Description

[0001] Rodent trap with tiltable channel and optional storage or discharge mechanism

[0002] Technical field of the invention

[0003] The present invention relates to the field of rodent traps.

[0004] Background of the invention

[0005] Rodent traps currently available on the market typically employ sensitive trigger mechanisms, such as pressure plates or infrared sensors, that detect the presence of a rodent. Upon detection, a rapid and humane killing method, such as a high-voltage electric shock or a spring-loaded bar, is activated to humanely kill the rodent.

[0006] A significant issue associated with these traps is the odour generated by killed rodents, particularly when multiple rodents are collected over time. To address this, certain traps incorporate a dedicated storage compartment where the carcasses are deposited post-kill. These compartments are generally constructed from durable, non-corrosive materials such as stainless steel or high-grade plastics to ensure hygiene and ease of cleaning.

[0007] In some designs, small conveyors or other automated transfer mechanisms are employed to move the killed rodent from the killing zone into the storage compartment. While this approach helps maintain separation between live rodents and carcasses, it introduces several challenges, including mechanical reliability, increased power consumption, spatial constraints, and overall system complexity. An alternative solution found in some systems involves automatically ejecting or transferring the rodent carcass to a location outside the trap, where it may be consumed by scavenging wildlife. While this method can reduce storage needs and, in some cases, may assist with odour control, it introduces additional uncertainties. The mechanical system required for external disposal may still be complex and prone to failure, and if wild animals do not locate and consume the carcass promptly, odour and hygiene issues may persist or worsen.

[0008] Accordingly, there remains a need for a rodent trap system that offers effective, hygienic disposal of carcasses while addressing the challenges of odour management, mechanical simplicity, and operational reliability.

[0009] Object of the Invention

[0010] The objective of the present invention is to provide a compact rodent trap with odour tight storage and with little need for maintenance apart from scheduled service visits.

[0011] Summary of the Invention

[0012] The present invention relates to a rodent trap comprising a movable channel part for guiding and disposing of rodents, optionally in combination with a storage container. The invention addresses key challenges in rodent trapping, such as hygienic disposal, odor control, escape prevention, and mechanical simplicity.

[0013] According to one aspect of the invention, a rodent trap comprises a housing with a first entry opening, a first channel part having a first end with an opening, a top wall, a bottom wall, a side wall, and an opposing side opening. The trap further comprises a transport mechanism adapted to move the first channel part between a lower position, in which the first end’s opening is aligned with the entry opening, and an upper position, in which the channel part is tilted toward an outlet facing the surroundings or toward an inlet of a storage container. In the lower position, the side opening faces a wall section or other barrier element to prevent escape.

[0014] In some embodiments, the side opening is provided with a first side wall hingedly connected to the top or bottom wall of the channel part. In other embodiments, the side opening is left uncovered and serves as a direct discharge path during tilting.

[0015] In one embodiment, a killing mechanism is placed within the first channel part. The killing mechanism may be configured for electrocution and comprises at least two electrically isolated electrodes, wherein a high-voltage potential difference is applied upon detection of a rodent.

[0016] The invention also provides for the channel part to be lifted to a position where its first end’s opening is removed from the entry opening, thereby preventing escape. In this position, the killing mechanism may be activated.

[0017] In some embodiments, the movement of the channel part is aided by one or more guide elements, including guide pins, guide recesses, and / or guide channels. The guide elements may be arranged on the housing, a wall section, or the storage container. In certain configurations, a guide pin on the channel part follows a curved guide channel during movement, thereby controlling the tilting motion. In other configurations, the guide pin engages a guide recess to stabilize the channel in a target position.

[0018] When the channel part tilts toward a storage container, the container may be equipped with a sealed lid comprising lips or handles. The channel part or transport mechanism may be adapted to lift the lid during movement to allow rodent transfer through the side opening. The container may be removable, fitted with disposable bags, and include an indicator system to alert when full. In alternative embodiments, the trap does not include a storage container. Instead, the side opening tilts toward a wall section configured as a chute that directs the rodent toward an external outlet. The outlet may be covered by a hinged plate that opens upon engagement by the killed rodent.

[0019] In general, the wall section may be formed integrally with the housing or as a separate panel. It may be planar, curved, or contoured to match the geometry of the channel part. In chute-based embodiments, the upper part of the wall section may form or support a chute structure to guide discharge of the rodent.

