Description
This invention relates to chicken coops, and more particularly to
improvements in chicken coops molded of plastic material.
Traditionally, chicken coops have been made of wood, the most
common construction including an imperforate floor, four sidewalls
constructed of a plurality of parallel vertical dowels having their
ends fixed within upper and lower elongated members, and a top
structure of similar dowel construction. In recent years, there
have been many chicken coop constructions proposed in the patented
literature and offered on the market formed of moldable plastic
material. In general, these prior art plastic chicken coops have
been constructed utilizing conventional thin, perforated ribbed
walls in the structural components of the chicken coop. The
utilization of this conventional formation, particularly in the
side wall structure of the chicken coop, has not proven entirely
satisfactory. A perforated and ribbed thin wall construction in the
sidewalls of a chicken coop does not provide the chicken coop with
both the strength and ventilation necessary. Where the perforations
are made large enough to provide adequate ventilation, the strength
characteristics are detrimentally affected. And conversely, where
sufficient strength is built into the sidewall structure, adequate
ventilation has not been provided. From a point of view of the
strength provided in prior art plastic chicken coops, one common
failure occurs when the chicken coops are loaded in stack formation
on a truck. The usual practice is to tie the stack formation onto
the truck by straps, or the like. The straps contacting the
uppermost coop in the stack frequently resulted in the collapse of
the sidewalls.
It is an object of the present invention to provide a molded
plastic chicken coop construction having sidewalls formed of
integral elongated elements similar to the dowels utilized in
wooden chicken coops, the construction affording all of the
advantages of strength and adequate ventilation heretofore provided
in wooden chicken coops and eliminating the disadvantages that have
existed in the chicken coops of plastic material heretofore
proposed.
Another object of the present invention is the provision of a
chicken coop of the type described having stacking elements formed
adjacent the top and bottom peripheries thereof which not only
perform the function of stably supporting a plurality of chicken
coops in vertically stacked formation, but, in addition, provide
added strength to resist the tie-down stresses imposed during
transportation, particularly with respect to the uppermost chicken
coop of the stack formation, as aforesaid.
Still another object of the present invention is the provision of a
chicken coop molded of plastic material presenting relatively
smooth inside surfaces devoid of sharp edges, thus minimizing
damage to the chickens contained therein while providing
essentially non-skid upper and lower surface configurations, thus
reducing the hazards to personnel climbing on the chicken coops in
the formation of transportation stack loads.
Still another object of the present invention is the provision of a
chicken coop construction molded of a foamed plastic material so as
to be of minimum weight while at the same time having sufficient
strength to provide a durable life under normal operating
conditions.
Still another object of the present invention is the provision of a
chicken coop molded of plastic material which is simple in
construction, effective in operation and economical to
manufacture.
These and other objects of the present invention will become more
apparent during the course of the following detailed description
and appended claims.
The invention may best be understood with reference to the
accompanying drawings, wherein an illustrative embodiment is
shown.

principles of the present invention;
FIG. 2 is a top plan view of the chicken coop shown in FIG. 1;
FIG. 3 is a sectional view taken along the line 3--3 of FIG. 2;
FIG. 4 is a fragmentary top plan view showing a corner of the
bottom part of the chicken coop;

line 7--7 of FIG. 2; and
FIG. 8 is a fragmentary sectional view taken along the line 8--8 of
FIG. 2 showing two chicken coops in vertically stacked
relation.
Referring now more particularly to the drawings, there is shown in
FIGS. 1 and 2 thereof a chicken coop, generally indicated at 10,
embodying the principles of the present invention. In general, the
chicken coop 10 includes a generally horizontally extending bottom
structure, generally indicated at 12, which is of generally
rectangular configuration in plan, a generally horizontally
extending top structure, generally indicated at 14, which is of
generally similar rectangular configuration in plan, and a
four-sided peripheral wall structure, generally indicated at 16,
which extends vertically between the periphery of the bottom
structure 12 and the periphery of the top structure 14. In
accordance with the principles of the present invention, the
chicken coop 10 is molded of plastic material. The plastic material
utilized may be of any of the well-known types, and preferably the
material is utilized in a foamed condition. The preferred plastic
material is foamed polyethylene. In the preferred embodiment shown,
the chicken coop 10 is molded in essentially two parts, the bottom
structure 12 being molded integrally with the peripheral wall
structure 16 to form one part and the top structure 14 being molded
separately. It will be understood, however, that the peripheral
wall structure 16 may be molded integrally with the top structure
14 and the bottom structure 12 molded separately.
