This invention relates to cage-type animal traps of the kind generally used outdoors for trapping small to medium sized animals using bait placed inside the trap.
Wire mesh cage traps have been used for decades as a means of trapping problem animals so that they can be relocated and released at another location. Such traps commonly comprise a cage of metal wire mesh or the like with an entry door at a forward end of the trap and a closed rearward end. The entry door is held open by a trigger mechanism until an animal is lured into the trap by suitable bait which is placed between the rearward end of the trap and the trigger mechanism as part of the trap setting procedure. After the animal enters the interior of the trap to reach the bait, the animal's weight pressed against the trigger actuates a trip which releases and closes the entry door, thereby trapping the animal inside the cage. Traps of this type include the Havahart® Model 1079 and the Havahart® EASY SET® live animal cage traps, both of which are manufactured and sold by Woodstream Corporation of Lititz, Pa., which is the assignee of the instant invention. The Havahart® EASY SET® live animal cage trap is described and illustrated in U.S. Pat. No. 7,757,427 (“the '427 patent”), the disclosure of which is hereby incorporated by reference as if fully set forth herein in its entirety.
The entry door on cage traps like the Havahart® Model 1079 and Havahart® EASY SET® live animal cage traps is hingedly connected to the body of the trap. Traditional door attachment methodology included the use of wire clinching clips that are placed around a wire bar of the trap body and an adjacent wire bar on the edge of the door. While these clips work effectively with smaller diameter wire, they limit the maximum size of the wire gauge combinations that can be clipped together to form a correctly functioning hinge mechanism.
Therefore, a need exists for an improved entry door hinge that can accommodate larger wire gauge combinations while creating an effective hinge mechanism.
In view of the foregoing, the present invention is directed to a cage-type animal trap that includes a wire mesh animal enclosure defined by a trap body made up of a base, a pair of opposed sidewalls emanating from the base, a rear wall secured to the sidewalls and the base, a roof secured to the tops of the sidewalls and the rear wall, and a front end defined by the base, sidewalls, and roof which is provided with an animal access opening. An entry door is movably mounted at the front end and operates in an opened position to reveal the animal access opening and in a closed position to block the animal access opening. The trap body and the door are made of a plurality of spaced wire bars as is known in the art.
As used herein, the terms “front” and “forward” refer to that end of the trap having the entry door while “rear” and “rearward” refer to the end of the trap opposite the front end. The term “longitudinal” refers to that direction corresponding with the length of the trap from the front end to the rear end thereof, while the term “lateral” refers to a direction substantially perpendicular to the “longitudinal” direction. As used in connection with direction or the relationship between two directions, the term “substantially” is defined as being nearly that of the stated value or parameter as would be understood upon visual observation by the person of ordinary skill in the art but not requiring mathematical precision with respect to the stated value or parameter.
The trap also has a setting mechanism that is coupled to a trip mechanism for initiating activation of trap closure. When tripped, a torsion spring or other mechanism urges the entry door toward its closed position. Once closed, a locking yoke is typically provided that prevents an animal caught within the trap from forcing the entry door open from inside the trap.
According to the present invention, the entry door is mounted at the front end of the trap using a hinge mechanism that has a door mounting portion, a roof mounting portion and a substantially planar body portion that joins the door mounting portion and the roof mounting portion. The body portion, which is preferably formed integrally with the mounting portions, such as by formed sheet metal, is substantially parallel with the roof of the trap when the hinge mechanism is mounted thereon.
The door mounting portion includes a front edge having a J-hook configuration with longitudinally extending slots at spaced intervals that correspond with the spacing of the longitudinally extending wire bars on the trap body such that the longitudinally extending wire bars are accommodated within the slots when the hinge mechanism is mounted. The J-hook shape, which is evident when the front edge is viewed laterally, i.e., from the side of the trap, is configured to receive the laterally extending wire bar at the upper edge of the door and to work cooperatively with a laterally extending wire bar on the roof of the trap. In properly positioning the upper edge bar of the door relative to the roof bar, the J-hook also provides clearance to allow rotational movement of the upper edge door bar relative to the roof bar as the door moves between the open and closed positions. By adjusting the size of the J-hook, virtually any wire gauge combination of the door and the trap body can be clipped together to create an effective hinge mechanism.
With respect to the trap entry door, it is understood that the longitudinally extending wire bars on the door are substantially parallel with the longitudinally extending wire bars on the trap body when the door is in the open position. However, this substantially parallel relationship does not apply when the door is in the closed position due to the door being angled downwardly from its hinged connection with the trap to a bottom edge of the door to close the animal access opening. However, for ease of description, the wire bars on the door that are substantially parallel with the longitudinally extending wire bars on the trap body when the door is open are referred to as the longitudinally extending door wire bars.
The roof mounting portion of the hinge mechanism includes a plurality of spaced attachment tabs formed at the rear edge of the body portion. Prior to being mounted on the trap, the attachment tabs extend substantially perpendicular to the body portion, creating an elbow joint, and are separated from one another by slots. Like the slots in the door mounting portion, the slots in the roof mounting portion are also positioned at spaced intervals that correspond with the spacing of the longitudinally extending wire bars on the trap body. Thus, the longitudinally extending wire bars on the roof of the trap body are accommodated within the slots when the hinge mechanism is positioned on the roof for mounting, while the attachment tabs extend downwardly toward the base of the trap body. The elbow joint between the body portion and the tabs is placed closely rearward of and generally parallel with a laterally extending wire bar of the roof. To complete the mounting of the hinge mechanism, the attachment tabs are curled around the adjacent laterally extending wire bar, effectively bending them forwardly along the elbow joint to lap under the body portion, thus securing the hinge mechanism to the trap body.
