Publication number: 20140047782Abstract: A ground anchor positively anchors an outdoor implement in place to the ground. The ground anchor comprises an arm defining opposed first and second ends of the arm. The first end is pivotably and directly connected to the implement such that the arm is pivotable with respect to the implement. A spike defines opposed first and second ends of the spike and is arcuate such that the spike is operatively concave with respect to the arm. The first end of the spike is pivotably connected to the second end of the arm such that the spike is rotatable about the second end of the arm. The second end of the spike is adapted to be manually imbedded into the ground at a right or an acute angle with respect to the arm to, thereby, positively anchor the implement in place to the ground with pretension.Type: ApplicationFiled: August 15, 2012Publication date: February 20, 2014Inventor: Ralph Fahler

Patent number: 7743886Abstract: Systems for stabilizing ladders are provided. A representative system incorporates a ladder stabilizing assembly that includes a mount, a frame and a spike. The mount is configured to attach to a ladder. The frame extends from the mount and is movable between a stowed position, in which the frame is located adjacent the ladder, and an un-stowed position, in which the frame extends outwardly from the ladder. The spike extends from the frame and is operative to be driven into the ground such that, when the frame is in the un-stowed position and the spike is driven into the ground, the ladder stabilizing assembly provides support to the ladder.Type: GrantFiled: June 15, 2006Date of Patent: June 29, 2010Inventors: Kuyler Barron Feemster, Jr., D.

Patent number: 6779316Abstract: The present invention generally provides an anchor for providing an attachment point on a surface. In one embodiment, the anchor includes a center shaft having a first member and a second member pivotally coupled thereto. The center shaft has an attachment end and a piercing end. The piecing end is driven through the surface allowing the first and second members to pass therethrough. Once through the surface, the first and second members rotate away from the center shaft to an open position, thus preventing the anchor from disengaging the roof. A collar may be slidably disposed on the center shaft. The collar may be slid against the surface to lock the members in the open position.Type: GrantFiled: January 31, 2001Date of Patent: August 24, 2004Inventor: Kenneth Carroll

Patent number: 6735911Abstract: A multi-legged ground-anchoring device is provided for securing objects to fixed points. The device comprises a central hub from which a plurality of legs extends. At the distal end of each respective leg is a foot for the receipt of a spike. The spikes may be driven into the ground at a predetermined angle as dictated by the angle of each foot. When physically connected to the object being secured, nay force acting on the central hub of the device initiates a rotational movement of the legs which forces the spikes to dig deeper into the soil and hold the device more firmly to the ground.Type: GrantFiled: February 28, 2003Date of Patent: May 18, 2004Inventor: Billy W. Alexander

Publication number: 20030221378Abstract: Tethering stakes of the nature intended to be pounded flush with or below ground level. Certain of the tethering stakes include a cap on the pounding end which is adapted for ease of placement and release of a tethering line. Accordingly, the tethering line can be removed from the stake when it is to be pounded into the ground and then engaged with the stake only when tethering is desired. Certain of the embodiments include caps having uniquely shaped apertures for securing the tethering line. Another includes an aperture in communication with an aperture in the stake such that a lead cable or the like may be moved out of the way when the stake is pounded into the ground and may be fully received within the stake when tethering is not desired. Another embodiment employs a coupler passing through an aperture directly beneath the pounding surface to facilitate ease of attachment and removal of the tethering line.Type: ApplicationFiled: June 3, 2002Publication date: December 4, 2003Inventor: John M. Krieger

Patent number: 6619307Abstract: A ground anchor, such as a tent peg, includes a channel-section, ground-penetrating base member, and a second member at or adjacent one end of the base member. The second member projects (or is capable of projecting) from the base member at an inclination thereto and is provided with an attachment point for a tether.Type: GrantFiled: June 5, 2001Date of Patent: September 16, 2003Inventor: Robert John Orr

Patent number: 6230449Abstract: A support attachment for a post for reinforcing posts and straightening leaning posts. The support attachment for a post includes a generally L-shaped angle member for coupling to the post towards the lower end of the post. A pair of first arms are coupled to a lower end of the angle member for coupling, and a pair of second arms are pivotally coupled to free ends of the first arms.Type: GrantFiled: June 17, 1999Date of Patent: May 15, 2001Inventor: William A. Colvin, Jr.

Patent number: 5255480Abstract: A ground anchor comprises a generally flat anchor plate folded into a U or V-shape against a resilient bias. The resilient bias may be inherent in the folded portions of the anchor plate, or may be provided by means of auxiliary or plate springs disposed between the folded portions. In the latter, a retaining pin may secure the folded portions together while driving the plate into the ground. A release arrangement shears the pin so that the plate springs open to resist subsequent extraction.Type: GrantFiled: August 15, 1991Date of Patent: October 26, 1993Assignee: Hydracor International, Inc.Inventor: Peter Alsop

Patent number: 4576521Abstract: A permanent mooring method and arrangement for embedding a permanent mooring device in the sea bottom calls for the lowering of the permanent mooring device into the sea until the bottom end contacts the sea bottom, the transmission of fluid under high pressure via a hollow tubular body of the permanent mooring device to a nozzle portion thereof so as to create a fluidized area in the sea bottom around the permanent mooring device and to wash the permanent mooring device into and beneath the sea bottom, followed by transmission of a cementitious substance via the hollow tubular body to the nozzle portion so as to fill the fluidized area in the sea bottom with the cementitious substance. The permanent mooring device is vibrated during transmission of the high-pressure fluid, transmission of the cementitious substance, or consolidation of the cementitious substance, or during any combination thereof to assist in the embedding process.Type: GrantFiled: December 30, 1983Date of Patent: March 18, 1986Inventor: Joseph Conrad

Patent number: 4079557Abstract: The present invention discloses a stay anchor and a method for driving it into the soil. The stay anchor includes a pair of cutting members pivoted with each other through a pair of connecting plates and each comprising an arcuately curved resisting plate and a stabilizing plate extended from the inner major surface of the resisting plate at right angles thereto. A driving device is also provided for engagement with the upper end of the stabilizing plate to exert the driving impacts thereto. When driven, the pair of cutting members are driven into the soil along a curved path due to the curved resisting plates and opened or angularly spaced apart from each other with the curved resisting plates bearing against the undisturbed soil so that excellent holding power may be developed.Type: GrantFiled: October 22, 1976Date of Patent: March 21, 1978Inventor: Hikoitsu Watanabe

Patent number: 4023314Abstract: An anchor for securing a mobile home or the like in position on the ground comprises a hollow tubular anchor post having locking arms pivotably mounted at a lower end thereof for movement from an entry position wherein the locking arms lie flat against the post to a locking position wherein the locking arms are pivoted downwardly and outwardly from the post. The anchor includes a fluid jet embedding mechanism comprising an inlet for pressurized water at the upper end of the hollow anchor post and an outlet for pressurized water at the lower end of the anchor post. The anchor is embedded in the ground by directing a stream of water under pressure down the interior of the tubular anchor post and directly against the ground beneath the anchor post. This displaces the ground below the anchor and causes the anchor to embed itself firmly into the ground.Type: GrantFiled: October 2, 1975Date of Patent: May 17, 1977Inventor: Donald L. Tanner
