BACKGROUND OF THE INVENTION
This invention relates generally to the field of animal traps and more specifically to a rodent trap.
Rodents have long been a problem when they enter spaces where they are not wanted, such as peoples homes, places of business public areas and agricultural areas especially where the use of poisons is problematic.
Over the years many rodent traps have been designed, manufactured and marketed to help catch rats and mice. Some traps attempt to be humane and capture rodents live and unharmed. Other traps are meant to kill the animal.
One rodent trap invented by Paul Benzie, in his patent number 4876821, has designed a trap that includes a magnetically latched trap door so that when the rodent walks down a plank, the weight of the animal causes the magnet to detach and the plank to swing down thereby dropping the rodent into a receptacle below.
Although the Benzie design is efficient in catching rodents, it has certain deficiencies that the present invention attempts to remedy. First, although the Benzie invention claims to be able to reset itself, it appears to be a less than ideal solution because the trap door is pivoted at its far end. Second, the Benzie design relies solely on the weight of the animal to release the trap door. Since the magnet is not moveable, only certain weight animals will cause the door to trigger at the desired time. A light weight rodent may not even trigger the trap door. Other patents that disclose the use of a magnet to help facilitate the capture of rodents are Frank R Stimac's patent number 478766, Daniel B. Meyers patent number 3936972 and Melvin M. Melton's patent number 4578892. All the above patents also fail to provide an ideal rodent catching device that can catch multiple rodents without the need for human resetting, and that can be adjusted to catch rodents of different weights.
BRIEF SUMMARY OF THE INVENTION
The primary object of the invention is to provide a rodent trap that uses the rodents own muscle power and weight to activate the trap.
Another object of the invention is to provide a rodent trap that can be humane to the rodent.
Another object of the invention is to provide a rodent trap that is benign to the surrounding environment.
Another object of the invention is to provide a rodent trap that can automatically or be, or be adjusted to work for rodents of different sizes and weights
Another object of the invention is to provide a rodent trap that can reset itself without human intervention thereby allowing for the catching of multiple rodents before emptying the trap.
Other objects and advantages of the present invention will become apparent from the following descriptions, taken in connection with the accompanying drawings, wherein, by way of illustration and example, an embodiment of the present invention is disclosed.
In accordance with a preferred embodiment of the invention, there is disclosed Rodent Trap comprising: a lid, a pivot plank, a rectangular open topped box having at least a portion constructed of ferrous metal, a magnet, a pivot point, a bait holding platform, a guide panel, a climbing ramp, a rodent catching receptacle, said guide panel and said food tray fixed from side to side across one end of said rectangular box, said rectangular box having approximately half the said food tray end of the floor removed, said pivot point holding said pivot plank located approximately at half the length of said plank so that said plank can rotate about said pivot, said said pivot plank capable of removably receiving at least one magnet on its underside, said magnet capable of magnetically interacting with the floor portion of said rectangular box, so that a rodent can climb up said ramp, travel along said pivot plank, wedge itself between said pivot plank and said guide panel in the pursuit of bait causing the magnetic attraction to break thereby causing said pivot plank to rotate causing said rodent to drop into said receptacle located below said rectangular box.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Detailed descriptions of the preferred embodiment are provided herein. It is to be understood, however, that the present invention may be embodied in various forms. Therefore, specific details disclosed herein are not to be interpreted as limiting, but rather as a basis for the claims and as a representative basis for teaching one skilled in the art to employ the present invention in virtually any appropriately detailed system, structure or manner.
