2 is a view illustrating an internal structure of a connector of a surfboard on which an engine is installed according to an embodiment of the present invention.

As shown, the connector 54 is fixed to the engine case 44 and connects the control wire 48 and the driven wire 66.

The connector 54 is fixed to the engine case 44 and provides an inner space and a lower case 56 through which the driven wire 66 penetrates, and is screwed into an upper portion of the lower case 56 to provide an inner space. And the upper case 58 through which the control wire 48 penetrates, and the elevating motion inside the upper and lower cases 58 and 56, and accommodates and supports the ends of the control wire 48 and the driven wire 66 therein. It comprises a moving member (60).

The movable member 60 is guided and lifted in contact with the inner circumferential surface of the lower case 56.

The moving member 60 is in the form of a substantially hollow pipe and is provided with an elastic pin 64 therein and a supporting jaw 70 at the lower side thereof. The elastic pin 64 is a pin that is fixed to the inside of the moving member 60 through fastening means such as rivets and provides an elastic force in the direction of the arrow f. Since the elastic pin 64 has an elastic force, the elastic pin 64 is opened by an external force and is restored to its initial position when the external force is removed. In addition, the free end of the elastic pin 64 is bent inward to contact the neck 62 to be described later to provide an elastic force to tighten the neck 62.

Meanwhile, a known iron rod 80 is connected to the lower end of the control wire 48, and a neck 62 having a narrow shape is formed at an end thereof. The neck is a portion formed by plastic working the iron rod (80). The outer circumference of the neck 62 is in contact with the curved portion of the elastic pin 64 is provided with an elastic force in the direction of the arrow f.

In addition, the head portion 82 of the driven wire 66 has a shape like a head of a round head screw to form a locking jaw 68 and is caught by the support jaw 70 of the moving member 60.

When the control wire 48 begins to be pulled in the direction of the arrow e in the connector 54 configured as described above, the control part 48 is tightened by the elastic pin 64 because the neck 62 of the iron rod 80 is tightened. In accordance with the rise of the moving member 60 goes up. At this time, since the locking jaw 68 of the driven wire 66 is caught in the support jaw 70 of the movable member 60, the driven wire 66 also rises at the same time to further open the throttle valve (not shown). To increase the output.

As the control wire 48 rises as described above and the moving member 60 reaches the upper end of the upper case 58, the moving member 60 can no longer rise. This point is the maximum output point of the engine. . If the control wire 48 is further pulled while the engine is outputting the maximum power as described above, the neck 62 overcomes the elastic force of the elastic pin 64 and completely exits from the moving member 60. This means that if the surfer who enjoys surfing falls off the center, the control wire 48 is separated from the engine.

And it comprises a first connecting pipe 26 is installed a sealed door (36). The intake pipe 24 is a passage directly connected to a cylinder (not shown) of the engine.

Therefore, the air sucked through the inlet 20 is introduced into the cylinder through the inlet 20, the first connecting pipe 26, and the inlet 24 along the arrow i direction.

An upper portion of the first connecting pipe 26 is provided with an intrusion water induction space 42 to be described later.

On the other hand, the closed door 36 provided in the first connecting pipe 26 is a blocking means for preventing water from flowing into the intake pipe 24 when the surfboard is overturned. Since the engine (14 of FIG. 1) is located at the upper portion of the surfboard, the engine 14 is submerged when the surfboard is overturned so that water may enter the engine through the intake passage so that the air intake passage is sealed. To prevent it.

The closed door 36 is connected to the pin 38 on the inner circumferential surface of the first connecting pipe 26 to rotate about the pin 38. Therefore, when the engine 14 is normally in the normal position, the closed door 36 is waiting at the position rotated downward, and when the engine is overturned, the sealed door 36 rotates in the direction of the arrow g by gravity to block the first connecting pipe 26. .

On the other hand, the lead 40 is fixed to the lower side of the sealed door 36. The lead 40 is to add weight to the sealed door 36 to apply a greater force than when the sealed door 36 blocks the packing 28.

The inner circumferential surface of the first connecting pipe 26 is provided with a packing 28 in a loop shape. The packing 28 is a seal made of rubber material and supports the sealed door 36 when the closed door 36 is rotated in the direction of the arrow g and maintains airtightness. At this time, by the lead 40 as described above, the sealed door 36 is combined with the packing 28 with a greater force to form a seal.

The intrusion water induction space 42 is located at the lower side of the sealed door 36 when the surfboard is overturned. The intrusion water induction space 42 temporarily stores the water that penetrates between the sealed door 36 and the packing 28, and flows the water that was temporarily stored when the surfboard returns to the normal position to the inlet 20 ) To export in the direction of the arrow k. Therefore, the larger the space of the intrusion water induction space 42 can accommodate more water.

In addition, a protrusion 34 is formed at an inlet portion of the intake pipe 24. The protrusion 34 guides the water flowing through the inner wall of the first connection pipe 26 into the intrusion water induction space 42 when the surfboard is overturned, but does not flow to the intake pipe 24. will be.

As a result, in the normal state, the closed door 36 waits on the lower side of the packing 28 by its own weight and allows air to flow in the direction of the arrow i. Seal) At this time, the water penetrated through the sealed door 36 and collected in the intrusion water induction space 42 exits in the direction of the arrow k after the recovery of the normal position of the surfboard.

As shown, the configuration of the exhaust passage is the same as the configuration of the intake passage of FIG. 4, and only the intake passage has a flow of external air to the engine, but the exhaust passage has exhaust gas in the engine and the exhaust pipe 30. Induces a flow out in the direction of the arrow o through the second connecting pipe 32 and the exhaust port (22).

As a result, the surfer who rides the surfboard equipped with the engine according to the present invention can control the speed of the surfboard 10 by operating the operation lever 78 during surfing, and lose the center of the surf while falling. It is safe because the control wire 48 is separated from the engine 14.

In addition, even if the surfboard 10 is overturned, since water does not flow into the engine through the exhaust passage or the intake passage, water does not flow into the engine unless the engine is intentionally immersed in water, so that the engine is not damaged by water. .

FIG. 6 is a view showing a configuration in which the surfboard 10 is assembled in the present invention.

Referring to the drawings, it can be seen that the surfboard 10 is composed of the assembly of the two board members (86,88). That is, the board member 86 of the first half and the board member 88 of the second half of the surfboard 10 are coupled by the fastening bolt 84 and the nut 85. This is to reduce the volume when carrying the surfboard (10).

In addition, the surfboard 10 may be separated into three or more according to the embodiment, and also fastening bolt 84 and the nut 85, other fastening means may be applied.
