Description
FIELD OF THE INVENTION
[0001] This invention relates to methods, apparatus, and assemblies
for termite control and extermination. More particularly, this
invention relates to such methods and assemblies which include and
use ground termite monitoring stations.
BACKGROUND OF THE INVENTION
[0002] Commonly known assemblies for termite control through ground
monitoring comprise multiple cylindrical housings, each having
termite access ports or apertures, a lid for covering the housing,
and a wooden bait stick for insertion into and retention within the
housing. In use of such assemblies, cylindrical holes are dug
within the ground, typically by augering, the holes being
positioned around the periphery of a building to be protected.
Thereafter, the cylindrical housings are downwardly inserted into
the holes, wooden bait sticks are downwardly inserted into the
hollow interior spaces of the cylindrical housings, and lids are
attached to the housings, covering the bait sticks within the
housings' interior spaces. Thereafter, an operator of the system,
typically a pest control company employee, periodically returns to
the building for inspection of the bait sticks for evidence of
termite activity.
[0003] A problem or deficiency related to such common termite
ground monitoring, baiting, and exterminating systems is that the
operator must repeatedly stoop or kneel to ground level for
monitoring station installations and for bait stick inspections,
resulting in heightened levels of back strain injuries within the
pest control company's work force.
[0004] The instant inventive assembly and method for termite ground
monitoring and baiting solves or ameliorates the problems discussed
above by providing ergonomic termite monitoring and baiting station
components and method steps which allow for monitoring station
installations and bait stick inspections from a standing position
and without repeated stooping to ground level.
BRIEF SUMMARY OF THE INVENTION
[0005] A primary structural component of the assembly of the
instant invention comprises an upwardly opening cylindrical housing
having a side wall which defines a hollow interior space. The side
wall preferably has a plurality of termite access ports allowing
lateral passage of termites from an exterior ground environment,
through the access ports, and into the hollow interior space of the
cylindrical housing. Also preferably, the cylindrical housing
further opens downwardly, facilitating insertion from below of
termite bait sticks and further allowing upward access by termites
to the interior space defined by the cylindrical housing. While the
assembly of the instant invention may suitably comprise as few as a
single or a first rendition of such cylindrical housing, the
assembly preferably comprises a plurality of second similarly
configured housings, the plurality being of a number sufficient for
even intermittent spacing within the ground around the periphery of
a building to be protected by the monitoring system.
[0006] A further structural component of the assembly of the
instant invention comprises a lid which is fitted for covering the
upper opening of the cylindrical housing. Preferably, removable lid
attaching means are provided for removably connecting the lid to
the cylindrical housing. Preferably, such removable lid attaching
means is molded integrally with the lid and integrally with the
upper lip of the cylindrical housing, such means preferably
comprising a rotating slotted flange and "L" hook combination.
Suitably, other removable attaching means may be utilized such as
snap ridge and snap channel combinations, snap lug and snap
apertures combinations, intermeshing helical threads, mechanical
latches, velour crochet pads, and adhesive pads. Numerous other
commonly known removable attaching means may similarly be suitably
substituted for the preferred "L" hook and rotating slotted flange
combination. Where the preferred plurality of cylindrical housings
is provided, a matching plurality of lids is similarly provided,
the removable lid attaching means further interconnecting the
multiple lids and the multiple cylindrical housings.
[0007] A further structural component of the assembly of the
instant invention comprises a bait stick cradle. Necessarily, the
bait stick cradle is fitted for downward insertion into the
interior space of the cylindrical housing. Preferably, the bait
stick cradle has a removable floor and preferably, floor attaching
means are provided, such means being adapted for removably
connecting the floor to the bait stick cradle. Where the assembly
comprises a removable floor and floor attaching means combination,
removal of the floor allows a termite bait stick to be inserted
upwardly into the bait stick cradle. Regardless of the removability
of the floor of the cradle, the floor preferably partially closes
the lower end of the bait stick cradle, allowing downward drainage
of water and upward termite bait stick access. Preferably, the
floor of the bait stick cradle comprises a plastic dowel, and
preferably the floor attaching means comprises dowel receiving snap
channels or "C" channels which are molded into the lower ends of
the walls of the bait stick cradle, such channels holding the dowel
in a position spanning across the lower end of the bait stick
cradle. Suitably, the preferably removable bait stick cradle floor
may alternately comprise an apertured disk or plate and the floor
attaching means may alternately comprise removable attaching means
similar to those described above for attaching the lid to the upper
end of the cylindrical housing. Where the inventive assembly
comprises, as preferred, pluralities of cylindrical housings and
lids, a plurality of bait stick cradles with attachable and
detachable floors is preferably similarly provided.
[0008] Means for suspending and downwardly extending the bait stick
cradle below and from the lid are necessarily provided, such means
preferably comprising at least a first, and preferably a pair of
rigid ties interconnecting the bait stick cradle and the lid. Other
means for suspending and downwardly extending the bait stick cradle
below the lid, such as flexible cords, chains, or ties may be
suitably substituted for the preferred rigid ties.
