DESCRIPTION:
BRIEF SUMMARY
The invention relates to a fence post for enclosing or limiting purposes of rigid grid boards forming the fence surface, the boards being made of intersecting rods which are connected to one another at the intersection points.
BACKGROUND OF THE INVENTION
A fence post of this type is known from EP 472 760 A1. This fence post comprises a narrow, upright grid board having vertical rods at both edges and connecting, short, straight, horizontal rods connecting the vertical rods in a ladder-like fashion. At least a few of these rods project forward over the vertical grid rods that form the front side of the fence post and are bent around upward in a hook-like manner. The grid boards that form the fence surfaces are laid into these hooks and are retained by screws in the hooks.
A similar fence post is known from DE 39 20 108 C1. The vertical grid rods of the fence post are also connected by means of ladder-like, short, straight, horizontal grid rods from which at least a few project forward over the front side of the fence post where they are bent into eyes that are disposed in horizontal planes in a certain distance from the front side. The grid boards that form the fence surface are laid on the projecting ends of the horizontal grid rods of the fence post and are fixed by means of a vertical, rod-shaped retaining element extended through the eyes. In this specific embodiment, all of the upright grid rods of the fence post can be vertical; yet it is also possible that the fence post becomes wider toward the bottom to increase the stability.
In both known specific embodiments, the vertical grid rods of the fence post can be arranged to be directly opposite one another as double rods at both sides of the horizontal grid rods.
It is difficult to handle the numerous short, horizontal rods for compiling the above known fence posts in machine production of the fence posts by means of resistance spot welding because the hooks or eyes at the horizontal rods are bent prior to welding and the horizontal rods must be welded in a specified rotated position.
Further, the known fence posts are problematic because on their side opposite to the grid board that forms the fence surface many, fairly sharp, freely accessible edges are present by the ends of the horizontal grid rods, which edges can lead to injuries.
SUMMARY OF THE INVENTION
The object of the invention is to improve a fence post of this type with regard to its production and safety from injury.
By means of the embodiment as a bracket, two shanks that are adjacent to one another in elevation form a one-piece part, which on the one hand is larger and only insofar allows simplified handling in contrast to the individual horizontal grid rods of fence posts of the related art, and on the other hand, exhibits a two-dimensional extension such that the projecting ends are always correctly oriented with regard to their design as retaining elements without particular effort and difficulties from accidental rotation of the horizontal rods about their longitudinal axes are eliminated.
On the side opposite the fence surface, hence the web side of the bracket, the bracket is closed and free of ends that form sharp edges such that the risk of injuries is substantially less.
Component of the invention is that the upright rods of the fence post are only provided on one side of the brackets, however, in the preferred specific embodiment, the upright rods are provided on both sides of the brackets in pairs directly opposite one another, to increase the bending strength of the fence post.
The upright rods can diverge downward away from one another in order to increase the base of the fence post and its stability perpendicular to the fence surface.
The preferred specific embodiment, however, provides for upright rods parallel to one another because this accommodates the production of the fence post on an automatic grid welding machine.
For stress on a fence post consisting of grid material, whose connection rods extend essentially horizontally, the forces that arise are predominan
