CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of US Provisional Patent Application 61/438,941, filed on 02/02/201 1, and US Non-Provisional Utility Patent Application 13/356,279, filed on 01/23/2012, both incorporated herein by reference.

FIELD OF THE INVENTION

This invention relates to rodent traps, and more particularly to a rodent bait station.

DISCUSSION OF RELATED ART

Rodent bait stations of the prior art suffer from several important drawbacks.

Namely, many such prior art bait stations allow water entering the enclosure to contact the bait, thereby ruining the bait. Such prior art bait stations do not facilitate the draining of such water therefrom. Further, prior art bait stations make no provision for eliminating snails, slugs, crickets, and other insects before such can soil the rodent bait, making it less attractive to rodents. Prior art bait stations are not easily anchored in place, and do not provide sufficient gripping points for adhesives when used therewith. Such prior art stations are not thermally insulated to keep rodent bait from drying out and flaking off of suspension rods that hold such bait in an attractive position for rodents. Further, such prior art stations have covers fixed with a living hinge to an enclosure that, after repeated use, become worn and fail.

Therefore, there is a need for a device that prevents water from entering the enclosure in a way that will ruin the rodent bait used therein, and that will provide ample drainage for any water that does enter the enclosure. The needed device would facilitate anchoring thereof in several versatile configurations, and would provide means for preventing insects, snails, and other vermin from contacting and soiling the rodent bait. The needed invention would be durable and the cover of such a device would include a robust living hinge. The present invention accomplishes these objectives.

SUMMARY OF THE INVENTION

The present device is a rodent bait station for placing on a ground surface, and optionally also up against a wall surface. An enclosure has a pair of side walls that each have a rodent aperture therein, a bottom wall, at last one top wall, a rear wall, and an open front side. The bottom wall includes a plurality of drain apertures therein, each further including a selectively removable protective cover, such that adhesive applied to the bottom wall does not occlude the drain aperture. The enclosure may further include a cement board attached to the outside of the bottom wall allowing the rodent bait station to be attached to the ground surface using a mortar type material.

A front cover is adapted for sealing the open front side of the enclosure. Preferably the front cover is fixed to the bottom wall of the enclosure with a living hinge. The enclosure includes at least one cover locking mechanism cooperative with the cover to secure the cover over the open front side of the enclosure.

A rigid bait platform is contained within the enclosure and comprises a pair of risers supporting a mezzanine and defining an anchor space therebetween for receiving a brick or other suitably weighted object. The mezzanine includes a bait receptacle thereon.

In one embodiment, a bait hanging mechanism comprises a first bracket fixed to the rear wall between the mezzanine and the at least one top wall. The bait hanging mechanism further includes a second bracket fixed to the front cover, and at least one bait hanging rod selectively positionable on the first and second brackets, whereby bait dropping from the bait hanging rod falls into the bait receptacle.

A pair of insecticide trays may be formed on the mezzanine on opposing sides of the bait receptacle for filling with a suitable insecticide for keeping crickets and other insects from accessing and spoiling the rodent bait. Similarly, a pair of snail bait trays may be formed on the bottom wall between each side wall and riser for filling with a suitable mollusk poison for keeping snails and slugs from accessing and spoiling the rodent bait. In use, with rodent bait placed into the bait receptacle or onto the bait hanging rod, a rodent may enter the enclosure through one of the side walls thereof, climb up one of the risers and onto the mezzanine to access the rodent bait. The poisoned rodent may then crawl down the other side of the mezzanine and riser to exit the enclosure at the opposing side rodent aperture.

The present invention is a rodent bait station that prevents water from entering the enclosure in a way that will ruin the rodent bait used therein. The present device provides ample drainage for any water that does enter the enclosure. The present invention facilitates anchoring of the bait station in several versatile configurations, and provides means for preventing insects, snails, and other vermin from contacting and soiling the rodent bait. The present invention is durable and the cover of such a device includes a robust double living hinge. Other features and advantages of the present invention will become apparent from the following more detailed description, taken in conjunction with the accompanying drawings, which illustrate, by way of example, the principles of the invention.

