Detailed ways

Referring to Fig. 2 to Fig. 3C, the wheelchair device 2 with interlocking mechanism of the present invention comprises a wheelchair body 21, a pedal device 22, two brake devices 23, two pedal adjustment devices 24, two brake adjustment devices 25 and a connecting rod Structure 26. Pedal device 22 is arranged on the bottom of wheelchair body 21 front, and brake device 23 is arranged on the left and right sides of wheelchair body 21 respectively, and pedal adjustment device 24 is arranged on wheelchair body 21 and connects pedal device 22, and brake adjustment device 25 is also arranged on The left and right sides of the wheelchair body 21 are respectively connected with the braking device 23 on the same side. The connecting rod structure 26 is arranged on one side of the wheelchair body 21 and connected to the pedal adjustment device 24 and the brake adjustment device 25 respectively.

The connecting rod structure 26 is connected with the pedal adjusting device 24 with a round tubular outer tube 27, and the connecting rod structure 26 is connected with the brake adjusting device 25 with an inner tube 28 pierced in the outer tube 27, and the two ends of the inner tube 28 are respectively A brake adjustment device 25 is connected. The connecting rod structure 26 has a pulling part 261, a fixed part 262 and a linking part 263. One end is pivotally connected, and the other end of the linkage member 263 is connected to the outer tube 27. By pulling the trigger member 261, it rotates around the fulcrum 211 pivotally fixed to the wheelchair body 21, thereby driving the stopper 262 to stop. The part 2621 resists the linkage 263 and drives the linkage 263 to rotate, and then the outer tube 27 drives the pedal adjustment device 24 to rotate, so that the pedal device 22 changes from the storage state to the use state. Moreover, when the pedal device 22 is in use, if you want to directly store the pedal device 22 by applying force downward to the pedal device 22, the connecting part 263 will not be able to move upward because the fixed part 2621 is against the connecting part 263. Turn over, thereby can firmly fix the position of pedal device 22, so then can avoid causing danger. In order to change the pedal device 22 from the use state to the storage state, it is also necessary to pull the trigger part 261 to drive the fixed part 262 to rotate, so that the fixed part 2621 no longer withstands the linkage part 263, and drives the linkage The member 263 rotates, so that the connecting member 263 rotates the outer tube 27 to drive the pedal adjustment device 24 to convert the pedal device 22 from the use state to the storage state. The linkage member 263 of the connecting rod structure 26 is also connected with the inner tube 28 to drive the brake adjustment device 25 , and then make the brake device 23 act to achieve the braking effect. When the puller 261 is pulled to drive the linkage 263 to rotate the outer tube 27 to control the pedal device 22, the linkage 263 simultaneously rotates the inner tube 28 to control the braking device 23 to perform braking.

As shown in Figure 4, with the help of the function of the connecting rod structure 26, when the user 3 sits on the wheelchair device 2, if he wants to leave the wheelchair device 2, he only needs to sit and manually pull the brake adjustment device 25 and the pedal adjustment device 24. The connecting rod structure 26 is used to stop the wheelchair device 2 to avoid the movement of the wheelchair device 2; This allows the user 3 to get out of the wheelchair device 2 without the assistance of others, and also avoids dizziness or other accidents caused by bending over to pull the pedal device as in conventional wheelchair devices. occur.

Please refer to Fig. 5, in this embodiment, the pedal adjustment device 24 and the brake adjustment device 25 are respectively controlled by two identical connecting rod structures 26, and the connecting rod structures 26 are respectively arranged on both sides of the wheelchair body 21 and connected to the outer tube respectively 27 and inner pipe 28. Pull the puller 261 of the connecting rod structure 26 connected to the outer tube 27, so that the puller 261 rotates with the fulcrum 211 as the center of a circle and then drives the fixed piece 262 to rotate to withstand the linkage 263, so that the linkage 263 can follow the The triggering member 261 rotates together, and at the same time drives the pedal adjustment device 24, thereby making the pedal device 22 change from the storage state to the use state or from the use state to the storage state. In addition, by pulling the puller 261 of the connecting rod structure 26 connected to the inner tube 28, the inner tube 28 can be controlled to rotate by the same connecting rod action, and the braking device 23 can be driven to produce a braking effect.

As shown in Figure 6, the wheelchair device 2 of the present invention can also be connected to the pedal adjustment device 24 and the brake adjustment device 25 with only one round tube 29, and can also be controlled simultaneously with the linkage structure 26 through the function of the linkage structure 26. The inner tube 28 has the same effect as the outer tube 27 .

As shown in Figure 7, the wheelchair device 2 with interlocking mechanism of the present invention can also have a pair of pedal devices 22 arranged on the front lower part of the wheelchair body 21, and each of the pedal devices 22 is connected to a pedal device arranged on the wheelchair body 21. Adjusting device 24, this pedal adjusting device 24 is connected to round pipe 29 (or outer pipe 27) simultaneously, drives round pipe 29 (or outer pipe 27) to rotate by connecting rod structure 26, so that pedal adjusting device 24 follows round pipe 29 (or the outer pipe 27) rotates and then controls the pedal device 22 to change from the storage state to the use state or from the use state to the storage state.

The above description is only a preferred feasible embodiment of the present invention, and does not limit the scope of the present invention. Therefore, all equivalent technical changes made by using the description of the present invention and the contents of the accompanying drawings are included in the protection of the claims of the present invention.
