Abstract
Official abstract text for this publication.
A composite trampoline enclosure system has a trampoline with a trampoline frame and a trampoline bed. The trampoline enclosure is mounted to the trampoline. The trampoline enclosure further includes an enclosure pole formed as a tubular post, and an endcap. The endcap fits over the tubular post. A flexible top line is made of polyethylene or polypropylene. The flexible top line connects to the endcap. The flexible top line supports the trampoline enclosure netting. An extended coil spring is whipped in a helical orientation around an external circumferential periphery of the flexible top line. The trampoline enclosure netting is extended around the trampoline bed. The trampoline enclosure netting is supported by the trampoline pole. The extended coil spring is preferably made of spring steel. The flexible top line is preferably made of a high density polyethylene tube.
First claim
Opening claim text (preview).
The invention claimed is: 1. A composite trampoline enclosure system having: a trampoline with a trampoline frame and a trampoline bed; a trampoline enclosure mounted to the trampoline, wherein the trampoline enclosure further includes: an enclosure pole formed as a tubular post; an endcap, wherein the endcap fits over the tubular post; a trampoline enclosure netting extended around the trampoline bed, where the trampoline enclosure netting is supported by the trampoline pole, wherein the improvement is: a. a flexible top line made of polypropylene or polyethylene, wherein the flexible top line connects to the endcap, wherein the flexible top line supports the trampoline enclosure netting, wherein the flexible top line is formed as a flexible top rod; and b. an extended coil spring whipped, in a helical orientation, around an external surface of the flexible top line, wherein the extended coil spring has a pretension against the flexible top rod when mounted to the flexible top rod. 2. The composite trampoline enclosure system of claim 1 , wherein the extended coil spring is made of spring steel. 3. The composite trampoline enclosure system of claim 1 , wherein the flexible top line is made of a high density polyethylene tube. 4. The composite trampoline enclosure system of claim 1 , wherein the flexible top line comprises high density polyethylene. 5. The composite trampoline enclosure system of claim 1 , wherein the flexible top line made of high density polyethylene is made with a coil spring slot formed as a helical groove along at least a portion of the length of the flexible top line, wherein the coil spring slot receives the coil spring that is extended into the coil spring slot. 6. The composite trampoline enclosure system of claim 5 , further including an epoxy coating applied over the coil spring slot after the coil spring is extended into the coil spring slot.
