I. Field of the Invention
The present invention relates to traps for capturing small animals such as rats, mice and other rodents. The invention provides a mechanism for trapping the animals alive and without injury, and for transporting animals once they have been trapped. In certain embodiments, the invention hides the trapped animals from view yet provides an indication of whether an animal has been trapped.
II. Related Art
Numerous traps have been provided over the years. A number of these, including those shown in U.S. Pat. No. 4,103,448 to Anthony J. Souza and U.S. Pat. No. 4,393,616 to Gilbert T. Kaufman et al are designed to humanely trap the animals. The Souza trap is a repeating trap. In other words, a plurality of animals can be trapped without resetting the trap. However, the Souza trap does not include an indicator signaling whether the trap has captured an animal. While Kaufman et al includes an indicator signaling the presence of an animal in the trap, it is not a repeating trap. Once a first animal has been captured, no second animal can be captured until the first animal is removed and the Kaufman trap is reset.
The present invention provides a repeating trap which is easy to operate and maintain. The trap obstructs viewing of animals within the trap. This is advantageous since many people are repulsed by the sight of rats, mice and other rodents. The trap includes more than one ingress opening for the animals and an indicator associated with each ingress opening. These indicators signal whether an animal is in the trap. These indicators likewise signal which ingress opening was used by an animal to enter the trap thus providing information about the direction from which the animal traveled to reach the trap. To assist in determining the number of animals within the trap, a window can be provided in the back or bottom of the trap. This window can be placed against the wall or floor of a building or other surface to block the window from view when the window is not being used to inspect the contents of the trap. Alternatively, an opaque removable covering can be provided over the window.
The animal trap of the present invention comprises an elongate base having an open top chamber defined by a front wall, a rear wall, a bottom wall, a first end wall and a second end wall. Each of the walls referenced above is substantially opaque. The first end wall and second end wall each have an animal ingress opening. The front wall has two channels, more specifically a channel associated with each ingress opening.
A first capture assembly is associated with the animal ingress opening of the first end wall and a second capture assembly associated with the animal ingress opening of the second end wall. Each of these animal capture assemblies includes a door and a ramp. The ramp is pivotal between a first position and a second position. When the ramp is in the first position, an animal can enter the ramp through the animal ingress opening. When the ramp is in the second position, the animal can exit the ramp into a storage section of the chamber. While the ramp is biased toward the first position of the ramp, the weight of an animal moving across the ramp will cause the ramp to move from its first position to its second position. To prevent the animal from escaping, a door is provided. The door pivots by movement of the ramp between a first position in which the door overlies a portion of the ramp permitting an animal to enter the ramp through the animal ingress opening, and a second position preventing an animal on the ramp from existing through the animal ingress opening. When the animal exits the end of the ramp opposite the ingress opening, the ramp and door return to their respective first positions such that the ramp blocks the path from the storage section to the ingress opening.
A first indicator is associated with the ingress opening of the first end wall. This indicator includes a channel in the front wall adjacent the first ingress opening. The channel has an opening defined by two lips and facing the interior of the chamber, a stop, and an open top. Positioned within the first channel is a shaft movable between a retracted and extended position. A neck is coupled at one end to and extends from the shaft between the two lips of the channel. An engagement member is coupled to the other end of the neck which cooperates with the lips and the stop to retain a portion of the shaft within the channel. The engagement member cooperates with the ramp of one of the capture assemblies so that, if the shaft is in its retracted position, as the ramp moves between the ramp's first position and the ramp's second position, the shaft moves from its retracted position to its extended position. A second indicator of the same construction is provided in association with the second ingress opening.
A cover closes the chamber while leaving the tops of the channels of the indicators uncovered. As such, the shafts of the first and second indicators are permitted to move between their retracted and extended positions. In some embodiments, the cover cooperates with catches on the shafts of the first and second indicators to retain the shaft of an indicator in its extended position when the ramp that moved the shaft returns to the ramp's first position. In these embodiments, the position of the shaft serves to indicate the presence of an animal in the trap. In another embodiment, the cover cooperates with a catch on a flag pole to hold the flag in an undeployed position. Upward movement of the shaft caused by movement of the ramp releases the catch so that the flag pole and flag attached to the flag pole move into a deployed position. In these embodiments, the position of the flag provides an indication of the presence of an animal in the trap.
In still other embodiments, the first and second capture assemblies each include a second one-way door. The second one-way door is positioned between the ramp of the capture assembly and the storage section of the trap. As an animal exits the ramp, the animal pushes the second one-way door into an open position permitting the animal to proceed into the storage section. The second one-way door then swings closed behind the animal preventing the animal from exiting the storage area. Specifically, the second one-way door swings back into its closed position until it engages a stop. The stop prevents an animal inside the storage area from pushing on the door to open it. The surface of the second one-way door facing the storage section when the door is in the closed position is relatively smooth and the distances between the edges of the second one-way door and the walls of the trap's base are sufficiently small such that an animal inside the storage space is prevented from pulling the second one-way door open.
The concepts of the present disclosure may be employed in various alternative forms. The following description of specific exemplary embodiments shown by way of the drawings is provided to meet the disclosure requirements of the patent laws. However, the reader should understand that the present invention is not limited to the embodiment shown in the drawings or described herein.
