sufficient stiffness to said toy to prevent the toy from wrapping
around a child, to thereby prevent suffocation" is that the toy
has a rigidity that provides sufficient resistance to bending
such that the toy is not capable of closely encircling a child's
head.
Nisbet-Baldwin discloses a toy mat formed from a strip of
plastic bubblepack packing material. By jumping on the mat, a
child can burst the bubbles which pop with an exciting cracking
sound.
Heckel discloses a tumbling and excise mat. As shown in the
Figure, the mat includes one or of a plurality of layers 1, 1' of
a closed-cell foamed synthetic material with soft elastic
properties. On the surface the core is laminated with a textile
sheeting and/or a film 3, while the underside is covered with an
antiskid netting or sheeting of rubber or a synthetic material 2.
Heckel states in column 2, lines 34-40, that
[t]he special advantage of the tumbling and exercise mat
pursuant to the innovation resides in the fact that the mat,
despite an extraordinarily small weight per unit area, has
an outstanding dynamic cushioning action. All embodiments
are readily rollable and their transport by children, even
in the case of large dimensions, is assured without any
problem. [emphasis ours]
