BACKGROUND OF THE INVENTION

1. Field of Invention

The invention relates to an improved hanging frame of the ceiling fan and, in particular, to the hanging frame that supports a ceiling fan conversion base.

2. Related Art

FIGS. 5 and 6 show a hanging frame of the ceiling fan in the prior art. It has a supporting base 9 whose one side has an opening 91. Both sides of the opening 91 on the supporting base 9 extend upwards with an ear part 92, respectively. The end of each of the ear parts 92 is provided with a fixing part 93 outwards. The center of the supporting base 9 has a through hole 94. The rim of the through hole 94 on the supporting base 9 extends upwards with several supporting parts 95.

Please refer to FIG. 7 for a second hanging frame of the ceiling fan. It has a supporting base 9A whose one side has an opening (not shown). Both sides of the opening on the supporting base 9A extend upwards with an ear part 92A, respectively. The end of each of the ear parts 92A is provided with a fixing part 93A outwards. The center of the supporting base 9A has a through hole 94A. The rim of the through hole 94A on the supporting base 9A extends downwards with several supporting parts 95A.

As seen in the above-mentioned conventional structures, when the conversion base 96 of a ceiling fan is hung on the supporting parts 95 in the through hole 94 of the supporting base 9 in the first hanging frame or the supporting parts 95A in the through hole 94A of the supporting base 9A in the second hanging frame, the only contact parts are the supporting part 95 or 95A. Therefore, whether the supporting parts 95 extend upwards along the rim of the through hole 94, as shown in FIGS. 5 and 6, or downwards along the rim of the through hole 94A, as shown in FIG. 7, the supporting area is small. In this case, the supporting base 9 or 9A has merely the function of supporting the conversion base 96. However, when the ceiling fan is in operation, there is a certain torque that causes the ceiling fan to wiggle. Thus, when using the conventional supporting base 9 or 9A to support the conversion base 96, the ceiling fan wiggles as it runs. Moreover, the wiggling gets stronger when the ceiling fan is running at high speeds.

Therefore, it is the goal of the invention to solve the wiggling problem of the above-mentioned conventional hanging frame structure.

SUMMARY OF THE INVENTION

An objective of the invention is to provide an improved hanging frame of the ceiling fan. Using the holding parts and the supporting parts of the supporting base in the invention, the conversion base of the ceiling fan can be concurrently held and supported. The ceiling fan is thus more stable during its operation.

Another objective of the invention is to strengthen the supporting base to prevent its deformation, thereby reducing the wiggling of the ceiling fan. According to the invention, the supporting base uses the second buckling parts of a connecting element to connect with the first buckling parts near the end of the opening.

The disclosed hanging frame according to the invention includes a supporting base. The two opposite sides on the outer edge of the supporting base extend upwards with an ear part, respectively. The top end of each of the ear parts extends horizontally outwards with a fixing part. The supporting base has a through hole inside. It further has an opening on the side adjacent to the two ear parts and in communication with the through hole. A positioning protrusion is formed along the rim of the through hole towards its center for positioning the conversion base of the ceiling fan. The rim of the through hole on the supporting base is extended upwards with several holding parts and downwards with several supporting parts. Each of the holding parts holds the conversion base. Each of the holding parts is curved upwards to form a first supporting section and has a curvature corresponding to that of the round section at the outer edge of the conversion base for supporting it. Each of the holding parts extends from the top edge of the first supporting section a first holding section. The first holding sections hold a straight section extended upwards from the outer edge of the conversion base. The straight section has a diameter equal to the maximum diameter of the round section. Each of the supporting sections supports the conversion base from the bottom of the through hole.

DETAILED DESCRIPTION OF THE INVENTION

The present invention will be apparent from the following detailed description, which proceeds with reference to the accompanying drawings, wherein the same references relate to the same elements.

