BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention pertains to animal traps and more specifically, it pertains to wireless rat traps that transmit a signal to a remote receiver when movement of the trap over a support surface occurs.
2. Description of the Related Art
When a rat is caught by a spring-loaded trap, the rat instinctively tries to escape by using its rear legs to free itself. As the rat tries to free itself, the trap is pulled rearward before the rat dies.
Heretofore, rat traps that produce an audio signal when activated have been patented (See U.S. Pat. No. 6,137,415). One drawback with these traps is that the sound generated may be heard by other individuals alerting them that the area is infested with rats. Another drawback is that sound produced when activated may not be heard from a remote location. A trap that discreetly informs an operator in a private location that a rat has been caught is more desirable. Also, when multiple sound generating traps are used in a small area, identifying which particular trap has been activated can be difficult.
In a warehouse infested with rats, multiple rat traps are often deployed in different locations of the warehouse. In the prior art, a warehouse worker must visit the different areas on a regular basis to determine if a rat has been caught.
What is needed is a rat trap system that uses standard, inexpensive, spring-activated rat traps that can be set-up in different locations in a rat infested area that informs the operator when the trap has been activated.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide a spring-loaded, rat trap movement detection system that detects and generates an alarm or notice when the trap has been moved.
It is another object of the present invention to provide such a system that can be used with multiple rat traps set-up in different locations in a rat infested area.
It is a further object of the present invention to provide such a system that uses wireless technology that allows the status of the traps to be monitored from a central location.
It is still a further object of the present invention to provide such a system that can be coupled to a local area network that communicates with traps in the rat infested area thereby enabling the operator to monitor the status of the traps via his or her computer or ‘smart’ cellphone.
These and other objects are met by the wireless trap movement detection system that includes one or more spring-loaded rat traps setup in an area known or believed to be infested with rats. The system includes a wireless transmitter mounted inside a transmitter unit placed in a rigid support surface in an area considered to be infested with rats. Positioned over the top surface of the transmitter unit is lightweight, spring-loaded rat trap. When a rat is caught by the trap, the movement of the spring causes the trap to move or the rat physically drags the trap over the top surface of the transmitter unit. Mounted on the top surface of the transmitter unit is a spring-loaded plunger switch. The plunger switch is located on the top surface so that when the trap is placed over the top surface of the transmitter unit, the plunger switch is forced downward into an OFF position. When the trap falls off or moves a short distance over the top surface of the transmitter unit, the plunger switch is released thereby enabling it to automatically move to an ON position. The plunger switch is coupled to the wireless transmitter located inside the transmitter unit. When the plunger switch is in the OFF position, the transmitter is either de-activated or continuously transmits a ‘non-activated’ code wireless signal. When the plunger switch is in the ON position, the transmitter is activated and begins transmitting an ‘activate’ code wireless signal.
The system also includes a wireless receiver located in the vicinity of the transmitter unit that monitors the area for a wireless signal from the wireless transmitter. In one embodiment, the wireless receiver is a stand alone unit setup in a monitoring location near the rat infested area. The wireless receiver is designed to communication exclusively with one or more transmitter units. When a signal is received from the transmitter unit, a light or sound indicator on the wireless receiver is activated that informs the operator that the trap on the transmitting unit has been moved. In one embodiment, the light or sound indicator on the wireless receiver is linked to one particular transmitter unit so that the operator may determine by viewing the activated lights or sounds which particular transmitter unit has been activated. In this embodiment, a network adaptor port and necessary software programs and drivers may be supplied with the wireless receiver that allows the wireless receiver to be connected to a network router, a desktop computer, or a laptop computer and monitored therewith.
