Abstract

A canopy assembly includes a bracket, a canopy, a plurality of screws, two biasing members and an annular decorative ring. The canopy has two locking sections and two installation sections. Each of the installation sections has a limit wall and an abutment wall connected to the limit wall and cooperating with the limit wall to define an installation groove. Each of the biasing members includes an elastic plate engaging a respective one of the installation grooves and a protrusion formed on the elastic plate. The annular decorative ring covers the screws and has two engaging segments. Each of the engaging segments is formed with a groove engaged with the protrusion of a respective one of the biasing members.

Claims

1. A canopy assembly adapted for use in a ceiling fan, said canopy assembly comprising:

a bracket;

a canopy surrounding said bracket and having an upper end portion that has two locking sections and two installation sections interconnecting said locking sections, said locking sections and said installation sections being alternately arranged, each of said installation sections having a limit wall and an abutment wall that is connected to said limit wall and that cooperates with said limit wall to define an installation groove;

a plurality of screws securing threadedly said locking sections of said canopy to said bracket and each having a head that is exposed from said locking sections of said canopy;

two biasing members attached respectively on said installation sections of said canopy, each of said biasing members including an elastic plate that engages said installation groove of the respective one of said installation sections, and at least one protrusion that is formed on said elastic plate and that is exposed from the respective one of said installation sections; and

an annular decorative ring surrounding said upper end portion of said canopy, covering said head of each of said screws and said biasing members, and having two engaging segments that are registered respectively with said installation sections of said upper end portion of said canopy, each of said engaging segments being formed with a groove that is engaged with said protrusion of a respective one of said biasing members.

2. The canopy assembly as claimed in claim 1, wherein:

said abutment wall of each of said installation sections has a bottom wall segment extending inwardly from said limit wall, and an abutment wall segment bent from a distal end of said bottom wall segment;

said installation groove of each of said installation sections has an upper opening opposite to said bottom wall segment and opposite lateral openings in spatial communication with said upper opening;

said elastic plate of each of said biasing members is inserted into said installation groove of the respective one of said installation sections through said upper opening of said installation groove, and has a main portion supported by said abutment wall of the respective one of said installation sections, and two extending portions extending from said main portion and respectively through said lateral openings of said installation groove; and

each of said biasing members includes two of said protrusions that are formed respectively on said extending portions of said elastic plate.

3. The canopy assembly as claimed in claim 2, wherein:

said limit wall of each of said installation sections is formed with two through holes; and

said protrusions of each of said biasing members are biased by a radially-outward resilient force of said elastic plate of said biasing member to engage firmly and respectively said through holes of said limit wall of the respective one of said installation sections.

4. The canopy assembly as claimed in claim 1, wherein said groove of each of said engaging segments extends parallel to a periphery of said annular decorative ring.

5. The canopy assembly as claimed in claim 4, wherein said annular decorative ring further has two covering segments registered respectively with said locking sections of said canopy and interconnecting said engaging segments, said covering segments and said engaging segments being alternately arranged, each of said covering segments having an inner surrounding surface that is disposed at a radially-outward position relative to that of said engaging segments, that cooperates with said engaging segments and a respective one of said locking sections of said canopy to define a receiving space accommodating said head of each of said screws which are located on the respective one of said locking sections, and that has an arc length greater than a distance along an outer surface of the respective one of said locking sections between two opposite outermost ones of said screws which are located on the respective one of said locking sections.

6. The canopy assembly as claimed in claim 1, wherein said annular decorative ring is made of rigid material.

7. The canopy assembly as claimed in claim 6, wherein said annular decorative ring is made of aluminum alloy.
