Abstract
Abstract The conventional telescoping pusher handle for a baby carriage slides in housings attached to the carriage frame. Spring-loaded pins are mounted on one or both legs of the pusher handle. These snap into properly placed openings in housings when the handle is fully extended. To collapse the handle, one presses these pins inward with his fingers so that they disengage from the registering openings in the housings, allowing the handle to slide downward. The present release employs saddle-shaped triggers which can be rocked easily by the operator so that they depress the pins, thereby facilitating release of the pusher handle.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
117 words
In a foldable baby carriage of the type having a generally Ushaped pusher handle which is slidably mounted in tubular housings connected to the carriage frame and which has a springloaded pin mounted in the handle which is urged into an opening in the wall of said housing to lock said handle in its extended position, the improvement comprising a relatively rigid member engaging around said housing, said rigid member having a portion integral therewith overhanging said pin-receiving opening in said housing, means pivotally connecting said rigid member to said housing so that said portion thereof can be swung toward said opening so as to engage said pin projecting therethrough and push it back through said opening.
Claim 2
Dependent Claim
117 words
In a foldable baby carriage of the type having a generally Ushaped pusher handle which is slidably mounted in tubular housings connected to the carriage frame and which has a springloaded pin mounted in the handle which is urged into an opening in the wall of said housing to lock said handle in its extended position, the improvement comprising a relatively rigid member engaging around said housing, said rigid member having a portion integral therewith overhanging said pin-receiving opening in said housing, means pivotally connecting said rigid member to said housing so that said portion thereof can be swung toward said opening so as to engage said pin projecting therethrough and push it back through said opening.
Claim 3
Dependent Claim
80 words
A carriage as defined in claim 1 wherein said pin-receiving opening is elongated in a direction transverse to the longitudinal axis of said housing and said portion has a projection which is positioned directly opposite said opening and which is relatively straight along said transverse direction so that when said member is swung toward said opening, at least a part of said projection extends down into said opening so as to push said pin therein completely out of said opening.
Claim 4
Dependent Claim
48 words
A carriage as defined in claim 1 wherein the lower end of each said housing has an outwardly flared portion integral therewith which engages said pin when said handle is extended so as to gradually depress said pin to facilitate its sliding into said housing toward said opening.
Claim 5
Dependent Claim
49 words
A carriage as defined in claim 3 and further including a stop mounted near the lower end of at least one leg of said U-shaped handle for engaging said housing when said handle is pulled beyond its fully extended position so as to prevent undue extension of said handle.
Claim 6
Dependent Claim
14 words
A carriage as defined in claim 1 wherein said rigid member is generally U-shaped.
Claim 7
Dependent Claim
127 words
In a foldable baby carriage of the type having a generally U-shaped pusher handle which is slidably mounted in tubular housings connected to the carriage frame and which has a spring-loaded pin mounted in the handle which is urged into an opening in the wall of said housing to lock said handle in its extended position, the improvement comprising a relatively rigid, generally U-shaped strap engaging around said housing, said strap having a portion integral therewith overhanging said pin-receiving opening in said housing, means for pivotally connecting said strap to said housing so that said portion thereof can be swung toward said opening so as to engage said pin projecting therethrough and push it back through said opening so as to disengage said handle from said housing.
Claim 8
Dependent Claim
127 words
In a foldable baby carriage of the type having a generally U-shaped pusher handle which is slidably mounted in tubular housings connected to the carriage frame and which has a spring-loaded pin mounted in the handle which is urged into an opening in the wall of said housing to lock said handle in its extended position, the improvement comprising a relatively rigid, generally U-shaped strap engaging around said housing, said strap having a portion integral therewith overhanging said pin-receiving opening in said housing, means for pivotally connecting said strap to said housing so that said portion thereof can be swung toward said opening so as to engage said pin projecting therethrough and push it back through said opening so as to disengage said handle from said housing.