Words using the singular or plural number also include the plural or singular number respectively. Additionally, the words "herein," "above," "below" and words of similar import, when used in this application, shall refer to this application as a whole and not to any particular portions of this application. When the claims use the word "or" in reference to a list of two or more items, that word covers all of the following interpretations of the word: any of the items in the list, all of the items in the list and any combination of the items in the list.

FIGS. 1 and 7 illustrate a rodent bait station 10 for placing on a ground surface 15, and optionally also up against a wall surface 16 (FIG. 13). An enclosure 20 has a pair of side walls 230 that each have a rodent aperture 40 therein (FIGS. 1 and 5), a bottom wall 50, at last one top wall 20, a rear wall 240, and an open front side 250 (FIG. 7). The bottom wall 50 includes a plurality of drain apertures 100 (FIG. 7) therein so that water entering the enclosure 20 may drain therethrough. The rear wall 240 may include a rodent attractant tray 150 (FIG. 10) projecting into the enclosure 20 for retaining a rodent attractant (not shown) therein. An anchor aperture 1 10 may be further included through the bottom wall 50 of the enclosure 20, the anchor aperture 1 10 being of a larger diameter than any of the drain apertures 100 for receiving a mechanical anchor (not shown) for anchoring the bait station 10 onto a dirt or grass ground surface 15.

Each drain aperture 100 may further include a selectively removable protective arcuate cover 180 (FIGS. 7 and 11), such that adhesive applied to the bottom wall 50 does not occlude each drain aperture 100. As such, water may drain through each drain aperture 100 and through the protective cover 180.

The bottom wall 50 and rear wall 240 may each include a plurality of T-shaped standoffs 170 projecting away therefrom outside of the enclosure 20, such that adhesive applied to the bottom wall 50 and side wall 240 may form strong, permanent bonds therewith (FIGS. 7, 12, and 13). Also, the plurality of T-shaped standoffs 170 acts to keep adhesive applied to the bottom wall 50 from occluding each drain aperture 100. Furthermore, the plurality of T-shaped standoffs 170 also acts to keep adhesive applied to side walls 230 from occluding ventilation apertures 160.

In another embodiment, the rodent bait station 10 may further include a cement board 400 (FIG. 15) attached to the bottom wall 50 outside of the enclosure 20. Preferably, the cement board 400 has the approximate same width and length of the bottom wall 50. The cement board 400 may be attached to the enclosure 20 using at least one screw and nut set 405 (FIG. 15) via the anchor aperture 1 10, though other appropriate attachment methods may be used. In one embodiment, the cement board 400 may be secured to the ground surface 15 using mortar 410 (FIG. 15), thought other suitable materials may be used. Preferably, a thinset mortar is used to secure the rodent bait station 10 to the ground surface 15.

The side walls 230 may further include ventilation apertures 160 (FIGS. 12—13) to allow hot air inside the enclosure 20 to escape therethrough. Further in FIGS. 1 and 12, each of the at least one top wall 20 includes a pair of opposing insulator panel slots 350, such that an insulator panel 70 may be slidably retained therein to insulate the inside of the enclosure 20 from ambient heat, such as caused by sunlight exposure on the at least one top wall 20.

In FIGS. 1 and 7, a front cover 30 is adapted for sealing the open front side 250 of the enclosure 20. Preferably the front cover 30 is fixed at a lower edge 31 (FIG. 5) thereof to the bottom wall 50 of the enclosure 20 with a living hinge 340 (FIG. 14), and preferably a double living hinge 342 (FIG. 14). The cover 30 includes an outside surface 34 and an inside surface 32 (FIGS. 2—5). Preferably the enclosure 20 and cover 30 are integrally formed from injection molded plastic materials, for example.

