Consult Fig. 1, Fig. 5, in the present embodiment, two groups of lockout mechanisms 3 are separately positioned on preceding foot lever 12, back foot lever 13, the side lever section 112 and pivot connecting seat 14 that vehicle frame 1 both sides are connected, and the structure of two groups of lockout mechanisms 3 is identical, below only with vehicle frame 1 wherein a lockout mechanism 3 of a side do explanation.

Consult Fig. 3 to Fig. 5, lockout mechanism 3 comprises a moving part 32 and a biased element 33.

Moving part 32 is arranged in the hollow shell portion 142 of pivot connecting seat 14, in the present embodiment, moving part 32 has the engagement section 325 that an epimere 321, a stage casing 322, the projection 324 and of a hypomere 323, between epimere 321 and stage casing 322 are formed on hypomere 323.Epimere 321 is inverted L shape and up exposes outside hollow shell portion 142 tops and be available for users to the application of force and up spur, stage casing 322 is provided with a pre-and post perforative hollow slots 327, biased element 33 is arranged in the hollow slots 327, and in the present embodiment, the hollow shell portion 142 of pivot connecting seat 14 comprises that also one is stretched through the fore-set 140 of the hollow slots 327 of moving part 32, this fore-set 140 can be by a connection piece (for example screw) to be fixed in hollow shell portion 142 another part structures 1423 on the local structure 1422, biased element 33 is a compression spring, its top is connected to fore-set 140, the bottom then is connected to the bottom of hollow slots 327, whereby, biased element 33 provides moving part 32 biasing force down, and can make actuated piece 21 parts can flexibly protrude handle section 111 by traction piece 31, projection 324 is stretched through the tube wall of sleeve pipe 141 and stretches in the side lever section 112 of driver's push rod 11 and is connected with the bottom 312 of traction piece 31, thereby moving part 32 can be subjected to the pulling of traction piece 31 with respect to pivot connecting seat 14 past superior displacements, in the present embodiment, engagement section 325 is hook arrangement and is formed on hypomere 323, and engagement section 325 is formed with a downward opening groove 326 that colludes, and engagement section 325 is by the perforate 1421 of the hollow shell portion 142 hollow shell portion 142 that stretches through out forward.

As shown in the above, moving part 32 except pulling that can be by traction piece 31 toward superior displacement, also be available for users to past superior displacement by directly up spurring epimere 321.

Consult Fig. 2, Fig. 5, when vehicle frame 1 is in a deployed condition, before the side lever section 112 of foot lever 12 and driver's push rod 11 all be the top backward and bottom heeling condition forward, and preceding foot lever 12 roughly is a straight line with

side lever section

112,13 of back foot levers are the top and bottom heeling condition backwards forward, at this moment, moving part 32 is owing to be subjected to biased element 33 biasing force down, thereby peritremes in foot lever 12 hole clippings 121 before the colluding groove 326 and down be hooked in of engagement section 325, make between the side lever section 112 of driver's push rod 11 and the preceding foot lever 12 locked and can't be pivoted relative to each other arbitrarily.

Consult Fig. 1, Fig. 6 to Fig. 8, when the user desires folding bicycle frame 1, by the pressing piece 222 of pushing the second road safety lock 22, remove the block effect of 222 pairs of actuated pieces 21 of pressing piece, again actuated piece 21 is moved towards 111, as shown in Figure 8, make the moving part 32 of lockout mechanism 3 be subjected to traction piece 31 pullings toward superior displacement, thereby allow the groove 326 that colludes of engagement section 325 up leave the tube wall that preceding foot lever 12 is positioned at hole clipping 121 root edges, just can remove the interference fit between driver's push rod 11 side lever sections 112 and the preceding foot lever 12, then, as shown in Figure 9 driver's push rod 11 is down pivoted forward, at this moment, the hollow shell portion 142 of pivot connecting seat 14 can be subjected to the drive of driver's push rod 11 and pivot away from preceding foot lever 12 backward, make the engagement section 325 of moving part 32 withdraw from the hole clipping 121 of forward foot in a step bar 12 backward, and driving foot lever 13 tops, back rotates toward backward shift and with respect to pivot connecting seat 14 with respect to preceding foot lever 12, and when driver's push rod 11 is continued to pivot, can be as shown in figure 10, down draw close with preceding foot lever 12, then foot lever 13 can be subjected to the drive of driver's push rod 11 and change into the top backward, bottom state forward, the driver's push rod 11 that down pivots and preceding foot lever 12 together closing in the top of foot lever 13 positions, about back, thereby with the down folding of whole vehicle frame 1, in addition, in the folding process, service plate 17 also can be subjected to interlock with service plate attaching parts 18 and down pivot and seat 4 is drawn close, so that vehicle frame 1 forms a collapse state.

When the user desires folding bicycle frame 1, also can be by moving part 32 epimeres 321 of pulling lockout mechanism 3, can allow the groove 326 that colludes of engagement section 325 up leave the tube wall that preceding foot lever 12 is positioned at hole clipping 121 root edges equally, and then the folding of carrying out vehicle frame 1 is operated, so implement in the aspect at other, latch-release mechanism 2 and traction piece 31 also can omit.

In addition, but in other enforcement aspect, latch-release mechanism 2 can not have the setting of the second road safety lock 22 yet, and certainly, many settings of the second road safety lock 22 can avoid being caused by inadvertent depression because of actuated piece 21 accident of vehicle frame 1 folding.And aforesaid two groups of lockout mechanisms 3 also can only be provided with wherein one group, and in other words, driver's push rod 11, preceding foot lever 12, back foot lever 13 that vehicle frame 1 also can have only a side wherein to be connected are provided with lockout mechanism 3 with pivot connecting seat 14.

In sum, the foldable perambulator of the utility model is by driver's push rod 11 of vehicle frame 1, preceding foot lever 12, back foot lever 13 provides the aspect of another kind of vehicle frame 1 structure with pivot connecting seat 14 ways of connecting, in addition, the respective outer side edges of latch-release mechanism 2 and lockout mechanism 3, allow the user when desiring the folding perambulator, only need one hand to push pressing piece 222 and actuated piece 21, just the locking of foot lever 12 before 3 pairs in the mechanism can unlock, then, again driver's push rod 11 is down pivoted forward, just can be with whole vehicle frame 1 folding, thereby have the advantage that makes the easier folding of perambulator.
