Description

The present invention relates to a paddle, and more particularly to a multifunctional paddle.

Paddles are equipment for small human-powered boats such as rubber boats and canoes, and paddles are rowed to move the ship forward. However, the water that had entered the ship had to be drained because water droplets flooded the ship during the process.

In the conventional patent document, for example, the "paddles" described in the following Patent Document 1, Patent Document 2, and Patent Document 3 all have an outer tube and an inner tube, and the two tubes are fitted to each other. A push-type valve is installed at the same time, and a telescopic paddle shaft that serves as an intake pump is configured, and the blade is firmly connected to the paddle shaft. As a result, it has not only the function of rowing but also the function of draining the water in the ship as a pump.

In the conventional technique described above, the inner tube of the conventional paddle is mostly inserted into the outer tube to shorten the length of the paddle shaft, but the total length of the paddle to which the blades are connected is still too long and is reserved. When it comes to paddles, it occupies space for storage. In addition, the shaft and blade of the conventional paddle have a water intake, but the paddle with the shaft as the water intake must turn the shaft downward to take water, which is the opposite of the paddle rowing operation. It was inconvenient because of this. When the bottom part of the blade was used as the water intake, it was difficult to take water by putting the wide blade in a narrow place inside the ship. Furthermore, small boats often require a spare hook rod to hook other ships or objects floating on the water, but since the hook rod needs a certain length, it should be placed on the small boat. If left unchecked, it would occupy a limited space. When mounting the hook rod on the paddle shaft, the user had to grasp the plate-shaped blade to operate the hook rod at the end of the shaft and hook other articles, which was not easy to control.
