JPH0835213A - Indicating member of cone-shaped indicator - Google Patents

Abstract

PURPOSE:To attract the attention of people by a wind-induced rotary motion and enhance dramatically an indication function of a cone-shaped indicator by installing a bearing which supports an external cylinder rotatively to an inner peripheral surface of the external cylinder and installing a blade which rotates the external cylinder to an outer peripheral surface. CONSTITUTION:A bearing 6 is installed to an inner peripheral surface of an exterior cylinder 5 which is outwardly fitted in a cone-shaped part 3 of a cone- shaped indicator 1, thereby making the exterior cylinder 5 turnably. Then, a blade 8, which receives wind, is installed to the outer peripheral surface of the exterior cylinder 5. Furthermore, the outside surface of the exterior cylinder 5 is coated with fluorescent paint or the like and finished in colors or patterns which are attractive. This construction makes it possible to greatly enhance safety by urging a driver of a vehicle or people around to pay attention to the indicator.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rotary display unit of a cone type display which is installed on a road or various construction sites and is used to call attention to a vehicle or a person approaching.

[0002]

2. Description of the Related Art A conventional cone type display device is made of synthetic resin and has a structure in which a cone portion is integrally provided on the upper surface of a rectangular base or the like. Are installed around roads and construction sites to alert people and vehicles to approach and approach.

[0003]

By the way, the conventional cone type display is simply colored in red,
For this reason, it may not be noticeable depending on the color around the installation site, and since it does not move at all in rainy weather or at night, it is also not noticeable in this case, and the function as an indicator is extremely low. There's a problem.

SUMMARY OF THE INVENTION An object of the present invention is to provide a rotary display which can attract the attention of a person by rotation due to wind and can significantly improve the display function of a cone type display.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention relates to an inner peripheral surface of an outer cylinder which is externally fitted to the conical portion of a cone type display, and externally fitted to the conical portion. A bearing for rotatably supporting the outer cylinder is provided, and a blade is provided on the outer peripheral surface of the outer cylinder to rotate the outer cylinder by receiving wind.

[0006]

When the outer cylinder is externally fitted into the conical portion of the cone type indicator, the outer cylinder is rotatable by the bearing, and the outer cylinder rotates when wind is received by the blades provided on the outer peripheral surface. Therefore,
In the cone type display, the outer cylinder rotates in response to the wind, attracting the attention of others and alerting them.

[0007]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

As shown in the figure, the cone type display 1 has a structure in which a cone portion 3 is provided on a base portion 2 using a synthetic resin, and is generally colored red.

The rotary indicator 4 mounted on the conical portion 3 of the cone type display 1 has an outer cylinder 5 formed into a truncated cone shape which is fitted on the conical portion 3, and an outer cylinder 5 of the outer cylinder 5. Bearings 6 and 7 provided on the upper and lower ends of the inner peripheral surface and externally fitted to the conical portion 3 to rotatably support the outer cylinder 5, and a plurality of wind-receiving blades provided on the outer peripheral surface of the outer cylinder 5. 8 and.

The outer cylinder 5 and the blade 8 on the outer peripheral surface are integrally formed of, for example, synthetic resin, and the blade 8 has a shape, a number and a shape so that the outer cylinder 5 is rotated by receiving wind. The position to be provided is set.

It is preferable that the bearings 6 and 7 are of a non-lubricating type, and the structure is such that a rolling element is incorporated between an inner ring and an outer ring, or a spherical body is used as a holding base from the base. One that is rotatably supported so that a part thereof protrudes may be one that is arranged and fixed in the circumferential direction of the inner peripheral surface of the outer cylinder 5. The point is that the inner peripheral surface of the outer cylinder 5 contacts the cylindrical portion 3. Instead, it may be any one that can support the outer cylinder 5 with a light force.

Further, the outer cylinder 5 has an easily noticeable color and pattern such as finishing its outer surface with a fluorescent paint or sticking a fluorescent sticker, and the cone type display 1 is stable against wind. A ring-shaped weight may be provided on the lower portion of the outer cylinder 5, or the weight of the bearings 6 and 7 may be increased.

Although the outer cylinder 5 is a truncated cone, the outer cylinder 5 covers the entire conical portion 3 from above.
It may be formed in a conical shape.

The rotary display body of the present invention is constructed as described above, and the rotary display body 4 is externally fitted to the conical portion 3 of the cone-shaped display device 1 installed on a road or a construction site.

In the rotary display 4, the outer cylinder 5 has a bearing 6,
Since the outer cylinder 5 is fitted onto the conical portion 3 through the outer cylinder 5, and the outer cylinder 5 is provided with the wind-receiving blades 8 on its outer peripheral surface, the outer cylinder 5 is rotated by receiving natural wind or wind generated by passage of wheels. This rotation makes it possible to draw people's eyes and call attention.

When the cone type display 1 is removed, the rotary display body 4 is pulled out from the conical portion 3 and the display bodies 4 are sequentially fitted to each other so that the rotary display body 4 can be stored in a low volume.

[0017]

As described above, according to the present invention, the outer cylinder rotates when the wind is received while being fitted on the conical portion of the cone type indicator, so that the cone type indicator becomes extremely conspicuous. , It is possible to call attention to the driver of the vehicle and the surrounding people, and the safety can be greatly improved.

Further, since the outer cylinder rotates in response to wind, it does not require any power source or the like and is economically superior.
