AI Technical Summary

Benefits of technology

The present invention provides a cradle that can swing smoothly and stably without producing much noise. The cradle uses an electromagnetic device to repel or attract magnets, which then drives the table board to swing in a way that reduces the noise generated by conventional motors. The cradle is easy to assemble, maintain, and has a low cost of production.

Problems solved by technology

However, the motor produces great noise during operation, thereby affecting the baby's sleeping.
In addition, the conventional cradle is operated by a mechanic swinging action, so that the conventional cradle cannot swing smoothly and stably.
Further, the conventional cradle has a complicated construction, thereby increasing the cost of production.

Embodiment Construction

[0013]Referring to the drawings and initially to FIGS. 1-4, a cradle in accordance with the preferred embodiment of the present invention comprises a base unit 1, a swinging unit 2 mounted on the base unit 1, a table board 3 mounted on the swinging unit 2, and an electromagnetic unit 4 mounted between the base unit 1 and the table board 3.

[0014]The base unit 1 includes two stands 11 and two side support rods 13 secured between the two stands 11. Each of the two stands 11 is substantially inverted U-shaped and has two distal ends extending downward. One of the two stands 11 is provided with a recessed portion 12. The recessed portion 12 is located at a middle position of an upper portion of the one of the two stands 11. The two side support rods 13 flank the recessed portion 12 of the one of the two stands 11.

[0015]The swinging unit 2 includes two primary swinging brackets 23, four secondary swinging brackets 21, two links 22 and an enclosed bar 25. Two of the four secondary swinging...

Abstract

A cradle includes a base unit, a swinging unit mounted on the base unit, a table board mounted on the swinging unit, and an electromagnetic unit mounted between the base unit and the table board. The electromagnetic unit includes a housing secured on the base unit, an electromagnetic device mounted in the housing, a box mounted on the table board and corresponding to the electromagnetic device, and two magnet sets mounted in the box. Thus, the electromagnetic device is started and produces a magnetism to repel or attract the two magnet sets which drive the table board to swing reciprocally.

Description

BACKGROUND OF THE INVENTION1. Field of the Invention[0001]The present invention relates to a cradle and, more particularly, to an electromagnetic swinging cradle for placing a baby.2. Description of the Related Art[0002]The cradle is used to place a baby so that the baby can lie and sleep in the cradle to facilitate the baby minder nursing the baby. A conventional cradle comprises a motor which drives a linkage to move reciprocally so as to swing the cradle. However, the motor produces great noise during operation, thereby affecting the baby's sleeping. In addition, the conventional cradle is operated by a mechanic swinging action, so that the conventional cradle cannot swing smoothly and stably. Further, the conventional cradle has a complicated construction, thereby increasing the cost of production.BRIEF SUMMARY OF THE INVENTION[0003]The primary objective of the present invention is to provide a cradle that performs a swinging action reciprocally in an electromagnetically actuati...
