Metal channel anchor with enhanced holding strength

1. A longitudinal channel providing increased holding strength, configured for use as an anchoring element for an anchor used in supporting objects on a substrate, the channel comprising a generally U-shaped axial cross section in at least a portion thereof, the U-shaped cross section being comprised of longitudinal side walls and a longitudinal base section as a connection between the side walls with the side walls having edges configured for holding contact with the substrate;

wherein a portion of the edges of the channel are covered with a planar continuous surface material which is co-extensive with non-covered edges, wherein the channel is comprised of metal and whereby the planar continuous surface material and the edges provide a planar holding surface with greater surface area than that of the edges alone, for the increased holding strength, wherein the longitudinal base section is apertured in the center thereof with a threaded aperture configured for threaded engagement with a threaded holding element and wherein the planar holding surface is only positioned on one side of the aperture in a longitudinal direction of the channel, whereby at least one longitudinal manipulating element, rotatably attached to the channel, is capable of being fitted into the channel on a second side of the aperture during placement of the channel through an aperture in the substrate, wherein the planar continuous surface material comprises a covering section positioned on a recessed portion of the edges to provide the planar holding surface and wherein the channel comprises an integral one piece element, wherein a portion thereof is folded over and fitted into the recessed portion and comprises the planar holding surface.

2. The longitudinal channel of claim 1 wherein the planar holding surface comprises a surface of partially or completely filled in volume between a portion of the side walls filled up to the level of the edges to provide the planar holding surface to a level of the edges.

3. The longitudinal channel of claim 1 , wherein an end portion of the longitudinal base connection extending beyond facing ends of the longitudinal side walls is folded with a first fold to cover an end of the longitudinal channel and further folded with a second fold to cover a portion of the longitudinal channel, the second fold being fitted upon facingly recessed portions of terminal portions of facing ends of the longitudinal side walls with each recessed portion having a depth equal to a thickness of the end portion, thereby providing the planar holding surface.

4. An anchor configured for supporting objects on a substrate comprising the longitudinal channel of claim 1 , the at least one longitudinal manipulating element rotatably connected to the longitudinal channel for positioning the longitudinal channel into a load bearing holding position on a non accessible surface of the substrate, and a position fixing member for fixing the longitudinal channel into the load bearing holding position.
