Like Fig. 1 and shown in Figure 2; Should include a pad 21 and four articulated parts 22 by folding seat support 20; This pad 21 has a breach 211 in the position near this main wheel frame 10, this breach 211 is involutory with this cross bar 112, and this pad 21 is respectively equipped with two phases articulated part 22 side by side in the both sides of bottom; Should folding seat support 20 being pivoted with these two articulated parts 22 of a side is incorporated on this cross bar 112 of this bracing frame 11, and should folding seat support 20 between these bracing frame 11 these two vertical rods 111;

Should articulate the side that these two articulated parts 22 that are incorporated into this folding seat support 20 differ from this main wheel frame 10 of connection by folding wheel carrier 30; Should folding wheel carrier 30 include a mobile jib 31, a connecting rod 32 and a pair of wheels 33; This mobile jib 31 is inverted U-shaped and has a cross bar 311 and two vertical rods 312; This mobile jib 31 is hubbed at these two articulated parts 22 of these folding seat support 20 1 sides with this cross bar 311; Position in these two vertical rods, 312 contiguous these cross bars 311 is respectively equipped with a latch 313, and this latch 313 is fixed in these two vertical rods 312 with flexible member and can spurs front and back, laterally connects this connecting rod 32 in the position of these two vertical rod 312 adjacent bottom; In the bottom of these two vertical rods 312 difference johning knot should to wheels 33, this is to wheels 33 rotatable 360 degree.

Like Fig. 1 and shown in Figure 2; This installs the outside of inboard and this folding wheel carrier 30 that is incorporated into this main wheel frame 10 respectively to support bar 40; This support bar 40 has two ends, and an end articulates the inboard of this vertical rod 111 be incorporated into this bracing frame 11, in the slightly rectangular triangle of the other end and offer a chute 41; This chute 41 is elongated circular-arc and be respectively equipped with a blocking ditch 411 in two ends; The end that this support bar 40 has this blocking ditch 311 is articulated in this folding wheel carrier 30, and penetrates this chute 41 with these latch 313 correspondences of this folding wheel carrier 30, the track that the jackknife action that makes this folding wheel carrier 30 slides in this chute 41 along with this latch 313 and moving.

The embodiment of this utility model first preferred embodiment such as Fig. 3 are to shown in Figure 5:

As shown in Figure 3; During this utility model can be provided with, old people or sufferer be used for walk help and use, a user A can grip this handle 122, and this utility model is slowly carried out; If when carrying out excessive velocities; This user A can push this brake 13 slows down this action to wheels 15, conveniently this user walking of cooperation, and this breach 211 of this folding seat support 20 can prevent that this user A from raising both legs and can direct collision not fold seat support 20 to being somebody's turn to do when walking;

As shown in Figure 4, if when in the implementation process, feeling tired, then can sitting to stand on this folding seat support 20, this user A take a momentary rest, walk on again when treating antisecosis;

As shown in Figure 5; The take in mode of this utility model after using be with this this of folding wheel carrier 30 to latch 313 pull-ups after; With this to support bar 40 towards these main wheel frame 10 foldings, and should will draw in towards these main wheel frame 10 directions simultaneously by folding seat support 20, up to this latch 313 is slided in to each chute 41 of support bar 40 up to against to the position of each blocking ditch 411 time in this; This latch 313 promptly can be equipped in this blocking ditch 411; And this is restricted in to folding of support bar 40 action, when user not with this during to latch 313 pull-ups, this promptly can can't carry out jackknife action because of this latch 313 is equipped in this blocking ditch 411 to support bar 40; After accomplishing the folding action, this of this folding wheel carrier 30 position of wheels 33 is higher than this main wheel frame 10 this to wheels 15;

This utility model after the folding is owing to only independently stand on the ground with these wheels 15 of this main wheel frame 10; When towing, more be not vulnerable to the extruding of other wheels; And this utility model volume after the folding is less; And this is one of the forming to support bar 40, and structure is comparatively firm and folding is more or less freely, and is quite convenient and practical.

This utility model second preferred embodiment is as shown in Figure 6, and itself and first preferred embodiment are roughly identical, and difference is that this is to support bar 40 places:

These two latch 313 secure bond are in these two vertical rods 312; In this support bar 40 further is respectively equipped with a fixture 42, this fixture 42 includes a set bolt 421, a spring 422 and a pulling piece 423, and these set bolt 421 installings are incorporated into this support bar 40; This spring 422 is connected in this support bar 40 with an end; And connecting this pulling piece 423 with the other end, this pulling piece 423 can be sticked in this latch 313, when pulling this pulling piece 423 and separate with this latch 313; This support bar 40 can carry out the folding action along the track of this chute 41, and will be considerably convenient.

The above; It only is the preferred embodiment of this utility model; Be not that this utility model is done any pro forma restriction, any those skilled in the art are if in the scope that does not break away from technical characterictic that this utility model is carried; Utilize technology contents that this utility model discloses to do the local equivalent embodiment that changes or modify, all still belong in the scope of this utility model technical characterictic.
