A reinforced junction box assembly includes: a polygonal open housing body with a top surface on one side and a plurality of side walls vertically formed along the periphery of the top surface; at least one pair of holding flanges each with a guide opening in the middle separately provided along an edge of two opposing sides of the open housing body structure; and at least one pair of mounting members each with a reinforced ridge and two mounting sides respectively fixed on an interior surface of the two opposing side walls against the holding flange. In addition, each of the mounting members includes a threaded bore in the reinforced ridge, which is aligned with the guide opening of the respective holding flange, and a plurality of screw holes in the mounting sides, which are used to fix the mounting members on the opposing side walls. Thereby, safe connections can be ensured all the time between the mounting members and a suspension load through the guide openings and the threaded bores.

An apparatus for connecting a downrod to a mounting assembly and a motor housing of a fan. The mounting assembly and the motor housing are capable of receiving a differently sized downrod. The apparatus comprises a pair of adapters. The adapters each have a first end that engages an end of the downrod; a second end that engages either the mounting assembly or the motor housing; and a hollow interior extending between said first and second ends. In one alternative embodiment, the first end receives the downrod and includes: a pair of aligned apertures; and an aperture disposed between the pair of aligned apertures. The second end is threaded and engages either the mounting assembly or the motor housing. The second end includes a pair of aligned apertures on opposite sides thereof. The apparatus also includes a pair of pins to insert through the aligned apertures and a pair of fasteners for securing the downrod within the adapter. In another alternative embodiment, the first end inserts within the downrod. The first end includes a pair of aligned apertures on opposite sides of the first end. The second end is threaded to engage either the mounting assembly or the motor housing. The second end includes: a pair of aligned apertures on opposite sides of the second end. The apparatus also includes a pair of pins for inserting through the aligned apertures to secure either the downrod or the motor housing to the adapter.

An apparatus for detachable connection of a ceiling fan motor housing to a ceiling mounting assembly. The ceiling fan downrod provides a standardized elongated tube that is connectable to a multitude of ceiling fan housings and assemblies, and provides a universal ground wire connection through a plurality of holes for electrical grounding of the apparatus. The downrod is an elongated tube with a hollow center, having a plurality of pairs of holes near each end of the downrod. Each open end of the downrod has a plurality of threads on the exterior surface of each end, the threads providing one connecting method to attach one end of the downrod to a ceiling mounting assembly, and the second end of the downrod to a motor housing of the ceiling fan. The downrod provides numerous options for connecting the downrod to ceiling fan assemblies, and provides versatility for attachment of electrical ground wires through the plurality of holes in the downrod.

An overhead support system for TV monitors comprising a shoe releasably and slidably insertable into seated position into a pocket in an upper portion of the monitor housing. The shoe carries electrical contacts to mateably engage with corresponding electrical contacts for the monitor when in seated position. Conductor cables are embedded in the shoe and extend from the electrical contacts through a pipe, one end of which is secured to the shoe and the other end of which passes through shock absorbing material supported on an overhead support frame to threadably engage an anchor means supported on the shock absorbing material. This system securely supports such monitors in overhead locations such as on buses.

A method and an apparatus for functional testing of a suspension device for a load, is used in combination with a suspension device such as a spring hanger or a constant support hanger holding a pipe run on a building structure and having at least one mechanical spring. The load is released from the suspension device and held with other devices. A hydraulic device is connected to the suspension device to be tested instead of the load for stretching the spring of the suspension device. The pressure necessary for stretching the spring and therefore the spring constant of the spring based on the operating travel of the spring, are ascertained and recorded with a pressure pickup and a recorder connected to the hydraulic device.
