ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of Invention
The invention relates to a handrail of a baby stroller, and more particularly to a combined handrail-and-frame structure of a baby stroller.
2. Related Art
Shown in FIG.
1
and
FIG. 2
are isometric views of the combined handrail-and-frame structures of a conventional baby stroller. As shown in FIG.
1
and
FIG. 2
, the conventional baby stroller includes a main body
11
and a clip
12
. Both an end of the main body
11
and the clip
12
itself appear a half-tube in shape. They are both pivotally connected to the frame
14
of the stroller to form a sleeve that is fitted around the circumference of the frame
14
. The other end of the main body
11
is connected to the handrail
13
. Moreover, a fin
121
positioned at a side and on the outer surface of the clip
12
is provided as a handle for pushing and pulling the slip with respect to the pivot for opening and positioning. The detaching and attaching the “main body
11
and clip
12
” from and to the frame need to open and close the fin
121
, thereby, it is very inconvenient.
But since the connection between the slip
12
and the frame
14
relies only on the shrink fitting by making use of the resilient nature of the slip
12
itself, the clip structure
12
can not ensure positive positioning action. Moreover, the protruded appearance of the fin
121
not only causes inconvenience but also shows bad aesthetic perception.
SUMMARY OF THE INVENTION
Therefore, it is one of the objectives of the invention to provide a combined handrail-and-frame structure that can positively and quickly detach the handrail from the frame and attach the handrail back to frame.
It is another objective of the invention to provide a combined handrail-and-frame structure that can positively position the handrail in horizontal and vertical directions.
It is yet another objective of the invention to provide a combined handrail-and-frame structure that can shows good aesthetic perception, and improve the quality level of the product.
In order to attain the foregoing and other objectives, a combined handrail-and-frame structure of a baby stroller of the invention includes an assembly and an engaging seat wherein the assembly includes an inner seat, a first fastener, a second fastener, a spring, and a housing. A hook with a lead inclined surface is provided in each of the first and second fasteners, and a convex push button is provided at the top of the second fastener. Moreover, a positioning head having an engaging fork is provided at an end of the assembly, and a spring installed in between the first and the second fasteners is also provided. In addition, a slit for clipping the engaging fork and an opening having a first and a second edge is provided in the engaging seat to be hooked up by the hooks for positioning the engaging fork in horizontal and vertical directions. When it comes to detaching, the push button is pressed to compress the spring, and the two hooks will be unlocked such that the assembly can be separated from the engaging seat.
