Abstract
A device which can slide up and down on a chain or cable, can be loosened to attach to the chain or cable, but does not have any parts that come free when the part is loosened. The device includes first and second pieces, each made of structural material, the first and second pieces fitting together at concave and convex surfaces, to form an interlock forms inner surfaces with a through hole of a first shape that can slide along either a cable or a chain.
Claims7
A cable sliding device, comprising:
- first and second pieces, each made of structural material,
- said first piece and said second piece having the same shape, and each having a first end and a second end,
- said first and second pieces fitting together at an inner surface location, where a first surface of said first piece presses against a second surface of said second piece, and where said first end of said first piece presses against said second end of said second piece,
- said inner surface location shaped to interlock the first and second pieces together, and
- where an area of the inner surface location forms inner surfaces forming a plus-shaped area, having a first linearly extending surface shaped to hold a chain link facing in a first orientation, and a second linearly extending surface, orthogonal to said first linearly extending surface, and shaped to a different chain link facing in a second orientation orthogonal to the first orientation,
- said first end of said first piece and said second end of said second piece forming a first end portion where said first and second pieces come together forming a first hole that extends through both of said first and second pieces,
- said second end of said first piece and said first end of said second piece forming a second end portion, at an opposite end to said first end portion, where said first and second pieces come together and forming a second hole that extends through both of said first and second pieces.

A cable sliding device, comprising:
- first and second pieces, each made of structural material,
- said first piece and said second piece having identical shapes, and each having a first end and a second end,
- said first and second pieces fitting together at an inner surface location, where a first surface of said first piece presses against a second surface of said second piece, and where said first end of said first piece presses against said second end of said second piece,
- said inner surface location shaped to interlock the first and second pieces together, and
- where an area of the inner surface location forms inner surfaces forming a through hole of a first shape,
- said first end of said first piece and said second end of said second piece forming a first end portion where said first and second pieces come together forming a first hole that extends through both of said first and second pieces, said second end of said first piece and said first end of said second piece forming a second end portion, at an opposite end to said first end portion, where said first and second pieces come together and forming a second hole that extends through both of said first and second pieces,
- where said inner surface location which interlocks the first and second pieces together has multiple curved portions therein which press against each other when interlocked leaving no spaces therebetween other than the space of the inner surfaces forming the through hole, and where identically shaped multiple curved portions are on both said first piece and said second piece.
