Quick connect ceiling fan blade
View Patent ↗A ceiling fan ( 10 ) is disclosed having a motor housing ( 11 ) with an electric motor to which is mounted an annular array of blade irons ( 14 ) each having a blade ( 15 ) mounted thereto. Each blade has two, catch mounting holes ( 17 ) and a fastener mounting hole ( 18 ) extending therethrough. Each blade iron ( 14 ) has a blade mounting portion ( 23 ) and a removable blade fastener ( 24 ). The blade mounting portion ( 23 ) has a top surface ( 26 ), two stationary mounting catches ( 27 ), and a fastener receiver ( 28 ) that is configured to receive fastener ( 24 ). Each catch has a generally vertical portion ( 31 ) and a top, horizontal portion ( 32 ) The horizontal portion ( 32 ) is spaced a select distance from the top surface ( 26 ) through the height of the vertical portion ( 31 ) so as to catch snugly the blade ( 15 ) therebetween. The fastener ( 24 ) extends through the fastener mounting hole 18 and into the fastener receiver ( 28 ). The blade may be mounted to the blade iron by passing the catches through the catch mounting holes, sliding the blade outboard and then passing the fastener through the fastener mounting holes of the blade and into the fastener receiver in the blade iron.
1. A ceiling fan comprising,
an electric motor;
an annular array of blade irons mounted to said motor, each said blade iron having at least one catch and at least one fastener receiver;
a ceiling fan blade associated with each said blade iron of said annular array of blade irons, each said blade having at least one catch mounting hole and at least one fastener mounting hole; and
a rotatable fastener having a stop portion configured to abut a fan blade surface opposite said blade iron and having a hand gripping portion, and a locking portion configured to extend through said blade fastener mounting hole and be releasably received within said fastener receiver, said rotatable fastener being rotatable between a locked position locking said blade to said blade iron and an unlocked position unlocking said blade from said blade iron,
whereby each respective blade may be mounted to each respective blade iron by passing the catch through the fan blade catch mounting hole and then passing the fastener through the fan blade fastener mounting hole and into locking engagement with the blade iron fastener receiver, and whereby an operator may grasp and operate the fastener.
2. The ceiling fan of claim 1 wherein said catch has a vertical portion extending through said catch mounting hole and a flange portion extending from said vertical portion in a position to overlay said fan blade surface opposite the blade iron.
3. The ceiling fan of claim 2 wherein said flange portion extends towards said fastener.
4. A ceiling fan comprising,
an electric motor;
an annular array of blade irons mounted to said motor, each said blade iron having at least one catch;
a ceiling fan blade associated with each said blade iron of said annular array of blade irons, each said blade having at least one catch mounting hole and at least one fastener mounting hole; and
a rotatable fastener adapted to partially extend through said fastener mounting hole and to be coupled to each said blade iron to releasably lock each said ceiling fan blade to one said blade iron, said fastener having a stop portion configured to abut a fan blade surface opposite said blade iron, a hand gripping portion and a locking portion configured to extend between said stop portion and said blade iron through said blade fastener mounting hole, said rotatable fastener being rotatable between a locked position locking said blade to said blade iron and an unlocked position unlocking said blade from said blade iron,
whereby each respective blade may be mounted to each respective blade iron by passing the catch through the fan blade catch mounting hole and then locking the fastener to the blade iron.
5. The ceiling fan of claim 4 wherein said catch has a vertical portion extending through said catch mounting hole and a flange portion extending from said vertical portion in a position to overlay said fan blade surface opposite the blade iron.
6. The ceiling fan of claim 5 wherein said flange portion extends towards said fastener.
7. A ceiling fan comprising,
an electric motor;
an annular array of blade irons mounted to said motor, each said blade iron having at least one catch;
a ceiling fan blade associated with each said blade iron of said annular array of blade irons, each said blade having at least one catch mounting hole and a fastener mounting hole therethrough, and
a fastener associated with each said blade iron, each fastener having a first portion coupled to said blade iron and a second portion adapted to mate with said first portion to releasably lock one said blade to one said blade iron, said fastener having a stop portion configured to abut a fan blade surface opposite said blade iron and having a hand gripping portion, and a locking portion configured to extend between said stop portion and said blade iron through said blade fastener mounting hole, said fastener being rotatable between a locked position locking said blade to said blade iron and an unlocked position unlocking said blade from said blade iron.
8. A The ceiling fan of claim 7 wherein said catch has a vertical portion extending through said catch mounting hole and a flange portion extending from said vertical portion in a position to overlay said fan blade surface opposite the blade iron.
