A swingset has a swingset frame. A horizontal member has a first horizontal section, and a second horizontal section. The first horizontal section has a swaged connection to the second horizontal section. The first horizontal section and the second horizontal section are formed of tube metal. A first horizontal section swaged portion fits within the second horizontal section. A pair of first legs support the first horizontal section, and a pair of second legs support the second horizontal section. The pair of first legs engage to a pair of first leg sockets formed on the first horizontal section. The pair of second legs engage to second leg sockets formed on the second horizontal section. A swing is suspended from the horizontal member. A lower tension bracket is mounted on a lower wall of the first horizontal section.

The present invention relates to a modular system of construction, conduction and fixation of tubular structure elements, comprising a first module (200), a second module (300) and, optionally, one or more additional modules (n), wherein each module (200, 300, n) comprises, in the region of its upper end, an annular fixing flange (230, 330) and crimp fins (240, 340) arranged inside the upper end at a fin distance (P.sub.240) which is equivalent to a crimping depth (P.sub.200, P.sub.300) decreased from 10 to 100 millimeters, preferably from 50 millimeters. The crimping depth (P.sub.200, P.sub.300), in turn, corresponds to a value between 0.5 and 3, preferably 1.5, times the diameter measurement (D.sub.200, D.sub.300) of the corresponding module (200, 300). The present invention also relates to a corresponding tubular structure (150).

At least one twelve-different-application rotatable and pivotable umbrella each comprises: at least one pivotable pole receiver each having: a pole-centering sleeve and receiver gears; a rotatable adjustor having: adjustor gears for engaging to the receiver gears and bottom gears; a trailer-hitch-adapting tube for engaging to a trailer hitch; at least one curved-surface-adapting plate each releasably attached to the trailer-hitch-adapting tube; a spiral-shovel spike having: a spiral blade and digging shovels for securely burying the spiral blade in soil and sand; a base attached to the trailer-hitch-adapting tube or the spiral-shovel spike, and having: base gears for engaging to the bottom gears, two wrenching-and-strapping handles for wrenching and strapping the base, and a surface-conforming-and-protecting adaptor attached thereto; at least one base-securing strap and ratchet for attaching the base to bumper, bench, table, hand rail, post, column, tree, tail gate, e.i.; and at least one adjustable umbrella each having: a canopy and a pole for being inserted through the pole-centering sleeve and into one of the at least one pivotable pole receiver.

Systems and methods for joining together two or more in-line components such as rail (e.g. staircase rail) components or like structures are disclosed herein. The system includes two or more components, each having at least one spring-bolt attached thereto and received in a respective cavity of the components. The components are coupled to one another by interlocking of the spring bolts caused by relative rotation of the spring-bolts, and the components include inner and outer perimeters sized to form a substantially flush connection with no external signs of the coupling mechanism when the components are so coupled.

A cover band has a cover band body provided with a cover band arch portion corresponding to the outer peripheral surface of a steel pipe strut and a plurality of cover band through holes formed on the cover band body in such a manner as to correspond to a plurality of strut coupling holes. The cover band through holes have shapes of long holes extended in one direction and the extended direction of at least one of the cover band through holes is made to cross the extended direction of the other cover band through hole.

A connection between a first tubular member and a second tubular member includes a first tubular end, a second tubular end, a load shoulder member threadable onto the first tubular end, and a nut receivable around the first tubular end and the load shoulder member and threadable onto the second tubular end. The connection also includes a keyway through the load shoulder member and into the first tubular end to receive a key member.

A wing nut may include a body having a first part extending from a first end surface to a parting line and a second part extending from the parting line to a second end surface. A passage may axially extend through the body, the passage defining an interior surface of the body. An internal threaded section may be formed on an interior surface of the first part. An internal shoulder may be formed on the interior surface of the second part. A stress relief may be formed on the interior surface of the second part between the internal shoulder and the parting line. A rib may extend inward from the interior surface of the second part, the rib being intermediate the stress relief and the internal threaded section. At least one lug may extend radially from the exterior surface of the body.

A method for installing a wedge connector positioned between two conductive cables includes connecting a head coupler portion of a disconnect assembly to a wedge frame, wherein the head coupler portion includes an extension rod within a longitudinal bore; positioning the wedge frame and a first end of the extension rod against the wedge connector; connecting the head coupler portion to a tool coupler portion of the disconnect assembly, wherein the tool coupler portion is connected to a hydraulic drive tool that includes a ram; causing the hydraulic drive tool to apply force to a second end of the extension rod, wherein applying the force to the second end causes the first end to apply force to the wedge connector; and disconnecting the head coupler portion from the tool coupler portion.
