Roll-up hatch cover

The innovation concerns a roll-up hatch cover.

Well-known roll hatch covers are rolled up on the transverse coaming of the ship, The hinged lids nest inside each other like a hat. Another to the booth The design, which belongs to the technology, slide the lid on the longitudinal coaming and nestle closely together. Finally are Faltdeckei known, which are folded perpendicular to the transverse coaming. There is also one of several lids existing hatch cover to the state of the art, in which the lids are telescoped one below the other. The known Designs are either technically complex or require an opening over the entire length of the ship's hatch, no matter where the hatch over the hold is to be opened. When the telescopic training is In addition, the arrangement of guides lying next to one another is required, which results in a reduction in the hatch width.

The innovation is based on the task of one less technically elaborate hatch cover to produce and at the same time to create the possibility that the hatch at that point or can be opened at least in the vicinity of the point where unloading is to take place, d. H. the disadvantage described with oils to avoid having to gt-open the entire hatch when you want to unload goods at any point.

The goal on which the innovation is based is a roll-up hatch cover According to the innovation achieved in that guides for the rollers on the surface of the hatch cover or against it

sunk over, but vertically exactly over the lower one with the Ship permanently connected are arranged. This makes it possible to use any roll hatch cover z. B. to raise and him from its guide on the longitudinal coaming to the guide arranged on the adjacent hatch cover. Independently of, At which point of the hatch cover the rollers and, accordingly, the guides are attached to the ship, this can be determined Way, either each hatch cover or only part of it can be lifted and placed on the adjacent cover. the So hatch can be opened practically at any desired point or in their vicinity without the need for all of them Operate hatch cover.

Raising the hatch cover can, for. B. done by hand what in particular for inland waterway vessels in which the hatch covers are often made of aluminum materials. But you can also use mechanical aids with which the hatch cover is raised vertically or inclined on the neighboring one Hatch covers can be brought. For the latter variant in particular, it is advisable to use the on the ship to make the guide located pivotable. Then the lid located on the pivoted guide z. B. by hand the next cover can be pushed or pulled mechanically, on the guide of which it then arrives. The pivoting of the related Rail is expediently carried out hydraulically. Compared to the telescope version explained above, there is the additional one Advantage that several guides lying next to one another can be omitted.

Two embodiments of the innovation are shown schematically and by way of example in the accompanying drawings.

The Figg; » 1 - ? show hatch covers with guides arranged on their surface, namely Fig. 1 the closed hatches, Fig. 2 an inclined raised hatch cover, whereby the hatch is opened at the point at which the raised and offset hatch cover was.

The FiKg. 4- and 5 show a hatch cover with guides arranged at the same level as the surface.

In Figs. 1-3, the roll-up hatch covers are each labeled 1. They run with the help of the rollers 2 on the guides 3, which are either attached to the coaming or to the deck. According to the innovation, the hatch covers Λ each have two guides 4 on their surfaces, on which one or more of the adjacent hatch covers can be placed. This placement of the hatch cover can, as already mentioned above, for. B. can be brought about by simply lifting the lid. Another possibility for this is shown in FIGS. 2 and 3, then the guides 5 located on the ship are designed to be pivotable so that they are raised and the respective in Figs. 2 and 3 hatch cover drawn in the middle can be raised on an inclined plane onto the hatch cover drawn on the left in the image plane.

The embodiment shown in cross section in FIG. 5 shows a guide V arranged at the same height opposite the surface of the hatch cover. This arrangement is often desired or required, e.g. when the hatch covers are driven over with forklifts. Then the forklifts not obstructed by the guides. This embodiment is particularly suitable for seagoing vessels where the hatch covers are expediently made of steel.

Claims (2)

S c hat o demands 1) Roll-up hatch cover, characterized in that the guides (4, 4- ') for the rollers (2) on the surface of the hatch cover or sunk opposite, but vertically are arranged exactly above the lower guides (3) which are firmly connected to the ship. 2) Lid according to claim 1, characterized in that the located on the ship guide (5) is pivotable.