Once secured to the trap in this way, the hinge mechanism creates a more precise axial location of the hinge pivot at the door mounting portion for improved hinge action and more repeatable setting and tripping action as compared with conventional wire clinching clips. The hinge mechanism also provides greater trap stiffness at the hinge, improved rigidity of the hinge mechanism and trap door, and reduced friction in the hinge pivot.
Accordingly, it is an object of the present invention to provide a wire mesh animal cage trap with a hinge mechanism having a door mounting portion, a roof mounting portion and a substantially planar body portion that joins the door mounting portion and the roof mounting portion, the door mounting portion hingedly securing the trap entry door to the trap body and the roof mounting portion securing the hinge mechanism to the roof of the trap.
Another object of the present invention is to provide a wire mesh animal cage trap with a hinge mechanism in accordance with the preceding object in which the door mounting portion includes a front edge having a J-hook configuration with longitudinally extending slots at spaced intervals that correspond with the spacing of the longitudinally extending wire bars on the trap body such that the longitudinally extending wire bars are accommodated within the slots when the hinge mechanism is mounted.
Still another object of the present invention is to provide a wire mesh animal cage trap with a hinge mechanism in accordance with the preceding object in which the J-hook shape of the door mounting portion is configured to receive the laterally extending wire bar at the upper edge of the door and to cooperate with a laterally extending wire bar on the roof of the trap while providing clearance to allow unhindered rotational movement of the upper edge door bar relative to the roof bar as the door moves between the open and closed positions, the size of the J-hook being selected to enable virtually any wire gauge combination of the door and the trap body to operate smoothly together.
Yet another object of the present invention is to provide an animal cage trap with a hinge mechanism in accordance with at least one of the preceding two objects in which the roof mounting portion includes a plurality of spaced attachment tabs formed at the rear edge of the body portion, the attachment tabs being bendable to secure the body portion flatly on top of the roof of the trap when the hinge mechanism is mounted thereon.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout.
It is to be understood that the embodiments described herein are disclosed by way of illustration only. It is not intended that the invention be limited in its scope to the details of construction and arrangement of components set forth in the following description or illustrated in the drawings. Also, in describing the preferred embodiments, specific terminology will be resorted to for the sake of clarity. It is to be understood that each specific term includes all technical equivalents which operate in a similar manner to accomplish a similar purpose.
An animal cage trap having a hinge mechanism according to the present invention is shown in
The entry door 26 is movably mounted at the front end 24 of the trap by a hinge mechanism generally designated by reference numeral 40. The entry door 26 operates in an opened position to reveal the animal access opening and in a closed position to block the animal access opening. The components of the trap which are operative to trap and contain an animal correspond with those found in the Havahart® Model 1079 trap which has been commercially available for many years.
The front edge 57 of the door mounting portion 42 includes the J-hook 48 which creates the axle for the hinge mechanism when the upper edge laterally extending wire bar 50 of the door 26 is received in the J-hook as representatively shown in
As mounted to the trap as shown in
The J-hook 48 and body portion 46 include longitudinally extending slots 58 and 60 at spaced intervals that correspond with the spacing of the longitudinally extending wire bars 52 on the roof 22 of the trap body. According to a preferred embodiment shown, the center slot 60 is wide enough to accommodate two spaced longitudinally extending roof bars (see
The front edge 57 of the door mounting portion 42 also has cutouts 62. These cutouts are formed to accommodate the ends 27 (see
The attachment tabs 54 formed on the rear edge 64 of the roof mounting portion 44 of the hinge mechanism are also spaced from one another by slots 66 as best seen in
The body portion 46 of the hinge mechanism 40 is substantially planar and extends between the door mounting portion 42 and the roof mounting portion 44. According to the embodiment shown, the longitudinal length of the body portion extends between two adjacent laterally extending roof bars so that the J-hook curves around the forward bar 52 and the attachment tabs 54 are curled around the rearward bar 56 (see
With the upper edge bar 50 of the door captured in the J-hook 48, the hinge mechanism 40 is lifted upwardly while keeping the roof mounting portion 44 elevated. As the hinge mechanism 40 comes up, the longitudinally extending bars 30 effectively “move down” the slots 58, 60 until the bars reach the front edge 57 of the door mounting portion 42 and the upper edge door bar is adjacent the laterally extending roof bar 52. The hinge mechanism is then rotated to lower the roof mounting portion 44, bringing the elbow joint adjacent and generally parallel with the laterally extending wire bar 56 of the roof so that the attachment tabs can extend downwardly toward the base of the trap as shown in
As a final assembly step, the attachment tabs 54 are bent or curled forwardly along the elbow joint to lap under the body portion and capture laterally extending roof bar 56 as shown from a view taken inside the trap in
The foregoing descriptions and drawings should be considered as illustrative only of the principles of the invention. The concepts disclosed herein may be modified to suit other specific trap designs as may be apparent to those skilled in the art. Therefore, it is not desired to limit the invention to the specific examples disclosed or the exact construction and operation shown and described. Rather, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
