A cable securing device for installing and removing cable or wire through a wall. The cable securing device includes a rod having a first rod section, a second rod section, and a fastener disposed on each end capable of securing a cable thereto. The first rod section is movably secured to the second rod section in order to allow a user to independently rotate each end when installing cable to one of the fasteners. In operation of one embodiment, the user secures a new cable to a first threaded fastener and an old cable to a second threaded fastener. The rod sections are attached to each other if they had not been previously attached, and the new cable is threaded into the wall and old cable is removed from the wall through a single action by the user.

A pipe support system includes a base having a collar, and an extension assembly that includes a threaded member having a first end and a second end. The first end has a leg configured to be received by the collar such that the extension assembly is supported by the base, and the second end has a tube with exterior threads. The extension assembly also includes a nut member having corresponding interior threads. The pipe support system also includes a support having an arm configured to be received within the tube and a head extending from one end of the arm. The support rests on the nut member such that upon rotation of the nut member, the head either raises or lowers with respect to the base.

A connector includes a cube, a first cylinder and a second cylinder. The cube includes first, second, third, fourth, fifth and sixth faces. The cube includes a first bore therein, the first bore having a first longitudinal axis. The first cylinder extends from the first face; the first cylinder includes a first hole therein, the first hole having a second longitudinal axis. The second cylinder extends from the second face; the second cylinder includes a second hole therein, the second hole having a third longitudinal axis. The first, second and third longitudinal axes are parallel to each other. In another aspect, a vent element includes a first piece and a second piece that is a mirror image of the first piece, each of the pieces having upper, middle and lower portions. In yet another aspect, a system is configured for removable attachment of an elongated tube to a surface.

A joint assembly for joining structural members in a building frame can comprise: a marriage strap including one or more through-holes; one or more fasteners configured to be inserted through the one or more through-holes of the marriage strap; and a cube coupling joint including one or more recessed channels sized and shaped to receive a portion of the marriage strap, one or more fastener holes located within the one or more recessed channels and configured to receive and secure to the one or more fasteners. In some embodiments, the marriage strap is configured to be inserted into the one or more recessed channels of the cube coupling joint and the one or more fasteners are further configured to be inserted into and secured to the one or more fastener holes of the cube coupling joint.

A joint comprising: a tenon, a mortise for receiving the tenon, an aperture formed in one of the tenon and an interior wall of the mortise and a pin which extends from the other of the tenon and the interior wall of the mortise; wherein the aperture is a hole which is engaged by the pin in use such that the tenon is supported within the aperture, and the tenon is capable of vertical and horizontal motion within the mortise in a plane substantially orthogonal to a longitudinal axis of the pin, the motion being limited by the edges of the aperture

A structure with hollow or partially hollow structural elements for shade structures, such as gazebos, sunshades, beach umbrellas or covering structures in general, or adapted to be used for furniture, includes a plurality of hollow or partially hollow structural elements and a system of joints configured to join the structural elements to one another.

Aspects of the disclosure provide a non-welded, clevis-type coupling assembly that provides two sheer planes and, accordingly, increases the load bearing capacity thereof. The assembly includes a coupling plate having a first section, a second section, and a third section. The second section is intermediate the first section and the third section and the first and third sections are oriented at an angle of 90 with respect to one another. The coupling plate includes a contiguous opening extending there through having a first part and a second part. The first part has a first dimension and the second part has a second dimension that is larger than the first dimension.

A keyed and indexed tube and a taper lock system are suitable for use with a wheelchair, especially a pediatric wheelchair, which may require frequent adjustments during the growth of the occupant.

A flight device includes a device body with a surface, a plurality of arm structures disposed in the device body and a plurality of rotor modules disposed to the arm structures respectively. Each arm structure includes a fixing base, a second screw element, a connecting unit, a rod body and a position-limiting element. The fixing base is disposed in the device body and includes a first screw element having a first screw part. The second screw element has a second screw part matched with the first screw part. The connecting unit drills through the second screw element. The connecting unit is locked to the fixing base by screwing the first and second screw parts with each other. The rod body drills through the connecting unit. The position-limiting element is disposed between the second screw element and the connecting unit. The position-limiting element abuts against the second screw element.
