conjunction with this. A movable frame 8 that moves to the rest portion 22 side is provided.

  The movable frame 8 is connected to the slider 73 via the horizontal shaft 75, and when the slider 73 moves to the right in FIG. 3, the movable frame 8 accompanies the slider 73 and moves in the same direction. Yes.

  In particular, a lower leg rest portion 23 that is not connected to the central rest portion 21 is integrally fixed to the upper surface portion of the movable frame 8, and movement guides of the movable frame 6 are provided on the left and right side plates 11 of the base frame 1. A pair of two guide rails 14 and 15 are provided on the left and right. In this example, the guide rails 14 and 15 are slits formed 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 of the guide rails 14 to extend the length of the slider. A guide roller 81 provided in the movable frame 8 is fitted into the other guide rail 15 and inserted into the hole 73C. As shown in FIG. 4, a guide roller 82 that is fitted into the guide rail 14 and the long hole 73 </ b> C of the slide plate is also provided at the end of the horizontal shaft 75.

  Thus, when the slider 73 moves to the right in FIG. 3 to erect the upper body rest portion 22, the movable frame 8 also moves from the lower leg rest portion 23 side to the upper body rest portion 22 side along the guide rails 14 and 15. Moving.

  When the movable frame 8 starts moving toward the upper body rest portion 22 side, the movable frame 8 is converted into an inclined posture while being lowered by the shape of the end portions of the guide rails 14 and 15. For this reason, the crus rest part 23 fixed to the upper surface part of the movable frame 8 is detached from one end part of the central rest part 21, and the inside of the base frame 1 remains on the upper body rest part 22 side while being integrated with the movable frame 8. Can move.

  Further, the movable frame 8 is provided with a pressure roller 83 as a contact that engages with the cam body 6, and in an initial stage when the movable frame 8 moves from the lower leg rest portion 23 side to the upper body rest portion 22 side. When the pressure roller 83 presses one of the V-shaped end surfaces 6A forming the cam contour of the cam body 6, the central rest portion 21 having the cam body 6 at the bottom is turned upward about the fulcrum shaft P4.

  According to this, since the upper leg part of the lying person M is pushed up as shown in FIG. 5, the standing part of the upper body rest part 22 prevents the lying part of the lying person M from sliding to the lower leg rest part 23 side. can do. At the stage where the movable frame 8 moves to the intermediate point (the stage where the inclination angle of the upper body rest portion 22 reaches 30 to 50 degrees), the contact of the pressure roller 83 is switched from one 6A on the V-shaped end surface to the other 6B. Thus, the turning of the central rest portion 21 is changed downward.

  As apparent from FIGS. 3 and 5, a rolling roller 23A is provided at the end of the lower leg rest portion 23 over the entire width thereof, so that the movable frame 8 and the lower leg rest portion 23 are the upper body rest portion. The lower roller of the lying person is supported by the rolling roller 23A when moving to the 22 side, and the lower leg is smoothly lowered until the foot lands.

  Next, FIG. 6 shows a state in which the upper body rest portion 22 is changed to a standing posture. As is clear from this figure, according to the bed according to the present invention, when the upper body rest portion 22 changes to the standing posture, the lower leg rest portion 23 is accommodated in the base frame 1 at a position below the central rest portion 21. The bed has a chair shape with the central rest portion 21 as a seating surface. In this state, the recumbent (the recumbent M becomes the seated person at this stage) bends the lower limb (leg) into an acute angle, and the central rest portion Therefore, the seated person can stand up by himself / herself without the help of the caregiver by moving the center of gravity of the body forward.

  In addition, in the state of the chair shape shown in FIG. 6, it is also possible to eat, and it is possible to defecate if a toilet bowl is attached to the central rest portion 21. Further, as apparent from FIG. 6, when the upper body rest portion 22 is changed to the standing posture, the canopy frame 43 is above the upper body rest portion 22 in the standing posture and is held by the canopy frame 43. The upper comforter is designed not to interfere with the seated person's head.

  On the other hand, if 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 portion 22 is turned downward, and the central rest portion 21, the upper body rest portion 22 and the lower leg rest portion 23 are connected in a flat shape to return to the form of the bed as shown in FIG.

  Next, the specific structure of each member which comprises the above movable floor type beds is demonstrated. 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 shape having a pair of left and right side plates 11, 11, a bottom plate 16 and a front plate 17.

The main body portion of the driving source 109 is swingably supported by a bracket 103A fixed to the column 103, and the tip of the telescopic rod 109A extending from the main body portion is supported. Connected to the lever 106.

  On the other hand, a canopy frame 110 that forms a frame for holding the upper comforter is connected to the free ends of the swivel arms 104 and 105. The canopy frame 110 includes a pair of left and right side links 111 and 111 to which the free ends of the swivel arms 104 and 105 are connected, and a first horizontal shaft 112 installed between one end portions of the both side links 111 and 111. The second horizontal shaft 113 is provided between the other end portions of the side links 111 and 111 in parallel with the first horizontal shaft 112.

