Compound swing wheelchair

The composite swinging wheelchair of the present invention is known to provide an inconvenience to the person who is inconvenient to move, and to stand in front of the ground and swing back and forth to provide a comfortable ride.

The medical system has made major breakthroughs and developments in terms of appliances, uses, and theory to provide patients with better medical services. Among the many medical devices, the most widely used ones are crutches and wheelchairs. In terms of use, it is used for assisting patients to travel, and the difference between the two is that the cane is used by patients who can walk on their own, and the purpose of the wheelchair is to provide a patient who cannot walk, without spending a large amount of money. The strength of the body to support their body, so the wheelchair is also used in the market.

With the difference in the age group, the number of the elderly is gradually increasing. The average family cannot take care of the elderly because of their busy work. Therefore, they will buy a wheelchair to provide a ride, which is convenient for all actions, but the wheelchair is designed unless In addition, some people help to push the positioning. Otherwise, when the elderly want to set a certain rest, it is easy for the wheelchair to move by the bumps on the ground. The elderly can't react immediately and lead to dangerous increase. The wheelchair design is easy to ride for a long time. There will be problems of uncomfortableness, so how to make the elderly have no danger and uncomfortable problems in the fixed-point rest, and the related companies have introduced safety and comfort in order to provide the elderly with a fixed point of rest. A wheelchair with safety and comfort.

Please refer to the Republic of China Patent Bulletin No. 308052 "Swinging Wheelchair", The utility model comprises a wheelchair body which can be accommodated when the human kidney is seated, and a fixing frame which is respectively erected on two sides of the wheelchair body. The front side of the fixing frame is provided with a set of small round diameter runners, and the rear left and right ends. The side is respectively a pivoting wheel with a larger circular diameter, and a pair of movable connecting members are respectively pivotally arranged on the two sides of the fixed frame relative to the wheelchair body to enable the pivoting center of the movable frame The predetermined angular offset movement is performed, and the bottom end of the connecting member is coupled to the opposite end side of the wheelchair body, thereby achieving the swaying of the rocking chair before and after the simulated rocking chair.

Although the above-mentioned wheelchair provides the user to ride, and can simulate the swinging of the rocking chair to increase the entertainment, but the above-mentioned comfort does not exist, and the lack of positioning and comfort of the elderly during the fixed-point rest cannot be provided. Therefore, relevant industry players must further think about how to improve to be more convenient for the elderly.

In view of the above-mentioned "swing wheelchair", the inventors have devoted a lot of time to research related knowledge, and compared various advantages and disadvantages, and carried out research and development of related products, and after many experiments and tests, finally launched a " The compound swinging wheelchair is intended to improve the above-mentioned descriptions to meet the needs of the public.

The main purpose of the present invention is to provide a person with reduced mobility in addition to having the function of providing travel, and further capable of achieving a comfortable rest by swinging back and forth when fixed-point rest, which is to improve the conventional wheelchairs.
