Rubber tree rain guard seal assembly

Abstract

The main objective of this invention is to improve the efficiency and service life of a rubber tree rain guard seal. The performance of existing rubber tree rain guard seals depends on a fixed mechanical and or chemical attachment of the seal to the tree. These methods of attachment prevent the seal from expanding with the circumferential growth of the tree resulting in premature seal failure and damage to the tree within a year of operation. In this invention the seal is comprised of five components that are not fixed to the tree, allowing the seal to expand along with tree growth. An adjustable outer seal connector regulates the pressure required to establish consistent sealing contact against the tree, thus providing extended service life of the seal assembly. The seal assembly comes apart for easy maintenance.

Claims

1. A rubber tree rain guard Seal Assembly comprising: an Inner Seal Ring configured to establish sealing engagement with a rubber tree; said Inner Seal Ring consisting of a soft, non-hardening, flexible, non-adhesive compound in contact with the tree, wherein said Inner Seal Ring does not absorb water, does not adhere to the tree, and can be readily removed by peeling off the tree; an Outer Seal Ring consisting of polyvinyl chloride, medium density or closed cell foam tape, wherein the Outer Seal Ring is resistant to fungus, mold and mildew, wherein the outer Seal Ring has a pre-determined compression set value, and wherein the length of said Outer Seal Ring is equal to the circumference of the tree; an Outer Seal Connector, wherein the length of the Outer Seal Connector is calculated based on the gap that said Outer Seal Connector has to span to connect the ends of said Outer Seal Ring; and a first fastener located at a first end of the Outer Seal Ring; and a second fastener located at the second end of the Outer Seal Ring; wherein the ends of said Outer Seal Ring are glued to the first fastener and the second fastener, respectively; wherein said first fastener and said second fastener are attached to the ends of said Outer Seal Connector; wherein said rubber tree rain guard Seal Assembly has no parts physically or chemically attached to said rubber tree by use of either mechanical fasteners or adhesive glues; and wherein said Inner Seal Ring is configured to absorb the forces being applied by the expansion of the tree without detriment to the Seal established by said Inner Seal Ring against said rubber tree.

2. A method of using the Seal Assembly of claim 1, the method comprising the steps of: using said Outer Seal Connector as a pressure controller to control the pressure applied by said Outer Seal Ring to said Inner Seal Ring; and causing said Inner Seal Ring pressure being applied against the tree to increase or decrease as required to maintain said Inner Seal Ring sealing contact with said rubber tree.

DETAILED DESCRIPTION OF THE INVENTION

(19) the inner seal ring FIG. 5, the outer seal ring FIG. 4, the two fasteners FIG. 2 and FIG. 3 and the outer seal connector FIG. 1 are cut to size based on the circumference and the condition of the bark of the tree. The typical size of the outer seal ring for trees 20″ to 30″ in circumference would be, ½″ thick by 1-½″ wide, with the length being determined by the circumference of the tree. The thickness of the inner seal ring will be determined by how undulating the bark of the tree is. The width of the hook and loop adhesive tape will be 1″ and cut to different lengths based on tree circumference.

(20) fastener #1 FIG. 2 and fastener #2 FIG. 3, are then glued to the first end and the second end of the outer seal ring FIG. 4.

(21) FIG. 1 one end of the hook and loop outer seal connector is attached to the first hook and loop Fastener #1 and the other end of the outer seal connector to the second hook and loop fastener #2.

(22) FIG. 4 the outer seal ring is then pulled tight around the tree by first unhooking one end of the outer seal connector from one of the fasteners, then pulling the outer seal ring tighter around the tree and reattaching the outer seal connector to the fastener from which it was unhooked.

(23) this action forces the Inner Seal Ring against the bark of the tree establishing a seal with the tree bark. By changing the location of either of the ends of the hook and loop outer seal connector, relative to its existing location on either of the hook and loop fasteners, the pressure that the inner seal ring FIG. 5 applies to the tree will be changed. Seal integrity is maintained by this ability of the hook and loop outer seal connector to be relocated to a new location on either of the hook and loop Fasteners FIG. 2 or FIG. 3 thereby providing the pressure required to continue establishing a seal against the tree by the inner seal ring.

(24) the ability of the outer seal ring foam material to compress, as an equal and opposite force is being applied to it by the Inner seal ring, causes the outer seal ring to also extend the service life of the seal assembly as it accommodates tree growth. This feature delays the adjustment to the hook and loop outer seal connector that would be required to further accommodate tree expansion.

(25) Therefore the physical composition of both the inner seal ring and the outer seal ring also contribute to the overall service life of the tree. The final accommodation to the circumferential growth of the tree will be achieved by the relocation of the outer seal connector on the two fasteners.

(26) the ease of disassembly of the seal assembly, by loosening the outer seal connector, makes for ease in maintenance. The ability to readily change any part of the seal assembly over the years, makes for an extended life of the seal assembly installed on any given tree.

(27) FIG. 14 shows the new seal assembly invention installed as part of a rain guard on a rubber tree.
