Definitions

  • the present invention relates to an assisting apparatus that assists a care receiver in standing up.
  • the PTL 1 describes an assisting apparatus that assists a care receiver in standing up.
  • the assisting apparatus includes a trunk support member for supporting the trunk of the care receiver and underarm support members for supporting the underarms of the care receiver.
  • the trunk support member and the underarm support members can be tilted in the front-rear direction in addition to being moved up and down. Consequently, the assisting apparatus can shift the care receiver from a sitting posture to a standing posture while supporting the trunk and underarms of the care receiver.
  • a further assisting apparatus is disclosed in WO2015/145915A1 .
  • the underarm support members have a U shape opening upwardly and have portions that face the front and rear surfaces of the shoulder in addition to the underarms of the care receiver. Therefore, in order for the underarms of the care receiver to get into the state in which they are supported by the underarm support members when the care receiver boards the assisting apparatus, the care receiver needs to raise his/her shoulders and elbows high. However, it is not easy for a care receiver to raise his/her shoulders and elbows high. Further, for care receivers in need of intensive care, assistance by a caregiver may be required to get the underarms of the care receiver into a state in which they are supported by the underarm support member.
  • the assisting apparatus is an assisting apparatus that supports the upper body of a care receiver and assists the care receiver in standing up.
  • the assisting apparatus includes a base, an elevator provided on the base in a vertically movable manner, a trunk support member formed in a planar shape, being provided to the elevator in a forward-rearward tiltable manner, which supports the trunk of the care receiver by coming into contact with a front surface of the trunk, and an underarm support member, being supported by the trunk support member, which supports an underarm of the care receiver.
  • the underarm support member includes an underarm insertion portion to be inserted into an underarm of the care receiver.
  • the underarm insertion portion is extended from the trunk support member toward the rear of the care receiver so as to be in a boarding orientation when the trunk support member is positioned at a boarding position with respect to the care receiver in a sitting posture, and the underarm insertion portion is extended upward and rearward from the trunk support member toward the care receiver so as to be in a standing-posture orientation when the trunk support member is tilted forward to shift the care receiver to a standing posture.
  • the care receiver in the sitting posture can easily insert the underarm insertion portions into his/her underarms when boarding the assisting apparatus. Consequently, the care receiver in the sitting posture can easily board the assisting apparatus.
  • the care receiver After the care receiver has boarded on the assisting apparatus, the care receiver is shifted from a sitting posture to a standing posture by tilting the trunk support member forward. With the forward tilt of the trunk support member, the underarm insertion portion goes into an orientation (i.e., a standing-posture orientation) that prevents the care receiver from falling rearward. Consequently, when shifting to the standing posture, the underarm insertion portion supports the care receiver in the standing position from below and behind and is, therefore, very safe.
  • an orientation i.e., a standing-posture orientation
  • FIGS. 1 and 2 show the assisting apparatus 1 in a state in which a care receiver M in a sitting posture is boarding on the assisting apparatus 1.
  • the assisting apparatus 1 supports the upper body of the care receiver M and assists the care receiver M in standing up from the sitting posture to a standing posture. Furthermore, the assisting apparatus 1 supports the upper body of the care receiver M and assists the care receiver M in sitting down from the standing posture of the care receiver M to the sitting posture.
  • the assisting apparatus 1 is capable of assisting the transfer and moving of the care receiver M.
  • a "standing posture” refers to a posture in which the lower body of the care receiver M is upright and the posture of the upper body is irrelevant. That is, standing assistance is an assistance for moving the buttocks position of the care receiver M upward. Further, sitting assistance is an assistance for moving the buttocks position of the care receiver M downward.
  • the assisting apparatus 1 includes a base 2, an elevator 3, a pivot section 4, a body support section 5, a control section 6, and the like.
  • the base 2 includes a frame 21, a support column 22 (shown in FIG. 2 ), a fixed cover 23, a footrest 24, a lower leg contact 25, and six wheels 26, 27 and 28.
  • the frame 21 is provided near a floor surface F in substantially horizontal.
  • the support column 22 is erected upward from the center in the lateral direction at the front of the frame 21.
