Abstract
The invention discloses a kayak pedal drive system which is comprised of connecting rod and other parts. Connecting rod connects fixed rod on one end and side of the metal cube on the other end. This metal cube is connected to the bottom of gear box 1 while the sides of the gear box are connected to pedals with a straight tube. Meshing gear device 1 is inside gear box 1. Bottom of the cube is linked with a straight tube. The other end of straight tube is connected to gear box 2. Meshing gear device 2 is inside gear box 2. Propellers with axis are attached to gear box two. This new configuration reduces the weight of pedal drive and also solves the problem of shock resistance of most peal drive units on the market.

TECHNICAL FIELD [001] This invention is about a pedal drive system which applied in pedal drive kayaks. A pedal drive kayak has a cockpit containing a seat and a seat of rotatable pedals to propel the kayak.
BACKGROUND [002] Most of the pedal drive units on the market are propelling kayaks by pushing pedals. There are two pairs of meshing gear within the pedal drive. Purposes of using these two geared devices are change speed through tooth ratio and power direction. One is connected with pedals and the other is connected with propellers. They are connected with a straight pole. When pushing the pedals rotating large gears connected with pedals will transmit rotation to the meshing smaller gears to enlarge speed. Smaller gear is connected to the other paired gear with straight pole. Powder will be transmitted to rotate propellers to propel kayak. This is the dominant type of pedal drive system on the market. Disadvantage of this device is less power efficiency and shock resistance. Also in order to enlarge rotation speed relatively large gears needs to be used inside the gear box which is resulted in bigger drive unit and weight. This invention is designed to solve the issues from existing pedal drive.
SUMMARY OF UTILITY MODEL [003] Purpose of this design is to increase power efficiency reduce size of the unit and shock resistance.
[004] This invention substantially has two advantages over the other pedal units. Gear device 1 and planetary enlarges rotation speed and Gear device 1 and gear device 2 changes rotation direction. The application of gear device 1 and planetary gear significantly enlarges the rotation speed instead of using the two meshing gears. It makes the whole unit smaller and lighter. Also shock resistance is improved.
[005] The other advantage is extending life of the unit. The external unit is comprised of cube, gear box 1, gear box 2 and propellers and sealed with commercial grade glue. It is completely waterproof and avoiding corrosion of both fresh water and salt water.

DESCRIPTION OF EMBODIMENTS [010] Drawings are enclosed in this article to clearly and completely depict the design. As shown in Figure 1 and Figure 2 the drive pedal unit is mainly comprised of two gear boxes, fixing rod, connecting rod, long tube and propellers. Connecting rod (1) joins fixing rod (2) and cube (20). Gear box one (3) is on top of the tube while pedals (4) are attached on the side of Gear box one (3). Straight tube (5) is on the bottom of cube and on the bottom of the straight
2019100898 13 Aug 2019 tube is gear box two (6). On the side of gear box two (7) there are propellers (7) installed. Inside the straight tube (5) there are two axis one (8) and axis two (19). Axis two (19) is on top of axis one (8). Bevel gear one (9) of the cross gear configuration is on the bottom of axis one (8). Bevel gear two (10) crossly meshes bevel gear one (9) and affixed on one end of propeller axis (11). Propellers (7) are on the other end of propeller axis (11). On top of axis one (8) inside straight tube is the sun gear (18) of planetary gear. Sun gear (18) mesh three planetary gears (15) while three planetary gears (15) also mesh gear ring (16). Three planetary gears (15) are affixed on the bottom of the carrier (21) and attached to the bottom of axis two (19). Gear ring is attached to gear box one through the fixing holes (17). On the other end of axis two is bevel gear three (12) which crossly messing with bevel gear four (13). Bevel gear four (13) is affixed on the pedal axis (12) which pedals (4) are attached on pedal axis (12).
[Oil] By using two gear boxes and straight tube the device is well sealed with commercial grade glue to avoid corruption of fresh water and salt water and hence extend life of the unit. Axis one (8) is connected to sun gear while spinning axis of three planetary gears are connected to carrier to be driven by axis two. As the teeth of the gear ring of is about four times of the sun gear and planetary gear. This device enlarges about four times of rotation speed. Planetary gear is a revolutionary device used in this patent as it significantly enlarges rotation speed within limited space compared to traditional gear.
[012] Axis two is connected to bevel gear three (12) which crossly mesh gear four (4). This spiral bevel gear enlarges about 2.5 times speed rotation speed since diameter of gear four is about 2.5 times of gear three. Axis one is connected to bevel gear one which crossly meshes gear two. This gear device reduces 10% of the speed as the driving gear of bevel gear one has smaller diameter of bevel gear two. Through gear device two, planetary gear and gear device one the rotation is enlarged 2.5 times, enlarged 4 times and reduced 0.9 times and eventually becomes 9 times of peddling speed. By changing the ratio of the gear diameter we are able to adjust the ratio of propeller rotation speed and peddling rotation speed. After water test we decide to make ratio between 8:1 and 11:1. This ratio achieves best peddling comfort and driving speed on water.