  In particular, one end of the upper comforter on the foot side (the side covering the feet of the lying person) is locked to the first horizontal shaft 112 by a string or belt, and the second horizontal shaft 113 is excluded when the upper comforter is excluded. One end of the upper comforter on the head side (the side covering the chest of the lying person) is wound around.

  The length of the first horizontal shaft 112 and the second horizontal shaft 113 can be adjusted according to the width of the bed in the same manner as the horizontal material 101 that connects the base materials 100 and 100. Further, as shown in FIG. 18, the second horizontal shaft 113 is bent downward at both ends so as to have a gate shape (a reverse concave shape including an arch shape), and the canopy frame 110 is lowered by the downward swing of the swing arms 104 and 105. Even when the second horizontal shaft 113 does not interfere with the lying person on the bed.

  FIG. 19 shows a state in which the top exclusion device configured as described above is provided in the bed B. As is clear from this figure, according to the above-described overhanging device, the pair of left and right base materials 100, 100 are connected by the horizontal member 101 passed under the bed B, and the whole is assembled. The swivel arms 104 and 105 are positioned on both the left and right sides. The swivel arms 104 and 105 swivel up and down in a plane parallel to the length direction of the bed B, and the canopy frame 110 connected to the free end side thereof is moved up and down while maintaining a horizontal state.

  Further, when the upper comforter U is removed as described above, the canopy frame 110 is moved up to a predetermined height position on the bed B with one end portion of the head B side wrapped around the second horizontal shaft 113. However, when the canopy frame 110 is lowered, the one end portion of the upper comforter U can be removed from the second horizontal shaft 113 and can be hung on the chest of the lying person.

  Here, as is apparent from FIG. 20, the bed B has a floorboard frame 200 in which an upper body rest part 201, a central rest part 202, a lower leg rest part 203, and a foot rest part 204 are connected in a freely bending manner. When the drive source 205 (cylinder device) is driven, the upper body rest portion 201 changes from the lying posture to the standing posture, while the lower leg rest portion 203 is bent downward and the foot rest portion 204 is folded on the back side. Thus, the entire structure is converted into a chair shape having the central rest portion 202 as a seat portion. However, the upper device according to the present invention is not limited to that type of bed B, and is attached to various beds. The upper comforter U can be eliminated while being held on the canopy frame 110 raised on the bed.

  Next, a description will be given of a modified example of the canopy frame. The canopy frame 120 shown in FIGS. 21 to 24 has a configuration in which a pair of left and right side links 121 and 121 are connected by a plurality of ribs 122A. It is set as the holding | maintenance part 122 which hold | maintains the upper comforter U in the state hung from the leg part of the lying person on the bed B (floor board frame 2,200). According to this, since the leg part of the lying person is not compressed by the upper comforter U, the sleeping comfort is good, and the heater can be arranged in the holding part 122 to heat the lying person's feet.

  In particular, each rib 122A has an arch-like shape that is curved upward so as not to interfere with the legs of the lying person on the bed, and a tunnel-like cavity that can accommodate the lying person's legs is formed inside the rib 122A. Is done. An upper comforter U is placed on the holding part 122 so as to cover the leg part of the lying person, and the head side of the upper comforter U projects from the holding part 122 to cover the breast part of the lying person. Further, a hanging curtain 123 is attached to a rib 122A located on the foot side of the lying person in the holding portion 122, and the opening part on the foot side of the lying person is closed by the hanging curtain 123.

  The canopy frame 120 is also connected to the free end side of the swivel arms 41, 42/104, 105 shown in FIGS. 1, 16, etc., and is raised and lowered on the bed, but the upper comforter U is excluded by the rise. In some cases, it can be placed on the holding portion 122 in a state of being folded into two of the upper comforters U as shown in FIG.

  Although the present invention has been described above, the holding portion 122 is not limited to being formed by the plurality of ribs 122A, and may be formed by a semicircular plate material that covers the entire leg portion of the lying person.

  The present invention relates to a bed top-riding device mainly intended for a care recipient such as a disabled person or a sickly elderly person.

  In general, people with disabilities, sick elderly people, hospitalized patients after surgery, etc. are forced to live on the floor, but as bedridden time increases, physical function declines, so the decline in muscle strength is recovered. Walking training is considered to be extremely effective for stimulating the cerebrum.

  However, those who have a major functional disorder cannot get up on their own, and they need to be cared for by their relatives and specialized caregivers during meals, excretion and bathing.

  In particular, when you wake up on the bed and eat or walk away from the bed, the upper comforter may be in the way, but the incapacitated caregiver cannot jump off the upper comforter, Even if this is done by a caregiver, it may be difficult to place the upper comforter.

