Abstract
Abstract Baby carriage having an X frame, the members of which are pivotally connected, and a U-shaped spring suspension. The lower ends of the X are slidably attached to the arms of the U. When the X is short and tall, the frame tensions the spring members of the suspension and projects above it. When the X is wide and short, the frame slides down on the arms of the U so that it may be stored at a minimum height.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
192 words
In a folding baby carriage comprising a frame and a spring suspension, said frame having members pivotally connected to each other in such a way that the height of said frame may be decreased and its length increased by swinging said members relative to each other, and said suspension means including spring members having upwardly projecting end portions, and means attaching one end of each frame member to one of said projecting end portions, said frame being dimensioned to tension said spring members when its length is reduced, but permit relaxation of said spring members when its length is at a maximum, the improvement comprising outwardly curved guide means integral with each end portion of said spring members, said attaching means comprising a ring mounted on said guide means for sliding movement between an upper spring-tensioning position occupied when the length of said frame is reduced and a lower position occupied when the length of said frame is at its maximum, in which said spring is permitted to relax and the top of said frame is lower with respect to said spring ends than when said ring is in its upper position.
Claim 2
Dependent Claim
192 words
In a folding baby carriage comprising a frame and a spring suspension, said frame having members pivotally connected to each other in such a way that the height of said frame may be decreased and its length increased by swinging said members relative to each other, and said suspension means including spring members having upwardly projecting end portions, and means attaching one end of each frame member to one of said projecting end portions, said frame being dimensioned to tension said spring members when its length is reduced, but permit relaxation of said spring members when its length is at a maximum, the improvement comprising outwardly curved guide means integral with each end portion of said spring members, said attaching means comprising a ring mounted on said guide means for sliding movement between an upper spring-tensioning position occupied when the length of said frame is reduced and a lower position occupied when the length of said frame is at its maximum, in which said spring is permitted to relax and the top of said frame is lower with respect to said spring ends than when said ring is in its upper position.
Claim 3
Dependent Claim
33 words
Carriage as claimed in claim 1 comprising means for locking said frame in a position at which its height is greater than its minimum height and in which it tensions said spring members.
Claim 4
Dependent Claim
40 words
Carriage as claimed in claim 1 in which each upwardly projecting end portion is first curved to define said guide means, and then bent to form an outwardly open hook which holds the corresponding ring when in its upper position.
Claim 5
Dependent Claim
49 words
Carriage as claimed in claim 1 in which each end portion of said spring is bent inwardly and downwardly to form a closed generally vertical loop constituting said guide, with the upper ends of said loop preventing the movement of said ring beyond its upper and lower positions respectively.
Claim 6
Dependent Claim
33 words
Carriage as claimed in claim 1 comprising yielding stop means carried by said guide means and positioned to resist sliding movement of said ring in one direction relative to the said guide means.
