Because the pattern of baby-carrier framework is numerous, though the present invention is only provided as a example by a simple skeleton illustrating, it is not limited thereto.Present invention can be suitably applied to the perambulator of its folding of various utilization joint controls.
Hand-held mechanism 1 is the connecting rod bottom 1-2 for connecting a connecting rod top 1-1 and 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 connects the lower end of connecting rod top 1-1 using the upper connecting base 1-3, and the lower connecting base 1-4 is connected to the upper end of connecting rod bottom 1-2.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.The keeper slidably clip within the groove of the upper connecting base 1-3, first flexible member above-mentioned keeper is held between upper connecting base 1-3 and lower connecting base 1-4 with 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 the groove of above-mentioned upper connecting base 1-3, 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, enable the clip element to depart from the blocking part, enable the joint to recover its pivot.
In the middle of the present embodiment, joint 6 is that the upper joint and a hypozygal for being provided with a blocking part by upper end is formed by connecting, 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 the expansion of baby-carrier framework enable or folding；Above-mentioned hypozygal is connected to the upper end of front foot frame 4, and above-mentioned upper joint is connected to the lower end of connecting rod bottom 1-2, and rear foot tube 5 is then connected to upper joint or is connected to connecting rod bottom 1-2.Additionally, in the present embodiment, blocking part is preferably groove.
Preferably, in the axle center of upper connecting base 1-3 a head and driving ring connection are also included.Wherein driving ring connects moving part, and the other end of the moving part is connected with the clip element in joint 6.Due to driving and head connection, therefore when upper connecting base 1-3 is rotated with connecting rod top 1-1, above-mentioned head, will order about driving ring rotation, 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 to rotate.
Preferably, the clip element in Two-stage control device 3 of the present invention can be uncinus, projection or shaft, and its objective is to snap in blocking part makes joint 6 to rotate, and 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 slidably located at the sliding sleeve of above-mentioned connecting rod top 1-1 both sides, or for 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 the groove of upper connecting base 1-3 and is connected with spring, spring element driven turns pushing ring when pulling, above-mentioned keeper is repelled away from above-mentioned pushing ring the groove of upper connecting base 1-3, connecting rod top 1-1 is rotated relative to connecting rod bottom 1-2, enable joint 6 to recover its pivot so as to drive clip element indirectly.
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 keeper is repelled away from above-mentioned propulsion hypotenuse the groove of upper connecting base 1-3, connecting rod top 1-1 is rotated relative to connecting rod bottom 1-2, enable the joint 6 to recover its pivot so as to drive above-mentioned clip element indirectly.
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 interlocks with one-level control device 2, above-mentioned Two-stage control device 3 includes driving ring and moving part, and the connector 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 is installed in the groove of lower connecting base 1-4 and is connected with head and rotates with above-mentioned head, therefore when user makes connecting rod top 1-1 recover to rotate 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 connecting rod top 1-1 is switched to a collapsed position according to the direction that arrow is indicated, makes joint 6 recover rotation by Two-stage control device 3 and carry out the folding of baby-carrier framework.
The present invention be using when rotating driving element and making connecting rod top 1-1 reach predetermined angle, could folding baby-carrier framework again, user cannot 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.
