With reference to Figure 10, elongated transom 45b, there is the first connector 55b comprising the first hole or recess 57b and the second connector 59b comprising the second recess or hole 61b.First connector 55b is by being connected with handle in the recess 57b that the sphero-joint 49b of handle is contained in this first connector.
With reference to Figure 11, right wheel strut 23b also has the sphero-joint 63b extended inside it.Transom 45b is connected with pillar 23b by being contained in by the sphero-joint 63b of wheel strut in the second recess 61b on this transom.
Elongated transom 45a, 45b preferably rigidity substantially.Selectively, transom can have that some are flexible, but should enough rigidity to provide the action of push and pull on elongated handle member 33a, 33b.
Be connected with the ball-and-socket between pillar component 23b the three-dimensional motion provided between these components between the first end 55b and elongated handle member 33b of elongated transom 45b and at the second end 59b of elongated transom 45b.This adapts to the inside motion of the bottom of elongated handle member 33a, 33b, wherein, there is this motion when handle member 33a, 33b being moved downward in framing member 5a, 5b when the arc structure due to framing member 5a, 5b and handle member 33a, 33b.
Fig. 6 shows the cross section of framing member 5b.Framing member 5b has the chamber 65b of large main hollow, and this chamber 65b has the cross section 67b of substantially elliptical.The lower edge in this chamber comprises the elongate chamber 69b of the second separation, and this chamber 69b has the cross section 71b of roughly keyhole shape.The chamber 69b of this keyhole shape is open on the downside of it, thus the jut 47b on handle member 5b and sphero-joint 49b can be given prominence to downwards from it.
Figure 13 shows the telescopic construction of the elongated handle member 33b in framing member 5b.The cross section 67b in the chamber in the outer shape of handle member 33b and framing member 5b is complementary.Between handle member 33b and framing member 5b, be provided with space carry out sliding motion to make elongated handle member 33b relative to side frame member 5b.Liner can be set in the 67b of chamber to be provided for the slipping area of handle member.The lower edge of elongated handle member 33b has cavity 33b, and the bulbous portion of the keyhole shape of this cavity 33b and side frame member 5b is complementary.The push rod 51b of handle is positioned in the second chamber 69b of side frame member 5b, and jut 47b and sphero-joint 49b gives prominence to from the opening the pedestal of chamber 69b and side frame member 5b.
The use configuration that framework 1 can illustrate in fig 1 and 2, through the neutral configuration shown in Figure 16 and 17, to regulate between the complete folding configuration shown in Figure 19 and 20.When user wishes to carry out the framework of fold stroller from the use configuration shown in Fig. 1, they unclamp actuating device 39a, 39b, can carry out sliding extension motion to make elongated handle member 33a, 33b in side frame member 5a, 5b.Fig. 2 shows when perambulator is in framing member when using configuration and the position of connecting rod.In the configuration of Fig. 1, handle is in extended configuration.
Front vehicle wheel is resisted against in the solid object of such as wall and so on.Handle member 33a, 33b be pushed down enter into side frame member 5a, 5b time, the bottom of handle member promotes first end 55a, 55b of transom 45a, 45b downwards.
Because transom has fixing length, so the nose of the bottom of rear wheel pillar 23a, 23b towards framework 5 pulls forward by opposed end 59a, 59b of transom.
The half-lap configuration of framework can be seen in figure 16.Handle member 33a, 33b enter into side frame member 5a, the further motion of 5b makes handle member move to the contracted configuration shown in Figure 19.This makes first end 55a, 55b of transom 45a, 45b move downward relative to framing member 5a, 5b.Rear wheel support upright 23a, 23b inwardly pull towards framing member 5a, 5b by further, thus provide the complete folding configuration of the stroller frame as shown in Figure 19-11.
Because trailing wheel 31a, 35b are more spaced apart than front-wheel 13a, 13b greatlyr, so trailing wheel can be partly overlapping with front-wheel, from the folding configuration compact especially providing framework.Although do not illustrate in the drawings, can be arranged on framework or folded frame when removing from framework at passenger compartment 3.
Once framework is fully folded, frame lock can fix in complete folding configuration elongated handle member 33a, 33b to be clamped in side frame member 5a, 5b by again starting actuating device 39a, 39b by user.
