Wheelchair structure device capable of arbitrarily lifting and lowering the occupant

The invention relates to a wheelchair structure device which can arbitrarily move up and down and sway the occupant, in particular, a wheelchair can be lifted up and down and laterally moved to facilitate the user to move the occupant in the wheelchair to a desired position. The utility model has the advantages that the component can be decomposed and bent to reduce the overall size, and the storage is convenient, which is a convenient, practical and economical invention.

According to the wheelchair structure device, it is mainly used to assist patients who are not convenient to walk. In recent years, wheelchairs have become a very common mobility aid due to the increase of barrier-free space. Today, the improvement of wheelchairs is usually only for occupants. The wheelchair is easy to travel. It does not provide the height and height of the wheelchair occupant to provide an adjustable height and height. It is suitable for all kinds of body users to meet the height of the wheelchair ride, and it can be done without any effort. It is convenient for the occupant not to get up and sit in the wheelchair cushion, and the occupant can easily move the rim seat to the designated area or space in parallel according to the demand.

Therefore, how to provide a wheelchair structure that meets the ride height of each occupant and how to easily move an occupant with difficulty in moving directly from the wheelchair cushion to a designated position is the place where the inventor of the present invention is committed to invention. Therefore, the inventor of this case has relied on his years of research and development experience in related fields to address the aforementioned shortcomings. In-depth discussion, and actively seek solutions according to the above needs, after a long period of hard research and multiple tests, finally completed the present invention.

The inventor of this case has been engaged in research in related fields for many years. He has been thinking and testing constantly how to meet the needs of consumers. He has tried his best to combine years of experience and repeated testing and experimentation and production. It is to solve the shortcomings of the practice and to enhance its unprecedented progress and practicality.

Accordingly, the main object of the present invention is to provide a wheelchair structure device that can arbitrarily move up and down and sway the occupant, and use the lifting structure to raise the occupant to a certain height, and then use the armrest structure together with the seat cushion to carry the occupant. The action of moving in parallel in parallel to achieve the purpose of facilitating the parallel movement of the occupant in the wheelchair to the desired position.

A secondary object of the present invention is to provide a wheelchair structure device that can arbitrarily move up and down and sway the occupant, and use the lifting structure to adjust the occupant's position to have the most appropriate seating height for comfort.

A further object of the present invention is to provide a wheelchair structure device that can arbitrarily move up and down and sway the occupant, and can reduce the overall size by using a bendable back structure and a lifting structure and a detachable rear wheel structure.

The position of the first armrest frame 302 is no longer resisted. At this time, the first armrest frame 302 and the second armrest frame 303 pivotally connected to the first armrest frame 302 by the pivot fixing member 306 can be horizontally arranged. Flattened, and the first armrest 302 and the second armrest 303 utilize the pivotal connection between the two New fastener 306, which can make the two sides are fixed in a horizontally flattened structure, in order to complete the wheelchair The occupant moves forward before moving laterally.

Finally, referring to FIG. 8 and FIG. 9 , when the first arm frame 302 and the second arm frame 303 are horizontally leveled and fixedly supported, the lifting structure 2 of the present invention can be used to adjust the height position. The user can pull the tab on the seat cushion 206 after being placed at the height to be moved to the final position (this is exemplified by the adjustment to the height position of the car seat shown in FIG. 9). 2061, moving the seat cushion 206 to the horizontally leveled first armrest frame 302 and the second armrest frame 303, and using the first armrest frame 302 and the sliding wheel 304 disposed on the outer surface of the second armrest frame 303 during the moving process The seat cushion 206 can be easily moved along with the occupant at a designated position. As shown in FIG. 10, the occupant in the wheelchair can be directly moved from the wheelchair to the vehicle 5, so that the occupant in the wheelchair can be conveniently used by the user. The primary purpose of moving to the desired location.

If the occupant is to be moved again to the wheelchair of the present invention (please refer to Figure 9), simply pull the occupant sitting on the seat cushion to the flattened handrail structure 3 of the present invention, using the The plurality of sliding wheels 304 on the armrest structure 3 can translate the occupant to the wheelchair of the present invention, and then the second armrest frame 303 is folded upward and flattened with the first armrest frame 302, and then the two sides are pulled. The slider head 3054 of the latch member 305 (refer to FIG. 1) is used to align the bump 3051 with the first arm frame 302 insertion hole 3021, and then the lever head 3054 is released, and the bump 3051 is caused by the elastic member. The cover 3053 fixed on the bump 3051 is driven by the return of 3052, and the bump 3051 is embedded in the first arm frame 302 fixing hole 3021, thereby fixing the support of the present invention. The hand structure 3, which in turn completes the occupant's translation into the wheelchair of the present invention.

Please refer to the wind 10 diagram. When the present invention needs to be placed in storage, the upper frame 202 can be first lowered to the lowest point by using the lifting structure 2 (ie, the seat cushion is lowered to the lowest point), and then the seat back structure 4 is The push rod 402 is pushed forward with force, so that the fastener 404 no longer fixes the position of the push rod 402 at the link 401, and the push rod 402 can be bent forward and placed flat above the seat cushion position, and finally pressed. In the block 1051, the wheel 104 can be completely removed after being connected to the round bar 105, so that the wheelchair structure of the present invention can be downsized and conveniently stored.

In summary, the wheelchair structure device of the present invention which can be arbitrarily raised and lowered and left and right translated by the inventor is designed by the inventor of the present invention, which not only has practical functions, simple structure, simple use, but also conforms to patents. In the case of the invention of the patent, the application for the law, the request for the examination of the member of the bureau, and the grant of the patent, is a pray.
