The present invention relates generally to pest control products and, more particularly to a rodent bait station.
Bait including toxins, poison, etc., may be used to attract rodents. Rodents ingest the bait and are killed by the toxins, poison, etc., in the bait. To prevent non-targeted animals, e.g., pets, etc., and unauthorized individuals, e.g., children, from coming into contact with or accidentally ingesting the bait, the bait may be located in a housing of a rodent bait station. The housing may include an opening configured to allow rodents access to the interior of the bait station to access the bait.
The bait station can be generally described as a housing that encloses an interior space which contains the bait. The housing has one or more entry points that allow the pest to enter the device and ingest the bait. Once ingested, the pest typically leaves the bait station and dies some time thereafter.
The housings typically include provisions for holding the bait in place. For example, preformed blocks of rodenticide or soft bait rodenticide, etc. may be situated on rods or the like within the interior space of the housing. This keeps the bait readily accessible to the pest. Such bait stations may come in a variety of sizes, have a variety of cosmetic designs, and allow for the use of multiple pieces of bait at once.
Some known bait stations include U.S. Pat. No. 9,629,353 and U.S. Publ. No. 2021/0015090. While these designs are highly functional, the present disclosure provides improvements over the current state of the art.
Examples of the present disclosure provide new and improved bait stations and bait racks for used in bait stations.
In an example, a bait rack including a mounting leg and a bait support portion is provided. The mounting leg has a bottom free edge and at least one mounting slot formed therein. The bait support portion includes an intermediate portion, an upward extending portion and a trough portion. The intermediate portion is connected to the mounting leg by a bent region formed between the mounting leg and the intermediate portion. The intermediate portion extends relative to the mounting leg in a non-parallel and non-perpendicular manner. The trough portion connects and is interposed between the upward extending portion and the intermediate portion. The intermediate portion, trough portion and upward extending panel portion forming a bait holding trough therebetween. A plurality of slots provide access to the bait holding trough from a location external of the bait holding trough. Typically, this is vertically below the bait rack.
In one example, each slot of the plurality of slots has a first end located within the upward extending portion and a second end located within the intermediate portion. Each slot extends between the first and second ends through the trough portion.
In one example, the mounting leg, intermediate portion, upward extending portion and trough portion are formed from a one-piece, continuous piece of sheet material. This sheet material could be plastic or metal. Typically, the sheet material will be stamped (e.g. bent) sheet metal.
In one example, the mounting slot extends from the bottom free edge towards the bent region.
In one example, the mounting leg is a generally planar portion, the intermediate portion is a generally planar portion and the upward extending portion is a generally planar portion.
In one example, the trough portion is generally curved and a first radius of curvature of the bent region is smaller than a second radius of curvature of the trough portion.
In one example, the at least one mounting slot includes a pair of parallel and laterally spaced apart mounting slots. Each mounting slot extends from the bottom free edge and intersects the bottom free edge.
In one example, the first ends of the plurality of slots are all located a same distance from an upper free edge of the upward extending portion and the second ends of the plurality of slots are all located a same second distance from the bent region.
In one example, the upward extending portion is generally parallel to the mounting leg.
In one example, the one-piece, continuous piece of sheet material is free of welds, and all portions are formed from a single piece of continuous material.
In an example, a bait station for containing bait includes a housing and a bait holding rack as outlined above. The housing has a housing lid and a housing body. The housing lid and housing body enclose an interior space and define at least one opening permitting access to the interior space. The housing body has a support wall defining at least a side of the interior space and extending upward from a floor of the housing body. A first mounting rib extends outward from the support wall, but within the interior space. The bait holding rack is positioned within a bait chamber of the interior space with the mounting rib extending into the mounting slot in the mounting leg.
In one example, the housing body includes opposed first and second side walls extending outward from the support wall. The housing body includes aligned first and second front walls. The first front wall extending from the first sidewall towards the second sidewall and the second front wall extending from the second sidewall towards the first sidewall. The first and second front walls defining an opening permitting access to the bait chamber. The bait chamber is generally defined by the support wall, the first and second side walls and the first and second front walls.
