Definitions

  • the invention relates to a floating hose reel of the marking line type comprising a plurality of elementary floats.
  • markup lines are frequently used, made up of a rope connecting a number of floats. These lines are launched overboard to mark, for example, the location of an object. In periods of non-use, these lines take up considerable space. In addition, they cannot be properly coiled and, as a result, they are frequently tangled. We cannot therefore be sure that we can deploy them very quickly. These lines cannot therefore be used effectively to rescue a person who has fallen overboard.
  • the present invention aims to remedy these drawbacks.
  • the floating hose reel as characterized in the claims, solves the problem of coiling at least one line connecting a plurality of floats and storing this line as well as the floats in a very small volume compared to the length of the line and number of floats. It also solves the problem of obtaining rapid and certain deployment of a line connecting a plurality of floats, after the assembly formed by the line and the floats has been launched into the sea.
  • the device, object of the invention comprises a plurality of elementary floats each comprising at least one body of very low density, associated with at least one line support making it possible to wind a certain length of line.
  • These elementary floats can be fitted two by two, so as to form a compact assembly, leaving between them a minimum volume just sufficient to store said certain length of line.
  • the elementary line lengths wound on the line supports are connected to each other in such a way that, when the assembly is unwound, an almost continuous unrolled line is obtained capable of floating under the effect of Archimedes' push which is exerted on the said bodies of low density.
  • Each elementary line length is permanently fixed, preferably at one of its ends, at at least one point of the elementary float with which it is associated.
  • the elementary line lengths wound on the line supports can be the adjacent segments of the same continuous line, without knots.
  • the elementary floats are held contiguous, in the interlocking position, by means which withstand only very low traction.
  • the reel When, the elementary floats being still assembled, the reel is launched into the sea, the elementary floats separate and the line which connects them is deployed.
  • a line permanently attached to floats arranged in series on this line can be coiled in a correct manner, and the assembly constitutes by 1 a line and the floats occupies only a very small volume compared to the length of the line and the number of these floats.
  • the line placed on the various line supports cannot become tangled and, moreover, it is protected from outside agents. Therefore, the line can be deployed with certainty, and with great speed.
  • the separation of the elementary floats and the deployment of the line require no human intervention after the launching of the reel at sea.
  • the implementation is easy, and this device is particularly suitable for deploying a lifeline very quickly making it possible to rescue a person who has fallen overboard.
  • This reel can comprise end floats comprising lashing means making it possible to fix it on any support, and for example on a lifebuoy.
  • the user can choose between several methods of winding the line on the line supports, and to a certain extent, he can also choose the distances to separate the floats when the line is deployed.
  • the floats may include reflective or light devices.
  • each element or detail having a defined function is identified by a number sometimes followed by a lowercase letter indicating the position of this element or this detail in the assembly formed by the nestable elements assembled.
  • the form given to each of these elements or details may not be exactly the same in the various embodiments.
  • the elementary floats (1) form a series (1 a, 1 b, 1 c ... etc) when they are nested in pairs. They are floating, however one at at least one of them may not be floating, the other floats (1) in this case ensuring the buoyancy of the assembly.
  • Each float comprises at least one low density float volume (2) and at least one line support, for example a coil (3).
  • the float volumes and the line supports can be separable or non-separable; they can also be geometrically confused.
  • the line supports, separable from the float volumes (2) with which they are associated and to which they remain connected by a certain length of line, can be floating or non-floating.
  • the elementary floats described in the following examples all have the symmetry of revolution and interlock coaxially with one another, but these conditions are not imperative.
  • the line is fixed to each elementary float, for example by means of a knot formed by two half-keys.
  • the line can therefore be continuous and, in this case, the breaking strength of the deployed assembly is not less than that of the line itself. It can, for example, pass through each elementary float passing through one or more holes or channels, so that it cannot, in any case, escape. Assembly means which are only resistant to low traction ensure the cohesion of the nested elementary floats.
  • the lengths of line coiled on the line supports are not apparent when the elementary floats are assembled and the reel is in the form of a compact volume whose general shape can be, for example, cylindrical, frustoconical, prismatic, etc. At least one of the ends of the line appears outside this volume.
  • FIG. 1 shows a reel comprising four elementary floats or three identical floats (1 a) (1 b) (1 c) and an end float (1 t).
