Detailed ways

Please refer to Figures 1 to 3, which show one embodiment of the foldable auxiliary rising chair of the present invention. The foldable auxiliary rising chair includes a body 10, a cushion frame 20, a cushion 30, a Pedal 40 and a link 50 . As a possible application, the auxiliary rising chair of the present invention can be applied to a lift chair for assisting a user in going up and down stairs, but the application of the present invention is not limited thereto.

The body 10 has a bottom 11, a body 12 and a chair back 13, the body 12 is connected between the bottom 11 and the chair back 13, and a pair of handrails 14 can also be provided on both sides of the chair back 13 for the upper limbs of the user to lean on and support. The free end of one of the armrests 14 can also be pivotally provided with a laterally extending blocking rod 15 to protect the user from falling from the front of the chair. For the purpose of easy folding, the armrest 14 may be pivotally connected to both sides of the seat back 13 .

The seat cushion frame 20 is connected to the main body 10. In this embodiment, one end of the seat cushion frame 20 is pivotally connected to the body 12 of the main body 10 and can pivot between a sitting position, a rising position and a folded position. The center of the seat cushion frame 20 can also be provided with a split groove.

The seat cushion 30 is connected to the seat cushion frame 20. In this embodiment, the front end of the seat cushion 30 is pivotally connected to the front end of the seat cushion frame 20 so as to pivot between a sitting position and a standing position. A spring 25 (as shown in FIG. 5 ) may also be provided between 20 and the seat cushion 30 .

The pedal 40 is connected to the body 10. In this embodiment, one end of the pedal 40 is pivotally connected to the bottom 11 of the body 10 and can pivot between a working position and a folded position. The pedal 40 also has a function extending in the front-rear direction. The chute 41.

Both ends of the linkage 50 are pivotally connected to the bottom of the seat cushion 30 and the pedal 40 respectively. Sliding between a working position and a folded position. The link 50 can be a linear actuator and has a telescopic rod 52 , the telescopic rod 52 passes through the slot of the seat cushion frame 20 and is pivotally connected to the bottom of the seat cushion 30 .

In the normal state of being available for riding, the chair has the state shown in Figures 1, 3, and 4. At this time, the seat cushion 30 and the seat cushion frame 20 are all in the seating position, and the slide block at the bottom end of the pedal 40 and the linkage 50 51 are all in the working position, and telescopic rod 52 is not stretched out.

When the user wants to get up, as shown in Figure 5, the linear actuator can be activated to make the telescopic rod 52 stretch out in a direction away from the pedal 40. At this time, the telescopic rod 52 can drive the seat cushion 30 toward the seat cushion frame 20 The upper pivot swings to the standing position, and the seat cushion frame 20 is driven by the seat cushion 30 and the spring 25, so it also pivots upward relative to the body 10 to the rising position, and the user's buttocks can be pushed up by the seat cushion 30, so that the upper body and thighs can With the knee as the fulcrum, it gradually transforms from a sitting posture upwards and forwards to a standing posture. The linear actuator assists in the process of rising up, reducing the burden on the user's large muscle groups, allowing the user to complete the rising movement with less effort.

When it is desired to fold the chair, as shown in Figure 6, the seat cushion frame 20 together with the seat cushion 30 can be lifted up and pivoted towards the main body 10 to the folded position. If it is not activated, the telescopic rod 52 will not extend, so the pedal 40 can be driven by the linkage 50 to pivot and fold towards the body 10, and the slider 51 at the bottom of the linkage 50 slides in the chute 41 at the same time At this time, both the pedal 40 and the sliding block 51 are located at the folded position, and the volume of the chair after being folded is greatly reduced, taking up less space.

When wanting to restore the chair to the unfolded state, the user can pivot the pedal 40 downward to the working position, and the seat cushion 30 and the seat cushion frame 20 are pulled by the linkage 50, so they also return to the seating position; To ensure that the slide block 51 of the link 50 can be reset to the working position smoothly, another return spring (not shown) can be further provided, and one end of the return spring is connected to the link 50 to provide the slide block 51. Elastic preload for return to working position. In other possible embodiments, the reset spring can also be omitted, and the user can manually reset the slider 51 . When the chair is fully unfolded, it returns to the configuration shown in Figures 1, 3 and 4.

Based on the above description, it can be seen that the foldable auxiliary rising chair of the present invention can assist the user to perform the standing up action, reduce the user's effort burden, and can assist the elderly or disabled users to get up, and the chair can be conveniently lifted when the chair is not in use. Folding or unfolding, it is obvious that the chair of the present invention can indeed meet various needs in use.

Although the present invention is illustrated with the above examples, it is not limited thereto. Other structural replacements or modifications that do not deviate from the spirit of the present invention should still fall within the scope of protection intended by the present invention.
