Detailed description of the invention
As its basic framed structure, the Pushchair of one embodiment of the present invention comprises: pair of armrests; The a pair of forward foot in a step, its upper end is rotated and is connected freely handrail, and its lower end has front-wheel; The a pair of rear foot, its upper end is rotated and is connected freely handrail, and its lower end has trailing wheel; A pair of pipe link, the rear end part that connects freely handrail is rotated in its upper end, and its lower end is connected in the rear foot freely by carriage turns; Width link, the frame parts of connection left and right sides.The upper end of pipe link is taking the nearly top position of the point of connection of the rearward end of itself and handrail as terminal.Perambulator further comprises the handspike of changeable back side pushing state and opposite pushing state, is positioned at overlappingly the position in pipe link outside in the handspike of back side pushing state.
Below illustrate that embodiments of the present invention are as the illustration of perambulator with said frame structure, but the present invention is also applicable to the perambulator that forms the fixed type handspike that pipe link further extends upward from the rearward end of handrail.
Fig. 1～Fig. 4 is handrail 10 and the pipe link 20 being illustrated under the deployed condition of perambulator, the variation of handrail when Fig. 5 represents jackknife action and the position relationship of pipe link.Handrail 10 has upper wall 11 and pair of sidewalls 12, forms the state that the section of opening is contrary " U " word shape downwards.The upper end (not shown) of the forward foot in a step and the rear foot is rotated and is connected in freely this handrail 10.
Pipe link 20 is rotated and is connected in freely handrail 10 by adapter shaft 30, and its bottom is rotated and is connected in freely the rear foot by bracket (not shown).
Handrail 10 comprises armrest body and a pair of extension 13, wherein, described armrest body has the rear portion end face 11a with the upper wall 11 of the positive subtend of pipe link 20, and described extension 13 rearward extends to two sides of pipe link 20 from the rear end of the both sides of described armrest body.As shown in the figure, a pair of extension 13 of handrail 10 is rotated and is connected in freely pipe link 20 by adapter shaft 30.
Along with the jackknife action of perambulator, handrail 10 rotates centered by adapter shaft 30, and the intersecting angle of handrail 10 and pipe link 20 changes.Also it is identical in the time that perambulator does expansion action.
When Fig. 4 is illustrated in the jackknife action of perambulator with long and short dash line or while launching action, the arc track C that the rear portion end face 11a of handrail 10 draws centered by adapter shaft 30.If pipe link 20 is pipes of simple rectilinear form, in the half-way in the time that folding of baby moves or the half-way while launching action, the gap between rear portion end face 11a and the front of pipe link 20 of handrail 10 becomes maximum.In the time that this maximum clearance exceedes 5mm, the possibility that sandwiches finger or clothing improves.On the other hand, as long as the size of this maximum clearance is below 5mm, the possibility that sandwiches finger or clothing reduces.
In the perambulator of embodiments of the present invention, for the maximum clearance that reduces to form between the rear portion end face 11a of handrail 10 and the front of pipe link 20, in pipe link 20, in the time of jackknife action and the region 21 of the rear portion end face 11a subtend of handrail 10 form the shape that end surface 11a side is heaved backward.Specifically, the shape of heaving of heaving region 21 of pipe link 20 comprises and heaves straight line portion 21a and heave sloping portion 21b, wherein, described heave straight line portion 21a compare heave shape area more below region, on the extrusion position of handrail 10 sides, extend along axis direction straight line, described in heave sloping portion 21b and heave straight line portion 21a described in then and extend to the lower zone of pipe link.
By making pipe link 20 there is above-mentioned part 21a, the 21b of heaving, the size of the gap g forming between the rear portion end face 11a of the handrail 10 when can further reducing in the time of the jackknife action of perambulator or launching action and the front of pipe link 20.Preferably, select the shape of heaving of pipe link 20, the size that makes maximum clearance is below 5mm.Further preferably, adjust the shape of heaving of pipe link 20, the size that makes maximum clearance is below 3.5mm.
In the illustrated embodiment, pipe link 20 heave shape have be positioned at pipe link 20 fronts heave straight line portion 21a and heave sloping portion 21b, but this is an example.As other examples, also inflatable formation is stepped to heave part, and also inflatable formation is circular-arc.
In the above-described embodiment, make in pipe link, in the time of jackknife action or launch when action and the posterior end of handrail face to region form the shape of heaving towards rear portion end face side, the size in the gap forming between the rear portion end face of the handrail while thus, reducing folding of baby action or while launching action and the front of pipe link.As other embodiments of realizing identical action effect, also can form recess replacement formation at pipe link and heave shape.
Fig. 6 represents above-mentioned embodiment.The basic framed structure of Pushchair is identical with above-mentioned embodiment.In the illustrated embodiment, in pipe link 20, in the time that perambulator is deployed condition and the posterior end of handrail 10 in the face of to part form recess 25.In addition, as shown in the figure, in the time that perambulator is deployed condition, the rear portion end face 11a of handrail 10 is absorbed in the recess 25 of pipe link 20.In the present embodiment, be arranged in than recess 25 and more in fact play the effect of heaving shape of aforementioned embodiments in the region of top position, the size in the gap forming between the rear portion end face 11a of the handrail 10 therefore, can reduce folding of baby action time or while launching action and the front of pipe link 20.
As the variation of the embodiment of Fig. 6, also can form the hole that connects antetheca and replace recess 25.
Utilizability in industry
The present invention is applicable to the Pushchair that can effectively prevent that finger or clothing from sandwiching.