  Therefore, a stabilizer installed on the floor under the bed, a main pillar vertically installed on the stabilizer, and an upward / downward movement of the main pillar connected to the upper part of the main pillar. There has been proposed an automatic comforter device that has an openable / closable dome and an upper comforter that is held by a lattice frame-like frame that constitutes the openable / closable dome (for example, Patent Document 1).

  In addition, a hanging sheet covering unit having a pair of left and right telescopic poles is provided at the rear part (foot side) of the bed frame body, and the cloth body extends on the bed frame body due to the extension of the telescopic pole, and the telescopic pole A bed has been proposed in which the cloth body is folded and stored on the hanging sheet covering unit side when the size is reduced (for example, Patent Document 2).

Furthermore, a device has been proposed in which a support is provided on one side of the base, and one end edge of a holding frame forming a lattice shape is rotatably attached to the upper part of the support so that the holding frame on which the upper comforter is hung can be flipped up. (For example, Patent Document 3)
JP 2002-177342 A JP 2004-290348 A JP-A-10-57427

  However, according to Patent Document 1, a dedicated drive source (power source) is provided to perform the vertical motion of the main pillar and the open / close operation of the open / close dome, and the drive source is controlled to operate based on the switch input or the sensor input. Therefore, there is a problem that the device cost becomes high.

  In addition, since the entire apparatus is installed on one side of the bed, it is difficult to provide care, and when the apparatus is installed on one side of the bed where the backrest part (upper body rest part) that supports the upper body of the lying person performs the undulation action, If the backrest part of the bed is accidentally raised while the open / close dome is closed, there is a risk that the open / close dome will be destroyed, and the lying person will be between the open / close dome and the backrest part of the bed. There is a risk of falling into breathing difficulty.

  Further, since the upper comforter is attached to the lower part of the opening / closing dome by Velcro (registered trademark), it is difficult to attach the upper comforter to the opening / closing dome with a thick heavy upper comforter.

  On the other hand, in Patent Document 2, since both sides of the upper comforter (cloth body) are supported by the cantilevered telescopic poles, the telescopic poles are arranged in the length direction of the bed unless they are extremely lightweight. It cannot be extended and retracted, and the hanging seat covering unit that includes the telescopic pole is installed on the foot side of the lying person, so it can only enter and exit from both the left and right sides of the bed, changing to a chair shape There is a problem that the seat covering unit becomes an obstacle when walking up from a sitting posture in a bed.

  Further, in Patent Document 3, since the support column always stands on the side of the lying person, it is difficult to care for the lying person, and the holding frame is supported in a cantilevered state. It is difficult to use, and when the holding frame is flipped up, there is a high possibility that the upper comforter will slide down.

  The present invention has been made in view of the circumstances as described above, and an object of the present invention is to provide an upper exclusion device that can be reliably excluded without being dropped on the floor even with a thick upper comforter attached to various beds. It is to provide.

In order to achieve the above object, the present invention
(1) An upper device that removes an upper comforter that is attached to a bed and hangs on the bed to a predetermined height position.
A plurality of swivel arms arranged on the left and right sides of the bed and capable of swiveling in a vertical direction within a plane parallel to the length direction of the bed, and the upper comforter connected to the free end side of each swivel arm And a canopy frame that forms a frame for holding the canopy, and the canopy frame is moved up and down while holding the upper comforter on the bed by a turning operation of the turning arm.
(2) In addition, the canopy frame includes a first horizontal shaft for locking one end on the foot side of the upper comforter, and an intermediate portion of the upper comforter or a head of the upper comforter in parallel with the first horizontal shaft. It has the 2nd horizontal shaft by which the one end part of a side is wound, It is characterized by the above-mentioned.
(3) The canopy frame has a holding portion that holds the upper comforter in a state of floating on the bed from the lying person's legs, and when the canopy frame is raised, the upper canopy frame is folded on the holding portion. It is the structure which can be mounted in piles.

  According to the overhanging device according to the present invention, the swivel arm can be swung up and down in a plane parallel to the length direction of the bed, so that the swivel arm lies on both the left and right sides of the bed. Since the swivel arm does not become an obstacle for nursing care, and the swivel arms are arranged on both the left and right sides of the bed, the canopy frame that forms the frame for holding the upper comforter is connected to the free end side of the swivel arm. The frame does not tilt to the left and right, so that the upper comforter can be removed while being held by the canopy frame. Further, in the state where the upper comforter is removed while being held by the canopy frame, an effect that the upper comforter can be dried is also obtained.

  The canopy frame has a first horizontal shaft for locking one end on the foot side of the upper comforter, and an intermediate portion of the upper comforter or one end portion on the head side of the upper comforter is wrapped around the first horizontal shaft. Since it has a second horizontal shaft, it can securely hold even a thick heavy upper comforter carried on the floorboard frame to prevent it from hanging down, and the top removal device is integrated with the bed frame. It is possible to care for the lying person from both sides of the bed in a state where it is not equipped with space and the upper comforter is not lifted up.

