Description
BACKGROUND OF THE INVENTION
In providing floor constructions or floors for animal enclosures
used to raise animals in confinement and using light weight channel
members, see U. S. Pat. 3,528,391, for example, it is necessary
that such floors be easy to construct and maintain, are economical,
provide adequate support for animals while assuring satisfactory
movement thereon, and allow materials such as spilled food, animal
wastes, and the like to flow easily through each floor construction
into an associated pit or tank arranged therebeneath to receive
such materials. In using channel members of the character
mentioned, it is desirable that simple and inexpensive connecting
devices or connectors be provided which will hold their associated
channel members firmly in position without the likelihood of
movement or loosening thereof even after extended use.
SUMMARY
This invention provides an improved connector in the form of a
connector-spacer which is of simple and economical construction and
an improved floor construction using such connector-spacer. The
connector-spacer is particularly adapted to hold together in spaced
parallel relation a plurality of floor-forming channel members
which have substantially vertically arranged side walls terminating
in bottom fastening flanges which extend toward each other. The
connector-spacer has a plurality of upwardly and laterally
extending fastening legs each defining a recess which is adapted to
receive an associated fastening flange therewithin and each channel
member is made of a resilient material which provides a normal
resiliency therefor and holds its fastening flanges within
associated recesses and in grasping contact against such fastening
legs. The connector-spacer has integral means retaining an
associated fastening flange of a channel member within an
associated recess to assure each member is held firmly in position
even after extended use.
Other details, uses, and advantages of this invention will become

DESCRIPTION OF ILLUSTRATED EMBODIMENTS
Reference is now made to FIG. 1 of the drawings which illustrates
an exemplary embodiment of the floor construction of this invention
which is designated generally by the reference numeral 20. The
floor construction or floor 20 is comprised of a plurality of
inverted substantially U-shaped channel members 21 which are
suitably fastened together in spaced side-by-side parallel relation
by a plurality of bottom supporting members or connector-spacers
each designated by the reference numeral 22 and each
connector-spacer 22 will be referred to hereinafter simply as a
connector 22. The floor construction 20 is particularly adapted for
use in raising animals such as poultry, swine, cattle, and the
like, in confinement, and the structural details of the components
of such floor construction and, in particular, the improved
connectors 22 will be described in detail subsequently.
As seen particularly in FIGS. 1 and 2, each channel member 21 of
this example comprises a bight 23 defining a top load-carrying wall
23 which has a pair of downwardly extending side walls 24 adjoining
opposite side edges 25 of the top wall 23. Each member 21 also has
a pair of inwardly directed fastening flanges 26 each adjoining a
lower edge 27 of an associated side wall 24 and the fastening
flanges 26 extend inwardly toward each other.
The side walls 24 of each member 21 converge downwardly from the
top wall 23 toward each other, see FIG. 2, whereby the member 21
has a width, indicated at 30, between its lower edges 27 which is
no greater than the width indicated at 31 of the top load-carrying
wall 23. The width 30 in this example is substantially less than
the width 31 whereby it will be seen that each immediately adjacent
pair of channel members 21 has a downwardly diverging passage 32
defined therebetween by an associated pair of side walls 24 and
each downwardly diverging passage 32 assures unobstructed flow of
material through the floor construction 20.
Each member 21 has non-skid means provided on its top wall 23 and
in this example such non-skid means is defined by a plurality of
upwardly extending projections or undulations 33 and each
immediately adjacent pair of projections has a recess or groove 34
arranged therebetween. However, it will be appreciated that any
suitable means may be provided on the top wall 23 to reduce the
tendency of skidding by an animal supported on the floor
construction 20.
Each connector 22 has a main body 35 (see FIGS. 1, 2, and 7) and a
plurality of upwardly and laterally extending fastening legs 36
each defining a recess 37 which is adapted to receive an associated
fastening flange 26 of a channel member 21 therein. Each connector
22 also has means retaining an associated fastening flange 26 of a
channel member 21 within an associated recess 37 and in this
example such retaining means is in the form of a bendable tab 40
defined as an integral part of the main body 35, see FIGS. 4-6.
Each channel member 21 is preferably made of a resilient metallic
material such as an aluminum alloy which provides normal resiliency
therefor and such resilient material enables the lower or bottom
end portions of the side walls 24 to be spread apart at a location
adjacent a set of fastening legs 36. This spreading action may be
accomplished using any suitable technique or tool which enables the
innermost edges 41 of a set of fastening flanges 26 to be spread
apart to a dimension wider than the dimension indicated at 42 in
FIG. 2, for example. Upon releasing the flanges 26 and side walls
24, the normal resiliency of the channel member 21 causes the
previously spread walls 24 to return to their initial positions and
with the inner end portions of the flanges 26 received within
associated recesses 37 and the flanges 26 in embracing holding
engagement against legs 36.
