Pest Control Apparatus
The present invention relates to pest control apparatus for trapping rodents especially rats and mice.
A known pest control apparatus comprises a hollow elongate channel member, open at opposite ends and having a removable top cover affording access to a rodent trap for the purpose of setting the trap and releasing any trapped rodents caught in the trap.
Because the trap is enclosed within the channel member, it is not possible to tell whether it has been triggered without removing the cover. Furthermore, for certain types of sensitive traps, subsequent fitting of the cover after setting of the trap can trigger the trap necessitating a repeating of the process until the trap is successfully set and the cover replaced without triggering the trap.
The present invention aims to provide an improved pest control apparatus.
Accordingly, the present invention provides a pest control apparatus for trapping rodents and comprises a housing enclosing a rodent reception space and having at least one opening for entry of a rodent into the reception space and having within the rodent reception space at least one trap of a type that requires to be set, usually against spring bias, and characterised by setting means co-operable with the trap for setting it and by the setting means being operable from a position external to the rodent reception space.
More particularly the setting means may be moveable between a trap-released position and a trap-set position and vice versa whereby from an external visual inspection of the position of the setting means it is possible to determine whether the trap is set or un-set. To that end, the setting means is acted on by the trap to move it to the trap-released position when the trap is triggered.
Conveniently, the housing is an elongated channel and the opening is in one end. Preferably there is an opening in the opposite ends of the channel. Conveniently, the housing comprises an inverted, rectangular-section channel member having a top and
depending side walls. Conveniently, the side walls have turned-in portions to provide ground-supporting flanges. Conveniently, the trap is mounted spanning the walls or supported on said turned portions. Preferably the housing accommodates two traps mounted in-line, one after the other, and positioned as a minor image: that is, with the lead-in ramp facing respective end openings of the housing. Conveniently, a respective setting means is provided for each trap.
More particularly, the setting means may comprise a transverse bar extending across the channel, the opposite ends of which are received in a respective slot in the side walls. Conveniently, the slot is curved and, for example, extends from a position adjacent to the top to a position remote from said top, maybe firstly with a gradual incline and then with a sharper radius. In use, the transverse bar typically co-operates with a setting mechanism of the trap. Connected to the transverse bar is an operating lever which is, for example, generally of an inverted U-shape. The transverse bar is positioned in the slot adjacent to the top when the trap is un-set, and remote from the top when the trap is set. h the set position the bar is moveable along part of the slot.
An embodiment of the present invention will now be described in detail by way of example only, with reference to the accompanying drawings, which:
Figure 1 is a partially broken-away perspective view of apparatus embodying the invention.
Pest control apparatus embodying the invention comprises a channel member 1 having a top 3, two downwardly depending side walls 5,7 having three lower in-turned flange portions 9 along each bottom edge of the side wall. The opposite ends 11,13 of the channel 1 are sufficiently open to admit a rodent of the type for which the trap is designed, hi use the channel is placed on the ground or other support surface. The position is chosen that is most likely to be part of a rat run. The pest control device is intended for catching the likes of rats and mice. It could be used for other rodents if suitably sized up.
In the illustrated embodiment the channel is adapted to received two proprietary mouse traps of the type that require setting and comprise a base plate, a trigger plate and a stun bar/actuating bar. Other types of trap may be employed and devices could include a
purpose-designed trap as opposed to receiving a proprietary trap as a complete but separate unit mounted therein.
hi the illustrated embodiment, the two traps are orientated in opposite directions so that the trigger plate/entrance ramp to the trap is adjacent to the respective open ends of the channel. By this means, a rodent entering the channel from either end is likely to trigger one or other of the traps.
In order to facilitate setting of the respective traps, a setting means is provided for each trap and this comprises a transverse bar 17 whose opposite ends are guided for movement in a slot 19 in each of the walls 5,7. The slot is arcuate and extends from a position adjacent to the top 3 to a position remote from it and adjacent to the lower edge of the side walls 5,7. The transverse bar connects with an actuating member 21 comprising a transverse element 23 and two legs 25,27 connected at one end to opposite ends of the transverse element and whose other ends connect with the ends of the transverse bar 17. The actuating element is disposed externally of the channel member and the transverse bar is positioned for co-operating engagement with the setting mechanism of the trap contained within the channel. Thus pushing on the actuating element causes the trap to be set as the transverse bar moves along the slot 19 as represented by Arrow A. In the set position the transverse element sits adjacent to the top with only limited movement available as represented by Arrows B,B-
It will be seen from the illustration that by simply observing the position of the actuating member, more particularly the position of the transverse bar 17, it is possible to determine whether the trap is set and/or whether it has been triggered since the actuating element is displaced from the set position shown in the right-hand side of the illustration to the un-set position as shown in the left hand side of the illustration when the trap is triggered.
