Abstract

Chain clamp and method for clamping around an elongated object and for serving as a support for separate objects. The chain clamp includes a plurality of links with a first link and a second link, and with each link having two attachment portions, a connection member connecting links, and a tensioner adapted to connect to the first and second link and to force the links towards each other to tension the chain clamp and clamp it around the elongated object. At least one link is a piece cut from an elongated extrusion and has a fixed cross-sectional profile and a longitudinal direction, wherein each of the two attachment portions of the at least one link are defined by a respective portion of the cross sectional profile and its continuation along the longitudinal direction of the at least one link.

Dependent claims

Chain clamp for clamping around an elongated object, and for serving as a support for separate objects, wherein the chain clamp comprises:

a plurality of links, the plurality of links comprising at least a first link and a second link, each of the first and second links having two attachment portions, one of the two attachment portions at one end of each respective link of the first and second links and another of the two attachment portions at an opposite end of the respective link of the first and second links,
at least one connection member, connecting two links from among the plurality of links at respective attachment portions,
a tensioner, adapted to connect to the first and second links and to force the first and second links towards each other to tension the chain clamp, characterised in that at least one of the plurality of links is a piece cut from an elongated extrusion and has a fixed cross-sectional profile and a longitudinal direction, wherein each of the two attachment portions of the at least one of the plurality of links are defined by a respective portion of the fixed cross-sectional profile of the at least one of the plurality of links.
