Abstract

PURPOSE:To reduce the number of parts and carry out installation with a saved space by fitting a suspending member having elasticity in a hole which is opened through a suspending pipe and engingingly hooking the groove of the suspending member by the lower portion of a mounting fixture. CONSTITUTION:A suspending pipe 9 is erected on the upper part of the center of an electric motor 1 on which blades 2 are installed. A square hole 10 is provided laterally through the upper end portion of the suspending pipe 9 and a suspending member 11 having elasticity is inserted therein. A semicircular groove 14 provided on the suspending member 11 is fittingly hooked by the hooking portion 7a of a mounting fixture 7 which is screwed and fixed to a ceiling 8, to easily and surely install the suspending pipe 9 on the mounting fixture 7. Thereby, the number of parts can be reduced while enabling installation with a saved space even in a place of a low ceiling.

Description

[Detailed description of the invention] Industrial applications The present invention relates to a hanging device for a ceiling fan.

BACKGROUND OF THE INVENTION In recent years, ceiling fans have been used for their energy-saving and interior design features.

As shown in FIGS. 5 and 6, a conventional hanging device for a ceiling fan of this type has a hanging pipe 3 fixed to an electric motor 1 to which blades 2 are attached, and a horizontal wall attached to the upper end of the hanging pipe. A round hole 4 penetrating in the direction is provided. On the other hand, a U-shaped mounting bracket 7 is fixed to the ceiling 8 which is the mounting part. and,
One end of the U-shaped hanging bracket 6 is inserted into the round hole 4, a pulley 6 is installed at the other end, and the U-shaped mounting bracket 7 is fitted into the groove formed on the outer periphery of the pulley 6. By being hooked, the electric motor 1 was suspended from the ceiling 8 via the hanging pipe 3.

In the above configuration, when the electric motor 1 rotates and generates vibrations or shakes due to the influence of wind, the U-shaped mounting bracket 7 is fitted onto the outer periphery of the pulley 6, so that the pulley A buffering effect works between the motor 6 and the mounting bracket 7, preventing vibration and shaking, and the electric motor 1 is stably suspended from the ceiling 8 via the suspension pipe 3.

Problems to be Solved by the Invention However, in the above conventional configuration, in order to suspend the electric motor 1 from the U-shaped mounting bracket 7 attached to the ceiling 8, many accessories such as the pulley 5 and the U-shaped hanging bracket 6 are required. It requires parts and has problems in terms of installation man-hours and cost.

Furthermore, since the hanging pipe is attached under the mounting bracket via the pulley 6 and the hanging bracket 6, there are problems in that the installation space is large and it is difficult to install on a low ceiling.

The present invention solves the above-mentioned conventional problems, and aims to provide a hanging device for a ceiling fan that can reduce the number of parts and can be installed in a space-saving manner.

Means for Solving the Problems In order to solve the above problems, the hanging device for a ceiling fan of the present invention has a hole formed in the upper part of the hanging vibrator that passes through the hanging vibrator in the horizontal direction, and a hole is formed in the upper part of the hanging vibe. An elastic hanging tool is inserted, and the hanging tool has a protrusion provided on its upper surface that is press-fitted into the inner circumferential surface of the hanging vibrator and is fixed thereto, and a semicircular part is attached to the lower part of the hanging tool. An arc-shaped groove is provided, and an arc-shaped hook portion of a single-shaped mounting bracket attached to the ceiling is engaged with this groove.

Function: In this configuration, the ceiling fan is suspended by engaging the hook part of the single-shaped mounting bracket screwed and fixed to the ceiling with the semicircular arc groove of the hanging fixture, and the hanging vibrator and the ceiling mounting bracket are suspended. There is no need for a pulley or U-shaped hanging tool between the two, and the number of component parts can be simplified.

EXAMPLE An example of the present invention will be described below with reference to FIGS. 1 to 4. It should be noted that the same components as those in the prior art are given the same numbers and detailed explanation thereof will be omitted.

As shown in the figure, a hanging vibrator 9 is erected above the center of the electric motor 1 to which the blades 2 are attached. A square hole 10 is passed through the upper end of the hanging vibrator 9 in the horizontal direction, and an elastic hanging tool 11 is inserted therein. This hanging tool 1
1 has an upper surface convex portion 11a, and the hanging tool 11 is fixed by press-fitting this convex portion 11a into the inner circumferential surface 9a of the hanging vibrator 9.

Furthermore, the hanging tool 11 has a semicircular arc-shaped groove 14 at its lower part, and this groove 14 has a size such that the outer shape of the hook part 7a of the mounting bracket 7 engages with it.

In the above configuration, a semi-circular groove 14 is provided in the hanging fixture 11 in the hook part 7a of the mounting bracket 7 screwed and fixed to the ceiling 8.
By hooking it so that it fits, the hanging vibrator 9 can be easily and reliably attached to the mounting bracket 7.

Also, since the groove 14 of the elastic hanging tool 11 and the hook part 7a of the mounting bracket 7 are evenly engaged, it exhibits the same vibration-proofing effect as a conventional pulley against vibrations caused by the rotation of the electric motor 1. It is something to do.

Effects of the Invention As is clear from the description of the embodiments above, according to the present invention, an elastic hanging tool is attached to the hole penetrating the hanging vibrator, and the hanging tool is engaged with the groove at the bottom of the mounting bracket. By hooking them together, they can be hung, and the number of parts for hanging can be reduced. Furthermore, it is possible to realize an excellent hanging device for a ceiling fan that can be installed in a space-saving manner even in a place with a low ceiling.