  In addition, in the canopy frame having a holding part that holds the upper comforter in a state of being floated from the legs of the lying person on the bed, even if a thick upper comforter is used, the legs of the lying person are not compressed, Both legs can be moved freely, and when the canopy frame is raised, the upper comforter can be folded over the holding portion to prevent the upper comforter from slipping down.

  Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 1 is a schematic side view showing a configuration example of a movable bed type bed provided with a bed top exclusion device according to the present invention. In FIG. 1, reference numeral 1 denotes a base frame that includes a pair of left and right side plates 11, and a floor plate frame 2 that is supported horizontally by the base frame 1 is provided on the top frame. The floorboard frame 2 is for supporting a lying person, and on the top, there is a flexible mattress D1, D2, D3 such as a mattress divided into three (the two mattresses D1, D2 may be an integrally connected structure) ) And the mattresses D1 to D3 are fixed to the floor board frame 2 with a belt or the like.

  In particular, the floorboard frame 2 includes a central rest portion 21 that supports the recumbent's buttocks, an upper body rest portion 22 that supports the upper body (head and back) of the recumbent, connected to one end of the central rest portion 21; The upper quilt U is composed of a crus rest part 23 that is connected to the other end of the central rest part 21 and supports the lower leg part of the lying person, and has flexibility on the floorboard frame 2 via mattresses D1 to D3. Is multiplied. One end of the upper body rest portion 22 (one end on the side of the central rest portion 21) is knotted by a fulcrum shaft P1 to a bracket 12 formed at the center of the upper edge of the side plate 11 of the base frame. The gear 3 is fixed to P1.

  According to the floorboard frame 2, the upper body rest portion 22 is converted into the lying posture and the standing posture, and when the upper body rest portion 22 is changed into the standing posture, the lower leg rest portion 23 is one end of the central rest portion 21. The entire structure is changed into a chair shape by being separated from the portion and accommodated in the base frame 1, and the mechanism will be described later.

  On the other hand, on the upper part of the base frame 1, when the upper body rest portion 22 changes from the lying posture to the standing posture in conjunction with the raising and lowering movement of the upper body rest portion 22, the floor frame 2 (exactly the floor plate frame) 2 is provided to lift the upper comforter U hung on the floor board 2 to a predetermined height position on the floor board frame 2. In FIG. 1, a state in which the upper comforter U is lifted up by the upper hook removing device 4 is represented by an imaginary line.

  In this example, the overhanging device 4 is provided on the left and right sides of the base frame 1 and is in a plane parallel to the length direction of the base frame 1 when the upper body rest portion 22 changes from the lying posture to the standing posture. And a plurality of swivel arms 41 and 42 that rise upward on both the left and right sides of the base frame 1 and a rectangular frame that is connected to the free end side of each of the swivel arms 41 and 42 to hold the upper comforter U. It is comprised with the canopy frame 43 to form.

  Two turning arms 41, 42 are provided on each of the left and right sides of the base frame 1 so as to be turnable in the vertical direction. Of these, the pair of left and right turning arms 41, 41 provided at the center of both sides serve as a driving node. Each end thereof is connected to a bracket 12 of the base frame 1 by a fulcrum shaft P2 for turning, and a gear 5 that meshes with the gear 3 is fixed to the fulcrum shaft P2.

  Also, the pair of left and right turning arms 42 and 42 provided at the front portions on both sides (the side of the lying person) of the base frame 1 is a follower that turns following the turning arms 41 and 41 on the driving side. Each end is configured to be knotted by a fulcrum shaft P3 to a bracket 13 formed at the upper edge front portion of the side plate 11 of the base frame.

  On the other hand, as can be seen in FIGS. 1 and 2, the canopy frame 43 is formed between the pair of left and right side links 43 </ b> A and 43 </ b> A connecting the free ends of the swing arms 41 and 42 and the pair of left and right swing arms 41 and 41. The first horizontal shaft 43B installed between the first horizontal shaft 43B and the second horizontal shaft 43C installed between one end of the side link 43A (on the pair of left and right turning arms 42) in parallel with the first horizontal shaft 43B. It consists of.

  In particular, one end on the foot side of the upper comforter U (the side covering the feet of the lying person) is locked to the first horizontal shaft 43B by a string or a belt, and the second horizontal shaft 43C is indicated by a dotted line in FIG. As shown in the figure, an intermediate part of the upper comforter U (the folded part of the upper comforter U that is folded up by folding the head side, that is, the side covering the chest of the lying person) is wound.