In one example, the bait chamber has a bait chamber height defined between the floor and a top of the support wall. A clearance is formed between a bottom side of the trough portion and the floor. A clearance height of the clearance between the floor and the bottom side of the trough portion is no less than one-third the bait chamber height.
In one example, the clearance heights at least one-half the bait chamber height.
In one example, the housing lid is pivotally connected to the housing body proximate the support wall. The housing lid covers the trough formed between the upward extending portion and the intermediate portion.
In one example, a bait loading post extends through one of the plurality of slots. The bait loading post has a free end axially received in a mounting cavity provided by the floor of the housing body. The free end may be friction fit within the mounting cavity to prevent removal thereof. The cavity may be formed by a nub extending upward from the floor of the housing body.
In one example, the bait holding rack rests vertically on a top of the mounting rib.
In one example, the first mounting rib has a leg portion and a foot portion extending from the leg portion. The leg portion extends between the foot portion and the support wall. The foot portion is spaced away from the support wall thereby defining a receiving cavity therebetween. A portion of the mounting leg is received in the receiving cavity and is positioned between the foot portion and the support wall.
In one example, the at least one mounting slot includes first and second laterally spaced apart mounting slots. Each mounting slot extends from the bottom free edge and intersects the bottom free edge. A second mounting rib is laterally spaced apart from the first mounting rib. The second mounting rib has a leg portion and a foot portion. The leg portion extends between the foot portion and the support wall. The foot portion is spaced away from the support wall thereby defining a second receiving cavity therebetween. The second mounting rib extends into the second mounting slot. A second portion of the mounting leg is received in the second receiving cavity.
In one example, the bait holding rack hangs from the support wall and first mounting rib.
In one example, the free edge of the mounting leg is spaced a first distance from the floor, the first distance being smaller than the clearance height.
Other aspects, objectives and advantages of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
The accompanying drawings incorporated in and forming a part of the specification illustrate several aspects of the present invention and, together with the description, serve to explain the principles of the invention. In the drawings:
While the invention will be described in connection with certain preferred embodiments, there is no intent to limit it to those embodiments. On the contrary, the intent is to cover all alternatives, modifications and equivalents as included within the spirit and scope of the invention as defined by the appended claims.
Referring to the figures generally, an embodiment of a bait station 20 is provided. Various different types of bait, e.g., bait blocks, soft bait, etc., may be placed in and used with the bait station. Soft bait may be provided in wrappers, e.g., sachets, paper sachets, etc. When rodents consume the bait, portions of the wrappers may be left behind and/or may become located outside of the bait station, which may be undesirable, e.g., be visually displeasing, potentially have portions of bait stuck to scraps of wrapper located outside the bait station, etc. Therefore, an embodiment of a bait rack 36 is provided to support the bait in the housing 22. The bait rack 36 is configured to allow bait, e.g., soft bait, to be placed directly on the rack without a wrapper. Additionally, the bait rack 36 allows rodents to access the bait located on the bait rack from below, but not to remove all of the bait from the bait rack 36 at once. Moreover, the bait rack 36 allows bait to be dropped into the bait compartment of the bait rack without the need to further manipulate the bait to secure it within the bait station, e.g., without need to secure bait, e.g., to bait rods, etc.
With reference to
The housing lid 26 is pivotably attached to the housing body 23. A user may pivot the housing lid 26 between an open configuration (
The lid 26 includes keyholes 28 through which a locking mechanism may be actuated by a key to lock the lid 26 in the closed configuration, e.g., after bait has been loaded into the bait station 20, and to unlock the lid 26 to allow it to be pivoted to an open configuration to allow loading of bait into the bait station 20.
In this example, the bait station 20 also includes a bottom anchoring portion, shown as concrete base 30, configured to anchor the housing 22 to prevent movement of the housing 22, e.g., by rodents, wind, etc. However, other examples need not include the concrete base 30.