[0020] The invention thereby provides a highly adaptable and hygienic rodent trap system with options for both contained and open disposal, various mechanical configurations, and enhanced automation potential.

[0093] Detailed Description of the Invention

[0094] In the present context, the term “in general” when used when mentioning a feature relating to the present invention, it must be understood that the feature may be used with all embodiments of the invention, even if the mentioning is made in the detailed part of the document. In one or more embodiments, the housing further comprises a second entry opening, wherein the rodent trap further comprises a second channel part with the same characteristics as the first channel part, including an opening in a first end, a bottom wall, a side opening, and a top wall.

[0095] In some embodiments, the transport mechanism, or a separate transport mechanism, is adapted for transporting the second channel part within the housing between a lower position where the first end’s opening is arranged in extension of the second entry opening, and an upper position operably connected to the storage container’s inlet.

[0096] In one or more embodiments, the second channel part comprises a first side wall facing a wall section or a storage container when the second channel part is in its lower position, said first side wall being hingedly connected to the second channel part’s top wall or bottom wall. In some embodiments, the entire second channel part is adapted for being tilted towards the storage container or an outlet when the second channel part is in its upper position.

[0097] Preferably, the first and second channel parts are arranged in line to one another.

[0098] In one or more embodiments, the first and second channel parts each comprises an opening in a second end, opposite to the respective first end, thereby allowing light to pass from the first entry opening to the second entry opening, and vice versa. In one or more embodiments, the second end of each first and the second channel part is adapted for preventing target animals, preferably rodents, from passing there through. This could e.g., be by closing the second end with a window or making it’s opening so narrow that the target animal cannot pass there through. Alternatively, the second end could be blocked by parts of a trigger mechanism integrated in or being part of the killing mechanism. These embodiments secure that the target animal is correctly positioned when the killing mechanism is activated to secure a humane killing of the target animal. In one or more embodiments, a light transparent wall is positioned between said first and second channel parts, thereby preventing a rodent from passing from the first channel part and into the second channel part, and vice versa.

[0099] In one or more embodiments, the light transparent wall is perforated, thereby allowing air to travel from the first entry opening to the second entry opening, and vice versa.

[0100] In one or more embodiments, the rodent trap further comprises a bait zone positioned between the first and the second channel parts.

[0101] In one or more embodiments, the rodent trap further comprises:

[0102] - a first killing mechanism placed in the first channel part; and

[0103] - a second killing mechanism placed in the second channel part.

[0104] By integrating two killing mechanisms, it increases the capacity (including the possibility of a rodent entering from both sides) of the trap, but at the same time this makes the trap more complicated. To counteract this problem, the first killing mechanism is placed in the first channel part, and the second killing mechanism is placed in the second channel part. A bait zone may be positioned between the first and the second channel parts such that it is shared by the two killing mechanisms. Alternatively, the bait zone may be integrated into the wall of the storage container, e.g., the wall facing the channel part(s).

[0105] In one or more embodiments, the second ends of the first and the second channel parts together define a receptacle, or a part of a receptacle, adapted for receiving bait.

[0106] In one or more embodiments, the second ends of the first and the second channel parts together define a receiving section adapted for receiving a receptacle adapted for receiving bait.

[0107] In one or more embodiments, the first and second killing mechanisms each are adapted for electrocution of a rodent, wherein the first and second killing mechanisms each comprises a first electrode and a second electrode; wherein the first electrode is electrically isolated from the second electrode, and wherein the electrocution occurs when a high-voltage potential difference between the first and second electrodes is generated.

[0108] In one or more embodiments, the number of electrodes is at least three, wherein the electrodes are arranged sequentially in the channel part, the first electrode of the at least three electrodes being connected to a third electrode of the at least three electrodes, while the second electrode of the at least three electrodes is electrically isolated from the first and third electrodes, and wherein the electrocution occurs when a high-voltage potential difference between the first or third and second electrodes is generated.

[0109] In one or more embodiments, the power source for generating the high-voltage potential difference is a low voltage, high-capacity DC-battery.

[0110] In one or more embodiments, the second end of each first and the second channel part is adapted for preventing target animals, preferably rodents, from passing there through, and wherein the first end of each first and second channel part is facing the respective first and second entry opening.

