Description

[Technical field]

[0001] The present invention relates to a toy that allows a person to slide at high speed on the surface of water. [Background technology]

[0002] Various types of playground equipment have been developed that uses buoyancy boards to move on the water surface by human power, and surfboards and bodyboards, which ride on the incoming waves and glide on the water surface from offshore to the beach at high speed, are popular among a wide range of people as standard summer leisure activities or sports. However, strong physical strength is required to move long distances from the beach to offshore by human power or to chase the incoming waves at high speed and ride the crest of the waves, so this is a high barrier to entry for elderly people and women who are less physically fit. Therefore, a playground equipment that allows anyone to move long distances from the beach to offshore with less fatigue and to glide on the water surface at high speed to catch up with the incoming waves with less fatigue is desired. Existing toys that use buoyancy boards to move on the water surface include surfboards, bodyboards, and stand-up paddleboards.

[0003] A surfboard is a toy on which a rider sits prone on the top of a buoyant board with a shape that can support the rider's entire weight and has a small wave-making resistance, and when moving offshore or chasing waves, the rider paddles the water with both arms to move the surfboard forward, and when the board catches the crest of the incoming wave, the rider stands up and steers the surfboard. When the rider stands up on the top of the surfboard, no wave-making resistance is generated by the rider, and the surfboard can be steered freely by shifting the rider's weight. However, when moving long distances offshore or chasing waves, the rider needs to paddle the water with only the strength of both arms in a prone position to move the surfboard forward, which puts a heavy load on both arms, and for elderly people and women with poor physical strength, moving offshore itself is difficult, and there are cases where the rider is unable to catch up with the incoming waves due to insufficient speed.

[0004] A bodyboard is a toy in which a rider places his / her upper body in a prone position on the top surface of a buoyant board that has a small wave-making resistance and can support the weight of the rider's upper body, and when moving offshore or chasing onshore waves, the rider paddles the water with fins to obtain a thrust greater than that of bare feet, moving the bodyboard forward, and even after catching up with the crest of the onshore wave, the rider remains in a prone position to steer the bodyboard. The rider's lower body generates wave-making resistance, so the rider cannot freely control the surfboard, but the rider's lower body is underwater, so buoyancy is generated, and as a result, the bodyboard, which is a buoyant body, can be small and easy to carry. In addition, since the rider does not stand up on the top surface of the bodyboard, the bodyboard can have a lower rigidity than a surfboard. However, in order to obtain a thrust greater than the wave-making resistance of the rider's lower body by paddling the water with fins, it is necessary to wear hard and large fins, and the corresponding muscle strength is required.

[0005] A stand-up paddle board is a toy in which a rider stands on the top of a buoyant board with a small wave-making resistance that can support the rider's entire weight, and when moving offshore or chasing waves, the rider paddles the water with a long paddle that reaches below the water surface to move the stand-up paddle board forward. This allows the rider to move comfortably on the calm water surface without generating wave-making resistance. However, since it is necessary to continue standing on the rocking stand-up paddle board and to keep paddling the water to the left and right mainly by using the muscles of the upper body, long-term operation is physically demanding for elderly people and women who are less physically strong. In addition, in order to prevent the rider from falling over due to the rocking of the stand-up paddle board caused by the influence of cross waves, the width of the stand-up paddle board needs to be wider than that of a surfboard or a bodyboard, making it inconvenient to carry.

[0006] [Patent Document 1] Japanese Patent Application Publication No. 07-196093 Summary of the Invention [Problem to be solved by the invention]

[0007] The problem to be solved is to promote the health of the nation by providing playground equipment that enables even elderly people and women with poor physical strength to glide long distances and at high speeds on the water surface with minimal fatigue. [Means for solving the problem]

