Definitions
- the present invention relates to the field of marine, and more particularly to a rope cutter that can be mounted on a boat propeller shaft.
- a rope cutter is useful for releasing the propeller shaft when a rope is caught in the shaft and may block the rotation of the propeller.
- rope used here covers a large number of objects likely to be caught around the tree, including, ropes, orins, cables nets or parts of fishing nets, or herbs, such wire cutter is disclosed in FR2768120.
- the object of the invention is to provide a cable cutter which has improved mounting facilities and which can meet the problem posed by the propeller shafts mounted on an intermediate chair.
- such a rope cutter comprising a hub for fixing on a propeller shaft of a boat and a blade carried by said hub, said rope cutter having several parts removable between them so that the shaft of propeller can be introduced radially into the hub.
- the several parts are two parts that can be disassembled and assembled along an axial plane of the hub. They are advantageously designed to be held by at least one screw arranged so that a first part comprises a housing for supporting the head of said screw and the second portion comprises a threaded zone for engaging said screw.
- the several parts are two parts that can be disassembled and assembled in two separation planes arranged on either side of an inner bore of the hub, and defining between them an opening at least as wide as the diameter of said bore.
- the planes may be substantially symmetrical relative to an axial plane of the hub. In addition they can also be parallel to each other and possibly tangent to the bore.
- the parts may be provided to be held by at least one screw, a first part comprising, facing each other, on either side of the opening, on the one hand a housing for the support of the head of said screw and secondly a threaded zone for engaging said screw, the second part comprising a non-threaded bore for the passage of said screw between the separation planes.
- the wire cutter advantageously comprises a locking screw screwed into a minus one parts, the locking screw being provided to exert a locking force against the shaft.
- FIG. 1 is a perspective view of a first embodiment for a rope cutter according to the invention, mounted on a propeller shaft;
- FIG. 2 is an exploded perspective view of the cable cutter of FIG. 1;
- FIG. 3 is an exploded plan view of a second embodiment for a cable cutter according to the invention.
- FIG. 4 is a schematic view of a part of a boat comprising a shaft mounted on an intermediate chair and equipped with two cutters according to the first embodiment, illustrated in Figures 1 and 2.
- the cutter comprises two openings 14 for receiving the screws 13, pierced in the hub 2, on either side of the bore 5.
- Each piercing 14 is perpendicular to the plane P. It comprises a first wide zone 141, for receiving the head of the screw 13, a second zone 142 of reduced diameter extends the first to pass the body of the screw. The first zone opens at the periphery of the hub. The second zone of work in the plane P. The first and the second zone are not threaded.
- a third zone 143, threaded to engage with the screw 13, extends the second zone through the second portion 12.
- a locking screw 15 is also provided. Its purpose is to avoid the relative movement of the shaft and the rope cutter. It is screwed into a thread 16 passing through the hub 2 between its periphery and the bore 5, in the second part 12.
- FIG. 3 A second embodiment will now be described for a cable cutter according to the invention, with reference to FIG. 3. This embodiment will only be described in that it differs from the embodiment previously described with reference to FIGS. Figures 1 and 2. Similar elements will be assigned the same references.
- the cable cutter comprises two parts 21,22, not symmetrical to each other. It comprises a first portion 21 having a shape of "C", and a second complementary portion 22.
- the branches of C are defined by two planes R parallel to each other and extending tangentially to the bore 5.
- a first portion substantially semi -cylindrique of the bore 5 is carried by the first portion, and a second complementary portion is carried by the second portion 22.
- the distance between the parallel planes R is substantially equal to or greater than the diameter Dl of the shaft.
- a portion of the hub bore 5 carried by the first part 21 thus comprises an opening of width substantially equal to the diameter D1 of the shaft, this opening extending between the planes R.
- the shaft can be introduced transversely inside the first part 21 in the form of "C", then the second complementary part, comes to reform the cutter in its entirety. This can be done without the need to remove the propeller, as for the embodiment of Figures 1 and 2.
- a screw 13 allows the assembly and maintenance, between them, parts 21,22.
- a piercing 14 is provided in the hub 2 to receive the screw 13.
- the piercing 14 is perpendicular to the planes R. It comprises, at a end of a branch of "C", a first wide zone 141, for receiving the head of the screw 13 and a second zone 142 of reduced diameter which extends the first to allow the body of the screw to pass.
- the first zone opens at the periphery of the hub.
- the first and second zones are not threaded.
- a third zone 144, threaded to engage with the screw 13, is pierced opposite the second zone through the other branch of the "C" shape.
- the third zone extends between the plane R and the periphery of the hub, respectively of the other branch.
- a fourth zone 145 is drilled further through the second portion 22, for the adjusted passage of the body of the screw 13, and holding in place this second portion relative to the first
- FIG. 4 illustrates a part of a boat 30, in the vicinity of a propeller 31 of the boat 30.
- the boat has a hull 32.
- a propeller shaft 1 leaves the hull 32 through a sternum 33, and carries the propeller 31 at an end remote from the sternstand 33.
- a chair 34 Given the outer length of the shaft 1, a chair 34 provides support for the shaft between the stern and the propeller, a first region 36 of the shaft 10 extending between the sternum and the chair, and a second region 37 extending beyond the chair, to the propeller.
- a first wire cutter 10 is mounted in the first region 36, in the vicinity of the sternstand.
- a second cutter 10 is mounted in the second region 37.
- the planes can be replaced also by other complementary forms, including for example redents for the mutual interlocking of the parts of the cutter.
