Mobile

Abstract

Provided is a mobile that includes: (a) a primary attachment point; (b) a set of at least two concentric rings including a main ring having a rotary axis with first and second ends, and at least one additional ring having its own rotary axis and carried by the main ring at the ends of the own rotary axis, each of the rings rotatable about its rotary axis; and (c) a main support element attached to the primary attachment point, configured to engage first and second ends of the rotary axis of the main ring, and being subject to rotational displacement so that the first end is sometimes above and sometimes below the second end.

Description

FIELD OF THE INVENTION[0001]This invention relates to mobiles, for example mobiles adapted for installation in a baby care device such as a crib or playpen.BACKGROUND OF THE INVENTION[0002]The ability to recognize differences in the shapes and sizes of various objects is not innate or inherent but must be acquired. This is best taught at an early age by play, for the most effective toy for a child is one which instructs as well as entertains the player.[0003]A classic toy serving to teach a child how to distinguish between objects which differ in shape, color and size, provides a player with a set of diverse geometric objects and a playing board having apertures therein. Each aperture in the board has a geometry which corresponds to only one of the pieces in the set. Hence when a player seeks to fit a triangular piece into an aperture, by trial and error he finds the one aperture in the board that will accept the triangular piece. The child in playing with this toy must take size in...

AI Technical Summary

Benefits of technology

[0020]An aspect of some embodiments of the invention relates to a mobile including a rotational control mechanism adapted to limit rotation of at least one of the support canopies to a single direction. In some exemplary embodiments of the invention, the control mechanism employs a ratchet. Optionally, a resistance force of the ratchet provides a threshold force. In some exemplary embodiments of the invention, use of a threshold force causes the canopy to perform a single rapid rotation through a defined arc instead of a more gradual rotation. Optionally, the single rapid rotation causes items dangling from the canopy to sharply move thereby drawing attention of an infant observer thereto.

Problems solved by technology

Thus if an aperture on the board is a circular opening with a one inch diameter, it will not accept a circular disc having a one-and-a-half inch diameter.

But the balance is upset by natural air currents flowing in the space occupied by the mobile.
