[specific embodiment]

At first please refer to shown in Fig. 1-2, perambulator one-handed performance folding structure embodiment of the present utility model, its seat of taking advantage of that is installed on collapsible perambulator skeleton is put on 10, the user must earlier the baby child be embraced behind perambulator, just can carry out the operation that folds of perambulator skeleton 2, return the vehicle to the garage and knock off with the accident of avoiding false touch and cause injury baby child; It comprises:

One folds skeleton 20, but comprising at least that foot rest before one 21, a rear leg 22, a handspike 23, a strut bar 24, a double-

action plate

25,26 on pipe 28 and one connecting rod articulate each other forms one and has and take advantage of the seat to put 10 and the skeleton structure that folds of interlock, the upper end of wherein preceding foot rest 21 articulates joint 27 with one and articulates with handspike 23, and the front end of this rear leg 22 and preceding foot rest 21 articulate, and this strut bar 24 is articulated between this handspike 23 and the rear leg 22; In addition, an end of this double-action plate 25 articulates with articulating joint 27, and the other end then is connected with connecting rod 26, and the other end of this connecting rod 26 then articulates with preceding foot rest 21, and this seat is managed 28 and is connected with rear leg 22 and seat position 10; Wherein be provided with blocking part 221 in this rear leg 22, in the middle of this enforcement, this blocking part 221 is a circular hole.

Please continue with reference to shown in the figure 2-5

One release gear 3, comprise a transverse tube 4, an operator 5, a pair of radius stay 6, elastic parts 7 and a pair of drive spindle 8; Wherein this transverse tube 4 is connected between the both sides double-action plate 25, and the central part of this cross bar 4 is provided with a pair of long slot bore that runs through 41; And this is to radius stay 6 transversely movable being installed in the transverse tube 4, wherein this end to radius stay 6 is a free end 61, this free end 61 by elastic parts 7 (in the middle of present embodiment, this elastic parts 7 is a compression spring) keep locating with blocking part 221 clips of rear leg 22, the other end of radius stay 6 is then fixing to drive spindle 8 with this, this drive spindle 8 movably is installed on this in the long slot bore 41, and protrudes from this long slot bore 41 outsides; This operator is 5 rotating being installed on this cross bar 4 in addition, this operator includes a pair of driving hypotenuse 51 (as shown in Figure 3) that is oblique relatively configuration at least to 5, and make this drive spindle 8 place a side of this driving hypotenuse 51, and make when this operator rotates 5, be able to drive spindle 8 be promoted to cross bar 4 central authorities by this driving hypotenuse 51, and then drive this to radius stay 6, make the blocking part 221 of the free end 61 disengaging rear legs of radius stay 6, (as shown in Figure 5) at this moment, this radius stay 6 is removed folding the restriction of skeleton 20, makes this skeleton be collapsible state.

As mentioned above, fold skeleton 20 when launching and being positioned running condition, the operator of this release gear 3 is the horizontal state to 5, and device has a cloth (not shown) on this release gear 3 in the middle of the present embodiment, makes baby child have more traveling comfort when taking advantage of; And when the operator desires folding skeleton 20, open a cloth earlier, operator is exposed 5, and then spur this operator 5 rotations, and this radius stay 6 of interlock is moved to transverse tube 4 central cross and break away from blocking part 221, it is removed folding the restriction of skeleton 20, reach collapsible purpose with this, and then, because the operator rotates in the restriction pull operation handgrip 5 that desire discharges 6 pairs of skeletons of this radius stay, so the operator is able to directly to spur this operator again and takes advantage of a situation 5 and will fold skeleton 20 pull-ups, make each pipe fitting rotation and be the state of folding, and because this folds after skeleton 20 folds, on this operator was positioned at 5, the operator also was able to mention 5 by this operator and folds skeleton 20 and move (as shown in Figure 6), with this utility model is reached and to avoid accident to fold skeleton, and can provide a kind of comfort feature splendid release gear.
