  • Patent number: 10797372
    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.

  • Patent number: 9478845
    Abstract: An arrangement for mounting a directional antenna (10) in an adjustable inclined position to an approximately vertical supporting member (11) comprises a separate upper antenna bracket (12) and a separate lower antenna bracket (12). The two antenna brackets (12) are formed equal to each other and each comprises a first mounting member (13), intended to be mounted to the antenna (10), and a second mounting member (14), intended to be mounted to the supporting member (11). The two mounting members (13, 14) are connected to each other by an intermediate connection (15, 16) which is arranged to permit the two mounting members (13, 14) to be moved a limited distance in an approximately horizontal direction towards or away from each other and to become fixed in adjusted positions relatively to each other.

  • Patent number: 5595378
    Abstract: A clamping jaw (10) for a clamping device, adapted to be mounted on a profile member (31) is formed by two separate jaw members (11) and a common rear counter support (12) for said members, which is arranged to transmit clamping forces produced by means of clamping bolts (32) to the two jaw members (11). The jaw members (11) and the counter support (12) have cooperating engagement means (13, 15) for placing and holding the jaw members (11) in predetermined positions in relation to the counter support (12). In order to make it possible to adapt the clamping jaw (10) to profile members of different shape and size, the engagement means (13, 15) are arranged to permit each jaw member (11) to be placed and held in a plurality of different positions in relation to the counter support (12).
