Definitions

  • This invention relates to an anchoring device, and in particular, but not exclusively to an anchoring device suitable for use as a tent peg.
  • Anchoring devices generally of the form of pegs or stakes are required for a range of applications, for example to secure a tent, or to steady a tall structure.
  • anchoring devices such as stakes or ground anchors are used to support retaining walls, to provide winching points for vehicles or mooring points for boats.
  • the common requirement is to drive a peg or stake far enough into the ground to provide a sufficiently robust anchoring point.
  • a stake does not need to be driven as far into the ground when the ground is firm, however the firmness of the ground can make it difficult to drive the stake. And yet in soft ground, while it may be easier to drive the stake, the stake will need to be driven much further to provide any useful support.
  • stakes or pegs having screw threads or auger forms can be expensive to manufacture and they can be heavier than pegs having a simple straight shaft. In addition, they can require a high torque to be installed into the ground.
  • Anchoring devices that have screw threads or auger forms are not dissimilar to the auger style post hole borers which can be more effective at dislodging the soil than penetrating into it.
  • the invention may broadly be said to consist in an anchoring device having a shaft with a first end and a second end, the device being adapted at or adjacent the first end to allow it to be rotatably driven about a longitudinal axis of the shaft, and the device having at least one substantially flat blade connected to the shaft between the first end and the second end, or at the second end, the or each blade extending primarily from one side of the shaft only, and the or each blade being oriented within a plane that is at an acute angle to the longitudinal axis.
  • each blade is connected to the shaft between a mid point along the length of the shaft and the second end.
  • a part or an outer edge of the or each blade has a profile which is substantially circular in shape.
  • each blade is connected to the shaft at or adjacent a point at the radial centre of the substantially circular profile.
  • the or each blade is substantially in the shape of a semicircle.
  • the or each substantially semicircular shaped blade is attached to the shaft at a point on the blade at or adjacent a point at a radial centre of the substantially circular profile.
  • the or each blade is oriented within a plane that is at an angle in the range of forty five to eighty five degrees to the longitudinal axis.
  • each blade is oriented within a plane that is at an angle in the range of fifty to sixty degrees to the longitudinal axis.
  • the or each blade is oriented within a plane that is at an angle in the range of seventy to eighty degrees to the longitudinal axis.
  • the shaft has a substantially circular cross section.
  • the device further includes a tethering fitting.
  • the tethering fitting is rotatably connected to the anchoring device.
  • the tethering fitting includes a shaft portion which can be aligned substantially parallel with the shaft of the anchoring device.
  • the anchoring device is a tent peg.
  • the anchoring device is a ground anchor.
  • the invention may broadly be said to consist in a temporary dwelling incorporating at least one anchoring device substantially as specified herein.
  • the temporary dwelling is a tent or a marquee.
  • the invention may broadly be said to consist in a shelter or umbrella incorporating at least one anchoring device substantially as specified herein.
  • the invention may broadly be said to consist in a pole incorporating at least one anchoring device substantially as specified herein, for example the pole of a sporting apparatus.
  • the invention may broadly be said to consist in a ground anchor incorporating at least one anchoring device substantially as specified herein.
  • the invention may also broadly be said to consist in the parts, elements and features referred to or indicated in the specification of the application, individually or collectively, and any or all combinations of any two or more of the parts, elements or features, and where specific integers are mentioned herein which have known equivalents, such equivalents are incorporated herein as if they were individually set forth.

  • the device is adapted at or adjacent the first end (13) to allow it to be rotatably driven about a longitudinal axis (17) of the shaft (11).
  • the device (10) also has a substantially flat blade (19) that is connected to the shaft (11) between the first end (13) and the second end (15), or at the second end (15).

  • the anchoring device (10) is intended for uses such as a tent peg or a ground anchor.
  • the device (10) includes a bolt head (20) at the first end (13) which allows the device (10) to be rotated using a suitable wrench.
  • a powered or battery operated drill or screw driver fitted with a suitable socket can also be used.
  • the second end (15) can be pushed into the ground, until the blade (19) contacts the ground and then the device (10) can be rotated allowing the blade (19) to cut into the ground and to draw the device (10) into the ground. Since the blade (19) is at an angle (21) to the axis (17) of the device (10), the blade acts like a part of a screw thread or an auger to drive the device into or out of the ground.

  • the blade (19) extends primarily from one side of the shaft (1 1) only, and in this case the blade (19) is connected to the shaft (11) between a mid point (23) along the length of the shaft (1 1) and the second end (15).

  • the tethering fitting (29) includes a shaft portion (31) which can be aligned substantially parallel with the shaft (11) of the anchoring device (10).
  • the shaft portion (31) can be inserted though an eyelet in the flap of a tent, and can be driven into the ground when the device is being screwed into place, to securely hold the flap.

Abstract

L'invention concerne un dispositif d'ancrage, par exemple un piquet de tente, composé d'un arbre doté d'une première et d'une seconde extrémité. Le dispositif est adapté à la première extrémité ou à proximité de la première extrémité pour lui permettre d'être entraînée en rotation autour de l'axe longitudinal de l'arbre possédant par exemple une tête de forme hexagonale. Le dispositif est également doté d'au moins une lame sensiblement plate reliée à l'arbre entre la première et la deuxième extrémité ou à la seconde extrémité, la lame étant orientée dans un plan à angle aigu par rapport à l'axe longitudinal. Un tel dispositif peut être enfoncé dans le sol par rotation à l'aide d'une poignée ou d'un outil électrique, la lame plate agissant comme une tarière pour enfoncer le dispositif dans le sol.
