DESCRIPTION

Technical field of the invention:

The present invention refers to the field of the different industrial techniques and to the transports such as vessels and, referring to this, to rescue equipment at the sea or other aquatic environments.

In particular, this invention refers to a rescue suit for shipwrecks with high functionality and insulation that allows using walls of high thermal isolation without this affecting the access of the shipwreck survivor into the suit and his mobility within it, which is facilitated by a front protrusion which opening defines the adjacent parts that facilitate the access and exit and has an inner hood fixed with its facial opening, maintaining the protrusion within the limits of protection of an unfoldable sleeve that is unfolded through a passage of the outer cover, all this complemented by a suitable headpiece fixing and great mobility in the rest of the suit.

The problem at the basis of the present invention is to solve the problem of the difficulty of effecting the movements of entry through very narrow openings and quick placement of salvage suits with thick insulation walls, as well as the lack of protection around said openings of said salvage suits, of the already known salvage suits.

The problem is solved with a salvage suit according claim 1.

Background of the invention:

None of the known rescue suits has an access opening to the inner cavity of the suit that is arranged in a front protrusion that allows a great opening of said access opening, facilitating both the access and exit of said inner cavity.

The mentioned protrusion, together with the inner hood, is within a protection area defined with an unfoldable sleeve that, upon unfolding, protects both the facial opening of the hood and the access opening of the protrusion. As the receptacle is spacious, different movements can be made inside the suit. For example: take the legs out of the suit legs toward the main part of the suit, take the arms out of the sleeves, change the different floating positions in order to be more comfortable, etc.

The structure of the insulating walls, preferably based on alveolar layers, not only allows a proper thermal insulation and a greater buoyancy capacity, but also allows a sectorial differentiation of its walls. This sectorial differentiation (micro-alveolar areas, macro-alveolar areas, areas with different density alveoli, etc.) allows achieving a differential sectorial insulation and a differential sectorial functionality (for example: micro-alveolar areas where a greater mobility or flexibility is required).

The capacity of flotation given by the alveolar sheets, the hermetic chambers and the body receptacle keep the suit almost completely out of the water, and this diminishes the area of body contact with the water and prevents the body from being exposed to cold, when the water temperature is low.

This suit allows flotation with almost the whole body out of the water, and this allows swimming on one's back or on one's chest very easily (and so it is easy to face even opposite wind and/or current), being the additional advantage that, in case of a puncture, tearing or flooding, the suit inner bladder is not lost, as we also have the alveolar layers, the hermetic chambers and the body receptacle air.

The differential sectorial functionality is also increased with the presence of joint folds.

On the other hand, the incorporation of separated headpiece outer cover and body outer cover, maintains a surrounding passage free through which the unfolding of the unfoldable sleeve is produced. Furthermore, said body cover can include drainage passages to prevent the accumulation of water inside it, hindering user's movements.

At the same time, the wearer protects his face, neck, hands and arms, he has a 100% hermetic barrier against water, and he gets an adequate protection against hypothermia. Consequently, the wearer can stay longer in cold water. Brief description of the drawings:

Detailed description:

In general terms, the present invention refers to a rescue suit for shipwrecks with high functionality and insulation that includes a front protrusion (3) that, finished in an access opening (30) to the inner receptacle or cavity (10), includes hermetic closing means (32) applied to its curved edges (31), which separate two adjacent parts - a thoracic adjacent part (34) and a headpiece adjacent part (33) -, that are functionally movable until reaching the expansion of the transversal access opening (30); in the front protrusion (3) there is an access opening (30) to the inner receptacle or cavity (10) ad a facial opening (50) that are independent; around the facial opening (50), the structure of insulating walls (2) includes a hood (5) and both openings, access (30) and facial (50), are surrounded by an unfoldable sleeve (4) that is projected from the structure of insulating walls (2); the outer cover of protection includes an outer headpiece cover (7) that covers the hood (5) and an outer body cover (6) that are separated by a frame passage (9) through which said unfoldable sleeve (4) is capable of unfolding, until forming an environmental protection over said headpiece hood (5) and over said access opening (30).

