Abstract
A suspending structure of a ceiling fan is disclosed. Since in the prior art suspending structure of a ceiling fan, the swinging angle of a swinging pipe set is confined by the assembly hole of a suspender, a swinging pipe set, a hanging bell and other components. Therefore, the swing is preformed in a small angle. For a surface (such as ceiling) with a large inclined angle, it can not be used and is very dangerous. Therefore, in the present invention, two sides of the assembly hole of a suspender are formed with a cavity and an opening, and the engaging hole of the hanging bell is formed with long sides. Two ends of the long side are placed on the cavity and opening of the suspender. Thereby, as the swinging pipe set shifts toward said cavity, said swinging pipe is received within one end of said long side of the cavity. Therefore, a swing of large angle is generated, moreover, said swinging path of the swinging pipe set is confined by said buckle and said trench. Thus, the suspending structure according to the present invention can be suitable for a non-horizontal surface with a large angle shift safely.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS




With reference to

FIGS. 2 and 3

, the suspending structure of a ceiling fan according to the present invention is illustrated. The suspending structure of the present invention mainly includes a suspender


20


, a swinging pipe set


30


and a hanging bell


40


.




The suspender


20


is installed with a frame


21


and two sets of fixing ears


22


. The frame


21


is installed with an assembly hole


23


. The fixing ears serve to combine with an assembling surface


50


(for example, a ceiling). A cavity


24


and opening


25


are installed at opposite sides of the frame


21


in the suspender


20


. The frame


21


at one side of the cavity


24


is protruded with a buckle


26


.




One end of the swinging pipe set


30


is formed as a hanging head as a hemisphere, while another end is formed as a swinging pipe


32


. A trench


311


is formed on the hanging head


31


. The swinging pipe set


30


can be installed to the assembly hole


23


of the suspender


20


through the hanging head


31


. The buckle


26


is embedded into the trench


311


and is swingable therein.




The hanging bell


40


is disposed as a cover, and an engaging hole


41


is formed thereon. The engaging hole


41


is an opening with long sides and short sides. The swinging pipe


32


can pass through the engaging hole


41


to combine the hanging bell


40


with the suspender


20


as a shielding cover of the suspending structure. The first end


411


and second end


412


at the long side of the engaging hole


41


are located at positions with respect to the cavity


24


and opening, respectively.




Thereby, after the aforesaid suspender


20


, swinging pipe set


30


, hanging bell


40


are assembled, the buckle


26


is embedded into the trench


311


, and the first end


411


and second end


412


at the long sides of the engaging hole


41


are placed at the cavity


24


and opening


25


of the suspender


20


. Thereby, as the swinging pipe set


30


swings toward the first end


411


of the engaging hole


41


, the swinging pipe


32


can be received within the cavity


24


(not to be hindered by the frame). Therefore, the swinging pipe set


30


may swing along a large traveling length. Moreover, the swing track is confined by the buckle


26


and the trench


311


. That is, the swing path is along the trench


311


. It is appreciated that the maximum swing length is wider than that in the prior art, and the structure is steady and safe.




If should be noted, referring to

FIG. 5

, as the swinging pipe set


30


swings toward the second end


412


of the engaging hole


41


, the orientation of the suspender


20


is changed so that the cavity is at position with respect to the second end


412


, and opening


25


is at position with respect to first end


411


(in

FIG. 5

, the cavity is with respect to the first end, and the opening is with respect to the second end).




Moreover, in the present invention, an angled frame


60


serves to install the ceiling fan with a shift to the horizontal direction, or serves to install the ceiling fan at wall or between beams, as shown in FIG.


5


. In general, as a ceiling fan is installed, it is general that the ceiling fan is not installed at the connections of the beams or walls, or angled wall. However, these will cause the places for installing the ceiling fan is confined greatly. Since the suspending structure of a ceiling fan in the present invention can be used in a non-horizontal surface (


50


), and therefore, as shown in the figures, the angled frame


60


is firmly secured to places such as connections of beams and walls, and then the suspending structure of the present invention is firmly secured thereto (the suspender


20


is combined with the angled frame


60


). That is, the concave space can be installed to a surface (


50


) with a large angle therebetween.




In summary, in the present invention, as it is embodied, two sides of the assembly hole of the suspender are installed with cavity and opening, and the engaging hole of the hanging bell is formed with long sides. Two ends of each long side are placed at the cavity and opening of the suspender, Therefore, as the swinging pipe set swings toward the cavity, the swinging pipe can be received within the end of the long side of the cavity so that a large swing is tolerable. Moreover, by the engagement of the buckle and the trench, the suspending structure of a ceiling fan according to the present invention can be safely installed to a non-horizontal surface with a large angle shift.




Although the present invention has been described with reference to the preferred embodiments, it will be understood that the invention is not limited to the details described thereof. Various substitutions and modifications have been suggested in the foregoing description, and others will occur to those of ordinary skill in the art. Therefore, all such substitutions and modifications are intended to be embraced within the scope of the invention as defined in the appended claims.