Once a flange 26 is in position within an associated recess, any
suitable tool such as a punch 43 may be urged against the bottom
surface 44 of an associated tab 40 forcing the tab upwardly in a
direction transverse the main body 35 of the connector 22 so that a
pair of opposed corner portions 46 comprising the tab 40 will each
engage associated side walls 24 of members 21 and hold each side
wall thus engaged firmly in position within its associated
fastening leg. Thus, even after extended use of the floor
construction 20, each member 21 is retained or firmly held in
position by its connector 22 against lateral, vertical, or rotary
movements and in properly spaced relation with other members 21
comprising the floor construction 20.
The corner portions 46 of each tab 40 are substantially rounded
having smooth arcuate configurations and each tab 40 is bent
upwardly so that its corner portions 46 are urged firmly against
side walls 24. The rounded configuration of each corner portion
assures that the outside surface of a side wall 24 engaged thereby
is kept substantially intact without deep gouges or scratches, or
other damage thereto.
Each connector 22 may have any suitable cross-sectional
configuration and in this example the connector 22 has an inverted
substantially U-shaped cross-sectional configuration comprised of a
bight which defines the main body 35 and a pair of substantially
vertically downwardly extending legs 50 adjoining opposite sides of
the main body 35. Each tab 40 is defined by providing a slit 51 in
the main body 35 with the slit having a pair of leg portions 49
which converge toward each other in a symmetrical manner to thereby
define a trapezoidal outline for the tab 40. The trapezoidal tab 40
has a base 52 which is foldably connected to and defined as an
integral part of the main body 35 and the base 52 defines the
shorter of the parallel sides of such trapezoidal tab 40 with the
longer of the parallel sides being folded upwardly away from the
main body as best seen in FIGS. 4 and 5.
It will also be noted that the outer ends of the leg portions 49 of
slit 51 have arcuate configurations each designated by the
reference numeral 53. The arcuate configurations 53 assure minimum
stress concentration upon bending the tab 40 upwardly in the manner
illustrated in FIGS. 4 and 5.
Each upwardly and laterally extending fastening leg 36 has an
undulating configuration which in this example might be considered
sinusoidal or approximately S-shaped and such undulating
configuration includes at least one downwardly convex arcuate
portion 54 which is adapted to engage and resiliently clamp an
associated fastening flange 26 firmly against the main body 35 of
the connector 22. Thus, each leg 36 not only receives and holds an
associated flange 26 in position but also serves to firmly clamp
such flange tightly against the connector.
Each connector 22 may also be provided with integral means adjacent
an end thereof to hold the outer side wall 24 of an outermost
member of a floor construction 20 in position. In this example, the
member 22 is provided with integral means in the form of a pair of
parallel slits 55 which enable a substantially rectangular portion
56 of the main body 35 to be bent upwardly as illustrated at 57 in
FIG. 1.
Another exemplary embodiment of a connector of this invention which
may be utilized to hold channel members either identical or similar
to channel members 21 used to define the floor construction 20 is
illustrated in FIGS. 8 and 9 of the drawings. The connector
illustrated in FIGS. 8-9 is very similar to the connector 22;
therefore, such connector will be designated generally by the
reference numeral 22A and parts of the connector 22A which are very
similar to corresponding parts of the connector 22 will be
designated by the same numeral as in the connector 22 also followed
by the letter designation "A" and not described again. Only those
component parts which are substantially different from
corresponding parts of the connector 22 will be designated by a new
reference numeral also followed by the letter designation "A" and
described in detail.
The connector 22A instead of having fastening legs which have a
substantially undulating configuration has roughly L-shaped
fastening legs 36A. Each leg 36A is comprised of a substantially
vertically extending portion 60A foldably connected to the main
body 35A and a substantially horizontally extending leg portion 61A
adjoining leg portion 60A and defining a recess 37A which is
laterally open.
The connector 22A also has retaining means or tabs 40A each having
a substantially rectangular outline defined by a roughly U-shaped
slit 62A through the main body 35A of the connector 22A and one of
the parallel sides of each rectangular tab 40A defines the base
52A. The rectangular tab 40A also has rounded corners 46A each
adapted to engage a side wall of an associated channel member such
as a side wall 24 of a channel member 21, for example.
The channel members 21 and connectors 22--22A may be made in any
suitable manner and from any suitable material which can be used to
provide floors for an animal enclosure substantially without
corrosion. Preferably these components are made of high strength
and light weight aluminum alloys.
In addition, it will be appreciated that the connectors 22 and 22A
may be used to hold channel members in position having various
other cross-sectional configurations. For example, such channel
members may be inverted substantially U-shaped members,
approximately E-shaped members, etc., which enable provision of a
floor construction such as the floor construction 20.
While present exemplary embodiments of this invention, and methods
of practicing the same, have been illustrated and described, it
will be recognized that this invention may be otherwise variously
embodied and practiced within the scope of the following
claims.
