Abstract

Abstract This baby stroller utilizes an inexpensive, lightweight, portable, strong, foldable frame, for use in supporting a central seat portion. The frame assembly includes two pairs of transversely connected sidewall elements comprised of two overlapped cross-struts which are pivotally connected to one another, and which can be releasably secured into a stable, rigid X configuration by the use of a simple, inexpensive, one-piece latching brace. The latching brace is fixedly secured to one cross-strut at a distance from its pivotal connection to the other cross-strut, while the non-secured portion of each latching brace is designed to make a releasable, latching connection to and with the other cross-strut. When the latching brace is latched to the cross-strut to which it is not connected, each pair of cross-struts and their associated latching brace form a stable, rigid triangle. This three-piece triangular structure is easily releasable to a pivotable, foldable configuration.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 131 words
A foldable baby stroller frame including a pair of spaced apart sideframes, and means for transversely connecting said sideframes to provide a frame structure, wherein the improvement comprises, in combination: each sidewall being comprised substantially of a pair of pivotally connected overlapped cross-struts; and means for releasably latching said cross-struts into a braced, stable, rigid X configuration, said latching brace means including a head portion defining a through-opening for receiving and being fixedly attached to one said cross-strut, at a distance from its pivotal connection to the other said cross-strut, and a foot portion defining a gripping latching channel dimensioned to releasably receive, latch to, and grip the other said cross-strut to provide a rigid X configuration, whereby said latching brace means is substantially vertical when in latching and bracing use.
Claim 2
Dependent Claim 131 words
A foldable baby stroller frame including a pair of spaced apart sideframes, and means for transversely connecting said sideframes to provide a frame structure, wherein the improvement comprises, in combination: each sidewall being comprised substantially of a pair of pivotally connected overlapped cross-struts; and means for releasably latching said cross-struts into a braced, stable, rigid X configuration, said latching brace means including a head portion defining a through-opening for receiving and being fixedly attached to one said cross-strut, at a distance from its pivotal connection to the other said cross-strut, and a foot portion defining a gripping latching channel dimensioned to releasably receive, latch to, and grip the other said cross-strut to provide a rigid X configuration, whereby said latching brace means is substantially vertical when in latching and bracing use.
Claim 3
Dependent Claim 21 words
The invention as defined in claim 1 wherein said latching brace means is substantially vertical when in latching and bracing use.
Claim 4
Dependent Claim 18 words
The invention of claim 2 wherein each said latching brace means is substantially comprised of a single piece.
Claim 5
Dependent Claim 38 words
The invention as defined in claim 1, wherein one said cross-strut is located in said through-opening of said head portion, and said head portion of said latching brace means is riveted to said cross-strut located in said through-opening.
Claim 6
Dependent Claim 16 words
The invention as defined in claim 1, wherein said latching brace means is composed of plastic.
Claim 7
Dependent Claim 14 words
The invention as defined in claim 1, wherein said cross-struts are tubes or rods.
Claim 8
Dependent Claim 64 words
The invention as defined in claim 1, wherein said pair of pivotally connected cross-struts and said latching brace means, when latched together form a strong, stable triangle whereby said latching brace means form the vertical base of a triangle with the portions of said cross-struts to which it is connected, with the pivotal connection of said cross-struts providing the apex of the same triangle.