  • An elevator driver 32 being described later, is arranged in the inner space of the support column 22 that has a substantially rectangular cross section.
  • the fixed cover 23 covers and protects the periphery of the lower portion of the support column 22 and an elevator 31 described later.
  • the footrest 24 is fixed at the rear of the top surface of the frame 21 and in substantially horizontal.
  • a feet-shaped contact mark 241 drawn on the upper surface of the footrest 24 guides the position where the care receiver M puts his/her feet.

  • the lower leg contact 25 is arranged across the upright portions of the left and right support arms 251 and extends in the lateral direction.
  • the lower leg contact 25 is a part that comes into contact with the lower legs of the care receiver M and is made of a cushion material.
  • the arranged height of the lower leg contact 25 is adjustable.
  • Wheels 26 to 28, three wheels on both left and right sides of the underside of the frame 21, are provided.
  • Each of the wheels 26, 27 and 28 has a steering function for changing the movement direction and at least a front wheels 26 have a locking function for restricting movement.
  • the frame 21 and the footrest 24 are maintained slightly separated from the floor surface F in a horizontal manner. Due to the steering function of the six wheels 26 to 28, the assisting apparatus 1 is not only capable of moving in a front-rear direction and changing directions but is capable of moving laterally (i.e., moving directly to the side) and spin-turning (i.e., rotating on the spot).
  • the elevator section 3 includes the elevator 31, the elevator driver 32, an elevator cover 33, and the like.
  • the elevator 31 is elongated in the vertical direction and is supported by the rear surface of the support column 22 in a vertically movable manner. In the present embodiment, the elevator 31 moves up and down by vertically moving with respect to the support column 22 but may also be made to move up and down by pivoting with respect to the support column 22.
  • An upper portion of the elevator 31 projects rearward and there is a pivot support 34 toward the rear end of the projection.
  • a pivot driver 42 which will be described later, is arranged inside the upper portion of the elevator 31.
  • the elevator driver 32 arranged inside the support column 22 drives the vertical movement of the elevator 31.
  • the elevator cover 33 covers and protects the periphery and upper part of the elevator 31 and the support column 22.
  • the elevator cover 33 is coupled to the elevator 31, and moves together vertically with the elevator 31.
  • the lower portion of the vertically moving elevator cover 33 always overlaps the outer peripheral side of the fixed cover 23.
  • the pivot section 4 includes a pivot member 41, the pivot driver 42, and a first handle 43.

That is, the upper body of the care receiver M in the standing posture tilts forward by a large amount and the position of the buttocks of the care receiver M is positioned higher than the seat surface of the chair C. The legs of the care receiver M are then almost completely extended.
  • the care receiver M after the care receiver M has boarded the assisting apparatus 1, by tilting the trunk support member 51 forward, the care receiver M is shifted from a standing-assistance operation starting posture of the sitting posture to a standing posture via the ready-to-stand posture.
  • the underarm insertion portion 522a With the forward tilt of the trunk support member 51, the underarm insertion portion 522a goes into an orientation (i.e., a standing-posture orientation) that extends upward and rearward from the trunk support member 51. Consequently, as soon as the assisting apparatus 1 starts the standing-assistance operation and moves toward the standing posture via the ready-to-stand posture, the underarm insertion portion 522a supports the care receiver M from below and behind, which prevents the care receiver M from falling rearward.
  • an orientation i.e., a standing-posture orientation
  • the assisting apparatus 1 is very safe when the care receiver M shifts to the standing posture.
  • the assisting apparatus 1 is very safe when the care receiver M separates from the seat surface of the chair C, that is, when the care receiver M shifts from the ready-to-stand posture to the standing posture.
  • the operation of the sitting assistance of the assisting apparatus 1 is performed by performing the standing-assistance operation in essentially the opposite manner. That is, while the trunk support member 51 tilts rearward, the elevator 31 descends, causing the care receiver M to shift from the standing posture to the sitting posture. The care receiver M in the sitting posture can then easily withdraw the underarm insertion portions 522a from his/her underarms.
