Abstract
Description
- The present invention relates to a movable toy, and more particularly to an on-water/underwater movable toy which can cruise both on-water and underwater.
- The conventional submersible toy is a submarine-shaped toy, for example, a toy that cruises on-water and is capable of brief and repetitive submerging and surfacing underwater. In the Patent Document 1 is proposed a submersible boat in a spindle form, the operation method of which is to utilize the reaction force that is generated when the water in the boat is pumped out.
- Patent Document 1: Laid-open Patent Publication
No. 2000-262771 , FIG. 3 on Page 1 - Typical conventional submersible on-water/underwater movable toy takes the form mostly of a spindle-shaped submarine. The submarine-type structure would involve projection of a plurality of elevators and horizontal planes against the side wall of the hull. This form was especially designed for underwater cruising, which was thus not optimal for high-speed on-water cruising like a leisure boat and a racing boat.
- On the contrary, underwater cruising of a movable toy that takes the form of a leisure or racing boat would require mounting of horizontal plane and elevator on the side of the hull, which horizontal plane and elevator must be long enough to achieve the benefits necessary for underwater cruising. Installation of such a long elevator to a hull having an already great horizontal width would, however, lead to much greater horizontal width of the entire boat, resulting in an undesirable designing.
- To solve the above-mentioned problems, the present invention is intended to provide an on-water/underwater movable toy which has the optimal form for high-speed on-water cruising like a leisure boat and a racing boat, and which is also capable of cruising underwater.
- The on-water/underwater movable toy according to the present invention comprises: a hull having a boat-shaped deck board that is in close contact with a boat bottom without any clearance therebetween; a screw mounted under said boat bottom; a ladder controllably mounted on said boat bottom; a recess prepared on a boat stern, the recess getting deeper toward the direction of movement; and an elevator disposed at the lower end of said recess, having a shape similar to that of said recess, and being controllably pivotable about a horizontal axis defined by the two elevator-holding axis supports projecting downward from the rear portion of the boat bottom.
- The movable toy cruises on water when said elevator is horizontal in relation to the hull, while the toy can cruise underwater when the rear end of said elevator is brought pivotably downward in relation to the hull.
- The toy can have a groove which is cut all around the hull, between said deck board and said boat bottom, except the rear portion thereof. Said recess can take such a form as to get greater in width toward the stern side and smaller in width toward the bow side, and said elevator can take an isosceles trapezoid form.
- Said elevator, said ladder and said screw are remotely operable by radio control.
- The on-water/underwater movable toy according to the present invention comprises: a hull having a boat-shaped deck board that is in close contact with a boat bottom without any clearance therebetween; a screw mounted under said boat bottom; a ladder controllably mounted on said boat bottom; a recess prepared on a boat stern, the recess getting deeper toward the direction of movement; and an elevator disposed at the lower end of said recess, having a shape similar to that of said recess, and being controllably pivotable about a horizontal axis defined by the two elevator-holding axis supports projecting downward from the rear portion of the boat bottom. This configuration enables less complicated structure of the movable toy, which has the optimal shape for high-speed on-water cruising like a leisure boat and a racing boat, and which is also capable of cruising underwater.
- The movable toy cruises on water when said elevator is horizontal to the hull, while the movable toy can cruise underwater when the rear end of said elevator is brought pivotably downward in relation to the hull. This configuration enables the movable toy to be easy-to-navigate and to have the optimal shape for high-speed on-water cruising like a leisure boat and a racing boat, as well as to cruise underwater.
- The groove which is cut around the hull, between said deck board and said boat bottom allows for more stable underwater cruising.
- Said recess can take such a form as to get greater in width toward the stern side and smaller in width toward the bow side, and said elevator can take an isosceles trapezoid form. This configuration facilitates generation of greater driving force.
- Furthermore, said elevator, said ladder and said screw being remotely operable by radio control, the movable toy can be free to surface and submerge, and free to cruise on-water and underwater, even when the operator of the toy is staying at a distance therefrom.
- An embodiment of the on-water/underwater movable toy of the present invention is described with reference to the drawings.
- FIG. 1 is an oblique view of the entire on-water/underwater movable toy according to the embodiment;
- FIG. 2 is a side view of the on-water/underwater movable toy according to the embodiment;
- FIG. 3 is a magnified view of the recess of the on-water/underwater movable toy according to the embodiment;
- FIG. 4 is a magnified view of the elevator of the on-water/underwater movable toy at the time of on-water cruising according to the embodiment;
- FIG. 5 is a magnified view of the elevator of the on-water/underwater movable toy at the time of underwater cruising according to the embodiment; and
- FIG. 6 is a block diagram relating to the radio-controlled operation of the on-water/underwater movable toy according to the embodiment.