  And, according to the overhanging device 4 according to the above, when the upper body rest portion 22 of the floorboard frame 2 is in the lying posture, the swing arms 41 and 42 also maintain the lying posture along both side edges of the floorboard frame 2, When the upper body rest portion 22 changes to the standing posture, the driving force is transmitted to the swing arms 41 and 41 via the gears 3 and 5, so that the swing arms 41 and 42 are centered on the fulcrum axes P2 and P3. The upper comforter U is turned upward in the opposite direction to the upper body rest portion 22 and rises to the left and right sides of the base frame 1, whereby the upper comforter U held in a folded state on the canopy frame 43 is equivalent to the length of the turning arms 41 and 42. Only can be carried on the floorboard frame 2.

  In FIG. 1, the lengths of the swivel arms 41 and 42 are different, but it is preferable that the lengths are the same because the canopy frame 43 can be deployed horizontally. However, the combined length of the swivel arm 42 and the side link 43A is set to be longer than the distance from the fulcrum axis P3 of the swivel arm 42 to the free end of the swivel arm 41. 42 and the side link 43A are bent upward (see the swivel arm 42 and the side link 43A shown by the solid lines in FIG. 1), whereby the swivel arm 42 and the side link 43A are turned in the opposite direction. The canopy frame 43 is developed above the floorboard frame 2 when the swivel arms 41 and 42 are swung upward by performing a swivel operation.

  Here, a slip stopper made of a rubber material or a plurality of protrusions is provided on the second horizontal shaft 43C so that the upper comforter U lifted by the upper hook removing device 4 does not hang down, or the first horizontal shaft 43B Although it is preferable to provide a third horizontal shaft (not shown) between the second horizontal shaft 43C and the second horizontal shaft 43C and the third horizontal shaft, In order to avoid contact with the lying person at times, in particular, the both sides are bent downward so that the height of the lying person does not hit even when standing on the knee, and the gate shape (reverse concave shape including the arch shape) is formed. .

  Next, the configuration of the floorboard frame and its operation mechanism will be described with reference to FIG. 3. The central rest portion 21 is connected to the bracket 12 of the base frame 1 at one end on the upper body rest portion 22 side at the fulcrum shaft P4. Then, the lower leg rest portion 23 side turns in the vertical direction around the fulcrum axis P4. In addition, although the triangular cam body 6 which protrudes in the base frame 1 is provided in the bottom part of the center rest part 21, the effect | action is mentioned later.

  On the other hand, the upper body rest portion 22 has one end portion on the side of the central rest portion 21 connected to the bracket 12 of the base frame 1 at the fulcrum axis P1 as described above, and is vertically moved around the fulcrum axis P1. It is designed to turn. In particular, as is clear from FIG. 3, the turning fulcrum (fulcrum axis P1) of the upper body rest portion 22 is set at a position higher than the turning fulcrum (fulcrum axis P4) of the central rest portion 21. According to this, when the upper body rest portion 22 turns around the fulcrum axis P1 and changes from the lying posture to the standing posture, the mattress D2 on the upper body rest portion 22 and the mattress D1 on the central rest portion 21 are subjected to bending pressure. Is prevented from rising to the recumbent side at the boundary part between the two, so that the recumbent does not feel uncomfortable as the waist is compressed, and the bending pressure on the boundary part of the mattresses D1 and D2 is reduced. Therefore, the standing motion of the upper body rest portion 22 can be smoothly performed under a low load.

  Reference numeral 7 denotes a drive mechanism that changes the upper body rest portion 22 from a lying posture to a standing posture, which includes a drive source 71 (reversible motor) attached to the base frame 1 and a screw shaft 72 that is rotationally driven by the drive source. And a slider 73 that moves in the axial direction when the screw shaft 72 is rotationally driven. Among these, the screw shaft 72 is provided along the longitudinal direction of the base frame 1, and both ends thereof are rotatably supported by bearing units 74 fixed to the side plate 11 of the base frame 1.

  The slider 73 is formed by integrating a nut portion 73A that is screwed onto the screw shaft 72 and a slide plate 73B that is in sliding contact with the side plate 11 of the base frame 1. The slide plate 73B has a long hole that extends in the vertical direction. 73C is drilled.

  The screw shaft 72 and the slider 73 are provided opposite to the left and right sides of the base frame 1 (only one side is shown in FIG. 3), and the pair of left and right slide plates 73, 73 are at the position of the long hole 73C. A horizontal shaft 75 is stretched over. The horizontal shaft 75 and the bracket 22 </ b> 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 articulated arm 76 acts to push up the upper body rest portion 22 from below while gradually rising. The rest portion 22 turns upward about the fulcrum axis P1 to change from the lying posture to the standing posture, and the overhanging device 4 shown in FIG.

  In addition, according to the bed provided with the overhanging device according to the present invention, when the upper body rest portion 22 is changed from the lying posture to the standing posture, the lower leg rest portion 23 is moved in the base frame 1 in conjunction with this. A movable frame 8 that moves from the side to the upper body rest 22 side is provided.

