Toy Music Rocking Chair

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.

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.

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.

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 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.
