## Title
Splash-proof umbrella structure

## Abstract

A splash-proof umbrella structure comprises a rod passing through a slide sleeve sliding up and down along the rod. The slide sleeve is coupled to support sticks. A piece of umbrella cloth is arranged on the support sticks. The upper side of the rod has a first rod sleeve and a second rod sleeve. The first rod sleeve has first link rods coupled to the support sticks. The second rod sleeve has second link rods coupled to the first link rods. The bottom of the rod has a handle. When getting off a vehicle in rain, the user can open the umbrella in a confined space to prevent from being wetted by rainwater via sliding the slide sleeve upward to stretch the umbrella cloth bottom-up. When not in use, the umbrella cloth can be collapsed via sliding the slide sleeve toward the handle. Further, the handle can collect rainwater.

## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a splash-proof umbrella structure, particularly to a splash-proof umbrella structure, which the user can open in a confined space to prevent from being wetted by rainwater when he gets off a vehicle in rain.
2. Description of the Related Art
After parking in rain, the driver or passenger usually opens the vehicle door, reaches out an umbrella and then opens the umbrella. When the conventional umbrella is being opened, the umbrella cloth is greatly expanded bottom-up. Thus, the user has to open the vehicle door more widely to facilitate opening the umbrella. However, such a doing should make rainwater splash the user and the equipment inside the vehicle. Based on many years' experience in the related field and via persistent research and experiment, the Inventor thus proposes a splash-proof umbrella structure, which the user can open in a confined space to prevent from being wetted by rainwater.
SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide a splash-proof umbrella structure, which the user can open in a confined space to prevent from being wetted by rainwater when he gets off a vehicle in rain.
To achieve the abovementioned objective, the present invention proposes a splash-proof umbrella structure, which comprises a rod passing through a slide sleeve able to slide up and down along the rod. The slide sleeve is coupled to a plurality of support sticks. A piece of umbrella cloth is arranged on the support sticks. The upper side of the rod has a first rod sleeve and a second rod sleeve. The first rod sleeve has first link rods coupled to the support sticks. The second rod sleeve has second link rods coupled to the first link rods. The bottom of the rod has a handle able to collect rainwater. Thus is formed the plash-proof umbrella structure of the present invention. When getting off a vehicle in rain, the user can open the umbrella in a confined space to prevent from being wetted by rainwater via sliding the slide sleeve upward to gradually expand the umbrella cloth bottom-up. When not in use, the umbrella cloth can be collapsed via sliding the slide sleeve toward the handle. Further, the handle can collect rainwater.
In the splash-proof umbrella structure of the present invention, the handle further comprises a hollow cylinder and a turning knob installed below the cylinder. The cylinder and the turning knob respectively have a first through-hole and a second through-hole. When the two through-holes do not coincide, rainwater is stored in the cylinder to prevent from wetting the ground. When the turn knob is turned to make the two through-holes coincide, the stored rainwater is released via the through-holes.

DETAILED DESCRIPTION OF THE INVENTION
Refer to FIG. 1 and FIG. 2 respectively a perspective view and a structural diagram schematically showing a splash-proof umbrella structure according to the present invention. The splash-proof umbrella structure of the present invention comprises a hollow rod 1. A press-fit element 11 is arranged on an appropriate position of the rod 1 and protrudes from the interior of the hollow rod 1. A spring 12 presses against the press-fit element 11. A via-hole 13 is formed on the lower side of the rod 1. A slide sleeve 2 is inserted through by the rod 1 and able to slide along the rod 1 up and down. A plurality of support sticks 3 is coupled to the slide sleeve 2. A piece of umbrella cloth 4 is arranged on the support sticks 3. The upper side of the rod 1 has a first rod sleeve 5 and a second rod sleeve 6. A fixing element 7 is arranged on the top of the rod 1.
The first rod sleeve 5 has a plurality of first link rods 51 coupled to the support sticks 3. The second rod sleeve 6 is arranged above the first rod sleeve 5 and has a plurality of second link rod 61 coupled to the first link rods 51. A water collecting handle 8 is arranged on the bottom of the rod 1. Thus is formed the splash-proof umbrella structure of the present invention. When a user gets off a vehicle in rain, he slides the slide sleeve 2 upward to gradually stretch out the support sticks 3 and the umbrella cloth 4 bottom-up and from inside to outside. Thus, the user can open the umbrella in a confined space to prevent from being wetted by rainwater although the vehicle door is only slightly opened. When the umbrella is not in use, the slide sleeve 2 is slid down toward the handle 8 to collapse the umbrella cloth 4. Further, rainwater flows through the via-hole 13 to the handle 8 and is collected in the handle 8 to prevent from wetting the ground.
Refer to FIG. 3 and FIG. 4 a perspective exploded view and a sectional view schematically showing a handle according to the present invention. The handle 8 is arranged on the bottom of the rod 1 and further comprises a hollow cylinder 81 and a turning knob 82 arranged on the bottom of the cylinder 81. The bottom of the cylinder 81 has a first through-hole 811 and a female thread 812 extending downward. The turning knob 82 has a second through-hole 821 and a male thread 822. The male thread 822 of the turning knob 82 can be screwed into the female thread 812 of the cylinder 81, whereby the turning knob 82 is rotatably coupled to the cylinder 81. When the first through-hole 811 does not coincide with the second through-hole 821, rainwater is stored in the cylinder 81 to prevent from wetting the ground. When the turning knob 82 is turned to make the second through-hole 821 coincide with the first through-hole 811, the stored rainwater is released via the first and second through-holes 811 and 821.
Refer to FIG. 5 a diagram schematically showing the operation of a splash-proof umbrella structure according to the present invention. When a user intends to get off a vehicle in rain, he holds the handle 8 and slides the slide sleeve 2 upward to gradually stretch out the support sticks 3 and the umbrella cloth 4 bottom-up and from inside to outside. After the umbrella cloth 4 has been expanded, the pulling force of the first and second link rods 51 and 61 makes the lower rim of the slide sleeve 2 press-fit to the press-fit element 11, whereby the slide sleeve 2 is positioned well. Via the present invention, the user can open an umbrella in a confined space without opening the vehicle door too widely. Therefore, the present invention can prevent rainwater from wetting the user and the equipment inside the vehicle when the user is opening the umbrella.
Refer to FIG. 6 a diagram schematically showing that a splash-proof umbrella structure is collapsed according to the present invention. When the splash-proof umbrella structure of the present invention is not in use, the user presses down the press-fit element 11 and slides the slide sleeve 2 downward to gradually collapse the support sticks 3 and the umbrella cloth 4 top-down and from outside to inside. The rainwater on the collapsed umbrella cloth 4 flows through the slide sleeve 2 and the via-hole 13 of the rod 1 into the handle 8 to prevent from wetting the ground. The user can turn the turning knob 82 to release the rainwater stored in the handle 8.
In summary, the present invention uses a slidable slide sleeve, rod sleeves having a positioning function, and pivotally coupled support sticks and link rods to form a splash-proof umbrella structure, which can open in a confined space, and which can prevent a user and vehicle equipment from being wetted by rainwater when the user gets off a vehicle and opens an umbrella in rain.
The embodiments are only to exemplify the present invention but not to limit the scope of the present invention. Any equivalent modification or variation is regarded as not departing from the spirit of the present invention and is to be also included within the scope of the present invention.