  The movable frame 8 is connected to the slider 73 via the horizontal shaft 75, and when the slider 73 moves to the right in FIG. 3, the movable frame 8 accompanies the slider 73 and moves in the same direction. Yes.

  In particular, a lower leg rest portion 23 that is not connected to the central rest portion 21 is integrally fixed to the upper surface portion of the movable frame 8, and movement guides of the movable frame 6 are provided on the left and right side plates 11 of the base frame 1. A pair of two guide rails 14 and 15 are provided on the left and right. In this example, the guide rails 14 and 15 are slits formed 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 of the guide rails 14 to extend the length of the slider. A guide roller 81 provided in the movable frame 8 is fitted into the other guide rail 15 and inserted into the hole 73C. As shown in FIG. 4, a guide roller 82 that is fitted into the guide rail 14 and the long hole 73 </ b> C of the slide plate is also provided at the end of the horizontal shaft 75.

  Thus, when the slider 73 moves to the right in FIG. 3 to erect the upper body rest portion 22, the movable frame 8 also moves from the lower leg rest portion 23 side to the upper body rest portion 22 side along the guide rails 14 and 15. Moving.

  When the movable frame 8 starts moving toward the upper body rest portion 22 side, the movable frame 8 is converted into an inclined posture while being lowered by the shape of the end portions of the guide rails 14 and 15.

The main body portion of the driving source 109 is swingably supported by a bracket 103A fixed to the column 103, and the tip of the telescopic rod 109A extending from the main body portion is supported. Connected to the lever 106.

  On the other hand, a canopy frame 110 that forms a frame for holding the upper comforter is connected to the free ends of the swivel arms 104 and 105. The canopy frame 110 includes a pair of left and right side links 111 and 111 to which the free ends of the swivel arms 104 and 105 are connected, and a first horizontal shaft 112 installed between one end portions of the both side links 111 and 111. The second horizontal shaft 113 is provided between the other end portions of the side links 111 and 111 in parallel with the first horizontal shaft 112.

  In particular, one end of the upper comforter on the foot side (the side covering the feet of the lying person) is locked to the first horizontal shaft 112 by a string or belt, and the second horizontal shaft 113 is excluded when the upper comforter is excluded. One end of the upper comforter on the head side (the side covering the chest of the lying person) is wound around.

  The length of the first horizontal shaft 112 and the second horizontal shaft 113 can be adjusted according to the width of the bed in the same manner as the horizontal material 101 that connects the base materials 100 and 100. Further, as shown in FIG. 18, the second horizontal shaft 113 is bent downward at both ends so as to have a gate shape (a reverse concave shape including an arch shape), and the canopy frame 110 is lowered by the downward swing of the swing arms 104 and 105. Even when the second horizontal shaft 113 does not interfere with the lying person on the bed.

As is clear from this figure, according to the above-described overhanging device, the pair of left and right base materials 100, 100 are connected by the horizontal member 101 passed under the bed B, and the whole is assembled. The swivel arms 104 and 105 are positioned on both the left and right sides. The swivel arms 104 and 105 swivel up and down in a plane parallel to the length direction of the bed B, and the canopy frame 110 connected to the free end side thereof is moved up and down while maintaining a horizontal state.

  Further, when the upper comforter U is removed as described above, the canopy frame 110 is moved up to a predetermined height position on the bed B with one end portion of the head B side wrapped around the second horizontal shaft 113. However, when the canopy frame 110 is lowered, the one end portion of the upper comforter U can be removed from the second horizontal shaft 113 and can be hung on the chest of the lying person.

  Here, as is apparent from FIG. 20, the bed B has a floorboard frame 200 in which an upper body rest part 201, a central rest part 202, a lower leg rest part 203, and a foot rest part 204 are connected in a freely bending manner. When the drive source 205 (cylinder device) is driven, the upper body rest portion 201 changes from the lying posture to the standing posture, while the lower leg rest portion 203 is bent downward and the foot rest portion 204 is folded on the back side. Thus, the entire structure is converted into a chair shape having the central rest portion 202 as a seat portion. However, the upper device according to the present invention is not limited to that type of bed B, and is attached to various beds. The upper comforter U can be eliminated while being held on the canopy frame 110 raised on the bed.

  Next, a description will be given of a modified example of the canopy frame. The canopy frame 120 shown in FIGS. 21 to 24 has a configuration in which a pair of left and right side links 121 and 121 are connected by a plurality of ribs 122A. It is set as the holding | maintenance part 122 which hold | maintains the upper comforter U in the state hung from the leg part of the lying person on the bed B (floor board frame 2,200). According to this, since the leg part of the lying person is not compressed by the upper comforter U, the sleeping comfort is good, and the heater can be arranged in the holding part 122 to heat the lying person's feet.