- First of all, the embodiment will be described with reference to FIG. 1. An on-water/underwater
movable toy 2 of the embodiment of the present invention is provided with arear wing 6 supported by two supportingmembers 8 at the rear portion of adeck board 4 having a boat shape. A recess 12 comprising arecess surface 16 and aninternal surface 14 is provided in between the two supportingmembers 8 at the rear portion of thedeck board 4. The recess 12 is defined by therecess surface 16 and theinternal surface 14; the recess 12 being smaller in width toward therecess surface 16, and greater in width toward the rear end thereof along theinternal surface 14. Anelevator 34, not depicted in FIG. 1, is configured to have an isosceles trapezoid shape, a shape similar to that of the recess 12. Agroove 10 is cut all around thedeck board 4, between saiddeck board 4 and saidboat bottom 18, except the rear portion thereof. - Next, a
boat bottom 18, which is the reverse side of thedeck board 4, is described with reference to FIG. 2. Theboat bottom 18 has a center board 20 projecting vertically downward from the longitudinal center thereof. Ascrew housing 22 is mounted adjacent to the center board 20 and backward against the direction of movement. Ascrew axis 24 is installed at the rear end of thescrew housing 22 to project backward therefrom, and ascrew 26 is rotatably mounted at the end of saidscrew axis 24. - A
ladder 30 is mounted in a controllably rotatable manner, still further backward on the boat bottom with a predetermined distance from thescrew 26. Twoskegs 28, projecting from theboat bottom 18 and located across thescrew 26 and theladder 30, can enhance the water flow management. - An
elevator 34 is mounted still further backward on the boat bottom with a predetermined distance from theladder 30, such that theelevator 34 can be controllably inclined. Theelevator 34 is inclinably pivotable between two elevator-holding axis supports 32 projecting downward from the rear portion of theboat bottom 18. Theelevator 34 comprises anelevator bottom plate 36,elevator side plates 38 that are vertically arranged on both sides of theelevator bottom plate 36, and aretainer plate 40 that is in communication with, and at a certain angle to, theelevator bottom plate 36. - The
elevator 34 is inclinably pivotable between the elevator-holding axis supports 32, theelevator 34 being driven with a servomotor embedded inside the hull. Adrive shaft 41 of the servomotor is projectingly mounted in the center of theinternal surface 14 of the recess 12, as depicted in FIG. 3, to be combined with acrank 42. An aperture is prepared at an end of thecrank 42 opposite to the other end where thedrive shaft 41 is combined, the aperture engaging with arod 44. Arod cover 46 attached to therod 44 is pinned to theelevator side plate 38. Thecrank 42 can also be joined to theelevator side plate 38 by therod 44 alone and without therod cover 46 being attached. - With reference now to FIGS. 4 and 5 that depict the operation of the
elevator 34, the operation of the on-water/underwatermovable toy 2 of the embodiment of the present invention will be described. - The
screw 26 rotates in response to the signal from a transmitter, propelling the on-water/underwatermovable toy 2 forward, and the direction of movement changes as theladder 30 shifts its direction. - As the servomotor embedded in the hull rotates to move the outer end of the
crank 42 upward until theelevator 36 is horizontal to the hull by way of therod 44 and therod cover 46, the driving force is directed upward and forward (direction A) in relation to the hull's horizontal direction. Then, the boat bow moves upward in relation to the hull's horizontal direction to bring the hull to the on-water cruising operation, which is a horizontal operation like regular vessels. - On the contrary, as the servomotor embedded in the hull rotates to move the outer end of the
crank 42 down until the rear end of theelevator 36 is brought pivotably downward in relation to the hull by way of therod 44 and therod cover 46, the driving force is directed downward and forward (direction B) in relation to the hull's horizontal direction. Then, the boat bow moves downward in relation to the hull's horizontal direction to bring the hull to the underwater cruising operation. - The on-water/underwater movable toy of the present invention can thus have the optimal shape for high-speed on-water cruising like a leisure boat and a racing boat, and at the same time, can cruise underwater and on-water.
- With reference now to FIG. 6 that shows a block diagram, the radio-controlled remote operation of the on-water/underwater
movable toy 2 of the present invention will be described. - FIG. 6 is a block diagram illustrating the configuration of the on-water/underwater
movable toy 2 of the present invention, the on-water/underwatermovable toy 2 comprising a steering anddriving section 43, ascrew driving section 44, anelevator driving section 46, and acontrol section 50 that controls theladder 30, thescrew 26 and theelevator 36. - The on-water/underwater
movable toy 2 further comprises: anantenna 56 that catches a control signal from atransmitter 54; asignal receiving section 48; acontrol section 50 that controls each driving section in response to said control signal; a steering and drivingsection 43 that drives, in response to a control signal from saidcontrol section 50, aladder 30 mounted in the hull; ascrew driving section 44 that drives ascrew 26 in response to the control signal from saidcontrol section 50; anelevator driving section 46 that drives anelevator 36 designed to switch-control the on-water and underwater cruising operations; and apower section 52. - FIG. 6 further illustrates the embodiment of the on-water/underwater
movable toy 2 of the present invention. The steering and drivingsection 43 and theelevator driving section 46 comprise a servomotor, respectively, and thescrew driving section 44 comprises a conventional electric motor. - Operation of on-water cruising of the
movable toy 2 is controlled in the following manner: the transmitter sends out a control signal, which causes the receivingsection 48 to send out another control signal through thecontrol section 50 to theelevator driving section 46, thereby pivotably lifting the rear end of the elevator bottom plate 36 (adjacent to the retainer plate 40) of theelevator 34. - Operation of underwater cruising of the
movable toy 2 is controlled in the following manner: the transmitter sends out a control signal, which causes the receivingsection 48 to send out another control signal through thecontrol section 50 to theelevator driving section 46, thereby pivotably bringing down the rear end of the elevator bottom plate 36 (adjacent to a retainer plate 40) of theelevator 34. - The on-water/underwater movable toy of the present invention can thus have the optimal shape for high-speed on-water cruising like a leisure boat and a racing boat, and at the same time, can cruise underwater and on-water.
- While the embodiment of the present invention has been described and shown as a configuration in which a
groove 10 is cut all around thedeck board 4, between said deck board and said boat bottom, except the rear portion thereof, it is also within the design variation of the present invention to arrange the configuration without thegroove 10.
