A threaded fastener pair, including: a first threaded fastener with a male threaded portion; and a second threaded fastener with a female threaded portion, the female portion being configured to receive the male threaded portion, wherein the first threaded fastener is formed with a shank having an outer diameter approximately equal to an outer diameter of the second threaded portion, the second threaded fastener has a length equal to or greater than that of the first threaded fastener and the length of the first threaded fastener is at least 45 mm.

A cylindrical two-piece pole stand assembly that automatically locks together upon insertion of a pole is disclosed which has a permanently set in-ground sleeve base formed of a length of tubing with a top end and a bottom end. A crowd control and umbrella stanchion made from a length of tubing has an outside surface with a diameter that allows for a sliding fit into or onto the sleeve. The crowd control and umbrella stanchion includes a locking mechanism for locking the crowd control and umbrella stanchion to the sleeve base. The crowd control and umbrella stanchion has a pair of upper loops welded on opposite sides of an upper portion of the crowd control and umbrella stanchion which provides a single stanchion upright which allows for the attachment of crowd control ropes or chains and also provides for the insertion of an umbrella pole to allow for an umbrella to be secured in the same location as said stanchion uprights.

A holder for a pole of a basketball hoop system includes a pole sleeve for receiving the pole, a tightening system for securing the pole into the pole sleeve in a solidary relationship, and a mounting bracket to secure the pole sleeve to a ground directly or via a stake. The pole holder includes a first mounting element defining a first mounting surface for securing the mounting bracket to the ground in a generally parallel relationship, and a second mounting element that is fixedly mountable to the first mounting element and that defines a second mounting surface for fixedly receiving the pole sleeve in a generally parallel relationship, such that the pole sleeve is offset from the first mounting surface. The first and second mounting elements can be assembled within a first range of relative angular positions therebetween about a first axis that is generally parallel to the first mounting surface, and the pole sleeve and second mounting element can be assembled within a second range of relative angular positions therebetween about a third axis that is generally perpendicular to the second mounting surface and to the second axis.

A two-piece pole holder includes an insert and a base. The insert is embedded within soil or concrete. The base is threadingly connected to the top of the insert to form the pole holder. The insert has a solid bottom end for receiving a pole. The bottom end of the insert can also include a drain opening for allowing water to drain. The pole can be an outdoor umbrella pole or volleyball net poles. The inner diameter and height of the insert and the base are selected such that improved stability is provided to the pole such that the pole does not tip over in strong winds. The pole holder can be installed in a water feature, such as a swimming pool.

Introduced here is an umbrella stand capable of securely holding umbrellas of various sizes, shapes, and weights. The umbrella stand includes a base and a holder portion. The base includes mechanisms to secure the umbrella stand to a surface such as ground spikes or suction cups. The holder portion is connected to the base via abutments that protrude up from the periphery of the base. The holder portion and the base are separated by a gap. The holder portion includes tightening mechanisms and a door. The tightening mechanisms help securely hold an umbrella handle or shaft and can adjust the angle at which the umbrella is held. The door, in combination with the gap, allow a user to use the umbrella stand with umbrellas with handles of various shapes and sizes.

A beach umbrella anchoring and stabilizing device includes a support shaft having a proximal end, a distal end, and a hollow interior for receiving a beach umbrella. An anchoring container affixed to the support shaft includes an open top, a closed bottom, and a sidewall extending around the support shaft from the open top to the closed bottom. The sidewall defines a laterally extending reservoir for receiving sand to anchor the device underneath the beach surface and provide lateral support to a beach umbrella mounted into the support shaft. Stabilizing vanes protrude from the distal end of the support shaft and extend from the closed bottom to the distal end. Each of the stabilizing vanes defines a broad surface that engages sand when a rotational force is exerted onto the support shaft, thereby preventing rotation of the support shaft about a longitudinal axis thereof when buried under the sand.

A fence post mount device comprising: a base having at least one cavity; a first universal collet having a plurality of collet legs attached to each other through at least one of a plurality of separation notches, wherein a distal end of the first universal collet is inserted into the cavity from a proximal end of the base; a first cap nut inserted into the first universal collet; a post inserted into the cavity of the base; a full thread nut threaded into the first cap nut from a distal end of the base through an opening, wherein each of the plurality of separation notches are broken when the full thread nut is tightened into the first cap nut and each of the collet legs of the first universal collet deforms an inner wall of the post such that the post is securely locked within the cavity of the base.

A garden stake includes a top portion that includes an elongate parallelepiped body having an open top and a closed bottom. The body has a central longitudinal axis extending therethrough. A flange extends outwardly from the closed bottom. A bottom portion includes a spike extending from the flange, away from the body.

A foundation for a wind power plant includes a circular or polygonal pedestal divided into several ring sections for carrying a tower and support elements extending radially outward from the pedestal, wherein the ring sections and the support elements are designed as prefabricated concrete elements or are assembled from prefabricated concrete elements, and wherein adjacent support elements are spaced from one another in the circumferential direction, adjacent support elements are each connected with one another by a tangentially extending beam designed as a prefabricated concrete element.

An offshore wind energy system comprising a foundation having a first hollow structural element with a longitudinally extending, circumferential first wall. A cable bushing penetrates through the first wall and is arranged in the first wall. At least one cable guide arrangement extends in a radial direction and is arranged at an outer shell surface of the first wall of the first hollow structural element. The cable guide arrangement is configured to guide a submarine cable exiting the cable bushing from the cable bushing to a submarine bottom surface.
