Among them, water sports can give people a feeling of new and exciting feelings, and their market size has gradually grown, and they are widely combined with many cultural festivals. Rowing is one of the most popular water activities, with ordinary boats and canoes being the most common.

Ordinary small boats have a large volume and require two hand paddles. Each hand paddle has only one end with a paddle and the other end for holding. When in use, the middle section of the paddle rod is supported on both sides of the boat as a fulcrum, and both hands simultaneously rotate the grip end of the paddle rod to drive the other end of the blade to push the boat forward.

The size of the canoe is relatively small, there is no space for the two hand paddles to support and rotate, so only one hand paddle is used. The difference is that the paddles are equipped with blades at both ends, and the user holds Holding the middle section of the paddle, use the self as the hand paddle to rotate the fulcrum and alternately make the blades into the water, thereby pushing the canoe forward.

It is conceivable that the canoe's hand paddles only once at one end. When the blade pushes the water, the force and speed that can be generated are limited, and the hand paddle needs to have a certain length to contact the water surface on both sides of the canoe, and it is also less convenient to carry.

Accordingly, it is an object of the present invention to provide a hand paddle that can be double stroked with either a single side paddle or a double paddle.

Therefore, the hand paddle of the novel double stroke mode includes a rod body, a reinforcing body and a two paddle body.

The overall shape of the rod body is generally U-shaped, and includes a connecting section which is located at the front and has an arc shape, two hand-held sections respectively extending backward and downward from both ends of the connecting section, and two hand-held sections respectively An extension that extends downward and outward. The spacing of the hand segments is greater than the width of the upper body of a user.

The reinforcing body includes a front reinforcing section connecting the two ends of the connecting section, and two side reinforcing sections extending rearward and downward from the two ends of the front reinforcing section, respectively, and the ends are respectively connected to the side reinforcing sections of the extending sections.

The paddles respectively include a paddle rod for connecting one of the extension segments, and at least one paddle coupled to the paddle bar.

The effect of the novel is that, by the U-shaped extending body, the hand-drawing paddle of the novel double-draw mode can selectively draw water with a single-sided paddle, or both sides of the blade simultaneously enter water to increase the forward thrust. It can effectively increase the speed and meet the needs of different occasions.

The equivalent modification and adjustment methods are well-known in the art, and therefore will not be described here.

Thus, when the user holds the rod 1 (see Figure 9) and backwards When pushing the water body, the blades 31 can be unscrewed by the resistance of the rear water body to the stroke angle, and the water is pushed by the maximum surface area to maximize the thrust of the stroke; after the water is pushed, the rod body is pulled forward. 1. In preparation for the next push of water, the blades 31 are rotated by the resistance of the front water body to the force reduction angle, and at this time, the blades 31 can contact the front water body with a minimum area, and greatly reduce the push. Water resistance when water.

Referring to Figures 10 to 12, each adjustment member 34 corresponds to a paddle. The leaf 31 is pivotally connected to the back water surface 320 of the paddle 32 and is rotatable relative to the paddle 32 to a collapsed position and an adjusted position.

In the folding position, the adjusting member 34 is as shown in FIG. 10 and 11 extends along the length direction of the paddle 32; in the adjusted position, the adjusting member 34 is outwardly spiraled out as shown in FIG. 12 and protrudes from the back surface portion 320, at this time, when the paddles When the leaf 31 is rotated toward the pulling position, it will respectively abut against the two ends of the adjusting member 34 and sandwich an intermediate angle between 0 and 180 degrees. In this embodiment, the intermediate angle approaches 120 degrees.

In this way, the adjustment member 34 can be maintained at the time of normal use. Positioning, but when the user wants to retreat the canoe and push the water in the manner of swiping the rod 1 forward, the adjusting member 34 can be screwed out to the adjusted position, at this time When the blade 31 is rotated by the resistance of the front water body, it interferes with the adjusting member 34, is fixed at the intermediate angle, and cannot be completely rotated. Thus, the blades 31 can still push the front with a large enough area. The water body is convenient for the user to use under special circumstances such as obstacles.

Therefore, this embodiment can achieve the same work as the above embodiment. In addition to the effect, it is also possible to adjust the water pushing area of the blades 31, and to push the water at the maximum area to maximize the thrust when advancing, and to reach the water body with a minimum area when the water is not pushed, thereby achieving the labor-saving effect, and taking into consideration the backward movement Practicality, more functional.
