Abstract: Easy to attach and detach blades for overhead ceiling fans. A first version has a ceiling fan blade with keyhole slots that fit over flat topped fasteners on a mounting arm. Pulling the blade away from the arm locks the slots to the fasteners. A second version is similar to the first and has a decorative bottom cover having snappable tapered protrusions which attach through the keyholes and into mateable through-holes in the mounting arm connection. The third version has a protruding end portion of the blade that fits into a slot in the mounting arm where spring loaded pistons press into grooves in the protrusion end portion of the blade. Latching handles allow users to manually move the pistons. A fourth version has a slot in the blade which fits about a mateable housing in the mounting arm where opposing spring loaded pistons press into interior wall grooves in the slot of the blade.
Abstract: Snappable wheel holders for environmental control units such as radiators, heaters, fans and air conditioners. Wheel holders can attach wheels to brackets located underneath the units by mateably attaching male protruding ends into female slots. Plastic triangular pieces can snap into openings to lock the wheel holders to the brackets. The brackets can be attached underneath the units by clamping U-bars with wing nuts.
Abstract: An air-exhausting apparatus, device, method of assembly and use for an attic and rooftop fan, which prevents water intrusion into the housing. The fan can include a tubular base having a bottom side mounted on a roof of a room, and an upper end portion converging toward a top side of the base. A coupling sleeve unit has a first coupling end portion sleeved fixedly on the base and cooperating with the base to define an annular draining passage therebetween, and a second coupling end portion opposite to the first coupling end portion. A fan unit is mounted in the coupling sleeve unit, and is operable so as to exhaust air outwardly of the room via air holes in the second coupling end portion of the coupling sleeve unit. A cover unit includes a cover body disposed on the second coupling end portion of the coupling sleeve unit, and a supporting frame interconnecting fixedly the cover body and the coupling sleeve unit. Wear and/or sound absorbers can also be included.
Abstract: Portable solar powered light sources, devices, apparatus, systems and methods of attaching and using the light source. The light sources can have a single small housing having an upper roof portion with an exposed solar cell, a photocell activator, and small housing. The housing can have two parts that pivot with one another so that a front end of the housing can be biased together by a spring, and the rear side having edges that are spaced apart. An operator can press the rear spaced apart edges together, to open the front end to slide about a support structure, such as an open umbrella fabric edge. The housing allows for the light source powered by batteries to be activated by the photocell during dark(night) conditions), with the light direction being adjustable underneath. During daylight, the solar cell receives sunlight to charge the batteries within the housing.

Abstract: Outdoor high velocity wall and pedestal mounted fans, devices, apparatus, systems and methods of operation. The fans can have water resistant motor housings with at most one rear wall located opening for allowing a power cord to pass therethrough. The switches and pull chains are connected to the fan only through the bottom of the motor housing. The bottom of the motor housing can have a drainage hole for allowing excess moisture to drain therefrom. The motor housing can be stainless steel. Additionally, the motor housing can have a powder coat finish on all parts to reduce corrosion. The motor can be an oversized inverted outdoor rated oscillating motor having improved gear mechanisms for big torques and reduces heat rise during fan operation. The fan can operate under hot and cold temperature extremes as well as during wet and dry environmental conditions.