In a second embodiment, an enhanced transmitter unit is used that is able to communication with a wireless router setup within the rat infested area. Accompanying the enhanced transmitter unit is a rat trap transmitter control software program that is loaded into the memory of a desktop or laptop computer that is able to connect to the local area network and the wireless router. The rat trap transmitter control software program is to program each transmitter unit so that it may communicate with the wireless router and join the local area network. During operation, the OFF or ON status of the plunger on the transmitter unit is communicated to the wireless router and then presented in a menu page on the desktop or laptop computer created by the rat transmitter control software program. The rat transmitter control software program may interface with an email program on the desktop or laptop computer so that when plunger is moved to the ON position, a notification is sent to the operator via his or her email account.
The system is designed so that the operator may monitor one trap or a plurality of traps. In the preferred embodiment, each transmitter unit is assigned an identification code that is recorded in the wireless receiver unit or on the rat transmitter software program that identifies the transmitter unit generating the activation code signal.
Because the system disclosed herein may interface with a local area network, the system may be easily adopted by pest control companies that hire individuals to monitor the traps in multiple locations.

DESCRIPTION OF THE PREFERRED EMBODIMENT(S)
Referring to the FIGS. 1-9, there is shown the wireless rat trap movement detection system 10 that includes a spring-loaded rat trap 12 positioned at a known or suspected rat infested location 20 of a small building (shown as a detached garage 15 in FIG. 1) or large building (shown as a warehouse 15′ in FIG. 2). The system 10 includes a wireless transmitter 25 mounted inside a transmitter unit 22 on which a spring-activated rat trap 12 is placed. The transmitting unit 22 includes a rigid rectangular body 24 with a flat top surface 27 and a flat bottom surface 28.
Mounted on the top surface 27 of the body 24 is a spring-loaded, single pole momentary switch 29. The switch 29 includes a spring-loaded plunger 31 that is biased upward by a spring 33 and extends above the body's top surface 27. When a standard rat trap 12 is placed over the top surface 27, the weight of the trap 12 overcomes the biasing force of the spring 33 thereby retracting the plunger 31 inside the body 24. The switch 29 includes contacts (not shown) that cause the switch 29 to close when the plunger 31 extends upward from the body 24 and close when the plunger 31 retracts into the body 24. Mounted inside the body 24 is a PCB 35 with a wireless transmitter 25 integrally formed or mounted thereon. The transmitter 25 produces a wireless signal 32 containing an identifying code 34. The PCB 35 is connected either to internal batteries 37 or to an external electrical adapter 37′ that provides a D.C. electric current to the PCB 28, the transmitter 25 and the switch 29. Mounted on the side of the body 25 is an optional manual switch 38 so that the transmitter Unit 22 may be selectively activated and de-activated.
The system 10 also includes a receiver unit 50 that is placed inside the monitoring area 16, 16′ inside the house 15 or warehouse 15′, respectively. In the monitoring area 16, 16′, the status of the trap 12 located above the transmitter unit 22 is monitored by monitoring the status of the transmitter unit 22. As shown in FIGS. 4-6, the receiving unit 50 includes an outer housing 52 that contains a wireless receiver 55, an LCD display 60, an antenna 65, a manual ON/OFF switch 70, and an A.C. electric power source 75. In one embodiment, the receiver 55, the LCD display 60, the switch 70 and the A.C. electric power source 75 (a pair of electrical plugs) are connected to the PCB 58.
Mounted on the front face of the outer housing 52 is one or more indictors (80-86) that are aligned and registered with identification information (Numbers 1, 2, 3, and 4) also printed on the front face.
In one embodiment, the system 10 is designed for use by an operator who wishes to monitor one to four spring-loaded traps 12 in areas where rats visit or live. In another embodiment, the system 10 is designed for a large building (warehouse 15′) where multiple traps 12A-12D are set-up. In both embodiments, the receiver unit 50 is able to receive multiple wireless signals 32A-32D from a plurality of wireless transmitter units 22A-22d, respectively. When one of the signals 32A-32D is detected, the indicator 80-86 that corresponds to the signal is activated, thus informing the operator that the spring-loaded trap 12 located over the transmitter unit 22A-22d has been sufficiently moved so that the plunger 31 is extended. The trap 12A-12D may then be visited and if necessary, reset.
