WARNING DEVICE DISPOSED ON A TOP OF AN UMBRELLA
A warning device disposed on a top of an umbrella comprises a base, an LED unit and a transparent cap. The base is formed in a lower end thereof with an accommodation space flexibly expanding downwards, on an upper end of the base is formed an outer threaded portion, and in a top surface of the upper end of the base is formed a concave space for placement of the LED unit. The transparent cap is formed in a lower end thereof with an inner threaded hole to be screwed with the outer threaded portion of the base, and a concave portion is formed upwards from the inner threaded hole. The transparent cap is further formed with plural protrusions on an upper end thereof.
1. Field of the Invention
The present invention relates to a warning device, and more particularly to a warning device disposed on a top of an umbrella.
2. Description of the Prior Art
To prevent collision accident at night, on various products (such as clothes worn by the user at night or when the sight is dim or an independent warning device assembled on a product) are installed a warning device. The existing warning devices include optimal function forms according to the to-be-assembled products for exerting the optimal safety warning effect.
However, the existing warning devices assembled on the various products all have a single function in use and cannot be used for multi-functions, so that one warning device can only cooperate with a single product.
SUMMARY OF THE INVENTIONThe primary objective of the present invention is to provide a warning device disposed on a top of an umbrella to solve the problem that the existing warning devices only have a single function.
To achieve the above objective, a warning device disposed on a top of an umbrella in accordance with the present invention comprises a base, an LED unit and a transparent cap.
The base is formed in a lower end thereof with an accommodation space flexibly expanding downwards, on an upper end of the base is formed an outer threaded portion, and in a top surface of the upper end of the base is formed a concave space for placement of the LED unit.
The transparent cap is formed in a lower end thereof with an inner threaded hole to be screwed with the outer threaded portion of the base, a concave portion is formed upwards from the inner threaded hole, and the transparent cap is formed with plural protrusions on an upper end thereof.
Further, the accommodation space is axially formed on an inner surface thereof with plural spaced flanges which offer an anti-slip function when a protruding portion at the top end of the umbrella is inserted into the accommodation space.
Further, the base is pre-formed with a hole for installation of a ring. With the above structure, the warning device of the present invention is mounted on the protruding portion at the top end of the umbrella through the accommodation space in the base thereof, so that the LED unit can be turned on to flash intermittently for offering a safety warning function. In addition, when the umbrella which is assembled with the warning device of the present invention on the top end thereof is used as a crutch, the plural protruding portions on the transparent cap can offer an anti-slip function with respect to the ground, Hence, it can be found that the warning device disposed on the top of the umbrella can offer multi-functions.
The present invention will be clearer from the following description when viewed together with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiment in accordance with the present invention.
Referring to
The base 1 is formed in a lower end thereof with an accommodation space 11 flexibly expanding downwards (as shown in
The LED unit 2 is an illuminating element to be assembled in the concave space 14 in the upper end of the base 1. As shown in
The transparent cap 3 is formed in a lower end thereof with an inner threaded hole 31 to be screwed with the outer threaded portion 13 of the base 1 (as shown in
Referring to
As shown in
In addition, as shown in
As shown in
To summarize, the warning device in accordance with the present invention has the following advantages:
-
- 1. The warning device can serve as a night safety warning device when being assembled on the top end of the umbrella to.
- 2. The warning device can offer an anti-slip function through the protruding portions on an end thereof when the umbrella on which the warning device is assembled is used as a crutch.
- 3. The accommodation space formed in the base of the warning device is applicable to different specifications of protruding portions at the top ends of different umbrellas.
- 4. After being disassembled from the top end of the umbrella, the warning device has the advantages of easy operation and convenient to carry and can serve as a normal illuminating device, so that the warning device can offer multi-functions in use.
While we have shown and described various embodiments in accordance with the present invention, it is clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
