Abstract

A section fixable in a mounted position to an anchoring base by means of fastening screws has at least one fastening segment extending in the mounted position substantially parallel to the anchoring base. The fastening segment is, for example, a fastening flange, which is provided with at least one screw hole for receiving a fastening screw provided with a slot or cross slot as the surface engaged by a screwdriver. A safety (or securing) tab protrudes from the fastening segment at least within the area of the screw hole. When the section is in its mounted position and after the fastening screw has been driven in, the safety tab can be deformed by bending or folding it into its safety or securing position. In this position, the tab grips over the edge of the screw head of the fastening screw and leaves free the surface engaged by the screwdriver. In an alternative embodiment of the section, a spring-elastic safety arrest is used instead of a bendable safety tab. As a fastening screw is being driven in, the safety arrest is pushed away sideways by the head of the screw and, after the fastening screw has been completely driven in, the safety arrest snaps into a safety position in which it grips over the edge of the head of the fastening screw.

Claims

1. A section fixable in a mounted position to an anchoring base by means of fastening screws having a screw head with a surface for engaging a screwdriver comprising

at least one fastening segment adapted to extend substantially parallel to the anchoring base in the mounted position,

at least one screw hole disposed in said fastening segment for receiving a fastening screw driven into an installed position in the anchoring base in which the screw head grips over an edge of the screw hole,

a safety tab projecting from the fastening segment at least in the area of the screw hole, said safety tab with the section in the mounted position and the fastening screw in the installed position being deformable into a safety position in which said safety tab grips over an edge of the screw and leaves free the surface engaged by the screwdriver.

2. The section according to claim 1, wherein the safety tab is provided within the area of the screw hole with a release having edges such that in the safety position, the edges of the release grip over the edge of the screw head, leaving free the surface engaged by the screwdriver.

3. The section according to claim 1, further comprising a center part and wherein the safety tab comprises a lengthwise extending safety flange extending from said fastening segment on the side of the fastening segment facing away from the center part, said safety flange being raised upright and bendable into the safety position.

4. The section according to claim 3 comprising a long-stretching hat section and wherein the fastening segments comprise lengthwise extending fastening flanges on both sides of the center part of the section, said fastening flanges having edges provided with raised upright safety flanges.

5. The section according to claim 1, comprising a fastening element for mounting U-shaped ceiling sections comprising a center part and wherein the fastening segments comprise element fastening tabs projecting sideways from the center part on opposite sides, said fastening tabs each being penetrated by a screw hole, and where on the sides facing away from the center part, the safety tab is raised upright on each side from the fastening tabs, said safety tab being bendable into the safety position in which it grips over the edge of the screw head.

6. A section fixable in a mounted position to an anchoring base by means of fastening screws having a screw head with a slotted surface for engaging a screwdriver comprising of:

at least one fastening segment adapted to extend substantially parallel to the anchoring base in the mounted position,

at least one screw hole disposed in said fastening segment for receiving a fastening screw driven into an installed position in the anchoring base whereby the screw head grips over an edge of the screw hole,

a safety arrest having a spring elasticity projecting on at least one side from the fastening segment at least in the area of the screw hole, said safety arrest being pushed away sideways by the screw head when the fastening screw is driven into the installed position, said safety arrest when the section is in the mounted position snapping into a safety position in which said safety arrest grips over an edge of the screw head and leaves free the surface engaged by the screwdriver.

7. The section according to claim 6, wherein the section comprises a center part and the safety arrest comprises a spring leg projecting from the side of the fastening segment facing away from the center part to form a slanted surface ascending toward the fastening segment, said spring leg being spring-elastically connected with the fastening segment via an approximately C-shaped spring segment.

8. The section according to claim 7 comprising a long-stretching hat section, two fastening segments and two spring legs, said fastening segments comprising retaining flanges extending lengthwise on each side of said section, said spring elements extending lengthwise on the other side of each retaining flange and projecting from each side of said section in the form of an approximately C-shaped spring segment, said spring legs diverging from each other.

9. The section according to claim 6 comprising a long-stretching hat section having a fastening segment, a support flange extending lengthwise on each side of the fastening segment, a section bridge connecting each support flange with a respective side of the fastening segment and a plurality of safety arrests, said support flanges extending in planes substantially parallel to the fastening segment and adapted for mounting flat covering elements, said safety arrests comprising lengthwise extending corrugations molded into the safety bridges extending between the support flanges and the fastening segment, said safety corrugations gripping over the edge of the screw head of an installed fastening screw in the installed position.

10. The section according to claim 9, wherein the length-wise extending corrugations are limited toward the side pointing away from the fastening segment by slanted surfaces diverging from each other, and on the side pointing to the fastening segment by steps forming undercuts of the section bridges.
