The singlehanded seat obliquity structure of adjusting of a kind of perambulator
[technical field]
The utility model relates to the singlehanded seat obliquity structure of adjusting of a kind of perambulator.
[background technology]
Seat of baby's carriage portion the earliest is fixed on the skeleton, and the inclination angle of its back-rest can't be adjusted fully, and long-time sitting posture can not change arbitrarily, and the baby in the car is just very uncomfortable.Recent perambulator has allowed the Seat of baby's carriage back-rest can adjust the bevelled angle in order to adjust the angle of inclining and lying; As US Patent 4,077,641 patent cases, 4,344,649 patent cases, 5,018,754 patent cases, 5,240,265 patent cases, 5,454,584 patent cases etc. disclose the stroller configuration that various back-rests can be adjusted the angle of inclination.
The disclosed structure of aforementioned each patent case, though structure is different separately, a common problem points---its back-rest can be adjusted its angle of inclination though have, seat portion then still belongs to fixing can't the adjustment.And for example US Patent 4,072,318 patent cases, 4,892,327 patent cases and the 5th, 921, the content of patent cases such as 574, disclosed structure also only solves the adjustment problem of aforementioned back-rest, mainly is that back-rest and seat portion are fixed as one, and controls the angle of inclination at whole seat by the control mechanism of both sides; But these several disclosed structures of patent are some awkward problem also, such as when the operator when adjusting seat angle, must discharge the control mechanism that is positioned at perambulator skeleton both sides separately simultaneously with two hands, just adjusted the inclination at seat then.Aforesaid known control mechanism, the inconvenience of must two hands except when operation operating together, also have a danger---when the control mechanism of both sides all is released, whole seat loses clip suddenly, the virgin whole people of baby in the seat can turn over and the ground of dropping is quite dangerous with the seat most probably.

[specific embodiment]
At first see also shown in Fig. 1,2, the singlehanded seat obliquity structure embodiment that adjusts of perambulator of the present utility model, the operator only needs the singlehanded inclination that can control seat 3; Comprise a perambulator skeleton 10, a socket 2, a seat 3, a holding piece 4, an elastic parts 5 and a singlehanded adjusting mechanism 6 in the present embodiment.
Wherein perambulator skeleton 10 is a foldable type, can form a deployed condition and a folding state, and its medial surface is provided with a permanent seat 11.
Socket 2, it is this permanent seat 11 that is fixed in that can discharge disengaging, wherein extend connecting portion 21 in socket 2, connecting portion 21 is connected with seat 3, wherein the medial surface in connecting portion 21 is provided with clip tooth 100, because seat 3 is connected with socket 2, and these socket 2 releasable permanent seats 11 that are installed on this perambulator skeleton 10, selection is forward or towards the rear to (as shown in Figure 6) so the operator is complied with required replacing seat 3.
Seat 3 mainly is to orient seat 3 entire scope by a pair of U font pipe support tube 31 that slightly is, and weaves cotton cloth 30 by these support tube 31 suspensions, to constitute seat portion 32 and back-rest 33; Generally speaking, seat 3 constitute multiple formation kenel, as utilize integrally moulded etc.; In the middle of present embodiment,, be equiped with a rotation seat 34, these rotation seat 34 rotating connecting portions 21 that are articulated in this socket 2 in the both sides at this seat 3; Form in this rotation seat 34 and the relative clip tooth 100 of socket 2 connecting portions 21, and between this rotation seat 34 and connecting portion 21 inside, installing one is holding piece 4 movably, these holding piece 4 outer rims have locating piece 41, and the clip tooth 100 that makes holding piece 4 get while and this rotation seat 34 and connecting portion 21 forms the clips location; And the side in this holding piece 4 forms an ejection inclined-plane 42; Under normality, this holding piece 4 is by the ejection of an elastic parts 5 (being a compression spring in the middle of present embodiment), holding piece 4 is remained between rotation seat 34 and the connecting portion 21 (as shown in Figure 3), and make seat 3 form a fixing angle of inclination, take for baby child.
Singlehanded adjusting mechanism 6 comprises that remote controllers 61, moving part 62 and an actuator 63 form, and wherein these remote controllers 61 are that an end that is installed on this seat 3 (all can by upper end or lower end, in the middle of the present embodiment, be that remote controllers 61 are installed on upper end position, i.e. the top of back-rest 33), and these remote controllers 61 can have multiple kenel, as US Patent 4,846,494 patent cases, 4,906,017 patent case, 5,769,447 patent cases, 6,068,284 patent cases or the like structure; In the middle of present embodiment, these remote controllers 61 include a pedestal 64 and an operating handle 65, and wherein this pedestal 64 is ends that are fixed in seat 3, and operating handle 65 rotating being articulated on this pedestal 64.
The actuator 63 of this one hand adjusting mechanism 6 is installed on a side of this holding piece 4, and this actuator 63 has relative inclined-plane 631; This moving part 62 is to be connected between operating handle 65 and the actuator 63 in addition, and makes when rotating operation handle 65, is able to pulling actuator 63 rotations via moving part 62, and in the middle of present embodiment, this moving part 62 is the flexible cable wire of tool.
By above-mentioned member, under normality, this holding piece 4 remains in holding piece 4 between rotation seat 34 and the connecting portion 21 (as shown in Figure 3) by the ejection of an elastic parts 5, and makes seat 3 form a fixing angle of inclination, takes for baby child; When operator's desire is adjusted 3 inclination angles, seat, the singlehanded operating handle 65 (as shown in Figure 5) of pulling, this actuator 63 is rotated, when this actuator 63 rotates, ejection inclined-plane 42 by its relative inclined-plane 631 and holding piece 4, and then it is holding piece 4 is moving toward a thruster of rotation seat 34, and then disengaging connecting portion 21 (as shown in Figure 4), and the tumbler 34 at this seat 3 must be rotated with respect to connecting portion 21, this moment an operator grasps seat end of 3, do not cause seat 3 to have baby child's weight and rotate, the operator gets when turning to suitable angle voluntarily, decontrols this operating handle 65, by elastic parts 5, to between rotation seat 34 and the connecting portion 21,, and make seat 3 be positioned a constant tilt angle holding piece 4 ejection once again with the formation clip.
The connecting portion 21 of present embodiment can be directly fixed on the skeleton 10,3 inclination angles, adjustable bed rearrangement like this position, but non-exchange seat directions.
By illustrating of said structure embodiment, the utility model can make the operator only can adjust the angle of inclination at seat 3 with one-handed performance as can be known, can support seat 3 simultaneously again and take place to rotate improperly to avoid seat 3, has the effect of comfort feature and safety.
