Description
FIELD OF THE INVENTION
[0001] The present invention relates to a framework folding
mechanism of baby swing, and more particularly, to a framework
folding mechanism of baby swing that the user is capable of
directly pulling a connecting base-plate to start the folding
action of the framework to make the front and rear supporting
stands approach each other for folding.
DESCRIPTION OF THE PRIOR ART
[0002] The baby swing is an article for the parents to soothe baby
by playing with the baby or regularly swaying to make the baby fall
asleep. The function of the baby swing is similar to the baby
rocking chair that is classified into two types of product on the
market, i.e. the manual one and the electrical one. Take the U.S.
Pat. No. 6,319,138 and the Taiwan Patent No. 457,907 for examples,
both of the patents use electrical one to drive the baby rocking
chair for saving the operator's labor such that his/her nands can
do something else. The electrical baby rocking chair mainly
includes a supporting frame, two swaying arms, a seat, and a
transmitting mechanism. Among them, the transmitting mechanism
drives the swaying arms to sway while the swaying arms are
connected between the transmitting mechanism and the seat. The seat
is driven indirectly to sway back-and-forth by the transmitting
mechanism.
[0003] Since the above-mentioned baby rocking chairs is bulky and
not convenient to store up and the cost of carriage is high, the
framework is normally designed to be foldable structure. Take also
the U.S. Pat. No. 6,702,685 and the Europe Patent EP1,459,656 for
examples, both of their structure disclosed contains foldable
framework. However, all the framework folding mechanisms of baby
swing of the prior art provide a pressing button for the operator
to press to start the action of folding the framework. This kind of
press button being exposed on the exterior surface is subject to
accidentally touch to generate folding action causing potential
hazard, thereby it is inconvenient to operate.
SUMMARY OF THE INVENTION
[0004] In order to resolve the above-mentioned problems that the
framework folding mechanism of baby swing of the prior art is
inconvenient in operation that it has the potential hazard of
accidentally folding, the invention provides a framework folding
mechanism of baby swing that includes a front supporting stand, a
rear supporting stand, and connecting base-plate. The connecting
base-plate being installed at the top ends of both the front
supporting stand and the rear supporting stand has a developed
positioning recess and a folded positioning recess for positioning.
When it comes to developing the framework, the top end of the rear
supporting stand is retained at the developed positioning recess
through a resilient element. When it comes to folding the
framework, all the operator has to do is directly pulling the
connecting base-plate to make the top end of the rear supporting
stand separate from the developed positioning recess and
subsequently rotate to move to the folded positioning recess
letting the rear supporting stand approach toward the front
supporting stand for folding. In this way, the folding mechanism of
the invention is capable of achieving the effect of safety and
conveniency.
[0005] The accomplishment of this and other objectives and the
range of suitability of the application of the invention will
become apparent from the following description and its accompanying
drawings of which:
BRIEF DESCRIPTION OF THE DRAWINGS

framework-supported seat the invention;
[0007] FIG. 2 is a schematic and isometric view of the members of
the folding mechanism of the invention;
[0008] FIG. 3 is a schematic and side view of the members of the
invention;
[0009] FIG. 4 is a side view showing the action of folding the
framework of the invention;
[0010] FIG. 5 is a side view showing the state of the folded
framework of the invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0011] FIG. 1 is a schematic and isometric view of the
framework-supported seat the invention. Shown in FIG. 1 is an
embodiment of the framework-supported seat of the invention. As
shown in FIG. 1, the framework-supported seat of the invention
includes a framework (10) connecting to an swaying arm (20) for
supporting a seat (30). The Structure is capable of providing the
baby for enjoying the swinging comfort.
[0012] FIG. 2 is a schematic and isometric view of the members of
the folding mechanism of the invention; while FIG. 3 is a schematic
and side view of the members of the invention. As shown in FIG. 1,
FIG. 2 and FIG. 3, the framework (10) consists of at least some
members such as a front supporting stand (3), a connecting
base-plate (4), and a rear supporting stand (5). Among them, the
front supporting stand (3) including a two-sided supporting rod
(31) and a supporting bottom rod (32) appears a "U" shaped
structure.
[0013] The connecting base-plate (4) being secured at the top end
of the front supporting stand (3) is connected to an end of the
swaying arm (20) that is driven by a driver (40) provided thereof
to rock. The driver (40) further drives the seat (30) to generate
back-and-forth sway. Preferably, the connecting base-plate (4) can
further includes a developed positioning recess (41) for
positioning the developed rear supporting stand (5) and a folded
positioning recess (42) for positioning the folded rear supporting
stand (5).
[0014] The rear supporting stand (5) including a two-sided
supporting rod (51) and a supporting bottom rod (52) is
substantially appeared "U" shaped structure that is similar to the
front supporting stand (3). Besides, the rear supporting stand (5)
is pivotally connected to the connecting base-plate (4) through a
guided slot (53) provided at the top end of the rear supporting
stand (5) itself.
[0015] FIG. 4 is a side view showing the action of folding the
framework of the invention; while FIG. 5 is a side view showing the
state of the folded framework of the invention. As shown in FIG. 4
and FIG. 5, based on the assembly of the above-mentioned members, a
resilient element (50) is also provided at the interior or exterior
portion of the rear supporting stand (5) for retaining the top end
of the rear supporting stand (5) in position at the developed
positioning recess (41) making the framework (10) capable of
supporting the seat (30) to sway.
[0016] Again, as shown in FIG. 4, when it comes to folding the
framework (10), the operator is capable of stepping on the
supporting bottom rod (52) of the rear supporting stand (5) by foot
and directly pulling the connecting base-plate (4) by hands to make
the top end of the rear supporting stand (5) slide along the guided
slot (53). In this way, it make the top end of the rear supporting
stand (5) separate from the developed positioning recess (41).
Consequently, the rear supporting stand (5) is capable of rotating
to approach toward the front supporting stand (3) making the top
end of the rear supporting stand (5) shift to the folded
positioning recess (42) as shown in FIG. 5, thereby completing the
folding action of the framework (10).
[0017] To avoid the rocking and swaying of the folded framework
(10), it is necessary to have the top end of the rear supporting
stand (5) at a positioning state by positioning it at the folded
positioning recess (42). Another design alternative is making use
of a slant surface to let the rear supporting stand (5) enter and
position at its positioning spot (not shown in the Figure) when the
framework (10) is in the process of folding. In the present
embodiment, the resilient element (50) is a compression spring.
[0018] Since the invention has no button-pressing design, when it
comes to folding the framework (10), all the operator has to do is
directly pulling the connecting base-plate (4) for folding, thus it
is capable of avoiding the hazard of touching a button or button by
mistake. Therefore, the invention has the advantages over those of
the prior art in the effect of safety and conveniency.
[0019] It will become apparent to those people skilled in the art
that various modifications and variations can be made to the
mechanism of the invention without departing from the scope or
spirit of the invention. In view of the foregoing description, it
is intended that all the modifications and variation fall within
the scope of the following appended claims and their
equivalents.
