  • Patent number: 5752681
    Abstract: A pipe and cable clamp is formed of a base part (5) and a receiving strap (6). To assure that a pipe or cable positioned in a receiving space between the clamp and a surface of a structural component is adequately retained, where the receiving strap forms two receiving spaces (8, 9) located laterally from the base part, a spring arm (7) is located in the receiving space (8) closer to the base part (5) in the event a pipe or cable of larger diameter is located in the receiving space more remote from the base part. The spring arm (7) extends outwardly from the base part (5) and projects in an unloaded state into the receiving space (8) closer to the base part (5).

  • Patent number: 5669589
    Abstract: A pipe and cable clamp is formed of a base part (1) and a generally arcuately shaped receiving strap (2) extending outwardly from the base part. A joint (3) is located in the receiving strap (2) spaced from the free end (2a) and the joint is shaped so that the free end region extending from the joint can be folded into a receiving space bounded by the receiving strap. As a result, pipes and cables of different diameters can be secured to the structural member, so that the free end region 2b is folding into receiving space when smaller diameter pipes and cables are clamped, and the free end region 2b is prevented from folding outwardly if larger diameter pipes are clamped, so that the free end region assists in securing the pipes and cable of larger diameter.

  • Patent number: 5624220
    Abstract: An attachment member arranged to be secured to a surface of a hard receiving material by an explosive powder charge operated setting tool is formed of a fastening element (1), such as a nail, and a prestressing element (2). The prestressing element assures a sound attachment by bridging differences in the depth to which the nail is driven. To increase its surface contacting the surface of the hard receiving material, the prestressing element is laterally enclosed at least in part by a plastics material part (3) so that the pressure of the attachment member in contact with the receiving material and the danger of tilting of the setting tool relative to the receiving material are reduced. Further, a recess (3b) is formed in the plastics material part (3) to improve guidance between the prestressing element (2) and a bolt guide (4) of the setting tool.