In general, the present salvage suit (1) has the capacity of containing the body of a person in its inner cavity (10), giving thermal and hydrological protection and forming a flotation unit. This suit (1) defines a receptacle according to the anatomic form of a person, but with the sufficient width to allow, such as a floating mini-cabin, that the person moves within said receptacle. It includes the structure of insulating walls (2) and an outer cover, both in the body and headpiece part, as well as in the trouser legs (15) and arms (13).

In particular, this suit (1) includes an access opening (30) to the inner receptacle and a facial opening (50) that are independent, one with regards to the other.

Around the facial opening (50), the structure of insulating walls (2) forms a hood (5), while around the access opening (30), said structure (2) can be plain or form a front protrusion (3).

In the front part (11) of the body presents a front protrusion (3) that ends in a transversal access opening (30) of curved edges (31) that constitute de access to the inner receptacle (10).

This transversal access opening (30) has hermetic closure means applied to its curved edges (31), which separate two adjacent parts (33, 34), that are functionally movable until reaching the expansion of said transversal access opening (30).

More particularly, the front protrusion (3) forms a tapered initial part, as a frame, from which the walls that form the adjacent parts (33, 34) are extended to the transversal opening (30) of curved edges (31a, 31b). These parts (33, 34) adjacent to the transversal opening (30), include a thoracic adjacent part (34) - ending in thoracic curved edges (31b) - and a headpiece adjacent part (33) - ending in headpiece curved edge (31a) - in which there is a headpiece opening (35) that communicates with the hood (5).

The possibility that the headpiece adjacent part (33) be less protruded than the thoracic adjacent part (34) has been foreseen. In this way, the minor protrusion of the headpiece adjacent part (33) facilitates the insertion of the user's head through the headpiece opening (35) that communicates with the hood (5).

From the wall structure viewpoint, the front protrusion (3) can be formed of a structure of isolating walls (2) that includes one or more alveolar walls (20).

Apart from the thermal insulation, the adjacent parts (33, 34) have an structure of insulating walls (2) which flexibility allows the divergent dumping of said adjacent parts (33, 34), which is facilitated due to the presence of some corners (31c) in the curved edges (31). In this way the expansion of the transversal access opening (30) can be easily produced, which may then be closed with a hermetic closing means (32) arranged in the mentioned curved edges (31).

In an embodiment, the front protrusion (3) is formed by a structured piece in insulating walls (2) which union edges (36) are joined to the rest of the front part (11). This front protrusion (3) is arranged so that, with the union of its ends (37), a frame which curved edges (31) define the access opening (30) is formed.

The mentioned union ends (37) are preferably oblique so that they converge towards the access opening (30). In this way, the frame edges behave as fitting invitation edges that facilitate the introduction of the user within the suit receptacle (1).

In this case, furthermore, the headpiece opening (35) is joined to the headpiece base (54) of the inner hood (5).

On the other hand, both openings, access (30) and facial (50), are surrounded by an unfoldable sleeve (4) that is projected from the structure of insulating walls (2).

The protection outer cover includes, at least, an outer headpiece cover (7) that covers the inner hood (5) and an outer body cover (6) which outer cavity (61) hosts the structure of insulating walls (2). Therefore, the outer cover covers the body [front part (11) and dorsal part (12)] and the limbs [upper limbs (13), mittens (14), trouser legs (15) and feet (16)]. In different areas, the covers (6, 7) are related to the structure of insulating walls (2) by means of elements suitable for that purpose such as, for example, detachable closings (23).

The headpiece cover (7) and body cover (6) are separated by a frame passage (9) through which the mentioned unfoldable sleeve (4) is capable of unfolding, until forming an environmental protection or protected environment over the headpiece hood (5) and over the access opening (30). More specifically, the frame passage (9) is found between the body edge (62) of the body cover (6) and the headpiece edge (72) of the outer headpiece cover (7).

