CARGO SHIP DOOR SUPPORT AND SEALING ARRANGEMENT

The present invention relates to a carrier cargo hatch support and sealing arrangement for supporting a substantially rectangular cargo hatch and any payload thereon and sealing the hatch against the ship's karel, which arrangement comprises one or more support blocks substantially near the outer edges of the hatch and elongated seal.

The purpose of the support piece is to carry the weight of the hatch and any payload on it, so that the hatch can move in the direction of the carvel (ship hull deformations at sea). Further, a piece of bracket allows the hatch and. the distance between the carpels is kept constant regardless of the load, so that the seals work best.

For this purpose, e.g. a solution in which brackets are secured to the outer edge of the hatch, for example two brackets on each side of the hatch, and an elongated rubber seal circulating near the outer edges of the hatch to seal the hatch against the ship's carve. This allows the hatch to be supported and sealed so that movement between the hatch and the ship's carvel is possible, which is important in the event of: - · seafaring. The disadvantage of such a solution, however, is its large space requirement, which means that the extreme dimensions of the cargo hatch are unnecessarily large: 25 due to the protruding brackets. This also requires larger dimensions for the carvel. The structure of the cargo hatch in this known solution is also quite complicated due to the separate bracket brackets. Installing hatch covers, especially aligning the pigeon, is cumbersome and time consuming.

It is an object of the present invention to provide a novel cargo carrier • • · hatch support and sealing arrangement without the above drawbacks. The arrangement according to the invention is characterized in that the support pieces are water-tightly connected to the seal. In this case, there is no need for separate brackets that are attached to the outside of the hatch: · · · and protrude from the hatch, but require less space than the hatch. The hatch covers can also be made lighter and more manufacturing friendly. Installing the hatches is also easier than before.

An advantageous embodiment of the invention is characterized in that the bracket pieces are at least partially mounted inside the seals.

Another embodiment of the invention is characterized in that the gasket and its mounted brackets are secured to the cargo hatch, and that in the dormant state of the hatch the lower surface of the bracket is higher than the lower surface of the gasket.

Yet another embodiment of the invention is characterized in that, when the hatch cover 10 is in use, the underside of the carrier block is substantially in the same plane as the seal against the carvel.

Another embodiment of the invention is characterized in that the underside of the support piece is of sealing material. This provides a continuous seal 15 around the entire cargo hatch, since there is also a seal at the support piece. In addition, this allows for a completely corrosion-free support and sealing arrangement.

Yet another embodiment of the invention is characterized in that a portion of the gasket and the bracket piece form a single discrete unit which can be secured in place, in particular the cargo hatch, by means of fastening elements in the bracket, such as threaded pins and suitable nuts.

Figure 1 thus shows a prior art support and sealing arrangement for the cargo hatch 1. As is known, the cargo hatch covers a cargo space opening which is not shown in detail in the drawings. As is known, brackets 2 are fastened to the outer edges of the hatch cover 1, the mating surfaces of which rest against the ship's carapace 3 with the hatch cover in place. The number of bracket pieces may vary, but in the example shown in Figure-20 there are two on each side of the hatch. As shown in Fig. 2, an elongated rubber seal 4 is attached to the groove formed at the lower edge of the hatch, which wraps the entire hatch and seals the hatch watertight against the carapace 3. The disadvantages of this solution have already been listed earlier in the description.

as in the known solution. However, the bracket pieces 5 are integrated within the tongue-and-groove 4. The number of bracket pieces may be the same as in the known solution. The number depends on the structure of the hatch and the expected load t I »'· *'. It is essential that, in the solution according to the invention, they are not placed on the outer edge of the cargo hatch but inside the seal. The structure of the bracket may vary as such. Preferably, however, at least in part it consists of 35 metals. In addition, it is advantageous to make the lower surface of the support piece a sealing material to provide a continuous sealing effect around the entire hatch. The gasket * ··· 4 is secured in the same manner as in the known solution to the groove 4 110179 in the cargo hatch 1 as shown in Figure 4. As will be further seen in Figures 3 and 4, notches 6 are provided at the lower part of the outer edge of the cargo hatch, which allow a slight lateral movement of the carrier pieces in the sea. The canner piece may be of a sliding type or one that allows movements with internal deformations. The sealing rubber profile 4 may be in accordance with conventional sealing solutions, i.e. sliding on a mating surface or pressed against a sealing iron.

Fig. 5 shows one possible solution for easy installation of the integrated bracket piece and seal 4. They form a recess of a certain length, which as such is secured in its slot in the groove in the cargo hatch 1. After this piece of bracket / rubber gasket, the gasket profile normally continues in both directions. The bracket / rubber gasket member is provided with two threaded pins 7 which are inserted through respective holes in the trunk lid groove and locked in place by nuts 8 (Figs. 7 and 15 8).

Figures 9 and 10 show the so-called latch hatch. dormant state, i.e. seal 4 is not loaded. This is the case, for example, when the cargo hatch is lifted by a crane. The lower surface of the support piece 5 is then higher than the lower surface of the gasket. Figures 7 and 8, in turn, show a situation in which the hatch cover is installed, a so-called operating situation. Thus, the underside of the bracket piece 5 is substantially in the same plane as the seal 4 against the pigeon. Since the lower surface 5 of the bracket piece is made of sealing material, continuous sealing around the entire hatch cover is possible.

; In turn, as previously described, the strut blocks ensure that the load on the seals remains constant, which ensures optimum sealing.

It will be apparent to one skilled in the art that the invention is not limited to the exemplary embodiments set forth above, but may be varied within the scope of the appended claims. For example, it should be noted that the solution described above wherein the sealing rubber 4 is located in the cargo hatch 1. Equally, the seal could also be mounted on the carapace, thereby sealing against the underside of the cargo hatch. Also, the bracket pieces do not necessarily have to be integrated inside the gasket, ·: ··: but they can be joined together in a water-tight manner by other means, for example successively in the same longitudinal line. The essential thing is that the gasket and bracket \. the piece forms an integrated, waterproof and space-saving whole.
