Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a wheelchair for nursing care suitable for use with care recipients such as the physically handicapped, the elderly, the sick, and the like. The present invention relates to a wheelchair for nursing care that is configured so that nursing work such as washing and excretion can be easily and easily performed while a care recipient is seated.
[0002]
[Prior art]
Conventionally, as this kind of wheelchair for nursing care, it is necessary to put a care recipient in a wheelchair, move it to a bathroom, and perform washing, wiping, bathing, etc. with the care recipient in a wheelchair. There are various proposals that can be made. Therefore, this kind of wheelchair for nursing care is generally provided with an elevating means so that the height of the seat portion can be changed in order to facilitate nursing work such as washing, wiping, bathing, etc. for the care recipient. Wheelchairs have been proposed.
[0003]
For example, at the time of bathing, the seat portion is located in the bathtub, the trolley portion is located outside the tub, and a liftable wheelchair for bathing in which the seat portion and the trolley portion are connected by a support, There has been proposed a device in which a lifting / lowering function unit including a direct-acting cylinder capable of arbitrarily changing a distance between a seat portion and a bogie portion is provided between the seat portion and the bogie portion (see Patent Document 1).
[0004]
Further, as a similar lift-type wheelchair, a pair of X-shaped frames provided opposite to each other under and below the seat surface can be opened and closed so that they can be folded in the left-right direction. A base portion suspended between the front and rear X-shaped frames, a telescopic member including a vertically extending hydraulic cylinder mounted on the base portion, and a seat side edge mounted on an upper portion of the telescopic member. And a connecting bar connecting the upper end portions of the pair of front and rear X-shaped frames with each other in the front-rear direction. There has been proposed a configuration in which the edge bar protrudes forward while rising, and the seat surface rises (see Patent Document 2).
[0005]
Alternatively, as a similar liftable wheelchair, a seating surface formed separately from the body frame is provided, and four front, rear, left and right corners of the seating surface are telescopic members comprising a plurality of hydraulic cylinders attached to the body frame, respectively. There is also proposed a device that is held up and down on a vehicle body frame via a vehicle (see Patent Document 3).
[0006]
On the other hand, as this kind of wheelchair for nursing care, it is preferable that a person in need of care can easily transfer from the bed to the wheelchair or from the wheelchair to the bed. Therefore, in the conventional wheelchair, various proposals have been made regarding the retreating movement of the armrest, the retreating movement of the footrest, the position of the wheel, and the like so that one side of the seat can be sufficiently approached to the side of the bed.
[0007]
For example, with respect to an armrest that becomes an obstacle when getting on and off from the side of a wheelchair, a seat (seat) is provided substantially at the center of gravity in a wheelchair main body having a back frame integrally provided on the rear side, and a side surface of the seat is By attaching the armrest so that it can rotate backwards in parallel, the armrest is rotated backwards, the armrest is removed from the side of the seat, and the wheelchair can be laid sideways close to a bed etc. directly from the side of the seat One that facilitates transfer to a bed has been proposed (see Patent Document 4).
[0008]
Alternatively, in a wheelchair provided with an armrest that can rotate upward from a horizontal use state on at least one side of the seat, the upper edge rear end of the armrest is on the back side of the body frame of the wheelchair, and When the armrest is pivoted upward from the horizontal use state by pivoting to a position lower than the height of the seat portion, a predetermined interval is formed between the front edge frame of the armrest and the handle portion to provide care. There has also been proposed a configuration in which even when a user needs to apply a brake suddenly, the brake operation can be reliably performed without erroneous operation (see Patent Document 5).
[0009]
In addition, for the footrest that becomes an obstacle when getting on and off the wheelchair, the lock on the footrest is released by pushing down the piston rod at the time of getting on and off, and in this state, the footrest is held in the side direction by the action of the spring on the footrest holder without lifting the footrest. (Japanese Patent Application Laid-Open Publication No. HEI 11-327572) has been proposed in which a footrest can be easily rotated to set a position on a side portion, thereby facilitating getting on and off a wheelchair.
[0010]
Alternatively, as the footrest, a mounting portion provided at the end of the swing arm to which the footrest plate is mounted is pivotally supported at the turning base on the wheelchair side, and the footrest plate is supported so as to be able to jump up. When the footrest plate reaches the use position or the retracted position, the swinging arm swings just before the protrusion completely engages with the groove when the footrest plate reaches the use position or the retracted position. Even if the caregiver holds the care recipient in both hands by being provided with the stopper portion and the stopper portion serving as a pair of contact portions assigned to the turning base portion and the mounting portion so as to be regulated, The swing arm can be operated without any burden, and when the footrest reaches the use state, the swing arm will not rattle at all, reducing the burden on the caregiver and realizing smoother and appropriate care. It has also been proposed those (refer to Patent Document 7).
