As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Furthermore, the technical features mentioned in the different embodiments of the utility model described below can be combined with each other as long as they do not conflict with each other.

Please refer to fig. 1 and fig. 2 together, which respectively show a schematic diagram and an exploded view of a U-tube linkage type shifting machine according to an embodiment of the present invention. The U-shaped tube linkage type displacement machine is mainly applied to assisting a patient to move. Specifically, the U-tube linkage type shifter comprises a bracket 100, a seat cushion assembly 200, a roller set 300 and a driving device 400. Wherein, the bracket 100 plays a role of integral support, the seat cushion assembly 200 provides hip support for a user, the roller set 300 plays a role of sliding, and the driving device 400 provides power.

Specifically, the stand 100 includes a handrail 110, a U-shaped bar 120, a support bar 130, and a base 140. The U-shaped rod 120 has an upward opening, the handrail 110 is disposed at an end of the U-shaped rod 120, the U-shaped rod 120 is slidably connected to the supporting rod 130, a bottom of the supporting rod 130 is fixedly connected to the base 140, and the supporting rod 130 functions to connect the U-shaped rod 120 and the base 140. Thus, the height of the seat cushion assembly 200 fixed on the U-shaped bar 120 can be adjusted by adjusting the U-shaped bar 120. More conveniently, the bottom of the U-shaped bar 120 is connected with a foot pedal 150, and the foot pedal 150 is rotatably connected with the U-shaped bar 120, it can be understood that the foot pedal 150 can be folded when being stored.

With respect to the seating pad assembly 200, it includes a guardrail 210 and a seat pad 220, the guardrail 210 being connected to the U-shaped bar 120 and the seat pad 220 being connected to the guardrail 210. The guardrail 210 serves as a safety guard for the user. Preferably, the guard rail 210 is rotatably coupled to the U-shaped bar 120. It will be appreciated that the guardrail 210 is used in conjunction with a seat cushion 220, the seat cushion 220 being pivotally connected to the guardrail 210. It is worth mentioning that the patient is inconvenient to turn or move on the seat, so the through hole 230 is formed inside the seat cushion 220, which is convenient for the patient to defecate.

More specifically, the seat cushion 220 includes a first cushion part 221 and a second cushion part 222, and the first cushion part 221 and the second cushion part 222 are rotatably connected to the guard rail 210, respectively. Thus, the edge of the first cushion portion 221 facing the second cushion portion 222 is recessed inward to form a first notch 231, and the edge of the second cushion portion 222 facing the first cushion portion 221 is recessed inward to form a second notch 232. The first and

second indentations

231 and 232 are also designed to facilitate defecation by the user. In this case, the guardrail 210 includes a first rail 211 and a second rail 212, and the first rail 211 and the second rail 212 are symmetrically disposed. In addition, in order to realize that the user can leave from the back, particularly when the U-shaped tube linkage type shifting machine is connected with the stair handrail, the user needs to leave the wheelchair from two directions, so the first rail 211 and the second rail 212 are respectively connected with the U-shaped rod 120 in a rotating way. The end of the first rail 211 away from the U-shaped bar 120 abuts against the end of the second rail 212 away from the U-shaped bar 120, or is provided with other locking devices, and the utility model is not limited thereto. It is understood that, for convenient storage, the first cushion portion 221 is rotatably connected to the first rail 211, and the second cushion portion 222 is rotatably connected to the second rail 212.

Regarding the roller set 300, which is mounted to the base 140, the roller set 300 includes a front wheel 310 and a rear wheel 320. It is understood that the configuration of the front and rear wheels 320 may be: the front wheels 310 are universal wheels and the rear wheels 320 are directional wheels or both the front wheels 310 and the rear wheels 320 are universal wheels.

The driving means 400 is used to drive the U-shaped bar 120 to slide up and down. The driving device 400 is typically a motor or the like. It should be noted that the conventional driving device 400 for raising the seat cushion assembly 200 is separately disposed on the two side supporting rods 130, but easily causes the problem that the first and second

seat cushion portions

221 and 222 are not lifted synchronously, but in the embodiment of the present invention, a U-shaped rod is used to connect the first and

second balustrades

211 and 212, respectively, to indirectly achieve the synchronous movement of the first and second

seat cushion portions

221 and 222. It is understood that the driving device 400 can also be used to drive the front wheel 310 to rotate, or the rear wheel 320 to rotate, or both the front and rear wheels 320 to rotate.

It should be noted that the description of the present invention and the accompanying drawings illustrate preferred embodiments of the present invention, but the present invention may be embodied in many different forms and is not limited to the embodiments described in the present specification, which are provided as additional limitations to the present invention and to provide a more thorough understanding of the present disclosure. Moreover, the above technical features are combined with each other to form various embodiments which are not listed above, and all the embodiments are regarded as the scope of the present invention described in the specification; further, modifications and variations will occur to those skilled in the art in light of the foregoing description, and it is intended to cover all such modifications and variations as fall within the true spirit and scope of the utility model as defined by the appended claims.
