Description

  The present invention relates to an operation of a standing auxiliary wheelchair or a standing chair and workability of a user and standing assistance or a recumbent variable lifting device.

  Conventional wheelchairs have been devised mainly for convenience and safety related to forward / backward and left / right movements, and improvements such as electric running and raising / lowering seating have been made. The position was slightly changed, and lying on the floor was a basic structure.

  Conventional standing chairs are not equipped with appropriate assistance according to the posture of the user, depending on the user's body shape and degree of inconvenience, and are equipped with equipment that suppresses the change to the most appropriate height or forward tilt There were still problems, such as not being made abundantly. (For example, see Patent Document 1)

  For a caregiver or caregiver, getting off a wheelchair and laying it in a bed is a work that places a heavy physical burden on the caregiver or caregiver, but the burden on the passenger is particularly high. There were still issues such as a heavy burden on the company. (For example, see Utility Model Document 1)

  In the field of welfare and nursing care, various devices and tools have been devised to reduce the physical burden on caregivers or caregivers. Or, there is a limit such as not being able to reach high places in the workplace, and depending on the standing position, it does not really meet the user's request such as sliding down or falling forward. (For example, see Patent Document 2)

  The above-mentioned conventional wheelchair is a wheelchair with a mechanism that considers convenience mainly for passengers who can run on their own, such as those with weak physical fitness, lower limbs disabled persons or persons with lower body paralysis due to spinal injury accidents, etc. It was necessary to provide appropriate assistance, such as taking necessary items at a high position in the home or workplace. In addition, the shift work of the care recipient requires a large amount of labor of the caregiver, and back pain or back pain is serious and care or assistance at home has been extremely difficult.

  In the conventional stand-up support wheelchair, when the seat plate is raised, the seating position of the seated person with respect to the seat plate is not fixed, and the center of gravity moves in the forward direction of the buttocks as the tilt of the seat plate increases. However, since the buttock will be pushed forward, slipping will eventually occur, which means that it is necessary for the seated person to step forward with back-and-forth movement, which is more dangerous for those who are not used to it. It was an increase in the nature.

  In this standing assistance chair, it is required that the user can use it more safely without sliding down forward in the process of posture change.

  The present invention is intended to solve the basic problems and disadvantages of the configuration of a conventional wheelchair, ensuring the convenience of standing up, such as returning to society for wheelchair users, The object is to provide a comfortable and functional wheelchair so that it can be collinear with a normal healthy person.

  In order to achieve the above object, the present invention takes the following technical means. That is, the support member of the seating chair portion on which the seated person sits with the feet attached to the step surface through the standing assistance or the stepless stepless variable wheelchair according to the present invention is set to 1 each on the left and right. The pointed saddle that supports the crotch and buttocks and is fitted to the seating chair part attached to the upper surface of the seating frame that is composed of a set of parallel links is lifted and slid abruptly. It is characterized by lifting the position and supporting the crotch part and the buttocks to eliminate slipping of the upper limbs.

  In the wheelchair having the auxiliary function according to the invention, a wheelchair body provided with a movable vehicle body, a seating frame constituted by a pair of left and right parallel links provided on the wheelchair so as to be tiltable, and the seating frame On the other hand, it is characterized in that a seating chair provided to be tiltable via a pivot near the front part, a lifting mechanism provided on a wheelchair body to tilt the seating frame, and tilting up and down can be freely adjusted.

  In the present invention, it is preferable that the simultaneous support device for the buttocks or scapula around the seating chair main body is provided with means for moving the device forward when the standing assistance operation occurs. This greatly contributes to the comfort of wheelchair users because it prevents the restraint degree of the lower leg calf support device from being tightened moderately when standing or sitting.

  The action by the problem solving means is configured by a pair of left and right parallel links provided so as to be tiltable on the wheelchair when a user with reduced limb mobility secures a standing state from a seated state. A seating frame, a seating chair provided to be tiltable via a pivot near the front of the seating frame, and a pointed saddle portion on the seating chair portion, and at the time of standing assistance variable, Since the pointed saddle portion is raised at the crotch region to support the crotch portion and the buttocks, and the upper limbs are prevented from falling off, the standing position can be ensured smoothly.

  The wheelchair can comfortably assist a wheelchair user in returning to the economy and society by ensuring stepless change from a boarding seating posture to a standing posture and allowing vertical movement.

  Another problem-solving means includes a pointed saddle portion that has a pointed saddle portion on the seating chair portion, and is fitted into the seating chair portion in the crotch portion when the standing position is variable. An arc-shaped column that pushes up the pointed saddle and raises and stabilizes the crotch and hips by supporting the crotch and buttocks and eliminating the slipping of the upper limbs. This mechanism may be an electrically-driven standing stepless variable wheelchair configured by a polygonal and telescopic tilting lifting device, and which can assist standing comfortably.

  Since the present invention is equipped with a manual or electrically powered buttocks or sphenoid peripheral simultaneous support device when the standing posture is changed from the sitting posture, the means for moving the device forward as desired by the passenger is provided. In addition to being able to adjust it arbitrarily, it is possible to suppress it with the lower leg calf region support device, so it can be prevented from swinging back and forth and from side to side, and it can be prevented from falling forward, and it has a pointed saddle that fits into the sitting chair. To ensure a smooth standing state with a standing or recumbent stepless variable wheelchair that features a device that prevents the dangerous movement such as slipping down by supporting and stabilizing the crotch or buttocks. Can do.

  As described above, the standing or recumbent stepless variable wheelchair of the present invention is a thing that can be operated easily by the boarding user, dispels the anxiety about use, and feels comfortable and comfortable. The use of the left and right spaces is equivalent to that of a normal healthy person, so it can be used to open up the first step of rehabilitation for people with physical disabilities and contribute to socio-economics. It serves as a pioneer in the age of joint participation in the disabled.
