BRIEF DESCRIPTION OF THE DRAWINGS
The present invention will now be described in greater detail, by way of example, with reference to the accompanying drawings, in which: -Figure 1 is a longitudinally sectioned view showinga general structure of the leisure boat according to the present invention, -Figure 2 is a longitudinally sectioned view showing one example of the propeller means, Figure 3 is a longitudinally sectioned view illustrating another embodiment of the present invention, ~;
Figure 4 is a perspective view of a push button type of a tape-like switch, and ;~
Figure 5 is a plan view of ponds in a playground.
DESCRIPTION OF THE PREFERRED EMBODIM~NT ~ ~ -A general structure of the leisure boat will first be described. This boat is constructed from a boat body 1, a propeller unit 2, a steering wheel 3 and other operational equipment, and further includes a sensor mechanism for sensing its contact or collision with another boats, the shorelof~a pond~and so on to change its direction.
This leisure boat is substantially identical in the basic structure with conventional ones. That is to say, the present boat is in a round form having a diameter of about 1 : .: ~
21~)169~
to 2 meters and the boat body 1 is formed of a synthetic resin such as a FRP (a fiber reinforced plastic) for one or ~ -two boaters.
Within the boat body 1, there i9 attached a propeller unit 2 located at a position closer to its bow from the center, which is operated by the steering wheel 3 and other operational equipment to drive the boat in every direction at a speed of about 1 to 5 meters per second.
Around the boat body 1, there are provided cushions 4 formed of a suitable lightweight and high-cushioning material such as balloon tires. The cushions 4 serve to absorb shocks occurring when the boat strikes against another boats, the shore of the pond, etc. and prevent the boat from turning turtle to maintain the safety of the boaters.
The propeller unit 2 comprises a propeller 21, a propeller shaft 22, an engine 23 and other parts. The propeller shaft 22 is connected to an output shaft of the engine through a power transmission mechanism 16 comprising gears, chains, etc. to make a connection between the engine 23 and~ the propeller 21. The steering wheel 3 is communicated to a bushing 31 of the propeller shaft, which Is designed to'turn the propeller 21 to control the driving direction. -The boat is described to be driven by a propeller in -~
the instant embodiment, but may be driven by other means.
- 5 - ;:
~- ' :, ::
: -- ~
20169~2 For instance, the boat may be driven by jets. The engine used may be a gasoline engine, a d.c. motor driven by a battery, etc~ What is essential in this connection is to use an engine which allows a boat to be safely and readily driven at a given speed.
This is also true of steering equipment. The steering wheel 2 alone is referred to in the instant embodiment, but it is to be noted that there are provided additional means such as an accelerator pedal, together with safety equipment which serves to stop the propeller unit upon a release of pedaling.
Usable as the sensor 5 is a conventional piezoelectric element or a push button type of a tape-like switch (Fig. 4). The push button type of a switch is suitable for detecting pressures produced by the contact of boats, etc. with each other. On the other hand, the piezoelectric element is suitable for detecting shocks exerted by a collision between boats, etc.
When the button type of tape-like switch is used, it is preferred that it is applied circumferentially over about 3/1 of the outside of the cushion 4. Preferably, a plurality of piezoelectric elements are scattered in place.
Reference will now be made to the mechanismi for changing the direction of the boat to be propelled, when it strikes upon another boat or the shore of the pond. A
typical example of a pond is illustrated in Figure 5. The . ' ' ~ ' Z01Ç;93;2 sensor 5 is attached to the outside of the cushion 4 over the boat body 1, which comes in contact or collision with another boat, etc., and serves to detect pressures or shocks produced by such pressures or shocks. On the other hand, the propeller unit 2 is provided with a mechanism for changing its driving force, which is so connected to the sensor 5 that it is actuated to change its driving direction upon receipt of a detecting output from the sensor 5.
In the instant embodiment, the propeller unit 2 is provided with two propellers 21r and 2Q located at different angles of 90 to 180. The propeller 21r is connected to one propeller shaft 22r, while the propeller 21Q i5 coupled to the other propeller shaft 22Q, whereby the rotation of one propeller is changed ovèr to the rotation of the other propeller, thereby allowing the propeller unit 2 to change its driving direction. In other words, an engine 23 is provided on its output shaft 24 with a changeover clutch 25, .:
which is so connected to the sensor 5 that it is actuated by ~: . - -, ::
a detecting output coming froL the sensor 5.
Between the changeover clutch 25 and the propeller shaft 22r, there i9 mounted a power transmission mechanism 26r, while between it and the propeller shaft 22Q, there is provided a power transmission mechanism 26Q, whereby a ~ : `
driving force of the engine 23 is selectively transmitted to ~- ~

either one of the propellers 21r and 21Q to rotate it.
In the instant embodiment, no reference is made to .: : ::.:

the mechanism for transmitting a detecting output from the sensor 5 to the changeover clutch 25. Usable to this end is either a system for transmitting mechanically to the changeover clutch 25 pressures or shocks which the sensor 5 receives when the boat comes in contact or collision with another boat, etc., or a system for converting such pressures or shocks to an electrical output for transmission. Which of the two systems is to be selected is may be determined depending upon the structure of the changeover clutch 25.
As the thus constructed boat comes in contact or collision another boat, the shore of the pool or the like, -the sensor detects such contact or collision to provide an abrupt change of the direction of the boat to be driven. In addition, the boat is caused to turn, because the propeller unit is mounted at a position closer to its bow from the center of the boat and the bow.
An embodiment wherein a d.c. motor is used for the engine 23 will now be explained with reference to Figure 3.
A d.c. motor 23' used is reversible, and is fed with power from a chargeable battery B through a foot switch S1 and a reversible changeover switch S2. The battery 8 is placed in a chair 11 provided at the stern of the boat body 1. , . ''~ ~
A foot pedal 6 positioned on the bottom of the boat, adjacent to the propeller unit 2, serves to actuate the foot 93~:
:' -- -switch S1 to perform an on/off control and/or control an electrical resistance. The foot switch S1 is connected to ~ ;
the reversible changeover switch S2. The switch s2 receives a contact or collision signal from the sensor 5 through a manual switch 53 and changes over the direction of rotation of the d.c. motor 23' in response to the resulting d.c.
signal, thereby permitting the boat to change its direction. ;~
The function for changing the direction of the boat may beselectively immobilized by the manual switch S3.
Effect of the Invention -~
As detailed above, the leisure boat according to the ,, .
present invention changes direction abruptly and unexpectedly, moves backwardly and turns, when it strikes - - ~
against another boat, the shore of the pond, etc, thus ~ -adding unexpected, additional interest to steering.
~.
For that reason, the present boat may be permitted to strike purposely upon another boat, giving the boaters more pleasant thrills and more comfortableness than achieved ~ ~
by conventional boats which are merely designed to move - --forwardly.
In addition, such boating is best-suited for waters jammed with boats, thus offering additional advantages of making the most of ponds or pools so limited that they are~
less usable.
