Description

[Detailed Description of the Invention] The present invention relates to an electric fan whose main body moves up and down on a pipe-shaped support, and in particular provides a simple device that prevents the electric fan main body from rotating relative to the support when blowing air.

The present invention will be described below with reference to the drawings. Reference numeral 1 denotes a support that is suspended from a base 2 and has a circular pipe shape.

Reference numeral 3 denotes a fan body consisting of a fan, guard 4, motor 5, etc., which is supported via a neck piece 6 at the front end of a holder 7 that engages with the support column 1 in a vertically movable manner, and can be rotated and rotated in the same manner as before. Elevation is adjustable.

The holder 7 is composed of a molded body divided into left and right halves,
A through hole 8 is formed at the rear end of the holder 7, through which the support column 1 passes, allowing the holder 7 to be mounted on the support column 1 in a vertically movable manner.

Reference numeral 9 denotes an engager having an insert 10 whose one end is pivotally supported on the rear end of the holder 7 so as to be vertically movable and through which the support post 1 passes; reference numeral 11 engages the insertion edge 12 of the insert 10 of the engager 9 with the support support 1. It is a spring body that acts to

Reference numeral 13 denotes an engagement release lever that is rotatably supported by the holder 7 and has one end protruding from the lower opening 14 of the holder 7, and the other end of the lever 13 is located above the tip of the engagement element 9. .

Reference numeral 15 denotes a spring body that causes one end of the lever 13 to protrude from the opening 14 of the holder 7 and biases the other end of the lever 13 away from the tip of the engagement member 9.

Reference numeral 16 denotes an elastic body that performs a braking action and is attached to the side of the lever 13 facing the column 1. When the lever 13 is not in operation (FIG. 2), it is pressed against the column 1 by the lever 13, and When the lever is rotated (FIG. 3), it is detached from the support column 1.

17 is a speed control pull switch mounted in the holder 7, and 18 is a pull string for the pull switch.

Next, to explain the function of the holder 7, first, when the holder 7 is positioned relative to the support column 1 (Fig. 2)
The lever 13 has one end projected from the opening 14 of the holder 7 by a spring body 15, and the other end spaced apart from the engaging member 9.

Therefore, the engagement element 9 has its insertion 10 and edge 12 abutted against the support 1, so that the holder 7, that is, the fan body 3, is brought into contact with the support 1.
It will be positioned against.

At this time, if the fan main body 3 blows air oscillatingly or at an angle to the holder 7, in the conventional case, the holder 7 may rotate from the support 1 due to the blowing force of the fan, that is, the propulsive force, and the set air blowing become unable to do so.

However, in the present invention, since an elastic body 16 that performs a braking action is attached to the side of the lever 13 facing the column 1,
As mentioned above, it is possible to prevent the holder 7, that is, the fan main body 3, from rotating relative to the support column 1 due to natural swinging or air blowing.

In addition, when the electric fan main body 3 is forcibly rotated by hand or the like, since the brake piece is formed of an elastic body, it can be rotated against the pressing force.

Next, when moving the main body 3 up and down with respect to the support 1, when the lever 13 that can protrude from the opening 14 of the holder 7 is pushed up against the spring body 15, the other end of the lever 13 pushes down the tip of the engager 9. Therefore, the insertion edge 12 of the engaging element 9 comes off from the support column 1, allowing the holder 7 and main body 3 to move up and down freely.

At this time, the elastic body 16 that performs the braking action is separated from the column 1 by the rotation of the lever 13, so that it does not interfere with the vertical movement of the main body 3'.

When the lever 13 is released, the lever 13 is moved away from the engaging member 9 by the spring body 15, so that the holder 1 can be fixed in that position as described above.

As described above, the present invention consists of a pipe-shaped support that is erected from a base, a holder that is fitted into the support with a through hole so that it can move up and down, and a fan motor guard that is supported by the holder and blows air. an engaging element which is pivotally supported on the holder so as to be movable up and down and has an insertion part; a spring body which urges the engaging element to engage with the support column; a rotatable lock release lever whose other end protrudes and engages with the engaging element; a spring body which biases one end of the lever to protrude from below the holder; It is equipped with an elastic body that is press-contacted to the column and released from the press-contact to the column when the lever is actuated.It has a simple structure and can prevent the main body from swinging and rotating relative to the column when blowing air. , the main body can be moved up and down relative to the support column smoothly, and is useful in practice.
