Boat for the aquatic board type water leisure

Abstract

Since the body of the present invention is shaped like a waterboard, the user can move forward on the water while lying face down on the top of the body with their buttocks, thighs, and abdomen in close contact, thereby preventing water safety accidents where the user falls into the water. Furthermore, because it consists of a simple configuration of a body and a motor, users are not burdened by purchase costs, allowing for widespread adoption. Additionally, safety during use is greatly ensured as the device does not sink due to the buoyancy space provided inside the body. Moreover, since the propulsion screw that propels the body through rotation is protected by a first protective net and a second protective net covering its perimeter, it is possible to prevent foreign matter from the water or surface from being transmitted to the propulsion screw, thereby preventing the screw from malfunctioning or the propulsion screw from stopping its rotational movement due to foreign matter getting entangled in it during forward movement. Furthermore, by the user twisting the body by holding the handles with both hands, as if riding a motorcycle, or by rotating the handles left and right, as if riding a jet ski A waterboard-type water leisure boat is disclosed that allows steering to the left and right, thereby significantly improving usability and convenience, and enabling women and teenagers with less physical strength to easily enjoy it.

Description

Technology Field

[0001] The present invention relates to a waterboard-type water leisure boat, and more specifically, to a waterboard-type water leisure boat that allows one to enjoy water leisure by moving forward on the water surface by pressing a push switch provided on the handles while lying prone on a body made of a waterboard type and gripping both handles with both hands, and rotating a propulsion screw that is rotated by the power of a motor, and also allows one to enjoy water leisure by having a simple configuration so as not to be burdened by the purchase cost. Background Technology

[0002] In general, various outdoor leisure sports are developing, and among them, water leisure sports that can be enjoyed in rivers, lakes, or the sea are particularly well-developed.

[0003] These water leisure sports are continuously evolving in a direction that seeks to realize thrills and self-satisfaction through challenges and adventures. Recently, non-motorized rubber boats capable of high-speed operation on the water by being towed by a motorboat, such as banana boats, flyfish, and bandwagons, have been gaining popularity. By having multiple people board and tow the boat at high speed, one can enjoy the thrill of high-speed operation on the water.

[0004] However, in the case of such conventional water leisure sports, multiple people board the vessel and tow it at high speed on the water using a motorboat, so it is difficult for a single user to use, and the cost of a single use is high, so the reality is that many people are reluctant to use it due to the financial burden.

[0005] Accordingly, various technologies are being devised to enable a single user to enjoy water leisure activities on the water.

[0006] For example, registered patent No. 10-0997493 describes a water leisure boat, which consists of a bow section containing a buoyancy member that generates buoyancy, a handle, a frame connected to the bow section, a fin, a third connecting shaft, and a vertical tail section at the rear of the frame containing the buoyancy member. This design does not require a separate motor such as an engine or a power transmission mechanism such as pedals and a chain in a water bicycle, and enables the water leisure boat to move by means of the propulsion force generated by the fin of the water leisure boat by shifting the user's center of gravity on the boat in the forward-backward or up-down direction through the water leisure boat's own buoyancy.

[0007] However, in the case of such conventional technology, since the user must repeatedly move the center of gravity to move the boat forward, the repeated movement on the boat floating on the water surface poses a risk of safety accidents in which the user falls into the water.

[0008] Moreover, as users must move forward while repeatedly shifting their center of gravity, it causes extreme fatigue during water play, which not only makes it impossible to enjoy water play, but also poses a problem in that women or adolescents with relatively less physical strength find it difficult to repeatedly perform upper body movements, making it impossible to properly enjoy water play.