[0008] The boat is composed of a front buoyancy plate with a shape that reduces wave resistance, a rear buoyancy plate with a shape that reduces wave resistance, and a connecting rail. The undersides of the front buoyancy plate and the rear buoyancy plate are each equipped with a thrust plate unit equipped with a thrust plate that tips over backward when subjected to water pressure from the front, and deploys vertically under its own weight when the water pressure from the front is eliminated, and does not deploy further forward than vertically. The front buoyancy plate is equipped with a grip on its upper surface used when moving the front buoyancy plate forward and backward, and the rear buoyancy plate is equipped with a footboard with an instep band on its upper surface used when moving the rear buoyancy plate forward and backward. One of the front and rear buoyancy plates is fixedly connected to the connecting rail, and the buoyancy plate on the opposite fixed side has a mechanism that allows it to move forward and backward along the connecting rail, making it possible to change the gap between the front and rear buoyancy plates, and the passenger kicks the rear buoyancy plate backward. The rider moves the rear buoyancy plate backward by a certain movement to deploy a thrust plate provided on a thrust plate unit of the rear buoyancy plate, and at the same time, the rider pushes the front buoyancy plate forward by utilizing the reaction force of the resistance of the water received by the thrust plate of the rear buoyancy plate, causing the front buoyancy plate to glide at high speed on the water in the forward direction, the rear buoyancy plate connected to the grip of the front buoyancy plate by the rider and the instep band also follows the front buoyancy plate and glides at high speed on the water, the rider moves the front buoyancy plate backward by a certain movement to pull back the front buoyancy plate toward himself while gliding on the water, causing the thrust plate provided on the front buoyancy plate to deploy and obtain further thrust, and the rider moves the rear buoyancy plate backward by utilizing the reaction force of the resistance of the water received by the thrust plate of the front buoyancy plate, causing the rear buoyancy plate to move forward in preparation for the next gliding action on the water by reversely moving the rear buoyancy plate. Effect of the Invention

[0009] The high-speed water gliding toy of the present invention comprehensively utilizes the major muscles of the human body to enable a buoyant board with little wave-making resistance on the water surface and its occupant to glide at high speeds, so that even elderly people and women with less physical strength can travel long distances offshore and keep up with the incoming waves at high speeds with little fatigue.

[0010] Furthermore, with the high-speed water gliding equipment of the present invention, the sum of the buoyancy of the front buoyancy plate and the rear buoyancy plate is equal to or greater than the weight of the rider, so that the rider can rest in a comfortable position when stopped and while gliding on the water by resting his / her elbows on the front buoyancy plate and his / her knees on the rear buoyancy plate.

[0011] Furthermore, in the high-speed water gliding toy of the present invention, the front buoyancy board and the rear buoyancy board are fixedly connected with a connecting pin or the like with a minimum gap, so that the rider can enjoy so-called surfing by standing up on the crest of a wave.

[0012] Furthermore, when the rider is taking a rest in a prone position on the top surface of the buoyancy board, the overall length of the toy is long, which improves stability, and when the gap between the front and rear buoyancy boards is minimized and the rider is enjoying so-called surfing in an upright position, the overall length of the toy is short, which improves maneuverability.

[0013] The stepping board with an instep band provided on the upper surface of the rear buoyancy board that constitutes the present invention allows the occupant to support the weight of the lower body with the soles of the feet to maintain a prone position, and the occupant can easily perform the actions of kicking off the stepping board while in a prone position, and pulling the rear buoyancy board that has been kicked backward back forward, all as a single continuous movement.

[0014] In addition, the grip provided on the upper surface of the forward buoyancy plate that constitutes the present invention allows the occupant to easily maintain a prone position by supporting the weight of his or her upper body with both arms, transmit the reaction force of the water resistance obtained by the rear buoyancy plate to the forward buoyancy plate to give it propulsion, give further propulsion to the forward buoyancy plate by the reaction force of the water resistance obtained by the occupant's action of pulling back the forward buoyancy plate while gliding on the water, and use the reaction force of the water resistance to pull the rear buoyancy plate forward as the occupant uses this reaction force of resistance to easily pull back the rear buoyancy plate as a series of actions.

[0015] Furthermore, the front buoyancy plate grip of this invention is provided with independent brake levers on the left and right, and when the rider pulls the brake levers, the brake plates connected by a wire or link mechanism etc. deploy independently on the left and right from the side of the front buoyancy plate forward to receive the resistance of the water, making it easy to turn left and right and to slow down when planing on the water. Incidentally, JP 07-196093, a "Patent Document" in the "Prior Art Documents" section, describes an invention in which an deployable brake plate protrudes from the bottom of a moving boat to increase water resistance and slow down the forward speed of the boat, but this is not an idea that allows the boat to turn freely left and right.

[Figure 6] This is a cross-sectional view taken along the line B-B in Figure 3. The thrust plate is in the deployed state.

