Abstract

Abstract A connector for a child vehicle, such as a stroller or carriage, for connecting sub-assemblies to the tubular frame of the vehicles. The sub-assemblies each have a connecting portion for close mating fit with associated connecting free end portions of the tubular frame. The mated portions are interconnected by a spring-biased connecting member which is provided in one of the mated connecting portions or connecting free end portions, and has a lock element locatable in a through bore in the other portion. The lock element is retractable inwardly of the through bore for disconnecting the mated portions.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 260 words
A connector for a child stroller, carriage or similar child vehicle for connecting sub-assemblies thereto for easy removal of said sub-assemblies by a user person and wherein said vehicle has a tubular frame to which said sub-assemblies are each secured through a respective one of said connectors, said sub-assemblies each having a connecting portion for close mating fit with connecting free end portions of said tubular frame, said mated portions being interconnected by a spring-biased connecting member provided in one of said mated connecting portions or connecting free end portions, and having a lock element automatically locatable in a through bore in the other portion, said lock element having means for retracting same inwardly of said through bore for disconnecting said mated portions whereby one or more of said sub-assemblies may be disconnected and removed from said tubular frame without the use of special tools, said spring member being a V-shaped leaf spring member formed with a bottom leaf portion and a top lock element carrying portion, said spring being located in compression in an enclosure adjacent said mating wall section having said hole with said lock element aligned with said hole, said spring being retained in tight friction fit in said enclosure by compression force exerted on enclosure walls by said leaf spring, said bottom leaf portion having an inwardly bent engageable free end section extending toward said top lock element carrying portion and elevated above an inner surface of said enclosure, said engageable end section permitting ease of locating and removal of said spring member in said enclosure.
Claim 2
Dependent Claim 260 words
A connector for a child stroller, carriage or similar child vehicle for connecting sub-assemblies thereto for easy removal of said sub-assemblies by a user person and wherein said vehicle has a tubular frame to which said sub-assemblies are each secured through a respective one of said connectors, said sub-assemblies each having a connecting portion for close mating fit with connecting free end portions of said tubular frame, said mated portions being interconnected by a spring-biased connecting member provided in one of said mated connecting portions or connecting free end portions, and having a lock element automatically locatable in a through bore in the other portion, said lock element having means for retracting same inwardly of said through bore for disconnecting said mated portions whereby one or more of said sub-assemblies may be disconnected and removed from said tubular frame without the use of special tools, said spring member being a V-shaped leaf spring member formed with a bottom leaf portion and a top lock element carrying portion, said spring being located in compression in an enclosure adjacent said mating wall section having said hole with said lock element aligned with said hole, said spring being retained in tight friction fit in said enclosure by compression force exerted on enclosure walls by said leaf spring, said bottom leaf portion having an inwardly bent engageable free end section extending toward said top lock element carrying portion and elevated above an inner surface of said enclosure, said engageable end section permitting ease of locating and removal of said spring member in said enclosure.
Claim 3
Dependent Claim 113 words
A connector as claimed in claim 1 wherein said connecting member is a spring member having said lock element secured thereto, said element extending through a hole in a mating wall section of either of said mated portions, said lock element being a locking pin retractable inwardly of said mating wall section by pressure applied at a pin free end thereof which is aligned with said tthrough bore so that said lock element automatically enters said through bore to lock said mated portions, said means for retracting same being constituted by said free end whereby upon application of axial pressure on said free end said locking pin retracts inwardly of said through bore.
Claim 4
Dependent Claim 30 words
A connector as claimed in claim 2 wherein said locking pin free end has a tapered circumferential edge, said pressure applied at said pin free end being a finger pressure.
Claim 5
Dependent Claim 23 words
A connector as claimed in claim 1 wherein said enclosure is a hollow tubular end section of said frame connecting free end portions.
Claim 6
Dependent Claim 48 words
A connector as claimed in claim 4 wherein said sub-assemblies connecting portion is a tubular portion having a cavity in a free end thereof for receiving said tubular end section in close sliding fit therein, said through bore being provided in a side wall of said tubular portion.
Claim 7
Dependent Claim 35 words
A connector as claimed in claim 5 wherein said cavity has a base wall, said tubular end section having an end thereof abutting said base wall with said lock element aligned with said through bore.
Claim 8
Dependent Claim 43 words
A connector as claimed in claim 2 wherein said through bore is provided with a circumferential flange extending outwardly of an outside wall thereabout, said flange extending outwardly a distance at least equal to said free end of said locking pin located therein.
Claim 9
Dependent Claim 20 words
A connector as claimed in claim 1 wherein said enclosure is a hollow tubular connecting portion of a wheel sub-assembly.
