Telltail rodent trap

Abstract

Telltale rodent trap for trapping rodents in interior walls, ceilings and similar spaces including a baited and set spring-loaded trap attached to a base plate passing through a wall or ceiling opening to be exposed to interior spaces frequented by rodents. A cover plate having a telltale aperture fits over the opening. An elongated telltale is attached at one end to a trap arm pivoting between a first position when the trap is set and a second position when the trap is sprung. The other end of the elongated telltale is inserted between the cover and base plates and is visible in the telltale aperture of the cover plate. When the trap is sprung, the trap arm pulls the elongated telltale so it is no longer visible in the telltale aperture indicating that a rodent has been trapped and the trap assembly should be removed and reset.

Description

FIELD

• • This invention relates to a rodent trap system for tapping rodents in interior walls, ceilings and similar spaces that includes visible means of detecting when the trap has been sprung.

BACKGROUND

German OS DE 10-2012-013-138 A1 (2014) describes a rodent trap usable in wall and ceiling interiors which includes a strip that hangs from a wall or ceiling and disappears when the trap has been sprung. Besides being unsightly, the strip can be tampered with by pets or children which can cause the trap to prematurely spring without doing its job.

SUMMARY

The invention provides a telltale rodent trap system for trapping rodents in interior walls, ceilings and similar spaces. A cover plate which fits over an opening in a wall or ceiling has a telltale window or aperture that can be easily be seen from the inside of the room or interior space. A base plate is attached to the back of the cover plate and is sized to fit into the opening in the wall or ceiling. One aspect of the invention is to determine the location of an interior space being frequented by rodents (like mice in the ceiling or a wall) and creating the opening into which the base plate will fit and be covered by the cover plate.

Flexible lateral wings are attached to the rear or back-side of the base plate, made, for example, from two sections or one piece of 10 mil HDPE or similar plastic, can be folded towards and pass through the wall or ceiling opening and thereafter unfold against the back surface of the wall or ceiling to hold the trap system in place until it needs to be removed to extract a taped rodent. The cover plate can include a handle or similar means to facilitate removal although flexibility of the wings allows the cover plate to be pried up without a handle or similar means.

A conventional spring-loaded rodent trap (rat or mouse), or a “better mouse trap” such as described in U.S. Pat. No. 8,490,322 and sold under the trademark “Tomcat”, is preferably releasably attached to the back of the base plate using, for example, “Velcro” or a similar hook and eye or nub systems. The trap is sized to fit thru the wall or ceiling opening and has a trap arm which pivots between a first position when the trap is set and a second position when the trap is sprung.

An elongated telltale is attached at one end to the pivoting trap arm and extends therefrom between the cover and base plates such that it is visible in the telltale window of the cover plate when the arm is in the set position and no longer visible when the arm is in the sprung position. In other words, the telltale is pulled away from the telltale opening when the pivot arm is released to spring the trap.

The telltale, which can be a strip of colored plastic or the like, has a first color, like blue or green, and the surface of the base plate under the telltale window has a different, preferably contrasting, second color, like red, or orange or so-called neon versions of red and orange. Thus when the second color is displayed in the telltale window, the homeowner is told that the trap has been sprung and it is time to remove the trap assembly and discard the trapped rodent (mouse, rat, vol and similar pesky animals). The trap can be rebated and set, or discarded and replaced by a new trap, and the assembly reinserted in the wall or ceiling opening to catch more rodents.

Prompt removal of a trapped rodent is essential to avoid decomposition and attendant unpleasant odors which can last for days and weeks. The disappearance of a dangling telltale strip can easily go unnoticed whereas the invention provides a positive and readily visible means that says remove the dead rat or mouse now.

The invention also provides a process for trapping rodents in interior walls, ceilings and similar spaces. The first step is to create an opening in a wall or ceiling to gain access to an interior space frequented by rodents. The opening should be between wall studs or ceiling rafters which can be located using known locating devices or by trial and error. Next is to provide a spring-loaded trap assembly as described above.