Referring now ore particularly to FIGS. 3 and 4, the bottom
structure 12 includes a perforated floor portion 18, the
perforations preferably being in the form of a multiplicity of
rectangular openings 20 disposed with their sides at 45.degree.
angles with respect to the sides of the bottom structure. As best
shown in FIG. 6, the plastic material defining the openings has a
generally T-shaped cross-sectional configuration, the upper edges
defining the openings being rounded off, as indicated at 22 and the
lower edges being sharp as indicated at 23. It will be understood
that the openings 20 adjacent the periphery of the floor portion 18
are of generally triangular configuration, thereby forming a
continuous imperforated peripheral portion 24 surrounding the
perforate floor portion 18. Extending downwardly from the
peripheral portion 24 in slightly inwardly spaced relation to the
peripheral edge thereof is an integral stacking ring 26 which, as
shown, is of rectangular configuration in plan, as well as in
cross-section.
The peripheral wall structure 16 includes a plurality of
horizontally spaced vertically coextensive elongated elements 28
having their lower ends integrally joined with the peripheral
portion 24 of the bottom structure 12. As best shown in FIG. 3,
each of the elongated elements 28, with the exception of the corner
elements is formed so as to provide inner portions of generally
semicircular cross-sectional configuration and outer portions of
generally semi-elliptical cross-sectional configuration. The extent
of the inner portions measured in the direction of extent of the
adjacent peripheral portion 30 constitutes the maximum thickness of
the elongated elements, and the thickness in the direction
perpendicular thereto is at least as great, and preferably greater,
as shown with the major axis of the semi-elliptical portion
extending in that direction. The corner elongated elements 28 have
a cross-sectional configuration conforming to the cross-sectional
configuration which would be derived by fusing two elongated
elements together at right angles with respect to each other and
rounding off the peripheral surfaces of the inner portions to
provide a smooth contour.
The upper ends of the elongated elements are integrally connected
with a continuous upper peripheral portion 30 disposed in generally
parallel relation with the peripheral portion 24. As shown, the
peripheral portion 30 is of generally rectangular cross-sectional
configuration and is integrally connected with the upper ends of
the elongated elements 28, with the inner portions of the latter
extending inwardly of the peripheral portion 30. The inwardly
extending relationship of the inner portions of the elongated
elements, at least in the area adjacent their interconnection with
the peripheral portion 30, is an essential feature of the present
invention in that it provides smooth interior surfaces on the
elongated elements while at the same time providing sufficient
integral strength.
Referring now more particularly to FIGS. 3 and 5, the top structure
14 includes a peripheral portion 32 of inverted U-shaped or channel
configuration in cross-section. The inner wall of the inner flange
or leg of the peripheral portion 32 is formed with a plurality of
annularly spaced semicircular recesses 34 which are adapted to
receive the upper ends of the inner portions of the elongated
elements 28 which are coextensive with the peripheral portion 30,
when the latter is received within the channel-shaped peripheral
portion 32.
In accordance with the principles of the present invention, means
is provided for fixedly securing the peripheral portion 30 with the
peripheral portion 32. While suitable means may be utilized to
effect this rigid securement, in the preferred embodiment shown,
the central interior surface of the bight of the peripheral portion
32 is formed with a small annular starter bead 35 which serves to
weld or fuse the two parts of the chicken coop together when sonic
welded in accordance with conventional practice.
The top structure 14 also includes a perforated top wall or roof
portion 36 which is integrally connected with the peripheral
portion 32 adjacent the lower end of the inner flange or leg
thereof. The roof portion 36 is formed with an access opening 38 of
generally rectangular configuration which, as shown, preferably
extends substantially across the top structure 14 between two
opposed sides thereof in one direction and withon one-half of the
extent between the other two opposed sides of the top structure.
The access opening 38 is of a size to permit a plurality of
chickens to be loaded therethrough at the same time. Such size is
desirable in that it is a conventional practice for chickens to be
loaded into chicken coops by an operator holding a number of
chickens in each hand.
The remaining area of the roof portion is provided with
perforations in the form of openings 40, again of generally
rectangular configuration, disposed with their sides at 45.degree.
angles with the sides of the top structure 14. As best shown in
FIG. 7, the plastic defining the openings 14 is of generally
U-shaped configuration, presenting a smooth interior surface and
providing relatively sharp edges, indicated at 42, on the exterior.