[0009] A further preferred component of the assembly of the instant
invention preferably comprises an extension arm, preferably having
a length equal to the waist height of a system operator.
Preferably, the extension arm comprises an upper handle means such
as a "T" handle or knob, and the lower end of the extension arm
necessarily forms extension arm attaching means adapted for
successive removable attachments to the lids described above.
Preferably, the extension arm attaching means comprises, in
combination with structure integral with the upper surfaces of the
lids, a friction slot and friction tab or flange combination. Other
removable attaching means such as snap channel and snap ridge
combinations, snap lug, and snap aperture combinations,
intermeshing helical threads, and key and key aperture combinations
may be suitably alternately utilized as the extension arm attaching
means. Numerous other commonly known removable attaching means may
be also suitably substituted.
[0010] According to the method of the instant invention, and
assuming that a plurality of monitoring station assemblies as
described above are provided, cylindrical holes are augered
peripherally around a building to be protected by the system.
Preferably, an augering machine of the type which is operable from
a standing position is utilized for augering such holes, and
preferably, the holes are fitted for receiving the outside
diameters and vertical heights of the cylindrical housings.
[0011] Prior to or following the monitoring station holes augering
steps, termite monitoring stations, including components configured
as described above, are assembled to include a termite bait stick
carried by a bait stick cradle suspended from a lid, the cradle and
bait stick assembly extending downwardly from the lid and into the
hollow interior space of the cylindrical housing. In such
configuration, the lid attaching means preferably holds the lid
upon the cylindrical housing, and holds the bait stick cradle and
bait stick within the cylindrical housing's interior space.
Following assemblies of such monitoring station components, the
cylindrical housings are successively embedded within the ground by
inserting them into the monitoring station holes. For prevention of
bending or stooping in such insertions steps, the extension arm is
preferably utilized for downwardly extending and inserting the
assembled monitoring stations into the monitoring station
holes.
[0012] Typically, the termite monitoring stations are allowed to
remain within the ground undisturbed for approximately one month,
at which time an operator of the system returns to inspect the bait
sticks which are housed within the embedded stations. In order to
inspect the bait sticks without stooping or bending, the operator
preferably utilizes the extension arm to disengage the lid
attaching means of the monitoring stations, and to upwardly retract
the lids, bait stick cradles, and carried bait sticks for visual
inspections. Thereafter, the extension arm may be utilized for
re-assembly of the stations within the ground without stooping to
ground level.
[0013] Accordingly, objects of the instant inventive assembly and
method comprise providing a termite monitoring station having a lid
and having a downwardly extending bait stick carrying cradle, such
lid facilitating ease of insertion and retrieval of bait
sticks.
[0014] It is a further object of said invention to provide
structure, implements, and method steps integral with or associated
with the inventive monitoring station and allowing for bait
monitoring station installations and subsequent bait stick
inspections without bending or stooping to ground level.
[0015] Other and further objects, benefits, and advantages of the
present invention will become known to those skilled in the art
upon review of the Detailed Description which follows, and upon
review of the appended drawings.

DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT
[0019] Referring now to the drawings, and in particular to FIG. 1,
the termite monitoring station of the assembly of the instant
invention is referred to generally by Reference Arrow 1. The
monitoring station 1 comprises a cylindrical housing 2 having at
least a plurality of, and preferably a multiplicity of termite
access ports 4. Referring simultaneously to FIGS. 1 and 2, the
cylindrical housing 2 preferably has a hollow interior space 8
which opens upwardly and, preferably, has a lower opening 6. The
upper lip of the cylindrical housing 2 preferably comprises an
outwardly extending annular ground engaging flange 10. The upper
surface of flange 10 preferably forms an annular lid receiving and
centering ridge 12, said ridge 12 supporting a pair of radially
opposed lid retaining "L" hooks 14 and 16.
[0020] Referring simultaneously to FIGS. 1, 2, and 3, a bait stick
cradle and lid combination is referred to generally by Reference
Arrow 25, such combination preferably comprising a lid 32, a bait
stick cradle 24, and a pair of rigid ties 18 extending downwardly
from the lid 32, and interconnecting the bait stick cradle 24 with
the lid 32. Preferably, the rigid ties 18 form and define laterally
opening termite access ports 20 and 21. Also preferably, upper ends
of ties 18 form and define a hollow cylindrical space 26, such
space functioning to retain bait stick 60 in its upright position.
Also preferably, the lower end of bait stick cradle 24 forms "C"
clip channels 28 for receipt of and for removable attachment of a
dowel rod 30. The dowel rod 30 serves as a floor of bait stick
cradle 24, the dowel rod 30 retaining a bait stick 60 below lid 10,
while providing for downward drainage of water, and upward termite
access. Preferably, the outside diameter of the lid 32 is fitted
for nesting receipt within the inside diameter of ridge 12. Also
preferably, the lid 32 is molded to include a cylindrical upwardly
opening cavity 34, such cavity 34 having a flange or wall 40
spanning thereacross, the flange or wall 40 serving as a removable
attaching means for alternate connection to and detachment from an
extension arm which is referred to generally by Reference Arrow
50.
