Description

[Detailed description of the device] [Industrial applications]

The present invention relates to a control grip which is provided with two propulsion devices on a self-propelled surfboard and controls an engine of the propulsion devices.

[Prior art]

Conventionally, this kind of device has not been considered, there has been no self-propelled surfboard equipped with two propulsion devices, and there has been no such control. However, the conventional self-propelled surfboard is equipped with a single propulsion device, and the surfboard engine has a transmission mechanism.
A control grip that guides the inside of the surfboard body and is integrated with the balance cable in the front part, and is provided with a balance grip at its tip, and the balance grip is provided, and the balance grip adjusts the output of one engine Had.

[Problems to be solved by the device]

As mentioned in the related art, the conventional self-propelled surfboard is only equipped with one propulsion device, and the rider performs turning operation by moving the weight while controlling the engine. However, a sharp turning ability could not be obtained with one propulsion device. The present invention has been made in view of the above problems of the conventional technology. The purpose of the present invention is to mount two propulsion devices on a self-propelled surfboard, and to provide starboard in a running state. -It is intended to provide a porting machine that can be freely controlled by one-handed operation and can obtain a sharp turning ability.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the present invention mounts two propulsion devices on a self-propelled surfboard, and simultaneously controls both starboard and port by a control grip that can freely adjust the output of starboard and port. And, the output of one port and the output of another port can be controlled with one hand.

[Action]

By horizontally pressing the control grip horizontally on the starboard (S side) hydraulic port and the port (P side) hydraulic cylinder simultaneously, both starboard engines output simultaneously, driving both propulsion units and self-propelled. The surfboard goes straight, and if you hold the control grip horizontally and further press the S side with the thumb side, the P side rises, the starboard aircraft further increases its output, and the portside aircraft decreases its output. The running surfboard makes a left turn. In addition, if you press the P side with the little finger further from the state where the control grip is held horizontally, the S side will rise, the port side aircraft will output more, the starboard aircraft will output less, and the self-propelled surfboard will make a right turn. To do.

【Example】

An embodiment will be described with reference to the drawings. As shown in FIGS. 1 and 2, the rear portion of the main body of the self-propelled surfboard 1 is recessed, and the two engine rooms 2, 2 ′ are starboard and port side. , And impeller rooms 3, 3'are reversely recessed at the bottom of each engine room 2, 2 '. Then, in each of the engine rooms 2 and 2 ', the same type of engines 4 and 4' (starboard and port) are mounted, and the drive shafts 5 of the engines 4 and 4'are mounted.
Is connected to a lower drive shaft 5 ', which penetrates the partition wall 6 and impellers 7, 7'in the impeller room 3, 3'.
Is attached to. The accelerator mechanism for controlling the rotation speed of each engine 4, 4'is such that the hydraulic transmission mechanism 8, 8'from each engine 4, 4 'penetrates the front wall of the engine room 2, 2', The inside is installed and integrated with the balance cable 9 at the front part, and it is led to the balance grip 10 at the tip of the balance cable 9, and the two grip engines 4, 4'are controlled by the control grip 11.
The output control can be performed. More specifically, referring to FIG. 3, FIG. 4, FIG. 5, and FIG. 6, the balance grip 10 main body is made of resin or light alloy. Has become. A handle 12 is provided on both sides of the control grip 11 so as to project between the grooves 13, and an end portion of the handle 12 has an arc shape. A stopper 14 is provided at the center of the inside of the control grip 11 so as to serve as a fulcrum for the stopper and the seesaw. Balance grip 10
Hydraulic cylinders 15 are provided at both corners of a bottom surface 17 recessed in a U shape, and are connected to respective engines 4, 4'mounted on the surfboard 1 main body by respective oiltight pipes 16. ing. FIG. 4 shows that the control grip 11 is horizontally gripped by the grip force of one hand, the stopper 14 is stopped by hitting the bottom surface 17, and the starboard hydraulic cylinder 15 and the port hydraulic cylinder.
Reference numeral 15 shows a change in the same stroke. By this operation, the engines 4, 4'synchronize with each other and the self-propelled surfboard 1 goes straight. FIG. 5 shows the state where the control grip 11 is horizontally held and S
By further pressing the side, the P side floats up with the stopper 14 as a fulcrum, the output of the S side engine 4 further increases, and the output of the P side engine 4'decreases, so that the self-propelled surfboard 1 becomes right. Make a turn. Sixth
The figure shows that by pressing the P side further from the state where the control grip 11 is held horizontally, the S side rises with the stopper 14 as a fulcrum, the output of the engine 4 on the P side further increases, and the engine 4'of the S side outputs. The self-propelled surfboard 1 makes a left turn when the skateboard goes down.

[Effect of device]

Since the present invention is configured as described above, it has the following effects. This device is equipped with two propulsion devices on a self-propelled surfboard, and by operating the balance grip control grip with one hand, straight-line speed control and right / left turning performance improvements were achieved. .
