Abstract
Abstract An operating mechanism disposed on a handle bar of a baby carriage for actuating locking mechanisms disposed at opposite ends of the handle bar and which locks the handle bar at a predetermined position or locks the baby carriage in a folded or an unfolded position. The handle bar has a hollow tubular construction and is bent in a U-shape or an inverted U-shape as viewed from its front. The operating mechanism includes a pair of slide members each of which is slidably disposed at the central portion of the handle bar, operating wires inserted into the handle bar, each of the operating wires having an upper end respectively retained by each of the slide members and a lower end attached to the locking mechanisms, and slide guide projections projecting from upper and lower sides of each of the slide members and an operating grip rotatably mounted on the surface of the handle bar, the operating grip having U-shaped guide grooves formed therein into which the slide guide projections are received. In this manner, the slide members can slide in the horizontal directions in the handle bar in response to rotation of the operating grips to thereby actuate the locking mechanisms.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
198 words
An operating mechanism disposed on a handle bar of a baby carriage for actuating locking mechanisms disposed at opposite ends of the handle bar which lock said handle bar at a predetermined position or lock the baby carriage in a folded or an unfolded position, said handle bar having a hollow tubular construction and being bent in a U-shape or an inverted U-shape as viewed from its front, said operating mechanism comprising: a pair of slide members each of which is slidably disposed at the central portion of said handle bar; operating wires inserted into said handle bar, each of said operating wires having an upper end respectively retained by each of said slide members and a lower end attached to said locking mechanisms; slide guide projections projecting from upper and lower sides of each of said slide members; and an operating grip rotatably mounted on the surface of said handle bar, said operating grip having U-shaped guide grooves formed therein into which said slide guide projections are received such that said slide members can slide in the horizontal directions in said handle bar in response to rotation of said operating grips to thereby actuate said locking mechanisms.
Claim 2
Dependent Claim
198 words
An operating mechanism disposed on a handle bar of a baby carriage for actuating locking mechanisms disposed at opposite ends of the handle bar which lock said handle bar at a predetermined position or lock the baby carriage in a folded or an unfolded position, said handle bar having a hollow tubular construction and being bent in a U-shape or an inverted U-shape as viewed from its front, said operating mechanism comprising: a pair of slide members each of which is slidably disposed at the central portion of said handle bar; operating wires inserted into said handle bar, each of said operating wires having an upper end respectively retained by each of said slide members and a lower end attached to said locking mechanisms; slide guide projections projecting from upper and lower sides of each of said slide members; and an operating grip rotatably mounted on the surface of said handle bar, said operating grip having U-shaped guide grooves formed therein into which said slide guide projections are received such that said slide members can slide in the horizontal directions in said handle bar in response to rotation of said operating grips to thereby actuate said locking mechanisms.
Claim 3
Dependent Claim
41 words
The operating mechanism of claim wherein each of said slide projections projecting from upper and lower sides of said slide members includes a single pin extending through each of said slide members and projecting from opposite upper and lower sides thereof.
Claim 4
Dependent Claim
45 words
The operating mechanism of claim 1 wherein each of said slide projections includes a pair of pins, one pin extending from the upper side of each of said slide members and the other pin extending from the lower side of each of said slide members.
Claim 5
Dependent Claim
34 words
The operating mechanism of claim wherein said handle bar includes horizontally and longitudinally extending grooves into which each of said guide projections are disposed to ensure that said guide members move horizontally without rotating.
Claim 6
Dependent Claim
23 words
The operating mechanism of claim wherein said U-shaped grooves are arranged such that top portions of the U-shapes are projected toward each other.
Claim 7
Dependent Claim
27 words
The operating mechanism of claim further comprising a spring for urging said slide members away from one another, said spring being disposed between said two slide members.
Claim 8
Dependent Claim
27 words
The operating mechanism of claim further comprising means for alternatively locking said operating grip such that said grip cannot be rotated or allowing said grip to rotate.
Claim 9
Dependent Claim
37 words
The operating mechanism of claim 7, wherein said operating means comprises a stopper slidably disposed in said handle bar and adjustable between a position engaged with said operating grip or a position disengaged from said operating grip.
Claim 10
Dependent Claim
18 words
The operating mechanism of claim wherein said operating grip include two semicircular members fixedly attached to one another.
Claim 11
Dependent Claim
23 words
The operating mechanism of claim wherein said handle bar has a pair of openings for allowing said slide members to be inserted therein.
