A DEVICE FOR WINDING UP A LINE AROUND THE CIRCUMFERENCE OF A LIFE-BUOY

Abstract: The device for winding up the line (S) around the circumference of life-buoys (SV) consists of means (1) for keeping said line (S), obtained in said structure of said life-buoys (SV), or in continuous means (2) or in section means, that may be applied along said circumference.

Description: "A DEVICE FOR WINDING UP A LINE AROUND THE CIRCUMFERENCE OF A LIFE-BUOY" The present invention concerns a device for widing up the line around the circumference of life-buoys. It is well known that the life-buoys provided along the broadsides of ships or other floating means must have, according to international rules, a line of a predetemined length, one end thereof being fixed to the life-buoy and the other one to be linked to the ship, so as to allow to recuperate the life-buoy and the eventual shipwrecked person to whom said life-buoy has been thrown. Usually, said line is collected in a hank which sometimes is difficult to unravel, as it might also be hardened by an eventual coat of paint, whereby the original intention of the law is no longer observed. It is the aim of the present invention to completely solve above mentioned inconveniences in an easy and functional manner. The aim set forth is reached, according to the present invention, by means of a device for winding up the line around the circumference of the life-buoys, consisting of means for holding the line obtained in the structure of said life-buoys, or by continuous or section means that may be applied along said circumference in such a way, that the unwinding of the line, in case of need, takes place together with the throwing of the life-buoy. The main advantage of the device according to the present invention consists in the reduction of the encumbrance of the wound line, as well as the convenience of its functioning. The device according to the present invention will be described more in detail hereinbelow, relating to the enclosed drawings in which some preferred embodiments are shown. Figure 1, shows a front and partially transparency view of a device for winding the line around the circumference of a life-buoy. Figure 2, shows a vertical section of a variant according to figure 1. Figure 3, shows a vertical section of a variant of the device according to the present invention, comprising a means for winding up the line applied externally to the structure of the life-buoy SV. The enclosed figures show a device for winding up a line S around the circumference of a life-buoy SV, mainly consisting of an anular groove 1 provided in the thickness of said life-buoy SV and in a decentralized position, so as to avoid any interference with the supports 3 of the perimetral line sections 4 that receive said line S in a plurality of overlaying windings. It is obvious that the hollow volume of said anular groove 1 determines a loss of hydrostatic push which, even if very small, will be balanced - according to the present invention - by a small increase of the dimensions of the whole tore. The variant of above described device requests therefore a new kind of realization of life-buoys; but the device according to the present invention may also be applied to already existing life-buoys. For this purpose, a further variant has been shown in figure 3 and provides the application, along the median circumference of the life-buoy SV, of a circular supporting guide 2 that forms, together with the structure of said life-buoy SV, the anular housing 5 for receiving a plurality of windings of the line S. Furthermore, it is not indispensible that said housing 5 consists of a complete circular guide, but may consist of a plurality of separate, non continuous sections, by means of which the winding of the line S is obtained according to the aim set forth.

Claims: CLAIMS 1. A device for winding up the line around the circumference of the life-buoys (SV), characterized in an anular groove (1) provided in the thickness of said life-buoy (SV) in a decentralized position for avoiding any interference with the supports (3) of the sections of the perimetral line (4) that receive said line (S) in a plurality of overlaying windings. 2. A device according to claim 1, characterized in a life-buoy (SV) of an increased volume for balancing the loss of hydrostatic push due to the volume of said groove (1). 3. A device according to claim 1, characterized in the application, along the median circumference of already existing life-buoys, of a circular supporting guide (2) that forms, together with the whole structure, the anular housing (5) for receiving a plurality of windings of said line (S). 4. A device according to claims 1 to 3, characterized in the presence of a plurality of separate, non continuous sections of said anular guide applied along the circumference of already existing life-buoys.
