PORTABLE FENCE PANEL
Abstract
A portable fence panel is arranged for connection to identical
panels for use as a pen or corral. Each panel has a generally
rectangular frame which holds a wire barrier. A trio of tubes is
mounted both at the top and bottom of one end post. An inverted
U-shaped stud is mounted both at the top and bottom of the other
end post for fitting into selected tubes. By providing the trio of
tubes, a four-way fence corner can be easily constructed. A
releasable locking mechanism is mounted below the stud to underlie
the tubes and prevent disconnection.

Description
BACKGROUND
The invention pertains generally to animal husbandry and more
particularly to a portable fence panel to provide a pen for
livestock.
Fences of various kinds have been provided for the retention of
livestock of a more or less permanent nature including posts
embedded in the earth with connecting structure, all of which was
relatively heavy requiring substantial materials, labor and skill
in the fabrication thereof. Such structures have lacked flexibility
to be adjusted to areas of varying sizes and consequently imposed a
substantial problem in the provision of adequate corral-forming
fencing. Temporary or portable fence panels overcome the above
problems, and one such panel is shown in U. S. Pat. No. 3,204,606
issued Sept. 7, 1965 to Parr et al. In that prior patent, however,
both ends of the panel were similar so it could not be easily
determined how the panels were to be fitted together.
SUMMARY
The present invention relates to a portable fence panel for
livestock pens.
It is an object of the present invention to provide a portable
fence panel of strong, durable construction, capable of being
connected to identical panels to provide a pen for a variety of
livestock.
Another object is to provide a portable fence panel having a
construction which can be readily connected to identical panels and
which is apparent which parts are to be interfitted for such
connection, so that erection can be accomplished by a minimum of
workmen in a minimum of time.
Still another object of the invention is to provide a portable
fence panel which can be connected to identical panels to form
rectangular and polygonal pens of any desired size and which pens
are usable as holding pens, field corrals, temporary stalls, and
the like.
It is another object to provide a portable fence panel for
connection to an identical panel and which means for temporarily
locking the two panels together.
These, together with other objects and advantages of the invention,
will become apparent as the invention becomes better understood
from the following description when taken in conjunction with the
accompanying drawings.

fence panels of the present invention connected to provide three
pens;

which the male members are mounted.
DESCRIPTION
Reference is now made more particularly to the drawings which
illustrate the best presently known mode of carryng out the
invention and wherein similar reference characters indicate the
same parts throughout the several views.
A preferred embodiment of a portable fence panel 10 includes
vertical end posts 11 and 12 which are connected by upper and lower
rails 13 and 14, respectively. The end posts and rails are
advantageously formed of a one inch diameter steel tube with the
lower rail 14 welded to the end posts. The upper rail 13 may be an
integral continuation of the end posts 11 and 12, as shown. The
posts and rails provide a generally rectangular frame which
supports a barrier 15 therebetween. The barrier may be of wire rod
stock to retain smaller livestock or of steel tubing for larger
livestock. In either event, the barrier is preferably welded to the
frame.
Connector means are provided for connecting each portable fence
panel 10 to similar portable fence panels. The connector means
includes first and second female members 20, 20' on the first end
post 11. As best seen in FIG. 4, the female members 20, 20' are
vertically spaced at locations adjacent the upper and lower rails
13 and 14. Each female member provides three openings which are
aligned with corresponding openings in the other female member. In
the preferred embodiment, each female member comprises three
tubular members 21-23 (see FIG. 3). The three tubular members are
mounted on the first end post 11 as by welding and are arranged
with their axes parallel to each other and parallel to the axis of
the first end post 11. In the illustrated construction, the tubular
members are preferably formed from 1 inch diameter steel tubing and
have a vertical length of about 2 inches. The lower female member
20' is of identical construction to that of female member 20, and
the foregoing description should be taken as applying to both.
The connector means also includes first and second male members 30,
30' (see FIG. 4) on the second end post 12. The male members are
vertically spaced a distance equal the spacing of the female
members 20, 20'. In the preferred embodiment illustrated, the male
member 30 is made of 5/8 inch steel rod formed into an inverted
U-shape comprising legs 31 and 32 interconnected by an intermediate
portion 33. Legs 31 and 32 are preferably parallel to each other
and mounted parallel to the axis of end post 12. The lower male
member 30' is of identical construction to that of male member 30
and the foregoing description should be taken as applying to both.
The outer legs 32 of both members 30, 30' are aligned for insertion
through the aligned openings of the female members.
Referring to FIG. 4, it can be seen that the second end post 12 may
be positioned adjacent the first end post 11 of a similar portable
fence panel 10. By raising the second end post 12, and moving it in
the direction of arrow A in FIG. 4, the male members 30, 30' may be
inserted through the selected aligned openings in the female
members 20, 20'. Since three openings are provided in the female
members, a four-way corner may be accomplished in the manner shown
in FIG. 2.
In the event that two female members end up adjacent each other as
will occur in complex configurations as shown in FIG. 1, separate
U-shaped male members can be utilized to fit into the adjacent
female members and thereby provide the connection. I prefer,
however, to provide the separate male member (not shown) in a
W-shape so that it can fit into two female members of one fence
panel and into one of the female members in each adjacent panel
thereby providing additional rigidity.
While the aforementioned structure has utility for some uses, in
accordance with the present invention the connector means also
includes a locking apparatus 40 for holding the male members 30,
30' in the inserted position. In the embodiment illustrated, the
locking apparatus 40 includes two portions which are mirror images
of each other as best shown in FIGS. 5 and 6. Each portion includes
an arcuate part 41 which is circumjacent a portion of the end post
12 and contiguous thereto, and an outwardly extending finger 42 for
underlying one of the tubular members 21-23 as best shown in FIG.
2. The two portions are held together by a fastener 43 which may be
a bolt or other means for releasably securing the circumjacent part
to the end post. When the fastener 43 is released, the locking
apparatus 40 may be moved away from its locking position either by
rotating the asme or allowing it to slide downwardly along the post
12.
It is now deemed apparent that the male members are inserted
through the female members, and the locking apparatus is disposed
at a position closely adjacent the lower end of leg 32 or the
bottom of the tubular members 21, 22 or 23, the two fence panels 10
are connected together in such a manner that they cannot be
disconnected. A mere loosening of the fastener 43 allows the
locking apparatus to be moved away from the locking position and
the fence panels can then be readily disconnected.
It is now deemed apparent from the foregoing that a series of
portable fence panels are provided which may be readily assembled
by unskilled persons with minimum effort and a minimum of time to
provide a pen or corral which will retain livestock. The fence
panel is relatively lightweight, sturdy, durable and highly
flexible as to the area enclosed.
While a preferred embodiment of the invention has herein been
illustrated and described, this has been done by way of
illustration and not limitation, and the invention should not be
limited except as required by the scope of the appended claims.
