Abstract
An animal trap comprising an elongated housing having open and closed ends, a door pivotally mounted at its lower end on the housing adjacent the open end and movable between an upright closed position wherein it closes the open end and an open position wherein it is disposed within the housing in a substantially laterally extending position near the bottom of the housing. The door is biased to the closed position. A panel is pivotally connected at one end to the housing and extends generally laterally within the housing near the bottom thereof toward the closed end. An elongated pawl member is pivotally connected at one end with the adjacent end of the panel opposite to the one end thereof, and is pivotally connected at its opposite end to the housing. The pawl member has a tooth at its opposite end and is urged in an upward direction. The tooth is positioned to engage the door when it is moved to the open position to retain the door in the open position. The tooth is movable to a position wherein it releases the door to enable it to be moved to the closed position when an animal enters the housing and steps on the panel to pivotally move it and the pawl member downwardly.

Description
Background of the Invention
The present invention relates to a new and improved animal trap which can be reused or disposed of without requiring handling of the animal trapped therein.
Heretofore, although most animal traps have generally served their intended purpose, they have been subject to one or more of the following disadvantages:
1. They have been complicated in construction and thus expensive to manufacture;
2. They have been unreliable in operation;
3. They have been difficult to handle because of their weight or construction;
4. They have been difficult to set because of their construction and, in some cases, have been dangerous to the user in setting them because of a sensitive setting mechanism which can release the trap while being handled by the user; and
5. They have been so constructed as to require the handling of a dead animal caught therein if the trap is to be reused.
The animal trap of the present invention is not subject to any of the above-mentioned disadvantages and possesses many advantages not found in the traps in use at the present or in the past.
Summary of the Invention
The animal trap of the present invention preferably comprises an elongated housing formed of a lightweight, clear material such as plastic which is closed at its sides and one end. At the other end of the housing, a door is pivotally mounted at its lower portion thereon and is biased to a closed position wherein it closes the other end. Inside the housing near the one end thereof a panel is pivotally connected at one end to opposite sides of the housing and extends generally laterally within the housing.
An elongated link or pawl member is pivotally connected at one end with the free end of the panel and extends within the housing along one side thereof toward the door at the other end of the housing. The pawl member is pivotally connected to the adjacent side of the housing at its other end and is provided with a tooth at its other end. Suitable biasing means, such as a spring member, engages the pawl member and urges it upwardly which also causes the panel to assume an inclined position wherein it extends upwardly toward the one end of the housing.
When it is desired to set the trap to catch or kill an animal such as a mouse or the like, unpoisened or poisened food is placed within the housing near the one closed end thereof. The door at the other end thereof is pivoted downwardly to an open position wherein its upper free end engages the tooth on the pawl member and moves the pawl member downwardly to a slight extent against the force of the spring member to cause the tooth to move over the adjacent portion of the free end of the door to retain it in the open position.
Thereafter, when an animal enters the open end of the trap to get the food at the closed end thereof, it first steps over the open door which continues to be retained in the open position by the tooth on the pawl member. As the animal advances in the housing toward the food, it steps on the panel which pivots downwardly to cause the pawl member to pivot downwardly to an extent that its toogh moves away from the door to release it. The door then moves to the closed position to trap the animal within the housing.
The trap can be conveniently disposed of with the animal enclosed therein, or the animal can be removed from the trap to enable it to be reused.

Description of the Preferred Embodiment
As shown in the drawing, the animal trap 10 of the present invention comprises an elongated housing 12 formed of a lightweight, transparent material such as plastic or the like. The housing 12 comprises an open end 14, a closed end 16, side walls 18 and 20, a bottom wall 22 and a top wall 24. The housing 12 may be of any suitable size, depending on the type of animal to be caught therein.
At the open end 14 of the housing 12, a door 26 is pivotally mounted at its lower portion 28 on the side walls 18 and 20 of the housing. A suitable biasing means, such as a spring 30, urges the door 26 to the closed position shown in FIG. 3 wherein the door 26 engages the upper wall 24 to close the open end 14 of the housing 12.
Inside the housing 12 near the closed end 16 thereof, a panel 32 is pivotally connected at one end 34 to the side walls 18 and 20. As shown in the drawing, the panel 32 extends generally laterally within the housing 12 near the bottom wall 22 thereof.
An elongated link or pawl member 36 is pivotally connected at one end 38 with the free end of the panel 32 and extends within the housing along the side 18 thereof toward the door 26 at the open end 14 of the housing. The pawl member 36 is pivotally connected at its opposite end 40 to the side wall 18 and is provided with a tooth 42 of any suitable configuration at the end 40 thereof. Suitable biasing means, such as a leaf spring member 44 is secured to the bottom wall 22 and the pawl member 36 for the purpose of urging the pawl member upwardly which also causes the panel 32 to assume the inclined position shown in FIGS. 1 and 2 wherein it extends upwardly toward the closed end 16 of the housing.
When it is desired to set the trap 10 to catch or kill an animal, such as a mouse or the like, unpoisened or poisened food F is placed on the bottom wall 22 of the housing near the closed end 16 thereof. The door 26 at the open end 14 of the housing is pivoted downwardly to the open position shown in FIGS. 1 and 2, wherein its upper free end engages the tooth 42 on the pawl member 36 and moves the pawl member downwardly to a slight extent against the force of the spring member 44 to cause the tooth 42 to move over the adjacent portion of the free or upper end of the door to retain it in the open position.
Thereafter, when an animal enters the open end 14 of the trap 10 to get the food F at the closed end 16 thereof, it first steps over the open door 26 which continues to be retained in the open position by the tooth 42 on the pawl member 36. As the animal advances in the housing toward the food F, it steps on the panel 32 which pivots downwardly or in a counterclockwise direction as shown in FIG. 2 to cause the pawl member 36 to pivot downwardly (or in a counterclockwise direction as shown in FIG. 2) to an extent that the tooth 42 moves away from the adjacent end of the door 26 to release it. The door 26 is then moved to the closed position shown in FIG. 3 by the spring 30 to trap the animal within the housing 12.
From the foregoing description, it will be readily appreciated that the animal trap of the present invention is simple in construction, reliable in operation, easy to set, and can be formed of any suitable lightweight material such as plastic or the like. The trap can be conveniently disposed of with the animal enclosed therein, or the animal can be removed from the trap to enable it to be reused.
