Abstract

PURPOSE:To enable tourists to see an underwater sight safely by arranging a watertight cabin for free sliding along a guide rail laid in an upright direction along the outer shell of hull construction. CONSTITUTION:A movable cabin 2 is supported by a davit 6 at a stowing position 2a on an upper deck and tourists embark the movable cabin 2 so supported. After the movable cabin 2 is totally closed, another davit 5 is made to fall and a hanging rope 6 is loosened. Then, the rollers 8 and 9 of the movable cabin 2 are introduced into the upper end opening of a guide rail 7. The movable cabin 2 goes down along the guide rail 7 via the rollers 7 and 8, and stops at a lowering position 2b. In this state, tourists therein can appreciate an outside sight through a peep hole.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an underwater sightseeing boat.

[Conventional technology]

Conventionally, the structure of a pleasure boat that allows underwater sightseeing has been
Various types have been proposed, but each has the following problems.

(1) Submersible vessels equipped with viewing windows on their hulls and sailing while sightseeing underwater require a steering system, navigation equipment, etc. for underwater navigation, and are difficult to take off and dock.

(2) It is difficult to control the depth of an underwater sightseeing cabin that is towed by a watercraft via a shear.

(3) Pleasure boats equipped with peepholes on the bottom of the ship for sightseeing on the ocean floor can only see downward, and tourists cannot experience the feeling of walking on the ocean floor themselves.

(4) Sightseeing cabins run along rails laid on the ocean floor, so the course is always the same, so there is little change in visibility.

[Problem that the invention seeks to solve]

The present invention has been proposed in view of these circumstances, and allows tourists to sightsee on the water until they reach a place suitable for underwater sightseeing where it is easy to approach and leave the shore. To provide an underwater sightseeing pleasure boat with a simple structure that allows you to sightsee safely as if you were walking underwater.

[Means for solving problems]

To this end, the present invention provides a pair of front and rear parallel guide rails installed vertically along the side outer plate of the hull, and a roller that has negative buoyancy and rolls along the parallel guide rails that protrudes from the side. Once installed, there will be a watertight movable cabin equipped with a plurality of viewing windows, and a movable watertight cabin that will be erected on the upper deck of the ship and suspended via a hanging cable. It is characterized by comprising a davit that is moved up and down along the parallel guide rail.

[For production]

With this configuration, it is easy to approach and leave the shore, and it is possible to sightsee on the water until you reach a place suitable for underwater sightseeing, and at the underwater sightseeing point, tourists can safely follow the desired course as if they were walking underwater themselves. You can get a simple underwater sightseeing boat for sightseeing.

[Embodiment] An embodiment of the present invention will be explained with reference to the drawings. Fig. 1 is a side view thereof, Fig. 2 is a cross-sectional view taken along the line ■-■ in Fig. 1, and Fig. 3 is a cross-sectional view taken along the line ■-■ in Fig. Figure 4 is a cross-sectional view taken along ■-■ in Figure 2. Figure 5 is a cross-sectional view taken along ■-■ in Figure 4.
FIG.

In the above diagram, 1 is the hull, and 2 is a plurality of movable cabins that can be raised and lowered, which are stored on the side deck of the hull 1 and can accommodate tourists as needed and dive underwater along the outer shell. Peepholes are installed above, below, and around 9 sides.

Reference numeral 3 denotes a pair of front and rear protruding arms that protrude from the sides of the movable cabin 2, and a roller 4 that rolls along a guide rail 7, which will be described later, is pivotally supported at the tip of the arm.

5 is a davit which is protruded from the side deck of the hull so that it can be raised and lowered freely, and suspends the movable cabin 2 via a suspension rope 6; The guide rails are a pair of front and rear guide rails having a C-shaped cross section, and the upper ends thereof are provided with a tapered portion 7a17b that widens upward.

Reference numerals 8 and 9 denote rollers pivotally attached to T-shaped metal fittings 10 protruding from the tips of the protruding arms 3. The rollers roll along the grooves of the guide rail 7, and the two rollers cooperate to form the roller 4.

In such a structure, as shown in Figures 1 and 2, the movable cabin 2 is supported by a davit 5 at a storage position 2a on the upper deck, and in this state tourists board the movable cabin, and when boarding is completed. If so, seal the movable cabin.

Next, as shown by the broken line, the davit 5 is brought down to the unstretched position, and then the suspension rope 6 is gradually loosened. are introduced into the upper end opening guided by the tapered portions 7a and 7b, respectively, and then stably lowered along the υ guide rail by rollers 8 and 9, and the rollers 8 and 9 It comes into contact with a stopper (not shown) and stops at the lowered position 2b.

Tourists inside the movable cabin can view the outside through the viewing window.

During this time, the ship can either stop or move freely.

When the underwater sightseeing is finished, the suspension cable 6 is hoisted up by a deck winch (not shown), and the movable cabin rises along the guide rail, emerges upward from the upper end of the guide rail, and then attaches to the tip of the davit. Upon contact, the davit rotates from the swinging out position to the retracted position and returns to its initial position, allowing the occupant to disembark from the cabin.

In the meantime, when the movable cabin is raised or lowered, its guide rollers are guided along the guide rails, so the raising and lowering is carried out safely and stably.

According to such a pleasure boat, the following effects can be achieved.

(1) Pleasure boats have the function of underwater sightseeing, but they are usually easy to take off and dock from, just like watercraft. (2) Sightseeing on the water is not possible until you reach a place suitable for underwater sightseeing. can.

(3) The movable cabin allows tourists to explore the water as if they were walking underwater.

(4) The underwater sightseeing course can be changed as appropriate.

(5) The structure is simple as there is no particular need for a propulsion device, a control device, etc. for underwater navigation.0 (6) Safe navigation in water is possible.0 [Effects of the Invention] In short, the present invention For example, if a pair of front and rear parallel guide rails are installed vertically along the outer side of the ship's hull, and a roller that has negative buoyancy and rolls along the parallel guide rails is provided protruding from the side. A watertight movable cabin is provided with a plurality of observation windows, and the watertight movable cabin is suspended via a hanging rope that is erected on the upper deck of the hull and is suspended along the parallel guide rail. By equipping it with a davit that can be raised and lowered by the pier, it is easy to approach and leave the shore, and it is possible to sightsee on the water until reaching a place suitable for underwater sightseeing.At the underwater sightseeing point, tourists can walk underwater along the desired course The present invention is industrially extremely useful because it provides an underwater sightseeing boat with a simple structure that allows you to safely sightsee in the mood of sightseeing.
