DE102006061384A1 - Insulated porthole, for ocean-going vessels, is a double glazing with a thicker outer disk pane of a larger diameter in the frame in a force fit with a smaller floating disk pane - Google Patents

Abstract

The insulated porthole, for an ocean-going vessel, has a double glazing (S) with disk panes of different diameters. The outer and thicker disk (S1) is at the frame (A) in a force fit and the inner disk (S2) floats. The two disk panes are not pressed together by water pressure. The inner frame can be heated.

Description

State of the art and current problem

There are no thermally decoupled portholes on the market. In medium and large temperature differences between the interior and exterior, creates on discs and frames a significant amount of condensation, which can even cause damage to the interior. In any case, portholes of ordinary design sources of "cold radiation", which affect the living environment very adversely.

The invention for which protection is sought

• 1. Das Glaskomposit (S) besteht aus einer Securitglasscheibe mit großem Durchmesser (S1), einem Hohlraumdistanzring (HDR) und einer dünneren Sekuritglasscheibe (S2) kleineren Durchmessers. Die größere Scheibe liegt kraftschlüssig in der klappbaren Bullaugenklappe (D) oder alternativ im festen Bullaugeninnenrahmen bei Bullaugen ohne klappbarem Deckel. Somit wird die Doppelglasscheibe bei Wasserdruck nicht zusammengepresst, was der Fall wäre, wenn beide Scheiben den gleichen Durchmesser hätten und die innere Scheibe auf dem Rahmen aufliegen würde.
• 2. Das Gehäuse des Bullauges besteht aus einem Außenrahmen (A), der durch die Rumpföffnung geschoben wird, aus einem Schraubring (B), der von innen auf den Außenrahmen geschraubt wird, aus einer Bullaugenglasverschraubung (C), die samt Bullaugenklappe (D) ebenfalls auf den Außenrahmen (A) gedreht wird und letztlich aus einem Deckrahmen (E), der von außen in den Außenrahmen eingesetzt wird. (Bei Rumpfarbeiten kann er einfach herausgenommen werden, was Überholungskosten spart.) Das Besondere an diesem Deckrahmen ist die Dämmfüllung (4) zwischen ihm und dem Außenrahmen und die umlaufende Moosgummidichtung (5) am Deckrahmentrichterende, die ihrerseits direkt auf die Doppelglasscheibe (S) stößt und dichtet. Es verbleiben keine Kältebrücken.
• 3. Für ganz extreme Temperaturbereiche ist der innere Schraubring (B) beheizt (Heizelement 6), womit das ganze Bullaugensystem temperiert wird.
• 4. Ein Einschubring (H) kann individuell gestaltet werden, was dem Bullauge eine persönliche Note verleiht.

Our new porthole now has four new construction features:

• 1. The glass composite (S) consists of a large-diameter Securitglasscheibe (S1), a cavity spacer ring (HDR) and a thinner Sekuritglasscheibe (S2) smaller diameter. The larger disc is frictionally locked in the folding porthole flap (D) or alternatively in the fixed bull's eye inner frame in portholes without hinged lid. Thus, the double glass plate is not compressed in water pressure, which would be the case if both discs had the same diameter and the inner disc would rest on the frame.
• 2. The housing of the porthole consists of an outer frame (A), which is pushed through the hull opening, from a screw ring (B), which is screwed from the inside to the outer frame, from a porthole glass fitting (C), which together with porthole flap (D) is also rotated on the outer frame (A) and ultimately from a cover frame (E), which is inserted from the outside into the outer frame. (For hull work, it can be easily removed, which saves on overhaul costs.) The special feature of this deck frame is the insulation filling ( 4 ) between it and the outer frame and the circumferential sponge rubber seal ( 5 ) at the Deckrahmentrichterende, which in turn directly on the double glass pane (S) abuts and seals. There are no cold spots left.
• 3. For very extreme temperature ranges, the inner screw ring (B) is heated (heating element 6 ), which temper the entire bull's-eye system.
• 4. An insert ring (H) can be designed individually, which gives the porthole a personal touch.

Industrial Applicability

• • On Yachts of any size.
• • Cruise ships

advantages

• • Keinerlei Kondenswasserniederschlag an Glas und Rahmen
• • Druckfestes Fenster auch bei Doppelverglasung
• • Doppelte Dichtung
• • Beste Schallisolation
• • Äußerst wertige Optik in hochglanzpoliertem oder verchromtem Edelstahl oder in Messing ohne jede sichtbare Verschraubung und zahlreichen gediegenen Radien, die die Optik als aus „einem Guß" erscheinen lassen.
• • Auch in eloxiertem Aluminium zu fertigen
• • Durch individuellen Einschubring ergibt sich eine persönliche Note

The advantages achieved by the invention are as follows:

• • No condensation of glass and frame
• • Flameproof window even with double glazing
• • Double seal
• • Best sound insulation
• • High quality optics in highly polished or chromed stainless steel or in brass without any visible screw connection and numerous solid radii that make the look appear as a "cast".
• • Also available in anodised aluminum
• • Individual insertion ring results in a personal touch

Ways to execute

First a hole is cut in the hull (R) into which the outer frame (A) with sealing material ( 1 ) how Sikaflex is glued. It is important to ensure that the angle of rotation is the desired, because namely the Bullaugenglasverschraubung (C) is fixed in a certain angle of rotation on the outer frame (A). This is for the correct sealing between the two parts by means of O-ring ( 2 ) indispensable.

The outer frame (A) is turned as a turned part of a stainless steel or brass blank. The screw ring (B), also a turned part, is now screwed in using two holes ( 3 ). Towards the fuselage seals an O-ring ( 7 ).

The porthole glass fitting (C) and the porthole flap (D) are turned / milled parts or castings with subsequent surface treatment. They are screwed on as a hinged connection with closing and sealing action. The glass composite (S) is glued in accordance with the standards in the automotive industry. (adhesive joint 9 )

Ultimately, the outer deck frame funnel (E), which is a composite unit made of stainless steel or brass and a good insulating and dimensionally stable plastic ( 7 ), inserted and brought in with the help of plastic screws (F). The plastic screws are covered by stainless steel screw caps (G).

With a fine Sikaflexfuge ( 8th ) the deck frame hopper is sealed.

The decorative, custom-made and insulating insert ring (H) visually covers the insulation filling ( 4 ) and gives the porthole the individual touch. The slip ring (H) may also be wide enough to cover the plastic screws (F) and avoid the plugs (G) when more prominence is required. The insertion ring can be made, for example, of wood, inlaid wood or plastic with engravable metal surface. The individual note has no limits.

Claims (4)

Special porthole system, characterized in that insulation effect is achieved by means of a double-glass Securitscheibe with different pulley diameters, wherein the thicker outer disc rests on the frame frictionally and the inner disc floats freely, so that the disc composite is not compressed under water pressure. Special porthole system, according to claim 1 thereby in that the actual porthole construction through an outside patched, additional Deckrahmentrichter with insulating material sheath, the between the funnel and the porthole construction is placed, supplemented, whose circular seal hits an area on the disk, in the insulating effect of the disc without loss effective is, whereby "cold spots" are prevented. Special porthole system, according to claim 1 thereby in that the system for extreme temperature ranges, by means of in the screw ring integrated Elektroheizpackung, tempered can. Special porthole system, according to claim 1 thereby in that the system by using an individual Insertion ring receives a customer-related note.
