Abstract

A toy with a ring-shaped body having multiple sections each forming a portion of the ring-shaped body and each having a tubular base portion. At least a first tab projects radially outward from the tubular base portion of a first section of the multiple sections. Surface features protrude from at least one of the first tab and the tubular base portion of at least one of the multiple sections. At least a first pressure sensor is embedded in the first tab and operates to activate a first electrical device in response to pressure applied to the first tab exceeding a pressure threshold. Activation of the first electrical device produces light, or sound, or vibrates.

First claim

The invention claimed is:

1. A toy comprising:
a ring-shaped body comprising multiple sections, each section of the multiple sections forming a portion of the ring-shaped body and having a tubular base portion, each adjacent pair of the multiple sections being separated by a wall, each of the multiple sections having an enclosed internal cavity defined therein, the enclosed internal cavities being separated by the walls between the adjacent pairs of the multiple sections;
at least a first tab projecting radially outward from the tubular base portion of a first section of the multiple sections;
at least a second tab projecting radially outward from the tubular base portion of a second section of the multiple sections;
surface features protruding from at least one of the first tab and the tubular base portion of at least one of the multiple sections; and
at least a first pressure sensor embedded in the first tab, the first pressure sensor operating to activate a first electrical device in response to pressure applied to the first tab exceeding a pressure threshold, wherein activation of the first electrical device produces light, sound, or vibrations;
wherein:
the multiple sections of the ring-shaped body are four arcuate sections each forming a 90-degree quadrant of the ring-shaped body;
the tubular base portions of the first and second sections are immediately adjacent to each other on the ring-shaped body so as to form a first half of the ring-shaped body; and
the tubular base portions of third and fourth sections of the multiple sections are immediately adjacent to each other on the ring-shaped body so as to form a second half of the ring-shaped body and do not comprise tabs that project radially outward from the tubular base portions thereof.