[0009] As another example, a pedal-driven watercraft, disclosed in Utility Model Registration No. 20-0400112, has been devised. This comprises a power transmission unit formed by the longitudinal axis of a straight frame connecting the centers of a front fixed shaft and a rear fixed shaft located on the upper surface of each, a steering wheel located at the end of a steering wheel rotation axis perpendicular to the front fixed shaft and the longitudinal axis of the straight frame, a saddle connected to the end of a saddle fixed shaft located on the upper surface of the longitudinal axis of the straight frame and parallel to the steering wheel rotation axis, wheels connected to both ends of the rear fixed shaft, a main gear in which a pedal is installed on a rotation axis connected to the longitudinal axis of the straight frame and rotates by human power through the pedal movement, a driven gear in which a screw propeller is installed at the end of the longitudinal axis of the straight frame and rotates by receiving the rotational force of the main gear to rotate the screw propeller, and a chain connected to the main gear and the driven gear to transmit the rotational force of the main gear to the driven gear, and at the end of the longitudinal axis of the straight frame It consists of a rudder vertically connected in the downward direction and a buoyancy body that forms left-right symmetry around the longitudinal axis of a straight frame and connects both ends of the front fixed axis and the rear fixed axis.

[0010] Although this conventional technology allows for easy movement on land, reduces resistance from wheels on water to achieve maximum speed, creates shade during movement, and improves usability and convenience by being easy to assemble and disassemble, there is a problem in that the user must repeatedly alternately press the pedals to move the boat forward on the water surface, which causes pain in the user's leg muscles as well as back muscles. Additionally, women and adolescents, who have relatively less physical strength, find it difficult to repeatedly alternately pedal, which causes the inconvenience of not being able to enjoy water activities.

[0011] Moreover, because the components are complex, the purchase cost is burdensome, and the expectation for widespread adoption is inevitably lowered due to this economic burden.

[0012] Accordingly, there is an urgent need for the development of technology for a water boat that allows for enjoyable water play by being easy for anyone to use, while also maximizing the user's sense of stability when enjoying water play on the water surface so as not to burden the purchase cost through a simple configuration, and preventing safety accidents such as falling into the water.

[0026] In addition to the above objectives, other objectives and features of the present invention will become apparent through the description of embodiments with reference to the accompanying drawings.

[0027] Unless otherwise defined, all terms used herein, including technical or scientific terms, have the same meaning as generally understood by those skilled in the art to which the present invention pertains. Terms such as those defined in commonly used dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the relevant technology, and should not be interpreted in an ideal or overly formal sense unless explicitly defined in this application.

[0028] Hereinafter, a waterboard-type water leisure boat according to an embodiment of the present invention will be described in more detail with reference to the attached drawings.

[0029] As described above, the present invention comprises a body (10) formed in the shape of a waterboard, a handle (20) held by a user, a motor support (30) provided on the inner side of the body (10), a motor (40) supported on the motor support (40), a control unit (50), and a propulsion screw (60).

[0030] The above body (10) is formed in the shape of a waterboard as illustrated, and

[0031] A hollow buoyancy space (11) is provided inside, a buttock seating part (12) on which the user's buttocks are seated, a thigh contact part (13) on which the user's thighs are in contact with the buttock seating part (12), and a belly contact part (14) on which the user's belly is in contact while lying face down are provided, an arc-shaped support part (15) is provided on the front side, and a steering key (16) is provided protruding from the bottom surface.

[0032] The reason the above support member (15) is provided in an arc shape is to minimize water resistance when the body (10) moves forward on the water surface.

[0033] As such, since the body (10) is formed into a waterboard shape by means of a buttocks seating portion (12), a thigh contact portion (13), a belly contact portion (14), and an arc-shaped support portion (15), when the user places their buttocks on the buttocks contact portion (12) and presses their thighs against the thigh contact portion (13) and presses their belly against the belly contact portion (14), the user naturally assumes a prone position on the upper surface of the body (10) formed into a waterboard shape.

[0034] Accordingly, even if the body (10) moves forward, the shaking of the user can be minimized, thereby preventing the user lying face down on the body (10) from falling into the water and causing a safety accident.

[0035] The handle (20) is provided on the front side of the body (10) and is gripped by the user with both hands, and is equipped with a push switch (21).

