Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a fan having a configuration in which the height of the fan head can be adjusted.

[Technical Background of the Invention] Conventionally, as shown in FIG. By attaching the neck support 4 to the upper end and supporting the fan head 5 by the neck support 4,
A fan is provided in which the height of the fan head 5 can be arbitrarily adjusted. In this case, a guide vibro is arranged inside the support section 2 as shown in FIG.
An elevating column 3 is inserted into the guide vibro, and a spring 7 that gives a lifting force to the elevating column 3 is disposed within the elevating column 3 with a spring receiver 8 as a guide. A brake root 10 having a knob 9 on the upper part thereof is brought into pressure contact with the lifting column 3 by the displacement force of the spring 11, so that the lifting column 3 is pressed against the spring 7.
A brake device 12 is provided to hold the fan head 5 at an arbitrary height position by resisting the rising force caused by the fan head 5.

[Problems with the front lighting technology] However, in the above-mentioned conventional device, when the fan head 5 is raised even slightly from the lower limit position where the neck support 4 contacts the column 2, the elevating column 3 does not come into contact with the column 2 and the neck. Particularly, the elevating column 3 has a considerably smaller diameter than the column 2, and the outer diameter of the lifting column 3 is considerably smaller due to the fact that the plate 10 is pressed into contact with the plate 10. The brake plate 10 is limited to a cylindrical shape and does not necessarily match the shape of the support column 2 or the neck support 4, and the surface is covered with a hard metal such as stainless steel I in order to reduce the occurrence of scratches due to the pressure welding of the brake plate 10. A column 2 and a neck support 4, which are necessary and usually made of plastic.
Unlike others, it emits a metallic luster, which poses the problem of giving the user a sense of discomfort when it is visible. Even if the surface of the lifting column 3 is covered with a hard metal such as stainless steel as described above, some marks, if not scratches, will remain on the surface due to the pressure welding of the brake plate 10. There is also the problem that it is visible and spoils the appearance.

[Object of the Invention] The present invention has been made in view of the above-mentioned circumstances, and therefore, its object is to prevent the user from feeling uncomfortable due to the elevating column.
Further, it is an object of the present invention to provide a rotted electric fan that has a good appearance without showing any brake marks on its elevating column.

[Summary of the Invention] The present invention is characterized in that the support column of the base and the neck support are provided so that they always overlap and cover the lifting column.

[Embodiment of the Invention] An embodiment of the present invention will be described below with reference to FIGS. 1 to 3. First, in FIGS. 2 and 3, reference numeral 21 denotes a base, and a support portion 22 is erected at a portion of the upper surface near the rear. Specifically, as shown in FIG. 1, the support column 22 has a hollow shape, and has a thin section 22b extending from the top thereof, which is narrower by one step than the step section 22a. Reference numeral 23 denotes an elevating column, which is inserted into the above-mentioned column portion 22 so as to be able to slide up and down, and a neck support 24 is attached to the upper end of the elevating column 23 that protrudes from the column portion 22. 24 supports the mmm head 25 shown in FIGS. 2 and 3.

Here, the neck support 24 is also formed with a hollow lower part as shown in FIG.
The inner diameter is set to be approximately the same as the outer diameter of the cotton-like portion 22b, and the wall thickness is set to be approximately the same as the stepped portion 22a.
The length of the fan head 25 is larger than the narrow part 22b.
The dimensions are set such that it continues to overlap with the narrow portion 22b even when it is raised to the upper limit position. In addition, the support section 22 is provided with a guide vibe 26 for guiding the vertical movement of the elevating column 23 as in the conventional case. Spring 27 that applies upper back force to the lifting column 23. Spring receiver 28 supporting spring 27. A brake device 32 consisting of a knob 29, a brake plate 30, a spring 31, etc. is provided, and a cushion ring 33 is attached to the lower end of the lifting column 23, and the cushion ring 33 is attached to the guide vibe 26. A stopper 34 is formed which determines the upper limit position of the fan head 25 by causing the two to collide with each other.

Now, in the case of the configuration as described above, the fan head 2
1 and 2 show a state in which the fan head 25 is raised to the upper limit position, but even in this state, and also in a state in which the fan head 25 is slightly raised from the lower limit position, the strut portion 22 In particular, the thin part 22b and the neck support 24 always overlap,
This keeps the lifting column 23 covered, so the lifting column 23 is not exposed, and the narrow part 22b of the column 22 that can be seen in its place is also thicker than the lifting column 23. The step portion 22a is thinner than the support portion 22, and there is no need to consider the shape of the brake plate 30 so that the brake plate 30 is pressed into contact with the support portion 22.
It can be made into a shape similar to that of the brake plate 30 as desired, and does not require treatment with a shiny metal such as stainless steel to prevent scratches due to pressure welding of the brake plate 30, and can be made in the same color or in harmony with the support column 22, for example. It can be used in different colors, and can be used without causing any discomfort like conventional products. On the other hand, the brake plate 30 bites and presses on the lifting column 23, but in the above-mentioned case, it is covered by the narrow part 22b of the column part 22 that is in close contact with the neck support 24. In
Because of this, it is invisible to the user and can improve the appearance.

In particular, in the above embodiment, as shown in FIG.
8 ffl 11 The neck support 24 connects the head 25 to the support section 2
When the neck support 24 and the support column 22 are lowered to the lower limit position in contact with the second step 22a, the circumferential side portions of the neck support 24 and the support column 22 are substantially flush with each other, thereby further improving the appearance.

However, the present invention is not limited to the embodiments described above and shown in the drawings; therefore, the neck support 24 and the strut portion 22 may also be connected with a step, or may have a thin structure. The shaped portion is not provided on the strut portion 22 but on the neck support 24 (
The cotton-like part may be a part that is pulled up and interlocks with the strut part 22, and furthermore, the cotton-like part may be inserted into the strut part 22 and the neck support 2.
4 may be provided as a separate body rather than integrated with it, and the color etc. may be devised to produce a further design effect, and other modifications may be made as appropriate without departing from the gist of the invention.

[Effects of the Invention] As is clear from the above description, the electric fan of the present invention does not give a sense of discomfort due to the elevating column and has a good appearance without showing brake marks on the elevating column. possible, etc.
Excellent effects can be obtained.
