Abstract
Description
Yacht hull improvement structure Technical Field
[0001] This work relates to the structural design of a yacht hull; in particular, it refers to a technology for a combined structure that strengthens the hull frame and pontoons. Prior Technology
[0002] The application of pontoon structures on both sides of watercraft (e.g., ships, yachts or similar vehicles) to increase buoyancy and stability is a well-known art; for example, patents such as CN 111439346 A "Pontoon Yacht for Fishing" and CN 215826948 U "Floating Structure and Boat" provide typical embodiments.
[0003] These types of watercraft typically have a structure in which pontoons are installed in the area around the hull (or on both sides) in a direction parallel to the hull axis. The pontoons have internal spaces (or chambers) to contain air, foam, or similar materials, in order to achieve the aforementioned effects of improving the hull's buoyancy and stability.
[0004] As those skilled in this art know, the following issues remain unresolved or unaddressed:
[0005] 1. It is known that pontoon structures usually only serve to provide buoyancy to the hull, and lack the function of blocking and / or guiding the impact of waves on the hull, thereby improving the stability of the hull.
[0006] 2. The conventional hull-float combination structure cannot withstand the impact of waves during long-term or high-frequency use; therefore, the combination structure of the hull and the floats is prone to loosening and separation, resulting in an unstable connection, which is not what we want.
[0007] Representatively, these references illustrate the usage and structural design of conventional hulls, pontoons, or their related components. Redesigning the hull and pontoon structures, and considering the aforementioned applications, to differ from conventional practices, could alter their usage, expand their scope of application and / or effectiveness, thus differing from the old methods.
[0008] For example, considering the need to improve the buoyancy of the hull, a combined structure of the hull and pontoons could be provided to block and / or guide the direction of wave motion, thereby reducing the impact of waves on the hull and improving the stability of the hull. Alternatively, the pontoon structure could be further considered to strengthen the stable combination of the pontoons and the hull (and / or frame) or to make them support each other, reducing the likelihood of loosening or separation during long-term or high-frequency use. These issues are not taught or specifically disclosed in the aforementioned references. Summary of the Invention
[0009] Therefore, the main purpose of this invention is to provide an improved hull structure for yachts, which reduces wave impact on the hull deck and strengthens the connection between the pontoons and the hull. The hull includes a combination of a frame and pontoons, with the pontoons located on both sides of the hull and integrated with the frame. The pontoons (upper area) have outward-protruding shoulders and inward-protruding secondary shoulders; the shoulders help to block wave impact on the hull, making the secondary shoulders more firmly integrated with the hull, thus improving the situation where conventional (assembled) structures are prone to loosening and separation.
[0010] Based on the improved yacht hull structure of this invention, the side areas of the pontoons are formed with a sloping structure; corresponding to the sloping structure, the side areas of the frame are also formed with sloping structures, so that the pontoons, after being attached to the frame, form a mutually abutting shape. Furthermore, during the hull's operation, the force generated by the waves impacting the pontoons helps to create mutual support between the sloping structures of the pontoons and the sloping structures of the frame, resulting in a more stable combination of pontoons and frame.
[0011] Based on the modified yacht hull structure of this creation, the hull is equipped with a protective structure; the protective structure extends (protruding) from the front area of the hull towards the side areas and upwards. Furthermore, the protective structure gradually slopes upwards from the front area of the hull towards the side areas to guide the movement path of waves and reduce or mitigate the direct impact of waves on the cockpit glass area.

[0018] Please refer to Figures 1, 2 and 3. The modified hull structure of the yacht created in this invention is generally referred to as reference number 100; the hull 100 includes a combination of frame 10 and pontoons 20.
[0019] In the following descriptions, the terms front (or front end), back (or rear end), front part, back part, top (or upper part), bottom (or lower part, bottom), side, etc., refer to the direction shown in the figure.
[0020] The diagram shows that a radar and collision avoidance ball placement device 90 can be installed on the top area of the hull 100 to establish a navigation function. The hull 100 is also equipped with a protective structure 80; the protective structure 80 extends from the forward region of the hull 100 towards the side regions and upwards (protruding). The protective structure 80 gradually slopes upwards from the forward region of the hull 100 towards the side regions (or from the bow to the hull side) to guide the movement path of waves (or wave breaking, wave dissipation), reduce wave impact on the bow deck 85, and / or mitigate the direct impact of waves on the bridge glass area 88.
[0021] It is understood that the installation of the guardrail structure 80 can also relatively increase the height or position of the bow deck 85, and work together with the guardrail structure 80 to form a wave-breaking front barrier; in addition, it can also reduce the possibility of the large bridge glass area 88 being damaged by the impact of sea waves.
[0022] In the adopted embodiment, the upper region of the float 20 (in conjunction with the welding operation) is provided with a storage space 70 (or storage box) for personnel to store items; therefore, the protective structure 80 can be optionally set in the upper region of the float 20 and / or the upper region of the storage space 70.
