Abstract
Abstract A foldable baby carriage has a pair of front legs and a pair of rear legs, with each rear leg being pivotally connected to the intermediate portion of the associated front leg and rearwardly downwardly extending therefrom. An angle bar is pivotally supported above the upper surface of each rear leg intermediate between the ends of the latter and has a pusher rod pivotally connected thereto. With the baby carriage in the opened state, the angle bar is substantially in line with the associated pusher rod portion. With the baby carriage in the closed state, the angle bar and the associated pusher rod portion are in bent relation to each other, thus reducing the vertical dimension of the baby carriage and at the same time reducing the distance between the front legs and between the rear legs and the distance between the front and rear legs, thereby establishing the folded state of the baby carriage.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
441 words
A baby carriage comprising; a pair of support leg pusher rod connecting rods (1) disposed to extend longitudinally, a pair of front legs (3) each pivotally connected (2) to the relatively forward portion of the associated support leg pusher rod connecting rod (1), a pair of rear legs (4) each pivotally connected (19) to the intermediate portion of the associated front leg (3) and rearwardly downwardly extending therefrom, a pair of pusher rod support angle bars (14) each pivotally connected at one end thereof (as at 16) to the intermediate portion of the associated rear leg (3) and adapted to be vertically turnable, a pair of pusher rod bodies (6) each pivotally connected at the lower end thereof (15) to the other end of the associated pusher rod support angle bar (14) and pivotally connected to the rear end of the associated support leg pusher rod connecting rod (1) at a pivot point (5) spaced a predetermined distance from the lower end of said pusher rod body, a pair of connecting rod turning members (23) each axially slidably fitted on the middle portion of the associated front leg (3), a pair of arms (26) each extending from said front legs (3), a front leg connecting rod (8) downwardly foldable at the middle thereof, pivotally connected at the opposite ends thereof (22) to said connecting rod turning members (23) and pivotally connected at positions spaced a predetermined distance from each end thereof to said arms (26), bar links (25) connected between said connecting rod turning members (23) and the front ends of said support leg pusher rod connecting rods (1), and a pusher rod connecting member (12) foldable at the middle thereof and pivotally supported at the opposite ends thereof by said pusher rod bodies (6), the arrangement being such that when said pusher rod support angle bars (14) are upwardly turned each around a pivot point (16) on one end thereof, the opened state of the baby carriage is established and that when said pusher rod connecting member (12) is folded and said pusher rod support angle bars (14) are turned in the opposite direction around said pivot points (16), said front legs (3), rear legs (4), support leg pusher rod connecting rods (1) and pusher rod bodies (6) are respectively turned toward each other while in response to the turning of said support leg connecting rods (1) said bar links (25) cause said connecting rod turning members (23) to slide upward while folding said front leg connecting rod (8), thereby establishing the folded state of the baby carriage in which the longitudinal, transverse and vertical dimensions thereof have been reduced.
Claim 2
Dependent Claim
441 words
A baby carriage comprising; a pair of support leg pusher rod connecting rods (1) disposed to extend longitudinally, a pair of front legs (3) each pivotally connected (2) to the relatively forward portion of the associated support leg pusher rod connecting rod (1), a pair of rear legs (4) each pivotally connected (19) to the intermediate portion of the associated front leg (3) and rearwardly downwardly extending therefrom, a pair of pusher rod support angle bars (14) each pivotally connected at one end thereof (as at 16) to the intermediate portion of the associated rear leg (3) and adapted to be vertically turnable, a pair of pusher rod bodies (6) each pivotally connected at the lower end thereof (15) to the other end of the associated pusher rod support angle bar (14) and pivotally connected to the rear end of the associated support leg pusher rod connecting rod (1) at a pivot point (5) spaced a predetermined distance from the lower end of said pusher rod body, a pair of connecting rod turning members (23) each axially slidably fitted on the middle portion of the associated front leg (3), a pair of arms (26) each extending from said front legs (3), a front leg connecting rod (8) downwardly foldable at the middle thereof, pivotally connected at the opposite ends thereof (22) to said connecting rod turning members (23) and pivotally connected at positions spaced a predetermined distance from each end thereof to said arms (26), bar links (25) connected between said connecting rod turning members (23) and the front ends of said support leg pusher rod connecting rods (1), and a pusher rod connecting member (12) foldable at the middle thereof and pivotally supported at the opposite ends thereof by said pusher rod bodies (6), the arrangement being such that when said pusher rod support angle bars (14) are upwardly turned each around a pivot point (16) on one end thereof, the opened state of the baby carriage is established and that when said pusher rod connecting member (12) is folded and said pusher rod support angle bars (14) are turned in the opposite direction around said pivot points (16), said front legs (3), rear legs (4), support leg pusher rod connecting rods (1) and pusher rod bodies (6) are respectively turned toward each other while in response to the turning of said support leg connecting rods (1) said bar links (25) cause said connecting rod turning members (23) to slide upward while folding said front leg connecting rod (8), thereby establishing the folded state of the baby carriage in which the longitudinal, transverse and vertical dimensions thereof have been reduced.
Claim 3
Dependent Claim

A baby carriage as set forth in claim 3, which further comprises a pair of tie rods (30) disposed in V form between the foldable portion of said first rear leg connecting rod (10) and pivot points (31) spaced a predetermined distance from and on opposite sides of the foldable portion of said second rear leg connecting rod (21).
Claim 6
Dependent Claim
59 words
A baby carriage as set forth in claim 2, which further comprises rods (91) connected between said first rear leg connecting rod (10) and said pusher rod support angle bars (14) and serving to operatively associate the folding movement of the first rear leg connecting rod (10) with the turning movement of the pusher rod support angle bars (14).
