Abstract

Abstract A baby carriage handle support, including rotatable arms which fix the handle in upright position when the arms are aligned, uses an interlock which slides along the first arm until the second arm is inserted to the interlock support structure. The interlock support structure includes not only the usual end stop for the second arm, but also a channel projection at right angles to the stop which inserts to the channel of the second arm to provide a more positive locking relationship for the alignment of the two arms.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 144 words
An interlock support structure for aligning first and second, substantially flat, elongated channel members and locking said members in aligned relationship comprising a locking channel having a base in a plane generally parallel to the plane of said members, side flanges extending from said base defining therebetween a locking channel opening, a stop member substantially perpendicular to said base and terminating one end of said opening and a channel projection member generally parallel to and overlying said base and generally perpendicular to said stop member, all constructed and arranged such that said second member inserts into said opening with one of its ends abutting said stop member and said locking channel being slidable with respect to said first member, and said channel projection member received within the channel of said second channel member thereby improving the locking relationship and alignment of said channel members.
Claim 2
Dependent Claim 144 words
An interlock support structure for aligning first and second, substantially flat, elongated channel members and locking said members in aligned relationship comprising a locking channel having a base in a plane generally parallel to the plane of said members, side flanges extending from said base defining therebetween a locking channel opening, a stop member substantially perpendicular to said base and terminating one end of said opening and a channel projection member generally parallel to and overlying said base and generally perpendicular to said stop member, all constructed and arranged such that said second member inserts into said opening with one of its ends abutting said stop member and said locking channel being slidable with respect to said first member, and said channel projection member received within the channel of said second channel member thereby improving the locking relationship and alignment of said channel members.
Claim 3
Dependent Claim 30 words
The invention according to claim 1 wherein said slidable relationship of said locking channel and said first member is enabled by said locking channel flanges partially encircling said first member.
Claim 4
Dependent Claim 45 words
The invention according to claim 1 wherein said support structure further includes said members affixed to a carriage handle wherein the aligned relationship of said members supports said handle in an upright position and an angular relationship of said members enables collapse of said handle.