[0023] The figure also depicts pontoons 20 positioned on both sides of the hull 100 (or frame 10), integrated with the frame 10. The frame 10 has a keel 11 and multiple supports 12 connecting the keel 11; the supports 12 extend from the keel 11 toward the side areas of the hull 100, collectively defining the outline of the hull 100. Furthermore, the sides of the supports 12 (at least partially) have beveled structures 13.
[0024] Please refer to Figures 3, 4 and 5. The float 20 is defined or has an outer wall 28 facing outward (or located in the outer region), an inner wall 29 facing inward (or located in the inner region) and a bottom wall 24 located in the bottom region of the float 20.
[0025] In the adopted embodiment, the pontoon 20 (upper region) has a shoulder 21 protruding outward and a secondary shoulder 22 protruding inward; the shoulder 21 can help to block the impact of waves on the hull 100. Furthermore, the combination of the secondary shoulder 22 and the hull 100 can strengthen the stable connection between the pontoon 20 and the hull 100, and improve the situation where conventional (assembled) structures are prone to loosening and separation.
[0026] The figure also depicts that the inner wall 29 of the pontoon 20 (or the direction towards the hull 100) has a sloping structure 23; corresponding to the aforementioned sloping structure 13, after the pontoon 20 is joined to the frame 10, the sloping structure 23 and the sloping structure 13 form a mutually abutting shape; in conjunction with the welding operation, the pontoon 20 and the frame 10 form a more stable joint.
[0027] In the adopted embodiment, a groove structure 25 is provided between the bottom region (or bottom wall 24) and the outer wall 28 of the float 20. Furthermore, the bottom wall 24 of the float 20 is of a type that gradually slopes upward from the outside (or outer wall 28) towards the inside (or inner wall 29).
[0028] Please refer to Figure 5. A concave portion 30 is formed between the bottom wall 24 of the pontoon 20 and the bottom plate 14 of the hull 100.
[0029] Specifically, the bottom plate 14 of the hull 100 (in conjunction with welding operations) connects the support 12 and the pontoon 20 (or the inner wall 29 of the pontoon 20); the bottom plate 14 forms a gradually inclined upward structure from the keel 11 of the frame 10 outward (or towards the pontoon 20), and together with the bottom wall 24 structure of the pontoon 20, it forms the aforementioned concave part 30.
[0030] It is understood that the groove structure 25 and concave part 30 of the float 20 help to guide the movement path of the waves and also increase the stability of the hull 100.
[0031] The imaginary lines in Figure 5 depict the role of the shoulder 21 in assisting to block the impact of waves on the hull 100. Furthermore, during the movement of the hull 100, the component force generated by the waves impacting the pontoon 20 helps to create mutual support between the inclined surface structure 23 of the pontoon 20 and the inclined side structure 13 of the frame 10, resulting in a more stable combination between the pontoon 20 and the frame 10.
[0032] Please refer to Figure 6, which illustrates a modified embodiment; the internal space of the pontoon 20 can accommodate air, foam filler 40 or the like, to achieve the aforementioned effects of improving the buoyancy and stability of the hull 100.
[0033] Representatively speaking, this modified yacht hull structure, while meeting the requirement of increasing the hull's buoyancy by 100%, has the following considerations and advantages compared to the old method:
[0034] 1. The hull 100 and related mating structures have been redesigned and reconsidered. For example, the support 12 of the frame 10 is provided with a beveled structure 13; the pontoon 20 is provided with a shoulder 21 and a secondary shoulder 22, the inner side wall 29 of the pontoon 20 forms a beveled structure 23, corresponding to the beveled structure 13 of the support 12; a groove structure 25 is formed between the outer side wall 28 and the bottom wall 24 of the pontoon 20, etc. These structural parts are significantly different from those of conventional users and have changed its use and operation mode, thus differing from the old method.
[0035] 2. In particular, the frame 10, pontoons 20 and related structures of the hull 100 not only have the function of blocking and / or guiding the direction of wave movement to reduce the impact of sea waves on the hull 100, but also improve the stability of the hull 100 during operation; and further strengthen the stable combination of the pontoons 20 and the frame 10 and / or make them support each other, reducing the possibility of loosening or separation due to sea wave impact during long-term / long-term or high-frequency use.
[0036] Therefore, this invention provides an effective improved structure for yacht hulls, whose spatial form is different from that of conventional methods and has advantages that cannot be matched by old methods. It demonstrates considerable progress and fully meets the requirements of a new patent.
[0037] However, the above description is merely a feasible embodiment of this invention and is not intended to limit the scope of implementation of this invention. All equivalent changes and modifications made in accordance with the scope of the patent application of this invention are covered by the scope of the patent application of this invention.
