Abstract
A large pet exerciser utilizes but two readily available major components. One is a galvanized pipe or post embedded in concrete. The other major component is an extension or tension spring having a loop or ring on each end. The spring is anchored in the top of the post by means of one loop while a leash is connected to the other or extending top loop. The spring not only elongates when subject to tensile forces, but being mostly free of the post flexes or bends laterally of the post axis in any azimuth or direction. Both actions of the spring exert a bias on any pull by a pet secured to a leash in turn secured to the top or projecting end of the spring. This provides significant decelerating strain relief.
Claims7
A pet exerciser comprising a hollow post embedded in the ground, an extension spring having an upper and lower end, means operative to anchor the lower end of the spring directly in the interior top of said hollow post with the upper end projecting above and free of the post, means to tether a pet directly to said upper end of said spring, and means to embed the lower end of the hollow post in concrete, with said concrete filling the interior lower end of said hollow post.
A pet exerciser comprising a post embedded in the ground, an extension spring having an upper and lower end, means operative to anchor the lower end of the spring in the top of said post with the upper end projecting above and free of the post, means to tether a pet directly to said upper end of said spring, means to embed the lower end of the post in concrete, said post being hollow and said concrete filling the lower end of said post, and a drain hole in said post at the level of concrete embedment.
A pet exerciser comprising a post embedded in the ground, an extension spring having an upper and lower end, means operative to anchor the lower end of the spring in the top of said post with the upper end projecting above and free of the post, means to tether a pet directly to said upper end of said spring, and means to embed the lower end of the post in concrete, said post being hollow and said concrete filling the lower end of said post, and a bushing in the top of the post through which the spring projects.