  In particular, each rib 122A has an arch-like shape that is curved upward so as not to interfere with the legs of the lying person on the bed, and a tunnel-like cavity that can accommodate the lying person's legs is formed inside the rib 122A. Is done. An upper comforter U is placed on the holding part 122 so as to cover the leg part of the lying person, and the head side of the upper comforter U projects from the holding part 122 to cover the breast part of the lying person. Further, a hanging curtain 123 is attached to a rib 122A located on the foot side of the lying person in the holding portion 122, and the opening part on the foot side of the lying person is closed by the hanging curtain 123.

  The canopy frame 120 is also connected to the free end side of the swivel arms 41, 42/104, 105 shown in FIGS. 1, 16, etc., and is raised and lowered on the bed, but the upper comforter U is excluded by the rise. In some cases, it can be placed on the holding portion 122 in a state of being folded into two of the upper comforters U as shown in FIG.

  Although the present invention has been described above, the holding portion 122 is not limited to being formed by the plurality of ribs 122A, and may be formed by a semicircular plate material that covers the entire leg portion of the lying person. Further, instead of the hanging curtain 123, a hard plate such as wood can be used.

  The present invention relates to a bed top-riding device mainly intended for a care recipient such as a disabled person or a sickly elderly person.

  In general, people with disabilities, sick elderly people, hospitalized patients after surgery, etc. are forced to live on the floor, but as bedridden time increases, physical function declines, so the decline in muscle strength is recovered. Walking training is considered to be extremely effective for stimulating the cerebrum.

  However, those who have a major functional disorder cannot get up on their own, and they need to be cared for by their relatives and specialized caregivers during meals, excretion and bathing.

  In particular, when you wake up on the bed and eat or walk away from the bed, the upper comforter may be in the way, but the incapacitated caregiver cannot jump off the upper comforter, Even if this is done by a caregiver, it may be difficult to place the upper comforter.

Therefore, a stable board which is installed on the floor under the bed, the stabilizing plate to vertically movable main pillars which are installed vertically and, enabling opening and closing this is mainstay connected to an upper portion of at upper bed There has been proposed an automatic comforter device that has an openable / closable dome and an upper comforter that is held by a lattice frame-like frame that constitutes the openable / closable dome (for example, Patent Document 1).

  In addition, a hanging sheet covering unit having a pair of left and right telescopic poles is provided at the rear part (foot side) of the bed frame body, and the cloth body extends on the bed frame body due to the extension of the telescopic pole, and the telescopic pole A bed has been proposed in which the cloth body is folded and stored on the hanging sheet covering unit side when the size is reduced (for example, Patent Document 2).

  Furthermore, a device has been proposed in which a support is provided on one side of the base, and one end edge of a holding frame forming a lattice shape is rotatably attached to the upper part of the support so that the holding frame on which the upper comforter is hung can be flipped up. (For example, Patent Document 3)

JP 2002-177342 A JP 2004-290348 A JP-A-10-57427

  However, according to Patent Document 1, a dedicated drive source (power source) is provided to perform the vertical motion of the main pillar and the open / close operation of the open / close dome, and the drive source is controlled to operate based on the switch input or the sensor input. Therefore, there is a problem that the device cost becomes high.

  In addition, since the entire apparatus is installed on one side of the bed, it is difficult to provide care, and when the apparatus is installed on one side of the bed where the backrest part (upper body rest part) that supports the upper body of the lying person performs the undulation action, If the backrest part of the bed is accidentally raised while the open / close dome is closed, there is a risk that the open / close dome will be destroyed, and the lying person will be between the open / close dome and the backrest part of the bed. There is a risk of falling into breathing difficulty.

  Further, since the upper comforter is attached to the lower part of the opening / closing dome by Velcro (registered trademark), it is difficult to attach the upper comforter to the opening / closing dome with a thick heavy upper comforter.

  On the other hand, in Patent Document 2, since both sides of the upper comforter (cloth body) are supported by the cantilevered telescopic poles, the telescopic poles are arranged in the length direction of the bed unless they are extremely lightweight. It cannot be extended and retracted, and the hanging seat covering unit that includes the telescopic pole is installed on the foot side of the lying person, so it can only enter and exit from both the left and right sides of the bed, changing to a chair shape There is a problem that the seat covering unit becomes an obstacle when walking up from a sitting posture in a bed.

  Further, in Patent Document 3, since the support column always stands on the side of the lying person, it is difficult to care for the lying person, and the holding frame is supported in a cantilevered state. It is difficult to use, and when the holding frame is flipped up, there is a high possibility that the upper comforter will slide down.

  The present invention has been made in view of the circumstances as described above, and an object of the present invention is to provide an upper exclusion device that can be reliably excluded without being dropped on the floor even with a thick upper comforter attached to various beds. It is to provide.

In order to achieve the above object, the present invention

And a second horizontal shaft (43C, 113) around which an intermediate portion of the upper comforter (U) or one end portion on the head side of the upper comforter (U) is wound, and the canopy frame (43, 110) is The swivel arm (41, 42, 104, 105) is moved up and down while holding the upper comforter (U) on the bed by a swiveling operation.