  • the caregiver or care receiver M pivots the underarm arm 522 around the fulcrum 521a and moves the underarm insertion portion 522a away from the side of the trunk support member 51. That is, the separation distance between the left and right underarm insertion portions 522a is increased and the trunk of the care receiver M having a large physical size can be brought into contact with the cushion 512 of the trunk support member 51.
  • the care receiver M can easily insert the underarm insertion portions 522a into his/her underarms. Therefore, the care receiver M in the sitting posture can easily board the assisting apparatus 1 without assistance from a caregiver.
  • the assisting apparatus 1 is an assisting apparatus that supports the upper body of the care receiver M and assists the care receiver M in standing up.
  • the assisting apparatus 1 includes the base 2, the elevator 31 provided on the base 2 in a vertically movable manner, the trunk support member 51 formed in a planar shape, being provided to the elevator 31 in a forward-rearward tiltable manner, which supports the trunk of the care receiver M by coming into contact with the front surface of the trunk, and the underarm support members 52, 52 supported by the trunk support member 51, that support the underarms of the care receiver M.
  • the underarm support member 52 includes the underarm insertion portion 522a to be inserted into the underarm of the care receiver M.
  • the underarm insertion portion 522a is extended from the trunk support member 51 toward the rear of the care receiver M so as to be in the boarding orientation.
  • the underarm insertion portion 522a is extended upward and rearward from the trunk support member 51 toward the care receiver M so as to be in the standing-posture orientation.
  • the underarm insertion portion 522a is extended rearward so as to be in the boarding orientation. Consequently, the care receiver M in the sitting posture can easily insert the underarm insertion portions 522a into his/her underarms when boarding on the assisting apparatus 1. Consequently, the care receiver M in the sitting posture may comfortably board on the assisting apparatus 1.
  • the care receiver M After the care receiver M has boarded the assisting apparatus 1, the care receiver M is shifted from the sitting posture to the standing posture by tilting the trunk support member 51 forward. With the forward tilt of the trunk support member 51, the underarm insertion portion 522a goes into an orientation (i.e. a standing-posture orientation) that prevents the care receiver M from falling rearward. Consequently, when shifting to the standing posture, the underarm insertion portion 522a supports the care receiver M in the standing posture from below and behind and is, therefore, very safe.
  • an orientation i.e. a standing-posture orientation
  • the underarm insertion portion 522a becomes a standing-posture orientation that extends upward and to the rear of the care receiver M from the trunk support member 51.
  • the underarm insertion portion 522a rises further.
  • the underarm insertion portion 522a supports the care receiver M in the standing posture from below and behind.
  • the assisting apparatus 1 is very safe when the care receiver M separates from the seat surface of the chair C, that is, when the care receiver M shifts from the ready-to-stand posture to the standing posture.
  • the underarm support member 52 is provided at the front end of the underarm insertion portion 522a, is located on the side of the trunk support member 51, and further includes the shoulder receiving portion 522b for supporting the front of the shoulder of the care receiver M. With the underarm support member 52 having the underarm insertion portion 522a and the shoulder receiving portion 522b, the care receiver M is supported in a stable manner at a position of the underarm insertion portion 522a that is close to the shoulder receiving portion 522b.
  • the care receiver M is supported at the front of the trunk by the trunk support member 51, at the front of the shoulder by the shoulder receiving portions 522b of the underarm support member 52, and at the underarms from below by the underarm insertion portions 522a of the underarm support member 52. Hence, the care receiver M is in a state of being supported stably in the assisting apparatus 1.
  • the underarm support member 52 has an L shape of which one extending portion is the underarm insertion portion 522a, and of which an other extending portion is the shoulder receiving portion 522b.
  • the underarm insertion portion 522a is longer than the shoulder receiving portion 522b.
  • the shoulder receiving portion 522b is relatively short, in a state in which the care receiver M has boarded the assisting apparatus 1, the care receiver M does not feel constricted by the shoulder receiving portion 522b.
  • the underarm insertion portion 522a and the shoulder receiving portion 522b of the underarm support member 52 is formed by a rod-shaped member.
