ABSTRACT:
BACKGROUND
This invention relates to filament connectors, and is applicable, particularly but not exclusively, to filament connectors to be used on monofilament plastics lines, such as fishing lines. The expression “filament” used herein includes cords, ropes, straps, steel wires and monofilament plastics lines, nylon spider wire and any other form of fishing line or other constraining material.
OBJECT OF THE INVENTION
Commonly, such filaments are connected together or to other objects by the use of knots. However, it has been found that knots have the effect of reducing the breaking load of the filament by up to 50%. This is highly undesirable, since the breaking load is often a crucial parameter of a filament.
STATEMENT OF THE INVENTION
According to one aspect of the present invention there is provided a filament connector including a body provided with an internal cavity, the cavity being open to the exterior of the body through an aperture, the interior of the cavity defining a pair of cavity walls converging towards said aperture, a wedge member positioned within said cavity and having a pair of part surfaces each facing a different one of said cavity walls, the wedge member having a degree of freedom of movement towards and away from the aperture, whereby a filament can be formed into a bight inside the cavity, the bight passing around that part of the wedge member remote from the aperture and between at least one of said cavity walls and the adjacent part surface of the wedge member, so that tension in the filament outside the connector pulls the wedge member toward the aperture and compresses the filament between the cavity wall and the adjacent part surface of the wedge member.
Preferably the part surface and adjacent cavity wall are parallel and may be flat.
Advantageously, both of the part surfaces are parallel to the adjacent cavity walls and are flat.
Conveniently the surface of the wedge member joining the two part surfaces and remote from the aperture is smoothly curved and preferably tangential to said part surfaces.
Preferably the body is provided with an openable lid to expose the cavity, when open, the body or the lid carrying the wedge member by a connection which is flexible, frangible or which has limited sliding movement towards the aperture, the wedge member being located, such that when the lid is closed, the wedge member is positioned within said bight.
Advantageously the lid is held closed by clip means.
Conveniently the body is provided with two or more of said cavities, apertures and wedge members, whereby bights of different filaments may be fastened to the body and thereby to each other.
According to another aspect of the present invention there is provided a filament connector, as described above, adapted to be fastened to a monofilament fishing line.
Conveniently the body, at a position remote from the aperture, is adapted to locate and retain an element of a fishing component, such as an eye of a fishing hook or of a swivel.