  • Identical floats (1) in undetermined number, could thus be fitted.
  • each float consists of a float volume (2) of annular shape and of a frustoconical and hollow coil body (3) coaxially associated.
  • the extension of the internal wall of the coil (3) constitutes the wall of the conical hole passing through the float volume (2).
  • the elementary floats are fitted coaxially so that each coil belonging to an elementary float is housed in the internal space of the coil of the next float.
  • the terminal float (1 t) has a groove (4). bounded by volume annular (2 t), the coil (3 t) and a collar (5 t). Each coil has, at its end of smallest radius, a collar (5) and, near the float volume (2), a collar (6).
  • a groove (7) in which the line can be knotted by two half-keys, is delimited by the external wall of the coil, the float volume (2) and the flange (6).
  • Each coil is traversed by a hole (8) located near the end of the smallest radius, and by a hole (9) located in the groove (7).
  • the float volume (2) is crossed by a channel (10) opening on the one hand to the interior space with the annular volume and to the coil, and on the other hand to the space exterior to the coil in the groove ( 7).
  • the flange (6) is itself crossed by a hole (11).
  • Each of the identical coils could comprise, at its end of smallest radius, a low density volume crossed by a channel opening on the one hand to the space inside the coil, and on the other hand, by the hole ( 8), on the space outside this coil.
  • the line can be passed through these various holes or channels, according to one or other of the possible winding methods.
  • the low density volumes (2) have protrusions (12) and recesses (13) arranged in such a way that the protrusions (12) of a float volume (2) fit into the recesses (13) of the volume (2) following, when the elementary floats (1) are assembled.
  • These cohesion means must only withstand a small pull, and allow the separation of the elementary floats when a reel launched into the sea floats on the surface of the water.
  • These cohesion means can be such that the force necessary to separate the assembled floats is not identical for all the floats taken two by two. It is thus possible to promote a successive separation of the various elementary floats.
  • the walls of the coils are very thin and made of a resistant material, and the float volumes (2) can contain a material of very low density.
  • the float volumes (2) can be ballasted at a point close to the peripheral wall.
  • Each coil (3) could be ballasted at its end in order to cause the immersion of this end and to promote the unwinding of the line.
  • a wide variety of shapes can be given to low density volumes (2), for the same distance (D) separating the coils and the same conicity of these coils.
  • each coil can carry one or more layers of contiguous turns.
  • it reaches the groove (7 a) of the float (1 a) through the channel (10) or through the hole (9 a). It is knotted, for example by two half-keys, in the groove (7 a), then it leaves this groove by a notch made in the flange (6 a) or by the hole (11 a) passing through this flange. It is wound on the spool (3 a) up to the end collar (5 a). It is then passed through the hole (8 b) of the coil (3 b). The float (1 b) can therefore be fitted onto the float (1 a).
  • the line directly joins the groove (7 b) of the float (1 b), it is knotted in this groove, then is wound on the spool (3 b) up to the end collar (5 b) covering the length of taut line between this collar (5 b) and the groove (7 b). Winding continues in the same way on the following coils. Finally, the line reaches the groove (4) of the terminal float (1 t) passing, in this example, through the hole (8 t) passing through the coil (3 t). It is knotted, then wound in the groove (4), which is covered by a protective ring (14). The free strand passes between the edge of this ring and the edge of the collar (5 t).
  • each coil can carry an even number of layers of turns, the line being knotted near the end collar (5) of each coil. It is also possible to form the nodes on the successive reels, alternately at the end of a reel and in the groove (7) of the next reel. In this case, by having only one layer of turns, the diameter of the line can be almost equal to the distance (D) separating the coils.
  • the floats When the line is deployed, the floats can be equidistant or not depending on whether or not the same winding method was used on the different elementary floats. To promote the separation of the floats, one of the end floats can be non-floating, the buoyancy of the assembly being ensured by the other floats. The submerged float effectively opposes the drift of other floats under the effect of the wind.
  • FIG. 2 of plate 2 schematically and partially represents two identical elementary floats fitted together. Each of them has a low density volume (2), and a coil (3) separable from the volume (2).
