A shifter 100 according to an embodiment of the present invention is described below with reference to fig. 1-12.

As shown in fig. 4 to 6, the shifter 100 according to the embodiment of the present invention includes: base member 1, seat support 2 and walking wheel 3. Base member 1 includes fender structure 11, pedal 12 and two landing legs 13, reserves human body space P at fender structure 11's rear on base member 1, and human body space P is located pedal 12's top, and two landing legs 13 set up in the bottom of base member 1, and pedal 12 can be dismantled or can open and shut or can set up on base member 1 with expanding. The seat 2 is detachably or openably or retractably connected to the base body 1, and the road wheels 3 are at least partially arranged on the legs 13, wherein the displacement machine 100 is switchable between a sitting position, a standing movement position, and a standing walking training position.

In the sitting position, the seat 2 is located above the two legs 13, and at least a portion of the seat 2 is located behind the human body space P, so that the patient can step on the pedals 12 and sit on the seat 2. In the standing movement position, the seat 2 is detached or opened or folded so that the rear side of the body space P is open and the patient can stand on the pedals 12. In the standing walker training position, the seat 2 is removed or opened or folded and the footrests 12 are removed or opened or folded so that the patient can stand on the floor between the two legs 13.

The base body 1 is a main structure of the shifter 100 for carrying and protecting the human body, and the human body space P is the position of the lower leg of the patient under most use conditions. Particularly, the introduction of the concept of the human body space P in the present embodiment is to describe the position relationship of each part structure of the shifter 100 relative to the human body space P in the case that the human body is in the sitting posture, the standing movement posture and the standing walking aid training posture, so as to reversely reflect the structural layout of each part of the shifter 100 and the position change of each structure when the posture changes, in order to take the human body space P as a reference object.

For example, in the case of normal use of a patient of normal size, when the patient sits on the seat 2, the feet of the patient step on the pedals 12, the lower legs of the patient are located in the body space P, the majority of the upper body of the patient is located above the seat 2, and the thighs of the patient extend from the body space P to above the seat 2; when a patient stands on the pedals 12, the lower leg of the patient is positioned in the human body space P, and most of the thigh and the upper body of the patient are positioned above the human body space P; furthermore, the patient can directly step on the ground while avoiding the seat 2, the pedals 12 and the legs 13, and the position of the patient on the shifter 100 is reduced relative to the position of the patient when stepping on the pedals 12, but the lower legs and even part of the thighs of the patient are located in the human body space P, and the upper body of the patient is mostly located above the human body space P.

Based on such design, when the shifting machine 100 needs to be used in a sitting posture and a standing moving posture, the shifting machine 100 can keep the center of gravity of the patient stable. Specifically, the base body 1 has a bottom structure in which the front and rear sides of the human body space P are in contact with the ground, for example, the front and rear sides of the human body space P are provided with traveling wheels 3 so that the center of gravity of the patient is between the front and rear traveling wheels 3 in both the sitting position and the standing position.

The front baffle structure 11 of the base body 1 can restrict the forward freedom degree of a patient, the safety of the patient in use is improved, and when the patient uses the shifting machine 100, a human body is located in a space behind the front baffle structure 11. The two legs 13 are located at the bottom of the base 1 so that when the footrests 12 are removed or opened or folded, the patient can stand on the floor through the space between the two legs 13. In some schemes below, the two support legs 13 can be opened and closed mutually, so that the form of the shifting machine 100 can be further changed, the two support legs 13 are opened when a patient stands on the ground, and the support legs 13 have small interference on the walking of the patient. In this arrangement, when the legs 13 are closed, the volume of the shifter 100 is reduced, which improves the flexibility of the shifter 100. When the supporting legs 13 are opened, the form of the shifter 100 can be changed, so that the shifter 100 is wider in application range and stronger in functionality.

Through setting up seat support 2, the pedal 13 that can dismantle or open and shut, the gesture of machine 100 that shifts can be switched over, and machine 100 that shifts can shift between the position gesture, the removal gesture of standing, the walking aid training gesture of standing to can improve the functional of machine 100 that shifts, improve machine 100's application scope that shifts. And the operation of switching the posture is simple, and the use is convenient.

By limiting the position relation of the human body space P on the shifter 100 relative to the front stop structure 11, the pedals 12 and the chair seat 2, a patient enters the shifter 100 from the rear side of the shifter 100, the body of the patient is forward when entering the shifter 100, and the body of the patient is still forward when the patient stands on the shifter 100 or sits down, so that the body of the patient does not need to rotate 180 degrees when entering the sitting down, and the use safety and the portability can be improved. And overall arrangement like this, can concentrate on the front side in human space with the front stop structure 12 of base member 1 and other unable dismantlement structures of machine of shifting 100, be convenient for on the one hand adjust the focus, avoid the car turnover, on the other hand makes the usage space of machine of shifting 100 great, and it is more convenient to shift the patient.