[0111] In one or more embodiments, each first and second killing mechanism comprises a triggering mechanism positioned in the respective second end of the first and the second channel part.

[0112] In one or more embodiments, at least the bait zone is concealed within a housing. In one or more embodiments, the housing comprises air channels adapted to allow fresh air to enter the bait zone and to pass the scent of the bait to the outside of the housing.

[0113] Figure 1 illustrates an embodiment of a rodent trap 100 according to the invention. The rodent trap 100 is here embodied as a dual catch trap. Dual catch traps, also known as double-ended traps or double entry traps, are a type of trapping device normally used to capture and contain animals, although many newer traps include killing mechanisms, such as snap traps. As the name suggests, these traps have two entry points 112 (only one can be seen), increasing the likelihood of catching an animal by providing multiple access points. The design of dual catch traps is based on the principle that animals are more likely to enter a trap if they can see through it or if they perceive an escape route on the other side. The trap has two entry points 112 located opposite each other, generally at the ends of the housing 110. The housing 110 may in some embodiments comprise air channels (not shown) adapted to allow fresh air to enter a bait zone and to pass the scent of the bait to the outside of the housing 110.

[0114] In general, the rodent trap 100 comprises a housing 110 that encloses most of the electrical and mechanical parts. The housing 110 is designed to protect the different mechanisms from tampering and environmental factors. Figure 2 shows the dual catch trap 100 without a housing, an embodiment that is also contemplated within the scope of the present invention. Here, the bait zone may need to be shielded to avoid direct access thereto by a target animal. Such a shield could be a simple plate, e.g., a perforated plate.

[0115] In general, the storage container 120 plays a crucial role in ensuring hygienic disposal and effective odour control. The storage container 120 may be designed using durable and non-corrosive materials, such as stainless steel and highgrade plastics, which provide long-term usability and ease of cleaning.

[0116] In general, the storage container may comprise a lid (preferably of metal, such as steel, or plastic reinforced by metal, such as steel) that securely seals the compartment to prevent any odours from escaping and to protect the interior from external elements.

[0117] In general, the trap may comprise a storage container 120, a first channel part 130, and a transport mechanism 180 adapted for transporting the first channel part 130 between a lower position and an upper position.

[0118] In general, the transport mechanism may be implemented as a wire rope unit, motorized linkage, scissor lift, or another mechanical actuator capable of lifting and tilting the channel part.

[0119] The first channel part 130 (and if present, also the second channel part 140) is generally adapted for holding a rodent. The channel part 130, 140 of a rodent trap serves as the essential entry pathway designed to lure rodents into the trap. This component guides the rodent from the entrance point(s) 1 12, 114 (see Figure 3) to the capture or killing mechanism, ensuring it follows a specific path that leads to its containment. Typically constructed from durable materials, like high-grade plastics or metals, such as stainless steel or aluminium, the channel 130, 140 is built to withstand gnawing and repeated use.

[0120] The design of the channel 130, 140 often incorporates a smooth interior surface to prevent the rodent from finding purchase and turning around, thus guiding it efficiently towards the trap mechanism.

[0121] Bait placement within the channel 130, 140 is strategic, usually located at the far end near a trigger mechanism. This positioning ensures the rodent must fully enter the channel to reach the bait, thereby triggering the trap effectively. The seamless integration of the channel with the trap’s trigger mechanism is crucial for activating the capture or killing process at the right moment when the rodent is fully inside. The type of bait used depends on the species being targeted and can include food, pheromones, or other enticing substances.

[0122] The design of the channel may also prioritize hygiene and ease of maintenance. Smooth surfaces and removable parts facilitate easy cleaning, ensuring the trap remains sanitary and effective over time. Some designs may include disposable liners or accessible panels to further aid in maintenance, making the trap more user-friendly.

[0123] Overall, the channel part 130, 140 is integral to the trap’s functionality, effectively luring, guiding, and capturing rodents while ensuring easy maintenance and high efficiency in rodent control.

[0124] The storage container’s lid 122 may in general be designed with integrated lips 124 or handles that allow for easy grasping by the transport mechanism 180. These lips 124 are strategically placed to enable automated systems to lift and remove the lid 122 efficiently. The weight of the lid 122 ensures that it stays securely in place, preventing any accidental openings or escape of odours.