  • Each coil (3) comprises a low density volume (16) allowing it to float alone. Its larger radius end carries a collar (17) which can fit into the central hole of the float volume (2). A weak pull is enough to separate each coil (3) from the float volume (2) with which it is associated. A groove (7) is included between this collar (17) and a collar (6) through which a hole (11) passes.
  • the low density volume (16) can be traversed by a channel (18).
  • each coil (3) can move away from the float volume (2) with which it was associated up to a distance at most equal to the length of line previously wound in the groove (15).
  • the next float volume (2) can move away from the previous coil up to a distance at most equal to the line length carried by this coil.
  • the coils (3) can be non-floating, in order to cause the immersion of the line between the float volumes (2).
  • FIG. 3 of Plate 2 represents a first elementary float (1 a) comprising a low density annular volume (2), a frustoconical coil (3) floating, and a second coil (19) arranged coaxially in the interior space to the coil (3).
  • This first float (1 a) is placed on a support (20), and the small coil (19) makes it possible to store a certain length of line connecting the element (1 a) to the support (20) and therefore allowing it to move away from this support.
  • a support can be made integral, for example, with a boat, an inflatable raft or a buoy.
  • Figure 4 of Plate 3 is a partial representation of a reel whose elementary floats are not identical.
  • the frustoconical coils (3) are of unequal length, but they have the same angle at the top, and the same distance (D) is kept between all the coils taken two by two.
  • the element (2 a) of the first float (1 a) has a deep groove (15) and rings (21) through which a strap (22) can be passed in order to fix this element on a life buoy, for example .
  • the coil (3 a) is separable from the volume (2 a) and has a low density volume (16) allowing it to float alone, and a channel (23) whose two ends open in a circular groove (24) close to the large base of this coil.
  • the terminal float (1 t) has two low density volumes, the annular volume (2 t) and the volume (25), the latter being housed in the hollow end of the coil (3 a).
  • One end of the line can be fixed directly to the strap (22).
  • the line reaches the groove (15) passing through a channel (10), it is knotted then wound in this groove, then it passes through the channel (23) of the coil (3 a) and it is knotted in the groove (24) before being wound on the coil (3 a). It then joins the external face of the coil (3 b) through the hole (8 b) or the hole (9 b) depending on the winding method chosen.
  • the winding continues according to one or other of the possible methods.
  • the reel (3 a) can move away from the element (2 a) up to a distance at most equal to the length of line stored in the groove (15) of this element. Compared to the total length of the line and the number of floats, the volume of this reel is very limited. This reel is particularly suitable for forming a rescue line connected to a lifebuoy.
  • FIG. 5 of Plate 4 represents an alternative embodiment of a first elementary float (1 a) which can be placed on a socket (26), which can itself be fixed by a strap (22) on a lifebuoy.
  • the coil (3 a) is integral with the volume (2 a). This comprises a groove (27) opening on the face to be applied to the fixing sleeve (26) and on this same face, a groove (28) in which the edge of the sleeve (26) can s' follow suit.
  • the spray (27) communicates with the groove (24) located at the base of the coil (3a) by a channel (23).
  • the coil (3 a) has a low density volume (16) contributing to the buoyancy of this first float.
  • the line is passed through the channel (23) and knotted in the groove (24) and in the groove (27) in which it is wound.
  • the free strand passes through a ring (21) integral with the socket, and leaves the socket through a hole (29).
  • the line appearing outside the groove (24) is coiled on the spool.
  • the float (1 a) can move away from the sleeve (26) and the buoy up to a distance at most equal to the length of line stored in the groove (27).
  • FIG. 6 of Plate 4 shows two identical elementary floats whose low density volumes and line supports are geometrically combined.
  • Each elementary float has the shape of a cone comprising two walls having the same angle at the top.
  • a low density volume (2) is delimited by these two walls.
  • a coil (3) therefore constitutes in itself an elementary float (1).
  • Each float has an end collar (5) and a collar (6).
  • the collar (6) of an elementary float is applied to the internal wall of the next conical float, near the large base of this float.
  • the collar (5) fits into a ring secured to the internal wall of the next float.
  • the line is wound on the conical surface located between the collar (5) and the collar (6). It can be knotted in a circular groove (24) close to the collar (6). It can pass through each float through the holes (8) or (9). In addition, it can be arranged in a longitudinal groove (30), between the collar (5) and the groove (24). Several winding methods are possible.
