Underwater observation boat

The invention relates to an underwater observation boat with a downwardly transparent surface.

It is known to have the floor in front of benches in Äusflugsbooten transparent so that the fauna and flora of the underwater world can be observed. This possibility of observation but has not become very popular because, on the one hand, the transparent surfaces are made of relatively solid and thick material, on the other hand, reflections from sunlight can occur and continue to occur the viewing angle also has an unfavorable effect under these circumstances.

However, there is considerable interest in underwater observations. For example, there are swimmers who wear a diving mask with a snorkel for the sole purpose of doing this procure, watch the bottom while swimming on the surface to be able to.

909837/0032

On the one hand, this possibility is often older people, especially powerful swimmers, closed and on the other hand consists Interested in the underwater observation experience not only to open up to this group of people, but also to keep the underwater observers more interesting to make sure that time constraints to which a swimmer is subjected should be avoided. Included must also be taken into account that an observation by a swimmer is often problematic, as this is caused by the swimming movements. frightens many animals and causes them to retreat into hiding places so that they evade observation "

With an observation boat these disadvantages are avoided according to the invention or these possibilities are reserved, that the boat has at least one shaft that is open at the bottom and at the top and that leads upwards over the waterline with a suspension device for a show use has, the channel-shaped running open at the top and closed at the lower end by a transparent disc is.

These are advantageously small, rentable Boats which, because the shaft is provided, allow glare-free observation of the bottom. Above all allows a boat to approach you carefully

909837/0032

Observation place or lingering motionless over such a place, so that shy (eggs can be. The removable arrangement of the -. sentence allows - apart from the fact that it is largely protected in the shaft anyway - that one if necessary Fragile lens only at the point of observation is used. However, the invention is not limited to the use of a pane of glass, but also sees the arrangement of another transparent material, for example clear plastic, before.

The suspension device is advantageous as it is known per se cardanic suspension, which enables angle adjustment in any direction. This leaves the area of observation extends far beyond the section that lies below the boat. Above all it is thus possible to follow processes on the ground that are moving ..

According to an advantageous embodiment, there is at least a part of the suspension device from two half-shells which are rotatably arranged in the side walls of the shaft and ax penetration of bearing journals of the display insert and its fixing after twisting the half-shells to the Ensure the top of the cones due to the buoyancy. This also becomes part of the cardanic suspension

909837/0032

created and pivoting about the axis of the half-shells enables

A "particularly advantageous feature is the execution of the shaft with one to its exits, namely at least a downward widening cross-section, which allows a wide, radially symmetrical deflection of the display insert.

The invention extends not only to boats made of solid material such as wood, plastic and the like, but looks like the execution of the boat made of inflatable material before that the shaft from an inflatable wall part beet ent, on which the hanging device for the show use is arranged. As a result, the shaft can optionally only be created at the observation site, so that he "does not interfere with the other use of the boat. Especially with the latter version, the boat has one Bottom opening fastening means, optionally in the form of a Zip fastener on which the inflatable wall part can be detached to form a shaft extending over the waterline is to be attached.

In principle, an expedient embodiment provides that the shaft has a closure device at one of its ends has, which seals the shaft against water penetration.

909837/0032

If the boat is designed as a rubber dinghy, the opening is in the bottom on the outside of the bowl an advantageous too separately inflatable Wu3afc assigned to the viewing opening secured in the event of a grounding.

An essential feature of the invention is that in addition to the shaft in the boat hull at least one opening is provided in which an actuating element, possibly in the form of a rod with a hook, is guided, which are arranged at the lower end below the boat Has gripping means and a handle at its upper end. This is to achieve that at the bottom of a For example, stones or the like can be moved or plants can be turned to the side to allow animals to enter Finding hiding places and making them visible.

The rod is expedient in a possibly cardanic manner arranged in the boat hull bush axially guided, in this bushing guide means for waterproofing are provided. As a result, the gripping means can also be moved laterally, and the rod can be adapted to the Be pushed down sufficiently far into the water. It it is preferred that two rods and associated bushing arrangements are provided on two diametrically opposite sides of the display insertc albeit according to a training the lead-through arrangements for passage

909837/0032

the rods in the bottom of the boat can be provided with expandable membranes that are connected to the rods, ιο reserves the invention, class also for the rods shafts are available that are guided over the waterline and in which the rods are freely movable. If sockets are provided, there is the option of arranging them on the outside of the ship's side if the boat is sufficiently small. . · ..- '■■

An essential embodiment of the invention on a boat with a throat is that the shaft for the Show insert arranged in the longitudinal center line of the boat and the Ducht is executed penetrating, with hanging device and openings for the passage of gripping inserts, too penetrating the Ducht, are arranged and have shafts to the bottom of the boat in the extension. Here in is the preferred embodiment of the invention. Included it is always pointed out that the Schachty which flows into the throat, two-way towards the lower end flared, while a cover in the form of an optionally with closure elements equipped lid is provided at the upper end in the plane of the ducht.