[0125] In general, when the transport mechanism 180 is activated, it engages with the lips 124 on the lid 122, lifting it smoothly and allowing access to the interior of the storage container 120. Once the rodent is deposited into the container 120, the mechanism places the lid 122 back into position, preferably ensuring a tight seal.

[0126] By combining a heavy, well-sealed lid with easy-to-grasp lips for automated handling, this storage container design effectively addresses the challenges of odour control and secure containment in rodent traps. For maintenance and ease of use, the storage container may in some embodiments be releasably fastened to the housing, thereby being easily removable to facilitate cleaning and transport of rodents. This design allows users to handle the container without direct contact with the rodents. An indicator system, such as a visual cue or digital display, may be present to inform users when the container is full and needs to be emptied. Alternatively, or in combination, the rodent trap may comprise a transmitter unit configured for sending such information.

[0127] Hygienic disposal is also a key consideration. The storage container may in some embodiments be designed to accommodate disposable, e.g., biodegradable, bags that can be sealed and discarded, minimizing exposure to pathogens. Optional features like handles and secure locking mechanisms ensure that the storage container can be handled safely during disposal.

[0128] Returning to the first 130 and second 140 channel parts, they are generally provided with a top wall 134, 144, a bottom wall 132, 142, and two (a first and a second side wall) opposing side walls 136, 146, 138, 148 (see Figures 2 and 4). The channel parts 130, 140 may together be configured as a single channel or may individually comprise one or more individual channel sections. In the disclosed embodiment, they are configured as individual channel parts fastened to one another and divided by a common petition wall 150 (see Figure 8). In general, they may be lifted by the same or different transport mechanisms. The petition wall 150 is here both perforated and light transparent, thereby allowing air and light to travel from the first entry opening 112 to the second entry opening 114, and vice versa.

[0129] In general, when the channel part 130, 140 is in its lower position, the first side wall 136, 146, faces the storage container 120. The first side wall 136, 146 is here hingedly connected to the channel part’s top wall 134, 144 but could alternatively be hingedly connected to the channel part’s bottom wall 132, 144. In general, the entire channel part 130, 140 is adapted for being tilted towards the storage container 120 when in its upper position. Thereby, the rodent tilts towards the first side wall 136, 146 that opens into the storage container 120. In the specifically disclosed embodiment, the transport mechanism 180 uses the channel part 130, 140 to lift and open the storage container’s lid 122 by engaging the top wall 134, 144 of the channel part 130, 140 with the lips 124, thereby allowing the first side wall 136, 146 to open into the storage container 120. In this way, the channel part 130, 140 is operably connected to the storage container’s inlet. In general, the lifting and tilting movement of the channel part 130, 140 may be controlled by guide means. Such guide means may be configured in many ways. In the specifically disclosed embodiment (see Figures 4 and 5), such guide means 190 are mounted both on the storage container 120 and on the inside of the housing 110. The channel part 130, 140 is also provided with a guide pin 192 that is adapted for engaging with a guide recess 194 formed in or mounted to the storage container 120. Apart from the guide means 190, 192, 194, the transport mechanism 180 is here (see Figures 6 and 7) shown comprising a wire pull unit 182. The wire pull unit 182 is designed to lift the channel 130, 140 and subsequently the lid 122 and involves a coordinated system where the channel itself initiates the lifting of the lid. The channel 130, 140, which serves as the entry pathway for the rodent, is connected to a wire rope system. This system is controlled by an electric actuator or motor unit 184 that provides the necessary force to lift the channel 130, 140.

[0130] When the actuator / motor unit 184 is activated, the wire rope (not shown) pulls the channel 130, 140 upward, e.g., by being attached with one end to the top wall 134, 144 of the channel 130, 140. As the channel rises, it engages with the heavy lid 122 positioned on top of the storage container 120. The lid 122, designed with specific lips 124 or handles, is grasped and lifted by the channel’s movement. This integrated lifting mechanism ensures that both the channel and the lid are raised simultaneously. As the channel 130, 140 lifts, a door on its side wall, or the entire side wall 136, 146 configured as a door, opens. This door allows the rodent to exit the channel 130, 140 and be deposited into the storage container 120 below. The actuator then reverses its motion, lowering the channel 130, 140 and the lid 122 back into place. The lid 122 securely seals the storage container 120, effectively containing any odours and maintaining hygiene.

