Description
CROSS REFERENCE TO RELATED APPLICATIONS
[0001] This application claims priority to U.S. Provisional Patent
Application No. 61/383,772, filed on Sep. 17, 2010, to Lill, the
disclosure of which is incorporated herein by reference in its
entirety.
BACKGROUND
[0002] 1. Field of the Disclosed Embodiments
[0003] The disclosed embodiments relate to a barrier for preventing
animals from crossing onto a roadway.
[0004] 2. Background of the Disclosed Embodiments
[0005] A structure is required which is suitable for providing a
fence surface which prevents turtles and other wildlife from
crossing onto a road when other means of connecting manmade
obstructions, such as guardrail structures, are unavailable. The
structure should be modular so as to enable the creation of miles
of roadway barriers.
SUMMARY OF THE DISCLOSED EMBODIMENTS
[0006] A barrier for preventing wildlife from entering a roadway is
disclosed. The barrier includes a plate having a bottom edge
adapted for piercing a ground surface, and at least one opening in
the plate for connecting a corresponding at least one post to the
ground so as to provide additional vertical support for the
plate.
BRIEF DESCRIPTION OF THE FIGURES
[0007] Figures are provided, which are not limiting, and in
which:
[0008] FIG. 1 illustrates a top view of the disclosed barrier;
[0009] FIG. 2 illustrates a front view of the disclosed
barrier;
[0010] FIG. 3 illustrates a perspective view of the disclosed
barrier;
[0011] FIG. 4 illustrates a perspective view of a post for the
disclosed barrier;
[0012] FIG. 5 illustrates one side view of the post;
[0013] FIG. 6 illustrates another side view of the post; and
[0014] FIG. 7 is a top view of the spike.
DETAILED DESCRIPTION OF THE DISCLOSED EMBODIMENTS
[0015] FIGS. 1-3 illustrate a grate wall 10 having a vertical plate
10 and a horizontal return or flange 14. The plate and flange 10,
14 can be unitary, connected at a bend 16, or can be separate
plates welded together. The material can be sixteen gauge
galvanized steel. The width of the plate 10, from proximate end 18
to distal end 20, is approximately four feet while its height,
bottom 26 to top 22, is approximately ten inches. The depth of the
flange, front 22 to back 24, is approximately between two and two
and a half inches. In addition, reference has been made to
"proximate" and "distal" ends. In the illustration, the proximate
side is the right side and the distal side is the left side of the
figures.
[0016] The bottom edge 26 of the vertical plate 12 has a profile
comprising a bank 28 of continuously oriented triangular serrations
or notches. Each notch, e.g., notch 28, is substantially similar
and is approximately an inch in height and two inches wide, trough
27 to trough 29, that is, vertical low point to vertical low point,
with peaks therebetween. The bank of notches 30 enables pushing the
wall 10, bottom edge 26 first, into a ground surface.
[0017] Once in place, in a ground, use is made of a bank of slots
32 widthwise spaced on the flange 14, including slot 34, each of
which having substantially the same size and shape. For example,
slot 34 has a V-shape, with the peak or center joint 36 of each
slot positioned mid-depth in the flange 14 and facing a common side
of the flange, e.g., distal side edge 38. Each side slot 40, 42 of
each "V" shaped slot extends towards the proximate edge 44 of the
flange 14 by an angle of about forty-five degrees from a widthwise
extending centerline 46 of the flange. Thus, a ninety degree angle
exists between each side slot 40, 42.
[0018] The illustration provides for three such slots 44, 47, 48 in
the bank of slots. However two slots 44, 47 can be provided at
opposing proximate and distal ends 38, 44 of the flange 14,
omitting the center slot 48. Alternatively, more slots can be
provided as needed.
[0019] Into each slot, a post 50 illustrated in FIGS. 4-7 is
provided, which is fabricated from the same material as the grate
wall 10. Each post 50 has a cross sectional shape, defined by
connected side walls 52, 54, connected at a central joint 55, which
is configured to enable passing substantially freely into the
individual slots 34, 47, 48 in the bank of slots 32. As
illustrated, each side wall 52, 54, is about an inch long. Each
post 50 functions as a spike for spiking the grate wall 10 into the
ground and vertically supporting the grate wall 10 at an embedded
location.
[0020] Assisting in the embedding process is a bank of tabs 56 in
each post 50 which includes, e.g., tab 58 on side wall 54, which is
representative of each tab. The tab 58 is angled outwardly from its
connecting joint 60 on the side wall 54 by about twenty to thirty
degrees from the vertical, when the post is vertically oriented,
and is approximately a half inch long and has a square surface
area. There are approximately twelve aligned tabs on each wall 52,
54 in the post defining the bank of tabs 56. The tabs provide a
scoping function which resists pulling the posts from the ground
and from the slot in the grate wall flange.
[0021] Each post 50 is about two feet long and the side walls 52,
54 of each post 50 each have an angled or chamfered bottom end 62,
64, with, for example, a twenty to thirty degree outward pitch. The
chamfered bottom creates a spike 66 or a "V" from the perspective
view (FIG. 4), for piercing the ground.
[0022] A top cap 68 on the post, horizontally positioned when the
post is vertically disposed, enables hammering the post into the
ground. The cap 68 is essentially a quarter-round plate, an inch on
each side, which spans the top edges of the spike 66 formed by the
side walls 52, 54.
[0023] The above structure is suitable for providing a fence
surface, preventing turtles and other wildlife from crossing onto a
road when other means of connecting obstructions, such as guardrail
structures, are unavailable. The grate wall can be adjacently
positioned next to other grate wall structures, creating miles of
roadway barriers.
[0024] Accordingly, a barrier for preventing wildlife from entering
a roadway has been disclosed. Generally, the barrier includes a
plate having a bottom edge adapted for piercing a ground surface,
and at least one opening in the plate for connecting a
corresponding at least one post to the ground so as to provide
additional vertical support for the plate.
[0025] Alternatively, the plate can be a mesh nylon polypropylene
material between the posts instead of a plate. While certain
advantages exist with a plate, such as its inherent stability and
ability to pierce the ground, and the additional stability provided
by the integrated flange. However, the mesh material would provide
a less expensive alternative. In addition, a cross member could be
snaked through the mesh fence, between the posts, along top or
bottom fence edges, or vertically between those edges, such as a
one tall by quarter inch thick plate which spans the distance
between the posts. Such would provide at least some horizontal
stability otherwise lost by utilizing a mesh instead of the
disclosed plate.
[0026] The disclosed embodiments may be configured in other
specific forms without departing from the spirit or essential
characteristics identified herein. The embodiments are in all
respects only as illustrative and not as restrictive. The scope of
the embodiments is, therefore, indicated by the appended claims and
their combination in whole or in part rather than by the foregoing
description. All changes that come within the meaning and range of
equivalency of the claims are to be embraced within their
scope.
