  • Patent number: 9651058
    Abstract: A T-shaped fan blade arm attachment is disclosed for securing ceiling fan blades to a rotor of a ceiling fan motor. The fan blade arms have T-shaped ends with an elastomeric ring disposed adjacent the T-shapes ends. A mounting bracket has mounting holes with opposed slots for receiving the T-shaped ends of the fan blade arms. The opposed slots are preferably aligned at an angle to the horizontal when mounted to a ceiling fan motor. The mounting bracket has a flat surface exteriorly disposed on the mounting bracket adjacent to respective ones of the mounting holes. The mounting bracket has two cams with lock grooves disposed on interior surfaces of the mounting bracket, adjacent to respective ones of the mounting holes. The T-shaped ends insert into the mounting holes and are rotated to guide the T-shaped ends of the fan blade arms into the lock grooves.

  • Patent number: 9482242
    Abstract: C-connect fasteners (24) are provided for securing ceiling fan blades (26) to mounting brackets (20). Protuberant members (32) extend from the mounting brackets (20), and have heads (72) and shanks (74) which fit through apertures (62) in the ceiling fan blades (26). The C-connect fasteners (24) have an upper surface (36), a lower surface (38), and a peripheral edge (40) extending between the upper and lower surfaces (36, 38). An C-shaped opening (46) is formed in the peripheral edge (40) for sliding around the shank (74) and wedging the C-connect fastener (24) between the head (72) of the protuberant member (32) and the upper surface of ceiling fan blade (26). Resilient tabs (52) are spaced about the peripheral edge (40) the C-connect fastener (24) and press the upper surface (36) of the C-connect fastener (24) into the head (72) of the protuberant member (32).

  • Patent number: 9282665
    Abstract: An illuminated doorbell chime system is disclosed having a chime coil and LED lights. A chime control circuit has a power supply unit, an LED driver and a chime driver. The power supply unit is connected to the LED lights and the chime coil. The LED driver is connected to the LED lights. The chime driver is connected to the chime coil. A door switch selectively applies power to the power supply unit. The LED driver has a bipolar junction transistor, a base Zener diode, and a voltage divider. The chime driver has a Mosfet transistor, a gate resistor, a gate capacitor, and a gate Zener diode. The LED driver and the chime driver are interconnected, with a cathode of the gate Zener diode connected to the collector of the bipolar junction transistor, and a cathode of the base Zener diode connected to the drain of the Mosfet transistor.

  • Patent number: 8033787
    Abstract: A ceiling fan (12) is suspended from a mounting bracket (40) by a down rod (32) and a canopy (42) is provided for concealing the mounting bracket (40). The canopy (42) has a lower end (52) with apertures (56, 58) for mounting the ceiling fan (12) directly to the canopy (42) in alternative mounting configurations. A cover (44) is provided for concealing the apertures (56, 58) in the canopy (42). The cover (44) has a collar (102) which extends through a down rod opening (54) in the canopy (42), and has a plurality of protuberances (104) which secure the cover (44) to the lower end (52) of the canopy (42) in a snap engagement. A lip portion (100) upwardly extends from the cover (44) to provide a spacer for locating the protuberances (104) adjacent to an upper side of the lower end (52) of the canopy (42).

  • Patent number: 7351037
    Abstract: A Y-connect fastener (210) is provided for firmly fastening ceiling fan blades (26) to mounting brackets (20). A plurality of protuberant members (32) extend upwardly from the mounting brackets (20), and have head portions (72) and shank portions (74) which fit through apertures (62) in the ceiling fan blades (26). The fastener (210) has an upper surface (214), a lower surface (216), and peripheral edge portions (220) extending between the upper and lower surfaces (214, 216). Openings (224, 226) are formed in the peripheral edge portions (220) in alignment for sliding the opening (226) over one of the shank portions (74), and then rotating the fastener (210) to twist the two openings (224) around two of the shank portions (74), pressing the fastener (210) between the head portions (72) of the protuberant members (32) and the upper surface of ceiling fan blade (26).