  • This reel can be composed by an unspecified number of elementary floats. It is suitable, for example, to drop a load from an aircraft, the floats separated during the fall into the atmosphere braking the speed of the fall. It is also suitable for forming a floating anchor allowing to oppose the drift of a boat a variable resistance according to the number of floats assembled.
  • Figure 7 of Plate 5 partially shows three assembled elementary floats.
  • a low density volume (2) of approximately cylindrical shape and comprising a deep groove (15) alone constitutes an elementary float.
  • the groove (15) communicates with one of the faces perpendicular to the axis through a large annular opening. It communicates with the other face by a channel (10) and by a longitudinal groove open on the peripheral wall, this groove allowing a winding method according to which the line does not cross the floats.
  • Annular protrusions (12) and grooves (13) allow these elementary floats to be coaxially assembled. They each have a coaxial hole (31) for fixing the flagstaff.
  • the line is knotted in the groove (15) and wound in this groove. It joins the groove (15) of a next float, passing either through a channel (10) or through an external groove.
  • Each elementary float could be inflatable. This reel is suitable, for example, for building buoys stackable during periods of non-use.
  • Figure 8 of Plate 5 shows three elementary floats fitted together. Each of them consists of a low density volume (2) integral with the end of the smallest radius of a frustoconical coil (3), which comprises at its end of largest radius a collar (5).
  • the relative dimensions of the various floats are such that they can be nested coaxially one inside the other, the collars (5) then being, approximately in the same plane.
  • These collars (5) are ballasted so that each coil is immersed.
  • the coils have the same angle at the top and the distance (D) separating two successive coils is large enough that it is possible to wind several layers of turns on each of them.
  • the line crosses each coil through the holes (8) or (9) and is knotted near the float volume (2).
  • the relative buoyancy of the various elementary floats is such that the floats contained remain inside the floats which contain them when the assembly floats on the surface of the water.
  • This reel can be used for various underwater work.
  • the end of the line appearing inside the smallest coil (3 a) can be connected to a ballast causing the immersion of one or more elementary floats (1), the largest float remaining on the surface .
  • Submerged floats can indicate depth levels, for example, decompression levels for divers.
  • Figure 9 of Plate 6 is a partial representation of five elementary floats nested coaxially. Each of them is made up of a low density volume (2) having roughly the shape of a cylinder of low height compared to the radius, and of a cylindrical coil (3). Each coil enters the immediately larger diameter coil, the end of the contained coil applying to the float volume (2) associated with the containing coil. The float volumes (2) associated with two successive nested coils are therefore separated by these two coils, the volumes (2) of odd order being in contact with one another and likewise the volumes (2) of even order . Two successive coils are separated by a distance (D) sufficient to store a certain length of line. This crosses the wall of each coil by a hole (8) or (9) and is knotted on each of them.
  • D distance
  • each elementary float (1) has a particular equilibrium, so that each time a float separates from the floats which it contained and which are still assembled, movements of rotation or rocking of the assembled floats can favor the separation of the float following.
  • the float volumes (2) are ballasted at certain points, the relative arrangement of these ballasts making it possible to obtain this result.
  • the cohesion means allow only one relative position of the elementary floats. This reel being launched into the sea, the elementary floats (1) can move away from each other in different directions, remaining connected by the same line, and form an easily identifiable grouping.
  • a reel can have a float volume associated with several coils on each of which a series of nestable floats can be placed.
  • a reel can also be composed of an indefinite number of identical elementary floats, each comprising two coaxial coils of different diameters, each of them being integral with one of the planar faces of a cylindrical float volume. The smallest coil of an elementary float fits into the largest coil of the next element, sufficient space being reserved for the line between these two coils.
  • This reel can be made, for example, of plastic.
  • the float volumes can be hollow or contain a very light material. They could contain reflective or luminous devices, their walls possibly being transparent. They could also be made of cork, or even constituted by an inflatable envelope.
  • the floating reel, object of the invention can be used to store at least one line connecting a plurality of floats.
  • the line, rapidly deployed, constitutes a markup line.
  • the applications are varied: rescue at sea, safety of swimmers, marking of fishing gear, scuba diving, maritime work, floating anchor, release of a load by aircraft ... etc.
