  • Patent number: 6401423
    Abstract: A deflector track tab structure, and method of formation, for positioning studs along a deflector track. Starting with a sheet of metal such as steel, tongues are formed within the sheet such that the tongues are oriented along the length of the sheet. Slats are formed in each tongue, wherein the slats are oriented along the length of the tongue. The tongues are bent away from the sheet resulting in tabs integral with the sheet and normal to the sheet. A flange is formed from the sheet on each side of the sheet such that a track web between the flanges remains. The flanges are normal to the web and oriented parallel to the tabs. A marker pattern may be formed on each tab to denote a position on each slat for subsequent coupling of metal studs to the tabs.

  • Patent number: 5836133
    Abstract: A vertical movement clip for attaching a channeled beam or stud member to a horizontal building member. The clip has the advantage of easily sliding into the interior of the stud and wedging between two parallel legs of the stud member to fit securely therein. The clip also has the advantage of providing an attachment flange that securely attaches to and holds the floor to the stud and prevents most all horizontal movements and yet allows for vertical floor movement relative to the stud. A second embodiment includes a first and second arm having bent portions for increased loading capacity.