The invention is explained below using an exemplary embodiment which is shown in the drawing. In this show:

Ducht a circular slideway 7, advantageously under the Sunk level of the throat, arranged in which a ring carrier 8 is rotatably mounted. This ring bearer wears around diametrical Axes 9 »10 pivotable a tubular display insert 11, which is designed in the shape of a channel and is open at the top and a transparent one at the bottom near the bottom of the boat Has disc 12. For example, there are handles at the top 13, 14 ·, 15 arranged with which the show insert can be rotated by the ring carrier 8 revolving in the raceway 7, and then pivoting about the axes 9, 10 are carried out in each direction and in accordance with the expansion of the shaft 6 downwards. The opening 5 is in any case above the waterline of boat 1 even when fully occupied, so that the water in the shaft rises to about half the height. In this embodiment, the weight of the ring carrier 8 is chosen so that it, increased by the weight of the show mission on the annular guide 7 remains, even if the buoyancy of the show insert is effective. Holding guide means can be provided.

The openings 3 »^ which are still arranged in the throat 2 are connected to the boat floor by appropriate shafts and open at the bottom Through these shafts, for example, boat hook-like rods can be passed through, with which the ground is scanned and objects on the Reason moves who can deft.

909037/0032

Ea can be seen that the display insert 11 with the ring carrier 8 can be lifted out easily. A cover is then provided (not shown) that is placed on the slide 7 and the opening 5 can be applied to cover, that the ducht is continuously closed. The same covers can be provided for the openings 3, 4.

For example, the boat has a second ducht 16 on which an observing person can sit.

As shown in dashed lines in Pig, 2, there is the possibility of attaching a boom 17 to the ship's side, which has a guide bushing 18 at its end through which a rod outside the hull, advantageously with a hook at the bottom, can be performed in order to perform any operations on the bottom.

In Pig. 3i in one opposite J ¹ Xg. 2 is shown on an enlarged scale, it can be seen that, for example, under the opening 3 there is also a downwardly widening shaft with the wall part 19. The opening 3 can be surrounded by a slide .20 corresponding to the slide 7, in which a guide ring 21 is removably guided. In this guide ring, a bushing 24 is mounted so as to be pivotable about two pins 22, 23, through which a rod 25

is performed, which has a handle 26 and on the upper end the lower end has a hook-like projection 27. Me rod is movable in its axial direction in the socket «, so that it can be pushed down according to the water depth, but with a loss due to the widening of the handle 26 is definitely excluded.

Fig. 4 shows an example of a partial representation Shaft with the wall part 28 in the hull, the bottom of the boat being indicated by 29. Here is for show use 30 a cardan ^ suspension is provided in such a way that the display insert within a ring 31 by two diagonals Pin 32 is pivotable, which extend between the ring and the wall of the display insert 30. Under right The angles to this are offset by the upper end of the wall part 28, for example by threaded holes, threaded pins 33, 34 out, which enter with their inner end in receiving openings within lugs 35, 36 and optionally can be screwed in. It can be seen that the viewing insert 30 can be deflected radially symmetrically on a handle 37 at the upper end, so that any movement can be followed by animals.

Another easy option for a show shows Pig. 5, in which the shaft is flush with the wall part 38

if shown in side view in Sennitt. Since the Sehau insert 39 can only pivot in one plane perpendicular to the plane of the drawing, the shaft also widens only in this plane, so that it extends in the transverse direction of the boat and kept narrow in the longitudinal direction can. In opposite wall sections at the upper end of the shaft there are projections 44, 45 in passages 40, 41 guided rotatably with outer handles 42, 43. In the interior of the shaft, the approaches are designed like a half-shell. Due to the ability to rotate, it is possible to bring the half-shells into a position that they can follow are open at the top. Then the cylindrical viewing insert 39 can be introduced with diametrical pins so that the Embed pins 46, 47 in the half-shells. Then the approaches 44, 45 are rotated by 180 °, the half-shells migrate around the pins 46, 47 at the top thereof. The resulting buoyancy of the show insert 39 presses the cones in these half-shells and holds the display insert in the forward position.

There is the possibility of elastic locking means between the approaches 44 * 45 on the one hand and the bushings 40, on the other hand to attach, which a releasable Yerrastung result in the two operating positions.
