Carrier unit and the binding that folds interlinked mechanism

Fold the binding of interlinked mechanism 80 and first carrier unit 10 and second carrier unit 20 referring now to Fig. 2 to Fig. 5 explanation.

At first, as shown in Figure 3, pass the pivot joint mouth 221 of left side the 4th support 22 of the pivoted hole 121 of right side first pole 12 of first carrier unit 10 and second carrier unit 20 and this of center rod 71 that fold interlinked mechanism 80 with the articulated part (not shown) of for example rivet to pivoted hole 711, so that right side first pole 12 is articulated in center rod 71 with left side the 4th support 22.Then, first through hole 821 of permanent seat 82 and the third through-hole 841 of continous action base 84 are passed in the lower end of center rod 71, and pass the fixed orifice 828 of permanent seat 82 and the fixed orifice 712 of center rod 71 with the articulated part (not shown) of for example rivet, so that permanent seat 82 is fixed in center rod 71, continous action base 84 can move with respect to center rod 71.

Then, elastic component 88 is inserted actuator lever 83, and make its two protuberance 881 outstanding from two apertures 832 of actuator lever 83 by the elastic restoring force of elastic component 88.Secondly the upper end of actuator lever 83 is inserted the centre hole (not shown) of handle 87, and pass the fixed orifice 871 of handle 87 and the fixed orifice 831 of actuator lever 83 with the articulated part (not shown) of for example rivet, and handle 87 is fixing with actuator lever 83.Then, as shown in Figure 1, right side second pole 13 is articulated in the place, below of center rod 71 with the right-hand member of right side the 3rd pole 14 and left side the 5th pole 23 and the left end of left side the 6th pole 24.

Then, pass second through hole 822 of permanent seat 82 from top to bottom with the lower end of actuator lever 83.When the protuberance 881 of elastic component 88 has just moved to second through hole 822 of permanent seat 82 downwards along with actuator lever 83, when two protuberances 881 of elastic component 88 are pressed in the actuator lever 83 by two shoulders 824 in second through hole 822 respectively, protuberance 881 is given prominence to outside the actuator lever 83 once again owing to be subjected to the elastic restoring force of elastic component 88, and is placed in the recess 825 of permanent seat 82.Then, the lower end of actuator lever 83 rotatably is connected in fourth hole 842 (not shown) of continous action base 84.

As shown in Figure 6A, protuberance 881 is subjected to shoulder 824 restriction, and swivelling pipe 83 can't move with respect to permanent seat 82, when protuberance 881 moves apart shoulder 824 and when overlapping with breach 827, swivelling pipe 83 just can relatively move mobile with permanent seat 82.Shown in Fig. 6 B, when swing handle 87 and interlock actuator lever 83 makes that when the breach 827 of protuberance 881 and permanent seat 82 overlapped, swivelling pipe 83 can move up with respect to permanent seat 82.

At last, as shown in Figure 3, pass this respectively to the pivoted hole 125 of pivoted hole 851 on these of trace 85 and right side first pole 12 and the pivoted hole 225 of left side the 4th pole 22, so that this is articulated in right side first pole 12 and left side the 4th pole 22 respectively to trace 85 upper ends with the articulated part (not shown) of for example rivet.Then, these these following pivoted holes 852 to trace 85 are inserted these pivot connected slots 843 of continous action base 84 left and right sides respectively, and pass the pivoted hole 844 of continous action base 84 and the following pivoted hole 852 of trace 85 cooresponding with it with the articulated part (not shown) of for example rivet, so that this is articulated in continous action base 84 to trace 85.

By above binding, finish the double seat infant car frame of the utility model preferred embodiment.

Vehicle frame fold operation

When desiring to fold vehicle frame (this moment, vehicle frame was in deployed condition shown in Figure 1), swing handle 87 so that the protuberance 881 of elastic component 88 align in the vertical (shown in Fig. 6 B) with the breach 827 of permanent seat 82 and then upwards draw, continous action base 84 moves up in company with handle 87 and actuator lever 83, and this is also upwards passed trace 85 upper ends simultaneously.As shown in Figures 7 and 8, along with this upwards passing to trace 85 upper ends, the right-hand member of the left end of right side first pole 12 and left side the 4th support 22 upwards pivots with respect to center rod 71, and then the guide rod 255 that makes first guide rod 155 and second that folds part 15 fold part 25 moves up with respect to center rod 71 simultaneously, first slide 153 and second that folds part 15 folds the slide 253 of part 25 respectively along guide rod 155,255 move down, and first mobile jib 11 and second mobile jib 21 respectively with respect to guide rod 155,255 move down, therefore first carrier unit 10 and second carrier unit 20 pivot linkedly and fold, at this moment first mobile jib 11, the center rod 71 and second mobile jib 21 can be close mutually.When this trace 85 is parallel to each other and first mobile jib 11, center rod 71 and second mobile jib 21 mutually near the time, finish folding of vehicle frame.

The expansion operation of vehicle frame

When desire is launched vehicle frame (this moment, vehicle frame was in collapse state shown in Figure 8), can one hand steered center rod 71, push handle 87 downwards with another hand, this moment, actuator lever 83 moved down along permanent seat 82, by the inclined-plane on the shoulder 824 of permanent seat 82, continue to move down after making the protuberance 881 of elastic component 88 press in the actuator lever 83, up to protuberance 881 by after the shoulder 824, by the outstanding once again actuator lever 83 of elastic restoring force and till being placed in the recess 825 of permanent seat 82 (as shown in Figure 5).The actuator lever 83 that folds interlinked mechanism 80 simultaneously moves down with respect to center rod 71, first carrier unit 10 and second carrier unit 20 launch simultaneously, first mobile jib 11, center rod 71 and second mobile jib 21 mutually away from, and then make vehicle frame remain on as shown in Figure 1 deployed condition.

In this embodiment, permanent seat 82, actuator lever 83, handle 87 and elastic component 88 formation one that fold in the interlinked mechanism fold assembly.By the rotation of handle 87, this folds assembly and can move between a latched position and a unlocking position.When being positioned at latched position, continous action base 84 can't at random move with respect to center rod 71, makes vehicle frame maintain deployed condition.When being positioned at unlocking position, continous action base 84 can move with respect to center rod 71, and then drive trace 85 moves.In other embodiments, fold assembly and also can use other prior art, as long as can reach the purpose that makes continous action base 84 location.And in another embodiment, trace 85 not necessarily will connect first pole 12 and the 4th pole 22, also can connect the 3rd pole 14 and the 6th pole 24, as long as after folding the assembly release the lock, move on the pulling continous action base 84, drive two sidecar frame poles simultaneously and move, can reach the object of the invention towards stowed position.

But above-described only is preferred embodiment of the present utility model, when not limiting the scope that the utility model is implemented with this, be that all simple equivalent of being done according to the utility model claim and utility model description change and modify, all should still belong in the scope that the utility model patent contains.