After baiting and setting the trap, the lateral wings are folded to insert the trap assembly into the wall or ceiling opening. The wings then unfold against the back surface of the wall or ceiling to hold the trap assembly in place.

An elongated telltale is attached and inserted between the cover and base plates as described above. When the telltale is no longer visible, indicating that the trap has been sprung, the trap assembly is removed or extracted from the wall or ceiling opening by causing the flexible wings to fold and allow the trap assembly to be removed.

The trap can be rebated and set, or discarded and replaced by a new trap, and the assembly reinserted in the wall or ceiling opening to catch more rodents.

DESCRIPTION OF THE DRAWINGS

The present invention will be more fully understood from the accompanying drawing and the following description wherein:

FIG. 1A is an exploded, perspective view of one embodiment of the trap system of the invention, and FIGS. 1B-1D are perspective views showing alternate embodiments of the telltale opening in the cover plate;

FIG. 2 is a perspective view of the trap assembly of FIG. 1 inserted into an interior space between wall or ceiling studs or rafters with the trap in the sprung position;

FIG. 3 is the same as FIG. 2 with both wings engaged and the trap in the set position;

FIG. 4 is a composite sectional view showing the trap assembly with wings folded for insertion into a wall or ceiling opening and then partially unfolded on the way towards lying flat to hold the assembly in place; and

FIGS. 5 and 6 are plan views of a cover plate with a telltale window indicating a trap is set (FIG. 5) and when it has been sprung (FIG. 6).

DESCRIPTION

Referring now to the preferred embodiment shown in FIGS. 1-4, the trap system is seen to include a cover plate 14 adapted to fit over an opening 12 in a wall or ceiling 10 which has a telltale window or opening aperture 16 visible from the outer side of cover plate 14. Base plate 18 is attached to the back of cover plate 14 and is adapted to fit into opening 12. Opening 12 can easily cut from drywall or similar wall or ceiling material, using a shop knife or saw after locating the studs or rafters 30.

Flexible lateral wings 20, shown in a preferred embodiment as a single piece of flexible plastic, are attached to the rear of base plate 18 and are adapted to fold towards and pass through opening 12 and thereafter unfold against the back surface of a wall or ceiling 10 to hold the trap system in place in opening 12 (FIG. 3).

Spring-loaded trap 24 is preferably releasably affixed to the back of base plate 18 and is sized to fit through opening 12. Trap 24 has arm 26 adapted to pivot between a first position when the trap is set (FIG. 3) and a second position when the trap is sprung (FIG. 2).

Elongated telltale 22 is attached at one end to trap arm 26 and extends therefrom between cover and base plates 14 and 18. Telltale 22 is visible in telltale window 16 when arm 26 is in the set position (FIG. 3) and no longer visible in window 16 when arm 26 is in the sprung position (FIG. 2). Telltale 22 is thus pulled away from telltale opening 16 when pivot arm 26 is released to spring the trap. Telltale 22 can simply lie on the surface of base 18 to be visible through window 16 or a slot or groove can be provided to position the telltale under window 16 (FIG. 4). See FIGS. 5 and 6.

Telltale 22, which can be a strip of colored plastic or the like, has a first color, like blue or green for example (FIG. 5), and the surface of base plate 18 under telltale window 16 has a different, preferably contrasting, second color 32 (FIG. 6), like red, or orange or the so-called neon versions of red and orange. Thus, when the second color is displayed in telltale window 16, the homeowner is told that the trap has been sprung and it is time to remove the trap assembly and discard the trapped rodent (mouse, rat, vol and similar pesky animals). Trap 24 can be rebated and set, or discarded and replaced by a new trap, and the assembly reinserted in the wall or ceiling opening to catch more rodents.

Telltale opening 16 can be rectangular as shown in FIG. 1A, and it can be any shape desired such as square (opening 16a in FIG. 1B), round (opening 16b in FIG. 1C), oval (opening 16c in FIG. 1D) or the like. Telltale 22 will then have a width sufficient to fill the window 16 when the trap is set.