[0036] In addition, when a user lies face down on the body (10) and grasps the handle (20) with both hands, the handle (20) is provided to protrude from each side of the body (10) so that the user grasps the handle (20) while lying face down with their belly pressed against the belly contact portion (14) of the body (10).

[0037] Additionally, in order to allow the user to lift their upper body while sitting on the upper surface of the body (10) or to grasp the handle (20) while standing on the upper surface of the body (10), the handle (20) is provided to protrude from the upper surface of the body (10).

[0038] The motor support (30) is provided on the rear side of the buoyancy space (11) of the body (10) and is provided with a motor mounting portion (31) on which a motor is mounted at the top, and is provided with a motor shaft connecting groove (32) that penetrates the rear of the body (10).

[0039] The motor (40) is formed by connecting one side of a rotating shaft (42) that is mounted on the motor mounting portion (31) of the motor support (30), electrically connected to the power supply portion (41), and exposed to the rear outer side of the body (10) by penetrating the motor shaft connection groove (32).

[0040] The control unit (50) electrically connects the push switch (21) provided on the handle (20) to the motor (40) and supplies power from the power supply unit (41) to the motor (40) by pressing the push switch (21) to drive the motor (40) and rotate the propulsion screw (60). The propulsion screw (60) is connected to the other side of a rotating shaft (42) that is connected to one side of the motor (40) and rotates in the same manner as the rotating shaft (42) by the rotational power of the motor (40).

[0041] The present invention, formed in this manner, allows a user to lift their upper body while lying face down on the upper surface of the body (10) which is shaped like a waterboard, or while sitting on the upper surface of the body (10), or while standing on the upper surface of the body (10), and then grasp the handle (20) with both hands, and then press the push switch (21) provided on the handle (20) to cause the body (10) which is shaped like a waterboard to move forward.

[0042] That is, when the push switch (21) is pressed toward the handle (20) while holding the handle (20), the control unit (50) electrically connected to the push switch (21) detects this and supplies power to the motor (40) electrically connected to the power supply unit (41), and the motor (40) supplied with power is driven, and the rotational power generated by the driving of the motor (40) is transmitted to the rotation shaft (42), and the propulsion screw (61) connected to the other side of the rotation shaft (42) rotates, thereby generating propulsion force and moving forward on the water surface of the body (10) which is formed in the shape of a water board.

[0043] The present invention is provided with a screw protector (70) that covers and protects the propulsion screw (60). As illustrated, the screw protector (70) comprises a first protective mesh body (72) in which the propulsion screw (60), which is connected to the other side of the rotation shaft (42), is located inside; a rotation shaft connecting part (73) that protrudes from the top of the first protective mesh body (72), through which the rotation shaft (42), which is connected to the other side of the propulsion screw (60), is fitted and fixed in the motor shaft connecting groove (32); and a second protective mesh body (74) that is detachably coupled to the bottom of the first protective mesh body (72).

[0044] In this way, since the circumference of the propulsion screw (60) is covered and protected by the first protective net (72) of the screw protection device (70), it is possible to prevent the propulsion screw (60) from breaking or being damaged by hitting foreign substances remaining in the water or stones while the propulsion screw (60) is rotating and the waterboard-type body (10) is moving forward, as well as to block foreign substances from entering and winding up the circumference of the propulsion screw (60).

[0045] In addition, the lower side of the propulsion screw (60) can be protected by the second protective mesh (74) of the screw protection device (70), thereby preventing damage and malfunction of the propulsion screw (60) caused by foreign substances in the water flowing into the lower side of the propulsion screw (60) and getting tangled.

[0046] As illustrated in FIG. 5, the present invention further comprises an elastic fastening projection (75) protruding from the lower circumferential surface of the first protective net body (72), and the second protective net body (74) of the screw protector (70) further comprises an arc-shaped elastic detachable part (76) that opens when pushed toward the lower side of the first protective net body (72) and then opens when fitted into the lower end of the first protective net body (72) and adheres to the lower circumferential surface of the first protective net body (72), and an elastic fastening groove (77) that is fastened to the elastic fastening projection (75) when the arc-shaped elastic detachable part (76) adheres to the lower circumferential surface of the first protective net body (72).

