Description

multifunctional paddle

This creation is related to boat paddles, especially a multifunctional boat paddle.

The oar is a tool for human-powered small boats such as rubber boats and canoes. The oar is rowed to make the boat move forward, but the water splashes into the boat while traveling, so the water in the boat must be discharged.

For example, the conventional paddles disclosed in Taiwan Patent Nos. M590565, M615306, and US 20200277034 publications all have an outer tube and an inner tube, and the two tubes are sleeved with each other and equipped with a push valve, forming a pump that serves as a pump. The retractable paddle shaft is firmly combined with a paddle, which not only has the function of paddling, but also can be used as a pump to discharge the water in the boat.

Although it is known that the inner tube of the oar can be mostly extended into the outer tube, the length of the oar shaft can be reduced, but the overall length of the oar combined with the blade is still too long, so that when it is used as a spare oar, it takes up more space for storage. In addition, although it is known that the handle or blade of the oar has a water-drawing port, if the handle is used as the water-drawing port, the handle needs to be downward to draw water, which is in the opposite direction to the paddle movement, which is inconvenient to use. If the bottom end of the blade is used as the water intake port, it is difficult for the wide blade to extend into the narrow part of the boat to draw water. In addition, spare hooks are often required on small boats to hook other boats or objects floating on the water, but the hooks must have a certain length and will occupy limited space when placed in the small boat. Furthermore, if the boat hook is to be installed at the handle of the paddle, the user can only grasp the plate-shaped paddle to operate the boat hook at the end of the handle to hook other objects, which is not easy to control.