With reference to
The bait rack 36 is mounted to a support wall 38 of the housing body 23 that defines, at least in part, the interior space 31 and particularly bait chamber 34. The support wall 38 includes a pair of mounting ribs 40 that cooperate with the bait rack 36 to mount the bait rack 36 within the bait chamber 34.
With reference to
Portions of the bait rack 36 are received in the receiving cavities 45 to secure the bait rack 36 to the support wall 38.
The mounting slots are formed in a mounting leg 48 of the bait rack 36. The mounting slots 46 extend upward from a free edge 50 of the mounting leg 48. In other embodiments, it is contemplated that mounting slots 46 could be offset from free edge 50 and not intersecting with free edge 50.
The mounting slots 46 are generally parallel to one another and laterally spaced apart.
In this example, the region 52 of the mounting leg 48 located between the mounting slots 46 is positioned laterally between the mounting ribs 40 when the bait rack 36 is mounted.
In this example and with reference to
The cooperation of the foot portions 44 and region 52 can prevent tilting or tipping of the bait rack 36 when mounted within the bait chamber 34.
Other examples could be free of the foot portions 44 or could have the foot portions extend away from one another.
The top ends 57 of the mounting ribs 40 are spaced a distance D1 away from the top edge of the support wall 38. The inward ends 54 of the slots 46 rest, in some examples, on the top ends 57 of the mounting ribs.
With reference to
In an example, mounting leg 48 is connected to the intermediate portion 60 by a bend 66. The intermediate portion extends at a non-parallel, non-perpendicular orientation relative to the mounting leg 48.
The trough portion 64 connects the upward extending portion 62 to the intermediate portion 60. The upward extending portion 62, intermediate portion 60 and trough portion 64 form a trough 65 for holding bait.
In the illustrated example, the trough portion 64 is a curved portion. However, in other examples, the trough portion 64 need not be curved.
With reference to
Further, in this example, the upward extending portion 62 is generally planar, the intermediate portion 60 is generally planar and the mounting leg 48 is generally planar. The upward extending portion 62 is generally parallel to the mounting leg 48 (e.g. plus or minus 10 degrees and preferably less than plus or minus 5 degrees from parallel).
In the illustrated example, the entirety of the bait rack 36 is formed from a single, continuous piece of sheet material. Preferably, the bait rack 36 is formed from sheet metal such as sheet aluminum or sheet steel. The sheet metal can be formed by bending to define the entirety of the cross-sectional shape (e.g. as illustrated in
In one example, and as illustrated in
With reference to
With reference to one slot 76, but applicable to all of the slots 76 in the current example, the slot 76 includes a first end 82 formed in the upward extending portion 62 and a second end 84 in the intermediate portion 60. The slot 76 extends through the trough portion 64 between the first and second ends 82, 84. Thus, slots 76 provide access to the trough 65 from below the bait rack 36.
While other slot arrangements are contemplated, in this example, the first end 82 of each slot is a same distance from free edge 70 of the upward extending portion 62. Additionally, the second end 84 of each slot is a same distance from bend 66.
With reference to
The bait rack 36 is generally located between these walls 38, 86, 88, 90, and 92 when mounted within the housing 22.
Preferably, the bait rack 36 and particularly the trough portion 64 thereof is located vertically above and spaced from floor 94 forming a clearance 96 between the floor 94 and the bottom side of the trough portion 64.
In one example, the height between the floor 94 and the top of the support wall 38 defines a bait chamber height H4 of the bait chamber 34. In an example, a clearance height H3 between the floor 94 and the bottom side of the trough portion 64 is no less than one-third the bait chamber height and preferably at forty percent the bait chamber height. In one example the height H3 is at least 1.25 inches and in a particular embodiment it is approximately 1.5 inches. In one example, the bait chamber height H4 is between about 2.875 and 3.375 inches and in a particular examples is about 3.125 inches.
In one example, the spacing from the floor 94 to free edge 50 of the mounting leg 48 is less than the clearance height.