[0047] Since the present invention, constructed in this manner, allows the second protective net (74) to be detached from the bottom of the first protective net (72), for example, when the propulsion screw (60) installed and positioned on the first protective net (72) malfunctions or fine foreign matter gets wrapped around the propulsion screw (60), the arc-shaped elastic detachable part (76) is spread outward to separate the elastic fastening projection (75) from the elastic fastening groove (77), thereby separating the second protective net (74) from the bottom of the first protective net (72) and proceeding with the replacement or repair of the propulsion screw (60).

[0048] Of course, after the replacement or repair work of the propulsion screw (60) is completed, the second protective net (74) that was separated again is positioned at the bottom of the first protective net (72), and the second protective net (74) is pushed toward the first protective net (72) to combine them.

[0049] Accordingly, the repair and maintenance workability of the propulsion screw (60) can be greatly improved, and if the second protective net (74) is damaged, the work of replacing the damaged second protective net (74) with a new one can be easily performed.

[0050] The handle (20) equipped with the push switch (21) of the present invention can be implemented in various modified ways so that the user can grasp it while lying face down on the upper surface of the body (10), or while sitting on the body (10), or while standing on the upper surface of the body (10).

[0051] That is, as illustrated in FIG. 1, it may be composed of a first handle (22) that protrudes from one side of the body (10) and has the push switch (21), and a second handle (23) that protrudes from the other side of the body (10).

[0052] At this time, the first handle (22) and the second handle (23) may be connected by fitting to one side and the other side of the body (10), respectively, or may be formed integrally with the body (10).

[0053] As such, since a first handle (22) having a push switch (21) is provided on one side of the body (10) and a second handle (23) is provided on the other side of the body (10), after the user’s buttocks are placed on the buttocks seating portion (12), the user lies face down on the upper surface of the body (10) with the belly in contact with the belly contact portion (14) and the thighs in contact with the thigh contact portion (12), then the user grasps the first handle (22) and the second handle (23) forming the handle (20) with both hands, and presses the push switch (21) provided on the first handle (22) to move the body (10), which is shaped like a waterboard, forward to enjoy water leisure.

[0054] At this time, when the user holds the handle (20) and presses the push switch (21) provided on the first handle (22) toward the first handle (22), the waterboard-type body (10) in which the user is lying face down moves forward, so as operability and convenience can be greatly improved, so even women or teenagers with little physical strength can easily and simply enjoy water play, that is, water leisure.

[0055] In addition, since the forward movement of the body (10), which is shaped like a water board, is carried out while the user is lying face down, the shaking of the user can be minimized while the body (10) moves forward on the water surface, thereby preventing water safety accidents in which the user falls into the water.

[0056] When the first handle (22) and the second handle (23) forming the handle (20) are respectively provided on one side and the other side of the body (10), the user can control the body (10) moving forward in the left or right direction by twisting the upper body while holding the handle (20) composed of the first handle (22) and the second handle (23) provided on one side and the other side of the body (10) with both hands, and the directional key (16) protruding from the lower surface of the body (10) twists in the same direction as the upper body being twisted. When the pressing operation of the pressed push switch (21) is released, the rotational operation of the propulsion screw (60) stops, and accordingly, the forward movement of the body (10) stops.

[0057] Additionally, as illustrated in FIGS. 6 to 8, the upper end of the steering key (16) is provided with a steering shaft fitting part (18) having a first fixing hole (17), and the body (10) is provided with a steering support hole (19) that penetrates so as to communicate with the front upper surface and the lower surface of the body (10), and a steering key support member (93) having a second fixing hole (92) at the top and a support flange (91) protruding from the top that is fitted into the steering support hole (19) and supported by being seated on the upper surface of the body (10), and a bearing (94) that is fitted into the inner side of the steering key support member (93) and has its outer surface bolted to the second fixing hole (92), and a member that is fitted through the steering support hole (19) and positioned inside the bearing (94), and is provided at the bottom of the steering shaft fitting part (18) of the steering key (16). A steering key support rod (90) is further provided, through which a second fixing hole (95) that is bolted to the first fixing hole (17) is penetrated at the bottom.

