Abstract

PURPOSE:To make running on the water freely and safely with simple structure merely comprising a propeller type propulsive mechanism with stamping drive like a bicycle and a direction change mechanism of this propeller propulsive drive by supporting a propeller shaft with a bearing fixed to bracket nearer the drive shaft retaining cylinder rotation side in the neighborhood of the print installing end of the propeller shaft. CONSTITUTION:A propeller 2 is driven by a horizontal propeller shaft 3 installed on the undersurface of a float 1. The propeller shaft 3 is connected with a vertical drive shaft 5 through a flexible joint 4. This vertical drive shaft 5 penetrates the center of the float 1 vertically and accommodated in a shaft holding cylinder 6 whose lower half 6a is arranged rotatable relative to the float and upper half 6b secured unmovable. The holding cylinder rotation side 6a receives rotational drive from a steering shaft 8 by a sprocket wheel 7 fitted at the top. Because a bearing 3a of the propeller shaft 3 is held by bracket 3b nearer the holding cylinder rotation side 6a, the direction of the propeller 3 changes with the rotational drive. which changes the advancing direction of the float. Thereby the water play tool can be embodied in simple structure and handled safely and easily like a bicycle because it is operated by human power.

Description

[Detailed Description of the Invention] (1) Current status of the technology Problems with water play equipment: Currently there are water skis, yachts, etc., but they are all suitable for older people, and can be used as safe and easy water play equipment for boys. There are almost no toys to be seen.

2) Means for solving the problem: Therefore, freedom is achieved through a simple structure in which a bicycle-type rhinoceros-driven propeller-type propulsion mechanism and a direction-changing FM mechanism for this propeller propulsion drive are installed on seven bodies (circular in the present invention). We provide play equipment that can be safely navigated on the water.

Embodiment: FIG. 1 is a perspective view of the entire arrangement of the present invention, and FIG. 2 is a perspective view of the main parts. 1 is a circular intermediate floating body that floats horizontally on the water. Horizontal than glass wool and resin binding on the original model
l' 7.11 form is made and combined to form the intermediate and 465
．． 2 is a prop pen of 111 selection) which is installed on the underside of the 7 body 1 and is driven by the horizontal blade U1 and the shaft 3. The propeller shaft 3 is connected to a vertical drive shaft 5 at the terminal end 4. The vertical drive shaft 5 is housed in a shaft holding cylinder 6 with a mounting number stamped thereon, with the floating body 1 perpendicularly passing through the floating body 1 at its center, the lower half 6a being rotatable with respect to the floating body, and the upper half 6b being fixed. The rotating side of the holding cylinder 6a receives rotational drive from the handle shaft 8 through the sprocket wheel 7 at its upper end.Since the bearing 3a of the propeller shaft 3 is held by the bracket 3b' on the rotating side of the holding cylinder 6a, Due to the rotational drive, the direction of the propeller 3 changes and the direction of retreat of the floating body is changed.The handle shaft 8 is held upright by a support cylinder 10 attached to a bracket 9 from the drive shaft holding cylinder fixed side 6b, and its lower end The following sprocket wheel and chain 1 on the rotating side 6a of the drive shaft holding cylinder are attached.
The F4X drive shaft 5 has a main sprocket wheel 8a connected to the main sprocket wheel 8a, and a handle wheel 8b at the upper end.The upper end of the F4X drive shaft 5 has a subordinate bevel gear, which is attached to the fixed side 6b of the holding cylinder. The horizontal shaft 14 is supported by the main shaft ψ]b of the drain 1' shaft]4, and has an autorotating Φ-type rotary mechanism 16 at both ends of the horizontal shaft 14. 18 is the waist for pedal operation [
There is no. Handle 8b, against the height of W or [ノ] 8. In addition, there is a structure of adjustment v1 that corresponds to the 1:υ interval between reflections.

4) Operation: When you step on the seat 18 and step on the bicycle, you press the pedal 16 in exactly the same way, and the propeller 2 rotates, making the 4 bodies look like they are on the water. The direction of retraction can be freely selected using the handle 8b.

5) Effects As mentioned above, this machine is operated manually up to 4F4, so it is as safe as a bicycle and can be handled easily.

Claims (1)

[Claims] There is a horizontal circular floating body, on which the following devices are installed. 1) The vertical shaft for driving the propeller passes vertically through the center of the floating body, the upper half is fixed to the floating pair, and the lower half is held by a drive vertical shaft holding cylinder rotatably attached to this, At the upper end of the park, this shaft is driven by a bicycle foot pedal shaft perpendicular to this shaft by means of a bevel gear, and at the lower end, this shaft is connected to the propeller shaft perpendicular to this shaft by a flexible shaft. The propeller shaft is supported near the propeller attachment end by a bearing fixed to the bracket on the rotating side of the drive shaft holding cylinder, and 2) the holding cylinder of the shaft of the traveling handle that determines the traveling direction of the floating body is supported by the holding cylinder on the fixed side drive shaft. It is held parallel to the cylinder by a horizontal bracket from the shaft holding cylinder, and is connected to the movable side of the vertical shaft holding cylinder section driven by a rotation transmission mechanism by a leaf chain at the lower end of the handle shaft, and has a steering handle at the upper end; ) A seat supported by a brace bracket holding the drive barrel is placed in a desired relative positional relationship with the bicycle foot pedal. The handle wheel 8b and the seat 18 each have a vertical adjustment mechanism and a distance adjustment mechanism between them.
