Description

[Detailed Description of the Invention] The present invention relates to a support device for equipment such as a box-shaped electric fan, and its purpose is to provide a device with an elevation adjustment device that has a simple structure and is easy to operate.

What is shown in FIGS. 1 and 2 is a box-shaped electric fan 1, which includes a rectangular box 2 having openings on both front and rear sides, a fan motor 3 mounted inside the box, legs 4 supporting the box, 4 and more.

Therefore, in order to adjust the elevation of the box-shaped electric fan 1 as described above, it is necessary to tilt the box body 2, and various proposals have been made in the past.

However, in many cases, as shown in Fig. 3, the legs 4, 4 have legs 5,
Attach parts 5, 6, and 6 by screwing them in, increasing the amount of screwing.

When adjusting the elevation, the front legs 5, 5 or the rear legs 6, 6
By turning the , the amount of protrusion of the legs was adjusted, and the elevation was adjusted.

Therefore, you have to turn the legs each time you adjust the height, which takes a lot of time and is troublesome.
The protrusion of the left and right legs does not match, and the fan shakes.
It could not be stably supported.

The present invention has been developed in view of the above points, and one embodiment of the present invention will be described with reference to FIGS. 4 to 8.

Reference numeral 11 designates a leg body pivotally supported on the bottom of the ceiling fan, 12 a mounting portion that accommodates a portion of the leg body, and 13 a spring piece that stably holds the leg body in the mounting portion.

The leg body 11 is composed of a pair of substrates 14 and 15, and a cylindrical boss 16 is formed at one end of one surface of one substrate 14, and a cylindrical cam shaft 17, which is a square boss on the outside, is formed at the other end of the negative surface. In addition, a pivot shaft 18 is formed at the end of the other surface relative to the cam shaft 17.

At both ends of one surface of the other substrate 15 are pins 21 and 21 that fit into the fitting holes 19 and 20 of the boss 16 and the camshaft 17.
A pivot shaft 22 is formed at the end of the pin that fits into the camshaft on the other side.

Stoppers 23, 23 for holding the leg body 11 in one state are formed on the edges of the substrates 14, 150 on the camshaft side, and a cylindrical elastic body 24 is attached to the boss 16.

The legs 1 are attached to the inner surfaces of the side walls 25, 25 of the mounting portion 12.
Notch grooves 26 and 26 are formed to serve as bearing parts for storing and supporting the pivots 18 and 22 of the leg body 11, and when the leg body 11 is housed in the mounting part 12, the substrates 14 and 15 of the leg body 11 are formed at the side edges. A rib 27, 27 is formed which abuts against.

Further, the leg body 11 is attached to the bottom surface of the mounting portion 12.
A step-shaped locking portion 28 is formed on which the stoppers 23, 23 come into contact when the spring piece 13 is raised, and a boss 29 is provided to protrude to fix the spring piece 13.

To assemble the support device having the above-described structure, after fitting the elastic body 24 into the boss 16 of one board 14 of the housing, the pins 21, 21 of the other board 15 are connected to the boss 16 and the camshaft 1.
7 into the fitting holes 19 and 20, and the leg body 11 is assembled.

Thereafter, at the same time as storing the leg body 11 in the mounting part 12,
After storing the pivots 18 and 22 in the notched grooves 26 and 26, the spring piece 13 is fixed to the boss 29 with the screw 30 to hold down the camshaft of the leg 11, and the leg 11 is pivoted to the mounting part 12. .

In this way, the leg body 11 can be easily assembled without using any tools, and the pivoting to the mounting part 12 can be done simply by pressing the camshaft 17 with the spring piece 13, easily and reliably. Can be assembled.

Since one side of the camshaft 17 is held down by the housing spring piece 13, the leg body 11 will not be inadvertently rotated due to its own weight.

When raising the twisted leg 11, the spring piece 13 is moved by the cam shaft 17.
As the spring piece 130 bends as it rotates to zero, the elastic force of the spring piece 130 becomes stronger, and the leg body does not come off from the attachment part 12 during operation.

In the further raised state, the other surface of the camshaft 17 is held down by the spring piece 13, so that the leg body 11 does not rotate inadvertently.

! In the octopus state, the stoppers 23, 23 of the legs 11 come into contact with the locking parts 28, and the protruding ends of the legs 11 are located behind the pivots 18, 18, so that the legs 11, Even when force is applied, the legs remain in the raised position.

Further, in this embodiment, the leg body 11 includes a pair of substrates 14,
15 are connected by bosses, so the legs themselves do not bend laterally and can support even heavy objects.

Also, since an elastic body is attached to the protruding end, it will not slip.

Furthermore, when using the box-shaped electric fan having the above-mentioned support device, the elevation adjustment can be performed by simply raising or lowering the legs 11, making it easy to use.

As described above, the present invention is such that a camshaft whose axis is the same as the axis of the pivot is formed on the leg body which is pivotally supported at the bottom of the device and rotates in a vertical plane, and a spring piece is brought into contact with the camshaft. Since the legs are provided at the bottom of the device, the legs are stably held at the position where they are rotated without moving due to their own weight.

When the legs are lifted up, the stoppers on the legs come into contact with the locking part at the bottom of the device, so even if force is applied to the legs, the legs do not rotate and support the device stably and safely. This has great practical effects.