[0058] At this time, the handle (20) is composed of a handle fixing part (24) bolted to the upper end of the steering key support rod (90) so that the user of the present invention can grasp it while sitting on the upper surface of the body (10) or standing on the upper surface of the body (10), a third handle (25) having the push switch (21) and extending in one direction of the upper end of the handle fixing part (24), and a fourth handle (26) extending in the other direction of the upper end of the handle fixing part (24).

[0059] The present invention, thus formed, allows the user to sit on the upper surface of the body (10) by lifting the upper body after placing the user's buttocks on the buttocks seating portion (12), or to hold the handle (20) while standing on the upper surface of the body (10), and to steer the forward direction of the body (10) by rotating the steering key (16) protruding from the lower surface of the body (10).

[0060] That is, when the user rotates both hands to the left or right while gripping the third handle (25) and the fourth handle (26) with both hands, the handle fixing part (24) extended to the upper side and the other side of the third handle (25) and the fourth handle (26), respectively, rotates, and the steering key support rod (90) rotates as the handle fixing part (24) rotates, and the steering shaft fitting part (18), to which the lower end of the steering key support rod (90) is bolted, rotates as the steering key (16) rotates in the same direction as the user's hands rotate, thereby steering the body (10).

[0061] At this time, the steering key support rod (90) is fitted into the inner side of the bearing (94) which is bolted to the steering key support member (94) fitted into the steering support hole (19), so that the rotational movement of the steering key support rod (90) is not interfered with at all.

[0062] In addition, since the steering key support (93) is fitted into the steering support hole (19) and is fixed by the support flange (19) so as not to fall out toward the lower side of the steering support hole (19) penetrating the body (10), and the steering key support (93) and the bearing (94) are bolted together and the steering key support rod (90) is fitted into the bearing (94), it is easy for a user to grasp and rotate the handle (20), which consists of the third handle (25) and the fourth handle (26), with both hands while sitting or standing on the upper surface of the body (10).

[0063] It is obvious that, as needed, the steering key support rod (90) can be provided with two pieces that can be inserted and removed from each other, allowing the height of the steering key support rod (90) to be used differently.

[0064] The present invention, as described above, allows a user to enjoy water leisure activities by sitting on the upper surface of the body (10) without lying face down on the upper surface of the body (10), lifting the upper body, and then moving the body (10) forward while holding the third handle (25) and the fourth handle (26) forming the handle (20) with both hands while the upper body is lifted.

[0065] In addition, since the user can hold and support the third handle (25) and the fourth handle (26) forming the handle (20) with both hands while standing up from the upper surface of the body (10) without sitting on the upper surface of the body (10), the user can obtain an experience similar to riding a jet ski and can enjoy water leisure activities by moving the body (10) forward while assuming various postures.

[0066] As shown in FIG. 9, the present invention may further be provided with a cover (80) for replacing or repairing a motor (40) and a power supply unit (41) that are supported on a motor support (30) provided on the rear side of the buoyancy space (11) of the waterboard-type body (10).

[0067] At this time, the cover (80) is hinge-connected to the waterboard-type body (10) on one side, and after opening the cover (80) hinge-connected to the body (10) on one side to open the buoyancy space (11) of the waterboard-type body (10), the motor (40) or power supply unit (41) that is seated and supported on the motor support (30) can be replaced or repaired.

[0068] As described above, the present invention has been explained by specific details such as specific components, limited embodiments, and drawings; however, this is provided merely to aid in a more comprehensive understanding of the invention, and the invention is not limited to the above embodiments. A person skilled in the art to which the invention pertains can make various modifications and variations from this description.
