TECHNICAL FIELD
[0001] The present invention relates to a rocking chair and a baby chair used as a chair
or a bed for a baby especially.
BACKGROUND ART
[0002] One example of the rocking chair is disclosed in Japanese Unexamined Patent Publication
No. 11-89681. A rocking chair disclosed in this document comprises a base having four
wheels, and a seat supported on the base so that it can rock. The seat rocks at a
high position from a floor.
[0003] The rocking chair is provided for a few-month-old baby to be cradled. Therefore,
after the baby has grown up to be able to stand or walk alone, the rocking chair is
not needed in general. In other words, a conventional rocking chair has a short duration
of use.
DISCLOSURE OF THE INVENTION
[0004] It is an object of the present invention to provide a rocking chair which can be
used after a baby has grown up.
[0005] It is another object of the present invention to provide a rocking chair which gives
a neat impression in design.
[0006] It is still another object of the present invention to provide a baby chair which
gives a neat impression in design and changes its usage pattern according to circumstances.
[0007] A detachable rocking chair according to the present invention comprises a base member,
a rocking member supported by the base member so that it can rock, and a seat body
detachably supported by the rocking member. The seat body comprises self-standing
means for enabling self-standing independently.
[0008] According to the above constitution of the present invention, after the baby has
grown up to be able to stand or walk alone, the seat body can be detached from the
base member and it can stand on a floor by itself. Therefore, the child can be seated
on the seat body standing on the floor by itself. Thus, according to the present invention,
the chair can be used for a long period of time. When the chair which has been used
during an early stage of life is continuously used after the small baby has grown
up, memory of affection from a parent at the early stage of life lasts for a long
period of time, which has a favorable impact on growth of a brain of the child.
[0009] In addition, the "chair" used in this specification conceptually comprises a chair
which can be switched between the form of a chair and the form of a bed.
[0010] The self-standing means comprises a front leg part located in a front bottom of the
seat body, and a rear leg part located in a rear bottom of the seat body, for example.
In order to increase safety, it is preferable that the rocking chair comprises locking
means for locking a connection state between the rocking member and the seat body.
[0011] According to one embodiment, the rocking member comprises a pair of rocking rods
extending in a width direction at front and rear positions at a regular interval and
supported by the base member so that it can rock. The seat body comprises a pair of
notches which receives the pair of rocking rods on its bottom surface. In this constitution,
if the seat body is lifted, it can be easily detached from the base member. In this
case, in order to improve the safety, it is preferable that the seat body comprises
a moving member which can be moved between a closing position in which the notch is
closed and an opening position in which the notch is opened, a forcing member forcing
the moving member to be brought to the closing position, and an operation member for
moving the moving member.
[0012] According to one embodiment, the base member comprises a lower frame body located
below, and an upper frame body supported by the lower frame body so as to be vertical
movable. The rocking member is supported by the upper frame body so that it can rock.
As a more concrete structure, the lower frame body comprises a rectangular frame member
having four or more wheels and extending almost horizontally, and a lower vertical
frame member extending upward from one side of the rectangular frame member, and the
upper frame body comprises an upper vertical frame member aligned with the lower vertical
frame member and supported by the lower vertical frame member so as to be vertically
movable, and an upper horizontal frame member extending in a horizontal direction
from an upper end of the upper vertical frame member. The rocking member is supported
by the upper horizontal frame member so that it can rock.
[0013] When the rectangular member has four or more wheels, more stable movement can be
implemented. In addition, the term "rectangular frame" used in this specification
includes not only a rectangular configuration having four angular corners but also
a round configuration and a configuration close to a semicircle. In the case of the
rectangular frame having the round configuration, when six wheels are provided, more
stable movement can be implemented.
[0014] According to another embodiment of the present invention, the self-standing means
comprises a slide leg which is housed in the seat body and can be pulled out. For
example, the seat body comprises a backrest part which can be reclined to the form
of a bed. In this case, in order to stably support posture of the form of the bed,
the slide leg is provided so that it can be pulled out backward from a back surface
of the seat body. Preferably, a back surface of the slide leg is provided so as to
be in almost the same plane as the back surface of the seat body.