  • the underarm insertion portion 522a is formed from the rod-shaped member into a linear shape
  • the shoulder receiving portion 522b is also formed from the rod-shaped member into a linear shape.
  • the underarm insertion portion 522a and the shoulder receiving portion 522b are provided such that there is an angle therebetween . That is, the underarm insertion portion 522a and the shoulder receiving portion 522b are formed together from the rod-shaped member into a bent shape.
  • the care receiver M may have an impression such that the underarm insertion portions 522a are easy to insert into the underarms. From this, the care receiver M may have a sense such that the assisting apparatus 1 is comfortable to board. Furthermore, in a state in which the care receiver M boards on the assisting apparatus 1, since the underarm insertion portion 522a is a linear rod member, the care receiver M may obtain a sense that the underarm insertion portions 522a are interposed in his/her underarms. That is, the care receiver M can obtain a sense of security that he/she is being supported by the underarm insertion portions 522a.
  • the care receiver M in a state in which the care receiver in the sitting posture boards on the assisting apparatus, it is easy to move the arm back and forth since the underarm insertion portion 522a is a linear rod member. That is, from the viewpoint of the care receiver M, the experience of being on the assisting apparatus becomes favorable. Even if the care receiver M moves his/her arm back and forth, the care receiver M can easily maintain the state of interposing the underarm insertion portions 522a in his/her underarms. From this, the care receiver M can have a favorable experience of being on the assisting apparatus 1 and obtain a sense of security.
  • the underarm insertion portions 522a are formed so as to extend toward the rear of the care receiver M from the center in a vertical direction of the trunk support member 51. That is, the trunk support member 51 supports the trunk of the care receiver M, from the chest portion above the underarms to the abdomen portion below the underarms. Thus, since the trunk of the care receiver M is supported by the trunk support member 51 over a wide range, the sense of security of the care receiver M is favorable.
  • the underarm insertion portions 522a are in a boarding orientation in which they are extended substantially in a horizontal direction.
  • the care receiver M in the sitting posture can easily insert the underarm insertion portions 522a into his/her underarms. Consequently, the care receiver M in the sitting posture may comfortably board on the assisting apparatus 1.
  • the angle ⁇ between the rearward-directed direction vector Nb of the underarm insertion portion 522a and the normal vector Na of the support surface of the trunk support member 51 is an acute angle.
  • the normal vector Na is directed more upward than the rearward-directed direction vector Nb of the underarm insertion portion 522a.
  • the assisting apparatus 1 can achieve compatibility between giving a sense of stability with the forward-tilted trunk support member 51 and facilitating boarding.
  • the angle ⁇ of the rearward-directed direction vector Nb of the underarm insertion portion 522a and the normal vector Na of the support surface of the trunk support member 51 is preferably 10° to 50°, and more preferably 35° to 45°. From this, the assisting apparatus 1 can reliably achieve compatibility between giving a sense of stability with the forward-tilted trunk support member 51 and facilitating boarding.
  • the angle ⁇ between the direction vector Nb and the normal vector Na is preferably 10° to 50°.
  • the underarm support member 52 is provided on the trunk support member 51 in a rotatable manner around the fulcrum 521a provided further toward the front of the care receiver M than the underarm insertion portion 522a.
  • the underarm insertion portion 522a has a boarding orientation that extends from the trunk support member 51 toward the rear of the care receiver M.
  • the care receiver M when the care receiver M inserts the underarm insertion portion 522a into the underarm, the underarm insertion portion 522a rotates around the fulcrum 521a provided at the front so as to match the position of the underarm of the care receiver M. Consequently, the care receiver M can easily get into the assisting apparatus 1 since the position of the underarm insertion portions 522a can be matched with the physique of the care receiver M. Furthermore, even if the underarm insertion portion 522a is rotated about the fulcrum 521a, the underarm insertion portion 522a extends rearward from the trunk support member 51. Consequently, irrespective of the physique of the care receiver M, the care receiver M may easily board on the assisting apparatus 1.
  • the underarm insertion portion 522a has a boarding orientation that extends in a substantially horizontal direction.
