Abstract

A FLOATING ANCHOR IS CONSTITUTED BY A TUBE-SHAPED BODY 1 HAVING AN ENTRY OPENING 4 IN THE FRONT AND AN EXIT OPENING AT THE REAR, AS WELL AS A PLURALITY OF PARTITIONS 3, 5, 6, 7 THAT DIVIDING THE INSIDE OF THE BODY PASSING FOR THE FLOW OF WATER AND WHICH EXTEND FORWARD, BEYOND THE ENTRY OPENING, UP TO A COMMON POINT 2 FOR A CABLE ATTACHMENT TOWING. THE PRESENCE OF THE PARTITIONS PREVENTS THE REAR PART OF THE ANCHOR FROM BEING BACK INTO THE ENTRY OPENING UNDER THE EFFECT OF CERTAIN WAVES. APPLICATIONS: EQUIPMENT FOR RESCUE RAFTS OR OTHER SIMILAR SMALL BOATS.

Description

The present invention relates to a floating anchor

  or anchor cone, especially for life rafts or

very small boats.

  It is necessary to use a floating anchor with a life raft to prevent it from drifting too far from the place of launching and

  thus facilitate its location by a possible rescuer.

  A floating anchor can also be used to stabilize a raft.

rescue water.

  The anchor cones or floating anchors which currently exist have the disadvantage that their rear end tends to engage in their entry under 1 '

effect of certain waves.

  Lines or nets have been provided on the cables that connect the anchor to the boat to counter this trend, but these are measures at the same time

expensive and ineffective.

  To remedy this drawback, the floating anchor

  te according to the invention comprises a plurality of flow channels separated from each other by one or more

  partitions formed from sheet material, this partition

  its (or these partitions) extending from the entrance of these

  channels to an attachment point for a towing cable.

  In a preferred embodiment, the floating anchor

  aunt according to the invention consists of a tube, one end of which has an inlet, while 1 '

  other end has an outlet, the interior

  tube laughter being divided by one or more partitions

  substantially longitudinal, which extend from the

  to a point of attachment for a hauling cable.

  Preferably, the partition divides the tube into a

  plurality of sectors arranged around a longitudinal axis

nal of the tube.

  In the case where the exit of a floating anchor se-

  lon the invention is pushed back into the entrance, the presence of the partitions has the effect that a single flow channel

  is obstructed, the (or each) remaining channel swelling ra-

  pidance of water, which tends to clear the obstructed part.

  The extension of the partitions upstream of the entrance prevents the latter from being completely obstructed by the area

anchor.

  The section of the entry is preferably larger than that of the exit. For example, in a preferred embodiment of the invention, the anchor is constituted by a frustoconical tube, the partitions dividing

the interior of the tube in sectors.

  As a variant, the tube can have another shape;

  it can have for example a square or rectangular section

  In addition, the partitions can extend significantly-

  until the exit, since we get

strengthening the anchor.

  In a particularly advanced form of execution

  tagger, four partitions and the number of compartments

  corresponding nals We thus obtain a balance between

  the reinforcement thus obtained and the cost of the additional materials

used.

  The edge of the inlet and those of the partitions can be provided with stiffening means, for example

metallic wires.

  In any case, the invention will be well understood at

  using the following description, with reference to the drawing

  schematic annexed, representing, by way of nonlimiting examples, several embodiments of this anchor:

  Fig 1 is a perspective view of a floating anchor

  aunt according to the invention; Fig 2 is a sectional view along A A of Fig. 1; Fig 3 is a side view of a second embodiment of this anchor;

  Fig 4 is an end view of the anchor of fig 3.

  The floating anchor shown in Figures 1 and 2

  consists of a frusto-conical tube 1 and four partitions

  radial tones 3, 5, 6, 7, which are sewn on the face

  internal of tube 1 Partitions 3, 5, 6 and 7 are assembled

  locked to each other along the longitudinal axis 8 of the anchor and extend beyond the tube, forward, to a common summit, where is provided a fastening means 2 for a towing cable The edge of the inlet opening 4 of the tube is optionally reinforced with a wire

  metallic or other rigid support (not shown).

  Figures 3 and 4 show another form of

  execution of the invention, in which the anchor is con-

  formed by a tube 9 of square section, which is closed at one end by a layer of sheet material 15

  provided with a hole 10 serving as an outlet port Four partitions

  sounds 11, 12, 13, 14 extend from this layer 15 to

  that at a common summit o is fixed an attachment means 16 for a towing cable (not shown)

  stiffening are provided on the edge of the opening of

  trée 17, as well as on the front edges 18 of the partitions.

  The floating anchors according to the invention can be

  be made of nylon, polyester or any other

fabric, waterproofed or not.
