Post for enclosures

Abstract

To create a post for enclosures, partitions, and similar structures consisting of several parts and involving a strip of hollow structural section that will allow the rapid and rational assembly of such enclosures as bar-grid fences and similar structures, whereby disassembly will be impossible without destroying the components, the length (2) of hollow structural section has a gap along one side flanked by two separated flanges (3), which extend either inward or outward and between which are accommodated webs (4) that match the shape of each flange and that are part of a length (5) of more or less T or .pi.-shaped structural section that closes off the gap, leaving room outside on each side of the flanges between the length of hollow structural section and the matching sections of a spine (6) on a length (5) of T or .pi.-shaped structural section, whereby the length of T or .pi.-shaped structural section can be locked into the length of hollow structural section.

Description

The invention concerns a post for enclosures, partitions, and similar structures consisting of several parts and involving a strip of hollow structural section.

Posts for wire-grid fences and consisting of rectangular pipes with welded-on tabs that the wire grid can be secured to with compression strips and screws are known. There is, however, a drawback to the known posts in that the fence can always be disassembled by unauthorized persons and accordingly rendered penetrable. Assembly also takes a lot of time.

The object of the present invention is accordingly to create a post of the type initially described that will allow the rapid and rational assembly of such enclosures as bar-grid fences and similar structures, whereby disassembly will be impossible without destroying the components.

The object is attained in accordance with the invention by the characteristics recited in the body of claim 1.

Practical developments are recited in claims 2 through 13.

The particular advantages of the post in accordance with the invention are that it allows simple and rapid assembly of bar-grid fences and similar structures for example but can be rendered penetrable only by destroying its components, a property that satisfies strict security demands in that it has no separable components like screws, rivets, securing tabs, etc. for example.

The post in accordnce with the invention will now be specified with reference to the drawing, wherein

FIG. 1 is a top view of one embodiment of an assembled post,

FIG. 2 is a front view of the post in FIG. 1,

FIG. 3 is a side view of the posts in FIGS. 1 and 2,

FIG. 4 illustrates various embodiments of the hollow structural section that the post is made out of,

FIG. 5 illustrates various embodiments of the .pi.-shaped structural section that is employed with the post,

FIG. 6 illustrates various embodiments of the rod that secures the post,

FIG. 7 illustrates an embodiment of a top for the post, and

FIG. 8 is a top view of another embodiment of an assembled post.

As will be evident from FIGS. 1 through 3, a post 1 consists of a length 2 of hollow square structural section with a gap along one side flanked by two separated and outwardly extending flanges 3, between which are accommodated webs 4 that match the shape of each flange and that are part of a length 5 of T-shaped or .pi.-shaped structural section that closes off the gap, leaving room for bar grids 7 on each side of flanges 3 between length 2 of hollow structural section and the matching sections of a spine 6 on a length 5 of .pi.-shaped structural section, whereby spine 6 is as wide as length 2 of hollow structural section.

The ends of webs 4 extend into length 2 of hollow structural section and have recesses 8 toward the inside of the wall of length 2, with their ends facing each other again and mutually partly surrounding one or more locking rods 9 accommodated between them, securing length 5 of .pi.-shaped structural section into length 2 of hollow structural section.

The flanges 3 on length 2 of hollow structural section and the webs 4 on length 5 of .pi.-shaped structural section have matching slots 10 and 11 for accommodating a suspendable U-shaped bolt 12 that provides additional security to prevent spreading length 2 of hollow structural section open and secures length 5 of .pi.-shaped structural section. The slots 11 in the webs 4 on length 5 of .pi.-shaped structural section extend along post 1 and the slots 10 in the flanges 3 on length 2 of hollow structural section extend across the post. Slots 11 are as wide and slots 10 as long as the legs of U-shaped bolt 12.

Tabs 13 are welded to the sides of length 2 of hollow structural section that face the spine 6 on length 5 of .pi.-shaped structural section and prevent the grid from being extracted.

Welded to the top of post 1 is a face plate 14 that has an opening 15 to insert locking rod 9 through and that can be closed off with a cap 16.

To assemble the fence, bar grids 7 are suspended over the tabs 13 on lengths 2 of hollow structural section that have been anchored into the ground, matching lengths 5 of .pi.-shaped structural section are inserted to prevent bar grids 7 from falling out and collapsing, locking rods 9 are inserted through the openings 15 in face plates 14, and the openings are closed off with caps 16, preventing the fence from being disassembled without destroying its components.

FIG. 4 illustrates various embodiments of length 2 of hollow structural section with flanges 3:

(a) quadrilateral, (b) triangular, (c) half-round, (d) round, and (e) polygonal, whereby flanges 3 can point inward, although the situation is not illustrated.

FIG. 5 illustrates various embodiments of length 5 of .pi.-shaped structural section with webs 4, spine 6, and recesses 8, whereby

(a) has a flat spine 6, (b) has a spine 6 that is bent slightly on both sides along its total length, (c) has a spine 6, intended for example for a terminal post, that is bent all the way in on one side, and (d) has a spine 6 that is bent slightly in only at edges.

FIG. 6 illustrates various embodiments of locking rod 9:

(a) round, (b) triangular, (c) oblong, (d) square, and (e) polygonal.

FIG. 7 represents a face plate 14 that snaps into the top of post 1 and cannot be removed from it. Welded to the inner surface of face plate 14 is a spring-loaded clip 17 that operates in conjunction with a transverse rib 18 welded into length 2 of hollow structural section to reinforce it.

FIG. 8 illustrates a post 1 with a length 2 of hollow structural section that has flanges 3 that face inward with webs 4 that match the flanges positioned between them. The webs are part of a length 5 of .pi.-shaped structural section with a spine 6. The recesses 8 on webs 4 engage matching recesses 19 in the flanges 3 on length 2 of hollow structural section, and the webs 4 also have recesses 20 that engage the ends of flanges 3.

To improve protection against corrosion, posts 1 are made out of corrosion-resistant and/or coated materials.

The posts in accordance with the invention can of course also be employed in partitions, balustrades, wind, sun, antiglare, antinoise, and privacy screens, to construct containers, frameworks, connecting systems, ceiling suspension systems, and built-in cabinets, and in the automotive industry etc.