Referring now to FIG. 1 we see a perspective view of the invention 100 where a rodent 4 is climbing up a ladder type ramp 2 to enter an open topped rectangular box 8 and walk along pivot plank 10. It should be noted that other types of standard ramps or ropes can also be used in this invention. A receptacle 6 holds the rectangular box up off the ground. Carry handle 14 located on lid 12 can swivel about pivot points 22, 24. An additional tab 110 and retaining clasp 112 attach the rectangular box to the receptacle allowing the user to lift the entire invention 100 including the receptacle 6. This feature can be particularly helpful if the trap is placed in a recessed location such as below a manhole. A retaining pin 18 is pushed through apertures 20, 21 to keep the lid 12 attached to the rectangular box 8 when a person is carrying the invention 100. Obviously, other standard carrying means may be employed may be used in place of the carry handle shown. FIG. 2 shows an exploded view of the invention 100. In this view it can be seen that pivot plank 10 includes centrally located apertures 17, 19 so that pivot pin 16 to can rotatably engage with pivot plank 10. The far half of the box floor 51 of rectangular box 8 has been removed so that there is room for pivot plank 10 to swing down when a rodent forces it to do so. The pivot point 16 is slightly more than half way from the front surface of the rectangular box 8 so that the weight of the far end of the plank 10 as well as the additional weight of a magnet 26 causes the plank to automatically reset itself after a rodent has forced it down. As the rodent travels down plank 10 in search of food 70, the rodents head and forearms are caused to wedge themselves between a guide plate 44 and the plank 10 as seen more clearly in the side section view of FIG. 5. Referring back to FIG. 2 we see that a magnet 26 can be placed on the underside of plank 10 so that it can magnetically interact with the ferrous metal floor portion 50 of box 8. The strength of the magnet 26 is such that a heavier rodent such as a rat will not dislodge the plank 10 until it is at the far end near the food source 70. If the user of the trap 100 wants to catch a mouse, which is lighter, he or she can use magnet 28 and insert it into receptacle 30. Additional adjustments may be made regarding pivot plank deployment by inserting magnet 28 into a choice of other receptacles 31, 33 which will cause the pivot plank to swing down by responding to a heavier or lighter weight rodent respectively. When the location of magnet 28 is closer to pivot point 16, a lighter weight at the far end of plank 10 will cause magnet 28 to disengage from the ferrous metal portion of box floor 50. FIG. 3 shows the underside of lid 12 where angled and sharp tipped wire panels which act as one way enforcement guides are positioned to cause the rodent to move forward toward the end of plank 10 and not backward. Apertures 64, 66 accept a hinge member 48 that keeps the end of lid 12 in a hinged relationship to the end of box 8. The hinge allows the lid to lift when an extra large rodent attempts to get near the bait 70 in the trap 100. Referring to FIG. 4 we see a side section view of the invention 100. We can see that box 8 is resting on receptacle 6 which in this case is filled with water 80. Climbing ramp 2 is affixed to the top ledge of box 8. Guide panel 44 can be clearly seen as can be food tray 46. FIG. 5 shows a rodent 4 that has climbed ramp 2 and walked most of the length of plank 10. The rodent's head and body is forced between guide plate 44 and plank floor 10. Angled one way enforcement plates 60, 62 make it so that the rodent can't turn back to the entrance. The combination of the rodent's weight and the muscular movements of the rodent in its attempt to reach the bait 70 cause the magnetic attraction of magnet 26 to the ferrous metal portion of box floor 50 to break thereby causing pivot plank 10 to rotate as shown in FIG. 6, sending rodent 4 to a watery grave. When pivot plank 10 rotates down, a portion of it comes into contact with lid edge 76 thereby restricting the movement of plank 10 and insuring that it will rotate back to its start position as shown in FIG. 5. Of course, the owner of the present trap 100 can elect to leave the receptacle 6 empty and to remove the live rodent and release it in a remote location. Alternately, the receptacle 6 can be made air tight thereby asphyxiating the rodent. The user may also choose to use another liquid other than water. If the user wants to maintain the life of the rodent, he or she may elect to include food for the rodent in the bottom of the receptacle 6. FIG. 7 shows an alternate embodiment of the invention 100 where the invention 100 is attached to a lid 320 so that the lid can be affixed to a standard five gallon pail 310. Obviously, other diameter lid can be sized to fit on other standard trash cans. Additionally, the invention 100 can be scaled up or down to more efficiently catch larger or smaller rodents. For example, a smaller device can be designed specifically for mice and be small enough to be used in a home environment such as a kitchen or the like and not be obtrusive. In the above described and illustrated way, the present invention easily catches rodents of varying weights and sizes and deposits them in a receptacle. The trap then automatically resets itself and is ready to catch the next rodent without the need for human intervention.
While the invention has been described in connection with a preferred embodiment, it is not intended to limit the scope of the invention to the particular form set forth, but on the contrary, it is intended to cover such alternatives, modifications, and equivalents as may be included within the spirit and scope of the invention as defined by the appended claims.