[0011]
In addition, when the wheelchair is moving and traveling, if there are irregularities or steps on the road surface, floor surface, etc., not only will it give discomfort to the care recipient due to the occurrence of vibrations and shocks, but also the surrounding noise due to the generation of moving noise. As a caster applied to a wheelchair for nursing care, the caster applied to the wheelchair for the nursing care needs to support the supporting force and, in addition to this supporting force, the resultant force of the impact force acting on the bracket main body via the wheel separately from the supporting force. A swivel caster has been proposed which is provided around the support shaft mainly composed of the bracket so as to be deformed and provided with a buffer means concentrically fitted with an elastic member so as to absorb and reduce the vibration and the like. (See Patent Document 8).
[0012]
Furthermore, in the wheelchair for nursing care, the opening of the toilet seat is provided in the seating part of the wheelchair for nursing care so that the care recipient can take a nursing care while sitting down so as to reduce the labor of the caregiver. There has been proposed a device in which a notch corresponding to the above is provided so that a care wheelchair can be set on a toilet without raising and lowering a seating portion (see Patent Document 9).

[Problems to be solved by the invention]
However, in the conventional nursing wheelchair, the one described in Patent Literature 1 provided with the elevating means for the seat portion supports the seat portion only by the direct-acting cylinder as the elevating means, so There is an advantage that it is simple and easy to handle and maintain when used for bathing care. However, there is a drawback that the seat is not stable in front, rear, left and right when a care-requiring person is placed on the seat and moved up and down.
[0015]
Therefore, in order to stabilize the seat surface on which the care-requiring person is placed, as shown in Patent Document 2, the seat surface is supported by a pair of front and rear X-shaped frames and a link mechanism. And the handling and maintenance, especially when used for bathing and nursing care, are complicated, which not only increases the manufacturing cost, but also makes it difficult to adapt to stool care with the care recipient sitting. There is.
[0016]
As shown in Patent Document 3, the front, rear, left, and right corners of the seat surface are each supported by a telescopic member including a plurality of hydraulic cylinders. However, it is difficult to handle and maintain when used for bathing care, etc., which not only increases the manufacturing cost significantly but also makes it difficult to adapt to stool care with the care recipient sitting. There are difficulties such as.
[0017]
Also, in the conventional wheelchair for nursing care, when moving from the bed to the wheelchair, or from the wheelchair to the bed, the armrest or footrest is evacuated smoothly for the convenience of the care recipient and the caregiver. It needs to be moved. Therefore, as shown in Patent Document 4, in the case where the armrest is moved rearward of the seat (seat portion), there is an advantage that the armrest is retracted by reducing the turning amount of the armrest, but the armrest moves upward. While turning, the care recipient needs to raise his arm or twist his body to avoid it.
[0018]
As shown in Patent Literature 5, in the case where the pivoting position of the armrest is set on the back side of the body frame of the wheelchair and lower than the height of the seat portion, the retreat armrest is turned at a lower position. As described above, since the armrest pivots while climbing upward, there is a drawback in that the care recipient needs to raise his arm or twist his body to avoid it.
[0019]
As shown in Patent Document 6, it is possible to easily move the footrest to the retreat position by applying a rotating force in the side direction by the action of the spring without manually lifting or turning the footrest. In this case, the structure for supporting the footrest is complicated, the number of parts is increased, and the manufacturing cost is increased.In addition, the evacuation position is the side position of the frame, which obstructs the feet of the caregiver. In particular, there are disadvantages in that handling and maintenance become complicated when used for bathing care and the like.
[0020]
As shown in Patent Literature 7, in order to pivotally support the footrest, a pivot base on the wheelchair side supports a mounting portion of a swing arm to which the footrest is mounted. As described above, in the case of holding so that there is no backlash, the structure for supporting the footrest is complicated, the number of parts is increased, and not only the manufacturing cost is increased, but also the retracted position is located at the side of the frame. The position becomes a hindrance to the caregiver's feet, and there is a drawback that handling and maintenance are particularly complicated when used for bathing care and the like.
[0021]
Further, in the conventional wheelchair for nursing care, when the wheelchair is moved and traveled, the unevenness and unevenness of the road surface and floor surface, etc., generate vibration and noise, etc. In order to avoid the adverse effect of the above, it is necessary to attach a caster provided with a buffer means. Therefore, as shown in Patent Document 8, when an elastic member that deforms in response to an impact force on a wheel is attached to a main body of a bracket that supports the wheel as a buffer, the amount of elastic deformation is limited. Not only is there a problem in durability and maintenance especially when used for bathing care, etc., but also there are drawbacks in that the structure is complicated, the number of parts is increased, and the manufacturing cost is increased.
[0022]
And in the said patent document 9, as a stool-care wheelchair, a seat-type toilet can be easily arranged at a predetermined position without raising / lowering a wheelchair seating part. Handling and maintenance when used for nursing care and the like are not considered at all, and there are drawbacks such as difficulty in adapting as this kind of nursing wheelchair.
[0023]
