Patent number: 5624220Abstract: 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.Type: GrantFiled: September 15, 1995Date of Patent: April 29, 1997Assignee: Hitti AktiengesellschaftInventors: Rupert Janssen, Markus Frowis, Luc Guillon

Patent number: 5611474Abstract: Attachment members (28) are used for securing insulation panels (30) to structural components (31). Each attachment member (28) includes a nail (29) which is driven by a setting tool into the structural component. A connecting region (26a) on a guide tube (25) of the setting tool generates a frictional force with a counter-connecting region of a hollow shaft (28b) in the attachment member when the nail (29 is driven. Via the generated frictional force, it is possible to check if the attachment member is properly connected after the setting tool drives the nail. The frictional force between the guide tube (25) and the inside surface of the hollow shaft is greater than the frictional force between the hollow shaft (28b) and the insulation panel (30).Type: GrantFiled: May 18, 1995Date of Patent: March 18, 1997Assignee: Hilti AktiengesellschaftInventors: Josef Schmidle, Dimitrios Stefanoudakis
