A support assembly and methods relating thereto is disclosed for supporting a pipeline at a height above the ground. In an embodiment, the support assembly has a central axis and includes a vertical pile assembly configured to be coupled to the ground. In addition, the support assembly includes an upper support member coupled to the vertical pile assembly. The upper support member includes a support surface that is configured to support one or more pipelines. The vertical pile assembly is configured to transition between a retracted position, wherein the support surface is disposed at a height H1 measured axially from the ground, and an extended position, wherein the support surface is disposed at a height H2 measured axially from the ground that is greater than the height H1.

Disclosed is an antenna clamping device, which includes: an arm unit which is coupled to a support pole and is partly provided to be movable in a horizontal direction; a coupling unit that is detachably mounted on a part of a tip of the arm unit; a rotation unit whose tip portion is coupled to the coupling unit so as to be ratable at a predetermined angle in a left-right direction; and a tilting unit that is coupled. to a tip portion of the rotation unit so as to be tiltable in a top-down direction and mediates coupling of an antenna device, wherein an angular motion adjuster is provided on at least any one of the rotation unit and the tilting unit so as to adjust a rotating angle, thereby removing spatial limitations on a plurality of antenna devices with respect to the support pole and improving workability.

An adjustable bathroom handrail assembly is provided with a pair of elongate vertical handles with mounting hardware to mount to an upright support surface and spaced apart from the upright support surface. An adjustable horizontal bar extends between the pair of vertical handles, and a locking mechanism connects the at least one adjustable horizontal bar and one of the pair of elongate vertical handles. A locking mechanism is located at an intersection of the horizontal bar and the one of the elongate vertical handles. A method for installing and adjusting wall-mount hardware installs a pair of elongate vertical handles to an upright support surface. The ends of a horizontal bar are installed onto the pair of elongate vertical handles. A locking mechanism on the horizontal bar is disengaged to adjust the horizontal bar to a location along the pair of elongate vertical handles.

A linking arm assembly adapted to receive and retain a ball stud. The assembly includes an elongated rod structure and a socket head and is variable over a range of lengths by adjustment of the relative position of the elongated rod structure and the socket head. Linking arm assemblies consistent with the present disclosure may be adjusted for use in different applications while using common components.

A rotation-adjustable hanging device includes a pivot seat, a hanging arm body and a limiting unit. The hanging arm body includes a pivot end connected pivotally to the pivot seat about a first pivot axis. The limiting unit includes a main body, two limiting arms and two limit ends. The main body is disposed on the pivot seat and defines a second axis. The limiting arms are directed toward the pivot end to extend the limit ends to the arm body such that the limit ends are disposed at two opposite sides of a first line that passes through the first and second pivot axes and such that the limit ends is able to stop rotation of the arm body.

Systems and methods for adjustable telescopic support rods are provided. Specifically, the telescopic support rods in accordance with some embodiments comprise selectably modifiable indexed lengths having no externally visible indication of the indexing means. Methods for modulating the length of the support rod and its use in, for example, vertical support for scaffolding and shelving units are also provided.

A power tool is provided with a telescopic pole including a first pole configured to telescopingly move in an out of a second pole. A locking mechanism is provided including a first section configured to connect to the second pole and a second section configured to connect to the first pole. The first section includes a sheaf mountable on and surrounding at least part of the second pole, a resilient tab connected to the sheaf, and a catch formed on the tab. The catch is configured to locate within the recess of the second pole when the sheaf is mounted on the second pole.

An autonomous mobile device (AMD) includes a telescoping mast with sensors on top that are connected to a cable running through the mast. An inner section of the mast includes a bobbin that secures cables. The bobbin has a shaft and features that guide cables to helically wind around the shaft. The bobbin reduces stress on the cable as the mast moves. The mast is lifted by a rack that includes a portion with teeth and a portion without. The portion with teeth is driven by a motor. The portion without teeth connects the rack to a spool. The toothless section reduces stress on the toothed portion of the rack as it spools or unspools. The AMD includes a hinge to tilt a display. To securely position the hinge on a shaft, the shaft is spun after assembly so that a push nut cuts a retention groove in the shaft.

A wheelchair push handle assembly incorporating a chair back having right and left loops, and an upper end; right and left upwardly opening tubes respectively received within the right and left loops; right and left eyes opening the right and left tubes, wherein the eyes overlie the chair back's loops; right and left “L” members having hollow bored columns within the right and left tubes; right and left series of apertures opening the right and left columns' hollow bores; right and left series of latch pins received within the right and left series of apertures; and right and left series of springs mounted within the right and left columns' hollow bores, wherein each spring is connected to one of the latch pins, wherein one of the right latch pins engages the right eye, and wherein one of the left latch pins engages the left eye.

A telescopic device includes a first shaft telescopically coupled to a second shaft. The first shaft defines a hole and an orifice. The second shaft defines a plurality of engaging portions. The second shaft inserts in the hole. The second shaft is movable with respect to the first shaft to a position in which one of the plurality of engaging portions is aligned with the orifice. A positioning device is coupled to the first and the second shafts. The positioning device includes a control being movable and a fastener being movable actuated by the control. The fastener is movable with respect to the control. The fastener inserts and is movable in the orifice. The first shaft is adapted to be unmovably positioned with respect to the second shaft at various positions by the positioning device.
