Cuff for enhanced swimming propulsion

The present invention relates to a cuff, and more particularly to a cuff for enhancing swimming propulsion.

Swimming is not only a competitive sport, but also a practical skill that you have the opportunity to use in your life. When swimming, the famous shark shark is a high-tech swimwear that increases swimming speed. Its material mimics shark skin tissue and has tiny grooves on the surface to reduce frictional resistance. Functional swimwear. However, in the competitive sports, due to the essential meaning of the return movement, there are strict regulations on the use of high-tech swimwear. However, for lifeguards, fishermen, surfers, etc., who are not the swimmers, it is quite helpful to wear swimming equipment that can increase the swimming speed. For the average swimmer, the sense of accomplishment can be increased. Engage in willingness.

The "Swimwear and its manufacturing method" of the Republic of China Patent No. 200808210 discloses a technical feature of enhancing swimming function by using monomer particles on a swimsuit, which gives the swimsuit a hydrophilic surface and a high affinity with water. In order to improve the drainage performance, the frictional resistance with water can be reduced. However, in order to impart hydrophilicity to the surface of the swimsuit, it is simply to reduce friction. Resistance does not substantially increase the reaction force generated by swimming movements and increase propulsion.

Referring to Figure 1, the Republic of China Announcement No. 237668 The addition of a duck-footed swimming glove (1) is a duck-leg swimming glove 1 comprising five finger sleeves 10a-10e, a flap 11 between each finger sleeve 10a-10e, and The wiper blade 12 extends rearwardly from the thumb finger sleeve 10a and the finger finger sleeve 10e. The paddle 12 can cooperate with the hand stroke action to generate a reaction force during swimming, thereby improving the effect of the stroke, thereby speeding up the swimming.

However, when the swimming glove 1 is engaged in swimming, since the swimming glove 1 has a large area of the cymbal 11 and the paddle 12, the reaction force can be increased to speed up the swimming, but the wearer is affected. The activity of the finger while swimming. The use of a large area of the cymbal 11 and the paddle 12 also has the disadvantage of increasing the weight, causing the load of the wearer during the activity, and may also affect the performance of the swimming.

Accordingly, it is an object of the present invention to provide a cuff that does not affect finger movement while swimming and that increases the reaction force with minute cells.

Therefore, the sleeve for enhancing swimming propulsion of the present invention comprises a left sleeve body and a right sleeve body respectively worn on the left and right forearms of the user, and an auxiliary unit disposed on the left sleeve body and the surface of the right sleeve body. .

The left sleeve includes a left front area on the same side as the back of the hand, and a left back area on the same side of the palm, and the right sleeve includes a right front area on the same side as the back of the hand, and a right side on the same side of the palm Back area.

The auxiliary unit includes a plurality of the left rear area and the right back area The outwardly extending chamfered cylindrical unit, which enables the swimmer to increase the contact area with water when performing a stroke operation, thereby increasing the reaction force and enhancing the propulsive force of the swimming.

The effect of the invention is: wearing a close-fitting sleeve when swimming, The utility model can effectively reduce the weight load during swimming, and the user can increase the contact area with the water by the beveling cylindrical unit of the auxiliary unit when performing the water stroke action, and the user is also subjected to a larger reaction force. Therefore, it enhances the propulsion of the stroke movement during swimming.
