Abstract
An Assembling structure for vane and vane bracket of ceiling fan, including a vane bracket and a vane. The vane bracket has several bosses and at least one projecting post. A resilient press board is pivotally disposed on top face of the projecting post. An end of the press board distal from the projecting post has a downward extending press section. The vane is formed with dents complementary to the bosses of the vane bracket. The vane is further formed with a slot corresponding to the projecting post of the vane bracket. The press board is passed through the slot. The vane is formed with a locating section in which the press section of the press board is located. When connecting the vane bracket with the vane, the press board is rotated to make the press section of the press board resiliently pressed against and located in the locating section of the vane by means of the resilient force of the press board so as to quickly and conveniently fixedly connect the vane bracket with the vane.
Description
BACKGROUND OF THE INVENTION
The present invention is related to an assembling structure for vane and vane bracket of ceiling fan, which enables a user to quickly and conveniently assemble the vane bracket and the vane with each other.
FIG. 6
shows the vane
81
and vane bracket
82
of a conventional ceiling fan. The vane bracket
82
is formed with three thread holes
821
. The vane
81
is formed with three through holes
811
corresponding to the thread holes
821
. Bolts
83
are passed through the through holes
811
of the vane
81
and screwed into the thread holes
821
of the vane bracket
82
so as to fix the vane
81
on the vane bracket
82
.
The vanes
81
and the vane brackets
82
are separately packed and assembled when installing the ceiling fan. A general ceiling fan has four to seven sets of vanes
81
and vane brackets
82
. When assembled, it is necessary to tighten three bolts
83
for assembling each set of vane
81
and vane bracket
82
. Accordingly, it is necessary to tighten at least
12
˜
21
bolts
83
for assembling all the vanes
81
and the vane brackets
82
. This is a troublesome procedure for a DIY user.
FIGS. 7 and 8
show the vane
91
and vane bracket
92
of another type of conventional ceiling fan. The vane bracket
92
has multiple posts
93
. Each post
93
has two upward projecting stop blocks
931
. When a stop plate
932
is locked on the post, the stop blocks
931
serve to restrict the stop plate
932
. The vane bracket
92
further has a pivot block
94
between the posts
93
for pivotally connecting with an eccentric press lever
95
. The vane
91
is formed with slots
911
,
912
for the stop plate
932
and eccentric press lever
95
to pass therethrough.
When connecting the vane
91
with the vane bracket
92
, the slots
911
,
912
of the vane
91
are aimed at the stop plate
932
and eccentric press lever
95
and then fitted onto the vane bracket
92
. The stop plate
932
and eccentric press lever
95
extend out of the slots
911
,
912
. Then the vane
91
is pulled outward to engage the stop plate
932
with top face of the vane
91
. Then a washer
96
is fitted under the eccentric press lever
95
and the eccentric press lever
95
is depressed to press the washer
96
. At this time, the vane
91
is pressed against and connected with the vane bracket
92
.
The above vane
91
and vane bracket
92
have complicated structure and are manufactured at high cost. Moreover, it is troublesome to assemble the vane and vane bracket for a DIY user. In the case that the stop plate
932
and eccentric press lever
95
are previously assembled in the factory, the cost for assembling procedure is increased. Furthermore, the vane
91
is formed with several slots
911
,
912
which weaken the strength of the vane
91
. Therefore, the vane
91
is liable to break.
SUMMARY OF THE INVENTION
It is therefore a primary object of the present invention to provide an assembling structure for vane and vane bracket of ceiling fan, including a vane bracket and a vane. The vane bracket has several bosses and at least one projecting post. A resilient press board is pivotally disposed on top face of the projecting post. The vane is formed with dents complementary to the bosses of the vane bracket for inserting the bosses into the dents. The vane is further formed with a slot corresponding to the projecting post of the vane bracket. The press board is passed through the slot. The vane is formed with a locating section in which the press section of the press board is located. When connecting the vane bracket with the vane, the press board is rotated to make a press section of the press board resiliently pressed against and located in the locating section of the vane by means of the resilient force of the press board so as to quickly and conveniently fixedly connect the vane bracket with the vane.
The present invention can be best understood through the following description and accompanying drawings wherein:

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Please refer to
FIGS. 1
to
4
. The assembling structure for vane and vane bracket of ceiling fan, including:
a vane bracket
1
having a connecting section
11
which in this embodiment is substantially Y-shaped, each of two ends of the connecting section
11
having a boss
12
, a middle portion of the connecting section
11
having a projecting post
13
, a resilient press board
2
being pivotally disposed on top face of the projecting post
13
, the end of the press board
2
distal from the projecting post
13
having a downward extending vertical section
21
, a rubber press block
22
being fitted with the bottom end of the vertical section
21
, the rubber press block
22
being a semispherical body; and
a vane
3
formed with dents
31
complementary to the bosses
12
of the vane bracket
1
for inlaying the bosses
12
in the dents
31
, the vane
3
being formed with a slot
32
corresponding to the projecting post
13
of the vane bracket
1
, the press board
2
being passed through the slot
32
, the vane
3
being formed with a locating section
33
which is a recess in this embodiment, after the press board
2
is rotated, the press block
22
being located in the locating section
33
, the locating section
33
being positioned at an outer end of an extension line defined by the center of the projecting post
13
and the center of the ceiling fan, that is, the locating section
33
being positioned at an outermost position of the rubber press block
22
when the press board
2
suffers a centrifugal force and rotates, when the vane bracket
1
is connected with the vane
3
, the press board
2
is rotated to resiliently press the rubber press block
22
against the recess
33
of the vane
3
so as to fix the vane bracket
1
with the vane
3
.
When assembled, the press board
2
on the projecting post
13
is first rotated to align the press board
2
with the slot
32
of the vane
3
. Then the vane
3
is fitted onto the vane bracket
1
with the bosses
12
of the vane bracket
1
inserted into the dents
31
of the vane
3
and with the projecting post
13
passing through the slot
32
. At this time, the press board
2
is extended out of the slot
32
and rotated to press the rubber press block
22
of the vertical section
21
of the press board
2
against the recess
33
of the vane
3
. Therefore, the rubber press block
22
is resiliently located in the recess
33
by means of the resilient force of the press board
2
so as to quickly and conveniently fixedly connect the vane bracket
1
with the vane
3
without using any bolt. In addition, the recess
33
is positioned at an outermost position of the rubber press block
22
when the press board
2
suffers a centrifugal force and rotates during rotation of the vane
3
and the vane bracket
1
. Therefore, the press board
2
will not be deflected in use so that the vane
1
and the vane bracket
3
are firmly connected with each other. The rubber press block
22
is a semispherical soft body so that it will not scrape the surface of the vane
3
when the vane
3
moves. Moreover, the rubber material helps in tightly pressing the press board
2
against the vane
3
.
FIG. 5
shows a second embodiment of the present invention, in which the end of the press board
4
distal from the projecting post
13
has a downward projecting press section
42
which is made by punching. The press section
42
is similarly resiliently located in the recess
53
of the vane
5
by means of the resilient force of the press board
4
so as to quickly and conveniently fixedly connect the vane bracket
1
with the vane
5
.
The above embodiments are only used to illustrate the present invention, not intended to limit the scope thereof. Many modifications of the above embodiments can be made without departing from the spirit of the present invention.
