Description

DESCRIPTION

Device for unlocking a hatch or shutter or door for closing or sealing openings in marine vessels or ships

field of invention

The present invention relates to a hatch or shutter or door unlocking device for closing and sealing openings in maritime vessels or ships, in particular, but not necessarily, military ships.

The present invention further relates to a hatch or shutter or door control device for closing and sealing openings in maritime vessels or ships.

Background

Boat shutter closing devices adapted to hermetically close, that is, seal, the openings present in the decks of boats are known.

For example, US2460961, US6123370, US5333920, WO2010033026, US6675536, US5333920, NL8303636, DE630669, FR375410, FR866063, US2009033103, 393 disclose how to manufacture sealed doors or shutters with multiple closing mechanisms with controls that in some cases are even very complex.

All of these documents have solved many problems over the years but are increasingly complex; The more secure the closures and the better the sealing, the more unsuitable such closures will be for emergency opening.

Indeed, it is very necessary to be able to open these doors or blinds, at least from the bottom up, that is, from the inside out, when the closing mechanism is defective or blocked.

For example, the need to open a shutter can be foreseen in an emergency after an accident or a collision of the ship with damage to the structures that prevent the normal operation of the closing and opening mechanism of the shutter. In this unfortunate case, the only possibility offered by the known solutions is to open the structure of the blind, provided that this is still possible and it is not deformed to the point of being impossible to dismantle it, and access the mechanism, and in particular, the closing rods, either by forcing them open or cutting them.

It is easy to imagine the enormous amount of work required and the impossibility for operators to predict whether this operation is really feasible.

As is easy to imagine, many times the only solution is to cut the sheet metal of the blinds.

It is therefore still very necessary to open a blind from the inside also if the closing rods are defective, for example if the mechanism is deformed or completely damaged.

They can also be considered, for example, ships for military or defense use in which impacts can deform the structure of the shutter and/or the mechanism, not allowing sufficient opening movement of the shutter.

In particular, it is still very necessary to be able to open a blind whose opening mechanism is damaged, avoiding the use of particular tools that are no longer part of the blind assembly.

In addition, mechanisms for opening and closing doors or shutters on ship decks are known.

For example, US4620733, GB191023663, GB127912, ES2192910 disclose some of these mechanisms.

These solutions, although satisfactory from many points of view, do not prevent accidental damage to the closing rods. In particular, the frame structure and perhaps also the rods themselves would be damaged if the closing rods were manipulated and accidentally extracted with the blind open, in case of sudden closing with the rods extracted, i.e. protruding from the structure in a of blind box. Therefore, a particular actuation precision of the shutter closing mechanism is still very necessary to limit the operator's effort and at the same time a solution capable of preventing the rods from moving to the extended or closed position when the shutter is open, the rods being dangerous and prone to damage by accidental closing of the blind, which would cause them to hit the frame.

Therefore, the need is felt to adopt a system of automatic locking of the rods in the retracted position with the blind open, to prevent the blind from being closed incorrectly with the rods in the extended position with consequent damage to it.

Solution

These and other objectives are achieved by a device according to claim 1 and by a method according to claim 9.

Some advantageous embodiments are the subject of the dependent claims.

From the analysis of this solution it is clear that the suggested solution allows opening a blind whose opening mechanism is damaged, avoiding the use of particular tools that are no longer part of the blind assembly.

Thanks to the proposed solutions, it is possible to continue opening a blind from the inside even if the closing rods are defective, for example, if the mechanism is deformed or completely damaged.

Even more, by virtue of the suggested solutions, it is possible to have an actuation mechanism for the closing mechanism of the blind that allows limiting the effort of the operator and at the same time a solution capable of preventing the rods from moving to the extended position or when the blind is open, the rods being dangerous and prone to damage by accidental closing of the blind which would cause them to hit the frame. Furthermore, by virtue of the suggested solutions, it is possible to adopt a system of automatic locking of the rods in the retracted position with the blind open, to prevent the blind from closing incorrectly with the rods in the extended position with consequent damage to it.
