Toy music rocking chair
Abstract
A toy music rocking chair comprises a music box and a
transmission system. The transmission system further consists of an
arm fixed to the shaft of the music box, a stub extending from the
arm, a reciprocating plate having a lateral slot for the stub to
fit in, a reciprocating rod and a slide mechanism connected to the
reciprocating rod and installed in the head of the doll rocker
serving as eyes so that when the shaft turns, the rotary motion of
the stub can be changed into reciprocating motion of the
reciprocating plate and rod which, in turn, cause the rocking chair
to sway back and forth, and the eyelids to open and close as though
the doll rocker is sleepy.

(e) a guide socket on the top of the box;
(f) a reciprocating rod disposed through the guide socket;
(g) a doll rocker supported on the seat, the doll rocker including
a head; and
(h) a slide mechanism disposed within the head of the doll rocker
and including a pair of guards painted like eyeballs, a pair of
movable slides serving as eyelids, the slides being connected to

3. A toy device adapted for movement comprising:
a) a music box supported on the toy device, the music box including
a rotatable driving shaft having a protruding end, the music box
comprising a power source for causing movement of the toy
device;
b) a transmission system including a rotatable element secured to
the protruding end of the driving shaft so as to rotate
therewith;
c) a stub extending from the rotatable element so as to rotate
therewith; and,
d) a reciprocating plate defining a follower surface in contact
with the stub such that rotary motion of the rotatable driving
shaft of the music box causes rotary motion of the rotatable
element which, in turn, causes rectilinear reciprocating motion of
the plate whereby such rectilinear motion of the plate imparts
movement to the toy device. .Iaddend. .Iadd.4. The toy device
according to claim 3 further comprising guide means operatively
associated with the reciprocating plate to guide during its
reciprocating movement. .Iaddend. .Iadd.5. The toy device according
to claim 4 wherein the guide means is associated with the music
box. .Iaddend. .Iadd.6. The toy device according to claim 3 wherein
the toy has movable elements and further comprising:
a) a reciprocating rod operatively attached to the reciprocating
plate so as to reciprocate therewith; and,
b) means attaching the rod to the movable elements such that
reciprocation
of the rod causes movement of the elements. .Iaddend. .Iadd.7. The
toy device according to claim 3 further comprising rocker means
associated with the toy device and located such that the
rectilinear reciprocating motion of the plate imparts a rocking
motion to the toy device relative to the support surface. .Iaddend.
.Iadd.8. The toy device according to claim 3 wherein the
reciprocating plate has a portion in contact with a support surface
such that the rectilinear reciprocating motion of the plate imparts
movement to the toy device relative to the support surface.
Description
BACKGROUND OF THE INVENTION
There has been a kind of toy comprising a music box and a doll or
wooden horse. Driven by the shaft of the music box, the doll or
wooden horse mounted on a platform will revolve back and forth
while the music box gives a melody. Many curious people like it
very much.
To make it more interesting and to have its music and movement
become more natural and harmonous, this invention improves the
simple, rotary motion of the conventional toy and provides a music
rocking chair with a doll sitting in. With the turning of the shaft
of the music box, the chair sways back and forth and the eyelids of
the doll open and close. The movement is so natural that the doll
rocker appears to be in a sleepy state.
SUMMARY OF THE INVENTION
This invention relates to a music rocking chair comprising a music
box and a transmission system which can change rotary motion into
reciprocating motion. The reciprocating plate of the transmission
system can make the rocking chair sway back and forth and the
reciprocating rod can cause the eyelids to open and close while the
music box produces soft, high-pitched sounds of great delicacy.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a vertical view of the toy music rocking chair of this
invention.
FIG. 2 is a longitudinal section of the said chair.
FIG. 3 is a sectional view of the head of the doll rocker of this
invention.
FIG. 4 is a bottom view of the said chair.
FIG. 5 is a view taken along the line A--A of FIG. 3.
FIG. 6 is a view taken along the line B--B of FIG. 5.
DESCRIPTION OF THE PREFERRED EMBODIMENT
FIG. 1 shows a doll rocker sitting in a rocking chair. As shown in
FIG. 2, the rocking chair has a box B under the seat and a
music-box movement 2 in the box B. The shaft 22 of the music box
has an arm 3 with a stub 31. The stub 31 is parallel to the shaft
22 and extends from the rear and of the arm 3.
As shown in the FIG. 2 and FIG. 4, the shaft 22 of the music box 2
has an arm 3 at the rear end and the arm 3 has a stub 31 extending
from the rear end. The stub 31 is fitted in the slot 52 of the
reciprocating plate 5. With the shaft 22 rotating, the stub 31
revolves and moves in the slot 52 of the reciprocating plate 5. The
rotary motion of the stub 31 causes the reciprocating plate 5 to
slide up and down. Two struts 4, 4a provided in the box B have
slide grooves 41, 41a respectively for the reciprocating plate 5 to
slide. The lateral slot 52 of the reciprocating plate 5 is greater
in width than the diameter of the stub and in length than the
diameter of the circle in which the stub 31 moves. When the
reciprocating plate 5 goes up, the lower part 53 of the plate 5
leaves the ground slightly so that the rocking chair can sway back
completely. When the reciprocating plate 5 goes down and its lower
part 53 touches the ground, it props up the chair and makes it sway
forth. Based on this, the length of the lower part 53 of the
reciprocating plate is determined.
A guide socket 6 is provided in the top of the box B to guide the
reciprocating rod 60 so that the rod 60 is in alignment with the
top end of the reciprocating plate 5. The reciprocating rod 60 is
slidably fitted in the guide socket 6 and connected with a
connecting rod 71 to the slide mechanism 7. The reciprocating rod
60 pushed by the reciprocating plate 5 carries the motion of the
shaft 22 to the control handle 71 and makes the slide plate 70
(eyelid) to slide up and down.
The said slide mechanism 7 is in the head of the doll rocker. As
shown in FIGS. 5 and 6, a guard 72 is provided in the eyelet E of
the doll and painted as eyeballs. A specific gap is provided in
front of the guard 72 for the slide plate 70 to slide in. The slide
plate 70 can slide down from the upper rim of the eyelet E as a
human eyelid. The slide plate 70 is connected to the reciprocating
rod at an appropriate place on the central line by means of a
connecting rod 71 so the slide plate 70 can slide up and down
slowly, with the motion of the reciprocating rod.
Accordingly, while the music box produces soft, high-pitched sounds
of great delicacy, the shaft 22 drives the reciprocating plate 5
through the arm 3 and stub 31 to make the rocking chair to sway
back and forth, and to push the reciprocating rod to cause the
eyelids to close slowly as though the doll rocker is sleepy.
