Wheelchair conversion base

The invention relates to a wheelchair conversion base, which adopts a wheelchair chassis as a base platform and connects the separated seat cushions thereon, which are respectively a part of a hospital bed and a car seat.

The aging of the demographic structure, disease patterns, changes in family structure and improvement in quality of life all affect the development of elderly care in advanced countries. The loss of mobility has always been the most worrying thing for the elderly, and it is also the most common disability problem for the elderly. Most disabled elderly people are hidden in the community and family. Their care pressure and burden are unimaginable to most people. The children are disabled for long-term care, not only the physical and mental health of the red light, family caregivers take care of up to 10 hours a day, far higher than the average office worker's 8 hours, and always wake up at night, no There is no income on vacation, and I often live a life that is isolated from the outside world and even suffer from depression. If we can understand the actions of the disabled and the need and problems of social interaction, we can reduce the care of the elderly and make it easy for the elderly or those with limited mobility to live easily.

In order to cope with the changes in the environment and the advancement of medical technology, designing life aids to assist the elderly has become a key research project in the industry today. Wheelchairs are widely used as ancillary tools for caring for patients. The care process often requires patients to be in wheelchairs. Move with beds, car seats, etc. for related care. This item works on the movement of the wheelchair and the moving targets. The conventional wheelchair has limited function. Therefore, it is usually necessary for the caregiver to hold the patient to move, which causes the caregiver to not easily move the patient, and even the process of moving the patient leads to the patient. Discomfort or further injury.

At present, the biggest problem for the movement of patients with ill or long-term illness is that it will cause a lot of physical burden and physical injury to their caregivers. Therefore, patients should be moved from the bed to the wheelchair. When moving from a wheelchair to a vehicle such as a car, the caregiver usually has to rely on the self-power and use the waist as a fulcrum to move the patient, not only often hurting the waist of the caregiver, and In the case of emergency transportation or traffic intersections and important passages of buildings, it often causes many inconveniences and operational problems.

The main purpose of the invention is to enable the seat cushion on the wheelchair to be combined with the car seat and the bed movement through the slide rail group, which not only facilitates the movement of the patient between the wheelchair, the bed and the car seat, but also facilitates the care. It is more convenient and safe to move patients to improve the long-term care quality of patients.

In order to achieve the foregoing objects and effects, the present invention provides a wheelchair conversion base and can be mutually moved and converted with a target, including: a wheelchair and a slide group, wherein: the wheelchair has a base and a seat cushion slidably mounted on the base The bottom of the base is provided with a rotating wheel, the rotating wheel provides the base to move relative to the ground, and the seat cushion can slide laterally relative to the base, and the two sides of the base respectively have armrests corresponding to the sliding direction of the seat cushion, and the handrail extends upward On both sides of the seat cushion; The target object is provided with a reserved slot, and the two ends of the slide rail group are respectively disposed between the wheelchair base and the reserved slot of the target object, and the slide rail group is disposed in a reserved slot of the target object, and the base is provided with a slip. The slot can be slid along the rail set to be positioned between the target and the wheelchair.

The wheelchair shifting base further includes a locking group disposed on the seat cushion and movably fixed to the rail group, the locking group including a spring providing a handle, and providing a spring that is retracted by the handle when the handle is received by the seat cushion.

The above-mentioned wheelchair conversion base, wherein the seat cushion is provided with a sliding slot which is slidably disposed on the slide rail group, and the slide rail group comprises a fixed slide rail and a telescopic slide rail fixed on the reserved slot of the target object. The fixed slide rail has an extended end extending toward the outer side of the target object, and the telescopic slide rail has a multi-section type, and the opposite ends are respectively a fixed end and a corresponding end, and the fixed end of the telescopic slide rail is fixed on the base, and the telescopic The corresponding end of the slide rail can be retracted toward the fixed end and combined with the extended end of the fixed slide rail, so that the seat cushion can slide between the fixed end of the telescopic slide rail, the corresponding end and the fixed slide rail.

In the wheelchair conversion base, the seat cushion side is pivotally connected with a cushion that can swing upward relative to the seat cushion and is at the same level as the seat cushion, and the cushion and the seat cushion can be positioned together with the reserved groove of the target.

The aforementioned wheelchair conversion base, wherein the target is a hospital bed and a car seat.

The fourth picture is a three-dimensional diagram of the creation of the seat cushion and the bed.

The fifth figure is a three-dimensional schematic diagram of the present invention implemented in a car seat.

Referring to the first figure of the drawing, a wheelchair 1 is shown. The wheelchair 1 has a base 11 and a seat cushion 12 slidably disposed on the base 11. The bottom of the base 11 is provided with a four-wheel 13 and a runner 13 The base 11 is provided to move relative to the ground, and the runner 13 is in a universal rotation mode, and the seat cushion 12 can slide laterally relative to the base 11. The two sides of the base 11 respectively have an armrest 14 corresponding to the sliding direction of the seat cushion 12 The armrest 14 extends upwardly on both sides of the seat cushion 12; a pedal 15 is provided on the front side of the base 11 to provide stepping of the patient's foot. The seat cushion 12 is pivotally coupled to a cushion 16 that is swingable upwardly relative to the seat cushion 12 and at the same level as the seat cushion 12, the cushion 16 providing a user's back abutment support.

Referring to the second figure, the target 2 is provided with a reserved slot 21, and the two ends of the slide set 3 are respectively disposed between the base 11 of the wheelchair 1 and the reserved slot 21 of the target 2, and the slide rails. The group 3 system is disposed in the reserved slot 21 of the target 2, and the seat cushion 12 is provided with a chute 17 and is slidable along the rail group 3 to be positioned between the target 2 and the wheelchair 1.

The target 2 is exemplified by a hospital bed, and may also be a bed for general home care, and a reserved groove 21 is provided on the side of the target 2, and the periphery of the reserved groove 21 is a mattress for providing a patient's sitting and lying function. . Thus, the wheelchair 1 can be moved to the side of the object 2, and the armrest 14 on the side close to the object 2 can be pivoted downward toward the base so that the side of the seat cushion 12 facing the object 2 is not blocked by the armrest 14, and Operating rail group 3 corresponding to the reserved slot 21 of the target 2, so that the caregiver can push and pull the cushion 12 toward the target 2 until the cushion 12 is aligned with the reserved groove 21 of the target 2, and can be smoothly placed in the wheelchair The patient on the seat cushion 12 of the type 1 is moved to the bed, and similarly, the type of the bed can be moved to the wheelchair 1. The foregoing embodiment converts the movement between the wheelchair and the bed (target). Referring to the fifth embodiment, the above mechanism and actuation principle can also be applied between the wheelchair 1 and the car seat 22. Therefore, the present invention can not only facilitate the movement of the patient between the wheelchair 1 and the bed and the car seat 22, but also facilitates the caregiver to move the patient in a convenient and safe manner, thereby improving the long-term care quality of the patient, and the patient achieves the purpose of the present invention accordingly. efficacy.
