Structural members
First Claim
1. The design calls for a structural metal member to be formed from triangular structures, made up of four elongated rectangular sheets. Each of the sheets has a long side and a short side. The triangular members are formed from a single folded elongated planar member. The two centrally joined elongated rectangular planar sheets have multiple semi-ellipsoidal indentations on each sheet. These indentations make contact with the two outside pre-formed sheets when the sheets are folded into the elongated triangular member, including three cavities extending through the member.

Abstract
In construction, there currently exist few basic structural members, and few developments of metal load-bearing structures having structural connections with no welding or drilling. The present invention is a new innovative approach to the making of metal structural supports that is more economical, is more time efficient, and provides more strength and rigidity. The recommended design can be used in areas where strong rigid structural members are needed and comes in a variety of sizes, strengths, and weights. It is most suitable for construction purposes but has application in many manufacturing areas where weight, strength, and ease of assembly are desired.

- 1. The design calls for a structural metal member to be formed from triangular structures, made up of four elongated rectangular sheets. Each of the sheets has a long side and a short side. The triangular members are formed from a single folded elongated planar member. The two centrally joined elongated rectangular planar sheets have multiple semi-ellipsoidal indentations on each sheet. These indentations make contact with the two outside pre-formed sheets when the sheets are folded into the elongated triangular member, including three cavities extending through the member.
- 5. A structural member is comprised of two elongated triangular members, made from four elongated rectangular sheets. The triangular members are formed from two folded elongated rectangular planar sheets, each sheet having a long side and a short side. The two centrally joined elongated rectangular planar sheets have multiple semi-ellipsoid indentations, running parallel to and equally spaced along the longer axis.

8. We have an elongated triangular structure member comprised of four elongated sheets. Each sheet has a long edge and a short edge and is joined by its long edge to another sheet. The two joined center planar sheets have numerous semi-ellipsoidal indentations, formed parallel to its long axis.
The two outside sheets have a pre-formed curved surface formed parallel to its long axis. The four rectangular sheets when folded in along the long edge form an elongated triangular structural member. The four said sheets are retained in this triangular form by a stabilizing rod, extending through the member and located in the center of the said structural member.

13. The triangular joining clamp has many semi-ellipsoid indentations extending into the said triangle. The location and the depth of the semi-ellipsoidal indentations are used to position the clamp on the structural member 10 and provide for the expansion and the contraction of the assembly.

16. In design 48, the inside dimension of the cylinder inspection and joining clamp 42 is twenty over a thousand times larger than two times the dimension of the distance between the apex and the true center of a triangular structural member 10. The minimum outside dimension of cylinder 42 is three times the dimension of the distance between the apex and the true center of the triangular structural member. The minimum length of cylinder 42 is five times the distance between the centers of the ellipsoidal indentations 38 and 39 of the structural member 10.
The inside dimension of cylinder 43 is ten over a thousand times larger that the outside dimension of cylinder 42. The minimum outside dimension of cylinder 43 is four times the minimum inside dimension of the between the apex and the true center of a triangular structural member 10.

19. An alternative triangular cylinder safety support and rescue clamp 60 is made up of an internal cylinder 50 with a centrally located triangular form. The triangular form is thirty over a thousand times larger than the outside dimension of the apexes of the alternative safety structural member 10. The minimum outside dimension of cylinder 50 is four times the dimension of the distance between the apex and the true center of the triangular structure member 10. The said structural member 10 is supported within the triangular form by pin bearings 52. Nine or more pin bearings are required for each cylinder. The pin bearings are located at right angles to the apexes of the internal triangular form and require predetermined placements. The apexes of the triangular structure member 10 slide effortless along pin bearings 52.
The minimum length of cylinder 50 is five times the distance between the centers of ellipsoidal indentations 38 and 39. The inside dimension of cylinder 59 is ten over a thousand times larger than the outside dimension of cylinder 50. The minimum outside dimension of cylinder 59 is six times the distance between the apex and the true center of the triangular structure member 10.

20. The steel retaining balls are connected by a suitable wire cable. The clearance distance for the steel retaining balls shall be a minimum of fifteen over a thousand times larger than the outside diameter of the steel balls and wire cables 55.
The internal linear cam 54 is centrally located on the inside wall of cylinder 59. The center distance of the said cams shall be equal to the distance between the centers of the ellipsoidal indentations 38 and 39 in the triangular structural safety member 10. The linear distance the cam travels to engage the ball retainers in both directions shall be no greater than one half inch in any direction, for a total of one inch overall travel.
