Ceiling fan and mounting assembly for ceiling fan
Ceiling fans typically include a motor including a rotor and a stator, blades, a downrod, and a mounting assembly for suspending the fan from a structure. The mounting assembly includes fasteners and brackets to secure the ceiling fan to the structure. The bracket receiving the downrod is fastened to a plate that is secured to the ceiling.
1. A mounting assembly for mounting a ceiling fan assembly to a mount surface, the mounting assembly comprising:
a plate configured to be mounted to the mount surface;
a hanger bracket;
a set of elastomeric grommets, coupling the plate to the hanger bracket, wherein each of the set of elastomeric grommets comprises:
a spacer located between the plate and the mount surface, a stem extending between the plate and hanger bracket, and
at least one cap located beneath the hanger bracket.
2. The mounting assembly of claim 1 , wherein the plate further comprises a set of plate apertures that receive at least one of the set of elastomeric grommets.
3. The mounting assembly of claim 2 , wherein the hanger bracket further comprises a set of bracket apertures that receive at least one of the set of elastomeric grommets.
4. The mounting assembly of claim 3 , wherein a plate aperture in the set of plate apertures is larger than a bracket aperture in the set of bracket apertures.
5. The mounting assembly of claim 4 , wherein the plate aperture is oblong and the bracket aperture is circular.
6. The mounting assembly of claim 3 , wherein the stem has a stem width and the bracket aperture has a bracket aperture width, and the stem width is the same as the bracket aperture width.
7. The mounting assembly of claim 3 , wherein the set of elastomeric grommets comprises two or more elastomeric grommets.
8. The mounting assembly of claim 7 , wherein each of the set of grommets comprises a bridge between at least two caps.
9. The mounting assembly of claim 1 , wherein the set of elastomeric grommets comprises one or more of natural rubber, synthetic rubber, neoprene, polyisoprene, polybutadiene, silicone rubber, or a viscoelastic polymer.
10. A ceiling fan assembly comprising:
a ceiling fan;
a downrod having one end terminating in a hanger ball and another end affixed to the ceiling fan; and
a mounting plate and a hanger bracket secured together by a set of elastomeric grommets, with the hanger bracket retaining the hanger ball.
11. The ceiling fan assembly of claim 10 wherein the set of elastomeric grommets comprise a spacer confronting one of the mounting plate or hanger bracket, a cap confronting the other of the mounting plate or the hanger bracket, and a stem extending between the spacer and the cap.
12. The ceiling fan assembly of claim 11 wherein the other of the mounting plate or the hanger bracket comprises a set of openings corresponding to the set of elastomeric grommets, and the cap has a portion larger than at least one of the openings in the set of openings.
13. The ceiling fan assembly of claim 12 wherein the cap is deformable to pass through the at least one of the openings.
14. The ceiling fan assembly of claim 13 wherein the cap has a variable cross-sectional area.
15. The ceiling fan assembly of claim 13 wherein the spacer is larger than the at least one of the openings.
16. The ceiling fan assembly of claim 11 wherein the spacer confronts the mounting plate and the cap confronts the hanger bracket.
17. The ceiling fan assembly of claim 10 wherein the set of elastomeric grommets are arranged in pairs.
18. The ceiling fan assembly of claim 17 wherein at least two of the pairs are diametrically opposed.
19. The ceiling fan assembly of claim 10 wherein the mounting plate has a set of mounting plate apertures, the hanger bracket has a set of hanger bracket apertures, which are aligned with the set of mounting plate apertures to form pairs of aligned apertures, and at least one of the set of elastomeric grommets passes through one of the pairs of aligned apertures.
20. The ceiling fan assembly of claim 19 wherein at least one of the elastomeric grommets in the set of elastomeric grommets comprises a spacer and a cap, wherein the spacer confronts and is larger than one of the apertures of the pair and the cap confronts and is larger than the other of the apertures in the pair.
