Abstract
An car antenna having anti-theft features including a rod for receiving radio-frequency signals; a support base to be secured to a support surface; and a joint secured in the base. The rod or the joint includes an elastic element for allowing the base and joint to be unidirectionally coupled and snapped together. The joint may also include articulating portions allowing the antenna position to be adjusted.
Claims22
An antenna comprising a rod for receiving radio frequency signals and a support base having a surface adapted to be secured to a support surface, a joint element secured within said support base for supporting said rod, said joint element having a first hole formed therein, said rod including an elongated elastic terminal element having a longitudinal axis adapted to be unidirectionally inserted and snapped into said first hole, said terminal element including a terminal body having a free end, an elastically deformable clutch head being formed at said free end and including a slanting surface allowing deformation of said terminal element during passage through the first hole, said first hole having a smaller cross-section than the maximum cross-section of the undeformed clutch head, said clutch head being formed with a notch extending along said longitudinal axis providing deformability to said clutch head, said clutch head having an outer perimeter and a flat rear facing surface being disposed between said outer perimeter and said terminal body, said joint element having formed therein a second hole of greater cross section than said first hole to define an inner surface at the intersection of said first and second holes for engaging the flat rear facing surface of the clutch head when said clutch head is inserted into and clears the first hole for securing the rod and support base together.
An antenna support comprising;
- a rod;
- a supporting base;
- an articulating joint connecting the rod to the supporting base, said articulated joint including a first articulation element and first connecting means rigidly connecting the first articulation element to the supporting base, and a second articulating element and second connecting means for connecting said rod to said second articulation element, said first and second articulation elements being rotatable with respect to each other permitting selectable orientation of the rod with respect to the base, each including contacting means movable with respect to each other for fixedly securing the rod in a selected orientation by reciprocal interference therebetween, and means engaging at least one of said connecting means reciprocally engaging the first and second articulation elements together;
- and
- wherein the first and second articulation elements include means associated therewith for unidirectionally connecting the rod to the base.
