A cable system for erecting a barricade such as, for example, a security fence, on a support surface such as, for example, the perimeter of an area to be protected. The cable system is uniquely characterized by the structure of the hollow support posts, or bollards, and their fittings for the attachment of lengths of cable thereto to provide a barricade having high strength. Lengths of cable not only extend between adjacent posts, but each end of each cable length passes through the hollow void of each post for attachment thereto below the support surface. Each of the posts used in the system is preferably set in concrete, and the hollow void of each individual post is also filled with concrete. Also disclosed is a preferred structure for an individual post.
1. A cable system for constructing a barricade above a support surface, said cable system comprising: a plurality of hollow posts disposed on the support surface in longitudinally spaced apart relation to each other, each one of said plurality of posts being defined by a top edge, a bottom edge, a front side, a rear side, a left side and a right side, with the length of each one of said plurality of posts being defined by the distance between said top edge and said bottom edge; a plurality of post base plates, each one of said plurality of base plates being attached to a corresponding one of said plurality of posts at said bottom edge in substantially transverse relation to said length; a plurality of opposed pairs of eye bolts, each one of said opposed pairs having a first end attached to a corresponding one of said plurality of base plates and a distal end comprising an eye extending upwardly from said base plates in substantially parallel relation to said length of each one of said plurality of posts, one of each one of said pair of eye bolts being disposed in spaced apart relation to said left side of each one of said plurality of posts and the other of each one of said pair of eye bolts being disposed in spaced apart relation to said right side of each one of said plurality of posts; a plurality of cable receivers, each one of said plurality of cable receivers having a first end and a second end, each one of said cable receiver first ends being connected to a corresponding one of said eyes of each one of said plurality of eye bolts; a plurality of left lower cable apertures, one of each one of said plurality of left lower cable apertures being formed through each one of said left sides of each one of said plurality of posts and a corresponding plurality of right lower cable apertures, one of each one of said plurality of right lower cable apertures being formed through each one of said right sides of each one of said plurality of posts; a plurality of left middle cable apertures, one of each one of said plurality of left middle cable apertures being formed through each one of said left sides of each one of said plurality of posts above a corresponding one of said left lower cable apertures and a corresponding plurality of right middle cable apertures, one of each one of said plurality of right middle cable apertures being formed through each one of said right sides of each one of said plurality of posts above a corresponding one of said lower cable apertures; a plurality of left upper cable apertures, one of each one of said plurality of left upper cable apertures being formed through each one of said left sides of each one of said plurality of posts above a corresponding one of said left middle cable apertures and a corresponding plurality of right upper cable apertures, one of each one of said plurality of right upper cable apertures being formed through each one of said right sides of each one of said plurality of posts above a corresponding one of said right middle cable apertures; and a plurality of cables, each one of said plurality of cables having a first cable end and a second cable end, said first cable end of each one of said plurality of cables being attached to said second end of one of said cable receivers of one of said posts and said second cable end of each one of said plurality of cables being attached to said second end of one of said cable receivers of a different one of said posts.
2. A cable system as in claim 1 wherein a segment of said length of each of said plurality of posts including said lower left and lower right cable apertures is disposed below the support surface.
3. A cable system as in claim 1 wherein each one of said second ends of each one of said cable receivers is in communicating relation to a corresponding one of said lower cable apertures in receiving relation to one of said ends of one of said plurality of cables, whereby one of said ends of each of said plurality of cables is received and retained in a corresponding one of said cable receivers.
4. A cable system as in claim 1 wherein a segment of said length of each of said plurality of posts including said middle left and middle right cable apertures is disposed above the support surface.
5. A cable system as in claim 1 wherein each of said plurality of middle cable apertures and each of said plurality of upper cable apertures defines a substantially teardrop perimeter, with the smaller radius of said teardrop perimeter being disposed toward said bottom edge of each of said plurality of posts.
6. A cable system as in claim 5 further comprising a plurality of cable guides, one of each of said plurality of cable guides being disposed at said smaller radius of each of said plurality of middle cable apertures and each of said upper cable apertures, whereby a segment of one of said plurality of cables passing through one of said middle cable apertures and a segment of another one of said plurality of cables passing through one of said upper cable apertures will be received in a corresponding one of said plurality of cable guides.
7. A cable system as in claim 1 further comprising a plurality of cover plates, one of each of said plurality of cover plates being disposed in substantially surrounding, enclosing relation to each one of said cable apertures.
8. A cable system as in claim 7 further comprising concrete filling said hollow of each one of said plurality of posts from said base plate to said top edge.
9. A post used for erecting a cable system barricade on a support surface, said post comprising: a top edge, a bottom edge, a front side, a rear side, a left side and a right side, a length of said post being defined by the distance between said top edge and said bottom edge, said post further comprising a hollow interior defined by said front, rear, left and right sides; a post base plate attached at said bottom edge in substantially transverse relation to said length; an opposed pair of eye bolts, each one of said opposed pair having a first end attached to said base plate and a distal end comprising an eye extending upwardly from said base plate in substantially parallel relation to said length, one of said pair being disposed in spaced apart relation to said left side of said post and the other of said pair being disposed in spaced apart relation to said right side of said post; a pair of cable receivers each having a first end and a second end, each of said cable receiver first ends being connected to a corresponding one of said eyes of each one of said pair of eye bolts; a left lower cable aperture formed through said post left side in communicating relation to one of said cable receiver second ends; a right lower cable aperture formed through said post right side in communicating relation to the other of said cable receiver second ends; a left middle cable aperture formed through said post left side above said left lower cable aperture; a right middle cable aperture formed through said post right side above said right lower cable aperture; a left upper cable aperture formed through said post left side above said left middle cable aperture; and a right upper cable aperture formed through said post right side above said right middle cable aperture.
10. A post as in claim 9 wherein each of said left and right middle cable apertures and each of said left and right upper cable apertures defines a substantially teardrop perimeter, with the smaller radius of said teardrop perimeter being disposed toward said bottom edge of said post.
11. A post as in claim 10 further comprising a plurality of cable guides, one of each of said plurality of cable guides being disposed at said smaller radius of each of said left and right middle cable apertures and at said smaller radius of each of said left and right upper cable apertures.
