HRP20100449T1 - Lifeboat - Google Patents

Abstract

A lifeboat (1), which is intended to be used in vessels (12) or other constructions used at sea and which comprises a hull part (2) and a cover part (3) fixedly attached thereto and being movable with respect to the hull part (2) to a first position for the storage of the lifeboat (1) and to a second position for the utilisation of the lifeboat (1). The height of the lifeboat (1), when the cover part (3) is in said first position, is substantially smaller than the height thereof, when the cover part (3) is in said second position. It is provided with support members (6), which are supported by the hull part (2) and the cover part (3) so as to keep the cover part (3) in said second position and which can be inserted at least partially inside the hull part (2) for the storage position of the cover part (3). It is further provided with power cylinders (7), e.g. gas springs, which are arranged to act on turnable lifting arm mechanisms (16, 17), which are supported by the hull part (2) and the cover part (3) for moving the cover part (3).

Claims (10)

1. A lifeboat (1), which is intended for use in other vessels (12) or structures at sea and which consists of a hull part (2) and a superstructure (3) which is attached to it and which moves relative to the hull part (2) to the first position so that the lifeboat (1) can be stored, or to the second position so that the lifeboat (1) can be used, whereby the weight of the lifeboat (1), when the superstructure ( 3) in the first position it is significantly smaller than when the superstructure (3) is in the second position, characterized by the fact that it comes with very vertical supports (6) on both sides and both ends of the lifeboat, which supports the hull part (2) and the superstructure ( 3) in order for the superstructure (3) to remain in the mentioned second position, and which can be inserted at least partially in the hull part (2) in order to enable the stowage position of the superstructure (3), and is additionally equipped with a certain number of mobile lifting mechanisms (16, 17) ) each of which comes with working cylinders (7), eg gas springs, etc is supported by the hull part (2) and the superstructure (3) in order to move the superstructure (3), and the superstructure (3) consists of a non-flexible roof (3a) and two separate folding parts (4), such as an accordion structure (4), made from solid parts that are attached to the roof and hull (2), and arranged on both sides of the lifeboat (1). 2. Lifeboat according to claim 1, characterized in that the lifting mechanisms (16, 17) and working cylinders (7) are placed on both sides and both ends of the lifeboat. 3. Rescue boat according to claim 1, characterized in that the hull part (2) and/or the superstructure (3) comes with a guidance mechanism (18), e.g. guides for guiding the arms of the lifting mechanisms (16, 17) and coordinating the work of mechanisms. 4. A lifeboat according to any of the aforementioned requirements characterized in that the folding structures (4) come with their own supports (6). 5. A lifeboat according to any of the aforementioned requirements, characterized in that the folding or flexible material forms the middle part (5) which has the function of an access road to the lifeboat, and is located between the accordion structures (4) in the longitudinal direction of the lifeboat. 6. A lifeboat according to any of the aforementioned requirements characterized by the fact that the structure of the hull part (2) corresponds to the trimaran type (9, 11, 10, 11, 9). 7. Lifeboat according to any of the preceding claims from 1 to 5, characterized in that the hull part (2) has a single hull structure. 8. A lifeboat according to any of the preceding claims, characterized in that it comes with suspension mechanisms (8) whereby it can be suspended from the control mechanism (14, 15), eg by a conventional hoist (crane) or a telescopic hoist. 9. A lifeboat in accordance with the aforementioned requirements, with a capacity of about 150 people. 10. A lifeboat according to any of the aforementioned requirements, characterized in that it comes with its own drive mechanism (20).
