Abstract: A trap for catching animals, in particular muridae, is provided with a tank and a passageway, which extends above the tank from an entry and has, at the end, a container for a bait; the floor of the passageway is defined by a gangway, which opens to let an animal fall into the tank and is provided with two trapdoors hinged to one another; the first of said trapdoors is hinged about a horizontal axis, so as to tilt from a substantially horizontal position during the opening of the gangway, and has a counterweight to reclose the gangway; the gangway has an attach device which connects the second trapdoor to a fixed retaining device, so as to support the first trapdoor in its substantially horizontal position even when the first trapdoor is subject to a weight; the attach device is releasable when the weight rests on the second trapdoor.

Abstract: A pedal rack (10) comprising a case (12) with a plurality of a variety of electronic components (14) that may be electrically connected together and retained within the case (12). A sound control unit (16) may be electrically connected to the electronic components (14). A facility (18) is for pivotally mounting the sound control unit (16) within the case (12). The sound control unit (16) can go between a generally horizontal storage position "A" over the electronic components (14) and into an upright operational position "B" for easy access. The sound control unit (16) may also be completely removed from the case (12).