[0131] The system generally operates automatically, with a control system (not shown) coordinating the lifting and lowering processes based on specific triggers, such as the detection of a rodent or the need to deposit the rodent into the container 120. This design minimizes the need for manual intervention, ensuring a seamless and efficient operation. The use of a durable wire rope and strategically placed pulleys 186 ensures the long-term reliability of the mechanism, while the heavy lid 122 provides effective odour containment.

[0132] The shown pulley setup (see Figure 7) involves a precise arrangement for smooth and efficient operation. The system begins with a motor unit 184 equipped with a driving pulley, known as the first pulley. This motor unit 184 provides the necessary pulling force.

[0133] Mounted on a common axle are three pulleys. The centre pulley on this axle is connected to the first pulley via a separate wire rope (not shown), allowing the motor’s force to be transferred to the centre pulley. The two outer pulleys on the common axle are each connected to the channel 130, 140 using separate wire ropes (not shown), extending from the pulleys to fixed points on the channel to ensure even and smooth lifting. When the motor unit 184 activates, it turns the first pulley, which pulls the wire connected to the centre pulley on the common axle. As the centre pulley rotates, it distributes the pulling force to the two outer pulleys, ensuring both sides of the channel 130, 140 are lifted simultaneously. This synchronized movement lifts the channel 130, which then engages with the lid 122 positioned above the storage container 120 (see Figure 9). In the shown embodiment, a first killing mechanism 160 is placed in the first channel part 120, and a second killing mechanism 170 is placed in the second channel part 140 (see Figure 8). The killing mechanisms 160, 170 are here shown embodied as adapted for electrocution of a rodent. The killing mechanisms 160, 170 each comprises three electrodes and arranged sequentially in the channel part 130, 140. The first electrode 162 is connected to the third electrode 166, while the second electrode 164 is electrically isolated from the first 162 and third 166 electrodes. The electrocution occurs when a high-voltage potential difference between the first 162 or third 166 and second 164 electrodes is generated, i.e., when the rodent touches the plates simultaneously.

[0134] In general, the storage container 120 may be especially designed for bag insertion that ensures secure, hygienic, and convenient waste disposal. Figures 10-12 show an embodiment of the storage container comprising three main components: a container 121 , a frame 123, and the lid 122. The bag is not shown but may be disposable, preferably a plastic bag to avoid leakage.

[0135] In general, the container 121 forms the main body of the storage container 120 and can come in various shapes, such as cylindrical, rectangular, or another practical configuration. It is typically constructed from durable materials, such as high-density polyethylene (HDPE) plastic, or stainless steel, providing the necessary strength to support the weight and volume of the intended waste. The container’s surface may be smooth or textured, and it might feature additional functional elements, such as handles or wheels for easy mobility.

[0136] The frame 123 is a critical component designed to mount securely onto the top edge or top rim of the container 121 . It serves the dual purpose of providing a stable structure to hold the bag in place and forming an airtight seal. The frame 123 is generally made from the same material as the container to ensure compatibility and durability. Its design may include a specifically engineered groove or lip, into which the top edge of the plastic bag is inserted. This groove ensures that when the frame 123 is pressed down onto the container, the plastic bag is clamped tightly between the frame and the container’s rim. This clamping action not only secures the bag but also creates an airtight connection, preventing any odours from escaping.

[0137] Integral to the frame 123 is the lid 122, which is hingedly connected to the frame 123, allowing it to be easily opened and closed. The hinges are preferably robust, typically made from metal or reinforced plastic, to withstand repeated use. The lid 122 itself is preferably designed to match the frame’s dimensions perfectly, e.g., ensuring a snug fit that maintains the airtight seal when closed. The top of the lid might feature a handle or lip 124, as previously described for hands-free operation, adding to the convenience and hygiene of the system. The lid’s material, similar to that of the container and frame, is chosen for its durability and resistance to wear and tear.

