Abstract:
1. A stackable transmission line hanger for attaching multiple lines, coaxial cables, electrical cables, waveguides, pipes or lengths of similar products to a supporting structure, comprising: a. a transmission line clasping section comprising an elliptical block, the elliptical block comprising an upper clamping element and a lower clamping element, the clamping elements comprising an outer end, an inner end and two identical flat sides, the outer ends comprising two curved ends and a flat center, the flat center of the upper clamping element comprising a recessed rectangular portion with a square opening that connects to a securing aperture through which an attaching means can pass, creating a securing aperture extending through the inner ends of the upper and lower clamping element when the upper clamping element and lower clamping element are aligned, the flat center of the lower clamping element comprising a square opening that connect to the securing aperture, the inner ends comprising two grasping surfaces with semi-circular cross-sections capable of engaging a transmission line and an interlocking portion between the two grasping surfaces; the interlocking portion of the upper clamping element comprising a rectangular perimeter which is formed by the two grasping surfaces intersecting the sides of the gripping elements, the rectangular perimeter surrounding two male conical posts that extend beyond the rectangular perimeter and a space for the securing aperture between the male conical posts; the interlocking portion of the lower clamping element comprising a rectangular perimeter surrounding two conical female receptors corresponding to the two male conical posts of the upper clamping element and a space for the securing aperture between the conical female receptors, the sides of the lower clamping element comprising a pinhole which intersects the securing aperture capable of receiving a brad; and b. a unitary attachment means, comprising a stacking section and two legs, the stacking section comprising a rectangular top section and two curved sides, the rectangular top section comprising a reinforced circular aperture, the curved sides comprising a unidirectional one hundred eighty degree loop, a ninety degree turn where the stacking section adjoins the legs, resulting in the legs being perpendicular to the rectangular top section of the stacking section, and rectangular gap extending through the curved sides and being longer and wider than the legs, the legs being flat and necked down from the width of the stacking section and narrower than the reinforced circular aperture and comprising an elongated region and an attaching region, the elongated region being between the stacking section and the attaching region and being of sufficient length to extend through the center opening of the cable retention section, the attaching region comprising two opposing notches adjacent to the elongated region and a curved end with a J-shaped cross-section, the curved ends being capable of sliding through and engaging the rectangular gap in the curved sides of the stacking section, the notches being of a length and width capable of engaging the reinforced circular aperture of the rectangular top section; the legs being capable of being pressed toward each other and expanding away from each other when released by spring force, the legs being of such dimensions that they can fit through both the reinforced circular aperture of the rectangular top section and the square opening in the outer ends of the clamping elements when pressed together; the features of the legs and the stacking section resulting in the capability of creating a joint between one attachment means and another and thereby stacking one transmission line hanger onto another.