In an adjacent manner to the mentioned frame passage (9), in the upper part of the body cover (6), the possibility of applying one or more cervical floats (63) was foreseen. For example, in the area adjacent to the body edge (62) of the upper opening (60) of the outer body cover (6), in a way that they are placed behind the hood (5) and help maintaining the head of the shipwreck survivor held high when he is laid down, floating in the water. This outer unfoldable sleeve (4) has a base union (40) that links its unfoldable walls (41) with the structure of insulation walls (2). The possibility that an elastically unfoldable member can be available - equipped with an elastic body (45) finished in unfoldable limbs (46) - that acts as unfolding support (44) of said unfoldable sleeve (4) has been foreseen. It has also been foreseen that this unfoldable sleeve (4), in its end edges (42), has end closing (43) means of it outer opening, which improves the environmental protection it provides.

The headpiece cover (7) has, at least, a retention or holding means that relates the skirt (71) to the structure of insulating walls (2). This retention or rear fixing means (78) can be of quickly opening and closing as, for example, a union of ^" Velcro ^" or thistles type.

On the other hand, the inner hood (5) is related to the outer headpiece cover (7) around the inner facial opening (50) from which the face of the user appears.

Furthermore, the headpiece cover (7) and the hood (5) are under the influence of a traction arrangement (74) that, from linepull connections adjacent to an outer surrounding area (70a) to the outer facial opening (70), is capable of exerting pressure of facial integration over the inner surrounding area (51).

The traction arrangement (74) acts as from the influence exerted by a rear convergent arrangement (75), to which some linepull branches converge that connect the linepull connections with the rear convergent disposition (75).

The convergent arrangement (75) and the traction arrangement (74) are mounted in the inner part of the outer headpiece cover (7) of the suit (1), acting over the hood (5) through the connection between the hood (5) and the headpiece cover (7). This connection is done through the hermetic structure (53), that links the inner union (52) of the hood (5) with the outer surrounding area (70a) of the outer headpiece cover (7).

In one embodiment, the traction arrangement (74) includes fixed linepull connections (745) placed beyond the middle area - for example at the rear area - of the outer headpiece cover (7), from which they are capable of exercise stretching over the outer surrounding area (70a) of the outer facial opening (70).

The traction arrangement (74) acts as from the influence exercised by the stretching strips (752) that, from the rear convergent arrangement (75), connect, at least, part of said fixed linepulls (745), as can be seen in the corresponding figures.

In another embodiment, the stretching strips are elastic means that maintain the traction arrangement (74) usually tightened and exercising constant stretching.

In another embodiment, the traction arrangement (74) includes traction strips (741) related to the surrounding linepulls connections (740) fixed to the outer surrounding area (71) of the outer facial opening (70). Instead, the convergent arrangement (75) includes free rear connections (750) through which both said traction strips (741) and stretching strips (752) pass. On the other hand, the convergent arrangement (75) includes, at least, a fixed rear connection (751) [through fixing of the linepulls (77)] through which stretching strips pass (752)].

More particularly, in an embodiment, the traction arrangement (74) includes some anterior-posterior traction strips (741) that, as of the links or linepull connections (740) of the outer surrounding area (70a) to the outer facial opening (70), exercise their action towards the converging arrangement (75).

The linepull connections include the corresponding linepull connections (740) fixed to said outer surrounding area (70a) of the outer facial opening (70), while the convergent disposition (75) includes rear connections (750, 751) through which said traction strips (741) remain under the influence of some stretching strips (752).

Each stretching strip (752) has a link or front stretching connection (742) and a front or anterior passage (744) through which the pulling end emerges (753) from said stretching strip (752).

To maintain the adjustment (73) of the system, after producing the stretching, the use of means of positional lock (756) [for example, the ones named TANCA type] has been foreseen, that, applied to the pulling ends (753) of the stretching strips (752), produce a lock against the front part (11) of the hood (5) or against the eyelets of the front passages (744), preventing the loosening of the system.

In another embodiment, the traction disposition (74) includes some elastic anterior-posterior traction strips (741) that, as of the links or linepull connections (740) of the outer surrounding area (70a) to the outer facial opening (70), exercise their action towards the convergent arrangement (75).

The convergent arrangement (75) includes rear connections (750, 751) through which said traction strips (741) remain under the influence of some stretching strips (754, 755).

At least, the stretching strips (754, 755) are elastic and are usually stretched in a way that they exert constant stretching force over said traction strips (741).

