Description

[Technical field]

[0001] The present invention relates to a device for preventing rolling of a boat, particularly a small boat, caused by waves or the like. [Background technology]

[0002] In a conventional technique, a penetrating tube is pulled up from the water onto the ship for navigation, and the rope suspending the tube is temporarily pulled up in a U-shape together with a pulley from a pole to the deck or bottom of the ship, and in an emergency, the pulley is released by removing it from the deck or bottom of the ship using a pulley release mechanism provided on the pulley, creating slack in one go, so that the tube of the anti-rolling device can be quickly lowered into the water even when encountering large waves, preventing capsizing (see Patent Document 1).

[0003] Also, as a conventional prior art, there is a ship anti-rolling device in which one end of an anti-rolling plate is attached to each of anti-rolling plate support members provided on both sides of the hull so that the entire anti-rolling plate can rotate up and down or the other end of the anti-rolling plate can elastically deform up and down, and the anti-rolling plate support members and the anti-rolling plate can be switched between a stored state in which the entire anti-rolling plate is located inside the hull or above the water surface, and an operating state in which the anti-rolling plate is located underwater (see Patent Document 2).

[0004] [Patent Document 1] JP 2011-162150 A [Patent Document 2] Publication No. 7-22395 Summary of the Invention [Problem to be solved by the invention]

[0005] The former method is intended to deal with large ships and huge waves, and is not intended to reduce rocking in small waves for small ships like the present invention.

[0006] Moreover, the latter method is difficult to install on small boats that are generally available on the market, and would be a hindrance, so that it cannot be used as a chair as in the present invention.

[0007] The present invention seeks to solve the problems associated with such conventional configurations, and aims to provide a ship anti-rolling device which has a simple structure consisting of a frame, fixings, anti-rolling plates, etc., yet can be attached and detached freely to any type of small boat, and can also be used for chairs, etc. [Means for solving the problem]

[0008] In order to achieve the above-mentioned object, the present invention is a device that is installed at an appropriate location around the upper end of the ship's body, and comprises a preventive device main body with fixing devices provided on both sides of a frame to be installed at the upper end, and a support part provided on at least one side of the preventive device main body for vertically supporting a slidable anti-rolling plate that is installed on the upper surface of the frame. An engaging part is provided at one end of the anti-rolling plate. The frame is provided with an engaging piece for engaging the anti-rolling plate, and the support part is provided with a support piece at the top and guide pieces on both sides. The support part is provided with a fixed piece for engaging and fixing the anti-rolling plate. A sliding part is provided to enable the frame to slide left and right. The device is characterized in that a lateral roll prevention part is provided at the lower part of the anti-rolling plate. Effect of the Invention

[0009] 1) Although it has a simple structure consisting of a frame, fixings, anti-roll plates, and supports, it can be installed in appropriate locations around the upper end of the body of a small ship and attached freely, thereby reducing roll against transverse waves, etc. 2) It can also be used as a chair. 3) The anti-roll plate can easily reduce lateral waves by sliding it sideways and supporting it vertically. 4) The support part ensures that the anti-sway plate is supported vertically. 5) The fixed piece allows the anti-sway plate to be supported vertically more reliably. 6) By providing a sliding section so that the platform can be slid left and right, it can be adjusted to fit the width of the ship's body. 7) The anti-rolling section further prevents rollover and maintains stability.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] No. 1 is a ship anti-rolling device that is installed and attached in an appropriate location around the upper end of a small ship's body. Reference numeral 2 denotes the main body of the preventive device, which is provided with fasteners 2b, 2b on both sides of a flat frame plate 2a so that it can be detachably attached around the upper end of the ship's main body by means of bolts B. In addition, if necessary, locking pieces 2c, 2c are provided to prevent the anti-rolling plate, which will be described later, from slipping. Reference numeral 3 denotes an anti-sway plate provided on the upper surface of the frame plate 2a that can slide left and right and has an upwardly protruding locking portion 3a at its left end. Reference numeral 4 denotes a support portion that vertically supports the anti-sway plate 3, which is provided on one side of the preventive device body 2 and is formed in a U-shape at the front, with a support piece 4a at the top and guide pieces 4b (four in this embodiment) on both sides (Figs. 1, 2, and 3).

[0012] An example of the use of the above-mentioned anti-rolling device for a ship 1 will now be described. In order to install the boat anti-rolling device 1 around the upper end periphery S of the rear of the main body FH of a small boat F (basically intended for a fishing boat for 2 to 3 people or a small yacht), first, the fixing devices 2b on both sides are inserted from above the upper end periphery S and fixed in place by tightening the bolts B. Then, when one arrives at a fishing ground or the like, for example before going out fishing, one grasps the locking portion 3a of the anti-sway plate 3 and slides it sideways until it reaches the support portion 4, and then locks and fixes the locking portion 3a to the support piece 4a and guide piece 4b of the support portion 4 in order to support the frame 3 vertically.

[0013] In this state, the transverse wave N hits the anti-rolling plate 3, and the rolling of the small boat F can be reduced (Figure 4).

[0014] Next, the support portion 24 of the anti-rolling device for a vessel according to the second embodiment will be described. This support part 24 has the same shape as the support part 4, and has a cylindrical hook piece 4c on one side of the upper guide piece 4b, and a somewhat elastic hook wire 4d on the opposite guide piece 4b (FIGS. 5 and 6). This support portion 24 can reliably support and fix the anti-sway plate 3 by hooking the tip of the hook wire 4d onto the hook piece 4c. If necessary, they may be provided above and below.

[0015] Next, the mounting plate 32 of the anti-rolling device for a vessel according to the third embodiment will be described. The plate 32 is provided with a slide portion 5 having an insertion hole so that the plate 32 can slide left and right. This can be adjusted to fit the width of a small boat (Figure 7).

[0016] Finally, the anti-rolling plate 43 of the vessel roll prevention device of the fourth embodiment will be described. The anti-sway plate 43 is provided at its lower part with a wide (rectangular in this embodiment) anti-sway portion 43a. This makes it possible to further prevent rolling. (Fig. 8)

[0017] In each of the above embodiments, the material of each member is not particularly limited, and the size and shape are also not particularly limited as long as they have similar functions. Also, [Explanation of symbols]