[0017] 1 is a three-dimensional view of the equipment configuration of the playground equipment according to the present invention, in which the gap between the front buoyancy board 1 and the rear buoyancy board 2 is minimized. The gap between the front buoyancy board 1 and the rear buoyancy board 2 can be changed by connecting rails 3, and the rider can push the front buoyancy board 1 forward or kick the rear buoyancy board 2 backward in a prone position by grasping grips 4 and placing the soles of their feet on footplates 6. Then, by placing the tops of the rider's feet on instep bands 7 when pulling their feet in, the rear buoyancy board 2 can be easily pulled back forward. 1 indicates a fixing pin insertion hole 20 into which a fixing pin penetrating the front buoyancy plate 1 and the rear buoyancy plate 2 is inserted as a mechanism for easily fixing the front buoyancy plate 1 and the rear buoyancy plate 2 at a position with the smallest gap, but the means for easily fixing the front buoyancy plate 1 and the rear buoyancy plate 2 at a position with the smallest gap may be, for example, a method using a string or a latch instead of a fixing pin. Note that the tip of the upper surface of the front buoyancy plate 1 and the tip of the upper surface of the rear buoyancy plate 2 protrude forward more than the tip of their respective lower surfaces in order to reduce wave-making resistance when moving forward and to utilize part of the drag of the water experienced when moving forward as buoyancy. In addition, the rear end of the front buoyancy plate 1 protrudes rearward at the same angle as the tip of the rear buoyancy plate 2 in order to easily connect the front buoyancy plate 1 and the rear buoyancy plate 2, for example, by inserting a fixing pin that penetrates vertically through the front buoyancy plate 1 and the rear buoyancy plate 2 into the fixing pin insertion hole 20 when the gap between the front buoyancy plate 1 and the rear buoyancy plate 2 is set to the minimum gap.

[0018] Figure 2 is a three-dimensional view of the equipment configuration of the toy according to the present invention with the brakes activated, showing a gap between the front buoyancy plate 1 and the rear buoyancy plate 2. When the rider pulls the independent brake levers 5 on the left and right of the grip 4 while planing on water, the brake plates 8 are deployed via a wire or link mechanism 9, generating drag from the water, allowing the device of the present invention to turn left and right and decelerate.

[0019] 3 is a top view of thrust plate unit 10 according to the present invention, in which thrust plate unit 10 incorporates thrust plate 13 and components for deploying thrust plate 13 inside a downward box shape formed by top plate 11 and side frames 12. The thrust plate unit 10 is fitted and fixed into the bottom recesses of front buoyancy plate 1 and rear buoyancy plate 2.

[0020] 4 is a cross-sectional view taken along the line CC of the thrust plate unit 10 according to the present invention, in which the rotating shaft 14 for the thrust plate 13 to deploy is fixed at both ends to the side frame 12, the rotating shaft bearing 15 for the rotating shaft 14 is attached to the thrust plate 13, the deployment limit stopper 16 for preventing the thrust plate 13 from deploying in a direction more than vertically downward is attached to the top plate 11, and the tipping limit stopper 17 as a movement limit when the thrust plate 13 becomes horizontal is attached to the side frame 12. In addition, when there are multiple thrust plates 13, an opening / closing operation synchronization plate 18 connected by a shaft and a bearing 19 attached to each thrust plate 13 synchronizes the deployment operation of each thrust plate 13. The deployment limit stopper 16 is attached to the highly rigid top plate 11 because it receives a large water resistance when the front buoyancy plate 1 or the rear buoyancy plate 2 performs a rearward movement, and the tipping limit stopper 17 is attached to the side frame 12 because it does not receive a large water resistance.

[0021] FIG. 5 is a cross-sectional view taken along the line BB of the thrust plate unit 10 according to the present invention, showing a state in which the thrust plates 13 are overturned due to the resistance of water from the forward direction.

[0022] 6 is a B-B cross-sectional view of the thrust plate unit 10 according to the present invention, showing a state in which the thrust plate 13 is not subjected to water resistance from the forward direction, or a state in which the thrust plate 13 is subjected to water resistance from the rear as the buoyancy plate moves backward, and the thrust plate 13 is deployed vertically downward due to its own weight or water resistance from the rear. Note that the large water resistance that the thrust plate 13 receives when the front buoyancy plate 1 or the rear buoyancy plate 2 moves backward is received by the top plate 11 via the deployment limit stopper 16.

[0023] Figure 7 is an exploded view of the waterplane motion according to the present invention. The rider's posture is synthesized based on the cross-sectional view of A-A in Figure 1, and the arrows in the figure indicate the direction of motion of the rider's arms, torso, and legs.