[0015] According to another aspect of the present invention, a rocking chair comprises a
base member and a seat body supported by the base member so that is can rock. The
base member comprises a horizontal frame member extending almost horizontally, and
a vertical frame member extending upward from one end of the horizontal frame member,
which has an almost L-shaped configuration as a whole. Such rocking chair having the
above constitution can give a neat impression in design. The vertical frame member
extends upward from a front end of the horizontal frame member, for example.
[0016] In the above rocking chair, it is preferable that the seat body is supported by the
base member so that its height can be adjusted. When the seat body is provided so
that its height can be adjusted, the seat body can be maintained at an optimal height
according to circumstances. In addition, preferably, the seat body is detachably supported
by the base member. Thus, since the seat body can be used independently, it is more
convenient. In this case, preferably, the seat body comprises self-standing means
for enabling self-standing independently.
[0017] Preferably, the horizontal frame member and the vertical frame member are provided
so that they can be folded to each other. In this constitution, since the base member
can be compactly folded when it is not used, a dimension of the base member in a folded
state can be reduced.
[0018] According to one embodiment, the base member comprises an upper horizontal frame
member extending almost horizontally from an upper end of the vertical frame member,
and the seat body is supported by the upper horizontal frame member so that it can
rock. In this case, the upper horizontal frame member and the vertical frame member

floor.
[0033] As means for enabling the seat body to stand by itself is not limited to the illustrated
one. For example, the seat body may have folding legs and the legs are set so that
the seat body can stand by itself according to need.
[0034] A connection structure between the seat body 30 and the rocking member 20 will be
described in detail with reference to Figs. 5 and 6.
[0035] A p air of rail members 40 extending backward and forward is mounted on both sides
of the bottom surface of the seat body 30 and fixed thereto. Each rail member 40 has
the front notch 37 and the rear notch 38 which receive the front rocking rod 21 and
the rear rocking rod 22, respectively.
[0036] As shown in Fig. 6, each rail member 40 houses a front slider 41 and a rear slider
42 which can be moved between a closing position in which the front notch 37 and the
rear notch 38 are closed and an opening position in which they are opened. The front
slider 41 has a locking part 41a which traps the front rocking rod 21 received in
the front notch 37 and the rear slider 42 has a locking part 42a which traps the rear
rocking rod 22 received in the rear notch 38.
[0037] The front slider 41 has a connection pin 44 having a head at its rear end. A connection
member 43 is positioned between the front slider 41 and the rear slider 42. A front
end of the connection member 43 is positioned on an axis part of the connection pin
44, and a rear end thereof abuts on the rear slider 42. A spring 45 fitted in the
axis part of the connection pin 44 constantly forces the front slider 41 toward the
closing position.
[0038] The pair of rear sliders 42 positioned on the right and left sides is connected to
each other through a setscrew 49 and an operation rod 48. Each rail member 40 has
an elongated hole 47 through which the setscrew 49 passes. The operation rod 48 extending
in the width direction can be moved back and forth within a range in which the setscrew
49 can be moved in the elongated hole 47. A spring 46 abutting on a rear end of the
rear slider 42 constantly forces the rear slider 42 toward the closing position.
[0039] A connection state between the seat body 30 and the front and rear rocking rods 21
and 22 can be stably maintained when the locking parts 41a and 42a of the front and
rear sliders 41 and 42 are positioned under the rocking rods 21 and 22, respectively.
[0040] When the seat body 30 is to be detached from the base member 10, the operation rod
48 extending in the width direction is grasped and drawn backward with a hand. Then,
as shown in Fig. 7, the front and rear sliders 41 and 42 are moved backward and the
notches 37 and 38 are opened. In this state, as the seat body 30 is lifted, the seat
body 30 can be easily detached from the base member 10.
[0041] The seat body 30 is mounted on the base member 10 as follows. As shown in Fig. 8,
first, the locking part 42a of the rear slider 42 is brought to the rear rocking rod
22 and in this state, the rear part of the seat body 30 is moved downward. Then, the
rear slider 42 is moved backward so as to compress the spring 46 and the rear rocking
rod 22 enters the rear notch 38. Then, as shown in Fig. 9, the locking part 41a of
the front slider 41 is brought to the front rocking rod 21 and in this state, the
front part of the seat body 30 is moved downward. Then, the front slider 41 is moved
backward so as to compress the spring 45 and the front rocking rod 21 enters the front
notch 37.
