"Seal in particular for hatch plate or the like".

The present invention relates to improvements and modifications to the seal and the sealing device the hatches of a ship or similar access openings in particular according to claims 1 to 5 and 4 of the main patent, and in particular certain embodiments of these and the various applications and uses resulting from their practical Realization will follow.

In the main patent, a seal has been described that is hollow and is in the form of a continuous, flexible tube carrying a constant amount of a gas, such as air · ■ contains and is self-contained. The main patent also describes a device for tight closure for Ship hatches with two removable panels or lids in the closed state along a transverse connecting or sealing line and on the one hand with each other a circumferential seal, which works together with the hatch edge, and on the other hand provided with a transverse seal

are that extend over the entire broad side of the said plate extends and thereby on each side "up to the circumferential seal runs to cooperate with the corresponding transverse seal of the other plate. This "known structure has in particular the specialist part that the entirety of the seals of each plate consists of at least two individual parts that are assembled while retaining their individual character as an independent organ. this has the consequence that the manufacture and assembly is relatively complicated and consequently expensive.

The main aim of the additional application is to remedy these shortcomings and difficulties and to create a new industrial one To create a product that consists of a single-body sealing system, which is characterized by a single tube which is manufactured in one piece and an at least approximately annular one Has overall shape that has at least two areas, each essentially in the shape of a flat or twisted bilge Is have and deal with each other on each side with the appropriate Unite ends of their respective bow branches by means of at least one pair of tubular binding elements, one of which each has three consecutive knees, two of which are obtuse angled and are coplanar and one, for example, is substantially rectangular, and each lying in two planes of which one runs parallel to the branches of one of the mentioned areas, while the other level contains the other area.

The new seal according to the additional application can advantageously be formed from several segments or parts,. for example by casting, after the press spinning process or manufactured separately from one another by the draw spinning process and then assembled.

In the following the invention is attached with reference to Illustrations explained in more detail. The following applies to the images:

- Figure 2 shows in a partial view from above and in a horizontal section along the line II-II of Figure 3 part of two hatch panels arranged side by side in their substantially horizontal position for tight closure,

with these plates through, the seals of their opposite one another Surfaces lie against each other;

- Figure 3 shows in a partial side view in one vertical section along the line III-III of the Eigur 2, the two aforementioned plates;

the Eigur 4 is a partial view in section along the line IY-IV of Eigur 2; and

- The figure 5 shows in a partial view in section along the line V-V of the Eigur. 3 the outer surface of the inner transverse wall.

In the embodiment shown in FIG. 1, the seal, which is indicated in a general manner by the reference number 101 is characterized, two parts 102 and 103, which are essentially each have the appearance of a bracket. These two parts are parallel to two mutually perpendicular planes and are with each other connected on each side by the corresponding ends of their bow branches 104, 105 with the help of tubular connecting elements 106, which are preferably inclined so that a unit arises that is approximately the shape of a twisted, polygonal ring Has. The transversely directed region 107 of the bow-shaped part 103 is with the branches 104 of the bow-shaped part 102 on each side connected by a twisted intermediate area with three successive knees, two of which 109, 110 are obtuse-angled and lie in the same plane, while the third knee 111 is substantially rectangular.

The different segments or sections that make up this seal 101 and in particular the transverse regions 107, -108 and the side branches 104, 105 are preferably straight. The four corners 111, 112 are preferably rounded, while those in the same Knees 109, 110 lying flat, preferably ·: Are acute-angled. For example, each connector 106 is related to the two mutually perpendicular planes containing the two bow-shaped parts 102, 103, inclined by 45 °. The different sections that the Form a closed ring-shaped seal, can be connected to one another, for example, by gluing or vulcanizing.

Figures 2 to 5 illustrate the application of the seal 101 to two plates 113, 114, which are intended to be a To close ship hatch 115, the opening of which is opened by a frame

509832/0808

is correct, which is caused by the longitudinal and transverse envelopes 116. on the sill bar 117 has the flat sealing rib 118 arranged, which runs around the hatch and has the task of compressing the bow-shaped part 102 of its seal 101. Every plate is along their lower edges and the front edge are provided with a trough-shaped channel 119 which runs along the outer edge of the plate and serves to accommodate the one-piece seal 101. To this Purpose, the trough-shaped channel 119 has a seal 101 corresponding Shape and is accordingly designed in particular in the form of an inverted trough in the lower surface of the plate. These trough-shaped channel 119 that extends downward from the lower. Border of the plate and is bounded to the front by its end wall, consequently forms a continuous channel in the form of one in itself closed circuit for receiving the seal 101.

Each plate therefore has an area 102 or 104, 106, 107 of the sealing hose arranged on the circumference, which is in a corresponding area of the trough-shaped channel 119 with the side walls 120 and the outer outer wall 121 is inserted, as well as a transverse sealing area 103 'or 105, 108, the built into a corresponding area of the trough-shaped channel 119 which is formed on the outside on the inner, transversely directed end face 122 and above the sealing edge region 102 and their associated channel area 119 lies and thereby on each Side of the plate slopes down to the latter.

In order to achieve a tight contact with the inclined parts 106 of the seal 101, the sealing rib 118 has the along the two opposite longitudinal edges of the hatch on each side, perpendicular to the vertical sealing plane an area between two plates 113, 11 4 in the closed position 123, which is an essentially triangular, designed in the form of an upwardly protruding wedge and essentially to the aforementioned Sealing plane, symmetrical.Eckstück forms, whose vertex height substantially corresponds to that of the obtuse-angled, upper knee 109 of the seal 101, while the protruding half-angle at the apex of the part 123 essentially corresponds to the outer angle of the aforementioned obtuse-angled, upper knee 109. Thanks this Execution fills each vertically protruding corner piece 123 in the

509832/0808

In FIGS. 3 and 4, the closing position of the plate ends is shown entire space from the sealing rib 118 and the inclined areas 106 of the seal is delimited by penetrating into these inclined areas 106 in a certain way.

The maximum deformation or degree of intrusion of the edge area of the seal caused by the sealing rib T18 is caused, is advantageously by stops 1 24, which are arranged on the coaming 117 and on which the circumferential, inner outer edge of each plate comes to rest when this is in its tight closed position, or limited by the direct EontaEt of this edge on the said bar.

Instead of an asymmetrical shape in relation to a transverse plane (parallel to the transverse area 107 of the bow-shaped part 103 and perpendicular to the branches 104) as in Figure 1, the Seal 101 can also be symmetrical to such a center plane and at the same time with its other outer transverse area 108 or bow-shaped Part 102 be set up symmetrically, like the bow-shaped flap Area 103. This bow-shaped part 102, 103 can be any '' For example, have a rectangular shape with straight or curved, flat or twisted areas.
