Description

[Detailed explanation of the idea] This proposal relates to a ceiling fan that is used by being attached to a ceiling surface.

Conventionally, as disclosed in Japanese Patent Laid-Open No. 51-88368, ceiling fans are attached to a mounting base fixed to the ceiling surface by engaging hook pieces formed on the bottom plate of the ceiling fan body. It could easily come off due to vibration.

In view of the above points, the purpose of this proposal is to ensure the installation of a ceiling fan on the ceiling surface, and to prevent damage to the lead wires when installing the ceiling fan.
The base of the ceiling fan is placed on a mounting plate attached to the ceiling surface, rotated by a predetermined angle, and the locking metal fittings in the base are locked to the hooks formed at two places around the periphery of the mounting plate. In addition, in the case where a screw inserted from the side surface of the base is screwed into a bent piece formed on the periphery of this mounting plate to fix it, there is a part in the base opposite to the insertion part of the screw. A condenser storage chamber is formed on the side, and when the new bent piece is positioned on the side of the capacitor storage chamber when the base is attached to the mounting plate, the bent piece comes into contact with the locking metal fitting and the hook piece. A projection is formed on the lid of the storage chamber to prevent engagement with the storage chamber.

To explain the main idea below based on the diagram, 1 is a plastic base with an open top and a hollow interior.It has an elliptical shape that is slightly elongated in the left and right direction, and a pair of support legs are attached from both left and right ends of the base. 2, 2 are vertically installed, and a ring 3 for swinging head is swingably supported between the lower ends by bolts 4.4, and a pair (not shown) is provided in a direction perpendicular to the bolts 4, 4. A motor 5 is pivotally supported on the ring 3 by a bolt, so that the motor can pivot.

A fan 6 is attached to the tip of the motor shaft, and is surrounded by a guard 7 to constitute an electric fan.

Further, a reduction gear mechanism 8 connected to the motor shaft via a reduction gear mechanism protrudes from the rear end side of the motor. They are connected by a swing rod 10.

Note that the pin 9 is connected to a cylindrical projection 11 provided at the center of the base.
It is rotatably inserted through the.

Further, a circular rib 12 is formed in the base 1 to reinforce the base, and radial ribs 13, 13... are formed between the circular rib and the outer wall of the base. In addition, a rib 15 for forming the container storage chamber 14 is formed.

16 is a locking metal fitting that is bent into a substantially gate shape and serves as reinforcement.
insert the base from the top opening and tighten both lower ends with the bolts 4.
, 4, the through hole 17 drilled in the center of the reinforcing metal fitting is fitted into the center protrusion 11 of the base for positioning, and the horizontal part of this reinforcing metal fitting is fixed to the base by screws 18 and 18. It is fixed to a boss portion 19.19 protruding from the base.

Reference numeral 20 denotes a lid that covers the upper opening of the container storage chamber 14, and protrusions 21 and 21 integrally formed at both ends of the negative side edge are inserted into the lower surface of the locking metal fitting 16, and are inserted diagonally downward from the center. The container 23 is held down by an elastic piece 22 integrally formed to protrude toward the lid 20, and a screw 25 is inserted through a through hole 24 formed in the lid 20, and then inserted into a boss 26 protruding into the capacitor storage chamber 14. This lid 20 is fixed by screwing together.

On the upper surface of this lid 20, on the side edge opposite to the protrusions 21, 21, there is a protrusion 27 slightly closer to one side than the center thereof.
has been established.

The function of this protrusion will be described later.

28 is a circular mounting plate attached to the ceiling, and has a slightly smaller outer diameter than the circular rib 12 of the base;
Hook pieces 29 and 29 are bent at two opposing locations on the periphery, and a bent piece 30 is provided in the middle of the two hook pieces, and a screw hole 31 is bored in the center of the new bent piece.

In order to attach the base 1 to the mounting plate 28 in such a configuration, first place the base 1 on the mounting plate, and then turn the base so that the horizontal part of the locking metal fitting 16 is attached to the mounting plate. Hook piece 29
, 29.

At this time, the tabs 1 to 32 protruding from the inner surface of the base hit the bending piece 30 of the mounting plate and remain in a predetermined position.

If this continues, there is a risk that the base 1 will rotate due to vibrations during operation and the engagement may come off, so insert the screw 34 through the notch 33 provided on the side surface of the base 1 and insert the screw 34 into the screw hole of the bent piece 30. 31 to completely fix this base 1.

Since the base 1 and the mounting plate 28 are symmetrical, they can be mounted even if the base 1 is turned in the opposite direction by 180 degrees.

However, when the base 1 is applied to the mounting plate 28 in this state and the base 1 is rotated, the capacitor storage chamber 14 side of the base will come to the new music piece 30 side of the mounting plate, so that the capacitor storage chamber 14 side of the base will come to the new music piece 30 side of the mounting plate. There is a risk that the lead wire 35 that has been pulled out may be caught by the bent piece 30 and be broken when the base 1 is strongly rotated.

However, in this case, since the protrusion 27 is provided on the lid 20 covering the capacitor storage chamber, the base 1 is
° If the projection 27 is rotated in the opposite direction, the protrusion 27 hits the bending piece 30 on the mounting plate side, preventing further rotation.
The locking fitting 16 does not engage with the hook on the mounting plate side.

FIG. 5 shows this state.

Therefore, it can be determined that the mounting direction is incorrect, and the mounting direction can be corrected.

Furthermore, the protrusion 27 on the lid can also be used as a legitimate child when the lid is removed.

As described above, in the present invention, the base 1 is applied to the mounting plate 28 which is mounted on the ceiling in advance, and this is rotated by a predetermined angle to engage the locking metal fitting 16 in the base with the mounting plate. In the case where the screw 34 inserted from the side of the base is screwed into the bent piece 30 of the mounting plate and fixed, a protrusion 27 is attached to the lid 20 of the capacitor storage chamber 14 provided in the base 1. Set up, base 1
If you try to install it in the opposite direction, this protrusion 27
Since the bending piece 30 hits the base 1 and prevents it from rotating, the base 1 is forced to rotate and the lead wires 14 coming out of the container storage chamber 14 are connected to the lead wires 14. This prevents the lead wire from being hooked, tearing it off, and causing electrical leakage.