[0024] A rider on the top of this high-speed water gliding toy floating on the water can assume a comfortable posture with his / her entire weight resting on the front flotation board 1 and the rear flotation board 2 by holding the grip 4 of the front flotation board 1 with both arms, resting both elbows on the front flotation board 1, placing the soles of both feet on the footboard 6 of the rear flotation board 2, and resting both knees on the rear flotation board 2, as shown in Figure 7-A.

[0025] Next, as shown in Figure 7-A, the rider lifts his hips high and assumes a forward leaning position, preparing for high-speed gliding on the water.

[0026] Then, as shown in Figure 7-C, when the rider strongly pushes backwards on the stepping board 6 attached to the rear buoyancy board 2 and at the same time strongly pushes forward on the grip 4 attached to the front buoyancy board 1, the rear buoyancy board 2 moves backwards, causing the thrust board 13 to deploy, and the reaction force of the resistance from the water is transmitted to the front buoyancy board 1 via the grip 4 and the rider, and the front buoyancy board 1 glides forward using the reaction force received through the grip 4 as propulsion. Note that as the front buoyancy board 1 moves forward, the thrust board 13 of the front buoyancy board 1 falls backwards due to the resistance of the water from the forward direction, so the wave-making resistance caused by the forward movement of the front buoyancy board 1 is negligible.

[0027] Here, if the density of seawater is ρ=1030kg / m3, and the effective dimensions of one of the propulsion plates 13 provided on the front buoyancy plate 1 and the rear buoyancy plate 2 that receives drag from the water are 10cm length and 40cm width, then the drag coefficient Cd=1.19. If the front buoyancy plate 1 and the rear buoyancy plate 2 are provided with a set of four propulsion plates 13 each, then the area over which the front buoyancy plate 1 or the rear buoyancy plate 2 receives drag from the water is S=0.16m2. If the speed at which the occupant kicks the rear buoyancy plate 2 backwards is V=2m / sec, then the drag force D(N) received from the water by the occupant kicking the rear buoyancy plate 2 backwards is D=1 / 2×ρ×Cd×S×V 2=0.5×1030×1.19×0.16×(2) 2 = approximately 392.2 N, and it can be seen that by the rider kicking the rear buoyancy board 2 backwards and simultaneously pushing the front buoyancy board 1, which has less wave-making resistance, forward, the toy of the present invention can glide at high speed across the water, using the reaction force of the resistance and the force exerted by the rider pushing the front buoyancy board 1 forward as propulsion.

[0028] Figure 7-E shows the toy of the present invention gliding at high speed on the water, and as the front buoyancy plate 1 moves forward, the rear buoyancy plate 2, which is connected to the grip 4 of the front buoyancy body 1 via the instep strap 7 and the rider, also moves forward following the front buoyancy body 1. Furthermore, as the rear buoyancy plate 2 moves forward, the thrust plate 13 of the rear buoyancy plate 2 is caused to tip backward by the resistance of the water from the forward direction, so the wave-making resistance caused by the rear buoyancy plate 2 moving forward is negligible.

[0029] Figure 7-O shows the state in which the toy of the present invention has finished gliding at high speed on the water. Since neither the gravity-deployed thrust plate 13 of the front buoyancy plate 1 nor the thrust plate 13 of the rear buoyancy plate 2 experience water resistance from the forward direction, they are deployed vertically by their own weight.

[0030] Next, as shown in Figure 7-F, when the rider pulls the grip 4 on the front buoyancy plate 1 strongly backwards, and at the same time, while leaning forward with his hips raised, pulls the instep band 7 on the rear buoyancy plate 2 strongly forwards, the thrust plate 13 of the front buoyancy plate 1 unfolds, and the reaction force of the resistance from the water is transmitted to the instep band 7 of the rear buoyancy plate 2 via the grip 4 and the rider, and the rear buoyancy plate 2 is pulled back in the forward direction along the connecting rail 3 using the reaction force received through the instep band 7 as a propulsive force, and the front buoyancy plate 1 and the rear buoyancy plate 2 return to the preparation position for high-speed gliding on the water. Note that the thrust plate 13 of the rear buoyancy plate 2 falls backwards due to the resistance of the water from the forward direction, so the wave-making resistance caused by the rear buoyancy plate 2 being pulled back forward is minimal.

[0031] By repeating the series of operations shown in Figs. 7-A to 7-F, the high-speed water gliding toy of the present invention can continuously glide at high speed on the water.

