Abstract

An anchor, stay or peg which, once inserted into the ground, produces a larger subsurface footprint than its entrance hole. The anchor may have an inner shaft E and an outer body D which may be plastic or steel. When an upward force is applied to the inner shaft it may slide or move relative to the outer body, causing sprung fingers G to deploy and protrude out from the body. Pushing the inner shaft downwards will re-sheath the fingers so that the anchor can be extracted. The anchor may have a bottom tip L which can be detached via a screw thread. The anchor may have pull hooks, loops or grips C to enable extraction.

Description

The Typhoon Anchor Peg (TAP)

Background

Most wound anchors, stakes or pegs are a straight or curved pole of various materials that are driven into the ground at an angle to brace structures via tethers, ropes or straps. They have the same diameter entrance point as their footprint in the ground.

These stakes rely on the angle when inserted to the structure and the suction of the ground to keep them secure. They are very ineffective in windy/severe weather, on loose or lightly compacted ground/surfaces and when directly in line with the tether securing the structure.

Statement of invention -

To overcome this failing the TAP has single or multiple sprung fingers that extend underground to create a subterranean/subsurface footprint area that the sprung fmgers pull-up against to secure the surface structure.

Advantages The TAP requires a greater kn force to remove it when deployed in the ground/subsurface bringing greater resilience to structures in all weather conditions. It also allows for structures to be erected and secured on weak/granular ground or surfaces. --

Introduction to Drawings

An example of the TAP (Not to scale) will now be described by referring to the Drawings TAPO1 and TAPO2: TAPO1 -Section through TAP.

A. Anchor point for fixing a tether from the TAP to the structure that can be fixed or interchangeable with different applications depending on use.

B. Screw-thread for connecting or changing anchor point (ref: A) -C. Pull hooks, loops or grips to enable extriction of the TAP.

Detailed Description

The Typhoon Anchor Peg (TAP) has been designed to increase the amount of kn force that is required to pull all other surface anchor, stake or peg out of the ground when attached to a structure. It can be used in all weathers and climates, especially in high wind and loose ground/surface conditions. It really comes into its own when used on soft, granular or un-compacted surfaces. The more force that is exerted on the TAP at the anchor point (TAPO1-A) that is attached to the inner shaft (TAPO1-E), the more it becomes stable in the surface. All other surface anchors, stakes or pegs are only mildly effective when used on compacted ground.

The TAP, with its single or multiple sprung finger(s) (TAPO1-G & TAPO2-B), can be manufactured to any size so as to accommodate the forces exerted on it by a particular structure. The outer body (TAPOI -D & TAPO2-C) will be made out of high impact plastic, steel or other durable material. The inner shaft (TAPO1E & TAPO2A) has sprung finger(s) (TAPOI-G & TAPO2-B) of various amounts and lengths attached to it (TAPO2-D), that are then inserted into the outer body (TAPO1-D & TAPO2-C). When an upward force is applied to the inner shaft (TAPO1-E & TAPO2-A) it is allowed to move a predetermined distance causing the spmng finger(s) (TAPO1-G & TAPO2-B) to protrude out. This gives the TAP a larger subsurface footprint than the entrance point, allowing it to be used at any angle to the structure including directly in-line with the tether. The TAP is removed by detaching the tether from the anchcr point (TAPO1-A) and pushing the inner shaft (TAPOI-E & TAPO2-A) downwards. This re-sheaths the sprung fingers (TAPOI-G & TAPO2-B), enabling extraction using the fingerpulls (TAPO1-C) on the outer body (TAPO1-D).

The anchor point (TAPO1-A) is interchangeable with different heads depending on the TAP's usage. This is done by unscrewing the anchor point (TAPO1-A) from the shaft (TAPO1-E)atpointB (TAPOI-B).

The bottom tip (TA P01 -L) of the outer body (TAPO 1 -D) is detachable via a screwed thread (TAPO 1-K) to allow cleaning and removal of any granular substance that may become trapped.

The inner shaft (TAPO1-E) is designed to sit within the outer body (TAPOI-D) in such a way that when in the insert position it is firmly abutted (TAPO1-J) to the base of the sheath (TAPO1-D) and tip (TAPO1-L).

Claims

Claims 1. An anchor, stay or peg that once inserted in the ground produces a larger subsurface footprint than the entrance hole.
2. It can be made to any size that is required by the structure that is to be secured (ref: Claims 1).
3. The extending sprung finger(s) can be manufactured to any length, size and number (ref: Claims 2) depending on the surface conditions and the requirements of the structure it is securing (ref: Claims 1 & 2).
4. The subterraneanlsubsurface footprint of the TAP becomes greater as more force is applied (ref: Claims I) to the anchor point via the shaft to the sprung fingers (ref: Claims 3) from the surface structure.
