Rolling pet toy
View Patent ↗An improved pet toy is generally ring-like and is rollable along a surface, such as the ground. The pet toy includes a resilient foam core that is surrounded by an elastomeric outboard portion and a fabric inboard portion that are affixed to one another and to the core. The outboard portion has a roughened surface that provides traction with the ground and enables the pet toy to roll in various fashions. The fabric inboard portion includes a stiffening structure in the form of a rib that resists deformation of the pet toy in a radial direction toward and away from a center of the toy.
1. A pet toy structured to be rollable along a surface and comprising:
a ring-like body extending in a circumferential direction about a central opening, the ring-like body comprising,
an exterior part defining an exterior surface having an inboard portion and an outboard portion, the inboard portion being situated adjacent the central opening to define an inner circumferential surface of the exterior surface and formed at least in part of a plurality of interconnected fibers, the inboard portion having a protuberant rib extending in a circumferential direction about the opening and protruding toward a center of the opening, the rib being structured to resist deformation of the body in a radial direction from the center,
the outboard portion being disposed opposite the inboard portion to define an outer circumferential surface of the exterior surface that is in part arcuate, the outboard portion having a pair of oppositely facing axial surfaces that are separated by a distance that is a maximum width of the ring-like body, the outboard portion being substantially entirely formed of an elastomeric material such that the maximum width of the ring-like body is defined by the elastomeric material; and
an interior part having a resilient core disposed inside of the outboard portion and the inboard portion, the outboard portion having a higher density than a density of the resilient core so that a mass of the ring-like body is greater at the outboard portion.
2. The pet toy of claim 1 , wherein
the inboard portion and the outboard portion are directly connected together.
3. The pet toy of claim 1 , wherein
the inboard portion and the outboard portion are directly affixed to one another and are each directly affixed to the core.
4. The pet toy of claim 1 , wherein
the body further comprises a bridging element extending across the opening between a first portion of the rib and a second portion of the rib, the first and second portions being diametrically opposed.
5. The pet toy of claim 1 , wherein
the body extends in the circumferential direction at a fixed radius from the center of the opening and includes at least a first undulation, at least a portion of the body extending at the fixed radius in a direction transverse to the circumferential direction.
6. The pet toy of claim 1 , wherein
the body has a substantially unvarying thickness throughout the circumferential extent of the body.
7. The pet toy of claim 6 , wherein
the body has a substantially unvarying width throughout the circumferential extent of the body.
8. The pet toy of claim 6 , wherein
the body has a first width and a second width, the first width being unvarying, the second width being different from the first width, the first and second widths extending in a direction orthogonal to the radial and circumferential directions.
9. The pet toy of claim 1 , wherein
the core is formed at least in part of a resilient foam.
10. The pet toy of claim 1 , wherein
the body includes an outer wall, an inner wall, a first sidewall, and a second sidewall that are layers of the body that enclose the core.
11. The pet toy of claim 10 , wherein
the outboard portion forms at least a portion of each of the first and second sidewalls.
12. The pet toy of claim 10 , wherein
the rib defines the inner circumferential surface of the body.
13. The pet toy of claim 1 , wherein
the maximum thickness of the outboard portion being greater than a maximum thickness of the inboard portion.
14. The pet toy of claim 1 , wherein
the outboard portion further includes a pair of ledges, each of the ledges being affixed to an end of the inboard portion at an overlapping area of the inboard and outboard portions.
15. The pet toy of claim 1 , wherein
the protuberant rib defines the inner circumferential surface and has an overlapping area of the first and second.
16. The pet toy of claim 15 , wherein
a thickness of the protuberant rib is greater than a combined thickness of the first and second segments of the inboard portion.
17. The pet toy of claim 15 , wherein
the overlapping area of the first and second segments includes a seam affixing the first and second segments together such that the protuberant rib is a stiffened portion of the ring-like body.