[0032] In addition, if the state of Figure 7-E is omitted and propulsion is continuously obtained to increase the gliding speed, even if the area of ​​the propulsion plate 13 that receives the resistance of the water is the same, by lowering the vertical height of the thrust plates 13 and increasing the number of them, the distance and time from when the thrust plates 13 are tilted backwards to when they deploy vertically and obtain the effect of the water can be shortened, thereby smoothly increasing the gliding speed.

[0033] Furthermore, the grip 4 of the front buoyancy plate 1 has independent brake levers 5 on either side, and when the rider pulls the brake levers 5, brake plates 8 connected by a wire or link mechanism 9 or the like deploy independently forward from the side of the front buoyancy body 1, thereby generating water resistance on the left and right sides of the front buoyancy plate 1 when gliding on the water, allowing the rider to freely turn left and right and decelerate as intended.

[0034] Here, the density of water is about 830 times that of air, and the drag of water is said to be proportional to the square or cube of the speed of an object's movement. Therefore, in order for a person to move quickly underwater or on the water with minimal fatigue, it is found that the most effective way is for the rider to rest his or her entire body on a piece of equipment that has little wave-making resistance, thereby eliminating the wave-making resistance created by the rider himself or herself.

[0035] It is also self-evident that obtaining the necessary propulsive force by comprehensively utilizing the large muscles in the human body is a way for even physically weaker people such as elderly people and women to enjoy long periods of high-speed gliding on water with minimal fatigue. The names, average sizes, and related movements of the human muscles are as follows, from largest to smallest: 1. Quadriceps (1913cc) - Leg extension 2. Gluteus Maximus (864cc) - kicking the leg back or stepping forward 3. Deltoid (792cc) Arm and shoulder movements 4. Hamstrings (776cc) - Hip extension and knee flexion 5. Pectoral muscles (676cc) - Movement of arms forward and movement of raising the body from a prone position 6. Triceps (620cc) - Pushing objects and raising the body from a prone position 7. Soleus muscle (575cc) - stabilizes the lower body when standing or running 8. Latissimus dorsi (550cc) - Pulling the body in with the arms stretched up or forward 9. Trapezius muscle (458cc) Raising the arms and shrugging the neck 10. Biceps (366cc) - bending the elbow

[0036] From the results of the previous section, it can be seen that the movement that produces the greatest force with the least fatigue is the movement that uses the quadriceps, the largest muscle, the gluteus maximus, the second largest muscle, and the hamstrings, the fourth largest muscle, to extend the hip joint and kick the leg backward.

[0037] It can also be seen that the movement of pushing the arm forward using the deltoid muscle, the third largest muscle, the pectoralis major muscle, the fifth largest muscle, the triceps muscle, the sixth largest muscle, and the trapezius muscle, the ninth largest muscle, is a movement that can generate great force with little fatigue.

[0038] In addition, it has been found that the movement of pulling the arm extended forward toward the body while bending the elbow, using the latissimus dorsi, the eighth largest muscle, and the biceps, the tenth largest muscle, is a movement that can generate great force with little fatigue.

[0039] Therefore, it can be seen that the following movements can provide great propulsion with little fatigue: kicking the legs backward while extending the hip joints, deploying the propulsion plates 13 provided on the underside of the rear buoyancy plate 2, and using this reaction force to push the arms forward to provide propulsion to move the front buoyancy plate 1 forward; moving the front buoyancy plate 1 in front backwards by bending the elbows and pulling it toward the body, deploying the propulsion plates 13 provided on the underside of the front buoyancy plate 1 to provide propulsion.

[0040] It is then clear that the most rational posture for obtaining the propulsive force required to move on the water surface through the actions described above is for the occupant to assume a prone position on the top surface of a buoyant body capable of supporting his or her own weight.

[0041] In addition, since the forward field of vision is narrow when in a prone position, it is recommended that a manual brake device be provided for turning or braking operations to avoid collisions with obstacles or other people while gliding at high speeds on the water.

[0042] In addition, by providing a mechanism for easily fixing the front buoyancy plate 1 and the rear buoyancy plate 2 at a position with the minimum gap, the front buoyancy plate 1 and the rear buoyancy plate 2 can be fixed at the position with the minimum gap when the crest of the catching wave is reached, allowing the rider to stand up and enjoy an experience similar to that of so-called surfing.