[0021] Referring simultaneously to FIGS. 1 and 2, the vertical
thickness of lid 32 is slightly less than the vertical height of
"L" hooks 14 and 16, allowing lid 32 to slidably rotate beneath "L"
hooks 14 and 16. Lid 32 has slots 36 and 38 for alternate
engagement and disengagement of lid 32 with and from flange 10.
Upon rotation of lid 32 90.degree. from the position depicted in
FIG. 1, slots 36 and 38 respectively underlie "L" hooks 14 and 16.
In such position, lid 32, along with underlying cradle 24, may be
freely inserted into and withdrawn from the interior space 8 of the
cylindrical housing 2. Upon rotation of lid 32 to the orientation
depicted in FIG. 1, "L" hooks 14 and 16 effectively retain the lid
32 and the underlying cradle 24 within space 8.
[0022] Referring simultaneously to FIGS. 2 and 3, extension arm 50
preferably has a shaft 52 having a length equal to waist height, a
"T" handle, and an enlarged foot 56, the foot 56 having a slot 58.
The dimensions of slot 58 are preferably closely fitted to the
dimensions of flange 40, allowing the foot 56 in combination with
flange 40 to serve as a removable lid attaching means.
[0023] In use of the assembly depicted in FIGS. 1-3, an augering
machine (not depicted) is preferably utilized for augering a
monitoring station hole 64 within ground material 62. Preferably,
such augering machine is operable from a standing position without
bending or stooping. Thereafter, or alternately preliminarily, the
lid and bait stick cradle combination 25 is secured within
cylindrical housing 2, and bait stick 60 is secured within space 26
to rest upon dowel rod 30. In commercial packaging and use of
multiple renditions of the monitoring station 1, such station is
preferably shipped upside down within a box (not depicted), and in
the latched configuration depicted in FIG. 1. In such shipping
configuration, lower ends of bait stick cradles 24 are exposed
within the opening of such box, allowing an operator to remove
dowels 30, insert bait sticks 60 through the opened lower cradle
ends, and to replace dowels 30. In such configuration, such box may
be held upon a portable waist height working stand in close
proximity with monitoring station holes 64 augered within the
ground. Thereafter, an operator, while grasping extension arm 50 in
one hand, may retrieve from such box with his other hand a termite
monitoring station 1. Thereafter, the operator may manually align
slot 58 of foot 56 with flange 40, and compressively drive slot 58
over slot 40, connecting the lid and bait stick cradle combination
25, the bait stick 60, and the cylindrical housing 2 to the lower
end of the extension arm 50. Thereafter, the operator may release
the monitoring station 1, allowing the monitoring station 1 to
suspend from the lower end of the extension arm 50. Thereafter, the
operator may utilize the extension arm 50 to downwardly extend and
direct the monitoring station 1 into the monitoring station hole
64, embedding the monitoring station 1 within the ground without
stooping. Thereafter, the operator may place a foot upon exposed
upper surfaces of the lid 32 or of the flange 10, and upwardly pull
the extension arm 50, disengaging slot 58 from flange 40.
Repetition of the procedure described above allows the operator to
embed numerous renditions of monitoring station 1 within the ground
62 without bending or stooping to ground level.
[0024] Upon departure and subsequent return of the operator to the
monitoring station site (typically weeks later), the operator may
downwardly extend extension arm 50, aligning slot 58 of foot 56
with flange 40, and downwardly drive slot 58 over flange 40,
engaging the lower end of extension arm 50 with lid 32. Thereafter,
the operator may rotate "T" handle 54 90.degree., rotating lid 32
90.degree., and aligning slots 36 and 38 with "L" hooks 14 and 16.
Thereafter, the operator may upwardly raise the extension arm 50
along with the lid and bait stick cradle combination 25, such
combination carrying bait stick 60. Upon raising the lid and bait
stick cradle combination 25 to eye level, the operator may view the
bait stick 60 through port 20 or through 21 to determine whether
termites have begun to feed upon bait stick 60. Thereafter, the lid
and bait stick cradle combination 25, along with bait stick 60, or
a replacement insecticide carrying bait stick (not depicted), may
be returned to its original position within cylindrical housing 2,
and without stooping, through a reversal of the steps described
above. Through repetition of the bait stick inspection procedure
described above, an operator may inspect several monitoring
stations without stooping or bending to ground level.
[0025] While the principles of the invention have been made clear
in the above illustrative embodiment, those skilled in the art may
make modifications in the structure, arrangement, portions,
components, and method steps of the invention without departing
from those principles. Accordingly, it is intended that the
description and drawings be interpreted as illustrative and not in
the limiting sense, and that the invention be given a scope
commensurate with the appended claims.
