Description

  The present invention relates to a stern jet ski mount that can mount and moor a jet ski at the stern of a leisure boat or the like.

At sea, jet skiing (water skiing, water bikes, etc., hereinafter collectively referred to as “jet skiing”) is performed. In this case, there is no problem if you enjoy the beach or near the shore, but if you want to enjoy offshore, conventionally, tow off to the offshore with a larger leisure boat, etc. You will enjoy skiing. However, when towing a jet ski, even if it is large, the speed of the leisure boat may be slowed down, and the towing may be cut off halfway or the towing jet ski may be overturned.
Therefore, it can be considered to be mounted on the stern of a leisure boat or the like until offshore to enjoy jet skiing.

As an example in which this kind of platform (base) is provided at the stern of the hull, for example, the one disclosed in Japanese Utility Model Publication No. 138728 (Japanese Utility Model Publication No. 62-138728) is known.
The disclosure of Japanese Utility Model Publication No. 62-138728 is related to the devised name “floor work table”. “Every time it moves, the support frame 107a needs to be tilted. When towing and moving the work table” Since the support frame 107a is raised and secured to the stern surface 110a, each time it moves, it is necessary to tie up, tilt, and unlock. In order to solve the problem of causing fatigue and damage of the part because all stress concentrates on the joint part of the support frame 107a and the hull 101. For the purpose of “providing a floating work table having a simple, lightweight and inexpensive structure that can improve work efficiency and sufficiently prevent the conductor pipe from swinging” (page 3, page 2). Line to page 4, line 14), " The mounted cantilever type floating work platform has a structure in which a concave portion is provided on the stern surface of the hull, a support frame is disposed almost inside the concave portion, and a conductor pipe for excavation is supported by the support frame. (Refer to the description in the scope of claim for new model registration) By adopting such a structure, “the strength of the floating worktable that can sufficiently prevent the conductor pipe from swinging is simple, lightweight and inexpensive. It can be manufactured, and the work efficiency can be improved because the work of raising and lowering the support frame is not required (see the same publication, page 6, line 20 to page 7, line 5). .

5 and 6 are a plan view and a partial perspective view of an embodiment of a floating work platform disclosed in the publication. In FIGS. 5 and 6, reference numeral 101 denotes a hull, 105 denotes a conductor pipe, 107a, 107b is a support rack, 110a and 110b are stern surfaces, and 112 is a recess (in addition, in order to clarify that the reference is prior art, the applicant of the present application has changed to three digits to explain. did.).
However, the floating workbench shown in FIGS. 5 and 6 is a “cantilever-type floating workbench equipped with excavation equipment”, that is, a large-scale construction workbench that is easy for leisure such as jet skiing. It is not a facility, and after having enjoyed jet skiing offshore with a ship equipped with this work table, it is necessary to mount and moor the offshore jet ski, which requires separate equipment such as an onboard crane. There are problems such as.
