Abstract

A ceiling fan comprising a motor system. The motor system is mounted around a motor shaft. The motor shaft couples to a downrod for suspending the ceiling fan from a structure. The motor shaft and motor are encased by a motor housing. The motor housing comprises hub arms for mounting a plurality of blade holders. The blade holders coupled to a plurality of blades rotatable about the motor during operation. The downrod comprises a wire disk mounting guy wiring to the downrod. A retention rod is utilized internal of the motor and downrod as a secondary retention method. An electrical connector is internal of the motor shaft and electrically couples to the stator to power the motor.

First claim

What is claimed is:

1. A ceiling fan comprising:
a set of blades;
a set of blade holders adapted to couple to the set of blades and at least a portion of each of the set of blade holders having a rounded profile; and
a motor assembly including a rotating hub having a set of blade mounts defining a blade mount cavity and adapted to receive the set of blade holders at the portion having the rounded profile, the set of blade mounts comprising:
at least one aperture extending through the set of blade mounts in communication with the blade mount cavity; and
at least one saddle provided in the at least one aperture and having a curved surface configured to abut the rounded profile of the set of blade holders and adapted to secure the set of blade holders within the blade mount cavity at the rounded profile.

2. The ceiling fan of claim 1 further comprising at least one fastener aperture provided in at least one of the set of blade mounts and in communication with the blade mount cavity.

3. The ceiling fan of claim 2 wherein the at least one saddle is slidable along the at least one fastener aperture to reduce the effective cross-sectional area of the blade mount cavity.

4. The ceiling fan of claim 3 wherein the at least one fastener aperture is oriented at an angle relative to a horizontal plane.

5. The ceiling fan of claim 4 wherein the angle is 20 degrees.

6. The ceiling fan of claim 5 wherein the at least one saddle is adapted to anchor a blade holder within the at least one of the set of blade mounts along a radial extension of the at least one fastener aperture relative to the blade mount cavity.

7. The ceiling fan of claim 2 wherein the at least one fastener aperture includes two fastener apertures and the at least one saddle includes two saddles.

8. The ceiling fan of claim 1 wherein at least one of the set of blade mounts comprises multiple blade mounts radially spaced about the rotating hub.

9. The ceiling fan of claim 8 wherein the at least one of the set of blade mounts includes five blade mounts.

10. The ceiling fan of claim 1 further comprising at least one fastener operably coupled to the at least one saddle to move the at least one saddle into the blade mount cavity.

11. The ceiling fan of claim 10 wherein the at least one fastener is a set screw actuable to threadably tighten the at least one saddle against at least one of the set of blade holders.

12. The ceiling fan of claim 1 wherein at least one of the set of blade mounts further includes at least one pin aperture.

13. The ceiling fan of claim 12 the at least one of the set of blade mounts further comprises an inlet, with a channel extending from the inlet to the pin aperture.

14. The ceiling fan of claim 13 wherein the at least one saddle is aligned along the channel.

15. The ceiling fan of claim 14 further comprising a plurality of blades and at least one blade holder adapted to mount the plurality of blades to the rotating hub at the at least one of the set of blade mounts.

16. The ceiling fan of claim 15 wherein the at least one blade holder includes a depressible pin adapted to releasably lock the at least one blade holder within the at least one of the set of blade mounts at the pin aperture.

17. The ceiling fan of claim 16 wherein the motor assembly further includes a non-rotating motor shaft about which the rotating hub rotates.

18. The ceiling fan of claim 17 further comprising a shaft coupler and a downrod plate adapted to couple the non-rotating motor shaft to a downrod.

19. A ceiling fan comprising:
a set of blades;
a set of blade holders including an actuable pin adapted to couple to the set of blades and at least a portion of each of the set of blade holders having a rounded profile;
a motor assembly including a rotating hub having a set of blade mounts defining a blade mount cavity and adapted to receive the set of blade holders at the portion having the rounded profile, the set of blade mounts comprising:
at least one pin aperture extending through the set of blade mounts in communication with the blade mount cavity configured to couple the set of blade holders within the blade mount cavity with the actuable pin;
at least one aperture extending through the set of blade mounts in communication with the blade mount cavity;
at least one saddle provided in the at least one aperture and having a curved surface configured to abut the rounded profile of the set of blade holders and adapted to secure the blade holder within the blade mount cavity at the rounded profile; and
at least one fastener coupled to the at least one saddle configured to selectively tighten or loosen the at least one saddle against the set of blade holders within the set of blade mounts.