In both embodiments described, the links can include different elements that are suitable for the desired effect, such as free or rail passage openings (76), buckles with or without locks, Tancas (holdings for cords or tapes also known by the English expression ^" cord lock ^" ), flexible members with a fixation end and provided with eyelets, etc.

In another embodiment, the traction arrangement (74) and the convergent arrangement (75) are formed by elastic wall members that, as of links or linepull connections (740) in the outer surrounding area (70a) to the facial opening (50), define some branches of linepull or elastic traction limbs (743) that converge in a rear convergent arrangement (75). There is also a possibility that the different elements form part of a same piece that forms them.

On the other hand, in the inner hood (5), it has been foreseen that the inner facial opening (50) has a hermetic structure (53) that gives it a proper tightness.

The hermetic structure (53) - which peripheral union edge (53c) is linked to the inner union (52) of the hood (5) - includes a frame (53) of a deformable and non-slip plastic material that, under pressure, is capable of immovably fix to the user face. In an embodiment, said hermetic structure (53) includes a neoprene frame.

In other embodiments, the hermetic structure (53) can include a frame comprising, for example, an inner frame or facial juxtaposition part (53 a), a frame or outer part (53d) and an intermediate filling (53b).

The inner frame or face juxtaposition part (53 a) includes a deformable and non- slip plastic material that, under pressure, is capable of immovably fix to the user face. It has been foreseen that this inner frame be structured in suitable materials for its function, such as the polyether. Outside this inner frame or juxtaposition part (53a) the intermediate elastic deformable filling (53b) and the outer frame or part (53d) that covers the front part (11) are arranged. The mentioned elastic filling (53b) has the capacity of maintaining the hermetic structure (53) usually expanded.

The hermetic structure (53) is related, on the one hand, to the outer facial opening

(70) of the outer headpiece cover (7) and, on the other hand, to the inner facial opening (50) of the inner hood (5) belonging to the wall structure (2) of the suit (1).

This suit (1) has a structure of insulating walls (2) that forms both the body and the headpiece part, as well as the trouser legs (15) and the arms. These insulating walls (2) include aluminized (20c) alveolar walls (20) with thermal insulation and buoyancy capacity. For the purpose of present description, micro-alveolar walls (20b) shall mean those walls which alveoli are smaller than 20 mm. With the same purpose, macro- alveolar walls (20a) shall be those walls which alveoli are equal or bigger than 20 mm. It is clear that this is a matter of reference definition with the purpose of differentiating the alveolar walls (20) according to the smaller or bigger size of their alveoli.

This is important, among other things, due to the fact that it allows that the structure insulating walls (2) defines a sectorial differential insulation. This can be determined both by the size of the alveolar cells, as well as by the amount of walls and/or composition of these walls (2).

The possibility of a sectional differential insulation including, for example, micro- alveolar walls (20b) with alveoli smaller than 20 mm, in the limb areas, of the front protrusion (3) and the headpiece part, have been foreseen. Instead, the presence of macro-alveolar walls (20a), with alveoli equal or bigger than 20 mm, can be used in the rest of the suit (1).

Furthermore, it has been foreseen that the structure of insulating walls (2) includes, at least, en outer wall (21) that can be of materials such as a polyether and that, mainly, acts as a barrier against water.

On the other hand, the optional presence of an inner wall (22) in contact with the user body has been foreseen.

Also, it has been foreseen that the structure of insulating walls (2) defines a sectorial differential functionality, including micro-alveolar walls (20b) in areas that require more mobility that others, where macro-alveolar walls (20a) can be placed.

On the other hand, the structure of insulating walls (2) allows the incorporation of joint folds (8) such as leg folds (80), sleeve folds (81) and lower trunk folds (82). In an embodiment, these joint folds (8) are formed through a juncture (8b) between the juncture edges (8a). In another embodiment, a juncture interchangeable insert (8c) is incorporated which is placed between the juncture edges (8a).

Finally, it has been foreseen that, at least, the outer body cover (6) is provided with drainage passages (100) that prevent the accumulation of water in its outer cavity (61).

Undoubtedly, upon putting the present invention into practice, modifications may be introduced regarding certain construction details and form, without leaving the essential principles that are clearly explained in the claims below.
