The specific embodiment
As shown in Figures 1 and 2, the hand barrow that can stand after folding of the present utility model, have the front foot rest 2 of pair of armrests 1,, a rear leg 3, a hand push frame 4, a first connecting rod 5, a seat frame 6 and a lockout mechanism 7, wherein handrail 1 is located at the arranged on left and right sides of a handcart frame 10.
Front foot rest 2 connects respectively a front-wheel 21 in lower end, both sides, upper end and handrail 1 pivot joint; Rear leg 3 connects respectively a trailing wheel 31 in lower end, both sides, upper end and handrail 1 pivot joint and can which is provided with a pivot joint position 32 and a sliding part 33 with respect to front foot rest 2 pivotables, and make the sliding part 33 can be along the upper and lower slip of rear leg 3; For example sliding part 33 can be embodied as to general general sliding sleeve, be socketed on rear leg 3 and upper and lower slip, and by pivot joint position 32 as sliding part 33 mobile summit up, guarantee the stability of hand push frame 4 when launching use state 100.
Hand push frame 4 both sides are respectively equipped with one first centring point 41 and handrail 1 pivot joint, and are provided with one second centring point 42 and sliding part 33 pivot joints; First connecting rod 5 is with one end and 2 pivot joints of front foot rest, and the other end and sliding part 33 pivot joints, drive front foot rest 2 and hand push frame 4 towards rear leg 3 closings by making sliding part 33 down slidings.
Seat frame 6 comprises a leading portion 61, a back segment 62 and a second connecting rod 63, and wherein leading portion 61 is articulated between front foot rest 2 and back segment 62, and second connecting rod 63 is articulated between the pivot joint position 32 on back segment 62 and rear leg 3.As shown in Figure 4, the end of back segment 62 is articulated in one the 3rd centring point 64 between leading portion 61 two ends, make leading portion 61 have a bit of length can with back segment 62 lappings, make by this 3rd centring point 64 pivotable downwards, and the bearing surface that makes leading portion 61 and back segment 62 automatically form upon deployment seat takes out objective weight to take advantage of.
Lockout mechanism 7 is configurable takes up an official post where fold the position that process must relatively rotate or slide in handcart frame 10, as long as can make leading portion 61 and back segment 62 be pivoted relative to each other in when locking, or make sliding part 33 cannot down sliding and drive front foot rest 2 with hand push frame 4 towards rear leg 3 closings.
As shown in Figure 3, lockout mechanism 7 can be arranged between sliding part 33 and rear leg 3, comprises that one is subject to clip assembly 83 and a releasing mechanism 8 of spring-biased.Wherein be subject to the clip assembly 83 of spring-biased to be installed in sliding part 33, when locking, can, in order to clip rear leg 3, to stop sliding part 33 along the running that folds of rear leg 3 slips, thereby make handcart frame 10 be held in an expansion, use state 100.Releasing mechanism 8 and clip assembly 83 interlocks that are subject to spring-biased, in order to remove the lock-out state of the clip assembly 83 that is subject to spring-biased, thereby sliding part 33 can be slided along rear leg 3, make by this this handcart frame 10 be folded in a folding standing state 200.
The releasing mechanism 8 of the present embodiment can comprise an actuating assembly 81 and a linked component 82.Wherein actuating assembly 81 can be button, spanner, handle or sliding sleeve, is operatively installed on hand push frame 4; And linked component 82 can be steel cable, iron bar or any flexible component, in order to interlock in actuating assembly 81 and be subject between the clip assembly 83 of spring-biased.When actuating assembly 81 is operated or is driven, make to be subject to the clip assembly 83 of spring-biased move and finish its clip state to rear leg 3, make sliding part 33 therefore at seat frame 6, up be lifted and while folding, can slide and foot rest 2 and hand push frame 4 before folding simultaneously along rear leg 3, both are able to simultaneously towards rear leg 3 pivotable closings.
Lockout mechanism 7 is configurable in seat frame 6, makes leading portion 61 and back segment 62 cannot be pivoted relative to each other and carry out folding during locking, and state 100 is used in the expansion that makes by this handcart frame 10 be maintained as shown in Figures 1 and 2.As shown in Fig. 4 to Fig. 5, the lockout mechanism 7 of the present embodiment is disposed between leading portion 61 and back segment 62, by locking, makes the pivotable folding that cannot relatively make progress of leading portion 61 and back segment 62.Lockout mechanism 7 can comprise that one is subject to the hook assembly 71 of spring-biased, operatively be installed in the leading portion 61 of this seat frame 6, when lock-out state, in order to fasten releasedly the back segment 62 of seat frame 6, leading portion 61 and back segment 62 cannot upwards be drawn and carry and the folding that is pivoted relative to each other.
At the back segment 62 of the present embodiment, can establish one can clip position 65 for hook assembly 71 hooks that are subject to spring-biased.So-called position 65 that can clip can be embodied as a pin through back segment 62, back segment 62 be provided with slotted eye can be for the hook assembly 71 that is subject to spring-biased penetrates hook in pin.In addition, position 65 that can clip also can be embodied as recess to replace aforesaid pin, uses for being subject to hook assembly 71 hooks of spring-biased with locking seat frame 6.
When lockout mechanism 7 discharges, leading portion 61 and back segment 62 are pivoted relative to each other, second connecting rod 63 is also along pivot joint position 32 pivotables simultaneously, by leading portion 61, with respect to back segment 62 pivotables, amount to, make front foot rest 2 towards rear leg 3 pivotable closings, via first connecting rod 5 interlock sliding part 33 down slidings, make front foot rest 2 and hand push frame 4 be able to the while towards rear leg 3 pivotable closings simultaneously, finally make handcart frame 10 foldings become folding standing state 200 as shown in Figure 7.
Better one can connect a ribbon 72 between the arranged on left and right sides of seat frame 6, to facilitate the folding that upwards lifts seat frame 6 and start whole handcart frame 10.Be subject to hook assembly 71 and ribbon 72 interlocks of spring-biased, allow user rotated and the lock-out state of the mechanism 7 that unlocks by the hook assembly 71 of spring-biased by up pulling ribbon 72 to make.When user up pulls ribbon 72, by the lock-out state of mechanism 7 that unlocks simultaneously, and the 3rd centring point 64 is moved up thereupon, make seat frame 6 therefore present the folding of inverted V-shaped shape.