FIG. 7 is a side elevational view of the receiver unit 50 showing the movement of the spring-load rat trap 12 over the transmitter unit 22 that causes the plunger switch 29 on the transmitter unit 22 to move from an OFF position to an ON position and transmit a wireless signal 32. During set-up, the manual switch 38 on the receiving unit 50 is turned OFF. The receiver unit 50 is then placed on a rigid surface 99 with the top surface facing upward. A ‘set and baited’ spring-loaded rat trap 12 is then longitudinally aligned and registered over the unit's top surface 27 so that the trap's platform 13 extends over and presses the plunger 31 downward. The manual switch 38 is then manually moved to the ON position. As shown in FIG. 3, the plunger switch 29 and plunger 31 are located near one edge of the body 24. When the trap 12 is positioned over the body 24, the trap 12 is aligned so that when a rat is trapped, the trap's platform 13 only has to travel a short distance longitudinally over the body 24 to release the plunger 31. Research by the inventor indicates that when trapped, the rat's hind legs presses against the rigid surface, and the dynamic contraction of the rat's muscle pulls the platform 13 rearward over the top surface 27 of the transmitter unit 22. When the edge of the trap 12 clears the plunger 31, the plunger 31 is released and the plunger switch 29 causes transmission of a wireless signal 32 from the transmitter unit 22 which is received by the receiver 50 in the receiver unit 50.
FIG. 8 is an illustration showing a second embodiment of the system, denoted 10′, in which the receiver unit 50 communicates with three transmitter units 22A, 22B and 22C associated with traps 12A, 12B, 12C, respectively, and connected to a computer 101 with a display 102. The receiver unit 50 includes a network adaptor port 92 that connects via a cable 94 to the computer 101. Loaded into the working memory of the computer 101 is a receiving unit communication software program 106 that receives transmitter unit status information 108 from the receiver unit 50 and presents the information in a menu 110 shown on the display 102
FIG. 9 is an illustration showing a third embodiment of the system, denoted 10′′, in which the transmitter unit 22 described above is replaced by an enhanced transmitter unit 120 that is able to communicate and transfer data to a wireless router 130 that connects to a local area network 140. Connected to the local area network 140 is a computer 101 with a display 102. The local area network 140 may be connected to a wide area computer network 150 (such as the World Wide Web) which enables remote computers 160 to communicate with the desktop computer 101 or directly with the enhanced transmitter unit 120. The system 10′′ may also include a smart cellular telephone 180 (with email, MMS or SMS service capabilities) that connects via a wireless telephone communication network 170, to the wide area network 150.
The enhanced transmitter unit 120 includes the same components used in the transmitter unit 22 but includes a wireless network adaptor 122 (IEEE 802.11 standard or similar standards) and programmable memory 124. Loaded in to the computer 101 is a transmitter unit communication software program 126 that enables the operator to configure the enhanced transmitter unit 120 to communicate with the wireless router 130 and join the local area network 140. Also loaded into the memory of the computer 101 is an email software program 128. During setup, the operator may used the transmitter unit communication software program 126 to configure the enhanced transmitter unit 120 a message 200 via the router130 and email software program 128 that the plunger 31 has been extended and moved to the ON position. The system 10′′ is especially useful for pest terminating companies which need to monitor the status of traps in multiple buildings or when the owner is away from the building and wants to be notified when a trap has been moved.
In compliance with the statute, the invention described herein has been described in language more or less specific as to structural features. It should be understood however, that the invention is not limited to the specific features shown, since the means and construction shown, is comprised only of the preferred embodiments for putting the invention into effect. The invention is therefore claimed in any of its forms or modifications within the legitimate and valid scope of the amended claims, appropriately interpreted in accordance with the doctrine of equivalents.
