Claim 1
Independent Claim
196 words
An activity device for animals, said device comprising a revolvable drum having an interior along which an animal is fReely movable, stationary means for permitting an animal to climb thereupon and extending substantially inwardly of said drum, support means for permitting rotation of said drum relative to said stationary means as an animal moves along the interior of said drum, said stationary means including a housing in which is defined a platform, said housing having an exterior radially spaced from the interior of said drum and defining a radial clearance with the latter toward which is attracted an animal of habitual tunnel-burrowing inclination, said support means including a flange-carrying bracket fixed to said housing for removably overhanging freely upon an externally associated vertical carrier source, said support means further including a shaft extending through said housing upon which is rotatably journaled said drum, said drum including an open front portion through which projects an open rear portion of said housing in opposing relation, said drum and housing each including a generally closed portion operatively associated with said shaft, said closed portion of said drum acting as a wall for said open rear portion of said housing.
Claim 2
Dependent Claim
196 words
An activity device for animals, said device comprising a revolvable drum having an interior along which an animal is fReely movable, stationary means for permitting an animal to climb thereupon and extending substantially inwardly of said drum, support means for permitting rotation of said drum relative to said stationary means as an animal moves along the interior of said drum, said stationary means including a housing in which is defined a platform, said housing having an exterior radially spaced from the interior of said drum and defining a radial clearance with the latter toward which is attracted an animal of habitual tunnel-burrowing inclination, said support means including a flange-carrying bracket fixed to said housing for removably overhanging freely upon an externally associated vertical carrier source, said support means further including a shaft extending through said housing upon which is rotatably journaled said drum, said drum including an open front portion through which projects an open rear portion of said housing in opposing relation, said drum and housing each including a generally closed portion operatively associated with said shaft, said closed portion of said drum acting as a wall for said open rear portion of said housing.
Claim 3
Dependent Claim
184 words
An activity device for animals, said device comprising a revolvable drum having an interior along which an animal is freely movably, stationary means for permitting an animal to climb thereupon and extending substantially inwardly of said drum, support means for permitting rotation of said drum relative to said stationary means as an animal moves along the interior of said drum, said stationary means including a housing in which is defined a platform, said housing having an exterior radially spaced from the interior of said drum and defining a radial clearance with the latter toward which is attracted an animal of habitual tunnel-burrowing inclination, said support means including a bracket fixed to said housing for removably overhanging freely upon an externally associated vertical carrier source, said support means further including a shaft extending through said housing upon which is rotatably journaled said drum, said bracket including a flange provided with a generally flat portion of sufficient longitudinal and lateral extent, and said flat portion extending generally parallel to said shaft for self-supporting said housing and drum in an operative condition on a lower horizontal surface.
Claim 4
Dependent Claim
184 words
An activity device for animals, said device comprising a revolvable drum having an interior along which an animal is freely movably, stationary means for permitting an animal to climb thereupon and extending substantially inwardly of said drum, support means for permitting rotation of said drum relative to said stationary means as an animal moves along the interior of said drum, said stationary means including a housing in which is defined a platform, said housing having an exterior radially spaced from the interior of said drum and defining a radial clearance with the latter toward which is attracted an animal of habitual tunnel-burrowing inclination, said support means including a bracket fixed to said housing for removably overhanging freely upon an externally associated vertical carrier source, said support means further including a shaft extending through said housing upon which is rotatably journaled said drum, said bracket including a flange provided with a generally flat portion of sufficient longitudinal and lateral extent, and said flat portion extending generally parallel to said shaft for self-supporting said housing and drum in an operative condition on a lower horizontal surface.
Claim 5
Dependent Claim
53 words
An activity device as claimed in claim 2 wherein said bracket includes means for permitting an animal to climb upwardly therealong into said housing when self-supporting said housing and drum on a lower horizontal surface, and means for preventing an animal from climbing upwardly therealong when overhanging an externally associated vertical carrier source.
Claim 6
Dependent Claim
24 words
An activity device as claimed in claim 3 wherein said means which permits an animal to climb upwardly along said bracket includes successive steps.
Claim 7
Dependent Claim
65 words
An activity device as claimed in claim 2 wherein said housing is provided with an exterior which is sufficiently spaced radially from the interior of said drum at least in part at two radially opposite directions for permitting an animal to move freely along the interior of said drum when said bracket self-supports said housing and drum or overhangs an externally associated vertical carrier source.
Claim 8
Dependent Claim
20 words
An activity device as claimed in claim 2 wherein said drum includes a generally cylindrical roughingly textured internal wall portion.
Claim 9
Dependent Claim
22 words
An activity device as claimed in claim 6 wherein said textured internal wall portion includes a circumferential array of spaced parallel ribs.
Claim 10
Dependent Claim
153 words
An activity device for animals, said device comprising a revolvable drum having an interior along which an animal is freely movable, stationary means extending substantially inwardly of said drum, support means for permitting rotation of said drum relative to said stationary means as an animal moves along the interior of said drum, said stationary means and said support means fixedly connected to one another, said stationary means including first and second pLatforms upon which an animal may climb upon and rest, said first platform being horizontally disposed within said drum in a fixed relation with respect to said support means, said first platform having an exterior spaced from the interior of said drum and defining an animal exercise area with the latter wherein an animal may run freely and cause rotation of said drum, said second platform being medially disposed and vertically spaced from said first platform, and said first platform being arcuate.
Claim 11
Dependent Claim
153 words
An activity device for animals, said device comprising a revolvable drum having an interior along which an animal is freely movable, stationary means extending substantially inwardly of said drum, support means for permitting rotation of said drum relative to said stationary means as an animal moves along the interior of said drum, said stationary means and said support means fixedly connected to one another, said stationary means including first and second pLatforms upon which an animal may climb upon and rest, said first platform being horizontally disposed within said drum in a fixed relation with respect to said support means, said first platform having an exterior spaced from the interior of said drum and defining an animal exercise area with the latter wherein an animal may run freely and cause rotation of said drum, said second platform being medially disposed and vertically spaced from said first platform, and said first platform being arcuate.