A first animal trap 1 made in accordance with the present invention is shown
As shown in
The traps shown in the drawings can be referred to as live or humane traps. This is because the trap 1 does not destroy the animals, but rather captures the animals so they can be transported to a more suitable location while still in the chamber of trap 1 and then set free by opening the cover 24. The trap 1 can also be described as a repeating trap since its capture assembly 30 resets itself after an animal has been captured to permit capture of additional animals. The capture assembly 30 that provides repetitive humane trapping of the animals will now be described.
As shown, end wall 20 has an animal ingress opening 21 and end wall 22 has an animal ingress opening 23. A separate capture assembly 30 is associated with each of the ingress openings 21 and 23. Between the two capture assemblies 30 is the storage section 13 of the chamber 12. Bait can be placed in the storage section 13 which also houses animals after capture. Each capture assembly 30 includes a door 32 and ramp 34. The door 32 includes a plate 36 and an axle 38. The width of the plate 36 is slightly less than the distance between the front wall 14 and the rear wall 16. The axle 38, located near the bottom of the plate 36, rotationally secures the door 32 to the front wall 14 and the rear wall 16 so the door 32 can pivot between a first position (see
When the ramp 34 and door 32 are in their respective first positions as shown in
As shown in
The trap 1 shown in the drawings offers a number of advantages. First, animals can enter the trap from either end. Second, the capture assembly 30 at each end resets itself each time an animal exits one of the ramps 34 into the storage section 13 of the chamber 12. Thus, the trap 1 can capture additional animals without being reset by a person. Third, the design of the trap 1 permits a variety of baits to be used. These are easily positioned within the storage section 13 of the chamber 12 when the cover is removed. Fourth, the trap 1 hides the animals from view, such as rats and mice, that may be trapped within the storage section 13 of chamber 12. Many people consider such animals to be dirty, germ-carrying and repulsive. This has been true since the Middle Ages when people first associated such animals with the black plague. The trap 1 shown in the drawings has an additional feature which will now be described.
While it is often important to conceal the contents of the storage chamber 13 from view, it is also beneficial to provide a clear indication of the presence of one or more animals within the trap 1. This can be achieved by forming at least a portion of the base 10 or cover 24 of a non-opaque material. Such a material may be translucent or transparent. It is also beneficial to know the direction from which an animal came before entering the trap. Thus, the trap 1 shown includes a separate indicator 50 associated with each of the ingress openings 21 and 23. The indicators 50 will tell the user whether there is at least one animal in the trap that entered through a particular ingress opening 21 or 23 and thus whether animals entering the trap 1 likely approached from one side of the trap 1, the other side of the trap 1, or both sides of the trap 1. When such indicators are employed, the base 10 and cover 24 may be made of opaque materials.
As shown in the drawings, proximate each end wall 20 and 22 along front wall 14 is a channel 52. The channel 52 has an open top 54, a pair of opposing lips 56 and 58 defining a space open to the chamber 12, and a stop 62. Positioned within each channel 52 is a shaft 64 movable between a retracted position and an extended position in which the top of the shaft 64 is raised over the open top 54 of the channel 52. The indicator 50 also includes a neck 66 projecting from the shaft 64 between the lips 56 and 58 of the channel 52. Secured to the end of the neck 66 opposite the shaft 64 and outside the channel 52 is an engagement member 68. The engagement member 68 performs two functions. First, the bottom of the engagement member engages a portion of the ramp 34. As the ramp 34 moves between its first position and its second position, the shaft 64 moves from its retracted position to its extended position. In the embodiment shown in
As shown in the drawings, the cover 24 has a recess 70 aligned with the top of each channel 52 to permit the shaft 64 to slide within the channel 52 between its retracted and extended position as the ramp 34 moves from its first position to its second position. In the embodiment shown in
The complexity and redundancy of the arrangement shown in
Those skilled in the art will appreciate from the foregoing that various changes may be made to the embodiment of
As shown in
The trap of the embodiment shown in
In fact, given the arrangement of ramp 34 and the doors 36 and 102, there is no position of ramp 34 in which both doors are open. If door 36 is open, door 102 is closed as shown in
As should be clear from the foregoing, the present invention provides an improved humane repeating trap. By providing a window 17 one can view the contents of the trap 1 without opening the cover 24. Opening the cover 24 could permit a trapped animal to escape. By covering the window 17 such as by placing the window against a wall as shown in
Thus, the present trap provides advantages over prior traps that are not repeating traps. The present invention provides advantages over prior traps which do not shield the contents from view. The present invention provides advantages over prior traps which do shield the contents from view, but do not permit viewing of the contents without opening the trap. The present invention also provides advantages over prior art traps which shield the contents from view, but fail to provide any indication of the presence of an animal within the trap. The present invention also provides advantages over any multiple point of entry trap that provides an indication of the presence of an animal within the trap, but does not indicate the point(s) of entry used by animals to enter the trap.
The foregoing description is provided to meet the disclosure requirements of the patent laws, but is not intended to be limiting. The invention is defined and limited only by the following claims.