[0042] According to the illustrated embodiment, a height of the seat body 30 supported on
the base member 10 can be changed. A structure for implementing it will be described
with reference to Figs. 10 and 11. As described above, the base member 10 comprises
the lower vertical frame member 14 and the upper vertical frame member 16 in the form
of the pipes. The lower vertical frame member 14 is inserted into the upper vertical
frame member 16.
[0043] A resin bracket 50 is fixed to a lower end of the upper vertical frame member 16.
As shown in Fig. 10, a lever 51 is turnably mounted on the resin bracket 50 through
an axis 52. A rear end of the lever 51 forms an operation button 58 and a lock pin
54 is mounted on its rear end through a connection axis 55 and a hole 56. In a state
shown in Fig. 10, a tip end of the lock pin 54 passes through the resin bracket 50
and a hole 57 of the upper vertical frame member 16 and engages in a hole 14a of the
lower vertical frame member 14 to prohibit relative movement of the upper and lower
vertical frame members 14 and 16. This state can be stably maintained by force of
a spring 53.
[0044] When the height of the seat body 30 is to be changed, as shown in Fig. 11, the operation
button 58 is moved upward and the lever 51 is turned counterclockwise. When the lever
51 is turned, the lock pin 54 is moved to the right in the figure and separated from
the hole 14a of the lower vertical frame member 14. Therefore, the upper vertical
frame member 16 can be vertically moved together with the seat body 30.
[0045] Figs. 12 to 14 show a seat body 100 according to another embodiment of the present
invention. The illustrated seat body 100 comprises a seat part 101, a backrest part
102 which is retained by the seat part 101 so that it can be reclined, and a head
guard part 103 turnably mounted on an upper end of the backrest part 102. The backrest
part 102 can be reclined to the form of a bed as shown in Fig. 14. When the seat body
100 is in the form of a chair as shown in Fig. 12, the head guard 103 is in almost
the same plane as a backrest surface of the backrest part 102 or bent so as to form
a slightly inclined angle with respect to the backrest surface in order to open an
upper region of the backrest part 102. Meanwhile, when the seat body 100 is in the
formed of the bed as shown in Fig. 14, the head guard part 103 is provided so as to
form a bending angle from the backrest surface in order to protect a top of the head
of the child.
[0046] A front notch 137 and a rear notch 138 are formed in a bottom surface of the seat
part 101. The front notch 137 and the rear notch 138 have the same effect as in the
front and rear notches 37 and 38 in the above embodiment. That is, the front notch
137 and the rear notch 138 receive a front rocking rod 21 and a rear rocking rod 22
supported by a base member so that they can rock.
[0047] The seat part 101 comprises a slide leg 110 which is housed in its rear part and
can be pulled out backward. The slide leg 110 comprises an inverted U-shaped member
111 which is clearly shown in Fig. 13, and two slide rods 112 extending backward and
forward. As shown in Figs. 12 and 13, in a state in which the slide leg 110 is housed,
a back surface of the slide leg 110, that is, a back surface of the inverted U-shaped
member 111 is provided so as to be in almost the same plane as a back surface of the
seat part 101.
[0048] As shown in Fig. 14, when the seat body 100 is set on a floor in the form of the
bed, the seat part 101 could become unstable when a body weight of the child is applied
to the largely reclined backrest part 102. Thus, as shown in Fig. 14, the slide leg
110 is pulled out backward to stably support the seat body 100 in the form of the
bed.
[0049] Although one embodiment of the present invention has been described above with reference
to the drawings, various kinds of modifications and variation can be made within the
same or equivalent scope of the present invention. For example, the configuration
of the rocking member is not limited to the rod and various kinds of configurations
can be applied thereto. Similarly, the means for enabling the seat body to stand by
itself may have various kinds of configurations.
[0050] Furthermore, although the seat body can rock and be detachable with respect to the
