Description

Driving apparatus for pedal-type water rides {Driving apparatus of a pedal typed boat}

The present invention relates to a driving device of a pedal-type water playground equipment, and more particularly, a main configuration of a direction change device for changing the direction of the water playground equipment as well as a power transmission device for moving the water playground equipment injured in the water using manpower. It relates to a drive of a pedal-type playground equipment with a rotating cable applied to the element.

Since ancient times, ships have been used as an important means of transporting people and goods by sea or river. Prior to industry development, most ships were paddled by human power to gain propulsion, or wind power that gathered sails on the top of the ship was used as propulsion. It is well known that after industrial technology is developed, most ships are driven by turning a turbine with rotational power obtained by burning fuel.

On the other hand, with the recent development of leisure culture, the population enjoying leisure life is increasing regardless of season and region. In particular, in the summer season, attempts are made to enjoy not only water sports such as water skiing and jet skiing in the sea or river, but also to enjoy more pleasant play using various equipment.

Among these water rides, the rider pedals with his foot to transmit the propulsion force to the ship so that the ship is advanced, and water rides of various shapes (cannonballs) are used.

FIG. 8 is a view showing an example of a conventional water amusement ride featured in the Republic of Korea Utility Model Publication (Registration No. 20-0218490), wherein the conventional water ride 10 is a passenger on the upper portion of the hull (11) A seat 12 for sitting is provided, and a handle 13 for driving is formed in front of the seat 12. On the other hand, the lower side of the seat 12 is formed with a pedal 14 for generating a driving force while the occupant is seated on the seat 12, the rotational force of the pedal 14 to the lower portion of the hull 11 Rotating cable 16 is connected to be delivered to the provided screw 15. The rotary cable 16 is to transmit the rotational driving force of the drive shaft to the driven shaft, in the drive transmission of a small horsepower rather than a large horsepower, in the near-field drive transmission rather than the long-distance drive transmission, the drive transmission of complex power transmission direction It is known that it is mainly used in. The worm wheel 18 and the worm gear 19 are formed on the central axis of the pedal 14 so that power can be input to the rotary cable 16.

Are joined to intersect. In addition, the input gear 54 and the output gear 55 are axially coupled via a bearing or the like so that rotation of the screw case 51 may be smoothly performed. The shaft of the input side gear 54 and one end of the drive rotary cable 60 are preferably connected by a connector 64.

And also mentioned above, the outer shape of the screw case 51 of the bevel gear unit 50 is formed in the shape of the direction key of the ship, the screw case 51 is the direction key of the water play mechanism 20 according to the present invention It is configured to be. To this end, the upper middle portion of the screw case 51 is axially coupled to be rotated within the predetermined angle range from the hull 21, a case rotating means for rotating the screw case 51 is provided.

The case rotation means is a gear that is engaged with the directional key gear part 56 formed on the outer periphery of the tip protruding into the hull 21 of the screw case 51 and the directional key gear part 56 in rotational manner ( 82, a direction key rotary cable 80 for rotating the gear 82, a group of gear groups 25a and 81 and a direction control provided to rotate the directional rotation rotary cable 80; It comprises a handle 25 for. To this end, during the outer periphery of the upper end, the direction key gear portion 56 formed with the direction key gear portion 56 is gear-coupled with the gear 82 connected to one end of the rotary cable 80 for a separate direction key. The other end of the rotation cable 80 for the directional key is coupled to the gear portion 25b provided in the middle of the shaft 25a of the handle 25 as the gear 81, so that the rider adjusts the angle of the handle 25 described above. In this case, the change angle is transmitted to the direction key gear part 56 through the rotation cable 80 for the direction key so that the angle of the bevel gear unit 50 serving as the direction key is adjusted. That is, in the water play equipment 20 according to the present invention, the screw case 51 of the bevel gear unit 50 is a direction key.

The old rotary cable 60 for transmitting the driving force to the bevel gear unit 50 and the rotary cable 80 for the direction key for adjusting the rotational direction of the play equipment, respectively, the inner space of the seat body 21. Ensure that the wires (22) are properly wired so that they do not interfere with other parts such as sprockets and chains.

When briefly explaining the operating state of the water play equipment configured as described above are as follows.

The rider climbs up the hull 21 injured in water in order to use the above-mentioned water play equipment 20 and sits on the seat 23. Then, in the water play equipment according to the present invention, a separate safety device is not described, but after the safety device such as a belt, the rider stepped on the pedal 30 while holding the handle 25, the injured hull 21 on the water Allow to move forward.

That is, the power generated by the rotation of the pedal 30 is switched to the transmission direction of the power through the output gear 43 of the worm gear unit 40 is transmitted to the drive rotation cable 60. Even when the driving sprocket 33 and the driven sprocket 34 are formed by another embodiment of the present invention, the power generated by the rotation of the pedal 30 is provided with a worm gear unit provided to one side of the driven sprocket 34 ( It is transmitted to the drive rotation cable 60 through the output side gear 43 of 40.

The power transmitted to the bevel gear unit 50 through the driving rotation cable 60 rotates the screw 70 after the rotation direction is changed according to the installation direction of the bevel gear. That is, the hull 21 of the water-playing device 20 is transferred to the screw 70 by the rotational force generated by the driving of the pedal 30 in a floating state on the water to be propelled.

On the other hand, the rider manipulates the handle 25 in the direction to advance. Rotation according to the operation of the handle 25 is transmitted to the direction key gear portion 56 provided at the upper end of the case 51 of the bevel gear unit 50 through the direction key rotation cable 80, the bevel gear serving as a direction key The case 51 of the unit 50 is rotated so that the direction in which the hull 21 proceeds is adjusted.

As described above, the driving force generated by stepping on the pedal 30 of the water play equipment 20 is transmitted to the screw 70 through the worm gear unit 40 and the rotating cable 60 for driving. It is moved.

In particular, in the case where the chain 35 is formed between the drive shaft 31 and the worm gear unit 40 as in another embodiment of the present invention, as the load received from the screw 70 is transmitted to the pedal 32 is weakened, The passenger can drive the water ride 20 more easily.

In addition, the direction key for adjusting the rotational direction of the water play equipment 20 is formed integrally with the case 51 of the bevel gear unit 50 surrounding the front end of the rotating shaft of the screw, protruding from the lower portion of the hull 21 The portion is reduced, so as not only to facilitate the transport of the play equipment 20 is also advantageous in terms of aesthetics of the lower portion of the hull.

As described above, the water rides constituted by the present invention have less load than the water rides according to the prior art because the load received by the screw hitting the water flows to the handle, so that the rider can operate the water ride more easily. In addition, since the direction key for adjusting the direction of the play equipment is formed integrally with the case of the bevel gear unit surrounding the front end of the rotating shaft of the screw, the protrusion structure of the lower part of the hull is simplified to facilitate the transport process of the play equipment There is a great advantage that the lower aesthetics of the hull are advantageous.
