Abstract

The invention discloses a deformable baby carriage, which comprises a handle bar, a pedal transmission mechanism, two parallel fixed wheels, a movable wheel and a baby seat, wherein the handle bar is connected with a frame; the backward-forward position of the movable wheel can be changed; the frame consists of a front frame 10 and foldable transition lever 31 and rear lever 32; a fixed position deformable locking device is fixed on the front frame 10; the transition lever 31 is hinged with the front frame 10 through the fixed position deformable locking device; a foldable locking device is arranged between the transition lever 31 and the rear lever 32; the baby seat is arranged on an extension part of the front frame; and the rear lever 32 is provided with a seat fixing device for clamping a seat stand rod 5. After simple change, the baby carriage can be conveniently changed into a pushing baby carriage and a riding baby carriage, so that the travel range of a user is expanded, and the interestingness and the convenience for traveling with a baby are increased.

Description

A kind of deformable perambulator

Affiliated technical field

The present invention relates to infant article, be specifically related to multifunctional baby carriage and make the field.

Background technology

There is the shortcoming of function singleness in perambulator in the market, generally all is the form that adopts doll carriage, and this brings multiple inconvenience to carrying baby's trip.Especially in the relative distance of going out place far away, merely hand push was both very long has an effort.Make in the time of more and become difficult to achieve whole family's pleasure trip on foot of band baby such as outing.

Summary of the invention

Shortcoming in view of prior art the objective of the invention is to design a kind of later-model deformable perambulator, makes it to overcome the shortcoming of prior art.The deformable perambulator that provides a kind of existing present perambulator function to have the cycling function again simultaneously; The user not only can carry the baby and rides like this; Also can be deformed into the perambulator of hand push; Can be used for father and mother and ride instead of walk and guarantee that baby safe is comfortably seated on the babychair, and in not time spent small size folding easily.

The objective of the invention is to realize through following means.

The invention discloses a kind of deformable perambulator; Comprise movable wheel and baby seat through vehicle frame bonded assembly handlebar, pedal transmission mechanism, two parallel fixing vehicle wheels, a convertible front and back position, vehicle frame is made up of side arm 10 and folding transition thick stick 31 and back thick stick 32; Location distortion blocking device is fixed on the side arm 10, and transition thick stick 31 forms through location distortion blocking device and side arm 10 and is hinged; Be provided with folding latching device between said transition thick stick 31 and the back thick stick 32; Baby seat is arranged on the extending part of side arm.Back thick stick 32 is provided with the vehicle seat anchor fitting that is used for clamping vehicle seat vertical rod 50.The present invention has enlarged user's the line range that goes out through becoming pushchair after the simple conversion easily and riding perambulator, has increased interest and the convenience of taking baby's trip.

Adopt structure of the present invention; Overcome the shortcoming of perambulator function singleness; A kind of deformable perambulator that not only has the present pushchair function while but also have the cycling function is provided, and the user not only can carry the baby and ride, and also can be deformed into the perambulator of hand push; Can be used for father and mother and ride instead of walk and guarantee that baby safe is comfortably seated on the babychair, not the time spent easily the small size folding put between storing or automobile trunk.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the present invention is described further.

Like Fig. 1 and Fig. 2 is respectively that the present invention constitutes the External view when riding perambulator and pushchair, and the serve as reasons perambulator of riding of Fig. 3 is deformed to the procedure structure scheme drawing of pushchair; The serve as reasons perambulator of riding of Fig. 4 is deformed to the structural representation that pushchair is near completion.

Can see that in conjunction with Fig. 1 to Fig. 4 the deformable perambulator comprises movable wheel and the baby seat through vehicle frame bonded assembly handlebar, pedal transmission mechanism, two parallel fixing vehicle wheels, a convertible front and back position.Vehicle frame is made up of side arm 10 and folding transition thick stick 31 and back thick stick 32.The folding latching device in location is fixed on the side arm 10, and transition thick stick 31 forms through distortion blocking device and side arm 10 and is hinged.As shown in Figure 5, location distortion blocking device location distortion blocking device comprises the U-shaped plate 20 that has chute 21 and positioning groove (22,23); The front end of said transition thick stick is provided with set pin 34 and the eccentric snap close 33 that is used for connecting with U-shaped plate positioning groove.Set pin 34 is slidably disposed in the chute 21, before and after distortion, is in two end positions (set pin 34 positions of expressing respectively like Fig. 1 and Fig. 2) of chute respectively.

Be provided with folding latching device between transition thick stick 31 and the back thick stick 32, this latching device is identical with the folding latching device of the folding bicycle of prior art, also adopts eccentric latching device with handles.Baby seat is arranged on the extending part of side arm; Back thick stick 32 is provided with the vehicle seat anchor fitting 37 that is used for clamping vehicle seat vertical rod 50.

When the perambulator of riding is deformed into pushchair, eccentric snap close 33 to be opened, the folding latching device snap close between thick stick of transition simultaneously 31 and the back thick stick 32 is opened, and vehicle seat vertical rod 50 is pressed in the arc folder 38 of vehicle seat anchor fitting 37.Lift transition thick stick 31 and make the set pin 34 of its front end move to highest point, will locate snap close 33 lockings, and will fold the locking of latching device snap close, promptly accomplish the operation that the perambulator of riding is deformed into pushchair along the chute 21 that is out of shape fixing and locking device U-shaped plate 20.

For guaranteeing as two of the track adjusting wheel interlocks of parallel fixing vehicle wheel when controlling, can adopt corresponding coordinated control mechanism, be employed in the present embodiment and be connected a gangbar 12 on the

front fork

13 and 14 of two wheels and be achieved.

For conversion and folding expediently, some can do folding position of handling, and all can handle in a conventional way like step tread, baby seat reinforced liner etc., do not give unnecessary details here.

Above embodiment is in order to help reader understanding's basic scheme of the present invention, and the protection domain of invention is not limited to such special statement and embodiment.Every making according to foregoing description variously possible be equal to replacement or change, and all is considered to belong to the protection domain that scheme of the present invention requires.
