Refer to Fig. 1, perambulator safety locking system of the present invention includes hand-held mechanism 1, one-level control device 2 and Two-stage control device 3, front foot frame 4, rear foot tube 5, joint 6 and mounting 7, wherein above-mentioned mounting 7 is connected between above-mentioned front foot frame 4 and above-mentioned rear foot tube 5, when joint 6 is pivoted, by mounting 7 front foot frame 4 can be driven to be drawn close to rear foot tube 13.
Because the pattern of baby-carrier framework is numerous, though the present invention illustrates exemplified by only providing a simple skeleton, it is not limited thereto.It present invention can be suitably applied to the perambulator of its folding of various utilization joint controls.
Hand-held mechanism 1 is to connect a connecting rod top 1-1 and the connecting rod bottom 1-2 for the both sides that are placed in for a pair using connecting seat.Above-mentioned connecting seat includes an a upper connecting base 1-3 and lower connecting base 1-4, and using the lower end of the upper connecting base 1-3 connection connecting rods top 1-1, the lower connecting base 1-4 is connected to connecting rod bottom 1-2 upper end.Groove is respectively provided with above-mentioned upper connecting base 1-3 and lower connecting base 1-4.
The one-level control device 2 includes driving element, spring, keeper and the first flexible member.The driving element rotationally or is slidably installed on the 1-1 of connecting rod top, to control the pivot between the connecting rod top 1-1 and connecting rod bottom 1-2 and fixation.The spring is connected between driving element and the keeper.Slideably clip is within the groove of the upper connecting base 1-3 for the keeper, and first flexible member makes above-mentioned keeper be held between upper connecting base 1-3 and lower connecting base 1-4 to prevent connecting rod top 1-1 relative to connecting rod bottom 1-2 rotation.The driving element can directly or indirectly drive above-mentioned keeper via the spring, make keeper therefore depart from above-mentioned upper connecting base 1-3 groove, so that connecting rod top 1-1 can be rotated relative to connecting rod bottom 1-2.
Two-stage control device 3 is located between connecting rod top 1-1 and connecting rod bottom 1-2, including driving ring, moving part, clip element and the second flexible member；Second flexible member is connected between the clip element and hypozygal, and the clip element is allowed to keep clip on the blocking part of above-mentioned hypozygal by the elastic force of above-mentioned second flexible member；Above-mentioned moving part is connected between above-mentioned driving ring and above-mentioned clip element；The driving ring is connected with above-mentioned upper connecting base 1-3, above-mentioned driving ring can be rotated with above-mentioned connecting rod top 1-1, and above-mentioned driving ring drives the moving part, then drives the clip element via the moving part, the clip element is departed from the blocking part, the joint is recovered its pivot.
Among the present embodiment, joint 6 is formed by connecting by upper joint of the upper end provided with a blocking part and a hypozygal, and above-mentioned joint 6 is installed between hand-held mechanism 1 and baby-carrier framework, and above-mentioned joint 6 is used for controlling baby-carrier framework to enable expansion or folding；Above-mentioned hypozygal is connected to the upper end of front foot frame 4, and above-mentioned upper joint is connected to connecting rod bottom 1-2 lower end, and rear foot tube 5 is then connected to upper joint or is connected to connecting rod bottom 1-2.In addition, in the present embodiment, it is groove that blocking part, which is preferably,.
Preferably, also includes a head in upper connecting base 1-3 axle center, is connected with driving ring.Wherein driving ring connects moving part, and the other end of the moving part is connected with the clip element in joint 6.It is connected due to driving, with head, therefore when upper connecting base 1-3 is rotated with connecting rod top 1-1, above-mentioned head, driving ring will be driven to rotate, when above-mentioned driving ring is rotated connector can be made to affect clip element, so that above-mentioned clip element is with the blocking part for departing from hypozygal upper end, so that joint 6 is released, joint 6 is set to recover rotation.
The clip element in preferably, Two-stage control device 3 of the present invention can be uncinus, projection or shaft, the purpose is to make joint 6 not rotate to be caught in blocking part, baby-carrier framework is fixed after the expansion with this.When above-mentioned clip element departs from blocking part, above-mentioned joint 6 can recover to pivot, and then each rod member is pivotally drawn close, and realize the folding of perambulator.
Described one-level control device 2, the one-level control device 2 is relative to the rotation between the 1-2 of connecting rod bottom to controls connecting rod top 1-1.In the present embodiment, driving element is the sliding sleeve for being slidably located at above-mentioned connecting rod top 1-1 both sides, or is the driving element of one-hand operation.
Preferably, one-level control device 2 of the present invention also includes a pushing ring, the pushing ring is rotationally installed on adjacent with keeper in upper connecting base 1-3 groove and is connected with spring, the spring element driven turns pushing ring when pulling, above-mentioned pushing ring repels away from above-mentioned keeper upper connecting base 1-3 groove, connecting rod top 1-1 is set to be rotated relative to connecting rod bottom 1-2, so as to drive clip element indirectly and joint 6 is recovered its pivot.
Wherein the driving element of one-hand operation turns pushing ring via spring is pulled, and above-mentioned pushing ring also has the propulsion hypotenuse relative with keeper, above-mentioned propulsion hypotenuse repels away from above-mentioned keeper upper connecting base 1-3 groove, connecting rod top 1-1 is set to be rotated relative to connecting rod bottom 1-2, so as to drive above-mentioned clip element indirectly and the joint 6 is recovered its pivot.
The Two-stage control device 3 of the present invention, the Two-stage control device 3 is connected with connecting rod bottom 1-2 and interlocked with one-level control device 2, above-mentioned Two-stage control device 3 includes driving ring and moving part, and the connector, which can select scope, includes the things such as spring, plastic sheet or iron bar.Between above-mentioned moving part connection and above-mentioned driving ring and above-mentioned clip element.The driving ring, which is installed on, to be connected with head in lower connecting base 1-4 groove and is rotated with above-mentioned head, therefore when user makes connecting rod top 1-1 recover rotation using the driving element of one-hand operation, the driving ring will be rotated with head, so as to pull above-mentioned clip element by above-mentioned moving part, above-mentioned clip element is set to depart from the blocking part of hypozygal upper end so as to recover to pivot in joint 6.
When the 1-1 directions indicated according to arrow in connecting rod top are switched to a collapsed position, joint 6 is set to recover to rotate and carry out the folding of baby-carrier framework by Two-stage control device 3.
The present invention be using when rotating driving element and the connecting rod top 1-1 is reached predetermined angle, could folding baby-carrier framework again, user can not direct folding baby-carrier framework, safe effect is reached with this.
Above disclosed is only the preferred embodiments of the present invention, can not limit the interest field of the present invention, therefore the equivalent variations made according to scope of the present invention patent with this certainly, still belongs to the scope that the present invention is covered.