[0138] The frame 123 may, as shown in Figure 12, be designed with a ring groove 126. This ring groove 126 is specifically adapted to receive and securely fit around the top rim of the container. The groove 126 is engineered to match the dimensions and shape of the container’s top rim precisely, ensuring a snug and stable fit. When the frame 123 is placed onto the container 121 , the top rim of the container slides into the ring groove 126, effectively anchoring the frame 123 to the container 121 . This design not only secures the frame 123 but also ensures that the bag clamped between the frame and the container’s top rim forms an airtight seal, preventing any odour escape. The secure placement of the bag also prevents it from slipping into the container 121 , which can be messy and inconvenient.

[0139] In one or more embodiments, the storage container further comprises a lid attached to the frame via one or more hinges. In one or more embodiments, the frame comprises a top rim configured as a sealing ring.

[0140] In one or more embodiments, the frame comprises a ring groove adapted to receive and fit around the top rim of the container.

[0141] In one or more embodiments, the lid is designed with integrated lips or handles that allow for easy grasping by the transport mechanism.

[0142] Figure 13 illustrates an embodiment of the rodent trap 100 wherein the first channel part 130 is not provided with a hinged side wall. Instead, the first channel part 130 includes a side opening that is open when the channel part 130 is tilted. In this embodiment, the side opening is positioned to face the inlet of a storage container 120 when the channel part 130 is in its upper position. The rodent (not shown) is guided by gravity through the open side opening and into the container 120. The design simplifies construction and eliminates moving wall parts while still ensuring reliable transfer of the killed rodent. In the lower position, shown in the figure, the side opening faces a wall section of the container, thereby preventing the rodent from escaping prior to activation. The channel part 130 is lifted and tilted using a transport mechanism 180, optionally guided by one or more guide elements, such as guide pins 192 and guide recesses 194.

[0143] The previously described embodiments illustrate rodent traps configured to discharge killed rodents into a sealed storage container, offering secure containment and odour control. However, the invention is not limited to container-based disposal systems. In alternative embodiments, the rodent is discharged directly to the surroundings, for instance by means of a chute and outlet mechanism. These embodiments eliminate the need for a storage container while still providing reliable and hygienic disposal. Figures 14 and 15 illustrate such container-free implementations of the invention. Figure 14 shows an embodiment of the trap 100 that does not include a storage container. Instead, the rodent is disposed of via a chute 220 integrated into or mounted adjacent to a wall section 210. In the illustrated lower position, the first channel part 130 is aligned with the first entry opening (not shown), allowing a rodent to enter the trap. The side opening of the channel part 130 faces a wall section 210, thereby preventing premature escape. A hinged plate 230 is located at the bottom of the chute 220, covering an outlet to the surroundings. The plate 230 remains closed while the trap is in its idle state to contain odour and prevent pests from entering the outlet.

[0144] In general, the hinged plate may be spring-biased or gravity-biased to return to a closed position. In some embodiments, the plate is sufficiently light or pivotally balanced to be opened by the weight of a falling rodent alone.

[0145] Figure 15 illustrates the same embodiment as Figure 14, but with the first channel part 130 in its upper and tilted position. In this configuration, the side opening of the channel part 130 is aligned with the chute 220 formed by the wall section 210. As the channel part 130 tilts, the killed rodent (not shown) is discharged through the side opening and into the chute 220. Upon impact, the rodent engages and pushes open the hinged plate 230 covering the outlet. This allows the rodent to fall to the ground or into a secondary containment space, after which the hinged plate 230 returns to a closed position, either via gravity or a spring mechanism. This embodiment eliminates the need for a storage container while maintaining functional odour control and passive rodent disposal.

[0146] In some embodiments, the killing mechanism is activated only when the first end of the channel part is removed from the entry opening, to ensure containment prior to activation. In some embodiments, the rodent trap comprises a sensor unit for detecting the presence of a rodent in the channel part. The sensor unit may be connected to a control unit, which is configured to initiate the lifting of the channel part and subsequent activation of the killing mechanism. In some embodiments, a short delay is implemented after lifting to ensure the rodent is fully inside before activation.

[0147] The control unit may include logic to delay killing after lifting, detect sensor input thresholds, or coordinate with an external alert system. In some embodiments, the control unit is implemented as a microcontroller with preconfigured operation sequences.

[0148] In some embodiments, the container is provided with an integrated level sensor or weight sensor, operatively connected to a visual indicator or remote alert system, to inform a user when the container is full.
