Description

[Detailed Description of the Invention] The present invention relates to a fan stand that supports the main body of the fan rather than a fan motor or the like.

1 to 4 show conventional electric fans.

The electric fan 1 includes a fan main body 3 consisting of a fan motor 2, etc.
It consists of a fan stand 4 that stably supports the fan main body 3.

The electric fan stand 4 includes a disc-shaped base 5 and a cylindrical support 6 projecting from the center of the base 5.

A sliding support rod 7 that is slidable in the vertical direction is attached to the support column 6, and the fan main body 3 is attached to the tip of the support rod 7 so as to be rotatable in the horizontal direction and the vertical direction.

Although not shown in the drawings, the base 5 is equipped with electrical components such as switches, and after the electrical components are installed, the bottom opening of the base 5 is closed by the bottom plate 8.

The bottom plate 8 is attached by screwing fixing screws 11 inserted through screw insertion holes 10 of the bottom plate into a plurality of bosses 9 vertically provided in the base 5.

Further, the bottom plate 8 is attached to the stand 5 by the fixing screws 11, and at the same time, a plurality of elastic support legs 1 are attached to the stand 5.
2... is installed.

The stand 1 located between each of the support legs 12...
At the lower edge of the support leg 12...the shorter auxiliary leg 13...
The auxiliary legs 13 contact the floor 14 only when the stand 4 is tilted, and prevent the stand 4 from tilting too much.

Therefore, the distance between the lower ends of the auxiliary legs 13 and the floor surface 14 is set to an appropriate value.

However, in order to obtain variations in electric fans as products, fan stands were commonly used and the main body of the electric fan was changed to one with a larger diameter.

Therefore, in order to support the main body of the electric fan more stably, it is necessary to increase the weight of the lower part of the stand.

Therefore, the bottom plate 8 is used as a weight and a plurality of bottom plates are fixed to the stand 4, but the thickness of the bottom plate is substantially increased, and the fixing screw 11 that used to fix one bottom plate 8 is not used. Since the amount of screwing into the boss portion 9 is reduced, it is necessary to use a long screw 11.

Further, since the supporting legs 12 protrude from the stand 4 by the increased thickness of the bottom plate 8, the supporting legs 13 and the floor surface 14
The distance between the two legs increases, and the function as an auxiliary leg decreases.

In view of the above points, the present invention provides a fan stand that allows the necessary number of bottom plates to be attached to the stand without changing the distance between the fan stand and the floor.
An embodiment of the present invention will be described below with reference to FIGS. 5 and 6 based on the case where one or two bottom plates are attached to the stand.

Note that the description of parts having the same structure as the conventional one will be omitted and will be designated by the same reference numerals.

A plurality of vertically extending bottom plate abutment ribs 15, 15, . The lower ends of the ribs 15, 15, .

The bottom plate 16 is formed with screw insertion holes 17, 17, . 18, 18... are formed.

Therefore, when one bottom plate 16 is attached to the stand 4, it is sufficient to align the through holes 17 of the bottom plate with the boss portions 9 and screw the screws 11 into the boss portions 9.

In addition, when two bottom plates 16, 16' are attached to the stand 4, the through holes 18 in the bottom plates are aligned with the boss portions 9, and the through holes 18 are inserted into the boss portions 9. After fitting the bottom plate 16' to the stand 4, align the through holes 17 of the other bottom plate 16 with the bosses 9, and insert the screws 11 into the bosses 9. Just screw it in.

Furthermore, at the same time as the bottom plates 16, 16' are attached, the elastic support legs 12 are attached to the stand as in the conventional case.

In this way, the bottom plate 16, 1 is attached to the stand 4.
Even when one or two 6' are attached, the distance between the stand 4 and the floor 14 does not change, so the function of the auxiliary legs 13 is not impaired, and the center of gravity is It is secured at a sufficiently low position.

In this embodiment, the two bottom plates 16 and 16' are attached as necessary, but when two or more bottom plates are attached, the lower end of the rib formed on the boss portion 9 may be attached. are formed in a step-like manner, and the diameters of the envelope circles connecting the lower end side edges of the ribs are made different, and several types of through holes with the same diameter as the diameter of the envelope circles are formed in the bottom plate, and the necessary number of ribs are formed. It is preferable to attach the bottom plate to the stand by changing the through hole that fits into the boss portion 9 depending on the situation.

Further, a plurality of protrusions that can be crushed by pressure are formed on the side surface of the boss portion 9, and a necessary number of bottom plates identical to those of the above-mentioned embodiment are pushed into the boss portion 9. Then, the protrusion may be crushed and a bottom plate may be added and attached.

As described above, in the present invention, the bottom plate that closes the lower opening of the electric fan stand has a through hole through which a fixing screw is inserted, which is screwed into the bottom plate fixing boss part vertically installed in the stand, and the bottom plate is rotated or reversed by a certain angle. At the same time, since the fan stand is formed with a through hole that fits into the boss part, the necessary number of bottom plates can be installed on the stand using one type of bottom plate, without changing the distance between the fan stand and the floor. This has great practical effects, such as being able to be attached using the fixing screws and obtaining a stable fan stand with a simple structure.