Moreover, it is a top exclusion device that lifts the upper comforter (U) that is attached to the bed and is hung on the bed to a predetermined height position,
Two pairs of swivel arms (41, 42, 104, 105) that are arranged two on each of the left and right sides of the bed so as to be able to swivel up and down in a plane parallel to the length direction of the bed, A canopy frame that forms a frame for holding the upper comforter (U) by connecting to the free end side opposite to one end portion on the fulcrum side serving as the center of rotation of the swivel arms (41, 42, 104, 105). 120),
The canopy frame (120) has a holding part (122) that holds the upper comforter (U) in a state of floating on the bed from the lying person's leg, and the holding part (122) is the lying person's leg. And a plurality of ribs 122A on which the upper comforter (U) can be folded and placed when the canopy frame (120) is raised, and the canopy frame (120) is The swivel arm (41, 42, 104, 105) is moved up and down while holding the upper comforter (U) on the bed by a swiveling operation .

  According to the overhanging device according to the present invention, the swivel arm can be swung up and down in a plane parallel to the length direction of the bed, so that the swivel arm lies on both the left and right sides of the bed. Since the swivel arm does not become an obstacle for nursing care, and the swivel arms are arranged on both the left and right sides of the bed, the canopy frame that forms the frame for holding the upper comforter is connected to the free end side of the swivel arm. The frame does not tilt to the left and right, so that the upper comforter can be removed while being held by the canopy frame. Further, in the state where the upper comforter is removed while being held by the canopy frame, an effect that the upper comforter can be dried is also obtained.

  The canopy frame has a first horizontal shaft for locking one end on the foot side of the upper comforter, and an intermediate portion of the upper comforter or one end portion on the head side of the upper comforter is wrapped around the first horizontal shaft. Since it has a second horizontal shaft, it can securely hold even a thick heavy upper comforter carried on the floorboard frame to prevent it from hanging down, and the top removal device is integrated with the bed frame. It is possible to care for the lying person from both sides of the bed in a state where it is not equipped with space and the upper comforter is not lifted up.

  In addition, in the canopy frame having a holding part that holds the upper comforter in a state of being floated from the legs of the lying person on the bed, even if a thick upper comforter is used, the legs of the lying person are not compressed, Both legs can be moved freely, and when the canopy frame is raised, the upper comforter can be folded over the holding portion to prevent the upper comforter from slipping down.

As shown in the figure, an intermediate part of the upper comforter U (the folded part of the upper comforter U that is folded up by folding the head side, that is, the side covering the chest of the lying person) is wound.

  And, according to the overhanging device 4 according to the above, when the upper body rest portion 22 of the floorboard frame 2 is in the lying posture, the swing arms 41 and 42 also maintain the lying posture along both side edges of the floorboard frame 2, When the upper body rest portion 22 changes to the standing posture, the driving force is transmitted to the swing arms 41 and 41 via the gears 3 and 5, so that the swing arms 41 and 42 are centered on the fulcrum axes P2 and P3. The upper comforter U is turned upward in the opposite direction to the upper body rest portion 22 and rises to the left and right sides of the base frame 1, whereby the upper comforter U held in a folded state on the canopy frame 43 is equivalent to the length of the turning arms 41 and 42. Only can be carried on the floorboard frame 2.

In FIG. 1, the lengths of the swivel arms 41 and 42 are different, but it is preferable to set the lengths to the same length because the canopy frame 43 can be deployed horizontally. However, the combined length of the swivel arm 42 and the side link 43A is set to be longer than the distance from the fulcrum axis P3 of the swivel arm 42 to the free end of the swivel arm 41. 42 and the side link 43A are bent upward (refer to the swivel arm 42 and the side link 43A shown by solid lines in FIG. 1), so that the swivel arm 42 and the side link 43A swivel in opposite directions. The canopy frame 43 expands above the floorboard frame 2 when the swivel arms 41 and 42 are swung upward by performing the operation .

  Here, a slip stopper made of a rubber material or a plurality of protrusions is provided on the second horizontal shaft 43C so that the upper comforter U lifted by the upper hook removing device 4 does not hang down, or the first horizontal shaft 43B Although it is preferable to provide a third horizontal shaft (not shown) between the second horizontal shaft 43C and the second horizontal shaft 43C and the third horizontal shaft, In order to avoid contact with the lying person at times, in particular, the both sides are bent downward so that the height of the lying person does not hit even when standing on the knee, and the gate shape (reverse concave shape including the arch shape) is formed. .

  Next, the configuration of the floorboard frame and its operation mechanism will be described with reference to FIG. 3. The central rest portion 21 is connected to the bracket 12 of the base frame 1 at one end on the upper body rest portion 22 side at the fulcrum shaft P4.
