POST CLAMP
ABSTRACT
Disclosed is an alternative method of stabilizing a vertical fence post as used in chain link fencing, from that commonly use, namely a concrete footing. It incorporates a clamping structure of two symmetrical pieces which are nested together encircling the post and then embedded into the ground about the post as by jack hammer and the like so as to be jux-taposed with the post but to provide lateral fins extending radially therefrom whereby stabilization is effected by the clamp structure.
POST CLAMP
ABSTRACT
Disclosed is an alternative method of stabilizing a vertical fence post as used in chain link fencing, from that commonly use, namely a concrete footing. It incorporates a clamping structure of two symmetrical pieces which are nested together encircling the post and then embedded into the ground about the post as by jack hammer and the like so as to be jux-taposed with the post but to provide lateral fins extending radially therefrom whereby stabilization is effected by the clamp structure.
Description
~ ~t;~ 3 \
This invention relates to a post clamp and particularly to a post clamp for securing, without concrete, a vertical fence post in the ground.
In the prior art, it is known that ence posts, particu-larly metal cylindrical fence posts, which are comrnonly used as the vertical uprising stabilizers for chain link fences, should be embedded in a concrete footing for proper stabiliza-tion. This is particularly true in those temperate regions which experience seasonal thawing and freezing cycles as is common in Canada, and in most of the states of the United State of America.
In most commercial and institutional applications for chain link fencing, the additional cost for concrete footing is not prohibitive. This is not true for domestic applica-tions, whether for boundary marking between adjacent lots or for enclosing a swimming pool in order to satisfy safety stan-dards established under ordinance or by-law of the appropriate municipality or other authority.
The invention therefore has as one of its objects to provide a simple footing device into which a cylindrical metal post or the like can be inserted, for stabilizing the post in the soil.
The invention therefore contemplates an article of manu-facture, namely a clamp structure, comprising;
(a) a piece of rigid sheet material of rectalinear shape, defining a longitudinal and a lateral extent thereof, and edges thereto;
(b) a bend from edge to edge along the lateral extent of the sheet disposing the same with arms at right anglesJ and, (c) a slot in each arm, equadistant rom the bend, extending from a common edge laterally to at least the longitudinal centre line of the sheet.
The invention also contemplates a fence ~upport system employing ~ence posts wherein;
(a) a pair of clamp structures as aforesaid, are placed about the post and embedded into the ground so that ;3 slots of one clamp structure nesk into slots of the other clamp structure or structures encircle the post, each structure thereby defining that portiorl of each arm extending from slot through bend to the opposite slot thereof in juxtaposition with the post.
The invention further contemplates a method of fence post stabilization comprising the steps;
(a) selecting a pair of clamp structures as aforesaid;
(b) selecting, as a fence post a longitudinal cylindri-cal member;
(c) embedding one end of the longitudinal cylindrical member into the ground;
(d) nesting each slot of one clamp structure with that of the other clamp structure while disposing the longi-tudinal cylindrical member to extend through such nested clamp structures whereby to be juxtaposed with that portion of each arm from slot through bend to opposite slot;
(e) penetrating the nested structure of step (d) into the ground so that the same is totally at an elevation below grade.
The invention will now be described by way of example and reference to the accompanying drawings in which;
Figure 1 is a perspective view of a clamp structure according to the invention, and as well as an assembly view of two such structures stabilizing a post.
Figure 2 is an elevational view, sectional through the ground, of a fence incorporating a plurality of fence posts, each fence post stabilized with a pair of clamp structures according to figure 1.
Figure 3 is a section along III-III of figure 2.
Figure 4 is a plan sectional view, at ground elevation, of another embodiment of the invention when a 4 x 4 wooden post is used as fence post.
Referring to figure 1, a unique clamp structure is generally indicated as 10 and is composed of rigid sheet material such as galvanized steel of approximately 3 mm in thickness or stainless steel, has a lateral extent of approxi-mately 4 inches and a longitudinal extent of approximately 10 inches. It is bent along its lateral centre at 11 to form form orthogonally disposed arms 12 and 13 or equal length. In each arm a slot 15 is provided ~lhose depth D is preferably 1/2 the lateral extent. The slot has a width W and is disposed from the bend 11 a distance d.
Two of these clamp structures 10 are used as stabilizing members for vertical fence posts and referring to figures 2 and 3, the two clamp structures act as stabilizing fins 100 for each fence post 55. When a chain link fence is used, the vertical fence posts 55 are galvanized hollow steel posts generally in the vicinity of 1 7/8 inches in diameter and ex-tend below grade and into the ground between 2 foot to 3 feet or more. Typically, the steel fence post is driven into the ground by jack hammer and the like. Then a pair of clamp structures, according to the invention, are placed into nes-ting relationship encircling the post as shown so that the bends 11 of each clamp structure are in relative juxtaposition thereto. The nested clamp structure is then embedded into the ground again by jack hammer or the like so that it is totally below grade as indicated in figure 2.
Referring to figure 3, a tight clamp is formed by that region bounded between slot 15, bend 11 and slot 15 of each clamp structure 10. Preferably therefore, and referring to figure 1, the dimension d, that is the distance between bend 11 and slot 15, is the same or slightly larger than, within a few thousandths of an inch, the outside diameter of the cylin-drical post 55. (In some domestic applications it has become practice to use vinyl posts rather than steel; thus the clamp dimensions become critical if it is desired not to "grasp the post to hard and thereby buckle it.) In this way the mating slots 15 of each clamp structure cause the clamp structure pair to be urgingly juxtaposed against the post 55. This en-hances stabilization. The post 55 preferably penetrates into the ground and extends through the clamp structure by a fur-ther 20 to 30 inches and hence the total dimension of the post 76~
from ground level or grade to that end tha-t is penetrated into the ground is about 39 inches or more.
Returning to figure 2, a plurality o pairs of clamp structures 100 may be stacked on top of one another, as shown in position 90. This may be necessary wherein the ground is sandy soil and the number of stacked pairs of clamps 100 is selected so as to provide the necessary rigidity.
~ y invention is not confined to utilization of the clamp structure for cylindrical steel posts. Square wooden posts can be equally stabilized with a clamp structure. Referring to figure 4, a sectonal view of a typical 4 inch x 4 inch wooden post is shown wherein a pair of clamp structures 100 are used which are identical to those earlier described in relation to the aforesaid figure 1 save and except as to dimension. The distance d therefore of the clamp of figure 4 is 4 inches rather than as earlier disclosed in figure 1 so as accommodate each of the sides of the cross-sectionally square post. The total length of each clamp structure from arm through bend to other arm is 12 inches. In instalation, since it is extremely difficult to pound in a wooden post, as this generally leads to its destruction, an auger is used to drill out a hole, shown in figure 4 in phantom, typically the hole diameter is about 6 inches. The cross-sectionally square wooden post is thus inserted into the hole, the clamps pounded into position and the hole back filled in the conventional manner.
Those skilled in the art will appreciate that certain variations to the invention as claimed may be possible without deviating from the invention as claimed.
