DE2923248A1 - Safeguarded lead-aperture for deck opening in ship - has superposed plates rotated relatively to vary size of aperture and to close it completely - Google Patents

Abstract

The safeguarded lead-aperture is used esp. as a deck opening in a recreational or small utility-watercraft. It has two superposed plates (11,12) embodying apertures (18,20, 17,19) which by relative rotation can be made to provide a varying-size through passage or to close the opening. The apertures are configured firstly (19,20) to permit passage of a fuel hose coupling block, on the other (17,18) to fit closely around the hose. There is a spring (15) around a spigot (16) in the lower plate for a clamping bolt. This spring acts on a lug (14) underneath the upper part projecting through a slot (13) to bias the plates towards the closed position.

Description

Safety opening for the fuel

hose from the separate tank to the outboard motor in sports boats and small water vehicles.

The present invention relates to a passage for closing a Opening, especially in the deck of sports boats or boats with an outboard motor, by means of two round passage plates lying one above the other, which are activated by a rotary movement are mutually displaceable and thereby optionally close a passage opening or open.

Many pleasure boats (motor and sailing boats as well as smaller water utility vehicles) are now mainly or alternatively used by outboard motors with a separate Fuel tank powered.These non-permanently built-in transportable tanks are in most cases in the stowage space on the stern post, which is closed by a hatch a boat housed.

The fuel is supplied to the outboard motor attached to the stern via a fuel line permanently installed on the tank (rubber hose approx. 11mm 0) at the end of which a coupling piece (dimensions 35mm x 25mm) ensures the connection to the motor.

Because the transportable tanks after completing an exit for safety reasons should be brought ashore from the boat, the problem arises that in proportion to lead a much larger coupling piece through the deck to the fuel line without that afterwards if only the fuel line is still in the opening or after removal of the tank the opening is completely empty, water by rain or can penetrate by washing over the deck.

Currently, fuel lines through decks are passages with a clear width up to 90 mm, which can only be closed after removing the cable , i.e. that when the outboard motor is operated in rain or in rough seas, or when the upper deck is washed over, water can penetrate into the hull.

In the following the invention is based on schematic drawings an exemplary embodiment explained in more detail.

It shows: Pigur 1 in a side view of the security deck passage on board a boat, the passage plates in the "closed position" Figure 2 in a plan view of the position of the passage plate in the closed state Figure 3 in a plan view opposite the position of the passage plates after a rotary movement clockwise until it stops, in opening position 1, to carry out the coupling piece.

FIG. 4 shows the position of the passage plates in a plan view a turning movement (back) clockwise, in opening position 2, in which the fuel line clamped, or. the passage opening for the coupling piece is closed again is.

The safety deck passage shown in the drawings is for Closing a passage opening for the coupling piece of a fuel line from the separate fuel tank to the outboard motor.

The deck of the boat is marked 1o. The lower passage plate 11 is firmly attached to the deck with four countersunk screws 12 is fixed in the center on the lower passage plate 11 8o that it is can rotate around its own axis.

In the lower passage plate 11 there is a four-circle-shaped Elongated hole 13 through which the bolt 14 attached to the upper passage plate 12 is passed The elongated hole 13 limits the rotational movement of the upper passage plate with the bolt 14 12th

Through the center bolt 16 seated on the lower passage plate the spring 15 is fixed, which opposes the upper passage plate 12 via the bolt -14 clockwise in the closed position or in the open position 2 (in Open position only when the fuel line is passed through the passage is) with the upper passage plate 12 a counterclockwise rotation Carried out to the stop, the passage opening 19 is the upper one Passage plate 12 in alignment with the passage opening 20 of the lower passage plate 11 and the coupling can be passed through the passage.

(Open position 1) As soon as the fuel line is in the passage is located, the spring 15 provides over the bolt 14 and the upper passage plate 12 for closing the safety deck passage until the fuel line is stuck.

The result is opening position 2, i.e. passage opening 17 of the upper one Passage plate 12, together with passage opening 18, forms the lower passage plate 11 the opening position 2 sealing on the fuel line Blank page

Claims (3)

Ansi> rllohe 1st security deck passage for closing an opening especially in the deck of sports boats and smaller watercraft, by means of two overlying passage plates 11 and 1?, the passages by rotating movement different sizes (17/18 and 19/20) or close them completely. 2. Safety deck passage according to claim 1, characterized in that a spring the constant position of the "closed position" as well as the "open position 2 "guaranteed and an automatic opening of the safety deck opening makes impossible. 3. Safety deck passage according to claim 1 and 2, characterized in that the specially designed throat shapes 17/18 and 19/20 in throat plates 11 and 12, enable the much larger coupling piece by means of a rotary movement to run a fuel line through the deck of a boat without going after it process an opening 'remains in the deck of the boat.
