ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates baby strollers, and more particularly to a simple folding-collapsible structure of baby stroller, which comprises two scats arranged to carry two babies at different elevations.
FIGS. from
1
through
3
show a folding-collapsible double-seat baby stroller according to the prior art. This structure of folding-collapsible double-seat baby stroller comprises two front wheel frames
10
, two rear wheel frames
20
, a top frame
30
, a bottom frame
40
a handle
50
, two folding handrails
60
, two front handrails
70
, and two links
80
. The top frame
30
and the bottom frame
40
are arranged in parallel. The links
80
are coupled between the top frame
30
and the bottom frame
40
. The top frame
30
has a rear side pivoted to the handle
50
. The bottom frame
40
has a front side pivoted to the front wheel frames
10
, and a rear side pivoted to the two distal ends of the handle
50
. The top frame
30
holds a front seat
100
and a rear seat
200
. The front handrails
70
are coupled between the front wheel frames
10
and the rear wheel frames
20
, and disposed at two opposite lateral sides of the front seat
100
. The folding handrails
60
arc coupled between the handle
50
and the top frame
30
, and disposed at two opposite lateral sides of the rear seat
200
. This structure of double-seat baby stroller is complicated. The installation of the front handrails
70
and the folding handrails
60
greatly increase the manufacturing cost of the baby stroller. Further, because the front seat
100
and the rear seat
200
are disposed at the same elevation at the top frame
30
, the baby sitting in the front seat will block the sight of the baby sitting in the rear seat.

It is one object of the present invention to provide a baby stroller, which is compact and folding collapsible. It is another object of the present invention to provide a baby stroller, which provides two seats for two babies. It is still another object of the present invention to provide a baby stroller, which has two seats arranged at different elevations so that the baby in the front seat does not block the sight of the baby in the rear seat.