The sharp edges 42 have the functional advantage of providing a
non-skid exterior top surface on the chicken coop 10. Such non-skid
surface is desirable since, during the normal use of a chicken
coop, when a plurality are being mounted in stacked relation on a
truck bed or the like, the operator has occasion to step on the
upper surfaces of the coops. An antiskid surface is of particular
importance where the material from which the chicken coop is
constructed is plastic because of its otherwise waxy or slippery
nature.
The chicken coop 10 of the present invention, like all conventional
constructions, includes means for opening and closing the access
opening 38. In the preferred embodiment shown, this means takes the
form of a sliding perforated door 44. The perforations of the door
are preferably constructed similarly to the openings 40. The door
44 is retained on the top structure 14 for sliding movement between
open and closed positions by a pair of horizontal flanges 46
extending inwardly along opposite sides of the top structure 14
from the upper interior surface of the channel-shaped peripheral
portion 32. The door is mounted beneath the flanges 46 by manually
flexing the same until the associated ends enter therebelow. Any
suitable means may be provided for releasably retaining the door 44
in its closed position. In the preferred embodiment shown, the
means takes the form of a pair of recesses 47 formed in the sides
of the door, and a pair of ribs 48 formed in the top structure 14
at positions to engage within the recesses 47 when the door is
disposed in its closed position.
The area of the roof portion 36 extending between the access
opening 38 and the adjacent openings 40 is preferably strengthened
by an elongated strengthening rib 50 extending across the top
structure in depending relation. The top structure 14 also includes
an integral stacking ring 52 extending upwardly from the outer
peripheral edge of the channel-shaped peripheral portion 32. As
best shown in FIG. 8, the stacking ring 52 is complementary with
the stacking ring 26, permitting a plurality of like chicken coops
10 to be stably mounted in vertically stacked relation one on top
of the other. In this regard, it will be noted that the upwardly
facing surface of the upper stacking ring 52 of the lower coop 10
engages the downwardly facing surface of the peripheral portion 24
extending outwardly of the lower stacking ring 26 of the upper coop
10, while the lower surface of the upper stacking ring engages the
upper surface of the channel-shaped peripheral portion 32. The
outer peripheral surface of the lower ring thus engages within the
inner peripheral surface of the upper stacking ring so as to
effectively prevent relative horizontal movement between the two
coops and thereby provide horizontal stability to the stack
formation.
It will be noted that the lower stacking ring 26 serves as a
supporting means for the chicken coop whether disposed in a stack
formation or on a horizontal surface. The perforated floor portion
18 is consequently free of direct horizontal support and thus has a
desirable degree of resiliency which materially aids in handling
the chickens. The upper stacking ring 52, in addition to providing
a stable stacking function, serves as a strengthening rib tending
to prevent collapse of the peripheral wall structure 16 when the
coop 10 constitutes the uppermost coop of a vertical stack and
receives the tie-down straps or the like for retaining the stack of
coops on an open-bed truck or the like. For the reasons set forth
above a continuous full periphery stacking ring construction as
shown is preferred, although it will be understood that the above
advantages can be obtained with parallel elongated stacking
elements extending along two opposite sides.
It can thus be seen that there has been provided a chicken coop 10
molded of a foamed plastic material which is light in weight and
yet provides both adequate strength and adequate ventilation. When
a plurality of coops constructed in accordance with the present
invention are disposed in vertically stacked relation, there is
adequate ventilation through the peripheral wall construction.
While the bottom of the floor portion of the coop can be formed of
imperforate construction, the perforated construction shown is
preferred since this construction provides for vertical flow of
ventilating air through the stack of coops as well as horizontal
flow through the peripheral wall structure 16. The coop 10 of the
present invention provides smooth interior surfaces, minimizing
damage to the chickens, while at the same time being provided with
nonskid upper and lower surfaces through the provision of the sharp
edges 23 and 42.
It thus will be seen that the objects of this invention have been
fully and effectively accomplished. It will be realized, however,
that the foregoing preferred specific embodiment has been shown and
described for the purpose of illustrating the functional and
structural principles of this invention and is subject to change
without departure from such principles. Therefore, this invention
includes all modifications encompassed within the spirit and scope
of the following claims.