Please refer to FIGS. 1 to 3 for a first embodiment of the invention. In this embodiment, the improved hanging frame of a ceiling fan has a supporting base 1. The two opposite sides of the outer edge 11 of the supporting base 1 extend upwards with an ear part 12, respectively. The top of each of the ear parts 12 extends horizontally outwards with a fixing part 13. In this embodiment, each of the fixing parts 13 has several positioning holes 131 for positioning.

The supporting 1 has a through hole 14 inside. One side of the supporting base 1 between the two ear parts 12 has an opening 15 in communication with the through hole 14. The conversion base 2 of a ceiling fan (not shown) can enter via the opening 15 and hanging in the through hole 14 of the supporting base 1. A positioning protrusion 16 is formed on the edge of the through hole 14 on the supporting base 1 towards its center. It positions the conversion base 2 of the ceiling fan. Therefore, the conversion base 2 does not rotate when the ceiling fan is running.

The rim of the through hole 14 extends upwards with several holding parts 17 and downwards with several supporting parts 18. Each of the holding parts 17 holds the conversion base 2. Each of the supporting parts 18 supports the conversion base 2 from the bottom of the through hole 14. In this embodiment, each of the holding parts 17 extends in a curve upwards with a first supporting section 171. Each of the first supporting sections 171 has a curvature corresponding to that of a round section 21 at the outer edge of the conversion base 2. Each of the holding parts 17 extends from the top of the first supporting section 171 upwards with a first holding section 172. The first holding section 172 holds a straight section 22 extended upwards from the top of the round section 21 at the outer edge of the conversion base 2. The straight section 22 has a diameter equal to the maximum diameter of the round section 21. (One can define an imaginary line 4 to divide the round section 21 on the outer edge of the conversion base 2 and the straight section 22.)

When the conversion base 2 of a ceiling fan is disposed inside the supporting base 1, each of the holding parts 17 uses its first supporting section 171 to support the round section 21 of the conversion base 2. The first holding section 172 of each of the holding parts 17 can slightly hold the straight section 22 of the conversion base 2. Each of the supporting parts 18 also supports the conversion base 2 at the same time. As shown in FIG. 3, the first supporting sections 171 and the first holding sections 172 of each of the holding part 17 on the supporting base 1 urge the conversion base 2 by an area larger than the conventional supporting base. Moreover, they concurrently hold and support the conversion base 2. When the ceiling fan is operating, the conversion base 2 is more stable than the conventional hanging frame.

Of course, the invention has many other embodiments that differ only in details. Please refer to FIG. 4 for a second embodiment of the invention. Both sides of the opening 15 on the supporting base 1 have a first buckling part 19, respectively, for a connecting element 3 to connect. In this embodiment, the first buckling part 19 is a protrusion upwards from the end of the supporting base 1 near the opening 15. Both ends of the connecting element 3 respectively have a second buckling part 31 that connects with the corresponding first buckling part 19. Each of the second buckling parts 31 is a connecting hole 19 for the corresponding first buckling part 19 of the supporting base 1. Each of the first buckling parts 19 goes through the second buckling part 31 and extends upwards. The protruding part is bent to stop the corresponding second buckling part 31, thereby positioning the connecting element 3.

The supporting base 1 has an opening 15 for the conversion base 2 to be disposed in the through hole 14 when the ceiling fan is connected. The conversion base supported by the supporting base 1 wiggles when the fan is running. Thus, the opening 15 of supporting base 1 will expand and deform after the fan is used for some time. The wiggling between the conversion base 2 and the supporting base 1 becomes more apparent. The second buckling parts 31 of the connecting element 3 in this embodiment connect with the corresponding first buckling parts 19 near the ends of the opening 15. This enhances the strength of the supporting base 1 for supporting the conversion base 2. It prevents the deformation of the supporting base 1 and strong wiggling of the conversion base 2 as the fan runs.

Although the invention has been described with reference to specific embodiments, this description is not meant to be construed in a limiting sense. Various modifications of the disclosed embodiments, as well as alternative embodiments, will be apparent to people skilled in the art. Therefore, it is contemplated that the appended claims will cover all modifications that fall within the true scope of the invention.