In one embodiment illustrated in FIGS. 1 and 12, the enclosure 20 includes at least one cover locking mechanism 220 cooperative with the cover 30 to secure the cover 30 over the open front side 250 of the enclosure 20. Preferably a portion 200 (FIG. 1) of the cover 30 interlocks with a front edge 255 (FIG. 1) of the enclosure 20 to create a water resistant seal. Each cover locking mechanism 220 preferably includes an aperture 120 (FIGS. 1 and 4) through which a key or other particularly-shaped object (not shown) may be inserted to release the cover locking mechanism 220 to free the cover 30 from the enclosure 20. A cover 130 on a pivot screw 140 (FIGS. 7 and 8) may be included to cover each aperture 120 to prevent rain from entering the enclosure therethrough.

In FIGS. 1 and 12, a rigid bait platform 60 is contained within the enclosure 20 and comprises a pair of risers 260 supporting a mezzanine 270 and defining an anchor space 275 therebetween for receiving a brick 210 or other suitable weighty object, such as a concrete block or metal ingot. In FIGS. 1 and 7, the risers 260 and the mezzanine 270 extend from the rear wall 240 to the open front side 250 so as to isolate the anchor space 275 from the rest of the space within the enclosure 20 when the cover 30 is sealed over the front side 250 of the enclosure 20. The mezzanine includes a bait receptacle 280 (FIG. 7) thereon. The bait platform 60 may be made from a rigid plastic material, and is preferably integrally formed with the enclosure 20 and the cover 30.

In one embodiment in FIG. 7, a bait hanging mechanism 290 (FIG. 12) comprises a first bracket 155 (FIG. 10) fixed to the rear wall 240 between the mezzanine 270 and the at least one top wall 20. The bait hanging mechanism 290 further includes a second bracket 90 (FIG. 9) fixed to the front cover 30, and at least one bait hanging rod 300 (FIG. 9) selectively positionable on the first and second brackets 155,90, whereby bait 18 dropping from the bait hanging rod 300 falls into the bait receptacle 280. Such a bait 18 may be similar to that sold under the brand name Contrac Blox, manufactured by Bell Laboratories, Inc. of Madison, Wisconsin, for example. The bait receptacle 280 may also be filled partially with a suitable tracking powder (not shown), such as that sold by Bell Laboratories, Inc. of Madison, Wisconsin, under the brand name Ditrac. In FIGS. 1 and 7, a pair of insecticide trays 310 may be formed on the mezzanine 270 on opposing sides of the bait receptacle 280. Such insecticide trays 310 may be filled with a suitable insecticide (not shown) for keeping crickets and other insects from accessing and spoiling the rodent bait 18. Similarly, a pair of snail bait trays 320 (FIG. 12) may be formed on the bottom wall 50 between each side wall 230 and riser 260. Such snail bait trays 320 may be filled with a suitable mollusk poison for keeping snails and slugs from accessing and spoiling the rodent bait 18. A copper ring 330 (FIG. 13) may further be included, fixed around each rodent aperture 40 to inhibit snails and slugs from entering the enclosure 20.

In one embodiment the at least one top wall 20 includes exactly two top walls 20 fixed at a top central point 370, each of the two top walls 20 sloping downwardly to overhang one of the side walls 240 (FIGS. 12 and 13). Alternately, the at least one top wall 20 includes exactly three top walls 20, one of which is a top-most horizontal top wall 380 (FIG. 7) fixed to each of the other two top walls 390 that each slope down to one of the side walls 240 (FIGS. 1--7).

In use, with rodent bait 18 placed into the bait receptacle 280 or onto the bait hanging rod 300, a rodent (not shown) may enter the enclosure 20 through one of the side walls 230 thereof, climb up one of the risers 260 and onto the mezzanine 27 to access the rodent bait 18. The rodent may then crawl down the other side of the mezzanine 270 and riser 260 to exit the enclosure 20 at the opposing side rodent aperture 40. While a particular form of the invention has been illustrated and described, it will be apparent that various modifications can be made without departing from the spirit and scope of the invention. For example, an embodiment of the bait station 10 having two top walls 20, and another embodiment having three of the top walls 20, are illustrated, but other configurations could be devised.
